Description

Technical Field

[0001] The invention relates to the technical field of bag dust collectors, in particular to a high-efficiency pulse bag dust collector and a dust cleaning method thereof. Background Art

[0002] Bag dust collector is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of preventive filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle down due to gravity and fall into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] The existing bag filter first allows the dusty gas to enter the ash hopper from the air intake pipe and flow upward. Some large dust particles are separated and fall into the ash hopper due to the inertial force. The dusty gas enters the middle box and is filtered and purified by the filter bag. The dust is retained on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag port and is discharged from the air outlet. However, as the use time increases, the bag is gradually blocked by dust, resulting in a decrease in overall air permeability. To ensure the normal operation of the dust collector, the bag must be cleaned regularly.

[0004] However, traditional bag dust collectors have many disadvantages:

[0005] On the one hand, it requires regular manual inspection, which is cumbersome to operate. It not only consumes a lot of manpower and time, but also the accuracy and timeliness of manual inspection are difficult to guarantee. Problems may not be discovered in time, affecting the performance and service life of the dust collector.

[0006] On the other hand, in terms of cleaning methods, traditional bag dust collectors usually use a pulse method to clean the entire bag. This method cannot accurately clean bags that are severely clogged, which not only causes energy waste, but may also cause excessive cleaning of bags that are not severely clogged, shortening their service life. At the same time, the overall cleaning method may not be able to fully meet the actual cleaning needs of different bags, affecting the overall dust removal efficiency of the dust collector.

[0007] In view of this, this application is hereby filed. Summary of the invention

[0026] A dust cleaning method for a high-efficiency pulse bag dust collector comprises the following steps:

[0027] S1. Dust-laden gas enters: Dust-laden gas enters the dust removal chamber through the air inlet pipe and flows from bottom to top in the dust removal chamber. During the flow, the dust gradually adheres to the bag.

[0028] S2. Monitor the blockage situation: the pressure of each dust removal component that absorbs dust on the upper ring seat will be different, and each will move the dust removal skeleton up or down along its own axis; at this time, the upper ring seat is tilted, and the conductive ball rolls to the lowest point under the action of gravity. The conductive ball triggers and turns on the circuit, and the nozzles and opening and closing valves connected to the power strip start working, while the others do not start, and the bags with the most dust are cleaned.

[0029] S3. Pulse spraying: After the nozzle is turned on, the high-pressure pulse airflow generated by the pulser passes through the spray pipe and nozzle to carry out targeted cleaning of the seriously clogged cloth bags. The pulse airflow instantly impacts the cloth bags, causing them to expand instantly and shake off the dust attached to the outer surface of the cloth bags.

[0030] S4, balance seat reset: During the dust cleaning process, as the dust is shaken off, the weight of the dust removal part gradually decreases. The elastic force of the support spring causes the dust removal frame to slide upward, driving the balance seat to gradually restore the balance state. When the balance seat returns to the horizontal state, the conductive ball separates from the power supply sheet, the nozzle is closed, and the dust cleaning operation of the bag is stopped.

[0031] S5. Dust collection: The cleaned dust falls into the bottom funnel structure of the dust removal box under the action of gravity, and is discharged regularly through the ash discharge pipe and ash discharge valve.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In the present invention, the pressures of the dust removal parts for adsorbing dust on the upper ring seat are different, and each of them moves the dust removal frame up or down along its own axis. By utilizing the cooperation of the balance seat and the switch assembly, the blockage of the bag is automatically determined and the cleaning is triggered, thereby improving the intelligence level and cleaning efficiency of the dust collector, cleaning the bags with the most dust, and realizing targeted cleaning of the bags with more serious blockage, thus avoiding energy waste caused by overall cleaning.

[0034] 2. In the present invention, the slide groove inside the cartridge seat cooperates with the sliding sleeve, so that the outer filter cartridge can slide relative to the inner filter cartridge. The outer filter cartridge is sleeved on the outside of the inner filter cartridge, and the first filter hole on the outer filter cartridge corresponds to the second filter hole on the inner filter cartridge one by one. When the dust-laden gas passes through, it is double filtered, which improves the dust removal effect. The double filter cartridge structure enhances the filtering effect, can better block dust, and improves the dust removal efficiency of the dust collector. At the same time, when the dust removal part triggers the cleaning, the outer filter cartridge will slide relative to the inner filter cartridge, thereby reducing the size of the connecting part between the first filter hole and the second filter hole. When spraying and cleaning, the smaller filter hole can have a pressurizing effect, further improving the effect of spraying and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1 - Fig. 9 The present invention provides a technical solution: a high-efficiency pulse bag dust collector, comprising

