Description

Technical Field

[0001] This utility model relates to the field of chemical raw material processing technology, specifically a grinding device for chemical raw material processing. Background Technology

[0002] In chemical production, a variety of chemical raw materials are required, and these raw materials come in different states. Solid raw materials account for a certain number of types. In order to facilitate production and processing, solid raw materials need to be pretreated, and grinding is a commonly used pretreatment process.

[0003] A Chinese patent with publication number CN217189772U discloses a grinding device for processing solid chemical raw materials. The device includes a main body comprising a shell, a feed hopper, a finished product inlet, a waste inlet, and a supporting pillar. An internal structure is installed inside the main body, including a grinding chamber, a grinding trough, a feed inlet, a screening chamber, a screening inclined plate, and a finished product collection chamber. A grinding structure is installed inside the internal structure, comprising a grinding motor, a motor mounting rod, a motor output shaft, a grinding head, and crushing ridges. This grinding device for processing solid chemical raw materials is simple to operate, convenient to use, improves grinding efficiency, and also has a certain screening function, thus improving the quality of the finished product.

[0004] The aforementioned grinding device for processing solid chemical raw materials has a fixed distance between the grinding head and the grinding tank. This fixed grinding distance design cannot flexibly adjust the grinding distance according to the size of different chemical raw materials. If the distance is too large, coarse particles may remain due to incomplete grinding, reducing product quality. Furthermore, during the grinding process, the particle size of the chemical raw materials gradually decreases, and the thickness of the raw material layer decreases. The fixed grinding distance design cannot guarantee that the grinding head always applies sufficient pressure to the chemical raw materials during the grinding process, resulting in insufficient grinding force and affecting the grinding effect. Therefore, a grinding device for processing chemical raw materials is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a grinding device for processing chemical raw materials.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A grinding device for processing chemical raw materials, comprising a tank body, a grinding chamber provided inside the tank body, multiple perforations on the grinding chamber, two vertical plates fixedly connected to the top side of the tank body, each vertical plate having a sliding groove, and a lifting plate slidably mounted on the two sliding grooves, a first motor mounted on the lifting plate, the output end of the first motor connected to a rotating column, a grinding block fixedly connected to the bottom end of the rotating column, threaded rods rotatably mounted in each of the two sliding grooves, and the threaded rods penetrating the lifting plate, a first motor mounted on the top side of each of the two vertical plates, the output end of the first motor connected to the top end of the threaded rod, a discharge pipe connected to the bottom end of the tank body, and a valve mounted on the discharge pipe during grinding... To ensure effective grinding, the grinding spacing needs to be adjusted according to the particle size of the chemical raw materials. The control panel controls two primary motors to operate synchronously, causing the lifting plate to move the grinding blocks up or down. This allows for flexible adjustment of the grinding spacing based on the particle size of the raw materials. For larger particles, increasing the spacing can prevent uneven crushing or equipment damage due to excessive initial impact force. For smaller particles, decreasing the spacing enhances the grinding intensity, achieving a finer particle size and ensuring thorough and uniform grinding of all materials, thus improving product quality. Furthermore, as the particle size decreases during grinding, the material layer thickness decreases; reducing the grinding spacing ensures sufficient grinding force, further improving the grinding effect.

[0007] Preferably, connecting blocks are fixed to both sides of the circumferential surface of the tank, and a feed hopper is fixed to each of the two connecting blocks. A guide pipe connects the feed hopper to the tank. Two support frames are fixed to the top side of the tank, and a second motor is installed on each of the two support frames. The output end of the second motor is connected to a rotating rod, and the bottom end of the rotating rod is rotatably mounted on a horizontal plate. A horizontal plate is fixed to the inside of the bottom end of the tank. Multiple first crushing blades are fixed to the outer surface of the rotating rod, and multiple second crushing blades are fixed to the inner wall of the tank. The first and second crushing blades are staggered, which is beneficial for the chemical raw materials. During grinding, the chemical raw materials to be processed are first put into the feed hopper, and the second motor is started to make the first crushing blade rotate. With the cooperation of the second crushing blade, the chemical raw materials can be crushed into small particles. The crushed small particles are fed into the grinding chamber through the feed pipe for further fine grinding. By crushing the chemical raw materials into small particles first, compared with grinding large pieces of chemical raw materials directly, the contact area between the small particles and the grinding parts is greatly increased. In the subsequent grinding process, they can be ground and refined more quickly and thoroughly, which greatly shortens the overall grinding time and significantly improves the grinding efficiency.

