Description

Technical Field

[0001] The utility model relates to the technical field of filtering, in particular to a cooling water pre-filtering device. Background Art

[0002] A chiller is a water cooling device that can provide constant temperature, constant flow and constant pressure. The principle of a chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the chiller refrigeration system, and then the water pump inside the machine injects low-temperature frozen water into the equipment that needs to be cooled. The chilled water takes away the heat inside the machine and returns the high-temperature hot water to the water tank for cooling. The cooling is circulated and exchanged in this way to achieve the effect of cooling the equipment. If the water provided by the outside is directly connected to the chiller in the prior art, the working efficiency of the chiller will be affected due to the large amount of impurities in the water. Moreover, long-term use of such water with poor water quality will shorten the service life of the chiller.

[0003] Existing cooling water pre-filter devices are generally equipped with backwash devices, which generally scrape the filter screen through a scraper. When large particles such as rust are stuck between the scraper and the housing, the backwash device may fail, making it difficult to clean the filter screen. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a cooling water pre-filter device to solve the technical problem that when large particles such as rust are stuck between the scraper and the housing, the backwash device may fail.

[0016] Furthermore, a plurality of the vertical pieces are provided, one end of each of the plurality of vertical pieces is fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the housing.

[0017] By adopting the above technical solution, multiple vertical sheets can increase the contact area between the cleaning mechanism and the filter screen and the inner wall of the outer shell, thereby improving the cleaning efficiency. The multiple vertical sheets are fixedly connected by a rotating shaft at one end and are rotatably supported by the outer shell, so that the first cleaning mechanism can remain stable during rotation, ensuring that the first scraper on each vertical sheet can evenly and effectively scrape off impurities.

[0018] Furthermore, a second cleaning mechanism is rotatably connected inside the shell, and the second cleaning mechanism includes an inner vertical piece and an outer vertical piece.
