Fig. 2 is the enlarged diagram of the present invention first sealing and the second sealing position.
Wherein: mainboard 1, subplate 2, secondary frame 3, filter chamber 4, material channel 5, avoiding hollow groove 6, first sealing 71, second sealing 72, limiting section 8, fixture 9.
Detailed description of the invention
The invention will be further described with the following Examples.
A kind of filter press filter board of slot type hermetically-sealed construction, comprise filter plate body, before or after described filter plate the edge of side be provided with for described filter plate contact with each other sealing protuberance, described protuberance inner space is filter chamber 4, described filter plate is provided with material channel 5 and drainage passage, and described filter plate is provided with at the position that contacts with each other the avoiding hollow groove 6 reducing contact area.
Maintain constant pressure between filter plate is constant, the protuberance of described filter plate and adjacent described filter plate contact surface, i.e. sealing surface, its area is less, and the pressure that unit are obtains is larger.Utilize this principle, avoiding hollow groove 6 is set at its sealing surface, effectively can increase sealing effectiveness.When discharging, if there is a small amount of material to remain in the edge of filter plate side, described avoiding hollow groove 6 can receive residual material, prevents the material clamp remained between filter plate, affects the sealing property between filter plate.
Described filter plate comprises mainboard 1, subplate 2 and secondary frame 3, and described subplate 2 is fixed on the front side of described mainboard 1; Described secondary frame 3 is described protuberance, and described secondary frame 3 is socketed on the outside of described subplate 2 and can slides axially, and makes described filter chamber 4 become the press filtration space of variable volume; Flexible member is provided with between described mainboard 1 and secondary frame 3; Described avoiding hollow groove 6 is located at the front side of described secondary frame 3, or the position of the corresponding described secondary frame 3 of the rear side of described mainboard 1.
The described mainboard 1 of the described subplate 2 of described filter plate, secondary frame 3 and adjacent described filter plate forms filter chamber 4, and slidably described secondary frame 3 makes the variable volume of described filter chamber 4, after filler press filtration, further raising pressure, make the volume reducing of described filter chamber 4, the Interstitial Water of further squeezing material, reduces the moisture content of described material.
The front side of described secondary frame 3, or the position of the corresponding described secondary frame 3 of the rear side of described mainboard 1 is provided with the first sealing 71; The second sealing 72 is provided with between described subplate 2 and described secondary frame 3.Described first sealing 71 improves the sealing property of described filter 4 Room, prevents material from revealing whitewashing; Described second sealing 72, is prevented material from being revealed by the gap between described subplate 2 and secondary frame 3, thus corrodes described elastomeric element.
Described first sealing 71 is sealing ring, be located at described avoiding hollow groove 6 comparatively inner side position.Such structure is conducive to improving sealing property.
Described second sealing 72 is sealing ring more than twice or twice, and described second sealing 72 is located at the non-edge place of described subplate 2 or secondary frame 3.The multiple-sealed circle of described second sealing 72, improves sealing property, and the consideration of its position, be because if the edge of described subplate 2 or secondary frame 3 is located at by described sealing ring, easy loss, service life is short.
Described mainboard 1, subplate 2 and secondary frame 3 is arrange with one heart.Material channel 5 is located at center, and material can be filled into rapidly in described filter chamber 4 uniformly.
Described mainboard 1, subplate 2 or secondary frame 3 is square or circular.From cost or otherwise consideration, according to the difference of design, described mainboard 1, subplate 2 or secondary frame 3 is square or circular, is all for structure of the present invention.
The contact site of described subplate 2 and secondary frame 3 is respectively equipped with limiting section 8, and described in two places, limiting section 8 cooperatively interacts, and limits described secondary frame 3 and emerges in described subplate 2.
Described limiting section 8 is spacing ring, and the top of the contact site of two described spacing rings is or/and root corner is provided with rounding.The structure of described rounding, makes the slip of described secondary frame 3 more level and smooth, and reduces power-assisted.
The front side of the rear side and described subplate 2 of being close to described mainboard 1 is respectively equipped with filter screen, the surface coverage filter cloth of described filter screen, and the edge of described filter cloth is fixed on described mainboard 1 or described subplate 2 by fixture 9; Be positioned at the described fixture 9 of described subplate 2 and described mainboard 1, its position is symmetrical, and is located at the inner side of the delivery position of described subplate 2 and described secondary frame 3.The scope that material is filled does not cover the gap between described subplate 2 and secondary frame 3, prevents described material to be leaked to described elastomeric element, corrosion elastomeric element.Described fixture 9 position of filter plate both sides is symmetrical, and the power that filter plate both sides are received is balanced, makes structure more stable.Described filter cloth does not provide in Figure of description.Described fixture 9 comprises screw, retainer plate and sealing ring.
Finally should be noted that; above embodiment is only for illustration of technical scheme of the present invention but not limiting the scope of the invention; although be explained in detail the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
