Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, an environment-friendly smoke filter bag in this embodiment includes an outer barrel 17, a discharge hopper 7 is fixedly connected to the bottom of the outer barrel 17, and a limit structure is installed on the top of the outer barrel 17.

Limit structure includes mounting panel 1, the inside fixed mounting of mounting panel 1 has outlet duct 2, the bottom fixedly connected with skeleton 3 of outlet duct 2, the outside fixed mounting of skeleton 3 has filter bag 4, mounting groove 10 has all been seted up to the inside left and right sides of mounting panel 1, the inside sliding connection of mounting groove 10 has briquetting 8, the equal fixedly connected spring 9 in one side of two briquetting 8 opposite directions, the bottom fixedly connected with connecting rod 15 of briquetting 8, the equal fixedly connected with gag lever post 13 in one side that two connecting rods 15 are relative, spacing groove 14 has all been seted up to the left and right sides of urceolus 17, peg graft in the inside of spacing groove 14 in gag lever post 13, the bottom fixed mounting of mounting panel 1 has locating ring board 11, locating groove 12 has been seted up at the top of urceolus 17, locating ring board 11 joint is in the inside of locating groove 12.

The limiting rod 13 is inserted into the limiting groove 14 through the elastic action of the spring 9 to play a role in locking, so that the filter bag 4 is convenient to install and detach.

In this embodiment, the right side of urceolus 17 runs through and is fixed with intake pipe 5, and the bottom fixedly connected with dust exhaust pipe 6 of ejection of compact fill 7 all installs the valve on intake pipe 5 and the dust exhaust pipe 6, and the cross-section of urceolus 17 is circular.

In this embodiment, a sealing ring is fixed on the inner wall of the positioning groove 12, and the positioning ring plate 11 is abutted against the sealing ring.

The sealing performance between the mounting plate 1 and the outer cylinder 17 is improved through the sealing ring, so that gas can only be discharged from the gas outlet pipe 2, and smoke dust is prevented from being discharged without being filtered by the filter bag 4, and the environment protection is ensured.

In this embodiment, a rectangular groove 16 communicated with the mounting groove 10 is formed at the bottom of the mounting plate 1, the bottom of the connecting rod 15 extends to the outside through the rectangular groove 16, and pull rings are fixedly connected to one sides of the two connecting rods 15 in opposite directions.
