Mining filter element cleaning process

Abstract

The invention discloses a mining filter element cleaning process and provides a clean and efficient filter element cleaning process. The invention adopts the following technical scheme: the mining filter element cleaning process comprises the following steps: 1, removing oil: adopting warm water at the temperature of 35 to 55 DEG C in an oil-removing cleaning tank, adding an oil-removing agent andperforming soaking oil removal; 2, cleaning for the first time: cleaning a mining filter element soaked in the step 1 with clean water in the cleaning tank; 3, performing ultrasonic cleaning: puttingthe mining filter element which is completely washed in the step 2 into an ultrasonic cleaning machine and cleaning; 4, cleaning for the second time: putting the mining filter element which is cleaned in the step 3 into the cleaning tank and soaking and cleaning; 5, descaling: putting the filter element which is soaked and cleaned into a rust-removing scale cleaning tank and soaking; 6, cleaningfor the third time: putting the mining filter element which is soaked in the step 5 into the cleaning tank and completely washing with clean water; 7, performing high-pressure backwashing; 8, performing filter element experiment, if qualified, entering a step 9 to perform packaging, and if unqualified, returning to the step 1 to clean again; 9, drying; and 10, performing thermal shrinkage packaging.

Description

technical field [0001] The invention relates to a cleaning process specially used for mining filter elements. Background technique [0002] With the upgrading of coal mine automation, the requirements for underground water quality are getting higher and higher, and the number of underground water treatment equipment involved is also increasing accordingly, and the application of mining filter elements is becoming more and more extensive. The work of maintaining and cleaning mining filter elements has become increasingly important, so the design and manufacture of filter element cleaning production lines, cleaning process, and cleaning methods have become very important. [0003] At present, there is no specialized automated high-pressure backwashing equipment to meet the requirements of industrialization and scale, and there is also a lack of specialized cleaning equipment after cleaning, which makes it difficult to guarantee the quality of cleaning. Therefore, it is immine...

AI Technical Summary

Problems solved by technology

[0006] 1. The equipment process is incoherent, the cleaning efficiency is low, and it is all manual cleaning, which requires a lot of physical labor;

[0007] 2. Incomplete cleaning: Cleaning the filter element does not distinguish the components of the pollutants in the filter element, and it is cleaned together. The filter element is used in the filtration of the downhole hydraulic circuit. The downhole hydraulic pressure is an emulsion, and the emulsion is composed of emulsified oil and water;

[0008] 3. There is no measuring equipment, and it is all based on intuition to judge whether the cleaning is good or bad;

[0009] 4. There is no packaging link, which may cause secondary pollution to the filter element in a humid environment. Dust and water vapor in the air will cause secondary pollution to the filter element
