Description

Technical Field

[0001] This invention relates to the field of environmentally friendly dust removal equipment for putty powder production, and in particular to a high-efficiency dust removal device for putty powder production. Background Technology

[0002] During the production of putty powder, key processes such as mixing, grinding, conveying, and packaging continuously generate a large amount of mixed coarse and fine dust. This dust not only causes raw material loss due to dispersion but also pollutes the production workshop environment, threatening the health of operators. Furthermore, the suspended combustible dust poses a hidden safety hazard. Currently available conventional dust removal equipment for putty powder suffers from three major problems: First, the dust removal structure is simplistic, relying solely on single-stage filtration or basic electrostatic precipitators, resulting in poor removal of ultrafine powder particles and severe dust escape. Second, core components such as filter cartridges and electrodes are prone to dust accumulation and clogging, with rudimentary cleaning methods leading to a sharp decline in dust removal efficiency over long-term operation, and cumbersome and inconvenient disassembly and maintenance. Third, there is a lack of targeted explosion-proof protection and operational status monitoring mechanisms, resulting in insufficient equipment stability and an inability to effectively control the risk of dust explosions. Therefore, providing a high-efficiency dust removal device for putty powder production is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0013] As a preferred embodiment of the present invention, the backflush cleaning assembly includes a plurality of backflush air pipes.

[0014] The beneficial effects of this invention are: 1. This high-efficiency dust removal device for putty powder production utilizes electrostatic condensation and enhanced efficiency, significantly reducing the difficulty of filtering ultrafine dust: This device generates a high-voltage electrostatic field through the barbed discharge electrodes of the air intake pretreatment component. It first charges the ultrafine dust particles dispersed in the putty powder, and then uses electrostatic adsorption to cause the fine dust particles to collide and agglomerate into larger dust particles. This fundamentally solves the industry pain point that ultrafine dust particles are too small, easily penetrate the filter cartridge, and are difficult to filter. It significantly reduces the difficulty of subsequent filtration, allowing filter cartridge one and filter cartridge two to easily intercept dust, completely eliminating the problem of ultrafine dust escape, and significantly improving the accuracy and effectiveness of dust removal.

[0015] 2. This putty powder production uses a high-efficiency dust removal device with intelligent linkage dust removal, ensuring long-term, clog-free operation of the equipment. The device is equipped with a pressure sensor that can monitor pressure changes within the main body of the device in real time and accurately, automatically determining the dust accumulation and clogging status of filter cartridges one and two. This enables fully automated monitoring of the equipment's operating status, eliminating the need for frequent manual inspections. Combined with the pulse high-pressure backflushing of the backflushing cleaning component and the synchronous vibration cleaning of the vibrating motor, this dual cleaning method ensures thorough cleaning without blind spots, completely solving the problems of easy filter cartridge clogging, incomplete cleaning, and frequent manual cleaning required by traditional dust removal equipment. This significantly extends the continuous operating time of the equipment, reduces the frequency of downtime maintenance, ensures the continuity of putty powder production, and improves overall production efficiency.

[0016] 3. This high-efficiency dust removal device for putty powder production features easy-to-disassemble and assemble components, reducing both maintenance costs and operational difficulty. The main body of the device has a dedicated loading and unloading port on the front. With the help of the track sealing groove, sealing arc plate, drive handle, locking groove and locking rod, the inspection port can be quickly opened and closed and sealed and locked. The electrode mounting frame and grounding dust collection net in the air intake pretreatment component adopt a snap-fit ​​design, which can be quickly fixed with positioning plate and auxiliary bolts. Filter cartridge one and filter cartridge two can be quickly loaded and unloaded by lifting cylinder. The core components are simple and convenient to inspect, replace and clean, without professional tools and complicated operations, which greatly reduces the difficulty of equipment maintenance and labor costs. It is suitable for use by putty powder production enterprises of different sizes.

