Description

Technical Field

[0001] This utility model relates to the field of waste gas dust removal technology, and in particular to a waste gas dust removal device with an anti-clogging structure. Background Technology

[0002] Industrial waste gas dust removal is a crucial step in air pollution control, and physical methods such as mechanical, filtration, or electrostatic methods are commonly used to separate particulate matter from gases. Baghouse dust collectors rely on fiber filter media to intercept dust, cyclone dust collectors utilize centrifugal force to separate dust and gas, while wet scrubbers capture particles through droplets or liquid films. These devices use induced draft fans to drive the dust-laden airflow. The captured dust is collected in a dust hopper and periodically discharged, while the purified gas is emitted through a chimney after meeting emission standards. These systems are widely used in high-efficiency dust removal applications in industries such as metallurgy, building materials, and chemicals.

[0003] However, existing box-type exhaust gas dust collectors have the following drawbacks: after long-term use, the dust collection components inside the box are prone to clogging, and the device lacks an active anti-clogging structure, requiring personnel to disassemble the exhaust gas dust collector for maintenance. Frequent disassembly and maintenance affect work efficiency. Therefore, further improvements are needed. To this end, we propose an exhaust gas dust collector with an anti-clogging structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, a dust removal device for exhaust gas with an anti-clogging structure is disclosed, including a housing 1. An air inlet 2 and an air outlet 3 are respectively provided on both sides of the housing 1. A dust removal component 4 is vertically arranged inside the housing 1. The dust removal component 4 includes a frame plate 41. A filter cloth 42 is fixed inside the frame plate 41. A bottom opening 6 is provided on the bottom wall of the housing 1. The bottom opening 6 is located on the side near the air inlet 2. A dust collection hopper 7 is fixed at the bottom of the bottom opening 6. A beater component 9 is installed inside the housing 1 and on the side near the air outlet 3. The beater component 9 includes a horizontal shaft 91 that is rotatably connected to the side wall of the housing 1. A sleeve 95 is fitted on the surface of the horizontal shaft 91, and a plurality of beater strips 96 are fixed on the surface of the sleeve 95. An opening is provided on the side wall of the housing 1 near the dust removal component 4 and the beater component 9. A side cover 10 is installed inside the opening by bolts.

[0025] The air inlet 2 is connected to the exhaust gas pipe. After the exhaust gas enters the box 1 through the air inlet 2, the dust particles in the exhaust gas are intercepted by the filter cloth 42 and fall into the dust collection hopper 7 under the action of gravity. The filtered exhaust gas is discharged from the air outlet 3 and enters the next treatment process.

[0026] Multiple columns 11 are fixed to the lower surface of the housing 1, and the bottom ends of the multiple columns 11 are fixedly connected to a base plate 12. Mounting holes can be provided on the side of the base plate 12 for fixing and installing the dust removal device.

[0027] Two limiting plates 5 are fixed to the top wall of the inner chamber 1, and the top of the frame plate 41 is slidably engaged between the two limiting plates 5. When installing the dust removal component 4, the dust removal component 4 is inserted from the open side, and the top of the frame plate 41 slides between the two limiting plates 5 to achieve the limiting and fixing of the frame plate 41. When disassembling, the frame plate 41 can be directly pulled out from the open side for replacement.

[0028] A sealing strip is fixed to the outer wall of the frame plate 41, and the sealing strip is in contact with the inner wall of the box body 1 and the side cover 10.

[0029] After the frame plate 41 is installed inside the housing 1, the sealing strip can ensure the sealing between the frame plate 41 and the housing 1 and the side cover 10, and prevent dust from passing through the gaps on the side of the frame plate 41.

[0030] The bottom of the dust collection hopper 7 is equipped with a removable bottom cover 8. The bottom cover 8 can be opened periodically to discharge the dust collected inside the dust collection hopper 7.

[0031] A motor is installed on the outside of the housing 1 on the side away from the side cover 10. The horizontal shaft 91 is fixedly connected to the output end of the motor. A protruding rib 92 is fixed on the surface of the horizontal shaft 91. A keyway is provided on the inner wall of the sleeve 95 to engage the protruding rib 92. The beater strip 96 on one side of the sleeve 95 contacts the filter cloth 42.

[0032] After the motor is started, it drives the horizontal shaft 91 to rotate. The horizontal shaft 91 then drives the sleeve 95 and the beating strip 96 on the surface of the sleeve 95 to rotate. The beating strip 96 is made of high-temperature resistant soft plastic. When the beating strip 96 rotates to one side of the frame plate 41, it beats the filter cloth 42, causing the dust adhering to the surface of the filter cloth 42 to fall into the dust collection hopper 7, thus preventing the filter cloth 42 from clogging and affecting the flow of exhaust gas. The motor can be started at a time by setting a PLC controller.

[0033] A baffle 93 is fixed to one end of the horizontal shaft 91 near the motor. The other end of the horizontal shaft 91 is provided with an external thread, and an internal thread cap 94 is rotatably connected to the external thread surface. The sleeve 95 is located between the internal thread cap 94 and the baffle 93.

[0034] The sleeve 95 and the beater bar 96 are an integral structure and can be replaced as a whole. When replacing them, first remove the side cover 10, then unscrew the internal thread cap 94, and pull the sleeve 95 off the surface of the horizontal shaft 91. The sleeve 95 and the beater bar 96 are taken out as a whole from the open side. Replace the new sleeve 95 and the beater bar 96, put the new sleeve 95 on the surface of the horizontal shaft 91, and the protrusion 92 on the surface of the horizontal shaft 91 is locked in the keyway on the inner wall of the sleeve 95. Finally, screw the internal thread cap 94 on the external thread surface of the horizontal shaft 91.

[0035] Working principle: During the waste gas treatment process, dust-laden gas enters the housing 1 through the inlet 2. The dust is intercepted by the filter cloth 42 of the dust removal component 4, and the purified gas is discharged through the outlet 3. The intercepted dust falls into the dust collection hopper 7 under gravity. When the beater component 9 is working, the motor drives the horizontal shaft 91 to rotate, which in turn drives the sleeve 95 and the beater strips 96 on it to rotate. The soft beater strips 96 periodically beat the surface of the filter cloth 42, shaking off the attached dust and causing it to fall into the dust collection hopper 7, preventing the filter cloth 42 from clogging. When it is necessary to clean the dust, the bottom cover 8 at the bottom of the dust collection hopper 7 can be opened for centralized discharge. When replacing the dust removal component 4, the side cover 10 can be removed to pull the frame plate 41 out from between the limiting plates 5; when replacing the sleeve 95 of the beater component 9, after removing the side cover 10, the internal thread cap 94 can be unscrewed, and the sleeve 95 and the beater strips 96 can be removed from the horizontal shaft 91 as a whole for replacement.
