Description

Technical Field

[0001] This utility model relates to the field of activated carbon production technology, specifically to an activated carbon air separation and impurity removal device. Background Technology

[0002] Activated carbon is a black, porous solid carbonaceous material produced from coal through crushing, molding, or carbonization and activation of uniform coal particles. It has strong adsorption properties and is a widely used industrial adsorbent. However, many impurities are mixed in during the processing of activated carbon, and air separation equipment is usually used to remove lighter impurities.

[0003] A search revealed an activated carbon air-classification and impurity removal device, as disclosed in application number 202221967552.6, which belongs to the field of impurity removal equipment, specifically an activated carbon air-classification and impurity removal device. This device includes an impurity removal box with a discharge port at the bottom and a feed hopper at the top. A filter frame is located on one side of the box and is connected to it via a detachable structure. A drive motor is fixedly installed on the other side of the box, with its output shaft extending into the box and fitted with blower blades. A connecting plate is fixedly installed on one inner wall of the box, and a transmission shaft is rotatably mounted on the connecting plate. A transmission mechanism connects the drive motor and the transmission shaft. Two baffles are slidably installed on the top of the box, and a drive mechanism connects the transmission shaft and the corresponding baffles. In this invention, the reciprocating movement of the two baffles increases the gap and increases the discharge capacity of the feed hopper, thereby enabling thorough impurity removal from the activated carbon.

[0004] However, the above method still has the following drawbacks in actual use: it uses a single blower blade for air separation and impurity removal. During the process of feeding activated carbon, the air separation effect of activated carbon particles far away from the blower blade decreases, resulting in incomplete air separation and impurity removal. Furthermore, under the action of the blower blade, the position of activated carbon is prone to shift, and some activated carbon cannot enter the discharge port and is left inside the impurity removal box, which is not convenient for collection. Utility Model Content

[0005] The purpose of this invention is to provide an activated carbon air classifier for removing impurities, which has the advantages of good impurity removal effect and easy material feeding.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an activated carbon air separation and impurity removal device, comprising a body, ventilation slots provided on the top of both sides of the body, an air inlet pipe corresponding to the ventilation slot on the top of one side of the body, and an exhaust pipe corresponding to the ventilation slot on the top of the other side of the body, an exhaust fan provided inside the air inlet pipe and the exhaust pipe, a filter plate embedded at the end of the exhaust pipe away from the body, and a collection slot corresponding to the filter plate at the bottom of the exhaust pipe, an inclined ventilation box provided inside the body, and the ventilation box moving up and down, a ventilation plate embedded on the surface of the ventilation box, and a blower communicating with the ventilation box on the side of the body.

[0008] A further feature of this invention is that the machine body has a corresponding inclined discharge trough on the side that is inclined downward near the ventilation box, and a discharge pipe is fixedly provided on one side of the discharge trough.

[0010] A further feature of this invention is that a collection box corresponding to the collection trough is provided below the exhaust pipe, and a fixing frame is provided at the top of the collection box. The fixing frame is connected to the bottom of the exhaust pipe by fixing screws.

[0011] A further feature of this invention is that a positioning frame is fixedly provided on the inner wall of the ventilation box, the ventilation plate is disposed at the top of the positioning frame, and the ventilation plate is connected to the positioning frame by screws, with the surface of the ventilation plate and the top of the ventilation box being on the same plane.

[0012] A further feature of this invention is that: a guide post is fixedly provided at the bottom of the ventilation box, a support plate is fixedly provided at the bottom of the guide post, a guide plate that is slidably connected to the guide post is fixedly provided on the inner wall of the body, and a support spring sleeved on the outside of the guide post is provided between the guide plate and the support plate.

