Description

Technical Field

[0001] The invention belongs to the technical field of activated carbon preparation, and more specifically, particularly relates to a high-efficiency grinding device for activated carbon preparation. Background Art

[0002] In the process of preparing activated carbon, efficient grinding equipment is needed to finely grind the raw materials. The efficient grinding equipment used in the preparation of activated carbon can finely grind the raw material particles of activated carbon into the required particle size, increase the surface area and adsorption performance of activated carbon, thereby improving the adsorption performance and utilization rate of activated carbon. When selecting grinding equipment, it is necessary to consider factors such as production scale, raw material characteristics, and grinding particle size requirements to ensure that the performance and efficiency of the equipment can meet production needs.

[0003] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: 1. The humidity and hardness of the raw materials will affect the effect of the grinding equipment. If the humidity and hardness parameters of the activated carbon raw materials do not meet the requirements, the raw materials will not be ground sufficiently during grinding, and the insufficiently ground raw materials will fall from the discharge port along with the activated carbon. Therefore, the finished activated carbon product will be mixed with some raw material fragments, resulting in a decrease in product quality.

[0004] 2. When the grinding equipment is ground into powder particles of different radii, it is usually necessary to clean the grinding equipment to prevent the materials of the previous batch of products from affecting the next batch of products. However, since the inside of the discharge device is relatively high, the staff cannot reach the deeper inner wall of the discharge device during manual cleaning, which reduces the cleaning effect. 3. Since the activated carbon after grinding is light in weight, when the grinding device is unloaded, part of the product will adhere to the inner wall of the discharging device and cannot fall down. The attached finished product cannot be collected, which will cause waste and reduce the output of the finished product.

[0005] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a high-efficiency grinding equipment for the preparation of activated carbon is provided, in order to achieve a more practical purpose. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing a screen, when the activated carbon falls from the discharging device, it will first pass through the screen, at this time, the motor is started, the motor drives the left connecting short rod 1 to rotate, at this time the left rotating bevel gear 2 drives the corresponding meshing bevel gear 2 to rotate, at this time the long rod will start to rotate, the long rod will drive the two rotating bevel gears 2 and the two connecting short rods 1 to rotate synchronously, the two connecting short rods 1 will drive the rotating gear 2 to rotate, the rotating gear 2 has only one-quarter of the teeth, so the rotating gear 2 rotates when it meshes with the two gear bars, which will drive the two gear bars and the two lifting columns to rise, and the lifting columns When it rises, it will drive the two moving plates and the screen to rise. At this time, the two springs are stretched. When the rotating gear two cancels the meshing with the gear bar, the spring rebounds and drives the gear bar and the screen to its original position. At this time, the rotating gear two will continue to drive the gear bar and the screen to rise after rotating one circle. The screen repeats the rising and falling operations to achieve the purpose of simulating the vibration of the screen. At this time, the vibration of the screen will screen the activated carbon on the screen. At this time, the finished product discharged from the discharge device will not be mixed with raw material fragments, avoiding the problem that the finished activated carbon product will be mixed with some raw material fragments and cause the quality of the product to decline, so that the quality of the finished product is not affected.

[0018] In the present invention, by providing a lifting column, the grooves on the two fixed frames will resist the two lifting columns, so that the two rotating gears 2 can only move in the vertical direction when driving the gear bar and the lifting column to move, thereby avoiding the problem that the rotating gear 2 and the gear bar cannot be accurately meshed due to the deviation of the lifting column, and improving the stability of the lifting column and the gear bar during lifting.

[0019] In the present invention, a movable short rod is provided, and the lower end position of the movable short rod is always located inside the fixed plate. Therefore, the movable short rod plays a limiting role when the screen simulates vibration. When the two movable plates drive the screen to vibrate, the problem that the two movable plates may be shifted in position due to the excessively high vibration frequency is avoided. Since the lower end position of the movable short rod is always located inside the fixed plate, the two movable plates can only move vertically.

[0020] In the present invention, by providing a rotating bevel gear 1, when the discharge device on the grinding body needs to be cleaned, the motor is started and the long rod is rotated. At this time, the meshing bevel gear 1 on the long rod will also rotate. The meshing bevel gear 1 will drive the rotating bevel gear 1 and the connecting short rod 2 to rotate.

[0022] In the present invention, a fixed frame is provided. Since limiting grooves are provided at both ends of the discharge device on the grinding body, part of the activated carbon will overflow from the two limiting grooves when the material is discharged from the discharge port.

