Abstract
The invention discloses a novel filter screen for a paper machine, and the filter screen comprises a mesh. The mesh is divided into a first mesh layer, a second mesh layer and a third mesh layer from the top to the bottom, and the first mesh layer is formed by the cross connection of metal wires, and the second mesh layer is formed by the cross connection of polyurethane rubber. The third mesh layer is formed by the inclined cross connection of polyester fibers. The three mesh layers are connected together through polyester fiber lines. The edge of the filter screen is provided with a frame. Compared with the prior art, the filter screen is advantageous in that the filter screen is made of three mesh layers, improves the impact resistance, reduces the abrasion degree, greatly prolongs the service life, achieves a better filtering effect through the mesh design, reduces the conditions that the grid mesh is blocked, and improves the production efficiency, reduces the production cost; the filter screen is fixed on the frame; the frame is fixed through bolts, to as to facilitate the replacement of the filter screen.
Description
Technical field
The present invention relates to paper technology apparatus field, be specifically related to a kind of novel papermaking machine drainage screen.
Background technology
Paper pulp filtering is requisite one procedure in paper-making process, and the quality of papermaking filter screen quality directly affects into
The quality of product paper, the speed of paper delivery and the cost of paper, at present, it is common to use filter screen be all single layer structure, this use
During there is a lot of deficiencies, drainage screen there will be the situation of abrasion along with the increase of the time of use, reduces drainage screen
Service life, if use single layer filter net, can consume faster its service life, need to often change, add into undoubtedly
This, and single layer filter net is in filter process, the situation of clogging the most often occurs, need to often be carried out, significantly drop
Low production efficiency, to this end, it is long to design a kind of service life, reduces the cost produced, and the drainage screen reducing clogging shows
Obtain particularly important.
Summary of the invention
The present invention solves the problems referred to above and a kind of novel papermaking machine drainage screen invented.
Technical scheme is as follows:
A kind of novel papermaking machine drainage screen, including grid, described grid is divided into ground floor grid, second layer net from top to bottom
Lattice and third layer grid, described ground floor grid is formed by connecting by wire cross, and described second layer grid is by polyurethane
Rubber interconnection forms, and described third layer grid is tilted interconnection by polyester fiber and forms, described ground floor grid
The size of upper mesh and density are more than size and density, the described second layer net of mesh on second layer grid and third layer grid
On lattice, the size of mesh and density are more than the size of mesh on third layer grid and density, and described three-layer network lattice are fine by polyester
Dimension line links together, and described drainage screen edge is provided with framework.
Further, described tinsel is stainless steel silk.
Further, the described mesh on ground floor grid is circular.
Further, the mesh on described second layer grid and third layer grid is rectangle.
Further, described framework is set to train wheel bridge and lower plate, is bolted on together.
Present invention advantage compared with the prior art is: the present invention uses three-layer network lattice to be made, ground floor grid material
Material is rustless steel, and second layer grid material is polyurethane rubber, and third layer grid material is polyester fiber, improves drainage screen
Resistance degree, slows down the degree of abrasion, substantially prolongs the service life of drainage screen, and the mesh on grid is set to from top to bottom
Circle and rectangle, the density of mesh is gradually increased from top to bottom, preferably plays the effect of filtration, reduces the blocked situation of mesh
Generation, improve production efficiency, reduce production cost, drainage screen is fixed on framework, and framework is bolted, and facilitates
The replacing of filter screen.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the network profile of the present invention.
Fig. 3 is the frame structure schematic diagram of the present invention.
In figure: 1 framework 2 ground floor grid 3 second layer grid 4 third layer grid 5 train wheel bridge 6 spiral shell
Bolt 7 lower plate.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is expanded on further explanation:
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of novel papermaking machine drainage screen, including grid, described grid is divided into from top to bottom
Ground floor grid 2, second layer grid 3 and third layer grid 4, described ground floor grid 2 is formed by connecting by wire cross, institute
The second layer grid 3 stated is formed by polyurethane rubber interconnection, and described third layer grid 4 is tilted to intersect even by polyester fiber
Connecing and form, on described ground floor grid 2, size and the density of mesh are more than mesh on second layer grid 3 and third layer grid 4
Size and density, on described second layer grid 3 size of mesh and density more than on third layer grid 4 mesh size and
Density, described three-layer network lattice are linked together by polyester fiber line, and described drainage screen edge is provided with framework 1.
Use three-layer network lattice to make, the most significantly alleviate the degree of wear, be that the service life of drainage screen obtains
Arrive effective prolongation, reduce production cost, the problem effectively alleviating drainage screen blocking, improve work efficiency.
Embodiment 2
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of novel papermaking machine drainage screen, including grid, described grid is divided into from top to bottom

The second layer grid 3 stated is formed by polyurethane rubber interconnection, and described third layer grid 4 is tilted to intersect even by polyester fiber
Connecing and form, on described ground floor grid 2, size and the density of mesh are more than mesh on second layer grid 3 and third layer grid 4
Size and density, on described second layer grid 3 size of mesh and density more than on third layer grid 4 mesh size and
Density, described three-layer network lattice are linked together by polyester fiber line, and described drainage screen edge is provided with framework 1.
Further, described tinsel is stainless steel silk.
Further, the described mesh on ground floor grid 2 is circular.
Further, the mesh on described second layer grid 3 and third layer grid 4 is rectangle.
