Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and in particular to a bag filter dust removal device for textile workshops. Background Technology

[0002] Textile workshops mainly generate dust such as cotton lint, short fibers, cotton dust, and chemical fiber lint, which need to be collected and cleaned using dust removal devices. The most common type is the baghouse dust collector. Baghouse dust collectors typically employ a bottom-inlet layout, allowing coarse dust and large lint to settle due to gravity, reducing the burden on the filter bags. During operation, dust-laden gas passes through the filter bags, and dust and lint are trapped on the outer surface of the bags, gradually accumulating to form a dust layer. This layer needs to be cleaned using pulse-jet cleaning to ensure continuous operation. However, pulse-jet cleaning disturbs the rising airflow, making it easy for the dust to be re-adsorbed by the rising airflow, leading to difficulties in online cleaning. This is the biggest challenge of bottom-inlet online cleaning.

Detailed Implementation

[0017] 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.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 11 As shown, this embodiment provides a baghouse dust collector for textile workshops, including a housing 1. A dust hopper 2 is connected to the bottom of the housing 1. A support 3 is fixedly connected to the outside of the dust hopper 2. Several bag cages 13 are arranged in an array inside the housing 1. A cloth bag is placed outside the bag cage 13. Adjacent rows of bag cages 13 are separated by a partition 14. A moving mechanism is fixedly installed on the inner wall of the housing 1. The moving mechanism is located below the bag cage 13 and is adapted to the bottom of the partition 14. A blowing mechanism is installed on the top of the housing 1. The blowing mechanism is located above the bag cage 13. An air outlet is provided on one side of the top of the housing 1. A connecting pipe 6 is connected to the air outlet. An exhaust pipe 5 is connected to the end of the connecting pipe 6 away from the housing 1. An air inlet pipe 7 is connected to the side wall of the dust hopper 2.

[0020] The outer shell 1 is constructed entirely of cold-rolled steel plate and welded together. Its outer wall undergoes powder coating for corrosion protection, enabling it to withstand the high humidity and high fiber dust conditions of textile workshops for extended periods. The bottom of the shell 1 connects to an inverted conical dust hopper 2 via a flange. The cone angle of the dust hopper 2 is set at 60 degrees, perfectly suited to the sliding characteristics of textile fiber dust, preventing bridging and accumulation of fiber material on the inner wall of the dust hopper 2. Four high-strength steel supports 3 are fixedly connected to the outside of the dust hopper 2 by welding, providing a stable support foundation for the entire machine. The bag cage 13 uses a galvanized circular steel wire frame, with each rib rounded to prevent sharp edges from scratching and damaging the cloth bag. The bag cage 13 is encased in an anti-static polyester needle-punched felt bag, effectively preventing safety hazards caused by static electricity generated from friction between textile fiber dust. Adjacent rows of bag cages 13 are completely separated by vertically arranged partitions 14. The partitions 14 divide the filtration space inside the housing 1 into multiple independent dust collection chambers, each corresponding to one row of filter bags. This allows for separate online dust cleaning of each chamber without affecting the normal filtration operation of other chambers. A moving mechanism is fixedly installed on the inner wall of the housing 1 below the bag cages 13. The overall layout of the moving mechanism perfectly matches the bottom position of the partitions 14, allowing for precise alignment with the bottom openings of any two adjacent partitions 14. A jet-blowing mechanism covering all chambers is installed on the top of the housing 1, with all nozzles 12 aligned with the top opening of each bag cage 13. The lower side wall of the ash hopper 2 is provided with a dust-laden air inlet, which is connected to the air inlet pipe 7. The air inlet end of the air inlet pipe 7 is detachably connected to a static pressure box 8. The static pressure box 8 is fixed to the air inlet pipe 7 by a flange. It is equipped with multiple layers of flow guide grids inside, which can evenly decelerate the high-speed dust-laden airflow collected from the textile workshop, avoid the high-speed airflow directly washing the filter bag and causing local wear, and greatly extend the service life of the filter bag.

