[0002] Bentonite is a non-metallic mineral product with montmorillonite as a main mineral component, and the montmorillonite structure is a 2:1 type crystal structure composed of two silicon oxygen tetrahedrons and one aluminum oxygen octahedron. Some cations such as Cu, Mg, Na, K and the like exist in the layered structure formed by the montmorillonite cell. When the interlayer cation is Na+, the bentonite is called sodium-based bentonite; when the interlayer cation is Ca2+, the bentonite is called calcium-based bentonite; when the interlayer cation is H+, the bentonite is called hydrogen-based bentonite, and the bentonite plays an important role in various industries and environmental applications due to its special structure and adsorption performance.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0026] Please refer to Figure 1 - Figure 10The embodiment of the application is an automatic grinding device for bentonite powder crushing, which comprises a bottom plate 1, a machine shell 3 fixed on the top of the bottom plate 1 through a support, a grinding tank 2 fixed on the top of the bottom plate 1, a driving shaft 23 rotatably installed on the inner wall of the grinding tank 2, a crushing roller group 4 arranged in the machine shell 3, a spiral feeding assembly 31 arranged at the bottom of the machine shell 3, the outlet end of the spiral feeding assembly 31 being fixed on the outer wall of the grinding tank 2, the driving shaft 23 being driven by a motor, a grinding roller 22 fixed on the outer wall below the driving shaft 23, a grinding table 21 fixed on the inner wall of the grinding tank 2, a screening device 5 arranged at the machine shell 3 and the grinding tank 2, the screening device 5 comprising four L-shaped scrapers 51 fixed on the outer wall above the driving shaft 23, a wave-shaped ring groove disc 52 fixed between the top portions of the four L-shaped scrapers 51, four elastic extension rods two 59 fixed at the four corners of the inner wall of the machine shell 3, a back-shaped sliding frame 54 fixed between the bottom portions of the extension ends of the four elastic extension rods two 59, a plurality of cylinders 55 fixed in the inside of the back-shaped sliding frame 54, a sliding rod 53 transversely penetrating and slidingly installed between the machine shell 3 and the grinding tank 2, the L-shaped scrapers 51 being arranged to stir the bentonite raw materials entering the inside of the grinding tank 2, so that the bentonite raw materials are uniformly distributed on the grinding roller 22, the uniform distribution of the bentonite raw materials avoiding the excessive accumulation or density of the bentonite raw materials in some areas of the grinding roller 22, thereby reducing the risk of local excessive wear or blockage, improving the uniformity and efficiency of the grinding process, the wave-shaped ring groove disc 52 being provided with a wave-shaped ring groove on the top portion thereof, one end of the sliding rod 53 being slidingly installed in the wave-shaped ring groove of the wave-shaped ring groove disc 52, a plurality of round blocks two 57 being uniformly and equidistantly fixed on the other end of the sliding rod 53, a round block one 56 being fixed on the bottom of the cylinder 55 located in the middle, the bottom semicircular surface of the round block one 56 being located on the top semicircular surface movement track of the plurality of round blocks two 57, a plurality of elastic extension rods one 58 being uniformly and equidistantly fixed on the two sides of the other end of the sliding rod 53, the extension ends of the elastic extension rods one 58 penetrating the cylinder 55, a J-shaped plate 511 being fixed between the top portions of the adjacent two elastic extension rods one 58, larger bentonite raw materials being intercepted in the plurality of J-shaped plates 511 and the plurality of cylinders 55, smaller bentonite raw materials penetrating the plurality of cylinders 55, thereby realizing the screening operation of the crushed bentonite raw materials, the screening ensuring that the bentonite particle size entering the grinding tank 2 is relatively uniform, avoiding the large-particle bentonite raw materials entering the grinding link, thereby improving the grinding efficiency, the J-shaped plate 511 being composed of a vertical plate and an inverted square root-shaped plate, the vertical plate being fixed on the extension end top of the elastic extension rod one 58, the bottom of the vertical plate being in contact with the top of the back-shaped sliding frame 54, the inverted square root-shaped plate being fixed on the top of the vertical plate, an extrusion plate 512 being fixed on the outer wall below the J-shaped plate 511, a plurality of L-shaped inclined plates 510 being uniformly and equidistantly fixed on the top of the back-shaped sliding frame 54, the inverted square root-shaped plate of the J-shaped plate 511 being in contact with the top surface of the L-shaped inclined plate 510 adjacent to one side, and the like.The J-shaped plate 511 and the L-shaped inclined plate 510 adjacent to the other side leave a three-centimeter gap (as shown in Figure 9 The several cylinders 55 leave a two-centimeter gap between them. Through the above structure, the meandering carriage 54 drives the several cylinders 55 and the several J-shaped plates 511 to fluctuate up and down to screen the bentonite raw materials; each time the slide rod 53 moves horizontally towards the grinding tank 2, through the above structure, the J-shaped plate 511 drives the pressing plate 512 to press the bentonite raw materials between the L-shaped inclined plate 510 adjacent to the other side, and the inverted "√" shaped plate of the J-shaped plate 511 and the L-shaped inclined plate 510 adjacent to the other side press the bentonite raw materials intercepted by the J-shaped plate 511 (from Figure 9 to the state Figure 10 ), so as to achieve the purpose of crushing larger bentonite raw materials; when the slide rod 53 moves horizontally towards the casing 3, through the above structure, the J-shaped plate 511 will push the larger bentonite raw materials in the gap between the L-shaped inclined plate 510 adjacent to the other side away from the L-shaped inclined plate 510, and the larger bentonite raw materials will pass over the L-shaped inclined plate 510 and fall on the previous J-shaped plate 511 (from Figure 10 to the state Figure 9 ), so that the larger bentonite raw materials here can be crushed next time.

