Technical Field
[0001] This application relates to the field of drainage device technology, specifically a quantitative drainage device for an automatic drainage system for vacuum tanks. Background Technology
[0002] Automatic drainage of vacuum tanks is designed to effectively manage and discharge liquids within the tank, preventing liquid buildup that could affect the vacuum status or normal operation of the equipment.
[0003] Existing drainage devices can perform automatic drainage, but they have shortcomings: 1. Conventional drainage devices drain water by controlling the operation of the drainage equipment, so it is necessary to set the start time of the equipment, which requires manual intervention and makes manual work cumbersome; 2. As a drainage function similar to timed drainage, the drainage function cannot control the balance after drainage, resulting in a certain amount of energy waste.
[0004] To address the aforementioned technical problems, a quantitative drainage device for an automatic drainage system of a vacuum tank is proposed as a solution. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a quantitative drainage device for an automatic drainage system for vacuum tanks. This device features advantages such as using sensor signals as pneumatic commands for the drainage device, automatic drainage without manual intervention to set the time, and energy-saving quantitative drainage.
[0006] To achieve the above objectives, this application provides the following technical solution: a quantitative drainage device for an automatic drainage system of a vacuum tank, comprising a vacuum tank and a drainage pipe for a water storage chamber connected to the bottom of the vacuum tank. A cavity partition is fixedly installed on the inner wall of the vacuum tank, and a water pipe for draining into the water storage chamber is fixedly installed on the outer wall of the vacuum tank. A float sensor is also mounted on the side of the vacuum tank, and a float structure is provided on the side of the cavity partition facing the water storage chamber.
[0007] The float structure includes a float seat fixedly installed on the cavity partition, a guide tube communicating with the float seat, and a float located inside the guide tube.
[0008] Furthermore, the upper cavity of the vacuum tank is a vacuum cavity, the lower part of the vacuum tank is a water storage cavity, and the cavity partition is tightly attached to the inner wall of the vacuum tank.
[0009] Furthermore, the upper end of the water pipe that drains into the water storage chamber is connected to the vacuum chamber of the vacuum tank, and the lower end of the water pipe that drains into the water storage chamber is connected to the water storage chamber of the vacuum tank.
[0010] Furthermore, the vacuum tank is also connected to a negative pressure synchronization pipe and a positive pressure gas source inlet pipe.
[0011] Furthermore, pneumatic ball valves are installed on the water pipe into the water storage chamber, the water storage chamber drain pipe, the negative pressure synchronization pipe, and the positive pressure air source access pipe to control the opening and closing of the pipeline.
[0012] Furthermore, the outer wall of the float seat is uniformly provided with exhaust holes that communicate with the guide tube.
[0013] Furthermore, a slide bar is fixedly installed on the inner wall of the guide tube, and a groove corresponding to the slide bar is opened on the outside of the float ball, and the slide bar and the groove slide relative to each other.
[0014] Furthermore, a through hole for liquid to enter is provided at the bottom end of the guide tube.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] The automatic drainage system for this vacuum tank uses a quantitative drainage device that divides the vacuum tank into two areas by a partition, connects them with a water pipe that drains into the storage chamber, and incorporates a float sensor. This allows for convenient control of the quantitative drainage of water from the storage chamber. Quantitative drainage is achieved by controlling the pressure and flow rate of the positive pressure gas source inlet pipe.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] Please see Figures 1 to 4 The quantitative drainage device of the automatic drainage system for vacuum tank in this embodiment includes a vacuum tank 1 and a water storage chamber drain pipe 5 connected to the bottom of the vacuum tank 1. The vacuum tank 1 has a vacuum chamber inside, and a chamber partition 3 is fixedly installed on the inner wall of the vacuum tank 1 to divide the inner cavity of the vacuum tank 1 into two independent spaces, upper and lower.
[0024] Furthermore, the upper cavity of the vacuum tank 1 is a vacuum cavity, the lower part of the vacuum tank 1 is a water storage cavity 2, and the cavity partition 3 is tightly attached to the inner wall of the vacuum tank 1.