[0021] Further refining the scheme, the moving mechanism includes four vertical rods 15 fixedly connected to the inner wall of the housing 1. Two horizontal rods 16 are provided inside the housing 1. The two ends of the horizontal rods 16 are fixedly connected to the vertical rods 15. A slider 18 is installed on the horizontal rod 16. The slider 18 can move along the horizontal rod 16. A hydraulic cylinder 28 is embedded in the slider 18. A sealing box 19 is fixedly connected to the output end of the hydraulic cylinder 28. A protruding plate 20 is symmetrically fixedly connected to the top of the sealing box 19. The distance between the two protruding plates 20 is consistent with the distance between the two adjacent partitions 14. A pipe 17 is connected to the bottom of the sealing box 19. The bottom of the pipe 17 is located below the air inlet pipe 7.

[0022] Specifically, the main body of the moving mechanism consists of four vertical rods 15 and two horizontal rods 16. The four vertical rods 15 are fixedly connected to the four corners of the inner wall of the housing 1 by bolts. The two horizontal rods 16 are arranged parallel to each other in the lower area of ​​the compartment. The two ends of the horizontal rods 16 are welded and fixed to the corresponding two vertical rods 15 to form a stable support structure. This structure can drive the sealing box 19 to move precisely between the bottoms of all compartments, significantly reducing the overall manufacturing cost and maintenance difficulty of the equipment. Each horizontal rod 16 is fitted with a slider 18 that can move along the axial direction of the rod. A waterproof hydraulic cylinder 28 is embedded inside the slider 18. The cylinder body of the hydraulic cylinder 28 is completely sealed inside the slider 18, and the output end extends vertically upward from the top surface of the slider 18 and is fixedly connected to the bottom surface of the sealing box 19. The sealing box 19 adopts a square box structure and has a slope on the inner bottom surface. A pipe 17 is connected to the center of the bottom of the sealing box 19. The material blown down by the blowing mechanism is sent into the ash hopper 2 through the pipe 17, which will not interfere with the normal airflow of the air inlet pipe 7 and prevent the dust from being disturbed by the rising airflow and thus forming secondary adsorption.

[0023] Further refining the design, a groove 29 is provided on the top surface of the crossbar 16, and a connector 30 is slidably connected in the groove 29. The connector 30 is fixedly connected to the slider 18. Hollow grooves 35 are symmetrically provided in the crossbar 16. Both ends of the connector 30 extend into the hollow grooves 35 and are slidably connected to the hollow grooves 35. A drive assembly is installed in the hollow grooves 35, and the drive assembly is connected to the connector 30 in a transmission manner.

[0024] Specifically, the crossbar 16 has symmetrically enclosed hollow grooves 35 on its left and right sides. The two ends of the connector 30 extend downward from the slide groove 29 and enter the hollow grooves 35 on both sides respectively, forming a sliding fit with the groove wall of the hollow groove 35. A drive assembly is installed inside the hollow groove 35. The drive assembly forms a stable transmission connection with the end of the connector 30 that extends into the groove, driving the connector 30 to make linear reciprocating motion along the hollow groove 35, thereby driving the sealing box 19 to move, which facilitates the cleaning of different compartments.

[0025] Further refining the scheme, the drive component includes a motor 33 fixedly connected to the inner wall of the hollow groove 35, and a lead screw 34 fixedly connected to the output shaft of the motor 33. The lead screw 34 passes through the connector 30 and is threadedly connected to the connector 30.

[0026] Specifically, the motor 33 is a waterproof servo motor 33. The motor 33 is fixedly connected to the inner wall end face of the hollow groove 35 by bolts. The output shaft of the motor 33 is fixedly connected to the high-precision ball screw 34 by a coupling. The rod of the screw 34 is arranged along the length of the hollow groove 35. The rod of the screw 34 passes through the end of the connector 30 laterally and forms a threaded transmission engagement with the connector 30. The forward and reverse rotation of the motor 33 can drive the connector 30 and the slider 18 to make precise linear movements along the crossbar 16 through the screw 34.

