Cylinder piston rod tension-type sealing filter plate device
technical field:
The utility model belongs to filter plant field, and what be specifically related to is a kind of cylinder piston rod tension-type sealing filter plate device.
background technology:
Current traditional horizontal pressure filter generally holds out against part, running part, pressure strip by twin beams part, oil cylinder and divides, the compositions such as filter plate part, thrust plate part, oil cylinder, twin beams or four beams, thrust plate form main machine frame, and pressure strip straddles on two girders, and is connected with the piston rod of oil cylinder; Cylinder piston rod heads on pressure strip reach press seal filter plate.This structural disadvantages is that oil cylinder, twin beams or four beams, thrust plate form main machine frame, because crossbeam is that assembly welding forms, internal stress is unbalanced, when oil cylinder holds out against pressure strip and filter plate, oil cylinder retaining point is that one end is fixed on crossbeam end, the other end is fixed on retaining plate, crossbeam stretches when oil cylinder holds out against pressure strip, and the tensile strength of every crossbeam is different, crossbeam elongatedness is also unequal, cause framework modification, diagonal angle not, filter plate inplane pressure sealing force is unbalanced, while there is pan feeding between filter plate the outside material spray of slip and filter plate spoilage high.
utility model content:
In order to overcome the deficiency in background technology, the utility model provides a kind of cylinder piston rod tension-type sealing filter plate device.Solved and take retaining plate as fulcrum, a difficult problem for pan feeding, diaphragm pressing, blowing are dry, the filter plate expansive force in Washing of Filter Cake process does not stretch girder.
The utility model solves the technical scheme that its technical problem adopts: this cylinder piston rod tension-type sealing filter plate device, is comprised of oil cylinder, fixture, retaining plate, piston rod, girder, pressure strip, semiaxis, piston rod earrings, fixed mount.Described girder is rectangular frame structure, and erection of main beam is on fixed mount and retaining plate, girder is provided with pressure strip, pressure strip both sides are provided with oil cylinder, in oil cylinder, be provided with piston rod, the piston rod earrings of the piston rod other end is connected with the semiaxis of pressure strip both sides, and oil cylinder is fixed on retaining plate by fixed mount.
Described oil cylinder is at least provided with two.
Described fixed mount is square flange or oil cylinder gudgeon.
The beneficial effects of the utility model are: integrate mechanical, electrical, liquid, be applicable to the isolated by filtration of various suspension, mixed liquor, each needs the field of Separation of Solid and Liquid to be widely used in mineral processing, chemical industry, papermaking, coal, metallurgy, medicine, food and environmental protection etc.Cylinder rod chamber drives pressure strip to close up at the effect lower piston rod of oil pressure, all filter plates of pressure strip press seal.This cylinder piston rod tension-type sealing filter plate device is that the tensile force of crossbeam is changed on cylinder piston rod, and crossbeam only bears the orientation of certain load and pressure strip, filter plate back and forth movement.Pressure strip, filter plate are subject to pressure even under pressure, and frame structure is reliable and stable, simple in structure, operates steadily, and have improved equipment service life, have reduced use cost.Simple and reasonable, the novelty that is skillfully constructed, is easy to large-scale promotion application.
accompanying drawing explanation:
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
the specific embodiment:
With reference to each figure, this cylinder piston rod tension-type sealing filter plate device, by oil cylinder 1, fixture 2, retaining plate 3, piston rod 4, girder 5, pressure strip 6, semiaxis, piston rod earrings 7, fixed mount 8, formed, described girder 5 is rectangular frame structure, and be arranged on fixed mount 3 and retaining plate 8, girder 5 is provided with pressure strip 6, pressure strip 6 both sides are provided with oil cylinder 1, in oil cylinder 1, be provided with piston rod 4, the piston rod earrings 7 of piston rod 4 other ends is connected with the semiaxis of pressure strip 6 both sides, and oil cylinder 1 is fixed on retaining plate 3 by fixed mount 2.Described oil cylinder 1 is at least provided with two.Described fixed mount 2 is square flange or oil cylinder gudgeon.When filter press is started working, rod chamber piston rod 4 retractions under pressure drive pressure strip 6 to compress and sealing filter plate.Integrate mechanical, electrical, liquid, be applicable to the isolated by filtration of various suspension, mixed liquor, each needs the field of Separation of Solid and Liquid to be widely used in mineral processing, chemical industry, papermaking, coal, metallurgy, medicine, food and environmental protection etc.Pressure strip 6 is subject to pressure even, improves stability, the reliability, simple in structure of frame mechanism, operates steadily, and has improved equipment service life.Simple and reasonable, the novelty that is skillfully constructed, is easy to large-scale promotion application.