[0008] Preferably, an annular inclined guide platform is fixed on the inner wall of the tank, and the annular inclined guide platform is located above the grinding chamber. When using the device, the annular inclined guide platform and the slope facilitate the better flow of materials into the grinding chamber.

[0009] Preferably, rod holes are provided on both side walls of the tank, and movable rods are inserted into both rod holes. A striking ball is fixed to one end of each movable rod, and a rod cap is fixed to the other end of each movable rod. A spring is fixed between the rod cap and the tank, and the spring is sleeved on the movable rod. Fixed posts are fixed to both side walls of the tank, and a second motor is mounted on each of the two fixed posts. Cams are installed at the output ends of the two second motors. During the grinding process, the fine particles after grinding will flow into the bottom of the tank through the leakage holes. To prevent the leakage holes from clogging, the grinding process is accelerated. The fine particles after grinding are fed more smoothly. By setting up a striking mechanism and operating it through the control panel, two second motors are controlled to work alternately, causing two cams to rotate. With the cooperation of the guide rod and the limit block, the cams push the movable rod to move back and forth, which in turn causes the striking ball to strike the outer wall of the grinding chamber. Through the continuous and regular striking of the grinding chamber by the striking ball, fine particles that are constantly generated during the grinding process and may clog the pores can be cleaned in time, avoiding pore blockage and keeping the pores unobstructed, so that the fine particles after grinding can be fed smoothly.

[0010] Preferably, two guide rods are fixedly connected to both sides of the tank body, and two limit blocks are slidably mounted on each guide rod. The two limit blocks are respectively fixed to the two sides of the rod cap. When using the device, the guide rods and limit blocks cooperate to enable the movable rod to move horizontally back and forth stably, thereby improving the movement stability of the movable rod.

[0011] Preferably, a control panel is installed on the outer wall of the tank, and the control panel is used to control the start and stop of the first motor, the second motor, the first motor and the second motor. When using this device, by setting up the control panel, the start and stop of multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.

[0012] The advantages of this utility model are:

[0013] 1. In use, this utility model controls two primary motors to operate synchronously via the control panel, causing the lifting plate to move the grinding blocks up or down. This allows for flexible adjustment of the grinding spacing according to the particle size of different raw materials. For larger particles, increasing the spacing can prevent uneven crushing or equipment damage due to excessive initial impact force. For smaller particles, decreasing the spacing enhances the grinding force, achieving a finer particle size and ensuring that all materials are thoroughly and uniformly ground, thus improving product quality. Furthermore, as the particle size of the raw material gradually decreases during grinding, the thickness of the raw material layer decreases. Reducing the grinding spacing ensures sufficient grinding force, improving the grinding effect.

[0014] 2. In the grinding process of this utility model, the fine particles after grinding will flow into the bottom of the tank through the leakage hole. In order to prevent the leakage hole from being blocked and to make the fine particles after grinding flow more smoothly, a striking mechanism is set up. The control panel controls two second motors to work alternately, causing two cams to rotate. With the cooperation of the guide rod and the limit block, the cams push the movable rod to move back and forth, which in turn causes the striking ball to strike the outer wall of the grinding chamber back and forth. Through the continuous and regular striking of the grinding chamber by the striking ball, the fine particles that are constantly generated during the grinding process and may block the leakage hole can be cleaned in time, avoiding the leakage hole blockage and keeping the leakage hole unobstructed, so that the fine particles after grinding can flow smoothly.

