[0021] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-3 The mobile exhaust dust filter shown includes a closed shell 1, and a plurality of evenly distributed moving wheels 2 are installed on the bottom surface of the shell 1. The moving wheels 2 are used to facilitate the movement of the shell 1. A partition 13 is provided inside the shell 1, and one side of the partition 13 is set as an air inlet bin 3, and the other side of the partition 13 is set as an air outlet bin 4. An air inlet group connected to the air inlet bin 3 is provided on the shell 1 away from the air outlet bin 4, and an air outlet group connected to the air outlet bin 4 is provided on the shell 1 away from the air inlet bin 3. A filter assembly connecting the air inlet bin 3 and the air outlet bin 4 is installed on the partition 13, and a recoil assembly matching the filter assembly is installed on the upper part of the shell 1. The recoil assembly can be used to recoil the filter assembly, which can effectively prevent dust from clogging the recoil assembly.

[0023] The filter assembly includes several dust filter cartridge groups, and the dust filter cartridge groups include several evenly distributed dust filter cartridges 7. The partition 13 is provided with a mounting hole for installing the dust filter cartridge 7. The dust filter cartridge 7 is inserted in the air inlet bin 3. The gas entering from the air inlet 5 enters the air inlet bin 3 and then enters the air outlet bin 4 through the dust filter barrel and is then discharged from the outer shell 1 through the air outlet 6. In this process, the design of inserting the dust filter cartridge 7 in the air inlet bin 3 can effectively increase the contact area between the gas entering the air inlet bin 3 from the air inlet 5 and the dust filter cartridge 7, which is beneficial to improving the filtration efficiency.

[0024] The recoil assembly includes an air bottle 8 fixedly mounted on the housing 1, a drain valve 14 is installed at the bottom of the air bottle 8, an air filter 9 is connected to one side of the air bottle 8, and a plurality of evenly distributed pulse valves 10 corresponding to the dust filter cartridge group are installed on the other side of the air bottle 8. The pulse valve 10 is connected to an air pipe 11, and the air pipe 11 extends into the housing 1 and cooperates with the corresponding dust filter cartridge group. The outside air enters the air bottle 8 after being filtered by the air filter 9, and the moisture in the air in the air bottle 8 is liquefied and accumulated at the bottom of the air bottle 8. When the moisture in the air bottle 8 accumulates to a certain amount, it is discharged through the drain valve 14 The air filtered by the air bottle 8 and the air filter 9 accumulates in the air bottle 8. When the pulse valve 10 is opened, the air in the air bottle 8 enters each dust filter cartridge 7 in the dust filter cartridge group through the air pipe 11 to recoil the dust filter cartridge 7. In this process, the air filter 9 cooperates with the air bottle 8 and uses the air filter 9 to filter the recoil air, which can prevent impurities from entering the dust filter cartridge 7 and preventing impurities from affecting the operation of subsequent equipment. Using the air bottle 8 to store the filtered air is beneficial to increasing the pressure in the air bottle 8, and can further expand the pressure difference between the air bottle 8 and the inside of the shell 1, which is beneficial to improving the recoil effect.

[0025] The air inlet group includes several air inlets 5 corresponding to the dust filter cartridge groups, and the air inlets 5 are located on the outer shell 1 in the middle of several dust filter cartridges 7 in the same dust filter cartridge group. The air outlet group includes several air outlets 6 corresponding to the dust filter cartridge groups, and the air outlets 6 are located on the outer shell 1 in the middle of several dust filter cartridges 7 in the same dust filter cartridge group. Each dust filter cartridge group corresponds to an air inlet 5 and an air outlet 6, which can enable the gas entering the outer shell 1 to quickly pass through the dust filter barrel, which is beneficial to improving the filtration efficiency.

[0026] Several branch pipes are installed in parallel on the air pipe 11, and the branch pipes are inserted in the center of the dust filter cartridge 7. The branch pipes can be used to allow the air in the air bottle 8 to enter different dust filter cartridges 7, thereby achieving backflushing of each dust filter cartridge 7.

[0027] The dust filter cartridge groups are provided with two groups, each of which is provided with two dust filter cartridges 7, two pulse valves 10 are provided, and the air bottle 8 is provided with a long straight bottle. The two pulse valves 10 are connected to both ends of the air bottle 8. The air bottle 8 between the two pulse valves 10 is provided with a connecting pipe connected to the air filter 9. The air bottle 8 adopts a long straight bottle design, so that the air entering the air bottle 8 moves from the middle to both sides, which is conducive to prolonging the residence time of the air in the air bottle 8, and is conducive to promoting the external air to enter the air bottle 8 and contact the bottle wall to liquefy the water vapor in the air, which can effectively reduce the moisture content in the recoil air and effectively prevent dust from adhering to the dust filter cartridge 7;

[0028] The air bottle 8 is also provided with a pressure relief valve, which can effectively prevent the air bottle 8 from being damaged due to excessive internal pressure.

[0029] A slag outlet 12 is provided on the shell 1 at the bottom of the air inlet bin 3 , and the slag outlet 12 can be used to clean the dust deposited at the bottom of the air inlet bin 3 out of the shell 1 in time.
