Abstract
The invention relates to a filter, in particular to a vacuum tray type pressing filter. A filtering plate (2) of the vacuum tray type pressing filter is a disk formed by a plurality of sector plates (7); a set of pressing device (3) is arranged on each of two sides of each sector plate; each set of pressing device comprises a pressing plate (1), a hydraulic cylinder (5), a piston rod guide (6), a hydraulic cylinder base (8) and a connecting seat (10); the hydraulic cylinders are fixed on the hydraulic cylinder bases (8); the pressing plates are arranged on one sides of the hydraulic cylinders; the connecting seats (10) are arranged on side surfaces of the pressing plates; piston rods (9) of the hydraulic cylinders are fixedly connected with the pressing plates through the connecting seats; the piston rod guides are arranged between the hydraulic cylinders and the pressing plates. The pressing devices are correspondingly arranged on two sides of the sector plates of the filtering plate, so that the purpose that a filter cake on the rotary filtering plate is pressed and filtered is achieved, and the production efficiency is improved effectively.
Description
[technical field]
The present invention relates to a kind of filter, especially relate to a kind of vacuum disc type pressing filter.
[background technology]
Known, filter is mainly used in the filtering means dehydration of the concentrate of coal industry and coal slime, the concentrate in all kinds of mine, mine tailing and red mud, filter is mainly divided into vacuum disc type filter and filter press, vacuum filter is by the swabbing action of vavuum pump, filtration disc is made to become vacuum, atmospheric pressure is relied on to realize Separation of Solid and Liquid, its course of work is: the filtration disk of vacuum disc type filter rotates in the cell body filling with slip, when disc rotary enters slip, by the vacuum action in disk, inside and outside disk, mineralization pressure is poor, liquid in slip is pressed into disk and flows away, catching, solid particles is adsorbed on disc surfaces and forms filter cake, when disc rotary goes out slip, continue to vacuumize, filter cake is still adsorbed on disk, disk continues to rotate, vacuum stops, filter cake comes off, disk continues rotation and again enters slip, form a working cycles, vacuum disc type filter filter pressure mainly relies on vacuum action, poor with air mineralization pressure, because the general pressure of a variety of causes only has 0.04 ~ 0.06Mpa, limit filter pressure is also only a standard atmospheric pressure and 0.1MPa, so its filter pressure is too little, when filtering superfine material, the liquid holdup of filter cake is higher, and although filter press pressure is large, it can not continuous operation, and production efficiency is low, and complex structure.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of vacuum disc type pressing filter, arrange pressue device by the equal correspondence in the both sides of the fanning strip at filtering table, the filter cake achieved on the filtering table rotated carries out the object of pressure filtration, effectively improves production efficiency.
In order to realize described goal of the invention, the present invention adopts following technical scheme:
A kind of vacuum disc type pressing filter, comprise filter, the filtering table of described filter consists of disk by polylith fanning strip, corresponding respectively in the both sides of every block fanning strip one group of pressue device is set, often organize pressue device and include pressing plate, hydraulic cylinder, piston rod guiding, hydraulic cylinder base and Connection Block, described hydraulic cylinder is fixed on hydraulic cylinder base, pressing plate is provided with in hydraulic cylinder side, pressing plate side is provided with Connection Block, the piston rod of described hydraulic cylinder is fixedly connected with by Connection Block with pressing plate, is provided with piston rod guiding between hydraulic cylinder and pressing plate.
Described vacuum disc type pressing filter, described piston rod is directed to two " L " shape connecting rods be articulated and connected, and wherein the cylinder body of a connecting rod and hydraulic cylinder is articulated and connected, and the Connection Block of an other connecting rod and pressing plate side is articulated and connected.
Described vacuum disc type pressing filter, described hydraulic cylinder base is fixedly installed on filter main shaft.
Owing to have employed technique scheme, the present invention has following beneficial effect:
Vacuum disc type pressing filter of the present invention, by the equal correspondence in the both sides of the fanning strip at filtering table 2, pressue device is set, the filter cake achieved on the filtering table rotated carries out the object of vacuum filtration and pressure filtration simultaneously, effectively improve production efficiency, and structure is simple.

[detailed description of the invention]
By explanation the present invention that the following examples can be detailed, disclose object of the present invention and be intended to protect all technological improvements in the scope of the invention.
Vacuum disc type pressing filter by reference to the accompanying drawings described in 1-2, comprise filter, the filtering table 2 of described filter consists of disk by polylith fanning strip 7, corresponding respectively in the both sides of every block fanning strip 7 one group of pressue device 3 is set, often organize pressue device 3 and include pressing plate 1, hydraulic cylinder 5, piston rod guiding 6, hydraulic cylinder base 8 and Connection Block 10, described hydraulic cylinder 5 is fixed on hydraulic cylinder base 8; Described hydraulic cylinder base 8 is fixedly installed on filter main shaft 4; Be provided with pressing plate 1 in hydraulic cylinder 5 side, pressing plate 1 side is provided with Connection Block 10, the piston rod 9 of described hydraulic cylinder 5 is fixedly connected with by Connection Block 10 with pressing plate 1, is provided with piston rod and leads 6 between hydraulic cylinder 5 and pressing plate 1; Described piston rod guiding 6 is two " L " shape connecting rods be articulated and connected, and wherein the cylinder body of a connecting rod and hydraulic cylinder 5 is articulated and connected, and the Connection Block 10 of an other connecting rod and pressing plate 1 side is articulated and connected.
Implement vacuum disc type pressing filter of the present invention, in use, by the both sides being arranged on every block fanning strip 7 corresponding for pressue device, vacuum disc type filter operationally, hydraulic cylinder 5 is connected with the Hydraulic Station being arranged on filter outside, being fixed on hydraulic cylinder base 8 on filter main shaft 4 along with fanning strip 7 rotates together, be fixed on the hydraulic cylinder 5 on hydraulic cylinder base 8, the piston rod be hinged on hydraulic cylinder 5 cylinder body and Connection Block 10 leads and 6 to rotate along with hydraulic cylinder base 8, when the filtering table 2 of filter rotates material, the hydraulic cylinder 5 of fanning strip 7 both sides starts action, as shown in Figure 2, dotted portion shows: the piston rod 9 of hydraulic cylinder 5 drives the connecting rod of piston rod guiding 6 pressing plate 1 and fanning strip 7 plate face to be extruded mutually, reach the object of the material of absorption on fanning strip 7 being carried out to press filtration, now pressue device 3 is along with filtering table 2 synchronous rotary, when fanning strip 7 rotates to Tuo Liao district, pressue device 3 stops action, no longer fanning strip 7 is extruded, the present invention uses hydraulic cylinder 5 to pressurize, can be replaced cylinder pressurization, and be connected with cylinder at the outer setting pneumatic means of filter, by the equal correspondence in both sides at filter disc 2 fanning strip 7, pressue device is set, achieve the mode of simultaneously carrying out vacuum filtration and pressure filtration on filter, production efficiency is improved greatly, and achieves the object of filter press continuous operation.
