Using the filter auxiliary agent separated by backwashing from a filter element repeatedly and effectively, the consumption amount of a filter auxiliary agent and the generation of industrial waste can be suppressed. In a filter auxiliary agent pre-coat circuit, a filter auxiliary agent in a pre-coat tank is attached and stacked on a filter element in a filter case, and a filter auxiliary agent layer is formed. In a filter circuit, the filter auxiliary agent layer of the filter element removes sludge in the filter treatment liquid in a main tank. A backwashing circuit breaks down the filter auxiliary agent layer and a sludge layer, separates the filter auxiliary agent layer and the sludge layer by backwashing from the filter element, and circulates to the pre-coat tank. After repeating these steps a plurality of times, the filter auxiliary agent and sludge separated by backwashing are taken out to the exterior.

The lamp tube external member comprises a hollow fixing sleeve and the lamp tube, wherein the lamp tube is movably arranged in the hollow fixing sleeve, and the front end of the hollow fixing sleeve is in threaded connection with the tail end of the handle pipe. The tail end of the lamp tube abuts against the retractable pressing part, and a lighting lamp at the other end of the lamp tube is limited through the edge at the tail end of the hollow fixing sleeve.

The present invention relates to the field of a cable retracting device using a super-flexible wear-resistant cable for a robot, specifically a cable retracting device for a robot using a super-flexible wear-resistant cable, including a robot hand body, a cable, a retracting mechanism, and a trigger mechanism , shock absorbing mechanism and heat dissipation mechanism; through the cooperation between the cable and the retracting mechanism, the cable can be retracted freely under the movement of the robot body, preventing the cable from being stuck and broken, and at the same time, the cable is accidentally stuck At this time, the trigger mechanism can be used to make the robot body stop working after receiving the instruction, so as to prevent damage to the robot body. During the retraction process, the cable will guide and slow down the cable through the shock absorbing mechanism, so that the cable does not It will be broken or stuck due to pressure or elasticity when moving, causing damage to the robot body. The movement of the cable makes the heat dissipation mechanism work, thereby cooling and blowing other mechanisms inside the robot body, so that the robot body Extended lifespan.
