Description

Technical Field

[0001] The utility model relates to an air-water separator, in particular to an air-water separator, belonging to the technical field of air compressors. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws; air compressors have multiple components, and the air-water separator is one of them, through which the air and water are separated.

[0003] A Chinese public patent (publication number: CN206631338U) discloses an air-water separator for an air compressor, including a tank body and a tank cap. An air outlet pipe coaxial with the tank body is arranged in the tank body, and the lower end of the air outlet pipe extends out of the tank body to form an exhaust port. The tank body is divided into an outer cavity and an inner cavity by the air outlet pipe. A coarse filter plate and a wire mesh demister are arranged at the upper end of the air inlet in the outer cavity. The coarse filter plate and the wire mesh demister are fixed between the outer wall of the air outlet pipe and the inner wall of the tank body through a mounting plate. The gas in the utility model passes through a coarse filter plate and a wire mesh demister for double filtration, and then enters the air outlet pipe from the upper port of the air outlet pipe. The coarse filter plate can filter larger liquid foam in the suspended gas, and the wire mesh demister can filter smaller and tiny liquid foam suspended in the gas. The double filtration can effectively remove moisture in the gas, thereby obtaining relatively dry compressed air, which better plays the role of gas-water separation and improves the cleanliness of the compressed air normally discharged when the compressor is working; however, during use, due to the limited contact area between the gas and the inner wall of the tank body, the gas-water separation effect is greatly reduced. For this reason, a high-efficiency gas-water separator is proposed. Utility Model Content

[0004] In view of this, the utility model provides a gas-water separator to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0005] The technical solution of the utility model is implemented as follows: a gas-water separator comprises a shell assembly, wherein the shell assembly comprises a tank body, an exhaust pipe, a drain pipe, an air inlet pipe, a tank cover and a gas-water contact assembly;

[0006] The top of the tank body is installed with a tank cover by bolts and nuts, the bottom of the tank body is connected with an exhaust pipe, and the upper surface of the exhaust pipe is away from the upper surface of the tank body, one side of the tank body and a position close to the top is connected with an air intake pipe, the bottom of the tank body is connected with a drain pipe near one side, and an air-water contact component is arranged inside the tank body near the top;

[0007] The air-water contact assembly includes a first vertical plate and a second vertical plate. The first vertical plate is fixed at a position close to one side of the top of the tank body, and the second vertical plate is fixed at a position symmetrically distributed about the center line and the first vertical plate inside the tank body.

[0008] Further preferably, a cleaning assembly is provided above the tank cover, the cleaning assembly comprises a bracket, the bracket is fixed at the top of the tank cover, a connecting rod vertically penetrates the middle of the tank cover, and a cylinder for driving the connecting rod to move up and down is installed at the top of the bracket.

[0009] Further preferably, a connecting frame is fixed to the outer wall of the connecting rod below the tank cover, and a scraper 1 is fixed to the bottom end of the connecting frame.

[0010] Further preferably, a scraping ring is fixed at the middle position of the bottom end of the connecting frame, and scraper plates 2 are fixed on both sides of the scraping ring.

[0011] Further preferably, a sewage pipe is connected and fixed at a middle position on one side of the tank body, and a filter is installed at a horizontal position at the bottom end of the sewage pipe inside the tank body.

[0012] Further preferably, the inner wall of the filter screen is tightly fitted with the outer wall of the exhaust pipe, and a distance space is provided between the upper surface of the filter screen and the lower surface of the air-water contact component.

[0013] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0014] 1. After the gas and water enter the tank body of the utility model, the gas and water contact the vertical plate 1 and the vertical plate 2. Since the surface temperature of the vertical plate 1 and the vertical plate 2 is lower than the gas and water temperature, when the gas and water contact the vertical plate 1 and the vertical plate 2, the gas and water separation is accelerated, thereby improving the gas-water separation effect.

[0015] 2. In the utility model, after the gas and water contact the vertical plate 1 and the vertical plate 2, there will be residues contained in the gas on the surface of the vertical plate 1 and the vertical plate 2. After a long time, dirt will accumulate on the surface of the vertical plate 1 and the vertical plate 2, which will affect the later separation of gas and water. The cylinder is used to push the connecting frame up and down, and the scraper 1, the scraper ring and the scraper 2 are used to perform simple scraping treatment on the exhaust pipe, the vertical plate 1 and the surfaces on both sides of the vertical plate 2, thereby realizing the cleaning of the surface of the vertical plate 2 and the vertical plate 1.

