Problems solved by technology

The structure is simple, but the liquid reservoir of this scheme is connected to the atmosphere. Once the water pump cannot pump the excess liquid back into the liquid reservoir, a large amount of liquid in the liquid reservoir will flow into the container, causing overflow; and it contains a large amount of liquid The liquid reservoir must be placed at a height higher than the target liquid level, which is likely to cause safety hazards
Therefore present automatic maintenance liquid level technology all has certain defect

Embodiment 1

[0034] This embodiment provides a simple and convenient liquid level automatic maintenance device, its structure is as follows: figure 2 As shown, it includes a vent tube 1 and a sealed fluid replacement device 2 . The upper end of the vent pipe 1 is connected to the water outlet of the sealed fluid replacement device 2 , and the nozzle at the lower end of the vent pipe 1 is located at the target liquid level height 6 in the container 5 .

[0035] The sealed liquid replenishment device 2 is a closed water tank, and the water outlet is at the bottom of the device, and the water outlet remains below the liquid level during the maintenance of the liquid level. Place the sealed liquid replenishment device 2 at a high place so that the liquid level therein is higher than the target liquid level height 6, and the liquid in the sealed liquid replenishment device 2 that is higher than the target liquid level is subjected to downward gravity to make the air pressure in the sealed liqu...

Embodiment 2

[0038] This embodiment provides a liquid level automatic maintenance device that separates air intake and liquid addition. The device is as follows: image 3 As shown, it includes a vent pipe 1 , a sealed fluid replacement device 2 and a first water outlet pipe 4 . The ventilation pipe 1 is connected with the upper air inlet of the sealed liquid replenishment device 2 , and the water outlet of the sealed liquid replenishment device 2 is connected with the top (water inlet) of the first water outlet pipe 4 .

[0039] The nozzle at the lower end of the vent pipe 1 is located at the target liquid level 6 in the container 5 .

[0040] The sealed liquid replenishment device 2 is a closed water tank, and the water outlet is at the bottom of the device, and the water outlet remains below the liquid level during the maintenance of the liquid level. Place the sealed liquid replenishment device 2 at a high place so that the liquid level in it is higher than the target liquid level heig...

Embodiment 3

[0045] This embodiment provides a liquid level automatic maintenance device that is easy to place, and its structure is as follows: Figure 4 As shown, the device includes a ventilation pipe 1 , a sealed liquid replenishment device 2 , a water pump 3 , a second water outlet pipe 7 and a water replenishment pipe 8 .

[0046]The nozzle at one end of the ventilation tube 1 is located at the target liquid level 6 in the container 5 , and the other end communicates with the air inlet at the top of the sealed liquid replacement device 2 . The sealing liquid replenishing device 2 is a gas washing bottle used in reverse. One end of the second outlet pipe 7 enters from the water outlet of the sealing liquid replenishing device 2 and extends below the liquid level in the device, and the other end is connected to the water inlet of the water pump 3 . What water pump 3 adopted is micro gear pump, and the rotating speed of gear pump is adjustable. The water outlet of the replenishment pip...

Abstract

The present invention provides a liquid level automatic maintenance device and method. The device comprises a container configured to hold liquid; a sealing fluid infusion device configured to hold supplement liquid; a breather pipe, wherein the port of one end of the breather pipe is located at the target liquid level of the container, and the other end of the breather pipe is communicated with the top end of the sealing fluid infusion device; a water pump; a discharging tube which has one end stretching into the liquid surface in the sealing fluid infusion device and has the other end connecting with the water inlet of the water pump; and a water supplement tube which has one end connecting the water outlet end of the water pump and has the other end connected with the container. When the liquid surface in the container is lower than the target liquid level, the water pump is configured to suck the air from one end of the breather pipe into the sealing fluid infusion device, the supplement liquid with the same amount in the sealing fluid infusion device is pumped through the discharging tube and is flowed into the container from the water supplement tube so as to realize that the liquid level in the container maintains at the target liquid level. The structure is simple, the usage is convenient, and the stability and the safety are high.

Description

technical field [0001] The invention relates to the control of liquid level height, in particular to an automatic liquid level maintenance device and method. Background technique [0002] In industrial production or experiments, it is often necessary to maintain the liquid level in the container at a certain height, but the evaporation, volatilization or consumption of the liquid may cause the liquid level to drop, and it is necessary to replenish the liquid in time to automatically maintain the liquid level. [0003] At present, there are more commonly used technologies for automatically maintaining the liquid level. Generally, a liquid level sensor is used to detect the liquid level, and then the control circuit controls the opening of the water pump or valve to replenish the liquid in the container. The structure is often complex, and the stability of electronic products cannot be guaranteed. Once a problem occurs in the detector or control part, it may not be able to eff...
