Description

Technical Field

[0001] This utility model relates to the field of waste plastic bags, specifically to a waste plastic bag recycling and impurity removal device. Background Technology

[0002] Waste plastic bags refer to discarded or no longer used plastic bags. These plastic bags mainly come from various fields such as daily life, commercial activities, and agricultural production. Waste plastic bag recycling is an important environmental issue, aiming to reduce the pollution of plastic bags to the environment and realize the recycling of resources. The impurity removal device in the waste plastic bag recycling process plays a crucial role. It can efficiently remove impurities from plastic bags and improve the quality of recycled plastics.

[0003] A search revealed a waste plastic bag recycling device (publication number CN221736778U). This device includes a recycling bin with a compression chamber at the top and a placement slot at the top of the bin. The placement slot is located on one side of the top of the compression chamber and has an inclined bottom. Side plates are fixedly connected to both ends of the top of the recycling bin and are located at both ends of the placement slot. A compression mechanism is located at the top of the recycling bin. A discharge port is located on one side of the recycling bin's surface and is connected to the inside of the compression chamber. A discharge mechanism is located inside the discharge port. A base is fixedly connected to the bottom of the recycling bin, and a control box is installed at one end of the recycling bin's surface. This invention, through the design of an L-shaped flap, allows the compressed plastic bags inside the compression chamber to be transported to the outside of the recycling bin after compression, facilitating the unified collection of plastic bags.

[0004] Existing waste plastic bag recycling devices suffer from various drawbacks during use. Because waste plastic bags vary in size, attempting to remove impurities from a single bag is inefficient due to their large size, making effective separation difficult. Furthermore, the lack of wind power and suction from a crusher makes it difficult to remove impurities attached to the plastic bag fragments, reducing the purity of the recycled bags. In the comparative case mentioned above, the waste plastic bag recycling devices also lack the ability to further crush the waste plastic bags to improve recycling efficiency. Therefore, with long-term use, the recycled plastic bags require additional processing steps to remove impurities due to insufficient purity, further increasing costs.

[0005] Therefore, it is necessary to invent a waste plastic bag recycling and impurity removal device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a waste plastic bag recycling and impurity removal device. It achieves impurity removal through a removal box, a crushing box, a crushing roller, a vacuum pump, an air inlet, a crushing and suction machine, a storage box, and a crushing and suction port. The rotating crushing roller crushes the waste plastic bags and impurities, rapidly reducing the size of the plastic bags and making the subsequent impurity removal process more efficient. Furthermore, the high degree of automation in the crushing, impurity removal, and collection processes reduces manual intervention, lowers labor intensity, and improves recycling efficiency. Simultaneously, through fine impurity removal, the recycled plastic bags are more suitable for reuse or further processing, thus solving the problems of existing waste plastic bag recycling technologies. During the use of recycling impurity removal devices, due to the varying sizes of waste plastic bags, removing impurities as a whole is difficult because the bags are too large to effectively separate impurities, thus reducing removal efficiency. Furthermore, the lack of wind power and suction from the crusher makes it difficult to remove impurities attached to the plastic bag fragments, reducing the purity of the recycled plastic bags. In the comparative case mentioned above, the waste plastic bag recycling impurity removal devices also lack the ability to further crush the waste plastic bags to improve recycling efficiency. Therefore, with long-term use, the recycled plastic bags require additional processing steps to remove impurities due to insufficient purity, further increasing costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste plastic bag recycling impurity removal device, including an impurity removal box, which is used as the main body for removing impurities from waste plastic bags;

[0008] A crushing chamber is located above a cleaning chamber and is used to crush waste plastic bags. A feeding port is provided at the top of the crushing chamber. A crushing roller is rotatably connected inside the crushing chamber. Fixed plates are fixedly installed on both sides of the outside of the cleaning chamber. A vacuum pump is fixedly installed above the fixed plates. An air blowing pipe is fixedly installed at the output end of the vacuum pump, and an air blowing port is fixedly connected to the other end of the air blowing pipe.

[0009] An installation plate is set on the outside of the impurity removal box for connecting and installing a crushing and suction machine. A feeding pipe is fixedly installed at the output end of the crushing and suction machine, and a storage box is fixedly installed at the other end of the feeding pipe. A crushing and suction port is fixedly connected to the outside of the crushing and suction machine, and a support frame is fixedly installed on the top of the impurity removal box.

[0010] Preferably, the crushing chamber is fixedly connected to the impurity removal chamber, and the crushing roller is movably connected to the crushing chamber.

