Anti-winding sewage treatment device

Abstract

The invention relates to the technical field of wastewater treatment equipment, and discloses an anti-winding sewage treatment device which comprises a treatment box, water outlets are formed in the left side and the right side of the treatment box correspondingly, screens are fixedly installed in the two water outlets, water flowing grooves are fixedly connected to the outer sides of the two water outlets correspondingly, and the two water flowing grooves respectively communicate with the two water outlets. According to the anti-winding sewage treatment device, when rotating rods rotate, the rotating rods on the two sides collide with blocking rods, sleeves on the two sides move along the rotating rods under the action of impact force, then winding objects wound around the surfaces of the rotating rods can be scraped off, meanwhile, the sleeves on the two sides move to extrude elastic rods, and under the action of extrusion force, the elastic rod expands towards the outer side, so that outward pulling force can be applied to the entanglements wound on the rotating rod, and the effect of treating the entanglements on the surface of the rotating rod can be enhanced.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to an anti-winding sewage treatment device. Background technique [0002] In the process of production and life, a lot of domestic sewage and domestic garbage will be produced. During sewage treatment, activated sludge should be used to treat the concentrated sewage. During the treatment process, the sewage contains a large amount of flexible and difficult to degrade substances. For example, plastic bags, the existence of these substances will not only affect the full mixing of sewage and activated sludge, but also entangle on the surface of the mixing device and affect the normal use of the mixing device. The surface of the mixing device is entangled with a large amount of plastic waste, plastic waste Dragging the mixing device around the sewage will increase the load of the mixing device, thereby increasing the power consumption, and if the plastic waste is ...

[0002] In the process of production and life, a lot of domestic sewage and domestic garbage will be produced. During sewage treatment, activated sludge should be used to treat the concentrated sewage. During the treatment process, the sewage contains a large amount of flexible and difficult to degrade substances. For example, plastic bags, the existence of these substances will not only affect the full mixing of sewage and activated sludge, but also entangle on the surface of the mixing device and affect the normal use of the mixing device. The surface of the mixing device is entangled with a large amount of plastic waste, plastic waste Dragging the mixing device around the sewage will increase the load of the mixing device, thereby increasing the power consumption, and if the plastic waste is entangled and tied tightly to the mixing device during the rotation, it will be very difficult to clean up, and more and more will be tied up , it is easy to accumulate relatively stable sewage inside plastic waste, and it is difficult for sludge to fully mix with sewage, which affects the efficiency of sewage treatment. When general domestic sewage treatment devices promote the mixing of activated sludge and sewage, it is easy to mix flexible plastic waste Winding on the rotating structure not only increases the consumption of electric energy, affects the efficiency of sewage treatment, but also increases the difficulty of cleaning, so a kind of anti-winding domestic sewage treatment device is needed
