Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling and processing, in particular to a device for cleaning and dehydrating crushed plastics. Background Art

[0002] In the current context of environmental protection and resource recycling, the recycling and treatment of plastic waste is particularly important. Plastic, as a widely used material, is widely used in all aspects of daily life due to its durability and diversity. However, the treatment and recycling of plastic waste faces major challenges. Traditionally, the process of processing recycled plastics includes key steps such as crushing, washing and dehydration to ensure the quality of recycled materials and meet the basic requirements for reuse. However, existing equipment often has problems such as inefficiency and limited processing capacity when handling these steps, which not only affects the recycling efficiency, but also reduces the quality of recycled materials, thereby limiting the extensiveness and economy of plastic waste recycling.

[0003] The functions of the plastic crushing equipment currently on the market are relatively simple, and usually multiple different equipment are required to work together to complete pre-processing steps such as cleaning and dehydration. This treatment method requires manual or mechanical transfer of crushed plastic waste from one device to another for further processing, which not only increases labor costs but also greatly reduces processing efficiency. In addition, this segmented processing process is prone to secondary contamination of materials during the transfer process, affecting the quality of the final recycled materials.

[0004] Furthermore, the existing cleaning and dehydration equipment has deficiencies in design and process, making it difficult to achieve efficient and high-quality processing of plastic crushed materials. For example, traditional cleaning equipment is often unable to completely remove pollutants such as oil stains and label residues on the surface of the crushed materials, and dehydration equipment is also difficult to completely remove the moisture in the materials after cleaning, all of which directly affect the reuse value of plastic crushed materials. In addition, traditional equipment mostly adopts batch processing, that is, each time a certain amount of material is processed, the machine needs to be stopped to unload, and then reloaded to start a new round of processing. This intermittent operation method seriously affects the continuity and efficiency of processing.

[0005] In view of the above problems, it is urgent to develop an integrated processing equipment that can realize continuous and automatic cleaning and dehydration of plastic crushed materials to improve the processing efficiency and material quality, and improve the cleaning and dehydration efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] See also Figure 1-6 A plastic crushing material cleaning and dehydration equipment comprises a cleaning part 1 and a dehydration part 2 connected in sequence; the cleaning part 1 comprises a cleaning box 11 and a transmission component and a cleaning brush roller 13 assembled in the cleaning box 11; the cleaning box 11 comprises a cleaning area and a settling area 112 arranged on the downstream side of the cleaning area; the transmission component is assembled in the cleaning area; the cleaning brush roller 13 is evenly arranged above the transmission component and keeps linkage with the transmission component.

[0030] The dehydration section 2 includes an isolation cylinder 21, a dehydration cylinder 22, and an air distribution duct 23. The two ends of the isolation cylinder 21 are respectively equipped with a loading interface 211 and a unloading interface 212. The dehydration cylinder 22 is rotatably installed in the isolation cylinder 21 and the two ends are respectively connected with the loading interface 211 and the unloading interface 212. The dehydration cylinder 22 is fixed with spiral blades 221 distributed in a circular array. Filter holes are evenly arranged on the side walls of the dehydration cylinder 22. The isolation cylinder 21 is equipped with an air collecting hood 213 and a water collecting hood 214 respectively arranged on the upper and lower sides of the dehydration cylinder 22. The air distribution duct 23 is installed at the bottom of the isolation cylinder 21, and the air distribution duct 23 is evenly provided with hot air nozzles 231 arranged toward the dehydration cylinder 22.

[0031] The collected waste and scraps are then crushed and sequentially passed through the cleaning section 1 and the dehydration section 2 to complete the cleaning and dehydration process, so as to realize the reuse of the waste plastics. The cleaning box 11 is filled with water and a cleaning agent for cleaning the waste and scraps, and the top of the cleaning box 11 is sealed to prevent the running cleaning brush roller 13 from causing water droplets to splash outward.

[0032] A feed hopper 113 arranged toward the transmission component is installed on the upstream side of the cleaning box 11. The crushed waste plastics are input into the cleaning box 11 from the feed hopper 113. Since the recycled waste plastics are mostly PVC, PET, PETE, PS and other composite materials, their density is greater than water. They will be transmitted to the transmission component in the cleaning area, and then driven by the transmission component to be transported downstream. In this process, the running cleaning brush roller 13 can perform multiple cleanings on the passing plastic crushed materials, and the cleaned plastic crushed materials are finally collected in the sedimentation area 112 downstream of the cleaning box 11.

[0033] The material in the sedimentation area 112 is transported from the feeding structure to the dewatering cylinder 22 installed in the isolation cylinder 21. During the operation of the dewatering cylinder 22, the spiral blades 221 installed on the inner wall of the dewatering cylinder 22 can drive the plastic crushed material to turn over and transport it to the lower material interface 212. In this process, the residual water carried by the crushed material will leak into the isolation cylinder 21 through the filter holes on the dewatering cylinder 22, and finally be collected in the water collecting cover 214 for external discharge. At the same time, the hot air in the air distribution pipe 23 is input upward by the hot air nozzle 231. The plastic particles are separated from the isolating cylinder 21 and enter the dehydrating cylinder 22 through the filter holes to efficiently dry the crushed materials transported therein. The temperature of the hot air after drying drops and the hot air carries moisture and flows upward, and is finally collected and discharged through the air collecting hood 213. After being dried, heated and other treatments, the hot air can be re-input through the air distribution duct 23 to achieve the recycling of the hot air. After being gravity dehydrated and dried with hot air, the crushed plastic particles are finally transported from the dehydrating cylinder 22 to the unloading interface 212, and finally discharged and collected from the unloading interface 212.

