Solid-liquid separator

Abstract

The invention discloses a solid-liquid separator which comprises a machine body, a screen, a segment of water distributing trough located in the upper part of the machine body and a segment of mud collecting tank arranged at the lower part of the machine body, wherein a strip screen is adopted as the screen and is formed by arranging multiple rows of strips along the length direction of the machine body at intervals. The arranged water distributing trough plays a buffer role in a conveyed sewage mixture to limit the flow rate, so that the sewage mixture is prevented from being jet due to overlarge pressure or is prevented from being unevenly separated due to an over-high flow rate. By adopting the strip screen, bubbles cannot be easily formed on the surface, and the liquid is not prevented from flowing out, and the left sludge after separation can be timely discharged through the mud collecting tank, so that the solid-liquid separation effect is good.

Description

technical field [0001] The invention relates to a solid-liquid separation device, which is especially suitable for solid-liquid separation of high-concentration organic sewage. Background technique [0002] At present, the solid-liquid separation device can be widely used in the separation of animal feces in various intensive farms, and the separation of slag-liquid in high-concentration organic sewage such as distiller's grains, medicinal residues, starch residues, sauce residues, and slaughterhouses. The solid-liquid separation device is a solid-liquid separator. [0003] Existing solid-liquid separators generally use perforated screens, which have the following problems: when the pressure of the delivery pump is too high, it is easy to cause the sewage mixture to be sprayed out or the solid-liquid separation is uneven, and because of the tension of the liquid, it is easy to Air bubbles are formed on the surface of the screen mesh, which hinders the outflow of liquid, res...
