Abstract
A spiral conveyor of a horizontal spiral sedimentation centrifuge comprises a drum and a spiral body, wherein the spiral body is coaxially arranged in the drum and comprises a cylinder and pushing blades; the pushing blades are spirally connected onto the outer circumference of the cylinder; the cylinder comprises a feed end and a clear liquid outlet end; the diameter of the clear liquid outlet end is larger than that of the feed end; a plurality of clear liquid overflow holes are formed uniformly in the cylinder close to the clear liquid outlet end in a circumferential direction and communicated with the inner side and the outer side of the cylinder. A feed liquid enters the drum from a gap between the feed end of the cylinder and the drum, the drum and the spiral body rotate at differential speeds, under the action of centrifugal force field of a feed liquid mixture, heavy phases are separated onto the inner wall of the drum, and light phases are contained on the periphery of the spiral body of the spiral conveyor; and under the action of the differential speeds, the spiral body pushes a solid phase to a solid phase outlet, the clear liquid overflows from a liquid phase outlet, and clear liquid backflow channels are increased by the aid of the liquid outlet end, so that a separated clear liquid can overflow the centrifuge smoothly, and the clear liquid separation efficiency is improved.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the horizontal screw centrifuge of continuous feeding and discharging, particularly a kind of horizontal type screw settling centrifuge auger conveyor.
Background technology:
In prior art, sleeping spiral shell sedimentation conveyer centrifugal carries out in same passage the dehydration of industrial wastewater or sewage and completes, the blade of screw feeder is laid on stack shell on the spot, and waste liquid and separated clear liquid can only be separated by the gap forming between spiral cell body and rotary drum.Because the speed between rotary drum and conveyor screw is poor, cause the stirring of helical blade to filtrate, and reduced separating effect; Meanwhile, clear liquid is by helicla flute overflow, and overflow time lengthens, and overflow ducts is single, and complete machine is processed benefit and reduced.
Summary of the invention:
The purpose of this utility model is to provide a kind of horizontal type screw settling centrifuge auger conveyor, and described this horizontal type screw settling centrifuge auger conveyor will solve in prior art the sleeping spiral shell sedimentation conveyer centrifugal lower technical problem of efficiency of disposing of sewage.
This horizontal type screw settling centrifuge auger conveyor of the present utility model, comprise rotary drum and conveyor screw, described conveyor screw is coaxially arranged in described rotary drum, conveyor screw comprises cylindrical shell and pusher blade, described pusher blade is connected on the excircle of cylindrical shell in a spiral manner, wherein, described cylindrical shell includes a feed end and a purified liquor outlet end, the diameter of described purified liquor outlet end is greater than the diameter of described feed end, on the cylindrical shell of contiguous purified liquor outlet end, be along the circumferential direction evenly provided with the clear liquid spout hole of two above numbers, clear liquid spout hole described in any one is all communicated with cylindrical shell inner side and outside.
Further, described clear liquid spout hole is all the pusher blade starting from purified liquor outlet end on the cylindrical shell between 5 pitch.
Further, the number of described clear liquid spout hole is 4.
Further, the clear liquid spout hole described in any one is the square hole of 15 * 60mm.
Operation principle of the present utility model is: feed liquid enters rotary drum from the gap between cylindrical shell feed end and rotary drum, rotary drum and conveyor screw differential speed rotation, material liquid mixture is under the effect of centrifugal force field, heavy phase is split on drum inner wall, the light conveyor screw periphery that is included in mutually auger conveyor, under the effect of differential mechanism, conveyor screw is constantly pushed solid phase body to solid phase outlet, clear liquid overflows from liquid-phase outlet, clear liquid spout hole has increased clear liquid return flow line, be convenient to separated clear liquid and successfully overflow centrifuge, reduce clear liquid spillage drag, improve clear liquid separative efficiency.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges clear liquid spout hole on the conveyor screw of horizontal type screw settling centrifuge, has increased many clear liquid return flow lines, through experimental test, than the solid phase moisture percentage of traditional horizontal spiral centrifuge separation, reduces more than 5%, and separating effect improves more than 10%.
Accompanying drawing explanation:
Fig. 1 is the structural representation of horizontal type screw settling centrifuge auger conveyor of the present utility model.
Fig. 2 is the radial view of horizontal type screw settling centrifuge auger conveyor of the present utility model.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, horizontal type screw settling centrifuge auger conveyor of the present utility model, comprise rotary drum (not shown) and conveyor screw, described conveyor screw is coaxially arranged in described rotary drum, conveyor screw comprises cylindrical shell 1 and pusher blade 2, described pusher blade 2 is connected on the excircle of cylindrical shell 1 in a spiral manner, wherein, described cylindrical shell 1 includes a feed end and a purified liquor outlet end, the diameter of described purified liquor outlet end is greater than the diameter of described feed end, on the cylindrical shell 1 of contiguous purified liquor outlet end, be along the circumferential direction evenly provided with the clear liquid spout hole 3 of two above numbers, clear liquid spout hole 3 described in any one is all communicated with cylindrical shell 1 inner side and outside.
Further, described clear liquid spout hole 3 is all the pusher blade 2 starting from purified liquor outlet end on the cylindrical shell 1 between 5 pitch.
Further, the number of described clear liquid spout hole 3 is 4.
Further, the clear liquid spout hole 3 described in any one is the square hole of 15 * 60mm.
The operation principle of the present embodiment is: feed liquid enters rotary drum from the gap between cylindrical shell 1 feed end and rotary drum, rotary drum and conveyor screw differential speed rotation, material liquid mixture is under the effect of centrifugal force field, heavy phase is split on drum inner wall, the light conveyor screw periphery that is included in mutually auger conveyor, under the effect of differential mechanism, conveyor screw is constantly pushed solid phase body to solid phase outlet, clear liquid overflows from liquid-phase outlet, clear liquid spout hole 3 has increased clear liquid return flow line, be convenient to separated clear liquid and successfully overflow centrifuge, reduce clear liquid spillage drag, improve clear liquid separative efficiency.
