Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic drainage of gas storage tanks, in particular to a novel automatic drainage device for compressed air storage tanks. Background Art
[0002] The compressed air delivered by our factory's air compressor station passes through the compressed air storage tank and is then delivered to various gas consumption points in the factory. Due to the high water content of the compressed air, the water in the compressed air is separated in the storage tank and deposited at the bottom of the storage tank. Therefore, it is necessary to manually open the drain valve at the bottom of the storage tank frequently to drain the water, which also causes energy to be wasted when the compressed air is discharged. In the past two years, due to the low winter temperature, the water at the bottom of the storage tank was not discharged in time and froze, blocking the gas outlet of the storage tank. The production site was shut down for about 4 hours due to the lack of compressed air, causing significant economic losses. To solve the above problems, a new automatic drainage device for compressed air storage tanks is proposed. Summary of the Invention
[0003] The purpose of the utility model is to solve the above problems and provide a novel automatic drainage device for compressed air storage tanks.
[0004] The specific scheme of the utility model is: a new type of automatic drainage device for compressed air storage tanks, comprising: an air tank, an air inlet pipe is provided on one side of the air tank, and an air outlet pipe is provided on the other side of the air tank; a water tank is provided below the air tank, a connecting pipe is provided at the bottom of the air tank, and the connecting pipe is connected to the bottom of the water tank; a vent pipe is provided on the upper part of the water tank, and the other end of the vent pipe is connected to the air outlet pipe, a float-type liquid level relay is provided in the water tank, a low-level trigger point is provided in the middle part of the water tank, and a high-level trigger point is provided above the low-level trigger point, the float-type liquid level relay is connected to the control box signal, a drain pipe is provided at the bottom of the water tank, a drainage device is provided on the drain pipe, and the float-type liquid level relay is connected to the drainage device signal for controlling the drainage device to automatically drain.
[0005] Furthermore, the drainage device is a drainage solenoid valve, and the drainage solenoid valve is connected to the control box signal.
[0006] Furthermore, a valve is provided on the connecting pipe.
[0007] Furthermore, a valve is provided on the ventilation pipe.
[0008] The control principle of the utility model is as follows: the water in the gas tank enters the water tank through the connecting pipe. When the float of the float-type liquid level relay rises to the low trigger point along with the water level, the reed switch contact closes and sends a signal to the control box. At this time, the light on the control box lights up; when the float continues to rise to the high trigger point, the other reed switch contact closes and sends a signal to the control box. At this time, the control box controls the drain solenoid valve to open for automatic drainage. When the float drops below the low trigger point, the electric control box controls the drain solenoid valve to close. This cycle realizes automatic drainage.
[0009] The utility model has the following beneficial effects: the utility model has a simple structure and is easy to use. When the water level in the water tank reaches the low-level trigger point, the float-type liquid level relay sends a signal to the control box, and the light of the control box lights up. When the water level in the water tank reaches the high-level trigger point, the float-type liquid level relay sends a signal to the control box, and then the control box controls the drain solenoid valve to realize automatic drainage; this cycle is repeated to realize automatic drainage, greatly improve work efficiency, and prevent water freezing in the gas tank from causing blockage.
