Problems solved by technology

At this stage, the tail water of aquaculture mostly adopts multi-stage sedimentation, filtration and biological treatment, which requires a large-scale transformation of the aquaculture pond. The tail water treatment cycle is long, and there is no very effective solution for the fixation and transfer of solid waste; The filter press equipment commonly used in industrial production often needs to add chemical flocculants during the sedimentation stage. The addition of chemical agents is strictly prohibited by aquaculture, and the filter press without flocculants has a poor effect and cannot effectively fix solid waste. and transfer

Abstract

The invention discloses an aquaculture waste centrifugal filter pressing device and a control method thereof. The aquaculture waste centrifugal filter pressing device comprises a motor bin, a centrifugal cylinder and a filter pressing cover which are arranged on an installation support, and the motor bin and the filter pressing cover are arranged at the two ends of the centrifugal cylinder respectively and connected with the centrifugal cylinder in a sealed mode. Compared with the prior art, the device and the control method disclosed by the invention have the following advantages that (1) thedevice and the control method comprehensively utilize centrifugal dehydration and filter pressing fixation, so that effective solid-liquid separation and solidification transfer of aquaculture wastescan be effectively realized; (2) according to the device and the method, a direct-current high-speed motor is used for driving the centrifugal cylinder to throw away most of water, purified water isdischarged back, the filter pressing efficiency is effectively improved, and the solidification transfer difficulty is reduced; and (3) the device is simple to install, and the operation method is intelligent and easy to learn.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to an aquaculture tail water treatment device, in particular to a centrifugal filter press device for aquaculture waste and a control method thereof. Background technique [0002] In recent years, aquaculture tail water treatment equipment and related technologies have been widely promoted and applied, but traditional physical or biological treatment methods have a long cycle and generally require corresponding pond reconstruction, which has brought huge obstacles to the promotion and practical application of related technologies , it is very urgent to design and develop a kind of equipment and facilities that can realize the solid-liquid separation of aquaculture waste. At this stage, the tail water of aquaculture mostly adopts multi-stage sedimentation, filtration and biological treatment, which requires a large-scale transformation of the aquaculture pond. The tail water treatm...
