Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automatic liquid adding devices, and in particular to an automatic high-pressure liquid adding device. Background Art
[0002] Chemical oxygen demand, also known as chemical oxygen consumption, is the use of chemical oxidants (such as potassium permanganate) to oxidize and decompose oxidizable substances in water, and then calculate the oxygen consumption based on the amount of residual oxidants. The unit is generally ppm or mg / L. The smaller the value, the lighter the degree of water pollution. It is an important and quickly measurable organic pollution parameter in the study of river pollution and industrial wastewater properties and the operation and management of wastewater treatment plants.
[0003] The current method of adding liquid is to use a pipette to hit the inlet above the condenser or to use a measuring cylinder to measure an appropriate amount of solution and pour it into the inlet above the condenser. The solution transfer process is more dependent on manpower, and the solution may splash onto the experimenter's skin, causing safety concerns. Utility Model Content

[0006] Through the above scheme, through the setting of solenoid valves and high-pressure infusion pumps, the automatic extraction, merging and high-pressure delivery of solutions in multiple solution tanks are realized, without manual operation, which improves work efficiency. The solution tank is sealed with a sealing plug, which effectively prevents the leakage of solution and the entry of external impurities, ensuring the purity and safety of the solution. The liquid outlet head is provided to improve the safety and service life of the device. The device can adapt to the liquid addition needs of different solutions. By controlling the switch of the solenoid valve, the combination and delivery of different solutions can be realized, which has high flexibility.

[0008] Through the above scheme, the device can work without an external power supply through the built-in battery, thereby enhancing the independence and portability of its use.
[0009] Furthermore, a power switch is fixedly connected to one side of the housing.
[0010] Through the above solution, the power switch is directly fixed to one side of the casing, and the user can directly touch and operate it.

[0014] Through the above solution, by rotating the connected box door, the user can easily open or close the shell, thereby allowing the liquid adding tank to be placed in or taken out. The tank stopper on the box door plays the role of fixing the liquid adding tank, ensuring the stability of the liquid adding tank during the liquid adding process, and preventing it from shaking or moving, resulting in inaccurate liquid adding or leakage.
[0015] Furthermore, the three solution tanks are all fixedly arranged inside the fixing frame.
[0016] Through the above solution, the fixing frame not only provides stable support, but also makes the solution tanks arranged in an orderly and neat manner, which facilitates the user's daily management and maintenance of the solution tanks, such as checking the liquid level and replacing the solution.

The three sealing plugs 4 are fixedly connected with connecting pipes 6 inside. The outer walls of the three connecting pipes 6 are fixedly connected with solenoid valves 5. A fixing plate 7 is fixedly connected to one side of the shell 1. A confluence pipe 8 is fixedly connected inside the fixing plate 7. One end of the three connecting pipes 6 passes through the shell 1 and is fixedly connected to the confluence pipe 8. The confluence pipe 8 is fixedly connected to the end away from the connecting pipe 6. There is a hose 9, and several high-pressure infusion pumps 10 are fixedly connected to the outer wall of the hose 9. Through the arrangement of the solenoid valve 5 and the high-pressure infusion pump 10, the automatic extraction, merging and high-pressure delivery of solutions in multiple solution tanks 3 are realized without manual operation, which improves work efficiency. The end of the hose 9 away from the confluence pipe 8 is fixedly connected to a liquid outlet pipe 11, and the side of the liquid outlet pipe 11 away from the hose 9 is fixedly connected to a liquid outlet head 12, and the end of the liquid outlet pipe 11 away from the hose 9 is fixedly connected to a protective cover 13, which can effectively prevent it from being damaged or contaminated by the outside world.
[0032] See also Figure 1 , Figure 2 and Figure 5 A battery box 14 is fixedly connected to one side of the shell 1, and a battery 15 is fixedly connected inside the battery box 14. Through the built-in battery 15, the device can work without an external power supply, thereby enhancing its independence and portability in use. A power switch 16 is fixedly connected to one side of the shell 1. The power switch 16 is directly fixedly connected to one side of the shell 1, and the user can directly contact and operate it. The obvious position of the power switch 16 enables the user to easily turn on or off the device, effectively avoiding safety problems caused by misoperation and improving safety during use. A display screen 17 is fixedly connected to the upper surface of the shell 1, and the user can monitor the progress of the liquid adding process through the display screen 17.

By rotating the connected box door 18, the user can easily open or close the shell 1, thereby allowing the liquid adding tank to be placed in or taken out. The tank-blocks 19 on the box door 18 play a role in fixing the liquid adding tank, ensuring the stability of the liquid adding tank during the liquid adding process, and preventing it from shaking or moving to cause inaccurate liquid adding or leakage. The three solution tanks 3 are all fixedly arranged inside the fixing frame 2, which not only provides stable support, but also makes the solution tanks 3 arranged in an orderly and neat manner.

The liquid outlet head 12 is provided with a protective cover 13, which can effectively prevent it from being damaged or contaminated by the outside world, thereby improving the safety and service life of the device. The device can adapt to the liquid adding needs of different solutions.
