Abstract
The utility model relates to a pressure filter which is a solid-liquid separation device using oil cylinders pressure to press. The utility model can obviously reduce liquid content in a filter cake (5), and has the technical proposal that an oil cylinder (1) is used for pressurizing to make an elastic rubber pad (4) between filter plates (3) compressed after material adding of a system, the filter cake (5) becomes thin, and remnant liquid in the filter cake (5) is extruded. The pressure filter using oil cylinders pressure to press is used for solid-liquid separation fields.
Description
The utility model is a kind of filter press that utilizes oil cylinder pressurization squeezing, and it is a kind of solid-liquid separating equipment.
The utility model filter press is different with present diaphragm filter press, diaphragm filter press is after pan feeding pumps into the material end, and filter cake is pushed in extruding with gases at high pressure (or liquid) thereby to barrier film, and the liquid in the filter cake is discharged, easily cause material spray, barrier film cost height during the extruding of diaphragm filter press barrier film.And the utility model is after pan feeding pumps into the material end, thereby utilizes the resilient rubbber cushion between strong filter plate of oil cylinder pressurization and the filter plate to be compressed the extruding filter cake.
The purpose of this utility model just provides a kind of equipment that can significantly reduce content liquid in the filter cake.
With reference to Fig. 1, Fig. 1 is the outline drawing of the utility model filter press, and it is the frame structure that is made of thrust plate (1), girder (4) and oil cylinder (7).Handle (3) on the filter plate (2) rides on the guide pass of girder (4), between filter plate (2) and the filter plate (2) filter cloth, resilient rubbber cushion are arranged, pressure strip (5) is linked together with the piston rod of oil cylinder (7), roller on the pressure strip (5) can move along the guide pass on the girder (4), (6) be drawing-plate mechanism, (8) be the switch board of filter press, (9) are hydraulic power units.When the utility model utilizes the filter press work of oil cylinder pressurization squeezing, piston rod on the oil cylinder (7) stretches out and drives pressure strip (5), filter plate (2) is to left movement, filter plate (2) is pressed between pressure strip (5) and the thrust plate (1), resilient rubbber cushion between the filter plate (2) and filter plate (2) form certain sealing load, pan feeding begins, along with the prolongation filter cake of time is more long-pending the more, pan feeding finishes, oil cylinder this moment (7) the pressurization squeezing regular hour is extruded the liquid in the filter cake, after oil cylinder (7) pressurization squeezing finishes, piston rod on the oil cylinder (7) drives pressure strip (5) and moves right, at this moment drawing-plate mechanism (6) moves back and forth, filter plate (2) is drawn back in succession, and filter cake relies on the deadweight discharging, and so far a working cycles finishes.
The utility model is compared with diaphragm filter press, can significantly reduce content liquid in the filter cake, and equipment operating cost is low.
With reference to Fig. 2, Fig. 2 is the fundamental diagram that utilizes the filter press of oil cylinder pressurization squeezing, during filter press work, oil cylinder (1) promotes pressure strip (2) and is moved to the left, filter plate (3) is pressed between pressure strip (2) and the thrust plate (7), and the resilient rubbber cushion (4) between filter plate (3) and the filter plate (3) is subjected to the certain thrust P of oil cylinder (1)
1Form the sealing filter chamber, the pan feeding pump is squeezed into ore pulp in the filter chamber with certain pressure then, ore pulp carries out Separation of Solid and Liquid by the pressure of pan feeding pump through filter cloth (6) filtration, liquid is discharged from outside the filter chamber, along with the prolongation of time, filter cake (5) is more long-pending the more, until all being full of filter chamber, pan feeding finishes, and oil cylinder this moment (1) is with certain pressure P
2(P
2＞P
1) pressurize, the resilient rubbber cushion (4) between filter plate (3) and the filter plate (3) is at oil cylinder working-pressure P
2Be compressed certain thickness under the effect, filter cake (5) is squeezed and attenuation simultaneously, thereby make and remain in the intergranular liquid of filter cake (5) and extruded once more, further reduce the content of liquid in the filter cake (5), unclamp pressure strip (2) then and draw back filter plate (3) and carry out discharging, so far filter press is finished a working cycles.
Claims (1)
1, a kind of filter press that utilizes oil cylinder pressurization squeezing, it is made up of oil cylinder (1), pressure strip (2), filter plate (3), resilient rubbber cushion (4), filter cloth (6), thrust plate (7) etc., it is characterized in that containing resilient rubbber cushion (4) between filter plate (3) and the filter plate (3).
