DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] A grinding device for producing activated carbon, comprising a body 1, a feed port 2 is arranged on the top of the body 1, a grinding mechanism is arranged inside the body 1, a screen 3 is arranged below the grinding mechanism through a reciprocating mechanism, a discharge port 4 is arranged at the bottom of the body 1, the discharge port 4 is arranged at the bottom of the screen 3, and a cleaning mechanism is arranged on the surface of the screen 3;

[0027] The reciprocating mechanism includes a base plate 5, a first motor 6, a cam 7, a telescopic rod 8, a spring 9 and a claw 10. The claw 10 is fixed to the side of the screen 3. One end of the screen 3 is fixedly connected to the inner wall of the body 1 through the telescopic rod 8. The base plate 5 is fixed to the inner wall of the body 1. The cam 7 rotates on the top of the base plate 5. The first motor 6 is installed at the bottom of the base plate 5 and is connected to the cam 7. The cam 7 cooperates with the claw 10. The spring 9 is sleeved on the surface of the telescopic rod 8 and fixed between the body 1 and the screen 3.

[0028] See also Figure 1 , 2 And 3, the first motor 6 can drive the cam 7 to rotate unidirectionally, and the cam 7 can periodically pull the claw 10 when rotating, so that the claw 10 pulls the screen 3 to move in the direction close to the cam 7. At this time, the other end of the screen 3 will stretch the telescopic rod 8 and cause the spring 9 to deform and store energy. As the cam 7 continues to rotate, the claw 10 will detach from the surface of the cam 7, and the spring 9 can drive the screen 3 to reset through the telescopic rod 8 under the action of its own elastic force, thereby causing the screen 3 to move in the direction away from the cam 7 until it is reset.

[0029] The cleaning mechanism includes a driving wheel 11, a swing arm 12 and a brush 13, one of the driving wheels 11 rotates on the surface of the body 1, and the other driving wheel 11 is coaxially fixed to the top of the cam 7. Both ends of the swing arm 12 are eccentrically hinged to the tops of the two driving wheels 11. The brush 13 is fixed to the bottom of the swing arm 12 and contacts the screen 3. A guide plate 14 is welded to the inner wall of the body 1, and the guide plate 14 is inclined. One of the driving wheels 11 is rotatably set at the bottom of the guide plate 14.

[0030] See also Figure 4 When the cam 7 rotates, it can drive the driving wheel 11 to rotate synchronously. Since one end of the swing arm 12 is eccentrically hinged on the driving wheel 11, the driving wheel 11 can drive one end of the swing arm 12 to swing continuously when it rotates in one direction. When both ends of the swing arm 12 move in this way, the swing arm 12 as a whole will perform a crank-connecting rod movement, thereby forming a cleaning area with a rectangular middle and semicircular ends on the screen 3, thereby cleaning the clogged mesh of the screen 3.

[0031] The grinding mechanism includes a second motor 15, a rotating shaft 16, a spiral blade 17 and a filter cartridge 18. The second motor 15 is fixed to the side of the machine body 1. The rotating shaft 16 is rotatably arranged in the machine body 1 and is connected to the output end of the second motor 15. The filter cartridge 18 and the spiral blade 17 are both fixed on the rotating shaft 16. The outer edge of the spiral blade 17 is in contact with the filter cartridge 18 and the inner wall of the machine body 1.

[0032] See also Figure 2The second motor 15 can drive the rotating shaft 16 to rotate, and the rotating shaft 16 can drive the spiral blade 17 to rotate inside the filter cartridge 18. The diameter of the through hole on the curved surface of the filter cartridge 18 is smaller than the diameter of the through hole on the plane. When the activated carbon enters the body 1 through the feed port 2, the spiral blade 17 will crush the activated carbon and continuously send it into the filter screen. After being screened by the curved surface of the filter cartridge 18, it falls onto the screen 3 for screening again.

[0033] Embodiment 2:

[0034] In the above scheme, the activated carbon is ground by the grinding mechanism. However, in the process of the activated carbon moving from the feed port 2 to one end of the filter cartridge 18, it is inevitable that there will be some large particles of activated carbon that are difficult to grind. Therefore, a crushing mechanism is provided in this embodiment, so that these activated carbons can enter the large particle crushing chamber 19 through the filter cartridge 18 under the drive of the spiral blade 17. The large particle crushing chamber 19 is provided inside the body 1, and the crushing mechanism is provided at the bottom of the large particle crushing chamber 19. The crushing mechanism includes a crushing drum 20, a gear 21 and a drive shaft 22. The drive shaft 22 is fixed to the axis of the crushing drum 20, and the crushing drum 20 is rotatably arranged on the inner wall of the large particle crushing chamber 19 through the driving shaft 22. One end of the driving shaft 22 passes through the machine body 1 and extends to the outside. The two gears 21 are respectively keyed to the two driving shafts 22 and mesh with each other. One of the driving shafts 22 is connected to the rotating shaft 16 through a synchronous member. The synchronous member includes a synchronous belt 23 and a synchronous wheel 24. The two synchronous wheels 24 are respectively fixed on the rotating shaft 16 and one of the driving shafts 22. The two synchronous wheels 24 are connected by a synchronous belt 23.

[0035] See also Figure 1 and 2 Some large particles of activated carbon that are difficult to grind will fall onto the two crushing rollers 20 under the action of gravity after entering the large particle crushing chamber 19. The rotating shaft 16 can drive one of the driving shafts 22 to rotate through the synchronous wheel 24 and the synchronous belt 23. The driving shaft 22 can simultaneously drive the two crushing rollers 20 to rotate through two mutually meshing gears 21, so that the two crushing rollers 20 can crush this part of large particles of activated carbon. The crushed large particles of activated carbon can be directly discharged from the discharge port 4.

[0036] Working principle: When in use, the activated carbon is introduced into the machine body 1 from the feed port 2, and then the second motor 15 and the first motor 6 are started. The second motor 15 can drive the rotating shaft 16 to rotate, and the rotating shaft 16 can drive the spiral blade 17 to rotate inside the filter cartridge 18. The spiral blade 17 can crush the activated carbon and continuously send it into the filter screen, and it will be screened through the holes on the surface of the filter cartridge 18 and fall onto the screen 3 for screening again. The first motor 6 can drive the cam 7 to rotate unidirectionally, and the cam 7 can periodically pull the claw 10 when rotating, so as to make The claw 10 pulls the screen 3 to move towards the direction close to the cam 7. At this time, the other end of the screen 3 will lengthen the telescopic rod 8 and cause the spring 9 to deform and store energy. As the cam 7 continues to rotate, the claw 10 will detach from the surface of the cam 7. Under the action of its own elastic force, the spring 9 can drive the screen 3 to reset through the telescopic rod 8, thereby realizing the horizontal reciprocating motion of the screen 3, which can not only increase the contact area between the screen 3 and the activated carbon, but also make the reciprocating motion of the screen 3 vibrate, and cooperate with the brush 13 to clean the mesh of the screen 3 to improve the cleaning effect of the screen 3.
