Unpowered whirling cylinder sand and sludge removing machine

Abstract

The invention relates to an unpowered whirling cylinder sand and sludge removing machine. The machine comprises a treatment cylinder, a slurry input pipe, a reject output pipe, a compressed gas conduit, a reject storage vessel and a gas pump, wherein a vortex filter separator is arranged on the inner wall of the upper section of the treatment cylinder; a coarse reject collecting tank is arranged in the treatment cylinder under the vortex filter separator; the output end of the slurry input pipe feeds slurry water to a water inlet of the vortex filter separator; a reject output pipe is arranged at the bottom of the coarse reject collecting tank; the discharge end of the reject output pipe extends into the reject storage vessel; and the input end of the compressed gas conduit is connected with the gas pump, and the output end of the compressed gas conduit is inserted into the output section of the reject output pipe. The machine saves energy, and ensures that the sewage automatically rotates, whirls and accelerates; the sewage whirling forms vortex speed difference, which is convenient to deposit sand and eliminate external interference, and has high sand depositing efficiency; and the machine also improves the outflow speed of the sewage so as to realize the function of sand and water separation.

Description

technical field [0001] The invention relates to sewage and sludge treatment equipment, in particular to a non-powered swirl tube desand and sludge remover. Background technique [0002] In the domestic sewage and industrial wastewater, the sewage collected by various channels is involved in a large amount of mud and sand, which brings great resistance and difficulty to the circulation of sewage and the process of sewage treatment. A very important part of the initial stage. [0003] The main purpose of sand settling and sand removal is to use the simplest means and the most economical method to achieve the effect of sand settling and sand removal as much as possible, so that the sewage with reduced sand content can enter the various processes of sewage treatment smoothly, so as to ensure that the process of sewage treatment The smooth progress of the process, thereby improving the quality of sewage treatment. [0004] At present, the sedimentation tank and cyclone desandin...

AI Technical Summary

Problems solved by technology

[0004] At present, the sedimentation tank and cyclone desanding machine (cyclone separator) commonly used in China, and the general cyclone desander (cyclone separator) have the disadvantages of power consumption and low sedimentation rate.
