Solid-liquid separator

Abstract

The invention discloses a novel solid-liquid separator. Upper and lower circular seal heads of a cylinder body are connected with circulation pipes of a forced circulation evaporation tank; the cylinder body is internally provided with direct-flow baffles and a deflection baffle; one side of the cylinder body is provided with an upper clean liquid outlet and a lower clean liquid outlet which are distributed at the direct cylinder section in symmetrical with a central axis; the direct-flow baffles are arranged at the connection parts of the upper and lower circular seal heads and the direct cylinder section, and are parallel to the circulation pipes; the direct-flow baffle arranged at the upper seal head in length direction exceeds the joint part of the seal heads and the direct cylinder section, and the direct-flow baffle arranged at the lower seal head in length direction is within the joint part of the lower seal head and the direct cylinder section; the deflection baffle consists of two parts including an inclined baffle and a vertical baffle, and the connection part of the baffle at the inclined part and the cylinder body are between the upper clean liquid outlet and the lower clean liquid outlet of the cylinder body; the angle between the inclined baffle and the vertical baffle is an obtuse angle; the baffle at the vertical part and the direct-flow baffle at the same side are at the same straight line. Separated solid salt particles are less in particle size, are high in recovery rate, and have good effect.

Description

technical field [0001] The patent of the present invention relates to separation equipment, especially a solid-liquid separator for separating mother liquid containing calcium sulfate seed crystals from powdered salt. Background technique [0002] The salt mother liquor contains part of the powder salt mixed with calcium sulfate seeds. When transferring materials, it is hoped to separate the mother liquor from the powder salt to recover the salt particles. It is difficult for ordinary pipelines to achieve this separation effect for further treatment of the mother liquor. , Therefore, a solid-liquid separator is adopted. The existing common solid-liquid separator can only separate larger solid salt particles, the recovery rate is not high, and the effect is not ideal. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention proposes a new type of solid-liquid separator, the separated solid salt particle size is smaller, the r...
