Description

Technical Field

[0001] This utility model relates to the field of mine drainage technology, and in particular to a water vapor separation detection device and drainage system. Background Technology

[0002] The determination of pump start-up conditions for mining water pumps refers to the determination of whether the pump meets the start-up conditions under process conditions such as vacuum priming and jet pump priming.

[0003] Currently, there are generally two types of conditions for starting water pumps in underground mines: one is to use a negative pressure sensor to monitor the negative pressure value in the pump's suction pipe. If the monitored negative pressure value reaches a set value, the pump is considered to have met the start-up conditions and can be started. However, because the suction pipe is not static, when a vacuum pump or jet pump extracts air from the suction pipe, the flowing gas inside causes fluctuations in the negative pressure sensor's readings. Simultaneously, the water pressure in the suction pipe after the pump starts can also cause some damage and pressure to the negative pressure sensor, resulting in large fluctuations in the sensor data, affecting the stability of the drainage system, and causing misjudgments.

[0004] The second method is to use a fixed-time water replenishment mode, which involves injecting water into the pump and its suction pipe for a certain period of time. Once the water replenishment time reaches the set value, the pump is started directly. However, due to the instability of the water volume and the inability to monitor the water replenishment status, it is impossible to directly detect whether the liquid in the pump and suction pipe meets the pump start-up requirements. Often, the pump fails to start due to insufficient water volume. Utility Model Content

[0005] The purpose of this invention is to provide a water vapor separation detection device and drainage system, which improves detection accuracy by ensuring that the liquid level monitoring is not affected by the dynamics inside the suction pipe.

[0006] The technical solution of this utility model is: a water vapor separation detection device, including a tank body, an exhaust pipe and a water inlet pipe connected to the tank body, the water inlet pipe being located at the lower end of the tank body, an installation pipe being provided at the upper end of the tank body, a liquid level sensor being provided at the top of the installation pipe for detecting changes in the liquid level inside the tank body to determine whether the pump start-up conditions have been met, one end of the liquid level sensor extending into the tank body from the installation pipe; a mechanical negative pressure gauge being provided on the exhaust pipe for monitoring the negative pressure inside the tank body.

[0007] Preferably, the exhaust pipe is further provided with an exhaust ball valve for controlling the opening and closing of the exhaust pipe.

[0008] Preferably, the tank body is provided with a filter plate, which is located near the water inlet pipe.

[0009] Preferably, the water inlet pipe is equipped with a manual valve for controlling the opening and closing of the water inlet pipe.

[0010] Preferably, the tank body is fixed by a mounting bracket, which is a channel steel.

[0011] This utility model also provides a drainage system, including a water pump, a motor for driving the water pump, a jet pump, a jet pipe, and the aforementioned water vapor separation detection device. The water pump is provided with a suction pipe and a drain pipe assembly. The exhaust pipe is connected to the jet pump. The jet pipe connects the jet pump and the drain pipe assembly. The inlet pipe is connected to the suction pipe.

[0012] Preferably, the jet pipe is provided with a high-pressure ball valve for controlling the on / off state of the jet pipe.

[0013] Preferably, the drain pipe assembly includes a tee pipe, wherein the first pipe of the tee pipe is connected to a water pump, the end of the second pipe of the tee pipe is connected to a first drain pipe, and the end of the third pipe of the tee pipe is connected to a second drain pipe.

[0014] Preferably, the pipe connecting the three-way pipe to the water pump is equipped with a check valve to prevent liquid in the three-way pipe from flowing back to the water pump and a drain valve to control the opening and closing of the three-way pipe.

[0015] Preferably, the pipe connecting the three-way pipe to the first drain pipe is equipped with a first water distribution valve, and the pipe connecting the three-way pipe to the second drain pipe is equipped with a second water distribution valve.

[0016] Compared with related technologies, the beneficial effects of this utility model are as follows: I. This utility model sets up a liquid level sensor on the water vapor separation detection device that can directly detect the liquid level in the tank, which is no longer affected by the non-static fluctuations in the suction pipe, avoids misjudgment, and improves detection accuracy; Second, this utility model adopts tank body liquid level detection, which makes detection more convenient, stable, and accurate. Third, the liquid level sensor installed on the tank body of this utility model can determine the water level of the suction pipe connected to the water inlet pipe of the tank body.

This method of detection is more accurate and clear. Fourth, the tank body of this utility model is equipped with a filter plate, which can effectively filter impurities in the water and protect the components inside the tank body.

[0022] The tank body 105 provides an environment for water vapor separation. Gas inside the tank body 105 is drawn away through the exhaust pipe 104. The inlet pipe 107 draws liquid from the suction pipe 14 of the water pump 12. A manual valve 106 is provided on the inlet pipe 107 to control its on / off state. A filter plate 108 is provided inside the tank body 105, positioned near the inlet pipe 107. The tank body 105 is fixed by a mounting bracket 109, which is made of channel steel. The mounting bracket 109 is an integral structure with the tank body 105, and has multiple mounting holes (unnumbered). The mounting bracket 109 is then connected to other fixing structures to secure the tank body 105.

[0023] like Figure 2As shown, this utility model also provides a drainage system, including a water pump 12, a motor 13 for driving the water pump 12, a jet pump 2, a jet pipe 3, and the aforementioned water vapor separation detection device 1. The water pump 12 is equipped with a suction pipe 14 and a drain pipe assembly 15. The exhaust pipe 104 is connected to the jet pump 2, and the jet pipe 3 connects the jet pump 2 and the first drain pipe 5 of the drain pipe assembly 15. The inlet pipe 107 is connected to the suction pipe 14. The jet pipe 3 is equipped with a high-pressure ball valve 4 for controlling the on / off state of the jet pipe 3. The jet pump 2 draws gas from the suction pipe 14 of the water pump 12 through a high-pressure water flow to create a negative pressure. A high-pressure jet water source flows inside the jet pipe 3.

[0028] When preparing to drain, open the high-pressure ball valve 4 and the exhaust ball valve 103, and start the jet pump 2 to extract the gas inside the water vapor separation detection device 1 and the suction pipe 14, causing the water vapor separation detection device 1 to discharge along the negative pressure pipeline to the outside, creating a negative pressure environment in the tank body 105. Open the hand valve 106, and the negative pressure draws the liquid from the suction pipe 14 into the tank body 105 through the inlet pipe 107. During the water filling process, the liquid level is detected in real time by the liquid level sensor 100.
