TECHNICAL FIELD
[0001] The utility model relates to material sorting field especially involves the buoyancy sorting machine for polyester bottle piece sorting. BACKGROUND
[0002] In the polyester bottle piece recycling industry, high-quality sorting is a crucial link. With the enhancement of environmental awareness and the growth of resource recycling demand, the technology for polyester bottle piece sorting has been widely concerned. Among them, the buoyancy sorting machine as a kind of key sorting equipment plays an important role in the polyester bottle piece recycling process. It is based on the difference in density between polyester bottle piece and impurities, and the separation of the two is realized by using sorting fluid of specific density, so as to provide higher-purity polyester bottle piece raw materials for subsequent processing and utilization.
[0003] The traditional polyester bottle piece sorting mechanical structure mainly includes simple sorting tank and basic feeding and discharging device. In terms of technical principle, the mixture of polyester bottle piece and impurities is directly put into the sorting tank filled with sorting fluid. The sorting fluid has a certain density, and in the absence of other auxiliary measures, only the gravity and buoyancy of the material itself are relied on to naturally settle or float in the sorting tank. Then the floating material (such as some light impurities) and the sinking material (such as polyester bottle piece and heavier impurities) are collected through the discharge port arranged at different heights.
[0004] However, this traditional sorting method has a serious problem, that is, impurities are easily accumulated inside the sorting machine. In the long-term sorting process, impurities will continue to accumulate inside the sorting machine, which not only affects the normal operation of the sorting machine, such as causing internal pipeline blockage and affecting the normal flow of sorting fluid, but also reduces the sorting effect, because the accumulation of impurities may change the stability of the sorting environment inside the sorting machine, thereby affecting the effective separation between polyester bottle piece and impurities.

[0034] The polyester bottle pieces are poured into the inside of the screening box 5 from the feeding pipe 6, and then the motor 15 is started to rotate the rotating shaft 13, which is a key component for power transmission, to transmit the rotating motion of the motor 15 to the eccentric wheel 14, and the rotation of the rotating shaft 13 drives the eccentric wheel 14 to rotate. Due to the eccentric structure design, when it rotates with the rotating shaft 13, it will produce a periodic up-down displacement change, which is the direct reason for the subsequent screening plate 7 to shake. The rotation of the eccentric wheel 14 drives the screening plate 7 to shake, and the screening plate 7 is the core component for screening impurities. The shaking of the screening plate 7 can make the polyester bottle pieces jump and roll on the plate.

Through the adsorption of the activated carbon adsorption plate 19, the purity of the sorting liquid can be significantly improved, and the sorting performance of the sorting liquid can be ensured when it is recycled.
