Description
Technical field
The present invention relates to a kind of tank battery welder, particularly natural gas storage tank assembly-welding device.
Background technology
Rise steadily in magnetic iron ore price on the current international market, the bloodstone price is stably in the situation, metallurgy industry is constantly pursued and is used whole bloodstone and produce pelletizings both at home and abroad.Because the restriction of bloodstone grinding and flotation technology, hematite pellets production technology, pellet production line is the red fine iron breeze of admixture on a small quantity.It is the target that domestic and international metallurgy industry is pursued that 100% use bloodstone is applied to pelletizing production always.Because the restriction of technology, domestic smelter can only be used a small amount of ground hematite in iron ore sintering is produced, have to abandon cheap import bloodstone.Using pellet, improve the capacity factor of a blast furnace, is the developing direction of present ironmaking technology.Domestic grinding to iron ore adopts fragmentation-roller mill-ball milling-magnetic separation (flotation) technique usually.Especially the grinding of bloodstone, complex process, low, the contaminated environment of production efficiency.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of vertical breeze dry mill, it is simple in structure, and production efficiency is high, environmental protection.
The present invention solves the technical scheme that its technical problem takes: the fixing powder selector that communicates with cabinet in the upper end of cabinet, meal outlet is arranged on the powder selector, powder selector is by motor-driven, in the cabinet by the fixing mill of mill spindle and bearing, mill spindle is by main motor-driven, there is grinding roller the mill top, grinding roller passes through shaft of grinding roller, bearing hinge connection is on pressure frame, one end of pressure frame and crank is hinged, the other end of crank is fixed by bearing block and cabinet, and the actuating arm of crank and oil cylinder is hinged, and oil cylinder and cabinet are hinged, on the described cabinet charging aperture is arranged, there is a vane at the place, outer of described mill.
The present invention has following advantages: be applied to 1), first the dry grinding of rich ore powder, especially process the ground hematite below the 5mm that metallurgy industry is difficult to use, belong to pioneering in that international rich ore grinding is technical.2), the present invention is applied to pellet production line, improve the utilization rate that bloodstone is applied to pelletizing production, opened up new pellet feed source.3), simple in structure, production efficiency is high, environmental protection.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is front view of the present invention.
The specific embodiment
As shown in drawings, the fixing powder selector 7 that communicates with cabinet in the upper end of cabinet 9, meal outlet (not shown in FIG.) is arranged on the powder selector 7, powder selector 7 is driven by motor 11, pass through fixedly mill 9 of mill spindle 8 and bearing in the cabinet 10, mill spindle 8 is driven by main motor (not shown in FIG.), there is grinding roller 6 mill 9 tops, grinding roller 6 is by shaft of grinding roller 4, bearing hinge connection is on pressure frame 5, and pressure frame 5 is hinged with an end of crank 3, and the other end of crank 3 is fixing with cabinet 9 by bearing block 2, crank 3 is hinged with the actuating arm of oil cylinder 1, oil cylinder 1 is hinged with cabinet 9, and charging aperture (not shown in FIG.) is arranged on the described cabinet 9, and there is a vane at the place, outer of described mill 9.
Described oil cylinder 1, crank 3, shaft of grinding roller 4 and grinding roller 6 have three covers, and mill spindle 8 is evenly distributed on around the mill 9 relatively.
Material is delivered on the mill 9 by charging aperture, and when mill 9 rotated, material was rolled pulverizing by the motion between mill 9 and the grinding roller 6, and the material that is crushed to certain fineness is outwards overflowed by the rotation centrifugal force of mill 9.There is a vane at place, mill 9 outers, the air-flow useless matter that proportion in the material is larger that rises falls into below the vane, discharge body through scraper plate, and the material that meets a certain fineness requirement is upwards carried by air-flow, material separates after arriving powder selector 7, and the material of a certain fineness is sent, and the material that granularity is larger is thrown on cabinet 9 inwalls by powder selector 7, fall into again mill 9, again grinding.
