Description

Technical Field

[0001] This utility model relates to the field of foamed concrete technology, and in particular to an integrated device for preparing slag slurry foamed concrete. Background Technology

[0002] Foamed concrete is a lightweight, thermally insulating material that can be used for backfilling in projects such as abutments and embankment slopes. However, in backfilling projects such as pipe trenches, drainage trenches, karst caves, and roadbeds, where the strength requirements for foamed concrete are not high, it can be replaced with a mixture of slag and mud, which not only reduces environmental pollution but also lowers costs. However, traditional foamed concrete preparation equipment can only mix cement slurry and foam. Because viscous slag tends to clump, and mud contains impurities such as sand and gravel, it cannot be used directly.

[0003] In summary, for this new material, slag slurry foamed concrete, there is still a lack of equipment that can produce slag slurry foamed concrete with stable quality, high production efficiency, and integrated processes such as raw material processing, foaming, mixing, and molding. Research and development is urgently needed to meet market demands. Utility Model Content

The air compressor 6 and the check valve 401 work together to prevent the foam pipe 401 from being blocked, and provide a guarantee for improving the mixing effect of foam and slurry; the purpose of injecting high-pressure foam at the bottom of the mixing chamber 301 is to solve the problem that the foam is easy to float on the top of the slurry during mixing, causing a difference in the mixing effect, and improves the mixing effect of foam and slurry; a moisture meter 303 is installed on the inner side wall of the mixing chamber 301. The moisture meter 303 is an infrared moisture meter. Its principle is mainly based on infrared spectroscopy technology. It determines the moisture content by measuring the absorption or reflection of infrared light of a specific wavelength by the substance.

[0023] like Figure 1 As shown, the crusher 1, vibrating screen 2, mixer 3, foaming machine 4, and air compressor 6 are connected to a power source 5 via wires 501, and each component also has an independent switch. The mixer 3 is placed in the space formed by the columns, and the foaming machine 4 and air compressor 6 are located on the side of the mixer 3.

[0024] like Figure 2As shown, a roller 103 is rotatably connected inside the hopper 102. The roller 103 has several protrusions, which are triangular protrusions, for crushing slag. The roller 103 is connected to a drive shaft 104, with both ends of the drive shaft 104 extending out of the roller 103. One end of the roller 103 is connected to a first motor 101 through the drive shaft 104. The bottom of the first motor 101 is fixed to the support column 106 through a support plate 105. The other end of the roller 103 is connected to the rotation groove 107 on the side wall of the support column 106 through the drive shaft 104.

One end of the rotating shaft 307 is connected to a third motor 302, which is fixed on the base. The other end of the rotating shaft 307 extends into the drum on the support frame 306. The rotating shaft 307 and the support frame 306 are rotatably connected.

[0027] like Figure 1-5 As shown, the method of using this integrated equipment for preparing slag slurry foamed concrete is as follows:

[0028] Step 1, Material Processing: When the material used is mud, directly turn on the second motor 203 switch of vibrating screen 2 to pump the mud into vibrating screen 2. The gravel in the mud will remain on screen 204. After the gravel is cleaned off, the high-quality mud will flow into mixer 3. When the material used is slag, turn on the first motor 101 of crusher 1 and the second motor 203 switch of vibrating screen 2 to pour the slag blocks into crusher 1 from feed port 1021 for crushing. The crushed slag powder will fall from discharge port 1022 onto screen 204 of vibrating screen 2. Large slag particles will remain on screen 204 for continued recycling. High-quality slag particles will eventually fall into mixer 3.

[0029] Step 2, Foaming: Open foaming machine 4, inject YS-500 animal protein physical foaming agent into it, and dilute it with water to prepare stable and delicate foam.

[0030] Step 3, Mixing and Molding: Turn on the third motor 302 switch of mixer 3, add water or mud to the slag from step 1 and mix into a paste-like slurry. Turn on the moisture meter 303 to determine the moisture content of the paste-like slurry. The moisture content data at this time will provide a reference for the amount of water and cement to be added later. Add cement and water to mixer 3 and mix evenly with the paste-like slurry. During the mixing process of the above materials, open the check valve 402. The foam prepared in foaming machine 4 flows into mixer 3 through foam pipe 401. After all materials are mixed evenly, slag slurry foam concrete is formed.
