Description

Technical Field

[0001] The utility model relates to the technical field of pulse dust collectors, in particular to a pulse dust collector which is easy to maintain. Background Art

[0002] A dust collector is a dry dust filtering device. During the operation of a bag dust collector, dust will continue to accumulate on the surface of the filter bag due to effects such as screening, collision, retention, diffusion, and static electricity, resulting in increased resistance and reduced filtration efficiency. When the resistance of the filter bag reaches a certain value, it needs to be cleaned to ensure the dust removal effect.

[0003] Generally, the filter bags on pulse dust collectors are fixed. When they are damaged after long-term use, it is difficult to repair them in time. During maintenance, it is also troublesome to replace the filter bags, and they cannot be replaced conveniently, which delays the progress of maintenance. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a pulse dust collector that is easy to maintain, which can conveniently replace the filter bag and is also easy to maintain.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-5 The utility model discloses a pulse dust collector that is easy to maintain, comprising a pulse dust collector housing 1 and a door body 2 arranged on the side wall of the pulse dust collector housing 1, a material discharge channel 3 is connected to the lower end of the pulse dust collector housing 1, a support leg 4 is arranged at the lower end of the pulse dust collector housing 1, a first partition plate 6 and a second partition plate 9 are respectively fixedly installed on the inner cavity side walls of the pulse dust collector housing 1, and a plurality of filter bags 5 are respectively arranged between the first partition plate 6 and the second partition plate 9;

[0025] The first partition plate 6 and the second partition plate 9 are provided with positioning components 7 for facilitating the installation of the filter bag 5 . The pulse dust collector housing 1 is also provided with a scraping component 8 for scraping the bottom surface of the filter bag 5 .

[0026] The positioning assembly 7 includes a connecting ring 71 fixedly installed on the upper end of the positioning assembly 7 and a connecting block 72 fixedly installed on the side wall of the connecting ring 71. An installation chamber 76 is opened on the first partition plate 6. A through-slot 79 is connected to the installation chamber 76. An annular groove 73 is connected to the side wall of the through-slot 79. The position of the connecting ring 71 and the connecting block 72 can be limited by the setting of the annular groove 73. The installation is convenient and the operation is simple. The connecting block 72 is slidably set in the annular groove 73, and the lower end of the filter bag 5 is inserted into the second partition plate 9.

[0027] An iron ring 77 is fixedly installed on the lower end of the second partition plate 9, and a sleeve 86 is fixedly installed on the lower end of the second partition plate 9. A magnet ring 78 is arranged on the inner cavity side wall of the sleeve 86. The magnet ring 78 is magnetically attracted to the iron ring 77. Through the cooperation of the magnet ring 78 and the iron ring 77, the lower end of the filter bag 5 can be conveniently limited.

[0028] A plurality of first springs 75 are fixedly mounted on the top wall of the mounting chamber 76 . The first springs 75 are in a natural state in an initial state. A top plate 74 is fixedly mounted on the lower ends of the plurality of first springs 75 . The top plate 74 is located on one side of the connecting ring 71 .

[0029] When it is necessary to install the filter bag 5, first insert the connecting ring 71 and the connecting block 72 at the upper end of the filter bag 5 into the insertion slot 79, the connecting ring 71 will squeeze the top plate 74, and then rotate the connecting ring 71 and the connecting block 72 so that the two are rotated into the corresponding annular grooves 73. Through the setting of the annular grooves 73, the longitudinal positions of the connecting ring 71 and the connecting block 72 can be limited. In the process where the connecting ring 71 squeezes the top plate 74, the top plate 74 squeezes the first spring 75 at the corresponding position. Through the elastic force of the first spring 75, the top plate 74 squeezes the connecting ring 71 to limit it again and ensure that the upper end of the filter bag 5 will not be displaced. At this time, the iron ring 77 at the lower end of the filter bag 5 contacts the magnet ring 78, and the two attract each other, thereby realizing the limiting of the lower end of the filter bag 5.

[0030] When the filter bag 5 needs to be repaired and disassembled, it is only necessary to rotate the connecting ring 71 and the connecting block 72 again to rotate the connecting block 72 to a position corresponding to the through-slot 79. At this time, the top plate 74 will be subjected to the elastic force of the first spring 75, and the top plate 74 will push out the connecting block 72 and the filter bag 5 together, so that they are separated from the first partition plate 6.

[0031] Reference Figure 2 and Figure 4 The scraping assembly 8 includes a plurality of U-shaped panels 81 fixedly mounted on the second partition plate 9 and a trapezoidal sleeve 82 fixedly mounted on the lower end of the magnet ring 78. The filter bag 5 is inserted into the corresponding U-shaped panel 81. A connecting groove 83 is provided on the inner cavity side wall of the sleeve 86. The magnet ring 78 is slidably arranged on the connecting groove 83. The U-shaped panel 81 is composed of a plurality of panels stacked together. As can be seen from 2, this arrangement can conveniently scrape the surface of the filter bag 5 without being seriously blocked by dust.

[0032] A slide bar 84 is fixedly mounted on the bottom wall of the connecting groove 83 , and a second spring 85 is sleeved on the slide bar 84 . Two ends of the second spring 85 are fixedly connected to the bottom wall of the connecting groove 83 and the bottom wall of the magnet ring 78 , respectively.

[0033] When wind blows into the filter bag 5 (it should be noted that the blowing of wind toward the filter bag 5 by equipment is a prior art and is not shown), it will blow downward along it. When the wind passes through the trapezoidal sleeve 82, it will give the filter bag 5 a certain resistance. The trapezoidal sleeve 82 will drive the magnet ring 78, the iron ring 77 and the filter bag 5 to move downward together. The two ends of the magnet ring 78 will slide along the slide bar 84 and squeeze the second spring 85 at the corresponding position. In the process of downward displacement, the filter bag 5 will move along several U-shaped panels 81. In the process of movement, the dust attached to the surface of the filter bag 5 can be cleaned in time and will not be supported on its surface for a long time. It can be cleaned conveniently. When the wind stops blowing, the filter bag 5 will be restored to its initial position by the elastic force of the second spring 85. In this process, the filter bag 5 will be vibrated again, which can further make the dust on its surface fall off and extend its service life.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
