Abstract
A kind of coal powder injection impurity removal roller, relate to industrial equipments and facility, comprise cylinder and crushing knife, cylinder is right cylinder, drums inside runs through a main shaft and main shaft is connected by key with cylinder, the main shaft left and right sides is provided with bracing frame A and bracing frame B and bracing frame A and bracing frame B is positioned at cylindrical outer, chuck is provided with on the right side of main shaft, cylinder is provided with crushing knife A, be provided with crushing knife B on the left of crushing knife A, on the left of crushing knife B, be provided with crushing knife C, on the left of crushing knife C, be provided with crushing knife D, be crushed on the left of D and be provided with crushing knife E, on the left of crushing knife E, be provided with crushing knife F.Described crushing knife and cylinder are by being welded and fixed.Put by the staggered of crushing knife, can accomplish to enter coal cinder in impurity removal roller to blending, the coal after blending enters into and can reduce blast furnace coal gun in the middle of coal rifle and block up rifle number of times, improves grinding efficiency and Coal Injection Rate at BF, reduce blast furnace coke ratio simultaneously, substantially increase production efficiency.
Description
technical field:
The utility model relates to industrial equipments and facility, is specifically related to a kind of coal powder injection impurity removal roller.
background technology:
Along with the development in epoch, the progress of science and technology, steel-making is extremely people's concern, but existing impurity removal roller is level and smooth right cylinder, can only accomplish simple removal of impurities, be easy to coal rifle is blocked when the coal of bulk enters in the middle of blast furnace coal gun, when coal rifle sprays, cracked cinder is uneven to be made, the coke ratio of blast furnace can be improved, in order to solve the problems of the technologies described above, a kind of new technical scheme of special proposition.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of coal powder injection impurity removal roller, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of coal powder injection impurity removal roller, comprise cylinder and crushing knife, cylinder is right cylinder, drums inside runs through a main shaft and main shaft is connected by key with cylinder, the main shaft left and right sides is provided with bracing frame A and bracing frame B and bracing frame A and bracing frame B is positioned at cylindrical outer, chuck is provided with on the right side of main shaft, cylinder is provided with crushing knife A, crushing knife B is provided with on the left of crushing knife A, crushing knife C is provided with on the left of crushing knife B, be provided with crushing knife D on the left of crushing knife C, be crushed on the left of D and be provided with crushing knife E, on the left of crushing knife E, be provided with crushing knife F.
Described crushing knife and cylinder are by being welded and fixed.
The beneficial effects of the utility model are: put by the staggered of crushing knife, can accomplish to enter coal cinder in impurity removal roller to blending, coal after blending enters into and can reduce blast furnace coal gun in the middle of coal rifle and block up rifle number of times, improve grinding efficiency and Coal Injection Rate at BF, reduce blast furnace coke ratio simultaneously, substantially increase production efficiency.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Fig. 2 is side-view of the present utility model.
embodiment:
With reference to Fig. 1, a kind of coal powder injection impurity removal roller, comprise cylinder 7 and crushing knife, cylinder 7 is right cylinder, cylinder 7 inside runs through a main shaft 11 and main shaft 11 is connected by key with cylinder 7, main shaft 11 left and right sides is provided with bracing frame A8 and bracing frame B9 and bracing frame A8 and bracing frame B9 is positioned at cylinder 7 outside, chuck 10 is provided with on the right side of main shaft 11, cylinder 7 is provided with crushing knife A1, crushing knife B2 is provided with on the left of crushing knife A1, crushing knife C3 is provided with on the left of crushing knife B2, crushing knife D4 is provided with on the left of crushing knife C3, be crushed on the left of D4 and be provided with crushing knife E5, crushing knife F6 is provided with on the left of crushing knife E5.Described crushing knife and cylinder 7 are by being welded and fixed.Put by the staggered of crushing knife, can accomplish to enter coal cinder in impurity removal roller to blending, the coal after blending enters into and can reduce blast furnace coal gun in the middle of coal rifle and block up rifle number of times, improves grinding efficiency and Coal Injection Rate at BF, reduce blast furnace coke ratio simultaneously, substantially increase production efficiency.
