Microfiltration device with sedimentation bin for submerged cultivation

Abstract

The invention discloses a microfiltration device with a sedimentation bin for submerged cultivation. The microfiltration device comprises a rotary drum, the precipitation bin, a backwashing device anda mounting mechanism, the backwashing device comprises a central pipe, a booster pump, a backwashing pipe, a dirt collecting disc and a transmission mechanism, a sewage discharging pipe and a water inlet pipe which are concentric are arranged on the left side and the right side of the central pipe respectively, the two pipes are separated by a certain distance to serve as water outlets and are connected into a whole through a connecting strip, the dirt collecting disc and the backwashing pipe are installed over the center pipe, a transmission mechanism is installed on the left side of the center pipe, a water inlet pipe on the right side of the center pipe is communicated with the sedimentation bin, and the center pipe serves as a shaft and is provided with the rotary drum; the dirt collecting disc is funnel-shaped, the lowest part of the dirt collecting disc is communicated with the sewage discharging pipe, the backwashing pipe is arranged right above the dirt collecting disc, the backwashing pipe is a pipe with two closed ends, a plurality of spray heads are arranged right below the backwashing pipe through holes, and a water supply pipe is arranged on the side surface of the backwashing pipe through holes and is communicated with the booster pump.

Description

technical field [0001] The invention belongs to the technical field of aquaculture water treatment equipment, and in particular relates to a microfiltration device for submerged aquaculture with a sedimentation chamber. Background technique [0002] The industrial recirculating aquaculture method is gradually accepted by people and more and more applied to production practice due to its advantages of environmental friendliness, energy saving and water saving. The factory recirculating aquaculture system (RAS) can provide a controlled environment, the size of the system is not limited by environmental conditions, the growth rate of aquaculture products can be controlled, and the output can even be predicted. Compared with traditional breeding methods, the recirculating aquaculture production method can save 90-99% of water consumption and 99% of land occupation per unit of production, and hardly pollute the environment. Water treatment is the most important part of the indus...

Problems solved by technology

Now the water level of many farms is deep, and the filter tank has been completed, so it is not easy to install, and the installation of the drum is not easy to position, and it is inconvenient to replace the filter screen later
