Fig. 3 is the structural schematic diagram that preferred embodiments filter select.
Specific embodiment
With reference to Fig. 1 Fig. 2 Fig. 3, a kind of piston type filter press, including horizontal positioned both ends open at cylindrical filtration cartridges 1,
The both ends of filter cylinder are fixedly connected on framework 5, and 1 side wall of filter cylinder is equipped with multiple perforative filter openings 11, and the tube wall of filter opening 11 is equipped with spiral shell
Line, the structure such as spiral shell select for filtering select 12 is similar, and side wall is equipped with screw thread, therefore filter select 12 can be rotated by screw thread and be threaded into filter opening 11
In, the centre of filter select 12 was equipped with a perforative micropore 14, and micropore 14 is the equal of the effect of strainer, plays the pressure of separation of solid and liquid
Filter effect filters and is additionally provided with sealing ring 13 on select 12, and in the state of passing through screw threads for fastening, sealing ring 13 plays the work of sealing
With；
Top position among filter cylinder 1 has feed pipe 2, and valve 21 is connected on feed pipe, when valve 21 is closed, charging
Pipe 2 can be closed, and the other end of feed pipe 2 is connected to hydraulic station.
One end of filter cylinder 1 is equipped with secondary piston 31, and secondary piston 31 is connected with hydraulic cylinder 32, and the other end of filter cylinder is equipped with rear piston
41, rear piston 41 is connected with hydraulic cylinder 42, and hydraulic cylinder 32 and hydraulic cylinder 42 are respectively connected with fluid pressure line, valve and hydraulic power
Source, the inner wall that hydraulic cylinder 32 can drive secondary piston 31 to be tightly attached to filter cylinder 1 carry out the displacement of horizontal direction, and hydraulic cylinder 42 can drive
The inner wall that dynamic secondary piston 41 is tightly attached to filter cylinder 1 carries out the displacement of horizontal direction, and the rear end of hydraulic cylinder 32 and hydraulic cylinder 42 is and structure
Frame 1 is fixedly connected.
The lower section of filter cylinder 1 is equipped with liquid dish 51, and for collecting the filtrate after filters pressing, the middle position of liquid dish 51 is connected with
Flexible duct 52, framework 1 are equipped with sliding slot 54 at the position for corresponding to 51 two sides of liquid dish, and the two sides of liquid dish 51 are equipped with convex block
55, convex block 55 can be incorporated into sliding slot 54, and realize that liquid dish 51 can be from the lower section from filter cylinder 1 under the limitation of sliding slot 54
It skids off, convenient for being maintained or replaced to filter select 12, in the rear side of filter cylinder 1, i.e., side is equipped at the rear corresponding position of piston 31
Receiver 53, for collecting the filter cake after filters pressing, receiver 53 is tilted to the side of framework 1, convenient for collecting in the side of framework 1
Filter cake after filters pressing.
In the work of this piston type filter press, first, in accordance with filters pressing requirement and the property of material, installs and correspond on filter cylinder 1
Filter select 12；
In original state, rear piston 41 is under the action of hydraulic cylinder 42, the rear end in filter cylinder 1, and by the rear end seal of filter cylinder 1
It closes, secondary piston 31 is under the action of hydraulic cylinder 31, the front end in filter cylinder 1, and the front end of filter cylinder 1 is closed, at this point, filter cylinder 1
Inside has maximum capacity；
Hereafter, valve 21 is opened, and under the action of hydraulic station, material enters to the inside of filter cylinder 1 by feed pipe 2, when filter cylinder 1
When inside is full of material 2, portion filtrate flows out from the micropore of filter select 12, under the action of hydraulic station, continues to stress on material,
