Description

Technical Field

[0001] This invention relates to the field of environmental dust removal technology, specifically to an environmental dust removal device used in furniture processing. Background Technology

[0002] The environmentally friendly dust removal equipment for furniture processing is a dry two-stage combined dust removal equipment, specifically designed for wood dust. It takes into account three core needs: environmental compliance, wood chip drying and resource recycling, and safe production. Unlike wet dust removal (which generates wastewater and waste wood chips), it realizes the recycling of dust and belongs to the category of circular environmentally friendly dust removal devices. Dust removal is required during furniture processing. To ensure that the exhaust gas meets environmental standards while collecting dry and clean wood chips and dust, and to achieve resource recycling and reuse of dust, the dust-laden gas is generally passed through a cyclone separator to separate and collect coarse wood shavings and large wood chips. Then, the airflow containing fine dust is introduced into a pulse jet filter cartridge dust collector for purification before being discharged. Since the filter material on the surface of the cartridge is mostly made of polyester non-woven fabric with many pleats, when the gas containing fine wood chips passes through the filter cartridge, the wood chip dust easily accumulates deep in the pleats and penetrates into the fibers of the filter material. This makes it difficult for the subsequent pulse jet airflow to remove the dust accumulated deep in the pleats, affecting the smoothness of the gas passing through the filter cartridge and reducing the dust removal efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an environmentally friendly dust removal device for furniture processing, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an environmentally friendly dust removal device for furniture processing, comprising a main body, a pulse gas tank fixedly connected to the top of the main body, the output end of the pulse gas tank being located inside the main body, and further comprising: The limiting mechanism is installed inside the main body to improve the removal rate of impurities when the pulse gas tank is working. The limiting mechanism includes a fixing frame installed inside the main body, with a fixing rod fixedly connected to the bottom of the fixing frame; The push component is installed on the outer surface of the fixed rod; The actuating assembly includes three limiting plates fixedly connected to the outer surface of the fixed rod, with a conical ring fixedly connected to the end of each limiting plate away from the fixed rod.

[0005] Furthermore, the main body includes: Dust removal components are installed on the outer wall of the main body and are used for combined dust removal of dust-laden gas. The filter assembly is installed inside the main body and is used for secondary interception of the treated gas.

[0006] Furthermore, the restricted agencies also include: The central component is installed at the bottom of the fixed frame and is used to close after the pulse gas is ejected from the pulse gas canister to ensure the pulse intensity of the gas inside the filter assembly. Auxiliary components are installed on the outer surface of the central component.

[0007] Furthermore, the driving components also include: The active component is mounted on top of the conical ring and is used to expand outward under the impact of pulsed gas. A deformation component is installed on the side wall of the movable component and is used to slide upward as the movable component moves.

[0008] Furthermore, the dust removal assembly includes a cyclone separator bolted to the right side of the main body, and the main body and the interior of the cyclone separator are connected. The outer surface of the cyclone separator is bolted to a support frame, and a collection tank is fixedly connected to the bottom of the support frame; The outer surface of the main body is bolted to the top of the support frame.

[0009] Furthermore, the filter assembly includes a filter cylinder bolted to the inner wall of the top of the main body, and a return pipe is provided at the bottom of the filter cylinder; The return pipe is fixedly connected to the bottom outer wall of the main body, and the end of the return pipe away from the main body is fixedly connected to the side wall of the cyclone separator.

[0010] Furthermore, the mounting bracket is fixedly connected to the inside of the filter cartridge; The central component includes several conical arc plates rotatably connected to the bottom of the fixed frame, and the conical arc plates are arranged in a circular array around the fixed rod. Several conical arc plates can form a conical circular knot when they rotate close to each other.

[0011] Furthermore, the auxiliary component includes a cylinder fixedly connected to the outer surface of the fixed rod, and a piston plate is slidably connected inside the cylinder; A return spring is fixedly connected to the bottom of the piston plate, and the bottom of the return spring is fixedly connected to the inner wall of the bottom of the cylinder. The outer surface of the cylinder has several circular holes; In the initial state, the return spring is in a compressed state. When the piston plate slides upward and compresses the return spring to reset, the gas between the bottom of the piston plate and the inner wall of the bottom of the cylinder will be slowly discharged through the round hole during the piston plate reset process, thereby limiting the reset speed of the piston plate.

[0012] Furthermore, the movable component includes several connecting rods rotatably connected to the top of the conical ring, and the several connecting rods are arranged in a circular array around the fixed rod; A semi-circular plate is rotatably connected to the end of the connecting rod away from the conical ring; The outer surface of the semicircular plate is in contact with the inner wall of the filter cylinder. Multiple semicircular plates are combined to form an inclined ring, and the multiple semicircular plates can be separated from each other. A sliding frame is fixedly connected to the top of the connecting rod.

