[0002] In the field of mechanical manufacturing, lubricants, coolants and cleaning fluids used in mechanical processing will be atomized, and the atomized oil mist is prone to fission, which poses a serious hazard to personnel. For example, when the lubricating cooling oil is heated to a certain temperature, it will fission into toxic and harmful substances such as acrolein, benzopyrene and cyclic aromatic hydrocarbons. It also has a strong odor and will directly cause mutagenic, teratogenic and even carcinogenic effects on production personnel.

[0003] During machining, iron will produce small particles during the cutting process, which will float away with the oil mist. The existing oil mist exhaust gas treatment equipment will absorb this part of the iron particles when treating the oil mist, and it is impossible to filter and collect them, causing the iron particles to seriously clog the purification mechanism, requiring personnel to frequently clean the purification mechanism. Summary of the invention

Moreover, the collecting tube can be easily disassembled from the V-shaped tube, and the electromagnet will not adsorb the iron particles after the power is turned off. Therefore, the collected iron particles are easy for personnel to take away from the collecting tube. The device can easily collect the iron particles in the oil mist, thereby preventing the iron particles from clogging the purification mechanism, so that personnel do not need to frequently clean the purification mechanism.

[0017] 2. By setting floating foam and rotating plates, when the nozzle sprays liquid to purify oil, the liquid will fall into the inside of the tower body, and when the liquid surface contacts the floating foam, the floating foam will be subject to buoyancy, so that with the cooperation of the bearing and the rotating shaft, the rotating plate will tilt toward the impurity discharge pipe. When the liquid carries impurities in the oil mist and falls on the top of the rotating plate, the impurities will flow to the impurity discharge pipe under the action of gravity, making it convenient for personnel to discharge the impurities inside the tower body through the impurity discharge pipe.

[0027] The air intake module comprises an air intake pipe, an air intake scoop and an air intake fan, and one end of the air intake pipe is connected to the iron particle collection module.

[0028] Wherein, the preliminary purification module is an electrostatic precipitator.

[0029] The iron particle collection module further comprises an air supply pipe, and an air supply fan is arranged inside the air supply pipe, and the air supply pipe is connected with the V-shaped pipe.

[0030] An oil mist exhaust gas treatment device comprises a V-shaped pipe 10, an electrostatic precipitator 8 and a tower body 1, wherein a discharge pipe 14 connected to the V-shaped pipe 10 is welded at the bottom low point thereof, and the outer periphery of the discharge pipe 14 is connected to a collecting cylinder 13 having an internal thread through a reserved thread, an electromagnet 18 is installed in the collecting cylinder 13 through a mounting frame, one end of the V-shaped pipe 10 is connected to the air inlet of the electrostatic precipitator 8 through a flange, and the air outlet pipe of the electrostatic precipitator 8 is connected to the tower body 1 through an air delivery pipe 7, an annular pipe 19 is installed at the top of the tower body 1 through screws, and a nozzle 20 is installed at the bottom of the annular pipe 19 through a reserved threaded hole

[0031] In this embodiment, Figure 1 , 2 As shown in FIG. 3 , the oil mist in the V-shaped tube 10 can contact the electromagnet 18, so that the electromagnet 18 can adsorb the iron particles contained in the oil mist. Moreover, the iron particles will fall faster than the oil mist due to their own heavy weight, thereby ensuring the collection efficiency and quality of the iron particles.

[0032] Among them, a bearing 24 is installed at the bottom of the tower body 1 through a reserved groove, and a rotating shaft 21 is connected to the rotating circle of the bearing 24, a rotating plate 23 is installed at one end of the rotating shaft 21 through screws, and a floating foam 22 is glued to the bottom of one end of the rotating plate 23, an exhaust pipe 5 is installed on the top of the tower body 1 through bolts, and a drainage pipe 4 connected to the tower body 1 is welded at the bottom of one side of the tower body 1, and a valve 3 is provided on the drainage pipe 4, a water pump 2 is installed at one end of the tower body 1 through screws, and the water outlet end at the top of the water pump 2 is connected to the annular pipe 19 through a pipeline.

[0033] In this embodiment, Figure 1 , 3 As shown, when the liquid surface in the tower body 1 contacts the floating foam 22, the floating foam 22 will be subjected to buoyancy, so that with the cooperation of the bearing 24 and the rotating shaft 21, the rotating plate 23 will tilt toward the impurity discharge pipe 4. When the impurities in the oil mist carried by the liquid fall on the top of the rotating plate 23, the impurities will flow to the impurity discharge pipe 4 under the action of gravity, thereby facilitating personnel to discharge the impurities inside the tower body 1 through the impurity discharge pipe 4.

[0034] The other end of the V-shaped tube 10 is welded with an air intake pipe 9, and the end of the air intake pipe 9 is welded with an air intake scoop 15, and an air intake fan 16 is installed in the air intake scoop 15 by screws.

[0040] When the present invention is working, the personnel connect the electrical appliance of the device to the external power supply equipment, and then connect the water pump 2 to the external liquid supply pipeline. In the next step, the personnel can turn on the air intake fan 16, the electrostatic precipitator 8, the electromagnet 18 and the air supply fan 17. The air intake fan 16 can transport the scattered oil mist into the V-shaped tube 10. At this time, the air supply fan 17 will blow gas into the V-shaped tube 10, so that the oil mist can fully contact the electromagnet 18, so that the electromagnet 18 can adsorb the iron particles contained in the oil mist, and the iron particles will fall faster than the oil mist due to their own heavy weight, thereby ensuring the collection efficiency and quality of the iron particles. In the next step, when the oil mist enters the electrostatic precipitator 8, the electrostatic precipitator 8 can adsorb the iron particles contained in the oil mist. Some dust is collected and transported to the inside of the tower body 1, and the water pump 2 can spray the corresponding liquid through the nozzle 20, so that the liquid is fully in contact with the oil mist, and then the oil mist is purified. After the oil mist is purified, it can be discharged from the tower body 1 through the exhaust pipe 5. In this process, the liquid sprayed by the nozzle 20 will fall into the inside of the tower body 1. When the liquid surface contacts the floating foam 22, the floating foam 22 will be subject to buoyancy, so that under the cooperation of the bearing 24 and the rotating shaft 21, the rotating plate 23 is tilted toward the impurity discharge pipe 4, so that when the liquid carries the impurities in the oil mist and falls on the top of the rotating plate 23, the impurities will flow to the impurity discharge pipe 4 under the action of gravity, so that it is convenient for personnel to discharge the impurities inside the tower body 1 through the impurity discharge pipe 4.
