Description

Technical Field

[0001] The utility model belongs to the technical field of compressed air, in particular to a compressed air periodic drainage device. Background Art

[0002] A compressed air buffer tank is a pressure vessel specially used to store compressed air. It is used in conjunction with air compressors, refrigerated dryers, filters and other equipment to ensure smooth output of compressed air. On the one hand, it can separate liquid moisture from the compressed air. On the other hand, it can limit the frequent loading and unloading of the air compressor, protect the air compressor, and extend the service life of the air compressor. The existing compressed air buffer tank drainage is generally done by manually opening the drain valve and then using the drain valve for drainage;

[0003] However, due to the large number of compressed air buffer tanks in the compressed air buffer tank group, it is very time-consuming and labor-intensive to drain water using this treatment method, which greatly increases the labor cost. In addition, manual drainage may result in forgetting to drain the water, which may cause damage to the compressed air buffer tank.

[0004] Some timed drainage devices do not work well because the water content in the tank varies and the amount of water accumulated during the cycle is also different. Utility Model Content

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0026] See attached Figure 1-3A compressed air periodic drainage device of this embodiment includes a gas tank 100 and a drainage component 200. The drainage component 200 is provided at the bottom of the gas tank 100. The drainage component 200 includes a drainage pipe 210, a solenoid valve 220 and a regulating component 230. The regulating component 230 includes a position sensor 231, a glass tube 232, a connecting piece 233 and a float 234. The glass tube 232 is installed on the outside of the gas tank 100. Both ends of the glass tube 232 are connected to the inside of the gas pipe through the connecting piece 233. The float 234 is installed in the glass tube 232. A position sensor 231 is provided on one side of the glass tube 232. The position sensor 231 and the solenoid valve 220 are connected to an external controller together.

[0027] The float device 234 of this embodiment includes a bottom float 235 and a hollow iron ball 236 . The hollow iron ball 236 is installed on the bottom float 235 . The position sensor 231 is used to detect the position of the hollow iron ball 236 .

[0028] The position sensors 231 of this embodiment are installed at the bottom and the middle of the glass tube 232 , and the electrical signals corresponding to the position sensor 231 installed in the middle and the position sensor 231 installed at the bottom are start and stop.

[0029] In this embodiment, a mounting member 237 is provided on the glass tube 232, and the position sensor 231 is mounted on the mounting member 237. The mounting member 237 includes a ring member and a box member. The ring member is sleeved on the glass tube 232, and the position sensor 231 is mounted in the box member.

[0030] An emergency assembly 110 is provided at the bottom of the gas cylinder 100 of this embodiment. The emergency assembly 110 includes an emergency box 111 . A drain pipe 210 is inserted into the water in the emergency box 111 . A sound sensor 112 is provided on the inner top of the emergency box 111 .

[0031] Working principle: When a lot of water accumulates in the gas tank 100, the bottom float 235 rises along the glass tube 232 until the hollow iron ball 236 is detected by the middle position sensor 231. At this time, the controller controls the solenoid valve 220 to open for drainage. As the drainage continues, the bottom float 235 drops until the hollow iron ball 236 is detected by the bottom position sensor 231. Then the controller controls the solenoid valve 220 to close and stop drainage. The whole process does not require manual intervention, and regular drainage can be achieved. In order to avoid excessive drainage and exhaust caused by abnormalities in the control component 230, an emergency component 110 is provided. When exhaust begins, the gas comes out of the drain pipe 210 and enters the emergency box 111. Since there is water in the emergency box 111, bubbles will be generated and float to the surface to explode. The unique bubble explosion sound is detected by the sound sensor 112, which can transmit an electrical signal to the controller to control the solenoid valve 220 to close. It should be noted that detecting bubble sound belongs to the prior art and will not be repeated here. It is relatively simple to implement such detection.

[0032] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
