1、 Overview of Underground Online Self Cleaning Comprehensive Water Supply Purification Station

JXGSZ-70JB - ※ A type underground online self-cleaning comprehensive water supply purification station is a device independently developed by our company for underground water treatment based on the current water supply situation in coal mines. This equipment can be used as the overall water treatment equipment for the comprehensive mining face, providing a pure water source for the comprehensive mining equipment and other water equipment, ensuring the reliability of water equipment operation, and reducing the maintenance cost of water equipment. The equipment is directly placed on the rail car as a whole, the water inlet is connected with the underground water supply port, and the filtered purified water is connected with the working face water piping from the water outlet to supply water for the emulsion pump station, support, spray cooling, scraper conveyor, TTT cooler and other equipment. The pure water provided by this device completely solves the problems of unreliable operation, corrosion, scaling, and pollution of components related to the bracket emulsion system.

3、 Working principle and process of underground online self-cleaning comprehensive water supply purification station

　　Working principle of water filtration:The core technology of the inlet filter is a slotted stainless steel filter screen and a unique cleaning and backwashing structure. The gap type structure of the filter element has changed the traditional filter type structure. In order to improve the cleaning effect, stainless steel wire brushes are designed inside the mesh. The brush is manually driven to rotate and clean the dirt adhered to the inner wall of the filter.

The filter element is not woven with stainless steel wire, and a steel wire woven filter will increase the chance of dirt clogging the filter. The cross-section of the filter wire of the filter element is triangular, and its inner wall is smooth, which is conducive to cleaning the scraper and brush, while the outer mesh has a triangular opening. In this way, pollutants greater than or equal to the required filtration accuracy will not get stuck on the filter screen, keeping the filter in good working condition at all times.

The patented technology for backwashing the water inlet filter involves a rotating motion to clean, discharge, and change the direction of water flow through the gap type stainless steel filter. Under the scraping of the stainless steel brush, the dirt on the filter element is washed away and carried into the atmosphere by the water flow.

　　Working principle of precision filtration:The main determining factor for the quality of filtered water is the filter material. To measure the progressiveness of filtration technology, the following four aspects should be considered: 1) void ratio; 2) Speed; 3) , pollutant carrying capacity; 4) Accuracy; To achieve the goals of all four

Unification is an ideal filtering technology. The cleaning performance of filter media is crucial for filtration technology. Although there are the best filtration technologies

It is difficult to complete cleaning and refurbishment in the filter tank. After a long period of operation, it has been shown that the particle filter material has a good backwashing effect, which is evident to all; If the high filtration performance of fiber filter media can be combined with the good backwashing effect of particle filter media to form an ideal filter media.

Fiber particle filter material has the characteristics of an ideal filter material with a natural decrease in porosity from top to bottom in the filter layer formed during filtration, as well as strong adsorption. During backwashing, the filter material is fully dispersed and easy to clean.

This precision water filter is a specialized filter that uses fiber particle filter material as its technical core. Fiber particle filter material is a new type of filter material, which has the advantages of high filtration accuracy and large interception capacity of fiber filter material, as well as high backwash cleanliness and low water consumption of particle filter material. The porosity distribution of the filter bed formed by this filter material is close to the structure of ideal filter material. The porosity distribution is uniform in the cross-section (horizontal) of the filter bed; Ensure consistency in the size of the water flow channel during filtration; Its direct effect is to evenly intercept pollutants and avoid water flow short circuits. The diameter distribution of the vertical gap channels in the longitudinal section of the filter bed gradually decreases from top to bottom, and the diameter of the gap channels follows a gradient distribution with a larger diameter at the top and a smaller diameter at the bottom along the longitudinal section of the filter bed. This structure is very conducive to the effective separation of suspended solids in water, that is, particles desorbed from the upper part of the filter bed are easily captured and intercepted in the narrow channel of the lower part of the filter bed. Due to the uniqueness of the filter bed formed by fiber particle filter material, this precision water filter is able to achieve high-speed and high-precision filtration to meet the requirements of high water quality and large water volume.

During filtration, the pressure difference of water flow has a compacting effect on the fiber bundle. During backwashing, due to the difference in specific gravity between fiber particles and fiber bundles, the fiber bundles disperse and oscillate with the backwashing water flow, generating strong drag force. The collision between filter media also intensifies the force acting on the fibers in the water. The irregular shape of the filter media causes it to rotate under the backwashing water flow, enhancing the force acting on the filter media during backwashing. The combined effect of these forces makes it easy for dirt particles attached to the fiber surface to fall off, thereby improving the cleanliness of the filter media during backwashing. The patented technology of backwashing hydraulic motor achieves flexible flushing of filter material without damaging the filter material.

　　Working principle of RO reverse osmosis:The application of reverse osmosis phenomenon removes most of the ions in water, producing pure water, changes the chemical properties of water, and generates a certain amount of wastewater, which is a type of cross flow filtration. Unique design enables automatic operation of reverse osmosis without electricity. The pure water used in RO reverse osmosis is deionized water, with 98% of ions removed from the water. The water has low hardness and extremely low corrosiveness, which can fully meet the requirements of emulsion water distribution and greatly improve the operational reliability and service life of the components related to the bracket emulsion system.
