Description

Technical Field

[0001] This invention relates to the field of wood processing technology, specifically to a dust treatment device for a wood processing workshop. Background Technology

[0002] Wood processing, using wood as raw material, primarily employs mechanical or chemical methods to process it, ensuring that the finished product retains the basic characteristics of wood. Wood possesses advantages such as light weight, high strength-to-weight ratio, good elasticity, impact resistance, rich and beautiful grain and color patterns, and ease of processing. However, wood processing generates sawdust, chipping, and sanding dust. This dust not only increases wear and tear on wood processing equipment and affects the normal operation of electrical appliances but also poses significant hazards to the environment and human health. Therefore, wood processing workshops need to be equipped with dust control devices to manage the dust and debris generated during wood processing.

[0003] According to Chinese Patent Application No. CN202223595440.5, a dust treatment device for a wood processing workshop is provided. It is equipped with a pressure plate, a hydraulic cylinder and a collection component. When wood chips are fed into the treatment box, they fall to the upper surface of the bottom plate. After the hydraulic cylinder is activated, its push rod end drives the pressure plate to move downward. The pressure plate compresses the wood chips, thereby compressing the volume of the wood chips, reducing the space occupied by the wood chip dust, and the compacted wood chips are also easier to transport.

[0004] When the above-mentioned device is in use, dust and debris are directly sucked into the treatment box for compression without dust suppression. The dust still floats in the treatment box. In the prior art, the dust in the gas is filtered before being released, but some dust still floats into the air with the released gas. Therefore, a dust treatment device for wood processing workshops is proposed to solve the above-mentioned problems. Summary of the Invention

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This dust treatment device for a wood processing workshop, through a dust suppression mechanism and a filter assembly, uses a water spray pipe to spray water from a water tank into the tank to suppress dust. At the same time, a rotating dispersing plate disperses the water, increasing the atomization effect of the water and promoting contact with dust in the air, further improving the dust suppression effect. Meanwhile, a guide plate changes the angle of the airflow, guiding it to contact the rotating dispersing plate to ensure the dispersing efficiency of the plate. A filter screen is used to filter the air and dust-laden water droplets, further improving the dust suppression effect and solving the problems of incomplete dust treatment and easy dispersion in traditional devices.

[0015] 2. This dust treatment device for a wood processing workshop utilizes a cleaning mechanism. An arc-shaped top block pushes a circular plate, causing a hinged plate to swing around a fixed rod. The hinged plate, through a sliding hole, moves a sliding rod and a connecting plate, pulling the filter screen plate left and right. Simultaneously, under the elastic force of a tension spring, the filter screen plate shakes left and right, shaking off surface dust and cleaning simultaneously to prevent filter clogging and facilitate the exhaust of air after dust suppression. While the filter screen plate slides, a scraper removes residual dust clumps, preventing filter clogging and facilitating the filtration of dust-laden water droplets. The shaking of the filter screen plate enhances the cleaning effect, ensuring that the filtered water after dust suppression collects at the bottom of the chamber. A return pipe then pumps the filtered water back to the water tank, achieving water resource recycling, reducing waste, preventing excessive water accumulation from affecting equipment operation, reducing water consumption, meeting green production requirements, and simplifying the drainage process.

[0016] 3. This dust treatment device for a wood processing workshop, through the setting of a rotating rod, a connecting rod, and a hinged arm, uses the hinged arm to drive the air guide plate and the connecting rod to finely adjust the angle around the rotating rod, thereby changing the air guide angle of the inverted "V" shaped air guide plate, improving the contact efficiency of dust and water mist under different working conditions, and optimizing the dust reduction effect.

[0017] 4. This dust treatment device for a wood processing workshop, through the installation of a hinged arm and a baffle plate, uses the hinged arm to pull the rack and pinion gear to rotate the rotating shaft and turntable. The turntable drives the sliding rod to push the connecting rod through the sliding sleeve, so that the connecting rod drives the mounting plate and the baffle plate to swing around the fixed rod, adjusting the airflow direction at the dust suction pipe outlet and adapting to the change in the angle of the guide plate, so that dust and debris are evenly distributed in the box, ensuring that the incoming air and water mist are fully mixed, and further improving the dust reduction efficiency.

