A 産業上の利用分野
この発明は、魚を水と一緒に搬送するプレードレス式の
魚ポンプに関し、特に運転中にプレードレスインベラ内
の空気が吸出できる旨吸菱贋を備えた魚ポンプに関する
。DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application This invention relates to a plaidless type fish pump for conveying fish together with water, and particularly to a suction pump that can suck out the air inside the plaidless inflator during operation. Concerning fish pumps with counterfeits.
B 従来の技術
螺旋状の流路を有するプレードレスィンベラのポンプは
、魚ポンプとして使用されている。B. PRIOR TECHNOLOGY Plaidless sinker pumps with helical flow channels are used as fish pumps.
このポンプが魚ポンプに多用される理由は、小型で時間
当りの移送能力が大きい為である。この魚ポンプは、通
常の運転状態にあっては、魚をほとんど損傷させること
なく移送できる。The reason why this pump is often used as a fish pump is because it is small and has a large transfer capacity per hour. Under normal operating conditions, this fish pump can transport fish with little damage.
しかしながら、空気を吸入して空転すると魚を著しく損

シング1の上端に空気抜管2が連結されたものが開発さ
れた。However, it has the disadvantage that if it sucks in air and spins idly, it can seriously damage the fish. This drawback severely limits the use of this type of fish pump. Furthermore, once it started idling, self-priming was extremely difficult, so it was mostly used as a submersible pump. As a self-priming device for this plaidless type fish pump, one was developed in which an air vent pipe 2 was connected to the upper end of a casing 1 of the fish pump, as shown in FIGS. 1 and 2.

と、第2図に示すように、ィンベラ内の中央部が空気で
満たされ、水は回転するインベラの遠心力によってケー
シングの内周に沿うので、空気抜管からは水だけが排出
されてィンベラ内の空気が排出されない。To operate a self-priming culvert with this structure, first stop the operation of the fish pump, remove the air from the pump and suction pipe 3 through the air vent pipe 2, and fill the suction pipe 3 and the fish pump with water. After that, the fish pump was started and the water and fish were removed. however,
A self-priming device with this structure is designed to operate as shown in Figure 2 once air is sucked into the fish pump due to some reason, such as air remaining in the suction pipe or the suction pipe sucking in some air. As such, the central part of the invera is filled with air, and water is drawn along the inner circumference of the casing by the centrifugal force of the rotating invera, so only water is discharged from the air vent pipe and no air inside the invera is exhausted.
この状態で、空気抜管から多少の水を吸引しても、吸い
出す水と同量の水が吸入管の底に伝わってチョロチョロ
と魚ポンプに流れ込み、しかもこの水が回転するィンベ
ラによってケーシングの内周面にふり出されて空気抜管
と送出管から排出されるので、ィンベラ内の空気はほと
んど排出できない。In this state, even if some water is sucked from the air vent pipe, the same amount of water as sucked out will be transmitted to the bottom of the suction pipe and trickle into the fish pump, and this water will be transferred to the inner periphery of the casing by the rotating inflator. Since the air is blown out to the surface and discharged from the air vent pipe and delivery pipe, almost no air inside the invera can be discharged.
よって、この構造の魚ポンプは、魚ポンプ内に空気が吸
入されると、一旦魚ポンプの運転を停止しなければ、魚
ポンプ内の空気を排出できず、運転しながら自吸できな
い欠点があった。Therefore, a fish pump with this structure has the drawback that once air is sucked into the fish pump, the air inside the fish pump cannot be discharged unless the operation of the fish pump is stopped, and the fish pump cannot self-prime while operating. Ta.
この欠点は魚ポンプにとって極めて重要である。This drawback is extremely important for fish pumps.

用途を制限した。更に、魚ポンプの主たる用途は、網で
捕獲した魚を魚槽に搬入すると共に、魚槽から搬出する
ものである。This is because, unlike pumps that only transport water, fish pumps transport fragile fish, so if a fish is transported that is even slightly damaged during transport, the performance of the fish pump and the product may be affected. The value will be significantly reduced and, to make matters worse, the fish pump will suffer the most damage if the fish are left spinning inside the invera. Therefore, as with conventional fish pumps, if air is sucked in during operation and the fish pump no longer transports water and fish, the fish inside the pump will be seriously damaged. This drawback has limited the applications of fish pumps. Furthermore, the main use of the fish pump is to transport fish caught with a net into a fish tank and to transport them out of the fish tank.

