Description

Technical Field

[0001] This utility model relates to a wet grinder, specifically, a wet grinder with a cleaning function. Background Technology

[0002] A wet grinding mill is a mechanical device that uses a liquid medium to assist in grinding. It is mainly used to crush solid materials into ultrafine particles at the micron or nanometer level, and to grind materials into powder. After the grinding work is completed, material residues easily adhere to the grinding surfaces inside the wet grinding mill. The adhered material hinders the effective contact between the grinding surfaces, resulting in a decrease in grinding efficiency and requiring a longer time to reach the target fineness. At the same time, the adhered material causes uneven pressure distribution in the grinding area, and the finished product may contain coarse particles or insufficiently ground material. Furthermore, the long-term accumulation of the adhered material can easily mix with other batches of material, causing cross-contamination. Therefore, workers need to regularly clean the material residues on the grinding surfaces to ensure the long-term efficient operation of the grinding mill.

[0003] An existing wet grinding mill features a reverse-rotating double-disc structure. This design uses two grinding discs rotating at high speed in opposite directions, generating strong shearing and collision forces. This causes the material to be repeatedly squeezed and torn between the discs, achieving ultrafine grinding. However, in this type of wet grinding mill, the opposite sides of the two grinding discs are designated as the grinding surface, and the gap between the two grinding surfaces is relatively narrow. When workers clean material adhering to this grinding surface, it is difficult to insert cleaning tools into the gap between the two grinding discs to remove residual material. When using a high-pressure water gun to wash the grinding surfaces of the two grinding discs, the washing direction is also restricted, resulting in dead corners that cannot be washed away, affecting the cleaning quality of the grinding surface. To ensure the cleaning quality of the grinding surface, workers usually need to disassemble and clean the two grinding discs, which consumes a lot of time and reduces the grinding efficiency of the mill.

[0016] 1. This wet grinding machine with cleaning function allows the worker to use the lifting component to move the conical head out of the grinding bucket assembly. Then, the worker moves the nozzle on the hollow cylinder to a position between the conical head and the grinding surface of the grinding bucket body. This allows the grinding fluid sprayed from the nozzle to wash the grinding surfaces of the conical head and the grinding bucket body. During the washing process, the rotating component drives the grinding bucket body to rotate slowly, and the drive component drives the conical head to rotate slowly. The worker also holds the handle and moves the hollow cylinder back and forth, continuously adjusting the height of the nozzle. This ensures that the grinding fluid sprayed from both nozzles thoroughly washes away the material residue adhering to the grinding surface, improving the worker's cleaning efficiency.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0039] Example 1

[0040] Please see Figures 1-9 As shown, one of the objectives of this embodiment is to provide a wet grinding machine with a cleaning function, including a frame 1. The frame 1 consists of several square frames touching the ground and a top plate fixed to the upper side of the square frames. A ladder connecting the top plate and the ground is fixedly installed on one side of the frame 1. A wet grinding mechanism 2 is provided on the frame 1. The wet grinding mechanism 2 includes a grinding cylinder 22 fixedly installed on the frame 1. A grinding bucket assembly 25 is provided inside the grinding cylinder 22 near the bottom. The grinding bucket assembly 25 includes a grinding bucket body 251 coaxially rotatably installed inside the grinding cylinder 22 near the bottom. A rotating component is provided on one side of the grinding bucket body 251 for driving the grinding bucket body 251 to rotate. The grinding bucket body 251 is a bowl-shaped structure with the opening facing upward. The outer edge sidewall of the upper end of the grinding bucket body 251 contacts the inner circumference of the grinding cylinder 22, and the upper edge of the grinding bucket body 251 is located above the rotating component. The grinding bucket body 251 prevents the material inside the grinding cylinder 22 from contacting the rotating component, thereby ensuring the normal operation of the rotating component.

