Description

Technical Field

[0001] The utility model relates to the technical field of oil mist separators, in particular to a multi-stage filtering oil mist separator. Background Art

[0002] In industrial production, such as when machine tools are processing workpieces, a large amount of oil mist will be generated. The oil mist contains a large number of particles. If it is discharged directly without treatment, it will not only affect the air, but also cause harm to the workers. Therefore, the oil mist needs to be treated. Only after the oil mist is treated can it be discharged normally.

[0003] The current method for treating oil mist is to use an oil mist separator to absorb the generated oil mist. The oil mist enters the oil mist separator and is separated by a separation device disposed inside to remove particles in the oil mist.

[0004] Although the above method can achieve the separation of oil mist, the common oil mist separators currently have only one-stage separation equipment, and most of them adsorb the particles in the oil mist through adsorption carbon. When the machine tool is working, a large amount of oil mist will be generated. At this time, the oil mist will be fully attached to the adsorption carbon. When the machine tool continues to be used for processing, the adsorption carbon will not be able to completely adsorb the oil mist, thereby affecting the separation effect of the oil mist. Therefore, we propose a multi-stage filtration oil mist separator to solve the above problem. Utility Model Content

[0026] Example

[0027] Reference Figure 1-Figure 4 The utility model provides a technical solution: a multi-stage filtering oil mist separator, including a bin body 1 and a multi-stage filtering mechanism 3, one side of the bin body 1 is fixedly connected to the air intake pipe 2, the multi-stage filtering mechanism 3 includes a first filter plate 31, the interior of the bin body 1 is fixedly connected to a vertical plate 311, the interior of the vertical plate 311 is equipped with the first filter plate 31, the interior of the bin body 1 is rotatably equipped with a mounting frame 321, one side of the mounting frame 321 is fixedly connected to a sponge block 32, a tail bin 331 is installed at one end of the bin body 1, and an activated carbon plate 33 is installed inside the tail bin 331.

[0028] In a preferred embodiment, a rectangular hole 4 is opened at the bottom end of the vertical plate 311, and the first filter plate 31 is fixedly installed inside the rectangular hole 4. An oil receiving pipe 5 is fixedly installed at the bottom of the bin body 1, and the oil receiving pipe 5 corresponds to the position of one side of the first filter plate 31. The device separates the oil mist by a graded treatment method, so the first filter plate 31 is fixedly installed inside the vertical plate 311, and the oil mist entering the bin body 1 can be processed by the first filter plate 31 to filter out larger particles in the oil mist.

[0029] In a preferred embodiment, the top of the warehouse body 1 is fixedly connected to the suction fan 6, the outlet end of the suction fan 6 is fixedly connected to the outlet pipe 7, one end of the outlet pipe 7 is fixedly installed inside the warehouse body 1, and the inlet pipe 8 is fixedly installed on the inlet end of the suction fan 6. In order to allow the oil mist generated by the machine tool to automatically enter the interior of the warehouse body 1, a suction fan 6 is installed on the top of the warehouse body 1. The suction fan 6 sucks external air and blows air into the interior of the warehouse body 1. The wind will pass quickly from one end of the air inlet pipe 2, so that a pressure difference is formed between the corresponding position of the air inlet pipe 2 inside the warehouse body 1 and the air pressure inside the air inlet pipe 2, so that the oil mist can be automatically sucked into the interior of the warehouse body 1, so as to separate and process the oil mist.

[0030] In a preferred embodiment, a drive motor 9 is fixedly installed on the top of the bin body 1, and the output end of the drive motor 9 is fixedly connected to the transmission shaft 10, and one end of the transmission shaft 10 is fixedly connected to the mounting bracket 321. The device also adopts a sponge block 32 treatment method. When the oil mist enters the position of the sponge block 32, it will directly adhere to the sponge block 32, thereby reducing the amount of oil mist to continue to move. In order to enable the oil mist to quickly adhere to the sponge block 32, the device drives the mounting bracket 321 to rotate by the drive motor 9, which can drive the sponge block 32 to rotate, thereby quickly attaching the oil mist to the sponge block 32.

[0031] The activated carbon plate 33 is installed in the tail bin 331 in the present device to facilitate the replacement of the activated carbon plate 33 so as to adsorb the oil mist. Therefore, in order to facilitate the disassembly and assembly of the tail bin 331, a limit plate 11 is provided on one side of the tail bin 331, and a through hole 12 is provided on the outer surface of the limit plate 11, and a threaded hole 13 is provided on the top of the bin body 1. The internal thread of the threaded hole 13 is connected to the screw 14, and the screw 14 is inserted into the inside of the through hole 12. The limit plate 11 is fixedly installed on one side of the tail bin 331, and the through hole 12 is provided on the limit plate 11, and the threaded hole 13 is provided on the bin body 1. The screw 14 is screwed into the inside of the threaded hole 13 and passes through the inside of the through hole 12, so that the limit plate 11 is installed on the bin body 1, thereby installing the tail bin 331 on the bin body 1. Conversely, by unscrewing the screw 14, the tail bin 331 can be removed, which is convenient for disassembly and assembly of the tail bin 331.

