Description

Technical Field

[0001] This invention relates to the field of bentonite processing technology, specifically to an automatic grinding device for bentonite crushing and processing. Background Technology

[0002] Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. Montmorillonite has a 2:1 crystal structure consisting of two silicon-oxygen tetrahedra sandwiching a layer of aluminum-oxygen octahedra. Due to the layered structure formed by the montmorillonite unit cells, certain cations exist, such as Cu, Mg, Na, and K. When the interlayer cation is Na+, it is called sodium-based bentonite; when the interlayer cation is Ca2+, it is called calcium-based bentonite; and when the interlayer cation is H+, it is called hydrogen-based bentonite, etc. Because of its unique structure and adsorption properties, bentonite plays an important role in various industrial and environmental applications. After being mined from the raw ore, bentonite often needs to be crushed and then ground.

[0003] Chinese patent CN216093986U discloses a bentonite crushing and grinding device, including a base plate and a support frame. The support frame is located on the side wall of the base plate, and a crushing device is provided on the upper side wall of the support frame. A grinding device is also provided on the upper side wall of the base plate. The grinding device includes a grinding chamber, and a lifting mechanism is provided on the upper side wall of the grinding chamber. A grinding motor is provided in the lifting mechanism. A rotating shaft is connected to the shaft end of the grinding motor. The lower end of the rotating shaft passes through the upper side wall of the grinding chamber and is connected to a cylindrical grinding stone. A grinding body that fits with the grinding stone is fixedly connected to the inner wall of the grinding chamber. The advantage of this patent compared with the prior art is that the vertical height of the grinding stone can be adjusted by providing power through a cylinder, so as to select annular platforms with different internal through hole diameters for grinding, thereby grinding bentonite with various particle sizes.

