Abstract

The invention discloses a decontamination and sand removal machine, comprising a cyclone grit chamber and a grid tank; the bottom of the cyclone grit chamber is provided with a central sand hopper, an extended sand tank, a slag separation orifice, an aeration sand washing device, The sand filter tank and the filtered water tank; the sand filter tank is arranged above the filtered water tank, and a filter screen is arranged in it, and the sand filter tank and the filtered water tank are connected; a water lifting device is installed in the filtered water tank, and the water lifting device includes a The outer wall of the water pipe is attached with a water-lifting gas pipe; the top of the water-lifting pipe is provided with a cylindrical water tank; the center of the grit chamber is equipped with a water-elution sand-extracting device, and the water-elution sand-extracting device includes a central sand-lifting pipe, a sand leakage groove, and a large cylinder with an open upper end The large cylinder is connected with the cylindrical water tank; the outer wall of the central sand-lifting pipe is attached with a sand-lifting gas pipe; the sand leakage tank is arranged at the bottom of the large cylinder and communicated with it; The invention provides a cleaning and sand removing machine with more reasonable structure, better cleaning and slag removal effect and lower energy consumption.

Description

technical field [0001] The invention relates to a decontamination and sand removal machine, in particular to a dedusting machine with a daily processing capacity of not less than 5000-10000 cubic meters, which is installed on the water outlet pipeline of a lifting pump after a coarse grille, and is added in one step to finely filter and decontaminate sand with small gaps. , Mechanical equipment for slag separation. Mainly used in water supply and drainage pump stations, urban domestic sewage treatment plants, water plants, and industrial wastewater pretreatment stages for sand removal and pollution blocking and cleaning equipment. It is especially suitable for the pretreatment occasions with more sand behind the coarse grid, more suitable for the pretreatment occasions of the membrane treatment process, and also suitable for the occasions where the expansion of the sewage treatment plant does not increase the civil construction. Background technique [0002] At present, the...
