Description
Technical field
The present invention relates to a kind of horizontal screw centrifuge, relate in particular to a kind of horizontal screw centrifuge liquid outlet structure, belong to machinery manufacturing technology field.
Background technology
Horizontal screw centrifuge is the precipitation apparatus of a kind of spiral shell screw unloading for sleeping in, continued operation.Its course of work is: rotary drum and spiral are with the rotation at a high speed in the same way of certain differential, and material is introduced defeated material spiral inner core continuously by feed pipe, quickens the back and gets into rotary drum; Under effect of centrifugal force, heavier solid formation is deposited on and forms the sediment layer on the rotatory drum wall, and defeated material spiral continuously is pushed into rotary drum awl end with the solid formation of deposition; Outside slag-drip opening discharge machine; Lighter liquid phase thing then forms the internal layer pendular ring, overflows rotary drum continuously by the big end liquid outlet of rotary drum, outside leakage fluid dram discharge machine.Horizontal screw centrifuge often applies to silica flour class industry, petroleum drilling fluid class industry, steel industry; Along with the utilization field more and more wider, wear-resisting requirement has proposed high request to these industries to centrifuge, centrifuge is two separation of solid-liquid; Though the solid phase in the material can be because of the design of centrifuge structure; Major part is discharged from the solid phase mouth, but still can have the solid of certain content in the stillness of night, and solid hardness is bigger in the material that those industries are handled; Liquid outlet to big end flanges has caused wearing and tearing, and the wearing and tearing back receives very big influence to the intensity of big end flanges.
Summary of the invention
The technical issues that need to address of the present invention are: prevent that the big end flanges liquid outlet of horizontal screw centrifuge from receiving the influence generation wearing and tearing of solid material, improves the intensity of big end flanges liquid outlet, and prolong its service life.
The invention provides a kind of horizontal screw centrifuge liquid outlet structure; Comprise the poroid liquid outlet 2 of an open circles, lip ring 11, said lip ring 11 is connected with bottom, said liquid outlet 2 outer face; Can regulate the height of liquid level in the said horizontal screw centrifuge through the height of regulating said liquid baffle board 11; Also comprise a ring cylinder wear-resistant sleeve 6, said ring cylinder wear-resistant sleeve 6 outer circumference walls are nested and be fixed on said liquid outlet 2 inwalls, and its whole or exposed at least top layer is a hard wear-resistant material.
Said ring cylinder wear-resistant sleeve 6 comprises the stainless steel base 9 of a ring cylinder, coating one deck carbide alloy 10 on said stainless steel base 9 both ends of the surface and the inner peripheral wall.
The thickness of said carbide alloy 10 is 2 to 3mm.
Said annular wear-resistant sleeve 6 is adhesively fixed through glue and said liquid outlet 2 inwalls.
Said liquid blocking plate 11 also touches with the 6 outer face bottom virtual connection of said ring cylinder wear-resistant sleeve, props up said ring cylinder wear-resistant sleeve 6, prevents that it from axially sliding along liquid outlet laterally.
Said liquid outlet band extends out tapering, is horn mouth shape outwardly, prevents that said ring cylinder wear-resistant sleeve 6 from axially sliding along liquid outlet to the inside.
The said tapering that extends out is 1 ° to 3 °.
Said liquid outlet is arranged on the end face that said liquid outlet is arranged on the big end flanges that is connected with the inner drum structure of said horizontal screw centrifuge.
Beneficial effect of the present invention is: solved the influence that horizontal screw centrifuge big end flanges liquid outlet receives solid material and produced the technical problem of wearing and tearing, improved the intensity of big end flanges liquid outlet, and prolong its service life; Provide a kind of cost low, well-set wear-resistant sleeve structure has promptly reduced the cost of wear-resistant sleeve, has guaranteed being fastenedly connected between big end flanges and the wear-resistant sleeve, has also improved the wearability of big end flanges liquid outlet, has promoted the whole serviceability of centrifuge.

The specific embodiment
The invention provides a kind of horizontal screw centrifuge liquid outlet structure, comprise the poroid liquid outlet 5 of an open circles, lip ring 11, said liquid outlet are arranged on the end face of a flange, are connected through the inner drum structure of said flange and said horizontal screw centrifuge.Said lip ring 11 is connected with bottom, said liquid outlet 5 outer face; Can regulate the height of liquid level in the said horizontal screw centrifuge through the height of regulating said liquid baffle board 11; Also comprise a ring cylinder wear-resistant sleeve 6; Said ring cylinder wear-resistant sleeve 6 comprises the stainless steel base 9 of a ring cylinder, and coating one layer thickness is 2 to 3mm carbide alloy 10 on said stainless steel base 9 both ends of the surface and the inner peripheral wall.Said ring cylinder wear-resistant sleeve 6 outer circumference walls are nested and be fixed on said liquid outlet 5 inwalls, and said annular wear-resistant sleeve 6 is adhesively fixed through glue and said liquid outlet 5 inwalls.Said liquid blocking plate 11 upper ends exceed the bottom of said ring cylinder wear-resistant sleeve, prop up said ring cylinder wear-resistant sleeve 6, prevent that it from axially sliding along liquid outlet laterally.1 ° to 3 ° on said liquid outlet band extend out tapering, be horn mouth towards shape, prevent that said ring cylinder wear-resistant sleeve 6 from axially sliding along liquid outlet to the inside.
The present invention is in design wear-resistant sleeve structure, if the wear-resistant sleeve structure of using fully hard matter alloy material to process is protected the liquid outlet of big end flanges, owing to the carbide alloy expensive, and use amount is big; Cost can have a distinct increment, and causes certain waste, therefore through behind the wear-resistant sleeve that adopts the carbide alloy coated layer; Solved the cost problem, but after adopting alloy to cross the wear-resistant sleeve of layer, if with on the directly nested liquid outlet that is weldingly fixed on big end flanges of wear-resistant sleeve; Cause the carbide alloy of script surfacing on wear-resistant sleeve to drop easily, consider this point, decision uses glue to connect fixing big end flanges liquid outlet and wear-resistant sleeve; Simultaneously, big flange liquid outlet is made the shape that band extends out tapering, simultaneously wear-resistant sleeve is carried out axial restraint with lip ring; Prevent that it from endwisely slipping,, both improved the wearability of big end flanges liquid outlet through such measure; Reduce the cost of wear-resistant sleeve again, and guaranteed being fastenedly connected between big end flanges and the wear-resistant sleeve, promoted the whole serviceability of centrifuge.