[0017] 4. The putty powder production process utilizes a high-efficiency dust removal device with comprehensive safety protection, balancing environmental protection and raw material recycling benefits. The protective components can uniformly fill the device with nitrogen through nitrogen delivery pipes and annular inner delivery pipes, reducing the oxygen concentration inside the cavity and disrupting the conditions for dust explosion. This suppresses the risk of putty powder dust explosion at the source. Combined with real-time pressure monitoring and early warning from pressure sensors, this dual safety protection comprehensively eliminates potential production safety hazards. At the same time, the dust is collected and recycled in a fully enclosed manner, with no secondary leakage or pollution. The separated dust can also be returned to the production section for reuse, further reducing raw material loss and achieving the dual benefits of environmentally friendly dust removal and raw material conservation.

[0031] 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 invention, and therefore only show the components relevant to the invention.

[0032] refer to Figures 1-13 A high-efficiency dust removal device for putty powder production.

[0033] This embodiment includes: a device body 1; an air intake pretreatment component 2 for pre-treating dust is provided on the left side surface of the upper end of the device body 1; a self-detection filter component 3 for secondary filtration and purification of dust is connected to the bottom of the device body 1; a protective component 4 for explosion prevention is provided in the middle of the top surface of the inner cavity of the device body 1; an air outlet pipe 5 for conveying purified gas is connected to the right side surface of the lower end of the device body 1; a backflushing cleaning component 6 for backflushing the self-detection filter component 3 is installed on the left side surface of the lower end of the device body 1; a loading and unloading port 7 for maintaining the self-detection filter component 3 is provided on the front of the lower end of the device body 1; track sealing grooves 8 are provided on the inner walls of both sides of the loading and unloading port 7; a sealing arc plate 9 that slides with the inner wall of the track sealing groove 8 is engaged in the inner cavity of the track sealing groove 8; a drive handle 10 is fixedly connected to the front of the right end of the sealing arc plate 9; a locking groove 11 is provided on the right side of the loading and unloading port 7 and on the outer surface of the device body 1; a locking rod 12 corresponding to the position of the locking groove 11 is threadedly connected to the inner wall of the right end of the drive handle 10.

[0034] The air intake pretreatment component 2 includes an air intake pipe 201. The right end of the air intake pipe 201 is connected to the left side surface of the upper end of the main body 1. Three limiting grooves 202 are provided on the upper surface of the left end of the air intake pipe 201. An electrode mounting frame 203 is snapped into the inner cavity of each limiting groove 202. Several barbed rod-type discharge electrodes 204 are threadedly connected to the inner wall of the upper end of the electrode mounting frame 203. A second limiting groove 205 is provided on the upper surface of the right end of the air intake pipe 201. A metal grounding dust collection net 206 is inserted into the inner cavity of the second limiting groove 205. The top of the electrode mounting frame 203 is connected to... It has a handle with a built-in unloading hole, and the top of the grounding dust collection net 206 is connected to a handle; two guide slots 207 are opened on the upper surface of both ends of the air intake pipe 201, and a damping spring 208 is fixedly connected to the rear surface of the inner cavity of each guide slot 207. A slider 209 that slides against the inner wall of the guide slot 207 is fixedly connected to the front end of each damping spring 208. A positioning plate 210 is fixedly connected to the upper surface of the front end of each slider 209; the upper surfaces of both ends of the positioning plate 210 are threaded with auxiliary bolts 211 in the same number as the electrode mounting frame 203 and the grounding dust collection net 206.

[0035] Among them, by setting the barbed rod-type discharge electrode 204 and the grounded dust collection net 206, the shortcomings of ordinary air intake that only guides flow without modifying the properties are first overcome; at this time, the ultrafine dust of putty powder is electrostatically agglomerated into large particles, and then the static electricity of the dust is quickly eliminated. This will not stick to the dust collection net and clog the net, but will also allow the agglomerated large particles to flow smoothly downwards, which will greatly reduce the filtration load of the subsequent filter cartridge 1 310 and filter cartridge 2 311, and solve the problem of ultrafine powder permeation and incomplete dust removal from the root.

