Technical Field

[0001] The present invention relates to the technical field of oil mist separation and treatment, and specifically to an oil mist separation and treatment device, a control method, and a storage medium. Background Art

[0002] During the production process in a CNC machining workshop, a large amount of oil mist waste gas is usually generated. These waste gases pose a potential threat to the health of operators, so it is necessary to effectively purify them.

[0003] Currently, for oil mist separation, mainly the following three types of equipment are used for oil mist separation and purification treatment, namely mechanical filtration type oil mist separation equipment, electrostatic oil mist purification equipment, and centrifugal oil mist separation equipment.

[0004] For an electrostatic purification device, when the dust collecting electrode reaches the adsorption saturation state, its purification efficiency will drop sharply, making it difficult to meet the requirements of outdoor emission standards. The mechanical filtration type equipment and the electrostatic oil mist purification device have the same technical problem, that is, the filter medium is prone to blockage, resulting in the system air volume being unable to maintain the design requirements, thereby affecting the purification effect. Summary of the Invention

[0014] Through the above technical solution, automatic cleaning of the exhaust holes can be achieved, ensuring the flux of the exhaust holes, and at the same time, cleaning of the inner wall of the barrel can be realized. It solves the problem that the mechanical filtration equipment and electrostatic oil mist purification devices in the prior art are prone to blockage, resulting in the inability to maintain the designed air volume of the system, thereby affecting the purification effect.

[0020] In some embodiments, the exhaust direction of the exhaust hole is obliquely upward.

[0021] In some embodiments, the first driving part includes:

[0022] A toothed disc, which is provided with a plurality of arc-shaped grooves diverging outward from the central area of the toothed disc;

[0023] A telescopic arm, one end of which is provided with a guide block, and the other end is fixedly connected to the arc-shaped scraper; the guide block is embedded in the arc-shaped groove and can slide along the track of the arc-shaped groove; when the guide block slides back and forth along the track of the arc-shaped groove, the telescopic arm moves back and forth in the radial direction of the barrel body;

[0024] A driving assembly, which is used to drive the toothed disc to rotate.

[0025] In some embodiments, the arc-shaped groove includes a starting end and an ending end; the starting end is the end close to the center of the toothed disc; the ending end is the end far from the center of the toothed disc;

[0026] When the guide block is located at the ending end of the arc-shaped groove, the arc-shaped scraper abuts against the inner wall of the barrel; when the guide block is located at the starting end of the arc-shaped groove, the cleaning part can extend into the exhaust hole.

[0027] In some embodiments, the oil mist separation treatment device further includes a spraying mechanism;

On the other hand, it can realize the cleaning of the separation hollow roller and the inner wall of the barrel.

[0040] Further, the nozzle of the spraying mechanism sprays downward from the upper part inside the barrel, so that the water mist sprayed by the nozzle generates convection with the gas discharged from the exhaust hole to form a turbulent flow.

[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] The first aspect of the present invention provides an oil mist separation and treatment device, as Figures 1 - 7 shown, the oil mist separation and treatment device includes a barrel body 10, a separation empty roller 20, a first driving assembly, and a cleaning mechanism.

[0059] The barrel body 10 includes a barrel wall and a chamber defined by the barrel wall and having an exhaust port 11 and a liquid discharge port 12. The exhaust port 11 is provided at the top of the barrel body 10, and a valve is provided at the exhaust port 11 for opening or closing the exhaust port 11. Preferably, the valve is an electromagnetic valve.

[0060] The separation empty rollers 20 are distributed along the axial direction of the barrel body 10 and are rotatably installed in the chamber. The bottom end of the separation empty roller 20 is connected with an air inlet pipe 21 extending outside the chamber, and a plurality of exhaust holes 22 are provided on the side wall, and a plurality of swirl plates are provided on the inner wall. The swirl plates play a role in impinging the oil mist mixed gas and intercepting and capturing the oil mist.

[0061] The separation empty roller 20 rotates due to the drive of the first drive assembly. The air inlet end of the air inlet pipe 10 is located outside the barrel body 10, and the air outlet end extends into the barrel body 10 and communicates with the separation empty roller 20.

