Solid and liquid separator

Abstract

A trash extractor relates to a solid-liquid separation machine which includes a box body, a water inlet communicated with the box body, a water outlet, an overfall gap, a screen stencil and a slag discharge hole; the box body is barrel-shaped and transversely arranged; the box body is internally provided with a main shaft and is externally provided with a drive device which is connected with the main shaft that is provided with at least one pair of sieve trays; the screen stencil is fixedly connected on the sieve trays; a friction guide arc partition is arranged at the lower part of the box body, and the sides of the sieve trays are provided with O-ring seals which are contacted with the friction guide arc partition; the water inlet is communicated with a cavity between the pair of sieve trays; a scouring mechanism of the screen stencil. The trash extractor has the advantages of compact structure, low energy consumption, little noise and high treating efficiency, and solves the water precipitating and decanting processing mode used for the small sized solid state substance in the waster water for a long time.

Description

technical field [0001] The invention relates to a solid-liquid separation machine, in particular to a separator for separating fibrous and flake solid impurities in industrial wastewater treatment. Background technique [0002] At present, in the process of waste and sewage treatment, devices such as window-shaped fixed grids placed in the canal are generally used to intercept suspended and floating solid debris in waste and sewage. The disadvantage of this method is that it is difficult to remove them. or fibrous debris. A small amount of smaller debris can only be intercepted through the attachment and entanglement between large-sized debris and small-sized debris. In addition, if there are many solids in the wastewater, blockage and obstruction will occur in a short period of time, and slag removal equipment is required, resulting in a loose structure, large volume, and a large footprint of the entire device, which will increase the cost and consume more energy. higher....

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem that the fibrous and small-sized sheet-like solid impurities in the wastewater are difficult to deal with in the prior art, the invention provides a device installed in series in the sewage pipeline, which can reliably intercept and separate the suspended and floating impurities in the wastewater. dandruff separator that can self-clean and discharge slag during continuous operation
