The air inlet 102 is connected to the feeding bin produced by PE plastic pipes through a pipeline, and the exhaust port 101 is connected to the fan, and the dust-containing waste gas in the material is extracted into the dust removal bin 1 by the negative pressure of the fan. A plurality of slots 201 are provided on the vibration suspension frame 2, and a vibration motor 202 is provided at the bottom of the vibration suspension frame 2, and the vibration of the vibration suspension frame 2 is formed by the vibration motor 202. The filter element 3 is inserted into the slot 201 one by one, and penetrates to the bottom of the vibration suspension frame 2. The filter element 3 is cylindrical, and its filtering part is located below the vibration suspension frame 2. The outside of the filter element 3 is filtered, and the filtered air is inflated and circulated upward inside, and the dust is filtered through the filter element 3. The suspension structure 4 is arranged between the vibration suspension frame 2 and the dust removal bin 1, and includes a ring plate 41, an elastic member 42 and a flexible sealing belt 43. The two ring plates 41 are arranged on the inner wall of the dust removal bin 1, and are distributed up and down, and are respectively arranged above and below the vibration suspension frame 2, so that the vibration suspension frame 2 is clamped between the two ring plates 41. The elastic member 42 is arranged between the ring plate 41 and the vibration suspension frame 2. The number of elastic members 42 is multiple, and they are evenly arranged at the top and bottom of the vibration suspension frame 2 for elastic support, providing suspension support for the vibration suspension frame 2, and providing elastic support for the vibration suspension frame 2 under vibration. The flexible sealing belt 43 is arranged between the vibration suspension frame 2 and the ring plate 41 for sealing the gap, sealing the gaps above and below the ring plate 41 and the vibration suspension frame 2, and the flexible sealing belt 43 can provide vibration for the vibration suspension frame 2.

[0036] It can be understood that the filter element 3 is installed through the vibration suspension frame 2, and the vibration power is provided by the vibration motor 202, so that the vibration suspension frame 2 is vibrated in the suspension structure 4, thereby having the effect of shaking off the dust attached to the filter element 3 during dust removal, reducing dust adhesion and reducing the probability of clogging.

[0037] In this embodiment, in order to facilitate the disassembly and assembly of the filter element 3, the dust removal bin 1 includes a bin body 11 and a cover plate 12. The cover plate 12 is detachably arranged on the top of the bin body 11. The cover plate 12 can be connected to the bin body 11 through a threaded structure or through bolts. The exhaust port 101 is opened on the cover plate, and the air inlet 102 and the slag discharge port 103 are both arranged on the bin body 11.

[0038] It can be understood that the filter element 3 in the bin body 11 can be installed and removed by removing the cover plate 12 .

[0039] In this embodiment, in order to limit the filter element 3 during insertion, the top end of the filter element 3 extends outward to form a limiting edge 301, and the limiting edge 301 is embedded in the slot 201. The slot 201 is a stepped groove with a step inside. The step is used to abut against the bottom of the limiting edge 301 to support the filter element 3 and limit the insertion of the filter element 3.

[0040] Furthermore, in order to quickly lift multiple filter elements 3, frame grooves 203 are opened between the slots 201. The frame grooves 203 are arranged on the vibration suspension frame 2 and pass through each slot 201. The lifting frame 207 is sleeved between the outer sides of several filter elements 3 and abuts against the bottom of the limiting edge 301. The lifting frame 207 is inserted between the inner sides of all the frame grooves 203. The lifting frame 207 is composed of annular frames and connecting frames corresponding to the number of filter elements 3. The annular frames are sleeved on the filter elements 3, and the connecting frames are arranged between multiple annular frames for connecting each annular frame and grabbing during lifting.

The inner side of the threaded ring 204 is threadedly connected with a positioning ring 206, which abuts against the top of the sealing pressure plate 205 for locking.

[0042] During installation, first insert the lifting frame 207 into the frame groove 203, and then insert the filter element 3 into the slot 201. After inserting the filter element 3, insert the sealing pressure plate 205 into the threaded ring 204 and press it to the top surface of the vibration suspension frame 2 and the top surface of the filter element 3. Then, thread the positioning ring 206 on the inner side of the threaded ring 204 and press it downward to the top of the sealing pressure plate 205. Press the sealing pressure plate 205 to the top surface of the vibration suspension frame 2 and the top surface of the filter element 3 to form a seal and lock.

[0043] In this embodiment, the elastic member 42 is a spring, and the flexible sealing belt 43 is a rubber belt. The rubber belt is flexible and has a certain elastic deformation ability. It can bend and stretch under the vibration of the vibration suspension frame 2 to provide gap sealing under vibration conditions.

[0044] It is understandable that the elastic member 42 may also be a rubber pad or a silicone pad or other elastic cushion layer to support the vibration suspension frame 2 and allow it to vibrate.

The back-blowing pipe 53 is arranged on the inner top wall of the cover plate, and a plurality of nozzles are opened at the bottom of the back-blowing pipe 53. The nozzles correspond to the top of the filter element 3 one by one. By starting the electromagnetic pulse valve 52, the gas in the gas tank 51 is introduced into the back-blowing pipe 53, and the air is back-blown into the filter element 3 from top to bottom, so that the attached dust is blown outward until it falls off, thereby achieving a cleaning effect.

[0046] Wherein, valves 104 are provided on the slag discharge port 103 and the air inlet 102 .

[0047] It can be understood that during dust removal, the valve 104 of the air inlet 102 is opened and the valve of the slag discharge port 103 is closed, and during cleaning, the valve 104 of the air inlet 102 is closed and the valve of the slag discharge port 103 is opened.

[0048] In this embodiment, in order to improve the stability of the filter element 3 during vibration, a reinforcement frame 6 is provided at the bottom of the vibration suspension frame 2, and the reinforcement frame 6 is sleeved on the bottom of the filter element 3 to improve the stability of the filter element 3 during vibration.

[0049] Specifically, the reinforcement frame 6 includes a connecting rod 61, an outer fixing ring 62 and a sleeve ring 63. The connecting rod 61 is arranged between the outer fixing ring 62 and the vibration suspension frame 2. The number of connecting rods 61 is several and distributed in a circular pattern. The sleeve ring 63 is arranged on the inner side of the outer fixing ring 62 in a one-to-one correspondence with the filter element 3. The sleeve ring 63 is used to provide structural reinforcement between the outer fixing ring 62.

[0050] The specific working process of the utility model is as follows: under the guidance of the fan, the air containing dust in the feed bin enters the dust removal bin 1 from the air inlet 102, and is discharged from the exhaust port 101 after being filtered by the filter element 3; during filtering, the vibration motor 202 is started to drive the vibration suspension frame 2 to vibrate, so that the filter element 3 on it vibrates synchronously, forming a shaking-off effect on the attached dust; when the filter element 3 is blocked, the valve 104 of the air inlet 102 is closed, and the valve of the slag discharge port 103 is opened, and the gas in the gas tank 51 is introduced into the backblowing pipe 53 by starting the electromagnetic pulse valve 52, and sprayed out from the nozzle to form a backblowing on the filter element 3 for cleaning; during disassembly and assembly, the cover plate 12 is first removed, and then the positioning ring 206 is rotated to remove, and then the sealing pressure plate 205 is pulled out, and finally the pulling frame 207 is extracted, so that multiple filter elements 3 can be pulled out from the vibration suspension frame 2 together, and the installation can be carried out in reverse according to the above principle.

[0051] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
