Abstract

This invention belongs to the field of vacuum equipment technology and discloses a high-efficiency dust treatment device that prevents clogging. The device includes a bag filter chamber. Through the structural cooperation of a linkage horizontal plate, a self-resetting rotating shaft, a vertical rod, and a rigid abutment ball, the invention utilizes a high-pressure pulsed airflow to blow the filter bag while simultaneously acting directionally on the linkage horizontal plate. This drives the horizontal plate to overcome its initial tilt angle limitation and rotate downwards. Then, the vertical rod drives the rigid abutment ball to move downwards synchronously, precisely squeezing and vibrating the thin steel sheet, causing it to tilt and store elastic potential energy. After the pulsed airflow stops, the self-resetting rotating shaft releases its return torque, driving the linkage horizontal plate to reverse and causing the rigid abutment ball to move upwards and disengage. This achieves periodic and precise tapping of the thin steel sheet, triggering an auxiliary dust removal mechanism without an additional power source. This effectively solves the problem that existing pulse dust removal systems rely solely on airflow scouring and lack the ability to remove caking or stubborn dust.

Description

Technical Field

[0001] This invention belongs to the field of dust collection equipment technology, specifically a high-efficiency dust treatment device that prevents clogging. Background Technology

[0002] In the fields of industrial dust removal and agricultural material processing, baghouse dust collectors are widely used for the purification of dust-laden gases due to their high filtration efficiency and stable operation. Existing baghouse dust collectors are usually equipped with a pulse jet cleaning system. Its basic working principle is as follows: during the intervals between filtration operations, high-pressure pulse airflow is injected into the interior of the dust-laden filter bags through reverse pulse nozzles, causing the filter bags to expand instantaneously and generate reverse wind speed, thereby blowing off the dust layer adhering to the outer surface of the filter bags and achieving filter bag regeneration.

[0003] For example, the dust collector bag disclosed in CN104971564A includes a fastening ring and a bag. The surface of the bag is provided with a pleated layer, and the total surface area of ​​the bag is larger than the total surface area of ​​a straight-tube bag with the same circumference as the bag opening and the fastening ring. Because the bag has a pleated layer, its total surface area available for dust removal is greater than that of the straight-tube bag in the prior art, allowing it to withstand a higher dust removal load and thus providing a dust collector bag with a greater dust removal load. This application also provides a baghouse dust collector including the above-mentioned dust collector bag.

[0004] While the above solutions enable the filter bags to withstand higher dust collection loads, in practical applications, existing pulse jet cleaning methods rely solely on the impact force of high-pressure airflow to sweep away the dust layer. The airflow blowing time is extremely short. Once the pulse stops, the dust that has not been completely removed is easily and quickly re-adhere to the filter bag surface under the action of gravity and airflow disturbance, reducing cleaning efficiency and even causing frequent equipment shutdowns for maintenance in severe cases. Although some existing technologies have attempted to assist cleaning with mechanical vibration, most of them require additional independent vibration motors or knocking devices, which not only increases equipment costs and energy consumption, but also makes it difficult to achieve effective vibration coverage of the entire filter bag area due to the limited installation position of the additional components. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a high-efficiency dust treatment device that prevents clogging.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency dust treatment device for preventing clogging, comprising a bag filter chamber, an air suction pipe fixedly connected to one side of the bag filter chamber, a conical dust collection chamber fixedly connected to the lower end of the bag filter chamber, a plurality of evenly distributed dust-collecting bags installed in the inner cavity of the bag filter chamber, a plurality of sets of transverse pipes fixedly connected above the inner cavity of the bag filter chamber, a plurality of reverse pulse ports fixedly connected to the lower end of the transverse pipes, the plurality of reverse pulse ports being located directly above the corresponding dust-collecting bags, and further comprising: a linkage vibration cleaning component for assisting in dust removal;

