DETAILED DESCRIPTION

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] This embodiment provides an oil mist removal air purification device, referring to Figure 1 and Figure 2 As shown, it includes a housing 100 and an oil mist filter assembly 200. The housing 100 is provided with an air inlet 101, an exhaust port, and a gas channel 102 located between the air inlet 101 and the exhaust port. Along the direction from the air inlet 101 to the exhaust port, the oil mist filter assembly 200 includes a plant fiber filter mesh, a plurality of metal sponge layers 220, and a plasma generator 230 sequentially arranged in the gas channel 102; and along the direction from the air inlet 101 to the exhaust port, the density of each metal sponge layer 220 increases sequentially.

[0020] Based on the above-mentioned overall structure, when the oil mist removal air purification device of this embodiment is in use, the air containing oil mist can be introduced into the box body 100 from the air inlet 101 of the box body 100, and after being filtered and purified by the oil mist filter assembly 200 in the gas channel 102, it can be discharged from the exhaust port on the box body 100.

[0021] The oil mist filter assembly 200 purifies the air containing oil mist as follows: first, the air containing oil mist passes through the plant fiber filter. When passing through the plant fiber filter 210, larger oil mist particles can be directly intercepted by the plant fiber filter, and smaller particles can be absorbed by the plant fiber. At the same time, after absorbing the oil mist, the plant fiber can swell and reduce the pores, which can further enhance the interception of fine particles of oil mist. It should be noted that the plant fiber filter 210 can adopt an existing product, which will not be described in detail here.

[0022] Secondly, the pore size of the filter holes of the sponge metal layer is smaller than the diameter of the filter holes of the plant fiber filter screen, so the smaller particles of oil mist that are not filtered out by the plant fiber filter screen 210 can be filtered out by the sponge metal layer. Moreover, the pore size of the filter holes on the sponge metal layer is inversely correlated with the density of the sponge metal, that is, the greater the density of the sponge metal, the smaller the pore size of the filter holes on the sponge metal. Therefore, in this embodiment, by providing several layers of sponge metal layers with different densities, oil mist of different particle sizes can be filtered out in turn, thereby achieving a better filtering effect on the oil mist. It should be noted that the sponge metal material can also use existing products, which will not be described in detail here.

[0023] Finally, by setting up a plasma generator 230, high voltage discharge is used to electrolyze charged ions, and the charged ions undergo oxidation-reduction reactions with oil smoke and organic matter, which can remove the oil mist that is not filtered out by the plant fiber filter layer and the metal sponge layer 220, thereby further completing the gas purification. It should be noted that the plasma generator 230 can also use existing products, which will not be described in detail here.

[0024] In general, the oil mist particles in the air can be filtered out in sequence by the plant fiber filter, the metal sponge layers 220 and the plasma generator 230, so that the oil mist particles in the air can be filtered out better overall.

[0025] For specific structure, refer to Figure 1 As shown, in this embodiment, a quadrangular pyramid-shaped end cover 300 is fixedly provided on one end of the housing 100, and a circular ring 310 coaxial with the end cover 300 is fixedly provided on the tip of the end cover 300; the air inlet 101 includes an inner hole of the circular ring 310 and a through hole constructed on the end cover 300. By setting the above structure, oil mist can enter the housing 100 from the air inlet 101.

[0026] refer to Figure 1 and Figure 2 As shown, relative to the end provided with the end cover 300, the other end of the box body 100 is provided with a circular cover body 400 which is connected with the exhaust port of the box body 100, and a draft fan is provided in the cover body 400, and the draft fan is used to form the movement of gas from the air inlet 101 to the exhaust port; and the cover body 400 is provided with an exhaust port 401 facing upward. That is, in this embodiment, through the rotation of the draft fan, the air can be forced to flow from the air inlet 101 of the box body 100 to the exhaust port of the box body 100, and discharged from the exhaust port 401 on the cover body 400.

[0027] In this embodiment, the box body 100 is provided with a first smoke sensor located at the air inlet 101 and a second smoke sensor located at the exhaust port. In this embodiment, by providing the first smoke sensor and the second smoke sensor, the purification effect of the oil mist removal air purification device can be judged according to the detection results of the first smoke sensor and the second smoke sensor, so as to take corresponding measures, for example, when the treatment effect does not meet expectations, the oil mist filter assembly 200 is replaced or the speed of the induced draft fan described below is reduced. It should be noted that the first smoke sensor and the second smoke sensor can adopt existing products, which will not be described in detail here. Since it does not affect the understanding, the first smoke sensor and the second smoke sensor are not shown in the drawings of this embodiment.

[0028] In this embodiment, an ozone concentration sensor located at the exhaust port is also provided on the box 100. Since the plasma generator 230 generates ozone, the ozone concentration sensor is provided to monitor the ozone concentration in the gas discharged from the degreasing mist air purification device, and when the ozone concentration in the discharged gas is higher than a preset concentration threshold, corresponding processing can be performed. It should be noted that the ozone concentration sensor can adopt an existing product, which will not be described in detail here. Since it does not affect understanding, the ozone concentration sensor is not shown in the drawings of this embodiment.