[0036] The self-testing filter assembly 3 includes a dust guide plate 301. The outer surface of the dust guide plate 301 is fixedly connected to the inner wall of the upper end of the device body 1. Four external mounting holes 302 are opened on the outer surface of the upper end of the device body 1. A vibration motor 303 corresponding to the position of each external mounting hole 302 is fixedly installed on the bottom surface of the inner cavity of the dust guide plate 301. An upper retaining ring 304 with a self-sealing gasket is fixedly connected to the lower surface of the dust guide plate 301. An upper retaining ring 305 connected to the bottom surface of the dust guide plate 301 is provided on the inner wall of the upper retaining ring 304. A sealing gasket is adhered to the inner cavity of the upper end of the upper retaining ring 305. A support plate 306 is fixedly installed at the bottom of the device body 1 by multiple bolts. Two lifting cylinders 307 are fixedly installed on the upper surfaces of both ends of the support plate 306. The upper end of 07 is fixedly installed with a lower retaining ring 308. The inner wall of the lower retaining ring 308 is fixedly connected with a lower retaining ring 309 through a sealing ring plate. The inner cavities of the lower retaining ring 308 and the upper retaining ring 304 are both fitted with filter cartridges 310. The inner cavities of the lower retaining ring 309 and the upper retaining ring 305 are both fitted with filter cartridges 311. The bottom surface of the lower retaining ring 308 is fixedly connected with a conical dust guide hopper 312. The middle position of the bottom surface of the support plate 306 is embedded with an elastic dust collection tube 313, and the upper end of the elastic dust collection tube 313 is fixedly connected to the lower end of the dust guide hopper 312. The outer surface of the lower end of the elastic dust collection tube 313 is threaded with a sealing cap 314. A pressure sensor 315 for detecting the pressure of the chamber of the device body 1 is fixedly installed on the left side of the upper surface of the device body 1.

[0037] Among them, the filter cartridge 310 and filter cartridge 311, compared with single-layer filter cartridges, provide graded interception without dead angles, and completely intercept all fine residual dust; the lifting retaining ring does not require disassembly and prying, and filter replacement and cleaning can be done with one-click alignment and sealing, doubling maintenance efficiency and preventing air leakage and dust loss due to misalignment of filter cartridges.

[0038] The system features a pressure sensor 315 and a vibration motor 303. The pressure sensor 315 monitors the resistance inside the chamber in real time, triggering a pulse jet from the backflushing cleaning component 6. The vibration motor 303 then simultaneously shakes off the accumulated dust. This eliminates the need for manual inspection for blockages and for stopping the machine to disassemble and clean the dust. If the pressure exceeds the limit, the system automatically triggers pulse backflushing and vibration to shake off the dust. The filter cartridges do not clump or become blocked over a long period of time, allowing the equipment to run continuously for extended periods, reducing downtime for maintenance, and maintaining a stable high dust removal efficiency.

[0039] The protective component 4 includes a nitrogen delivery pipe 401. The lower end of the nitrogen delivery pipe 401 is embedded in the right side of the upper surface of the device body 1. A solenoid valve 402 is fixedly installed on the left side surface of the middle section of the nitrogen delivery pipe 401. An annular inner delivery pipe 403 communicating with the lowermost end of the nitrogen delivery pipe 401 is fixedly connected to the top surface of the inner cavity of the device body 1. The bottom surface of the inner delivery pipe 403 is provided with evenly distributed air outlet holes.

[0040] Among them, the protective component 4 continuously reduces the oxygen content in the cavity and suppresses the conditions for dust suspension and explosion by taking into account the characteristics of combustible dust of putty powder; the solenoid valve 402 can be started and stopped in a controllable manner, and the annular gas distribution has no dead angle, which is safer and more uniform than single-point tube nitrogen filling, and completely avoids the hidden danger of dust explosion.

