[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] A gas purification device that facilitates the removal of oily and fumes, such as Figures 1 to 6 As shown, the device includes a housing 1. A mounting ring 11 is welded to one outer wall of the housing 1, and an air suction hood 20 is welded to the inner circumference of the mounting ring 11. An air suction assembly is connected to one outer wall of the air suction hood 20. A card holder 12 is welded to one outer wall of the mounting ring 11, and a metal filter screen 2 is installed inside the card holder 12 by insertion. A slot 13 is opened on the side wall of the metal filter screen 2. A bracket 16 is welded to the outer circumference of the mounting ring 11, and a T-shaped rod 15 is slidably connected to a through hole on the surface of the bracket 16. One end of the T-shaped rod 15 is used in conjunction with the slot 13. A spring 14 is sleeved on the outer wall of the T-shaped rod 15, and the two ends of the spring 14 are respectively fixed to one outer wall of the bracket 16 and one inner wall of the T-shaped rod 15.

[0029] When it is necessary to purify the oil fumes, first insert the protrusion on the side of the metal filter screen 2 into the card holder 12, then align the side of the metal filter screen 2 with the mounting ring 11. Use the elastic force of the spring 14 to make the T-shaped rod 15 snap into the card slot 13, thereby limiting the position between the metal filter screen 2 and the mounting ring 11. Then, use the suction component to suck up the oil fumes. During the process of sucking up the oil fumes, the metal filter screen 2 first intercepts large oil droplets and solid impurities to reduce the subsequent processing load. At the same time, the metal filter screen 2 is set to be removable, so as to facilitate its regular cleaning.

[0030] The suction assembly includes a separation box 17 and a fixing plate 21. The fixing plate 21 is fixed to the inner wall of one side of the box 1 by bolts, and the separation box 17 is fixed to the side wall of the fixing plate 21 by bolts. The bottom of the separation box 17 and the suction hood 20 are connected by a suction pipe 19. A flue 9 is fixed to the top of the separation box 17. The suction assembly also includes a drive motor 10 and a turbine blade 23. The drive motor 10 is fixed to the top outer wall of the box 1 by bolts, and the top of the turbine blade 23 is connected to the output end of the drive motor 10 by a coupling.

[0031] When the drive motor 10 drives the turbine blades 23 to rotate, the turbine blades 23 generate negative pressure during rotation. Under the action of negative pressure, the oil fumes are sucked into the separation box 17 through the suction hood 20 and the suction pipe 19. After the oil fumes enter the separation box 17, the turbine blades 23 agitate the oil fumes, so that the oil fumes achieve separation between oil droplets and gas under the action of centrifugal force. The separated oil droplets slide down along the inner circumference of the separation box 17, while the gas is discharged from the top of the separation box 17 through the flue 9.

[0032] The bottom outer wall of the separation box 17 is fixed with a collection tray 25 by screws, and multiple sets of leakage holes 24 are opened at the bottom of the separation box 17. The bottom of the collection tray 25 is fixed with a connecting pipe 18 by a connector, and the end of the connecting pipe 18 away from the collection tray 25 is fixed with a collection cylinder 6 by a connector. The bottom of the collection cylinder 6 is fixed with a valve 5 by bolts.

[0033] After the oil droplets slide down the inner circumference of the separator 17, they eventually fall into the collection tray 25 through the drain hole 24. The part of the suction pipe 19 inside the separator 17 is higher than the bottom inner wall of the separator 17, thus preventing the oil droplets sliding down the inner circumference of the separator 17 from flowing back. The oil droplets that enter the collection tray 25 eventually enter the collection cylinder 6 through the connecting pipe 18. The collection cylinder 6 has a transparent structure, so the oil level in the collection cylinder 6 can be observed. When the oil level in the collection cylinder 6 is high, the valve 5 can be opened to drain the oil.

[0034] The top outer wall of the box 1 is fixed with a processing box 7 by screws, and the top of the processing box 7 is fitted with a cover plate 8 by fasteners. Limiting plates 30 are welded to both inner walls of the processing box 7, and filter plates 27 are slidably connected to the inner walls of the two limiting plates 30. The end of the flue 9 away from the separation box 17 is fixedly connected to the side wall of the processing box 7, and an exhaust pipe 22 is fixed to the other outer wall of the processing box 7.

[0035] The filter plate 27 can adsorb residual oil mist and other substances in the gas discharged through the flue 9. The filter plate 27 is preferably a HEPA filter.

[0036] The fastener includes a threaded post 28, an L-shaped plate 29, and a plug 31. The L-shaped plate 29 is welded to the outer wall of one side of the processing box 7, and the threaded post 28 is threaded to the inner wall of the threaded hole on the side of the L-shaped plate 29. The plug 31 is welded to one end of the threaded post 28. A connecting plate 26 is welded to the outer wall of one side of the cover plate 8, and the surface of the connecting plate 26 has a socket for use with the plug 31.

[0037] After the filter plate 27 and the limiting plate 30 are installed, the cover plate 8 is placed on top of the processing box 7. At this time, the socket and plug 31 on the connecting plate 26 are aligned with each other. Then, the threaded column 28 is rotated so that the plug 31 is inserted into the socket on the connecting plate 26, thereby limiting the distance between the cover plate 8 and the processing box 7.

[0038] An installation box 4 is welded to one side of the outer wall of the box 1, and a collection box 3 is placed inside the installation box 4;

[0039] The collection box 3 can collect large oil droplets and solid impurities intercepted by the metal filter 2. When cleaning is required, the collection box 3 can be removed from the installation box 4, which facilitates the subsequent recycling and cleaning of large oil droplets and solid impurities.

[0040] A controller 32 is installed on one outer wall of the housing 1;

[0041] The controller 32 can control the start, stop and operation of the drive motor 10, thereby driving the turbine blades 23 to rotate and generate negative pressure to achieve the absorption of oil fumes.

[0042] Working principle: The controller 32 starts the drive motor 10 to drive the turbine blades 23 to rotate and generate negative pressure. The oil fumes enter the separation box 17 through the suction hood 20 and the suction pipe 19. First, the large oil droplets and solid impurities are intercepted by the metal filter screen 2 and fall into the collection box 3. The oil droplets in the separation box 17 are stirred by the turbine blades 23 and slide down the inner wall of the separation box 17 due to centrifugal force, fall into the collection tray 25 through the leakage hole 24, and then enter the collection cylinder 6 through the connecting pipe 18. The gas enters the treatment box 7 through the flue 9 and is absorbed by the filter plate 27. The residual oil mist is then discharged from the discharge pipe 22. When the liquid level in the collection cylinder 6 is too high, the control valve 5 is opened to discharge the oil.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