[0027] The extension ends of the two elastic extension rods 59 on one side are fixed with L-shaped frames 513 on the side close to each other, and the top of the two L-shaped frames 513 on one side is fixed with a triangular plate 515, and the top of the two L-shaped frames 513 on the other side is fixed with a triangular plate 514. The triangular plate 515 and the triangular plate 514 are used to block the gap between the two L-shaped inclined plates 510 on both sides and the inner wall of the casing 3. The triangular plate 515 and the triangular plate 514 are arranged to avoid the problem that the bentonite raw materials falling from the crushing roller group 4 fall into the gap between the two L-shaped inclined plates 510 on both sides and the casing 3.

[0028] In use, the bentonite raw materials are put into the shell 3, and the crushing roller group 4 crushes the bentonite raw materials. The crushed bentonite raw materials fall to the screw feeding assembly 31, which feeds the crushed bentonite into the grinding tank 2. The motor drives the driving shaft 23 to rotate, which drives the grinding roller 22 to rotate. The grinding roller 22 and the grinding table 21 cooperatively grind the bentonite fed into the grinding tank 2. In the process of the crushed bentonite raw materials falling to the screw feeding assembly 31, the crushed bentonite raw materials pass through the J-shaped plates 511 and then pass through the cylinders 55 (it should be noted that the distance between the cylinders 55 is two centimeters, and the distance between the J-shaped plates 511 and the adjacent L-shaped inclined plates 510 is three centimeters, so the particle size of the agglomerated bentonite intercepted at the J-shaped plates 511 is larger than that at the cylinders 55). The cylinders 55 and the J-shaped plates 511 screen the bentonite raw materials. The larger bentonite raw materials are intercepted at the J-shaped plates 511 and the cylinders 55, and the smaller bentonite raw materials pass through the cylinders 55, thereby realizing the screening of the crushed bentonite raw materials. Through screening, the particle size of the bentonite entering the grinding tank 2 is uniform, avoiding the entry of large-particle bentonite raw materials into the grinding link, which improves the efficiency of the grinding operation. During the rotation of the driving shaft 23, the L-shaped scraper 51 rotates, which stirs the bentonite raw materials entering the grinding tank 2, so that the bentonite raw materials are uniformly distributed at the grinding roller 22. Through uniform distribution of the bentonite raw materials, the risk of excessive accumulation or density of the bentonite raw materials in some areas of the grinding roller 22 is reduced, thereby improving the uniformity and efficiency of the grinding process.

