Description

Technical Field

[0001] The invention relates to the technical field of drainage equipment, and in particular to a negative pressure siphon drainage power station. Background Art

[0002] In the application field of negative pressure siphon drainage technology, traditional negative pressure siphon stations generally adopt a drainage mode that combines a vacuum pump and a water pump. Specifically, the vacuum pump is responsible for generating negative pressure in the tank, thereby sucking water into the storage tank. Subsequently, the water pump is started to pump out the accumulated water in the tank for discharge. Although this combined power equipment has met the drainage needs to a certain extent, its inherent limitations are also becoming increasingly prominent.

[0003] The primary problem is that the independent configuration of the vacuum pump and the water pump in the traditional process increases the complexity and overall cost of the system. In terms of maintenance, dual-power equipment means higher maintenance frequency and cost, and also brings additional management burden to the operators. In addition, in terms of space utilization, traditional negative pressure siphon stations often require a larger area to accommodate independent vacuum pumps and water pump devices, which is particularly disadvantageous in an environment where land resources are increasingly scarce.

[0004] More importantly, traditional negative pressure siphon stations have certain efficiency bottlenecks in their process design. Although the introduction of water pumps solves the drainage problem, it also increases energy consumption and reduces the overall energy efficiency of the system. In addition, the operation of water pumps often requires additional power support, which may limit the application scope of negative pressure siphon stations in some remote areas or areas with unstable power supply.

[0005] Based on this, the applicant proposed a negative pressure siphon drainage power station to solve the above technical problems. Summary of the invention

When the negative pressure tank B collects water, the exhaust channel is opened and the air inlet channel and the drainage channel are closed at the same time, negative pressure is generated in the negative pressure tank B and water is sucked in from the negative pressure tank A. When the negative pressure tank B drains water, the air inlet channel and the drainage channel are opened and the exhaust channel is closed at the same time, positive pressure is generated in the negative pressure tank B and water is discharged from the drainage channel.

[0016] Preferably, the negative pressure tank B is arranged on the upper side of the negative pressure tank A, and the vacuum pump is arranged on the upper side of the negative pressure tank B.

Embodiment 2:

[0028] A negative pressure siphon drainage power station of the present invention comprises a negative pressure tank A1 and a negative pressure tank B2, wherein the negative pressure tank A1 is provided with a water inlet channel, and the negative pressure tank B2 is provided with an air inlet channel, an exhaust channel and a drainage channel, and a connecting channel is provided between the negative pressure tank A1 and the negative pressure tank B2, when the negative pressure tank B2 collects water, the exhaust channel is opened and the air inlet channel and the drainage channel are closed at the same time, negative pressure is generated in the negative pressure tank B2 and water is sucked in from the negative pressure tank A1, and when the negative pressure tank B2 drains water, the air inlet channel and the drainage channel are opened and the exhaust channel is closed at the same time, positive pressure is generated in the negative pressure tank B2 and water is discharged from the drainage channel.

[0029] The water inlet channel includes a water inlet pipe 3 arranged on the upper side of the negative pressure tank A1, and a switch valve is arranged on the water inlet pipe 3. The drainage channel includes a drainage pipe 5 arranged on the drainage port 18 at the bottom of the side wall of the negative pressure tank B2, and an electric valve F8 is arranged on the drainage pipe 5. The connecting channel includes a connecting pipe 10, one end of which is arranged on the upper side of the negative pressure tank B2 and connected with the interior of the negative pressure tank B2, and the other end passes through the upper side wall of the negative pressure tank A1 and extends into the bottom of the negative pressure tank A1. The connecting pipe 10 is provided with an electric valve E9.

[0030] The air inlet passage includes a vacuum pump 4, the air inlet of the vacuum pump 4 is connected to the atmosphere through a pipeline, an electric valve B14 is provided on the pipeline, and the air outlet of the vacuum pump 4 is connected to the pressurization port 16 of the negative pressure tank B2 through a pipeline, an electric valve D13 is provided on the pipeline.

