[0012] Preferably, a concave disc with matching grooves is embedded and fixed at the other end of the branch pipe, and the concave disc is installed and connected to the drying cylinder via the through-hole matching disc. At the same time, the other end of the drying cylinder is also installed and connected to one end of the conveying pipe via the concave disc and the through-hole matching disc.

[0013] By adopting the above technical solution, the through-hole matching plate is provided to achieve the purpose of opening the snap-fit ​​installation.

[0014] Preferably, the other end of the delivery pipe passes through the bucket cover, extends inside the bucket cover and is installed and connected to the spray pipe, and a spray head is embedded and installed at the bottom of the spray pipe, and a first control valve is fixed on the upper and lower sides of the bucket cover.

[0015] By adopting the above technical solution, the bucket box cover is provided to play the role of opening and fixing the connection.

[0016] Preferably, the classification and collection component includes a port plate fixed on the first control valve, and a magnet bar is fixed to the bottom of the port plate, and the magnet bar is fixed to the through-hole frame by adsorption.

[0017] By adopting the above technical solution, the magnet strips are arranged to achieve adsorption and fixation.

[0018] Preferably, a connecting hole is provided inside the through hole frame, and the through hole frame is elastically rotated and adjusted with the adjustment plate through the connecting hole and the torsion spring.

[0019] By adopting the above technical solution, elastic adjustment is achieved through the torsion spring.

[0022] Preferably, a connecting plate is symmetrically fixed inside the mounting tube, and a cutting knife is obliquely fixed on the surface of the connecting plate and is rotatably adjusted relative to the piercing rod.

[0023] By adopting the above technical solution, the provided cutting knife can achieve relative rotation adjustment.

[0024] Compared with the prior art, the invention has the following beneficial effects: the recycled plastic sorting device with classification and drying and cleaning structure,

[0025] (1) In this case, the bottle flakes and label paper in the crushed material are separated by the following methods: a heating tube, a stirring shaft group, a first gear group and a rotating motor are set in the cleaning and drying components. This is usually completed after multiple rinsing processes, which causes a large amount of water resource waste. When the recycled plastic enters the inside of the bucket cover, the operator controls the heating tube to heat the cleaning water during operation, and the label paper adhered to the surface of the recycled plastic is heated synchronously during the heating of the cleaning water. When the label paper is heated, the label paper is separated from the surface of the recycled plastic, and the label paper absorbs water and settles at the bottom of the bucket cover for collection. During the soaking process, the stirring shaft group, the first gear group and the rotating motor drive the recycled plastic to rotate and clean, so that the dust and soil on the surface of the recycled plastic are synchronously settled at the bottom of the bucket cover for collection and classification.

[0026] (2) By setting the following in the cleaning and drying components: the spray nozzle, the spray pipe, the branch pipe and the compression fan, the problem that the first control valve needs to be controlled to open after the recycled plastic is washed, causing the washing water, the recycled plastic and the washed sediment to fall together, which not only causes confusion but also makes it impossible to separate the washed recycled plastic and the label paper. When the recycled plastic is washed, the operator controls the compression fan to transport the gas inside the bucket cover to the spray pipe and the spray nozzle during operation. The gas entering the spray nozzle blows the recycled plastic floating above the washing water to the inside of the conveying pipe for further processing. The following in the spray nozzle, the spray pipe, the branch pipe and the compression fan can not only save water resources but also utilize the hot water resources for multiple cycles.

[0027] (3) The cleaning and drying components are provided with: branch pipes, compression fans, matching grooves, concave plates, through-hole matching plates, drying cylinders, conveying pipes, spraying pipes and spraying heads, so as to solve the problem of residual water stains on the surface of the recycled plastic after cleaning. When the recycled plastic after cleaning is conveyed on the conveyor belt, the compression fan works to convey the gas into the drying cylinder through the branch pipe. The gas entering the drying cylinder absorbs the water vapor contained in the gas, so that the dry gas is sprayed out through the spraying pipe and the spraying head. When the dry gas is sprayed out, it blows and dries the recycled plastic after cleaning;

[0028] (4) The above situation is solved by the classification and collection component set in the cleaning classification and drying structure. When the bottle flakes and the label paper are deposited together at the bottom of the bucket cover, the bottle flakes push the adjustment plate to move. During the force movement of the adjustment plate, the bottle flakes and the label paper enter the through-hole frame for collection. When the bottle flakes and the label paper enter the through-hole frame for collection, they are prevented from being discharged together with the recycled plastics for re-sorting.