[0004] However, the current grinding device has the following problems: when grinding bentonite, it is not convenient to screen the crushed bentonite raw material. Furthermore, when the bentonite raw material has a high moisture content, the crushed bentonite is prone to agglomeration, which increases the difficulty of subsequent grinding processing. Therefore, we propose an automatic grinding device for bentonite crushing and processing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic grinding device for bentonite crushing and processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic grinding device for bentonite crushing and processing, comprising a base plate, a housing fixed to the top of the base plate by a bracket, a grinding tank fixed to the top of the base plate, a drive shaft rotatably mounted on the top of the inner wall of the grinding tank, a crushing roller assembly disposed inside the housing, a spiral feeding assembly disposed at the bottom of the housing, the discharge end of the spiral feeding assembly fixed to the outer wall of the grinding tank, the drive shaft being driven by a motor, a grinding roller fixed to the lower outer wall of the drive shaft, a grinding table fixed to the inner wall of the grinding tank, and a screening device disposed at the housing and the grinding tank, the screening device comprising a solid... Four L-shaped scrapers are fixed on the outer wall above the drive shaft. During the rotation of the drive shaft, the L-shaped scrapers rotate, agitating the bentonite raw material entering the grinding tank. A wavy annular grooved disc is fixed between the tops of the four L-shaped scrapers. Four elastic telescopic rods are fixed at the four corners of the inner wall of the machine casing. A U-shaped slide is fixed between the bottom of the telescopic ends of the four elastic telescopic rods. Several cylinders are fixed inside the U-shaped slide. A slide rod is horizontally inserted and slidably installed between the machine casing and the grinding tank. The top of the wavy annular grooved disc has a wavy annular groove. One end of the slide rod is slidably installed inside the wavy annular groove of the wavy annular grooved disc, and the other end of the slide rod is... A plurality of circular blocks 2 are evenly and equidistantly fixed in the middle of the cylinder. A circular block 1 is fixed at the bottom of the cylinder in the middle. The bottom semicircular surface of the circular block 1 is located on the movement trajectory of the top semicircular surfaces of the plurality of circular blocks 2. A plurality of elastic telescopic rods 1 are evenly and equidistantly fixed on both sides of the other end of the sliding rod. The telescopic ends of the elastic telescopic rods 1 pass through the cylinder. A J-shaped plate is fixed between the tops of two adjacent elastic telescopic rods 1. During the process of the crushed bentonite raw material falling into the screw feeding assembly, the crushed bentonite raw material will pass through several J-shaped plates, and then through several cylinders. The cylinders and the J-shaped plates will screen the bentonite raw material, and larger pieces of bentonite raw material will be separated into different sections. The material is trapped at several J-shaped plates and several cylinders, while smaller pieces of bentonite raw material pass through the cylinders, thus achieving the screening operation of the crushed bentonite raw material. The J-shaped plates consist of a vertical plate and an inverted "√" shaped plate. The vertical plate is fixed to the top of the telescopic end of the elastic telescopic rod, and the bottom of the vertical plate contacts the top of the U-shaped slide. The inverted "√" shaped plate is fixed to the top of the vertical plate. A pressing plate is fixed to the lower outer wall of the J-shaped plate. Several L-shaped inclined plates are evenly and equidistantly fixed to the top of the U-shaped slide. The inverted "√" shaped plate of the J-shaped plate contacts the top surface of the adjacent