Fishpond filter

Abstract

The invention discloses a fishpond filter which is characterized in that the fishpond filter is a sealed barrel-shaped sealed container, a filter material is arranged in the container, a water inlet pipe is arranged at the bottom of the container, a water outlet pipe is arranged at the top of the container, and a blow-off pipe and a backwashing pipe are further arranged at the bottom of the container. Compared with the prior art, the fishpond filter has the advantages that physical filtration and biochemical filtration are integrated, water is kept clear forever and good in water quality through continuous circulating filtration, automatic backwashing pollution discharge is controlled by a time controller, and the filter does not need to be manually cleaned all the year round. The MBBR filler is used for fishpond water treatment, automatic backwashing pollution discharge controlled by the time controller is achieved, the problem that an existing fishpond filter needs to be frequently cleaned manually for pollution discharge is solved, and the fishpond filter is small in size, light in weight and convenient to install.

Description

technical field [0001] The invention relates to aquaculture filter equipment, in particular to a fish pond filter. Background technique [0002] Most of the existing water bodies such as fish ponds and waterscapes do not have filtering devices, and they will soon become turbid, green and smelly, and the fish they raise will often die, so they have to change the water and wash the pond frequently, which consumes a lot of manpower and material resources. Some pisciculture enthusiasts have to build a very large filter tank while building the tank, and fill various filter materials therein for circulating filtration. The filter materials in the existing filter media are mostly ceramic rings, crushed coral, quartz sand, anthracite and other filter materials. The use of such filter materials has low filtration accuracy, small dirt holding capacity of the filter bed, and low filtration speed. Later, fiber synthetic Filter material, although this kind of filter material can make up...

Problems solved by technology

[0002] Most of the existing water bodies such as fish ponds and waterscapes do not have filtering devices, and they will soon become turbid, green and smelly, and the fish they raise will often die, so they have to change the water and wash the pond frequently, which consumes a lot of manpower and material resources. Some fish lovers have no choice but to build a large filter tank while building the tank, and fill it with various filter materials for circulating filtration.

The filter materials in the existing filter media are mostly ceramic rings, crushed coral, quartz sand, anthracite and other filter materials. The use of such filter materials has low filtration accuracy, small dirt holding capacity of the filter bed, and low filtration speed. Later, fiber synthetic Filter material, although this kind of filter material makes up for the defects of traditional particle filter material, but because of the small difference in specific gravity with water, the cleaning effect of the synthetic fiber formed body filter material is poor, and the fiber is easy to lose during backwashing

There are also a small number of pond filters that use sponges as filter materials on the market, but whether it is a brick-concrete filter pond or a commercially available pond filter, it will be quickly blocked by the filtrate and require manual cleaning
