Embodiment 1

[0057] An automatic declogging waste gas filter device, such as figure 1 , 2 As shown, it includes an intake pipeline 1 and a purification pipeline 2, wherein the intake pipeline 1 and the purification pipeline 2 communicate with the cleaning filter mechanism 3, and the cleaning filter mechanism 3 includes: an air inlet 31, an air outlet 32, and a chute 33. Vibration head 4, sliding block 5, negative pressure port 34, connecting ring 6, filter unit 7, sealing plate 9.

[0058] The intake pipe 1 is provided with a suction mechanism for attracting exhaust gas, the air inlet 31 is connected to one end of the intake pipe 1, the other end of the intake pipe 1 is connected to the exhaust gas spray tower (not shown), and the air outlet 32 ​​is connected to the purification Pipeline 2, after the clean gas pipeline, the gas can be measured, if it meets the emission standard, it can be discharged, if it still does not meet the emission standard, the next step of cleaning can be carried...

Embodiment 2

[0072] An automatic declogging waste gas filtering device has the same characteristic structure as that of Embodiment 1, wherein, such as Figure 7 As shown, the cleaning filter mechanism 3 also includes: a trigger lever 20 , a pressure spring 21 , a blocking plate 22 , and an air pressure tube 30 .

[0073] The trigger lever 20 is arranged at the right end position of the chute 33 , and the trigger lever 20 is provided with a pressure spring 21 . Blocking plate 22 links to each other with the right end of trigger lever 20, and blocking plate 22 passes through the air pressure block, and blocking plate 22 is used for blocking off the communication of air pressure pipe 30 and the space where filter unit 7 is located, and there is a pair on the left side of blocking plate 22. The interface 23 is used to communicate with the air pressure tube 30 after the blocking plate 22 moves to the right. The pneumatic tube 30 has a pneumatic head towards the filter unit 7 .

[0074] Such a...

Embodiment 3

[0076] An automatic plugging method, wherein, comprising the following steps:

[0077] The exhaust gas is introduced into the clean filter mechanism 3 through the intake pipeline 1, and after the exhaust gas enters from the air inlet 31 of the clean filter mechanism 3, the particulate matter in the exhaust gas is filtered through the filter unit 7;

[0078] When the filter unit 7 has filtered and accumulated a large amount of particles for a long time, the exhaust gas is difficult to be filtered by the filter unit 7, and the filter unit 7 is under the pressure of the exhaust gas, pushing the connecting ring 6 and the sliding block 5 connected with the connecting ring 6 to the right along the chute 33 Sliding, sliding block 5 makes negative pressure port 34 open, and is no longer blocked by sliding block 5, and the sliding pull stay cord 91 of sliding block 5 moves simultaneously, makes the sealing plate 9 rotations of air inlet 31 places, and air inlet 31 for sealing;

Abstract

The invention discloses an automatic blockage-clearing waste gas filtering device and relates to the technical field of waste gas clearing equipment. The device comprises a cleaning and filtering mechanism; the cleaning and filtering mechanism comprises a sliding chute, a vibration head, a sliding block, a negative pressure port, a connecting ring, a filtering unit and a sealing plate; the filtering unit accumulating a large number of particles slides rightwards after bearing enough waste gas pressure; firstly, a sliding block on the side of the filtering unit is in butt joint with a vibrationblock, so that the filtering unit is affected by high-frequency vibration, and the particles on the filtering unit are rapidly shaken off; and secondly, after the sliding block moves, the negative pressure port is opened to suck and clean the shaken-off particles, so that secondary adsorption is avoided; and thirdly, after the sliding block moves, the sealing plate can be pulled to seal an air inlet, so that waste gas accumulates pressure in the air inlet, and when the pressure is enough, the sealing plate is pushed away, the sliding block is reset, and waste gas continues to be filtered. Automatic cleaning of the filtering unit after the filtering unit accumulates the particles is facilitated, manual intervention is not needed, and the waste gas filtering efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of waste gas cleaning equipment, in particular to an automatic blockage cleaning waste gas filter device. Background technique [0002] Industrial pollution refers to the pollution of the environment by waste gas, waste water and solid discharges formed in the process of industrial production. Pollution is mainly caused by "three wastes" (waste water, waste gas, waste residue) and various noises in production, which can be divided into waste water pollution, waste gas pollution, waste residue pollution, and noise pollution. Among them, industrial waste gas pollution. With the rapid development of industry, a large amount of waste gas will be generated in industrial production. If it cannot be properly treated, it will be discharged into the air, which will not only pollute the environment, but also seriously endanger human health. [0003] In order to be able to effectively treat industrial waste gas, the m...
