[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] Embodiment 1:

[0020] Depend on Figures 1 to 3 It is given that the utility model includes a tank body 1 and a tank cover 2, the tank cover 2 is sealed and fixedly installed on the upper end of the tank body 1, one side of the tank body 1 is provided with one or more air inlets 3, the other side of the tank body 1 is provided with a vacuum port 4, the vacuum port 4 is connected to the vacuum pump through a vacuum pipeline, a dust removal isolation cover is also provided between the air outlet and the air inlet 3, the lower end of the dust removal isolation cover is lower than the vacuum port 4 and is provided with a through port 5 connected to the vacuum port 4, the lower end of the tank body 1 is also provided with an oil port 6, and vacuum oil that does not pass through the through port 5 is also provided in the tank body 1, a valve is provided at the oil port 6, and the vacuum oil can enter or discharge the tank body 1 through the oil port 6.

[0021] It can be understood that the gas entering the tank body 1 through the air inlet 3 needs to pass through the dust removal isolation cover before entering the vacuum port 4, and the impurities carried in the gas are blocked by the dust removal isolation cover and fall on the surface of the vacuum oil. When too many impurities accumulate on the surface of the vacuum oil, they can be directly discharged through the oil port 6, and the treated vacuum oil can still be used.

[0022] Specifically, the dust removal isolation cover includes a horizontal dust removal cloth 7 and a vertical dust removal cloth 8. The horizontal dust removal cloth 7 is fan-shaped, and the vertical dust removal cloth 8 is rectangular. The horizontal dust removal cloth 7 is located on the upper side of the air inlet 3, and the vertical dust removal cloth 8 is located between the vacuum port 4 and the air inlet 3. The upper end of the vertical dust removal cloth 8 is connected to the end of the horizontal dust removal cloth 7 away from the air inlet 3, and the horizontal dust removal cloth 7 and the vertical dust removal cloth 8 are fixedly connected to the inner wall of the tank body 1.

[0023] In order to enable the horizontal dust-removing cloth 7 and the vertical dust-removing cloth 8 to be installed on the inner wall of the tank body 1, and to ensure the dust-removing sealing performance of the dust-removing isolation cover formed by the horizontal dust-removing cloth 7 and the vertical dust-removing cloth 8, the tank body 1 is provided with a horizontal arc groove 9 and two vertical grooves 10 fixedly arranged on the inner wall of the tank body 1. The two pairs of vertical grooves 10 are symmetrically arranged about the vacuum port 4 and the air inlet 3. The upper ends of the two vertical grooves 10 are connected to the two ends of the arc groove 9. The horizontal dust-removing cloth 7 is fixedly installed in the arc groove 9, and the two side surfaces of the vertical dust-removing cloth 8 are respectively installed in the two vertical grooves 10. A plurality of threaded holes are provided on the arc groove 9 and the two vertical grooves 10, and a screw rod 11 is threadedly installed in each threaded hole. A pressure plate is installed at one end of the screw rod extending into the arc groove 9 or the vertical groove 10. The threaded groove is rotated to make the screw rod 11 extend into the arc groove 9 or the vertical groove 10, and the dust-removing cloth is pressed by the pressure plate.

[0024] It should be noted that the oil port 6 is detachably connected to the pump body. When the vacuum oil in the tank body 1 is not enough to cover the through port 5, the pump body can deliver vacuum oil into the tank body 1 through the oil port 6, or after opening the tank cover 2, the vacuum oil can be directly injected into the tank body 1.

[0025] In addition, the tank body 1 is also provided with an observation port 12 , the height of which is higher than the through port 5 , so that the remaining amount of vacuum oil in the tank body 1 can be observed at any time through the observation port 12 to determine whether the vacuum oil has submerged the through port 5 .

[0026] Specifically, the upper end of the tank body 1 is provided with a first flange 13 , the tank cover 2 is provided with a second flange 14 matched with the first flange 13 , the first flange 13 is further provided with an annular groove 15 , and a sealing ring is provided in the annular groove 15 .

[0027] When the utility model is in use, the air inlet 3 is connected to the welding furnace, and the vacuum pump extracts the gas in the welding furnace through the vacuum port 4. The gas carrying impurities passes through the dust removal isolation cover and enters the vacuum port 4. The impurities in the gas are blocked by the dust removal isolation cover and fall into the vacuum oil for collection.

[0028] The beneficial effects of the utility model are:

[0029] (1) A dust removal isolation cover is arranged inside the tank body to form a space with filtering function inside the tank body, which has good filtering effect and is easy to use;

[0030] (2) The vacuum oil containing impurities can be discharged through the valve of the oil port, and vacuum oil can be added to maintain the filtering function. The vacuum oil can be reused, which reduces the processing cost and improves the utilization rate of materials;

[0031] (3) The condition of the vacuum oil in the furnace can be observed in real time through the observation port, so that the vacuum oil can be replenished at any time. It is highly flexible and easy to use.
