Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, specifically a bag filter exhaust gas purification device. Background Technology

[0002] Baghouse dust collection is a highly efficient dry dust collection technology that uses fiber fabric filter bags to capture solid particles in dust-laden gas. When the dusty airflow enters the dust collector, the particles are trapped on the outer surface of the filter bags through inertial collision, sieving, and interception, while clean gas passes through the filter material and is discharged.

[0003] For example, authorization announcement number CN107158826B discloses a bag filter dust collector, relating to the field of environmental protection device design technology. This invention mainly utilizes the buffering effect of baffles with baffle blades to reduce the impact of dust-laden gas entering the bag filter on the filter bags. During backflushing, the backflushing gas drives the spiral blades installed in the filter bags to rotate, generating centrifugal force to efficiently remove dust accumulated at all angles of the filter bags. Furthermore, thanks to the interception effect of the baffle blades, most coarse particles can fall directly into the ash hopper, preventing excessive coarse particles from adsorbing onto the filter bag surface and affecting the backflushing effect. In use, multiple backflushing cycles are unnecessary to allow dust accumulated on the filter bag surface to fall into the ash hopper, saving energy and effectively solving the problems of traditional bag filters where dust-laden gas directly washes over the filter bags and the backflushing efficiency is low.

[0004] However, the dust collectors in the above technologies do not have a cleaning mechanism inside the dust hopper, and the filtered dust tends to accumulate on the inner wall of the dust hopper after falling, making it difficult to clean. Therefore, there is an urgent need in the market to develop a bag filter dust collector for purifying exhaust gas to help people solve the existing problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4This utility model provides an embodiment of a baghouse dust collector exhaust gas purification device, comprising a filter tank 1, a partition plate 2 fixedly connected to the lower end of the filter tank 1, an annular support plate 103 fixedly connected to the upper end of the filter tank 1, a vibrating plate 106 connected to the upper end of the annular support plate 103, a plurality of dust collector bags 202 connected in an annular array between the partition plate 2 and the vibrating plate 106, a dust hopper 3 fixedly connected to the lower end of the filter tank 1, a support pipe 4 fixedly connected to the middle of the partition plate 2, a drive shaft 5 rotatably connected inside the support pipe 4, the lower end of the drive shaft 5 extending into the dust hopper 3 and having oblique brush rods 501 fixedly connected to both sides, a dust-laden gas inlet pipe 101 fixedly connected to the lower end of one side of the filter tank 1, and a clean gas outlet pipe 102 fixedly connected to the upper end of the other side of the filter tank 1. Multiple air vents 201 are arranged in a ring array on the partition plate 2. The lower ends of multiple dust collector bags 202 are fixedly connected to the upper ends of the multiple air vents 201 respectively. Each dust collector bag 202 is fixedly connected to the upper end of the upper end of the multiple air vents 201. The upper end of each connector 203 is connected to the lower end face of the vibrating plate 106 through a second spring 204. The dust-laden gas enters the lower end of the partition plate 2 inside the filter tank 1 through the dust-laden gas inlet pipe 101, and enters the dust collector bag 202 through the multiple air vents 201 for filtration. The filtered clean gas is discharged through the clean gas outlet pipe 102. The dust filtered on the inner wall of the dust collector bag 202 falls into the ash hopper 3. The rotation of the drive shaft 5 drives the two inclined brush rods 501 to rotate synchronously to clean the inner wall of the ash hopper 3, preventing dust from accumulating on the inner wall of the ash hopper 3.

[0020] Please see Figure 2 and Figure 4A ring-shaped support plate 103 has multiple guide posts 104 fixedly connected in a ring array on its upper end face. The upper ends of the multiple guide posts 104 all pass through the vibrating plate 106 and extend beyond the upper end face of the vibrating plate 106. A first spring 105 is sleeved between the ring-shaped support plate 103 and the vibrating plate 106 and on each guide post 104. The vibrating plate 106 is supported by the multiple first springs 105, and the vibrating plate 106 is guided to rise and fall by the multiple guide posts 104. A guide tube 107 is fixedly connected to the middle of the vibrating plate 106. The upper end of the support tube 4 passes through the middle of the guide tube 107 and is fixedly connected to the upper end face of the inside of the filter tank 1. A transmission box 401 is fixedly connected to the support tube 4 and the upper end of the vibrating plate 106. The upper end of the transmission shaft 5 extends into the transmission box 401 and is fixedly connected to a first bevel gear 502. Eccentric blocks 6 are provided on both sides of the transmission box 401. Rotating shafts 601 are fixedly connected to the inner side of each eccentric block 6. The ends of the two rotating shafts 601 away from the eccentric blocks 6 extend into the transmission box 401 and are fixedly connected to the second bevel gears 602. The two second bevel gears 602 are meshed with the teeth of the first bevel gear 502. The transmission shaft 5 drives the inclined brush rod 501 to rotate while simultaneously driving the two rotating shafts 601 to rotate. This causes the two rotating shafts 601 to drive the two eccentric blocks 6 to rotate synchronously. As the eccentric blocks 6 rotate, they intermittently press down on the vibrating plate 106, causing the vibrating plate 106 to vibrate up and down. This vibration is caused by the second spring 204 to drive the dust collector bag 202 to vibrate, causing the dust attached to the inner wall of the dust collector bag 202 to fall into the ash hopper 3 under the action of vibration.

[0021] Please see Figure 2 and Figure 3 A drive device 7 is fixedly connected to the middle of the upper end face of the filter tank 1. A drive motor 701 is fixedly installed inside the drive device 7. The upper end of the transmission shaft 5 extends into the drive device 7 and is connected to the output shaft of the drive motor 701 through a reducer. The drive motor 701 drives the transmission shaft 5 to rotate slowly.

[0022] Please see Figure 2 The lower end of the ash hopper 3 is fixedly connected to the ash discharge pipe 301, the lower end of the ash discharge pipe 301 is fixedly connected to the connecting plate 302, and the lower end of the connecting plate 302 is fixedly connected to the ash collection box 303 by bolts 304. The dust inside the ash hopper 3 enters the ash collection box 303 through the ash discharge pipe 301 for collection.

[0023] Working Principle: During operation, dust-laden gas enters the chamber below the partition plate 2 inside the filter tank 1 through the dust-laden gas inlet pipe 101. Under negative pressure, the dust-laden gas enters the dust collector bag 202 through the vent 201 on the partition plate 2. Dust particles are trapped on the inner surface of the dust collector bag 202, and the purified gas is discharged through the clean gas outlet pipe 102. The drive motor 701 drives the transmission shaft 5 to rotate through the reducer. On the one hand, it drives the inclined brush rod 501 to continuously clean the inner wall of the ash hopper 3 to prevent dust accumulation; on the other hand, it drives the two second bevel gears 602 to rotate synchronously through the first bevel gear 502, causing the eccentric block 6 to rotate periodically. During the rotation, the eccentric block 6 intermittently presses down on the vibrating plate 106. With the reset action of the first spring 105, the vibrating plate 106 vibrates up and down, which in turn drives all the dust collector bags 202 to shake synchronously through the second spring 204, shaking the dust attached to the inner wall of the filter bags into the ash hopper 3. The collected dust eventually falls into the dust collection box 303 through the dust discharge pipe 301, and the dust collection box 303 can be cleaned periodically by removing the bolts 304.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
