[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 The utility model provides an embodiment: a pollutant purification device for an EB furnace, comprising a connecting box 1, the outer wall of the connecting box 1 is rotatably connected to a handle 2, the outside of the handle 2 is fixedly connected to a screw rod 3, one end of the screw rod 3 is fixedly connected to a limiting plate 4, the outer wall of the screw rod 3 is threadedly connected to a threaded sleeve 5, the inside of the threaded sleeve 5 is rotatably connected to a rotating shaft 1 6, the outer wall of the rotating shaft 1 6 is fixedly connected to a turntable 7, the inside of the turntable 7 is rotatably connected to a rotating shaft 2 8, the outer wall of the rotating shaft 2 8 is fixedly connected to a sliding sleeve 9, the inside of the sliding sleeve 9 is slidably connected to a sliding rod 10, the inside of the sliding rod 10 is rotatably connected to a rotating shaft 3 11, the outer wall of the rotating shaft 3 11 is fixedly connected to a clamping block 12, the inside of the sliding rod 10 is rotatably connected to a rotating rod 13, the outer wall of the rotating rod 13 is fixedly connected to a base 14, and an exhaust assembly is provided on the upper surface of the turntable 7.

[0024] Specifically, by rotating the handle 2, the threaded sleeve 5 can be driven to move through the screw rod 3, so that the threaded sleeve 5 drives the turntable 7 to rotate. The rotation angle of the turntable 7 is consistent with the movement length of the threaded sleeve 5. Therefore, the rotation angle of the turntable 7 can be controlled by adjusting the movement stroke of the threaded sleeve 5 on the screw rod 3, thereby controlling the clamping range of the clamping block 12. It should be noted that when the rotation angle of the turntable 7 is large, the screw rod 3 and the base 14 should be connected through the rotating shaft to avoid the threaded sleeve 5 and the turntable 7 from getting stuck.

[0025] Reference Figure 2The exhaust assembly includes an exhaust pipe 15, the outer wall of the exhaust pipe 15 is slidably connected to the inside of the turntable 7, and the outer wall of the exhaust pipe 15 is slidably connected to the inside of the connecting box 1; the lower surface of the connecting box 1 is fixedly connected with a conical tube 19, and the lower surface of the conical tube 19 is fixedly connected with a conical tube 2 20; the outer wall of the conical tube 19 is fixedly connected with an intake pipe 17, and a fan 18 is arranged inside the intake pipe 17.

[0026] Specifically, a sealing ring should be provided at the connection between the air inlet pipe 17 and the exhaust hole of the device to ensure the sealing effect and avoid air leakage. When the fan 18 is working, the exhaust gas can be sucked into the conical tube 1 19. The volume of the conical tube 1 19 is smaller than that of the conical tube 2 20, and the conical tube 1 19 and the conical tube 2 20 are placed symmetrically. Therefore, the exhaust gas will be decelerated after entering the conical tube 2 20 to avoid stirring up the liquid in the adsorption box 21.

[0027] Reference Figure 4 The lower surface of the conical tube 20 is fixedly connected with an adsorption box 21; the outer wall of the adsorption box 21 is fixedly connected with an inlet pipe 22, and the outer wall of the adsorption box 21 is fixedly connected with an outlet pipe 23; the outer wall of the turntable 7 is rotatably connected to the inside of the connecting box 1, and the outer wall of the slide rod 10 is slidably connected to the inside of the connecting box 1; the outer wall of the exhaust pipe 15 is fixedly connected with an exhaust nozzle 16.

[0028] Specifically, the pollutants generated by the EB furnace usually include metal oxides, smoke and dust. In order to prevent environmental pollution, the exhaust gas needs to be treated. The liquid used to adsorb pollutants can be injected into the adsorption box 21 through the water inlet pipe 22. After the exhaust gas is passed into the liquid, not only the impurities contained therein can be adsorbed, but also the high-temperature exhaust gas can be cooled to reduce pollution to the environment.

[0029] Working principle: When it is necessary to use a pollutant purification device for an EB furnace, first connect the air inlet pipe 17 to the exhaust port of the device, start the fan 18, and the fan 18 sucks the exhaust gas into the conical tube 1 19, and then enters the conical tube 2 20 through the conical tube 19 and decelerates before passing into the adsorption box 21. Liquid for adsorbing exhaust gas is passed into the adsorption box 21 through the water inlet pipe 22. After the exhaust gas passes into the liquid, the impurities in the exhaust gas are adsorbed by the liquid. At this time, insert the exhaust pipe 15 into the connection box 1, turn the handle 2, and the handle 2 drives the screw 3 to rotate, and then the screw 3 is used to absorb the impurities in the exhaust gas. The threaded sleeve 5 is driven to move, and the movement of the threaded sleeve 5 drives the turntable 7 to rotate slightly, so that the turntable 7 drives the rotating shaft 2 8 to rotate, and then drives the sliding sleeve 9 to rotate through the rotating shaft 2 8. When the sliding sleeve 9 rotates, it drives the sliding rod 10, so that the clamping block 12 fits the outer wall of the exhaust pipe 15. At this time, the clamping block 12 rotates and adjusts the angle with the clamping block 12 under the action of the rotating shaft 3 11, so that the clamping is more stable. At this time, the gas overflowing from the liquid is discharged from the exhaust nozzle 16 through the exhaust pipe 15, and the liquid adsorbed with impurities is discharged from the water outlet pipe 23.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
