There are generally two types of dust collectors on the top of the silo: bags and filters. The bag dust collector has a frameless hanging bag structure inside. When the bags are used for three months, the bags become hardened, which affects the dust removal effect on site, causing serious dust accumulation on site and polluting the environment. When replacing the bags, the operators need to enter the bag silo. The working space is small.

[0028] Example

[0029] The specific implementation of the utility model is as follows Figures 1 to 6 As shown, a small-sized single-volume dust bin dust removal device comprises a housing 1 having a dust suction port 13 at the lower end, and the dust suction port 13 is provided with a mounting portion 12 for detachably connecting to the top of the dust bin 7. A partition plate 2 is provided inside the housing 1, and the partition plate 2 divides the inner cavity of the housing 1 into an upper cavity 15 and a lower cavity 14 arranged upper and lower, respectively. A through hole 21 is provided on the partition plate 2, and a bag cage 6 corresponding to the through hole 21 is connected to the bottom of the partition plate 2, and a cloth bag 4 is sleeved on the outer side of the bag cage 6. An induced draft fan 3 connected to the upper cavity 15 is installed on the housing 1, and an air outlet 31 is provided on the induced draft fan 3. A back-blowing mechanism 5 matching the inner side of the bag cage 6 is also connected to the housing 1.

[0030] The back-blowing mechanism 5 includes a back-blowing gas storage tank 51, a main gas pipe 52 and a back-blowing pipe 53 connected in sequence. The back-blowing gas storage tank 51 is installed on the outside of the shell 1, the main gas pipe 52 penetrates the upper cavity 15 of the shell 1, and the gas outlet end of the back-blowing pipe 53 passes through the through hole 21 of the partition plate 2 and is located inside the bag cage 6. A valve controlled by a controller is provided on the main gas pipe 52. In this embodiment, a plurality of bag cages 6 and cloth bags 4 are provided on the bottom surface of the partition plate 2.

[0031] The upper end of the bag cage 6 is detachably connected to the partition plate 2. In this embodiment, the bag cage 6 includes at least two vertical rods 61 and a plurality of circular rings 62, and each vertical rod 61 is connected to the circular ring 62. A plug-in portion 63 protruding from the side wall is provided at the top of the vertical rod 61, and a pressure plate 64 is connected to the upper part of the bag cage 6, and the pressure plate 64 is located below the plug-in portion 63 and the two are arranged at intervals. The partition plate 2 is provided with at least two plug-in holes 22 arranged around the center of the through hole 21, and a card slot 23 is provided on the same side of each plug-in hole 22. The plug-in portion 63 is plug-fitted with the plug-in hole 22. The card slot 23 is slidably fitted with the upper part of the vertical rod 61. The plug-in portion 63 and the pressure plate 64 are respectively located on the upper and lower sides of the partition plate 2.

[0032] When the bag cage 6 needs to be installed, the plug-in portion 63 at the upper end of the vertical rod 61 is passed through the plug-in hole 22 from bottom to top, so that the plug-in portion 63 is located above the partition plate 2, and then the bag cage 6 is rotated as a whole to allow the upper part of the vertical rod 61 to slide into the slot 23. At this time, the plug-in portion 63 and the plug-in hole 22 can be staggered up and down, and the plug-in portion 63 and the pressure plate 64 are respectively located on the upper and lower sides of the partition plate 2, thereby realizing the connection between the partition plate 2 and the bag cage 6.

[0033] A sealing ring 65 in contact with the lower surface of the partition plate 2 is disposed on the upper surface of the pressure plate 64. The through hole 21, the plug hole 22 and the card slot 23 are all located inside the sealing ring 65 to prevent dust from passing through the partition plate and entering the upper cavity.

[0034] An elastic hoop 41 is provided at the top opening of the cloth bag 4, and the elastic hoop 41 is sleeved between the pressure plate 64 and the topmost circular ring 62. The circular ring 62 is located outside each vertical rod 61. When the cloth bag 4 needs to be removed from the bag cage 6, the elastic hoop 41 is opened, and the cloth bag 4 can be pulled downward out of the bag cage 6.

[0035] The lower part of the housing 1 comprises an inverted conical body 11, and the dust suction port 13 and the mounting portion 12 are both located at the lower end of the inverted conical body 11. The mounting portion 12 adopts a flange structure.

[0036] like Figure 6 As shown, when using a small single-volume dust bin dust removal device, the mounting portion 12 of the housing 1 is fixed to the top of the dust bin 7 by screws, and a reserved opening is provided on the top of the dust bin 7 so that the inner cavity of the dust bin 7 is connected to the lower cavity 14 of the housing 1. A door body may be provided on the side wall of the lower cavity 14 of the housing 1, and the bag cage 6 and the cloth bag 4 can be installed and removed by opening the door body.

[0037] The dust-laden gas enters the lower cavity 14 of the outer shell 1 from the reserved opening at the top of the dust bin 7. The induced draft fan 3 is turned on to draw out the airflow. The fine dust particles are blocked on the outer wall of the bag 4 due to the various efficiency effects of the bag 4. The purified gas is discharged through the air outlet 31. With the increase of use, the dust adsorbed on the surface of the bag 4 increases, the air permeability of the bag 4 weakens, and the resistance of the dust removal device continues to increase. In order to ensure that the resistance of the dust removal device is controlled within a specified range, the pulse controller sends a signal to sequentially open the electromagnetic pulse valve, so that the compressed air in the back-blowing air storage tank 51 is ejected from the back-blowing pipe 53 into the corresponding bag cage 6. After the high-speed airflow enters the bag, the bag 4 expands rapidly. Since the impact of the reverse pulse airflow disappears quickly, the bag 4 contracts rapidly again, so that the dust attached to the outer wall of the bag is removed, and the fallen dust enters the dust bin 7.

[0038] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
