Description

Technical Field

[0001] This utility model belongs to the technical field of pulverizing devices, specifically relating to a pulverizing device for activated carbon production and processing. Background Technology

[0002] Activated carbon is amorphous carbon that has undergone activation treatment. It is available in powder, granular, or pellet form and has strong adsorption capacity. The activation treatment removes various oils and impurities from the surface of the amorphous carbon, increasing its pore number, surface area, and surface activity, thereby enabling it to adsorb many gases, liquids, or certain solutes in solutions.

[0003] In the production and processing of activated carbon, a pulverizing device is required to crush the activated carbon into related products. However, existing activated carbon pulverizing devices typically cannot automatically re-crush the under-crushed activated carbon. This requires manual re-feeding of the under-crushed activated carbon, leading to repetitive feeding operations and increased workload for workers, hindering practical application. Therefore, there is an urgent need for a pulverizing device for activated carbon production and processing.

[0004] A patent with publication number CN215353658U discloses a high-efficiency pulverizing device for activated carbon production and processing. The device includes a feeding box, a drive motor, feeding rollers, a feeding shaft, drive belt A, drive belt B, a crushing roller, a grinding roller, a screening plate, a vibrating motor, a discharge pipe, and a slag discharge pipe. In use, activated carbon is poured into the feeding box, and the drive motor is started. The output shaft of the drive motor drives the feeding rollers and the feeding shaft to rotate. With the assistance of drive belts A and B, the crushing roller and the grinding roller rotate synchronously, thereby feeding, crushing, and grinding the activated carbon. The pulverized activated carbon falls onto the screening plate, and the vibrating motor is started simultaneously. Carbon that meets the screening requirements is discharged through the discharge pipe, while carbon that does not meet the screening requirements is discharged through the slag discharge pipe.

[0005] However, the above solution cannot automatically re-crush activated carbon that does not meet the screening requirements. Workers need to pour the activated carbon that does not meet the screening requirements back into the feeding box for crushing, which makes workers repeat the feeding operation, increasing the workload of workers and making it inconvenient for practical promotion and use.

[0039] A reflux assembly is installed inside the crushing box 1 by means of an elastic element for limiting and sliding. The reflux assembly is in drive cooperation with the screening plate 30. A reflux channel 35 is provided at the lower end of the reflux assembly, and the reflux channel 35 is in drive communication with the screening plate 30.

[0040] The reflux assembly includes a guide cover 7. The guide cover 7 is slidably installed through the side wall of the crushing box 1 in a horizontal direction. A movable plate 33 is fixedly installed at one end of the guide cover 7 inside the crushing box 1. The screening plate 30 is in transmission cooperation with the movable plate 33.

[0041] A screw conveyor 32 is rotatably installed inside the guide cover 7. A first servo motor 8 is fixedly installed on the top of the guide cover 7. The output shaft of the first servo motor 8 is coaxially and fixedly connected to the top of the screw conveyor 32. An extension plate 15 is fixedly connected to the higher end of the guide cover 7, and the extension plate 15 faces the feed inlet of the crushing box 1.

[0042] The elastic element includes a first guide rod 4, which is slidably and horizontally inserted through the inner wall of the crushing box 1. One end of the first guide rod 4 inside the crushing box 1 is fixedly connected to the movable plate 33. A third spring 34 is sleeved on the outer surface of the first guide rod 4. One end of the third spring 34 is fixedly connected to the movable plate 33, and the other end is fixedly connected to the inner wall of the crushing box 1.

[0043] Working principle: Initial state as follows Figure 4 As shown, the screening plate 30 is tilted upwards at this time, and the sealing plate 27 does not block the discharge port.

[0044] When in use, the staff put the activated carbon to be crushed into the feed port at the top of the crushing box 1.

[0045] During this process, the second servo motor 11 is started, and the output shaft of the second servo motor 11 drives the first crushing roller 10 to rotate. In turn, the meshing of the first gear 16 and the second gear 17 drives the second crushing roller 9 to rotate in the opposite direction, thereby crushing the activated carbon.

[0046] At the same time, as the second gear 17 rotates, it will also drive the fourth pulley 19 to rotate with the help of the third pulley 18 and the belt, thereby driving the grinding roller 26 to rotate, so as to grind the pulverized activated carbon.

[0047] The ground activated carbon falls onto the surface of the sieve plate 30, allowing the activated carbon that meets the sieving requirements to fall directly into the collection box 31, while the activated carbon that does not meet the sieving requirements rolls and accumulates on the left side of the sieve plate 30 (see reference). Figure 4 (location in the middle)

[0048] When activated carbon on the surface of the sieve plate 30 that does not meet the sieve requirements needs to be crushed again, the third servo motor 13 and the first servo motor 8 are started.

[0049] The output shaft of the third servo motor 13 drives the connecting rod 25 and the slider 23 to rotate. The slider 23 pushes the disk 3 to rotate via the second spring 21. The disk 3 drives the sealing plate 27 to rotate via the second shaft 28, thereby sealing the discharge port. After the sealing plate 27 seals the discharge port, the limiting hole 22 is aligned with the limiting rod on the surface of the limiting plate 5. At this time, the limiting rod will be inserted into the limiting hole 22 under the elastic action of the first spring 6, thereby limiting the disk 3. Subsequently, as the connecting rod 25 continues to rotate, the disk 3 and the sealing plate 27 stop rotating, and the slider 23 will slide in the groove and compress the second spring 21.

[0050] At the same time, during the rotation of the connecting rod 25, the first pulley 14 will be driven to rotate with the help of the second pulley 24 and the transmission belt, thereby driving the first shaft 29 and the screening plate 30 to rotate.

[0051] As the screening plate 30 rotates, it pushes the movable plate 33 and the guide cover 7 to slide and compress the third spring 34 until the screening plate 30 rotates to a horizontal state (it should be noted that when the screening plate 30 rotates to a horizontal state, the sealing plate 27 just rotates to block the discharge port). After the screening plate 30 rotates to a horizontal state, as the rotation continues, the screening plate 30 gradually rotates to a tilted downward state. The movable plate 33 and the guide cover 7 will reset under the elastic action of the third spring 34 to ensure that the movable plate 33 always abuts against the edge of the screening plate 30 until the screening plate 30 is connected to the return channel 35.

[0052] When the screening plate 30 is connected to the return channel 35, activated carbon that does not meet the screening requirements on the screening plate 30 will roll into the guide shroud 7. The output shaft of the first servo motor 8 drives the auger 32 to rotate, thereby guiding the activated carbon that does not meet the screening requirements that has rolled into the guide shroud 7 back into the crushing box 1 through the auger 32 and the extension plate 15 for re-crushing. This ensures the crushing quality, avoids repetitive manual work, reduces the labor intensity of workers, and is more conducive to practical promotion and use.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