[0011] Preferably, the storage box is fixedly connected to the mounting plate, and the debris suction port is symmetrically arranged with respect to the central axis of the debris removal box.

[0012] Preferably, a waste box is fixedly installed on the top of the support frame, and a filter cartridge frame is fixedly installed on the outside of the support frame.

[0013] Preferably, the filter cartridge frame has an annular groove inside, an annular block is slidably connected inside the annular groove, a filter cartridge for removing impurities is fixedly installed outside the annular block, and a first turntable is fixedly installed outside the filter cartridge for removing impurities.

[0014] Preferably, a transmission belt is movably connected to the outside of the first turntable, and a second turntable is movably connected to the other end of the transmission belt. A servo motor is fixedly installed on the outside of the second turntable.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model is equipped with a waste removal box, a crushing box, a crushing roller, a vacuum pump, an air blowing port, a crushing and suction machine, a storage box, and a crushing and suction port. When using this waste plastic bag recycling waste removal device, the waste plastic bags and temporarily retained impurities entering the crushing box are crushed by the rotating crushing roller. The waste plastic bag fragments and impurities fall together in the waste removal box. Since a filter screen is also installed inside the crushing box, the waste plastic bag fragments fall into the filter screen, while the impurities pass through the filter screen and flow out from the bottom of the crushing box. Then, the vacuum pump provides a certain amount of air force to the air blowing port, blowing the waste plastic bag fragments on the filter screen. The process further separates the impurities adhering to the waste plastic bag fragments from the waste plastic bag fragments. Then, the crushing and suction machine provides suction to the crushing and suction port to suck up all the waste plastic bag fragments and store them in the storage box. This impurity removal method can quickly reduce the size of plastic bags by crushing waste plastic bags and impurities through rotating crushing rollers, making the subsequent impurity removal process more efficient. Moreover, the high degree of automation in the crushing, impurity removal and collection process reduces manual intervention, reduces labor intensity, and improves recycling efficiency. At the same time, through fine impurity removal, the recycled plastic bags are more suitable for reuse or further processing.

[0017] 2. This utility model is equipped with a filter cylinder frame, annular groove, annular block, impurity removal filter cylinder, first turntable, transmission belt, second turntable, and servo motor. When using this waste plastic bag recycling impurity removal device, a filter cylinder frame is also set above the crushing chamber. The waste plastic bags to be removed are first uniformly stuffed into the impurity removal filter cylinder. The rotation of the first and second turntables drives the impurity removal filter cylinder to rotate. In this way, the waste plastic bags inside the impurity removal filter cylinder are affected by the rotation, and the impurities inside the waste plastic bags are thrown out and separated. In this way, the impurities are effectively thrown out under the action of centrifugal force, realizing a fast and efficient impurity removal process. Moreover, the waste plastic bags are pre-removed before crushing, reducing the amount of impurities entering the crushing chamber, thereby reducing the wear and load of the crushing equipment, and providing purer waste plastic bag raw materials for subsequent crushing and further impurity removal.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The device shown is a waste plastic bag recycling and impurity removal device, including an impurity removal box 1, which is used for the main body of waste plastic bag impurity removal;

[0028] The crushing box 2 is located above the impurity removal box 1 and is used to crush waste plastic bags. The crushing box 2 has a feeding port 3 on its top. The crushing box 2 is rotatably connected to the crushing roller 4. The impurity removal box 1 is fixedly installed on both sides of the outside with fixed plates 5. The fixed plate 5 is fixedly installed on the top of the fixed plate 5. The output end of the vacuum pump 6 is fixedly installed with an air blowing pipe 7. The other end of the air blowing pipe 7 is fixedly connected with an air blowing port 8.