[0029] In this embodiment, reference Figure 3As shown, corresponding to each metal sponge layer 220, a socket 103 is provided on the box body 100, and each metal sponge layer 220 is respectively provided in a drawable manner in the corresponding socket 103. That is, in this embodiment, each metal sponge layer 220 can be inserted into the corresponding socket 103 to filter the air containing oil mist, and each metal sponge layer 220 can also be drawn out from the corresponding socket 103 to clean or replace the sponge metal layer.

[0030] refer to Figure 3 and Figure 4 As shown, the metal sponge layer 220 of this embodiment includes an outer frame and an inner frame; the outer frame includes a hard first frame body 221, and a soft connector 222 disposed on the inner wall of the first frame body 221, and the soft connector 222 is corrugated; the inner frame includes a second frame body 223 connected to the inner wall of the connector 222, and a metal sponge body 224 disposed on the inner wall of the second frame body 223. Specifically, the metal sponge body 224 filters and absorbs oil mist particles.

[0031] In this embodiment, by setting the metal sponge layer 220 of the above structure, the inner frame can have a displacement relative to the outer frame through the extension or retraction of the soft connecting piece 222. When the inner frame vibrates under the drive of the below-mentioned excitation device 500, the oil mist particles adsorbed on the metal sponge body 224 can fall off the metal sponge body 224 through the vibration of the inner frame, thereby extending the single use time of each metal sponge layer 220.

[0032] refer to Figure 3 As shown, in this embodiment, push rods 225 are fixed on both sides of the second frame 223; a first long hole 201 is opened on the first frame 221, and the length direction of the first long hole 201 is parallel to the height direction of the box 100, and the push rod 225 can pass through the first long hole 201. A vibration device 500 is provided on the box 100, and the vibration device 500 can be connected with the push rod 225 and can drive the push rod 225 to slide along the height direction of the box 100. That is, in this embodiment, the vibration of the second frame 223 is formed by driving the push rod 225 to slide back and forth along the height direction of the box 100 by the vibration device 500.

[0033] For specific structure, refer to Figure 3As shown, the vibration excitation device 500 of this embodiment includes two guide rods 510 fixedly mounted on the box body 100. The two guide rods 510 are parallel and spaced apart, and the axial directions of the two guide rods 510 are parallel to the height direction of the box body 100. A slide seat 520 is slidably mounted on the two guide rods 510, and elastic members 530 are respectively abutted on the upper and lower sides of the slide seat 520. A motor 540 is fixedly mounted on the slide seat 520, and an eccentric wheel 550 is fixedly sleeved on the motor shaft of the motor 540; and a connecting block 560 is detachably mounted on the slide seat 520, and the connecting block 560 is detachably fixedly connected to the thrust rod 225.

[0034] In this embodiment, after the connecting block 560 is fixed on the slide 520 and the motor 540 is started, the motor 540 drives the eccentric wheel 550 to rotate. The rotation of the eccentric wheel 550 will cause the slide 520 to be subjected to an unbalanced centrifugal force, so that the slide 520 can slide back and forth along the axial direction of the guide rod 510, thereby driving the thrust rod 225 to move back and forth up and down, causing the metal sponge 224 to vibrate along the height direction of the box body 100.

[0035] In this embodiment, the width of the first elongated hole 201 is greater than the diameter of the thrust rod 225, so that the thrust rod 225 can move in the first elongated hole 201 along the width direction of the first elongated hole 201, that is, the sponge metal body can have a displacement relative to the box body 100 along the length direction of the box body 100. In addition to being able to vibrate up and down, the metal sponge body 224 can also vibrate along the length direction of the box body 100.

[0036] refer to Figure 5 As shown, in this embodiment, a second elongated hole 501 is constructed on the above-mentioned connecting block 560, and the length direction of the second elongated hole 501 is inclined relative to the height direction of the box body 100, and a plurality of rollers 561 are rotatably provided on two side walls of the second elongated hole 501 parallel to its length direction. An elongated insertion end 226 is provided at the end of the thrust rod 225, and the insertion end 226 extends into the second elongated hole 501 and abuts against the outer peripheral surfaces of the rollers 561 on both sides.

[0037] In this embodiment, by providing the above-mentioned second elongated hole 501 and insertion end 226, when the slide 520 vibrates up and down due to the rotation of the eccentric block, because the second elongated hole 501 is arranged obliquely, the position change of the insertion end 226 in the second elongated hole 501 will cause the insertion end 226, that is, the sponge metal body, to have displacement along the length direction of the box body 100. Therefore, by making the second elongated hole 501 move up and down frequently with the slide 520, the metal sponge body 224 can be made to vibrate along the length direction of the box body 100. Overall, in this embodiment, by providing the above-mentioned excitation mechanism, the metal sponge body 224 can be made to vibrate along the height direction of the box body 100 and along the length direction of the box body 100.

[0038] In the embodiment, two through holes are provided on the slide 520, and two through holes are provided on the connection block 560 that are opposite to the two through holes, so that bolts pass through the through holes and the opposite through holes and are screwed with nuts to form a connection between the slide 520 and the connection block 560. That is, in the embodiment, the connection between the connection block 560 and the slide 520 can be formed by a bolt pair, so that the connection block 560 and the slide 520 can be connected or separated.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
