[0002] In the metal heat treatment industry, quenching is one of the most important processes. The purpose of quenching parts is to significantly improve the strength, hardness, and wear resistance of steel, thereby meeting the different usage requirements of various mechanical parts and tools. During the quenching process, a large amount of exhaust gas containing oil fumes and dust is generated. In open quenching equipment, a large amount of oil fume exhaust gas is emitted into the workshop at the moment of quenching, which not only pollutes the workshop environment but also seriously endangers the health of employees.

[0003] In the process of treating oil fume, an oil fume treatment device is needed to treat the oil fume. When the oil fume treatment device is used for a long time, the filter screen is easily clogged with oil. However, the existing oil fume treatment device cannot clean the filter screen, which leads to the clogging of the mesh, affects the normal operation of the oil fume treatment device, and reduces the practicality of the oil fume treatment device.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] This utility model provides a quenching furnace with oil fume treatment function for processing. By setting up an air pump to generate suction, the oil fumes generated at the top of the quenching furnace are transported to the inside of the oil fume treatment box through the air pipe. The fumes are filtered by a first filter screen and then filtered again by a second filter screen. The oil stains adhere to the screens and are softened by a cleaning liquid. The gas is purified in the liquid.

[0018] This utility model provides a quenching furnace with oil fume treatment function for processing. By setting a motor to drive the drive rod to make the cam rotate at a constant speed, the cam's convex end can push the moving horizontal plate to move upward.

The moving horizontal plate moves upward and drives the connecting rod to cause the brake vertical plate to move the cleaning plate and brush upward. When the convex end of the cam rotates away, the moving horizontal plate loses the driving force and rebounds to its original position under the elastic counter-pushing force of the return spring. Thus, the brake vertical plate moves the cleaning plate and brush downward, thereby realizing up and down reciprocating motion. The brush moves up and down to facilitate cleaning of the mesh, prevents mesh blockage, and improves the efficiency of use.

[0019] This utility model provides a quenching furnace with oil fume treatment function for processing. By setting a brake vertical plate to drive the cleaning plate to move up and down reciprocally, it can promote the fluidity of the cleaning liquid, further increase the contact area between the gas and the cleaning liquid, thereby improving the purification effect.

[0027] like Figure 1-5 As shown, this utility model provides a quenching furnace with oil fume treatment function for processing, including a quenching device body 1, a quenching furnace 2, an oil fume treatment box 3 arranged on the rear side of the quenching furnace 2, and support legs 4 fixedly installed on the bottom perimeter of both the quenching furnace 2 and the oil fume treatment box 3. A filter unit is arranged inside the oil fume treatment box 3, and cleaning units are arranged on both sides of the filter unit. The filter unit includes a filter screen 34 detachably installed inside the left side of the oil fume treatment box 3, and a filter screen 35 detachably installed inside the right side of the oil fume treatment box 3. The top rear side of the quenching furnace 2... An air intake box 21 is fixedly installed on the top. An air pump 22 is fixedly installed on the rear outer surface of the quenching furnace 2. An air extraction pipe 23 is fixedly installed on the input end of the air pump 22. The other end of the air extraction pipe 23 is fixedly installed inside the rear side of the air intake box 21. An air guide pipe 24 is fixedly installed on the output end of the air pump 22. The other end of the air guide pipe 24 is fixedly installed inside the front side of the fume treatment box 3. Liquid inlets 31 are fixedly connected to both sides of the top of the fume treatment box 3. An exhaust port 32 is fixedly installed on the top right side of the fume treatment box 3. An outlet 33 is fixedly installed on the bottom right side of the fume treatment box 3.

