Detailed Description
The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.
As a preferred embodiment of the invention, as shown in figure 1, the nondestructive drainage device of the air compressor mainly comprises a liquid storage tank 2, a float switch 3 and an electromagnetic drainage valve 4, wherein the electromagnetic drainage valve is linked with the float switch through a relay. The concrete structure of each part is as shown in the figure,
the liquid storage tank 2 is provided with a water outlet 22, a first liquid level height A, a second liquid level height B and a water inlet 21 which are distributed from bottom to top, the water inlet 21 is connected with a bottom pipeline 11 of the air storage tank 1 of the air compressor, namely the water inlet 21 is lower than the bottom of the air storage tank 1, so that water can smoothly flow into the liquid storage tank 2. Different from the structural design of the traditional drainage scheme, the liquid storage tank is introduced to serve as a buffer container for drainage of the air storage tank, and is mainly used for collecting and continuously accumulating moisture separated in the production process of compressed air. The liquid storage tank is an open container integrally formed by welding DN100 seamless steel tubes, and the upper end of the liquid storage tank is connected with a top cover 24 through a flange and a detachable bolt (not shown), and is mainly used for temporary opening during fault check. And the top cover 24 is also provided with a hole with the diameter of 10mm, and is used for matching with the assembly and the action of the float switch.
The float switch 3 is suspended in the liquid storage tank 2 and ascends and descends along with the liquid level, the top of the float switch is a rigid pipe, and the rigid pipe is connected in a hole formed in the top cover of the liquid storage tank in a penetrating mode and is in guide sliding connection, so that the axial stability of the floating ascending and descending of the float switch can be guaranteed. And a signal wire connected with the relay 5 is arranged in the rigid pipe in a penetrating way and used for feeding back liquid level information and outputting a driving signal to the relay when the float switch rises or falls to a specific liquid level.
The electromagnetic drain valve 4 is connected between the water outlet 22 and the lossless drainage outlet 25 and is connected with the power input end through a relay. From the linkage control, the float switch rises to a second liquid level height B, the stored liquid is judged to be excessive, the relay is controlled to be connected and supplies power to the electromagnetic drain valve for draining, the float switch falls to a first liquid level height A along with the drained water, the liquid level is judged to be acceptable, the relay is controlled to be separated, and the electromagnetic drain valve is powered off, hung and stopped to drain the water.
In the preferred embodiment, in order to further improve the drainage operation, on the basis of the above-mentioned full-automatic drainage part, the present creation also reserves a drainage design as a compensation measure on the liquid storage tank, that is, the liquid storage tank 2 is provided with a third liquid level height C and a reserved port 23 above the water inlet, the reserved port 23 is externally connected with a mechanical drainage valve 6 with an emergency drainage port, and a water drawing pipe 61 of the mechanical drainage valve 6 extends to a position below the second liquid level height B. Usually, the compensation measure does not work, and only when a float switch or an electromagnetic drain valve for automatic drainage breaks down, the compensation measure participates in the drainage action.
In addition, as an alternative implementation, the water inlet 21, the water outlet 22 and the reserved port 23 may be set as a unified DN15 external thread joint. A sensor for detecting liquid level exceeding can be arranged between the second liquid level height B and the third liquid level height C to warn the fault of an external system.
Therefore, in the drainage process of the preferred embodiment, the water in the liquid storage tank is accumulated continuously, the liquid level rises, the float switch gradually rises to the second liquid level height B, the signal of the float switch is transmitted to the relay, and the function of the electromagnetic drainage valve is combined to perform braking drainage. And along with the liquid level constantly drops to first liquid level height A of carrying out the drainage, then the float switch passes through relay transmission turn-off signal, and the drainage stops. The whole drainage process has no redundant compressed air to be discharged, and the lossless drainage function is realized.
To sum up about the utility model discloses technical scheme's embodiment details can be seen, and its application effect is showing: the device utilizes the float switch to go up and down along with the liquid level and carries out automatic drainage in linkage electromagnetism drain valve in predetermined height liquid level department, but has not saved the settlement of drainage time and artifical timing participation drainage, has realized compressed air's zero release moreover. After three-month trial, the device automatically drains water once every 3-5 minutes, water with the liquid level height of 300mm is drained every time, and compressed air is not discharged, so that the expected effect is achieved.
In addition to the above embodiments, other embodiments of the present invention are also possible. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention as claimed.