[0029] In the process of rotating the L-shaped scraper 51, the L-shaped scraper 51 also drives the wave-shaped ring groove disc 52 to rotate, and the wave-shaped ring groove of the wave-shaped ring groove disc 52 pushes the sliding rod 53 to move reciprocatingly and transversely, and the sliding rod 53 drives the circular block two 57 to move reciprocatingly, and when the circular block two 57 moves to the position of the circular block one 56, the circular block two 57 pushes the circular block one 56 to drive the middle cylindrical body 55 to move upward, and the cylindrical body 55 drives the back-shaped sliding bracket 54 to extrude the stretching end of the elastic stretching rod two 59, and when the circular block two 57 no longer pushes the circular block one 56, under the elastic force of the elastic stretching rod two 59, the elastic stretching rod two 59 drives the back-shaped sliding bracket 54 and the cylindrical body 55 to reset and move downward, and the process is repeated, so that the back-shaped sliding bracket 54 drives a plurality of cylindrical bodies 55 and a plurality of J-shaped plates 511 to move up and down to perform the screening operation on the bentonite raw materials, and it should be noted that when the back-shaped sliding bracket 54 drives the J-shaped plate 511 to move upward, the J-shaped plate 511 pulls the stretching end of the elastic stretching rod one 58 to stretch upward; each time the sliding rod 53 moves transversely in the direction of the grinding tank 2, the sliding rod 53 drives the J-shaped plate 511 to move through the elastic stretching rod one 58, and the J-shaped plate 511 moves from the L-shaped inclined plate 510 adjacent to it to the L-shaped inclined plate 510 adjacent to the other side thereof (from the state of Figure 9 to the state of Figure 10 In this process, the J-shaped plate 511 drives the extrusion plate 512 to move close to the L-shaped inclined plate 510 adjacent to the other side, so that the extrusion plate 512 extrudes the bentonite raw materials between the L-shaped inclined plate 510 adjacent to the other side, and the inverted “√” shaped plate of the J-shaped plate 511 and the L-shaped inclined plate 510 adjacent to the other side extrude the bentonite raw materials intercepted by the J-shaped plate 511, so as to achieve the purpose of crushing the larger bentonite raw materials; in this process, the crushing roller group 4 continuously feeds the materials, and the J-shaped plate 511 and the L-shaped inclined plate 510 adjacent to the other side continuously intercept the larger bentonite raw materials, part of the bentonite raw materials falls between the J-shaped plate 511 and the L-shaped inclined plate 510 adjacent to it, the smaller bentonite raw materials pass through the gap between the J-shaped plate 511 and the L-shaped inclined plate 510 adjacent to it (the gap is equal to the gap between the plurality of cylindrical bodies 55), and the larger bentonite raw materials are intercepted there; when the sliding rod 53 moves transversely in the direction of the casing 3, the J-shaped plate 511 moves from the L-shaped inclined plate 510 adjacent to the other side to the L-shaped inclined plate 510 adjacent to it (from the state of Figure 10 to the state of Figure 9 At this time, the J-shaped plate 511 pushes the larger bentonite raw materials in the gap between the L-shaped inclined plate 510 adjacent to it away from the L-shaped inclined plate 510, and the larger bentonite raw materials pass over the L-shaped inclined plate 510 and fall on the previous J-shaped plate 511, so that the larger bentonite raw materials there can be crushed next time.

[0030] Meanwhile, the triangular plate two 515 and the triangular plate one 514 respectively form an obstruction above the gap between the two L-shaped inclined plates 510 on both sides and the inner wall of the shell 3, thereby avoiding the problem that the bentonite raw materials falling from the crushing roller group 4 fall into the gap between the two L-shaped inclined plates 510 and the shell 3. It should be noted that when the return-shaped slide 54 extrudes the telescopic end of the elastic telescopic rod two 59 each time, the telescopic end of the elastic telescopic rod two 59 telescopes upward, and the telescopic end of the elastic telescopic rod two 59 drives the triangular plate two 515 and the triangular plate one 514 to move upward through the L-shaped frame 513, respectively, so that the existence of the triangular plate two 515 and the triangular plate one 514 does not interfere with the operation of the J-shaped plate 511.