[0007] The linkage vibration dust removal assembly includes a U-shaped offset bracket fixedly connected to the lower end of the reverse pulse nozzle. A self-resetting rotating shaft is installed in the middle of the horizontal section of the U-shaped offset bracket. A linkage horizontal plate is fixedly connected to one side of the self-resetting rotating shaft. A bearing lug is fixedly connected to the lower end of the linkage horizontal plate. A vertical rod that always maintains a vertical state is rotatably connected to the lower end of the bearing lug. A ring-shaped fixing ring is fixedly connected to the top of the outer side of the bag filter dust collector chamber. An L-shaped side rod is fixedly connected to one side of the lower end of the ring-shaped fixing ring. A clamping block is fixedly connected to the horizontal section of the L-shaped side rod. A vibration rebound thin steel sheet is fixedly connected to one side of the clamping block.

[0008] Preferably, the upper end of the vibrating and rebounding thin steel sheet is fixedly connected with a number of protruding particle blocks that are evenly spaced, and the lower end of the vertical pole is fixedly connected with a hard abutment ball. The hard abutment ball and the protruding particle blocks are located on the same vertical axis, and the center of the hard abutment ball is aligned with the center of the protruding particle blocks.

[0009] Preferably, the rigid ball is fixedly connected to a side cleaning component, the side cleaning component including an elastic connecting vertical member fixedly connected in a ring shape to the lower end of the rigid ball, and a flexible ball is fixedly connected to the lower end of the elastic connecting vertical member.

[0010] Preferably, the plurality of elastic connecting vertical members are evenly distributed along the circumference of the rigid ball and are set at different heights, and the flexible ball is made of silicone material.

[0011] Preferably, the center of the U-shaped offset bracket is located at two-thirds of the inner diameter of the bag filter chamber, and the vertical section of the U-shaped offset bracket is arranged facing the inner wall of the bag filter chamber.

[0012] Preferably, the initial state of the linkage plate is tilted 30 degrees relative to the horizontal direction towards the side closer to the reverse pulse nozzle. After being blown by the high-pressure airflow ejected from the reverse pulse nozzle, it is pressed down to the horizontal state to release the tilt.

[0013] Preferably, the dust collection bag is made of waterproof polyester needle-punched felt, and its upper end is fixedly connected to the top of the inner cavity of the bag dust collector by a detachable clamp. The length of the dust collection bag is two-thirds of the height of the bag dust collector cavity, and the lower end does not contact the inner wall of the conical dust collection chamber.

[0014] Preferably, the multiple sets of transverse pipes are evenly distributed parallel to each other along the length of the bag filter chamber, and the spacing between adjacent sets of transverse pipes is consistent.

[0015] Preferably, the outlet end of the reverse pulse nozzle has a horn-shaped structure, with the horn facing downwards and corresponding to the upper opening of the corresponding dust bag.

[0016] Preferably, the self-resetting shaft includes a shaft body and a torsion spring sleeved on the outside of the shaft body. The torsion spring is in a pre-tightened state, with one end welded and fixed to the horizontal section of the U-shaped offset bracket, and the other end welded and fixed to the end of the linkage plate near the self-resetting shaft. The shaft body is installed in conjunction with the middle of the horizontal section of the U-shaped offset bracket through a deep groove ball bearing to ensure smooth rotation.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a structure consisting of a linkage horizontal plate, a self-resetting rotating shaft, a vertical pole, and a rigid abutment ball. High-pressure pulsed airflow acts directionally on the linkage horizontal plate while simultaneously blowing the filter bag, causing it to overcome its initial tilt angle and rotate downwards. The vertical pole then drives the rigid abutment ball downwards synchronously, precisely compressing and vibrating the thin steel sheet, causing it to tilt and store elastic potential energy. Once the pulsed airflow stops, the self-resetting rotating shaft releases its return torque, driving the linkage horizontal plate to reverse and causing the rigid abutment ball to move upwards and disengage. The kinetic energy of the pulsed airflow is converted into mechanical energy storage and release, achieving periodic and precise tapping of the thin steel sheet. This triggers the auxiliary dust removal mechanism without requiring an additional power source, effectively solving the problem that existing pulsed dust removal systems rely solely on airflow scouring and lack the ability to remove caking or stubborn dust.

