Detailed Embodiments

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model;

[0023] Refer to Figures 1-4 , a power-free dust removal and purification device for a gas film bin, which includes a dust removal box 1. A plurality of legs 2 are fixedly installed at equal intervals on the circumference of the bottom of the dust removal box 1. The bottom ends of the plurality of legs 2 are fixedly installed with a bottom plate 3; a sewage discharge pipe 11 is fixedly installed in the middle of the bottom of the dust removal box 1. An air inlet assembly is fixedly installed on one side of the dust removal box 1. An air outlet pipe 4 is fixedly installed on the top of the dust removal box 1. An installation ring 8 is fixedly installed inside the dust removal box 1. The dust removal box 1 is slidably installed with a filter assembly 9 through the installation ring 8.

[0024] One end of the air inlet assembly can be connected to the gas film bin. After the air inlet assembly is opened, since the inside of the gas film bin is at positive pressure (+300 pa), the gas inside the gas film bin will automatically flow into the inside of the dust removal box 1. The entering gas can be filtered through the filter assembly 9, and the filtered gas will be discharged through the filter assembly 9. The sewage discharge pipe 11 can discharge the dust and the like that fall during filtration.

[0025] The air inlet assembly includes an electric air duct valve 7, an air inlet pipe 6 and a connection bin 5. The connection bin 5 is fixedly installed below one side of the dust removal box 1. One end of the air inlet pipe 6 is fixedly connected to one side of the connection bin 5. The other end of the air inlet pipe 6 is fixedly installed with an electric air duct valve 7.

[0026] The electric air duct valve 7 can be connected to the gas film bin. After the electric air duct valve 7 is opened, the gas inside the gas film bin can enter the air inlet pipe 6. The inner diameter of the connection bin 5 is larger than the inner diameter of the air inlet pipe 6. The gas entering the inside of the connection bin 5 can reduce the flow rate and increase the gas pressure inside the dust removal box 1, so that the gas can push the filter assembly 9 upward and pass through the filter assembly 9.

[0027] The filter assembly 9 includes an installation sleeve 12 and a filter bag 13. The installation ring 8 is sleeved on the outside of the installation sleeve 12. A support bracket 15 is fixedly installed inside the installation sleeve 12. The installation sleeve 12 is installed with a filter bag 13 through the support bracket 15. An anti-detachment bracket 14 is fixedly installed at the top end of the installation sleeve 12. The anti-detachment bracket 14 covers the outside of the filter bag 13. The filter bag 13 is sleeved on the outside of the support bracket 15.

[0028] The anti-detachment bracket 14 is installed at the top end of the installation sleeve 12 through bolts and nuts, and the disassembly of the anti-detachment bracket 14 can be realized. The anti-detachment bracket 14 can prevent the filter bag 13 from falling off the outside of the support bracket 15. The filter bag 13 can filter the gas inside the dust removal box 1. The gas can pass through the filter bag 13 and be discharged through the air outlet pipe 4 after being filtered.

[0029] The top and bottom of the installation sleeve 12 are both provided with convex edges, and the two convex edges are respectively located on the upper and lower sides of the installation ring 8. A dirt collecting groove 10 is fixedly installed at the bottom inside the dust removal box 1. The sewage discharge pipe 11 is communicated with the dirt collecting groove 10, and the inner diameter of the dirt collecting groove 10 gradually decreases from top to bottom. The bottom end of the sewage discharge pipe 11 is threadedly installed with a detachable sealing cover.

[0030] As the dust inside the filter bag 13 gradually accumulates, the gas inside the dust removal box 1 can lift the filter assembly 9. By regularly opening and closing the electric air duct valve 7, the filter assembly 9 can be continuously lifted and lowered. When the filter assembly 9 falls, the convex edge at the upper end of the installation sleeve 12 will impact the installation ring 8. Under the action of impact and inertia, the dust inside the filter bag 13 will be shaken off and fall into the dirt collecting groove 10. The staff can open the sealing cover to discharge and clean the dust in the dirt collecting groove 10.

[0031] Through the continuous falling impact of the filter assembly 9, self-cleaning of the filter bag 13 can be realized, effectively reducing the replacement frequency of the filter bag 13 and reducing the possibility of complete blockage of the filter bag 13.
