Abstract
The invention discloses a highly abrasion-resisting polyurethane material composite spiral feeder which resolves the problem that an existing device is short in service life. The highly abrasion-resisting polyurethane material composite spiral feeder is characterized in that the front portion of a feeding end and the rear portion of a discharging end of a spiral shaft are respectively provided with a blocking disc; a polyurethane lining is lined inside an auger metal outer shell, a polyurethane lining is lined outside the spiral shaft, and polyurethane linings are lined on both surfaces of a spiral piece and the blocking discs. The raw materials of each polyurethane lining comprise prepolymer (MDQ23165), polyhydric alcohol (D20) and 1-4 butanediol (BDO), and the formula is that prepolymer: polyhydric alcohol: 1-4 butanediol = 100: 98.5: 11.85. The highly abrasion-resisting polyurethane material composite spiral feeder makes full use of the good performance of high polymer material polyurethane, integrates the good performance of the high polymer material polyurethane with the firmness of metal, can be widely applied to a material procedure switching process and design of accessories making direct contact with materials, and is suitable for various severe work conditions, the designed blocking discs prevent the materials from being accumulated on a bearing to a large extent and reduce abrasion to the bearing from the materials, and a product is stable in quality and long in service life.
Description
Technical field
The present invention relates to a kind of short distance mass transport, lifting equipment, relate to or rather the screw feeder that a kind of new material is produced.
Background technology
Screw feeder is a kind of equipment for the conveying of short range powdery, granular material.At present both domestic and externally all adopt a kind of screw auger, motor reduction gearbox by metallic cylinder frame, carbon steel or abrasion resistant cast steel welding to drive.Material is entered in cylinder by inlet point, is constantly pushed to auger outlet discharges by the moving auger flight of not stall, completes transfer or the lifting process of material.Its advantage is convenient and swift, can meet the requirement of any bad working environments.But use for a long time, particularly raw meal particle size is large, in the large situation of hardness, be easy to occur auger shell, the fast phenomenon of auger pad wear, particularly feeding mouth and discharging opening material are easily piled up at bearing place, cause for a long time the accessory life-span short, be difficult for maintenance, change, not only delay production and also bring a large amount of wastes.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art provides a kind of high abrasion polyurethane material composite screw feeder, and quick for installation, easy to maintenance, product life is grown, saves service expenditure, enhanced productivity.
The present invention includes motor, drop-gear box, bearing and bearing, auger metal case, screw shaft, flight, auger metal case, screw shaft, flight are metalwork, it is characterized in that: all design a backgauge dish in screw shaft feeding end front portion and discharge end rear portion; Described auger metal case liner polyurethane lining, described screw shaft outer lining polyurethane lining, described flight, backgauge dish two sides all serve as a contrast polyurethane lining.
The raw material of described polyurethane lining is made up of performed polymer (MDQ23165), polyalcohol (D20), 1-4 butylene glycols (BDO), and meter, fills a prescription as performed polymer: polyalcohol: 1-4 butylene glycols=100:98.5:11.85 by weight.
The process that described auger metal case, screw shaft, flight, backgauge dish serves as a contrast polyurethane lining is: the raw material of polyurethane lining is heated to 45 DEG C respectively in cating machine barrel, be incubated 12 hours, inject casting room by measuring pump, after the high-speed mixing of 1440 revs/min, be poured into respectively in the mould of auger metal case, screw shaft, flight, backgauge dish, with 45 DEG C of preheated skeletons be that auger metal case, screw shaft, flight, backgauge dish are respectively through being sulfided into an entirety.
Described backgauge dish diameter is more smaller than auger internal diameter of outer cover, plays the effect that reduces as far as possible material and accumulate to bearings at both ends place, avoids bearing damage, extends product life.
Technique scheme is known, the present invention designed polyurethane formula, be provided with processing mold, processing technology, increased backgauge dish, its structure and mounting means are optimized, make full use of the premium properties of polymer material polyurethane, make it to combine with the firm performance of metal, can be widely used in the accessory design that material process of transfer order directly contacts with material.1, there is the characteristics such as impact-resistant and high-wear-resistant, low friction and self-lubricating due to polyurethane, in the service life that can greatly improve equipment, reduce due to maintenance and the loss bringing that stops production.2, metallic framework outsourcing layer of polyurethane, can have the impregnability of metalwork and the elasticity of polyurethane product concurrently, is applicable to various severe working conditions.3, product is installed with full-metallic spiral feeder mode was identical originally, installs, safeguards that replacing is convenient, constant product quality, long service life.4, a backgauge dish is all designed at auger feeding end front portion and discharge end rear portion, has avoided to a great extent the accumulation of material at bearing place, has greatly reduced the wearing and tearing of material to bearing, has improved the equipment part life-span.Product uses through Duo Jia iron company raw material workshop, by original replacing in each month once, extends to 6-7 month, firmly gets user's favorable comment.
