[0029] When the present embodiment is used, when it is necessary to use the flat bag dust collector to work, the rotating plate 431 in the lifting assembly 43 of the purification treatment device 4 is rotated, and the rotating plate 431 drives the screw 432 to rotate. The screw 432 is connected to the lifting box 42 by a bearing, and the screw 432 is threadedly connected to the connecting tube 41, and the outer side of the lifting box 42 is close to the inner side of the connecting tube 41, so the screw 432 drives the lifting box 42 to move until the lifting box 42 and other structures move between the conveying pipe 3 and the fan assembly 5, and the fan assembly 5 is operated to suck the gas into the dust removal box 1 through the air inlet pipe 6, and the flat bag passes through The filter assembly 9 filters the dust therein, and then the gas passes through the conveying pipe 3 and the ventilation net 45 to contact the activated carbon 44, and then the gas passes through another ventilation net 45 and the fan assembly 5 to be discharged, and the fan assembly 5 is turned off, and the work is completed. When necessary, the staff can blow air to the flat bag filter assembly 9 through the backblowing cleaning assembly 2 to remove the dust thereon, and the staff can discharge the dust through the ash discharge assembly 7. When necessary, the staff can unscrew the blocking block 46 to replace the activated carbon 44, and can observe the condition of the activated carbon 44 through the observation window 47 when necessary.

[0030] Example 2

[0031] The present embodiment is different from the embodiment 1 in that the temporary storage device 8 includes a connecting frame 81, a storage box 83 and a connecting pipe 84, the connecting pipe 84 is installed below the ash discharge assembly 7, the connecting frame 81 is installed below the connecting pipe 84, and the storage box 83 is arranged on the inner side of the connecting frame 81.

[0032] By adopting the above technical solution, the dust collector can temporarily store the dust discharged from the dust discharge assembly 7 through the cooperation of structures such as the storage box 83 and the connecting pipe 84 when needed, so as to better meet the working needs in different situations.

[0033] Specifically, the temporary storage device 8 further includes a spring pin 82 , and the spring pin 82 is installed at the bottom of the connecting frame 81 .

[0035] When this embodiment is used, when it is necessary to temporarily store the removed dust, the storage box 83 in the temporary storage device 8 is placed in the connecting frame 81, and the position of the storage box 83 is limited by the spring pin 82. When the ash discharge component 7 discharges ash, the dust will pass through the connecting pipe 84 and fall into the storage box 83, thereby being temporarily stored to better meet the work needs in different situations.

[0036] The structure and principle of the dust removal box 1 and its upper structure, the back-blowing cleaning component 2 composed of an air storage tank, a blowing pipe and an electromagnetic pulse valve, the fan component 5 composed of an air outlet pipe and a dust exhaust fan, the air inlet pipe 6, the ash outlet component 7 composed of an ash hopper and an ash outlet, and the flat bag filter component 9 composed of a U-shaped mounting part, a flower plate, a stepped square hole, a filter bag assembly and a rectangular frame in the utility model have been disclosed in a rotary back-blowing flat bag dust collector for easy bag replacement disclosed in Chinese patent application No. 201920402379.7. The working principle is that when replacing the filter bag, only the plug door needs to be pulled out, the flower plate needs to be taken out through the U-shaped mounting part, and then the filter bag needs to be taken out through the attraction between the square iron ring on the bag cage and the square magnetic ring on the filter bag. The rectangular frame can prevent dust from adhering to the inner wall of the dust removal box, which is convenient for repair and maintenance of the dust removal box in the later stage. A star-shaped ash discharge valve is installed at the bottom of the ash outlet to facilitate the discharge of smoke in the ash hopper.

[0037] The working principle and use process of the utility model: when it is necessary to use the flat bag dust collector to work, rotate the rotating plate 431 in the lifting assembly 43 in the purification treatment device 4, and the rotating plate 431 drives the screw 432 to rotate, the screw 432 and the lifting box 42 are connected by a bearing, and the screw 432 and the connecting tube 41 are threadedly connected, and the outer side of the lifting box 42 is close to the inner side of the connecting tube 41, so the screw 432 drives the lifting box 42 to move until the lifting box 42 and other structures move between the conveying pipe 3 and the fan assembly 5, operate the fan assembly 5, and suck the gas into the dust removal box 1 through the air inlet pipe 6, the flat bag filter assembly 9 filters the dust therein, and then the gas passes through the conveying pipe 3 and the ventilation net 45 to contact the activated carbon 44, and then the gas passes through another ventilation net 45 and the fan assembly 5 are discharged, and the fan assembly 5 is turned off. When necessary, the staff can blow air to the flat bag filter assembly 9 through the backblowing cleaning assembly 2 to remove the dust thereon, and the staff can discharge the dust through the ash discharge assembly 7. When necessary, the staff can unscrew the blocking block 46 to replace the activated carbon 44, and can observe the condition of the activated carbon 44 through the observation window 47 when necessary; when it is necessary to temporarily store the removed dust, the storage box 83 in the temporary storage device 8 is placed in the connecting frame 81, and the position of the storage box 83 is limited by the spring pin 82. When the ash discharge assembly 7 discharges ash, the dust will pass through the connecting pipe 84 and fall into the storage box 83, so as to be temporarily stored, so as to better meet the work needs in different situations.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