[0041] Meanwhile, a grinding head 29 is coaxially arranged inside the grinding cylinder 22. A conical head 291 is coaxially fixed to the lower side wall of the grinding head 29. The conical head 291 and the grinding head 29 are a prefabricated structure integrally formed. A drive assembly 245 is arranged on the upper side of the grinding cylinder 22. The drive assembly 245 is used to drive the grinding cylinder 22 to rotate around the axis of the grinding cylinder 22. When the wet grinder is in the grinding material state, the conical head 291 is located inside the grinding hopper body 251. A grinding gap is formed between the conical side wall of the conical head 291 and the conical inner wall of the grinding hopper body 251, and the width of the grinding gap decreases in the direction away from the grinding head 29. The conical side wall of the conical head 291 and the conical inner wall of the grinding hopper body 251 are set as the grinding surface. A feed pipe 222 is fixed, and an end cap is threaded to the upper end of the feed pipe 222. When the wet grinder is in the process of grinding materials, the worker uses a ladder to transport the material to be ground to the upper side wall of the top plate of the frame 1. Then, the end cap is opened and the material is fed into the grinding cylinder 22 through the feed pipe 222. The material inside the grinding cylinder 22 slides into the grinding gap under the action of gravity. The worker then operates the rotating component to drive the grinding bucket body 251 to rotate, and operates the drive component 245 to drive the conical head 291 to rotate in the opposite direction to the grinding bucket body 251. During this process, the grinding surfaces of the conical head 291 and the grinding bucket body 251 rotate relative to each other, and the grinding surfaces of the conical head 291 and the grinding bucket body 251 perform efficient grinding of the material in the grinding gap.

[0042] To enable the wet grinding mill to perform wet grinding of materials, I-shaped grooves are provided on one side of the grinding cylinder 22 and the top of the frame 1. A hollow cylinder 26 is slidably fitted inside both I-shaped grooves. The cross-section of the hollow cylinder 26 is an I-shaped structure adapted to the I-shaped grooves. The hollow cylinder 26 seals the I-shaped grooves, preventing material inside the grinding cylinder 22 from leaking to the outside through the I-shaped grooves. One end of the hollow cylinder 26 extends into the interior of the grinding cylinder 22 and... Two nozzles 261 are fixed in place. An I-shaped groove restricts the rotation of the hollow cylinder 26, keeping the nozzles 261 in a fixed spraying direction. A water inlet pipe 262 is fixedly connected to the side wall of the hollow cylinder 26 near one end. The other end of the water inlet pipe 262 is connected to the drain pipe of a water pump. The pump's suction pipe is connected to the interior of the grinding fluid tank. When the wet grinder is grinding materials, the nozzles 261 are located on the circumferential side wall of the grinding head 29 and within the circumference of the grinding cylinder 22. Between the walls, when the rotating conical head 291 and the grinding bucket body 251 grind the material, an external water pump pumps the grinding liquid into the hollow cylinder 26 through the water inlet pipe 262. The grinding liquid inside the hollow cylinder 26 is sprayed onto the side wall of the grinding head 29 and the inner wall of the grinding cylinder 22 through two nozzles 261. Then, the grinding liquid flows to the grinding surface of the conical head 291 and the grinding bucket body 251 under the action of gravity and mixes with the material being ground. The material being ground will rotate with the conical head 291 and the grinding bucket body 251, and the rotating material will be fully mixed with the grinding liquid, so that the wet grinder can perform wet grinding of the material. During the wet grinding process, the grinding liquid will settle the powdered material, preventing the material from forming dust and adhering to the inner wall of the grinding cylinder 22 and the upper part of the grinding head 29, thereby reducing the cleaning pressure of the worker and making it easier for the worker to clean the wet grinder.

[0043] To ensure the stability of the nozzle 261 during the spraying of grinding fluid, a barrier 11 is fixedly installed at the edge of the upper side wall of the frame 1. The barrier 11 can prevent workers standing on the top plate side wall of the frame 1 from accidentally falling, thus improving the safety of workers during operation. A locking component 265 is installed on one side of the barrier 11 near the upper end. At the same time, handles 263 are fixedly installed on both sides of the hollow cylinder 26 near the upper end. The other end of the handle 263 is fixedly connected to an inverted L-shaped hook 264. When the nozzle 261 is located between the circumferential side wall of the grinding head 29 and the circumferential inner wall of the grinding cylinder 22, the locking component 265 fixes the position of the hook 264, thereby limiting the changes in the position of the hollow cylinder 26 and the nozzle 261 and ensuring the stability of the nozzle 261 during the spraying of grinding fluid.

