The bottom end of the rotating rod is slidably embedded with a connecting rod, and the bottom end of the connecting rod is located at the bottom end of the rotating rod and is fixedly connected to the scraper 2. The top end of the rotating rod is located above the kettle body and is fixed with a motor 1. This patent can facilitate cleaning of the inner wall of the kettle body, and can conveniently adjust the position of the scraper, so as to avoid that the scraper always conflicts with the inner wall of the kettle body, thereby effectively avoiding wear of the scraper, thereby effectively improving the service life of the scraper.

[0004] The crystallization kettles currently available on the market have the following problems: during the use of the crystallization kettle, it is not easy to adjust the crystallization rate of the crystallization kettle by adjusting external factors, so it is not convenient to adjust the desired crystallization speed according to demand.

[0005] Therefore, it is necessary to design a crystallization kettle with an adjustable crystallization rate that is practical and can improve heat exchange efficiency. Summary of the Invention

[0006] The object of the present invention is to provide a crystallization kettle which is convenient for adjusting the crystallization rate, so as to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a crystallization kettle that is convenient for adjusting the crystallization rate, comprising an outer cylinder, a cylinder cover is provided on the top of the outer cylinder, an inner cylinder is provided on the bottom surface of the inner wall of the outer cylinder, an empty bin for accommodating refrigerant water is formed between the inner wall of the outer cylinder and the outer wall of the inner cylinder, a cooling device, a stirring device, a grinding device and a dispersing device are provided inside the outer cylinder; the cooling device comprises a valve, a water inlet, a water outlet and a water retention component, the bottom of the water inlet is fixed on the top surface of the cylinder cover, the valve is fixed on the top of the water inlet, and after the reactants inside the inner cylinder are fully mixed, the refrigerant water is injected into the cylinder through the valve above the cylinder cover. Water inlet, refrigerant water enters the empty space between the outer cylinder and the inner cylinder through the water inlet, the water outlet is fixed at the bottom of the outer wall of the outer cylinder, and is finally discharged through the water outlet. The water retention component is arranged on the inner wall of the outer cylinder. When it is necessary to adjust the speed of crystallization of the mixed liquid inside the inner cylinder, the staff controls the size of the valve opening to control the size of the refrigerant water inlet. Increasing the refrigerant water inlet makes the temperature difference between the inside of the inner cylinder and the outer cylinder always remain at the maximum, that is, improves the cooling efficiency, reducing the refrigerant water inlet makes the temperature difference between the inside of the inner cylinder and the outer cylinder reduce, that is, reduces the cooling efficiency, and thus achieves the purpose of controlling the crystallization rate of the mixed liquid.

[0008] According to the above technical solution, the water retention component includes a runner, a plurality of abutment plates and a plurality of water baffles. The runner is fixed between the inner wall of the outer cylinder and the outer wall of the inner cylinder. After the refrigerant water enters the empty chamber between the outer cylinder and the inner cylinder, the refrigerant water rotates and flows down along the runner. Compared with directly introducing the empty chamber, the refrigerant water will contact each section of the outer wall during the rotation process, which makes the efficiency of heat exchange of the refrigerant water higher, and prevents the refrigerant water from being discharged from the water outlet as soon as it enters the empty chamber, and fails to achieve the purpose of complete heat exchange; several of the abutment plates are fixed on the upper surface of the runner, several of the water baffles are fixed on the upper surface of the runner, and several of the abutment plates and a plurality of baffles are fixed on the upper surface of the runner. Springs are arranged between the water plates. When the refrigerant water rotates and flows down along the impeller, the water baffle arranged on the upper surface of the impeller will slow down the flow of the refrigerant water, which can increase the heat exchange time of the refrigerant water and make the refrigerant water more fully utilized; when the water flow increases, the water baffle approaches the abutment plate and compresses the spring between the two. When the water flow decreases, under the action of the spring force, the spring arranged between the abutment plate and the water baffle pushes the water baffle to rebound. In this way, when adjusting the water flow, the water baffle will make reciprocating motion, and the inner wall of the outer cylinder and the outer wall of the inner cylinder will be scraped by the movement of the water baffle to prevent scale from accumulating between the cylinder walls and affecting the cooling efficiency.

