Description

Technical Field

[0001] The utility model relates to the technical field of water filtration of evaporative condensers, in particular to a filtering structure of a circulating pump for an evaporative condenser. Background Art

[0002] The cooling circulating water evaporates in the condensing coil, and the gaseous ammonia condenses into liquid in the condensing coil, so it is called an evaporative condenser. The high-intensity evaporation makes the evaporative condenser more prone to scaling than other types of condensers. There is currently no ideal descaling method, and severely scaled evaporative condensers lose their power-saving advantages.

[0003] Part of the scale is washed down into the sump by the water flow, and eventually the scale flows with the circulating water to the circulating pump. If the scale is not treated, it may cause blockage of the water pipe, increased wear of the circulating pump, or blockage of the nozzle. For this reason, the present application proposes a filtering structure for a circulating pump for an evaporative condenser. Utility Model Content

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes a filtering structure of a circulating pump for an evaporative condenser, comprising:

[0021] A mounting base 1, wherein four mounting holes 2 are formed on the mounting base 1, and the four mounting holes 2 are distributed in a rectangular shape. The mounting base 1 can be installed in the water tank by passing bolts through the mounting holes 2;

[0022] A filtering mechanism is mounted on the mounting base 1; the filtering mechanism comprises a water tank 3 mounted on the mounting base 1, a circulating pump 5 is provided on one side of the water tank 3, a delivery pipe 4 is installed at the water inlet end of the circulating pump 5, and the delivery pipe 4 is connected to the water tank 3.

[0023] A threaded pipe 11 is fixed to the upper end of the water inlet pipe 8, and the threaded pipe 11 and the water inlet pipe 8 are integrally formed by casting; two water inlet pipes 8 are installed on the water storage tank 3, and a valve 7 is installed on the water inlet pipe 8. A reducer 10 is threadedly connected to the upper end of the water inlet pipe 8, and a threaded pipe 11 is fixed to the upper end of the water inlet pipe 8. A threaded ring 9 is fixed to the bottom of the reducer 10, and the threaded ring 9 is sleeved on the outside of the threaded pipe 11 and threadedly connected to it.

[0024] A threaded ring 9 is fixed to the bottom of the reducer 10, and the threaded ring 9 and the reducer 10 are integrally formed by casting; the threaded ring 9 is sleeved on the outside of the threaded tube 11 and threadedly connected thereto; a filter screen cylinder 6 is installed at the upper end of the reducer 10, and the circulating water is filtered through the filter screen cylinder 6.

[0025] Specifically, the mounting base 1 and the water storage tank 3 are installed in the water tank, the filter screen cylinder 6 is located below the circulating water level, the circulating water enters the water storage tank 3 through the filter screen cylinder 6, and the circulating pump 5 works to output the water in the water storage tank 3 through the delivery pipe 4, so that the circulating water in the water tank can continuously pass through the filter screen cylinder 6 and enter the water storage tank 3, and the filter screen cylinder 6 can be used to filter the circulating water, so as to avoid the blockage of the water pipe, the increase of the wear of the circulating pump, or the blockage of the nozzle;

[0026] When it is necessary to disassemble and clean the filter screen cartridge 6, the staff closes the valve 7 corresponding to the filter screen cartridge 6 to be removed, and then rotates the reducer 10 to separate the threaded ring 9 from the threaded tube 11, and the filter screen cartridge 6 can be removed. Since the valve 7 closes the circulation of the water inlet pipe 8, the circulating water that has not passed through the filter screen cartridge 6 will not enter the water storage tank 3 through the water inlet pipe 8; the two filter screen cartridges 6 can be cleaned alternately to achieve the cleaning of the filter screen cartridge 6, and the operation is simple and convenient.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
