Then the water pump conveys the water flow to the circulation pipe. Since the circulation pipe is connected to the water inlet pipe, the water flow enters the interior of the cleaning box through the water inlet pipe again, and the waste polyester is cleaned for the second time. Without the need to use additional water resources, the cleaning effect of impurities on the surface of the waste polyester is improved, and water resources can be reasonably used to reduce resource waste, and the presence of pollutants on the surface of the waste polyester can be reduced as much as possible, thereby improving the recycling quality of the waste polyester.

[0008] As a further improvement of the above solution, one end of the circulation pipe is inserted into the inside of the water inlet pipe, and a bracket is fixedly connected to one side of the outer surface of the cleaning box.

[0014] As a further improvement of the above solution, a brush head group is fixedly connected to the lower surface of the brush holder, and a movable block is fixedly connected to the middle of the upper surface of the brush holder.

[0015] Through the above technical solution, the brush head group can scrub the outer surface of the waste polyester, improve the treatment effect of impurities on the surface of the waste polyester, and improve the recycling quality of the waste polyester.

[0016] As a further improvement of the above solution, the internal thread of the movable block is connected to a main screw, and one end of the main screw is fixedly connected to the output end of the servo motor.

[0017] Through the above technical solution, after the servo motor is started, it drives the main screw to rotate along the auxiliary bearing. Since the movable block is threadedly connected to the main screw, when the main screw rotates, it drives the movable block to move, and the movable block thereby drives the brush holder and brush head group at the bottom to move to clean the waste polyester.

[0018] As a further improvement of the above solution, the other end of the main screw is fixedly connected to an auxiliary bearing, one side of the auxiliary bearing is fixedly connected to the inner wall of the cleaning box, and a control panel is provided in the middle of the front end of the cleaning box.

[0019] Through the above technical solution, the control panel can control the opening and closing of the servo motor and the water pump, making it convenient for personnel to make timely adjustments.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a recovery component, and a water pump draws out the water flow after the waste polyester is soaked and cleaned through a suction pipe, and the impurity particles in the water can be filtered through the filter screen inside the suction pipe, and then the water pump conveys the water flow to the circulation pipe. Since the circulation pipe is connected with the water inlet pipe, the water flow enters the interior of the cleaning box again to perform a second cleaning on the waste polyester. In the case of not needing to use additional water resources, the cleaning effect of impurities on the surface of the waste polyester is improved, and water resources are reasonably utilized to reduce the presence of pollutants on the surface of the waste polyester as much as possible, thereby improving the recovery quality of the waste polyester.