[0031] The exhaust channel includes a vacuum pump 4, the air inlet of the vacuum pump 4 is connected to the air suction port 17 of the negative pressure tank B2 through a pipeline, an electric valve A12 is provided on the pipeline, and the air outlet of the vacuum pump 4 is connected to the atmosphere through an exhaust pipe 11, and an electric valve C15 is provided on the pipeline.

[0032] The vacuum pumps of the above-mentioned intake channel and exhaust channel are independently set, that is, one part of the vacuum pumps is only used for the intake channel, and the other part of the vacuum pumps is only used for the exhaust channel. Under such a setting, the intake channel and the exhaust channel do not interfere with each other. By controlling them separately, the switching of intake and exhaust can also be achieved. Moreover, since they are set separately and do not interfere with each other, if damage occurs later, it can be quickly located and repaired.

[0033] The negative pressure tank B2 is also provided with a liquid level meter 6, which detects the water level in the negative pressure tank B2 to control the negative pressure tank B2 to collect water or drain water. The negative pressure tank B2 is also provided with a negative pressure gauge 7.

[0034] The negative pressure tank B2 is arranged on the upper side of the negative pressure tank A1, and the vacuum pump 4 is arranged on the upper side of the negative pressure tank B2. The negative pressure tank is used as the main structure of the equipment, and the vacuum pump and its piping system are cleverly arranged directly on the upper part of the negative pressure tank. The present invention maximizes the utilization of space and effectively reduces the overall footprint of the equipment. This design not only improves the utilization efficiency of land resources, but also provides more convenient conditions for the installation, commissioning and maintenance of the equipment.

[0035] There are two states when the present invention is running: Water collecting state: When the liquid level in the negative pressure tank B reaches the set low liquid level, it enters the negative pressure water collecting state. At this time, the electric valve A, electric valve C, and electric valve E are all in the open state, and the electric valve B, electric valve D, and electric valve F are all closed. At this time, the vacuum pump first discharges the gas in the negative pressure tank B to form a negative pressure inside the negative pressure tank B. At this time, the negative pressure tank B and the negative pressure tank A are in a connected state, and the negative pressure in the negative pressure tank A gradually increases (the pressure decreases), and the water is collected into the negative pressure tank A through the water inlet pipe. Since the vacuum pump first sucks the gas in the negative pressure tank B and then discharges the water or gas in the negative pressure tank A, the negative pressure in the negative pressure tank B is higher than the negative pressure in the negative pressure tank A. The pressure should be high or equal (low or equal), so the water and gas in the negative pressure tank A are sucked into the negative pressure tank B in turn. When the water in the negative pressure tank A is sucked to the lowest point, the gas in the negative pressure tank A starts to be discharged, and the negative pressures of the negative pressure tanks A and B gradually reach the same level. When the water in the negative pressure tank A continues to flood the lower part of the connecting pipe, the negative pressure in the negative pressure tank B is higher than the negative pressure in the negative pressure tank A (the pressure in the negative pressure tank A is lower than the pressure in the negative pressure tank B), and the water in the lower negative pressure tank A is sucked into the negative pressure tank B. The water sucked into the negative pressure tank B will be stored in the negative pressure tank B. When the liquid level in the negative pressure tank B gradually rises and reaches the set high liquid level, it stops; Drainage state: When the liquid level in the negative pressure tank B reaches the set high liquid level, it enters the drainage state, electric valve B, electric valve D, and electric valve F are all in the open state, and electric valve A, electric valve C, and electric valve E are all in the closed state. At this time, the negative pressure tank A is not connected to the negative pressure tank B, and the negative pressure in the negative pressure tank A will not be affected by drainage. Its pressure value is only affected by water inflow. When water inflow continues, the negative pressure in the negative pressure tank A gradually decreases (the pressure increases) until the internal and external pressures are balanced, and water will no longer flow into the negative pressure tank A. When draining, the vacuum pump works as a compression fan, sucking air from the outside and discharging the sucked gas into the negative pressure tank B. The negative pressure in the negative pressure tank B is converted into positive pressure, so that the water in the negative pressure tank B is discharged through the drain pipe until the liquid level stops after reaching the set low liquid level from the high liquid level.