[0018] This invention utilizes a structure consisting of a vibrating, rebounding thin steel sheet, protruding particle blocks, and elastic connecting vertical members. When the hard abutment ball disengages, the vibrating, rebounding thin steel sheet instantly releases the external pressure constraint and quickly rebounds to its original position due to the elastic properties of its metallic material. Simultaneously, under the influence of inertia, the thin steel sheet forms a continuous reciprocating elastic oscillation, driving the protruding particle blocks to vibrate at high frequency. This extends the single pulse jet blowing action into a long-term auxiliary dust removal action, significantly enhancing the loosening and removal of dust.

[0019] By setting up multiple sets of elastic connecting vertical members that are connected around the outside of the rigid ball, and each set of elastic connecting vertical members is arranged in a staggered manner with different heights, the elastic connecting vertical members of different lengths can cover different vertical height ranges. As the overall transmission structure generates swing vibration synchronously, these elastic connecting vertical members form a large-scale, multi-point flexible contact and tapping action, realizing the vibration and loosening of dust adhering to the side wall of the dust bag and the inner side wall of the equipment cavity at all heights, effectively avoiding the existence of blind spots in dust removal.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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] like Figures 1 to 6As shown, the present invention provides a high-efficiency dust treatment device with anti-clogging capability, including a bag filter chamber 1. An air suction pipe 2 is fixedly connected to one side of the bag filter chamber 1. A conical dust collection chamber 3 is fixedly connected to the lower end of the bag filter chamber 1. Multiple uniformly distributed dust collection bags 4 are installed in the inner cavity of the bag filter chamber 1. Multiple sets of transverse pipes 5 are fixedly connected to the upper part of the inner cavity of the bag filter chamber 1. Multiple reverse pulse ports 6 are fixedly connected to the lower end of the transverse pipes 5. The multiple reverse pulse ports 6 are respectively located directly above the corresponding dust collection bags 4.

[0024] The above scheme is adopted: the suction pipe 2 serves as the inlet for dusty gas, introducing the dusty air in the workshop into the chamber 1 of the bag filter. Multiple evenly distributed dust-collecting bags 4 serve as the core filter elements, providing sufficient filtration area to ensure that solid particles are efficiently intercepted on the outer surface of the bags when the dusty gas flows through, while clean air is discharged outward through the filter cloth. The conical dust collection chamber 3 is set at the bottom of the equipment. Its conical structure facilitates the automatic gathering of the removed dust towards the bottom center under gravity, making it easy to collect and discharge.

[0025] like Figures 2 to 6 As shown, the linkage vibration cleaning assembly 7 is used to assist in dust removal. The linkage vibration cleaning assembly 7 includes a U-shaped offset bracket 700 fixedly connected to the lower end of the reverse pulse pipe port 6. A self-resetting rotating shaft 701 is installed in the middle of the horizontal section of the U-shaped offset bracket 700. A linkage horizontal plate 702 is fixedly connected to one side of the self-resetting rotating shaft 701. A bearing lug 703 is fixedly connected to the lower end of the linkage horizontal plate 702. A vertical rod 704 that always maintains a vertical state is rotatably connected to the lower end of the bearing lug 703. A ring-shaped fixing ring is fixedly connected to the top of the outer side of the bag filter dust collector chamber 1. 710, an L-shaped side rod 705 is fixedly connected to one side of the lower end of the ring-shaped fixing ring 710. A clamping block 706 is fixedly connected to the horizontal section of the L-shaped side rod 705. A vibrating and rebounding thin steel sheet 708 is fixedly connected to one side of the clamping block 706. Several evenly spaced protruding particle blocks 709 are fixedly connected to the upper end of the vibrating and rebounding thin steel sheet 708. A hard abutment ball 707 is fixedly connected to the lower end of the vertical pole 704. The hard abutment ball 707 and the protruding particle blocks 709 are located on the same vertical axis, and the center of the hard abutment ball 707 is aligned with the center of the protruding particle blocks 709.

