High efficiency coarse particle separator

Abstract

Relating to the field of industrial machinery, the invention discloses a high efficiency coarse particle separator, which includes a screw shaft, a shell, an upper support, a lower support, a sewage sludge tank, a separation tank, a sludge discharge port, a deceleration body and a U-shaped tube. The end of the U-shaped tube is connected to a seamless steel tube, which is connected to the upper surface of the screw shaft. The upper support and the lower support are both equipped with a gasket. The sewage sludge tank is internally provided with a magnetic coagulator, and the separation tank is internally provided with a particle coagulator to accelerate precipitation and enhance precipitation efficiency. The use of the seamless steel tube can prevent the sludge from gathering at the end of the U-shaped tube. When the gap between the screw shaft and the shell increases, the gaskets can be extracted to decrease the gap. With the advantages of simple design and good separation effect, the high efficiency coarse particle separator is worthy of popularization.

Description

Technical field [0001] The invention relates to the field of industrial machinery, in particular to a high-efficiency coarse particle separator. Background technique [0002] At present, there are many problems in the processing process of the West Local Tax on the converter steelmaking dust removal. The authorization announcement number is CN 2680329Y, the authorization announcement date is February 23, 2005, and the patent name is a utility model patent for coarse particle separation device. Some problems, due to the mixing of magnetic and non-magnetic substances in the dust-removing sewage, and the small particles of the dust-removing sewage, resulting in slow sedimentation speed and low efficiency; due to the friction between the screw shaft and the sludge, the screw shaft and the shell The increase in the gap between the two leads to a decrease in the sludge output effect; the sludge tends to accumulate at the end of the U-shaped pipe to form a sediment. Summary of the inve...

Problems solved by technology

[0002] At present, there are many problems in the process of dust removal and sewage treatment in converter steelmaking. The authorized announcement number is CN 2680329Y, and the authorized announcement date is February 23, 2005. The patent name is a utility model patent for coarse particle separation device, which still exists. Some problems, due to the mixing of magnetic and non-magnetic substances in the dust removal sewage, and the small particles of the dust removal sewage, the sedimentation speed is slow and the efficiency is low; due to the friction between the screw shaft and the sludge, the screw shaft and the shell The gap between them increases, resulting in a decrease in the sludge discharge effect; sludge is easy to accumulate at the end of the U-shaped tube to form sediment