[0013] Furthermore, the deformation component includes a T-shaped rod slidably connected inside the sliding frame, and a cylindrical tube is fixedly connected between several T-shaped rods; The cylindrical tube is slidably connected to the outer surface of the fixed rod, and the bottom of the cylindrical tube is in contact with the top of the piston plate; Several T-shaped rods have folding elastic rings at their bottoms, and several connecting blocks are fixedly connected to the inner walls of the folding elastic rings. Several connecting blocks and a fixing rod are symmetrically distributed around the center, and the end of the connecting block away from the folding elastic ring is fixedly connected to the bottom of the connecting rod; A vertical plate is fixedly connected to the top of the T-shaped rod; The folded elastic ring is fitted into the folded troughs of the inner wall of the filter cartridge.

[0014] The present invention has the following beneficial effects: 1. This invention expands the pleated layer of the filter cartridge, forcibly stretching the pleated layer and increasing the gaps. At this time, the pulsed airflow inside the filter cartridge can more easily pass through and impact the impurities attached to the pleats, allowing the impurities inside the pleats to fall off without the support of the pleats. This avoids the situation where fine wood dust accumulates in the pleats on the outer surface of the filter cartridge, making it difficult for the pulsed airflow to remove dust deep in the pleats. This ensures the smooth flow of gas through the filter cartridge and improves the dust removal efficiency of the gas.

[0015] 2. This invention, by expanding the folded elastic ring within the pleats of the filter cartridge, avoids the problem of some pleated inner walls sticking together and causing the pleat layer to close due to pressure on the inner wall when the semi-circular plate pushes the inner wall of the filter cartridge outward, thus ensuring the effectiveness of pulse cleaning of impurities on the surface of the filter cartridge and improving the uniformity of pulse cleaning of impurities on the surface of the filter cartridge.

[0016] 3. This invention limits the reset speed of multiple semicircular plates and filter cylinder after expansion by using a cylindrical tube and a T-shaped rod. This prevents the folds on the filter cylinder from closing too quickly after the multiple semicircular plates expand the folds, which would cause the folds on the filter cylinder to close before the pulse gas dissipates. This improves the continuity and stability of the pulse gas dust removal process and ensures the permeability of subsequent gas passing through the filter cylinder.

[0017] 4. This invention enables the pulsed gas generated by the pulse gas tank to forcefully impact multiple semi-circular plates and generate an outward impact force within the filter cartridge. This reduces the occurrence of partial gas discharge and pressure relief from the top of the main body during the formation of the pulsed gas inside the filter cartridge, ensuring the impact strength of the pulsed gas on the multiple semi-circular plates inside the filter cartridge, improving the cleaning efficiency of impurities on the surface of the filter cartridge, and ensuring the continuity of the dust removal process of the filter cartridge.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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

[0023] Please see Figures 1-8 As shown, this invention is an environmentally friendly dust removal device for furniture processing, including a main body 1, with a pulse gas tank 101 fixedly connected to the top of the main body 1. The output end of the pulse gas tank 101 is located inside the main body 1. It also includes: The limiting mechanism 2 is installed inside the main body 1 to improve the removal rate of impurities when the pulse gas tank 101 is working. The limiting mechanism 2 includes a fixing frame 201 disposed inside the main body 1, and a fixing rod 211 is fixedly connected to the bottom of the fixing frame 201; Push component 3 is installed on the outer surface of fixed rod 211; The pushing component 3 includes three limiting plates 301 fixedly connected to the outer surface of the fixed rod 211, and a conical ring 311 is fixedly connected to one end of the three limiting plates 301 away from the fixed rod 211.

[0024] Entity 1 includes: Dust removal component 11 is installed on the outer wall of the main body 1 and is used for combined dust removal of dust-laden gas; The filter assembly 12 is installed inside the main body 1 and is used to perform secondary interception of the treated gas.

[0025] Restriction agency 2 also includes: The central component 21 is installed at the bottom of the mounting bracket 201 and is used to close after the pulse gas canister 101 sprays out pulse gas to ensure the pulse intensity of the gas inside the filter assembly 12. Auxiliary component 22 is mounted on the outer surface of central component 21.

[0026] Component 3 also includes: The active component 31 is mounted on top of the conical ring 311 and is used to expand outward under the impact of the pulsed gas. Deformation component 32 is installed on the side wall of movable component 31 and is used to slide upward as movable component 31 moves.

[0027] Dust removal assembly 11 includes a cyclone separator 111 bolted to the right side of the main body 1, and the main body 1 and the interior of the cyclone separator 111 are connected. A support frame 112 is bolted to the outer surface of the cyclone separator 111, and a collection tank 113 is fixedly connected to the bottom of the support frame 112; The outer surface of the main body 1 is bolted to the top of the support frame 112; Connect the external dust removal duct to the air inlet of the cyclone separator 111. The dust-laden gas generated during furniture processing enters the cyclone separator 111 for centrifugal classification, and large wood shavings fall into the collection tank 113 for storage.

