Description

Technical Field

[0001] The present application relates to the field of environmental protection equipment, and in particular to an environmental protection treatment device for quenching oil smoke. Background Art

[0002] Quenching is an important process in heat treatment production and a key process to improve the comprehensive performance of workpieces. There are many kinds of quenching media, and quenching oil is still the most widely used. During the quenching process, when the hot workpiece is immersed in the quenching oil, the quenching oil will burn violently and produce a large amount of oil smoke. After the workpiece completely enters the quenching oil, the combustion stops, but oil smoke still escapes from the surface of the quenching oil. These oil fumes have a strong irritating smell and contain a large amount of carcinogens such as benzopyrene. Long-term inhalation will cause great harm to the health of employees. At the same time, because the oil fume has a strong adsorption capacity, long-term quenching operation will cause a layer of oil sludge to adhere to the walls, roofs, and equipment surfaces of the factory, which seriously affects the workshop environment and poses a major safety hazard.

[0003] A quenching fume environmental treatment device (publication number: CN212310376U) disclosed on the Chinese patent website has solved the problem that the traditional workshop quenching fume is in an unorganized emission state, and the workshop is mostly filled with smoke. A small number of companies use leaf spring quenching fume environmental treatment equipment to treat the fume exhaust gas. The collection hoods in its collection system are all multi-opening and fully open, resulting in incomplete collection of fume exhaust gas, which is scattered everywhere without treatment and has low fume collection efficiency. However, the following problems still exist:

[0004] During the collection process, the oil fume is not completely discharged outward along the collecting air duct. Due to the easy adhesion of oil fume, some oil stains are easily adhered to the collecting air duct and the inner wall of the pipe on its surface. When there is airflow in the collecting air duct to collect the oil fume, the oil stains are blown by the wind, but when the collecting air duct stops, the oil stains gradually gather and drip downward under the action of gravity, and then easily drip directly onto the surface of the quenching station, resulting in more oil stains on the surface of the quenching station, which not only affects the appearance of the quenching station surface, but also affects the use of the quenching station surface equipment. Utility Model Content

[0005] In order to solve the technical problem that the quenching station is inconvenient to use due to dripping oil, the present application provides a quenching oil fume environmental protection treatment device.

An exhaust fan is installed at one end of the collecting air duct to further suck the fume in the collecting air duct.

[0008] Optionally, the collecting device includes a collecting cover, which is funnel-shaped, an inner side wall of the collecting cover is fixedly connected to a fixing rod, a terminal surface of the fixing rod is hinged to a collecting plate, and a surface of the collecting plate is trapezoidal.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0020] A quenching fume environmental protection treatment device comprises a quenching station 1 for quenching and a collecting air duct 2 for collecting the fume generated by quenching. A collecting device 3 is installed on the lower end surface of the collecting air duct 2. When in use, the lower end of the collecting device 3 covers the surface of the quenching station 1, and the collecting air duct 2 extracts the fume on the surface of the quenching station 1 through the collecting device 3. By installing an exhaust fan at one end of the collecting air duct 2, the fume in the collecting air duct 2 is sucked.

[0021] The collecting device 3 includes a collecting hood 31, which is funnel-shaped. A fixing rod 32 is fixedly connected to the inner wall of the collecting hood 31. A collecting plate 33 is hinged on the end surface of the fixing rod 32. The surface of the collecting plate 33 is trapezoidal. The collecting plate 33 is movably installed on the inner wall surface of the collecting hood 31 through the fixing rod 32, so as to facilitate changing the contact state between the upper end of the collecting plate 33 and the upper end of the inner wall of the collecting hood 31.

[0022] A guide rod 34 is hinged on the side wall surface of the lower end of the collecting plate 33, and the surface of the guide rod 34 is T-shaped. A mounting rod 35 is fixedly connected to the inner top wall of the collecting air duct 2. A limiting groove 36 is provided on the side wall surface of the lower end of the mounting rod 35. The end of the guide rod 34 is located inside the limiting groove 36, and the end surface of the guide rod 34 is slidably connected to the inner wall of the limiting groove 36. The inner top wall and the inner bottom wall of the limiting groove 36 are used to drive the end of the guide rod 34, so as to facilitate pushing the lower end of the collecting plate 33 through the guide rod 34. A sleeve 37 is threadedly connected to the lower surface of the mounting rod 35, and a collecting box 38 is fixedly connected to the lower surface of the sleeve 37. The collecting box 38 is located below the collecting plate 33, and the oil dripping from the lower end of the collecting plate 33 is collected by using the mobile phone box, so as to prevent the oil from entering the quenching station 1, thereby avoiding affecting the use of the quenching station 1.

