Problems solved by technology

It has been proved by production and use that the disadvantages of this equipment are: (1) the support is a two-point support, that is, two supports, and it is difficult to install, maintain and replace; (2) the manufacturing precision and lubrication conditions of the planetary differential are relatively high, and the structure Complex and high cost; (3) The conical screen basket limits the increase in output and separation effect; (4) The feed pipe takes up a lot of space, which brings inconvenience to the maintenance and replacement of the screen basket and vortex tube; (5) Lubrication The system is complex, and there is a problem of lubricant leakage; (6) The whole equipment is expensive, which limits its popularization and use

Abstract

The invention relates to a single supporting point horizontal helical-conveyer centrifugal, which dehydrates grains with the size 0-3mm, water content around 50% coal mud with centrifugal treatment. It uses a generator to drive dehydrating screening basket and helical discharger through two sets of syntactic wheel and belt, ensuring the stable rotation difference, realizing dehydration and discharge. It is simpler than planetary gear differential, free from lubrication for the syntactic belt, reliable in running, two embedded drive shafts, outside hollow shaft of the screening basket supported by two rolling bearings, using grease for lubrication, self lubricating bearing between the hollow shafts of the helical discharge and sorting basket, with the overall rotating system supported by a base for the convenience of installation and maintenance.

Description

technical field [0001] The invention relates to a single fulcrum horizontal spiral discharge filter centrifuge, which belongs to the dehydration equipment of a coal preparation plant. It is suitable for centrifugal filtration and dehydration of coal slime water with a particle size of 0-3mm and a water content of about 50%. Background technique [0002] Fine-grained coal slime dehydration is an operation link with large investment, relatively high energy consumption and operating costs in coal preparation plants, but it is also an indispensable process link in modern coal preparation plants. Due to the low cost of centrifugal filtration dehydration, large unit processing capacity, low product moisture, relatively simple and reliable dehydration system and small footprint, there are many researches and developments on filter-type slime centrifuges abroad. At present, the more advanced equipment for centrifugal filtration and dehydration of fine coal slime is a horizontal mac...
