Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bag dust removal, in particular to a high-efficiency bag dust collector. Background Art
[0002] The dust removal principle of the bag dust collector initially relies on inertial collision, diffusion, interception, and static electricity to form a primary dust layer, and then relies on the screening effect of the primary dust layer to filter and remove dust. When cleaning, it relies on gravity sedimentation to make the ash cake settle into the ash hopper to achieve the purpose of gas purification. During filtration, dust-laden gas enters from the bottom and is filtered by the outer surface of the filter bag. The purified airflow enters the inside of the filter bag and converges to the clean air chamber at the upper part for discharge. As the dust settles, the pressure loss of the filter bag continues to increase. When it reaches the predetermined value, the pulse valve works, compressed air is sprayed in, and a large amount of gas is induced to enter the inside of the filter bag, causing the filter bag to expand and deform, shake off the dust, and achieve the purpose of removing dust on the surface of the filter bag. The dust sinks into the ash hopper by gravity.
[0003] At present, the surface of the existing bag dust collector is usually provided with two openings, one is the air inlet and the other is the exhaust port. The staff inputs the flue gas to be treated into the interior of the bag dust collector through the exhaust port. Since the exhaust is only discharged into the interior of the bag dust collector through the exhaust port, the gas is easy to gather at the same position inside the bag dust collector, which is not conducive to the uniform diffusion of the gas inside the bag dust collector, and thus the gas cannot fully contact the dust bag, affecting the dust bag's filtering efficiency of the gas. Utility Model Content
[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a high-efficiency bag dust collector that can solve the problem that when exhaust is only discharged to the interior of the bag dust collector through the exhaust port, the gas tends to gather at the same position inside the bag dust collector, which is not conducive to the uniform diffusion of the gas inside the bag dust collector, and the gas cannot fully contact the dust collector bags.
[0005] To achieve the above object, the utility model provides the following technical solution: a high-efficiency bag dust collector, comprising a bag dust collector box, a dust collection bag is provided inside the bag dust collector box, an exhaust box is fixedly connected to the top of the bag dust collector box, an exhaust pipe is fixedly connected to the top of the exhaust box, and a sealing cover is rotatably connected to the top of the exhaust pipe;
[0006] Among them, the interior of the bag dust removal box is fixedly connected to a U-shaped air inlet pipe, and the interior of the U-shaped air inlet pipe is provided with an exhaust device.
[0007] Preferably, the bottom wall of the bag dust removal box is slidably connected to a dust collecting box.
[0008] Preferably, a back-blowing blower is fixedly connected to the top of the bag dust removal box, an exhaust port of the back-blowing blower is fixedly connected to an exhaust hose, and the exhaust hose is communicated with the interior of the exhaust box.
[0009] Preferably, the exhaust device includes an exhaust pipe, which is slidably sleeved inside the U-shaped air inlet pipe, and a blowing port is opened on the surface of the exhaust pipe. A sliding rod is fixedly connected to the surface of the exhaust pipe, and the surface of the sliding rod is in contact with the surface of the dust bag.
[0010] Preferably, a servo motor is provided on the top of the bag dust removal box, an output end of the servo motor is fixedly connected to a rotating shaft, and a slot is provided on the surface of the rotating shaft.
[0011] Preferably, a shaft sleeve is fixedly connected to the surface of the exhaust pipe, a positioning ball is fixedly connected to the inner wall of the shaft sleeve, and the surface of the positioning ball contacts the inner wall of the slot.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] (1) The high-efficiency bag dust collector rotates the rotating shaft and drives the positioning card ball and the shaft sleeve to slide up and down through the groove on the surface. The shaft sleeve slides up and down and drives the exhaust pipe to slide up and down and blows the gas evenly on the surface of the dust bag through the blowing port, preventing the gas from gathering at the same position inside the bag dust collector box. The gas is evenly diffused inside the bag dust collector box, thereby allowing the gas to fully contact the dust bag, thereby improving the dust bag's filtering efficiency for the gas.
[0014] (2) For this high-efficiency bag dust collector, the staff starts the back-blowing blower, which exhausts air into the exhaust box through the exhaust hose. The wind inside the exhaust box gradually increases and blows the dust bag in the opposite direction, causing it to expand and shake off the dust attached to the surface. The dust falls into the dust collecting box. At this time, the exhaust pipe slides up and down and drives the slide bar to slide and hit the surface of the dust bag, thereby improving the cleaning effect of the dust bag surface.

[0030] The air filter 12 is then filtered by the dust bag 2 and the filtered air gradually moves upward and enters the exhaust box 3 and is finally discharged to the outside through the exhaust pipe 4. After the staff starts the servo motor 13, the output end of the servo motor 13 rotates and drives the rotating shaft 14 to rotate.
