Screw feeder (1) is fixed on support (2), and screw feeder (1) discharge gate adopts the screw butt joint fixed with the extruder feed inlet, and install on adjustment Assembly (3) support (2), and whole equipment is supported by base (4), be equipped with hopper (6) on screw feeder (1), the inside screw rod of hopper includes rivet section (5) and helical blade section (7). Feeding machine is forced to tilting, feed screw rod anterior segment are the rivet section, and the back end is the auger delivery section, satisfy the breakage, break to encircle and force the three functional requirement of feed, can make the feed volume of gluey preparation in -process shoddy of regenerating and the stability of feed increased substantially. This device is fit for using the measurement feed based on in screw extruder's the old and useless rubber serialization desulfurization production process.
Description
Technical field
The utility model relates to a kind of viscosity powder forced-feeding device, is especially applicable to the feeding of the desulfurization rubber powder be applied in the regenerating waste used rubber process of screw extruder, belongs to field of cyclic utilization of waste rubber.
Background technology
China is tire production, consumption big country, and according to statistics, junked tire annual production in 2013 has reached 1,000 ten thousand tons, expects the year two thousand twenty junked tire output and will reach about 2,000 ten thousand tons.Prepare the main mode that reclaimed rubber is current China scrap rubber cycling and reutilization.Adopt HTHP digester to carry out devulcanization of rubber regeneration in conventional regeneration glue industry, but be eliminated gradually because of open, discrete mode of production.The substitute is environment-friendly type set type dynamic desulphurization plant continuously, but in the production process of serialization, harsh requirement is proposed to the continuity of feeding, stability.
Waste rubber powder in process of production main Problems existing is that its mobile performance is very poor, in the process procedure of especially back segment, the shoddy of partial desulfurization presents the characteristic of high sticky powder, very easily conglomeration, fluctuating widely easily appears in feed rate, is difficult to control effectively to feed rate.The feed rate fluctuated widely not only has a great impact the normal operation of complete desulfurization unit, and can cause the fluctuation of reclaimed rubber performance, affects the stability of reclaimed rubber quality.
Spiral forced feed because its transfer efficiency is high, safe and reliable, the advantage such as simple, the good airproof performance of structure is widely used in powder industry.Find in the production process of the regenerating waste used rubber of serialization that common spiral forced feed machine is difficult to meet the efficient control to feed rate under high yield.Because the height of desulfurization rubber powder glues characteristic, in continuous prodution process, require that feeding equipment can carry out fragmentation to caking rubber powder timely and effectively, need to possess broken arch and pressure binder two functions in addition.
Utilize spiral forced feed equipment advantage, and on this basis design is optimized to its machine barrel, blade construction etc., make it the functional requirement meeting reclaimed rubber industry continuous prodution.
Summary of the invention
The purpose of this utility model is: by manufacturing and designing a tilting forced feed machine, meets fragmentation, broken arch and forced feed three functional requirements, improves the feeding efficiency of shoddy and the stability of feeding in reclaimed rubber preparation process.
A kind of tilting forced-feeding device, is characterized in that: screw feeder 1 is fixed on support 2, and it is fixing that screw feeder 1 discharging opening and extruder charging aperture adopt screw to dock, and support 2 is arranged on adjustment member 3, and whole equipment is supported by pedestal 4; Screw feeder 1 is equipped with hopper 6, the screw rod of hopper inside comprises rivet section 5 and helical-blade fragment 7.
Further, screw feeder 1 axis and horizontal plane angle are 10 ° ~ 70 °.
Further, machine barrel inner surface, rivet surface and the equal anticorrosion with painting material of helical blade surface.
Further, screw rod closed section length n:D≤n≤2D, D is screw feeder diameter.
Further, screw rod closed section n: screw rod open segment m≤1:1.
Further, helix length t:1.5D≤t≤3D in screw rod open segment, all the other are rivet section, and D is screw feeder diameter.
Further, screw feeder is single-screw, plectonemic spiral or incorgruous double helix.
Further, adjustment member welds four threaded post, by adjusting nut fastening height adjustment screw feeding machine height.
The rivet section screw rod of hopper inside can carry out effective fragmentation to caking materials, and the helical-blade fragment that length is at least 1.5D can ensure the uniform and stable of mass transport.Machine barrel inner surface after spraying lubricious material and helical blade surface effectively can prevent the bonding of high sticky material, reduce the frictional force of material and contact surface simultaneously, reduce energy consumption.
Tilting feed machine has following several obvious advantage:
1, conveying aspect: tilted spiral relies on spiral thrust and gravity transfer material, has stronger conveying capacity, have higher feeding stability than vertically arranged spiral than horizontally disposed spiral;
2, broken arch aspect: tilted spiral and material powder contact area are larger, and hopper inner end spiral has certain difference in height, relative to flat spin, its broken arch ability has had and has greatly promoted, and is more applicable to the conveying feeding of high sticky powder;
3, tilted spiral feeding machine can carry out angle adjustment according to turning to of extruder screw, reaches optimum feeding angle, increases substantially extruder powder feeding efficiency.
The utility model is as the forced feed equipment in shoddy continuous desulfurization production process, and feed rate efficient stable, while ensure that properties of product, energy consumption is lower, for the regenerating waste used rubber of serialization provides technical guarantee.