[0024] Please see Figure 1-9One embodiment of the present invention is a dust treatment device for a wood processing workshop, comprising a housing 1, an exhaust fan 2 connected to the right side of the housing 1, a suction pipe 3 connected to the left side of the housing 1, and a suction hood 4 connected to the left end of the suction pipe 3. By activating the exhaust fan 2, dust-laden air is drawn into the housing 1 through the suction pipe 3 and the suction hood 4. A dust-suppressing mechanism 5 is provided inside the housing 1 to suppress the dust drawn into the housing 1. A filter assembly 8 is provided inside the housing 1, located to the right of the dust-suppressing mechanism 5, for filtering dust. A cleaning mechanism 6 is provided inside the housing 1 for cleaning the filter assembly 8. The dust-suppressing mechanism 5 includes a water tank 5. 1. A water pump 52, a water spray pipe 53, a rotating shaft 54, a water tank 51, and a water pump 52 are all installed on the top of the housing 1. The water spray pipe 53 is fixedly connected to the front and rear sides of the inner wall of the housing 1, and the outlet of the water pump 52 is connected to the water spray pipe 53 through a pipe. Several nozzles are provided at the bottom of the water spray pipe 53. The filter assembly 8 includes a filter screen plate 81, which is set on the inner wall of the housing 1 for filtering impurities. The housing 1 is L-shaped, and the filter screen plate 81 is slidably connected to the inner wall of the L-shaped side of the housing 1. Multiple tension springs 82 are connected between the right side of the filter screen plate 81 and the housing 1 for pulling the filter screen plate 81 to the right. The bottom of the filter screen plate 81 is... A support rod 83 is connected, and the bottom of the support rod 83 is slidably connected to a movable groove opened on the inner wall of the bottom of the box 1 to support the filter plate 81. The filter plate 81 is L-shaped, and one side slides on the right side of the L-shape of the box 1. The longitudinal side of the L-shape of the filter plate 81 is used to separate moisture and dust in the gas, and the transverse side of the L-shape of the filter plate 81 is used to separate impurities in the wastewater, improving the comprehensiveness of dust treatment. The rotating shaft 54 ​​is rotatably connected to the inner wall of the box 1 through a bearing. Multiple dispersing plates 55 are circumferentially connected at equal intervals on the outer wall of the rotating shaft 54 ​​to disperse airflow and water droplets. The inner wall of the box 1 is provided with an air guide plate 56. The 6 is arranged in an inverted "V" shape to guide the airflow upward to contact the dispersing plate 55. Water from the water tank 51 is sprayed into the housing 1 by the water spray pipe 53, thereby reducing dust. At the same time, the rotating dispersing plate 55 disperses the water, expanding the atomization effect of the water, thereby promoting contact with dust in the air and further improving the dust reduction effect. Meanwhile, the air guide plate 56 changes the angle of the upward airflow, guiding it to contact the rotating dispersing plate 55 to ensure the dispersing efficiency of the dispersing plate 55. The filter plate 81 filters the air and dust-laden water droplets, further improving the dust reduction effect and solving the problems of incomplete dust treatment and easy dispersion in traditional devices.

[0025] The cleaning mechanism 6 includes: a fixed rod 61, an arc-shaped top block 65, and a connecting plate 67. The fixed rod 61 is fixedly connected to the inner wall of the back of the housing 1. A hinge plate 62 is rotatably connected to the front of the outer wall of the fixed rod 61. A spring 63 is connected between the right side of the hinge plate 62 and the housing 1. There are multiple arc-shaped top blocks 65, which are respectively connected to the side of each dispersing plate 55 away from the rotating shaft 54. A circular plate 64 is connected to the left end of the hinge plate 62, and the circular plate 64 abuts against the arc-shaped top block 65 to push the hinge plate 62 to deflect around the fixed rod 61. A sliding hole 66 is opened on the front of the hinge plate 62 and is located at... Below the fixed rod 61, a sliding rod 68 is slidably connected to the inner wall of the sliding hole 66, and a connecting plate 67 is fixedly connected to the back of the sliding rod 68. The right side of the connecting plate 67 is connected to the filter screen plate 81, which is used to pull the filter screen plate 81 to move to the left. The arc-shaped top block 65 pushes the round plate 64 to make the hinge plate 62 swing around the fixed rod 61. The hinge plate 62 drives the sliding rod 68 and the connecting plate 67 to move through the sliding hole 66 and pull the filter screen plate 81 to slide left and right. At the same time, under the elastic force of the tension spring 82, the filter screen plate 81 shakes left and right to shake off the surface dust, cleaning simultaneously to avoid filter clogging and facilitate the exhaust of air after dust removal.