[0009] According to the above technical solution, the stirring device includes a rotating shaft, a propeller and a scraping assembly. The rotating shaft is fixed at the output end of the motor, and the motor is fixed on the upper surface of the cylinder cover. When the material mixture enters the inner cylinder, the staff starts the motor, and the motor drives the rotating shaft to rotate. The propeller is fixed at the middle of the outer wall of the rotating shaft, and the rotating shaft drives the propeller to rotate. The rotation of the propeller makes the solid material and liquid material in the inner cylinder more fully mixed, preventing undissolved solid material from mixing in during crystallization, resulting in the precipitated crystals being not pure enough. The scraping assembly is arranged inside the inner cylinder.

[0010] The filter bag is then moved back and forth to the filter bag filter area, so that the filter bag filter area is kept clean and the filter bag is easily moved.

[0011] According to the above technical solution, the grinding device includes a connecting rod, a grinding disc, a grinding box, an auxiliary grinding component and an erasing component. The connecting rod is fixed on the upper part of the outer wall of the rotating shaft. After the original material enters the grinding box, the rotating shaft drives the connecting rod to rotate. The grinding disc is fixed at the end of the connecting rod away from the rotating shaft. The connecting rod drives the grinding disc to rotate. The grinding box is fixed on the lower surface of the cylinder cover. The grinding disc rubs the bottom of the inner wall of the grinding box. A number of filter holes are provided on the outer wall of the grinding box. The connecting rod, grinding disc and auxiliary grinding component are arranged inside the grinding box. The material in the grinding box is ground and crushed by rotating the grinding disc, so that the material is easier to mix and dissolve after entering the inner cylinder through the grinding box, preventing large-particle solid materials from mixing into the precipitated crystals, preventing the crystals from being impure, and also preventing material waste. The auxiliary grinding component is arranged inside the grinding box, and the erasing component is arranged at the bottom of the grinding box.

[0012] According to the above technical solution, the research assistance component includes a research assistance plate and several research assistance blocks. The research assistance plate is fixed at the bottom of the grinding disc, and several research assistance blocks are fixed at the bottom of the grinding box. Several triangular through grooves are provided on the bottom of the research assistance plate. During the grinding process, large particles of material may not be able to enter the bottom of the grinding disc. The research assistance plate arranged at the bottom of the grinding disc will cause the large particles of material to be stuck in the triangular through grooves on its bottom. Several research assistance blocks are located on the movement trajectories of several triangular through grooves. During the movement, the research assistance blocks passing through the triangular through grooves will squeeze the large particles of material, so that after entering from the large entrance of the triangular through groove, they will exit from the small outlet after friction loss. This can help grind the large particles of material.

[0013] According to the above technical solution, the erasing assembly includes a cylinder, a wiping rod and a striking block. The cylinder is fixed at the bottom of the grinding box, the middle part of the wiping rod is rotatably connected to the outer wall of the cylinder, the cylinder and the wiping rod are connected by a torsion spring, and the striking block is fixed on the top of the filter cartridge. During stirring and mixing, part of the mixed liquid will splash on the bottom surface of the grinding box. When the filter cartridge moves left and right, the filter cartridge drives the striking block to move left and right. The end of the wiping rod away from the rotating shaft is located on the movement trajectory of the striking block. The striking block approaches and knocks the wiping rod, causing the wiping rod to rotate with the cylinder as the axis. When the striking block is away from the wiping rod, the wiping rod is reset under the action of the torsion spring, so that the wiping rod makes a reciprocating motion. The mixed liquid on the bottom surface of the grinding box is wiped off by the reciprocating motion of the wiping rod, thereby achieving the purpose of avoiding material waste.

[0014] According to the above technical solution, the dispersing device includes a feed port, a bulk port and a bulk assembly. The feed port is fixed on the upper surface of the cylinder cover, and the top surface of the bulk port is fixed on the lower surface of the cylinder cover. When the material enters through the feed port, the material falls into the bulk port and finally falls into the inside of the grinding box. The bulk assembly is arranged inside and on the bottom surface of the bulk port.