[0029] (5) By setting up the conveying structure, the problem of some water inside the recycled plastic after cleaning, which affects the subsequent recycling of the recycled plastic, is solved. When the recycled plastic is blown into the installation tube, the connecting roller drives the thorn rod to make the recycled plastic and the cutting knife move relative to each other. When the thorn rod and the cutting knife come into contact with the recycled plastic, not only the recycled plastic is cut and separated, but also the excess cleaning water inside the recycled plastic is effectively avoided.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-7 The present invention provides a technical solution: a recycled plastic sorting device with a classification and drying cleaning structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a cleaning, sorting and drying structure 1 fixedly installed on the conveying structure 2, the cleaning, sorting and drying structure 1 includes a cleaning and drying component 101 fixedly installed on the sorting and collecting component 102, and the cleaning and drying component 101 includes a conveyor belt 1011 as a basic body, and a bucket cover 1012 with a through groove on the rear side is fixed on the conveyor belt 1011, wherein the bucket cover 1012 with an inlet and outlet is installed and set, and the bucket cover 1012 with an inlet and outlet is installed and set to effectively facilitate the transportation of the water receiving tray to the inside of the bucket cover 1012 to receive the cleaning water, and a collection vehicle is arranged on one side of the conveyor belt 1011, and the recycled plastics after cleaning and drying are collected and transported by the arranged collection vehicle.

[0040] The above scheme is further characterized in that a heating tube 1013 is embedded in the inner side of the bucket cover 1012, and a stirring shaft group 1014 is rotatably installed inside the bucket cover 1012, and the stirring shaft groups 1014 are meshingly connected via a first gear group 1015, wherein a temperature sensing module is arranged inside the bucket cover 1012, and the heating temperature of the cleaning water is controlled by the arranged temperature sensing module to avoid excessive heating of the cleaning water, which may cause excessive air pressure inside the bucket cover 1012 and cause a dangerous situation.

[0041] Furthermore, in the above scheme, one end of the stirring shaft assembly 1014 passes through the bucket cover 1012 and extends to the outer wall of the bucket cover 1012 to be installed and connected to the rotating motor 1016, and a driving gear 1017 is fixed to the output end of the rotating motor 1016. At the same time, the driving gear 1017 is meshed and connected with the parts of the conveying structure 2 through a chain 1018.

[0042] Furthermore, in the above scheme, a spray pipe 10110 with a spray nozzle 1019 is fixed at the lower part of the bucket cover 1012, and the spray pipe 10110 is installed and connected to one end of a branch pipe 10111 with an internal control valve through a connecting pipe, and the other end of the branch pipe 10111 is installed and connected to the exhaust pipe 10113 through a compression fan 10112.

[0043] The above scheme further has a recessed plate 10114 with a matching groove 10115 embedded and fixed at the other end of the branch pipe 10111, and the recessed plate 10114 is installed and connected to the drying cylinder 10117 via the through-hole matching plate 10116, and the other end of the drying cylinder 10117 is also installed and connected to one end of the conveying pipe 10118 via the recessed plate 10114 and the through-hole matching plate 10116, wherein the matching groove 10115, the recessed plate 10114 and the through-hole matching plate 10116 are arranged to facilitate the rapid installation and disassembly of the drying cylinder 10117, and the arranged drying cylinder 10117 is utilized to effectively adsorb and dry the water vapor contained in the gas, thereby preventing the recycled plastic from being unable to be dried when the gas with excessively high humidity is blown into the interior of the recycled plastic.

[0044] Furthermore, the other end of the delivery pipe 10118 passes through the bucket cover 1012 and extends inside the bucket cover 1012 to be installed and connected to the spray pipe 10119, and a spray head 10120 is embedded in the bottom of the spray pipe 10119. The first control valves 10121 are fixed on the upper and lower sides of the bucket cover 1012, wherein three first control valves 10121 are provided. The three first control valves 10121 are utilized to effectively control the opening and closing of the upper and lower parts of the bucket cover 1012 and the inside of the installation pipe 201.

[0045] In the above scheme, when the recycled plastic needs to be cleaned and sorted, the operator puts the recycled plastic into the bucket cover 1012 and then closes the first control valve 10121. At this time, the heating tube 1013 and the rotating motor 1016 are controlled to work. During the operation of the rotating motor 1016, the stirring shaft group 1014 and the first gear group 1015 are driven to rotate and adjust relative to each other. The recycled plastic is rotated and cleaned when the stirring shaft group 1014 is relatively rotated and adjusted.

[0048] In the above scheme, when the bottle flakes push the adjustment plate 1025 to move, the adjustment plate 1025 is subjected to force movement. At this time, the bottle flakes and the label paper are collected in the through-hole frame 1023 together. When the bottle flakes and the label paper are collected inside the through-hole frame 1023, the bottle flakes and the label paper are prevented from being discharged together with the recycled plastic for re-sorting. When all the recycled plastics are cleaned, the operator opens the first control valve 10121 to pull the through-hole frame 1023 and the port plate 1021 to separate by force, which makes it convenient for the operator to clean the bottle flakes and the label paper.

[0051] In the above scheme, when the recycled plastic is blown into the installation tube 201, the connecting roller 203 drives the thorn rod 204 to make the recycled plastic and the cutting knife 207 move relative to each other. When the thorn rod 204 and the cutting knife 207 come into contact with the recycled plastic, not only the recycled plastic is cut and separated, but also the excess cleaning water inside the recycled plastic is effectively avoided.
