Please refer to FIG. 1 to FIG. 3 , a vertical oil mist filtering device provided by the present invention, which is mainly composed of a body 11 , a first filter group 21 , a motor 31 , and a second filter group 4 . ,among them:
The main body 11 is a hollow casing, and has a first air chamber 12, a second air chamber 13 and a third air chamber 14 sequentially connected to the inside of the body 11, wherein the third air chamber 14 is provided. Above the first gas chamber 12 and the second gas chamber 13. An air inlet 121 is formed in the front end surface of the first air chamber 12 to communicate with the external space. The first air chamber 12 defines a first discharge hole 122 at the bottom. The second air chamber 13 is located at the rear side of the first air chamber 12, and a second discharge hole 133 is defined in the bottom of the second air chamber 13. The front side of the second air chamber 13 has an air inlet 131, and the first air chamber 12 communicates with the second air chamber 13 via the air inlet 131, and the top of the second air chamber 13 is provided with The third air chamber 14 communicates with the communication hole 132, and an air outlet 142 is defined at the top of the third air chamber 14.
The first filter group 21 is disposed in the first air chamber 12 of the body 11 . In the embodiment, the first air chamber 12 is respectively provided with an opening 123A, 123B on the left and right sides of the body 11, and each of the openings 123A, 123B is respectively provided with a cover 124 for the movable closing opening, and One of the covers 124 is provided with a pressure gauge 125 connected to the first air chamber 12. The first filter group 21 can be assembled into the first air chamber 12 from the opening 123A on the left side of the body 11 as shown in FIG. 4, or from the opening 123B on the right side of the body 11 as shown in FIG. Enter the first air chamber. Accordingly, even if the creation is set in an environment of a narrow space, a more convenient opening can be selected for the assembly of the first filter group 21; on the other hand, when cleaning the creation, a more convenient one can be selected. The opening extends the cleaning device into the cleaning, which improves the convenience of use.
The first filter group 21 includes at least one stainless steel defogging net 24 and at least one filter cotton sheet 25 in a frame 22, and the air inlet of the first filter group 21 and the first air chamber 12 121 is oppositely disposed, and the filter cotton sheet 25 is disposed opposite to the air inlet 131 of the second air chamber 13.
In addition, a bottom of the first air chamber 12 is provided with a support frame 5 for being placed under the first filter group 21. In detail, the width of the support frame 5 corresponds to the frame 22 of the first filter group 21, and a baffle 51 is disposed on one side of the support frame 5 to limit the displacement of the first filter group 21. On the other hand, the bottom of the first air chamber 12 is partitioned by the support frame 5 to form an oil collection area 126 for collecting oil droplets filtered by the stainless steel defogging net 24 and the filter cotton sheet 25. Moreover, the first discharge hole 122 is connected to the oil collection area 126 for the oil droplets of the oil collection area 126 to be discharged from the first discharge hole 122.
The motor 31 is disposed at an appropriate position outside the rear side of the second air chamber 13, and the motor 31 is provided with a fan wheel, wherein the fan wheel can be a scroll fan 32 as shown in FIG. 2 or as the sixth The centrifugal fan wheel 33 shown in the figure is embodied. As shown in FIG. 3, the fan wheel 32 extends in the second air chamber 13 and is disposed opposite to the air inlet 131.
The second filter group 4 is disposed in the third air chamber 14 and includes at least one filter cotton sheet 42, and the second filter group 4 is filtered by a finer pore than the filter paper sheet 25 of the first filter group 21 The cotton sheet 42 is constructed to filter impurities in the air to remove odor. The filter cotton sheets 42 of the second filter group 4 are stacked in layers in the third air chamber 14 in a lateral manner.
When the present invention is actually used, as shown in Fig. 3, the motor 31 is started to drive its fan wheel 32 to start operation. At this time, the external air located in the body 11 is drawn by the airflow formed by the rotation of the fan wheel 32, and enters the first air chamber 12 through the air inlet 121, and the oil mist dust powder in the gas passes through the first After the demisting net 24 in the filter group 21 is blocked, the vortex generated by the fan wheel 32 is further concentrated to increase the concentration of the particles in the gas to improve the filtering effect of the gas passing through the filter groups 21 and 4, and then pass through. The gas of the first filter group 21 is further driven by the blades of the fan wheel 32, and enters the third gas chamber 14 via the communication hole 132 of the second gas chamber 13, at which time the gas is subjected to the second filter group 4. The second stage of filtration is performed, and finally discharged from the air outlet 142. Further, the oil mist sucked into the interior of the body 11 by the fan wheel 32 can be liquefied inside the body 11 by gravity and air flow, and discharged through the discharge holes 122 and 133.
This creation system uses a multi-stage filtration method to effectively collect and filter the oil mist in the gas, and can be recycled and reused through the discharge hole, so it is environmentally friendly and can effectively reduce the cost of cutting oil, and through this creation The multi-stage filtration function can effectively filter the oil mist, smoke and odor which are diffused in the air, and achieve the air purification effect of completely filtering the oil mist and dust.
Furthermore, the creation can utilize the pressure gauge 125 on the cover 124 to determine whether the filter material should be replaced. As shown in FIG. 1, the pressure gauge 125 is provided with an index ball 128. When the fan wheel 32 is actuated to draw outside air into the interior of the body 11, the air pressure in the first air chamber 12 will be lower than the external air pressure. The index ball 128 of the gauge 125 will float to represent the pressure state within the first plenum 12. However, after using this creation for a period of time, the oil mist in the air will accumulate on the filter material and cause blockage, thereby reducing the filtering effect. If the above situation occurs, the air pressure in the first air chamber 12 will approach the external air pressure, and the height of the index ball 128 of the pressure gauge 125 will be lower, and the user can judge that the filter material is blocked. Replace it in time to maintain good filtration.
However, the disclosure of the above embodiments is intended to illustrate the present invention and is not intended to limit the present invention, so the replacement of equivalent elements should still be within the scope of this creation.
In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
