Description

Technical Field

[0001] The utility model relates to the technical field of sand-water separators, in particular to a sand-water separator with controllable water flow velocity. Background Art

[0002] Sand-water separator is a common sewage pretreatment equipment. At present, in the treatment process of sewage treatment plants, solid particles and sand and gravel in sewage need to be separated during sewage pretreatment.

[0003] According to a publicly disclosed sand-water separator (Announcement No.: CN217511305U), in the above application, during the process of liquid entering the water inlet pipe, sand and gravel are very easy to stick to the inner wall of the feed pipe, causing the feed pipe to be blocked. The blocked feed pipe will not be able to separate, and the aperture size of the water inlet pipe is fixed, so the flow rate cannot be adjusted according to the actual sand-water mixture characteristics and processing requirements. When the sand-water ratio changes greatly or the properties of the sand particles are different, the fixed aperture cannot optimize the separation effect. At the same time, when the actual processing volume is small, the fixed large aperture may cause the flow rate to be too fast, increase unnecessary energy consumption, and may also affect the separation effect. To address this problem, we proposed a sand-water separator with controllable water flow rate. Utility Model Content

The gear is driven by the force to drive the rotating rod and the turntable to rotate. When the turntable rotates, the movable rod hinged on the surface of the turntable can continuously knock on the surface of the liquid inlet pipe, and the sand and gravel stuck to the inner wall of the liquid inlet pipe can be affected by the vibration force and fall into the device body for filtration and recovery. This method can avoid clogging of the liquid inlet pipe and affect the separation effect of the sand-water separator.

[0017] 2. The sand-water separator with controllable water flow rate is provided with a driven component. A circular plate is rotated on the surface of a fixed frame. The circular plate drives the threaded rod to rotate in the fixed frame. The slide plate is forced to slide in the flat hole. The vertical rod fixed on the surface of the slide plate moves synchronously in the device body. The flat rod fixed on the surface of the vertical rod is forced to move in the device body under the support of spring 2. When the fixed plate fixed on the surface of the flat rod slides at the bottom of the liquid inlet pipe, the circular hole or branch hole opened on the surface of the fixed plate will gradually overlap with the bottom of the liquid inlet pipe. Since the apertures of the circular hole and the branch hole are different, the water flow rate can be adjusted to achieve different sand-water mixture characteristics and treatment requirements.
