Abstract
The invention relates to a blast furnace pad type weighing hopper which comprises a weighing hopper square enclosure, a weighing hopper conical enclosure and a weighing hopper discharge port, wherein the lower end of the weighing hopper square enclosure is fixedly connected with a big opening end of the weighing hopper conical enclosure, and the weighing hopper discharge port is formed at a small opening end of the weighing hopper conical enclosure. The blast furnace pad type weighing hopper is characterized in that collection boxes are uniformly distributed around the inner wall of the weighing hopper square enclosure, and the collection boxes are open upward; and the weighing hopper conical enclosure is of a step shape. The blast furnace pad type weighing hopper provided by the invention is low in cost, simple in structure and reliable in use.
Description
Technical field
The present invention relates to the height wearing and tearing weighing equipment of the field of metallurgy (or other industrial circle) such as ironmaking, steel-making, be specifically related to a kind of blast furnace gasket-type scale hooper.
Background technology
Scale hooper is widely used in metallurgy industry and other industrial circle, and scale hooper plays an important role as metering outfit in the ironmaking field.For fear of the wearing and tearing of the external acorn-cup wall of weighing material and the work-ing life of prolongation scale hooper, usually assemble abrasion-proof backing block (for example metal backing, ceramic lining plate and other high-abrasive material) at headwall.But the material price of above-mentioned abrasion-proof backing block is limited high work-ing life, and in use will often safeguard and regularly replace; Metal backing adopts bolt to fix, and nonmetal liner plate adopts binding agent to fix, and can cause liner plate to come off owing to material and managerial reason in the production process, metal backing come off can cause gate to damage and stuck, scratch the directly impact production such as conveyor.
Summary of the invention
The object of the present invention is to provide a kind of cost low, and simple in structure, service-strong blast furnace gasket-type scale hooper.
For achieving the above object, the technical solution used in the present invention is a kind of blast furnace gasket-type scale hooper, and it comprises scale hooper square shell, scale hooper conical shell and scale hooper feed opening; The lower end of scale hooper square shell is fixedly connected with the big opening end of scale hooper conical shell, and the osculum end of scale hooper conical shell is provided with the scale hooper feed opening; It is characterized in that: on the inwall of scale hooper square shell uniform ring around the material collecting box that distributing, the opening upwards of material collecting box; The scale hooper conical shell is notch cuttype.
The Nei Yanchu of described scale hooper feed opening is circumferentially with fixation steel plate, and four fixation steel plates form four adjustable plate slots with the inwall that is connected of batch box feed opening, are inserted with the charge level adjustable plate in each adjustable plate slot.
The invention has the beneficial effects as follows:
1. the present invention is with the form of backing strap, finishes the effect of liner plate by the mode of material dnockout, avoided impact and the friction of falling material to headwall, reduces to produce the work-ing life that prolongs scale hooper to consume, and reduces failure rate; The present invention uses reliably;
2. realize changing the effect of regulatory region material face by the height that changes adjustable plate, to adapt to the pile up angle of different specific weight;
3. the present invention is simple in structure, practicality is reliable, wide application, and cost is low.

Embodiment
In order to understand better the present invention, below in conjunction with embodiment and accompanying drawing technical scheme of the present invention is described further (referring to Fig. 1 to Fig. 9).
A kind of blast furnace gasket-type scale hooper, it comprises scale hooper square shell 1, scale hooper conical shell 4 and scale hooper feed opening 7; The lower end of scale hooper square shell 1 is fixedly connected with the big opening end of scale hooper conical shell 4, and the osculum end of scale hooper conical shell 4 is provided with scale hooper feed opening 7; Uniform ring is around the material collecting box 3 that distributing on the inwall of scale hooper square shell 1, the opening upwards of material collecting box 3; Scale hooper conical shell 4 is notch cuttype.
The Nei Yanchu of described scale hooper feed opening 7 is circumferentially with 8, four fixation steel plates 8 of fixation steel plate and forms four adjustable plate slots with the inwall 10 that is connected of batch box feed opening 7, is inserted with charge level adjustable plate 9 in each adjustable plate slot.
The technical parameter of above-mentioned parts can change according to the actual size of scale hooper.
Scale hooper feed opening 7 places arrange movable charge level adjustable plate 9, because of its motion angle of the material of different specific weight different with angle of repose, if on the scale hooper conical shell 4 the material face be fix just be difficult to satisfy different material surface of friction, the crude fuel proportion that blast furnace production consumes differ greatly (lump ore ~ 2.5t/m3, agglomerate ~ 1.8t/m3, coke ~ 0.5t/m3), adopt charge level adjustable plate 9 devices that the charge level adjustable plate 9 of corresponding height can be installed according to the angle of repose of material, play regulating effect by the charge level adjustable plate 9 that different heights is installed, apply in a flexible way.
After installation and debugging of the present invention were good, the material that advances scale hooper for the first time fell into material collecting box 3, the scale hooper conical shell exists the inside to do the liner plate that backing strap replaces conventional design, and this backing strap can life-time service.
Charge level adjustable plate 9 assigns in the adjustable plate slot, may wear to the charge level adjustable plate 9 that the height of setting can manually more renew when following and continues to use, and prolongs its work-ing life.
Above disclosed only is preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalence of therefore doing according to the present patent application claim changes, and still belongs to protection scope of the present invention.
