Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a as shown in figure 1, figure 2, figure 3, figure 4 and figure 5 metal type reuse primary filter, including fixed framework 1, the protection network 2 is installed to fixed framework 1 both sides symmetry, the inside slip grafting of fixed framework 1 has filtering main part 3, fixed framework 1 side is provided with open end 4, fixed framework 1's inside bottom face mounting has fixed connection's guide rail groove 5, just guide rail groove 5 has seted up threely, sealed baffle 6 is installed to the inside upper end of framework, sealed baffle 6 is provided with twice shelves plectrum 7, shelves plectrum 7 will filter main part 3 and divide into first primary filter device 8, and second primary filter device 9 and third primary filter device 10 are imitated to the second. The guide rail structure 11 is installed to first just effective filter equipment 8, the first just effective filter equipment 9 of second and the first just effective filter equipment 10 lower extreme of third.

The first primary filter device 8 comprises an outer frame and a filter element 12 fixed in the outer frame, the outer frame is of an all-metal type, the filter element 12 is made of multiple layers of crossed and criss-cross wavy stainless steel woven meshes or multiple layers of different densities, and the aperture of the filter element is made of thick and thin expanded aluminum meshes. The filter material is packed in the cardboard in a folded form, dust particles in the inflowing air are blocked between the pleats by the filter material, and clean air flows out uniformly from the other side. The filter material is made of a plurality of layers of crossed and criss-cross wavy stainless steel woven meshes or aluminum woven meshes, and the standard size thickness is 1 inch and 2 inches. The thickness is about 46 mm-96 mm. The outer frame can be made of stainless steel frame or aluminum frame, is suitable for industrial ventilation equipment, has low pressure loss and high dust collection function, is easy to clean and maintain, and saves cost. The protective net 2 is a double-sided galvanized iron wire net. The protective net 2 can effectively protect the filter material from being damaged, prevent the filter material from being damaged due to wind resistance pressure, and has good universality due to the fact that a plurality of size designs are unified.

The application places of the all-aluminum air filter screen are as follows: the filter screen is the most economical and effective method for industrial air ventilation equipment, and the filter material is made of multiple layers of expanded aluminum screens with different densities (the pore diameter is coarse and fine), and the dust collection capacity and efficiency are quite good.

The application places of the all-stainless steel air filter screen are as follows: the filter screen has low pressure loss and high dust collecting capacity, and is suitable for industrial use. The filter material is composed of a plurality of layers of crossed longitudinal and transverse wave corrugated stainless steel nets, and is reinforced by two sides of the crossed steel bar filter material to increase the firmness of the filter material. The multi-layer filter material structure enlarges the surface area of the filter screen.

The first primary filter device 8, the second primary filter device 9 and the third primary filter device 10 can be the same or different, and the selection filter is determined according to the actual application and the working environment. When chemical corrosivity exists in the space needing filtering, the use requirement can be met only by the primary filter which is made of a filtering material with certain high chemical resistance. The first filter equipment 8, the second first filter equipment 9 and the third first filter equipment 10 that imitates are the same in specification and size, just the first filter equipment 8, the second first filter equipment 9 and the third first filter equipment 10 that imitates top all are located the inside of seal spacer 6. The fixed frame body 1 is rectangular or trapezoidal, and when the fixed frame body 1 is trapezoidal, the shape of the built-in filter is changed. The inside of fixed frame body 1 is seted up the draw-in groove with 6 looks adaptations of sealed baffle, just sealed baffle 6 passes through the draw-in groove slip joint in the inside of fixed frame. The fixed frame body 1 is made of a stainless steel frame or an aluminum frame.

The primary filter adopts an all-metal type, the maintenance means is simple, the dust on the filter layer can be cleaned by adopting a cleaning method, the maintenance purpose can be achieved, and after the maintenance is finished, the filter element 12 and the filter screen of the filter can be repeatedly utilized, so that the economic type of selecting the primary filter is very high, and more cost is not required to be consumed.

The working principle is as follows: the fixed outer frame of the metal type recycling primary filter is composed of a firm metal plate and is used for fixing the internal filter device, and the first primary filter device 8, the second primary filter device 9 and the third primary filter device 10 can be the same primary filter, can also be different types, and can also be used in combination with the primary filter, the intermediate filter and the high-efficiency filter. The inner catch 7 serves to hold the respective filter device, and the outer frame of the filter device serves to hold the folded filter insert 12. Filter core 12 can adopt the design of W shape pincher trees structure or stainless steel mesh grid and expansion aluminium net to constitute, the second is just imitated filter equipment 9 and the first filter equipment 10 filter core of third and can choose for use W shape pincher trees structural design, works as the filter area that can increase filter core 12 for W shape pincher trees structural design to increase filter core 12 holds the dirt volume, increase of service life improves filtration efficiency. When the filter element 12 is installed, the periphery of the filter element 12 is sleeved with the U-shaped groove of the outer frame for positioning, and then professional bonding glue is filled in the U-shaped groove, so that the periphery of the filter element 12 is bonded and fixed in the U-shaped groove fully, and air leakage or damage caused by wind resistance pressure is effectively prevented. The filter element 12 is made of a corrugated non-woven fabric material, and since the material is easy to bend, a metal net is required to be lined for supporting and forming, so that the non-woven fabric is prevented from deforming under the action of wind resistance pressure. Therefore, the invention has the advantages of simple and firm structure, convenient installation, less material consumption and low cost.

In addition, because the filter element 12 is arranged in the high-strength outer frame in a W-shaped wrinkle mode, the filter element has a large windward area, large dust particles in the inflowing air are effectively blocked between the pleats by the filter material, the clean air flows out from the other side, the air flow is smooth and uniform, and the resistance is low under the same air quantity effect, so that the energy-saving effect of the fan is achieved.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