[0025] Preferably, a water pipe 4 for draining into the water storage chamber is fixedly installed on the outer wall of the vacuum tank 1. The upper end of the water pipe 4 is connected to the vacuum chamber of the vacuum tank 1, and the lower end of the water pipe 4 is connected to the water storage chamber 2 of the vacuum tank 1. At this time, the upper and lower chambers of the vacuum tank 1 are connected and both are in a vacuum negative pressure state.
[0026] This design allows water vapor to accumulate inside the vacuum chamber of vacuum tank 1 and then flow into the water storage chamber 2 through the water pipe 4 for storage.
[0027] In this embodiment, the vacuum tank 1 is also connected to a negative pressure synchronization pipe 6 and a positive pressure gas source inlet pipe 7.
[0028] Preferably, pneumatic ball valves are installed on the above-mentioned water pipe 4 for draining into the water storage chamber, water pipe 5 for draining from the water storage chamber, negative pressure synchronization pipe 6, and positive pressure air source access pipe 7 to control the opening and closing of the pipelines.
[0029] It should be noted that a float sensor 8 is also mounted on the side of the vacuum tank 1, and a float structure is provided on the side of the cavity partition 3 facing the water storage cavity 2.
[0030] In this embodiment, the float structure includes a float seat 9 fixedly installed on the cavity partition 3, a guide tube 11 connected to the float seat 9, and a float 12 located in the guide tube 11.
[0031] Furthermore, the outer wall of the float seat 9 is evenly provided with exhaust holes 10 that are connected to the guide tube 11. By setting the exhaust holes 10, the gas in the guide tube 11 can be discharged out of the guide tube 11.
[0032] Preferably, a slide bar 14 is fixedly installed on the inner wall of the guide tube 11, and a groove 13 corresponding to the slide bar 14 is opened on the outside of the float 12. The slide bar 14 and the groove 13 slide relative to each other, which can restrict the rotation of the float 12 relative to the guide tube 11.
[0033] In this embodiment, a through hole 15 for liquid to enter is provided at the bottom end of the guide tube 11. By setting the through hole 15, the liquid level in the water storage chamber 2 can be level with the liquid level in the guide tube 11.
[0034] In this embodiment, the bottom end of the guide tube 11 is closed, and the diameter of the connecting hole 15 is smaller than the diameter of the float 12.
[0035] This design ensures that the float 12 cannot detach from the guide tube 11, and that signal-controlled drainage can be completed when the float 12 corresponds to the position of the float sensor 8.
[0036] The working principle of the above embodiments is as follows:
[0037] The vacuum chamber and the water storage chamber 2 are independently sealed and separated by a chamber partition 3. During operation, the water pipe 4 that drains into the water storage chamber is normally open, connecting the vacuum chamber and the water storage chamber 2. This keeps both chambers under negative pressure. After water vapor accumulates in the vacuum chamber, it flows into the water storage chamber 2 through the water pipe 4. When the water level in the water storage chamber 2 rises, water enters the guide pipe 11 through the connecting hole 15 at the bottom. At this time, the float 12 rises synchronously with the liquid level in the guide pipe 11. When the water level reaches the same value, the switch is triggered, realizing the actual drainage, i.e., the float sensor... 8. A signal is sent to start the drainage procedure. First, the pneumatic ball valves on the water inlet pipe 4 and the negative pressure synchronization pipe 6 are closed, completely isolating the upper and lower cavities in the vacuum tank 1. Then, the positive pressure air source inlet pipe 7 is opened, and positive pressure air is injected into the water storage cavity 2. The water storage cavity drain pipe 5 is opened, and the positive pressure discharges the water in the water storage cavity 2 through the water storage cavity drain pipe 5. After the predetermined drainage time is reached, the positive pressure air source inlet pipe 7 and the water storage cavity drain pipe 5 are closed, making the water storage cavity 2 sealed. Then, the water inlet pipe 4 and the negative pressure synchronization pipe 6 are opened, making the negative pressure of the upper and lower cavities of the cavity partition 3 synchronized, and the drainage action ends.
