Description
Technical field
The present invention relates to a kind of centrifuge apparatus, the remaining filter cake scavenge unit of a kind of horizontal type scraper centrifuger, belongs to horizontal type scraper centrifuger technical field specifically.
Background technology
At present, the automatic centrifuge discharging generally used is the mode adopting scraper discharging substantially, and be by rotary drum under lower-speed state, the solid bed of material scraping after centrifugation in rotary drum, slowly near rotatory drum wall, is progressively got off by scraper.Owing to being that scraper and rotatory drum wall exist relative motion, unrestrictedly close to rotatory drum wall, can not consider safety, the remaining bed of material that generally can there is about 5mm cannot be peeled off automatically, artificial removing can only be relied on, not only reduce the organic efficiency of every batch materials.The remaining filter cake scavenge unit roller of original design does not have elastic mechanism, run into harder material or distance filter cloth nearer time can not automatically dodge, easily filter cloth is damaged.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of horizontal type scraper centrifuger remaining filter cake scavenge unit, can be used in the remaining filter cake removed on bulging wall, can avoid damaging filter cloth simultaneously, and roller can be made to greatest extent close to filter cloth, what filter cake was removed is more thorough, improves service life and result of use.
According to technical scheme provided by the invention, the remaining filter cake scavenge unit of a kind of horizontal type scraper centrifuger comprises driving oil cylinder, drives on the telescopic shaft of oil cylinder and passes through flat key connecting bushing, it is characterized in that: be provided with torsionspring between the telescopic shaft of axle sleeve and driving oil cylinder; Axle sleeve upper end connects rolling wheel support by intermediate support, is rotationally connected roller shaft in rolling wheel support by roller bearing, and roller shaft two ends connect roller; Be provided with the first gas circuit in the telescopic shaft of described driving oil cylinder, the first gas circuit outlet side connects the second tracheae, and a nozzle is fixed at rolling wheel support two ends respectively, and the second tracheae connects the nozzle at rolling wheel support two ends respectively by the first tracheae.
Further, drive the telescopic shaft outer end of oil cylinder to connect gland, torsionspring is pressed between axle sleeve and the telescopic shaft driving oil cylinder by gland, and axle sleeve outer end connects end cap, and gland is pressed on the telescopic shaft outer end driving oil cylinder by end cap.
Further, be provided with sealing ring between roller shaft and rolling wheel support, sealing ring is positioned at roller bearing inner ring.
Further, be provided with the second gas circuit in roller shaft, the second gas circuit inlet end is connected with the second tracheae, and the second gas circuit outlet side is connected with pore.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, can be used in the remaining filter cake removed on bulging wall, torsionspring is provided with in axle sleeve, certain pretightning force is imposed by roller compression on rotatory drum wall during installation, roller operationally has certain resilience, can avoid damaging filter cloth, and roller can be made to greatest extent close to filter cloth, what filter cake was removed is more thorough, improves service life and result of use.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises driving oil cylinder 1, drives on the telescopic shaft of oil cylinder 1 and passes through flat key 3 connecting bushing 2, be provided with torsionspring 4 between the telescopic shaft of axle sleeve 2 and driving oil cylinder 1.
The telescopic shaft outer end of described driving oil cylinder 1 connects gland 5, and torsionspring 4 is pressed between axle sleeve 2 and the telescopic shaft driving oil cylinder 1 by gland 5.Described axle sleeve 2 outer end connects end cap 6, and gland 5 is pressed on the telescopic shaft outer end driving oil cylinder 1 by end cap 6.
Axle sleeve 2 upper end connects rolling wheel support 8 by intermediate support 7, is rotationally connected roller shaft 9 in rolling wheel support 8 by roller bearing 11, and roller shaft 9 two ends connect roller 12.
Be provided with sealing ring 10 between described roller shaft 9 and rolling wheel support 8, sealing ring 10 is positioned at roller bearing 11 inner ring.
Be provided with the first gas circuit 16, first gas circuit 16 outlet side in the telescopic shaft of described driving oil cylinder 1 and connect the second tracheae 15.A nozzle 13, second tracheae 15 connects rolling wheel support 8 two ends respectively nozzle 13 by the first tracheae 14 is fixed at rolling wheel support 8 two ends respectively.
Be provided with the second gas circuit 17, second gas circuit 17 inlet end in described roller shaft 9 to be connected with the second tracheae 15, the second gas circuit 17 outlet side is connected with pore 18.
When the present invention works, oil cylinder is driven to drive rolling wheel support, roller shaft and roller near rotatory drum wall, remaining cake layer on rotatory drum wall is ground and peels off, first gas circuit passes into gases at high pressure simultaneously, gases at high pressure are sprayed from the nozzle of the first tracheae, makes to stick in the material on drum inner wall and come off further under the purging of gas.In addition, the gas in the second gas circuit directly purges in the labyrinth seal position at two ends from the pore ejection at two ends, forms certain pressure and guarantees that outside liquid and corrosive gas do not cause corrosion to bearing.In the course of the work, when roller runs into harder material or other rigid object, resilience can dodge under the effect of torsionspring, avoid causing damage to filter cloth.
