Description

Technical Field

[0001] This utility model relates to the field of waste gas dust removal technology, specifically an atmospheric environment waste gas dust removal and cleaning device. Background Technology

[0002] Baghouse dust collectors filter dust particles from dust-laden gas through filter bags, thereby purifying the air. When dust-laden gas enters the dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. Gas containing finer dust particles passes through the filter bags, where the dust is trapped. The purified gas then escapes through the filter bags and is discharged through the exhaust pipe. The accumulated dust on the filter bags can be removed by reverse gas washing or pulse jet cleaning, thus achieving the purpose of dust removal. However, when the humidity content of the exhaust gas is high, the filtered dust will stick to the inner wall of the ash hopper. After a long period of accumulation, the outlet of the ash hopper will be blocked, resulting in poor filtration. Therefore, this patent proposes to design an atmospheric exhaust gas dust removal and cleaning device for cleaning the ash hopper. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0025] This application discloses an atmospheric waste gas dust removal and cleaning device. (Refer to...) Figure 1-7 An atmospheric waste gas dust removal and cleaning device includes a dust collector body 1, which includes a filter barrel 101. A dust removal cover 102 is fixedly connected to the top of the filter barrel 101 by bolts. An air outlet pipe 103 is connected to the inner cavity of the dust removal cover 102. An air inlet pipe 104 is connected to the surface of the filter barrel 101. A connecting ring 6 is fixedly connected to the bottom of the surface of the filter barrel 101. A lower connecting ring 109 is fixedly connected to the inner cavity of the connecting ring 6. A dust hopper 106 is installed at the bottom of the lower connecting ring 109. A cleaning mechanism 2 is installed on the surface of the filter barrel 101. A guiding mechanism 3 is installed in the inner cavity of the filter barrel 101.

[0026] The cleaning mechanism 2 includes a motor 203, which is fixedly connected to the surface of the filter bucket 101. A gear 204 is fixedly connected to the output end of the motor 203. A gear ring 205 is meshed with the surface of the gear 204. The gear ring 205 is rotatably connected to the inner cavity of the filter bucket 101 and the lower connecting ring 109. A positioning block 206 is fixedly connected to the inner cavity of the gear ring 205. There are two positioning blocks 206. An insert block 212 is movably connected to the bottom of the positioning block 206. A cleaning scraper 213 is fixedly connected to the bottom of the insert block 212. The cleaning scraper 213 is attached to the inner wall of the ash hopper 106.

[0027] Reference Figure 6 and Figure 7Telescopic rods 207 are movably connected to both sides of the inner cavity of the positioning block 206. A limit block 209 is fixedly connected to the other end of each telescopic rod 207. A tension spring 208 is sleeved on the surface of the telescopic rod 207. One end of the tension spring 208 is fixedly connected to the surface of the positioning block 206, and the other end is fixedly connected to one side of the limit block 209. A connecting rod 210 is fixedly connected to the surface of the limit block 209. A connector strip 211 is fixedly connected to one side of the connecting rod 210, and one end of the connector strip 211 is inserted into a connector. Inside block 212, the telescopic rod 207 guides the movement of the limiting block 209, preventing the limiting block 209 from moving out of its set position. The tension spring 208 deforms when the limiting block 209 moves and quickly recovers its deformation when the limiting block 209 is no longer under force, which in turn drives the insert strip 211 to engage with the inner cavity of the insert block 212. Finally, the limiting block 209 provides a fixing point for the tension spring 208, achieving the effect of fixing the tension spring 208.

[0028] Reference Figure 4 and Figure 5 A U-shaped fixing plate 202 is fixedly connected to the surface of the motor 203. One side of the U-shaped fixing plate 202 is fixedly connected to the surface of the filter barrel 101. A dust cover 201 is fixedly connected to the surface of the U-shaped fixing plate 202. One side of the dust cover 201 is fixedly connected to one side of the filter barrel 101, the lower connecting ring 109, and the connecting ring 6. The U-shaped fixing plate 202 is fixed to prevent the motor 203 from detaching from the surface of the filter barrel 101. The dust cover 201 also prevents unfiltered dust from leaking into the external environment through the interface between the gear 204 and the gear ring 205.

