Description

Technical Field

[0001] The utility model relates to water treatment equipment, in particular to a filter. Background Art

[0002] The filter in the prior art includes a tank body, a tank cover, a partition and a filter rod; the tank cover is sealed and connected to the tank body; the partition seals and separates the cavity of the tank body from the cavity of the tank cover; there are multiple filter rods; multiple filter rods are placed in the cavity of the tank body; multiple filter rods are distributed on the plate surface of the partition; the upper end of each filter rod passes through the tank cover in a sealed manner. After long-term use, the filter rod inside the filter will be clogged with dirt. In order to solve the problem of clogging of the filter rod, the dirt on the filter rod is usually removed by backwashing. Since the dirt is firmly attached to the filter rod, it is difficult to completely remove the dirt on the filter rod by backwashing alone, which is not only time-consuming, water-consuming and electricity-consuming, but also the filter rod cannot meet the filtering requirements after several backwashings, and can only be replaced with a new filter rod, which greatly wastes manpower, material resources and financial resources, and the efficiency of backwashing and sewage discharge is low. Taking a 2,000-cubic-meter traditional swimming pool with three filters as an example, the total flow rate is 450 cubic meters per hour, backwashing is done 120 times a year, each time takes 14 minutes and 24 seconds, and the annual backwashing time is 1,728 minutes. The water consumption for each backwash is 108 cubic meters, and the annual backwashing water consumption is 12,960 cubic meters. The electricity consumption is 10.8 degrees each time, and the annual electricity consumption is 1,296 degrees. Under normal circumstances, the filter needs to be replaced every 6-12 months.
