Embodiment
The invention will be further described with embodiment for explanation below in conjunction with the accompanying drawings, and mode of the invention includes but not only limits
In following embodiments.
The purpose of the present embodiment is to provide for refractory metal filter screen applied widely, as depicted in figs. 1 and 2,
The filter screen is included by frame made of metal material 1, some Right deviation oblique lines 2, some left-leaning oblique lines 3 and some reinforcement groups 4.
Specifically, square box or ring frame can be made as needed for the frame 1, also, the frame 1 can be around filter
The two rhizosphere zygonemas that the net structure edge of net is set, and the two rhizospheres zygonema is provided in lateral tilting oblique line upper and lower surface and phase
Mutually it is intertwined and connected, edge sealing can be played the role of, is on the one hand to avoid lateral tilting oblique line and the distal tip of reinforcement group from pinking
Hurt sb.'s feelings, make its security stronger and be more convenient for installing, another aspect is then but the monnolithic case of filter screen is more beautiful.The side
Frame 1 can also be arranged as required to the structure of the steel ring plate for bilayer, by the net structure border seal of filter screen at middle part.
The Right deviation oblique line 2 is to be uniformly arranged on 20~40 ° of angles in frame, and left-leaning oblique line 3 is then with 100~120 °
Angle is uniformly arranged in frame, and is alternating expression connection structure between Right deviation oblique line 2 and left-leaning oblique line 3, and described two adjacent
Right deviation oblique line 2 between spacing and two adjacent left-leaning oblique lines 3 between spacing it is consistent, therefore the filtering that can form diamond shape is led to
Filter hole can be arranged to diamond shape by hole, the setting, when filtering larger particles impurity, even if impurity is got lodged in filter hole, also not
The circulation of diamond shape corner can be hindered, does not interfere with current (filter hole will not be blocked) of filter medium, therefore will not be bright
It is aobvious to reduce filter efficiency, and also allow for making impurity go out with current during its backwash.
The reinforcement group 4 is horizontally installed in frame, and the adjacent two reinforcements group 4 forms repetitive unit, and repetitive unit
The spacing being smaller than between adjacent two repetitive unit between two interior reinforcement groups, every group of reinforcement group include setting respectively
Put in lateral tilting oblique line upper and lower surface and two wefts being mutually intertwined and connected；Weft in reinforcement group is mutually intertwined and connected, into
And can easily realize and be intertwined and connected with lateral tilting oblique line, play the role of strengthening filter screen toughness and stability.It is moreover, described
The spacing between spacing between two reinforcement groups and adjacent Right deviation oblique line 2 in repetitive unit is consistent, the adjacent repeat unit
Between spacing 2~5 times of spacing between adjacent Right deviation oblique line, therefore, the setting of the reinforcing rib, will not make same filtering area
The diamond shape filter hole in domain, which is concentrated, to be reduced, but makes it have enough intervals, and the diamond shape filter hole reduced is only a row, and is contracted
Several filter openings that are drained through are unchanged before and after that small row's diamond shape filter hole, therefore will not have an impact to filter efficiency；Also, it is not easy to send out
The raw phenomenon blocked (even if being blocked in the diamond shape filter hole of the diminution by relatively large granule foreign, also can aside filter Jie
Toward flowing through in the diamond shape filter hole on side under the drive of mass flow), the cleaning difficulty of filter screen will not be increased.