L-shaped inclined plate on one side, and a three-centimeter gap is left between the J-shaped plate and the adjacent L-shaped inclined plate on the other side (e.g., ...). Figure 9As shown), a two-centimeter gap is left between several of the cylinders. During the rotation of the L-shaped scraper, the L-shaped scraper also drives the wavy annular groove disk to rotate. The wavy annular groove of the wavy annular groove disk pushes the slide rod to move back and forth laterally. The slide rod drives the second round block to move back and forth. When the second round block moves to the position of the first round block, the second round block pushes the first round block, which drives the central cylinder upward. The cylinder drives the loop slide to squeeze the extension end of the elastic telescopic rod two. When the second round block no longer pushes the first round block, under the elastic force of the elastic telescopic rod two, the elastic telescopic rod two drives the loop slide and the cylinder to reset and move downward. Each time the slide rod moves laterally towards the grinding tank, the slide rod drives the J-shaped plate to move along with it through the elastic telescopic rod one. The J-shaped plate moves from the adjacent L-shaped inclined plate to the L-shaped inclined plate on the other side (from... Figure 9 The state becomes Figure 10 During this process, the J-shaped plate will drive the extrusion plate to move towards the adjacent L-shaped inclined plate on the other side, thereby causing the extrusion plate to squeeze the bentonite material between itself and the adjacent L-shaped inclined plate on the other side. The inverted "√" shaped plate of the J-shaped plate and the adjacent L-shaped inclined plate on the other side will squeeze the bentonite material intercepted by the J-shaped plate. During this process, when the crushing roller group continuously feeds material, the J-shaped plate and the adjacent L-shaped inclined plate on the other side will continuously intercept the larger bentonite material. Some of the bentonite material will fall between the J-shaped plate and its adjacent L-shaped inclined plate, smaller bentonite material will pass through the gap between the J-shaped plate and its adjacent L-shaped inclined plate, and larger bentonite material will be trapped here. When the slide bar moves laterally towards the machine casing, the J-shaped plate moves from the adjacent L-shaped inclined plate on the other side to its adjacent L-shaped inclined plate (from... Figure 10 The state becomes Figure 9 In this state, the J-shaped plate will push the larger bentonite material in the gap between it and the adjacent L-shaped inclined plate away from the L-shaped inclined plate. The larger bentonite material crosses the L-shaped inclined plate and falls on the previous J-shaped plate.

[0007] According to the above technical solution, an L-shaped frame is fixed on the side where the telescopic ends of the two elastic telescopic rods are close to each other. A triangular plate is fixed between the tops of the two L-shaped frames on one side, and a triangular plate is fixed between the tops of the two L-shaped frames on the other side. Both the triangular plate and the triangular plate are used to block the gap between the two L-shaped inclined plates on both sides and the inner wall of the casing.

[0008] According to the above technical solution, a heating assembly is provided at the casing. The heating assembly includes a heating machine and several V-shaped heating plates. The heating machine is fixed on the outer wall of the casing. The several V-shaped heating plates are evenly and equidistantly fixed at the bottom of the inverted "√" shaped plate of the J-shaped plate. The V-shaped heating plates are connected to the heating machine through wires. The heating machine heats the V-shaped heating plates, and the V-shaped heating plates heat the inverted "√" shaped plate of the J-shaped plate, thereby enabling the J-shaped plate to heat the larger bentonite raw material intercepted.