[0034] In order to achieve stable transmission of the crushed plastic in the cleaning box 11 to the loading interface 211 of the isolation cylinder 21, the following technical solution is provided.

[0035] The cleaning box 11 further includes a screw conveyor 3 , which is fixedly installed in the cleaning box 11 , and a feed end of the screw conveyor 3 is arranged in the settling area 112 , and a feed interface 211 is connected to a discharge end of the screw conveyor 3 .

[0036] With the help of the screw conveyor 3, the plastic crushed materials collected in the sedimentation area 112 of the cleaning box 11 can be stably conveyed to the feeding interface 211 of the isolation cylinder 21, so as to achieve the purpose of supplying the plastic crushed materials to the upstream section of the dehydration cylinder 22.

[0037] In order to ensure that the transmission components and the cleaning brush roller 13 can be stably installed and operated in the cleaning box 11 to complete the transmission and cleaning of the plastic crushed materials, the following technical solution is provided.

[0038] The transmission assembly includes a reduction motor 121, two groups of transmission rollers 122 rotatably installed in the cleaning box 11, and a transmission belt 123 wound around the periphery of the transmission rollers 122. The reduction motor 121 is fixedly installed on the outer wall of the cleaning box 11 and is dynamically connected to one group of transmission rollers 122; the cleaning brush roller 13 is rotatably installed on the side wall of the cleaning box 11, and the bristles of the cleaning brush roller 13 are in contact with the upper surface of the transmission belt 123.

[0039] When the reduction motor 121 is working, it drives the transmission roller 122 directly connected thereto to operate stably, and further drives the transmission belt 123 and another group of transmission rollers 122 to operate stably.

[0040] In order to ensure that the plastic crushed objects can be stably transported on the transmission belt 123 , ribs 1231 are evenly arranged on the transmission belt 123 . The ribs 1231 can provide support for the plastic crushed objects, ensuring that they are stably transported downstream driven by the transmission belt 123 .

[0041] In order to ensure the fluidity of clean water on both sides of the transmission belt 123 in the cleaning box 11, leakage holes are evenly opened on the transmission belt 123, which can ensure that the mixture of clean water and cleaning agent flows up and down while intercepting the plastic crushed materials.

[0042] In order to ensure that the transmission component can drive the cleaning brush roller 13 to operate, so as to achieve the coordinated work of the transmission component and the cleaning brush roller 13 to efficiently clean the plastic crushed materials, the following technical solution is provided.

[0043] The same end of each group of cleaning brush rollers 13 is fixedly connected to a transmission sprocket 131 arranged on the outside of the cleaning box 11. The transmission sprockets 131 on two adjacent groups of cleaning brush rollers 13 realize chain transmission through a chain. The end of one group of transmission rollers 122 is fixedly connected to a pulley A1221, and the end of one group of cleaning brush rollers 13 is fixedly connected to a pulley B132. The pulleys A1221 and B132 realize power transmission through a transmission belt 123.

[0044] The combination of the transmission sprocket 131 and the chain can ensure that the cleaning brush rollers 13 run synchronously. The combination of the two sets of pulleys and the transmission belt 123 can transmit the power of the transmission roller 122 to the cleaning brush roller 13, thereby driving the cleaning brush roller 13 to run stably.

[0045] The cleaning brush roller 13 and the transmission roller 122 have the same rotation direction, and since the effective diameter of the pulley A1221 is smaller than the pulley B132, the cleaning brush roller 13 can rotate slowly, which can extend the time for the plastic crushed material to pass through the cleaning brush roller 13 to improve its cleaning quality.

[0046] In order to ensure that the dehydration cylinder 22 can be stably installed and operated in the isolation cylinder 21, and to prevent the plastic crushed materials in the dehydration cylinder 22 from entering the middle section of the isolation cylinder 21 from the port of the dehydration cylinder 22, the following technical solution is provided.

[0047] A plurality of annular partitions 215 are fixedly connected in the isolation cylinder 21, and the dehydration cylinder 22 is rotatably installed in the annular partitions 215, and both ends of the dehydration cylinder 22 are sealed and fit with the annular partitions 215; the dehydration section 2 also includes a driving motor 24 fixedly installed on the outside of the isolation cylinder 21, and a driving bevel gear 241 arranged on the inside of the isolation cylinder 21 is fixedly connected to the output shaft of the driving motor 24, and a transmission bevel gear that meshes with the driving bevel gear 241 is fixedly connected to the outer wall of the dehydration cylinder 22.

[0048] The design of the annular partition 215 can ensure that the loading interface 211 and the unloading interface 212 are directly connected to the dewatering cylinder 22, thereby preventing the plastic crushed materials from entering the air collecting hood 213, the water collecting hood 214 and other parts in the isolation cylinder 21 from the loading interface 211 or the unloading interface 212.

[0049] The design of the annular partition 215 can also make the driving bevel gear 241 and the transmission bevel gear in a closed environment to prevent them from being disturbed by water vapor and affecting their service life. When the driving motor 24 drives the driving bevel gear 241 to run, the transmission bevel gear and the dehydration cylinder 22 can be driven to run stably.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
