Description

Technical Field

[0001] This utility model relates to the field of standard brick preparation technology, specifically to a mixing device for raw materials in standard brick preparation. Background Technology

[0002] Standard brick preparation refers to the process of processing basic materials (such as clay, shale, fly ash, etc.) into building bricks that meet national standards through processes such as raw material processing, mixing, molding, drying and firing. Its core steps include removing impurities from raw materials, wetting, mixing and molding, which directly affect the strength, durability and appearance quality of the product.

[0003] In the preparation of aerated concrete bricks, a mixing device ensures that raw materials (such as clay, additives, water, etc.) are fully mixed, eliminating lumps or stratification, and providing a homogeneous slurry for subsequent molding. However, because powdery materials (such as cement and fly ash) have fine particles, they are easily suspended during mixing due to airflow disturbances or mechanical action, causing dust diffusion and pollution to the surrounding environment. Existing technology (Chinese patent application CN202321272468.7, filed on 2023-05-24) discloses a uniform mixing device for aerated concrete brick raw materials. During use, it includes a mixing chamber, inside which a first stirring shaft and a second stirring shaft are rotatably connected. The shaft, through the cooperation of the mixing box, motor, rotating shaft, first sprocket, first stirring shaft, second stirring shaft, spiral stirring blades, transmission chain, second sprocket, pulley and transmission belt, enables the three spiral stirring blades to rotate inside the mixing box, thereby mixing the raw materials of the aerated concrete blocks in the mixing box from top to bottom. The stirring blades, in conjunction with the mixing, make the raw materials more thoroughly mixed and of better quality. Through the cooperation of the cylinder, connecting seat, first hinge seat, rotating rod, guide rod, sliding block, second hinge seat, connecting rod and top plate, the top plate knocks on the material box, which is more effective in preventing material accumulation.

[0004] Although existing technologies can improve the mixing efficiency of raw materials, there are still some shortcomings in the working process. When mixing the raw materials for standard brick preparation, dust will be stirred up, causing pollution to the surrounding environment. Utility Model Content

[0005] The purpose of this utility model is to provide a mixing device for raw materials used in the preparation of standard bricks, so as to solve the problem mentioned in the background art that dust is raised and pollutes the surrounding environment when mixing raw materials for the preparation of standard bricks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for raw materials used in the preparation of standard bricks, comprising a shell, a cover on the top of the shell, a mixing tank rotatably connected to the inner wall of the shell, an integrated mixing and dust extraction component on the top of the cover, the integrated mixing and dust extraction component acting on the mixing tank to achieve mixing and dust extraction inside the mixing tank, and a linkage rotation component on one side of the cover, the linkage rotation component acting on the mixing tank to achieve rotation of the mixing tank.

[0011] As a preferred technical solution of this application, the outer wall of the second rotating rod is rotatably connected to a support block, and the support block is fixedly connected to the cover.

[0012] As a preferred technical solution of this application, the bottom surface of the cover is provided with a sealing block, the sealing block is annular in shape, and the external dimensions of the sealing block are consistent with the internal dimensions of the sealing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This raw material mixing device for aerated concrete block preparation adopts a composite motion mechanism of stirring, dust collection, and tank rotation, which effectively solves the problems of dust pollution and mixing efficiency during the mixing process of aerated concrete block raw materials. Through the synchronous rotation design of the hollow rotating rod and the dust collection port, combined with the negative pressure generated by the centrifugal fan, real-time dynamic collection of dust during the stirring process is realized. Furthermore, the cooperation between the annular sealing block and the sealing groove suppresses dust leakage, significantly reducing environmental pollution. Moreover, the composite motion mechanism of internal stirring and external rotation can form multi-dimensional flow in the mixing tank, avoiding the mixing dead zones of traditional stirring, and effectively improving the stirring efficiency. The specific details are as follows: 1. During use, the connection port is equipped with a collection device and a centrifugal fan. The motor drives the stirring rod to mix the raw materials through the first gear, the second gear, and the first rotating rod. The hollow first rotating rod serves as a dust suction channel and rotates synchronously during the mixing process. The centrifugal fan generates negative pressure, and the dust suction port draws the dust into the interior of the first rotating rod. The dust is then sucked into the collection device through the rotary joint and the connection port. This effectively solves the problem of dust being raised during the mixing of standard brick raw materials, reduces environmental pollution, and achieves clean production in the aerated concrete block preparation process.

