Description

Technical Field

[0001] The utility model relates to the technical field of vacuum water diversion, in particular to a vacuum water diversion system with strong suction. Background Art

[0002] At present, vacuum negative pressure stations have been widely used in large pumping stations, water plants, sewage pumping stations and flood drainage pumping stations. The vacuum negative pressure station is a complete system with two water ring vacuum pumps as vacuum acquisition equipment and a vacuum tank as a vacuum storage equipment. For occasions where the vacuum source is frequently used and the required air extraction volume is not too large, this system greatly saves energy compared to directly using a vacuum pump and effectively increases the service life of the vacuum pump.

[0003] When the vacuum tank is in use, a certain gap needs to be retained at the top. When the water pump is started, it will first draw water from the vacuum tank. As the water is drawn out, the liquid level in the vacuum tank begins to drop, and the gap pressure at the top decreases: as the water level drops, the pressure in the tank is lower than the atmospheric pressure of the pool liquid surface, and the water in the pool will enter the vacuum tank along the suction pipe, filling the low-pressure area in the tank and realizing the water supply operation. However, the gap volume at the top of the tank cannot be adjusted, which results in the need to use an exhaust pipe to replenish or exhaust air when the internal volume needs to be adjusted. Long-term use may lead to a decrease in air tightness and reduced equipment performance. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a vacuum water diversion system with strong suction to solve the technical problem that when the internal volume needs to be adjusted, an exhaust pipe needs to be used to replenish or exhaust air, which may cause a decrease in air tightness after long-term use, resulting in reduced equipment performance.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum water diversion system with strong suction, comprising a base, a vacuum tank is fixedly connected to one side of the top of the base, a through hole is opened on the top of the vacuum tank, a floating plate is fixedly connected to the bottom of the through hole through a sealing film, an air bag for adjusting the volume is arranged above the floating plate, and the air bag is connected to an external air pump.

[0006] By adopting the above technical solution, the volume inside the vacuum tank can be easily adjusted by connecting the air bag with the external air pump, thereby achieving pressure control and improving the pumping flexibility and work efficiency of the equipment.

[0007] Furthermore, a liquid level rod is fixedly connected to the top of the floating plate, and a scale for indicating the liquid level is provided on the liquid level rod.

[0008] By adopting the above technical solution, by fixing the liquid level rod on the top of the floating plate, the liquid level height in the vacuum tank can be intuitively displayed, making it easy to observe the water level inside the equipment, thereby ensuring the safety of the equipment.

[0009] Furthermore, an exhaust pipe and a water injection port are provided on the other side of the top of the vacuum tank.

[0010] By adopting the above technical solution, by setting an exhaust pipe on the other side of the top of the vacuum tank, the gas in the tank can be easily discharged to adjust the pressure in the tank or perform necessary exhaust operations to prevent excessive internal pressure.

[0011] Furthermore, a water inlet pipe is provided on one side of the vacuum tank, and a water outlet pipe is provided on the other side of the vacuum tank.

[0012] By adopting the above technical solution, by setting a water inlet pipe on one side of the vacuum tank, it is possible to easily connect to an external water source to automatically fill water into the tank, thereby ensuring continuous water supply to the water diversion system and ensuring that subsequent equipment can operate stably.

[0013] Furthermore, a pump is fixedly connected to one side of the water outlet pipe, and the pump is fixedly connected to the base.

[0014] By adopting the above technical solution, by fixing a pump on one side of the water outlet pipe, the power of the pump can be used to pump water out of the vacuum tank, thereby improving the efficiency and stability of water outlet.

[0015] Furthermore, a fixing block is fixedly connected to the top of the through hole, and a sliding hole is provided inside the fixing block.

[0016] By adopting the above technical solution, a fixed block fixedly connected through the top of the through hole provides a stable supporting structure for the liquid level rod, ensuring that the equipment can work stably.

[0017] Furthermore, the sliding hole and the liquid level rod are slidably connected.

[0018] By adopting the above technical solution, the sliding connection between the sliding hole and the liquid level rod ensures that the liquid level rod can slide up and down freely and stably in the fixed block.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. The utility model realizes flexible adjustment of the internal volume of the vacuum tank by setting a sealing film, a floating plate and an air bag, so that the pressure can be temporarily controlled, and the sealing of the equipment is ensured by the sealing film to prevent gas leakage. By using the floating characteristics of the floating plate and the liquid level rod, the operator can visually observe the liquid level inside the vacuum tank, effectively preventing the equipment from not working properly due to lack of water or air leakage, which may cause damage to the pump;

[0021] 2. The utility model provides a liquid level rod and a fixed block, so that the operator can directly observe the liquid level in the vacuum tank. At the same time, the design of the fixed block enables the liquid level rod to slide vertically up and down stably, effectively preventing the liquid level rod from shaking, thereby ensuring the accuracy of liquid level observation.

[0033] See also Figure 1 and Figure 2 A liquid level rod 7 is fixedly connected to the top of the floating plate 5, and a scale for indicating the liquid level is set on the liquid level rod 7. By fixing the liquid level rod 7 on the top of the floating plate 5, the liquid level height in the vacuum tank 2 can be intuitively displayed, so that the water level inside the equipment can be easily observed, thereby ensuring the safety of the equipment. At the same time, the scale set on the liquid level rod 7 can accurately indicate the specific position of the liquid level, which helps the operator to timely understand and monitor the water amount in the tank body, thereby effectively preventing the problem of equipment damage caused by lack of water.

[0034] See also Figure 1 and Figure 2 An exhaust pipe 8 and a water injection port 9 are provided on the other side of the top of the vacuum tank 2. By providing the exhaust pipe 8 on the other side of the top of the vacuum tank 2, the gas in the tank body can be conveniently discharged to adjust the pressure in the tank or perform necessary exhaust operations to prevent the internal pressure from being too high. At the same time, the provision of the water injection port 9 makes it simple and quick to inject water into the vacuum tank 2, which can facilitate water replenishment when water is scarce, thereby improving the usability and maintenance efficiency of the equipment.

[0035] See also Figure 1 and Figure 2 A water inlet pipe 10 is provided on one side of the vacuum tank 2, and a water outlet pipe 11 is provided on the other side of the vacuum tank 2. By providing the water inlet pipe 10 on one side of the vacuum tank 2, it is convenient to connect to an external water source to realize automatic water injection into the tank, thereby ensuring continuous water supply to the water diversion system and ensuring that subsequent equipment can operate stably.
