Description

Technical Field

[0001] This utility model relates to the field of oil fume treatment technology, and in particular to an oil fume and oil mist treatment device. Background Technology

[0002] In industrial production, processes such as crystal cutting and grinding generate large amounts of oil fumes and mist. Existing oil fume and mist treatment systems typically include an air inlet pipe, a pretreatment device (filter), a treatment chamber, and an exhaust pipe. The air inlet pipe and the pretreatment device are connected via a plug-in connection. During actual operation, due to the high pressure upstream of the filter, oil spillage easily occurs at the connection point between the pretreatment device and the air inlet pipe. This oil spillage not only pollutes the surrounding environment and increases cleaning and maintenance costs, but also reduces the effectiveness and efficiency of oil fume and mist treatment. Utility Model Content

[0003] The purpose of this invention is to provide an oil fume and oil mist treatment device that, by setting a labyrinth-type sealing structure, can effectively prevent oil spillage from the upper part of the pretreatment device.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An oil fume and oil mist treatment device includes an air inlet pipe, a treatment box, and an exhaust pipe. The air inlet pipe is equipped with a pretreatment device, and the treatment box is equipped with an electrostatic adsorption mechanism, an activated carbon filtration mechanism, and a fan. The air inlet pipe includes an upper section and a lower section. A flange is formed at the bottom of the upper section, and multiple coaxially arranged annular grooves are formed on the flange.

[0006] The pretreatment device includes a housing and a filter assembly disposed within the housing. The upper part of the housing has multiple coaxially arranged convex rings, which are inserted into annular grooves, forming a labyrinth-like structure. The lower part of the housing is inserted into the lower half. Under the action of the fan, oil fumes and mist enter the intake pipe, where they undergo preliminary filtration by the pretreatment device before entering the treatment chamber. After passing through multiple treatments via electrostatic adsorption and activated carbon adsorption mechanisms, they are discharged from the exhaust pipe. The labyrinth-like structure between the housing and the upper half increases the path and difficulty of oil spillage, effectively preventing oil spillage.

[0007] Furthermore, the height of the multiple convex rings increases sequentially from the inside to the outside, which further increases the difficulty of oil spillage and thus further reduces the possibility of oil spillage.

[0008] Furthermore, the flange and the upper part of the housing are connected by a clamp.

[0009] Furthermore, a first bevel is formed on the flange;

[0010] The upper part of the shell is formed with a second inclined surface;

[0011] The clamp has a V-shaped cross-section, and its inner wall is attached to the first and second inclined surfaces.

[0012] The clamps can effectively secure the flange and the housing, improving the connection stability between them, preventing the intake pipe and the pretreatment device from detaching, and also improving the sealing performance between them, reducing the risk of oil spillage.

[0013] Furthermore, the filter assembly includes a filter screen and retaining rings fixed at both ends of the filter screen, with the retaining rings inserted into the housing;

[0014] The retaining ring on the lower side abuts against the collecting ring located on its lower side, and the collecting ring is fixed to the oil collecting tank; the oil collecting tank is fixed inside the shell;

[0015] The collecting ring is formed with tapered holes that are larger at the top and smaller at the bottom. Oil fumes and mist enter the filter screen, where most of the oil is trapped inside. A small portion of small oil particles pass through the filter screen and enter the processing tank. The oil trapped inside the filter screen automatically flows downwards and through the collecting ring into the oil collection tank for storage. Regular cleaning of the oil can extend the filter screen's lifespan.

[0016] Furthermore, the bottom of the oil collection tank is connected to an oil outlet pipe, and a valve is connected to the protruding end of the oil outlet pipe that extends outside the shell. Opening the valve allows the oil sludge in the oil collection tank to be discharged through the oil outlet pipe, eliminating the need for disassembly and assembly of the pretreatment device.

[0017] The outstanding effect of this utility model is:

[0018] Compared with existing technologies, by setting a labyrinth-shaped structure between the housing and the upper half of the intake pipe, the path and difficulty of oil spillage are increased, and oil spillage can be effectively prevented even when the pressure at the upstream end of the filter screen is high.

[0019] The oil outlet pipe and valve connected to the bottom of the oil collection tank eliminate the need to disassemble the pretreatment device when cleaning up oil sludge. Simply open the valve to discharge the oil sludge, making operation simple and improving the convenience and efficiency of equipment maintenance. Attached Figure Description

The upper part of the housing 41 has multiple coaxially arranged protruding rings 43, which are inserted into annular grooves 14, forming a labyrinth-like structure. The lower part of the housing 41 is inserted into a lower section 12, which is connected to the air inlet of the treatment chamber. The exhaust pipe is connected to the air outlet of the treatment chamber. Under the action of the fan, oil fumes and mist enter the air inlet pipe, where they undergo preliminary filtration by the pretreatment device before entering the treatment chamber. After multiple treatments by an electrostatic adsorption mechanism and an activated carbon adsorption mechanism, they are discharged from the exhaust pipe. The labyrinth-like structure between the housing and the upper section increases the path and difficulty of oil spillage, effectively preventing oil spillage.

[0032] The height of the multiple convex rings 43 increases sequentially from the inside to the outside, which can further increase the difficulty of oil spillage and thus further reduce the possibility of oil spillage.

[0033] The flange 13 and the upper part of the housing 41 are connected by a clamp 5.

[0036] The clamp 5 has a "V" shaped cross section, and the inner wall of the clamp 5 is attached to the first inclined surface 15 and the second inclined surface 44.

[0037] The clamps can effectively secure the flange and the housing, improving the connection stability between them, preventing the intake pipe and the pretreatment device from detaching, and also improving the sealing performance between them, reducing the risk of oil spillage.

[0038] like Figure 2 , Figure 3 As shown, the filter assembly 42 includes a filter screen 421 and retaining rings 422 fixed at both ends of the filter screen 421. The retaining rings 422 are inserted into the housing 41.

[0039] The retaining ring 422 on the lower side abuts against the collecting ring 45 located on its lower side, and the collecting ring 45 is fixed to the oil collecting tank 46; the oil collecting tank 46 is fixed inside the housing 41;

[0040] The collecting ring 45 is formed with tapered holes that are larger at the top and smaller at the bottom. Oil fumes and mist enter the filter screen, where most of the oil is trapped inside. A small portion of small oil particles pass through the filter screen and enter the processing tank. The oil trapped inside the filter screen automatically flows downwards and enters the oil collection tank through the collecting ring for storage. Regular cleaning of the oil can extend the filter screen's lifespan.

[0041] The bottom of the oil collection tank 46 is connected to an oil outlet pipe 47, and the protruding end of the oil outlet pipe 47 extending outside the housing 41 is connected to a valve 48. Opening the valve allows the oil sludge in the oil collection tank to be discharged through the oil outlet pipe, eliminating the need for disassembly and assembly of the pretreatment device.
