The to-be-solved technical problem of the utility model is to provide an industrial recirculating aquaculture uses energy-conserving microstrainer that filter area is big, filtration efficiency is high, the cylinder is small equipment cost low, it is low to need not motor drive energy consumption, the power consumption is with low costs, the high filter screen of filter fineness is not restricted, the filter effect is good, convenient to use is nimble.

SUMMERY OF THE UTILITY MODEL

For solving above-mentioned prior art filter area is little, the huge equipment cost of cylinder is high, filtration efficiency is low, motor drive cylinder filters the energy consumption higher, the power consumption is with high costs, filter fineness is limited, can only adopt not more than 120 meshes, filter screen, filter effect not good, use trouble limited scheduling problem, the utility model discloses a following technical scheme:

the utility model provides an energy-saving micro-filter for industrial recirculating aquaculture, which comprises a supporting frame, a filtering roller, a water passing rotating shaft, a back-flushing pump, a back-flushing pipe, a plurality of spray heads and a collecting tank, wherein the filtering roller is erected in the supporting frame, the outer surface of the filtering roller is covered with a plastic framework, the plastic framework is wrapped with a filter screen, a plurality of rows of fish fin-shaped bulges are arranged in the filtering roller, the water passing rotating shaft is arranged in the filtering roller in a penetrating way, the hinging part of the filtering roller and the nylon bearing is arranged at the hinging part of the filtering roller, the water passing rotating shaft is provided with a plurality of water outlet holes, the two ends of the water passing rotating shaft are respectively provided with a water inlet and a water outlet, the back-flushing pipe is erected at the top of the supporting frame, the plurality of spray heads are arranged on the back-flushing pipe and face the filtering roller, the back-flushing pump is respectively communicated with an external water tank and the back-flushing pipe, the collecting tank is fixedly arranged on the water passing rotating shaft, and one end of the water passing rotating shaft is connected with a sewage outlet, the water outlet is connected with a drain pipe, and the drain outlet is connected with a drain pipe.

As an improvement, the drain pipe and the blow-off pipe are both provided with valves (8).

As right the utility model discloses a further improvement, the braced frame material is plastics or metal, the filter cylinder material is PP or PVC, it is PVC or stainless steel to cross the water pivot material.

The beneficial effects of the utility model reside in that: adopt rivers drive cylinder to rotate and filter, whole stack shell is all filtering, and the big filtration efficiency of filter area is high, and the small equipment cost of cylinder is low, and it is low to need not motor drive energy consumption, and the power consumption is with low costs, and the cylinder is difficult for blockking up in the motion all the time, does not have the requirement to the filter screen and uses more nimble convenience.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, an energy-saving micro-filter for industrial recirculating aquaculture comprises a support frame 1, a filter drum 2, a water passing rotary shaft 3, a back washing pump 4, a back washing pipe 5, a plurality of spray heads 6 and a collecting tank 7, wherein the filter drum 2 is erected in the support frame 1, the outer surface of the filter drum 2 is coated with a plastic skeleton, the plastic skeleton is coated with a filter screen, a plurality of rows of fin-shaped protrusions 21 are arranged in the filter drum 2, the water passing rotary shaft 3 is arranged in the filter drum 2 in a penetrating manner, a nylon bearing 31 is arranged at the hinged position of the water passing rotary shaft 3 and the filter drum to reduce sliding friction between the water passing rotary shaft and the filter drum, a plurality of water outlet holes 32 are arranged on the water passing rotary shaft 3, a water inlet 33 and a water outlet 34 are respectively arranged at two ends of the water passing rotary shaft, the back washing pipe 5 is erected at the top of the support frame 1, the spray heads 6 are arranged on the back washing pipe 5 and face the filter drum 2, the backwashing pump 4 is respectively communicated with an external water tank and a backwashing pipe 5, the collecting tank 7 is fixedly arranged on the water passing rotating shaft 3, one end of the collecting tank is connected with a drain outlet 71, the water outlet 34 is connected with a drain pipe 35, the drain outlet 71 is connected with a drain pipe 72, the drain pipe 35 and the drain pipe 72 are both provided with valves 8, when in filtering, the two valves are both in a closed state, the filtered water enters the water passing rotating shaft from the water inlet and flows out through the water outlet, the effluent freely falls down to impact the bulge to generate downward impact force to drive the filtering roller to rotate, the water flows to the lower part of the roller and freely filters and flows out of the roller by gravity, and the particulate matters are remained in the roller, thus the filtering can be realized, the roller is always in rotation, the filtering net is not easy to be blocked, the permeability of the roller is reduced along with the increase of the particulate matters in the roller, the internal water level is increased, and the water level in the roller exceeds a certain height, the backwashing is started, a high-pressure water pump and a high-pressure nozzle are matched for backwashing, a timing opening or water level probe is adopted, water of an external water tank is pumped into the pipe through a water pump and then sprayed out through the nozzle, the nozzle is aligned with the roller to perform backwashing, sewage after backwashing flows into the open collecting tank, the valve of the sewage discharge pipe is opened, the sewage flows out from the sewage discharge port, and when excessive water in the roller is found, the valve of the water outlet is opened to discharge the water.
