Background The regenerated water source heat pump is one kind of high efficiency energy saving device with regenerated water as cold and heat source. The anti-blocking filter device is key front-end protection equipment in the regenerated water source heat pump system, and can prevent the impurities in the regenerated water from entering core equipment such as a subsequent heat exchanger and a water pump by intercepting the impurities, so that the pipeline is prevented from being blocked, the abrasion of the impurities on the equipment is reduced, the service life of the equipment is prolonged, the heat exchanger can be guaranteed to continuously and efficiently exchange heat, and the running stability of the system is improved. The utility model discloses an automatic back flush filter in patent document of publication number CN117138433B, including the jar body, the outer surface mounting that the jar body is close to its bottom has the feed liquor pipe, and the outer surface mounting that is close to its top has the drain pipe that extends to its inside, the inner wall fixed mounting that the jar body is close to its bottom has the baffle, and a plurality of water injection holes have evenly been seted up in the upper surface circumferencial direction of baffle, and the inner wall fixed mounting that the jar body is located the drain pipe top has the fixed disk, and a plurality of tube-shape filter cores are evenly installed to circumferencial direction between fixed disk and the baffle, and the bottom of filter core is open structure, and the filter core is linked together with the water injection hole, and the top fixed mounting of filter core has the pivot, and the top of pivot runs through the upper surface setting of fixed disk, installs a plurality of filter core pivoted rotary mechanism of drive on the fixed disk. When the back flushing operation is implemented, the sewage drain pipe is required to be respectively adjusted to be communicated with a corresponding single filter element, meanwhile, certain working water pressure is still kept in the tank body, under the driving of the water pressure, the flow distribution phenomenon can occur in filtered clean water reserved in the tank body, a part of clean water continues to maintain a normal water outlet flow, the clean water is continuously discharged through the liquid outlet pipe to ensure the continuity of subsequent water, the other part of clean water reversely flows through the filter element in a back flushing state at present, and the pollutant trapped on the inner surface of the filter element is stripped and flushed by the reverse impact force of water flow, then the pollutant is carried into the sewage drain pipe communicated with the filter element together, and finally the clean water is discharged out of the filter body to finish the back flushing cleaning of the single filter element. However, the scheme has the following problems that the design is subjected to the inherent requirement of the multi-core back flushing filter water outlet guarantee design, the liquid outlet pipe is required to be continuously kept open in the back flushing process so as to ensure that normal water supply is not interrupted, the design ensures that clean water in the tank body is split, most of water pressure is required to be used for maintaining the conventional water outlet flow of the liquid outlet pipe, further, the water flow pressure reversely flowing through the filter element to be back flushing is greatly split and weakened, the reverse impact force of the water flow is difficult to fully strip fine impurities trapped in the deep layer of the filter element, only part of floating dust pollutants on the surface of the filter element can be simply flushed, the back flushing cleaning effect of the filter element is finally seriously influenced, the filter element cannot be completely restored to the optimal through state, and the integral filtering efficiency of the filter can be continuously reduced under long-term operation. Disclosure of Invention The invention provides an anti-blocking filter device of a regenerated water source heat pump, and aims to solve the problem that the filter element is easy to be thoroughly cleaned due to insufficient backwash water pressure in backwash operation of the conventional matched filter device of the regenerated water source heat pump, so that the filter element affects the filtering efficiency.
