Description

Technical Field

[0001] This utility model relates to the field of centrifugal purification mesh trays, specifically an oil fume purification mesh tray. Background Technology

[0002] A fume purification mesh is a device that uses a high-speed rotating mesh to trap most of the oil mist and discharge it outwards under centrifugal force.

[0003] In existing technologies, a fixed oil collection hood is usually set on the outer periphery of the mesh disk so that the splashed oil enters the oil collection hood. However, the oil tends to adhere to the inner wall of the oil collection hood, making it difficult to clean over time. Utility Model Content

[0004] The purpose of this utility model is to provide an oil fume purification mesh tray in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil fume purification mesh disc, comprising two mesh discs arranged one in front of the other, with the blades of the two mesh discs staggered in the circumferential direction. An oil collection mechanism is provided on the outer periphery of each mesh disc, and a scraper inserted into the oil collection mechanism is installed on the outer periphery of each mesh disc. The end of the oil collection mechanism is integrally formed with a downwardly protruding oil outlet, the inner cavity of which is connected to the inner cavity of the oil collection mechanism, and the bottom end of the oil outlet has an open structure.

[0006] As a further embodiment of this utility model: the oil collection mechanism includes an oil collection cover disposed on the outer periphery of the mesh disk, the inner circumference of the oil collection cover is integrally formed with two No. 1 connecting rings and two No. 2 connecting rings, an annular groove is formed between one No. 1 connecting ring and one No. 2 connecting ring, and the oil outlet is connected to the inner cavity of the annular groove.

[0007] As a further improvement of this utility model: the blades of the mesh disk are provided with oil collecting grooves distributed along their extension trajectory, and the end of the oil collecting groove near the oil collecting cover has an open structure.

[0008] As a further improvement of this utility model: the vertical cross-section of the first connecting ring is in the shape of an "L" and the edge of the annular part of the first connecting ring does not block the opening of the oil collection groove.

[0009] As a further improvement of this invention, the scraper extends into the inner cavity of the annular groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting up an oil collection mechanism and a scraper, the scraper scrapes the oil that enters the annular groove as it rotates at high speed with the mesh disc, and discharges it out through the oil outlet, thus avoiding the problem of oil accumulating in the annular groove and making it difficult to clean.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment of the utility model, an oil fume purification mesh disc includes two mesh discs 1, which are distributed one in front of the other and the blades of the two mesh discs 1 are staggered in the circumferential direction. An oil collection mechanism is provided on the outer periphery of the mesh disc 1, and a scraper 4 inserted into the oil collection mechanism is installed on the outer periphery of the mesh disc 1. The end of the oil collection mechanism is integrally formed with a downward protruding oil outlet 3, the inner cavity of the oil outlet 3 is connected to the inner cavity of the oil collection mechanism, and the bottom end of the oil outlet 3 is open.

[0019] In this embodiment: when using the device to exhaust cooking fumes, the drive mechanism (such as a motor belt drive mechanism) connected to it is activated. Since the two mesh discs 1 are coaxially connected at their centers, the drive mechanism can drive the two mesh discs 1 to rotate simultaneously when running. The rotating mesh discs 1 generate suction, which draws in the cooking fumes. During the process of the fumes being drawn in, the oil mist contained in the fumes will come into contact with the blades of the mesh discs 1. The oil mist that comes into contact with the mesh discs 1 is thrown into the oil collection mechanism under centrifugal force. The oil that enters the oil collection mechanism is scraped downwards by the rotating scraper 4 and discharged outwards from the oil outlet 3, preventing oil from accumulating in the oil collection mechanism.

[0020] Please refer to this carefully. Figure 2 and Figure 3 The oil collection mechanism includes an oil collection cover 2 disposed on the outer periphery of the mesh disk 1. The inner periphery of the oil collection cover 2 is integrally formed with two first connecting rings 5 ​​and two second connecting rings 6. An annular groove 7 is formed between one first connecting ring 5 and one second connecting ring 6. The oil discharge port 3 is connected to the inner cavity of the annular groove 7.

[0021] In this embodiment: during the high-speed rotation of the mesh disk 1, the oil mist intercepted by the blades of the mesh disk 1 enters the annular groove 7 under centrifugal force, and then flows along the inner wall of the annular groove 7 under the scraping of the scraper 4, and is discharged through the oil outlet 3, thus avoiding the accumulation of oil in the annular groove 7.

[0022] Please refer to this carefully. Figure 3 and Figure 4 Oil collecting grooves 8 are provided on the blades of the mesh disk 1 along its extension trajectory. The end of the oil collecting groove 8 near the oil collecting cover 2 is open. The vertical section of the first connecting ring 5 is "L" shaped. The edge of the annular part of the first connecting ring 5 does not block the opening of the oil collecting groove 8.

[0023] In this embodiment: after the oil mist is intercepted by the blades of the mesh disk 1, under centrifugal force, the oil mist flows along the oil collection groove 8 and enters the annular groove 7 through the opening of the oil collection groove 8.

[0024] Please refer to this carefully. Figure 2 The scraper 4 extends into the inner cavity of the annular groove 7.

[0025] In this embodiment: as the scraper 4 rotates with the mesh disk 1, it scrapes the oil that has entered the inner wall of the annular groove 7 and discharges the oil outward as it passes through the oil outlet 3.

[0026] 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.
