Description

Technical Field

[0001] The utility model relates to the technical field of waste plastic bottle recycling equipment, in particular to a drum-type waste plastic bottle chip cleaning device. Background Art

[0002] A plastic bottle is a plastic container made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. It is mainly used for disposable plastic packaging of liquids or solids such as beverages, foods, pickles, honey, dried fruits, edible oils, agricultural and veterinary drugs, etc. For environmental protection and resource recycling, some used plastic bottles need to be recycled. In the process of mechanical recycling, first, the waste plastic bottles are crushed, cleaned, melted, etc., and then made into granular recycled plastic raw materials for the production of new plastic products. In the process of cleaning the plastic bottle chips, professional cleaning equipment is required.

[0003] In the prior art, there is a drum-type waste plastic bottle chip cleaning device (publication number: CN220697621U), and its structure includes a device main body. A top cover is installed on the top of the device main body, a handle is installed on the top of the top cover, a controller is installed at the front end of the device main body, a cleaning mechanism for quickly separating the waste plastic bottle chips after cleaning is installed in the middle of the inner side of the device main body, and a drying mechanism for accelerating the drying speed of the waste plastic bottle chips is installed at the top of the inner side of the device main body. Although the drum-type waste plastic bottle chip cleaning device drives the separation disk to move upward by setting a threaded column, when the threaded column rotates, the waste plastic bottle chips are filtered and separated from the water, so that the waste plastic bottle chips are located at the top of the drum, which is convenient for quickly taking out the waste plastic bottle chips, improving the taking-out speed and efficiency of the waste plastic bottle chips. At the same time, the water flowing down from the waste plastic bottle chips is conducted downward through the through holes, avoiding water accumulation on the top of the separation disk, which is convenient for subsequent drying operations.

[0004] However, in the actual use process, the plastic bottle chips are easy to accumulate on the top of the separation disk in the drum after entering the drum. The gaps between the accumulated plastic bottle chips are small, and it is easy to cause incomplete flushing when flushing with water. Moreover, the impurities after flushing will also move downward to form sediment accumulation, which makes the cleaning effect of the plastic bottle chips at the bottom worse, and is more likely to cause blockage of the through holes for draining water on the separation disk, affecting the overall cleaning effect of the plastic bottle chips.

A support ring is installed on the inner wall of the cleaning frame 101. The side of the cleaning cylinder 4 far away from opening one is rotationally connected to the inner wall of the support ring. Thus, the two ends of the cleaning cylinder 4 can be supported by the support ring and the protective shell 3.

[0025] As Figure 2 shown in the figure, a flushing assembly is arranged on the cleaning outer shell. The flushing assembly uses a water pump 8 as a driving element, and sprays water flow onto the plastic bottle chips inside the cleaning cylinder 4 through a nozzle to complete the cleaning operation. The flushing assembly is composed of a water pump 8, a water guide pipe 9, and a nozzle. The water pump 8 is arranged on one side of the cleaning frame 101. The inlet pipe on the water pump 8 is communicated with the lower chamber of the cleaning frame 101. The water guide pipe 9 is arranged on the cleaning frame 101. One end of the water guide pipe 9 is connected to the water pump 8. The other end of the water guide pipe 9 is arranged in an arc shape outside the cleaning cylinder 4, and the end of the water guide pipe 9 far away from the water pump 8 is in a multi-branch pipe shape, which is convenient for increasing the spraying area of the nozzle. The nozzle is arranged on the water guide pipe 9.

[0026] As Figure 2 and Figure 5As shown in the figure, a rotating assembly is provided on the cleaning housing 1. The rotating assembly uses a rotating motor 6 as a driving element and drives the cleaning cylinder 4 to rotate through a gear meshing method to ensure comprehensive cleaning of the plastic bottle chips in the cleaning cylinder 4. A protective housing 3 is provided on the cleaning housing. The protective housing 3 is connected to the cleaning baffle 102. The cleaning cylinder 4 is rotatably connected to the protective housing 3. The rotating assembly is located inside the protective housing 3. The rotating assembly is composed of a rotating motor 6, a rack ring 5, and a gear 7. The rotating motor 6 is arranged inside the protective housing 3. The rack ring 5 is sleeved on the cleaning cylinder 4. The gear 7 is sleeved on the output shaft of the rotating motor 6. The gear 7 is meshed and connected to the rack ring 5. Through the setting of the protective housing 3, the rotating assembly can be protected to avoid the influence of water flow on the rotating assembly. An arc-shaped water return groove is opened on the protective housing 3. A part of the arc-shaped water return groove extends to the cleaning baffle 102. An arc-shaped water return frame 16 is installed in the arc-shaped water return groove. Through the arc-shaped water return frame 16, protection can be formed on one side of the cleaning cylinder 4 to avoid some water flow in the cleaning cylinder 4 from flowing to the outside of the cleaning baffle 102. Both the bottom and the top of the arc-shaped water return frame 16 are set as openings three, and a filter screen is arranged in the opening three at the top.