[0044] The structure of locking component 265 is detailed below, refer to Figure 8The locking component 265 includes a U-shaped frame 2651 horizontally fixed on the enclosure 11. Sliding sleeves 2652 are slidably fitted on opposite sides of the U-shaped frame 2651. A retaining sleeve 2653 is fixedly installed on the lower side wall of the sliding sleeve 2652. A connecting rod 2654 is fixedly installed between the two retaining sleeves 2653. When the nozzle 261 is located between the circumferential side wall of the grinding head 29 and the circumferential inner wall of the grinding cylinder 22, the two retaining sleeves 2653 are respectively fitted on the ends of the two hooks 264 away from the handle 263. The movable direction of the retaining sleeves 2653 is different from the movable direction of the hooks 264. Therefore, the retaining sleeves 2653 will restrict the movement of the hooks 264, thereby restricting the hollow cylinder 26 from sliding along the inner wall of the I-shaped groove, ensuring the stability of the nozzle 261 during the spraying of the grinding fluid.

[0045] Meanwhile, a through hole 221 is provided at the center of the bottom of the grinding cylinder 22. A positioning post 23 is coaxially arranged inside the through hole 221. The positioning post 23 and the grinding cylinder 22 are fixedly connected by several extension rods 231. Specifically, several extension rods 231 are fixedly arranged in a ring array at the lower end of the positioning post 23. The other end of the extension rod 231 is fixed to the lower side wall of the grinding cylinder 22 by bolts. A discharge gap is formed between the side wall of the positioning post 23 and the inner wall of the through hole 221. A conical groove is provided in the middle of the upper side wall of the positioning post 23. When the conical head 291 is located inside the grinding bucket body 251, the lower end of the conical head 291 contacts the inner wall of the conical groove. The conical groove restricts the lateral movement of the conical head 291, thereby improving the stability of the conical head 291 during rotation and improving the grinding quality of the material by the conical head 291. When the mixture of the material and grinding liquid that has been ground into fine powder falls out from the grinding gap under the action of gravity, the mixture passes through... The material falls through the discharge gap onto the outside of the grinding cylinder 22. A base 21 is fixedly installed at the lower end of the grinding cylinder 22, with its lower side wall touching the ground. The base 21 supports the grinding cylinder 22, thus improving its stability. A funnel-shaped receiving groove 211 is formed on the upper side wall of the base 21, communicating with the through hole 221. An inclined discharge groove 212 is formed inside the base 21, with one end of the discharge groove 212 connecting to the lower end of the receiving groove 211. The two ends of the discharge trough 212 are connected, and the other end of the discharge trough 212 passes through the circumferential side wall of the base 21. A discharge pipe is fixed on the side wall of the base 21 at a position corresponding to the discharge trough 212. Before the grinding operation begins, the worker places the container for holding the material below the discharge pipe. After the ground material is discharged from the grinding cylinder 22, the material first enters the inside of the receiving trough 211, then enters the inside of the discharge trough 212, and is then discharged into the container through the discharge pipe, thereby collecting the ground material.

[0046] To drive the grinding bucket body 251 to rotate, the structure of the rotating assembly is detailed below. The rotating assembly includes an internal gear 252 coaxially fixed on the outer circumference of the grinding bucket body 251. A first motor 253 is fixedly installed on one side of the grinding cylinder 22. An external gear 254 is coaxially fixed on the output shaft of the first motor 253. A movable groove communicating with the inside of the grinding cylinder 22 is opened on one side of the grinding cylinder 22. The bowl-shaped grinding bucket body 251 can prevent material from leaking to the outside of the grinding cylinder 22 through the movable groove. One side of the external gear 254 passes through the movable groove and meshes with the external gear 254. When the output shaft of the first motor 253 drives the external gear 254 to rotate, the internal gear 252 drives the grinding bucket body 251 to rotate around the axis of the grinding bucket body 251 through the meshing transmission of the external gear 254 and the internal gear 252, so that the grinding bucket body 251 can rotate relative to the conical head 291 to grind the material in the grinding gap.