[0015] According to the above technical solution, the bulk material assembly includes a vertical rod, a vertical plate, a special-shaped rod and a rotating plate, one end of the vertical plate away from the discharge port is rotatably connected to the inner wall of the bulk material port, the vertical plate and the inner wall of the bulk material port are connected by a torsion spring, a through slot is provided on the side of the bulk material port away from the discharge port, one end of the rotating plate is fixed to the end of the vertical plate away from the discharge port, the rotating plate passes through the through slot, and the other end of the rotating plate is located on the movement trajectory of the scraper, when the scraper rotates close, the scraper hits the rotating plate, and the rotating plate drives the vertical plate to rotate, and when the scraper rotates away, the vertical plate is acted on by the torsion spring The vertical plate is reset to its original position, so that the vertical plate swings back and forth inside the bulk material port. The swing of the vertical plate allows the material to be scattered left and right and thrown into the grinding box, which is convenient for subsequent grinding operations. The vertical rod is fixed on the top of the vertical plate, and the vertical plate drives the vertical rod to swing. The vertical rod swings inside the feed port, which can prevent the material from blocking the feed port; the special-shaped rod is located on the bottom surface of the bulk material port. The special-shaped rod arranged on the bottom surface of the bulk material port will sweep the material falling on the upper surface of the grinding disc into the grinding box when the grinding disc passes by, so as to prevent some material from accumulating on the upper surface of the grinding disc and making it impossible to grind.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention arranges the cooling device so that the valve, water inlet and water outlet are coordinated. When the crystallization rate of the mixed liquid inside the inner cylinder needs to be adjusted, the staff controls the size of the valve opening to control the amount of refrigerant water inlet, thereby achieving the purpose of controlling the crystallization rate of the mixed liquid; the rotor, the abutment plate and the water baffle are coordinated so that the efficiency of heat exchange of the refrigerant water is higher, preventing the refrigerant water from being discharged from the water outlet as soon as it enters the empty chamber, thereby failing to achieve the purpose of complete heat exchange; at the same time, the inner wall of the outer cylinder and the outer wall of the inner cylinder are scraped by the movement of the water baffle to prevent scale from accumulating between the cylinder walls and affecting the cooling efficiency.

[0018] (2) The present invention arranges a stirring device so that the rotating shaft, propeller and scraping assembly cooperate. The rotation of the propeller makes the solid material and liquid material in the inner cylinder mix more fully, preventing the undissolved solid material from mixing into the crystals during precipitation, resulting in the precipitation of impure crystals; the scraper, hemisphere, filter cylinder and telescopic rod cooperate to scrape the output crystals precipitated on the inner wall of the inner cylinder, helping the crystals to precipitate and facilitating the subsequent opening of the cover to collect the output crystals; at the same time, the movement of the filter cylinder disrupts the rotating water flow in the inner cylinder, making the stirring more sufficient, preventing the material mixture and the propeller from running at the same speed, resulting in an unsatisfactory mixing effect.

[0019] (3) The present invention sets a grinding device so that the connecting rod, the grinding disc and the grinding box cooperate with each other, and the material in the grinding box is ground and crushed by the rotation of the grinding disc, so that the material is easier to mix and dissolve after entering the inner cylinder through the grinding box, thereby preventing large particles of solid materials from mixing into the precipitated crystals, preventing the crystals from being impure, and also preventing material waste; through the auxiliary grinding plate and a plurality of auxiliary grinding blocks, the auxiliary grinding blocks passing through the triangular groove during the movement of the grinding disc will squeeze the large particles of material, so that after entering from the large entrance of the triangular groove, they will exit from the small exit due to friction loss, thus helping the large particles of material to be ground; through the cylinder, the wiping rod and the striking block, the wiping rod makes a reciprocating motion, and the reciprocating motion of the wiping rod wipes the mixed liquid on the bottom surface of the grinding box, thereby achieving the purpose of avoiding material waste.

