Abstract
The utility model provides a kind of hexagon mesh-structured conical filter net, a kind of mesh-structured conical filter net of hexagon, the conical filter net is put together by three and above sector screen pack, the wire side perforate of the conical filter net is hexagon, and the hexagon mesh in plane after the conical filter net unfolding is evenly arranged.The conical filter net of the hexagon mesh has advantages below compared to prior art：1. the circulation area of unit wire side is bigger, filter screen water resistance is smaller；2. the intensity of filter screen is higher；3. the discharge ability of pair particulate contamination is stronger, it is not easy to wind, bonds, deposit dirt and impurity, filter screen is not easily blocked and is easier to clear up.
Description
Technical field
A kind of screen pack for being used for the online rubber ball cleaning system ball screen of condenser and secondary filter is the utility model is related to,
More particularly, to a kind of mesh-structured conical filter net of hexagon.
Background technology
Most of ball screen of the online rubber ball cleaning system of condenser is the grid plate structure or use punching that steel bar is worn at present
Press circular hole, the structure of strip hole.These mesh-structured generally existing unit wire side circulation areas are small, water resistance is big, Yi Kaqiu, collect
Rate is low, the problems such as easily bonding, deposit, winding debris and be difficult to clean up.These problems cause the online rubber ball cleaning system of condenser
Using effect is extremely undesirable, and causing condenser to run, vacuum is low, end difference is high, is restricted units consumption increase, generation load.
It is to use punching press borehole structure mostly at present as secondary filter.The structure equally exists unit wire side circulating face
The small, water resistance of product is big, the problems such as bonding, deposit, winding debris and be difficult to clean up.It must be shut down when mesh blocking is serious or half side
The debris of isolation ability manual cleaning screen surface, great danger is caused to the security and continuity of Power Plant operation
Evil.
Therefore, research and develop a kind of unit circulation area is bigger, water resistance is smaller, the less susceptible to plugging screen pack of mesh have it is important
Meaning.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model discloses a kind of mesh-structured taper of hexagon
Filter screen, it is thoroughly solved, and unit wire side circulation area is small, water resistance is big, bond, alluvial, winding debris and is difficult to clean up etc. asking
Topic.
A kind of mesh-structured conical filter net of hexagon, the conical filter net are spelled by three and above sector screen pack
Conjunction forms, and the wire side perforate of the conical filter net is hexagon, the hexagon in plane after the conical filter net unfolding
Mesh is evenly arranged.
The conical filter net is stainless steel.
The hexagon mesh is punching hole.
The width of spacer bar between the hexagon mesh and adjacent hexagonal mesh is equal.
The land side of the conical filter net is welded with reinforcement along generatrix direction and circumferencial direction.
The round edge of the punching hole is in the side that meets water of conical filter net, and wedge angle side is in land side.
The mode of more than the three fan-shaped screen pack splits is bolt connection.
Do Passivation Treatment in the wedge angle side of the punching hole.
A kind of mesh-structured conical filter net of hexagon disclosed in the utility model has the advantages that：
1. the circulation area of unit wire side is bigger, and up to more than 70%, filter screen water resistance is smaller；
2. the intensity of filter screen is higher；
3. the discharge ability of pair particulate contamination is stronger, it is not easy to wind, bonds, deposit dirt and impurity, filter screen is not easy to block up
Plug and easily cleaning.

Embodiment
The utility model is described by the following examples, it should be noted that cited embodiment should not be construed as
Limitation to utility model.
Specific embodiment of the present utility model is described in detail below.
As shown in figure 1, the conical filter net that a kind of hexagon of the present embodiment offer is mesh-structured, the filter of the filter screen 1
The perforate of net wire side 11 is hexagon mesh 2, and perforate is as shown in Figure 2.
The conical filter net is stainless steel, and the hexagon mesh 2 is punching hole.The conical filter net unfolding
Hexagon mesh 2 in plane afterwards is evenly arranged.Spacer bar 3 between the hexagon mesh 2 and adjacent hexagonal mesh 2
Width is equal.
As shown in figure 4, the conical filter net is put together by three fan-shaped screen packs.As shown in figure 3, the taper
The land side 13 of filter screen is welded reinforcement 4 along generatrix direction and circumferencial direction.The round edge of the punching hole is in conical filter
The influent side 12 of net, wedge angle side is in land side 13.The mode of more than the three fan-shaped screen pack splits is that bolt 5 connects.Institute
Do Passivation Treatment in the wedge angle side for stating punching hole.A kind of mesh-structured conical filter net of hexagon of the present embodiment, is used as ball screen
When, the area of hexagon mesh 2 is 0.6~0.7 with the ratio range of glueballs maximum secting area；When being used as secondary filter, hexagonal
The inscribed circle diameter scope of shape mesh 2 is 4mm~8mm.The width of the spacer bar 3 is 2mm.
The present embodiment has the advantage that compared with prior art：
1. the circulation area of unit wire side is bigger, and up to more than 70%, filter screen water resistance is smaller；
2. the intensity of filter screen is higher；
3. the discharge ability of pair particulate contamination is stronger, it is not easy to wind, bonds, deposit dirt and impurity, filter screen is not easy to block up
Plug and easily cleaning.
Embodiment of the present utility model is elaborated above.But the utility model is not limited to above-mentioned implementation
Mode, in art those of ordinary skill's possessed knowledge, the utility model ancestor can also not departed from
Made a variety of changes on the premise of purport.
