Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a pulse bag type dust collector. Background Art

[0002] When the pulse bag dust collector is working normally, the dust-containing gas enters the ash hopper from the air inlet. Due to the rapid expansion of the gas volume, some coarser dust particles fall into the ash hopper due to inertia or natural sedimentation, and most of the remaining dust particles rise with the air flow and enter the bag chamber. After being filtered by the filter bag, the dust particles are retained on the outside of the filter bag. The purified gas goes to the clean air chamber and is discharged into the atmosphere by the fan, thereby achieving the purpose of dust removal.

[0003] An existing pulse bag dust collector (publication number: CN218853741U) has at least the following disadvantages: during the filtering process of the above device, dust falls into the ash hopper from the ash discharge hole. However, dust is easy to adhere to the inner wall of the ash discharge port during the ash discharge process. If too much dust accumulates, it is easy to cause the discharge efficiency of the ash discharge port to decrease, or even block the ash discharge port, affecting the cleaning work inside the dust collector, thereby affecting the dust removal effect of the dust collector. For this reason, we propose the utility model. Utility Model Content

[0023] Please see attached Figure 1 -Attached Figure 5 A pulse bag dust collector comprises an ash discharge hopper 2 connected and fixed to the bottom surface of a dust collector body 1, wherein a cleaning structure is arranged inside the ash discharge hopper 2, and the cleaning structure comprises a mounting plate 201 fixed inside the ash discharge hopper 2, a transmission rod 202 is rotatably arranged on the bottom surface of the mounting plate 201, a rotating disk 203 is fixed on the outer circular wall surface of the transmission rod 202, a plurality of tooth blocks 204 are fixed on the outer circular wall surface of the rotating disk 203, and the plurality of tooth blocks 204 are evenly distributed along the circumference of the rotating disk 203, and both sides of the plurality of tooth blocks 204 are inclined surfaces, a fixing plate 208 is fixed on both sides of the mounting plate 201, and two stabilizing plates 205 are fixed on the bottom surface of the mounting plate 201, and a mounting cylinder 206 is fixed on one side of the stabilizing plate 205 and the fixing plate 208, and a movable rod 207 is slidably inserted in the interior of the mounting cylinder 206, and the dust collector body 1 is a pulse bag dust collector.

[0024] In this embodiment, one end of the movable rod 207 is in contact with the inner wall of the ash hopper 2, and the other end of the movable rod 207 is in contact with the outer wall of the tooth block 204. A spring 3 is fixed between the movable rod 207 and the mounting tube 206. A fan blade 301 is fixed to the outer cylindrical wall of the transmission rod 202. The fan blade 301 is located below the rotating disk 203. A driving motor is fixed to the top surface of the mounting plate 201. The output end of the driving motor passes through the top surface of the mounting plate 201 and is fixed to the top of the driving rod 202. Through the setting of the cleaning structure, after the dust collector body 1 is unloaded, the staff starts the driving motor to drive the rotating disk 203 to rotate through the transmission rod 202. The other end of the rod 207 fits with the outer circumferential wall of the tooth block 204. When the rotating disk 203 rotates, the tooth block 204 continuously pushes the movable rod 207. The movable rod 207 reciprocates in the horizontal direction under the action of the spring 3, so that one end of the movable rod 207 pushes the inner wall of the ash hopper 2, thereby forming a small-amplitude and high-frequency vibration, and then vibrates the dust attached to the inner wall of the ash hopper 2 and drops it. At the same time, the transmission rod 202 drives the fan blades 301 to rotate when it rotates. The rotation of the fan blades 301 causes the airflow in the ash hopper 2 to move downward, accelerates the discharge of the shaken dust, improves the dust discharge efficiency, prevents the ash hopper 2 from being blocked, and ensures the cleanliness of the inside of the dust collector body 1.

[0025] In this embodiment, a limiting ring 4 is fixed on the outer circumferential wall of the movable rod 207, and one side of the limiting ring 4 abuts against one end of the mounting tube 206. When the movable rod 207 reciprocates under the action of the spring 3, the limiting ring 4 drives the movement of the movable rod 207 to limit the position when the spring 3 is reset, thereby preventing the movable rod 207 from causing a large impact on the tooth block 204 and improving the stability of the device.

[0026] In this embodiment, the end of the movable rod 207 close to the inner wall of the ash hopper 2 is a round head, and the end of the movable rod 207 close to the tooth block 204 is an arc surface. The frustum and arc surface design at both ends of the movable rod 207 cause damage to the inner wall of the ash hopper 2 when the movable rod 207 pushes the inner wall. At the same time, the arc surface end of the movable rod 207 can better adapt to the pushing of the tooth block 204.

[0027] In this embodiment, an ash discharge valve 5 is fixed inside the ash discharge hopper 2, and a filter bag 501 is fixed to the ash discharge hopper 2 through bolts. When discharging ash, the staff can open the ash discharge valve 5, and the fan blades 301 blow the dust into the filter bag 501 for collection.

[0028] In this embodiment, the inner wall of the ash discharge hopper 2 is inclined from the periphery to the center, and the inclination of the inner wall of the ash discharge hopper 2 can help the dust to be discharged.

[0029] Working principle: In use, after the dust collector body 1 is unloaded, the staff starts the driving motor to drive the rotating disk 203 to rotate through the transmission rod 202. Since the other end of the movable rod 207 is in contact with the outer circumferential wall of the tooth block 204, when the rotating disk 203 rotates, the tooth block 204 continuously pushes the movable rod 207. The movable rod 207 reciprocates in the horizontal direction under the action of the spring 3, so that one end of the movable rod 207 pushes the inner wall of the ash hopper 2, thereby forming a small-amplitude high-frequency vibration, and then the dust attached to the inner wall of the ash hopper 2 is vibrated and falls off. At the same time, the transmission rod 202 drives the fan blades 301 to rotate when it rotates, and the rotation of the fan blades 301 causes the air in the ash hopper 2 to flow to the The movable rod 207 moves downward to accelerate the discharge of the shaken-off dust. When the movable rod 207 reciprocates under the action of the spring 3, the limit ring 4 drives the movement of the movable rod 207 to limit the position when the spring 3 is reset, preventing the movable rod 207 from causing a large impact on the tooth block 204, thereby improving the stability of the device. The frustum and arc surface design at both ends of the movable rod 207 cause damage to the inner wall of the ash hopper 2 when the movable rod 207 pushes the inner wall thereof. At the same time, the arc surface end of the movable rod 207 can make it better adapt to the pushing of the tooth block 204. The staff can open the ash discharge valve 5 when discharging ash, and the fan blades 301 blow the dust into the filter bag 501 for collection. The inclination of the inner wall of the ash hopper 2 can help discharge the dust.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
