Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of air compressor field, specifically to a kind of air compressor gas-water separator. BACKGROUND

[0002] Air compressor (air compressor) is a kind of equipment that converts mechanical energy into gas pressure energy, mainly used for compressed air for various industrial and commercial applications. The gas discharged by air compressor is saturated compressed air containing a large amount of water vapor, so the water and oil in the compressed air need to be separated before discharge to ensure dry and clean air.

[0003] The more common gas-water separator currently includes inertial separation, filter separation or centrifugal separation. Inertial separation uses the inertia of air flow to make water droplets and oil droplets collide with the separator wall, and then condense and discharge. Filter separation further filters small water droplets and oil droplets through filter core or filter screen. Centrifugal separation uses high-speed rotation to separate water droplets and oil droplets under the action of centrifugal force.

[0004] Among them, the centrifugal separator is more suitable for large flow occasions due to its high separation efficiency. However, when the internal liquid volume in the separation tank is too large, it needs to be discharged. But during the discharge process, the internal liquid is completely discharged, and then the gas leaks from the drain. If the gas delivery is stopped first and then discharged, it will affect the gas-water separation efficiency of the air compressor. And most gas-water separators only have one gas-water separation structure, which can easily lead to general gas-water separation effect, and the discharged gas still contains a lot of water. Therefore, a gas-water separator that can discharge too much internal liquid intelligently without stopping gas delivery and causing gas leakage, and has good gas-water separation effect is needed.

The present application will be described in detail below with reference to the drawings Figures 1-4 The present application will be described in detail below with reference to the drawings

[0023] A kind of air compressor gas-water separator, including shell 1, shell 1 top wall and bottom wall are provided with servo motor 10 and support column 11 respectively, support column 11 is used to support the whole device, servo motor 10 is used to drive rotating drum 9 rotation realizes gas-water centrifugal separation, still be provided with deslagging pipe 12 in shell 1 bottom wall, the bottom wall of deslagging pipe 12 is movably provided with screw cap, deslagging pipe 12 is used to stop gas transmission periodically, unscrew screw cap, all liquid in the inside of shell 1 is discharged to outside once, when not needing to stop gas transmission, screw cap is tightened, deslagging pipe 12 is in closed state, i.e. the liquid that can be discharged in the accumulation above water flow pass-through 13 in the bottom of shell 1.

[0024] Deslagging pipe 12 is used to stop gas transmission periodically, unscrew screw cap, all liquid in the inside of shell 1 is discharged to outside once, when not needing to stop gas transmission, screw cap is tightened, deslagging pipe 12 is in closed state, i.e. the liquid that can be discharged in the accumulation above water flow pass-through 13 in the bottom of shell 1.

[0025] Shell 1 top wall and side wall are fixedly provided with baffle 5, baffle 5 includes two pieces of vertical direction and horizontal direction, the inner wall of baffle 5 close to the side of inlet pipe 2 is movably placed with adsorption net 6, the side of vertical direction baffle 5 close to inlet pipe 2 is fixedly provided with U-shaped groove plate 14, the top end of U-shaped groove plate 14 is fixedly provided with through slot 15 in the top wall of shell 1, the outer wall of through slot 15 is movably provided with cover plate 16, adsorption net 6 is movably placed on U-shaped groove plate 14.

[0026] The bottom wall of the cover plate 16 is provided with a sealing ring matched in size with the through slot 15, so that gas leakage can be avoided. The top wall of the shell 1 and the cover plate 16 are provided with a plurality of connecting blocks which can be fastened or detached by a bolt assembly, so that the cover plate 16 can be fixed on or detached from the top wall of the shell 1. The adsorption net 6 can be made of activated carbon or sponge material, and has water absorption and can remove impurities in the gas. The cover plate 16 can be opened regularly to clean or replace the adsorption net 6.

[0027] The gas flow port 7 and the water level sensor 8 are sequentially arranged below the adsorption net 6, and the water level sensor 8 is arranged below the gas flow port 7. The mixed gas enters from the gas inlet pipe 2 and hits the adsorption net 6. The adsorption net 6 can adsorb water and impurities in the mixed gas. The remaining gas enters the rotating drum 9 on the other side from the gas flow port 7. After the adsorption net 6 adsorbs a large amount of water, water droplets are formed and fall to the bottom of the shell 1.

[0028] The rotating drum 9 includes a central shaft 17 rotatably arranged between the top wall of the shell 1 and the horizontal partition plate 5, and the central shaft 17 is fixedly arranged on the output end of the servo motor 10. The outer wall of the central shaft 17 is fixedly provided with an outer cylinder 18.

[0029] The servo motor 10 is started to drive the central shaft 17 to rotate, thereby driving the outer cylinder 18 to rotate. The gas coming from the gas flow port 7 can collide with the outer cylinder 18 or the side wall of the partition plate 5 and the inner wall of the shell 1 to form a centrifugal motion. The water droplets fall to the bottom of the shell 1 below, and the gas moves upward to the exhaust pipe 3 and is discharged to the outside.

[0030] The other partition plate 5 is at the same height as the water level sensor 8, and the rotating drum 9 is rotatably arranged between the other partition plate 5 and the top wall of the shell 1. The electromagnetic valve 20 is fixedly arranged in the drain pipe 4. The horizontal partition plate 5 is at the same horizontal plane as the water level sensor 8.

[0031] Since the control panel 19 is fixedly arranged on the outer wall of the shell 1, the control panel 19 is electrically connected with the water level sensor 8, the servo motor 10 and the electromagnetic valve 20. Therefore, when the liquid in the bottom of the shell 1 accumulates more and more, the water level slowly rises until it reaches the position of the water level sensor 8. After the water level sensor 8 senses the water level, it transmits the sensing information to the control system in the control panel 19. Since all operation steps are predetermined on the control system, when it receives the information, it instructs the electromagnetic valve 20 to open, opens the drain pipe 4, and allows the water flow to be discharged from the drain pipe 4.

[0032] Since the lowest end of the drain pipe 4 is higher than the bottom wall of the vertical partition plate 5 and the highest end is lower than the bottom end of the water level sensor 8, and a water flow passage 13 is arranged between the bottom wall of the vertical partition plate 5 and the bottom wall of the shell 1, the drain pipe 4 can only drain the water flow higher than the bottom wall of the vertical partition plate 5 and cannot drain the water in the water flow passage 13, so the mixed gas cannot directly leak from the water flow passage 13 but flows into the centrifugal separation position of the rotating drum 9 through the gas flow passage 7, and the gas supply channel can be unnecessary to be closed.

[0033] When the electromagnetic valve 20 senses that there is no water flow, the control panel 19 controls the electromagnetic valve 20 to be closed, so that the drain pipe 4 is closed and the water flow is newly gathered.

[0034] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