[0047] To drive the conical head 291 to rotate, and to facilitate subsequent cleaning of the grinding surfaces of the conical head 291 and the grinding bucket body 251 by workers, two support plates 281 are symmetrically fixed on the upper side wall of the grinding cylinder 22. The feed pipe 222 is located between the two support plates 281. An assembly cylinder 28 is fixedly installed at the upper end of the two support plates 281. A lifting assembly 24 is installed on the upper side of the grinding cylinder 22. The lifting assembly 24 is used to drive the grinding head 29 to move vertically. The following describes the lifting assembly 24. The structure of component 4 is further refined. The lifting assembly 24 includes a main shaft 241 coaxially fixed to the upper end of the grinding head 29. The upper end of the main shaft 241 slides and rotates through the upper side wall of the grinding cylinder 22 and the lower side wall of the assembly cylinder 28, extending into the interior of the assembly cylinder 28. When the main shaft 241 rotates, it drives the grinding head 29 and the conical head 291 to rotate synchronously. To limit the vertical movement of the main shaft 241, the grinding head 29 and the conical head 291 are kept stable inside the grinding cylinder 22. A lifting plate 242 is rotatably mounted on the main shaft 241 between two support plates 281. The lifting plate 242 and the main shaft 241 move up and down synchronously. Guide grooves 282 are provided on the support plates 281. The two ends of the lifting plate 242 pass through the two guide grooves 282 and extend outward. Electric telescopic rods 243 are fixedly installed on both sides of the assembly cylinder 28 by brackets. The lower ends of the piston rods of the two electric telescopic rods 243 are fixedly connected to the two ends of the lifting plate 242. The electric telescopic rods 243 drive the lifting plate 242 and the main shaft 241 to move vertically. At the same time, a second motor 27 and a reduction gearbox 271 are fixedly installed on the upper side wall of the frame 1 by brackets. The output shaft of the second motor 27 is coaxially fixedly connected to the input shaft of the reduction gearbox 271. When the output shaft of the second motor 27 drives the input shaft of the reduction gearbox 271 to rotate, the output shaft of the reduction gearbox 271 rotates at a slower speed, so that the output shaft of the reduction gearbox 271 can serve as the power source to drive the rotation of the main shaft 241.

[0048] To enable the output shaft of the gearbox 271 to drive the main shaft 241 to rotate, the structure of the drive assembly 245 is detailed below. The drive assembly 245 includes a drive shaft 2455 coaxially fixed to the output shaft of the gearbox 271. One end of the drive shaft 2455 rotatably passes through one side of the assembly cylinder 28 and is coaxially fixed with a driving bevel gear 2456. A transmission shaft 2451 is rotatably mounted on the top side inside the assembly cylinder 28. A driven bevel gear 2454 is coaxially fixed on the transmission shaft 2451. The driven bevel gear 2454 meshes with the driving bevel gear 2456. When the output shaft of the gearbox 271 drives the driving bevel gear 2456 to rotate, the meshing transmission between the driving bevel gear 2456 and the driven bevel gear 2454 causes the driven bevel gear 2454 to drive the transmission shaft 2451 to rotate. The drive assembly 245 also includes a drive disc 2452 coaxially fixed at the lower end of the transmission shaft 2451. The lower side wall of the drive disc 2452... Two slide rods 2453 are symmetrically fixedly connected. The two slide rods 2453 here are the minimum number. There can be three or more slide rods 2453. A driven disc 244 is coaxially fixed on the end of the main shaft 241 located inside the assembly cylinder 28. The electric telescopic rod 243 drives the main shaft 241 and the driven disc 244 to move vertically. During the vertical movement, the driven disc 244 is always slidably sleeved on the side wall of the two slide rods 2453. When the drive shaft 2451 drives the drive disc 2452 to rotate, the drive disc 2452 drives the two slide rods 2453 to rotate. The two slide rods 2453 drive the driven disc 244 to rotate synchronously. The rotating driven disc 244 causes the main shaft 241 and the lifting plate 242 to rotate relative to each other. The rotating main shaft 241 drives the grinding head 29 and the conical head 291 to rotate synchronously, so that the rotating conical head 291 cooperates with the grinding bucket body 251 rotating in the opposite direction to perform efficient grinding of materials.

