It removes suspended colloids, cellulose, protein, leftover bait, feces and other organic matter in the source water through flotation.

[0003] A patent document in China with application number 201911209410.6 and publication date 2020.3.6 discloses a protein skimmer for marine aquaculture, comprising a reaction cylinder provided with an inner cavity, the top of the reaction cylinder is connected to a bubble collector for collecting foam in the reaction cylinder; the top of the bubble collector is connected to a foam collection tube; the lower part of the reaction cylinder is connected to a plurality of venturi ejectors; the water inlet end of the venturi ejector is connected to a three-way water inlet pipeline; one way of the three-way water inlet pipeline is connected to the upper part of the reaction cylinder; the other way of the three-way water inlet pipeline is connected to a water inlet pump; a water outlet pipeline is provided at the bottom of the reaction cylinder; the venturi ejector generates bubbles to fully mix with the water body to absorb organic matter in the water body.

[0004] The Venturi ejector sprays a mixture of gas and liquid upward. In the separator, the mixture only interacts with the water body in a straight line, and the flow distance of the mixture in the reaction cylinder is short, resulting in a short contact time between the bubbles and the water body, and a poor adsorption effect on organic matter in the water body. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a protein separator, in which an arc-shaped flow channel is provided to extend the flow distance of the mixture and the contact time between the bubbles and the water body. At the same time, the input direction of the mixture is not in the same straight line as the arc-shaped flow channel. The mixture impacts the inner wall of the arc-shaped flow channel to form turbulence, increase the generation of bubbles, and enhance the adsorption effect on organic matter.

[0006] In order to solve the above technical problems, the technical solution used in the utility model is:

[0007] A protein separator comprises a cylinder, a collecting device is arranged above the cylinder, a water inlet pipe, a water pumping pipe and a water outlet pipe are connected to the cylinder, the water inlet pipe is used to input untreated liquid, the water outlet pipe is used to output treated liquid, a first jet component is arranged in the cylinder, the water pumping pipe is connected to the input end of the first jet component; an arc flow channel is arranged in the cylinder, the inlet of the arc flow channel is arranged opposite to the output end of the first jet component, and the outlet of the arc flow channel extends to the collecting device.

[0008] Preferably, the arc-shaped flow channel is provided with a first arc-shaped segment and a second arc-shaped segment, and the bending direction of the first arc-shaped segment is arranged opposite to the bending direction of the second arc-shaped segment.

[0009] Preferably, the first jet assembly includes more than one first ejectors, the number of the arc-shaped flow channels corresponds to the number of the first ejectors; the inlet of the arc-shaped flow channel is arranged opposite to the output end of the first ejector.

[0010] Preferably, the collecting device includes a collecting chamber and a sewage pipe, the sewage pipe is connected to the collecting chamber, and there is a collecting port in the collecting chamber, the collecting port extends from the bottom of the collecting chamber to the top of the collecting chamber, and the distance between the output end of the collecting port and the top of the collecting chamber is less than the height of the collecting port.

[0011] Preferably, two second ejectors are further provided on the arc flow channel, the arc flow channel is located between the two second ejectors, the second ejectors are arranged obliquely relative to the first ejectors, and the second ejectors are connected to the water pumping pipe.

[0012] Preferably, the output end of the second ejector is arranged toward the collecting port.

[0013] Preferably, guide plates are provided on both sides of the collecting port.

[0014] Preferably, the arc-shaped flow channel and the cylinder are detachably connected.

[0015] Compared with the prior art, the beneficial effects of the protein separator described in the utility model are mainly reflected in:

[0016] By setting an arc-shaped flow channel, and the inlet of the arc-shaped flow channel is arranged opposite to the output end of the first jet component, the gas and liquid mixture output by the first jet component drives the water body into the arc-shaped flow channel and flows along the arc-shaped flow channel, thereby extending the flow distance of the mixture, extending the contact time between the bubbles and the water body, and having a good adsorption effect on organic matter; at the same time, since the arc-shaped flow channel is set in an arc shape, and the mixture output by the first jet component moves in a straight line, the mixture will impact the inner wall surface of the arc-shaped flow channel when flowing, thereby increasing the generation of bubbles and improving the adsorption effect on organic matter.

[0017] The arc-shaped flow channel is provided with a first arc segment and a second arc segment, which further prolongs the length of the arc-shaped flow channel and further prolongs the contact time between the bubbles and the water body; at the same time, the bending direction of the first arc segment is arranged opposite to the bending direction of the second arc segment, so that the mixture has a first impact on the inner wall of the first arc segment and a second impact on the inner wall of the second arc segment, further increasing the generation of bubbles.

[0018] In the collecting device, the height of the collecting port is set to prevent the foam entering the collecting cavity from overflowing from the collecting port, and to prevent the foam in the collecting cavity from flowing back into the cylinder.

[0019] The second ejector is tilted, and the output end of the second ejector outputs the mixture in different directions from the output end of the first ejector, thereby increasing the distribution area of ​​the bubbles, increasing the contact area between the bubbles and the water body, and improving the adsorption effect on organic matter. At the same time, the output end of the second ejector faces the collection port, and under the action of the mixture output by the second ejector, the bubbles are pushed to the collection port, which is convenient for collecting the foam.

[0020] The utility model prolongs the flow distance of the mixture and the contact time between the bubbles and the water body by arranging an arc flow channel. At the same time, the input direction of the mixture is not in the same straight line as the arc flow channel. The mixture impacts the inner wall of the arc flow channel to form turbulence, increase the generation of bubbles, and enhance the adsorption effect on organic matter.