[0027] As Figure 2 shown, a discharge tray 12 is arranged inside the cleaning cylinder 4. A push cylinder 14 is installed on the cleaning frame 101. The telescopic shaft of the push cylinder 14 extends into the cleaning frame 101. A push rod 13 is arranged on the cleaning frame 101. One end of the push rod 13 is rotatably connected to the telescopic shaft of the push cylinder 14. The push rod 13 and the telescopic shaft of the push cylinder 14 can be connected by a rotating joint. The other end of the push rod 13 extends into the cleaning cylinder 4 and is connected to the discharge tray 12. The push rod 13 is in a sliding state with the cleaning cylinder 4. Collision rollers 15 are installed on the discharge tray 12. The collision rollers 15 are of a polygonal shape. Through the setting of the collision rollers 15, collisions can occur between the plastic bottle chips and the collision rollers 15 during the process of the plastic bottle chips falling from a high place, so as to separate the plastic bottle chips stuck together, which can improve the cleaning effect of the plastic bottle chips.

[0028] As Figure 2 and Figure 3 shown, an opening two is opened on one side of the cleaning frame 101. A filter frame 10 is arranged inside the cleaning frame 101 for filtering the cleaned water flow. One side of the filter frame 10 extends out of the cleaning frame 101 and is connected to the cleaning frame 101 by bolts.

The feeding hopper 203 is installed on the blocking plate 202, and the bottom end of the feeding hopper 203 is obliquely arranged to facilitate the transportation of plastic bottle flakes into the cleaning cylinder 4. The lowest point of the feeding hopper 203 should be higher than the axis point of the cleaning cylinder 4, so as to prevent the plastic bottle flakes from accumulating in the feeding hopper 203. Moreover, the amount of plastic bottle flakes to be cleaned each time needs to be limited to prevent the plastic bottle flakes from accumulating in the feeding hopper 203 due to excessive cleaning amount. At the same time, a certain amount of plastic bottle flakes can be better cleaned during cleaning. The cleaning amount of the plastic bottle flakes needs to be no more than half of the capacity of the cleaning cylinder 4. The lifting cylinder 204 is installed on the fixing frame 201, and the telescopic shaft of the lifting cylinder 204 is connected to the blocking plate 202 to control the lifting of the blocking plate 202.

[0030] In this embodiment, when cleaning the plastic bottle flakes, the blocking plate 202 is in a state of blocking the cleaning cylinder 4. At this time, the plastic bottle flakes can be transported into the cleaning cylinder 4 through the feeding hopper 203. Then, start the water pump 8 to pump water, and spray it onto the cleaning cylinder 4 through the water guide pipe 9 and the nozzle, and act on the plastic bottle flakes through the flushing holes on the cleaning cylinder 4. Then start the rotating motor 6, and drive the cleaning cylinder 4 to rotate through the gear 7 and the rack ring 5. During the rotation of the cleaning cylinder 4, the plastic bottle flakes at the bottom can be driven to move by the multiple partitions 11 and fall when at a high position. Thus, the plastic bottle flakes in the cleaning cylinder 4 will not form a pile during cleaning, and the plastic bottle flakes falling from a high position are in a dispersed state with a large gap, so that the cleaning of the plastic bottle flakes can be better completed. After the cleaning is completed, the lifting cylinder 204 can drive the blocking plate 202 to rise to a suitable height, and then the pushing cylinder 14 can be started to push the discharge tray 12 to move through the push rod 13, and push the plastic bottle flakes in the cleaning cylinder 4 out of the cleaning cylinder 4, thus completing the cleaning operation of the plastic bottle flakes.
