Description

Technical Field

An explosion-proof long bag low-pressure pulse dust collector comprises a bottom plate 1, a support rod 2 is fixedly connected to the top of the bottom plate 1, a limit frame 3 is fixedly connected to the top of the support rod 2, a protective block 4 is movably sleeved inside the limit frame 3, a bolt 5 is threadedly sleeved on the front of the limit frame 3, a dust box 6 is fixedly sleeved inside the limit frame 3, a partition 7 is fixedly sleeved inside the dust box 6, a filter bag tube 8 is fixedly sleeved at the bottom of the partition 7, a pulse tube 9 is fixedly sleeved inside the dust box 6, a nozzle 10 is fixedly installed at the bottom of the pulse tube 9, and a receiving hopper 11 is fixedly sleeved at the bottom of the dust box 6. A delivery pipe 12 is fixedly connected to the top of the base plate 1, a push block 13 is movably sleeved inside the delivery pipe 12, a rotating motor 14 is fixedly installed on the front of the delivery pipe 12, a threaded rod 15 is fixedly connected to the output shaft of the rotating motor 14, a sealing strip 16 is fixedly connected to the front of the delivery pipe 12, a sliding ball 17 is movably sleeved at the bottom of the inner cavity of the delivery pipe 12, a limiting mechanism 18 is arranged on the front of the inner wall of the delivery pipe 12, a pulse mechanism 19 is arranged on the side of the dust removal box 6, a moving mechanism 20 is arranged at the bottom of the base plate 1, and a guide cover 21 is fixedly connected to the side of the base plate 1.

[0026] The threaded rod 15 is threadedly sleeved on the inside of the pushing block 13, and the threaded rod 15 and the base plate 1 are parallel to each other; by setting the threaded rod 15, when the dust is cleared and needs to be discharged, the rotating motor 14 will be started, so that the rotating motor 14 can drive the pushing block 13 to move horizontally inside the conveying pipe 12 through the threaded rod 15. At this time, the dust inside the dust removal box 6 enters the conveying pipe 12 through the receiving hopper 11 and is pushed to the outside of the conveying pipe 12 by the pushing block 13, thereby solving the problem of low fluidity during dust discharge, which makes dust discharge more difficult, thereby improving the convenience of dust cleaning and transportation, that is, improving the dust removal efficiency.

[0027] There are two limit frames 3, and the two limit frames 3 are symmetrically distributed with the dust removal box 6 as the symmetry axis; by setting the limit frame 3, when the dust removal box 6 is installed and fixed, the dust removal box 6 is sleeved on the inside of the limit frame 3, and the bolt 5 is rotated at this time so that the bolt 5 can be tightly squeezed on the outside of the dust removal box 6, so that the dust removal box 6 can be fixed inside the limit frame 3, thereby facilitating the installation and fixation of the dust removal box 6.

[0028] There are several sliding balls 17, which are evenly distributed at the bottom of the inner cavity of the conveying pipe 12. By setting the sliding balls 17, when the dust is squeezed and pushed, the sliding balls 17 can support the horizontally moving pushing block 13, thereby avoiding the problem of friction between the pushing block 13 and the bottom of the inner cavity of the conveying pipe 12 when the pushing block 13 moves horizontally, thereby improving the smoothness of the dust removal and guidance.

[0029] The limiting mechanism 18 includes a limiting groove 181, which is opened on the front side of the inner wall of the conveying pipe 12. The limiting groove 181 is internally movably sleeved with a limiting block 182, and the limiting block 182 is fixedly connected to the outside of the pushing block 13. By setting the limiting mechanism 18, when the pushing block 13 moves horizontally to push the dust, the limiting block 182 is able to limit the position of the horizontally moving pushing block 13, thereby avoiding the problem of offset when the pushing block 13 moves horizontally.

[0030] The pulse mechanism 19 includes a support plate 191, which is fixedly connected to the side of the dust removal box 6, and an air pump 192 is fixedly installed on the top of the support plate 191, and a control host 193 is fixedly installed on the top of the support plate 191; by setting the pulse mechanism 19, when the dust on the surface of the filter bag tube 8 is cleaned, the control host 193 is started, so that the control host 193 can control the air pump 192 to start, and at this time the air pump 192 can impact the air flow inside the filter bag tube 8 through the pulse tube 9 and the nozzle 10, so that the filter bag tube 8 can vibrate, so that the dust adhered to the surface of the filter bag tube 8 can fall off to the inside of the receiving hopper 11, thereby achieving the cleaning effect of the surface of the filter bag tube 8, thereby bringing convenience to the cleaning of the dust.