[0047] A dust removal box 1 is formed with a dust removal chamber for dust-containing gas to flow from bottom to top, and a dust removal plate is arranged inside the dust removal chamber, and the dust removal chamber is divided into a dust removal chamber 3 and a purification chamber 4 by the dust removal plate;

[0048] The dust removal member 7 at least comprises a plurality of dust removal frames vertically mounted in the dust removal chamber 3 and a cloth bag 79 fixedly sleeved on the outside of the dust removal frame. The top of the dust removal frame extends through the dust removal flower plate to the inside of the purification chamber 4, and the dust removal frame can slide up and down along its own axis relative to the dust removal flower plate. A nozzle 13 is installed at a position inside the splicing plate 2 facing the dust removal member 7.

[0049] The balance seat includes a lower ring seat 22 arranged in parallel inside the dust removal chamber 3, a connecting frame 21 is installed inside the lower ring seat 22, a hinged rod 20 is rotatably connected to the center of the connecting frame 21, an inner support frame 19 is hinged on the top of the hinged rod 20, and an upper ring seat 18 is connected to the outside of the inner support frame 19. The upper ring seat 18 and the inner support frame 19 can swing freely with the hinged rod 20 as a fulcrum, and a support column 17 is hinged on the bottom surface of the dust removal frame, and the support column 17 is connected to the top surface of the inner support frame 19;

[0050] The switch assembly includes an annular groove 24 formed on the upper ring seat 18. An electrical connection plate for controlling the opening and closing of the nozzle 13 is provided on the inner side wall of the annular groove 24. A freely rolling conductive ball 25 is placed in the annular groove 24. When the conductive ball 25 contacts the electrical connection plate, the nozzle 13 is in an open state.

[0051] Specifically, the dust-laden gas flows from bottom to top in the dust removal chamber. During the flow, the dust gradually adheres to the cloth bag 79. The pressures of the dust removal components 7 that adsorb the dust on the upper ring seat 18 will be different, and each will move the dust removal frame up or down along its own axis; at this time, the upper ring seat 18 is tilted, and the conductive ball 25 rolls to the lowest point under the action of gravity. The conductive ball 25 is triggered and the circuit is turned on. The nozzle 13 and the opening and closing valve 14 connected to the power connection plate start working, and the rest are not started. The cloth bag 79 with the most dust attached is cleaned. During the cleaning process, as the dust is shaken off, the weight of the dust removal component 7 gradually decreases, and the elastic force of the support spring 73 causes the dust removal frame to slide upward, driving the balance seat to gradually restore the balance state. When the balance seat returns to a horizontal state, the conductive ball 25 separates from the power connection plate, the nozzle 13 is closed, and the cleaning operation of the cloth bag 79 is stopped.

[0052] See also Figure 4 The dust removal plate is composed of a plurality of independent splicing plates 2, and after the splicing is completed, the whole plate has a rectangular plate structure, on which at least three mounting holes are provided, and the three mounting holes are connected on the central axis of the same plane to form an isosceles triangle, and the dust removal frame can slide along the inner wall of the mounting hole in a sealed manner.

[0053] It should be noted that three dust removal components 7 are installed on a single splicing plate 2 to form a dust removal unit. Multiple dust removal units are arranged in the dust removal chamber 3, and the dust removal effect is achieved through the cooperation of the multiple dust removal units.

[0054] See also Fig. 9, dust removal skeleton includes

[0055] The cartridge seat 71 is slidably disposed inside the mounting hole, and its bottom end extends toward the lower part of the mounting hole and is connected to an inner filter cartridge 74, on which a second filter hole 78 is formed;

[0056] The support spring 73 is sleeved on the outside of the cylinder seat 71, with its top end connected to the outer wall of the cylinder seat 71 and its bottom end fixed to the top surface of the splicing plate 2;

[0057] See also Fig. 9 A slide groove 72 is formed inside the cartridge seat 71, and a sliding sleeve 75 is slidably installed inside the slide groove 72. The bottom of the sliding sleeve 75 is connected to an outer filter cartridge 76. The bottom end of the outer filter cartridge 76 is blocked and is sleeved on the outside of the inner filter cartridge 74. The outer filter cartridge 76 is also provided with a first filter hole 77 corresponding to the second filter hole 78. The support column 17 is connected to the bottom end of the outer filter cartridge 76, and the cloth bag 79 is fixedly sleeved on the outside of the outer filter cartridge 76.