[0020] (4) The present invention cooperates with the feed port and the bulk material port through the arrangement of a dispersing device. When the material enters through the feed port, the material falls into the bulk material port and finally falls into the interior of the grinding box. The vertical rod, vertical plate, special-shaped rod and rotating plate cooperate with each other. The material can be dispersed and thrown into the grinding box by the swing of the vertical plate, which is convenient for subsequent grinding operations. At the same time, the vertical plate drives the vertical rod to swing, and the vertical rod swings in the feed port, which can achieve the purpose of preventing the material from blocking the feed port. At the same time, the special-shaped rod arranged on the bottom of the bulk material port will sweep the material falling on the upper surface of the grinding disc into the interior of the grinding box when the grinding disc passes by, so as to prevent part of the material from accumulating on the upper surface of the grinding disc and making it impossible to grind.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0032] See also Figure 1-4The present invention provides a technical solution: a crystallization kettle that is convenient for adjusting the crystallization rate, comprising an outer cylinder 11, a cylinder cover 12 is provided on the top of the outer cylinder 11, an inner cylinder 13 is provided on the bottom surface of the inner wall of the outer cylinder 11, an empty warehouse for accommodating refrigerant water is formed between the inner wall of the outer cylinder 11 and the outer wall of the inner cylinder 13, and a cooling device 2, a stirring device 3, a grinding device 4 and a dispersing device 5 are provided inside the outer cylinder 11; the cooling device 2 includes a valve 21, a water inlet 22, a water outlet 23 and a water retention component 24, the bottom of the water inlet 22 is fixed to the top surface of the cylinder cover 12, and the valve 21 is fixed on the top of the water inlet 22. After the reactants in the inner cylinder 13 are fully mixed, the refrigerant water is injected into the water inlet through the valve 21 above the cylinder cover 12 22. The refrigerant water enters the empty space between the outer tube 11 and the inner tube 13 through the water inlet 22, and the water outlet 23 is fixed at the bottom of the outer wall of the outer tube 11, and is finally discharged through the water outlet 23. The water retention component 24 is arranged on the inner wall of the outer tube 11. When it is necessary to adjust the crystallization rate of the mixed liquid inside the inner tube 13, the staff controls the opening size of the valve 21 to control the amount of refrigerant water inlet. Increasing the refrigerant water inlet makes the temperature difference between the inside of the inner tube 13 and the outer tube 11 always remain at the maximum, that is, improves the cooling efficiency. Reducing the refrigerant water inlet reduces the temperature difference between the inside of the inner tube 13 and the outer tube 11, that is, reduces the cooling efficiency, thereby achieving the purpose of controlling the crystallization rate of the mixed liquid.

[0033] The water retention component 24 includes a runner 241, a plurality of abutment plates 242 and a plurality of water baffles 243. The runner 241 is fixed between the inner wall of the outer cylinder 11 and the outer wall of the inner cylinder 13. After the refrigerant water enters the empty space between the outer cylinder 11 and the inner cylinder 13, the refrigerant water rotates and flows down along the runner 241. Compared with directly introducing the refrigerant water into the empty space, the refrigerant water will contact each section of the outer wall during the rotation process. This makes the efficiency of heat exchange of the refrigerant water higher, and prevents the refrigerant water from being discharged from the water outlet 23 as soon as it enters the empty space, and fails to achieve the purpose of complete heat exchange; a plurality of abutment plates 242 are fixed on the upper surface of the runner 241, a plurality of water baffles 243 are fixed on the upper surface of the runner 241, and a plurality of abutment plates 242 and a plurality of water baffles 243 are fixed between the runner 241 and the refrigerant water. A spring is provided between the impeller 241 and the water baffle 243 provided on the upper surface of the impeller 241 will slow down the flow of the refrigerant water during the process of the refrigerant water rotating downstream along the impeller 241, thereby increasing the heat exchange time of the refrigerant water and making fuller use of the refrigerant water; when the water flow increases, the water baffle 243 approaches the abutment plate 242 and compresses the spring between the two; when the water flow decreases, under the action of the spring force, the spring provided between the abutment plate 242 and the water baffle 243 pushes the water baffle 243 to rebound, so that when the water flow is adjusted, the water baffle 243 will make a reciprocating motion, and the inner walls of the outer cylinder 11 and the inner cylinder 13 are scraped off by the movement of the water baffle 243 to prevent scale from accumulating between the cylinder walls and affecting the cooling efficiency.

[0034] The stirring device 3 includes a rotating shaft 31, a propeller 32 and a scraping assembly 33. The rotating shaft 31 is fixed to the output end of the motor, and the motor is fixed to the upper surface of the cylinder cover 12. When the material mixture enters the inner cylinder 13, the staff starts the motor, and the motor drives the rotating shaft 31 to rotate. The propeller 32 is fixed to the middle of the outer wall of the rotating shaft 31, and the rotating shaft 31 drives the propeller 32 to rotate. The rotation of the propeller 32 makes the solid material and liquid material in the inner cylinder 13 more fully mixed, preventing undissolved solid material from mixing in during crystallization, resulting in the precipitated crystals being not pure enough. The scraping assembly 33 is arranged inside the inner cylinder 13.

