A bubble-dispelling fish-suction pump

technical field

The utility model belongs to the technical field of fishing equipment, and relates to a fish-suction pump, in particular to a fish-suction pump for driving fish with air bubbles.

Background technique

At present, in aquaculture, especially in large-scale aquaculture ponds and large-scale deep-water cage base aquaculture, due to the increasing scale of aquaculture, the output of farmed fish is also increasing. Currently, a single large-scale deep-water cage can be aquaculture 10 to 50 tons of finished live fish. Therefore, when the fish is grown, the live fish must be harvested and sold quickly in order to ensure the economic benefits of farming. However, such a large number of finished live fish must be harvested and maintain a high survival rate. Because there is no suitable fast and efficient mechanized fish harvesting equipment, fish harvesting is a big problem. At present, only manual fish harvesting, or crane-type equipment and hanging baskets are used to collect fish. The speed is slow for a long time, and the mechanical damage to the fish is also great, resulting in high mortality of live fish, which will seriously affect the economic benefits of farming. Therefore, how to quickly and efficiently mechanize fish harvesting is an urgent need in the current large-scale aquaculture industry. solved puzzles.

Vacuum fish suction pump is mainly used for large-scale seine, trawl, and side lift net fishing fishing boats and fresh fish at sea, which can improve the fishing efficiency of ocean fishing, especially pelagic fishery, by more than 30%. Compared with other types of fish suction pumps, it has better suction It has the advantages of large height and small fish damage.

For a single-tank fish suction pump, every time it is full, it needs to stop vacuuming the tank to discharge the sucked fish. At this time, the vacuum pump is in an idling state, resulting in large wasteful power consumption and low efficiency. In addition, the ratio of fish to water (i.e. the ratio of solid to liquid) is also an important factor affecting the efficiency of fish suction. When the fish-water ratio is 1:1, the fish-absorbing efficiency is the highest, and as the ratio decreases, the fish-absorbing efficiency decreases greatly. When using the fish suction pump to suck the fish in the breeding net cage, since the size of the net cage cannot be changed, as the fish in the net cage becomes less and less, the ratio of fish to water becomes smaller and smaller, and the change of suction fish It is getting more and more difficult and inefficient.

When the fish reaches a certain density, open the solenoid valve 1, and the fish are sucked into the fish suction pipe, and the suction at the end of the fish suction pipe will also make the air curtain move toward the center. The ends of the fish suction pipes converge to form an inverted funnel-shaped air curtain in the water, which is more conducive to the suction of fish, and the efficiency of fish suction is higher.

In the above-mentioned air-bubble fish-dispelling and fish-suction pump, a casing is sleeved from the connection between the hose and the exhaust pipe to the ring. When the size of the hose ring is small, the sleeve can move along the hose. The function of the sleeve is to prevent the gas from leaking from the through hole in the non-circular part of the hose, so that the gas can flow to the entire ring part of the hose. discharge to ensure the efficiency of fish suction.

In the above-mentioned air-bubble fish-dispelling fish-suction pump, the tank body is arranged obliquely and the end portion provided with the fish discharge pipe is at a relatively low position. The tank body is inclined to facilitate the discharge of fish and water in the tank body.

In the above-mentioned air-bubble fish-dispelling fish-suction pump, the fish discharge pipe is also provided with a solenoid valve 3 capable of controlling the connection or disconnection of the fish discharge pipe with the tank body.

Compared with the prior art, the bubble-dispelling fish-suction pump has the following advantages: the gas discharged by the vacuum pump is used to generate an air curtain in the net cage, thereby controlling the fish in the space surrounded by the air curtain to improve the fish-suction efficiency, and at the same time The exhaust of the vacuum pump is used to improve the working efficiency of the pump.