The two fixed plates 14 are located at the lower end positions of the two springs 13, and the two fixed plates 14 are fixedly connected with the discharging device 3. The upper surfaces of the two fixed plates 14 are penetrated with circular holes corresponding to the positions of the two movable short rods 16. When the activated carbon When falling from the discharging device 3, it will first pass through the screen 19, at this time, the motor 5 is started, and the motor 5 drives the left connecting short rod 1 26 to rotate. At this time, the rotating bevel gear 2 29 on the left drives the corresponding meshing bevel gear 2 30 to rotate, and the long rod 6 will start to rotate. The long rod 6 will drive the two rotating bevel gears 29 and the two connecting short rods 1 26 to rotate synchronously. The two connecting short rods 1 26 will drive the rotating gear 2 28 to rotate. There are only one-quarter teeth on the rotating gear 28. Therefore, when the rotating gear 28 is meshed with the two gear strips 7, it will drive the two gear strips 7 and the two lifting columns 8 to rise. When the lifting column 8 rises, it will drive the two The movable plate 12 and the screen 19 rise, and the two springs 13 are stretched at this time. When the rotating gear 28 cancels the meshing with the gear bar 7, the spring 13 rebounds and drives the gear bar 7 and the screen 19 to their original positions. At this time, the rotating gear 28 will continue to drive the gear bar 7 and the screen 19 to rise after rotating one circle. The screen 19 continuously repeats the rising and falling operations to achieve the purpose of simulating the vibration of the screen 19. At this time, the vibration of the screen 19 will screen the activated carbon on the screen 19. At this time, the finished product discharged from the discharge device 3 will not be mixed with raw material fragments, thereby avoiding the problem that the finished activated carbon product will be mixed with some raw material fragments and cause the quality of the product to decline, so that the quality of the finished product is not affected.

[0027] The upper surfaces of the two movable plates 12 are fixedly connected with lifting columns 8, and both ends of the discharging device 3 are fixedly connected with fixed frames 9. The two fixed frames 9 correspond to the positions of the two limit grooves 15. The upper surfaces of the two fixed frames 9 are penetrated with grooves 11, and both ends of the discharging device 3 are provided with gear bars 7. The lower surfaces of the two lifting columns 8 pass through the grooves 11 and are fixedly connected with the lower surfaces of the corresponding gear bars 7. The opposite sides of the two gear bars 7 are meshed with rotating gears 28. The grooves 11 on the two fixed frames 9 will resist the two lifting columns 8, so that the two rotating gears 28 can only move in the vertical direction when driving the gear bar 7 and the lifting column 8 to move, avoiding the problem that the lifting column 8 is offset and the rotating gear 28 and the gear bar 7 cannot be accurately meshed, thereby improving the stability of the lifting column 8 and the gear bar 7 during lifting.

[0028] The two rotating gears 28 are fixedly connected with a connecting short rod 1 26, and the front and rear ends of the two connecting short rods 26 are rotatably connected with a connecting plate 1 21, and the lower surface of each connecting plate 21 is fixedly connected to the upper surface of the discharging device 3, and the two connecting short rods 26 are fixedly connected with a rotating bevel gear 29, and the opposite ends of the two rotating bevel gears 29 are vertically meshed with a meshing bevel gear 2 30, and a long rod 6 is arranged between the two meshing bevel gears 2 30, and the two ends of the long rod 6 are fixedly connected with the meshing bevel gear 2 30, and the lower end position of the moving short rod 16 is always located inside the fixed plate 14, so the moving short rod 16 plays a limiting role when the screen 19 simulates vibration, and when the two moving plates 12 drive the screen 19 to vibrate, the problem that the two moving plates 12 may be offset due to excessively high vibration frequency is avoided, and since the lower end position of the moving short rod 16 is always located inside the fixed plate 14, the two moving plates 12 can also only move vertically.

[0029] Both ends of the two long rods 6 are provided with connecting plates 2 31, the lower surfaces of the two connecting plates 2 31 are fixedly connected to the upper surface of the discharging device 3, the right surfaces of the two connecting plates 2 31 are penetrated with holes 32, and the two connecting plates 2 31 are rotatably connected to the long rod 6 through the holes 32, and the rear surface of the connecting plate 1 21 at the left rear end is penetrated with a hole 27 corresponding to the position of the connecting short rod 1 26, and the rear surface of the connecting plate 1 21 at the left rear end is fixedly connected with a fixing ring 25 corresponding to the position of the hole 27, and the rear surface of the fixing ring 25 is fixedly connected with a motor 5, and the output port of the motor 5 passes through the hole 27 and the rear of the connecting short rod 1 26 at the left end. The surface is fixedly connected. When the discharge device 3 on the grinding body 1 needs to be cleaned, the motor 5 is started and the long rod 6 is rotated. At this time, the meshing bevel gear 33 on the long rod 6 will also rotate. The meshing bevel gear 33 will drive the rotating bevel gear 22 and the connecting short rod 2 34 to rotate. At this time, the connecting short rod 2 34 will drive the rotating gear 23. Since the rotating gear 23 is meshed with the gear ring 20, the gear ring 20 will drive the two cleaning scrapers 17 to clean the deeper inner wall of the discharge device 3, which avoids the higher interior of the discharge device 3 causing the staff to be unable to touch the deeper inner wall of the discharge device 3 during manual cleaning, thereby improving the cleaning effect.

