Description

Technical Field

[0001] The utility model relates to the technical field of oil mist recovery, in particular to an oil mist collector for machine tools. Background Art

[0002] During the process of machining and cutting parts by machine tools, due to the strong friction between metals, a large amount of heat will be generated. When the cutting fluid absorbs a large amount of heat, most of it will be recovered and utilized, but a part of it will evaporate into emulsions, oil mists and fumes. The oil mists and fumes will overflow outward when the equipment door is opened and closed, and quickly spread throughout the workshop, affecting the physical health of operators and also causing faults in the electrical system of the machine tool. Therefore, an oil mist collector is needed to purify the oil mist.

[0003] For example, the patent document with the publication number of CN212594778U discloses an oil mist collector for an oil mist recovery machine. By installing a filter mesh plate at the bottom of the fan assembly, when separating the oil mist, the fan assembly can convert electrical energy into mechanical energy. Through the high-speed rotation of the fan blades inside the fan assembly, local vacuum can be generated, so as to collect the oil mist. The oil throwing disc in the installation cover rotates under the influence of the suction of the fan assembly, and the oil in the oil mist can be thrown out by the rotation of the oil throwing disc, thus achieving the purpose of oil mist separation, avoiding the oil mist from entering the internal mechanical equipment of the fan assembly to damage the internal mechanical equipment, ensuring the safety of the fan assembly, and prolonging the service life of the device.

[0004] However, during the use of the above patent, because there are a large number of particles in the generated oil mist, the oil generated after being filtered by the filter mesh plate will contain particle agglomerates. If not filtered, it will cause the drain pipe to be blocked and affect the use. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an oil mist collector for machine tools to solve the above problems.

[0024] The present utility model will be further described below in conjunction with the drawings:

[0025] As Figures 1 - 5 shown, an oil mist collector for a machine tool includes a connecting plate 1. Two fixing plates 101 are welded to the top of the connecting plate 1. An oil removal mechanism for removing oil is installed between the two fixing plates 101. The oil removal mechanism includes a conversion box 201. A purification mechanism for adsorption is arranged on the front side of the conversion box 201. A filtering mechanism for removing particles in the oil is installed at the bottom of the conversion box 201. An oil outlet mechanism for discharging materials is arranged at the bottom of the filtering mechanism.

[0026] The conversion box 201 is bolted between two fixed plates 101. An installation plate 202 is bolted between the front and rear inner walls of the conversion box 201. A rotating shaft 203 is rotatably connected between the installation plate 202 and the top inner wall of the conversion box 201 through a bearing. A plurality of impellers 204 are key-connected to the rotating shaft 203. A motor 205 is bolted to the top of the conversion box 201. The output shaft of the motor 205 is connected to the top of the rotating shaft 203 through a coupling. An air inlet pipe 206 is welded to the rear side of the conversion box 201. By the operation of the motor 205, the rotating shaft 203 is driven to rotate, thereby driving the impellers 204 to rotate. Furthermore, by using the centrifugal force generated by the impellers 204, the oil mist is combined together and converted into a liquid state.

[0027] The purification mechanism includes a connecting pipe 301. The connecting pipe 301 is welded to the front side of the conversion box 201. A purification box 302 is welded to the front side of the connecting pipe 301. An adsorption plate 303 is bolted in the purification box 302. A fan 304 is bolted to the front side of the purification box 302. The liquefied oil mist will enter the purification box 302 through the connecting pipe 301. After being adsorbed by the adsorption plate 303, it is discharged from the device by the fan 304.

[0028] The filtering mechanism includes a feeding hopper 401. The feeding hopper 401 is welded to the bottom of the conversion box 201. A feeding pipe 402 is welded to the bottom of the feeding hopper 401. An installation frame 403 is slidably connected in the feeding pipe 402. A screen 404 is bolted to the bottom of the installation frame 403. The screen 404 is a rectangular filter net made of stainless steel. A handle 405 is bolted to the front side of the installation frame 403. The oil generated by liquefaction will fall into the feeding hopper 401 and then fall from the feeding hopper 401 into the feeding pipe 402. When the oil falls in the feeding pipe 402, it will first fall onto the screen 404 for screening. When it is necessary to clean the particle agglomerates on the surface of the screen 404, the installation frame 403 is pulled out by holding the handle 405, so that the screen 404 can be taken out, and then the particle agglomerates on the surface of the screen 404 can be cleaned. The oil outlet mechanism includes a storage tank 501. The storage tank 501 is welded to the bottom of the feeding pipe 402. A discharge block 502 is placed on the bottom inner wall of the storage tank 501. The discharge block 502 is a wedge-shaped block made of stainless steel. A box door 503 is installed on the rear side of the storage tank 501. A discharge pipe 504 is threadedly connected to the front side of the storage tank 501. A valve 505 is arranged in the discharge pipe 504. Then, after screening, it will continue to fall into the storage tank 501. Then the oil liquid will flow along the surface of the discharge block 502 into the discharge pipe 504 and finally flow out through the discharge pipe 504.

[0029] Working principle: When in use, open valve 505. Through the operation of blower 304, the oil mist is sucked from the intake pipe 206 into the conversion tank 201. At the same time, through the operation of motor 205, the rotating shaft 203 is driven to rotate, thereby driving the impeller 204 to rotate. Furthermore, by using the centrifugal force generated by the impeller 204, the oil mist is combined together and converted into a liquid state. Then the liquefied oil will fall into the hopper 401, and then fall from the hopper 401 into the discharge pipe 402. When the oil falls in the discharge pipe 402, it will first fall onto the screen 404, and then continue to fall into the storage tank 501 after screening. Then the oil liquid will flow along the surface of the discharge block 502 into the discharge pipe 504, and finally flow out through the discharge pipe 504. When it is necessary to clean the particle agglomerates on the surface of the screen 404, hold the handle 405 by hand and pull out the mounting frame 403, thereby taking out the screen 404, and then clean the particle agglomerates on the surface of the screen 404. Then the liquefied oil mist will enter the purification tank 302 through the connecting pipe 301, and after being adsorbed by the adsorption plate 303, it is discharged from the device by the blower 304.