[0029] Mounting plate 9, located outside the impurity removal chamber 1, is used to connect and mount the crusher 10. A feeding pipe 11 is fixedly mounted at the output end of the crusher 10, and a storage box 12 is fixedly mounted at the other end of the feeding pipe 11. A crushing suction port 13 is fixedly connected to the outside of the crusher 10. A support frame 14 is fixedly mounted on the top of the impurity removal chamber 1. Waste plastic bags and temporarily retained impurities entering the crushing chamber 2 are crushed by the rotating crushing roller 4. The waste plastic bag fragments and impurities then fall together into the impurity removal chamber 1. As the crushing chamber 2 is equipped with a filter, the waste plastic bag fragments fall onto the filter, while the impurities pass through the filter and flow out from the bottom of the crushing chamber 2. Then, the vacuum pump 6 provides a certain amount of air force to the air outlet 8 to blow the waste plastic bag fragments on the filter, further separating the impurities adhering to the waste plastic bag fragments from the waste plastic bag fragments. Then, the crushing suction machine 10 provides suction force to the crushing suction port 13 to suck all the waste plastic bag fragments into the storage box 12.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the crushing box 2 is fixedly connected to the impurity removal box 1, and the crushing roller 4 is movably connected to the crushing box 2. By rotating the crushing roller 4, waste plastic bags and impurities are crushed, which can quickly reduce the size of the plastic bags and make the subsequent impurity removal process more efficient. The storage box 12 is fixedly connected to the mounting plate 9, and the crushing suction port 13 is symmetrically arranged with respect to the central axis of the impurity removal box 1. The high degree of automation of the crushing, impurity removal and collection process reduces manual intervention, reduces labor intensity and improves recycling efficiency.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, a waste box 15 is fixedly installed above the support frame 14, and a filter cartridge frame 16 is fixedly installed on the outside of the support frame 14. The filter cartridge frame 16 is used to support the impurity removal filter cartridge 19 to rotate inside, thereby facilitating the removal of internal impurities. An annular groove 17 is opened inside the filter cartridge frame 16, and an annular block 18 is slidably connected inside the annular groove 17. The impurity removal filter cartridge 19 is fixedly installed on the outside of the annular block 18, and a first turntable 20 is fixedly installed on the outside of the impurity removal filter cartridge 19. Waste plastic bags for impurity removal are first uniformly stuffed into the impurity removal filter cartridge 19, and then passed through the first turntable 20 and the second turntable. The rotation of 22 drives the impurity removal filter cartridge 19 to rotate, so that the waste plastic bags inside the impurity removal filter cartridge 19 are affected by the rotation, and the impurities inside the waste plastic bags are thrown out and separated. The first turntable 20 is movably connected to the outside of the transmission belt 21, and the other end of the transmission belt 21 is movably connected to the second turntable 22. The second turntable 22 is fixedly installed on the outside of the servo motor 23. The impurities are effectively thrown out under the action of centrifugal force, realizing a fast and efficient impurity removal process. Moreover, the waste plastic bags are pre-removed before crushing, reducing the amount of impurities entering the crushing box 2.

[0032] The working principle of this product is as follows: First, connect the external power supply, take out the waste plastic bags that need to be cleaned, and stuff the waste plastic bags into the cleaning filter cartridge 19. Then, turn on the servo motor 23, so that the rotation of the first turntable 20 and the second turntable 22 drives the cleaning filter cartridge 19 to rotate on the filter cartridge frame 16. In this way, the impurities are effectively thrown out under the action of centrifugal force, realizing a fast and efficient cleaning process. Moreover, the pre-cleaning of the waste plastic bags before crushing reduces the amount of impurities entering the crushing chamber 2, thereby reducing the wear of the crushing equipment. After pretreatment, the waste plastic bags are removed from the impurity removal filter cartridge 19 and put into the crushing chamber 2. The waste plastic bags and temporarily retained impurities in the crushing chamber 2 are crushed by the rotating crushing roller 4. The waste plastic bag fragments and impurities fall together in the impurity removal chamber 1. Then, because a filter screen is installed inside the crushing chamber 2, the waste plastic bag fragments fall onto the filter screen, while the impurities pass through the filter screen and flow out from the bottom of the crushing chamber 2. Then, the vacuum pump 6 is turned on, and the vacuum pump 6 provides a certain amount of air force to the air outlet 8 to blow... The waste plastic bag fragments on the filter screen are further separated from the waste plastic bag fragments by removing impurities. Then, the switch of the crusher 10 is turned on, and the crusher 10 provides suction to the crushing port 13 to suck up all the waste plastic bag fragments and store them in the storage box 12. This impurity removal method uses the rotating crushing roller 4 to crush the waste plastic bags and impurities, which can quickly reduce the size of the plastic bags and make the subsequent impurity removal process more efficient. Moreover, the high degree of automation of the crushing, impurity removal and collection process reduces manual intervention, reduces labor intensity and improves recycling efficiency. After removing the impurity removed waste plastic bags from the storage box 12 of the waste plastic bag recycling impurity removal device, the waste plastic bag recycling impurity removal work can continue. Finally, after completing the installation and use of the waste plastic bag recycling impurity removal device according to the above operations, turn off the switch of the vacuum pump 6, the switch of the crusher 10, and the switch of the servo motor 23. If it is not used for a long time, simply disconnect the external power supply. In this way, the use of the waste plastic bag recycling impurity removal device is completed.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