[0035] The scraping assembly 33 includes a scraper 331, a semicircular ball 332, a filter cartridge 333 and a telescopic rod 334. The scraper 331 is fixed to the bottom of the rotating shaft 31. When the rotating shaft 31 rotates, the rotating shaft 31 drives the scraper 331 to rotate, and the scraper 331 scrapes the inner wall and bottom of the inner cylinder 13 to scrape the output crystals precipitated on the inner wall of the inner cylinder 13 by cooling, helping the crystals to precipitate, and facilitating the subsequent opening and collection of the output crystals; the telescopic rod 334 is fixed to the inner wall of the inner cylinder 13, the top of the filter cartridge 333 is fixed to the telescopic end of the telescopic rod 334, and the outer wall of the filter cartridge 333 is A number of through holes are opened, and the semi-circular balls 332 are fixed on the outer wall of the filter cartridge 333. The semi-circular balls 332 are located on the movement trajectory of the scraper 331. The scraper 331 repeatedly hits the semi-circular balls 332 on the outer wall of the filter cartridge 333 during the rotation process, causing the semi-circular balls 332 to swing left and right. The semi-circular balls 332 drive the filter cartridge 333 to swing left and right, thereby achieving the purpose of reciprocating motion of the filter cartridge 333. The movement of the filter cartridge 333 disrupts the rotating water flow in the inner cylinder 13, making the stirring more sufficient, and preventing the material mixture and the propeller 32 from moving at the same speed, resulting in an unsatisfactory mixing effect.

[0036] During use, after the reactants in the inner cylinder 13 are fully mixed, refrigerant water is injected into the water inlet 22 through the valve 21 above the cylinder cover 12. The refrigerant water enters the empty chamber between the outer cylinder 11 and the inner cylinder 13 through the water inlet 22 and is finally discharged through the water outlet 23. When it is necessary to adjust the speed of crystallization of the mixed liquid in the inner cylinder 13, the staff controls the opening size of the valve 21 to control the amount of refrigerant water inlet. Increasing the amount of refrigerant water inlet makes the temperature difference between the inside of the inner cylinder 13 and the outer cylinder 11 always remain at the maximum, that is, improve the cooling efficiency. Reducing the amount of refrigerant water inlet makes the temperature difference between the inside of the inner cylinder 13 and the outer cylinder 11 decrease, that is, reduce the cooling efficiency, thereby achieving the purpose of controlling the crystallization rate of the mixed liquid; after the refrigerant water enters the empty chamber between the outer cylinder 11 and the inner cylinder 13, the refrigerant water rotates and flows down along the impeller 241. Compared with directly introducing the refrigerant water into the empty chamber, the refrigerant water will The water baffle 243 contacts each section of the outer wall, which makes the heat exchange efficiency of the refrigerant water higher and prevents the refrigerant water from being discharged from the water outlet 23 as soon as it enters the empty chamber, and fails to achieve the purpose of complete heat exchange; at the same time, in the process of the refrigerant water rotating downstream along the impeller 241, the water baffle 243 arranged on the upper surface of the impeller 241 will slow down the flow of the refrigerant water, which can increase the heat exchange time of the refrigerant water and make the refrigerant water more fully utilized; when the water flow increases, the water baffle 243 approaches the abutment plate 242 and compresses the spring between the two. When the water flow decreases, under the action of the spring force, the spring arranged between the abutment plate 242 and the water baffle 243 pushes the water baffle 243 to rebound, so that when the water flow is adjusted, the water baffle 243 will make a reciprocating motion, and the inner walls of the outer cylinder 11 and the inner cylinder 13 are scraped off by the movement of the water baffle 243 to prevent scale from accumulating between the cylinder walls and affecting the cooling efficiency.