[0032] The sponge block 32 is attached with oil mist. Long-term attachment will make the internal gap of the sponge block 32 saturated, and the oil mist cannot be attached, which affects the use. In order to ensure that the sponge block 32 can normally attach the oil mist, an oil pressing mechanism 15 is installed inside the bin body 1. The oil pressing mechanism 15 includes a second filter plate 151 and a conical bin 152. The second filter plate 151 is fixedly installed inside the bin body 1. The sponge block 32 is set between the second filter plate 151 and the vertical plate 311, and slides with the outer surfaces of the second filter plate 151 and the vertical plate 311. A conical bin 152 is fixedly installed at the bottom of the bin body 1, and the interior of the conical bin 152 is communicated with the interior of the bin body 1. A control valve 16 is installed at the bottom of the conical bin 152. When the oil in the sponge block 32 is squeezed out, the sponge block 32 can be squeezed to the outer surface of the second filter plate 151 and the vertical plate 311 through the rotation of the sponge block 32, so as to squeeze the sponge block 32, squeeze out the oil in the sponge block 32, and discharge the oil in the sponge block 32, so that the oil mist can continue to adhere to the sponge block 32 to meet the use requirements.

[0033] Specifically, the working process or working principle of a multi-stage filtering oil mist separator is as follows: the current method of treating oil mist is to use an oil mist separator to absorb the generated oil mist, the oil mist enters the oil mist separator, and the oil mist is separated by the separation equipment arranged inside to remove the particles in the oil mist.

[0034] Although the above method can achieve the separation of oil mist, the common oil mist separators currently have only one-stage separation equipment, and most of them use adsorption carbon to adsorb particles in the oil mist. A large amount of oil mist will be generated when the machine tool is working. At this time, the oil mist will be fully attached to the adsorption carbon. When the machine tool is used for processing later, the adsorption carbon will not be able to completely adsorb the oil mist, thereby affecting the separation effect of the oil mist. Therefore, this device is designed to solve the problem. When in use, one end of the air intake pipe 2 of the device is installed inside the inner bin of the machine tool and connected to an external power supply. When the machine tool starts to process the workpiece, a certain amount of oil mist will be generated. At this time, the suction fan 6 is turned on, and the external air is drawn by the suction fan 6 and transported to the inside of the bin body 1. The air quickly passes through the other end of the air intake pipe 2 to form an air pressure difference. At this time, the air inside the machine tool will be sucked into the inside of the air intake pipe 2 and enter the inside of the bin body 1.

[0035] The suction fan 6 continuously absorbs external air and transports the air to the interior of the warehouse body 1. It also blows the oil mist sucked into the interior of the warehouse body 1 to the bottom of the interior of the warehouse body 1. Under the blowing of the air, the oil mist passes through the first filter plate 31, and the oil mist is processed by the first filter plate 31 to filter the larger particles in the oil mist. Then the oil mist enters the position of the sponge block 32.

[0036] By driving the mounting frame 321 to rotate through the driving motor 9, the sponge block 32 can be driven to rotate, and the oil mist entering the position of the sponge block 32 will adhere to the sponge block 32. When the sponge block 32 rotates, it will not only increase the flow of the oil mist inside the bin body 1, but also attach a large amount of oil mist to the sponge block 32. Then a small part of the oil mist will pass through the position of the second filter plate 151, and finally the oil mist will move to the position of the activated carbon plate 33, and the oil mist will be adsorbed by the activated carbon plate 33, and all the particles therein will be adsorbed on the activated carbon plate 33. The treated oil mist can be directly discharged into the atmosphere to avoid harm to the environment and staff.

[0037] After a large amount of oil mist adheres to the sponge block 32, its adhesion ability will become poor. In order to ensure that the sponge block 32 can always attach the oil mist to the sponge block 32, when the driving motor 9 drives the sponge block 32 to rotate, the sponge block 32 will be squeezed onto the second filter plate 151 and one side of the vertical plate 311. This process not only squeezes out the oil inside the sponge block 32, but also scrapes off the oil stains attached to the side of the second filter plate 151, so that the oil stains drip to the bottom of the bin body 1 and flow into the interior of the conical bin 152, so as to collect the oil stains. At the same time, the suction fan 6 continuously blows air to one side of the vertical plate 311, which can blow the oil stains attached to one side of the vertical plate 311 and drip it into the interior of the oil receiving pipe 5, so as to collect the oil stains so that they can be treated regularly.

[0038] This device uses an activated carbon plate 33 as the final treatment. After a period of use, the adsorption effect of the activated carbon plate 33 will be reduced, so the activated carbon plate 33 needs to be replaced regularly. By twisting the screw 14, the tail bin 331 is removed from the tail of the bin body 1, and the activated carbon plate 33 inside the tail bin 331 can be easily taken out, thereby replacing the activated carbon plate 33, so that the device can be used normally and the treatment effect on oil mist is guaranteed.

[0039] It should be noted that the suction fan 6 and the drive motor 9 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
