Description

Technical Field

[0001] The utility model relates to the field of paste resin production machinery, in particular to a paste resin packaging dust collector. Background Art

[0002] As the name implies, polyvinyl chloride (PVC) paste resin is mainly used in the form of paste. People often use this paste as plasticized paste, which is a unique liquid form of unprocessed polyvinyl chloride plastic. Paste resin is often made by emulsion and microsuspension method.

[0003] At present, in the processing and packaging of paste resin, especially involving dust removal operations in space environments, the existing dust removal equipment only sucks the dust through the suction pipe, filters the material dust through the filter bag, and then discharges the filtered gas through the exhaust port. However, the dust adhered to the surface of the filter bag cannot be cleaned automatically, which easily leads to clogging of the filter bag. Manual cleaning is time-consuming, laborious and inefficient, which in turn affects the efficiency of the dust removal operation. Utility Model Content

[0004] The utility model aims to provide a paste resin packaged dust collector to solve the problem that the dust adhered to the surface of the filter bag in the existing dust removal equipment cannot be automatically cleaned, which easily leads to clogging of the filter bag and further affects the efficiency of the dust removal operation.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A paste resin packaging dust collector comprises a dust removal box, wherein a filter chamber and a sedimentation chamber are sequentially arranged inside the dust removal box from top to bottom, the filter chamber is connected with the sedimentation chamber through a through hole, a filter bag with an opening facing the filter chamber is arranged in the through hole, two sliding bars are vertically fixed in the filter chamber, the two sliding bars are slidably connected with the same cross bar, support springs are sleeved on the outer sides of the two sliding bars, and the two ends of the support springs are respectively connected with the bottom side of the filter chamber and the bottom side of the cross bar; two magnets are arranged on the inner wall of the top of the filter chamber, a magnetic block that is magnetically attracted to each other is arranged on the top of the cross bar, and a knocking rod movably placed inside the filter bag is arranged on the bottom side of the cross bar; a suction fan connected with the inside of the filter chamber through an exhaust channel is arranged on the outer side of the top of the dust removal box, and a dust suction channel connected with the inside of the sedimentation chamber is arranged at the bottom end of the sedimentation dust removal box.

[0007] A further technical solution is that a plurality of support rings are fixedly connected to the inner side of the filter bag, a rubber block is fixedly provided on the bottom side of the inner part of the filter bag, and a hemispherical block is provided at the bottom end of the knocking rod.

[0008] A further technical solution is to provide a plurality of through holes, wherein filter bags are fixedly connected to the plurality of through holes respectively; and the knocking rod arranged at the bottom side of the cross bar matches the number of the filter bags.

[0009] A further technical solution is that an annular spray pipe is provided above the dust suction channel in the sedimentation chamber, and a plurality of spray heads are provided on the annular spray pipe; a water inlet pipe connected to the annular spray pipe is provided on the outside of the dust removal box, and a collecting tank connected to the inside of the sedimentation chamber is provided on the bottom side of the dust removal box.

[0010] A further technical solution is that the aggregate tank is detachably connected to the bottom side of the dust removal box through a conical aggregate barrel, the top of the aggregate barrel is connected to the dust removal box, a raised locking block is provided on the bottom outer wall of the aggregate barrel, and an L-shaped buckle groove matching the locking block is provided on the top inner wall of the aggregate tank.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Example:

[0020] refer to Figures 1 to 4The figure shows a paste resin packaging dust collector, comprising a dust box 1, a supporting leg is installed at the bottom of the dust box 1, and a filter chamber 2 and a sedimentation chamber 3 are arranged in the interior of the dust box 1 from top to bottom, the filter chamber 2 is connected with the sedimentation chamber 3 through a through hole, a filter bag 4 with an opening facing the filter chamber 2 is arranged in the through hole, two sliding rods 5 are vertically fixed in the filter chamber 2, the two sliding rods 5 are slidably connected with the same cross bar 6, and sliding holes matching the sliding direction of the sliding rod 5 are respectively opened at both ends of the cross bar 6, and the two ends of the cross bar 6 are respectively slidably sleeved on the outside of the two sliding rods 5 through the sliding holes, and the outsides of the two sliding rods 5 are sleeved with supporting springs 7, and the two ends of the supporting spring 7 are respectively connected to the bottom side of the filter chamber 2 and the bottom side of the cross bar 6; two magnets 8 are arranged on the inner wall at the top of the filter chamber 2, and the top of the cross bar 6 A magnetic block 9 is provided which is magnetically attracted to the magnets 8, and a knocking rod 10 which is movably placed inside the filter bag 4 is provided on the bottom side of the cross bar 6; a suction fan 12 which is connected to the inside of the filter chamber 2 through an exhaust channel 11 is provided on the outside of the top of the dust removal box 1, and a dust suction channel 13 which is connected to the inside of the sedimentation chamber 3 is provided at the bottom end of the dust removal box 1. In actual use, when the device is used for filtering, the port of the dust suction channel 13 is placed in a suitable position for packaging work, and the suction fan 12 is started to work. The gas containing dust enters the sedimentation chamber 3 through the dust suction channel 13, is filtered by the filter bag 4, and the filtered gas enters the filter chamber 2, and is discharged through the exhaust channel 11 and the exhaust port 26 of the suction fan 12. When the suction fan 12 is working, the gas inside the sedimentation chamber 3 passes through the dust suction channel 13. The flow inside the filter chamber 2 and the air flow exert a thrust on the cross bar 6. Under the action of the supporting force of the supporting spring 7 and the adsorption force of the magnetic block 9 and the magnet 8, the thrust causes the magnetic block 9 and the magnet 8 on the cross bar 6 to adsorb to each other. However, as the dust adsorbed on the surface of the filter bag 4 accumulates more and more, the air inside the sedimentation chamber 3 passes through the filter bag 4 less and less, making the thrust of the flowing air smaller and smaller. When the thrust generated by the air flow drops to a specified level, the sum of the supporting force of the supporting spring 7, the adsorption force of the magnetic block 9 and the magnet 8 and the thrust of the air flow is less than the sum of the gravity of the cross bar 6 and the knocking rod 10. Under the action of the gravity of the cross bar 6 and the knocking rod 10, the magnetic block 9 breaks free from the adsorption of the magnet 8. At this time, under the gravity of the cross bar 6 and the knocking rod 10, the cross bar 6 slides down, and the knocking rod 10 knocks the bottom of the filter bag 4, causing the filter bag 4 to vibrate, and then the dust adsorbed on the lower surface of the filter bag 4 can be shaken off to settle in the sedimentation chamber 3. Since the spring has a maximum elastic pressure, the cross bar 6 and the knocking rod 10 move back and forth up and down, so that the knocking rod 10 knocks the filter bag 4 back and forth. When the dust in the filter bag 4 is cleaned, the gas inside the sedimentation chamber 3 is driven to flow into the filter chamber 2 under the suction work of the suction fan 12, so that the air thrust is restored. Under the thrust generated by the air flow, the magnetic block 9 and the magnet 8 are adsorbed on each other, and then when the angle of the dust adhering to the filter bag 4 affects the filtering effect of the filter bag 4, the dust on the lower surface of the filter bag 4 can be automatically cleaned to ensure high filtering efficiency.

