Abstract
The invention discloses a DPA environment-friendly paint mist filter cotton, which comprises an air inlet surface, a filter grid layer and environment-friendly paint mist cotton, wherein the bottom of the air inlet surface is provided with the filter grid layer, the bottom of the filter grid layer is provided with the environment-friendly paint mist cotton, the air inlet surface is of a diamond grid structure, the DPA environment-friendly paint mist filter cotton is mainly characterized by having a duplex structure, improving the trapping and adsorbing capacity for paint mist and oil smoke, further improving the filter efficiency of the filter cotton, reducing resistance and increasing strength, and the unique 3D diamond pocket design of the filter cotton ensures that the DPA paint mist cotton catches a large amount of excessive spray before the pressure difference reaches the replacement indication, so that the structural function can not only obtain the highest filter efficiency, but also can ensure that the DPA paint mist cotton is used online in an optimal efficiency area, and the improved filter efficiency means that the amount of over-sprayed paint is more captured each time, and allows for longer intervals between filter changes.
Description
Technical Field
The invention relates to paint mist filter cotton, in particular to DPA environment-friendly paint mist filter cotton, and belongs to the technical field of filter cotton.
Background
The DPA paint mist filter cotton is also generally arranged at the bottom of the paint spray booth and is very important as an air outlet of the whole paint spray booth. At present, glass fiber paint mist filter cotton, also called paint mist felt, is generally used, and the filter cotton needs to be replaced once in about one week so as to ensure the clean environment of the whole paint spraying room. The environmental cleanliness of a paint spray booth is crucial to the paint spray quality of people, so when selecting the filter cotton, the quality must be considered, the cost is not a problem, and finally the exhaust gas cannot meet the environmental protection requirement due to the selection of the filter cotton with low cost.
Disclosure of Invention
The invention aims to provide DPA environment-friendly paint mist filter cotton to solve the problems in the background art.
In order to achieve the purpose, the invention provides the following technical scheme: DPA environmental protection coating cloud filters cotton, including air inlet face, filtration net layer environmental protection coating cloud cotton, the bottom of air inlet face is equipped with filters net layer, the bottom of filtering net layer is equipped with the environmental protection coating cloud cotton, the air inlet face is rhombus grid structure.
As a preferred technical scheme of the invention, the filtering grid layer is of a rhombic grid structure, and the rhombic grid is wide at the top and narrow at the bottom and has the size of 60mm multiplied by 35 mm.
As a preferred technical scheme of the invention, the filter grid layer and the environment-friendly paint mist cotton are formed by heating and pasting, and the thickness of the filter grid layer is 20mm-60 mm.
As a preferred technical scheme of the invention, the bottom of the filter screen grid layer is of a directional structure, the thickness of the filter screen grid layer is 10mm-30mm, the filtration grade is G1(DIN24185) and the fire-retardant grade is F-1(DIN 53438).
As a preferable technical scheme of the invention, the diameter size of the paint particles captured by the environment-friendly paint mist cotton is 2.5-10 microns.
Compared with the prior art, the invention has the beneficial effects that: the invention discloses a DPA environment-friendly paint mist filter cotton which is mainly characterized by having a duplex structure, improving the trapping and adsorption capacity of paint mist and oil smoke, further improving the filtering efficiency of the filter cotton, reducing resistance and increasing strength, and due to the unique 3D diamond pocket design, the DPA paint mist filter cotton can already trap a large amount of excessive spray before the pressure difference reaches a replacement indication.
Drawings
FIG. 1 is a schematic diagram of a structural layer of the present invention;
fig. 2 is a schematic top view of the present invention.
In the figure: 1. an air inlet surface; 2. a filtration mesh layer; 3. environmental protection lacquer fog cotton.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides DPA environmental protection paint mist filter cotton,
the first embodiment comprises an air inlet surface 1, a filter screen grid layer 2 and environment-friendly paint mist cotton 3, wherein the filter screen grid layer 2 is arranged at the bottom of the air inlet surface 1, the environment-friendly paint mist cotton 3 is arranged at the bottom of the filter screen grid layer 2, and the air inlet surface 1 is of a rhombic grid structure.
The filter screen grid layer 1 is of a rhombic grid structure, the rhombic grid is wide at the upper part and narrow at the lower part, and the size is 60mm multiplied by 35 mm.
In the second embodiment, the filtering mesh layer 2 and the environmental protection paint mist cotton 3 are formed by heating and pasting without using any glue, the traditional industry is formed by pasting the EVA hot melt adhesive and the bottom filtering layer, thus the environmental protection requirement cannot be met, and the thickness of the filtering mesh layer 1 is 20mm-60 mm.
The bottom of the filtering mesh layer 1 is of a directional structure, the thickness of the filtering mesh layer is 10mm-30mm, the filtering grade is G1DIN24185, and the fire-retardant grade is F-1(DIN 53438).
The environmental mist cotton 3 captures paint particles having a diameter size of 2.5 microns to 10 microns, and the particles in this range represent the size of overspray mist generated during the spraying operation, and the DPA mist filter can effectively capture and retain the paint mist particles to prevent them from contaminating downstream equipment.
In summary, the 3D diamond pocket design, i.e., the diamond hole design, allows the DPA lacquer mist cotton to capture a large amount of excess spray before the pressure differential reaches the change indicator. The structural function can not only obtain the highest filtering efficiency, but also enable the DPA paint mist cotton to be used online in an optimal efficiency area, and the improved filtering efficiency means that the amount of the paint mist caught each time is more, and the time interval between filter replacement is longer.