[0058] Specifically, the slide groove 72 inside the cartridge seat 71 cooperates with the sliding sleeve 75 so that the outer filter cartridge 76 can slide relative to the inner filter cartridge 74. The outer filter cartridge 76 is sleeved on the outside of the inner filter cartridge 74, and the first filter hole 77 on the outer filter cartridge 76 corresponds one by one to the second filter hole 78 on the inner filter cartridge 74. When the dust-laden gas passes through, it is double filtered, which improves the dust removal effect. The double filter cartridge structure enhances the filtering effect, can better block dust, and improves the dust removal efficiency of the dust collector. At the same time, when the dust removal component 7 triggers cleaning, the outer filter cartridge 76 will slide relative to the inner filter cartridge 74, thereby reducing the size of the connecting portion between the first filter hole 77 and the second filter hole 78. During spray cleaning, the smaller filter holes can have a pressurizing effect, further improving the spray cleaning effect.

[0059] See also Figure 6 - Figure 8 , the terminal block includes

[0060] A first conductive sheet 26 is mounted on the side wall of the inner circle of the annular groove 24;

[0061] The second conductive sheet 27 is slidably mounted on the side wall of the inner ring of the annular groove 24 and is opposite to the first conductive sheet 26. An electrical connection channel for the conductive ball 25 to conduct is formed between the first conductive sheet 26 and the second conductive sheet 27.

[0062] A telescopic hose 23 corresponding to the position of the power connection channel is installed on the top surface of the lower ring seat 22. Fluid is arranged inside the telescopic hose 23. An expansion airbag 29 is installed on the side of the second conductive sheet 27 facing away from the first conductive sheet 26. The second conductive sheet 27 is fixed to the inner wall of the annular groove 24 through the expansion airbag 29. A flow channel 28 connected to the expansion airbag 29 is also opened on the upper ring seat 18. When the upper ring seat 18 is not parallel, the fluid in the telescopic hose 23 is injected into the expansion airbag 29 through the flow channel 28.

[0063] The first conductive sheet 26 is mounted on the inner side wall of the annular groove 24, and the second conductive sheet 27 is slidably mounted and opposite to the first conductive sheet 26. When the conductive ball 25 rolls to the power connection channel between the two, the circuit is turned on, and the nozzle 13 is controlled to open. The simple and reliable power connection sheet structure can accurately control the opening and closing of the nozzle 13, realize accurate dust cleaning of the bag 79, facilitate maintenance and replacement, and improve the reliability of the equipment;

[0064] The telescopic hose 23 on the top surface of the lower ring seat 22 is filled with fluid. When the upper ring seat 18 is not parallel, the fluid in the telescopic hose 23 is injected into the expansion airbag 29 through the flow channel 28, pushing the second conductive sheet 27 to move, adjusting the size of the power connection channel, and ensuring that the conductive ball 25 can smoothly conduct the circuit. On the one hand, it can automatically adapt to the shaking of the balance seat to ensure good contact between the conductive ball 25 and the power connection sheet, thereby improving the stability of the cleaning system and effectively preventing poor circuit contact caused by the shaking of the balance seat. On the other hand, the backflow of the fluid requires a certain amount of time. During this period of time, the nozzle 13 can continue to spray cleaning on the cloth bag 79 to ensure the cleaning effect.

[0065] See also Figure 3 A mesh plate 8 parallel to the splicing plate 2 is also installed inside the dust removal chamber 3, the dust removal member 7 is arranged between the splicing plate 2 and the mesh plate 8, and the balance seat is installed on the top surface of the mesh plate 8.

[0066] Specifically, the mesh plate 8 is provided to support the balance seat.

[0068] Specifically, after the nozzle 13 is turned on, the high-pressure pulse airflow generated by the pulser 10 passes through the blowing pipe 11 and the nozzle 13 to perform targeted cleaning on the cloth bag 79 that is severely clogged. The pulse airflow instantly impacts the cloth bag 79, causing the cloth bag 79 to expand instantly, thereby shaking off the dust attached to the outer surface of the cloth bag 79.

[0069] Reference Figure 1 - Figure 3 The dust removal box 1 has a rectangular box body on the upper part and a funnel structure on the lower part. An exhaust pipe 6 is opened on the side wall of the upper part of the rectangular box body. The exhaust pipe 6 is connected to the purification chamber 4. An air intake pipe 5 is arranged on the side wall of the funnel structure. The air intake pipe 5 is connected to the dust removal chamber 3. An ash discharge pipe 15 is also connected to the bottom end of the funnel structure, and an ash discharge valve 16 is arranged on the ash discharge pipe 15.

