A dust removal device for biological particle processing

Abstract

This utility model discloses a dust removal device for biomass pellet processing, including a cleaning structure installed on the side surface of the dust collector, a vibration structure for cleaning the cleaning structure, and a conveying structure. Through the cleaning structure, a baffle moves upward on the surface of the conveying structure. When the baffle touches the roller, it pulls the roller, connecting plate, slider, and brush upward, compressing the first spring. As the connecting plate slides upward, the brush cleans the mesh of the filter screen. With continuous conveying, after the baffle moves away from below the roller, the return force of the first spring pulls the slider and connecting plate downward to reset. This process continues until the baffle reaches the roller position for the next rotation, continuing to clean the filter screen upward. This effectively prevents filter clogging, improves dust removal efficiency and equipment continuity during biomass pellet processing, thereby ensuring production efficiency and product quality.

Description

Technical Field

[0001] This utility model relates to the field of bioparticle processing technology, and in particular to a dust removal device for bioparticle processing. Background Technology

[0002] Biomass pellet processing refers to the physical compression of agricultural and forestry waste such as sawdust, rice husks, and straw into renewable energy pellets with a certain shape, density, and size without the addition of any binders. Due to their high calorific value, low pollution, and renewability, these pellets are often used as biomass fuels and are widely used in fields such as home heating, industrial boilers, and power generation.

[0003] In the current bio-particle processing industry, dust removal devices are indispensable environmental protection equipment. Their main function is to capture and remove dust generated during processing to ensure a clean working environment and product quality. However, existing dust removal devices face certain technical challenges in application: their surfaces are usually equipped with filter screens designed to intercept larger particles and prevent them from entering the dust removal device and affecting its performance. However, over time, the mesh of these filter screens is easily clogged by dust and impurities, leading to a decrease in filtration efficiency and an increase in the flow resistance of the entire dust removal system. In severe cases, this can even cause the device to become blocked. This situation not only reduces the processing efficiency of bio-particles but may also adversely affect the quality of the final product. Utility Model Content

[0004] One objective of this invention is to provide a dust removal device for bioparticle processing. This invention addresses the problem mentioned in the background that the mesh of the filter screen is easily clogged by dust and impurities, leading to a decrease in filtration efficiency and an increase in the flow resistance of the entire dust removal system. In severe cases, it can even cause the device to become blocked. This situation not only reduces the processing efficiency of bioparticles but may also adversely affect the quality of the final product.

[0005] A dust removal device for bioparticle processing according to an embodiment of the present invention includes a cleaning structure installed on the side surface of a dust collector, a vibration structure for cleaning the cleaning structure, and a conveying structure. A filter screen is installed on the surface of the dust collector. The cleaning structure includes a connecting plate and a baffle. A slider is slidably connected to the side surface of the dust collector; two sets of sliders are provided. The connecting plate is movably connected to the side surface of the dust collector via the sliders. A telescopic rod and a second spring are provided between the connecting plate and the sliders. Brush bristles are fixedly connected to the inner surface of the connecting plate. The baffle is fixedly connected to the outer surface of the conveying structure. The vibration structure includes a roller and a triangular protrusion. The triangular protrusion is fixedly connected to the outer surface of the conveying structure, and the roller is rotatably connected to the surface of the connecting plate.

[0006] Preferably, the surface of the dust collector is provided with a sliding groove, and a sliding rod is fixedly connected inside the sliding groove, with the slider slidably connected to the surface of the sliding rod.

[0007] Preferably, a first spring is provided between the upper surface of the slider and the inner wall of the groove to realize the downward reset of the cleaning structure.

[0008] Preferably, the rollers are provided in two sets, and the two sets of rollers are respectively rotatably connected to both ends of the connecting plate near the conveying structure.

[0009] Preferably, two sets of the triangular protrusions and the stop bars are provided, and the two sets of the stop bars and triangular protrusions are respectively fixedly connected to the two ends of the surface of the conveying structure, and a number of triangular protrusions are provided in one set.

[0010] Preferably, the dust collector has an internal disassembly structure, which includes a rotating wheel and a filter screen groove, the filter screen groove being located on the upper surface of the dust collector.

