Description
Technical Field
[0001] The utility model relates to the technical field of dust removal and material collection devices, in particular to a plastic particle dust removal and material collection device. Background Art
[0002] Plastic particles are the common name for plastic particles. They are the raw materials for storage, transportation and processing of plastics in the form of semi-finished products. During the production of plastic particles, a large amount of dust will adhere to the surface of the plastic particles, which needs to be removed by a dust removal mechanism.
[0003] When using existing dust removal equipment, the raw materials are generally transported into the dust removal equipment, and then the dust is separated from the raw materials through vibration screening to complete the dust removal process. However, during dust removal, since the surface of plastic particles contains static electricity, the dust is adsorbed on the surface of the plastic particles under the action of static electricity, making it difficult to remove. In addition, during the dust removal process, since the dust particles are smaller in size and lighter in weight than plastic particles, the dust will float in the dust removal equipment during the vibration dust removal process, resulting in the dust not being fully removed and poor use effect. To this end, we propose a plastic particle dust collection device. Utility Model Content

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] Reference Figure 1-Figure 4A plastic particle dust removal and collection device includes a base 1, a control cabinet 33 is installed on the top of the base 1, a controller is installed in the control cabinet 33, the controller is a control mainboard, a host or a PLC logic controller, a shell 9 is installed on the top of the base 1 through a plurality of legs 8, a silo 17 is installed at one end of the top of the shell 9, a screw feeder 4 is provided on one side of the shell 9, and a discharge port of the screw feeder 4 is connected to the side of the silo 17. In actual use, the staff can transport the raw materials into the silo 17 through the screw feeder 4, and then the plastic particle raw materials can fall into the shell 9 through the silo 17 for dust removal.
[0029] like Figure 2 As shown, the top of the interior of the silo 17 is rotatably connected to a screw conveying shaft 19, the bottom of the screw conveying shaft 19 extends into the interior of the silo 17, the top of the screw conveying shaft 19 is connected to a second drive motor 18, the second drive motor 18 is fixed to the top of the silo 17, and the second drive motor 18 is connected to the controller through a wire. In actual use, the second drive motor 18 can drive the screw conveying shaft 19 to rotate, and the plastic particle raw materials falling into the silo 17 are transported to the outer shell 9, so that the raw materials fall evenly.
[0030] It should be noted that the edge of the spiral blade on the spiral conveying shaft 19 is in clearance with the inner wall of the silo 17 , so that during the feeding process, the plastic particles will not be adsorbed on the inner wall of the silo 17 under the action of static electricity, and will not block the bottom of the silo 17 .
[0031] like Figure 2 and Figure 3 As shown, a mounting groove 21 is provided at one end of the shell 9, and an ion fan 20 is provided inside the mounting groove 21. Both ends of the ion fan 20 are fixed on the shell 9. A second sieve plate 22 is provided inside the shell 9. The second sieve plate 22 is located below the ion fan 20, and one end of the second sieve plate 22 extends to below the silo 17. The ion fan 20 is connected to the controller through a wire. In actual use, the ion fan 20 can blow ion wind onto the falling plastic particle raw materials. In the process of the plastic particles falling on the second sieve plate 22, the ion wind can remove the static electricity on the plastic particles, so that dust will not be adsorbed on the plastic particles, which is convenient for subsequent dust removal.
[0032] like Figure 2 and Figure 4 As shown, a pair of fixing blocks 31 are symmetrically installed on both sides of the interior of the outer shell 9, and each pair of fixing blocks 31 are connected by a guide rod 30. A number of connecting blocks 28 are symmetrically installed on both sides of the second sieve plate 22, and each connecting block 28 is slidably sleeved on the guide rod 30. Under the action of the guide rod 30, the second sieve plate 22 can be limited so that the second sieve plate 22 remains stable.
[0033] like Figure 2 and Figure 4 As shown, two second rotating shafts 29 are coaxially connected to the inner sides of the shell 9, one end of which is equipped with a first driving motor 5, which is fixed on the side of the shell 9, and the first driving motor 5 is connected to the controller through a wire. The proximal ends of the two second rotating shafts 29 are vertically equipped with connecting shafts 24, and the ends of the two connecting shafts 24 are connected through a first rotating shaft 25. A connecting rod 26 is rotatably connected to the first rotating shaft 25, and the end of the connecting rod 26 is fixed to the bottom of the second sieve plate 22 through a hinge seat. In actual use, the first driving motor 5 can drive the connecting rod 26 to reciprocate under the action of the first rotating shaft 25, so as to control the reciprocating motion of the second sieve plate 22, and screen the plastic particles falling on the second sieve plate 22, and some dust will pass through the second sieve plate 22 and float to the bottom of the shell 9, thereby completing the separation of plastic particles and dust.
[0034] like Figure 1 and Figure 2 As shown, a discharge trough 27 is provided at one end of the shell 9, and a guide plate 11 is installed at the bottom of the discharge trough 27. The guide plate 11 is inclined, and one end of the guide plate 11 extends to the bottom of the second sieve plate 22, and the other end of the guide plate 11 extends to the outside of the discharge trough 27. A collection barrel 10 is provided below the discharge trough 27, and the collection barrel 10 is installed on the base 1. The plastic particles falling on the second sieve plate 22 can flow along the second sieve plate 22 to the guide plate 11, and finally fall into the collection barrel 10 through the guide plate 11 for collection.