るいは魚槽内に入れて魚と水とを吸入する為、使用途中
の頻繁な空気吸入を阻止できない。If a large amount of fish cannot be brought in from the net in a short period of time, the fish will suffocate and die, the value of the product will be completely destroyed, and in the worst case scenario, the net will be damaged. Therefore, it is particularly important to increase the fish pump's ability to transport fish quickly, that is, to increase its transport capacity per hour. Furthermore, fish pumps are rarely installed with complete suction pipes like regular water pumps, but instead a flexible hose is connected to the suction side. Since the device is placed in a net under the sea or in a fish tank to inhale fish and water, it is not possible to prevent air from being frequently inhaled during use.
例えば魚槽から魚水を排出する場合、魚槽内の魚水が少
なくなれば必ずといってよい程一時的に空気を吸入する
。For example, when draining fish water from a fish tank, air is almost always temporarily sucked in when the fish water in the tank becomes low.

縮する魚ポンプを提供するにある。Therefore, even though fish pumps have the characteristic that self-priming is difficult in principle compared to ordinary water pumps, they must self-prime while operating, and furthermore, the main suction time is shortened as much as possible. Must. In order to shorten the suction time,
A vacuum pump connected to the suction side of the fish pump must be able to quickly evacuate the air inside the fish pump. For this purpose, it is necessary to eliminate the adverse effects that fish transferred with water or scales peeled off from fish have on the exhaust action of the vacuum pump. Fish and scales can be prevented from being sucked into the vacuum pump by connecting a filter to the suction side of the vacuum pump. Smooth evacuation of air over a long period of time is not satisfactory. C. Purpose of the Invention The present invention provides that each time the self-priming action is completed, foreign substances such as fish and scales adsorbed to the filter are removed and washed away, thereby preventing the filter from clogging for a long time. To provide a fish pump in which a vacuum pump smoothly exhausts air inside the fish pump to shorten suction time.

ましく実施例
以下、本発明の一実施例を図面に基づいて説明する。However, the fish pump of the present invention is configured so that the deposits on the filter surface are forcibly washed away with transferred water every time the fish pump completes self-priming. Therefore, even if the transferred water carries fish that are adsorbed to the filter, or contains a large amount of foreign matter such as scales, this will not accumulate on the filter and obstruct the air exhaust of the vacuum pump, and the filter will not In the evening, it is always cleaned cleanly, and the vacuum pump smoothly sucks out air from the suction pipe. In other words, the fish pump of the present invention minimizes the idling time that causes significant damage to fish, thereby reducing damage to fish.
The self-priming time is shortened, the transfer efficiency is substantially improved, and even a large amount of fish caught in silk can be sucked up in a short period of time, making it ideal for a fish pump. F Preferred Embodiment Hereinafter, one embodiment of the present invention will be described based on the drawings.

されている。Therefore, the rotating shaft of the invera is connected to the motor 9.
Further, a delivery pipe 12 is connected to the delivery port 10 of the fish pump via a foot valve 11, which is a check valve, to prevent water from flowing back. FIG. 4 shows the fish pump 16 vertically disposed with the suction port facing upward, and the suction pipe 17 connected above the suction port. If the fish pump is installed in this way, the air inside the fish pump can be completely exhausted using the vacuum pump before starting the fish pump, so after removing the air from the fish pump using the vacuum pump, Simultaneously with pump operation, the fish pump starts transporting water. Therefore, the startup time is extremely shortened. In FIG. 3, the suction pipe 6 is a vertically piped structure with the vicinity of the fish pump 4 facing upward in the opposite direction to the water transfer direction, that is, facing downward toward the suction port 5. The height of the raised part of the bracket is at least twice as high as the inner diameter of the suction port 5.

。However, the rising part of this suction pipe does not necessarily have to be installed vertically, and can be inclined to the extent that air from the fish pump in operation is exhausted and water is injected in place of the air.
The rising part of the suction pipe reduces the self-priming time of the fish pump. This is because when the air flows back to the suction side from the idling fish pump and the air is exhausted, the transferred water in the rising section flows into the fish pump. The higher the rising part is, the more forcefully the water in the rising part flows into the fish pump, and the more effective the rising part is. If the upright part is separated from the fish pump for a long time, the water in the upright part will not flow into the fish pump as forcefully, and the self-priming time of the fish pump will become long.
従って、本発明は、立上部を魚ポンプの近傍に特定して

いて水を送り込む為のものである。Therefore, the present invention specifies the riser in the vicinity of the fish pump. However, if the rising part is high, the self-priming time can be shortened even if it is a little far from the fish pump. Therefore, in this specification, it goes without saying that the vicinity in which the rising part is provided near the fish pump means a distance at which the effect of the rising part can be expected. Also, installing the suction pipe vertically near the fish pump is not for effectively discharging the air in the suction pipe, but for pumping water by removing air from the center of the fish pump's inflator during operation. It is something.

。As shown in FIG. 3, the end of the suction pipe may be installed higher than the point where the air vent pipe is connected. The air vent pipe is connected to the third pipe so that air accumulated in the center of the fish pump can be removed during operation.
The figure is attached to the top. In other words, there is no need to connect the air vent valve to the highest point of the piping, as shown in Figure 3, as shown in Figure 3, where a part of the suction pipe connects the air vent pipe and the suction pipe. It may be located above. FIG. 5 shows a preferred embodiment of connecting the air vent tube to the suction tube.

