Description

Technical Field

[0001] The invention relates to a water hammer powered liquid lifting and oxygenation device, belonging to the technical field of mechanical power equipment, in particular to the technical field of a water hammer powered liquid lifting and oxygenation device utilizing the flow and pressure of the liquid itself. Background Art

[0002] The widespread use of electric pumps in industry and agriculture has brought convenience and high efficiency to people in transporting liquids, but it has also brought about problems such as huge energy consumption and high operating costs.

[0003] People discovered the water hammer effect and invented the water hammer pump very early. Figure 8 As shown: A water hammer pump is a water-lifting device that uses water flow as power and produces a water hammer effect through mechanical action to lift water from a low place to a high place. Its structure mainly includes a pump body, a pressure relief valve, a water production valve, and a buffer tank. The pressure relief valve and the water production valve are both one-way valves. When started, the pressure relief valve is in an open state and the water production valve is in a closed state. The position of the water hammer pump is at least one meter lower than the water surface of the pool. One end of the water inlet pipe is connected to the pool, and the other end is connected to the liquid inlet of the water hammer pump. The water in the pool flows into the pump body of the water hammer pump through the water inlet pipe. When the water flows to the position of the pressure relief valve, the impact of the water flow causes the pressure relief valve to close quickly, and the water suddenly stops flowing. The kinetic energy of the water flow is converted into pressure energy, so the pressure in the pump body increases, which opens the water production valve. The position of the liquid outlet is between the buffer tank and the water production valve, and is connected to the water production pipe. Part of the water enters the buffer tank and rises along the water production pipe and flows out. Subsequently, due to the decrease in pressure in the water inlet pipe and the pump body, the pressure relief valve returns to the open state. At the same time, the pressure in the buffer tank increases, causing the water production valve to close. Water flows into the pump body from the water inlet pipe again. The pressure relief valve is closed again due to the impact of the water, and the whole process is repeated.

[0004] Although the water hammer pump does not require electricity and fuel during operation and has the advantage of low operating costs, it must have flowing water with a height difference to operate. It cannot directly lift water like an electric centrifugal pump. In addition, a large amount of water overflows from the pressure relief valve during the operation of the water hammer pump, which on the one hand causes a waste of the transported liquid, that is, water. On the other hand, in many cases, this water cannot be stored and placed. All of these limit the application of the water hammer pump. Summary of the invention

[0032] The principle and operation process of the water hammer powered liquid lifting and oxygenation device of the present invention are described in detail below with reference to the accompanying drawings:

[0033] Embodiment 1

[0034] Start-up and operation of the single-stage circulation lifting operation of the water hammer powered liquid lifting and oxygenation device of the present invention:

[0035] like Figure 1 , Figure 3 As shown: when the water hammer powered liquid lifting and oxygenation device of the present invention is started, liquid is first injected into the single-stage raw liquid tank, and the inlet valve at the liquid inlet of the water hammer pump is opened. The liquid used in the operation of this embodiment is water. When the liquid level of the water in the single-stage raw liquid tank reaches two-thirds of the height of the tank body, the valve disc of the water hammer pump pressure relief valve is pressed by hand, and it is pressed repeatedly several times, or the start-stop mechanism is started until the water hammer pump has a regular water hammer phenomenon, and the water in the pump body enters the buffer tank through the water production valve, and then enters the liquid storage tank set at a high place through the bracket through the liquid production pipe; during the operation of the water hammer pump, the water overflowing from the pressure relief valve falls into the overflow liquid tank, and then flows into the liquid receiving tank through the liquid receiving pipe. When the water level in the liquid receiving tank reaches two-thirds of the height of the tank body, the liquid level meter issues a high liquid level alarm prompt, and then the circulation pump is started to lift the water in the liquid receiving tank to the tank body of the single-stage raw liquid tank or the liquid storage tank, so that no water loss and waste occurs during the operation of the water hammer pump.

[0036] Embodiment 2

[0037] The startup and operation of the multi-stage circulation lifting operation of the water hammer powered liquid lifting and oxygenation device of the present invention:

[0038] like Figure 2 , Figure 3As shown: when the water hammer powered liquid lifting and oxygenation device of the present invention is started, liquid is first injected into the uppermost tank of the multi-stage raw liquid tank, and the inlet valve at the liquid inlet of the water hammer pump is opened. The liquid used in the operation of this embodiment is water. When the liquid level of the water in the uppermost tank reaches two-thirds of the height of the tank, the valve disc of the water hammer pump pressure relief valve connected to the uppermost tank is pressed by hand, and pressed repeatedly for several times, or the start-stop mechanism is started, until the water hammer pump has regular water hammer phenomenon, the water in the pump body enters the buffer tank through the water production valve, and then enters the high liquid storage tank through the liquid production pipe; during the operation of the water hammer pump, the water overflowing from the pressure relief valve falls into the overflow liquid tank, and then flows into the tank of the second multi-stage raw liquid tank from the top to the bottom through the liquid receiving pipe. When the water in the second tank When the water level reaches two-thirds of the height of the box body, press the valve disc of the water hammer pump pressure relief valve connected to the second box body with your hand, press it repeatedly several times, or start the start-stop mechanism, until the water hammer pump has regular water hammer phenomenon, and the water in the pump body enters the buffer tank through the water production valve, and then enters the high liquid storage tank through the liquid production pipe; repeat the above operation until the lowest water hammer pump starts to run, and the water overflowing from the water hammer pump pressure relief valve falls into the overflow liquid tank, and then flows into the liquid collecting tank through the liquid collecting pipe. When the water level in the liquid collecting tank reaches two-thirds of the height of the box body, the liquid level gauge issues a high liquid level alarm prompt. At this time, start the circulation pump to lift the water in the liquid collecting tank to the top box of the multi-stage raw liquid tank or the liquid storage tank, so that no water is lost or wasted during the operation of the water hammer pump.

