Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a multi-cylinder dust collector unit. Background Technology

[0002] Textile factories produce clothing and other fabric products. When producing winter clothing, cotton is needed to fill the inside of the garments, which generates a lot of dust during the production process. The air inside the factory has a high content of solid particles, which is harmful to workers who work in the factory for long periods of time. Therefore, dust removal equipment is needed to remove dust from the air inside the factory. In order to speed up the dust removal process, existing technologies mostly use multi-cylinder dust collectors.

[0003] However, current dust removal units generally have an inconvenient structure, with the air filter screens located inside the unit, making subsequent disassembly very difficult. Furthermore, after the filter screens come into contact with the air, the dust remaining on the screens can easily fly outwards and be inhaled by maintenance personnel, causing discomfort and indoor pollution. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a multi-cylinder dust collector unit, in which the filter element can be opened and closed through the opening of the cylinder, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a multi-cylinder dust collector unit, including a main pipe, multiple cylinders and filter bags. The cylinders are all installed on the main pipe, and the openings of the cylinders are bent. The filter bags are all placed inside the cylinders. A tube is installed on the opening end of each filter bag. The end of the tube away from the filter bag extends to the opening of the cylinder and expands to form a tightening part. An annular elastic band is installed inside the tightening part. An air inlet pipe that expands the collection part outward is inserted inside the tightening part. A fixing part protrudes from each cylinder and a disassembly and assembly mechanism is installed on the fixing part to drive the air inlet pipe to move and press the tightening part.

[0006] As a preferred technical solution, the disassembly and assembly mechanism includes a push plate, a slider, a handle, and multiple compression springs. The outer side of the fixed part is provided with a sliding groove. The push plate is fitted to the fixed part. One end of the push plate is bent and installed on the air intake pipe. The slider is slidably disposed in the sliding groove. The outer side of the slider is installed on the push plate. The compression spring is disposed inside the sliding groove. One end of the compression spring is installed on the inner wall of the sliding groove, and the other end is installed on the slider.

[0007] As a preferred technical solution, a limiting ring is installed on the inner wall surface of the cylinder opening, and one end face of the tightening part is abutted against the limiting ring. The opening end of the air inlet pipe protrudes outward to form a ring-shaped limiting part, and one end face of the limiting part is abutted against the other end face of the tightening part.

[0008] As a preferred technical solution, the main pipe is provided with an air extraction hole at the position opposite the cylinder, and an air suction pump is installed at one end of the main pipe.

[0009] As a preferred technical solution, multiple bases are installed on the main pipe.

[0010] As a preferred technical solution, the tube body is made of multiple layers of fabric.

[0011] As a preferred technical solution, both the slider and the groove have trapezoidal cross-sections.

[0012] As a preferred technical solution, the filter bags are all positioned away from the opening of the cylinder.

[0013] The beneficial effects of this utility model are as follows: This utility model has a simple structure. After the air inlet pipe is pulled out, the opening of the pipe body can be contracted by the retraction of the annular elastic band, thereby blocking the dust inside the filter bag from being exposed as much as possible. After the air inlet pipe is pulled out, the filter bag can be directly taken out of the cylinder through the pipe body, which facilitates disassembly and replacement. After the filter bag is put into the cylinder, the opening of the pipe body can be opened by the inserted air inlet pipe, allowing air to enter the filter bag smoothly. Moreover, the filter bag is set away from the opening of the cylinder, reducing the probability of internal dust being exposed. Attached Figure Description

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a multi-cylinder dust collector unit, including a main pipe 1, multiple cylinders 2, and filter bags 12. The cylinders 2 are all installed on the main pipe 1, and the openings of the cylinders 2 are bent. The filter bags 12 are all disposed inside the cylinders 2. A tube 13 is installed on the open end of each filter bag 12. The end of the tube 13 away from the filter bag 12 extends to the opening of the cylinder 2 and expands to form a tightening part 16. An annular elastic band 17 is installed inside each tightening part 16. An air inlet pipe 5 is inserted into the tightening part 16 to expand the collection part outward. A fixing part 6 protrudes from each cylinder 2, and a disassembly and assembly mechanism is installed on each fixing part 6 to drive the air inlet pipe 5 to move and press the tightening part 16.

[0024] In this embodiment, the disassembly and assembly mechanism includes a push plate 7, a slider 14, a grip 8, and multiple compression springs 15. The outer side of the fixing part 6 is provided with a sliding groove. The push plate 7 is fitted to the fixing part 6. One end of the push plate 7 is bent and installed on the air intake pipe 5. The sliders 14 are slidably disposed in the sliding groove. The outer side of the sliders 14 is installed on the push plate 7. The compression springs 15 are disposed inside the sliding groove. One end of the compression springs 15 is installed on the inner wall of the sliding groove, and the other end is installed on the slider 14. The grip 8 is installed on the outer side of the push plate 7.

[0025] In this embodiment, a limiting ring is installed on the inner wall surface of the opening of the cylinder 2, and one end face of the tightening part 16 is in contact with the limiting ring. The opening end of the air inlet pipe 5 protrudes outward to form a ring-shaped limiting part, and one end face of the limiting part is in contact with the other end face of the tightening part 16.

[0026] In this embodiment, the main pipe 1 is provided with an air extraction hole 11 at the position opposite the cylinder 2, and an air suction pump 9 is installed at one end of the main pipe 1.

[0027] In this embodiment, multiple bases 3 are installed on the main pipe 1, which allows the device to be placed on the ground.

[0028] In this embodiment, the tube body 13 is made of multiple layers of fabric, which increases its strength and allows the tightening part to be smoothly closed inward through the fabric.

[0029] In this embodiment, both the slider 14 and the slide groove have trapezoidal cross-sections, which allows the slider to move back and forth along the slide groove, thus preventing the slider from detaching from the slide groove.

[0030] In this embodiment, the filter bags 12 are all located away from the opening of the cylinder 2, so that the impurities inside the filter bags are far away from the opening, reducing the probability of exposure.

[0031] When in use, start the suction pump. The suction force generated by the suction pump acts on the main pipe, and the main pipe creates negative pressure suction in the cylinder through the air extraction hole. Because the filter bag is equipped with a large number of filter holes, the external cavity can enter the pipe body and filter bag through the air inlet pipe. The filter bag can intercept dust, impurities and other particles in the air.

[0032] As impurities increase inside the filter bag, the push plate can be pushed outward by the handle. The movement of the push plate drives the air inlet pipe. After the air inlet pipe moves out of the opening of the pipe body, the retraction of the annular elastic band can cause the tightening part to contract inward, thereby sealing the opening of the pipe body. This prevents the dust inside the filter bag from being exposed as much as possible, and the filter bag can be pulled out directly, making it easy to disassemble. The tapered pipe body also makes it easy to move the filter bag to the treatment box, reducing the possibility of dust exposure during the journey.

[0033] During installation, the filter bag is first placed into the cylinder and moved to the vertical end of the cylinder. The filter bag is positioned away from the opening of the cylinder to reduce the probability of internal dust exposure. The tube is placed in the opening of the cylinder, with one end of the winding part abutting against the limiting part. After the tightening part is opened, the air inlet pipe can be inserted into the tightening part and opened. As the air inlet pipe is inserted, the limiting part abuts against the other end of the tightening part to ensure the stability of the tube after installation.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