[0028] Furthermore, the cleaning liquid is introduced into the interior of the fume treatment box 3 through the liquid inlet 31. Then, the suction pump 22 is started to generate suction, which, together with the suction pipe 23, transports the oil fumes generated at the top of the quenching furnace 2 to the interior of the fume treatment box 3 through the air guide pipe 24. The oil fumes enter the interior of the fume treatment box 3 and are filtered by the first filter screen 34, and then filtered again by the second filter screen 35. The oil stains adhere to the screens and are softened by the cleaning liquid. The gas is purified in the liquid and is then discharged to the outside through the exhaust port 32. Example

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the cleaning unit includes brake vertical plates 36 movably inserted into both sides of the top of the fume treatment box 3. A cleaning plate 37 is fixedly connected to the bottom end of the brake vertical plates 36. A brush 38 is fixedly installed on the inner wall of the cleaning plate 37. The brush is attached to the outer surface of the filter screen 34 and the filter screen 35. A motor 39 is fixedly installed on the rear side of the fume treatment box 3. A drive rod 31 is fixedly installed on the output end of the motor 39. 0. A cam 311 is fixedly sleeved on the outer surface of the drive rod 310. Limiting slide rods 312 are fixedly installed on both sides of the rear top of the fume treatment box 3. A moving horizontal plate 313 is slidably sleeved on the outer surface of the limiting slide rod 312. A return spring 314 is movably sleeved on the outer surface of the limiting slide rod 312 above the moving horizontal plate 313. Connecting rods 315 are fixedly installed on the inner sides of both ends of the moving horizontal plate 313. The other end of the connecting rod 315 is fixedly installed on the rear top of the brake vertical plate 36.

[0030] Furthermore, during the filtration process, the motor 39 drives the drive rod 310 to cause the cam 311 to rotate at a constant speed. When the cam 311 rotates, its protruding end can push the moving horizontal plate 313 upward. At this time, the return spring 314 is in a contracted state. The upward movement of the moving horizontal plate 313 drives the connecting rod 315 to cause the brake vertical plate 36 to drive the cleaning plate 37 and the brush 38 to move upward as well. When the protruding end of the cam 311 rotates and moves away, the moving horizontal plate 313 loses its driving force and rebounds to its original position under the elastic counter-pushing force of the return spring 314. Thus, the brake vertical plate 36 drives the cleaning plate 37 and the brush 38 to move downward as well, thereby realizing the up-and-down reciprocating motion. The up-and-down reciprocating motion of the brush 38 facilitates the cleaning of the screen and prevents the screen holes from clogging. When the brake vertical plate 36 drives the cleaning plate 37 to move up and down as well, it can promote the flow of the cleaning liquid, further increase the contact area between the gas and the cleaning liquid, and thus improve the purification purpose.

[0031] The working principle of this quenching furnace with oil fume treatment function will be explained in detail below.

[0032] like Figure 1-5As shown, during use, the cleaning liquid is first introduced into the oil fume treatment box 3 through the inlet 31. Then, the suction pump 22 is started to generate suction, which, together with the suction pipe 23, transports the oil fumes generated at the top of the quenching furnace 2 to the oil fume treatment box 3 through the air guide pipe 24. The oil fumes enter the oil fume treatment box 3 and are filtered by the first filter screen 34, and then filtered again by the second filter screen 35. The oil stains adhere to the screens and are softened by the cleaning liquid. The gas is purified in the liquid, and the exhaust port 32 facilitates the discharge to the outside. During the filtration process, the motor 39 drives the drive rod 310 to make the cam 311 rotate at a constant speed. When the cam 311 rotates, its convex end can push As the moving horizontal plate 313 moves upward, the return spring 314 is in a contracted state. The upward movement of the moving horizontal plate 313 drives the connecting rod 315 to cause the braking vertical plate 36 to move the cleaning plate 37 and the brush 38 upward. When the protruding end of the cam 311 rotates and moves away, the moving horizontal plate 313 loses its driving force and rebounds to its original position under the elastic counter-driving force of the return spring 314. Thus, the braking vertical plate 36 drives the cleaning plate 37 and the brush 38 to move downward, thereby realizing the up-and-down reciprocating motion. The up-and-down reciprocating motion of the brush 38 facilitates the cleaning of the mesh and prevents the mesh from becoming clogged. When the braking vertical plate 36 drives the cleaning plate 37 to move up and down, it can promote the flow of the cleaning fluid, further increase the contact area between the gas and the cleaning fluid, and thus improve the purification purpose.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