[0014] 2. While the first rotating rod drives the stirring rod to stir the material in the mixing tank, the first rotating rod drives the second rotating rod and the third gear to rotate through the first sprocket, chain and second sprocket. The third gear meshes with the toothed track on the outer wall of the mixing tank, thereby driving the mixing tank to rotate. The combined motion of internal stirring and external rotation can effectively improve the mixing uniformity, realize the all-round mixing of materials, and effectively improve the mixing efficiency of raw materials for standard brick preparation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-6 The present invention provides the following technical solution: a mixing device for raw materials used in the preparation of standard bricks.

[0019] Example 1: To address the issue of dust being stirred up and polluting the surrounding environment during the mixing of raw materials for standard brick preparation, please refer to... Figures 1-5 The system includes a housing 1, a cover 2 on top of the housing 1, a mixing tank 5 rotatably connected to the inner wall of the housing 1, a mixing and dust extraction integrated assembly 3 on top of the cover 2, and a linkage rotation assembly 4 on one side of the cover 2. Figure 5 As shown, the integrated stirring and dust extraction assembly 3 includes a motor 301 fixedly connected to the top surface of the cover 2. A first gear 302 is fixedly connected to the output end of the motor 301. A second gear 303 is meshed with the outer wall of the first gear 302. A first rotating rod 304 is fixedly connected to the inner wall of the second gear 303. A stirring rod 306 is fixedly connected to the bottom end of the first rotating rod 304. Figure 5 As shown, the first rotating rod 304 is hollow, and dust suction ports 305 are fixedly connected to both sides of the outer wall of the first rotating rod 304. A rotary joint is rotatably connected to the top of the first rotating rod 304, and a connection port 307 is fixedly connected to the top surface of the rotary joint. Figure 5 As shown, a sealing block 8 is provided on the bottom surface of the cover 2. The sealing block 8 is ring-shaped, and the external dimensions of the sealing block 8 are consistent with the internal dimensions of the sealing groove 7.

[0020] During use, a collection device and a centrifugal fan are connected to the connection port 307. The motor 301 drives the first gear 302 to rotate. The meshing of the first gear 302 and the second gear 303 drives the first rotating rod 304 to rotate, thereby driving the stirring rod 306 to mix the raw materials. At the same time, the hollow first rotating rod 304 serves as a dust suction channel. The dust suction ports 305 on both sides rotate synchronously during the stirring process. The centrifugal fan generates negative pressure, which sucks the raised dust into the interior of the first rotating rod 304. The dust is then sucked into the collection device through the rotary joint and the connection port 307. This effectively solves the problem of dust being raised during the mixing of the standard brick raw materials. In addition, the annular sealing block 8 at the bottom of the cover 2 cooperates with the sealing groove 7 of the shell 1 to prevent dust leakage, suppress dust diffusion, reduce environmental pollution, and achieve clean production in the aerated concrete block preparation process.

[0021] Example 2: Figures 1-4 and Figure 6 The technical solution shown includes a toothed rail 6 on the outer wall of the mixing tank 5, the toothed rail 6 being annular in shape, and a sealing groove 7 on the top surface of the mixing tank 5, the sealing groove 7 being annular in shape. Figure 6 As shown, the linkage rotation assembly 4 includes a first sprocket 401 fixedly connected to the outer wall of the first rotating rod 304. One end of a chain 402 is meshed with the outer wall of the first sprocket 401, and the other end of the chain 402 is meshed with a second sprocket 403. The inner wall of the second sprocket 403 is fixedly connected to the second rotating rod 404, and a third gear 405 is fixedly connected to the bottom of the second rotating rod 404. Figure 6 As shown, a support block is rotatably connected to the outer wall of the second rotating rod 404, and the support block is fixedly connected to the cover 2.

[0022] In operation, when motor 301 drives the first rotating rod 304 and stirring rod 306 to rotate, simultaneously stirring the material inside the mixing tank 5, the first rotating rod 304 transmits power to the second rotating rod 404 and the third gear 405 via the first sprocket 401, chain 402, and second sprocket 403. This drives the third gear 405 to rotate, and the third gear 405 meshes with the gear rail 6 on the outer wall of the mixing tank 5, thereby driving the mixing tank 5 to rotate. This combined motion of internal stirring and external rotation effectively improves mixing uniformity, achieving all-around mixing of the material and effectively increasing the mixing efficiency of the raw materials for standard brick preparation. The above is the entire working process of the device, and the contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
