Abstract
The utility model discloses a become tapering auger delivery ware belongs to centrifuge technical field, including cylinder end and toper end, be provided with the screw-tupe blade to the toper end by the cylinder end on auger delivery ware's outer wall, the cone angle of auger delivery ware's toper end is and increases progressively the setting. The utility model discloses an increase cone angle, the direct backward flow speed that makes liquid accelerates, has also increaseed the handling capacity of material when increasing separation back solid phase material quality, through the method to different tapering auger delivery ware of different materials with the fortune, makes various materials all reach the best separation effect.
Description
Technical field
The utility model relates to a kind of centrifugal device, especially relates to a kind of auger conveyor of taper mutation of horizontal screw centrifuge.
Background technology
Current horizontal screw centrifuge as shown in Figure 1, horizontal screw centrifuge generally comprises rotary drum 4 ' and is positioned at the auger conveyor 5 ' of rotary drum, the separation chamber that forms by the inwall of the cylinder body outer wall of auger conveyor 5 ' and rotary drum 4 ', material enters into the separation chamber by charging aperture, because the speed discrepancy of auger conveyor 5 ' and rotary drum 4 ', material is realized Solid-Liquid Separation in the separation chamber.
At present the auger conveyor that extensively adopts of institute mainly is made up of cylindrical end 51 ' and tapering point 52 ' as shown in Figure 1, is provided with screw type blade 53 ' above, and the tapering α of the tapering point 52 ' of auger conveyor 5 ' is invariable (tapering α is about 8 °).This horizontal screw centrifuge that waits tapering, Deng the tapered screw conveyer by blade 53 ' material all permanent shift the top discharging onto from the bottom, the speed no change of middle pusher time, it is wet high to cause final solid formation after Separation of Solid and Liquid to contain, owing to the setting that waits tapering, can not adapt to the requirement of the separating effect of various materials, separating effect is not obvious.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of auger conveyor of taper mutation of the separating effect that can improve material.
The technical scheme that the utility model is taked for achieving the above object is, a kind of auger conveyor of taper mutation, be installed in the rotary drum inner chamber of horizontal screw centrifuge, comprise cylindrical end and tapering point, be provided with the screw type blade by cylindrical end to tapering point on the outer wall of auger conveyor, it is characterized in that: the cone angle of the tapering point of auger conveyor is presented to set up and is put.
Of the present utility modelly further be set to:
Built-up welding has hard alloy layer on the edge of described blade, then spraying plating tungsten carbide coating.Preferably, carbide alloy adopts the W-Co-Ti kind carbide alloy, preferred especially tungsten carbide or titanium carbide.
The beneficial effects of the utility model are as follows:
1, the utility model is by increasing cone angle, the back-flow velocity of liquid is accelerated, when increasing separation back solid-phase material mass dryness fraction, also strengthened the treating capacity of material, by to the method for different material, make various materials all reach optimal separating efficiency with the auger conveyor of the different taperings of fortune.
2, adopt spraying plating tungsten carbide and pile-up welding hard alloy technology on helical blade, 1., improved horizontal screw centrifuge service life have the following advantages:, service life is than long about 5～10 times of common horizontal screw centrifuge, and can use continuously at full capacity for a long time, the production efficiency of Ti Gaoing has reduced cost of investment greatly; 2., because helical blade has high-wearing feature, thereby passing in time, brightization of gap between rotary drum and helical blade is not obvious, directly stablized separating effect preferably, make horizontal screw centrifuge be in high efficiency, high score optimum state for a long time, immeasurable effect has been played in energy-conserving and environment-protective from effect and high stable; 3., horizontal screw centrifuge has been applied in the various fields, increased the range of application of horizontal screw centrifuge.
Below the utility model is described in further detail by the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of original auger conveyor;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of blade described in the utility model.
The specific embodiment
As shown in Figure 2, auger conveyor 5 of the present utility model is installed in the rotary drum inner chamber 4 of horizontal screw centrifuge, comprise cylindrical end 51 and tapering point 52, be provided with screw type blade 53 by cylindrical end 51 to tapering point 52 on the outer wall of auger conveyor 5, the cone angle of the tapering point 52 of auger conveyor 5 is presented to set up and is put.In conjunction with shown in Figure 3, first built-up welding has hard alloy layer 55 on the edge 54 of blade 53, and then spraying plating has tungsten carbide coating 56 again.
Claims (2)
1, a kind of auger conveyor of taper mutation, be installed in the rotary drum inner chamber (4) of horizontal screw centrifuge, comprise cylindrical end (51) and tapering point (52), be provided with screw type blade (53) by cylindrical end (51) to tapering point (52) on the outer wall of auger conveyor, it is characterized in that: the cone angle of the tapering point of auger conveyor (52) is presented to set up and is put.
2, the auger conveyor of a kind of taper mutation as claimed in claim 1 is characterized in that: have the hard alloy layer (55) that built-up welding forms on the edge (54) of described blade (53), and the tungsten carbide coating (56) that forms of spraying plating.