[0028] The filter assembly 12 includes a filter cylinder 121 bolted to the inner wall of the top of the main body 1, and a return pipe 122 is provided at the bottom of the filter cylinder 121. The return pipe 122 is fixedly connected to the bottom outer wall of the main body 1, and the end of the return pipe 122 away from the main body 1 is fixedly connected to the side wall of the cyclone separator 111.

[0029] The mounting bracket 201 is fixedly connected to the inside of the filter cartridge 121; The central component 21 includes a plurality of conical arc plates 212 rotatably connected to the bottom of the fixed frame 201, and the plurality of conical arc plates 212 are arranged in a circular array around the fixed rod 211. When several conical arc plates 212 rotate close to each other, they can form a conical circular knot; When external gas passes through the filter cylinder 121 normally, some of the gas will form a vortex at the angle between the fixed rod 211 and the inclined ring composed of multiple semi-circular plates 313, forming a continuous backlash force from the inside of the filter cylinder 121 outward. This backlash force can continuously act on the filter media of the filter cylinder 121.

[0030] The auxiliary component 22 includes a cylinder 221 fixedly connected to the outer surface of the fixed rod 211, and a piston plate 222 is slidably connected inside the cylinder 221; A return spring is fixedly connected to the bottom of the piston plate 222, and the bottom of the return spring is fixedly connected to the bottom inner wall of the cylinder 221. The outer surface of the cylinder 221 has several circular holes; In the initial state, the return spring is in a compressed state. When the piston plate 222 slides upward and compresses the return spring to reset, the gas between the bottom of the piston plate 222 and the inner wall of the bottom of the cylinder 221 will be slowly discharged through the round hole during the reset process of the piston plate 222, thereby limiting the reset speed of the piston plate 222.

[0031] The movable component 31 includes a plurality of connecting rods 312 rotatably connected to the top of the conical ring 311, and the plurality of connecting rods 312 are arranged in a circular array around the fixed rod 211. A semi-circular plate 313 is rotatably connected to the end of the connecting rod 312 away from the conical ring 311; The outer surface of the semicircular plate 313 is in contact with the inner wall of the filter cylinder 121. Multiple semicircular plates 313 are combined to form an inclined ring, and multiple semicircular plates 313 can be separated from each other. A sliding frame is fixedly connected to the top of the connecting rod 312; By closing multiple conical arc plates 212 to block the gas discharge channel, the pulse gas generated by the pulse gas tank 101 can form a powerful impact on multiple semi-circular plates 313 and generate an outward impact force in the filter cylinder 121, thereby reducing the situation where some gas is discharged from the top of the main body 1 and depressurized during the formation of pulse gas inside the filter cylinder 121.

[0032] Deformation component 32 includes a T-shaped rod 322 slidably connected inside the sliding frame, and a cylindrical tube is fixedly connected between several T-shaped rods 322; The cylindrical tube is slidably connected to the outer surface of the fixed rod 211, and the bottom of the cylindrical tube is in contact with the top of the piston plate 222; Several T-shaped rods 322 are provided with folding elastic rings 321 at their bottoms, and several connecting blocks are fixedly connected to the inner wall of the folding elastic rings 321. Several connecting blocks are symmetrically distributed around the central fixing rod 211, and the end of the connecting block away from the folding elastic ring 321 is fixedly connected to the bottom of the connecting rod 312; A vertical plate is fixedly connected to the top of the T-shaped rod 322; The folded elastic ring 321 is fitted into the folded troughs of the inner wall of the filter cylinder 121.

[0033] Before use, connect the external dust removal duct to the air inlet of the cyclone separator 111. The dust-laden gas generated during furniture processing enters the cyclone separator 111 for centrifugal classification. Large particles of wood shavings fall into the collection tank 113 for storage, while the gas containing fine impurities enters the interior of the main body 1. As the gas continuously enters, the gas inside the main body 1 passes through the filter cartridge 121, where fine impurities are intercepted. The clean gas is then discharged outward through the top of the main body 1. At the same time, pulse gas is delivered into the filter cartridge 121 from the pulse gas tank 101 at intervals to remove impurities adhering to the surface of the filter cartridge 121. Meanwhile, the gas containing impurities inside the main body 1 also enters the cyclone separator 111 through the return pipe 122 for secondary filtration, achieving the purpose of environmental dust removal during furniture processing.

