Abstract
The utility model relates to a filter plate of a sheet frame press filter; both the front and the back surfaces of a filter plate are provided with a filter cavity which is used for accommodating the mud, and the bottom surface of the filter cavity is provided with projected particles, and the outer circumference of the filter cavity is provided with a flowing-out through hole which is used for the filter liquid to flow out, and a communication hole which is used for leading the filter liquid of the filter cavity into the flowing-out hole is arranged between the flowing-out through hole, and the central position of the filter cavity is provided with a filling through hole which is used for filling the mud, and the projected particles are uniformly distributed outwards from the mud filling through hole of the press filter in a spiral form. The filter plate of the sheet frame press filter has the advantages that the resistance force of the projected rubber particles is reduced, and the fluidity of the mud which is filled into the filter cavity is increased, thereby more effectively ensuring the uniformity of the mud inside the filter plate, and effectively preventing the inflation of the plate under the high pressure.
Description
Technical field
The present invention relates to a kind of filter plate that is applied on the plate and frame filter press.
Background technology
Mud is after conditioning, and the colloid apparent coagulation has had Separation of Solid and Liquid condition preferably, but very the moisture in the mud will be disengaged, and also needs mud is made processed.The plate compression dehydration is the most frequently used mechanical dehydration mode.
The effect of plate and frame filter press filter plate projection particle is the variation that forms local pressure around projection, to improve the effect of press filtration.The projection particle can hinder flowing of mud when mud injected filter chamber, and the distribution of protruding particle is just very important.The filter plate of existing plate and frame filter press, the close protruding particle that is located at the filter chamber bottom distributes along the central through hole concentric circles that injects mud.Because mud injects filter press with rotation mode under the effect of high-pressure pump, and protruding particle distributes along concentric circles, so protruding particle is very big to the resistance of mud, and it is poor to inject the flowability of mud in filter chamber.The filter plate that uses protruding particle to distribute along concentric circles, the average moisture content of filter cake is about 70%, each position moisture content of filter cake is extremely inhomogeneous, and irregular.Filter cake moisture content inhomogeneous, because mud skewness in the filter plate filter chamber causes, mud many positions that distributes, filter cake moisture content is low, and the pressure that filter plate bears is big.The position that the mud distribution is few, the pressure that filter cake moisture content height, filter plate bear is little.Moisture is low, is low to moderate 62.3%, and is high, up to 79.7%.The inhomogeneous filter plate discontinuity that causes of moisture content.When even, what be subjected to only is vertical positive pressure stressed on the two sides of filter plate, and a lot of materials can both be born, but when filter cake moisture content is inhomogeneous, what filter plate bore is the shearing force that acts on different parts, and this is destructive, produces the main cause of " plate bursting " phenomenon when this also is high pressure.
Summary of the invention
The purpose of this utility model is for a kind of filter plate that can make the plate and frame filter press that mud is evenly distributed in the filter plate filter chamber is provided.
Realize the filter plate of plate and frame filter press of the present utility model, be provided with the filter chamber of ccontaining mud at the tow sides of filter plate, be densely covered with protruding particle in the bottom surface of filter chamber, periphery at filter chamber is provided with the outflow through hole that flows out filtrate, flowing out the intercommunicating pore that is provided with between through hole and filter chamber the filtrate introducing outflow through hole of filter chamber, be provided with the injection through hole that injects mud in the center of filter chamber, protruding particle along filter press mud inject through hole outwards in the shape of a spiral the shape radiation evenly distribute.
Mud injects filter press with rotation mode under the effect of high-pressure pump, the projection particle injects outwards shape radiation profiles in the shape of a spiral of through hole along filter press mud, the mud that enters filter chamber can be flowed along the helical form " passage " of protruding micelle, reduced the resistance of protruding micelle, increased and injected the flowability of mud in filter chamber, thereby more effectively guaranteed the uniformity of mud in filter plate, " plate bursting " phenomenon when effectively having prevented high pressure.
As improvement, filter plate is that 15% polypropylene glass composite reinforcing material one-shot forming forms.
Filter plate selects for use the composite reinforcing material one-shot forming of 15% polypropylene glass to make, and filter plate rigidity and toughness are all better, can reach hard and soft balance, satisfy the demand of production status.
As further improvement, also be provided with the support column that flushes with the filter plate positive and negative in the bottom surface of filter chamber, can effectively prevent the distortion of filter plate when filter press is exerted pressure to filter plate.

Fig. 3 is the A-A cross-sectional schematic of Fig. 2.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of filter plate of plate and frame filter press, filter plate are that 15% polypropylene glass composite reinforcing material one-shot forming forms.Be provided with the filter chamber 1 of ccontaining mud at the tow sides of filter plate, be densely covered with protruding particle 2, be provided with the injection through hole 3 that injects mud in the center of filter chamber 1, on filter plate, also be provided with the cavity 7 that is used for the barrier film extruding in the bottom surface of filter chamber 1.The injection through hole 3 that protruding particle 2 on filter chamber 1 bottom surface injects along filter press mud outwards in the shape of a spiral the shape radiation evenly distribute.Four angle positions at the periphery filter plate of filter chamber 1 are respectively equipped with the outflow through hole 4 that flows out filtrate, flow out through hole 4 and 1 of filter chamber is provided with three intercommunicating pores 5 that the filtrate introducing of filter chamber 1 flowed out through hole 4 at each.Also evenly be provided with four support columns 6 that flush with the filter plate positive and negative in the bottom surface of filter chamber 1.
Claims (3)
1, the filter plate of plate and frame filter press, be provided with the filter chamber of ccontaining mud at the tow sides of filter plate, be densely covered with protruding particle in the bottom surface of filter chamber, periphery at filter chamber is provided with the outflow through hole that flows out filtrate, flowing out the intercommunicating pore that is provided with between through hole and filter chamber the filtrate introducing outflow through hole of filter chamber, be provided with the injection through hole that injects mud in the center of filter chamber, it is characterized in that: described protruding particle along filter press mud inject through hole outwards in the shape of a spiral the shape radiation evenly distribute.
