The problem that the barrel was thrown away easily when using above -mentioned slag cylinder screen can effectively solve easy worn out cylinder screen barrel of slag and cylinder screen rotation can be practiced thrift the cost simultaneously greatly and improved slag screening efficiency.
Description
Technical field
The utility model relates to a kind of slag screening plant, belongs to material grading apparatus, is specifically related to a kind of slag drum sieve.
Background technology
Because in slag, the content of iron is much higher compared to iron ore, therefore the proportion of slag is also much bigger compared to ore, when using drum sieve to sieve, slag is larger to the impulsive force of drum sieve when charging, slag is harder than materials such as general ores simultaneously, therefore, the feed end ratio of drum sieve cylindrical shell is easier to be worn through, and means will change whole drum sieve cylindrical shell when feed end is worn out.When current drum sieve processes slag, also often can there is the situation because the too fast drum sieve cylindrical shell of drum speed is thrown out of.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of slag drum sieve, effectively can solve the problem that when the easy worn out drum sieve cylindrical shell of slag and drum sieve rotate, cylindrical shell is easily thrown out of, simultaneously can be greatly cost-saving and improve slag screening efficiency.
The utility model is achieved through the following technical solutions:
A kind of slag drum sieve, comprise column-shaped barrel, cylindrical shell both ends open is feed end and exhaust end respectively, it is characterized in that, described cylindrical shell is skewed, wherein the rational height of feed end is higher than the rational height of exhaust end, sieve aperture array is provided with between feed end and exhaust end, hopper is provided with bottom sieve aperture array, the inwall of feed end is provided with the sheath that can change, exhaust end is provided with deslagging bucket, the bottom outer wall of drum sieve feed end and exhaust end is equipped with the support roller supported, the top exterior walls of cylindrical shell feed end and exhaust end is equipped with pressing wheel device, the gear ring transmission mechanism that drum sieve cylindrical shell outside is provided with gear ring and drum sieve is rotated with the speed of 14 ~ 20 turns per minute.
Further, the angle of inclination of described drum sieve cylindrical shell is 5o ~ 8o.Be preferably 6o.
Further, the rotating speed of described gear ring transmission mechanism is 17 revs/min.
Further, the catch wheel device that the middle and lower part being also included in feed end is arranged.
Further, described feed end and the bottom outer wall of exhaust end are equipped with two groups of support rollers supported.
Further, described gear ring is arranged on drum sieve cylindrical shell by bolt.
Further, described support roller is arranged in frame.
Slag drum sieve of the present utility model; have the following advantages: first drop on sheath when slag enters screen drum body; impulsive force when slag enters has been cushioned by sheath; use sheath can protect screen drum body better, after sheath is damaged, directly change sheath; effectively can reduce the wearing and tearing of drum sieve feed end; avoid often changing drum sieve, can be greatly cost-saving, effectively improve mill slag screening efficiency.Slag is than general ore than great, and slag drum sieve is rotated by gear drive and driving, effectively can solve the large load operation of slag drum sieve.Define three-point fix by slag drum sieve support roller, pinch roller and gear wheel, make screen drum body can not transfer to depart from support roller due to high-speed rotary, be thrown out of.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
A kind of slag drum sieve, comprise column-shaped barrel 4, cylindrical shell both ends open is feed end and exhaust end respectively, described cylindrical shell 1 is in skewed, wherein the rational height of feed end is higher than the rational height of exhaust end, sieve aperture array is provided with between feed end and exhaust end, hopper 8 is provided with bottom sieve aperture array, the inwall of feed end is provided with the sheath 1 that can change, exhaust end is provided with deslagging bucket 5, the bottom outer wall of drum sieve feed end and exhaust end is equipped with the support roller 9 supported, the top exterior walls of cylindrical shell feed end and exhaust end is equipped with pinch roller 3 device, the gear ring transmission mechanism 10 that drum sieve cylindrical shell outside is provided with gear ring 2 and drum sieve is rotated with the speed of 14 ~ 20 turns per minute.The angle of inclination of described drum sieve cylindrical shell 1 is 5o ~ 8o.Gear wheel 6 device can also be set in the middle and lower part of feed end.Described feed end and the support roller set by the bottom outer wall of exhaust end 9 are two groups.Described gear ring is arranged on drum sieve cylindrical shell by bolt.Described support roller 9 is arranged in frame 7.
Embodiment 1: gear ring 2 bolt is arranged on cylindrical shell 4, transmission device 10 drives gear ring to rotate thus drives cylindrical shell to rotate, and the feed end of cylindrical shell is higher than exhaust end, and its mounted angle and horizontal line are 5o ~ 8o, is preferably 6o.Sheath 1 is installed on the feed end inwall of cylindrical shell 4, and cylindrical shell is provided with sieve aperture display between feed end and exhaust end.The feed end of cylindrical shell and the bottom outer wall of exhaust end are equipped with two support rollers 9, and described support roller is arranged in frame 7, and the feed end of cylindrical shell and the top exterior walls of exhaust end are equipped with pinch roller 3.In the bottom of the sieve aperture array segment of cylindrical shell, hopper 8 being installed, for collecting the slag meeting dimensional requirement, deslagging bucket 5 being installed outside the exhaust end of cylindrical shell, for collecting the slag not meeting dimensional requirement.The gear wheel 6 of the middle and lower part setting of feed end.
When drum sieve works, the rotating speed of drum sieve cylindrical shell reaches 14 ~ 20 revs/min, best results when reaching 17 revs/min.Material is first fallen on sheath, and then the sieve aperture array portion entering cylindrical shell sieves, and the granule meeting dimensional requirement falls in hopper by sieve aperture discharge, and bulky grain is then discharged from exhaust end and fallen in deslagging bucket.When wearing and tearing appear in sheath, only need to change sheath, thus extend the service life of drum sieve cylindrical shell.And all having two support rollers to hold screen drum body at the feed end of cylindrical shell and exhaust end, top has pinch roller to push down, and screen drum body also can not be run out of when High Rotation Speed between two support rollers.