[0035] It should be noted that the second sieve plate 22 is arranged to be inclined downward, so that the plastic particles can move along the second sieve plate 22 under the action of gravity, and finally fall onto the guide plate 11, and then fall into the collection barrel 10 along the guide plate 11 for collection.
[0036] like Figure 4 As shown, strip baffles 32 are installed on both sides of the second sieve plate 22, and the first sieve plate 14 is installed at one end of the top of the two strip baffles 32. An opening is formed between the first sieve plate 14 and the two strip baffles 32, and the opening is located below the silo 17. During actual use, some dust will pass through the first sieve plate 14 and drift to the upper end of the inner part of the outer shell 9, so that the dust and plastic particles can be more fully separated.
[0037] like Figure 1 and Figure 3As shown, a top cover 16 is installed on the top of the shell 9, and an ash collecting pipe 13 is provided on one side of the shell 9. The two ends of the ash collecting pipe 13 are respectively fixed on the top of the top cover 16 and the bottom of the shell 9. An adsorption pipe 7 is installed on the side of the ash collecting pipe 13. The end of the adsorption pipe 7 is fixed on the air inlet end of the suction pump 2, and the suction pump 2 is fixed on the base 1. The suction pump 2 is connected to the controller through a wire. An exhaust pipe 6 is installed on the air outlet end of the suction pump 2. The end of the exhaust pipe 6 is fixed on the top of the filter barrel 3, and the filter barrel 3 is fixed on the base 1. In actual use, the suction pump 2 can suck out the air in the shell 9 through the adsorption pipe 7 and the ash collecting pipe 13, so that the dust floating at the upper and lower ends of the shell 9 will be transported to the exhaust pipe 6 through the ash collecting pipe 13 and the adsorption pipe 7, and finally transported to the filter barrel 3, the dust is filtered out by the filter barrel 3, and the clean air passes through the filter barrel 3 and is discharged into the external environment.
[0038] Specifically, when the utility model is in use, the staff transports the plastic particle raw material to the silo 17 through the screw feeder 4, and then controls the second drive motor 18 to work through the controller. The second drive motor 18 drives the screw conveying shaft 19 to rotate, and the plastic particle raw material in the silo 17 is evenly transported to the shell 9. At the same time, the controller controls the ion fan 20 and the first drive motor 5 to work. The ion fan 20 blows the ion wind to the plastic particle raw material falling into the shell 9. When the plastic particle raw material falls on the second sieve plate 22, the static electricity will be removed by the ion wind, and the dust cannot adhere to the surface of the plastic particle raw material under the action of static electricity. The first drive motor 5 drives the second sieve plate 22 to reciprocate to filter the dust on the plastic particle raw material. Part of the dust passes through the second sieve plate 22 and floats to the bottom of the outer shell 9. At the same time, the plastic particle raw material will move along the second sieve plate 22. While moving, part of the dust will pass through the first sieve plate 14 and float to the upper part of the inner part of the outer shell 9. At the same time, the staff controls the suction pump 2 to work through the controller. The dust in the outer shell 9 of the suction pump 2 is sucked into the exhaust pipe 6 through the ash collecting pipe 13 and the adsorption pipe 7, and finally the dust is transported to the filter screen barrel 3. The dust is blocked by the side wall of the filter screen barrel 3. The clean air in the filter screen barrel 3 will pass through the side wall of the filter screen barrel 3 and be discharged into the external environment, completing the dust removal treatment of the plastic particle raw material. The plastic particle raw material after dust removal will fall into the guide plate 11 along the second sieve plate 22, and finally fall into the collecting barrel 10 for collection.
[0039] Furthermore, if Figure 1 As shown, baffle plates 12 are vertically installed on both sides of the top of the guide plate 11. The baffle plates 12 can block both sides of the guide plate 11, so that the plastic particle raw materials will not scatter from both sides of the guide plate 11 during the flow on the guide plate 11.
[0040] Furthermore, if Figure 4As shown, a strip guide plate 23 is installed at one end of the top of the strip baffle 32, and the top of the strip guide plate 23 is inclined. The top edge of the strip guide plate 23 is gap-matched with the inner wall of the shell 9, and one end of the strip guide plate 23 is fixed to the end of the first sieve plate 14. Under the action of the strip guide plate 23, the plastic particle raw materials falling from the silo 17 can be guided so that all the plastic particle raw materials fall on the second sieve plate 22 for dust removal.
[0041] Furthermore, if Figure 2 and Figure 4 As shown, a filter cloth 15 is installed at one end of the top of the first sieve plate 14, the top of the filter cloth 15 is fixed to the top of the shell 9, and the two sides of the filter cloth 15 are fixed to the ends of the strip drainage plate 23. When removing static electricity on the plastic particle raw material, the filter cloth 15 can block the plastic particle raw material to prevent the plastic particle raw material from being blown to the top of the first sieve plate 14 by the ion wind, so as not to affect the subsequent dust removal treatment, and the ion wind will blow part of the dust adhering to the surface of the plastic particle raw material away from the surface of the plastic particle raw material, and the dust will pass through the filter cloth 15 and be adsorbed by the ash collecting pipe 13.
[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