[0011] Preferably, the filter screen is movably connected inside the filter screen groove, and the side surface of the filter screen has a plurality of toothed grooves.

[0012] Preferably, a rotating wheel is rotatably connected to the upper inner part of the filter screen groove, and a toothed block is fixedly connected to the side surface of the rotating wheel, with the toothed block and the toothed groove meshing with each other.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a cleaning structure to absorb dust from bio-particles during the conveying process. The dust is then filtered through a filter screen. During conveying, a baffle moves upwards on the conveyor structure's surface. When the baffle touches the roller, it pulls the roller, connecting plate, slider, and brush upwards, compressing the first spring. As the connecting plate slides upwards, the brush cleans the filter screen's mesh. With continued conveying, after the baffle moves away from the roller, the first spring's return force pulls the slider and connecting plate downwards to reset. This process continues until the baffle reaches the roller's position on the next rotation, continuing to clean the filter screen. This effectively prevents filter clogging, improves dust removal efficiency and equipment continuity during bio-particle processing, and thus ensures production efficiency and product quality.

[0015] This invention utilizes a vibration structure. During the continuous conveying of biological particles by the conveying structure, triangular protrusions on the surface of the conveying structure continuously collide with the rollers. When the tips of the triangular protrusions touch the rollers, the rollers and connecting plates move towards the slider, compressing the second spring and telescopic rod. When the rollers reach the recessed part of the triangular protrusions, the second spring and telescopic rod reset, causing the connecting plate to pop out in the opposite direction of the slider. Through the arrangement of several sets of triangular protrusions, the connecting plate vibrates continuously, thereby cleaning the biological particle dust adhering to the brush surface. This effectively reduces the accumulation of biological particle dust, maintains the cleaning efficiency of the filter screen, extends the service life of the equipment, and reduces the maintenance frequency.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-5A dust removal device for biomass pellet processing includes a cleaning structure 4 installed on the side surface of a dust collector 2, a vibration structure 6 for cleaning the cleaning structure 4, and a conveying structure 1. A filter screen 3 is installed on the surface of the dust collector 2. The cleaning structure 4 includes a connecting plate 407 and a baffle 409. Two sliders 403 are slidably connected to the side surface of the dust collector 2. The connecting plate 407 is movably connected to the side surface of the dust collector 2 via the sliders 403. A telescopic rod 405 and a second spring 406 are provided between the connecting plate 407 and the sliders 403. Brush bristles 408 are fixedly connected to the inner surface of the connecting plate 407. The up-and-down sliding of the brush bristles 408 cleans the mesh openings on the surface of the filter screen 3. 409 is fixedly connected to the outer surface of the conveying structure 1. The vibration structure 6 includes a roller 601 and a triangular protrusion 602. The triangular protrusion 602 is fixedly connected to the outer surface of the conveying structure 1, and the roller 601 is rotatably connected to the surface of the connecting plate 407. During the bioparticle processing, when the bioparticles are conveyed through the conveying structure 1, the dust collector 2 absorbs the dust from the bioparticles, and the filter screen 3 filters the dust from the particles. During the conveying process through the conveying structure 1, the stop lever 409 moves upward on the surface of the conveying structure 1. When the stop lever 409 touches the roller 601, it drives the roller 601, the connecting plate 407, the slider 403, and the brush bristles 408 upward. The first spring 404 is compressed. During the upward sliding of the connecting plate 407, the brush bristles 408 clean the mesh of the filter screen 3. As the conveying structure 1 continues to convey the particles, after the stop bar 409 moves away from below the roller 601, the return force of the first spring 404 drives the slider 403 and the connecting plate 407 downward to reset. This continues until the stop bar 409 reaches the position of the roller 601 in the next rotation, then continues to clean the filter screen 3 upward. This effectively prevents the filter screen 3 from clogging, improves the dust removal efficiency and equipment operation continuity during the bio-particle processing, thereby ensuring production efficiency and product quality. During the continuous conveying of bio-particles by the conveying structure 1, the triangular protrusions 602 on the surface of the conveying structure 1... The roller 601 is continuously struck. When the tip of the triangular protrusion 602 touches the roller 601, the roller 601 and the connecting plate 407 move toward the slider 403. The second spring 406 and the telescopic rod 405 are squeezed. When the roller 601 reaches the recessed part of the triangular protrusion 602, the second spring 406 and the telescopic rod 405 reset and pop the connecting plate 407 toward the opposite direction of the slider 403. Through the setting of several sets of triangular protrusions 602, the connecting plate 407 vibrates continuously, thereby cleaning the biological particulate dust adhering to the surface of the bristles 408, effectively reducing the accumulation of biological particulate dust, maintaining the cleaning efficiency of the filter screen 3, extending the service life of the equipment and reducing the maintenance frequency.

