Description
Technical field
The present invention relates to piston push centrifuge technical field, more particularly to a kind of piston push centrifuge anticorrosion antiwear to fill
Put.
Background technology
Piston push centrifuge belongs to the centrifuge of a kind of continuous feed, separation, discharging, and pusher disk and rotary drum are same during work
Step rotation, while pusher disk makees the back and forth movement of axial direction also relative to rotary drum;Suspension is entered by feed pipe through cloth tray to be turned
On the screen cloth of drum inner circle, liquid phase is thrown out of outside machine through screen cloth, and solid phase then is retained to form filter cake by screen cloth, and filter cake is by moving back and forth
Pusher disk release vertically rotary drum complete separation of solid and liquid.
The components such as the rotary drum of existing piston push centrifuge, pusher disk, screen cloth are made up of the stainless steel of metal material mostly
(Mohs' hardness 5.5), high rigidity is being separated and during severe corrosive material, such as quartz sand (Mohs' hardness 7), due to the hardness of material
More than the hardness of stainless steel and common metal, very hard material directly washed away under the action of the centrifugal force when feeding pusher disk and screen cloth,
Material is very big to screening media under the reciprocating motion of pusher disk, screen cloth premature failure under the severe friction of abrasive material;Another high temperature
Strong acid and high-concentration chlorine ion under environment is to rotary drum Inner stainless steel component seriously corrodeds, in separation strong acid and high rigidity material
When, the superposition destructive power of corrosion plus abrasion is huger, more accelerates the loss of hardware, and greatly influence machine uses the longevity
Life.
The content of the invention
The invention aims to overcome the shortcomings of above-mentioned machine in terms of wear-resisting and anti-corrosion, there is provided a kind of piston material pushing
Centrifuge anticorrosion antiwear device, effectively improves that machine is wear-resisting and antiseptic power is so as to extending the service life of machine.
Technical problem solved by the invention is realized using following technical scheme:A kind of piston push centrifuge anti-corrosion
Wear-resistant device, including feed pipe, cloth tray, toe dog, pusher disk, plastics lining, wear ring, ceramic screen, rotary drum etc., it is special
Levy and be：Wear-resistant plastic lining is provided with the flow-passing surface that feed pipe, cloth tray, toe dog, pusher disk etc. contact with material；
Wear ring is provided with the outer face of pusher disk；Wear-resistant ceramic screen cloth is equipped with rotary drum internal diameter.
The diameter parallel of above-mentioned wear ring is less than pusher disk in rotary shaft perpendicular to pusher disk plane, the diameter of wear ring
And be connected by screw bolts more than the diameter of cloth tray, wear ring on pusher disk to dismantle and to change, it is avoided that material to sieve
The direct impact of net and abrasion, avoid suspension from running material.
Above-mentioned wear-resistant ceramic screen cloth is made up of some rectangular ceramic filter discs, and some filtering rods are provided with every piece of ceramic filter disc
Seam and grating, large number of ceramic filter disc form a barrel-shaped screen drum along rotary drum inner circular arrangement, and grating is parallel with pusher direction.
Ceramic filter disc as described above by after ceramic raw material compression molding through high temperature sintering and as bar shaped sheet
Overall, Mohs' hardness 9 has high hardness wear-resisting corrosion-resistant characteristic, and the ceramic filter disc of bar shaped sheet is adapted to turn with all size
Drum inner circle fits.
The beneficial effects of the invention are as follows：Due to having added wear-resistant plastic lining and wear ring, high hard strong acid material is prevented
The impact and abrasion of material, the more notable extension of high rigidity and Anticorrosive Character of ceramic screen are contacted, slow down with hardware
The service life of screen cloth, will corrode plus the superposition destructive power of abrasion minimizes, and greatly extend the service life of machine.
The present invention is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structural representation of the invention applied in two-level piston material pushing centrifugal machine
Fig. 2 is the structural representation of wear ring
Fig. 3 is the mplifying structure schematic diagram of ceramic filter disc
Fig. 4 is the scheme of installation of ceramic screen
In figure：1 ceramic filter disc, 2 wear rings, 3 cloth trays, 4 feed pipes, 5 pusher disks, 6 toe dogs, 7 linings, 12 filtering rods seam,
13 gratings.
Embodiment
As shown in Figure 1：On the internal diameter of the feed pipe 4 of centrifuge, cloth tray 3, toe dog 6, pusher disk 5 and wear ring 2
Flow-passing surface on be usually coated plastic plate and set, form the nonmetallic release liner 7 of an anticorrosion antiwear；
Wear ring 2 is provided with the outer face of pusher disk, wear ring 2 is fixedly connected on pusher disk 5 to tear open using bolt
Unload and change, wear ring 2 is avoided that direct impact of the material to screen cloth and abrasion（Referring to Fig. 2）；
Wear-resistant ceramic screen cloth is equipped with rotary drum internal diameter, wear-resistant ceramic screen cloth is made up of some rectangular ceramic filter discs 1, such as Fig. 3
It is shown：It is provided with some filtering rods seam 12 and grating 13 on every piece of ceramic filter disc, grating 13 is parallel with pusher direction during installation, several
Measure numerous ceramic mesh sheet and form a barrel-shaped screen drum along rotary drum inner circular arrangement（Referring to Fig. 4）.Above-mentioned ceramic filter disc is by ceramic former
Through high temperature sintering and as the entirety of a bar shaped sheet after material compression molding, Mohs' hardness 9, there is high hardness wear-resisting corrosion-resistant
Characteristic.
High hard strong acid material passes through the flow-passing surfaces such as the feed pipe 4 for having added lining, cloth tray 3, pusher disk 5 and is thrown to during work
On wear ring 2, wear ring 2 slow down the impact wear of material and accelerate the rotation of material so as to the ceramic screen 1 on outer ring