[0023] By installing the collecting device 3 on the surface of the collecting air duct 2, the collecting hood 31 in the collecting device 3 is used to suck the oil smoke on the surface of the quenching station 1 through the collecting air duct 2, and the collecting plate 33 is movably installed on the inner side of the collecting hood 31, and the deflection of the collecting plate 33 is controlled by the mounting rod 35 and the guide rod 34, so that it is convenient to deflect the collecting plate 33 according to the working state of the collecting hood 31, so that when the collecting hood 31 and the collecting air duct 2 are working, the collecting plate 33 stands upright to avoid obstructing the ventilation in the collecting hood 31, and when the collecting hood 31 covers the quenching station 1, the upper end of the collecting plate 33 contacts the inner wall of the collecting hood 31, and then the oil smoke adhered to the inner wall of the collecting hood 31 and the collecting air duct 2 is collected, thereby avoiding the characteristic of dripping oil when the quenching oil smoke environmental protection treatment device is used.

[0024] A connecting hose 4 is fixedly connected to the upper surface of the collecting hood 31, and the mounting rod 35 is located on the inner side of the connecting hose 4. The upper end of the connecting hose 4 is fixedly connected and communicated with the lower end of the collecting air duct 2. A fixing frame 5 is fixedly connected to the edge of the lower surface of the collecting hood 31. A limiting rod 6 is fixedly connected to the edge of the upper surface of the quenching station 1. The side wall surface of the limiting rod 6 is slidably connected to the outer surface of the fixing frame 5. The limiting rod 6 is used to limit the operation of the collecting hood 31 through the fixing frame 5, so as to prevent the collecting hood 31 from deviating from the surface of the quenching station 1. A push rod 7 is fixedly connected to the upper surface of the fixing frame 5. The upper surfaces of the two adjacent push rods 7 are fixedly connected to connecting rods 8. A cylinder 9 is installed on the upper surface of the connecting rod 8. The cylinder 9 is used to drive the collecting hood 31 to rise and fall through the push rod 7, so as to provide power for the lifting of the collecting hood 31.

[0025] Working principle:

[0026] When in use, the cylinder 9 is started, and the cylinder 9 drives the collection cover 31 to rise through the connecting rod 8 and the push rod 7. The lower end of the push rod 7 drives the collection cover 31 to rise, and the mounting rod 35 is stationary. The collection cover 31 drives the guide rod 34 to slide in the limit groove 36 through the collection plate 33, and under the action of the top wall in the limit groove 36, the guide rod 34 tends to be horizontal, and the guide rod 34 pushes the lower end of the collection plate 33 outward, and the collection plate 33 stands upright, and the collection air duct 2 is started. The collection air duct 2 is sucked through the connecting hose 4 and the collection cover 31, and the oil smoke enters the collection air duct 2 through the collection cover 31 and the connecting hose 4;

[0027] After use, close the collecting air duct 2 and start the cylinder 9. The cylinder 9 drives the collecting hood 31 to descend through the connecting rod 8 and the push rod 7. The lower end of the push rod 7 drives the collecting hood 31 to descend, and the mounting rod 35 is stationary. The collecting hood 31 drives the guide rod 34 to slide in the limiting groove 36 through the collecting plate 33, and under the action of the inner bottom wall of the limiting groove 36, the guide rod 34 pulls the lower end of the collecting plate 33 close to the surface of the mounting rod 35, and the upper end of the collecting plate 33 is tightly attached to the inner bottom wall of the upper end of the collecting hood 31. The lower end of the collecting plate 33 is located above the collecting box 38. The oil and dirt in the collecting air duct 2 and the connecting pipe drip downward through the collecting plate 33 and enter the collecting box 38.
