Simple tubular filter

Abstract

A simple tubular filter comprises a baffle, a filter tube and a flange. The baffle is fixedly connected with the filter tube, and the filter tube is in threaded connection with the flange. The simple tubular filter is applicable to the field of wet-process smelting for treatment of various materials and can greatly decrease the time required by dredging of a blocked position and downtime, ensure production continuity, stabilize control of technical indexes, improve the product quality and reduce the working intensity of workers.

Description

technical field [0001] The invention relates to a pipeline dredger suitable for processing various materials in the field of wet smelting, in particular to a pipeline dredger for handling materials with large specific gravity and fast sedimentation speed. Background technique [0002] In the process of processing non-metallic high-nickel matte, coarse-grained alloys, fine-grained alloys and other materials by pressure leaching technology, due to the large proportion of such materials and the fast settling speed, if there is debris blocking, the flow rate of the slurry will decrease. , resulting in frequent blockage of the pipeline, this problem is the only obstacle affecting the maturity of the pressure leaching technology, and once the pipeline is blocked, production needs to be stopped for treatment, and the front and rear ends of the blocked pipeline need to be disconnected for dredging. During the whole dredging process, the amount of disassembly and assembly is large, t...

AI Technical Summary

Problems solved by technology

During the whole dredging process, the amount of disassembly and assembly is large, the shutdown time is long, and the labor intensity of personnel is high, which seriously affects the continuous stability of production and the control of technical indicators, reduces the quality of the finished liquid, and restricts the completion of the goal of "energy saving and efficiency enhancement".

At the same time, if the pipe is too long to be dredged, it needs to be replaced with a new pipe, which will cause a large consumption of pipe materials

Moreover, because the non-metallic high-nickel matte, coarse-grained alloy, and fine-grained alloy pressure leaching technology is a sulfuric acid leaching process under the condition of oxygen, the time to stop production and dredge the pipeline is too long, which will cause fluctuations in technical indicators. Fluctuations can lead to H 2 S gas is produced, which will seriously threaten the physical and mental health of employees