[0026] The above scheme is adopted: the bearing lug 703 and the vertical rod 704, which always maintains a vertical state, constitute a vertical motion conversion unit. Its function is that when the linkage horizontal plate 702 makes an arc-shaped downward pressing motion around the axis, the bearing lug 703 can adaptively adjust the connection angle, thereby driving the vertical rod 704 to move only vertically in a straight line downward, avoiding the generation of lateral swing components, and ensuring the motion accuracy of the end actuator, i.e., the hard ball.

[0027] like Figures 2 to 6 As shown, a side cleaning assembly 8 is fixedly connected to the rigid abutment ball 707. The side cleaning assembly 8 includes an elastic connecting vertical member 800 fixedly connected in a ring to the lower end of the rigid abutment ball 707. A flexible ball 801 is fixedly connected to the lower end of the elastic connecting vertical member 800. Multiple elastic connecting vertical members 800 are evenly distributed around the circumference of the rigid abutment ball 707 and are set at different heights. The flexible ball 801 is made of silicone. The center of the U-shaped offset bracket 700 is located at two-thirds of the inner diameter of the bag filter dust collector cavity 1. The vertical section of the U-shaped offset bracket 700 is set towards the inner wall of the bag filter dust collector cavity 1. The initial state of the linkage horizontal plate 702 is tilted 30 degrees relative to the horizontal direction towards the side close to the reverse pulse pipe 6. After being blown by the high-pressure airflow ejected from the reverse pulse pipe 6, it is pressed down to the horizontal state to release the tilt.

[0028] By adopting the above scheme, the heights of each elastic connecting vertical member 800 are set differently, so that the flexible ball 801 of different heights can correspond to different vertical areas of the side wall of the bag and the side wall of the inner cavity of the equipment, realizing full-height coverage of the patting from top to bottom. The design of the linkage horizontal plate 702 initially tilted at 30 degrees makes its plate surface form a non-perpendicular angle of attack with the direction of the high-pressure airflow ejected from the reverse pulse pipe 6. This angle can maximize the vertical component force on the plate surface and improve the energy conversion efficiency while ensuring that the airflow impact force is sufficient to drive the linkage horizontal plate 702 to rotate.

[0029] like Figures 1 to 6 As shown, the dust collection bag 4 is made of waterproof polyester needle-punched felt. Its upper end is fixedly connected to the top of the inner cavity of the bag dust collector chamber 1 by a detachable clamp. The length of the dust collection bag 4 is two-thirds of the height of the bag dust collector chamber 1. The lower end does not contact the inner wall of the conical dust collection chamber 3. Multiple sets of transverse pipes 5 are evenly distributed parallel to each other along the length of the bag dust collector chamber 1, and the spacing between adjacent sets of transverse pipes 5 is consistent. The outlet end of the reverse pulse pipe 6 is a horn-shaped structure, with the horn facing downward and corresponding to the upper opening of the corresponding dust collection bag 4. The self-resetting rotating shaft 701 includes a rotating shaft body and a torsion spring sleeved on the outside of the rotating shaft body. The torsion spring is in a pre-tightened state. One end of the spring is welded and fixed to the horizontal section of the U-shaped offset bracket 700, and the other end is welded and fixed to the end of the linkage horizontal plate 702 near the self-resetting rotating shaft 701. The rotating shaft body is installed in conjunction with the middle of the horizontal section of the U-shaped offset bracket 700 through a deep groove ball bearing to ensure smooth rotation.

[0030] The above solution is adopted: the dust bag 4 is made of waterproof polyester needle-punched felt. The surface of this material has hydrophobic properties, which can effectively prevent the filter cloth from absorbing moisture and caking due to humidity or oil in the cultivation material dust, maintain the air permeability of the filter cloth pores, and extend the dust cleaning cycle.

