Description

Technical Field

[0001] The present invention relates to the technical field of building production equipment, and specifically to a slurry mixing and stirring device for the middle layer of autoclaved aerated concrete slabs. Background Art

[0002] The raw materials for the middle layer slurry of autoclaved aerated concrete slabs refer to a new type of wall material made by using fly ash, coal cinder, coal gangue, tailings slag, chemical slag, or natural sand, sea mud, etc. (one or several of the above raw materials) as the main raw materials and using cement as a setting agent without high-temperature calcination, which is called the middle layer slurry of autoclaved aerated concrete slabs. In the prior art, if the raw materials for the middle layer slurry of autoclaved aerated concrete slabs are not properly crushed before stirring, it may lead to uneven particle sizes of the materials, uneven mixing between large particles and small particles, which will affect the texture and performance of the stirred materials, thus affecting the quality and performance of the final product. At the same time, there is a lack of intercepting the large particles of the uncrushed raw materials and crushing them again.

[0003] For example, an intelligent stirring device for raw materials for the preparation of autoclaved aerated concrete disclosed in the authorized patent document with the application number CN202311326780.4 includes a stirring tank and support feet. A top shell is fixedly installed at the top of the stirring tank. A feeding door is installed on the front surface of the stirring tank, and a perspective window is opened on the surface of the feeding door. An air inlet is provided on the right top surface of the stirring tank. Through the design of setting two driving gear columns, after gas is charged into the stirring tank, when the adjustment knob is on the left side, the internal rotating frame can be driven by the left gear column and stirred, and when the adjustment knob is on the right side, it will disconnect from the left gear column in the inflated state. However, when there is no gas in the stirring tank and the adjustment knob is on the left side, the stirring frame does not rotate, and at this time, when the adjustment knob is on the right side, the stirring frame rotates. Through this design, it is possible to intelligently and conveniently control whether to select pressurized stirring for the raw materials for concrete preparation in the stirring tank.

[0004] The above patent has the problem that if the raw materials for the middle layer slurry of autoclaved aerated concrete slabs are not properly crushed before stirring, it may lead to uneven particle sizes of the materials, uneven mixing between large particles and small particles, which will affect the texture and performance of the stirred materials. Therefore, we need to provide a slurry mixing and stirring device for the middle layer of autoclaved aerated concrete slabs. Summary of the Invention

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-7 , the present invention provides a technical solution: a slurry stirring device for the middle layer of autoclaved aerated concrete slabs, including:

[0032] a treatment bin 1 and a mixing bin 2 provided at the bottom of the mixing bin 2;

[0033] Inside the treatment bin 1, there is a crushing treatment mechanism 3 for crushing the raw materials of the middle layer slurry of autoclaved aerated concrete slabs;

[0034] On one side of the treatment bin 1, there is a material conveying mechanism 4 for secondary crushing of large particle raw materials;

[0035] Inside the mixing bin 2, there is a material mixing mechanism 5 for mixing and stirring the raw materials of the middle layer slurry of autoclaved aerated concrete slabs;

[0036] Specifically, a crushing mechanism 3 is arranged in the processing bin 1 to crush the slurry raw materials in the middle layer of the autoclaved aerated concrete slab. The size of the raw materials after crushing is more uniform, which helps to achieve a more uniform mixing during the slurry mixing process. The crushing treatment helps the foaming agent to be evenly distributed in the raw materials, thereby improving the foaming effect. Uniform foaming can form a more regular and dense pore structure, further improving the performance of the autoclaved aerated concrete slab.

[0037] The crushing mechanism 3 includes two cylinders 31 rotatably installed in the processing bin 1. Grinding tooth groups 32 are integrally processed on the surfaces of the two cylinders 31. The two grinding tooth groups 32 are meshed with each other. Slots 33 are opened at one ends of the two cylinders 31. A driving member 30 for synchronously rotating the two cylinders 31 is arranged on one side of the processing bin 1. Gears 16 are fixedly installed at one ends of the two cylinders 31, and the two gears 16 are meshed with each other;

[0038] In this embodiment, the driver 301 is started to drive the output rod 302 to rotate, and the output rod 302 is inserted into the slot 33, thereby driving the cylinder 31 to rotate. Gears 16 are arranged at one ends of the two cylinders 31, and the two gears 16 are meshed with each other. When one cylinder 31 rotates, it drives the other cylinder 31 to rotate, and the grinding tooth group 32 on the surface of the cylinder 31 rotates. The slurry raw materials in the middle layer of the autoclaved aerated concrete slab are all poured into the processing bin 1 through the feed hopper 9 to crush the raw materials. Auxiliary tooth groups 17 are fixedly installed on both sides of the inner wall of the processing bin 1. The auxiliary tooth groups 17 are used in cooperation with the grinding tooth groups 32 to assist in crushing the raw materials. The crushed raw materials enter the processing bin 1. The large-particle raw materials are intercepted by the filter plate 6. Since the filter plate 6 is inclined, the large-particle raw materials enter the recycling frame 8 through the discharge port 7;

Through heating, it can ensure that the materials in the mixing tank reach the appropriate reaction temperature, thereby promoting more sufficient reaction and mixing. This helps to improve the strength and pore structure uniformity of the autoclaved aerated concrete slab, thereby improving the product quality. Heating can reduce the viscosity of the materials, making them easier to stir and mix. This helps to reduce the energy consumption during the stirring process and improve the stirring efficiency. At the same time, heating can also promote the uniform distribution of the materials in the mixing tank, avoiding the situation of local over-concentration or over-dilution;

Through heating, it can ensure that the materials in the mixing tank reach the appropriate reaction temperature, thereby promoting more sufficient reaction and mixing. This helps to improve the strength and pore structure uniformity of the autoclaved aerated concrete board, thereby improving the product quality. Heating can reduce the viscosity of the materials, making them easier to stir and mix. This helps to reduce the energy consumption during the stirring process and improve the stirring efficiency.
