Technical Field
[0001] This invention relates to the field of dehydration equipment technology, and more specifically, to a surface dehydration device for recycled polyester bottle flakes after cleaning. Background Technology
[0002] Recycled polyester (PET) bottle flakes are recycled materials made from waste PET plastic bottles through processes such as sorting, crushing, and washing. They are widely used in textiles, packaging, and automotive parts, and therefore require improvement. After washing, recycled PET bottle flakes generally need to be dehydrated to facilitate subsequent reprocessing. However, in existing recycled PET bottle flakes, the discharge hopper direction after dehydration is fixed. Some discharge upwards, while others discharge from the side. This is mainly determined by the hardness of the recycled PET bottle flakes and the method of material collection. Currently, the discharge hopper direction of each dehydration device is fixed and cannot be adjusted, making it unsuitable for various scenarios and thus requiring improvement.

Detailed Implementation
[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] This invention provides a technical solution: Please refer to the following: A surface dehydration device for recycled polyester bottle flakes after washing. Figures 1-8 The machine includes a housing 10, and discharge hopper 50 and feed hopper 40 connected to the inside of the housing 10 are respectively provided on the left and right sides of the housing 10. The left and right sides of the housing 10 are respectively provided with a left opening and a right opening, both of which are circular. The feed hopper 40 is located at the right opening, and the discharge hopper 50 is located at the left opening. The feed hopper 40 is fixedly installed to the right side of the housing 10 by bolts.
[0025] Inside the housing 10, a feeding shaft 60 is rotatably provided along its length. The feeding shaft 60 is horizontally positioned, and multiple feeding blades 61 are fixedly installed on the shaft body of the feeding shaft 60. The feeding shaft 60 located inside the feed hopper 40 is also provided with feeding blades 61. In this way, when recycled polyester bottle flakes are added into the feed hopper 40, they are easily conveyed into the housing 10 under the action of the feeding blades 61. They are then conveyed into the discharge hopper 50 and finally ejected from the discharge hopper 50.
[0026] A partition 20 is installed in the middle of the inner wall of the housing 10. A detachable screen assembly 30 is provided on both sides of the partition 20. The feeding blade 61 is located inside the screen assembly 30. The screen assembly 30 includes two semi-circular screens 300. Mounting ears 301 are fixed at both ends of the semi-circular screens 300. The mounting ears 301 are provided with multiple mounting holes. The two semi-circular screens 300 are connected by bolts and nuts.
[0027] The partition 20 has a circular hole in the middle, and a second protruding ring 21 is fixedly connected to both sides of the partition 20 at the circular hole. The inner walls of the left and right sides of the housing 10 are also fixed with the second protruding ring 21 at the left and right openings. The inner diameter of the two semicircular screens 300 after installation is equal to the outer diameter of the second protruding ring 21. The distance from the inner walls of the left and right sides of the housing 10 to the inner walls of the left and right sides of the partition 20 is equal, and this distance is slightly greater than (almost equal to) the length of the semicircular screen 300. This allows the semicircular screen 300 to be installed against the second protruding ring 21 and also facilitates the disassembly of the semicircular screen 300. It avoids frictional resistance between the end of the semicircular screen 300 and the inner walls of the left and right sides of the housing 10 or the partition 20, which would affect the disassembly of the semicircular screen 300.
[0028] This application provides a partition 20, and screen components 30 are provided on both sides of the partition 20, which can form multiple semi-circular screens 300. Compared with the traditional two large half-screens, when the screen is damaged, it is not necessary to replace the entire screen, but only a part needs to be replaced. Furthermore, the multiple small semi-circular screens 300 are relatively lighter and easier to replace.
[0029] When recycled polyester flakes enter the machine housing 10, the water will be removed by centrifugal force during rotation, and the water will pass through the semi-circular screen 300.
[0030] It is worth noting that the interior of the housing 10 is hollow, and the bottom wall of the housing 10 extends downward to form a drainage groove 100. The side wall of the housing 10 is provided with a drainage hole 101 that communicates with the drainage groove 100. The front and rear sides of the housing 10 are provided with openings, and a detachable (can be bolted) door 11 is installed at the opening. After the door 11 is removed, it is convenient to replace the semi-circular screen 300 inside.
[0031] The discharge hopper 50 includes a circular shell 500 and a discharge hopper 501 communicating with the interior of the circular shell 500; one end of the feeding shaft 60 extends into the circular shell 500 and is rotatably connected to the inner wall of the circular shell 500 through a bearing; multiple throwing plates 62 are fixedly connected to the shaft of the feeding shaft 60 located inside the circular shell 500; the dehydrated recycled polyester bottle flakes can be thrown to the discharge hopper 501 for discharge through the throwing plates 62.
[0032] The other end of the feeding shaft 60 passes through the feeding bin 40 and extends to the outside of the feeding bin 40. The feeding shaft 60 and the feeding bin 40 are rotatably connected by bearings. It also includes a drive mechanism for driving the feeding shaft 60 to rotate.
[0033] Specifically, the drive mechanism includes a motor 70, a first pulley 71, a second pulley 72, and a belt 73. The first pulley 71 is mounted on the output shaft of the motor 70, the second pulley 72 is mounted on the other end of the feeding shaft 60, and the belt 73 is sleeved on the first pulley 71 and the second pulley 72.
[0034] When the motor 70 is started, it will drive the first pulley 71 to rotate, which in turn will drive the second pulley 72 and the feeding shaft 60 to rotate via the belt 73. This will enable the feeding blades 61 and the throwing plate 62 to rotate, thus achieving feeding, dewatering and discharging.
[0035] A base 80 is fixedly installed on the bottom wall of the housing 10. A mounting seat 74 is bolted to the side of the base 80 near the motor 70. The motor 70 is bolted to the mounting seat 74.
[0036] This application also includes a rotation adjustment component, which is used to adjust the rotation of the circular shell 500 to change the orientation of the discharge hopper 501, thereby adapting to the adjustment of the discharge direction of the material when different collection needs are met; while the existing discharge hoppers have a fixed orientation, and the dewatering equipment corresponds to a fixed discharge direction every day.
[0037] The rotation adjustment assembly includes a connecting ring 502 and a first convex ring 102. The first convex ring 102 is fixedly connected to the left opening of the housing 10. One side of the connecting ring 502 is sleeved on the circular shell 500 and fixedly connected to the circular shell 500. The other side of the connecting ring 502 is sleeved on the first convex ring 102 and rotatably connected to the first convex ring 102.
[0038] The connecting ring 502 has two strip grooves 503 on its ring wall. Four threaded posts 103 are fixedly connected to the outer wall of the first convex ring 102. Two threaded posts 103 are placed in one strip groove 503 and the other two threaded posts 103 are placed in another strip groove 503. It also includes a locking nut that matches the threaded posts 103. By loosening the locking nut, the connecting ring 502 can be rotated, thereby adjusting the orientation of the discharge hopper 501 to meet the needs of actual use. After tightening the locking nut, the connecting ring 502 can be fixed.
