The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in 1, insulation pellet truck spreader of the present utility model is made up of feeder hopper 1 and screen cloth 2 etc., and screen cloth 2 is positioned at the below of the discharging opening 11 of feeder hopper 1, and the net wall 12 of screen cloth 2 is the closed conical surface, its vertex of a cone is relative with discharging opening 11, and the screen-aperture of screen cloth 2 adapts with the order number of insulation pellet.The below of screen cloth 2 is provided with carriage 3, and feeder hopper 1 is connected with carriage 3 by strut bar 5, and screen cloth 2 is positioned at the space that is surrounded by discharging opening 11, strut bar 5 and carriage 3.
During spreading insulation pellet, truck spreader of the present utility model placed the container port of containing molten steel or molten iron directly over, to be incubated pellet by artificial or mechanical transmission device and send into feeder hopper 1 from the inlet point 10 of feeder hopper 1 upper end, by gravity falls through discharging opening 11, the insulation pellet is behind the vertex of a cone of the net wall 12 of falling the screen cloth 2 relative with discharging opening 11, the conical surface along net wall 12 rolls downwards, the insulation pellet is constantly worn from the sieve aperture of screen cloth 2 in the rolling process, thereby forms uniform heat-insulation layer on molten steel or molten iron surface.
For being incubated grain equably on the whole surface of spreading molten steel or molten iron in container, the end of the net wall 12 of screen cloth 2, is suitable along port shape, the size of shape, size and molten steel or molten iron container, so also can avoid the insulation pellet is dispensed onto outside the container.
The vertical line of centers of the axis of screen cloth 2 and discharging opening 11 coincides, and the insulation pellet shunting of the vertex of a cone of the net wall 12 of screen cloth 2 to constantly falling makes it be distributed in the whole conical surface of the net wall 12 of screen cloth 2 equably.The net wall 12 of screen cloth 2 forms 45～75 ° of angles with the axis of screen cloth 2.
In order to reduce the airborne dust in the spreading process, feeder hopper 1 is connected with the dust boot 4 that all around reach top of coating by described discharging opening 11, strut bar 5, carriage 3 space that surrounds on the position that is lower than inlet point 10 ports, reduce airborne dust in the insulation pellet spreading process, thereby help the improvement of production environment.
Insulation pellet truck spreader of the present utility model can reduce labor strength effectively, under the situation of artificial feeding, the operator will be incubated pellet with steel shovel and send into inlet point 10 on the material conveying platform that adapts with inlet point 10 height and positions, undoubtedly can than manually raise spread much laborsaving.Insulation pellet truck spreader of the present utility model can also combine with material conveying mechanism (as band conveyor etc.) easily and realize being incubated the mechanization spreading of pellet, thereby reduces operator's labour intensity to greatest extent and raise labour productivity.