[0049] Both electric telescopic rods 243 are electrically connected to an external control device. This external control device can control the piston rods of the two electric telescopic rods 243 to extend and retract synchronously. The extension and retraction of the piston rods of the two electric telescopic rods 243 drives the lifting plate 242 to move vertically. Simultaneously, the side wall of the lifting plate 242 slides in contact with the inner wall of the guide groove 282. The guide groove 282 improves the stability of the lifting plate 242 during vertical movement. When the wet grinding machine is idle, and the worker needs to clean the material adhering to the grinding surface of the conical head 291 and the grinding bucket body 251, the operator controls the piston rods of the two electric telescopic rods 243 to extend and retract synchronously. The retraction causes the piston rod of the electric telescopic rod 243 to move the lifting plate 242 upward. The upward movement of the lifting plate 242 causes the main shaft 241, grinding head 29, driven plate 244, and conical head 291 to move upward synchronously, thus switching the wet grinder to the cleaning state. At this time, the conical head 291 is away from the grinding bucket body 251. When the wet grinder is in the cleaning state, the conical head 291 is located on the upper side of the grinding bucket body 251. Then, the worker holds the connecting rod 2654 and pulls the two clamping sleeves 2653 towards the enclosure 11, causing the clamping sleeves 2653 to drive the corresponding sliding sleeves 2652 to slide along the opposite sides of the U-shaped frame 2651 until... The ferrule 2653 disengages from the corresponding hook 264, thereby releasing the locking component 265 from restricting the position of the hook 264. The worker then holds the handle 263 and moves the hollow cylinder 26 along the inner wall of the I-shaped groove away from the U-shaped frame 2651, positioning the nozzle 261 between the conical sidewall of the conical head 291 and the conical inner wall of the grinding bucket body 251. An external water pump then pumps the grinding fluid into the hollow cylinder 26 at higher pressure, causing the grinding fluid to be sprayed at high speed onto the grinding surfaces of the conical head 291 and the grinding bucket body 251. During this process, the rotating component drives the grinding bucket body 251 to rotate slowly, causing the drive component 2... 45 drives the conical head 291 to rotate slowly, while the worker holds the handle 263 and moves the hollow cylinder 26 back and forth, constantly adjusting the height of the nozzle 261 so that the grinding liquid sprayed by the two nozzles 261 can fully contact the grinding surface of the conical head 291 and the grinding bucket body 251, so that the grinding liquid can fully wash away the material residue adhering to the grinding surface. The washed-off material residue will be discharged outward through the discharge chute 212. Before cleaning the wet grinder, the worker places the container for collecting material residue and grinding liquid under the discharge pipe, so that the material residue and grinding liquid can be collected through the container, which is convenient for recycling.

[0050] Meanwhile, a middle baffle 111 is horizontally fixed on the enclosure 11. When the locking component 265 releases the lock on the hook 264, the hook 264 can move with the hollow cylinder 26. As the hollow cylinder 26 moves diagonally downward along the inner wall of the I-shaped groove, the hook 264 will contact the upper side wall of the middle baffle 111. At this time, the middle baffle 111 will prevent the hook 264 and the hollow cylinder 26 from moving further downward. At this time, the two nozzles 261 will spray the grinding fluid onto the lowest point of the conical head 291 and the grinding bucket assembly 25. The middle baffle 111 restricts the nozzles 261. The lower limit of movement is reached when the hollow cylinder 26 moves obliquely upward along the inner wall of the I-shaped groove. At this time, the nozzle 261 will contact the inner wall of the grinding cylinder 22. The inner wall of the grinding cylinder 22 will continue to move upward along the hollow cylinder 26. The two nozzles 261 will spray the grinding liquid onto the uppermost part of the conical head 291 and the grinding bucket assembly 25. The upper and lower limits of the worker's movement of the hollow cylinder 26 are limited by the intermediate baffle 111 and the nozzles 261. During the worker's reciprocating movement of the hollow cylinder 26, it is ensured that the grinding liquid sprayed by the nozzles 261 can wash away the material residue and avoid wasting the grinding liquid.