内の魚が吸入されない。In FIG. 5, an air vent pipe 15 is vertically connected to the upper surface of the suction pipe 13 in the shape of a pipe through a filter 14, and the air vent pipe 15 is divided into two parts by a cheese and has a one-way opening/closing valve 16. However, the other end is connected to a vacuum pump via a check valve 17. The on-off valve 16 is opened to drain water from the suction pipe 13 and the fish pump, and the check valve 17 has the function of preventing air from flowing back into the suction pipe. As shown in Figure 5, air vent pipe 1
5 is closed with a member such as the filter 14 through which only fluid can pass, so that fish in the suction pipe are not sucked into the air vent pipe 15.

最適である。As the vacuum pump, any pump that can bleed air can be used, but a flexible rotor pump or Natsch type vacuum pump that can suck out water and air, for example, is optimal.
本発明の鷺ポンプは、運転状態に於て、魚ポンプ内の空
気が排気される。When the heron pump of the present invention is in operation, the air inside the fish pump is exhausted.

転状態は、まず真空ポンプ8で吸入管6の空気を排出す
る。A rotating bladeless inflator creates an air pocket in the center. As mentioned above, this air pocket flows into the suction pipe from the suction port of the fish pump and is floated and exhausted. In the operating state of the fish pump eye suction device configured as described above, air from the suction pipe 6 is first discharged by the vacuum pump 8.

運転される自吸運転時に、吸入管6は、吸入される水が
動いたり止つたりしながら自吸作用が完了する。At this time, the fish pump 4 is stopped, so some air remains in the upper part of the casing of the fish pump 4, but when the fish pump 4 starts operating, the water inside the fish pump 4 is pumped into the casing by centrifugal force. The light air at the top of the casing gathers in the center of the invera. This central air flows back into the suction pipe 6 and is discharged from the air vent pipe 7, and the fish pump 4 starts suctioning water. If the suction pipe 6 sucks air while sucking water, the fish pump 4 will accumulate air in the center of the invera and stop conveying water. However, the air in the center of the invera flows back into the suction pipe 6 and is discharged from the air vent pipe 7, and instead of the air, water flows into the invera from the rising part of the suction pipe 6, so the center of the invera is filled with water again. The fish pump 4, which has been flushed with water, starts transporting water. During the self-priming operation in which both the fish pump 4 and the vacuum pump 8 are operated, the suction pipe 6 completes its self-priming action while the suctioned water moves and stops.

強制的に洗浄される過程は次の通りである。That is, when the air pocket is sucked into the fish pump 4, the movement of water is temporarily stopped, and the vacuum pump 8 causes the fish pump 4 to stop moving.
When the air is exhausted from the tank, the process of water movement repeats again. During this process, the filter 14 on the suction side of the vacuum pump 8
Fish, scales, etc. are adsorbed to it. If fish, scales, etc. adsorbed by the filter 14 are not removed and gradually accumulate in large quantities, the air exhaust capacity of the vacuum pump 8 decreases, the self-priming time becomes longer, or the self-priming action is lost. be exposed. The process in which the filter 14 of the fish pump shown in FIG. 3 is forcibly cleaned with the suction and transfer water of the fish pump 4 is as follows.
■ 魚ポンプ4に多量の空気が吸入されて、ポンプ機能

送させる。(2) When a large amount of air is sucked into the fish pump 4 and the pump function is stopped, the air mass at the center of the fish pump flows back into the suction pipe 6, passes through the filter 14, and is exhausted to the vacuum pump 8.
■ By exhausting air from filter 14,
The water level in the suction pipe 6 rises, and water is sucked out through the filter 14. In this state, fish, scales, etc. mixed into the L water are adsorbed by the filter 14. ■ At this moment, the fish pump 4 enters normal water suction operation, so it sucks in a large amount of water through the suction pipe 6, washes away fish and scales that have adhered to the filter 14, and mixes the fish and scales with the water into the fish pump 4. Inhale and transfer to the inside.

せず、魚はフィル夕14に吸着されない。When the fish pump 4 starts normal operation, the vacuum pump 8 sucks water instead of air. Vacuum pump 8 for air evacuation
Since it is designed for use with air, its drainage capacity is low and its ability to attract fish and scales is reduced, making it easier for them to be removed. ■ When the air spirit is sucked into the fish pump 4 again,
Although the fish pump 4 loses its pumping function, when air is passing through the filter 14, water does not assist the filter 14 and fish are not attracted to the filter 14.

吸を完了できる。Immediately after the fish are adsorbed to the filter 14, the fish pump 4 starts normal operation, and clogging of the filter 14 is effectively prevented. Therefore, there is no need to frequently disassemble and clean the filter 14, and the vacuum pump can always complete self-priming in the shortest possible time.
