Description
Technical field
The utility model relates to the powder balling-up equipment of the industries such as metallurgy, mine, coal, refractory material, chemical industry, building materials, especially for the ball press of powder pressure ball.
Background technology
In the industries such as metallurgy, mine, coal, refractory material, chemical industry, building materials, usually to some materials as Iron concentrate, chromite powder, magnesia powder, powdered copper concentrate, chromite ore fine, manganese mineral powder, lateritic nickel ore, plumbous Zn scrap returns, aluminium vanadine, nonferrous metal powder, calcium lime powder, dolomite dust, refractory matter, ceramic material, steel mill's iron content powder, converter mud, brown iron oxide etc. make pelletizing, to smelt and calcining so that enter stove.Its method is mixed above-mentioned powder and binding agent, makes through production processes such as mixing, briquetting, oven dry.One procedure of its key is briquetting, in order to improve the uniformity of output and guarantee pelletizing size, all adopt rolling high-pressure ball press manufacture now, above-mentioned material is sent to roll-in between relative rolling type high-pressure ball press roller through feeding machine, owing to roll surface having made a lot of ball-and-socket, compound is by being just pressed into pelletizing after roller.Detect the whether qualified method of pelletizing compacting normally pelletizing fall hard rubber sheet from 0.5 meter of eminence and do not split for 20 times for qualified, it is closely knit that this just requires pelletizing to suppress.There is the shortcomings such as cost is high, the roll surface life-span is short, balling ratio is low, power consumption is high in present ball press.We have an important discovery in the process of research ball press pressure ball: because material is mandatory feeding in feeding machine, feeding machine has carried out compression to a certain degree to material, but the pressor areas entering ball-and-socket roll surface from feeding machine has a segment distance, material is loose again in the process of flowing, makes forced feed almost make idle work; Add material and contain binding agent, in the process of pressure ball by air seal in pelletizing, make pressure roller need very high pressure just can be pressed into qualified pelletizing, however, balling ratio is still quite low; In the process of pressure ball, in order to make pelletizing have time enough to be vented, must carry out at very low speeds, production efficiency is very low; And traditional ball press system is quite huge, make its manufacturing cost quite high.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, a kind of ball press for powder pressure ball is provided, extruder is utilized to be suppressed in pressure cuffs by material closely knit, the process of this binder does not need the high-power of routine, and owing to vacuumizing, do not need exhaust during sheeted product rod, make material be easy to compacting closely knit; Material rod roller is cut into pelletizing also without the need to high-power by form roller, and the power of this ball press is little, balling ratio is high, output is large, equipment availability is high, volume is little, cost is low.
The technical solution adopted in the utility model is as follows:
Ball press for powder pressure ball of the present utility model, comprise conveyor screw, extruder, pressure cuffs, form roller and vacuum system, described conveyor screw is by vacuum storehouse connecting extruder, described vacuum storehouse is connected with vacuum system, makes to be in vacuum state in described conveyor screw and extruder; The exit of described extruder is provided with pressure cuffs, and the pressure of material suffered by described pressure cuffs is more than 4MPa, and the outlet of described pressure cuffs is placed between two form roller of pairing.
Due to said structure, utilize extruder to be suppressed in pressure cuffs by material closely knit, wherein in pressure cuffs, the pressure of material is more than 4MPa, material just can be made to suppress closely knit; The process of this binder does not need to resemble power very large conventional ball press, and owing to vacuumizing, does not need exhaust, make material be easy to compacting closely knit during sheeted product rod; Material rod roller is cut into pelletizing by form roller does not need too large power yet; Needs according to output can multiscrew parallel connection.So this power for the ball press of powder pressure ball is little, balling ratio is high, output is large, equipment availability is high, volume is little, cost is low.During work, material enters in extruder through conveyor screw, vacuum system vacuumizes the material in extruder, evacuated material enters pressurized segment by the transportation section of extruder and suppresses closely knit, closely knit material is formed in pressure cuffs, be output into closely knit material rod by the outlet of pressure cuffs, material rod enters the form roller that locking phase rotates, and material rod roller is cut into pelletizing by the molding cutter on form roller.
Ball press for powder pressure ball of the present utility model, the vacuum system that described vacuum storehouse connects, makes the vacuum in conveyor screw and extruder be 760 holder ~ 10
-3holder.
Said structure, vacuum system is made up of vavuum pump and servicing unit, can be fixed, also can be portable, vacuumizes material in material in conveyor screw guide and extruder guide, and vacuum is that low vacuum is arrived in black vacuum, i.e. 760 holders ~ 10
-3holder.
Ball press for powder pressure ball of the present utility model, the screw rod group being provided with single screw rod in described extruder or being complemented each other to form by two or more screw rod; In wherein said screw rod group, the hand of spiral of screw rod is in the same way or oppositely.
Ball press for powder pressure ball of the present utility model, wherein two form roller be circumferentially evenly equipped with some molding cutters, between two molding cutters of arbitrary neighborhood, there is certain gap, the mutual corresponding matching of molding cutter during two form roller synchronous axial system on it; Wherein said molding cutter is made up of Hardmetal materials, and the percentage by weight of its composition is 6%Co+4%Ni+2%Cr+ surplus WC, after shaping compacting and low pressure sintering, fine finishining forms again, be embedded on form roller, it is convenient to change, the cutting knife that can current material selected as required to make.
Due to said structure, form roller has circumferentially evenly installed several molding cutters, and molding cutter is made up of Hardmetal materials, ensures that its service life is not less than 12000 hours.