[0025] Example 1: A groove 401 is provided on the surface of the dust collector 2. A sliding rod 402 is fixedly connected inside the groove 401. A slider 403 is slidably connected to the surface of the sliding rod 402, so that the slider 403 can slide up and down inside the groove 401. A first spring 404 is provided between the upper surface of the slider 403 and the inner wall of the groove 401 to realize the downward reset of the cleaning structure 4. Two sets of rollers 601 are provided. The two sets of rollers 601 are rotatably connected to the two ends of the connecting plate 407 near the conveying structure 1. Two sets of triangular protrusions 602 and two sets of stop bars 409 are provided. The two sets of stop bars 409 and triangular protrusions 602 are fixedly connected to the two ends of the surface of the conveying structure 1. A set of triangular protrusions 602 is provided with several. The several triangular protrusions 602 continuously collide with the rollers 601, so that the connecting plate 407 achieves horizontal vibration, and cleans the biological particles and dust on the surface of the bristles 408.

[0026] Example 2: The dust collector 2 is equipped with a disassembly structure 5, which includes a rotating wheel 502 and a filter screen groove 504. The filter screen groove 504 is located on the upper surface of the dust collector 2. The filter screen 3 is movably connected inside the filter screen groove 504. The side surface of the filter screen 3 is provided with several toothed grooves 501. The rotating wheel 502 is rotatably connected to the upper part of the filter screen groove 504. The side surface of the rotating wheel 502 is fixedly connected with toothed blocks 503. The toothed blocks 503 and the toothed grooves 501 mesh with each other. When it is necessary to disassemble, inspect, or replace the filter screen 3, the rotating wheel 502 rotates clockwise, and the rotating wheel 502 slides the filter screen 3 upward through the toothed blocks 503 and the toothed grooves 501 until it slides out of the filter screen groove 504, making the disassembly process of the filter screen 3 more convenient.

[0027] In use, during the bio-particle processing, the conveying structure 1 continuously conveys the bio-particles, while the dust collector 2 absorbs the generated particulate dust. A filter screen 3 is installed on the surface of the dust collector 2 to filter particulate dust. As the conveying structure 1 moves, the stop bar 409 fixed to the outer surface of the conveying structure 1 moves upward and touches the roller 601. At this time, the roller 601, the connecting plate 407, and the connected slider 403 and brush 408 are driven upward. The first spring 404 is compressed. During the upward movement of the connecting plate 407, the brush 408 cleans the mesh of the filter screen 3 to prevent clogging. When the stop bar 409 leaves below the roller 601, the return force of the first spring 404 drives the slider 403 and the connecting plate 407 downward to reset, awaiting the arrival of the next stop bar 409. The cleaning process continues, and before the stop lever 409 touches the roller 601, the triangular protrusion 602 on the surface of the conveying structure 1 continuously collides with the roller 601. When the tip of the triangular protrusion 602 touches the roller 601, the roller 601 and the connecting plate 407 move towards the slider 403, squeezing the second spring 406 and the telescopic rod 405. When the roller 601 reaches the recessed part of the triangular protrusion 602, the second spring 406 and the telescopic rod 405 reset, causing the connecting plate 407 to pop out in the opposite direction towards the slider 403, thus achieving continuous vibration of the connecting plate 407. This cleans the biological particles and dust adhering to the surface of the brush bristles 408. The disassembly structure 5 makes the replacement and maintenance of the filter screen 3 more convenient. Through this series of actions, the device effectively improves the dust removal efficiency and the continuity of equipment operation, ensuring production efficiency and product quality.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
