Description
Technical field
The present invention relates to a kind of gravitational method preparation equipment manufacturing technology, more particularly, it relates to a kind of sectional injection-moulding processing method of spiral ore dressing chute.
Background technology
Spiral ore dressing chute is commonly called as spiral concentrator, and it is applied and the history of device fabrication existing three more than ten years.This product on the market is mainly with material manufacturings such as fiberglass, polyurethane, metal, plastic plates.Be applicable to that iron ore, ilmenite, chromite, troilite, tin ore, tungsten ore, tantalum niobium concentrate, zircon sand, rutile, monazite, phosphorus second ore deposit and all that of graded shot have other mineral bodies of difference of specific gravity.Its ore dressing principle is: moisture ore pulp follows chute from this equipment top and freely flows down, because the difference of specific gravity of ore in sand form and other sand grains, make the different particle of proportion in the ore pulp separated gradually by centrifugal action in through four to five all screws at the chute slideway, intercept the mineral of different specific weight at spiral chute outlet at bottom place respectively, reach mineral and sort purpose.This equipment is unpowered, and water consumption is few, wear-resistant, in light weight, it is easy easily to move and keep in repair, and available multiple devices are combined into the spiral chute ore dressing group system of scales such as large, medium and small type.
At present, the method for production spiral ore dressing chute has following several:
One. the processing method made from metal material: the plane plate that earlier sheet metal is cut into definite shape, be shaped into certain curved surface with the mould punching press, again the metal curved surface plate front and back of reserving type are welded into coherent conveyor screw, and fixedly form whole spiral ore dressing chute with the newel welding.The spiral of each all 360 ° of radian generally has 6-8 piece metal curved surface plate to be welded.This is the product of phase very early, because it wears no resistance, is eliminated by market already.
Two. the processing method made from polyurethane material: the processing technology that adopts the unitary mould moulding by casting.Because it is good that it has wearability, good characteristics such as long service life make it occupy suitable share on expensive goods market.Its shortcoming is to cost an arm and a leg.
Three. the processing method made from glass-reinforced plastic material: adopt the segmentation manual pasting forming process, with one week of spiral 360 ° of radians be one section.The small investment of this technology, technology are simple, production cost much lower than with polyurethane material, also can make producer when receiving in enormous quantities orders, the segmentation helical element is transported to the on-the-spot splicing of user install, to save the fortune cost of mixing; Shortcoming is that production process can produce environmental pollution, and the direct labor has the possibility of vinyl benzene poisoning.
Four. the processing method made from plastic plate: the plane plate that earlier plastic plate is cut into definite shape, it is soft to broadcast in the hot blast tunnel baking, be shaped into certain curved surface with the mould holder pressure, with plastic welding rod and hot blast plastic curved surface plate front and back are welded again, and be fixed on the newel, form whole spiral ore dressing chute.The conveyor screw of each all 360 ° of radian generally has 6-8 piece plastic curved surface plate to be welded.The investment of this technology is little, technology simple, production cost is more much lower than the usefulness glass-reinforced plastic material; Shortcoming is: the leftover bits loss after the plastic plate cutting is more; Plastics hot blast solder technology is had relatively high expectations; Equipment is wanted whole Transporting, and volume causes the freight and miscellaneous charges cost bigger greatly, and especially the transport by sea cost of products export is higher.
Summary of the invention
The object of the present invention is to provide a kind of manufacturing process technology simple, can large-scale production, the spiral ore dressing chute sectional injection-moulding processing method of low, the installation of production cost, convenient transportation.
The objective of the invention is to be achieved by following technical scheme.
Spiral ore dressing chute sectional injection-moulding processing method of the present invention may further comprise the steps:
A. the spiral chute section with 360 ° of radian circumference of arbitrary layer of spiral ore dressing chute is divided into more than two sections or two sections;
B. according to the technique of preparing requirement of spiral ore dressing chute, manufacture and design wherein one section plastics injection mould;
C. produce the plastic components of this section spiral ore dressing chute curved surface with the injection mo(u)lding processing method;
D. with plastic components piecemeal, successively combination is fixed on the newel of spiral ore dressing chute;
E. load onto into and out of hopper by the technique of preparing requirement.
Should be taken into account that at step b chute is secured to the anti-spilled baffle plate of mechanics support arm and chute outside of newel, and connection structure connecting before and after this section chute parts.
The plastic raw materials that is used for step c can be selected the plastic raw materials of various suitable injection mo(u)ldings for use.
The present invention compared with prior art has following beneficial effect:
1. manufacturing process technology is simple;
2. can be mass-produced;
3. production cost is low;
4. the transportation of product, easy for installation;
