Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the trap device according to the embodiment of the present invention is connected to a vacuum pump 300 to remove impurities in the air sucked into the vacuum pump 300.

3, the trap device 200 includes a housing 210, an inlet pipe 220, a trap oil 230, and a filter material 240.

The housing 210 is formed in a cylindrical shape and is mounted on the lower frame 110, and a plurality of compartments 211 are formed therein. The plurality of compartments 211 are vertically positioned and connected to each other to form one passage. The adjacent compartments 211 are connected to each other through the communication port 212. The communication ports 212 formed at the upper and lower portions of the compartment 211 are spaced apart from each other So as to maximize the travel distance of the air through the internal passage of the trap device 200. [ Accordingly, the air passing through the inside of the housing 210 moves upward in a zigzag fashion.

The inlet pipe 220 is a passage through which the internal air of the vacuum object flows into the interior of the housing 210. The inlet pipe 220 extends from the upper portion of the housing 210 to the inside of the housing 210 and extends to the compartment 211 located at the lowermost end of the housing 210. That is, air introduced into the housing 210 through the inflow pipe 220 is transferred to the lowermost compartment 211 of the housing 210, and the air flows from the lowermost compartment 211 of the housing 210 to the uppermost compartment 211 211). The uppermost compartment 211 of the housing 210 is connected to the suction pipe 311 of the vacuum pump 300 so that air having passed through the trap device 200 is sucked into the vacuum pump 300.

As shown in FIG. 3, the trap oil 230 may be charged into at least two compartments 211 including the lowermost compartment 211. The trap oil 230 primarily serves to remove foreign substances contained in the air.
The air flowing into the lowermost stage compartment 211 of the housing 210 through the inlet pipe 220 passes through the trap oil 230 and moves to the upper compartment 211. 3, a communication port 212 for connecting the plurality of compartments 211 including the compartment 211 in which the trap oil 230 is charged is connected to the right and left sides And the air passing through the trap oil 230 filled in the at least two compartments including the lowermost compartment 211 of the housing 210 moves up and down along the communication hole formed to be staggered to the left and right. Since the air flowing into the trap device 200 rises while passing through the trap oil 230, foreign substances can be effectively removed.

The filter medium 240 is inserted into the compartment 211 located at the lower portion of the uppermost compartment 211 of the housing 210 as shown in Fig. Unlike the embodiment shown in the figures, the filter media 240 may be inserted into the other compartment 211. The filter material 240 removes foreign matter remaining in the air after the air passes through the trap oil 230. In addition, the filter medium 240 may be in contact with the air to separate water or oil contained in the air.

2 to 5, the vacuum pump water desorption system including the trap device includes the fixed frames 110, 120 and 130, the trap device 200, the vacuum pump 300 and the auxiliary vacuum pump 400, .

2, a trap device 200, a vacuum pump 300, and an auxiliary vacuum pump 400 are mounted on the fixed frames 110, 120, and 130, respectively. More specifically, the fixed frame includes a lower frame 110 on which the trap device 200 and the auxiliary vacuum pump 400 are mounted, an upper frame 120 on which the vacuum pump 300 is mounted, a lower frame 110, And a support frame 130 for supporting the upper frame 120. The lower frame 110 is equipped with a plurality of wheels for easily moving the fixed frame.

The trap device 200 is connected to the vacuum pump 300 to remove impurities in the air sucked into the vacuum pump 300. Since the trap device 200 has been described above, a detailed description thereof will be omitted.

The vacuum pump 300 sucks air from a vacuum object and forms a negative pressure inside the vacuum object. The vacuum pump 300 may be divided into a compression case 310 and an oil case 320 as shown in FIG.

The compression case 310 is connected to the suction pipe 311 to suck air. Specifically, the suction pipe 311 is connected to the trap device 200, and air having passed through the trap device 200 is sucked into the compression case 310 through the suction pipe 311.

The air sucked into the compression case 310 is compressed by a rotor (not shown) and a rotor vane (not shown) and transferred to the oil case 320. However, the present invention is not limited to this specific type of vacuum pump 300, and can be applied to various types of vacuum pumps 300. [0053] FIG.

Oil is stored in the oil case 320, and the discharge pipe 321 is connected to discharge air from the compression case 310. The oil stored in the oil case 320 functions as lubrication, cooling, and the like.

The discharge pipe 321 is provided with a check valve for preventing the backward flow of the air discharged to the outside through the discharge pipe 321.

On the other hand, the air sucked from the vacuum object may contain moisture, and air containing moisture condenses inside the vacuum pump 300. That is, the moisture in the air transferred to the oil case 320 is condensed to generate condensed water and mixed with the oil stored in the oil case 320. If the condensed water is mixed with the oil, the vacuum pump 300 may be damaged.

The auxiliary vacuum pump 400 sucks the internal air of the vacuum pump 300. That is, as shown in FIG. 5, the auxiliary vacuum pump 400 is connected to the discharge pipe 321 by the connection pipe 410 to suck in the air inside the oil case 320.

When the internal pressure of the oil case 320 is lowered by the auxiliary vacuum pump 400, the condensed water generated by condensation in the oil case 320 is vaporized and is supplied to the vacuum pump 300 by the auxiliary vacuum pump 400. As shown in FIG.

Since the internal pressure of the oil case 320 is lowered by the auxiliary vacuum pump 400, the condensed water generated by condensation in the oil case 320 can be easily vaporized and the suction of the auxiliary vacuum pump 400 The moisture contained in the air can be discharged to the outside.

The vacuum pump water removal system according to the present invention is not limited to the above-described embodiments and can be variously modified within the scope of the technical idea of the present invention.
