Abstract
Description
Technical Field
[0001] This utility model relates to the field of air compressor storage tank drainage technology, specifically an automatic condensate discharge device for air compressor storage tanks. Background Technology
[0002] An automatic condensate drain device for air compressor receiver tanks is a device used to automatically remove condensate generated in compressed air systems. It aims to ensure the receiver tank is dry and clean, preventing problems such as corrosion, blockage, or pneumatic component malfunctions caused by water accumulation. One existing automatic drain device uses a float that rises and falls with the water level to trigger the drain action. When the water level rises to a specific position, the float rises, the drain port opens, and water is discharged. When the water level drops, the float falls, blocking the drain port.
[0003] The automatic drainage device's pipe is connected to the drain outlet at the bottom of the air compressor's air tank. Due to the weight of the drainage device and the force of the water being drained, the device tends to shake. Over time, this causes wear and tear on the pipes, reducing their lifespan. Therefore, an automatic condensate drain device for the air compressor's air tank is needed to solve this problem. Utility Model Content

[0028] The outlet pipe 10 provides a discharge channel for the condensate in the gas storage tank. The pre-filter 11 plays a filtering role to prevent the drain pipe 13 on the side of the drain tank 12 from clogging and affecting drainage. The drain tank 12 has an automatic drainage function, and the drain pipe 13 is used to discharge the water in the drain tank 12.
[0029] The support assembly includes a first support rod 21, a second support rod 24, a support tube 25, and an adjusting rod 26. The two ends of the first support rod 21 are fixed to the bracket at the lower end of the gas storage tank. The second support rod 24 is fixed to the middle of the side of the first support rod 21. The lower end of the support tube 25 is fixed above the other end of the second support rod 24 away from the first support rod 21. The lower end of the adjusting rod 26 is screwed into the support tube 25.
[0030] The support assembly also includes an opening 20, a waist hole 22 and a bolt 23. The opening 20 is opened on the bracket at the lower end of the gas storage tank, and the first support rod 21 is inserted into the opening 20. The waist hole 22 is opened at both ends of the first support rod 21, and the bolt 23 is fixed in the waist hole 22.
[0031] The support assembly also includes a rubber pad 27, which is fixed to the top of the adjusting rod 26 and fits against the lower end of the water outlet pipe 10.
[0032] The opening 20 serves as a connection, the first support rod 21 and the second support rod 24 serve as supports, the waist hole 22 serves as a connection, the bolt 23 serves as a fixation, the support tube 25 serves as a support, the adjusting rod 26 can adjust the height, and the rubber pad 27 serves as a support.
[0033] Working principle:
[0034] Insert the first support rod 21 into the opening 20, insert the bolt 23 into the waist hole 22 and make it fit against the opening 20, tighten the nut, rotate the adjusting rod 26 on the other end of the second support rod 24 support tube 25 to drive the rubber pad 27 to rise until the rubber pad 27 fits against the lower end of the water outlet pipe 10 near the drain tank 12.
[0035] This step can prevent the water outlet pipe 10 from being affected by the gravity of the drain tank 12, and reduce the shaking frequency caused by the impact of water flow.
[0036] Please see Figure 2-3 As shown, this embodiment, based on the above embodiment, further includes:
[0037] The movable component includes a fixed plate 30, a connecting shaft 31, a through hole 32, and a T-shaped insert 33.

[0038] The T-shaped insert 33 is inserted between the first support rod 21 and the second support rod 24, and its side is attached to the other end of the second support rod 24 away from the support tube 25;
[0039] The fixed plate 30 provides support, the connecting shaft 31 facilitates the rotation of the second support rod 24, the through hole 32 provides connection, and the T-shaped insert 33 provides a limiting function.
[0040] Working principle:
[0041] After a period of use, it is necessary to drain the impurities from the pre-filter 11 and pull out the T-shaped insert 33 from the through hole 32. At this time, the second support rod 24 will rotate and fall around the connecting shaft 31 under the gravity of the support tube 25. Open the drain port at the lower end of the pre-filter 11, clean the internal filter screen, and then reinstall it. Lift the second support rod 24 with one hand and insert the T-shaped insert 33 into the through hole 32.
[0042] This step facilitates the removal of the second support rod 24, support tube 25, and adjusting rod 26, avoiding interference with the cleaning of the pre-filter 11.
