Settling separation device

Abstract

The invention provides a settling separation device. The settling separation device comprises a through groove body, wherein the upper portion of the groove body is a cylindrical body, the lower portion of the groove body is a conical cylinder, a top beam is arranged at the top end of the groove body, a solid discharging hole is arranged at the lower end of the conical cylinder of the groove body, a charging hole and an overflow hole are arranged on the side wall of the cylindrical body of the groove body respectively, a through feeding drum is arranged coaxially inside the groove body, the upper portion of the feeding drum is a frustum, the lower portion of the feeding drum is a cylindrical body, the upper end of the feeding drum is fixed with the top beam of the groove body, the height of the feeding drum is not higher than that of the cylindrical body of the groove body, the charging hole is communicated with the frustum at the upper end of the feeding drum through a charging pipe, two layers of horizontal partition boards are arranged between the cylindrical body of the feeding drum and the cylindrical body of the groove body, inner ends of horizontal partition boards and outer ends of horizontal partition boards are fixed on the cylindrical body of the feeding drum and the cylindrical body of the groove body respectively, a settling pipe which forms a settling channel penetrates through the two layers of partition boards, and an umbrella-shaped device is coaxially arranged inside the feeding drum. The device eliminates a plurality of defects of the prior art, the rapid and effective settling is achieved, and simultaneously, the occupied area is reduced.

Description

technical field [0001] The invention relates to chemical industry separation technology, in particular to a settling separation equipment. Background technique [0002] Settling separation equipment is the most widely used liquid-solid separation equipment in the chemical industry. Among them, the settling tank is one of the most common settling separation equipment. It uses the settling area as the basis for calculating the settling capacity. Whether it is single-layer settling or multi-layer settling, the production capacity is increased by increasing the area. The increase of the area of ​​the settlement tank is a difficult choice for the production enterprises whose site area is decreasing day by day and the cost of land use is increasing year by year. For example, in the technology of using fly ash to produce active calcium silicate, the pre-desilication process is an important link, and it is necessary to settle the silicon-calcium slag from the aluminum-containing cr...

Problems solved by technology

For example, in the technology of using fly ash to produce active calcium silicate, the pre-desilication process is an important link, and it is necessary to settle the silicon-calcium slag from the aluminum-containing crude liquid. However, the current production process mostly uses a settling tank, which occupies a large amount of time. Factory area