[0037] When the material mixture enters the inner cylinder 13, the staff starts the motor, the motor drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the propeller 32 to rotate. The rotation of the propeller 32 makes the solid material and the liquid material in the inner cylinder 13 more fully mixed, preventing the undissolved solid material from mixing in during crystallization, resulting in the precipitated crystals being not pure enough; at the same time, when the rotating shaft 31 rotates, the rotating shaft 31 drives the scraper 331 to rotate, and the scraper 331 scrapes the inner wall and bottom of the inner cylinder 13, and cools the solid material precipitated on the inner wall of the inner cylinder 13 The output crystals are scraped off to help the crystals to settle, making it convenient to open the cover and collect the output crystals later; at the same time, the scraper 331 repeatedly hits the semi-circular ball 332 on the outer wall of the filter cartridge 333 during the rotation process, causing the semi-circular ball 332 to swing left and right, and the semi-circular ball 332 drives the filter cartridge 333 to swing left and right, thereby achieving the purpose of reciprocating motion of the filter cartridge 333, and the movement of the filter cartridge 333 disrupts the rotating water flow in the inner cylinder 13, making the stirring more sufficient, and preventing the material mixture and the propeller 32 from moving at the same speed, resulting in an unsatisfactory mixing effect. Example 2

[0038] See also Figure 1-8 , based on Example 1, in this embodiment, a grinding device 4 and a dispersing device 5 are included.

[0039] The grinding device 4 includes a connecting rod 41, a grinding disc 42, a grinding box 43, an auxiliary grinding component 44 and an erasing component 45. The connecting rod 41 is fixed to the upper part of the outer wall of the rotating shaft 31. After the original material enters the grinding box 43, the rotating shaft 31 drives the connecting rod 41 to rotate, and the grinding disc 42 is fixed to the end of the connecting rod 41 away from the rotating shaft 31. The connecting rod 41 drives the grinding disc 42 to rotate, and the grinding box 43 is fixed on the lower surface of the cylinder cover 12. The grinding disc 42 rubs the bottom of the inner wall of the grinding box 43. The outer wall of the grinding box 43 is provided with a plurality of filtering holes. The connecting rod 41, the grinding disc 42 and the auxiliary grinding component 44 are arranged inside the grinding box 43. The material in the grinding box 43 is ground and crushed by the rotation of the grinding disc 42, so that the material is easier to mix and dissolve after entering the inner cylinder 13 through the grinding box 43, preventing large particles of solid materials from mixing into and precipitating crystals, preventing the crystals from being impure, and also preventing material waste. The auxiliary grinding component 44 is arranged inside the grinding box 43, and the erasing component 45 is arranged at the bottom of the grinding box 43.

[0040] The auxiliary research component 44 includes an auxiliary research plate 441 and several auxiliary research blocks 442. The auxiliary research plate 441 is fixed on the bottom of the grinding disc 42, and the several auxiliary research blocks 442 are fixed on the inner bottom surface of the grinding box 43. The bottom surface of the auxiliary research plate 441 is provided with several triangular grooves. During the grinding process, large particles of material may not be able to enter the bottom of the grinding disc. The auxiliary research plate 441 arranged at the bottom of the grinding disc 42 will make the large particles of material stuck in the triangular grooves on its bottom surface. Several auxiliary research blocks 442 are located on the movement trajectories of the several triangular grooves. During the movement, the auxiliary research blocks 442 passing through the triangular grooves will squeeze the large particles of material, so that after entering from the large entrance of the triangular groove, they will go out from the small outlet due to friction loss. This can help the large particles of material to be ground.

[0041] The erasing assembly 45 includes a cylinder 451, a wiping rod 452 and a striking block 453. The cylinder 451 is fixed to the bottom of the grinding box 43. The middle part of the wiping rod 452 is rotatably connected to the outer wall of the cylinder 451. The cylinder 451 and the wiping rod 452 are connected by a torsion spring. The striking block 453 is fixed to the top of the filter cartridge 333. When the mixing is carried out, part of the mixed liquid will be splashed from the bottom of the grinding box 43. When the filter cartridge 333 moves left and right, the filter cartridge 333 drives the striking block 453 to move left and right. The end of the wiping rod 452 away from the rotating shaft 31 is located on the movement trajectory of the striking block 453. The striking block 453 approaches and strikes the wiping rod 452, causing the wiping rod 452 to rotate with the cylinder 451 as the axis. When the striking block 453 is away from the wiping rod 452, the wiping rod 452 is reset under the action of the torsion spring, so that the wiping rod 452 reciprocates. The reciprocating motion of the wiping rod 452 wipes off the mixed liquid on the bottom surface of the grinding box 43, thereby achieving the purpose of avoiding material waste.

