Filtering device with self-cleaning function

Abstract

The invention relates to a filtering device with a self-cleaning function. The filtering device comprises a tank body, an upper cover assembly is arranged at the upper end of the tank body, a self-cleaning filter element is arranged in the tank body, a suction disc assembly is arranged in the self-cleaning filter element, a pre-filter element is arranged at the lower end of the self-cleaning filter element, the upper end of the suction disc assembly is fixedly connected to a geared motor mounted on the upper end of the upper cover assembly via a connecting shaft, the tank body comprises a cylinder body disposed at the upper end of a mounting seat, an end cover is disposed at the upper end of the cylinder body, the side wall of the cylinder body is provided with an oil inlet and an oil outlet, the oil inlet is located at the lower side of the oil outlet, a position, located between the oil inlet and the oil outlet, on the inner side wall of the cylinder body is provided with a separation plate used for separating and fixing the self-cleaning filter element and the pre-filter element, the center position at the bottom end in the cylinder body is provided with a fixed seat, and the lower end of the fixed seat is connected with a discharge valve arranged outside the cylinder body via a discharge pipe. The filtering device of the invention solves the problem that an existing self-cleaning filter in a lubricating oil system requires a more self-cleaning flow rate and the pressure fluctuation of subsequent equipment is large due to an uneven flow of a self-cleaning liquid.

Description

Technical field [0001] The invention relates to a filter device with self-cleaning function. Background technique [0002] Filter equipment plays an important role in ensuring the normal operation of the lubricating oil system. The traditional filter requires the operator to frequently replace, clean or scrape the filter element, which not only increases the labor intensity of the operator, but also cannot meet the overall requirements. Requirements for automation. The self-cleaning filter is widely used due to its advantages such as high degree of automation, non-stop operation, long overhaul period, less spare parts for filter element, and low labor intensity of operators. [0003] The self-cleaning filter can use certain conditions (such as filtered clean liquid, compressed air, etc.) to automatically remove the pollutants trapped on the filter element and restore the filter channel of the filter element. The self-cleaning filter belongs to the most advanced filtration equipme...
