Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor oil-gas separation cylinder with a defoaming device. Background Art

[0002] The existing air compressor oil-gas separation cylinder generally includes an outer cylinder, an oil-gas separator core is arranged in the upper part of the outer cylinder, an inner cylinder is arranged in the middle part of the outer cylinder, the upper end of the outer wall of the inner cylinder is fixed to the inner wall of the outer cylinder through an annular baffle, and an inlet pipe is passed through the outer cylinder, and the inner end of the inlet pipe is located in the channel between the outer wall of the inner cylinder and the inner wall of the outer cylinder. The lower cavity of the outer cylinder uses the spatial structure to perform the initial separation of the oil-gas mixture, and the upper light body of the outer cylinder uses the oil-gas separator core for secondary separation. For the initial separation of the oil-gas mixture, the oil-gas mixture enters the outer cylinder and rotates around the outer wall of the inner cylinder and moves downward. In this process, the oil with a larger specific gravity settles to the bottom of the outer cylinder, and the remaining oil-gas mixture rotates downward to the bottom of the inner cylinder, and then flows upward from the inside of the inner cylinder until it passes through the inner cylinder and enters the upper cavity for secondary separation. Since the oil-gas mixture flows at a high speed, it will continue to flow downward for a distance after rotating to the bottom of the inner cylinder, which can easily impact the oil surface at the bottom of the outer cylinder to generate bubbles, greatly affecting the initial separation effect of the oil and gas. Summary of the invention

[0003] The utility model aims to provide an air compressor oil-gas separation cylinder with a defoaming device, which can solve the technical problems mentioned in the background technology.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: an air compressor oil-gas separation cylinder with a defoaming device, comprising an outer cylinder, an oil-gas separator core is arranged in the upper part of the outer cylinder, an inner cylinder is arranged in the middle part of the outer cylinder, the upper end of the outer wall of the inner cylinder is fixed to the inner wall of the outer cylinder by an annular baffle, an inlet pipe passes through the outer cylinder, the inner end of the inlet pipe is located in the channel between the outer wall of the inner cylinder and the inner wall of the outer cylinder, a defoaming plate is vertically arranged in the lower part of the outer cylinder and is located below the inner cylinder, the two horizontal ends of the defoaming plate are connected to the inner wall of the outer cylinder, a gap is left between the lower end of the defoaming plate and the bottom of the outer cylinder, and a plurality of defoaming holes are opened on the defoaming plate.

[0005] Preferably, the plurality of degassing holes are divided into two rows and distributed vertically.

[0006] Preferably, the pore diameter of the degassing holes in the upper row is larger than the pore diameter of the degassing holes in the lower row.

[0007] Preferably, the center line of the inlet pipe is tangent to the center line of the channel, and the defoaming plate is away from the center line of the outer cylinder and is skewed and perpendicular to the center line of the inlet pipe.

[0008] Preferably, a sewage outlet is provided at the bottom of the outer cylinder.

[0009] Preferably, an L-shaped oil outlet pipe is provided in the lower part of the outer cylinder, one end of the oil outlet pipe is located at the bottom of the outer cylinder, and the other end of the oil outlet pipe extends out of the outer cylinder.

[0010] Preferably, a connecting flange is provided at the outer end of the inlet pipe.

[0011] Compared with the prior art, the beneficial effect of the utility model lies in that a debubbling plate is provided in the lower part of the outer cylinder of the utility model, and a plurality of debubbling holes are provided on the debubbling plate. When the oil-gas mixture rotates downward at a high speed, it will be blocked by the debubbling plate and then pass through the debubbling holes. Even if bubbles are generated, the bubbles will burst and disappear due to the blocking of the debubbling plate, thereby greatly improving the oil-gas separation effect, and the structure is simple and the cost is low.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1-Figure 5 As shown, the utility model provides an air compressor oil-gas separation cylinder with a defoaming device, comprising an outer cylinder 1, an oil-gas separator core is arranged in the upper part of the outer cylinder 1, an inner cylinder 2 is arranged in the middle part of the outer cylinder 1, the upper end of the outer wall of the inner cylinder 2 is fixed to the inner wall of the outer cylinder 1 through an annular baffle 3, an inlet pipe 4 passes through the outer cylinder 1, the inner end of the inlet pipe 4 is located in the channel between the outer wall of the inner cylinder 2 and the inner wall of the outer cylinder 1, a defoaming plate 5 located below the inner cylinder 2 is vertically arranged in the lower part of the outer cylinder 1, the two lateral ends of the defoaming plate 5 are connected to the inner wall of the outer cylinder 1, a gap is left between the lower end of the defoaming plate 5 and the bottom of the outer cylinder 1, and a plurality of defoaming holes 6 are opened on the defoaming plate 5.

[0019] When the utility model is in use, the oil-gas mixture enters the channel between the inner cylinder 2 and the outer cylinder 1 from the inlet pipe 4, and then rotates around the outer wall of the inner cylinder 2 and moves downward, and the oil with a larger specific gravity settles to the bottom of the outer cylinder 1, completing the initial separation of the oil-gas mixture. Because there is a gap between the debubbling plate 5 and the bottom of the outer cylinder 1, the oil on both sides of the debubbling plate 5 can communicate with each other through the gap. After the remaining oil-gas mixture rotates downward to the bottom of the inner cylinder 2, it flows upward from the inside of the inner cylinder 2 until it passes through the inner cylinder 2 and enters the upper cavity, and is separated twice by the oil-gas separator core. When the oil-gas mixture rotates downward at a high speed, it will be blocked by the debubbling plate 5, and then pass through the debubbling hole 6. Even if bubbles are generated, the bubbles will break and disappear due to the blocking of the debubbling plate 5, which greatly improves the oil-gas separation effect, and the structure is simple and the cost is low.

[0020] Preferably, the plurality of degassing holes 6 are divided into two rows and distributed up and down, and the aperture of the degassing holes 6 in the upper row is larger than the aperture of the degassing holes 6 in the lower row, so that the degassing effect is better.

[0021] Preferably, the center line of the inlet pipe 4 is tangent to the center line of the channel. Since the flow velocity of the oil-gas mixture is relatively high, the oil-gas mixture will generate centrifugal force when entering the channel tangentially, and the initial separation effect is good. The defoaming plate 5 is away from the center line of the outer cylinder 1 and is eccentrically perpendicular to the center line of the inlet pipe 4. After centrifugal movement, the oil-gas mixture can directly rush into the defoaming plate 5, thereby achieving a good defoaming effect.

[0022] Preferably, a sewage outlet 7 is provided at the bottom of the outer cylinder 1 , and dirt deposited at the bottom of the outer cylinder 1 can be discharged from the sewage outlet 7 .

[0023] Preferably, an L-shaped oil outlet pipe 8 is provided in the lower part of the outer cylinder 1, one end of the oil outlet pipe 8 is located at the bottom of the outer cylinder 1, and the other end of the oil outlet pipe 8 extends out of the outer cylinder 1 to facilitate oil extraction.

[0024] Preferably, a connecting flange 9 is provided at the outer end of the inlet pipe 4 for easy installation.

[0025] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and the implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
