Technical Field

[0001] The utility model belongs to the technical field of axial flow fan sealing, and particularly relates to a water supply and return device for a water curtain wall without a water pool. Background Art

[0002] With the rapid development of social economy, there are more and more greenhouses, sheds, livestock houses, workshops and factories. At present, in large-area places such as greenhouses, sheds, livestock houses, workshops and factories, when the climate is hot, a cooling fan needs to be used for cooling.

[0003] In the prior art, a water curtain fan is usually used as a cooling device for large-area places such as greenhouses, sheds, livestock houses, workshops and factories. The main component of the water curtain fan is the water curtain body. Condensed water in the water curtain pool is transported to the upper part of the water curtain body by a water pump, and then immerses into the water curtain body from top to bottom. The excess condensed water after immersion returns to the water curtain pool through the circulation pipeline below the water curtain body to form a water cycle; then through a negative pressure fan, the hot air outside the water curtain body is turned into cold air through the gaps in the water curtain body and enters the room, so as to achieve the purpose of cooling.

[0004] The prior art has at least the following problems:

[0005] 1. Since the water curtain body needs continuous water circulation, a water curtain pool must be equipped. At present, most water curtain pools are made of concrete pouring or customized finished water tanks, which are costly and inconvenient to maintain. Especially after each year of shutdown, it is necessary to clean them to prevent the growth of moss and blockage of pipelines.

[0006] 2. The water curtain is for evaporative cooling, and generally the circulating water volume of the water curtain pool is large, resulting in an increase in the water temperature of the water curtain pool, thus affecting the cooling effect and increasing the operation cost. Content of the Utility Model

[0021] Furthermore, the above-mentioned water return port is located at the top of the micro water tank; the water outlet is located at the bottom of the micro water tank.

[0022] The beneficial effect of adopting the above further solution is that in the present utility model, by setting the water outlet at the bottom of the micro water tank, even when the water level in the micro water tank is too low, it can ensure that there is water flowing out of the water outlet, making the overall condensation water circulation smoother.

[0023] Furthermore, the above also includes a water replenishing device.

[0024] The beneficial effect of adopting the above further solution is that in the present utility model, since the water source stored in the micro water tank is limited, and during the water circulation process, a part of the water in the water curtain body will evaporate, so it is necessary to supplement the water source in the micro water tank through the water replenishing device.

[0025] Furthermore, the above-mentioned water replenishing device includes a control device, a liquid level gauge, an external water inlet, and a first electromagnetic valve. The liquid level gauge and the first electromagnetic valve are both connected to the control device. The liquid level gauge is arranged at the top of the micro water tank, and the first electromagnetic valve is arranged on the external water inlet.

[0026] The beneficial effect of adopting the above further solution is that in the present utility model, the water level height in the micro water tank is monitored by the liquid level gauge. When the water level in the micro water tank drops to a certain height, it means that the micro water tank needs to be replenished with water at this time. Then, the control device opens the first electromagnetic valve, so that the external water source enters the micro water tank through the external water inlet, achieving the effect of water replenishment.

[0027] Furthermore, the above also includes a lower drain port. The lower drain port is located at the bottom of the micro water tank, and a second electromagnetic valve is arranged on the lower drain port. The second electromagnetic valve is connected to the control device.

[0054] Embodiment 2:

[0055] This embodiment includes: a micro water tank 1, a circulation water pump 2, a spray pipe 6, and a water curtain body 7. The micro water tank 1 is located below the water curtain body 7. The micro water tank 1 includes a water outlet and a water return port. The water outlet is connected to the spray pipe 6 through a water inlet pipe 4. The circulation water pump 2 is arranged on the water inlet pipe 4. The spray pipe 6 is arranged at the top of the water curtain body 7. A return water pipe 8 is arranged at the bottom of the water curtain body 7. The return water pipe 8 returns the water leaching out from the bottom of the water curtain body 7 to the micro water tank 1 through connection with the water return port.

[0056] Optionally, it further includes a water replenishing device.

[0057] In the present utility model, since the water source stored in the micro water tank 1 is limited and a part of the water will be evaporated by the water curtain body 7 during the water circulation process, it is necessary to supplement the water source in the micro water tank 1 through a water replenishing device.

[0058] Optionally, the water replenishing device includes a control device, a liquid level gauge 10, an external water inlet 11, and a first solenoid valve 12. The liquid level gauge 10 and the first solenoid valve 12 are both connected to the control device. The liquid level gauge 10 is arranged at the top of the micro water tank 1, and the first solenoid valve 12 is arranged on the external water inlet 11.

[0059] In the present utility model, the water level in the micro water tank 1 is monitored by the liquid level gauge 10. When the water level in the micro water tank 1 drops to a certain height, it indicates that the micro water tank 1 needs to be replenished with water at this time.

The digital sensing liquid level gauge transmits the obtained water level information to the control device in the form of digital signals. The control device records and determines the received water level information. When the determination result is that water replenishment is required, an opening instruction is sent to the first solenoid valve 12. The first solenoid valve 12 responds to the opening instruction and opens the internal valve, so that the external condensed water enters the micro water tank 1 through the external water inlet 11 to realize the automatic control of the water level inside the micro water tank 1.

[0061] Specifically, the first solenoid valve 12 can be set with a fixed opening time. After the first solenoid valve is opened each time, when the preset fixed opening time is reached, the first solenoid valve 12 is closed to avoid damage to the micro water tank 1 caused by excessive injected water flow.

[0062] Specifically, the control device can determine the water level information by setting a water level threshold. When the water level information is higher than the water level threshold, there is no need to add water to the inside of the micro water tank 1. When the water level information is lower than the water level threshold, it indicates that a part of the condensed water has been evaporated by the water curtain body 7. To avoid the situation that the circulating water is not enough, water needs to be added to the micro water tank. Then, an opening instruction is sent to the first solenoid valve 12 at this time. The first solenoid valve 12 responds to the opening instruction and opens the internal valve, so that the external condensed water enters the micro water tank 1 through the external water inlet 11 to realize the automatic control of the water level inside the micro water tank 1.