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figure 1-5As shown, a grinding device for processing chemical raw materials includes a tank 1, a grinding chamber 2 inside the tank 1, and multiple perforations 3 on the grinding chamber 2. Two vertical plates 4 are fixed to the top side of the tank 1, and each of the two vertical plates 4 has a sliding groove 5. A lifting plate 6 is slidably mounted on the two sliding grooves 5. A first motor 7 is mounted on the lifting plate 6, and the output end of the first motor 7 is connected to a rotating column 8. A grinding block 9 is fixed to the bottom end of the rotating column 8. Threaded rods 10 are rotatably installed in each of the two sliding grooves 5, and the threaded rods 10 pass through the lifting plate 6. A first motor 11 is mounted on the top side of each of the two vertical plates 4, and the output end of the first motor 11 is connected to the top end of the threaded rod 10. A discharge pipe 31 is connected to the bottom end of the tank 1, and a valve is mounted on the discharge pipe 31. During operation, in order to ensure the grinding effect, the grinding interval needs to be adjusted according to the particle size of the chemical raw materials. The control panel 32 controls the two first motors 11 to operate synchronously, causing the two threaded rods 10 to rotate simultaneously. This forces the lifting plate 6 to move the grinding block 9 up or down until the optimal grinding distance between the grinding block 9 and the grinding chamber 2 is reached. At this point, the first motors 11 stop operating. This allows for flexible adjustment of the grinding distance according to the particle size of different raw materials. For larger particles, increasing the distance can prevent uneven crushing or equipment damage due to excessive initial impact force. For smaller particles, decreasing the distance can enhance the grinding force, allowing the raw material to achieve a finer particle size. This ensures that all raw materials are ground thoroughly and uniformly, improving product quality. Simultaneously, as the particle size of the raw material gradually decreases during the grinding process, the thickness of the raw material layer decreases. By reducing the grinding distance, sufficient grinding force can be guaranteed, improving the grinding effect.

[0025] A control panel 32 is installed on the outer wall of the tank body 1, and the control panel 32 is used to control the start and stop of the first motor 7, the second motor 29, the first motor 11 and the second motor 16. When using this device, by setting the control panel 32, the start and stop of multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.

[0026] Please see Figure 3 and Figure 6As shown, connecting blocks 12 are fixed to both sides of the circumferential surface of the tank body 1. Feed hoppers 13 are fixed to both connecting blocks 12. A guide pipe 14 connects the feed hoppers 13 to the tank body 1. Two support frames 15 are fixed to the top side of the tank body 1. A second motor 16 is mounted on each support frame 15. The output end of the second motor 16 is connected to a rotating rod 17, and the bottom end of the rotating rod 17 is rotatably mounted on a horizontal plate 18. A horizontal plate 18 is fixed inside the bottom end of the tank body 1. Multiple first crushing blades 19 are fixed to the outer surface of the rotating rod 17, and multiple second crushing blades 20 are fixed to the inner wall of the tank body 1. The first crushing blades 19 and second crushing blades 20 are arranged alternately. During operation, when grinding chemical raw materials, the chemical raw materials to be processed are first... Raw materials are fed into the feed hopper 13. The second motor 16 is started, causing the rotating rod 17 to drive the first crushing blade 19 to rotate. With the cooperation of the second crushing blade 20, the chemical raw materials can be crushed into small particles. The crushed small particles are fed into the grinding chamber 2 through the feed pipe 14. The first motor 7 is started, causing the rotating column 8 to drive the grinding block 9 to rotate, thereby further refining the chemical raw materials. By first crushing the chemical raw materials into small particles, compared with directly grinding large pieces of chemical raw materials, the contact area between the small particles and the grinding parts is greatly increased. In the subsequent grinding process, they can be ground and refined more quickly and thoroughly, greatly shortening the overall grinding time and significantly improving the grinding efficiency.

[0027] An annular inclined guide platform 21 is fixed on the inner wall of the tank 1, and the annular inclined guide platform 21 is positioned above the grinding chamber 2. When using this device, by setting the annular inclined guide platform 21 and the slope setting, it is easier to better allow the material to flow into the grinding chamber 2.

