DETAILED DESCRIPTION

[0021] The present invention provides a dust screen cleaning device for a fume purifier. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to illustrate the present invention and are not intended to limit the present invention.

[0022] See also Figures 1 to 4 As shown, the utility model provides a dust screen cleaning device for an oil fume purifier, comprising a casing 1, a dust screen 2, a mounting groove 3 and a vibration device 4. An air inlet 11 is provided on one side of the casing 1, and two mounting grooves 3 arranged near the air inlet 11 are provided in the casing 1. The dust screen 2 is arranged between the two mounting grooves 3, and the dust screen 2 is inclined toward the air inlet 11. The vibration device 4 is arranged in the casing 1, and the vibration device 4 acts on the bottom of the dust screen 2 to cause the dust screen 2 to vibrate up and down.

[0023] like Figure 1 As shown, the housing 1 is provided with a purification unit 8, and a dust screen 2 is positioned between the purification unit 8 and the air inlet 11. Flue gas enters the housing 1 through the air inlet 11 and is initially filtered by the dust screen 2 before entering the purification unit 8 for purification. The dust screen 2 filters dust and other impurities from the flue gas. After a period of operation, the vibration device 4 is activated, causing the dust screen 2 to vibrate up and down within the two mounting slots 3 to shake off dust and other impurities attached to the dust screen 2. Since the dust screen 2 is tilted, the shaken impurities fall to the bottom of the housing 1 due to their own weight, thus achieving the function of automatically cleaning the dust screen 2. Compared to existing technologies, this can extend the cleaning cycle of the dust screen 2 when it is removed for cleaning.

[0024] In a preferred embodiment, see Figure 2 、 3 The vibrating device 4 is an air hammer, secured below the mounting slot 3 via a bracket 41 to ensure stable installation. The air hammer is connected to a compressed air supply, which enters the air hammer to drive the hammer head up and down. The mounting slot 3 below has a clearance hole 31 for the hammer head. The hammer head, through the clearance hole 31, acts on the bottom of the dust screen 2, causing the dust screen 2 to vibrate up and down, thereby shaking off dust adhering to its surface.

[0025] Preferably, when there is one air hammer, the air hammer is located at the lower middle part of the dust screen 2; when there are two air hammers, the two air hammers are symmetrically arranged to ensure that the entire dust screen 2 can vibrate up and down.

[0026] In a preferred embodiment, the dust screen 2 is tilted at an angle of 80° to 90°, which can ensure that the dust attached to the dust screen 2 falls to the bottom of the casing 1 due to vibration, and can also make the projected area of ​​the dust screen 2 on the vertical plane larger, thereby ensuring the efficiency of filtering smoke.

[0027] In a preferred embodiment, see Figure 2 、 3 The dust screen 2 includes a flow balancing net 21 and a grid 22 welded on the surface of the flow balancing net 21. The grid 22 is located on the side of the flow balancing net 21 close to the air inlet 11. The flow balancing net 21 is provided with a plurality of through holes arranged in a matrix. Through the above arrangement, the stability of the grid 22 fixed on the flow balancing net 21 can be improved, and the filtered smoke can be ensured to pass through the dust screen 2 smoothly.

[0028] In order to further improve the installation stability of the grid 22 , pressure strips 23 are welded around the grid 22 . One side of the pressure strip 23 is fixed to the flow equalizing network 21 , and the other side covers the grid 22 .

[0029] In practical applications, in order to ensure the filtering effect of the dust screen 2, the mesh size of the grid 22 should be determined according to actual working conditions.

[0030] Furthermore, L-shaped flanges 211 are provided around the flow balancing net 21, and the L-shaped flanges 211 are located on the side of the flow balancing net 21 away from the air inlet 11. Through the above-mentioned setting, the structural strength of the flow balancing net 21 is improved, thereby extending the service life of the dust screening net 2.

[0031] In a preferred embodiment, see Figure 2 The cross-section of the mounting groove 3 is a U-shaped structure. The two mounting grooves 3 are arranged opposite to each other. The dust screen 2 is arranged between the two mounting grooves 3. To prevent the dust screen 2 from detaching from the two mounting grooves 3 during the up and down vibration process, the distance between the bottoms of the two mounting grooves 3 is greater than the height of the dust screen 2, and the distance between the sides of the two mounting grooves 3 is less than the height of the dust screen 2.

[0032] In a preferred embodiment, see Figure 4 A cabinet door 5 is hinged on one side of the casing 1, and the cabinet door 5 is arranged perpendicular to the installation groove 3, that is, one end of the installation groove 3 abuts against the side of the casing 1 away from the cabinet door 5, and the other side abuts against the cabinet door 5. Therefore, when the dust screen 2 needs to be deeply cleaned or replaced, the cabinet door 5 is opened, and then the dust screen 2 is pulled outward along the installation groove 3 to remove the dust screen 2. The operation is simple and convenient.

[0033] In order to improve the sealing between the dust screen 2 and the inner wall of the casing 1 and ensure that all smoke passes through the dust screen 2, a sealing plate 6 is provided between each mounting groove 3 and the inner wall of the casing 1 it is adjacent to.

[0034] Further, see Figure 4 A rib 7 is provided between the two mounting grooves 3. The rib 7 is provided close to the side of the casing 1 away from the cabinet door 5. The distance between the rib 7 and the cabinet door 5 is the width of the dust screen 2. Through the above arrangement, during operation, the rib 7 and the cabinet door 5 limit the left and right movement of the dust screen 2, so that the dust screen 2 only vibrates up and down; when installing and removing the dust screen 2, the dust screen 2 can be pulled out or pushed in along the direction of the mounting groove 3, and the operation is simple.

[0035] In summary, the present invention sets a dust screen 2 between the air inlet 11 and the purification unit 8 of the oil fume purifier, and the dust screen 2 is set at an angle. When the air hammer located below the dust screen 2 acts on the bottom of the dust screen 2, the dust screen 2 vibrates up and down in the two mounting grooves 3, thereby shaking off the dust and other impurities attached to its surface. The shaken-off dust falls directly to the bottom of the casing 1, so as to realize the function of automatically cleaning the dust screen 2, and can extend the cleaning cycle of removing the dust screen 2 for cleaning. In addition, a sealing plate 6 is provided between each mounting groove 3 and the inner wall of the casing 1, and a retaining edge 7 cooperates with the cabinet door 5 to limit the left and right movement of the dust screen 2, so as to ensure that the dust screen 2 only vibrates up and down between the two mounting grooves 3, and all the smoke is filtered through the dust screen 2 before flowing to the purification unit 8 at the rear.

[0036] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the claims attached to the present invention.
