Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the present invention is described in further details.
As depicted in figs. 1 and 2, efficient filter press of the present invention, comprises Control Component, bracket component and is installed on two filter plate assemblies, more than one group the holding down assembly on bracket component; Holding down assembly in the present invention comprises two oil cylinders 1 and is arranged in the piston rod 2 of each oil cylinder 1, two oil cylinders 1 are all fixed on oil cylinder Connection Block 5 with hinging manner by oil cylinder contiguous block 13, two piston rods 2 are fixed on piston rod Connection Block 3 by hinging manner, oil cylinder Connection Block 5 is positioned at one end of bracket component, and piston rod Connection Block 3 is between two groups of filter plate assemblies. Fixing of this mode, can allow the work of hold down gag slightly rotate more flexibly and facilitate adjusted in concert, in the time that disposable filter plate compresses or pulls open, can allow tailpiece of the piston rod synchronously more flexible, avoid oil cylinder 1 and piston rod to sprain bad, be not easy to damage whole hydraulic compressing device. In the present embodiment, holding down assembly is two groups, and Shang Xia 10 two ends to lay respectively at brace summer. Be appreciated that the needs according to actual thrust, also can design holding down assembly of greater number. Closed up and compressed and pull open cake discharge work by multiple oil cylinders 1, oil cylinder cylinder diameter is less than single cylinder, and hydraulic compression power distributes more even, is conducive to large-scale filter plate frame sealing. Oil cylinder is connected by hinge axis mode with oil cylinder Connection Block, and piston rod is also connected by hinge axis mode with piston rod Connection Block.
Each filter plate assembly comprises thrust plate 6, pressure strip 8 and the some filter plates that are arranged in order 7, and filter plate 7 is fixed on filter plate support 11. Between adjacent filter plate 7, be provided with filter cloth 16 and be connected chain; pressure strip 8 is positioned at end close another filter plate assembly of filter plate assembly; coordinate with piston rod 2 and piston rod Connection Block 3, realize and close up or pull open, and thrust plate 6 is positioned at another end of filter plate assembly. On thrust plate 6, offer charging aperture 12, air inlet 9, exhaust outlet 14 and discharge outlet 15.
Like this, two thrust plates 6 are positioned at complete machine two ends, two pressure strips 8 are positioned at complete machine middle part, the integrated moving along with the movement of piston rod Connection Block 3, two filter plate assemblies can disposablely pull open cake discharge and close up compression, the piston rod thrust and the pulling force that take full advantage of hydraulic means, energy consumption utilization ratio is high. The thrust plate 6 at two ends is provided with charging aperture 12 and can all can takes turns and flow to slurry press filtration in two, has realized the work of unit continuous filter press, and filter plate 7 can disposablely pull open cake discharge and close up compression.
In the present embodiment, bracket component comprises two brace summers that are arranged symmetrically 10, and filter plate assembly is all installed on brace summer 10 with holding down assembly, and two filter plate assemblies are arranged along the length direction of brace summer 10. Two pressure strips 8 are directly fixed on oil cylinder Connection Block 5, and two thrust plates 6 are directly installed on the two ends of brace summer 10. Further, below brace summer 10, be provided with foot rest 4. Be positioned at the outside of brace summer 10 owing to holding down assembly, saved this device in filter press length space, structure is compacter.
In the present embodiment, Control Component can adopt the form of PLC switch board. On bracket component, be fixed with gravity sensor 17, gather real-time weight signal to PLC switch board, carry out automation control by PLC program.
When work, piston rod 2 has been realized moving back and forth of pressure strip 8 and piston rod Connection Block 3 back and forth stretching of 1 li of oil cylinder, along with moving back and forth of pressure strip 8, filter plate 7 in two groups of filter plate assemblies is closed up respectively compresses and pulls open cake discharge, filter plate 7 is closed up after compression, can be by the charging aperture 12 charging press filtration work on thrust plate 6. After press filtration completes, pull open cake discharge, the filter plate 7 in another group filter plate assembly is closed up to compression, can carry out the charging press filtration work of this group filter plate 7 after having compressed, having realized unit can continuous filter press work.
Below be only the preferred embodiment of the present invention, protection scope of the present invention is also not only confined to above-described embodiment, and all technical schemes belonging under thinking of the present invention all belong to protection scope of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
