Abstract
Description
Technical Field
[0001] The utility model relates to the field of oil smoke filtering, in particular to an alloy filtering structure. Background Art
[0002] To enhance the effectiveness of oil-blocking, current range hoods on the market typically have a filter installed at the air inlet. The filter has mesh holes or spokes, allowing oil smoke to pass through the filter before entering the range hood, where it condenses and effectively blocks the oil. Traditional filters are unable to effectively remove oil from oil smoke, resulting in low oil fume purification efficiency. Furthermore, over time, the viscosity of the particles and oil droplets captured by the filter increases, leading to increased pressure drop in the filter layer, increasing resistance, and excessive power consumption.

[0019] Below with reference to the embodiment and the attached Figures 1 to 5 , the technical solution of the utility model is further elaborated.
[0020] Example 1
[0021] An alloy filtering structure includes: a base 1, an upper cover 2 and a corrosion-resistant foam metal filter plate 3, wherein the base 1 and the upper cover 2 are both provided with an air inlet 4 in the middle, the inner side of the base 1 is provided with a rectangular groove 11, the rectangular groove 1 is provided with a circular groove 12, a magnet 13 is fixed in the circular groove 12, the inner side of the upper cover 2 is provided with a rectangular protrusion 21 matching the rectangular groove 11, the corrosion-resistant foam metal filter plate 3 is arranged in the rectangular groove 11, a magnet 2 31 is fixed at the bottom of the corrosion-resistant foam metal filter plate 3, the magnet 2 31 is magnetically connected to the magnet 13 and is located in the circular groove 12, the upper cover 2 is provided with a fixing bolt 51 fixedly connected to the base 1, and the outer side of the base 1 is provided with an external fixing bolt 5.
[0022] like Figures 1 to 5 As shown, the working principle of the present invention is as follows: the corrosion-resistant foam metal filter plate 3 is used as the filtering structure, which is generally foam nickel, foam copper, and foam iron nickel; this material has a special three-dimensional void structure, and the porosity is usually more than 90%, which can provide excellent permeability while maintaining low pressure loss, and has high low static pressure adsorption performance. It adopts the filtering mechanical separation principle. When the oil smoke passes through the filter, the large particles in the oil smoke are intercepted by these channels, thereby realizing the filtration of the oil smoke, and the oil smoke particles are collided on the filter by inertia force, so that the gas is separated. The three-dimensional porous structure of the foam metal makes the oil smoke particles not only intercepted on the surface when passing through the filter, but also It is captured and adsorbed deep inside the material; when the wind speed is 1.6m / s, the pressure loss is only 15Pa, which ensures the smooth exhaust of the kitchen, and the large specific surface area and appropriate roughness of the material increase the collision probability of the fume particles, thereby significantly improving the purification efficiency; it solves the weaknesses of the filtration and adsorption control technology in the application of oil smoke, such as the difficulty of self-flow and large pressure drop, and solves the problem of low capture efficiency, achieving the effect of ventilation and separation, which can maximize the adsorption of oil smoke, improve the air environment, and make it basically impossible for oil smoke to reach the purifier at the end of the flue, greatly reducing the number of cleaning times of the flue, purifier, and fan, and avoiding the "zombie machine" phenomenon of the purifier.
[0023] The corrosion-resistant foam metal filter plate 3 is adsorbed on the magnet 13 of the rectangular groove 11 of the base 1 through the magnet 2 31, so that the corrosion-resistant foam metal filter plate 3 can be fixed to the rectangular groove 11, and then the upper cover 2 is fixed to the base 1 through the fixing bolt 1 51, thereby clamping the internal corrosion-resistant foam metal filter plate 3, and the base 1 is fixed to the range hood through the external fixing bolt 5; when the corrosion-resistant foam metal filter plate 3 needs to be replaced, it is only necessary to remove the fixing bolt 1 51 and remove the upper cover 2 to take out the internal corrosion-resistant foam metal filter plate 3 without removing the base 1. The structure is simple and easy to install and maintain.
[0024] As a further preferred embodiment, the thickness of the corrosion-resistant metal foam filter plate 3 is 3 mm to 5 mm. The corrosion-resistant metal foam filter plate 3 in this thickness range can provide sufficient structural strength while maintaining low pressure loss and high permeability.
[0025] As a further preferred embodiment, the circular groove 12 , the first magnet 13 and the second magnet 31 are symmetrically arranged in four groups, thereby further improving the stability of the corrosion-resistant foam metal filter plate 3 in the rectangular groove 11 .
[0026] As a further preferred embodiment, the upper and lower volumes of the base 1 are provided with extension plates 14, and the external fixing bolts 5 are threadedly connected to the extension plates 14 and are symmetrically arranged in four groups, providing stronger fixing force, ensuring the stability of the filtering structure in the front section of the range hood, and also facilitating installation and maintenance.
[0027] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