[0062] At least one end of the separation empty roller 20 is rotatably connected to the barrel body 10. It can be that the separation empty roller 20 itself is rotatably connected to the barrel body 10 through a bearing, or the air inlet pipe 21 connecting the separation empty roller 20 is rotatably connected to the barrel body 10 through a bearing. If the air inlet pipe 21 is rotatably connected to the barrel body 10, there are certain requirements for the diameter of the air inlet pipe 21, that is, the air inlet pipe 21 cannot be too thin, and the air inlet pipe 21 is a rigid pipe, such as a stainless steel pipe, otherwise it is difficult to support the entire separation empty roller 20 and it is also difficult to support the rotation of the entire separation empty roller 20. For the setting of the diameter of the air inlet pipe 21, it can be determined according to actual needs. Those skilled in the art are capable of selecting an air inlet pipe 21 with a suitable diameter according to the actual operation requirements. In the present invention, the air inlet pipe 21 is rotatably connected to the barrel body 10 through a bearing or a rotary joint.

[0063] It needs to be further explained that if the air inlet pipe 21 is rotatably connected to the barrel body 10, since the barrel body 10 does not rotate and the air inlet pipe 21 rotates, the external connecting pipe of the air inlet pipe 21 needs to be rotatably connected to the air inlet pipe 21. This rotational connection can also be achieved through a bearing or a rotary joint. The rotary joint realizes the relative rotation of the air inlet pipe 21 and the external connecting pipe through precision bearings and a sealing assembly, and can maintain the fluid or gas passage at the same time.

[0064] In an optional specific embodiment, the first drive assembly includes a first drive motor, a first toothed belt, a first pulley and a second pulley. The first pulley is installed at the output end of the first drive motor, and the second pulley is fixedly sleeved on the air inlet pipe 21 located outside the barrel body 10. The second pulley can be connected to the air inlet pipe 21 by a key connection. The first toothed belt is sleeved on the first pulley and the second pulley at the same time.

[0065] The waste gas containing oil mist first enters the separation hollow roller 20, where the first oil mist treatment process is carried out. Specifically, the waste gas containing oil mist is introduced into the separation hollow roller 20 through the intake pipe 21. The first driving assembly drives the centrifugal hollow roller 20 to rotate. Based on the setting of the swirl plate, the oil mist droplets in the waste gas are captured due to hitting the swirl plate, and then flow out or are thrown out of the exhaust holes 22. At the same time, based on the setting of the swirl plate, the large oil mist droplets are broken up into small oil mist droplets by the swirl plate. Part of the oil mist that fails to be treated or the small oil mist droplets are discharged from the separation hollow roller 20 together with the gas, enter the chamber in the barrel body 10, and enter the second oil mist treatment process.

[0066] The second treatment process is realized by the spraying mechanism. Specifically, the spraying mechanism includes an annular water supply pipe 61, a spray head 62, and a water supply pipe 63. The annular water supply pipe 61 is located above the top of the barrel body 10 and is distributed along the contour of the barrel body 10. The spray head 62 is connected to the annular water supply pipe 61 and extends into the barrel body 10. Of course, the annular water supply pipe 61 can also be directly arranged on the inner top of the barrel body 10. One end of the water supply pipe 63 is connected to the annular water supply pipe 61, and the other end is connected to the water storage tank 64. The water in the water storage tank 64 is pumped out by a water pump.

[0067] The water storage tank can be installed on the barrel body 10 or can be set separately from the barrel body 10. It should be noted that if the water storage tank 64 is installed on the barrel body 10, the water storage tank 64 is installed on the side wall of the barrel body 10 near the top or directly installed on the top of the barrel body 10. This can reduce the lift of the water pump.

[0068] The spraying liquid is sprayed downward from the upper part of the barrel body 10 to capture the oil mist in the waste gas. The generated oil-water mixture deposits at the bottom of the barrel body 10 and is discharged through the liquid discharge port 12. Therefore, in the present invention, the liquid discharge port 12 is arranged on the side wall of the barrel body 10 near the bottom or on the outer bottom wall of the barrel body 10. A valve is arranged at the liquid discharge port 12 for opening or closing the liquid discharge port 12. Preferably, the valve here is an electromagnetic valve.

[0069] In an optional specific implementation manner, the exhaust holes 22 are uniformly distributed on the circumferential side wall of the separation hollow roller 20. Such a setting can prevent the waste gas discharged from the separation hollow roller 20 from gathering in a certain local area of the barrel body 10. The gathering of the waste gas is not conducive to the treatment of the oil mist in the spraying process and reduces the efficiency of spraying and separating the oil mist. Further, a plurality of holes can be arranged on the bottom wall of the separation hollow roller 20 to facilitate the discharge of the liquid oil stain.

