[0002] Printing and dyeing, also known as dyeing and finishing, is a processing method, and is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. The treatment of printing and dyeing wastewater is a complex process aimed at reducing pollution to the environment and ensuring the reuse of water resources. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the difficult-to-treat industrial wastewaters. The wastewater contains dyes, slurries, additives, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc.

[0003] The existing printing and dyeing wastewater treatment basically adopts the method of chemical input to solve the printing and dyeing wastewater to meet the discharge standards. Chemical treatment is to use chemical agents to react chemically with pollutants in wastewater to achieve the purpose of removing pollutants. Common chemical treatment methods include precipitation, oxidation, reduction, etc. The precipitation method is to precipitate pollutants such as dyes and additives in wastewater by adding chemical precipitants, the oxidation method is to use chemical oxidants to oxidize and decompose organic dyes, and the reduction method is to reduce dyes to harmless substances by reducing agents. The chemical treatment method has low cost, high efficiency and good effect, but at this stage, the solid and liquid are not easy to separate under long-term treatment, the precipitate is not easy to remove, and it is easy to produce adhesion and clogging, which reduces its treatment efficiency and is not conducive to the treatment and reuse of printing and dyeing wastewater; therefore, how to design a convenient and clean printing and dyeing wastewater treatment and reuse system is particularly important; in view of this, we propose a wastewater treatment and reuse system based on clean printing and dyeing.

[0016] 3. The present invention connects a slider by sliding on the slide.

The present invention opens a curved groove 6084 on the outer surface of the rod body 6081. Since a limit rod 609 is inserted into the curved groove 6084, when the rod body 6081 moves, the rod body 6081 rotates. The rotation of the rod body 6081 drives the drill bit 6083 to produce a better dredging effect on the end of the screw barrel 503. The spring 6082 resets the rod body 6081. The present invention has a good cleaning effect and a high cleaning efficiency. It solves the problem that the sewage treatment and reuse system is prone to blockage to a great extent, which is conducive to the rapid development of the industry.

A servo motor 3062 is arranged on the mounting frame 3061. The servo motor 3062 drives the rotating block 3063 to rotate. The rotating block 3063 drives the connecting rod 3064 to rotate. The connecting rod 3064 drives the connecting shaft 3065 to rotate. The connecting shaft 3065 rotates to pull the transmission belt 3066 to rotate. The transmission belt 3066 drives the sliding assembly 308 to slide on the slide 3067. The sliding connection slider 3082 on the slide 3067 slides. When the transmission belt 3066 drives the connecting shaft 3065 to rotate, the connecting shaft 3065 drives the driving rod 3081 to make the slider 3082 slide on the slide 3067. The slider 3082 drives the gear at the top thereof. 3084 rotates, and the different gear 3084 is meshed and connected to the gear 3083. When the slider 3082 slides on the slide 3067, the shift rod 3085 on the different gear 3084 rotates due to the obstruction of the limit block 3086. The different gear 3084 drives the gear 3083 to rotate, so that the gear 3083 drives the scraper 307 to rotate. A curved groove 6084 is opened on the outer surface of the rod body 6081. Since a limit rod 609 is inserted in the curved groove 6084, when the rod body 6081 moves, the rod body 6081 will rotate. The rotation of the rod body 6081 drives the drill bit 6083 to produce a better dredging effect on the end of the screw barrel 503.
