Description
Technical field
The present invention relates to centrifuge, refer more particularly to the scraper in the filter bag type centrifuge.
Background technology
Along with developing by leaps and bounds of chemical industry, pharmaceutical industry, in process, need large-scale centrifuge to satisfy the demand of production capacity to the deep processing of intermediate.As everybody knows, super-magnum centrifuge is hanging material in the process of unloading with suspender after to material dewatering; because being the material of filter cake shape hardens on filter bag; the bulk density of material is quite high, takes place to cause breaking of filter bag owing to lifting by crane by force through regular meeting, has shortened the service life of filter bag greatly.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of and make that filter cake is loose, the scraper in the filter bag type centrifuge of the bulk density that reduces material.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the scraper in the filter bag type centrifuge, comprise: scraper and scrape tool rest, scrape tool rest and be provided with supported box, be movably set with rotation nut, driving shaft and worm screw in the supported box, the scraper screw mandrel that is located in the supported box is connected with the rotation nut by screw thread, rotation nut arranged outside has driven gear, one end of driving shaft is provided with first handwheel, and the other end of driving shaft is provided with the driven wheel that is meshed with driven gear; Also be provided with gathering sill on the described scraper screw mandrel, the feather key that is slidingly arranged in the gathering sill fixes with the rotary sleeve that is sleeved on the scraper screw mandrel, rotary sleeve is bearing in following the covering that is fixed on the supported box, also be provided with worm gear on the rotary sleeve, this worm gear is meshed with the gear of worm screw one end end, and the other end of worm screw is provided with second handwheel; Described scraper is arranged on the bottom of scraper screw mandrel.
Also be provided with axle bush between described lower cover and the rotary sleeve.
Also be set with the sleeve nut on the lower end of described rotary sleeve, the sleeve nut is connected with the protective sleeve that is sleeved on scraper screw mandrel bottom.
Further technical problem to be solved by this invention is: a kind of slewing area that limits scraper is provided, prevents the scraper in its filter bag type centrifuge that scratches filter bag.
For solving above-mentioned further technical problem, the technical solution used in the present invention is: described supported box is provided with loam cake, described scraper screw mandrel is located in the loam cake, the top of scraper screw mandrel is provided with limited block, be provided with the forward and reverse spacing collar that is used to limit scraper screw mandrel slewing area in the loam cake, also be equipped with the set lever that is used for the lock adjustment screw mandrel in the loam cake.
The invention has the beneficial effects as follows: super-magnum centrifuge is when discharging, can use will harden most of material on filter bag of scraper of the present invention to scrape and fall, significantly reduced the bulk density of material, and then with suspender material is hung and to draw off bowl, thereby avoided hanging by force and drawn the damage that filter bag is caused, the service life of having improved filter bag effectively.In addition, by the slewing area that forward and reverse spacing collar limits the scraper screw mandrel is set, making has enough safety clearances between the scraper that is arranged on scraper screw mandrel bottom and the filter bag, thereby has avoided the accidental injury of scraper to filter bag.
