Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to an integrated jet cleaning device for a dust collector. Background Technology

[0002] In environments with special dust, such as aluminum plant electrolytic cells, pharmaceutical raw material crushing, and chemical catalyst regeneration, bag filters are often used to purify dust-laden gases. Among them, the pulse jet cleaning pipe, as the core component of the bag filter's pulse jet cleaning system, is responsible for the crucial task of precisely guiding the high-pressure pulse airflow ejected from the pulse valve through the nozzles on the pipe body to the inside of each filter bag. After the cleaning command is issued, the pulse valve opens, and compressed air enters the pulse jet pipe in a pulse form. It is then injected into the filter bag at high speed through the nozzles, inducing the surrounding air to form a secondary airflow, causing the filter bag to expand and vibrate instantly, effectively peeling off the surface dust layer.

[0003] Currently, most blowpipes adopt a conventional design of "straight pipe body + equidistant straight holes". That is, the main body is a straight metal pipe, and circular straight holes perpendicular to the axis of the pipe body are opened according to the spacing of the filter bags. Each nozzle corresponds to the center of a filter bag. Although this structure is easy to manufacture, because the nozzles are linearly and equidistantly distributed and the spray direction is perpendicular to the pipe body, when the pulse valve is opened, the high-speed airflow from adjacent nozzles will collide with each other above the filter bag inlet, forming a vortex zone. This airflow collision phenomenon reduces the effective airflow that actually enters the filter bag, reduces the dust removal efficiency on the filter bag surface, and affects the overall dust removal effect.

[0029] like Figures 1 to 6 As shown, an integrated jet cleaning device for a dust collector includes a jet pipe body 1. Multiple connecting pipes 2 are fixedly connected to the bottom of the jet pipe body 1. The connecting pipes 2 are evenly distributed and communicate with the jet pipe body 1. A venturi tube 3 is slidably connected to the lower end of the connecting pipe 2. The diameter of the upper end of the venturi tube 3 is larger than the diameter of the lower end of the venturi tube 3.

[0030] The dust collector of this utility model uses an integrated jet cleaning device. By setting equidistant connecting pipes 2 at the bottom of the jet pipe body 1 and sleeved with a venturi tube 3 that is thicker at the top and thinner at the bottom, it replaces the traditional straight hole structure. This can guide the airflow to be concentrated and sprayed into the filter bag, avoid the collision of adjacent airflows to form vortices, increase the effective airflow into the filter bag, improve the dust removal efficiency on the surface of the filter bag, and solve the problem of poor dust removal effect of traditional jet pipes.

[0031] In some embodiments, a front mounting block 4 is fixedly connected to one end of the blowpipe body 1, a front mounting frame 5 is slidably connected to the side of the front mounting block 4 away from the blowpipe body 1, and a first bolt 6 is slidably connected to both sides of the front mounting block 4. The first bolt 6 passes through the front mounting block 4 and is threadedly connected to the front mounting frame 5. Mounting plates 7 are fixedly connected to both sides of the other end of the blowpipe body 1. A rear mounting frame 8 is provided at the bottom of the mounting plate 7. A plurality of second bolts 9 are slidably connected to the middle position of the mounting plate 7. The second bolts 9 pass through the mounting plate 7 and the rear mounting frame 8 and are threadedly connected to the nut.

[0032] Furthermore, the front mounting block 4 is slidably connected to the front mounting frame 5 and fixed by the first bolt 6, and the mounting plate 7 is connected to the rear mounting frame 8 by the second bolt 9, making the main body of the blowpipe 1 easier and more convenient to install, ensuring precise alignment with the filter bag, avoiding airflow misalignment caused by installation deviation, reducing eddy formation, and improving dust removal efficiency.

[0033] In some embodiments, the upper end of the venturi tube 3 is provided with a cover plate 10, and the cover plate 10 is fixedly connected to the venturi tube 3.

[0034] Building upon this, in traditional dust collectors, during backflushing, some airflow diffuses outwards from the nozzles (especially areas far from the nozzles), resulting in incomplete cleaning of the bottom or edges of the filter bags. This device, however, is equipped with a cover plate 10, which can cover the top of the filter bags during backflushing, forcing the airflow to flow axially along the filter bags, reducing lateral diffusion, and allowing the airflow to act more concentratedly on the dust layer inside the filter bags, thereby improving airflow utilization.

[0035] In some embodiments, connecting blocks 11 are fixedly connected to the four corners of the top of the cover plate 10, and a lifting frame 12 is slidably connected to the upper end of the connecting blocks 11.

[0036] Furthermore, the top of the cover plate 10 is connected to the lifting frame 12 via the connecting block 11, which facilitates the simultaneous lifting of multiple venturi tubes 3, reduces the hassle of operating them one by one, improves maintenance efficiency, and ensures the continuous and stable operation of the device.

[0037] In some embodiments, slide plates 14 are fixedly connected to both sides of the lifting frame 12, slide rods 15 are slidably connected to the middle position of slide plates 14, insert plates 16 are fixedly connected to the bottom of slide rods 15, chamfers are provided on the periphery of the bottom of insert plates 16, and baffles 13 matching insert plates 16 are fixedly connected to the side wall of connecting block 11.

[0038] Furthermore, the lifting frame 12, slide plate 14, slide bar 15, insert plate 16, connecting block 11 and baffle 13 cooperate with each other to make the connection between the lifting frame 12 and the connecting block 11 more stable, prevent loosening, ensure the stability of the venturi tube 3, prevent the airflow direction from deviating, and maintain the dust removal effect.

[0039] In some embodiments, the top of the slide bar 15 is provided with a grip plate 17, and the two ends of the grip plate 17 are respectively fixedly connected to two slide bars 15 located on the same side of the lifting frame 12.

[0040] Furthermore, by using the grip plate 17 to pull the slide bar 15 located on the same side of the lifting frame 12, it is more effortless and convenient.

[0041] In some embodiments, a spring 18 is sleeved on the upper end of the slide bar 15, one end of the spring 18 is fixedly connected to the grip plate 17, and the other end of the spring 18 is fixedly connected to the slide plate 14.

[0042] Furthermore, the spring 18 always has a downward pulling force to prevent the insert plate 16 from moving upward on its own, which would cause the insert plate 16 to detach from the baffle 13.

[0043] In some embodiments, a dust cover 19 is fixedly connected to the side of the slide plate 14 away from the lifting frame 12, and the dust cover 19 is sleeved on the outside of the spring 18.

[0044] Furthermore, a dust cover 19 is provided on the side of the slide plate 14 to prevent dust from entering the spring 18 and causing the spring 18 to jam, ensuring the normal reset function of the spring 18, extending the life of the component, maintaining the stability of the device, and reducing the occurrence of failures.

[0045] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