[0070] In order to further improve the efficiency of spray separation of oil mist, the exhaust holes 22 are arranged obliquely upward, that is, the axis of the exhaust holes 22 is not perpendicular to the axis of the separation hollow roller 20. Preferably, the included angle between the axis of the exhaust holes 22 and the axis of the separation hollow roller 20 is set to 30°-60°. Arranging the exhaust direction of the exhaust holes 22 obliquely upward can make the gas flow direction from the exhaust holes 22 form a convection with the water mist ejected by the spray head 62, thus forming a turbulent flow and improving the separation effect.

[0071] After the oil mist accumulates, it will form viscous oil stains. Therefore, long-term operation may cause some of the exhaust holes 22 to be blocked and the oil stains to be deposited on the side wall of the barrel 10. To maintain the flux of the exhaust holes 22 and the cleanliness of the side wall of the barrel 10, a cleaning mechanism is provided.

[0072] As Figure 2 and Figure 5 shown, the cleaning mechanism includes an arc-shaped scraper 30, a cleaning part and a first driving part. The arc-shaped scraper 30 has the same curvature as the inner wall of the barrel. The cleaning part is arranged on the arc-shaped scraper 30 and faces the separation hollow roller 20. The first driving part is used to drive the arc-shaped scraper 30 to move towards or away from the exhaust holes 22 so that the cleaning part can dredge the exhaust holes 22, and is used to drive the arc-shaped scraper 30 to rotate against the inner wall of the barrel 10.

[0073] As Figure 3 and Figure 5 shown, the first driving part includes a toothed disc 51, a telescopic arm 53 and a driving component. The toothed disc 51 is provided with a plurality of arc-shaped grooves 52 diverging outward from the central area of the toothed disc 51. One end of the telescopic arm 53 is provided with a guide block 54, and the other end is fixedly connected to the arc-shaped scraper 30. The guide block 54 is embedded in the arc-shaped groove 52 and can slide along the track of the arc-shaped groove 52. When the guide block 54 slides back and forth along the track of the arc-shaped groove 52, the telescopic arm 53 moves back and forth along the radial direction of the barrel 10. The driving component is used to drive the toothed disc 51 to rotate, so as to drive the guide block 54 to move in the arc-shaped groove 52, so that the telescopic arm 53 can move along the radial direction of the toothed disc 51.

[0074] In an optional specific embodiment, the driving component includes a second driving motor 55a arranged on the outer top of the barrel 10. The output shaft of the second driving motor 55a is rotatably connected to the barrel 10 and extends into the barrel 10 and is key-connected to the center of the toothed disc 51. The output shaft of the second driving motor 55a can be rotatably connected to the barrel 10 through a bearing.

[0075] It should be noted that the length of the telescopic arm 53 itself does not change, that is, the radial movement of the telescopic arm 53 is not achieved by changing its own length, but by the movement of the guide block 54 in the arc-shaped groove 52.

[0076] The arc-shaped groove 52 includes a starting end and an ending end. The starting end is the end close to the center of the gear disk 51. The ending end is the end far from the center of the gear disk 51. When the guide block 54 is located at the ending end of the arc-shaped groove 52, the arc-shaped scraping plate 30 abuts against the inner wall of the barrel body 10. When the driving assembly further drives the gear disk 51 to rotate, the arc-shaped scraping plate 30 will rotate while abutting against the inner wall of the barrel body 10 to scrape off the oil stains adhering to the inner wall of the barrel body 10. When the guide block 54 is located at the starting end of the arc-shaped groove 52, the cleaning part can extend into the exhaust hole 22 to clean the oil stains blocked in the exhaust hole 22.

[0077] The length of the arc-shaped groove 52 in the radial direction is the maximum radial movement stroke of the telescopic arm 53. Therefore, the arc-shaped groove 52 has two functions. One is to provide structural support for the radial movement of the telescopic arm 53, and the other is to limit the radial movement range of the telescopic arm 53.

[0078] The cleaning part specifically includes a base 41, a dredging rod 42 and bristles 43. The base 61 is installed on the arc-shaped scraping plate 30. One end of the dredging rod 42 is connected to the base 41. The bristles 43 are arranged at the other end of the dredging rod 42. The width of the arc-shaped scraping plate 30 is set as narrow as possible. The reason is that if the width of the arc-shaped scraping plate 30 is relatively wide, when scraping the oil stains on the inner wall of the barrel body 10, the oil stains will adhere to the arc-shaped scraping plate 30 and become a new oil stain aggregation area. The width of the arc-shaped scraping plate 30 only needs to be sufficient to install the base 41.