[0034] When external gas passes through the filter cartridge 121 normally, some of the gas forms a vortex at the angle between the fixed rod 211 and the inclined ring composed of multiple semicircular plates 313, creating a continuous backlash force from the inside of the filter cartridge 121 outwards. This backlash force continuously acts on the filter media of the filter cartridge 121, disturbing the deposited dust on the surface of the filter cartridge 121 when it is first deposited. Later, when the pulse gas canister 101 forms a pulse gas impact inside the filter cartridge 121, the pulse airflow jet impacts the surface of the multiple semicircular plates 313. At this time, the multiple semicircular plates 313 are impacted by the pulse airflow. As the multiple semicircular plates 313 expand outward, they adhere to the inner wall of the filter cylinder 121 and expand the pleated layer of the filter cylinder 121. This forces the pleated layer of the filter cylinder 121 to be stretched and the gaps to increase. At this time, the pulse airflow inside the filter cylinder 121 can more easily pass through and impact the impurities attached to the pleats. This allows the impurities inside the pleats of the filter cylinder 121 to lose the support of the pleats and fall off. This avoids the situation where fine wood dust accumulates in the pleats on the outer surface of the filter cylinder 121, making it difficult for the pulse airflow to remove dust deep in the pleats. This ensures the smooth flow of gas through the filter cylinder and improves the dust removal efficiency of the gas.

[0035] When the multiple semicircular plates 313 expand outward, they drive the folded elastic ring 321 through the connecting block, causing the folded elastic ring 321 to deform outward. Since the convex part of the folded elastic ring 321 is embedded in the recess of the inner wall of the filter cylinder 121 in the initial state, when the folded elastic ring 321 expands outward, it will push to both sides of the recess of the inner wall of the filter cylinder 121 and separate the filter media layers on both sides of the folds of the filter cylinder 121. Through the expansion of the folded elastic ring 321 in the folds of the filter cylinder 121, the problem of some folded inner walls sticking together and causing the folded layer to close due to the pressure on the inner wall when the semicircular plates 313 push the inner wall of the filter cylinder 121 outward can be avoided. This ensures the effectiveness of pulse cleaning of impurities on the surface of the filter cylinder 121 and improves the uniformity of pulse cleaning of impurities on the surface of the filter cylinder 121.

[0036] When the multiple semicircular plates 313 expand outward under the impact of the pulsed airflow, the expansion of the multiple semicircular plates 313 will drive the sliding frame to slide synchronously. At this time, the T-shaped rod 322 will slide upward inside the sliding frame under the guidance of its inclined surface. When the multiple T-shaped rods 322 slide upward, they will drive the cylindrical cylinder to slide synchronously. During the upward sliding of the cylindrical cylinder, it will no longer squeeze the piston plate 222. At this time, the piston plate 222 will slide upward inside the cylinder 221 under the push of the elastic potential energy of the return spring. Then, when the semicircular plates 313 are pushed back to their original position by the rebound of the inner wall of the filter cylinder 121, the cylindrical cylinder will slide downward and squeeze the piston plate 222. When the piston plate 222 slides downward... When in motion, the piston plate 222 will compress the gas between its bottom and the inner wall of the bottom of the cylinder 221. The compressed gas will be slowly discharged through the round hole on the cylinder 221, thereby slowing down the reset speed of the piston plate 222. At this time, the piston plate 222 can limit the reset speed of the multiple semicircular plates 313 and the filter cylinder 121 after expansion through the cylindrical tube and the T-shaped rod 322. This prevents the multiple semicircular plates 313 from closing too quickly after opening the pleats of the filter cylinder 121, which would result in the pleats on the filter cylinder 121 closing before the pulse gas dissipates. This improves the continuity and stability of the pulse gas dust removal process and ensures the permeability of subsequent gas passing through the filter cylinder 121.

[0037] When multiple semicircular plates 313 expand outward after being impacted by pulsed gas and slide upward through the sliding frame, the T-shaped rods 322 push against the sidewalls of the conical arc-shaped plates 212 via the vertical plate. At this time, the multiple conical arc-shaped plates 212 rotate closer to each other under the push of the vertical plate. When the multiple conical arc-shaped plates 212 rotate relative to each other, they form a conical cylindrical structure at the outlet of the top inner wall of the main body 1, blocking most of the exhaust channels on the top inner wall of the main body 1. After the plate 212 is closed, it blocks the gas discharge channel, which enables the pulse gas generated by the pulse gas tank 101 to form a powerful impact on the multiple semi-circular plates 313 and generate an outward impact force inside the filter cartridge 121. This reduces the situation where some gas is discharged from the top of the main body 1 and depressurized during the formation of the pulse gas inside the filter cartridge 121, ensuring the impact intensity of the pulse gas on the multiple semi-circular plates 313 inside the filter cartridge 121, improving the cleaning efficiency of impurities on the surface of the filter cartridge 121, and ensuring the continuity of the dust removal process of the filter cartridge 121.
