Tower type double-flow water filtering cap

Abstract

The invention discloses a tower type double-flow water filtering cap which comprises a cap head and a cap cake, wherein a hollow flow passage is positioned at the center of the cap cake, a first water filtering gap is arranged on the cap head, a second water filtering gap is arranged at the upper end of the hollow flow passage of the cap cake, and the second water filtering gap is communicated with the first water filtering gap; the tower type double-flow water filtering cap is characterized in that a flow control body is arranged in the hollow flow passage, the flow control body can move up and down under water pressure, and the height at the position of the largest cross section of the flow control body is larger than the height of the lower end of the second water filtering gap. The flow control body is a spherical or cylindrical body. Compared with the prior art, the flow control body capable of moving along with the water flow direction is designed and added on the water filtering cap structure of the invention, the flow control body preferably is a spherical ball or a cylindrical body and has excellent reflux effect, thereby the normal operation of equipment is ensured, the operation and production efficiency is improved, and the operation and maintenance cost is also lowered.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a tower-type water filter cap used for sewage treatment equipment. technical background [0002] Existing special water filter caps (such as filters) for water treatment equipment, the running water of the water cap and the flow channel of the backflow cleaning water are the same, both of which are the inner diameter of the cap cake, which can only ensure the design flow of the water cap, so that the water cap The operating flow rate is almost the same as the reverse flow rate, and the reverse flow effect is poor. The raw material particles that block the gap of the water cap are not easy to be cleaned, which will affect the operating efficiency of the equipment and the service life of the water cap. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tower-type water filter cap with large reverse flow rate and...
