[0002] A high-pressure cleaning pump is an efficient, high-pressure and energy-saving cleaning device, which is used for cleaning heat exchangers or reaction kettles and various pipelines in industries such as chemical plants, thermal power plants, sugar factories, and paper mills.

[0003] Generally, a filtering device is not provided inside a general high-pressure cleaning pump for filtration. Instead, an external filter is used to filter impurities. Then, under high-pressure operation, the impurities in the external filter are crushed and dispersed and then ejected. However, there will also be impurity flow inside the high-pressure cleaning pump. These impurities will affect the inside during the operation of the high-pressure pump. The internal channel structure of the high-pressure pump is small, and some very small impurities can cause internal blockage and other situations.

[0004] Therefore, the utility model provides a high-pressure cleaning pump with a filtering function, in which a fine filtration system is arranged inside the high-pressure pump body to filter the liquid, avoiding internal blockage and poor operation caused by the output of impurities. And a single-blade scraper paddle is arranged in the filter net device, so that impurities will not form an obstruction to the filter net device during operation. Summary of the Utility Model