[0029] Reference Figure 5 and Figure 6 The guide mechanism 3 includes a square block 301 and a slide groove 305. The slide groove 305 is opened in the inner cavity of the filter barrel 101. The square block 301 is fixedly connected to the top of the gear ring 205. There are several square blocks 301. A concave block 302 is fixedly connected to the top of the square block 301. A guide wheel 304 is rotatably connected to the inner cavity of the concave block 302. The surface of the guide wheel 304 is slidably connected to the inside of the slide groove 305. The guide wheel 304 provides support for the gear ring 205, thereby preventing the gear ring 205 from falling off when rotating. The slide groove 305 also guides the movement of the gear ring 205, so that the gear ring 205 can rotate stably within the set trajectory.

[0030] Reference Figure 6A rotating shaft 303 is fixedly connected to the inner cavity of the recess 302. The surface of the rotating shaft 303 is rotatably connected to the inner cavity of the guide wheel 304. The rotating shaft 303 supports the guide wheel 304 and prevents the guide wheel 304 from falling out of the interior of the recess 302 when rotating, thereby affecting the normal operation of the gear ring 205.

[0031] Reference Figure 1 and Figure 2 A flange 4 is fixedly connected to the bottom of the lower connecting ring 109. A mounting plate 5 is fixedly connected to the bottom of the flange 4 by bolts. A leg bracket 105 is fixedly connected to the bottom of the mounting plate 5. There are three leg brackets 105. The bottom of the mounting plate 5 is fixedly connected to the top of the ash hopper 106. Through the cooperation of the flange 4 and the mounting plate 5, when the cleaning scraper 213 is damaged, the bolts can be turned to separate the lower connecting ring 109 and the ash hopper 106, so that maintenance personnel can easily replace the cleaning scraper 213.

[0032] Reference Figure 2 A circular support plate 107 is fixedly connected to the inner cavity of the filter barrel 101, and a filter bag 108 is fixedly connected to the inner cavity of the circular support plate 107. There are several filter bags 108. The circular support plate 107 supports the position of the filter bags 108 to prevent them from falling off. The filter bags 108 also efficiently filter the exhaust gas drawn into the filter barrel 101.

[0033] Working Principle: During operation, exhaust gas first enters the filter bucket 101 through the inlet pipe 104. Larger particles in the exhaust gas fall directly into the ash hopper 106, while smaller particles adhere to the surface of the filter bag 108. When a certain amount of particles adhere, a pulsed airflow is activated to remove these particles. When the humidity in the exhaust gas is high, dust adheres to the inner wall of the ash hopper 106. Then, the motor 203 is activated, rotating the gear ring 205. This rotation, in turn, rotates the positioning block 206, which in turn rotates the insertion block 212 and the cleaning scraper 213, thus cleaning the inner wall of the ash hopper 106. Accumulated dust is scraped off and discharged from the filter bucket 101 through the outlet. When the cleaning scraper 213 has been used for too long and needs to be replaced, the mounting plate 5 and flange 4 are separated by turning the bolts. Then, the maintenance personnel pull the connecting rod 210, which moves the limit block 209. The movement of the limit block 209 causes the tension spring 208 to deform, and the movement of the connecting rod 210 causes the insertion strip 211 to disengage from the inside of the insertion block 212. At this time, the motor 203 and the insertion block 212 can be removed and replaced. After the cleaning scraper 213 is replaced, the connecting rod 210 is released, the tension spring 208 returns to its original deformation, and then the insertion strip 211 is quickly inserted into the inside of the cleaning scraper 213. The replacement is then complete.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