[0041] The backflush cleaning assembly 6 includes several backflush air pipes 601. The ends of each backflush air pipe 601 that are far apart from each other are embedded in the inner wall of the upper part of the device body 1. Several conical backflush air holes are opened on the side of each backflush air pipe 601 near the filter cartridge 310. A pulse valve 602 is fixedly installed at the end of each backflush air pipe 601 that extends to the outside of the device body 1. A pressure stabilizing air pipe 603 is fixedly installed at the air inlet at the lower end of each pulse valve 602. A high-pressure air tank 604 is fixedly installed on the left side surface of the lower end of the device body 1 by two clamps. The air outlet at the upper end of the high-pressure air tank 604 and the air inlet at the lower end of the pressure stabilizing air pipe 603 are fixedly connected by flange and bolts.

[0042] Working principle: First, dust-laden gas flows into the device through the inlet pipe 201 of the pretreatment component 2. The airflow passes sequentially through three sets of limiting slots 202 and is fixed to the electrode mounting frame 203. The three rows of electrodes adopt an alternating polarity layout with negative on both sides and positive in the middle. The barbed discharge electrodes 204 on the two side electrode mounting frames 203 are connected to high voltage negative electricity, and the barbed discharge electrodes 204 on the middle electrode mounting frame 203 are connected to high voltage positive electricity. The three rows of electrodes form a bipolar interactive high voltage corona field, which greatly extends the dust charging path and allows putty powder dust of different positions and particle sizes in the airflow to be uniformly charged. Some dust carries a positive charge and some carries a negative charge. The dust carrying opposite charges collides rapidly under the action of electric field force and airflow turbulence. Relying on the attraction of opposite charges, efficient electrostatic coagulation is achieved, and the dust quickly gathers into larger and heavier dust particles, which completely solves the problems of insufficient charging, insufficient coagulation, and easy leakage of ultrafine dust. Subsequently, the airflow carrying large dust particles continues forward, contacting the grounded dust collection net 206 fixed in place by the limiting slot 205. The grounded dust collection net 206 does not completely neutralize the dust electrostatically; it only weakens the residual strong electrostatic effect on the dust surface, eliminating excessive electrostatic adsorption and adhesion, and preventing large dust particles from sticking to the surface of the dust collection net or the pipe wall due to strong electrostatic adsorption, thus avoiding blockage. Simultaneously, relying on the continuous positive thrust of the airflow introduced through the intake pipe 201, the weakened large dust particles are directly and rapidly pushed to the right, leveling the surface. The dust is steadily guided to the self-detection filter component 3 area at the rear, ensuring that the dust flows smoothly without accumulation or retention, allowing the dust to enter the subsequent filtration station smoothly. At the same time, the vibration damping spring 208 inside the guide slot 207 continuously pushes the slider 209 forward, causing the positioning plate 210 to tightly press the electrode mounting frame 203 and the grounded dust collection net 206. Then, the auxiliary bolts 211 are used for secondary reinforcement and locking, effectively offsetting the vibration generated by the equipment operation, preventing the electrodes and dust collection net from loosening or shifting, and ensuring the stability and reliability of the bipolar electrostatic coagulation and electrostatic weakening guide process throughout the entire process. The dust-laden airflow, after electrostatic condensation and weakening treatment, enters the main body 1 of the device downwards under the push of the inlet airflow. First, it is evenly guided by the dust guide plate 301 to prevent airflow deviation and localized dust accumulation. Then, it enters the dual-layer filtration area of ​​the self-detecting filter assembly 3. Filter cartridge 1 310 is located on the outer side, and filter cartridge 2 311 is located on the inner side. The bottoms of both are completely sealed to prevent short-circuit flow. The airflow can only flow along a predetermined path, first undergoing primary coarse filtration through the outer filter cartridge 1 310, which primarily