[0009] According to the above technical solution, a distribution device is provided at the J-shaped plate. The distribution device includes several diamond-shaped rollers, several friction wheels, and two friction plates. The two friction plates are respectively fixed between the outer walls of the telescopic ends of two opposing elastic telescopic rods. The several diamond-shaped rollers are respectively fixed to the top of the inverted "√" shaped plate of the J-shaped plate near the extrusion plate by brackets. The several friction wheels are respectively fixed on both sides of the several diamond-shaped rollers. The outer walls of the friction wheels and the tops of the friction plates are both rough surfaces. The outer walls of the friction wheels are in contact with the tops of the friction plates. Each time the J-shaped plate moves, the J-shaped plate will drive the diamond-shaped rollers to move, and the diamond-shaped rollers will drive the friction wheels to move. Under the action of friction between the friction wheels and the friction plates, the friction plates drive the diamond-shaped rollers to rotate through the friction wheels. The rotation of the diamond-shaped rollers helps to evenly distribute the bentonite raw material onto the J-shaped plate.

[0010] This invention provides an automatic grinding device for bentonite crushing and processing. It has the following beneficial effects: (1) The present invention uses a screening device to screen the bentonite raw material by means of several cylinders and several J-shaped plates. Through screening, the bentonite particles entering the grinding tank are made more uniform in size, and large particles of bentonite raw material are prevented from entering the grinding process, thus improving the efficiency of the grinding operation. At the same time, the drive shaft and L-shaped scraper work together to turn the bentonite raw material into the grinding tank, so that the bentonite raw material is evenly distributed at the grinding roller. By evenly distributing the bentonite raw material, excessive accumulation or density of bentonite raw material in certain areas of the grinding roller is avoided, thereby reducing the risk of local excessive wear or blockage and improving the uniformity and efficiency of the grinding process. At the same time, the L-shaped scraper, the wave-shaped annular groove, the slide bar, the second round block, and the first round block work together to make the loop slide drive several cylinders and several J-shaped plates to screen the bentonite raw material in a wave-like manner. Each time the slide bar moves laterally towards the grinding tank, the slide bar, the first elastic telescopic rod, the J-shaped plate, and the L-shaped inclined plate work together to screen the bentonite raw material. The J-shaped plate, in conjunction with the extrusion plate, crushes the bentonite material between itself and the adjacent L-shaped inclined plate on the other side. Meanwhile, the inverted "√" shaped plate of the J-shaped plate, along with the adjacent L-shaped inclined plate on the other side, crushes the bentonite material intercepted by the J-shaped plate, thus crushing larger pieces of bentonite. Simultaneously, the J-shaped plate and the adjacent L-shaped inclined plate continuously intercept larger pieces of bentonite, with some falling between the J-shaped plate and its adjacent L-shaped inclined plate. Smaller pieces of bentonite pass through the gap between the J-shaped plate and its adjacent L-shaped inclined plate, while larger pieces are retained there. When the slide bar moves laterally towards the machine casing, the J-shaped plate moves from the adjacent L-shaped inclined plate to its adjacent L-shaped inclined plate. At this point, the J-shaped plate pushes the larger pieces of bentonite in the gap between its adjacent L-shaped inclined plate away from the L-shaped inclined plate. The larger pieces of bentonite then cross the L-shaped inclined plate and fall onto the previous J-shaped plate, allowing them to be crushed again in the next operation.

[0011] (2) The present invention, through the setting of the heating component, enables the heating machine to heat the V-shaped heating plate, which in turn heats the inverted "√" shaped plate of the J-shaped plate, thereby enabling the J-shaped plate to heat the larger bentonite raw material intercepted. The heating effect helps to evaporate the moisture in the bentonite raw material, reduce its water content, make the bentonite particles looser, and weaken the internal cohesion. This makes it easier for the bentonite raw material to be crushed in the subsequent process, and also helps to carry out the subsequent grinding operation, thereby improving the crushing efficiency and the quality of the final product.

