Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Referring to fig. 1 and 2, the present invention provides a combined type large capacity dry carton filter, which comprises an outer frame 100, and a first inner frame 200 and a second inner frame 300 located in the outer frame 100. The opposite sides of the outer frame 100 are provided with air guide openings respectively opposite to the first inner frame 200 and the second inner frame 300, and the air sequentially passes through the first inner frame 200 and the second inner frame 300, so as to remove paint mist particles in the air.
The outer frame 100 is an outer shell, and may be formed by cutting 3 layers of corrugated cardboard to form a hollow rectangular structure. The outer frame 100 may be formed of other materials.
The first inner frame 200 is substantially rectangular in shape as a whole. The first inner frame 200 includes two limiting plates 210 arranged in parallel up and down and a V-shaped wing panel 220 penetrating the two limiting plates 210. The V-shaped wing edge plate 220 is formed by oppositely bending two open ends of the V-shaped plate, the side surface of the V-shaped wing edge plate 220 is provided with a rectangular vent hole, and the rectangular vent hole is shielded by the wing edge of the V-shaped wing edge plate 220. To ensure the ventilation efficiency of the rectangular ventilation holes and the structural strength of the V-shaped wing panel 220, two rectangular ventilation holes are provided at each side of the V-shaped wing panel 220.
Limiting plate 210 is provided with a jack matched with V-shaped wing sideboard 220, and a plurality of V-shaped wing sideboard 220 are at limiting plate 210's length direction evenly distributed, and the tip of V-shaped wing sideboard 220 sets up in the inconsistent, and V-shaped wing sideboard 220 arranges to the other end from limiting plate 210's one end.
In this embodiment, the limiting plate 210 and the V-shaped wing plate 220 can be formed by combining 3 layers of corrugated cardboard.
The gas containing paint mist particles on the outside can enter the inside of the V-shape through the V-shaped wing plates 220, and the backflow is guided into the structure of the second inner frame 300 through the rectangular vent holes on the V-shaped wing plates 220.
The second inner frame 300 is specifically configured as a W-shaped plate structure, the second inner frame 300 is vertically placed, and the second inner frame 300 may be specifically formed by combining 3 layers of corrugated cardboard.
A rectangular air guide hole is formed in the W-shaped structural side plate of the second inner frame 300, a large dust-containing polyester filter layer is attached to the second inner frame 300, and the large dust-containing polyester filter layer is attached to one side face, close to the first inner frame 200, of the second inner frame 300; thus, the air filtered by the first inner frame 200 is guided into the structure of the second inner frame 300, the paint mist contained in the air firstly passes through the large dust-containing polyester filter layer for filtering and intercepting, and then the air flow is discharged through the rectangular air guide hole on the second inner frame 300. Specifically, the polyester filter material may be glass fiber filter cotton.
Both sides of the second inner frame 300 respectively abut against the limiting plate 210 and the outer frame 100, and both ends of the second inner frame 300 abut against the outer frame 100.
In this embodiment, to ensure the structural strength of the second inner frame 300, two connecting plates 310 are fixed to the side of the second inner frame 300 away from the first inner frame 200, the connecting plates 310 are horizontally disposed, and the connecting plates are connected to the outer frame 100.
The first and second inner frames 200 and 300 may be directly placed inside the outer frame 100.
The first and second inner frames 200 and 300 are prevented from shaking within the outer frame 100 because the first and second inner frames 200 and 300 are in contact with each other and the connection plate 310 is fixed to the second inner frame 300.
Like this, through the setting of above-mentioned structure, V-arrangement structure on this application through first inner frame 200 for have great space in the first inner frame 200, can allow the air current to have certain buffering, so structural resistance is little, greatly reduced the structural resistance of product.
In addition, a large dust-containing polyester filter layer is additionally arranged in the W-shaped structure on the second inner frame 300, so that the paint containing capacity and the paint containing area are increased, and the filtering precision of paint mist and impurities is greatly improved.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
