Solid-liquid fast separation device

Abstract

The invention relates to a solid-liquid fast separation device, which comprises a cylindrical barrel, a helical blade arranged in the barrel and a transmission device disposed outside the barrel. The upper end of the barrel is provided with a feeding hopper, the transmission device comprises a driving wheel and a driven wheel arranged at both ends of the barrel, the driving wheel is in transmission connection with a drive motor through a belt, a first stage separation plate and a second stage separation plate are disposed at an interval under the helical blade of the barrel, the first stage separation plate and the second stage separation plate are woven from a stainless steel screen, the aperture of the first stage separation plate is 30-50mm, and the aperture of the second stage separation plate is 10-25mm, a conical water collecting hopper is arranged below the second stage separation plate, the end of the water collecting hopper is provided with a water outlet, a fine sand outlet is arranged at the barrel end and between the first stage separation plate and a second stage separation plate, and the helical blade end is provided with a coarse material outlet. With a simple structure, the solid-liquid fast separation device realizes multistage separation, the separation efficiency is high, and the service life is long.

Description

technical field [0001] The invention relates to the field of dredging rivers, reservoirs and other water bodies with relatively high mud and sand content, in particular to a solid-liquid separation device. Background technique [0002] Groundwater in most cities in my country is subject to point and surface pollution to a certain extent, and it tends to increase year by year. The increasingly serious water sludge not only reduces the use function of water bodies, but further exacerbates the contradiction of water shortage, which has a serious impact on the sustainable development strategy being implemented in our country, and also seriously threatens the drinking water safety of urban residents and the people. the health of the masses. [0003] Most cities in my country lack water resources. With the acceleration of urban modernization in the future, the shortage of water resources will affect urban water supply. Sewage is a stable and reliable renewable water resource, an...

Problems solved by technology

[0004] The existing sewage solid-liquid separation device uses natural sedimentation, which takes a long time and has low efficiency. As a technical improvement, dynamic separation technology is used to filter and separate solid and liquid in a flowing state, such as screw extrusion, high-speed centrifugal filtration, and separation. The water quality is turbid, the suspended matter in the water cannot be removed, the discharge is not up to standard, and follow-up treatment is required, which increases the treatment cost
