Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in Figure 1, High water cut cleaned coal dehydration ultra-high pressure piston type variable capacity pressure filter after this utility model one coal slime flotation, it includes oil cylinder 7, oil cylinder seat 6, girder 3, pressure plare 5, thrust plate 2, and is located at the parts such as some filter frames 4 between pressure plare 5 and thrust plate 2.
As it is shown on figure 3, the front and back of filter frame 4 are respectively provided on two sides with push plate 17, bearing plate 11;On same circumference, some Packing springs 13 it are provided with between push plate 17 and bearing plate 11;Bearing plate 11 is fixing with filter plate installing plate 14 to be connected;Fixing filter plate 12 is fixing with filter plate installing plate 14 to be connected;Fixing filter plate 12 is uniformly distributed on same circumference and is installed with four piston shaft 15;Eject that filter plate 18 and four piston shaft 15 are fixing to be connected;At fixing filter plate 12 with eject and be provided with four ejector springs 16 (depicting laterally zygomorphic two ejector springs 16 in Fig. 3) between filter plate 18 on same circumference.
As in figure 2 it is shown, filter frame assembly is provided with ear shoulder 9, running roller 10, thus filter frame may be mounted on girder 3.
Work process includes: pre-pressing stage, charging stage, squeezing stage, four main process of pulling plate unloading stage.
Pre-pressing stage: start Hydraulic Station 8 and drive oil cylinder 7 that filter frame 4 is pushed to thrust plate 2 side, make each filter frame 4 closely be adjacent to;As it is shown on figure 3, filter frame 4 outer ring can be extruded shortening at pressure-bearing sheet frame and the Packing spring 13 pushed between sheet frame under oil cylinder working-pressure effect;The elastic range design load of Packing spring 13 can be controlled in 10~30mm.
Charging stage: coal slurry is squeezed in filter frame 4 through entering mud pipe 1 by plunger displacement pump, moisture oozes through filter cloth 19, coal slurry is gradually filled with filter frame 4, concentration gradually rises, meanwhile, the coal slurry of high concentration produces pressure gradually, and promotion ejects filter plate 18 and moves to the inside, ejector spring 16 is compressed, absorption portion potential energy;After ejector spring 16 compression section stroke, fitting with filter plate installing plate 14 in filter plate 18 back that ejects connected together with it, no longer retreats.
The squeezing stage: be again started up oil cylinder 7, filter frame 4 is pushed to thrust plate 2 direction, under high pressure effect, Packing spring 13 is extruded further, as shown in Figure 3, Figure 4, A=65~80mm when the filter chamber degree of depth is from charging is extruded to about B=30~50mm, and pressure can be increased to 5~9MPa, and coal slurry is extruded as briquette (filter cake);Briquette moisture content is down to about 10%~8%.
In the pulling plate unloading stage: oil cylinder 7 return, the strength release of Packing spring 13, filter frame 4 recovers to free state, by the drawing-plate mechanism that equipment carries, is pulled open successively by filter plate;Pulling open because ejector spring 16 potential energy discharges in process, promotion ejects filter plate 18 and shifts, and this strength can overcome the adhesion between briquette and framework.Such briquette is natural to be separated with framework, deviates from filter frame, completes discharging.
The main technical point of ultra-high pressure piston type variable capacity pressure filter of the present utility model is as follows:
1, big volume, decrement is up to 15%~20%;
2, high pressure, squeeze pressure is up to 5~9MPa;
3, novel auxiliary discharge way (spring dump), can realize filter cake and automatically drop.
