No-clean water dirt separating filter

Abstract

A no-clean water dirt separating filter comprises a tank. The bottom of the tank is provided with a water guiding inlet and a sewage draining port, the top of the tank is provided with a drainage outlet, the tank forms a water flow channel flowing to the top from the bottom, a filtering layer is arranged in the flow channel and comprises a first filtering plate arranged on the upstream part of the flow channel and a second filtering plate arranged on the downstream part of the flow channel, and the first filtering plate and the second filtering plate are provided with hole grooves. An inner cavity of the filtering layer is encircled by the first filtering plate, the second filtering plate and a side wall of the flow channel, a filter material layer composed of a spherical filter material and with the weight smaller than or equal to the displacement of the inner cavity is installed in the inner cavity, the filter material layer occupies part of the volume of the inner cavity, and the spherical filter material is provided with an activity space. Aquaculture water is led into a dirt sedimentation channel through the water guiding inlet positioned at one end of the dirt sedimentation channel and fills the dirt sedimentation channel and the filtering layer, the water is discharged out of the drainage outlet above the filtering layer, and at the time, the spherical filter material of the filtering layer is positioned between the first filtering plate and the second filtering plate which have limiting effect. A filtering system formed by series connection of the filters is further included.

Description

Technical field [0001] The invention relates to a cleaning-free water and sewage separation filter, which belongs to the technical field of water and sewage separation and filtration of water bodies such as courtyard pools and fish tanks for cultivating ornamental fish. Background technique [0002] At present, the water purification of garden pools and fish tanks for cultivating ornamental fish is a research hotspot in the field of aquarium. There are usually solid wastes such as feed residues, fish feces, and rotten aquatic plants in the water body of ornamental fish, and these wastes will decompose into ammonia nitrogen, and form nitrite and nitrate, causing algae to grow; the waste in the water body Existence not only makes the water turbid and affects the appearance, but also causes the disease or death of aquatic animals. The current treatment methods for ornamental fish breeding water mainly use physical filtration to filter solid dirt, and biological filtration to a...

AI Technical Summary

Problems solved by technology

The filter material of the current physical filter mostly uses biochemical cotton, sponge, ceramic ball, quartz sand, etc., which are easily blocked by solid dirt. When cleaning, the filter material usually needs to be taken out and cleaned before loading. The cleaning is cumbersome and troublesome.

At present, there is also research on filters with cleaning functions. For example, patent 028170032 proposes a filter for garden pools, etc., which can squeeze and relax the filter cotton to clean the filter cotton. However, due to structural problems, it needs to be stabilized. The cleaning operation can only be carried out after the filter, which makes the operation inconvenient

Patent 200820083471.3 proposes a filter with filter cotton cleaning device, which is equipped with a lever-type cleaning device for squeezing filter cotton, but the cleaning of the filter material is not thorough, and the dirt in the filter material will fall off during cleaning, and some parts are not cleaned. The discharged dirt will re-enter the aquaculture water body and cause the water body to be turbid

During the cleaning process, the beneficial bacteria attached to the filter material will be destroyed, which affects the biological filtration effect in the filter system

There are also researches on water and sewage separation and filtration technology that reduce the cleaning workload, such as patent 201210574145.3, but it can only reduce the workload of cleaning the filter material, and cannot fundamentally eliminate the work of cleaning the filter
