Description
Technical field
The utility model relates to a kind of spiral discharge sedimentation centrifuge, particularly the anti-corrosion spiral discharge sedimentation centrifuge of a kind of high-strength abrasion-proof.
Background technology
Promote and practice through publicity in recent years, solid-liquid separating equipment of new generation---the spiral discharge sedimentation centrifuge as coming out after vacuum press filter, plate and frame filter press, the belt filter press progressively enters Environmental Protection in China and production field.It takes up an area less, automatic operating, good separating effect, cleans the favor that production, unique advantage that cost performance is high more and more are subject to users with it.
Spiral discharge sedimentation centrifuge is by its supporting way, is divided into horizontally and vertical, then is divided into parallel type and reverse-flow two kinds by the type of flow of material in rotary drum.(see accompanying drawing one) as an example of the parallel type horizontal spiral discharge sedimentation centrifuge example, its operation principle is: material (suspension) is by feed pipe, and the distribution cabins through spiral inside enters rotary drum, and rotary drum and spiral are according to certain poor rotating speed rotating Vortex; Under the powerful centrifugal action that High Rotation Speed produces, the solid phase particles that density is larger in the suspension is deposited on the inwall of rotary drum, forms outer circular layer, and the light liquid that density is less then forms inner circular layer; On-stream spiral constantly scrapes and pushes to rotary drum cone end with solid phase from drum inner wall, then discharges body by the solid slag outlet of discharge end, and liquid phase then flows to the rotary drum styletable and overflows through overfall, thereby has realized Solid-Liquid Separation.
Be not difficult to find out by accompanying drawing one and above explanation:
1, whether good the material of centrifuge is, configuration rationally whether, the structure ﹠processes advanced person whether be determine centrifuge separating effect and service life length key factor.
2, not only can affect the range of application of centrifuge with wear-resistant, the corrosion resistance of material contact site, more can determine the service life of centrifuge.

1, for saving cost of manufacture, a lot of medium and small centrifuge manufacturing enterprise adopts the light-duty imported bearing of domestic bearing or relative low price, support then uses general steel plate or shaped steel welding, and large small end (main shaft) also is weldment processing, and differential mechanism is then take the cycloid differential mechanism as main.
2, for prolonging the service life of horizontal screw machine, solve the wear resistant corrosion resistant problem of centrifuge, a lot of producers think hard.Main way is; For the large separate object of solid Density coated with hard alloy (wc, w2c) or ceramic embedded on some parts, ceramic jacket.Be to increase the decay resistance of equipment, that the manufacturer takes or improving the base material class as main, as adopt 316 stainless steels or two phase stainless steel.But consequently; Device fabrication cost and burden for users obviously strengthen, but equipment wear resistant corrosion resistant ability and element resistance to brittle fracture can be also not fully up to expectations.
Therefore, how can be under the prerequisite that increases not significantly centrifuge production cost and burden for users, wear-resistant, the decay resistance of Effective Raise spiral discharge sedimentation centrifuge have been to work as forward swing in us scientific research personnel and manufacturing enterprise's important topic in front.