[0012] (3) The present invention, through the setting of the distribution device, enables the J-shaped plate, the diamond roller, the friction wheel, and the friction plate to drive the diamond roller to rotate. The rotation of the diamond roller helps to evenly distribute the bentonite raw material onto the J-shaped plate. This process ensures that the bentonite raw material is evenly distributed on the surface of the J-shaped plate, avoiding the aggregation or uneven distribution of the bentonite raw material. When the J-shaped plate heats the bentonite raw material, the even distribution ensures that the bentonite can absorb heat quickly and evenly, while avoiding the aggregation of the bentonite raw material, which would prevent smaller bentonite from passing through the J-shaped plate. At the same time, the rotation of the diamond roller can drive the bentonite raw material intercepted at the J-shaped plate to rotate, thereby increasing the contact area between the bentonite raw material and the heating surface of the J-shaped plate and promoting the uniform transfer of heat.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] Please see Figure 1 - Figure 10One embodiment of the present invention is as follows: an automatic grinding device for bentonite crushing and processing includes a base plate 1, a housing 3 fixed to the top of the base plate 1 by a bracket, a grinding tank 2 fixed to the top of the base plate 1, a drive shaft 23 rotatably mounted on the top of the inner wall of the grinding tank 2, a crushing roller assembly 4 disposed inside the housing 3, a spiral feeding assembly 31 disposed at the bottom of the housing 3, the discharge end of the spiral feeding assembly 31 fixed to the outer wall of the grinding tank 2, the drive shaft 23 being driven by a motor, a grinding roller 22 fixed to the lower outer wall of the drive shaft 23, a grinding table 21 fixed to the inner wall of the grinding tank 2, and a screening device 5 disposed at the housing 3 and the grinding tank 2. The screening device 5 includes four L-shaped scrapers 51 fixed to the upper outer wall of the drive shaft 23, and four L-shaped scrapers 51 fixed to the outer wall of the drive shaft 23. The structure consists of a wavy annular groove 52 at the top, four elastic telescopic rods 59 fixed at the four corners of the inner wall of the housing 3, a U-shaped slide 54 fixed between the bottom of the telescopic ends of the four elastic telescopic rods 59, several cylinders 55 fixed inside the U-shaped slide 54, and a slide rod 53 that runs horizontally through and slides between the housing 3 and the grinding tank 2. This structure allows the L-shaped scraper 51 to agitate the bentonite material entering the grinding tank 2, ensuring that the bentonite material is evenly distributed on the grinding roller 22. This even distribution of the bentonite material prevents excessive accumulation or density in certain areas of the grinding roller 22, reducing the risk of localized excessive wear or blockage, and improving the uniformity and efficiency of the grinding process. The wavy annular groove 52... The top of the tray 52 has a wavy annular groove. One end of the slide rod 53 is slidably installed inside the wavy annular groove of the tray 52. ​​Several circular blocks 57 are evenly and equidistantly fixed at the top of the other end of the slide rod 53. A circular block 56 is fixed at the bottom of the central cylinder 55. The bottom semicircular surface of the circular block 56 lies on the movement trajectory of the top semicircular surfaces of the several circular blocks 57. Several elastic telescopic rods 58 are evenly and equidistantly fixed on both sides of the other end of the slide rod 53. The telescopic ends of the elastic telescopic rods 58 pass through the cylinder 55. A J-shaped plate 511 is fixed between the tops of two adjacent elastic telescopic rods 58. Through this structure, larger bentonite raw materials are respectively intercepted at several J-shaped plates 511 and several cylinders 55, while smaller ones... The bentonite raw material passes through several cylinders 55, thereby achieving the screening operation of the crushed bentonite raw material. Through screening, it is ensured that the bentonite particle size entering the grinding tank 2 is relatively uniform, avoiding large particles of bentonite raw material from entering the grinding stage. This can improve the efficiency of the grinding operation. The J-shaped plate 511 is composed of a vertical plate and an inverted "√" shaped plate. The vertical plate is fixed to the top of the telescopic end of the elastic telescopic rod 58. The bottom of the vertical plate is in contact with the top of the U-shaped slide 54. The inverted "√" shaped plate is fixed to the top of the vertical plate. An extrusion plate 512 is fixed to the lower outer wall of the J-shaped plate 511. Several L-shaped inclined plates 510 are evenly and equidistantly fixed to the top of the U-shaped slide 54. The inverted "√" shaped plate of the J-shaped plate 511 is in contact with the top surface of the adjacent L-shaped inclined plate 510 on one side.A three-centimeter gap is left between the J-shaped plate 511 and the adjacent L-shaped inclined plate 510 on the other side (e.g., Figure 9 As shown), a two-centimeter gap is left between several cylinders 55. Through this structural arrangement, the loop-shaped carriage 54 drives several cylinders 55 and several J-shaped plates 511 to perform a undulating up-and-down sieving operation on the bentonite raw material. Each time the slide bar 53 moves laterally towards the grinding tank 2, the J-shaped plate 511 drives the extrusion plate 512 to extrude the bentonite raw material between itself and the adjacent L-shaped inclined plate 510. Furthermore, the inverted "√" shaped plate of the J-shaped plate 511 and the adjacent L-shaped inclined plate 510 extrude the bentonite raw material intercepted by the J-shaped plate 511 (from...). Figure 9 The state becomes Figure 10 (in the state of...), thereby achieving the purpose of crushing larger bentonite raw materials. When the slide bar 53 moves laterally towards the housing 3, through the above-mentioned structural arrangement, the J-shaped plate 511 will push the larger bentonite raw materials in the gap between it and the adjacent L-shaped inclined plate 510 away from the L-shaped inclined plate 510. The larger bentonite raw materials cross the L-shaped inclined plate 510 and fall onto the previous J-shaped plate 511 (from... Figure 10 The state becomes Figure 9 This allows the larger bentonite material in this area to be crushed again.

