River water sediment filtering and collecting device

Abstract

The invention discloses a river water sediment filtering and collecting device, which comprises a primary sedimentation tank, wherein sludge water to-be-treated is introduced into the primary sedimentation tank; a sludge pump, wherein an inlet of the sludge pump is communicated with the bottom of the primary sedimentation tank; a mixer, wherein an outlet of the sludge pump is communicated with aninlet of the mixer; a first filter belt machine, wherein an inlet of the first filter belt machine is positioned below an outlet of the mixer; a hydraulic machine; a second filter belt machine locatedbelow the hydraulic machine, and the inlet end of the second filter belt machine slides to be communicated with the outlet end of the first filter belt machine; and a conveyer belt positioned at therear end of the second filter belt machine. By adopting the treatment process disclosed by the invention, the equipment manufacturing cost is only about 1 / 2 of the original equipment manufacturing cost, the process is simple, and the moisture content of the produced sludge is reduced to 50-60%.

Description

Technical field [0001] The present invention is specifically related to a river water precipitate filtration collection device. Background technique [0002] Since the power consumption of the power plant is very large, in order to reduce production costs, companies often choose to use river water, but the river water contains a large number of sediments and impurities, it is necessary to treat river water before use, the first step is to clarify, then clarify In the pool, it will contain a large amount of sediment and impurities that need to be emissively, but due to the clarification of the tank drain, the content of the silt is high, according to the environmental protection requirements, it is impossible to directly discharge into the environment and tube, it needs to be treated; the mainstream process is "Concentrate pool + sleeve centrifuge" and "concentrated pool + plate filter press", these two process costs, and the water-containing mild water content is as high as 80-90...

AI Technical Summary

Problems solved by technology

[0002] Due to the large water consumption of power plants, in order to reduce production costs, enterprises often choose to use river water, but the river water contains a lot of sediment and impurities, and the river water needs to be treated before use. The first step is clarification, then clarification after clarification The silt water containing a large amount of sediment and impurities needs to be discharged in the tank, but due to the high content of silt in the discharge water from the clarifier tank, it cannot be directly discharged into the environment and pipes according to environmental protection requirements, and needs to be treated; the current mainstream process is "Concentration tank + decanter centrifuge" and "concentration tank + plate and frame filter press", these two processes are expensive, and the moisture content of the treated sludge is as high as 80-90%