[0027] Further refining the design, a guide cone 31 is fixedly connected inside the crossbar 16. The tip of the guide cone 31 is located directly below the slide groove 29. The connector 30 is located above the guide cone 31. Inclined channels 32 extending through to the bottom of the crossbar 16 are provided on both sides of the guide cone 31.

[0028] Specifically, the connector 30 is always located above the guide cone 31 during movement. The left and right sides of the guide cone 31 are respectively provided with inclined channels 32 that extend to the bottom of the crossbar 16. The inner wall of the channel is polished. A small amount of fiber dust that accidentally falls into the crossbar 16 can slide directly into the ash hopper 2 below through the inclined channel 32, and will not accumulate inside the crossbar 16 to cause the component to jam.

[0029] To further refine the design, a cavity is provided at the bottom of the partition 14, and a movable plate 21 is slidably connected inside the cavity. The movable plate 21 is adapted to the protruding plate 20. Springs 22 are symmetrically arranged inside the cavity. One end of the spring 22 is fixedly connected to the top surface inside the cavity, and the other end of the spring 22 is fixedly connected to the movable plate 21. A second sensor 27 is arranged at the center of the movable plate 21, and a first sensor 25 is arranged at the center of the top surface inside the cavity. When the first sensor 25 contacts the second sensor 27, the blowing mechanism is activated.

[0030] Specifically, each partition 14 has a closed cavity at its bottom along its length. A movable plate 21 is slidably connected inside the cavity. The dimensions of the movable plate 21 perfectly match the space between the two protruding plates 20 on the top of the sealed box 19. Two springs 22 are symmetrically arranged on the left and right sides inside the cavity. When no external force is applied, the springs 22 will push the movable plate 21 downward to the bottom surface of the partition 14. The first sensor 25 and the second sensor 27 are non-contact photoelectric sensors. When the two protruding plates 20 push the movable plate 21 upward, so that the positions of the first sensor 25 and the second sensor 27 are completely aligned, the sensor will send an electrical signal to the external control system, automatically triggering the blowing mechanism above the corresponding compartment to start the dust removal action.

[0031] Further refining the scheme, a mounting base 24 is fixedly connected to the top surface of the cavity, and the bottom of the mounting base 24 is fixedly connected to the first sensor 25. A sleeve 23 is fixedly connected to the top surface of the movable plate 21, and a groove 26 is provided inside the sleeve 23. The second sensor 27 is located inside the groove 26, and the mounting base 24 is adapted to the groove 26.

[0032] Specifically, the mounting base 24 adopts a cylindrical metal base structure. The bottom of the mounting base 24 is fixed to the first sensor 25 by countersunk bolts. The top surface of the movable plate 21 has an integrally formed downward recessed sleeve 23. The sleeve 23 has a circular groove 26 inside. The second sensor 27 is completely embedded in the groove 26. The outer dimensions of the mounting base 24 are perfectly matched with the inner diameter of the groove 26. When the movable plate 21 moves upward, the mounting base 24 can be accurately inserted into the groove 26, ensuring that the alignment accuracy of the two sensors will not be offset.

[0033] Further refining the scheme, the blowing mechanism includes an air compressor 9 fixedly connected to the outside of the housing 1. Several blowing pipes 11 are connected to the air compressor 9. A pulse valve 10 is provided at one end of the blowing pipe 11 near the air compressor 9. Several nozzles 12 are connected to the bottom of the blowing pipe 11. Several nozzles 12 are arranged in a one-to-one correspondence with several bag cages 13.

