SU13522A1 - Filter press - Google Patents

Description

The proposed filter press consists of a press with a press filtering chamber filled and vertically emptied, one of the side walls of which is filled with hydraulic pressure, and the ceiling bottom walls of which, for loading and unloading purposes, may not be displaced in the horizontal direction. Hydraulic pressure is applied to the side wall of the extrusion vaier by using a piston moving in a stationary cylinder. The displacement of the ceiling and bottom walls is also accomplished by the force of hydraulic pressure, for which they are supplied with cylinders for fixed pistons. To facilitate unloading of the compressible material, as well as to increase the working area of the transverse filter walls, the last few are covered with wedge-shaped surfaces, between the bases of which are 1;

In FIG. 1 shows a vertical longitudinal section of the proposed filter press; FIG. 2nd horizontal section and FIG. 3rd vertical cross section.

The pressing chamber 1 is formed by fixed longitudinal walls 2 carrying the ribs 3, the transverse fixed wall 5 and the movable 6. The heads of the ribs 3 are covered with filtering surfaces 4 and 8. The resulting spacing of such a device serves to drain the pressed liquid. The transverse walls 5 and 6 are covered, leaving the drainage channels for wrung fluid, filter wedge-shaped surfaces 7. Ejector 9 arranged between the bases of the wedge surfaces 7, retractable but at the end of the pressing process into the pressing chamber 1. The transverse wall 6 of the nodes can be approached by hydraulic pressure to the opposite wall 5. For this purpose, serves a piston 10 moving inside a stationary cylinder 11 provided with tubes 12 for supplying a pressure fluid. Cylinder 11 is connected to counter-insert 13 for step 5 with spacer bolts 14 and 15. The ceiling wall 16 and the bottom wall 17 of the compressing chamber 1 are mounted motionless on horizontal guides 18 and 19, and each of them is provided with a cylinder 20

and 21 for pistons 22 and 23, the rods 24 and 25 of which are fixedly fixed in the head beam 26 connected to the cylinder 11. When the ceiling wall 16 is pulled out, the pressed material is loaded into the chamber 1, then the ceiling wall closes and the piston 10 begins to strain the pressure on wall 6. At the end of the pressing, the ceiling 16 and the bottom 17 of the wall retract simultaneously, hit the fist 39 and 40 tires connected to the movable wall 6, and pull back the transverse wall 6 and the piston 10. The pressed material is discharged downwards. This emptying movement is facilitated by the action of the ejection bars 9. The left ejectors 9 in FIG. 1 are controlled by the action of pulling springs 27 on the EI rods 28, the ends of which use the fingers 29. These latter are interconnected by a parallelogram lever system 30 and the drawbar swings 31, the tons of which 33, which is movably supported in the guides 32, carries the support 34, on which the nozzle 35, which is rigidly connected with the bottom wall, encounters at the appropriate moment. Control

The ejection bar 9 at the movable wall 6 of the pressing chamber is made in a similar way, with pressure presses n 36, the cams 37 of which are connected by a nailed lelogram rocking chair 39 loaded by the load 38 and swinging by the roller lever 55 incident on the surface of the bottom wall 17 when dragged last,

Subject patent a,

Filtrnress, characterized in that it is filled and emptied in the vertical direction by means of stationary, by hydraulic pressure force, in the horizontal direction the walls of the ceiling 16 and the bottom 17, the pressing chamber 1 is formed by fixed fixed walls 2 bearing the ribs 3 whose heads are covered filtering surfaces 4, transverse fixed wall b and movable hydraulic pressure using wall 6, which walls 5 and 6 are covered with wedge-shaped surfaces 7, between the bases of which are ejected drivers 9.
