Feed water treatment filtering device

Abstract

The invention belongs to the technical field of feed water treatment, and particularly relates to a feed water treatment filtering device which comprises a through pipe, a first filtering plate is arranged in the through pipe, a first push rod is arranged on the through pipe in the diameter direction of the through pipe, a first telescopic structure is arranged at one end of the first push rod, and a first push plate is arranged at the other end of the first push rod. The first push plate is in contact with the first filter plate, an opening is formed in the pipe wall of the through pipe, a first containing box is connected to the position, located at the opening, of the outer portion of the through pipe, the first containing box communicates with the through pipe, and the opening is located between the push plate and the first containing box; according to the water supply device, the problem that in the prior art, the filter element can be detached for maintenance only when the filtering capacity of the filter element is reduced to the minimum, and then the water supply efficiency is reduced is solved.

Description

technical field [0001] The invention belongs to the technical field of water supply treatment, and in particular relates to a water supply treatment and filtering device. Background technique [0002] Water supply treatment is an important part of water supply engineering. Its task is to remove the various harmful impurities contained in the raw water through the process of dosing, mixing reaction, precipitation (clarification), filtration, and disinfection, and achieve water that meets the water quality standards for people's living and production. [0003] The Chinese patent with the publication number CN210631785U discloses a water treatment filter device, which is provided with a double filter channel, including a first filter tube and a second filter tube. The inside of the first filter tube and the second filter tube are provided with filter elements, When in use, use any one of the filter channels to filter, until the filter element in the filter tube affects the wat...

[0003] The Chinese patent with the publication number CN210631785U discloses a filter device for water supply treatment, which is provided with double filter channels, including a first filter tube and a second filter tube, and filter elements are arranged inside the first filter tube and the second filter tube, When in use, use any filter channel to filter until the filter element in the filter tube affects the water supply, switch to another filter channel to maintain the blocked filter channel. This device realizes uninterrupted maintenance, but in use It is necessary to wait until the filtration capacity of the filter element is reduced to the minimum before disassembling the filter element for maintenance. Then, during the period from the beginning of clogging to complete clogging, due to partial clogging, the capacity of treated water is reduced and the efficiency is reduced. If there is a little clogging, disassemble it Maintenance, the maintenance cost is high, so it is necessary to provide a filter device that can clean the blockage before it is disassembled for maintenance
