Description

Detachable centrifugal assembly for aquaculture Technical Field The utility model belongs to the technical field of aquaculture, and particularly relates to a detachable centrifugal assembly for aquaculture. Background In the existing fishery production, solid-liquid separation is often required for the water body in the fishery cultivation process. In the cultivation process, the cultivation water contains solid impurities such as feed residues, excrement and the like. If not removed in time, the solid impurities can influence and pollute the water environment and even cause harm to the health of the cultured organisms. For the removal of solid waste, the common equipment is a centrifugal filter, the centrifugal filter utilizes the centrifugal force generated by high-speed rotation to enable the liquid containing solid impurities to be thrown to the inner wall of the filter under the action of the centrifugal force, the purified liquid flows out through a filter screen, the trapped solid waste is discharged from the bottom of the filter screen under the action of the centrifugal force, so that the solid waste and the liquid in the cultivation tail water can be effectively separated, the pollutants in the cultivation waste water are removed by rapid separation, and the filtration efficiency is improved. The centrifugal filter is widely applied in the field of aquaculture, not only improves the cultivation efficiency, but also is beneficial to environmental protection and sustainable utilization of resources. Nevertheless, the existing centrifugal filter still has the following defects that (1) the energy consumption is high, high-power driving is required for high-speed rotation, the working principle of the centrifugal filter is that the centrifugal force generated by high-speed rotation is relied on to realize solid-liquid separation, and a high-power motor is required to be equipped to drive the rotary drum to rotate, so that the energy consumption is high. In areas where energy supply is intense or electricity costs are high, this may increase the cost of fishery farming. (2) The continuous operation has high energy consumption, and in order to ensure the filtering effect and the continuity of water quality treatment, the centrifugal filter needs to continuously operate for a long time, which also consumes a great amount of electric energy (3) the components which are easy to wear, such as a rotary drum, a bearing, a sealing ring and the like in the centrifugal filter are easy to wear in the process of high-speed rotation and long-term use, and the components need to be replaced periodically, so that the maintenance cost of equipment is increased. (4) The cleaning difficulty is high, dirt and impurities are easy to accumulate in the filter, and the filter needs to be cleaned regularly. However, the cleaning process is relatively complicated due to the complicated structure, and thus requires much time and labor. For example, some centrifugal filters have a narrow bowl interior, which is difficult for cleaning tools to access, resulting in incomplete cleaning. Disclosure of utility model In order to solve the technical problems, the utility model provides a detachable centrifugal component for aquaculture, which is detachable, movable and high in compatibility, can be placed in different use scenes according to the requirements of users, flows the pressurized aquaculture wastewater into the inner side of a centrifugal filter in a 45-degree direction, forms high-pressure column water flow to drive a stainless steel 316 filter screen to rotate to form centrifugal force, realizes solid-liquid separation, and flows the filtered purified water back to a culture pond or a biochemical pond for the next treatment process. The parts which are easy to wear can be independently disassembled and replaced, the filter is not required to be integrally replaced, and the maintenance cost and the downtime of equipment are reduced. The technical scheme disclosed by the utility model is as follows: The utility model provides an aquaculture is with detachable centrifugation subassembly, includes bearing frame, interior bearing frame, two bear frame, filter screen, goes up strutting arrangement, lower strutting arrangement, mounting, and the bearing frame is connected at the mounting top, and strutting arrangement is gone up in the bottom connection, and the filter screen can be dismantled and fix between strutting arrangement and lower strutting arrangement, and the upside is cylindrical, and the downside is conical, and the bottom is even has the sewer pipe, and the sewer pipe passes lower strutting arrangement to can rotate in lower strutting arrangement. The inner bearing seat is in a ring shape, the two bearing frames are connected to two sides of the inner bearing seat, the fixing piece penetrates through the inner bearing seat, the bearing seat is clamped on the inner bearing seat, the fixing piece, the filter screen,