[0017] On one side, L-shaped frames 513 are fixed to the sides of the two elastic telescopic rods 59 that are close to each other. Triangular plates 515 are fixed between the tops of the two L-shaped frames 513 on one side, and triangular plates 514 are fixed between the tops of the two L-shaped frames 513 on the other side. Triangular plates 515 and 514 are used to block the gap between the two L-shaped inclined plates 510 on both sides and the inner wall of the machine casing 3. The setting of triangular plates 515 and 514 avoids the problem of bentonite raw material falling from the crushing roller group 4 falling into the gap between the two L-shaped inclined plates 510 on both sides and the machine casing 3.

[0018] In use, bentonite raw material is fed into the casing 3. The crushing roller group 4 crushes the bentonite raw material. The crushed bentonite raw material falls to the screw feeding assembly 31, which conveys the crushed bentonite to the grinding tank 2. The drive shaft 23 is driven by a motor to rotate, which in turn drives the grinding roller 22 to rotate. The grinding roller 22 and the grinding table 21 work together to grind the bentonite in the grinding tank 2. During the process of the crushed bentonite raw material falling to the screw feeding assembly 31, the crushed bentonite raw material passes through several J-shaped plates 511 and then through several cylinders 55. (It should be noted that since 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 on the other side is three centimeters, the particle size of the agglomerated bentonite intercepted by the J-shaped plates 511 is larger than the particle size of the agglomerated bentonite intercepted by the cylinders 55.) Several cylinders 55 and several J-shaped plates 511 screen the bentonite raw material. Larger bentonite raw materials are retained at the J-shaped plates 511 and cylinders 55 respectively, while smaller bentonite raw materials pass through the cylinders 55, thus achieving the screening operation of the crushed bentonite raw material. Through screening, it is ensured that the bentonite particle size entering the grinding tank 2 is relatively uniform, avoiding large-particle bentonite raw materials from entering the grinding stage, which can improve the efficiency of the grinding operation. During the rotation of the drive shaft 23, the drive shaft 23 drives the L-shaped scraper 51 to rotate. The L-shaped scraper 51 turns over the bentonite raw material entering the grinding tank 2, so that the bentonite raw material is evenly distributed on the grinding roller 22. By evenly distributing the bentonite raw material, excessive accumulation or density of bentonite raw material in certain areas of the grinding roller 22 is avoided, thereby reducing the risk of local excessive wear or blockage and improving the uniformity and efficiency of the grinding process. During the rotation of the L-shaped scraper 51, the L-shaped scraper 51 also drives the wavy annular groove disk 52 to rotate. The wavy annular groove of the wavy annular groove disk 52 pushes the slide rod 53 to move back and forth laterally. The slide rod 53 drives the second round block 57 to move back and forth. When the second round block 57 moves to the position of the first round block 56, the second round block 57 pushes the first round block 56 to drive the central cylinder 55 upward. The cylinder 55 drives the loop-shaped slide 54 to squeeze the extension end of the elastic telescopic rod 59. When the second round block 57 no longer pushes the first round block 56, under the elastic force of the second elastic telescopic rod 59, the second elastic telescopic rod 59 drives the loop-shaped slide 54 and the cylinder 59 to move back and forth. 5. Reset and move downwards, repeating this process, so that the loop slide 54 drives several cylinders 55 and several J-shaped plates 511 to perform up-and-down oscillating screening of bentonite raw materials. It should be noted that when the loop slide 54 drives the J-shaped plates 511 upwards, the J-shaped plates 511 will pull the telescopic end of the elastic telescopic rod 58 upwards; each time the slide rod 53 moves laterally towards the grinding tank 2, the slide rod 53 drives the J-shaped plates 511 to move along with it through the elastic telescopic rod 58. The J-shaped plates 511 move from the adjacent L-shaped inclined plate 510 to the L-shaped inclined plate 510 on the other side (from... Figure 9 The state becomes Figure 10 In this process, the J-shaped plate 511 will drive the extrusion plate 512 to move closer to the adjacent L-shaped inclined plate 510 on the other side, so that the extrusion plate 512 will squeeze the bentonite raw material between itself and the adjacent L-shaped inclined plate 510 on the other side. The inverted "√" shaped plate of the J-shaped plate 511 and the adjacent L-shaped inclined plate 510 on the other side will squeeze the bentonite raw material intercepted by the J-shaped plate 511, thereby achieving the purpose of crushing larger bentonite raw materials. During this process, when the crushing roller group 4 continuously feeds material, the J-shaped plate 511 and the adjacent L-shaped inclined plate 510 on the other side... 0 will continuously intercept larger bentonite materials, some of which will fall between the J-shaped plate 511 and its adjacent L-shaped inclined plate 510. Smaller bentonite materials will pass through the gap between the J-shaped plate 511 and its adjacent L-shaped inclined plate 510 (this gap is equal to the gap between several cylinders 55). Larger bentonite materials will be trapped here. When the slide bar 53 moves laterally towards the housing 3, the J-shaped plate 511 moves from the adjacent L-shaped inclined plate 510 on the other side to its adjacent L-shaped inclined plate 510 (from... Figure 10 The state becomes Figure 9 In this state, the J-shaped plate 511 will push the larger bentonite material in the gap between it and the adjacent L-shaped inclined plate 510 away from the L-shaped inclined plate 510. The larger bentonite material crosses the L-shaped inclined plate 510 and falls on the previous J-shaped plate 511, so that the larger bentonite material here can be crushed in the next operation.

[0019] Meanwhile, triangle plate 2 515 and triangle plate 1 514 respectively shield the gaps between the two L-shaped inclined plates 510 on both sides and the inner wall of the machine casing 3, thereby preventing the bentonite raw material falling from the crushing roller group 4 from falling into the gaps between the two L-shaped inclined plates 510 on both sides and the machine casing 3. It should be noted that each time the loop slide 54 squeezes the extension end of the elastic telescopic rod 2 59, when the extension end of the elastic telescopic rod 2 59 extends upward, the extension end of the elastic telescopic rod 2 59 will drive triangle plate 2 515 and triangle plate 1 514 to move upward through the L-shaped frame 513, so that the presence of triangle plate 2 515 and triangle plate 1 514 will not interfere with the operation of the J-shaped plate 511.

