Description

Technical Field

[0001] The present invention relates to the technical field of PET bottle flake processing, in particular to a PET bottle flake cleaning and drying processing device and a use method thereof. Background Art

[0002] PET plastic bottles are not only widely used to package carbonated beverages, drinking water, juice, enzymes, and tea beverages, making them the most widely used beverage packaging today, but are also widely used in many other fields, including food, chemical, and pharmaceutical packaging. PET plastic has a wide range of applications in the packaging field, whether it is packaging film or coiled material. However, when these materials are discarded, they face the problem of how to deal with them.

[0003] Although a large number of PET plastic bottles are currently discarded, the PET material itself is one of the raw materials for products in various fields. Therefore, the discarded PET plastic bottles will be recycled and become raw materials in other fields. The existing recycling process generally involves crushing the PET plastic bottles and then washing and drying the PET bottle flakes. Although the current recycling and processing equipment is very complete, it still has obvious defects in actual use, such as:

[0004] After the PET bottle flakes are crushed, they are directly put into the washing tank for cleaning. However, a large amount of dust is generated during the crushing process, so this dust will enter the tank along with the PET bottle flakes. In addition, there are stirring blades inside the tank, so this dust will not settle but will quickly spread in the tank. As a result, after the PET bottle flakes are picked up after cleaning, a large amount of dust will still be attached to the surface and taken out together. Moreover, after entering the tank, the PET bottle flakes will always float on the water surface. The stirring blades on the water surface alone will push the PET bottle flakes forward, but there will be no effective cleaning force on the surface of the PET bottle flakes. As a result, most of the PET bottle flakes are only washed away by the dust on the surface, and they cannot be effectively cleaned.

[0005] Therefore, a kind of PET bottle flake cleaning and drying processing device that designs and can improve cleaning quality is now designed to solve this type of defect. Summary of the Invention

[0045] The present invention also discloses a method for using the PET bottle flake cleaning and drying processing device, which specifically includes the following steps:

[0046] S1, bottle flake dust removal: using the operation box 201 to remove the dust mixed in the PET bottle flakes;

[0047] S2, bottle flakes cleaning: the dust-removed PET bottle flakes are sequentially put into the first cleaning tank 101 and the second cleaning tank 102, and then respectively cleaned and rinsed;

[0048] S3, bottle flake drying: the cleaned PET bottle flakes are put into the conveying cylinder 204 for drying.

[0049] The method for using the above-mentioned PET bottle flake cleaning and drying processing device includes the following more specific steps:

[0050] S1. Dust removal of bottle flakes: Before processing PET bottle flakes, water is firstly poured into the first cleaning tank 101 and the second cleaning tank 102, and the fluidity of the water in the first cleaning tank 101 and the second cleaning tank 102 is maintained. The water in the second cleaning tank 102 is poured into the water by the material pump 122. Then the second motor 210 is started to drive the auger blade 212 to rotate by the second rotating rod 211. At the same time, the worm 121 is also driven to rotate by the transmission of the pulley 208 and the belt 209. Then, the crushed PET bottle flakes are put into the storage hopper 222. Then, the arc-shaped push plate 213 is driven by the second rotating rod 211 to continuously push the rebound rod 225. Then, the sliding action of the slider seat 220 drives the storage hopper 222 to swing left and right, so that the PET bottle flakes in the storage hopper 222 fall into the powder blowing trough 203. At the same time, the U-shaped pounding blade 224 is in a stationary state and can hit the PET bottle flakes with the moving storage hopper 222 to avoid PET bottle flakes. The PET bottle flakes are blocked, and the U-shaped pounding blade 224 can also ensure that the PET bottle flakes fall in bulk. When the PET bottle flakes fall into the powder blowing trough 203, they are buffered by the blocking of the guide inclined plate 215. At the same time, the fan 230 is started to blow air on the falling PET bottle flakes, and then the dust inside the PET bottle flakes is blown through the screening mesh 229 into the powder cleaning trough 202. Then the nozzle 226 uses the water pump to spray water, so that the water flows along the powder cleaning trough 203. 2, and when the dust contacts the inner wall of the powder cleaning tank 202, it will be driven by the water through the drainage bottom pipe 228 and flow into the inner side of the water receiving bottom frame 227 for discharge. Then, the PET bottle flakes fall to the bottom and are driven by the auger blades 212 to be transported. Then, when the material pump 122 is started, it will pump water through the liquid pumping main pipe 123. When the PET bottle flakes move to the feeding rectangular pipe 124, the liquid pumping main pipe 123 will drive the PET bottle flakes to be transported to the inside of the second cleaning tank 102 for cleaning.

[0051] S2. Bottle flakes cleaning: After the PET bottle flakes enter the second cleaning tank 102, they move forward along the water flow. At this time, as the cylinder 107 is started and drives the two bag frames 110 to rise, the docking tube 113 docks with the docking head 118, and then drives the L-shaped baffles 119 on both sides to rise to the top of the first cleaning tank 101 and the second cleaning tank 102. After the L-shaped baffles 119 rise to the top, the PET bottle flakes are no longer blocked and continue to move forward. When several L-shaped baffles 119 are lowered, they will push the bottom of each The PET bottle flakes are pressed into the water, and then the rotating stirring blades 105 will vigorously clean the PET bottle flakes. When the L-shaped baffle 119 rises again to make the PET bottle flakes float again, the L-shaped baffle 119 uses the thrust of the inclined portion 120 when it rises to push it to move forward for a distance when it rises. After several stops of the L-shaped baffles 119 and the strong cleaning of the stirring blades 105, the PET bottle flakes are cleaned more thoroughly. Until the PET bottle flakes are pushed to the front of the second cleaning tank 102, as the material is picked up, The frame 110 rises again to pick up the PET bottle pieces, and the docking tube 113 will dock with the docking head 118 when the bag material frame 110 rises to the top of the first cleaning tank 101 and the second cleaning tank 102. When the bag material frame 110 rises to the top, the first motor 108 is started to drive the cylinder 107 to rotate 180 degrees so that the two bag material frames 110 exchange positions with each other, and during the rotation, the diamond-shaped pressing plate 114 will squeeze the L-shaped circular plate 218, so that the horizontal push rod 216 pushes the special-shaped scraper 2 17 moves backward to push and separate the dust on the top of the guiding inclined plate 215, and uses the fan 230 to blow it into the powder cleaning tank 202. The bag frame 110 after changing its position follows the cylinder 107 to descend. After the bag frame 110 descends into the first cleaning tank 101, the top of the upper push rod 126 passes through the round socket 112 and lifts the material supporting mesh plate 111, thereby quickly pushing the PET bottle flakes to the water surface. The PET bottle flakes continue to move and pass through the L-shaped baffle 119 and the stirring blade 105 for strong rinsing again;

[0052] S3. Bottle flake drying: When the PET bottle flakes move to the rear of the first cleaning tank 101, the water on the top and the PET bottle flakes enter the L-shaped material guide frame 125 and flow to the inner side of the drain groove 205. At this time, the water will directly pass through the drain groove 205 and enter the water receiving bottom frame 227 for discharge. The auger blades 212 drive the cleaned PET bottle flakes forward, and the electric heater 214 heats and dries the PET bottle flakes until the PET bottle flakes move to the front of the conveying cylinder 204 and are discharged through the blanking bottom groove 207.

[0053] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.
