Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling and cleaning, in particular to a waste plastic recycling and cleaning pretreatment device. Background Art

[0002] Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. Waste plastic is a popular term and does not refer to waste, old and useless plastic products. In the process of processing waste plastics, they can be recycled and reshaped so that they can be put into daily use again.

[0003] When recycling waste plastics, since the recycled waste plastics are not clean, they need to be cleaned to remove the dirt attached to the plastics, and then crushed and reshaped for reshaping.

[0004] However, the existing cleaning method is mostly to put the plastic into a bucket and then rinse it with water, which makes it difficult to rinse off the dirt on the surface of the plastic, resulting in poor quality of subsequent reshaped plastic products. In addition, a large amount of water will remain in the cleaned plastic, which will affect the subsequent remolding process.

[0005] To this end, the inventors have designed and developed a waste plastic recycling, cleaning and pretreatment device. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] Reference Figure 1-7A waste plastic recycling cleaning pretreatment device comprises a cleaning box 1, a bracket 102 is provided at the bottom of the cleaning box 1, a sewage pipe 101 is connected to the bottom of the cleaning box 1, a cleaning cylinder 2 is provided in the cleaning box 1, a stabilizing plate 3 is provided at the bottom of the cleaning cylinder 2, a through hole 31 is provided at the bottom of the stabilizing plate 3, an adjusting mechanism 4 spliced ​​with the through hole 31 is provided at the bottom of the stabilizing plate 3, and a hole is provided at the bottom of the cleaning box 1 for the adjusting mechanism 4 to pass through;

[0032] A lower gear ring 103 is provided in the cleaning box 1, a filter plate 21 is provided on the cleaning cylinder 2, a rotating shaft 5 is provided on the cleaning cylinder 2, a driven gear 51 meshing with the lower gear ring 103 is provided at the end of the rotating shaft 5, a stirring frame 52 located in the cleaning cylinder 2 is provided on the rotating shaft 5, and a material discharge frame 201 is provided at the bottom of the cleaning cylinder 2.

[0033] Specifically, the adjustment mechanism 4 includes a discharge pipe 401 connected to the perforation 31, an embedded groove 402 is provided on the top of the discharge pipe 401, and a sealing plate 403 is provided in the embedded groove 402. The embedded groove 402 allows the sealing plate 403 to be embedded therein, so that the sealing plate 403 can provide a blocking effect for the perforation 31 and the top of the discharge pipe 401, thereby preventing waste plastic from being discharged through the discharge pipe 401 when it is not cleaned.

[0034] Specifically, a connecting plate 404 is provided at the end of the sealing plate 403, an adjusting shaft 405 is provided on the discharge pipe 401, a reciprocating wire groove 4051 is opened on the adjusting shaft 405 and the reciprocating wire groove 4051 is threadedly mounted on the connecting plate 404, and a driving motor 406 installed on the outside of the cleaning box 1 is provided at the end of the adjusting shaft 405. Through the transmission action of the output shaft of the driving motor 406, the rotation of the adjusting shaft 405 can drive the sealing plate 403 to move through the reciprocating wire groove 4051, so as to adjust the position of the sealing plate 403.

[0035] Specifically, a top cover 6 is provided on the top of the adjusting mechanism 4, and a water inlet pipe 61 and a feeding port 62 are provided on the top cover 6. A mounting frame 32 is provided on the bottom surface of the stabilizing plate 3 to provide stability for the adjusting shaft 405. Clean water can be introduced into the interior of the cleaning cylinder 2 through the water inlet pipe 61, and waste plastics that need to be cleaned can be introduced into the interior of the cleaning cylinder 2 through the feeding port 62.

[0036] Specifically, a blocking cover 621 is rotatably sleeved on the feeding port 62, and the end of the blocking cover 621 is rotatably connected to the top cover 6. The blocking cover 621 is opened by rotation, and is rotated through the connecting column between it and the top cover 6. When the cleaning cylinder 2 is performing a cleaning operation on the waste plastic, the waste water in the waste plastic box will not overflow through the feeding port 62.

[0037] Specifically, a balancing frame 104 is provided on the top of the top cover 6, and the balancing frame 104 is installed on the top of the cleaning box 1. The balancing frame 104 provides stability for the installation of the top cover 6, so that when the cleaning cylinder 2 rotates, the top cover 6 will not rotate with the cleaning cylinder 2.

[0038] Specifically, an outer gear ring 22 is provided on the cleaning cylinder 2, a speed control motor 71 is provided on the balance frame 104, and a driving gear 7 meshing and matching with the outer gear ring 22 is provided at the end of the output shaft of the speed control motor 71. By adjusting the rotation of the output shaft of the speed control motor 71, the driving gear 7 can be meshed and matched with the outer gear ring 22, so that the outer gear ring 22 can drive the cleaning cylinder 2 to rotate inside the cleaning box 1. The cleaning cylinder 2 can be rotated more slowly during the cleaning stage, and the speed of the output shaft of the speed control motor 71 can be increased relative to the driving gear 7 during the centrifugal dehydration stage, so that the waste plastic loaded inside the cleaning cylinder 2 can be centrifugally dehydrated.

[0039] Working principle: In the utility model, the baffle cover 621 is first rotated around the connecting axis between the baffle cover 621 and the top cover 6, so that the feeding port 62 is in an open state, and then the water inlet pipe 61 is connected with the external cleaning water pipeline, and then the waste plastics to be cleaned are put into the interior of the cleaning cylinder 2 through the feeding port 62, and cleaning water is simultaneously introduced into the interior of the cleaning cylinder 2;

[0040] Turn on the speed control motor 71, so that the output shaft of the speed control motor 71 can drive the driving gear 7 to rotate, thereby driving the cleaning cylinder 2 to rotate inside the cleaning box 1 by relying on the outer gear ring 22. When the cleaning cylinder 2 rotates, the stabilizing plate 3 and the top cover 6 will not rotate together with the cleaning cylinder 2;

[0041] When the cleaning cylinder 2 rotates, the driven gear 51 can mesh with the lower gear ring 103, so that the driven gear 51 can drive the rotating shaft 5 to rotate, so that the stirring frame 52 can vertically stir the waste plastic inside the cleaning cylinder 2, thereby improving the cleaning efficiency;

[0042] During the rotation of the cleaning cylinder 2, the unloading rack 201 can cooperate with the rotation of the cleaning cylinder 2 to move the plastic at the bottom of the cleaning cylinder 2, thereby improving the cleaning efficiency.

[0043] After cleaning is completed, the high-speed mode of the output shaft of the speed-controlled motor 71 is turned on, so that the rotation speed of the cleaning cylinder 2 driven by the outer gear ring 22 is increased, and the sewage inside the cleaning box 1 is discharged through the sewage pipe 101 at the same time, so that the waste plastic inside the cleaning cylinder 2 can be centrifuged to remove excess water. After the centrifugal dehydration treatment is completed, the drive motor 406 can be turned on, and the output shaft of the drive motor 406 drives the adjustment shaft 405 to rotate, so that the sealing plate 403 can be withdrawn from the embedded groove 402, opening the passage of the perforation 31 and the discharge pipe 401, and synchronously through the push of the unloading rack 201, the plastic inside the cleaning cylinder 2 can be discharged and collected through the perforation 31 and the discharge pipe 401 for subsequent treatment.
