Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology, and in particular to a cyclone-filter bag composite dust collector for dust collection in textile workshops. Background Technology

[0002] The textile production process generates a large amount of fiber dust and lint. This dust not only seriously affects the air quality in the workshop and threatens the health of workers, but its long-term accumulation may also cause safety hazards such as dust explosions. Cyclone dust collectors are effective at handling larger dust particles, but their removal efficiency for fine dust is relatively low. While bag filters have a high collection efficiency for fine dust, their maintenance costs are high. To achieve efficient dust removal, reduce operating and maintenance costs, and ensure workshop production safety, integrated cyclone and bag filter dust collectors are becoming increasingly popular.

[0003] Since the adsorbed dust is mostly fibrous or flocculent and may contain oily substances, it easily adheres to the surface of the filter bag, forming a "bag clogging" phenomenon. Even if the cyclone removes some large particles first, fine fibers may still penetrate the filter bag pores or accumulate in the gaps of the filter material, resulting in a sharp increase in filtration resistance, increased dust removal frequency, and shortened filter bag replacement cycle. In view of the above reasons, this application proposes a cyclone-filter bag composite dust collector for dust collection in textile workshops. Utility Model Content

[0044] Example

[0045] like Figure 1-5As shown, this utility model proposes a cyclone-bag filter composite dust collector for collecting dust in textile workshops. It includes a cyclone dust collector body 1 and a bag filter dust collector body 2. The tops of both the cyclone dust collector body 1 and the bag filter dust collector body 2 are respectively equipped with an inlet pipe 3 and an outlet pipe 6. Both the cyclone dust collector body 1 and the bag filter dust collector body 2 have dust hoppers at their bottoms. The top of the cyclone dust collector body 1 is equipped with an outlet pipe 4 for discharging air. One side of the bag filter dust collector body 2 is equipped with an inlet pipe 5. An electrostatic precipitator for removing oily substances from the dust is located between the outlet pipe 4 and the inlet pipe 5. The oil mist eliminator 7, also known as the electrostatic oil mist eliminator 7, can remove oily substances from dust and prevent the filter bag from sticking to oil and clogging. The electrostatic oil mist eliminator 7 is provided with an inlet pipe 8 and an outlet pipe 9 on both sides for guiding gas. The inlet pipe 8 and the outlet pipe 9 are both fixedly provided with a limiting strip 15 and a retaining ring 14. The ends of the inlet pipe 8 and the outlet pipe 9 that are far apart are both fixedly provided with an installation ring 16. A sealing gasket is fixedly provided on one side of the installation ring 16. The inlet pipe 8 and the outlet pipe 9 are fixedly connected to the outlet pipe 4 and the inlet pipe 5, respectively. The inlet pipe 8 and the outlet pipe 9 are both provided with a fixing structure 10 for quick installation.

[0046] The fixing structure 10 includes a connecting ring 101 for installation. The inner wall of the connecting ring 101 is provided with a limiting groove 109, which is movably connected to a limiting strip 15. Two mounting boxes 102 are fixedly provided on the outside of the connecting ring 101. Each mounting box 102 is movably provided with a positioning rod 103. Positioning rings 17 are fixedly provided on the outside of the air outlet pipe 4 and the air inlet pipe 5. The surface of the positioning ring 17 is provided with a hole, and the rod 103 is adapted to the hole. A locking block 106 is provided on one inner wall of the mounting box 102. A pull rod 105 is fixedly provided on one side of the first locking block 106. The pull rod 105 is movably connected to the mounting box 102. A limiting rod 107 is fixedly provided on one side of the first locking block 106. The two limiting rods 107 are movably connected to the mounting box 102. A second spring is sleeved on the pull rod 105. A second locking block 104 is fixedly provided on the outside of the insertion rod 103. The second locking block 104 and the first locking block 106 are both provided with parallel inclined surfaces on the side that are close to each other. A first spring 108 is provided on one side of the connecting ring 101. The other end of the first spring 108 is fixedly connected to the electrostatic oil mist remover 7.

[0047] The front of the filter bag dust collector body 2 is equipped with a PLC 11, and the top of the filter bag dust collector body 2 is fixed with an alarm light 13 and a filter bag resistance sensor 12. The filter bag resistance sensor 12 measures the pressure difference before and after the filter bag to reflect the degree of dust accumulation on the surface of the filter bag. The higher the resistance value, the more dust accumulates on the filter bag, the greater the filtration resistance, which may affect the system air volume.

[0048] In this embodiment, the electrostatic precipitator 7 can remove oily substances from dust and prevent the filter bag from becoming clogged with oil. Before use, push the two connecting rings 101 towards each other so that one end of the inlet pipe 8 and the outlet pipe 9 is exposed. Then, place the electrostatic precipitator 7 between the cyclone dust collector body 1 and the filter bag dust collector body 2, so that the end of the outlet pipe 4 and the inlet pipe 5 that are close to each other fits against the sealing gasket on one side of the two mounting rings 16. Then, loosen them. The two connecting rings 101 are pushed by the spring 108 and reset, and are fitted onto the outside of the two positioning rings 17. Then, press the two sets of insert rods 103 inward at the same time. The insert rods 103 drive the second locking block 104. The inclined surface of the second locking block 104 presses the first locking block 106. The first locking block 106 then presses the second spring on one side. When the two inclined surfaces separate, the second spring causes the first locking block 106 to reset and lock onto the top of the second locking block 104. The insertion rod 103 is positioned so that its lower end is inserted into the insertion hole on the surface of the positioning ring 17, thus installing the electrostatic oil mist eliminator 7. To disassemble, pull each pair of pull rods 105 to separate the first locking block 106 from the second locking block 104. Then, pull the insertion rod 103 outward to separate it from the insertion hole. Next, pull the two connecting rings 101 towards each other to expose the connection point between the inlet pipe 8, outlet pipe 9, outlet pipe 4, and inlet pipe 5. Finally, pull the electrostatic oil mist eliminator 7 outward to disassemble it. The filter bag resistance sensor 12 is located at the differential pressure monitoring point on both sides of the filter bag. It is used to monitor the pressure difference before and after the filter bag and feed the data back to the PLC 11. When the resistance value increases and does not decrease, the PLC 11 will activate the alarm light 13 to sound an alarm, reminding relevant personnel that the filter bag is blocked and that factors such as dust humidity and cleaning pressure need to be checked.

[0049] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
