[0022] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0025] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] The present application provides an air compressor air tank, which provides an opening and closing signal to the electric-controlled ball valve through the pressure contact of the water float on the upper water level sensor and the lower water level sensor, thereby realizing automatic drainage of the air tank, reducing the workload of the staff and the time consumed in managing the air tank. Furthermore, the present application dries the moist air in the air storage chamber through a drying mechanism, thereby keeping the air storage chamber dry and increasing the service life of the air storage tank. In addition, the present application also intuitively displays the upper and lower pressure differences of the air storage chamber through a pressure differential switch, and judges the water level in the air storage chamber by the pressure differential, making it convenient for the staff to determine whether to manually drain the water.

[0027] like Figure 1 and 2 As shown, the air compressor tank 10 provided in this application has an air inlet pipe 13 at the top and an air outlet pipe 19 at the bottom, and a pressure gauge 15 is provided on the air compressor tank 10. A plurality of brackets 12 are symmetrically arranged on the bottom surface of the air compressor tank 10, so that there is a certain space between the bottom surface of the air compressor tank 10 and the ground.

[0028] like Figure 3 As shown, an upper water level sensor 22 and a lower water level sensor 20 are provided on the inner wall of the air storage chamber 11 of the air compressor air storage tank 10. A water float 21 is provided in the air storage chamber 11. The upper water level sensor 22 and the lower water level sensor 20 are in the movement path of the water float 21. The height of the upper water level sensor 22 is lower than the air outlet pipe 19.

[0029] like Figure 2 and 3 As shown, the bottom of the air compressor air tank 10 is connected to an automatic water outlet pipe 23 that passes through the air storage chamber 11. An electric control ball valve 24 is provided on the automatic water outlet pipe 23. The actuator of the electric control ball valve 24 is electrically connected to the upper water level sensor 22 and the lower water level sensor 20 respectively.

[0030] When the water level in the air storage chamber 11 rises, the water float 21 moves upward under the action of buoyancy. When the water float 21 contacts the upper water level sensor 22, the upper water level sensor 22 senses the contact with the water float 21 and sends a signal to the electric ball valve 24, which controls the electric ball valve 24 to open. The electric ball valve 24 automatically opens, and the automatic water outlet pipe 23 is now connected to the outside world. The accumulated water in the air storage chamber 11 flows out of the air compressor air tank 10 through the automatic water outlet pipe 23. When the accumulated water in the air storage chamber 11 slowly flows out of the air compressor air tank 10 through the automatic water outlet pipe 23, the water float 21 gradually moves downward with the accumulated water until the accumulated water in the air storage chamber 11 is completely discharged from the air compressor air tank 10. At this time, the water float 21 contacts the lower water level sensor 20, and the lower water level sensor 20 sends a signal to the electric ball valve 24, which controls the electric ball valve 24 to close, thereby completing the automatic drainage work.

[0031] Preferably, a vertical guide groove is provided on the inner wall of the air storage chamber 11, and the water float 21 is limited in the guide groove. The upper water level sensor 22 and the lower water level sensor 20 are respectively arranged at the upper end and the lower end of the guide groove, thereby preventing the water float 21 from floating freely in the air storage chamber 11 and being unable to abut against the upper water level sensor 22 and the lower water level sensor 20, causing automatic drainage failure.

[0032] On the basis of the above, preferably, the air compressor tank 10 is also provided with a manual drainage mechanism. Figure 1-2 As shown, the bottom of the air compressor air storage tank 10 is connected to a manual water outlet pipe 25 that passes through the air storage chamber 11 , and a manual valve 26 is provided on the manual water outlet pipe 25 .

[0033] Preferably, if Figure 1 and 2 As shown, the upper and lower ends of the air compressor air tank 10 are respectively equipped with an upper pressure detection tube 17 and a lower pressure detection tube 18 that pass through the air storage chamber 11. The ends of the upper pressure detection tube 17 and the lower pressure detection tube 18 are respectively connected to the two ends of the differential pressure switch 16. The differential pressure switch 16 is equipped with a display screen for displaying the pressure difference between the air pressure detected by the upper pressure detection tube 17 and the lower pressure detection tube 18. The pressure difference allows the operator to determine whether the water in the air storage chamber 11 has reached the upper water level sensor 22.

[0034] When the water in the air storage chamber 11 does not reach the upper water level sensor 22, the staff can choose to drain the water manually. At this time, if the air storage chamber 11 needs to be drained, the staff can manually open the manual valve 26, and the water in the air storage chamber 11 will be discharged from the air compressor air tank 10 through the manual water outlet pipe 25.

[0035] Preferably, a drying mechanism is provided on the outside of the air compressor air storage tank 10 , and the output end of the drying mechanism is connected to the air storage chamber 11 through a drying air duct 14 .

[0036] As an example, Figure 1 and 2 As shown, a horizontal support plate 27 is fixed to the outside of the air compressor tank 10. The drying mechanism includes a fan 29 and a heater box 28, which are positioned on the support plate 27. The output end of the fan 29 is connected to the air inlet of the heater box 28, and the air outlet of the heater box 28 is connected to the air inlet end of the drying air duct 14.

[0037] After completing automatic or manual drainage, start the heating box 28, the heating box 28 heats the air, and the fan 29 is started. The fan 29 blows the gas heated by the heating box 28 into the air storage chamber 11. The air heated by the heating box 28 heats and dries the air in the air storage chamber 11 until all the water vapor in the air storage chamber 11 is discharged outside the air compressor air tank 10, keeping the air in the air storage chamber 11 dry.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