[0026] Working principle: By starting the exhaust fan 2, dust from the workshop is drawn into the housing 1 through the dust hood 4 and the dust suction pipe 3. Water is pumped from the water tank 51 to the spray pipe 53 by the water pump 52, and sprayed through the nozzles, combining with the dust to form dust-laden water droplets. Simultaneously, the inverted "V"-shaped air guide plate 56 changes the airflow direction, guiding the airflow to disperse and prolonging the contact time between dust and water droplets. An external motor drives the rotating shaft 54 ​​to rotate the dispersing plate 55, further dispersing the airflow and water droplets, enhancing the contact efficiency between dust and water. The dispersing plate 55 also prevents the water droplets from being drawn back down during their fall. The tilt of the fan 2 further prolongs the contact time between dust and water droplets. Dust-laden water droplets fall onto the filter plate 81, and the water flows down through the filter screen, while the dust is intercepted. When the dispersing plate 55 rotates, it drives the arc-shaped top block 65 to rotate. The arc-shaped top block 65 pushes the circular plate 64, causing the hinge plate 62 to swing and intermittently compress the spring 63. The hinge plate 62 drives the slide rod 68 to move through the sliding hole 66. The slide rod 68 drives the connecting plate 67 to move and pulls the filter plate 81 to slide left and right. Under the elastic force of the tension spring 82, the filter plate 81 shakes left and right to shake off the surface dust, cleaning simultaneously to avoid filter clogging.

[0027] Please see Figure 1-9Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 6 further includes: a plurality of scrapers 69, which are fixedly connected at equal intervals to the front and rear sides of the inner wall of the housing 1, and the bottom of the scrapers 69 is in contact with the upper surface of the filter screen plate 81, for cleaning impurities on the L-shaped transverse side of the filter screen plate 81. When the filter screen plate 81 slides, the scrapers 69 scrape off residual dust clumps to prevent the filter screen holes from clogging and facilitate the filtration of dust-laden water droplets. The vibration of the filter screen plate 81 enhances the cleaning effect and ensures that the filtered water after dust settling collects at the bottom of the housing 1; a triangular stop 610 is fixedly connected to the left inner wall of the housing 1, and the bottom of the triangular stop 610 is in contact with the upper surface of the filter screen plate 81, for covering the gap between the left side of the filter screen plate 81 and the housing 1; a sealing baffle 611 is installed on the back of the housing 1 and is located on the back of the filter screen plate 81. A sealing gasket is provided between the sealing baffle 611 and the housing 1 to discharge impurities from the housing 1 and the filter screen 81. By opening the sealing baffle 611, the accumulated debris on the filter screen 81 can be directly and deeply cleaned, facilitating the discharge of impurities, improving equipment maintenance efficiency, and ensuring long-term use. A second water pump 612 is installed on the right side of the housing 1. The input end of the second water pump 612 is connected to the lower right side of the housing 1 through a pipe. The output end of the second water pump 612 is connected to a return pipe 613. The end of the return pipe 613 away from the second water pump 612 is connected to the water tank 51 for circulating the filtered water. The filtered water in the housing 1 is pumped back to the water tank 51 through the return pipe 613, realizing water resource recycling, reducing waste, avoiding excessive water accumulation that affects equipment operation, reducing water consumption, meeting the requirements of green production, and simplifying the drainage process.