[0042] The dispersing device 5 includes a feed port 51, a bulk material port 52 and a bulk material assembly 53. The feed port 51 is fixed on the upper surface of the cylinder cover 12, and the top surface of the bulk material port 52 is fixed on the lower surface of the cylinder cover 12. When the material enters through the feed port 51, the material falls into the bulk material port 52 and finally falls into the inside of the grinding box 43. The bulk material assembly 53 is arranged inside and on the bottom surface of the bulk material port 52.

[0043] The bulk material assembly 53 includes a vertical rod 531, a vertical plate 532, a special-shaped rod 533 and a rotating plate 534. The end of the vertical plate 532 away from the discharge port is rotatably connected to the inner wall of the bulk material port 52. The vertical plate 532 and the inner wall of the bulk material port 52 are connected by a torsion spring. A through slot is provided on the side of the bulk material port 52 away from the discharge port. One end of the rotating plate 534 is fixed to the end of the vertical plate 532 away from the discharge port. The rotating plate 534 passes through the through slot. The other end of the rotating plate 534 is located on the movement track of the scraper 331. When the scraper 331 rotates close, the scraper 331 hits the rotating plate 534, and the rotating plate 534 drives the vertical plate 532 to rotate. When the scraper 331 rotates away, the vertical plate 532 is restored under the action of the torsion spring. The shaped rod 533 is located at the bottom of the bulk material port 52. The shaped rod 533 arranged at the bottom of the bulk material port 52 will sweep the material falling on the upper surface of the grinding disc 42 into the grinding box 43 when the grinding disc 42 passes by, so as to prevent some materials from accumulating on the upper surface of the grinding disc 42 and making it impossible to grind.

[0044] During use, after the original material enters the grinding box 43, the rotating shaft 31 drives the connecting rod 41 to rotate, and the connecting rod 41 drives the grinding disc 42 to rotate. The grinding disc 42 rubs against the bottom of the inner wall of the grinding box 43, and the material in the grinding box 43 is ground and crushed by the rotation of the grinding disc 42, so that the material is easier to mix and dissolve after passing through the grinding box 43 and entering the inner cylinder 13, thereby preventing large particles of solid materials from mixing in and precipitating crystals, preventing the crystals from being impure, and also preventing material waste; at the same time, during the grinding process, large particles of material may not be able to enter the bottom of the grinding disc, and the auxiliary grinding plate 441 arranged at the bottom of the grinding disc 42 will make the large particles of material stuck in the triangular groove on its bottom surface. During the movement, the auxiliary grinding block 442 passing through the triangular groove will squeeze Large particle materials enter from the large entrance of the triangular groove and exit from the small outlet after friction loss, which can help the large particle materials to be ground; at the same time, part of the mixed liquid will splash on the bottom of the grinding box 43 during stirring and mixing. When the filter cartridge 333 moves left and right, the filter cartridge 333 drives the striking block 453 to move left and right. The striking block 453 approaches and knocks the wiping rod 452, causing the wiping rod 452 to rotate with the cylinder 451 as the axis. When the striking block 453 moves away from the wiping rod 452, the wiping rod 452 is reset under the action of the torsion spring, so that the wiping rod 452 reciprocates, and the mixed liquid on the bottom of the grinding box 43 is wiped off by the reciprocating motion of the wiping rod 452, thereby achieving the purpose of avoiding material waste.

[0045] When the material enters the material inlet 51, the material falls into the bulk material inlet 52 and finally falls into the grinding box 43. When the scraper 331 rotates closer, the scraper 331 hits the rotating plate 534, and the rotating plate 534 drives the vertical plate 532 to rotate. When the scraper 331 rotates away, the vertical plate 532 is reset under the action of the torsion spring. In this way, the vertical plate 532 swings back and forth inside the bulk material inlet 52. The swing of the vertical plate 532 allows the material to be scattered left and right and thrown into the grinding box 43, which is convenient for subsequent grinding operations; at the same time, the vertical plate 532 drives the vertical rod 531 to swing, and the vertical rod 531 swings inside the material inlet 51, which can prevent the material from blocking the material inlet 51; at the same time, the special-shaped rod 533 arranged on the bottom surface of the bulk material inlet 52 will sweep the material falling on the upper surface of the grinding disc 42 into the grinding box 43 when the grinding disc 42 passes, thereby preventing some material from accumulating on the upper surface of the grinding disc 42 and making it impossible to grind.