[0030] The right end of the long rod 6 is fixedly connected with a meshing bevel gear 33, and the lower end of the meshing bevel gear 33 is vertically meshed with a rotating bevel gear 22. The lower surface of the rotating bevel gear 22 is fixedly connected with a connecting short rod 24. A hole 10 is penetrated through the upper surface of the discharging device 3, and the connecting short rod 24 is rotatably connected to the inner wall of the discharging device 3 through the hole 10. A rotating gear 23 is arranged inside the discharging device 3, and the lower surface of the connecting short rod 24 is fixedly connected to the upper surface of the rotating gear 23. When the motor 5 starts to drive the screen 19 to vibrate, the cleaning scraper 17 will also be linked to rotate along the inner wall of the discharging device 3. At this time, the cleaning scraper 17 will scratch the activated carbon product attached to the inner wall, so that the attached activated carbon product falls back onto the screen 19, avoiding that some products will be attached to the inner wall of the discharging device 3 and cannot fall, so that the output is not affected.

[0031] The inner wall of the discharging device 3 is rotatably connected with a gear ring 20, and the lower surface of the gear ring 20 is fixedly connected with two cleaning scrapers 17. The gear ring 20 is meshingly connected with a rotating gear 23. Since limiting grooves 15 are provided at both ends of the discharging device 3 on the grinding body 1, part of the activated carbon will overflow from the two limiting grooves 15 when the material is discharged from the discharging port, and the fixed frame 9 will cover the two limiting grooves 15 to prevent the activated carbon from overflowing from the two limiting grooves 15 and causing pollution to the environment.

[0032] Working principle: In the first step, when the activated carbon falls from the discharging device 3, it will first pass through the screen 19. At this time, the motor 5 is started, and the motor 5 drives the left connecting short rod 1 26 to rotate. At this time, the rotating bevel gear 2 29 on the left drives the corresponding meshing bevel gear 2 30 to rotate. At this time, the long rod 6 will start to rotate, and the long rod 6 will drive the two rotating bevel gears 29 and the two connecting short rods 1 26 to rotate synchronously. The two connecting short rods 1 26 will drive the rotating gear 2 28 to rotate. There are only one-quarter teeth on the rotating gear 28, so the rotating gear 2 When the rotating gear 28 is engaged with the two gear bars 7, the rotation will drive the two gear bars 7 and the two lifting columns 8 to rise. When the lifting columns 8 rise, the two moving plates 12 and the screen 19 will be driven to rise. At this time, the two springs 13 are stretched. When the rotating gear 28 cancels the engagement with the gear bar 7, the spring 13 rebounds and drives the gear bar 7 and the screen 19 to the original position. At this time, the rotating gear 28 will continue to drive the gear bar 7 and the screen 19 to rise after rotating one circle. The screen 19 continuously repeats the rising and falling operations to achieve the purpose of simulating the vibration of the screen 19 At this time, the vibration of the screen 19 will screen the activated carbon on the screen 19. At this time, the finished product exported from the discharge device 3 will not be mixed with raw material fragments, avoiding the problem that the activated carbon finished product will be mixed with some raw material fragments and cause the quality of the product to decline, so that the quality of the finished product is not affected. The grooves 11 on the two fixed frames 9 will resist the two lifting columns 8, so that the two rotating gears 28 can only move in the vertical direction when driving the gear bar 7 and the lifting column 8 to move, avoiding the problem that the lifting column 8 is offset and the rotating gear 28 and the gear bar 7 cannot be accurately meshed, improving the stability of the lifting column 8 and the gear bar 7 during lifting and lowering, the lower end position of the moving short rod 16 is always located inside the fixed plate 14, so the moving short rod 16 plays a limiting role when the screen 19 simulates vibration, when the two moving plates 12 drive the screen 19 to vibrate, it avoids the problem that the two moving plates 12 may cause position deviation due to excessively high vibration frequency, because the lower end position of the moving short rod 16 is always inside the fixed plate 14, so the two moving plates 12 can also only move vertically.

[0033] In the second step, when it is necessary to clean the discharge device 3 on the grinding body 1, start the motor 5 and the long rod 6 rotates. At this time, the meshing bevel gear 33 on the long rod 6 will also rotate. The meshing bevel gear 33 will drive the rotating bevel gear 22 and the connecting short rod 2 34 to rotate. At this time, the connecting short rod 2 34 will drive the rotating gear 23. Since the rotating gear 23 is meshed with the gear ring 20, the gear ring 20 will drive the two cleaning scrapers 17 to clean the deeper inner wall of the discharge device 3, which avoids the higher interior of the discharge device 3 causing the staff to be unable to touch the deeper inner wall of the discharge device 3 during manual cleaning, thereby improving the cleaning effect.

[0034] In the third step, when the motor 5 starts to drive the screen 19 to vibrate, it will also link the cleaning scraper 17 to rotate along the inner wall of the discharge device 3. At this time, the cleaning scraper 17 will scratch the activated carbon products attached to the inner wall, so that the attached activated carbon products fall back onto the screen 19, avoiding that some products will be attached to the inner wall of the discharge device 3 and unable to fall, so that the output is not affected. Since the limiting grooves 15 are set at both ends of the discharge device 3 on the grinding body 1, part of the activated carbon will overflow from the two limiting grooves 15 when the discharge port is unloaded, and the fixed frame 9 will cover the two limiting grooves 15 to avoid the activated carbon overflowing from the two limiting grooves 15 and causing pollution to the environment.

Many modifications and variations will be apparent to those of ordinary skill in the art.
