The importance of a foam generator
If you quickly go over the process of making foamed blocks, you can identify the following key elements:
- cement is mixed with water and sand;
- foam is added to the resulting liquid concrete under pressure.
The final ingredient accounts for 80% of the quality of subsequent products. As a result, a DIY foam generator for foam concrete ought to generate high-quality foam with a particular density and longevity. Furthermore, a structure that will flawlessly "get along" with any kind of foaming agent—from both domestic and foreign manufacturers—must be built. This is crucial because you can experiment with a variety of emulsions and concentrates when selecting "your" materials for foam concrete.
A superior construction foam generator is also defined by its high productivity and consistent supply of uniform foam to the concrete mixer. The end products will not be appropriate for wall construction if this process fails.
The foam generator mechanism’s efficiency has an impact on construction costs as well. Ultimately, the entire volume of the mixture is provided by the foam. Insufficient amounts or low density and durability will cause the concrete blocks to "melt" by 25% or even 50% of their original volume. Ultimately, it transpires that despite investing $1 million, they received significantly less in output. If there is functional foam concrete inside the walls, things will get much worse.
Building a structure that will mix water, air, and concentrate as precisely as possible is essential to getting good results. It is not hard to replicate a foam generator’s factory device. Nevertheless, the final mechanism assembly process necessitates meticulous attention to detail.
Constructing a DIY construction foam generator is an affordable method of creating superior foam for a range of concrete uses. With readily available materials and easy techniques, this article will walk you through the process step-by-step so you can make consistent, long-lasting foam for your projects without breaking the bank.
Types and structure of the mechanism
Based on the type of design device, all the different models of foam generators available on the market can be categorized into two major groups.
Foam generators with a cyclic intermittent principle of operation
Or receiver, as they are known. They got this moniker because, in addition to compressed air, their receiver also contains a foaming agent that depletes with each foam supply. You must shut it off, let go of the pressure, and add foam concentrate in order to refuel.
Foam generators with a continuous operating principle
We refer to these models as non-reversible models. The design itself presumes that the concentrate is supplied into the foam-generating pipe from a specially designed container when the electric pump, which takes the place of the receiver, is turned on. Since the entire process moves quickly, the foam generator is activated right before foam is added to the concrete mixer. The supply of compressed air is the actual function carried out by the reverse.
Granted, as they say, different colors correspond to different markers, but the second kind of foam-generating mechanism is more useful and convenient. It is especially suitable for people who make a lot of foam concrete in a single work shift. By producing foam with a high multiplicity while also lowering the concentration level, continuous foam generators enhance the quality of the final products. After all, the density and strength characteristics of products are greatly decreased when large amounts of any protein concentrate are added.
Blocks made of highly foam do not shrink, demonstrating their high quality and amply justifying the money spent on their creation.
Production of a foam generator
Like any other mechanism, the foam generator necessitates the planning of a specific project as well as a thorough analysis of the constructive in accordance with the schemes. They are the ones who can instruct you on how to properly and effectively construct a foam generator for foam concrete.
What is required for assembly
When choosing the required components from the garage bins or purchasing new ones, keep in mind that all the parts that come into contact with the concentrate’s working solution and the foam itself should only be made of stainless steel:
- metal sheets or finished metal container;
- pipe;
- pump and compressor;
- valves for stopping and adjusting the supply of foam;
- hoses;
- water meter;
- Laval"s nozzle;
- welding machine;
- filler for a foam cartridge – plastic bullets for a children"s gun or any other stainless steel balls with a diameter of 2 mm;
- plumbing filter.
There are certain details that need to be considered when choosing components.
Air and concentrate supply hoses are appropriate for routine use in welding operations; however, the handout that the foam passes through needs to be of superior quality, hard, and have a diameter of 10–20 mm.
The nozzle on Laval has to match:
- the depth and input hole of the nozzle should be related to 1: 1, but not less than 30 cm;
- The depth and output of the nozzle should be related to 3: 1;
- The center hole is 10 mm.
Features of phenopatron size selection:
- For performance 150-200 l: length 60-80 cm, diameter 10 -15 cm;
- For performance 350 -500 l: length 60-80 cm, diameter 15 -25 cm.
However, the filler in the pipe—rather than the pipe itself—helps turn the concentrate into foam. I frequently use mesh mesh nets in his quality. However, for the following reasons, this option is not very effective:
- rapid wear;
- become rusty after contact with concentrate;
- foam is not durable enough.
Tile-laying tiny crosses are another filler choice. At the beginning, they produce very good results, but literally after a few uses, they stick together and produce low-quality foam. It’s essential to wash your hands often with a cleaning solution.
It is best to purchase regular children’s bullets for a toy gun in order to prevent such a negative outcome. Here, there ought to be enough of them to fill the foam cannon all the way to the top. can be cleaned once every two weeks as long as it runs nonstop. This procedure has to be carried out following each downtime, when the balls firmly adhere to one another, in the event that failures occur.
The remaining components are chosen based on each generating unit’s unique design.
The principle of operation and assembly of the foam generator
You must understand the foam generator’s operating principle and the function of each structural component in order to build a foam generator for foam concrete by hand.
You can utilize a standard vacuum cleaner to provide air to the ready container, greatly simplifying the assembly process. It is important to keep in mind, though, that this kind of ploy won’t be effective in controlling raw material consumption.
On the network, there are numerous options for creating a foam generator at home out of a fire extinguisher. Unquestionably brilliant, the concept and the resulting invention are only appropriate for producing foam to wash cars. Consequently, we bring up this concept right away.
The best way to differentiate the foam generator’s design and make it more appropriate for construction use is to get a submersible pump and compressor. You will need a hose and a pump for a continuous supply of concentrate and air. The compressor will supply compressed air into the working vessel through a different hose. By using a valve, pressure can be adjusted. Furthermore, it gets more twisted the more pressure is applied. The same idea applies to the supply of water.
During the foam generator setup process, you can use construction pressure gauges to determine for yourself the precise pressure value that yields good foam. Furthermore, they will eloquently demonstrate the way in which pressure acts on the foam’s state.
A nozzle is integrated into the functional body. It is the conduit via which the concentrate of foam seeps into the pipe or foam gun containing filler, producing foam. It then enters the dispensing hose after going through the filter.
You must remember to seal all of the seams between the components when assembling the structure. Remember to carefully inspect each component for integrity and interoperability as well. The most frequent cause of the foam generator’s subpar performance is this assumption.
Step | Description |
1 | Gather materials: air compressor, foam gun, hose, foam solution |
2 | Connect the foam gun to the air compressor using the hose |
3 | Fill the foam gun with the foam solution |
4 | Adjust the air pressure on the compressor to control foam output |
5 | Test the foam generator to ensure even foam distribution |
Building your own construction foam generator is an enjoyable and economical project. If you have the right supplies and a little perseverance, you can make a tool that will help you save money and get high-quality foam for a variety of building applications.
Getting basic parts like a mixing chamber, a foam lance, and a compressor is part of the process. Assuring the generator is assembled accurately and safely requires that you follow the step-by-step instructions. To ensure that the apparatus generates the appropriate foam consistency, it is crucial to conduct extensive testing.
Building your own foam generator allows you to better understand how it functions and tailor it to your own needs. This do-it-yourself method improves your abilities and makes you feel like a success. It also makes room for more do-it-yourself projects in the future.
