Description

Technical Field

[0001] This invention relates to the field of wood product processing equipment technology, specifically to a centralized dust treatment device for wood product processing. Background Art

[0002] Wood processing generates a large amount of sawdust. If the sawdust is not treated in a timely manner, it will pose certain environmental hazards. Therefore, a centralized dust treatment device for wood processing workshops is needed.

[0003] Patent application number 202320516618.8 relates to a centralized dust treatment device for wood product processing. This device includes a three-way control valve connected to the space above a first and second filter chamber via two output pipes. The first and second filter chambers have identical structures. A bag-connecting valve is installed at the top of the second filter chamber, and the lower part of the valve is connected to a bag-connecting seat. A dust collector bag is installed on the bag-connecting seat. When replacing or maintaining the bag filter, the filter in the adjacent filter chamber can be opened by controlling the valve's opening and closing, allowing replacement without stopping the machine or in a non-working state. Simultaneously, the user, wearing a protective mask, enters the enclosed filter chamber to replace the filter, minimizing dust pollution to the external environment. However, this device struggles to filter, separate, and collect mixed sawdust and wood dust. Therefore, a centralized dust treatment device for wood product processing is proposed to address the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a centralized dust treatment device for wood product processing, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a centralized dust treatment device for wood product processing, including a dust cover, a feeding box fixedly connected to the bottom of the dust cover, a motor fixedly connected to the rear of the dust cover, a ventilation pipe fixedly connected to the right side of the dust cover, a lower dust box fixedly connected to the right side of the ventilation pipe, a dust collection box fixedly connected to the bottom of the lower dust box, a double rotating wheel rotatably connected to the front of the dust cover, a large rotating wheel connected to the surface of the double rotating wheel via belt drive, a chip collection box rotatably connected to the rear of the large rotating wheel, and a small rotating wheel rotatably connected to the surface of the double rotating wheel via belt drive; a separation mechanism is provided on the left side of the dust cover, a crushing mechanism is provided inside the chip collection box, and a squeezing mechanism is provided inside the dust collection box; the separation mechanism includes a feeding box, an inclined conveyor belt, a gravity wheel, a mounting frame, a transmission belt assembly, a reciprocating screw, a reciprocating brush, and a filter plate. The inclined conveyor belt is fixedly connected to the inner wall of the dust cover, the feeding box is fixedly connected to the top of the inclined conveyor belt, the gravity wheel is fixedly connected to the front of the inclined conveyor belt, the mounting frame is fixedly connected to the top of the inclined conveyor belt, the transmission belt assembly is rotatably connected to the front of the inclined conveyor belt, the reciprocating screw is fixedly connected to the output end of the motor, the reciprocating brush is slidably connected to the surface of the reciprocating screw, the right side of the dust cover is fixedly connected to the left side of the ventilation pipe, the right side of the ventilation pipe is fixedly connected to the left side of the lower dust box, the bottom of the lower dust box is fixedly connected to the top of the dust collection box, the rear of the mounting frame is fixedly connected to the front of the filter plate, and the left side of the reciprocating brush is in contact with the right side of the filter plate.

This achieves the effect of separating and collecting wood chips and wood dust separately, improving collection efficiency.

[0006] Preferably, the crushing mechanism includes an inclined conveyor belt II, a rotating rod, and crushing blades. The inclined conveyor belt II is fixedly connected to the bottom of the feed box, the rotating rod is rotatably connected to the inner wall of the chip collection box, and the crushing blades are fixedly connected to the surface of the rotating rod.

The surface of the crushing blades after movement contacts the top of the linkage plate, and the bottom of the trigger rod after movement contacts the top of the discharge plate. This allows the larger wood chips separated to be crushed and discharged simultaneously, reducing their mass and volume for easier collection.

[0025] Working principle: When the device is processing wood dust, the motor 3 is started, and the collected waste dust is poured into the feeding box 1101, causing the waste dust to fall onto the surface of the inclined conveyor belt 1102. At this time, the motor 3 drives the reciprocating screw 1106 to rotate, which in turn drives the transmission belt assembly 1105 to rotate. The transmission belt assembly 1105 drives the inclined conveyor belt 1102 to transport the waste dust, and the rotation of the gravity wheel 1103 generates vibration, causing the waste dust to vibrate and separate during transportation. At this time, the suction fan is started, and the suction force sucks up the wood dust that has been vibrated and bounced up, passing it through the ventilation pipe 4 to the lower dust box 5, where it falls into the dust collection box 6. Since some wood chips are also relatively light, when the lighter wood chips are also... When sucked up, the wood chips are blocked on the surface of the filter plate 1108 and fall down. At the same time, the reciprocating screw 1106 drives the reciprocating brush 1107 to clean the surface of the filter plate 1108, brushing off the accumulated wood dust that clogs the filter holes, maintaining working efficiency. The wood chips fall into the feed box 2 and are conveyed to the surface of the inclined conveyor belt 1201, and finally fall into the chip collection box 7. At this time, the double rotating wheel 8 drives the large rotating wheel 9 to rotate through the belt, causing the rotating rod 1202 to rotate and drive the crushing blade 1203 to crush the wood chips, making the wood chips smaller in mass and volume, and thus easier to collect. At the same time, the crushing blade 1203 collides with the linkage plate 1204 during its rotation, causing the linkage to... Plate 1204 drives trigger rod 1206 to strike discharge plate 1207 downwards, causing discharge plate 1207 to open. When crushing blade 1203 leaves the surface of linkage plate 1204, discharge plate 1207 loses pressure and rises back to its original position via spring. This achieves the effect of reciprocating opening and closing to discharge wood chips while crushing them. When the wood dust falls into dust collection box 6, double rotor 8 drives small rotor 10, causing T-shaped rod 1301 to reciprocate through connecting rod on the surface of small rotor 10. At the same time, T-shaped rod 1301 drives connecting plate 1302 to reciprocate. Connecting plate 1302 drives impact hammer rod 1303 to strike the inner wall of dust collection box 6, causing the wood dust adhering to the inner wall of dust collection box 6 to be dispersed. The dust is shaken off, thus keeping the dust collection box 6 clean. At the same time, the horizontal extrusion plate 1304 is driven to horizontally extrude the accumulated and shaken wood dust, releasing the storage space inside the dust collection box 6. The horizontal extrusion plate 1304 drives the round-headed guide rod 1305 to move into the guide groove of the guide block 1306, causing the guide block 1306 to separate and slide away from each other along the sliding groove opened on the inner wall of the dust collection box 6. The guide block 1306 drives the vertical push plate 1307 to vertically push the dust, so that the wood dust at the bottom of the dust collection box 6 can be cleaned from multiple directions horizontally and vertically, thereby increasing the storage space and extruding the wood dust into blocks to avoid secondary dust pollution when dumping wood dust waste laterally.
