Embodiment Construction
[0013] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention but not to limit the scope of the present invention. Such as Figure 1-4 As shown, a novel filter screen plate includes a tight filter screen main body 1, and the filter screen main body 1 is formed by a number of circular holes 11 evenly distributed and formed into a first filter screen, in which the first filter screen Each filter hole 11 is provided with a plurality of small holes downwards to form the second filter mesh hole 2 .
[0014] The aperture of the second filter mesh 2 is between 0.05mm-2mm.
[0015] The small holes of the second filter holes 2 are uniformly distributed to form a second filter screen.
[0016] The beneficial effect of the present invention compared with prior art is:
[0017] The present invention has two l...

The invention belongs to the technical field of filtration, and particularly relates to a novel filtering screen plate. The novel filtering screen plate comprises a filtering screen main body which is formed by a plurality of round holes distributed uniformly and forms a first filtering silk screen; each filtering hole in the first filtering silk screen is internally provided with a plurality of small holes downward so as to form a second filtering screen hole. The novel filtering screen plate provided by the invention is provided with the two layers of filtering screen holes, the first layer of filtering screen holes are the round holes; the novel filtering screen plate is made from a special metal material, and thus tens of thousands of holes can be drilled in the filtering screen plate; the filtration for the second layer is formed by the small holes in the first layer of filtering screen holes, and moreover, the diameters of the small holes can reach 0.05mm to the minimum, and can reach 2mm to the maximal, so that the secondary screening process is complete. Therefore, the filtering capability of the filtering plate is perfect, and the filtering plate is suitable for screening in each field. Tests prove that the novel filtering screen plate provided by the invention is very convenient to clean after being used, and is free of blocking.
Description
technical field [0001] The invention belongs to the technical field of filtration, in particular to a novel filter net plate. Background technique [0002] Now the common filter screens on the market are circular metal panels, and several regularly arranged through holes are punched out on the surface of the metal panels. The net is a single-layer structure without the ability of secondary screening. Contents of the invention [0003] The object of the present invention is to provide a filter screen plate which is easy to operate, safe and reliable, and can be adapted to many occasions. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a new filter screen plate, including a filter screen main body, the filter screen main body is formed by a number of circular holes evenly distributed and formed into a first filter screen, the first filter screen A number of small holes are arranged downwards in each filter ho...
