Description
Technical field
The utility model relates to the withstand voltage porous plate of one for liquid filter.
Background technology
Porous plate is the common components in liquid filter, is commonly called as " card ".The structure of the liquid filter used at present is: comprise tank body, tank interior is separated into the upper chamber of mutual seal isolation, filter chamber and lower chambers by upper face plate and lower face plate, between upper face plate and lower face plate, some screen pipes are vertically installed, upper chamber is connected by screen pipe with lower chambers, the outer wall of upper chamber offers water inlet, the outer wall of filter chamber offers delivery port.The operation principle of aforesaid liquid filter is: enter upper chamber in water impurity from water inlet and enter lower chambers by screen pipe, after water impurity is full of lower chambers, along with water impurity continue pass into, water impurity can appear screen pipe under external pressure, appear in the process of screen pipe in water impurity, the fine particle impurity that waits in water impurity can be attached to screen pipe surface, and the water impurity after chimney filter filters then enters filter chamber and discharges tank body from delivery port; After liquid filter runs a period of time, the impurity be attached on screen pipe inwall can get more and more, and then affect the filter efficiency of screen pipe, now need to carry out backwash operation, that is: backwash water enters from delivery port, more inwardly penetrates screen pipe from filter chamber, and then discharges tank body from water inlet.The shortcoming of aforesaid liquid filter is: the compressive resistance of card is low, upper face plate and lower face plate can only bear the intake pressure of 0.2-0.4KPa, in the filtration and backwash process of water impurity, the water inlet instantaneous pressure scope of water impurity and backwash water is 0.4-0.5KPa, thus make upper face plate or lower face plate easily occur up and down reciprocatingly to vibrate, and then easily make the screen pipe be fixed between upper face plate and lower face plate damage from coming off between upper face plate and lower face plate, reduce the service life of liquid filter.
Utility model content
The purpose of this utility model is to provide the high and withstand voltage porous plate of one that can extend liquid filter service life of a kind of compressive resistance.
For achieving the above object, the utility model have employed following technical scheme: a kind of withstand voltage porous plate, comprise the porous plate body evenly offering some filter bores, the latticed reinforcement be interspersed by some stiffeners is provided with at the top of porous plate body, the stiffener of latticed reinforcement is without the filter bores aperture of porous plate body, the thickness of described porous plate body is 10-18mm, the thickness of described stiffener is 10-18mm, the height of described stiffener is 100-150mm, and the spacing between two adjacent, parallel stiffeners is 420-840mm.
Further, aforesaid one is withstand voltage porous plate, wherein: the thickness of described porous plate body is 16m, the thickness of described stiffener is 16mm, and the height of described stiffener is 130mm, and the spacing between two adjacent, parallel stiffeners is 650mm.
By the enforcement of technique scheme, the utility model has the high and advantage that can extend liquid filter service life of compressive resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of withstand voltage porous plate described in the utility model.
Fig. 2 is the structural representation of the A-A section shown in Fig. 1.
Fig. 3 is the structural representation of the B-B section shown in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, described one is withstand voltage porous plate, comprise the porous plate body 1 evenly offering some filter bores, the latticed reinforcement be interspersed by some stiffeners 2 is provided with at the top of porous plate body 1, the stiffener 2 of latticed reinforcement is without filter bores 3 aperture of porous plate body 1, the thickness a of described porous plate body 1 is 10-18mm, the thickness b of described stiffener 2 is 10-18mm, the height d of described stiffener 2 is 100-150mm, and the spacing c between two adjacent, parallel stiffeners 2 is 420-840mm, in the present embodiment, the thickness a of described porous plate body 1 is 16mm, the thickness b of described stiffener 2 is 16mm, the height d of described stiffener 2 is 130mm, spacing c between two adjacent, parallel stiffeners 2 is 650mm, the compressive resistance of this withstand voltage porous plate is high, the intake pressure of 0.5KPa can be born, like this in the filtration and backwash process of water impurity, withstand voltage porous plate not easily occurs up and down reciprocatingly to vibrate, and then the screen pipe of liquid filter can not be made from coming off between upper and lower two withstand voltage porous plates and damaging, substantially increase the service life of liquid filter.