[0079] The diameter of the dredging rod 62 is set to be slightly smaller than the diameter of the exhaust hole 22, and the diameter of the cylinder formed by the bristles 43 is set to be slightly larger than the diameter of the exhaust hole 22. The reason for such a setting is that since the bristles 43 are flexible, when pushing the bristles 43 into the separation empty roller 2, the outer bristles 43 cannot enter the exhaust hole 22 at first, and only the part of the bristles 43 corresponding to the diameter of the exhaust hole 22 enters the exhaust hole 22. When further pushing the bristles 43 towards the exhaust hole 22, the remaining part of the bristles 43 will enter the exhaust hole 22.

[0080] As can be seen from the previous discussion, when pushing the bristles 43 into the separation empty roller 2, the outer bristles 43 cannot enter the exhaust hole 22 at first, and the outer bristles 43 lie on the outer wall of the separation empty roller 2, so that the effect of cleaning the oil stains on the outer wall of the separation empty roller 2 can actually be achieved.

[0081] In an optional specific embodiment, the base 41 is replaced by a motor, the output shaft of which is connected to the dredging rod 42, and is used to drive the dredging rod 42 to rotate. When the bristles 43 extend into the exhaust hole 22, the dredging rod 42 can be driven by the motor to rotate, thereby driving the bristles 43 to rotate. The flexible bristles 43 are opened due to the centrifugal force, expanding the cleaning area within the centrifugal empty roller 20. The dredging rod 42 can be made of a material with a certain hardness and a certain deformation ability, such as a rubber material.

[0082] In an optional specific embodiment of the present invention, a stepper motor is selected as the first driving motor for driving the separation empty roller 20. The reason is that if the exhaust hole 22 is to be cleaned by the cleaning part, the dredging rod 42 needs to be aligned with the exhaust hole 22. The stepper motor has high precision, and the exhaust hole 22 and the dredging rod 42 can be aligned with the window opened on the barrel body 10.

[0083] The advantage of using a clearing rod 42 made of a rubber material with a certain hardness and a certain deformation ability is that if there is a slight deviation between the clearing rod 42 and the exhaust hole 22, based on the certain deformation ability of the clearing rod 42, it can still extend into the exhaust hole 22 with the bristles 43.

[0084] In general, the drive assembly is used to drive the toothed disc 51 to rotate, including forward and reverse rotation. Specifically, the drive assembly drives the toothed disc 51 to drive the telescopic arm 53 to move back and forth in the radial direction, so that the bristles 43 can extend into or out of the exhaust hole 22 to clean the exhaust hole 22. When the guide block 54 moves to the end of the arc groove 52, the arc scraper 30 is against the inner wall of the barrel body 10. At this time, the radial movement stroke of the telescopic arm 53 has reached the limit. When the toothed disc 51 is further driven to rotate, the arc scraper 30 will move along the trajectory of the inner wall of the barrel body 10 to scrape off the oil stains on the inner wall of the barrel body 10.

[0085] A second aspect of the present invention provides a control method for an oil mist separation treatment device, the control method comprising:

[0086] Oil mist separation steps

[0087] The waste gas is passed into the separation empty roller 20, and the separation empty roller 20 is driven to rotate, and the oil mist in the waste gas is separated for the first time based on the centrifugal force; the gas after the first separation is dispersed and discharged; the gas is subjected to a second separation treatment through the spray mechanism;

[0088] Separation empty roller 20 cleaning steps

[0089] The toothed disc 51 is repeatedly driven to rotate forward and reverse, so that the dredging rod is extended into and out of the exhaust hole 22 to clean the liquid viscous oil accumulated in the exhaust hole 22;

[0090] Inner wall cleaning steps of the barrel body 10

[0091] Drive the tooth disc 51 to rotate so that the guide block 54 is located at the end of the arc-shaped groove 52, making the arc-shaped scraper 30 abut against the inner wall of the barrel body 10; further drive the tooth disc 51 to rotate so that the arc-shaped scraper 30 moves along the inner wall track of the barrel to scrape off the liquid viscous oil stains attached to the inner wall of the barrel body 10.

[0092] Furthermore, the nozzles of the spraying mechanism spray downward from the upper part inside the barrel body 10 so that the water mist sprayed by the nozzles generates convection with the gas discharged from the exhaust hole 22 to form a turbulent flow.

[0093] The third aspect of the present invention provides a computer-readable storage medium, on which a computer program is stored. It is characterized in that when the computer program is executed on a computer, the computer is made to execute the control method described above.

[0094] The above has described the embodiments of the invention in detail, but the content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