[0034] Specifically, the high-pressure air source of the blowing mechanism comes from a screw air compressor 9 fixedly installed on the outside of the housing 1. The air outlet of the air compressor 9 is connected to multiple independent blowing pipes 11. Each blowing pipe 11 corresponds to an independent dust removal chamber. Each blowing pipe 11 is equipped with a high-frequency pulse valve 10 at the end near the air compressor 9. Multiple nozzles 12 are connected at equal intervals along the length of the pipe at the bottom of the blowing pipe 11. The position of each nozzle 12 is directly opposite to the top opening of the bag cage 13 in the corresponding chamber. After the pulse valve 10 is opened, the high-pressure airflow can be instantly injected into the inside of the filter bag to quickly shake off the fiber dust attached to the outer surface of the filter bag.

[0035] To further refine the design, a guardrail 4 is installed on the outside of the shell 1.

[0036] Specifically, a safety guardrail 4 is also fixedly installed on the top periphery of the shell 1 by welding, which makes it convenient for operators to stand on the top of the shell 1 to carry out daily maintenance and repair of the blowing mechanism and air compressor 9, and avoid the risk of falling from height.

[0037] The design is further refined, with a static pressure box 8 detachably connected to the intake pipe 7.

[0038] Specifically, the static pressure box 8 is equipped with multiple layers of guide grids, which can evenly slow down the high-speed dust-laden airflow collected from the textile workshop, avoid the high-speed airflow directly washing over the filter bags and causing local wear, and greatly extend the service life of the filter bags.

[0039] Working principle: The airflow containing fiber dust generated in the textile workshop is first decelerated and guided by the static pressure box 8 at the front end of the air inlet pipe 7. The uniform and low-speed dust-laden airflow enters the dust hopper 2 from the air inlet pipe 7. Large-diameter fiber dust particles settle directly to the bottom of the dust hopper 2 under gravity. Fine fiber dust particles rise with the airflow and enter each independent dust removal chamber. The airflow passes through the pores of the filter bag to complete filtration and purification. The fiber dust is intercepted and adheres to the outer surface of the filter bag. The purified air passes through the filter bag and enters the bag cage 13. It flows upward and is discharged from the outlet through the connecting pipe 6 and the exhaust pipe 5, and finally meets the emission standards and is discharged outside the workshop. When the thickness of the fiber dust adhering to the outer surface of the filter bag in a certain compartment reaches a preset threshold, and the resistance sensor inside the compartment detects that the pressure difference in the compartment exceeds the set value, the external control system starts the motor 33 of the drive component, which drives the connecting piece 30 and the slider 18 to move along the crossbar 16 through the lead screw 34, precisely moving the sealing box 19 to the position directly below the compartment to be cleaned. Then, the hydraulic cylinder 28 is activated to lift the sealing box 19 upwards as a whole. The two protruding plates 20 on the top of the sealing box 19 are simultaneously inserted between the two partitions 14 at the bottom of the corresponding compartment, completely sealing the bottom air inlet channel of the compartment. At the same time, the two protruding plates 20 move towards... The movable plate 21 at the bottom of the partition 14 is lifted. Overcoming the elastic force of the spring 22, the movable plate 21 slides upwards along the cavity until the second sensor 27 on the top surface of the movable plate 21 is completely aligned with the first sensor 25 on the top surface of the cavity. The sensor sends a trigger signal to the control system, instantly opening the pulse valve 10 above the corresponding compartment. The high-pressure airflow output by the air compressor 9 is sprayed at high speed into the filter bag through the nozzle 12 on the blowpipe 11. The filter bag expands and shakes instantly, shaking off all the fiber dust adhering to the outer surface into the sealing box 19, which then falls into the ash hopper 2 through the pipe 17 at the bottom of the sealing box 19, completing the online dust removal operation. After dust removal, the hydraulic cylinder 28 drives the sealing box 19 downwards, and the movable plate 21 automatically resets downwards under the elastic force of the spring 22. The entire dust removal process does not affect the continuous filtration operation of other compartments.
