Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf threshing technology, specifically to a conveyor belt conveyor for removing air from the threshing and re-drying compartments. Background Technology

[0002] The air separator discharge belt conveyor is a common material conveying equipment in the leaf threshing and re-drying process. It is used in conjunction with the air separator to output the sorted tobacco leaves from the air separator and send them to the downstream process.

[0003] In the tobacco leaf re-drying process, dust is easily generated when the air-distribution bin discharge belt conveyor transports dusty tobacco leaves to the end for discharge. Existing air-distribution bin discharge belt conveyors control dust by installing a dust collector hood above the discharge port and a dust collection plate below, with suction at the discharge port. However, these methods only passively remove or collect dust thrown out with the tobacco leaves, offering limited dust removal efficiency. Furthermore, they cannot actively remove residual dust from the belt, resulting in a large amount of dust falling and accumulating on the dust collection plate during belt movement. This poses a potential safety hazard if dust is not cleaned promptly from the dust collection plate and enters the transmission mechanism of the air-distribution bin discharge belt conveyor. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the existing technology by providing a dust removal device for a leaf re-drying air-compartment discharge conveyor belt.

[0005] The present invention adopts the following technical solution to solve the technical problem: a dust removal device for a leaf re-baking air-compartment discharge conveyor belt, wherein a dust receiving plate is provided at the discharge port of the discharge conveyor belt and attached to the bottom of the belt of the discharge conveyor belt, and the dust receiving plate has a cavity inside and an opening at the top; It also includes a dust-sweeping structure comprising a brush plate, brush bristles, and a scraper; the brush plate is installed and fixed to the opening of the dust-receiving plate, and the scraper is fixed on it, with the brush bristles densely arranged on its top; the brush bristles and the scraper are arranged sequentially along the movement direction of the bottom of the belt, and the top of both are in contact with the bottom of the belt.

[0006] Furthermore, an air inlet and an air outlet are respectively opened at both ends of the bottom of the ash receiving plate, and the air outlet is connected to the negative pressure device through a flexible hose.

[0007] Furthermore, an air replenishment plate is rotatably installed on the ash receiving plate corresponding to the air inlet; The air supply plate and the ash receiving plate form a rotating pair that supports the air supply plate to rotate and close to completely cover the air inlet or to rotate and open to completely expose the air inlet.

[0008] Furthermore, the top of both ends of the ash receiving plate is symmetrically provided with recessed mounting grooves, and both ends of the brush plate are embedded in the mounting grooves and fixed to the ash receiving plate.

[0009] Furthermore, the brush plate is detachably installed and fixed to the ash receiving plate by adjusting bolts.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] A dust removal device for a leaf re-drying air-discharge conveyor belt, such as Figures 1-2 As shown, its structural relationship is as follows: the ash receiving plate 1 is set at the discharge port of the discharge belt conveyor and attached to the bottom of the belt of the discharge belt conveyor. The ash receiving plate 1 has a cavity inside and an opening at the top. It also includes a dust removal structure 2 comprising a brush plate 21, brush bristles 22 and scraper 23; the brush plate 21 is installed and fixed to the opening of the dust receiving plate 1, and a scraper 23 is installed and fixed on it, and the top of the brush plate 21 is densely covered with brush bristles 22; the brush bristles 22 and scraper 23 are arranged sequentially along the movement direction of the bottom of the belt, and the top of both are in contact with the bottom of the belt.

[0023] Preferably, an air inlet 12 and an air outlet 13 are respectively opened at both ends of the bottom of the ash receiving plate 1, and the air outlet 13 is connected to the negative pressure device through a flexible hose.

[0024] Preferably, an air supply plate 14 is rotatably installed on the ash receiving plate 1 corresponding to the air inlet 12; A rotating pair of air supply plates 14 and ash receiving plates 1 is formed between them, which supports the air supply plate 14 to rotate and close to completely cover the air inlet 12 or to rotate and open to completely expose the air inlet 12.

[0025] Rotating the adjustment air supply plate 14 can adjust the air intake at the air inlet 12 accordingly, thereby adjusting the suction of the negative pressure device and effectively removing dust under different working conditions.

[0026] Preferably, recessed mounting grooves 11 are symmetrically provided at the top of both ends of the ash receiving plate 1, and both ends of the brush plate 21 are embedded in the mounting grooves 11 and fixed to the ash receiving plate 1.

[0027] Preferably, the brush plate 21 is detachably installed and fixed to the ash receiving plate 1 by adjusting bolts 24.

[0028] Preferably, the adjusting bolt 24 passes through the bottom of the mounting groove 11, through the ash receiving plate 1, and is threadedly connected to the ash receiving plate 1 and the brush plate 21.

[0029] Preferably, the ash receiving plate 1 has a structure in which the distance between the front and rear sides decreases from top to bottom, with the larger side at the top and the smaller side at the bottom.

[0030] Preferably, the hose is a polyurethane copper-plated steel wire industrial vacuum cleaner hose.

[0031] Preferably, the mounting groove 11 is located at the middle of the end face of the ash receiving plate 1.

[0032] The dust removal device for the leaf re-drying air-discharge conveyor belt described above is used to clean the bottom of the conveyor belt at the discharge port of the air-discharge conveyor belt, including the following process: The first step is to rotate and adjust the opening of the air supply plate 14 until the air inlet 12 has a suitable air intake volume.

[0033] The second step is to rotate the adjusting bolt 24 so that the brush plate 21 drives the bristles 22 and scraper 23 installed on it to rise or fall until the top of the bristles 22 and scraper 23 just makes good contact with the bottom of the belt.

[0034] The third step is to start the negative pressure device and the air-discharge conveyor belt. When the belt with debris and dust is moving over the dust removal device, it keeps in contact with the brush bristles 22 and the scraper 23. First, the brush bristles 22 brush off the larger debris and dust on the belt, and then the scraper further cleans the fine dust on the belt. The debris and dust that are separated from the belt fall and are collected in the dust collection plate 1, and are discharged through the hose under the action of the negative pressure device.

[0035] In the third step above, the installation height of the brush plate 21 should be adjusted in a timely manner according to the wear and tear of the bristles 22 and the scraper 23, as described in the second step, so as to continuously ensure good contact between the bristles 22 and the scraper 23 and the bottom of the belt.