[0039] The water hammer powered liquid lifting and oxygenation device of the present invention is arranged at a position below the water surface beside a river or a pool, and water is introduced into the raw liquid tank, so that the device can be operated. Usually, the ratio of the water produced by the water hammer pump to the overflow water of the pressure relief valve is affected by the water inlet height, the water produced lifting height and the structure of the water hammer pump itself. Taking the ratio of the produced water to the overflow water as 1:1 as an example, in the operation of the single-stage circulation lifting structure of the water hammer powered liquid lifting and oxygenation device of the present invention, about 50% of the water will overflow from the pressure relief valve. The water is recycled or lifted out through the collection of the liquid collecting tank and the lifting of the circulating pump, so that no water waves are generated during the operation. Compared with the use of centrifugal pumps, 50% of electric energy can be saved under the condition of the same water lifting volume; and in the operation of the multi-stage circulation lifting structure of the water hammer powered liquid lifting and oxygenation device of the present invention, the water overflowing from the pressure relief valve is collected and utilized for many times. For example, after 6 to 7 stages of circulation lifting, when it reaches the liquid collection tank, it has only about 7% to 20% of the initial water. Compared with the use of centrifugal pumps, under the condition of the same water lifting volume, the electric energy can be saved up to about 80% to 90%, so that the operation efficiency is greatly improved, the electricity consumption is further reduced, and the purpose of not wasting the transported liquid and reducing the operation cost is achieved.

[0040] Embodiment 3

[0041] The start and stop operation of the start and stop mechanism of the water hammer powered liquid lifting and oxygenation device of the present invention:

[0042] Start-stop mechanism, such as Figure 3 As shown: the start and stop operation of the water hammer pump can be electrically controlled. When starting, the motor of the starter drives the reducer to rotate, and the reducer drives the transmission mechanism. The transmission mechanism is usually a crank connecting rod or a cam. The transmission mechanism drives the guide rod to make vertical reciprocating motion along the cylinder. When the lower end of the guide rod touches the valve disc of the pressure relief valve, it continues to press down to open the pressure relief valve. Then the motor drives the guide rod to move upward to separate the guide rod from the pressure relief valve. At this time, a water hammer effect is generated in the water hammer pump, and the impact force of the water closes the pressure relief valve. When the shaft of the reducer rotates one After a week, the guide rod is driven downward again to open the pressure relief valve again. After multiple vertical reciprocating movements for 5 to 10 seconds, a stable water hammer effect is formed, and the starter needs to be stopped to make the water hammer pump operate by relying on the water hammer effect. At this time, the upper part of the guide rod touches the limit switch to turn off the power supply of the motor and stop the guide rod at the highest point of operation, so that the guide rod no longer applies pressure to the valve disc of the pressure relief valve, allowing the water hammer pump to operate normally. When the water hammer pump needs to stop running, the water inlet can be stopped by closing the inlet valve at the liquid inlet of the water hammer pump.

[0043] Embodiment 4

[0044] The operation process of the oxygenation operation of the water hammer powered liquid lifting and oxygenation device of the present invention is as follows:

[0045] like Figure 4 , Figure 5 , Figure 6 As shown: the liquid used during the operation of this embodiment is water. The main spray pipe of the oxygenation mechanism is set at a position higher than the water surface of the oxygenation pool through a bracket. The main spray pipe is connected to the liquid outlet pipe of the storage tank. The water in the storage tank flows out along the through holes of the main spray pipe or the sub-spray pipe and falls into the oxygenation pool, or first falls onto the nozzle and then falls from the nozzle. In the process of water falling, the water contacts with the air, the oxygen in the air is dissolved into the water, and the water falls into the oxygenation pool again. At the same time, the main liquid outlet pipe is connected to the liquid outlet pipe of the storage tank, and the water in the storage tank flows along the main liquid outlet pipe, and flows out from the through hole on the main liquid outlet pipe or the branch liquid outlet pipe to the aeration tank, stirring the water in the aeration tank or the aerobic microorganisms in the water, and the aerobic microorganisms are fully in contact with the falling water, thereby achieving the effect of supplementing oxygen to the water in the aeration tank; or the water falling from the spray assembly falls into the shower liquid collecting tank, is collected by the shower liquid collecting tank, and then flows out to the aeration tank through the through hole on the main liquid outlet pipe or the branch liquid outlet pipe, so that the water containing dissolved oxygen can enter the bottom of the aeration tank, which can increase the time that the dissolved oxygen stays in the water body.

[0046] The water hammer powered liquid lifting and oxygenation device of the present invention can be used for aerobic processes in sewage treatment to oxygenate water bodies, and can also be used to oxygenate water in fish and shrimp ponds in the aquaculture industry. Compared with traditional aeration and oxygenation using fans, the operating cost is greatly reduced.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
