DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0025] Thus, one feature that is described in the specification will be used to illustrate one feature of an embodiment of the application, and is not meant to imply that every embodiment of the application must have that feature. Moreover, it should be noted that the specification describes many features. Although certain features can be combined in one embodiment, these features can also be used in other embodiments that do not explicitly mention the combination. Thus, unless otherwise noted, the combination of features is not intended to limit the application.

[0026] The principle of the present application will be described in detail below in combination with the drawings and embodiments.

[0027] The present application provides a kind of vacuum air liquid separator as shown in Figures 1-4 The vacuum air liquid separator can remove water droplets by gravity settling and baffling separation, preventing water droplets from entering the vacuum pump. The inlet pipe 2 is connected to the vacuum suction for fixing the workpiece through a hose, and the exhaust pipe 3 is connected to the vacuum pump through a hose. The pipe diameter of the liquid separation cylinder 1 is much larger than the hose and the inlet pipe 2. After the gas mixed with fine water droplets enters the liquid separation cylinder 1 from the vacuum suction, it expands rapidly and the flow rate decreases. Part of the water droplets will settle at the bottom of the liquid separation cylinder 1 under the action of gravity, and part of the water droplets will be diverted with the airflow and adhere to the wall of the liquid separation cylinder and then flow to the bottom of the liquid separation cylinder 1. Then it is discharged from the liquid outlet 4. The negative pressure plug 5 is automatically controlled by the vacuum pump. The negative pressure plug 5 automatically blocks the liquid outlet 4. When the vacuum pump stops, the negative pressure plug 5 automatically sinks under the action of gravity, thereby opening the liquid outlet 4 for liquid discharge.

[0028] In this embodiment, one vacuum pump can connect multiple vacuum suctions through the vacuum air liquid separator. The inlet pipe 2 is provided with multiple inlet branch pipes 21, and each inlet branch pipe 21 is provided with an electromagnetic valve 22. When the vacuum pump is pumping, the electromagnetic valve 22 will open the corresponding vacuum suction according to the instruction.

[0029] In this embodiment, the liquid separation cylinder 1 extends transversely, and the inlet pipe 2 and the exhaust pipe 3 are arranged at both ends of the liquid separation cylinder 1. A flow guide column 6 is arranged in the liquid separation cylinder 1. The flow guide column 6 is located in the middle of the liquid separation cylinder 1 and extends along the axial direction of the liquid separation cylinder 1. The flow guide column 6 further forces the airflow entering the liquid separation cylinder 1 to change direction and increases the contact area between the liquid separation cylinder 1 and the airflow, thereby increasing the efficiency of capturing water droplets. The flow guide column 6 is provided with helical fins 7 on the side, so that a helical air duct 8 is formed in the liquid separation cylinder 1. After the airflow enters the liquid separation cylinder 1, it rotates spirally and advances. In the process of continuous turning, the water droplets in the airflow are more easily captured by the wall of the liquid separation cylinder, the flow guide column 6 and the helical fins 7.

[0030] In the embodiment, the inner wall of the liquid separation cylinder 1 is provided with water absorbing lines 11, which can help to capture small water droplets in the air. The inner wall of the liquid separation cylinder 1 is provided with a drainage groove 12 without water absorbing lines 11 at the bottom, which is used to guide the collected water flow to flow out of the drain port. In addition, the liquid separation cylinder 1 is provided with a filter screen 9 near the air inlet pipe 2. When the airflow contacts the filter screen 9, the water droplets with a larger particle size will be intercepted by the filter screen 9. The mesh diameter of the filter screen 9 is not less than 5 mm, so as to avoid affecting the suction force of the vacuum suction.

[0031] In the embodiment, the negative pressure plug 5 includes a plug cover 51, a plug handle 52 and a limiting plate 53. The plug cover 51 is located at the bottom end of the plug handle 52, and the limiting plate 53 is located at the top end of the plug handle 52. The liquid outlet 4 is provided with a sleeve hole 41, and the plug handle 52 is slidingly arranged in the sleeve hole 41. When the vacuum pump is pumping, the flow speed in the liquid separation cylinder 1 on the inner side of the plug cover 51 is faster than the flow speed on the outer side of the plug cover 51. The negative pressure is formed on the inner side of the plug cover 51 to make the plug cover 51 float upwards until the plug cover 51 completely seals the liquid outlet 4. When the vacuum pump stops working, the pressure on both sides of the plug cover 51 is balanced, and the plug cover 51 sinks under the action of gravity until the limiting plate 53 contacts the sleeve hole 41. The top of the plug cover 51 is provided with a sealing block 54, which will be clamped into the liquid outlet 4 when the plug cover 51 seals the liquid outlet 4, so as to avoid air leakage of the liquid outlet 4.

[0032] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
