Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a flow guide filter suitable for a river water source heat pump system. Background Art

[0002] The river water source heat pump system is a water source heat pump system that uses river water. The working principle of the river water source heat pump unit is to transfer the heat in the building to the river water source in summer. Since the temperature of the river water source is low, it can efficiently take away the heat. In winter, energy is extracted from the river water source, and the heat pump principle is used to increase the temperature through air or water as a coolant and then sent to the building.

[0003] Since the river water source heat pump has low operating costs, the average cost is lower than the traditional air conditioning water system during the entire service life, and it has the characteristics of environmental protection and energy saving. However, compared with the traditional air conditioning water system, the river water source heat pump system has poorer water quality, which contains more sediment and various impurities, and requires frequent filter cleaning. Therefore, when the water quality is poor, ordinary diversion filters may be difficult to meet the requirements of filtration, sewage discharge and cleaning maintenance.

[0004] Existing patent No. 2020223830012 discloses a sewage filter that is convenient for diversion. The utility model discloses a sewage filter that is convenient for diversion, including a base, a water tank, a water pump 2, a high-pressure water pipe, a telescopic cylinder, a fixed connecting rod, a filter brush, a water inlet pipe, a water pump 1, a filter, a filter 1, a filter 2, a diversion pipe, a high-pressure nozzle and an inlet pipe. A water pump 1 is arranged above the filter, and the right side of the water pump 1 is connected to the water inlet pipe. A filter 1 is installed on the inner side of the filter, and a filter brush is arranged above the filter 1. A telescopic cylinder is connected to the left side of the filter brush, and a fixed connecting rod is arranged above the telescopic cylinder. A high-pressure water pipe is arranged below the telescopic cylinder, and high-pressure nozzles are connected on both sides of the high-pressure water pipe.
