Pond filter

Abstract

The invention discloses a pond filter, which comprises a water inlet pipe and a water outlet pipe. A first three-way valve is arranged on one side of the water inlet pipe, and the upper part of the first three-way valve is fixedly connected with a first connecting pipe. , and the bottom of the first three-way valve is fixedly connected with the second connecting pipe, one side of the first connecting pipe is connected with the first filter chamber, and one side of the second connecting pipe is connected with the second filter chamber, so Sewage outlets are arranged below the first filter chamber and the second filter chamber. In the present invention, two parallel filter chambers are used to connect between the water inlet pipe and the water outlet pipe through a connecting pipe. When in use, a single filter chamber works, and another filter chamber can be adjusted to use for a period of time or when the filter chamber is blocked, and The clogged filter chamber is cleaned and discharged, so as to ensure the uninterrupted operation of the entire filter system, and at the same time avoid the impact on the filter work of the pond due to clogging.

Description

technical field [0001] The invention relates to the technical field of farming equipment, in particular to a pond filter. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and fence farming. High-density intensive farming uses methods such as running water, temperature control, oxygen...

AI Technical Summary

Problems solved by technology

[0003] However, existing pond filters still have deficiencies in use. First, most of them are single-channel to achieve filtration, and pond filters need to be filtered continuously. This single-pipeline work is very easy to cause blockage The filtration work is interrupted, and the treatment after clogging is difficult to deal with; secondly, because the diverted water has a certain corrosiveness, the pipes made of metal alone are easy to corrode after long-term use