[0031] The material of the protective block 4 is rubber material, and the number of the protective blocks 4 is two; by setting the protective block 4, when the dust removal box 6 is squeezed and fixed, the protective block 4 can greatly increase the friction between the bolt 5 and the dust removal box 6, thereby avoiding the problem of sliding and falling off when the dust removal box 6 vibrates, thereby improving the stability of the dust removal box 6 after being fixed.

[0032] The moving mechanism 20 includes a support column 201, which is fixedly connected to the bottom of the base plate 1, and a sliding wheel 202 is installed at the bottom of the support column 201; by setting the moving mechanism 20, when the position of the pulse dust collector is adjusted, the base plate 1 is pushed, so that the sliding wheel 202 can drive the base plate 1 to move horizontally through the support column 201, that is, drive the dust box 6 to move horizontally, thereby facilitating the adjustment of the working position of the pulse dust collector.

[0033] The guide cover 21 is made of stainless steel, and there are two guide covers 21, which are symmetrically distributed with the base plate 1 as the axis of symmetry. By setting the guide cover 21, when dust collection is required, the storage bag is sleeved inside the guide cover 21. At this time, the dust inside the conveying pipe 12 can enter the storage bag through the guide cover 21, thereby facilitating the collection and storage of dust.

[0034] The working principle of the explosion-proof long bag low-pressure pulse dust collector provided by the utility model is as follows:

[0035] The first step: first, when the dust is cleared and needs to be discharged, the rotating motor 14 will be started, so that the rotating motor 14 can drive the pushing block 13 to move horizontally inside the conveying pipe 12 through the threaded rod 15. At this time, the dust inside the dust box 6 enters the conveying pipe 12 through the receiving hopper 11 and is pushed to the outside of the conveying pipe 12 by the pushing block 13, thereby solving the problem of low fluidity during dust discharge, which makes dust discharge more difficult, thereby improving the convenience of dust cleaning and transportation, that is, improving the dust removal efficiency. When the dust box 6 is installed and fixed, the dust box 6 is sleeved on the inside of the limiting frame 3. At this time, the bolt 5 is rotated so that the bolt 5 is tightly squeezed on the outside of the dust box 6, so that the dust box 6 can be fixed inside the limiting frame 3, which brings convenience to the installation and fixation of the dust box 6. When the dust is squeezed and pushed, the sliding ball 17 can be The push block 13 that moves horizontally is supported, thereby avoiding the problem of friction between the push block 13 and the bottom of the inner cavity of the conveying pipe 12 when the push block 13 moves horizontally, thereby improving the fluency of dust removal and conveying. When the push block 13 moves horizontally to push the dust, the limit block 182 is able to limit the position of the horizontally moving push block 13, thereby avoiding the problem of deviation when the push block 13 moves horizontally. When cleaning the dust on the surface of the filter bag cylinder 8, the control host 193 is started, so that the control host 193 can control the air pump 192 to start. At this time, the air pump 192 can impact the air flow inside the filter bag cylinder 8 through the pulse tube 9 and the nozzle 10, thereby causing the filter bag cylinder 8 to vibrate, so that the dust adhered to the surface of the filter bag cylinder 8 can fall off to the inside of the receiving hopper 11, thereby achieving the cleaning effect of the surface of the filter bag cylinder 8, thereby bringing convenience to the cleaning of the dust;

[0036] Step 2: When the dust box 6 is squeezed and fixed, the protective block 4 can greatly increase the friction between the bolt 5 and the dust box 6, thereby avoiding the problem of sliding and falling off when the dust box 6 vibrates, thereby improving the stability of the dust box 6 after fixation. When adjusting the position of the pulse dust collector, the base plate 1 is pushed so that the sliding wheel 202 can drive the base plate 1 to move horizontally through the support column 201, that is, drive the dust box 6 to move horizontally, thereby facilitating the adjustment of the working position of the pulse dust collector. When dust collection is required, the storage bag is mounted inside the guide cover 21. At this time, the dust inside the conveying pipe 12 can enter the storage bag through the guide cover 21, thereby facilitating the collection and storage of dust.

[0037] Compared with the related art, the explosion-proof long bag low-pressure pulse dust collector provided by the utility model has the following beneficial effects:

[0038] By setting the threaded rod 15, when the dust is cleared and needs to be discharged, the rotating motor 14 will be started, so that the rotating motor 14 can drive the pushing block 13 to move horizontally inside the conveying pipe 12 through the threaded rod 15. At this time, the dust inside the dust removal box 6 enters the conveying pipe 12 through the receiving hopper 11 and is pushed to the outside of the conveying pipe 12 by the pushing block 13, thereby solving the problem of low fluidity during dust discharge, which makes dust discharge more difficult, thereby improving the convenience of dust cleaning and transportation, that is, improving the dust removal efficiency.