[0031] Working principle and usage process of this invention: First, the bag filter chamber 1 continuously adsorbs workshop gas containing dust impurities through the suction pipe 2. The airflow mixed with dust is smoothly introduced into the bag filter chamber 1. The solid dust particles in the gas are completely blocked on the outer surface by multiple evenly distributed dust-collecting bags 4 and gradually accumulate and adhere. The filtered clean air is smoothly discharged outward. During the intervals between normal dust collection operations, the entire pulse control program runs automatically, and the internal pulse cleaning operation is started simultaneously. Then, the reverse pulse nozzle 6 continuously sprays high-pressure pulse airflow downward in a directional manner. The high-pressure airflow directly washes the outer surface of the dust-collecting bags 4, realizing the basic air blowing cleaning of the dust accumulated on the surface of the dust-collecting bags 4. Simultaneously, the high-pressure airflow, while blowing the filter bag, acts directionally on the upper surface of the linkage horizontal plate 702, and the U-shaped offset bracket 700 is stably installed. The U-shaped offset bracket 700 stably supports the self-resetting rotating shaft 701 to complete the limiting and overall fixation of the rotation structure. Then, relying on the impact force of the airflow, the linkage horizontal plate 702 overcomes its initial tilt angle limitation and rotates downward with the cooperation of the rotation of the self-resetting rotating shaft 701. Then, during the angle adjustment process, the linkage horizontal plate 702 simultaneously drives the vertical pole 704 fixed at the lower end to maintain a uniform speed in the vertical direction. The vertical pole 704 moves downwards, pulling the rigid ball 707 mounted at the bottom downwards in sync. Simultaneously, the L-shaped side pole 705 remains fixed in its installed position. The L-shaped side pole 705 is locked in place by the clamping block 706 connected to its end, stabilizing and fixing the side position of the vibrating and rebounding thin steel sheet 708. The circular fixing ring 710 is securely installed on the top outer side of the bag filter chamber 1, locking and limiting the installation position of the L-shaped side pole 705, continuously maintaining the overall stability of the side support structure. The rigid ball 707 then continues to move downwards. 07. Gradually, the protruding particles 709 on the top of the contact contact oscillating and rebounding thin steel sheet 708 are squeezed, and the continuous pressure forces the oscillating and rebounding thin steel sheet 708 to tilt and store elastic potential energy. After the single pulse jet process ends, the reverse pulse nozzle 6 immediately stops the high-pressure airflow output, and then the self-resetting shaft 701 releases the internally stored return torque, synchronously driving the pressure-deflected linkage horizontal plate 702 to rotate in the opposite direction and return to the initial tilted state. Then, while the linkage horizontal plate 702 is resetting and rotating, it drives the vertical pole 704 to lift upwards synchronously. Rod 704 drives the hard ball 707 to move upward synchronously and completely detach from the squeezing contact position. Finally, the oscillating and rebounding thin steel sheet 708 instantly releases the external squeezing load constraint and quickly rebounds and resets itself due to the elastic properties of its own metal material. Under the action of inertia, it forms a continuous reciprocating elastic oscillation swing state. At the same time, the protruding particle block 709 follows the oscillating and rebounding thin steel sheet 708 to perform high-frequency reciprocating vibration. Relying on the transmission effect of mechanical vibration, it assists in the complete peeling and removal of the dust accumulated on the outer wall of the dust collection bag 4 and the bottom of the inner wall of the dust collection equipment cavity 1. Furthermore, the elastic connecting vertical members 800 connected to the outer side of the rigid ball 707 swing and vibrate synchronously with the overall transmission structure. Multiple sets of elastic connecting vertical members 800 are arranged in a staggered manner with different heights. The elastic connecting vertical members 800 of different lengths can cover different vertical height ranges, forming a large-scale multi-point flexible contact and patting action. Relying on the continuous reciprocating patting and vibration effect, it helps to complete the vibration, loosening and complete peeling and removal of dust attached to the side wall area of ​​the dust bag 4 and the inner side wall of the dust collector chamber 1.
