Technical Field
[0001] The utility model relates to the technical field of air compressors, in particular to an automatic drainage device for an oil tank of an air compressor. Background Art
[0002] When the air tank of the air compressor equipment on the market is used, the compressed air will heat up and then cool down, which will cause a lot of water in the screw oil. When the equipment stops working, the inside of the oil tank will cool down. During this process, cooling water will accumulate inside the oil tank. The equipment works in this environment for a long time. As the oil tank is used day by day, the water vapor inside the oil tank condenses and cannot be discharged in time, so water droplets will accumulate at the bottom of the oil tank. With long-term use, the water droplets will accumulate more and more, causing the screw oil in the oil tank to contain a lot of water. The water in the screw oil will cause the pipes and joints to rust, which will cause the machine head to get stuck, thus affecting the stability of the machine head.
[0003] At present, most users usually open an oil drain port at the bottom of the oil tank and rely on experience to properly drain the accumulated water in the oil tank. However, more often than not, users ignore this problem, which greatly reduces the service life of the screw machine's yin and yang rotors, oil pipes, joints and other components. Especially when working in the hot and humid environment of the south, the large amount of water accumulated in the oil tank during the heating and cooling process will cause more serious damage to the service life of the screw machine head.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides an automatic drainage device for an oil tank of an air compressor. Figure 1-Figure 3 As shown, the oil tank 1 includes a cathode terminal 2 and an anode terminal 3 on both sides of the bottom of the oil tank 1, one end of the cathode terminal 2 and the anode terminal 3 extends into the oil tank 1, and the other end is connected to the control circuit. A drain port 4 is provided at the bottom of the oil tank 1, and an electric drain valve 5 is installed on the drain port 4. In order to prevent the current of other electrical components from interfering with the electric drain valve 5, it is necessary to define the drain button as a shutdown state in the control circuit before it can be started. The electric drain valve 5 is connected to the control circuit, and the cathode terminal 2, the anode terminal 3 and the electric drain valve switch 8 are respectively connected to the power supply device 9. Through the precise sensing of the cathode terminal 2 and the anode terminal 3, the real-time monitoring of the water level inside the oil tank 1 is realized. When the water level reaches the predetermined threshold, the control circuit will respond quickly and control the opening of the electric drain valve 5, thereby automatically draining the accumulated water in the oil tank 1. This innovative design not only effectively avoids the long-term accumulation of water inside the oil tank, reduces the water content in the screw oil, but also significantly improves the working life and stability of key components such as the screw machine, oil hard pipe, and joints.
[0022] In this embodiment, the cathode terminal 2 and the anode terminal 3 are 3 to 5 mm higher than the bottom of the oil tank. Of course, we can change the positions of the cathode terminal 2 and the anode terminal 3 on the oil tank 1 according to different environmental conditions to meet the needs of different situations.
[0023] Specifically, the control circuit is provided with an alarm 7 and an adjustable resistor 6. The alarm 7 is an audible and visual alarm. The adjustable resistor 6 allows the operator to adjust the sensitivity and response speed of the control circuit according to actual needs.
[0024] Furthermore, the diameter of the drain port 4 is 4 mm. In order to ensure smooth drainage, the drain port should be neither too large nor too small, and a size of 4 mm is required to facilitate smooth drainage.
[0025] Furthermore, the electric drain valve 5 adopts a normally closed electromagnetic drain valve. When the coil is energized, the armature first drives the valve plug of the auxiliary valve to be lifted under the action of the electromagnetic force, and the fluid on the valve cup of the main valve flows away through the auxiliary valve, reducing the pressure acting on the valve cup of the main valve. When the pressure on the valve cup of the main valve is reduced to a certain value, the armature drives the valve cup of the main valve, and uses the pressure difference to open the valve cup of the main valve, so that the medium flows. After the coil is powered off, the electromagnetic force disappears, and the armature falls back to its original position due to its own weight. At the same time, relying on the medium pressure, the main and auxiliary valves can be tightly closed.
[0026] Furthermore, the power supply device 9 is a 24V, 200A battery shared by the system electrical system. As a reliable energy supply, the battery can ensure that the device can operate stably under various working conditions and will not affect its normal function due to insufficient power.
[0027] Furthermore, the liquid at the bottom of the oil tank 1 is stratified into an upper diesel layer 12 and a lower condensed water layer 13 , and the lower condensed water layer 13 is discharged through the drain port 4 .
[0028] Furthermore, a mounting plate 11 is welded to the outer side of the bottom end of the oil tank 1 to facilitate installation and removal of the oil tank 1 , and the cathode terminal 2 and the anode terminal 3 are connected and fixed by a bracket 10 to facilitate installation and removal of the cathode terminal 2 and the anode terminal 3 .
[0029] Finally, it should be noted that the electronic components of the adjustable resistor 6, alarm 7, power supply device 9, etc. involved in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.
[0030] When the automatic drain device of the air compressor oil tank of the utility model is used, first, when the water content in the oil tank 1 is not large, the cathode terminal 2 and the anode terminal 3 are filled with screw oil, and the screw oil is an insulator. At this time, the whole circuit is in a disconnected state, the circuit of the alarm 7 is not connected, and the alarm 7 is in an off state. When the water content of the oil tank 1 gradually increases to above the contact point of the cathode terminal 2 and the anode terminal 3, since the density of water is greater than that of the screw oil, the water will be concentrated at the bottom of the oil tank 1, and the water (non-pure state) is conductive. At this time, the current value set by the control circuit is reached, and the alarm 7 will be turned on at this time, and the alarm 7 is in an alarm state. At this time, just press and hold the button of the electric drain valve switch 8 to make the electric drain valve 5 electrically conductive and start draining. During the draining process, the fuel purity will gradually increase, and the current between the cathode terminal 2 and the anode terminal 3 will become smaller and smaller. When it is lower than the current value set by the control circuit, the control circuit gives a power-off signal, and the alarm 7 is off. At this time, the customer can release the electric drain valve switch 8, and the electric drain valve 5 will be immediately closed.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
