[0015] The present invention provides a textile wastewater treatment and recovery device, which has the following beneficial effects:

[0016] (1) The present invention, through the setting of the filtering device, allows sewage to be injected into the A box through the water inlet, and the screen machine is driven to work by the rotating motor in conjunction with the conveying roller. The screen machine conveys the solid matter in the sewage to the waste outlet, and the conveying roller rotates in conjunction with the belt to drive the blade to rotate, thereby achieving the crushing treatment of impurities. If these impurities enter the treatment equipment without being crushed, they will increase the load of the equipment and reduce the treatment efficiency. Through the crushing treatment, large-sized impurities can be decomposed into smaller particles, which helps to improve the efficiency of subsequent treatment equipment.

[0017] (2) The present invention, through the setting of the cleaning device, at this time, impurities and debris will be stained on the blade, and water will be injected into the air inlet cylinder through the water tank and the water pipe, and then the water in the air cylinder will be sprayed out from the nozzle through the transmission roller and the touch rod to contact the extrusion block, thereby cleaning the blade and improving the working efficiency of the blade. The transmission roller cooperates with the touch rod to contact the push rod so that the arc rod drives the impact block to hit the screen machine, so that the impurities in the screen machine are shaken off, preventing the subsequent sewage treatment from being blocked or worn by solid particles, extending the service life of the equipment, and reducing maintenance and repair costs.

[0018] (3) The present invention, through the setting of the dosing device, puts the medicine into the medicine box, and then the water level in the B box rises to drive the float rod to rise, and the rise of the float rod causes the slide to fall. At this time, the medicine is transported to the medicine box through the pipeline with gravity, and then the rotating point machine rotates in conjunction with the rotation of the rotating rod, the stirring rod, the medicine box and the eccentric block, so that the vibration generated by the rotation of the eccentric block in the medicine box is better processed to be fine, thereby improving the dissolution rate of the medicine and sewage. The rotation of the rotating rod is coordinated with the horizontal gear and the rotating shaft to drive the small gear to rotate. The rotation of the small gear causes the scraper A and the scraper B to move toward the center of the B box, thereby stirring the bottom sediment, helping to prevent agglomeration and blockage of pipes or equipment, which can maintain the normal operation of the system and reduce maintenance requirements.
