Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a device for treating sewage in construction waste. Background Art

[0002] A large amount of water is used in the construction process, and part of the construction waste will be discharged as wastewater. The construction wastewater needs to be treated when it is discharged, so corresponding sewage treatment equipment is needed.

[0003] For example, a Chinese patent with publication number "CN213569848U" discloses "a device for treating sewage in construction waste", whose main structure includes a base, a crushing box fixedly installed on the surface of the base, a speed brake fixedly installed inside the crushing box, and a garbage inlet fixedly installed on the outside of the crushing box. The device for treating sewage in construction waste, by setting up a vibration block, a screen and a collection box, uses the vibration of the vibration block to drive the screen to vibrate, so that the construction waste falling on the surface of the screen is screened, and the larger garbage that has not been completely crushed is collected, and the collected larger garbage is put into the crushing box from the garbage inlet again for crushing, which effectively solves the problem of incomplete crushing of construction waste. By setting up a filter screen plate, it can effectively remove particulate impurities in construction sewage, and the impurity removal effect is significant, preventing particles from clogging the filter holes of the filter device and affecting the filtering effect, making the sewage filtering effect more stable.

The No. 1 threaded structure 44 includes an internal threaded structure arranged inside the No. 1 internal threaded cavity 42 and an external threaded structure arranged on the rod body of the No. 1 externally threaded rod 46.

The sewage enters the sewage cavity 22 through a plurality of No. 1 liquid flow holes 24, and the impact of the water flow acts on the end face of the rotating impeller 211, thereby driving the rotating impeller 211 and the No. 1 rotating shaft 210 to rotate, and the No. 1 rotating shaft 210 drives the No. 2 rotating shaft 313 to rotate, and then drives the spiral blade 314 to rotate, and the flocculant enters the conical flocculant under the action of gravity. In the drainage chamber 38 and the flocculant delivery hole 37, driven by the spiral blade 314, the downward flow is accelerated, and finally discharged into the sewage flushing cavity 22 through the liquid flow chamber 36 and the No. 3 liquid flow hole 39. The speed of rotation of the spiral blade 314 will directly affect the speed of flocculant delivery, and then affect the mixing ratio of sewage and flocculant. The sewage and flocculant will enter the liquid discharge cylinder 26 from the sewage flushing cavity 22, and generate turbulence through the spiral guide plate 29, so that the sewage and flocculant are mixed, and finally discharged into the sedimentation tank through the discharge port of the liquid discharge cylinder 26.