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, the embodiment of the utility model provides a gas-water separator including a shell assembly 1, the shell assembly 1 includes a tank body 11, an exhaust pipe 12, a drain pipe 13, an air intake pipe 15, a tank cover 16 and a gas-water contact assembly 4;

[0027] The top of the tank body 11 is installed with a tank cover 16 by bolts and nuts, the bottom of the tank body 11 is connected with an exhaust pipe 12, and the upper surface of the exhaust pipe 12 is away from the upper surface of the tank body 11, one side of the tank body 11 and near the top is connected with an air intake pipe 15, the bottom of the tank body 11 is connected with a drain pipe 13, and the inside of the tank body 11 is provided with an air-water contact component 4 near the top;

[0028] The gas-water contact assembly 4 includes a vertical plate 1 41 and a vertical plate 2 42. The vertical plate 1 41 is fixed at a position near one side of the top of the tank body 11, and the vertical plate 2 42 is fixed at a position symmetrically distributed about the center line and the vertical plate 1 41 in the tank body 11. The gas-water enters through the air inlet pipe 15, and contacts the vertical plate 1 41, the vertical plate 2 42 and the exhaust pipe 12 after entering. Since there is a temperature difference between the gas-water temperature and the vertical plate 1 41, the vertical plate 2 42 and the exhaust pipe 12, the gas-water contacting the surface of the vertical plate 1 41, the vertical plate 2 42 and the exhaust pipe 12 produces liquefaction, thereby accelerating the gas-water liquefaction speed. The liquid flows downward and is discharged from the tank body 11 through the drain pipe 13. The gas rises and finally flows along the exhaust pipe 12, thereby discharging the gas in the tank body 11 through the exhaust pipe 12.

[0029] In one embodiment, a cleaning assembly 2 is disposed above the tank cover 16, and the cleaning assembly 2 includes a bracket 22, the bracket 22 is fixed at the top of the tank cover 16, a connecting rod 23 is vertically penetrated at the middle of the tank cover 16, and a cylinder 21 for driving the connecting rod 23 to move up and down is installed at the top of the bracket 22. The connecting frame 24 moves up and down through the cylinder 21, and when it is necessary to clean the surface of the vertical plate 1 41 and the vertical plate 2 42, the cylinder 21 is started, and the cylinder 21 is expanded and contracted to drive the connecting rod 23 to move up and down.

[0030] In one embodiment, a connecting frame 24 is fixed to the outer wall of the connecting rod 23 below the tank cover 16, and a scraper 1 25 is fixed to the bottom end of the connecting frame 24. During the lifting and lowering process of the connecting frame 24, the scraper 1 25 can clean the particle dirt attached to the upper side of the vertical plate 2 42 and the vertical plate 1 41 away from each other, thereby improving the subsequent separation effect of the vertical plate 1 41 and the vertical plate 2 42 on gas and water.

[0031] In one embodiment, a scraper ring 26 is fixed at the middle position of the bottom end of the connecting frame 24, and two scrapers 27 are fixed on both sides of the scraper ring 26. The inner wall of the scraper ring 26 and the outer wall of the exhaust pipe 12 are closely fitted, and the scraper ring 26 can be used to clean the outer wall of the exhaust pipe 12, thereby achieving a cleaning effect on the outer wall of the exhaust pipe 12, and at the same time, the scraper 27 is used to clean the side of the vertical plate 2 42 and the vertical plate 1 41 that are close to each other.

[0032] In one embodiment, a sewage pipe 14 is connected and fixed at the middle position of one side of the tank body 11, and a filter screen 3 is installed at the bottom horizontal position of the sewage pipe 14 inside the tank body 11. The filter screen 3 can filter the granular residue contained in the gas to improve the cleanliness of the liquid.

[0033] In one embodiment, the inner wall of the filter screen 3 is closely attached to the outer wall of the exhaust pipe 12, and a distance space is provided between the upper surface of the filter screen 3 and the lower surface of the gas-water contact assembly 4. This prevents the liquid from being higher than the filter screen 3 and contacting the bottom of the vertical plate 1 41 and the vertical plate 2 42, thereby reducing the gas flow space.

[0034] When the utility model is working, gas and water enter the tank body 11 through the air inlet pipe 15, and the gas and water contact the surface of the vertical plate 1 41, the vertical plate 2 42 and the exhaust pipe 12, and the temperature difference accelerates the formation of liquid. The liquid flows under the action of gravity, and the liquid passes through the filter screen 3 to filter the residue in the liquid. Then the liquid flows out through the drain pipe 13, while the gas rises and is finally discharged from the tank body 11 through the exhaust pipe 12 to achieve gas-water separation. Later, when Xu Ya cleans the surface of the vertical plate 1 41, the vertical plate 2 42 and the exhaust pipe 12, the bracket 22 is started, and the bracket 22 unfolds the connecting rod 23 and the connecting frame 24 and moves downward, and the vertical plate 1 41, the vertical plate 2 42 and the exhaust pipe 12 are simply cleaned by the scraper 1 25, the scraper ring 26 and the scraper 27.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