[0021] refer to Figure 1 , Figure 2 As shown, a plurality of support rings 14 are fixedly connected to the inner side of the filter bag 4, a rubber block 15 is fixedly provided on the bottom side of the inner part of the filter bag 4, and a hemispherical block 16 is provided at the bottom end of the knocking rod 10. The support ring 14 can support the filter bag 4 to prevent the filter bag 4 from sticking to the outer wall of the knocking rod 10. The hemispherical block 16 provided at the bottom end of the knocking rod 10 can knock the rubber block 15 fixedly provided on the bottom side of the inner part of the filter bag 4, thereby causing the filter bag 4 to vibrate, thereby preventing the bottom end of the knocking rod 10 from directly contacting the filter bag 4, thereby damaging the filter bag 4 and affecting the subsequent filtering effect.

[0022] refer to Figure 1 As shown, there are multiple through holes, and filter bags 4 are fixedly connected to the multiple through holes respectively; the knocking rod 10 arranged on the bottom side of the cross bar 6 matches the number of filter bags 4. By setting multiple through holes, filter bags 4 and knocking rods 10, the high efficiency of filtration can be guaranteed.

[0023] refer to Figure 1 , Figure 3 As shown, an annular spray pipe 17 is provided above the dust suction channel 13 in the sedimentation chamber 3, and a plurality of spray heads 18 are provided on the annular spray pipe 17; a water inlet pipe 19 connected to the annular spray pipe 17 is provided on the outside of the dust removal box 1, and a collecting tank 20 connected to the inside of the sedimentation chamber 3 is provided on the bottom of the dust removal box 1. In actual use, the suction fan 12 sucks the dust-containing gas in the space through the dust suction channel 13, the annular spray pipe 17 is connected to the water circuit by the water inlet pipe 19, and the spray heads 18 on the annular spray pipe 17 are connected to the water circuit by the water inlet pipe 19. 8 sprays water mist toward the bottom side of the sedimentation chamber 3, so that most of the dust in the dust-containing gas sucked by the dust collection pipe is dissolved in the water mist and slowly falls through the sedimentation chamber 3 due to its own gravity and finally falls into the collecting tank 20. The dust that has not merged with the water mist is then filtered by the filter bag 4. At the same time, the dust in the dust-containing gas is first merged with the water mist sprayed by the spray head 18 on the annular spray pipe 17, which can reduce the amount of dust filtered by the filter bag 4, making it less likely to cause blockage of the filter bag 4 and improve the filtering effect.

[0024] refer to Figure 1 , Figure 4 As shown, the aggregate tank 20 is detachably connected to the bottom side of the dust removal box 1 through a conical aggregate barrel 21, and the top of the aggregate barrel 21 is connected to the dust removal box 1. A raised locking block 22 is provided on the bottom outer wall of the aggregate barrel 21, and an L-shaped buckle groove 23 matching the locking block 22 is provided on the top inner wall of the aggregate tank 20. When the aggregate tank 20 is installed at the lower part of the aggregate barrel 21, the locking block 22 is embedded in the buckle groove 23. By setting the locking block 22 and the buckle groove 23, when it is necessary to recycle the dust in the aggregate tank 20 and clean the aggregate tank 20, it is only necessary to rotate the aggregate tank 20 relative to the aggregate barrel 21 to easily achieve the buckling and disassembly of the aggregate tank 20, which is easy to operate, simple and practical.

[0025] refer to Figure 1 It is shown that the end of the dust suction channel 13 away from the dust removal box 1 is connected to a suction hood 24, and a filter 25 is provided at the hood opening of the suction hood 24. By setting the suction hood 24, the efficiency of dust suction gas can be improved, and the filter 25 can prevent lighter objects such as plastic bags from being sucked into the dust removal box 1, affecting the subsequent filtering effect.
