Embodiment Construction
[0013] The present invention as Figure 1-3 As shown, it includes a swirl grit chamber. The swirl grit chamber includes a tank body 9, a driving device 2, an impeller 3 and a sand discharge pipe 1. The upper side wall of the tank body 9 is provided with an inlet along the tangential direction. A water outlet 11 is provided in the middle of the water outlet 10 and the upper side wall, the bottom of the pool body 9 is a sand settling bucket, the upper part of the sand discharge pipe 1 extends out of the pool body 9, and the lower part is located in the sand settling bucket; Among them, the driving device 2 (ie, the motor) drives the impeller 3 to move, so that the stirring action occurs in the pool body;
[0014] Such as image 3 As shown, it also includes a sand cover 8 and a conical bucket 6. The conical bucket 6 is in the shape of a bucket with a small top and a large bottom. The conical bucket 6 is arranged at the bottom of the sand discharge pipe 1. The conical bucket The...

The present invention discloses a vortex sand-water separator and provides the vortex sand-water separator which is simple in structure and avoids clogging of sand discharge pipes. The vortex sand-water separator includes a grit chamber. The grit chamber includes a chamber body, a driving device, a blade wheel and a sand discharge pipe. A water inlet is arranged on the upper side wall of the chamber body via a tangential direction, a water outlet is arranged at the middle of the upper sidewall, a grit hopper is arranged at the bottom of the chamber body, and an upper part of the sand discharge pipe stretches out from the chamber body and an lower part of the sand discharge pipe is located within the grit hopper. The vortex sand-water separator also includes a sand cover and a tapered hopper. The tapered hopper presents a hopper shape which is small at the top and large at the bottom and arranged at the bottom of the sand discharge tube, and a deflector rod is arranged within the conical hopper. The sand cover is arranged on the sand discharge pipe and the conical hopper is coated in the sand cover. The sand cover and the conical hopper are arranged at the lower part of the sand discharge pipe. The sand cover can filter sand grains at work to avoid large volumes of sand grains clogging the sand discharge pipe. Then the tapered hopper gathers the sand into the sand discharge pipe to discharge the sand and improves the reliability of the sand discharge.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a cyclone sand-water separator. Background technique [0002] The cyclone sand water separator is the equipment used to separate and extract sand from sewage in the sewage treatment plant, including the cyclone grit chamber. The swirl grit chamber in the prior art is usually provided with a grit discharge pipe for lifting the bottom of the swirl grit chamber. The upper end of the sand discharge pipe is connected to the sump of the sand-water separator through a pipe, and the lower end extends to the bottom of the swirling grit chamber. However, during work, the sand discharge pipe is often clogged, and frequent manual cleaning is required, which not only increases labor costs, but also affects the normal use of the sand-water separator and reduces the separation efficiency of sand and water. Contents of the invention [0003] Aiming at the above problems, the present invention...
