Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 5 As shown, an anti-clogging ultra-low emission filter bag of the utility model comprises: a dust removal box 1, a box door 10 is hinged on the outer surface of one side of the dust removal box 1, and also comprises an ash hopper 11, which is movably arranged on the inner bottom surface of the dust removal box 1, and the inner surface of the dust removal box 1 is fixedly provided with a support frame 12 in the horizontal direction, and the bottom surface of the support frame 12 is detachably installed with a plurality of filter bag rolls 13, and the plurality of filter bag rolls 13 are all compatible with the ash hopper 11; a fan 15, a fixing frame 14 is fixedly arranged on the bottom surface of the fan 15, and the four side outer surfaces of the fixing frame 14 are fixedly connected to the four side inner surfaces of the dust removal box 1 respectively.

[0028] Through the above-mentioned structural design, when the fan 15 draws smoke with sticky solid particles through the extension pipe 20 into the dust removal box 1 before contacting the filter bag roll 13, the filter screen 29 installed by the installation mechanism 3 is convenient for preventing sticky solid particles from entering. The hole diameter of the filter screen 29 is larger than the hole diameter of the filter bag roll 13, which allows smoke with solid particles to pass through, but the double-layer filter screen 29 is convenient for adhering to sticky solid particles, so that a large number of sticky solid particles will not adhere to the surface of the filter bag roll 13, which will facilitate the use of the vibration principle to clean the dust on the surface of the filter bag inside the dust removal box 1, thereby improving the service life and use effect of the filter bag inside the dust collector. When the smoke with dust enters the dust removal box 1, under the action of the filter bag roll 13, the smoke will be filtered so that the dust falls into the ash hopper 11, which is convenient for purifying the smoke and protecting the environment.

[0029] The filtering mechanism 2 comprises an extension pipe 20, and the extension pipe 20 is fixedly connected to the external smoke pipe, one end of the extension pipe 20 is fixedly connected to a sealing block 21, one side outer surface of the sealing block 21 is fixedly connected to a connecting pipe 22, and one end of the connecting pipe 22 away from the sealing block 21 is fixedly connected to one side inner surface of the dust removal box 1, a movable rod 23 is rotatably passed through the outer surface of one side of the connecting pipe 22, and an adjustment plate 24 is fixedly provided on the outer surface of one side of the movable rod 23, a limiting screw 26 is fixedly provided on the outer surface of one side of the connecting pipe 22, a movable plate 25 is fixedly provided on the outer surface of one side of the movable rod 23, and the movable plate 25 is adapted to the limiting screw 26, two grooves 210 are provided on the outer surface of one side of the sealing block 21, and the inner bottom surfaces of the two grooves 210 are fixedly provided with limiting blocks 211, four positioning rods 212 are fixedly provided on the inner bottom surface of the sealing block 21, and the outer surfaces of the four positioning rods 212 are disassembled and installed with the mounting mechanism 3.

[0030] Through the above-mentioned structural design, the external flue gas can easily enter the extension pipe 20, and the flue gas in the extension pipe 20 can easily enter the connecting pipe 22 after being purified by the installation mechanism 3. The flue gas preliminarily purified in the connecting pipe 22 can easily enter the dust removal box 1. In the process of flue gas flow, the movable plate 25 is rotated by external force to facilitate the rotation of the movable rod 23, and the rotation of the movable rod 23 is convenient to drive the adjustment plate 24 to rotate, which will facilitate the control of the flow rate of flue gas.

[0031] The mounting mechanism 3 includes a mounting block 30, and both sides of the mounting block 30 have engaging grooves 35 on their outer surfaces, and the inner surfaces of the two engaging grooves 35 are fixedly provided with fixing rods 36, and the outer surfaces of the fixing rods 36 are detachably provided with rubber rings 27, and the mounting tube 28 is detachably provided between the opposite surfaces of the two rubber rings 27, and both ends of the mounting tube 28 are fixedly provided with filter screens 29, and the two filter screens 29 are respectively matched with the water outlet end of the extension pipe 20 and the water inlet end of the connecting pipe 22, a fixing plate 32 is fixedly provided on the top surface of the mounting block 30, and a handle 34 is fixedly provided on the top surface of the fixing plate 32 near the center, and two limiting grooves 33 are provided on the bottom surface of the fixing plate 32, and the two limiting grooves 33 are respectively matched with the two limiting blocks 211, and four positioning grooves 31 are provided on the bottom of the mounting block 30, and the four positioning grooves 31 are respectively matched with the four positioning rods 212.

[0032] Through the above structural design, the engaging groove 35 and the fixing rod 36 facilitate the stable installation of the rubber ring 27. The rubber ring 27 facilitates the sealing of the mounting block 30 with the connecting pipe 22 and the extension pipe 20. The mounting pipe 28 facilitates the installation of the filter screen 29. The filter screen 29 facilitates the adhesion of sticky solid particles. When the amount of solid particles in the flue gas is large, only the filter screen 29 on one side of the connecting pipe 22 is installed, and the frequency of replacing the mounting pipe 28 and the filter screen 29 is increased. Working principle: When using the anti-clogging ultra-low emission filter bag, when the fan 15 draws smoke with sticky solid particles through the extension pipe 20 into the dust removal box 1 before contacting the filter bag roll 13, the filter screen 29 facilitates the prevention of sticky solid particles from entering. When the smoke with dust enters the dust removal box 1, the filter bag roll 13 will filter the flue gas and make the dust fall into the ash hopper 11. When it is necessary to replace the filter screen 29 with a large amount of sticky solid particles, the handle 34 is used to pull the fixing plate 32 to move. The movement of the fixing plate 32 facilitates the driving of the mounting block 3 0 moves, when the mounting block 30 is away from the sealing block 21, the rubber ring 27 and the mounting tube 28 provided with the filter screen 29 are taken out by external force, and the mounting tube 28 is cleaned or taken out with a new one and inserted into the mounting block 30. After the installation is completed, the mounting block 30 is inserted by using the limit block 211 and the positioning rod 212, which will facilitate the installation of the filter screen 29. The filter screen 29 is convenient for preventing sticky solid particles from entering, and it is convenient to use the vibration principle to clean the dust on the surface of the filter bag inside the dust removal box 1, thereby improving the service life and use effect of the filter bag roll 13 inside the dust removal box 1.
