Description

Technical Field

[0001] The utility model relates to the field of isolating agent storage tanks, in particular to an automatic cleaning device for a liquid level gauge. Background Art

[0002] As we all know, after the rubber is processed and cooled in the internal mixer, an isolation agent is needed to isolate the rubber. The liquid level display of the isolation agent storage tank uses a magnetic suspension level gauge. Due to the characteristics of the isolation agent, impurities such as powdery agglomerates will be produced during the alternating temperature changes. The float cannot guarantee the accuracy of the liquid level display under the support of the powder, which affects the proportion of the isolation agent and further affects the quality of rubber production. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an automatic cleaning device for a liquid level gauge, which can automatically and regularly clean the liquid level gauge of an isolation agent storage tank.

[0004] The utility model adopts the following technical scheme to solve the technical problems: an automatic cleaning device for a liquid level gauge is provided, the liquid storage tank is supported and fixed by a liquid storage tank base, and the characteristic is that a sewage discharge hand valve is provided below the liquid storage tank, the sewage discharge hand valve is connected to a recovery tank through a sewage discharge pipeline, an upper liquid level control valve and a lower liquid level control valve are provided on a channel connecting the liquid level gauge to the liquid storage tank, a liquid level gauge float is provided in the liquid level gauge, a water inlet pneumatic ball valve and a sewage discharge pneumatic ball valve are installed at the upper and lower ends of the liquid level gauge, the sewage discharge pneumatic ball valve is connected to the recovery tank through the sewage discharge pipeline, the cleaning water main pipeline is connected to the water inlet pneumatic ball valve through a connecting pipeline, the pneumatic control ends of the water inlet pneumatic ball valve, the upper liquid level control valve, the lower liquid level control valve and the sewage discharge pneumatic ball valve are respectively connected to one end of a first air pipeline, a second air pipeline, a third air pipeline and a fourth air pipeline, and the other ends of the first air pipeline, the second air pipeline, the third air pipeline and the fourth air pipeline are connected to a control valve group, and the control valve group is controlled by a timer.

[0005] The beneficial effect of the utility model is that the cleaning medium water is passed into the liquid level meter for flushing. After the cleaning is completed, the control valves are opened in sequence through the control of the valve group to restore the liquid level display function of the storage tank, thereby realizing the automatic cleaning and accurate liquid level display functions of the liquid level meter.

When the timer 15 sends a start signal, the control valve group 16 first closes the lower liquid level control valve 9 and the upper liquid level control valve 4 according to the instruction, and then opens the sewage pneumatic ball valve 8 and the water inlet pneumatic ball valve 3, so that the clean water in the cleaning water main pipeline 1 enters the liquid level gauge 6, and the gap between the liquid level gauge float 5 and the inner wall of the liquid level gauge 6 is used to flush the inside of the liquid level gauge 6. The soapy liquid residue after flushing is recovered to the recovery tank 13 through the sewage pipeline 14. The flushing time is set by the timer 15. After completing the flushing task, the timer 15 sends a closing signal, and the control valve group 16 restores each valve group to its initial switch position in turn according to the instruction, thereby completing the purpose of automatically cleaning and restoring the liquid level display.