[0070] A dust cleaning method for a high-efficiency pulse bag dust collector comprises the following steps:

[0071] S1. Dust-containing gas enters: Dust-containing gas enters the dust removal chamber 3 through the air inlet pipe 5 and flows from bottom to top in the dust removal chamber 3. During the flow, dust gradually adheres to the bag 79.

[0072] S2. Monitor the blockage situation: the pressures of the dust removal components 7 for adsorbing dust on the upper ring seat 18 will be different, and each will move the dust removal frame up or down along its own axis; at this time, the upper ring seat 18 is tilted, and the conductive ball 25 rolls to the lowest point under the action of gravity. The conductive ball 25 is triggered and the circuit is turned on.

[0073] S3. Pulse spraying: After the nozzle 13 is turned on, the high-pressure pulse airflow generated by the pulser 10 passes through the spray pipe 11 and the nozzle 13 to perform targeted cleaning on the cloth bag 79 that is seriously clogged. The pulse airflow instantly impacts the cloth bag 79, causing the cloth bag 79 to expand instantly, and the dust attached to the outer surface of the cloth bag 79 is shaken off.

[0074] S4. Reset the balance seat: During the cleaning process, as the dust is shaken off, the weight of the dust removal component 7 gradually decreases, and the elastic force of the support spring 73 causes the dust removal frame to slide upward, driving the balance seat to gradually restore the balance state. When the balance seat returns to a horizontal state, the conductive ball 25 separates from the power supply sheet, the nozzle 13 is closed, and the cleaning operation on the bag 79 is stopped.

[0075] S5. Dust collection: The cleaned dust falls into the bottom funnel structure of the dust removal box 1 under the action of gravity, and is discharged regularly through the dust discharge pipe 15 and the dust discharge valve 16.

8. A high-efficiency pulse bag dust collector according to claim 1, characterized in that: The dust removal box (1) is provided with a bracket (9) on the outside for supporting it, a pulser (10) is installed on the top surface of the bracket (9), a plurality of blowing pipes (11) are connected to the pulser (10), a main blowing valve (12) is connected to the blowing pipe (11), the nozzle (13) is connected to the blowing pipe (11), and an on-off valve (14) for controlling the opening and closing of the nozzle (13) is also provided on the blowing pipe (11).

9. A high-efficiency pulse bag dust collector according to claim 1, characterized in that: The dust removal box (1) has a rectangular box body at the top and a funnel structure at the bottom. An exhaust pipe (6) is provided on the side wall of the upper part of the rectangular box body. The exhaust pipe (6) is connected to the purification chamber (4). An air intake pipe (5) is provided on the side wall of the funnel structure. The air intake pipe (5) is connected to the dust removal chamber (3).

10. A dust cleaning method for a high-efficiency pulse bag dust collector according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Dust-containing gas enters: The dust-containing gas enters the dust removal chamber (3) through the air inlet pipe (5), and flows from bottom to top in the dust removal chamber (3). During the flow, dust gradually adheres to the bag (79). S2. Monitoring the blockage situation: the pressures exerted by the dust collecting components (7) for adsorbing dust on the upper ring seat (18) are different, and each of them moves the dust collecting frame upward or downward along its own axis. At this time, the upper ring seat (18) tilts, and the conductive ball (25) rolls to the lowest point under the action of gravity. The conductive ball (25) triggers and conducts the circuit, and the nozzle (13) and the opening and closing valve (14) connected to the power strip start to work, while the others do not start, and the bag (79) with the most dust is cleaned. S3, pulse spraying: after the nozzle (13) is turned on, the high-pressure pulse airflow generated by the pulser (10) passes through the spray pipe (11) and the nozzle (13) to carry out targeted cleaning of the cloth bag (79) that is seriously clogged. The pulse airflow instantly impacts the cloth bag (79), causing the cloth bag to expand instantly, and the dust attached to the outer surface of the cloth bag (79) is shaken off. S4, balance seat reset: During the dust cleaning process, as the dust is shaken off, the weight of the dust removal component (7) gradually decreases, and the elastic force of the support spring (73) causes the dust removal frame to slide upward, driving the balance seat to gradually restore the balance state. When the balance seat returns to a horizontal state, the conductive ball (25) separates from the power connection plate, the nozzle (13) is closed, and the dust cleaning operation on the bag (79) is stopped. S5. Dust collection: The cleaned dust falls into the bottom funnel structure of the dust removal box (1) under the action of gravity, and is discharged regularly through the dust discharge pipe (15) and the dust discharge valve (16).
