Cooling water pipeline filtering device

Abstract

The invention discloses a cooling water pipeline filtering device which comprises a filter screen assembly and a magnetic attraction assembly. The filter screen assembly comprises solid parts and filter screen parts which are fixed with each other, the filter screen parts are arranged at the upper right end and the lower left end, and the solid parts are arranged at the lower right end and the upper left end; two filter screen plates arranged in parallel are fixedly connected in the inner cavity of the filter screen assembly, inserting holes are formed in the filter screen plates, and the twofilter screen plates sequentially divide the inner cavity of the filter screen assembly into a fine filter cavity, a middle filter cavity and a coarse filter cavity. The structure of the magnetic attraction assembly is formed by buckling and assembling the circular magnet rings one by one, the filtering effect is better, the device is easy to disassemble, assemble and clean, the structure is simple, the cost is low, operation is convenient, the filter screen cannot be blocked and the cleaning process is simplified.

Description

technical field [0001] The invention relates to the technical field of magazine filtering, in particular to a cooling water pipeline filtering device. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the back end of the pressure reducing valve, pressure relief valve, and water level valve to filter impurities in the pipeline, thereby protecting the purity of the fluid in the pipeline. When the fluid passes through the filtration system, the impurities in it are filtered out and the clean liquid is purified. When it needs to be cleaned, just take out the filter for cleaning, so it is very convenient to use and maintain. The traditional industrial filter is a simple filter screen. The filter screen is not effective in filtering small metal impurities such as iron filings in the fluid; at the same time, encountering larger metal impurity particles will cause the filter screen to be clogged and affe...

Problems solved by technology

[0005] However, during the use of the above-mentioned magnetic filter, there are still obvious defects: the magnetic suction effect is single, and the flow direction of the water flow in the water pipeline cannot be controlled, so it is difficult to make the water flow fully contact with the magnetic suction parts, resulting in the adsorption of iron The efficiency of impurity particles becomes poor, and it is impossible to adsorb and remove iron impurities in water pipes in a limited space with higher efficiency, and the removal efficiency of impurities is low