[0031] Please refer to Figure 1 Figure 10 On the basis of the above embodiment, in another embodiment of the present application, the shell 3 is provided with a heating assembly 6, and the heating assembly 6 comprises a heating machine 61 and a plurality of V-shaped heating plates 62. The heating machine 61 is fixed on the outer wall of the shell 3, and the plurality of V-shaped heating plates 62 are uniformly and equidistantly fixed at the bottom of the inverted “√” plate of the J-shaped plate 511. The V-shaped heating plates 62 are connected with the heating machine 61 through wires. Through the above structure, the heating machine 61 heats the V-shaped heating plates 62, and the V-shaped heating plates 62 heat the inverted “√” plate of the J-shaped plate 511, so that the J-shaped plate 511 heats the intercepted larger bentonite raw materials. The heating effect helps to evaporate the water in the bentonite raw materials, reduces the water content, and makes the particles of the bentonite more loose and the internal cohesive force weaker. Thus, the bentonite raw materials are crushed in the subsequent process, and the subsequent grinding operation is facilitated, thereby improving the crushing efficiency and the quality of the final product.

[0032] ​The J-shaped plate 511 is provided with a distribution device 7, which includes a plurality of diamond-shaped rollers 71, a plurality of friction wheels 72, and two friction plates 73 fixed between the outer walls of the opposite two elastic telescopic rods 59. The plurality of diamond-shaped rollers 71 are fixed on the top of the inverted "√" plate of the J-shaped plate 511 near one side of the pressing plate 512 through supports. The plurality of friction wheels 72 are fixed on both sides of the plurality of diamond-shaped rollers 71. The outer wall of the friction wheel 72 and the top of the friction plate 73 are both provided with rough surfaces. The outer wall of the friction wheel 72 is in contact with the top of the friction plate 73. When the J-shaped plate 511 moves each time, the above structure is set to make the diamond-shaped rollers 71 distribute the bentonite raw materials evenly on the J-shaped plate 511. This process ensures that the bentonite raw materials are evenly distributed on the surface of the J-shaped plate 511, avoiding the aggregation or uneven distribution of the bentonite raw materials. When the J-shaped plate 511 heats the bentonite raw materials later, the even distribution ensures that the bentonite can quickly and evenly absorb heat, while avoiding the aggregation of the bentonite raw materials, which causes smaller bentonite to be unable to pass through the J-shaped plate 511. At the same time, the rotation of the diamond-shaped rollers 71 can drive the bentonite raw materials intercepted at the J-shaped plate 511 to rotate, thereby enhancing the contact area of the bentonite raw materials with the heating surface of the J-shaped plate 511 and promoting the uniform transfer of heat.

[0033] In use, the heating machine 61 is started to heat the V-shaped heating plate 62, which heats the inverted "√" plate of the J-shaped plate 511, so that the J-shaped plate 511 heats the intercepted larger bentonite raw materials. The heating action helps to evaporate the water in the bentonite raw materials, reduces the water content, and makes the particles of bentonite more loose and the internal cohesive force weaker, which facilitates the crushing of the bentonite raw materials later and helps the subsequent grinding operation, improving the crushing efficiency and the quality of the final product.

[0034] When the J-shaped plate 511 moves each time, the J-shaped plate 511 drives the diamond-shaped rollers 71 to move, and the diamond-shaped rollers 71 drive the friction wheels 72 to move. Under the action of the friction between the friction wheel 72 and the friction plate 73, the friction plate 73 drives the diamond-shaped rollers 71 to rotate through the friction wheel 72. The rotation of the diamond-shaped rollers 71 helps to evenly distribute the bentonite raw materials on the J-shaped plate 511. This process ensures that the bentonite raw materials are evenly distributed on the surface of the J-shaped plate 511, avoiding the aggregation or uneven distribution of the bentonite raw materials. When the J-shaped plate 511 heats the bentonite raw materials later, the even distribution ensures that the bentonite can quickly and evenly absorb heat, while avoiding the aggregation of the bentonite raw materials, which causes smaller bentonite to be unable to pass through the J-shaped plate 511.