[0020] Please see Figure 1 - Figure 10 Based on the above embodiments, in another embodiment of the present invention, a heating component 6 is provided at the housing 3. The heating component 6 includes 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 housing 3, and the plurality of V-shaped heating plates 62 are evenly and equidistantly fixed at the bottom of the inverted "√" shaped plate of the J-shaped plate 511. The V-shaped heating plates 62 and the heating machine 61 are connected by 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 "√" shaped plate of the J-shaped plate 511. This allows the J-shaped plate 511 to heat the larger bentonite raw materials intercepted. The heating effect helps to evaporate the moisture in the bentonite raw materials, reduce their moisture content, and make the bentonite particles looser and weaken the internal cohesion. This facilitates the subsequent crushing of the bentonite raw materials and also helps with the subsequent grinding operation, improving the crushing efficiency and the quality of the final product.

[0021] A distribution device 7 is provided at the J-shaped plate 511. The distribution device 7 includes several diamond-shaped rollers 71, several friction wheels 72, and two friction plates 73. The two friction plates 73 are respectively fixed between the outer walls of the telescopic ends of two opposing elastic telescopic rods 59. The several diamond-shaped rollers 71 are respectively fixed to the top of the inverted "√" shaped plate of the J-shaped plate 511 near the extrusion plate 512 by brackets. The several friction wheels 72 are respectively fixed on both sides of the several diamond-shaped rollers 71. The outer walls of the friction wheels 72 and the tops of the friction plates 73 are both rough surfaces. The outer walls of the friction wheels 72 are in contact with the tops of the friction plates 73. Each time the J-shaped plate 511 moves, the distribution device 7 is distributed through the above structure. This process ensures that the bentonite raw material is evenly distributed onto the J-shaped plate 511 by the diamond roller 71. This process ensures that the bentonite raw material is evenly distributed on the surface of the J-shaped plate 511, avoiding the accumulation or uneven distribution of the bentonite raw material. When the J-shaped plate 511 heats the bentonite raw material, the even distribution ensures that the bentonite can absorb heat quickly and evenly, while avoiding the accumulation of bentonite raw material, which would prevent smaller pieces of bentonite from passing through the J-shaped plate 511. At the same time, the rotation of the diamond roller 71 can drive the bentonite raw material intercepted at the J-shaped plate 511 to rotate, thereby increasing the contact area between the bentonite raw material and the heating surface of the J-shaped plate 511 and promoting the uniform transfer of heat.

[0022] When in use, the heating machine 61 is started, which heats the V-shaped heating plate 62. The V-shaped heating plate 62 heats the inverted "√" shaped plate of the J-shaped plate 511, thereby heating the larger bentonite raw material intercepted by the J-shaped plate 511. The heating effect helps to evaporate the moisture in the bentonite raw material, reducing its moisture content. The bentonite particles become looser, and the internal binding force is weakened. This makes it easier for the bentonite raw material to be crushed in the subsequent process, and also helps with the subsequent grinding operation, improving the crushing efficiency and the quality of the final product.

[0023] Each time the J-shaped plate 511 moves, it drives the diamond roller 71 to move as well. The diamond roller 71 then drives the friction wheel 72 to move as well. Under the frictional force between the friction wheel 72 and the friction plate 73, the friction plate 73 drives the diamond roller 71 to rotate through the friction wheel 72. The rotation of the diamond roller 71 helps to evenly distribute the bentonite raw material onto the J-shaped plate 511. This process ensures that the bentonite raw material is evenly distributed on the surface of the J-shaped plate 511, avoiding the accumulation or uneven distribution of the bentonite raw material. When the J-shaped plate 511 heats the bentonite raw material subsequently, the even distribution ensures that the bentonite can absorb heat quickly and evenly, while avoiding the accumulation of bentonite raw material, which would prevent smaller pieces of bentonite from passing through the J-shaped plate 511. At the same time, the rotation of the diamond roller 71 can drive the bentonite raw material intercepted at the J-shaped plate 511 to rotate, thereby increasing the contact area between the bentonite raw material and the heating surface of the J-shaped plate 511 and promoting the uniform transfer of heat.