traps dust. The filter cartridge 310 intercepts most of the large particles of putty powder dust and undertakes the main dust collection and removal work. The intercepted dust settles downwards due to gravity. The gas that has been initially purified by the first filter cartridge 310 then enters the inner filter cartridge 311 for deep filtration. The second filter cartridge 311 focuses on isolating trace amounts of harmful substances, ultrafine impurities and incompletely condensed fine dust in the airflow, achieving secondary deep purification and thoroughly improving the cleanliness of the gas. The clean gas after the double-layer graded filtration is finally discharged smoothly from the outlet pipe 5 on the lower right side of the main body of the device. The external mounting hole 302 is used to securely install the vibration motor 303. The high-frequency vibration force generated by the vibration motor 303 is transmitted to the filter cartridge 310 and the filter cartridge 311 through the dust guide plate 301, which helps to shake off the dust adhering to the surface of the filter cartridge in real time and prevents dust from caking and clogging. The upper retaining ring 304 and the upper retaining ring 305 respectively fix the upper ends of the filter cartridge 310 and the filter cartridge 311. The support plate 306 bears the weight of the entire filter structure. The lifting cylinder 307 can drive the lower retaining ring 308 and the lower retaining ring 309 to move up and down, which facilitates the quick disassembly and replacement of the filter cartridge 310 and the filter cartridge 311 in the later stage. All dust intercepted and pre-treated by filter cartridge 310 settles downwards under the action of gravity and vibration, and is collected and guided by the conical dust guide hopper 312, falling steadily into the interior of the elastic dust collection tube 313. The sealing cap 314 is tightened to seal the lower end of the elastic dust collection tube 313, ensuring that the dust collection process is completely sealed and there is no dust leakage. After the dust accumulates to a certain amount, the sealing cap 314 can be unscrewed to remove the dust and return it to the putty powder production section for raw material reuse. The pressure sensor 315 monitors the pressure value inside the main body 1 of the device in real time. When the filter cartridge 310 and the filter cartridge... When excessive dust accumulation causes blockage in filter cartridge 311 and the internal pressure rises abnormally, the back-flushing cleaning component 6 is immediately triggered. The high-pressure air tank 604 stores high-pressure clean gas. After the gas is stabilized by the pressure-stabilizing air pipe 603, it is delivered to each pulse valve 602. The pulse valve 602 precisely controls the pulse ventilation rhythm. After the high-pressure gas enters the back-flushing air pipe 601, it is sprayed in reverse through the conical back-flushing air holes in the pipe wall into the interior of filter cartridge 310 and filter cartridge 311. In conjunction with the vibration motor 303, the dust accumulation on the surface of the filter cartridge is thoroughly removed, realizing fully automatic dust removal without stopping the machine. Throughout the entire operation of the machine, the explosion-proof protection component 4 is activated simultaneously. The nitrogen delivery pipe 401 is connected to an external nitrogen source, and the solenoid valve 402 precisely controls the on / off state and delivery flow of nitrogen. Nitrogen is introduced into the annular inner delivery pipe 403 through the nitrogen delivery pipe 401, and then diffused throughout the inner cavity of the main body 1 through the evenly distributed air outlet holes on the bottom surface of the annular inner delivery pipe 403, continuously reducing the internal oxygen concentration and completely destroying the explosion conditions of the combustible dust of the putty powder, thus eliminating the risk of explosion from the source. When it is necessary to inspect internal electrodes, filter cartridges, and other components, rotate the locking rod 12 to disengage it from the locking groove 11, hold the drive handle 10 to push the sealing arc plate 9 to slide smoothly along the track sealing groove 8, and quickly open the loading and unloading port 7 to carry out the inspection work. After the inspection is completed, reset the sealing arc plate 9, lock the locking rod 12 to restore the airtightness of the device, and ensure the normal and stable operation of subsequent dust removal operations.