[0028] The housing 1 is equipped with an airflow adjustment mechanism 7, which includes a rotating rod 71. The rotating rod 71 is rotatably connected to the inner wall of the housing 1 via a bearing and is located on the inner arc of the air guide plate 56. Two connecting rods 72 are connected to the outer wall of the rotating rod 71. The other ends of the two connecting rods 72 are fixedly connected to the inner arc of the air guide plate 56. The lower right side of the air guide plate 56 is hinged to the left side of the hinge plate 62 via a hinge arm 73, which is used to deflect the air guide plate 56 around the rotating rod 71 to change the airflow direction. The hinge arm 73 drives the air guide plate 56 and the connecting rods 72 to make slight adjustments to the angle around the rotating rod 71, thereby changing the airflow angle of the inverted "V" shaped air guide plate 56, improving the contact efficiency of dust and water mist under different working conditions, and optimizing the dust reduction effect.

[0029] Working principle: When the filter plate 81 slides, several sets of equally spaced scrapers 69 adhere to its surface, scraping away residual dust clumps to prevent filter screen clogging. The vibration of the filter plate 81 enhances the cleaning effect, ensuring that the filtered water after dust suppression collects at the bottom of the housing 1. By starting the water pump 612, the water accumulated at the bottom of the housing 1 is pumped back to the water tank 51 through the return pipe 613, realizing water resource recycling and reducing waste. By opening the sealing baffle 611, the debris accumulated on the filter plate 81 can be directly deep-cleaned, improving equipment maintenance efficiency. When the hinge plate 62 swings, the hinge arm 73 drives the air guide plate 56 and the connecting rod 72 to adjust the angle around the rotating rod 71, changing the air guide angle of the inverted "V" shaped air guide plate 56, improving the contact efficiency between dust and water mist under different working conditions, and optimizing the dust suppression effect.

[0030] Please see Figure 1-9 Based on the above embodiments, in another embodiment of the present invention, the wind direction adjustment mechanism 7 further includes: a mounting frame 74, a second rotating shaft 79, and a rack 714. The mounting frame 74 is connected to the left inner wall of the housing 1. A second fixing rod 75 is connected to the mounting frame 74. Two second mounting plates 76 are movably sleeved on the outer wall of the second fixing rod 75. A wind deflector 77 is connected between the two second mounting plates 76 and is close to the right end of the suction pipe 3. A connecting rod 78 is connected to the bottom of the lower second mounting plate 76. The second rotating shaft 79 is rotatably connected to the left inner wall of the housing 1 through a bearing. A turntable 710 is connected to the right end of the second rotating shaft 79. A second sliding rod 711 is inserted into the right side of the turntable 710. A sliding sleeve 712 is connected to the right end of the sliding rod 711, and the sliding sleeve 712 is slidably connected to the outer wall of the second connecting rod 78. The rack 714... 14 slides up and down in the groove opened on the left inner wall of the box 1. The bottom of the rack 714 is hinged to the second hinge arm 715. The bottom end of the second hinge arm 715 is hinged to the left side of the air guide plate 56. The outer wall of the second rotating shaft 79 is fixedly fitted with a gear 713, and the rack 714 meshes with the gear 713. The second hinge arm 715 pulls the rack 714 to mesh with the gear 713, so that the second rotating shaft 79 and the turntable 710 rotate. The turntable 710 drives the second sliding rod 711 to push the second connecting rod 78 through the sliding sleeve 712, so that the second connecting rod 78 drives the second mounting plate 76 and the wind baffle 77 to swing around the second fixed rod 75, adjust the airflow direction of the dust suction pipe 3 outlet, adapt to the change of the angle of the air guide plate 56, so that the dust and debris are evenly distributed in the box 1, ensuring that the incoming air and water mist are fully mixed, and further improving the dust reduction efficiency.

[0031] Working principle: When the air guide plate 56 swings, the rack 714 is driven to slide along the slide groove through the hinge arm 715. The rack 714 meshes with the gear 713 to make the rotating shaft 79 and the turntable 710 rotate. The turntable 710 drives the eccentric sliding rod 711 to rotate. At the same time, the sliding rod 711 pushes the connecting rod 78 through the sliding sleeve 712. The connecting rod 78 drives the mounting plate 76 and the baffle plate 77 to swing around the fixed rod 75, adjusting the airflow direction of the dust suction pipe 3 outlet and adapting to the angle change of the air guide plate 56, so that dust and debris are evenly distributed in the box 1, ensuring that the incoming air and water mist are fully mixed.