[0028] Please see Figure 3-5As shown, rod holes are provided on both side walls of the tank body 1, and movable rods 22 are inserted into each rod hole. A striking ball 23 is fixed to one end of each movable rod 22, and a rod cap 24 is fixed to the other end of each movable rod 22. A spring 25 is fixed between the rod cap 24 and the tank body 1, and the spring 25 is sleeved on the movable rod 22. Fixed posts 28 are fixed to both side walls of the tank body 1, and a second motor 29 is mounted on each of the two fixed posts 28. A cam 30 is mounted on the output end of each of the two second motors 29. Two guide rods 26 are fixed to both side walls of the tank body 1, and limit blocks 27 are slidably mounted on each of the two guide rods 26. The two limit blocks 27 are respectively fixed to the side walls of the rod cap 24. During operation, during the grinding process… The fine particles after grinding will flow into the bottom of the tank 1 through the leakage hole 3. In order to prevent the leakage hole 3 from being blocked and to make the fine particles after grinding flow more smoothly, a striking mechanism is set up. The control panel 32 controls two second motors 29 to work alternately, causing two cams 30 to rotate. With the cooperation of the guide rod 26 and the limit block 27, the cams 30 push the movable rod 22 to move back and forth, which in turn causes the striking ball 23 to strike the outer wall of the grinding chamber 2. By striking the grinding chamber 2 continuously and regularly, the fine particles that are generated during the grinding process and may block the leakage hole 3 can be cleaned in time, avoiding the situation of the leakage hole 3 being blocked, keeping the leakage hole 3 unobstructed, and ensuring that the fine particles after grinding can flow smoothly.

[0029] Working Principle: Existing grinding devices for solid chemical raw material processing use a fixed distance between the grinding head and the grinding tank. This fixed grinding distance design cannot flexibly adjust the grinding distance according to the size of different chemical raw materials. If the distance is too large, incomplete grinding may result in coarse particle residue, reducing product quality. Furthermore, during grinding, the particle size of the chemical raw material gradually decreases, reducing the material layer thickness. The fixed grinding distance design cannot guarantee sufficient pressure from the grinding head on the chemical raw material throughout the grinding process, leading to insufficient grinding force and affecting the grinding effect. Therefore, to address these issues, a new grinding device for chemical raw material processing is proposed. During grinding, to ensure the grinding effect, the grinding distance needs to be adjusted according to the particle size of the chemical raw material. This is achieved through the control panel 32, which controls two primary motors 11. Synchronous operation causes both threaded rods 10 to rotate simultaneously, forcing the lifting plate 6 to move the grinding block 9 up or down until the distance between the grinding block 9 and the grinding chamber 2 reaches the optimal grinding distance. At this point, the first motor 11 stops operating. This allows for flexible adjustment of the grinding distance according to the particle size of different raw materials. For larger particles, increasing the distance appropriately can prevent uneven crushing or equipment damage due to excessive initial impact force. For smaller particles, decreasing the distance can enhance the grinding force, enabling the raw material to achieve a finer particle size, thus ensuring that all raw materials are fully and uniformly ground, improving product quality. Simultaneously, as the particle size of the raw material gradually decreases during the grinding process, the thickness of the raw material layer decreases. By reducing the grinding distance, sufficient grinding force can be guaranteed, improving the grinding effect.

[0030] When grinding chemical raw materials, the chemical raw materials to be processed are first put into the feed hopper 13. The second motor 16 is started, which causes the rotating rod 17 to drive the first crushing blade 19 to rotate. With the cooperation of the second crushing blade 20, the chemical raw materials can be crushed into small particles. The crushed small particles are put into the grinding chamber 2 through the feed pipe 14. The first motor 7 is started, which causes the rotating column 8 to drive the grinding block 9 to rotate, thereby further refining the chemical raw materials. By first crushing the chemical raw materials into small particles, compared with directly grinding large pieces of chemical raw materials, the contact area between the small particles and the grinding parts is greatly increased. In the subsequent grinding process, they can be ground and refined more quickly and thoroughly, which greatly shortens the overall grinding time and significantly improves the grinding efficiency.

[0031] During the grinding process, the fine particles after grinding flow into the bottom of the tank 1 through the vent 3. To prevent the vent 3 from becoming clogged and to ensure smoother discharge of the fine particles, a striking mechanism is set up. The control panel 32 operates the mechanism, which controls two second motors 29 to work alternately, causing two cams 30 to rotate. With the cooperation of the guide rod 26 and the limit block 27, the cams 30 push the movable rod 22 to move back and forth, thereby causing the striking ball 23 to strike the outer wall of the grinding chamber 2. By continuously and regularly striking the grinding chamber 2 with the striking ball 23, the fine particles that are constantly generated during the grinding process and may clog the vent 3 can be cleaned in time, preventing the vent 3 from becoming clogged and keeping the vent 3 unobstructed, ensuring that the fine particles after grinding can be discharged smoothly.
