Description

Technical Field

[0001] This utility model relates to the field of grinding machinery technology, specifically to a grinding mechanism for activated carbon processing. Background Technology

[0002] Activated carbon, due to its well-developed pore structure, large specific surface area, and smooth surface, is widely used in water purification, gas phase adsorption, solvent filtration, gas desulfurization, petroleum catalytic reforming, and other fields. However, activated carbon needs to be ground into powder during production and processing, so developing a grinding mechanism for activated carbon processing is particularly important.

[0003] A grinding device for activated carbon processing, as described in reference announcement number CN209631404U, includes a maintenance device and a filtration device. The maintenance device comprises a grinding mill body with an integrally formed maintenance groove on its surface. A sealing groove is formed on one side of the maintenance groove relative to the interior of the grinding mill body, and a sliding maintenance door groove is formed on the side of the maintenance groove opposite to the sealing groove. A connecting spring is connected inside the sliding maintenance door groove. This maintenance device, designed on the surface of the grinding mill body, facilitates timely troubleshooting by maintenance personnel when a malfunction occurs. Troubleshooting and maintenance effectively improve the work efficiency of maintenance personnel and prevent external dust from entering the main body of the grinding mill due to forgetting to close the sliding maintenance door. The filter device designed on the outside of the grinding mill body makes it easy for staff to filter out non-standard activated carbon powder and collect it for secondary processing, which effectively improves product quality. As can be seen from the above, although the device can be used well, it is usually not convenient to inject activated carbon material into the grinding mill body at a predetermined rate, which makes the feeding process of the grinding mechanism somewhat inconvenient and often troubles users. Utility Model Content

[0004] The purpose of this invention is to provide a grinding mechanism for activated carbon processing, in order to solve the problem that although the device proposed in the background art can be applied well, it is usually inconvenient to inject activated carbon material into the grinding mill body at a predetermined rate, which makes the feeding process of the grinding mechanism inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding mechanism for activated carbon processing, comprising a frame, a machine platform at the top of the frame, a positioning seat on one side of the top of the machine platform, a support frame on the outer wall of one side of the machine platform, a grinding chamber at the top of the support frame, a shaft cylinder on the outer wall of the grinding chamber near the positioning seat, a storage hopper at the top of the grinding chamber, a discharge port on the inner wall at the lower end of the storage hopper, limiting frames on the outer walls of the storage hopper on both sides of the discharge port, a baffle slidably connected to the outer wall of the storage hopper between the limiting frames, a hexagonal nut on the outer wall at the upper end of the baffle, a limiting bolt installed on the internal thread of the hexagonal nut, one end of the limiting bolt extending to the outside of the hexagonal nut, and the other end of the limiting bolt penetrating the baffle and abutting against the outer wall of the storage hopper.

[0006] Preferably, a movable frame is rotatably mounted on the outer wall of one side of the grinding chamber, and a circular door is installed at the end of the movable frame away from the grinding chamber. The inner wall of the circular door contacts the outer wall of the grinding chamber, so that the grinding chamber can be opened and closed.

[0007] Preferably, a guide hopper is provided on the outer wall of the circular box door, and the bottom end of the guide hopper is connected to the outer wall of the circular box door. The guide hopper is provided to guide the activated carbon material into the grinding box.

[0008] Preferably, a pull plate is installed on the outer wall of the circular box door on one side of the feed hopper, and a nut seat is provided on the outer wall of the grinding box on the side of the pull plate away from the feed hopper. A locking bolt is threaded on the outer wall of the pull plate, and one end of the locking bolt passes through the pull plate and is threadedly connected to the nut seat. By passing one end of the locking bolt through the pull plate and screwing it into the nut seat, the circular box door is locked and placed on the outer wall of the grinding box.

[0009] Preferably, the inner wall of the grinding chamber is provided with an inner grinding ring, the inner side of the inner grinding ring is provided with a turntable, and a plurality of grinding blocks are installed on the outer wall of the turntable. The outer wall of the grinding blocks contacts the inner wall of the inner grinding ring. By setting the grinding blocks, the activated carbon material is ground on the inner wall of the inner grinding ring.

[0010] Preferably, a motor is installed at the top of the positioning seat, and a rotating shaft is installed at the output end of the motor through a coupling. The end of the rotating shaft away from the motor passes through a shaft cylinder and is connected to the outer surface of the turntable. The motor is configured so that the turntable can be driven to rotate via the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the grinding mechanism for activated carbon processing not only achieves the purpose of automatically feeding activated carbon material at a predetermined rate to improve the convenience of feeding the grinding mechanism, but also achieves the purpose of easy maintenance of the grinding mechanism, and achieves the purpose of automating the grinding of activated carbon.

[0012] (1) By loosening the limit bolt, the baffle located inside the limit frame slides up and down to adjust the opening and closing size of the discharge port. Then, tighten the limit bolt to position the baffle on the outer wall of the storage hopper. Since the activated carbon material is injected and stored in the storage hopper, the activated carbon material inside the storage hopper can fall into the guide hopper at a predetermined rate and fall into the grinding box. This achieves the purpose of automatically feeding the activated carbon material at a predetermined rate, thereby improving the convenience of feeding the grinding mechanism.

[0013] (2) By tightening the locking bolt, one end of the locking bolt is screwed out to the outside of the nut seat. Then, the pull plate is pulled so that the circular box door rotates on the outer wall of the grinding box via the movable frame, so that the circular box door is rotated away from the outer surface of the grinding box. At this time, the opening on the outer surface of the grinding box is in an open and closed state, so as to facilitate the cleaning and maintenance of the inner side of the grinding box, thereby achieving the purpose of convenient maintenance of the grinding mechanism.

[0014] (3) By injecting activated carbon material into the grinding box, and then starting the motor, the motor drives the turntable to rotate via the rotating shaft, and the turntable drives several grinding blocks to rotate. Since the outer wall of the grinding block is in contact with the inner wall of the inner grinding ring, the grinding block can grind the activated carbon material on the inner wall of the inner grinding ring. The small particles of powdered activated carbon after grinding fall into the bottom of the grinding box through the filter holes on the inner grinding ring and are discharged by the support frame. The powdered activated carbon can be collected by simply placing the collection box under the support frame, thereby achieving the purpose of automating the grinding of activated carbon.
