Abstract
The utility model discloses a wear-proof structure of a helical blade in a horizontal helical centrifuge. The wear-proof structure comprises a helical blade body, wherein the helical blade body comprises a working surface and a non-working surface; a wear-proof structure layer is arranged on the side of the working surface of the helical blade body; and a replaceable wear-proof block is arranged at the top end of the side of the working surface of the helical blade body. The wear-proof structure layer and the replaceable wear-proof block are arranged on the working surface of the helical blade of the horizontal helical centrifuge, so that the abrasion of the helical blade is reduced, and the service life of the centrifuge is prolonged; in addition, as the wear-proof block is connected with the helical blade body by a screw, the wear-proof block arranged on the helical blade is quick and convenient to replace and maintain even if being abraded.
Description
Technical field
The utility model relates to a kind of horizontal screw centrifuge internal structure, is specifically related to a kind of horizontal screw centrifuge helical blade abrasion-proof structure.
Background technology
Horizontal type screw settling centrifuge is a kind of efficient centrifugal separation equipment referred to as horizontal screw centrifuge.
Horizontal screw centrifuge is the precipitation apparatus of a kind of horizontal screw unloading, continued operation.The operation principle of this class centrifuge is: rotary drum and spiral rotate with certain differential same-directional high-speed, material is introduced conveying spiral inner core continuously by feed pipe, enter rotary drum after the acceleration, under effect of centrifugal force, heavier solid formation is deposited on and forms the sediment layer on the rotatory drum wall; The conveying spiral continuously is pushed into rotary drum cone 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 continuously rotary drum by the large end overfall of rotary drum, outside leakage fluid dram discharge machine.
Horizontal screw centrifuge is to utilize centrifugal force the different mixed material of proportion to be carried out the equipment of Separation of Solid and Liquid, the helical blade of horizontal screw centrifuge mainly is to make of stainless steel at present, but because stainless steel hardness is low, easily cause the wearing and tearing of screw feeder, thereby affect dynamic balancing and the disposal ability of centrifuge, shorten widely the service life of centrifuge, and this helical blade is unsuitable for the special material processing the sand factor height, can cause heavy wear especially.
The utility model content
Consider the problems referred to above of prior art, according to an aspect of the present utility model, a kind of horizontal screw centrifuge helical blade abrasion-proof structure is disclosed, comprise the helical blade body, described helical blade body comprises working face and non-working surface, it is characterized in that the working face side of described helical blade body is provided with wearproof structural tier, the top of described helical blade body working face side is provided with removable wear-resistant block.
As preferably, described wearproof structural tier is the tungsten carbon alloy wearing layer of high temperature surfacing.
As preferably, the tungsten carbon alloy wearing layer thickness of described high temperature surfacing is 0.5mm-1mm.
As preferably, be connected by screw between described wear-resistant block and the helical blade body.
As preferably, described screw is sunk screw.
As preferably, described wear-resistant block is for to be made by the tungsten carbon alloy.
It is simple that the purpose of this utility model aims to provide a kind of making, changes easyly, quick, has the horizontal screw centrifuge helical blade structure in higher service life.Compared with prior art, one of the beneficial effects of the utility model are:
1, the utility model arranges wearproof structural tier and removable wear-resistant block at the working face of horizontal screw centrifuge helical blade, the wearing and tearing of helical blade have been reduced, increased the service life of centrifuge, wherein be connected by screw between wear-resistant block and the helical blade body, even the wear-resistant block that arranges on the helical blade has worn and torn, also can conveniently change and safeguard;
2, use horizontal screw centrifuge of the present utility model, in actual moving process, the gap between rotary drum and helical blade changes minimum, makes separating effect stable, better, can make centrifuge be in for a long time high efficiency, good separating effect and stable optimum state, energy-conserving and environment-protective.
3, utilization of the present utility model obviously reduces the centrifuge fault rate, and service life, more common horizontal screw centrifuge was long about 5～8 times, and can use continuously at full capacity for a long time, had improved production efficiency, had reduced cost.
Description of drawings
Fig. 1 shows the structural representation according to the horizontal screw centrifuge helical blade abrasion-proof structure of an embodiment of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified, but embodiment of the present utility model is not limited to this.
Fig. 1 shows the structural representation according to the horizontal screw centrifuge helical blade abrasion-proof structure of an embodiment of the utility model.Horizontal screw centrifuge helical blade abrasion-proof structure as shown in Figure 1, comprise helical blade body 101, the helical blade body comprises working face 102 and non-working surface 103, working face 102 1 sides of helical blade body 101 are provided with wearproof structural tier 104, the top of helical blade body 101 working faces 102 1 sides is provided with removable wear-resistant block 105, is connected by sunk screw 106 between wear-resistant block 105 and the helical blade body 101; Wearproof structural tier 104 is the tungsten carbon alloy wearing layer of high temperature surfacing, and thickness is 0.5mm-1mm; Wear-resistant block 105 is for to be made by the tungsten carbon alloy.
The utility model arranges wearproof structural tier and removable wear-resistant block at the working face of horizontal screw centrifuge helical blade, the wearing and tearing of helical blade have been reduced, increased the service life of centrifuge, wherein be connected by screw between wear-resistant block and the helical blade body, even the wear-resistant block that arranges on the helical blade has worn and torn, also can conveniently change and safeguard.And horizontal screw centrifuge when work material mainly concentrates on helical blade near on the working face on top, so the utility model is installed removable wear-resistant block at this position, and with sunk screw make it with the helical blade body between be connected, guaranteed centrifuge dynamic balancing and disposal ability, made the long-term continuously normal operation of centrifugal function.Use horizontal screw centrifuge of the present utility model, in actual moving process, the gap between rotary drum and helical blade changes minimum, makes separating effect stable, better, can make centrifuge be in for a long time high efficiency, good separating effect and stable optimum state, energy-conserving and environment-protective.Utilization of the present utility model obviously reduces the centrifuge fault rate, and service life, more common horizontal screw centrifuge was long about 5～8 times, and can use continuously at full capacity for a long time, had improved production efficiency, had reduced cost.