[0014] In summary, this utility model has the following beneficial effects: The exhaust fan, installed inside the air inlet and outlet pipes with the same airflow direction, can perform preliminary air separation on the activated carbon being fed, allowing impurities to be discharged through the exhaust pipe and collected in the impurity collection box. Simultaneously, the ventilation box is elastically set up and down; under the action of gravity, when the activated carbon falls onto the surface of the ventilation plate, it bounces up and down. Furthermore, under the action of the blower, external air is evenly discharged through the ventilation holes of the ventilation plate, allowing impurities adhering to the surface of the activated carbon to be further discharged through the exhaust pipe, thus improving the impurity removal effect of the activated carbon.

[0027] In this embodiment, preferably, the air inlet pipe 2 and the air outlet pipe 3 are both fixedly provided with mounting frames at the ends near the body 1. The mounting frames are connected to the side of the body 1 by mounting screws, which facilitates quick assembly and disassembly of the air inlet pipe 2 and the air outlet pipe 3. The end of the air inlet pipe 2 away from the body 1 is provided with a dustproof plate 201. The surface of the dustproof plate 201 is provided with multiple dustproof holes, which play a role in preventing dust in the air. The dustproof plate 201 is connected to the air inlet pipe 2 by screws, which facilitates assembly and disassembly of the dustproof plate 201.

[0028] In this embodiment, preferably, a collection box 303 corresponding to the collection trough 302 is provided below the exhaust pipe 3. The impurities filtered out are collected through the collection box 303. A fixing frame 304 is provided at the top of the collection box 303. The fixing frame 304 is connected to the bottom of the exhaust pipe 3 by fixing screws, which facilitates quick assembly and disassembly of the collection box 303.

[0029] In this embodiment, preferably, a positioning frame 401 is fixedly provided on the inner wall of the ventilation box 4, and a ventilation plate 402 is provided on the top of the positioning frame 401. The ventilation plate 402 is connected to the positioning frame 401 by screws, which facilitates the quick assembly and disassembly of the ventilation plate 402. The surface of the ventilation plate 402 is on the same plane as the top of the ventilation box 4, so as to guide the activated carbon after impurity removal and make it easy to discharge.

[0030] In this embodiment, preferably, a guide post 404 is fixedly provided at the bottom of the ventilation box 4, and a support plate 405 is fixedly provided at the bottom of the guide post 404. A guide plate 403 that is slidably connected to the guide post 404 is fixedly provided on the inner wall of the body 1, which plays a guiding and limiting role in the movement of the ventilation box 4. A support spring 406 sleeved on the outside of the guide post 404 is provided between the guide plate 403 and the support plate 405. The support spring 406 can make the ventilation box 4 vibrate up and down, and make the activated carbon on the surface of the ventilation plate 402 jump up and down, so as to separate the attached dust.

[0031] In this embodiment, preferably, a ventilation pipe 407 communicating with the ventilation box 4 is fixedly provided at the bottom end of the ventilation box 4, and the ventilation pipe 407 is slidably connected to the bottom end of the body 1.

A dustproof net is provided at the air inlet end of the blower 5 to prevent the blower 5 from blowing dust in the outside air into the interior of the body 1.

[0032] In operation, first, start the two exhaust fans. The activated carbon to be separated is added to the air separation chamber of the machine body 1 through the feed hopper 103. The exhaust fan inside the air inlet pipe 2 blows lighter impurities from the activated carbon towards the exhaust pipe 3. The exhaust fan in the exhaust pipe 3 discharges the impurities to the outside, where they are blocked by the filter plate 301 and allowed to pass through the impurity collection trough 302 into the impurity collection box 303 for collection. The activated carbon after preliminary air separation falls onto the surface of the ventilation plate 402, where it is further dispersed by the elasticity of the support spring 406. The air plate 402 vibrates, causing the activated carbon on its surface to bounce up and down, and the blower 5 is activated. The blower 5 blows the outside air into the ventilation box 4 and discharges it evenly through the ventilation holes on the surface of the air plate 402, so that the dust attached to the surface of the activated carbon is separated and the dust flows towards the exhaust pipe 3, so that it enters the interior of the exhaust pipe 3 for further air separation of impurities. The air separated activated carbon enters the interior of the discharge pipe 106 through the discharge chute 105 and is discharged through the discharge pipe 106 for collection.
