Abstract
The utility model relates to the technical field of centrifugal machines and particularly relates to a feed pipe provided with a spiral line inner wall and used on a centrifugal machine. The feed pipe solves the problem of vibration of the centrifugal machine in the material pushing centrifugal machine, resulting from certain impact generated when a material flows by a feed pipe with a smooth inner wall into a rotary drum and is in contact with a high-speed rotating part. The feed pipe comprises a pipe body and is characterized in that the pipe body comprises spiral lines uniformly distributed on the inner wall of the pipe body at the length position from a first connection flange outside a cover to the center of the interior of the rotary drum of the centrifugal machine. The impact of the material on the rotating part is reduced, the vibration of the centrifugal machine is reduced, and the segregation effect is improved.
Description
Technical field
The utility model relates to the centrifuge technical field, relates in particular to a kind of feed pipe with helix inwall that is used on the centrifuge.
Background technology
Pusher centrifuge is a kind of continued operation perforated wall centrifuge, and its operation principle is to utilize rotary drum to rotate at a high speed to produce the powerful centrifugal force and the isolated by filtration effect of screen cloth, makes the solidliquid mixture that is processed reach the purpose of separating and dewatering.The material that needs to separate infeeds centrifuge continuously through feed pipe, by feed distributor material is spread on the first order rotary drum, through screen cloth equably; Most mother liquor here obtains filtering, and is compiled by the liquid collecting hood after export outside the discharge machine, and solid portion is deposited on and forms filter cake on the screen cloth; Not only rotate but also the effect of reciprocating first order rotary drum under, filter cake is pulled in the rotary drum of the second level gradually, makes its positional structure on screen cloth change; And the bigger centrifugal force of acquisition; Because of filter cake has enough time of staying in rotary drum, under powerful centrifugal action, it can reach very low moisture percentage.When filter cake arrives rotary drum exit, the second level, by continuously outside solid collection groove and outlet discharge machine.Feed pipe is the pipe of a common inner wall smooth, and its function just is delivered to rotary drum inside center position with material outside case.When in material flows to rotary drum, contacting, produced certain impact, caused the centrifuge vibration easily, and influenced separating effect with the part of high speed rotary motion.Have though inboard wall of tube body design of the prior art is used, also do not have the organization plan of better elimination vibration for the inside pipe wall of centrifuge feed pipe.Number be a kind of hydraulic giant interior wall construction that washes away earth of CN201546251U like patent announcement, its technical scheme is on the hydraulic giant lumen wall, to be provided with helix, so that in use, current form the high speed rotary water current through hydraulic giant lumen wall helix.And for example patent announcement number is a kind of inner spiral fin tube of CN2864559Y; Its structure is made up of heat-transfer pipe and inner spiral fin stator two parts of being arranged in the heat-transfer pipe, and the inner spiral fin stator in the shape of a spiral the periphery of wire be that soldering is connected with the heat-transfer pipe inwall.
Summary of the invention
The purpose of the utility model is in order to solve pusher centrifuge when the feed pipe of material through smooth inner wall flows in the rotary drum when contacting with the part of high speed rotary motion; Produced certain impact, caused the problem of centrifuge vibration easily, provide a kind of rational in infrastructure; Be used for the feed pipe on the centrifuge with helix inwall; In rotary drum,, reduce the vibration of centrifuge, reach good separating effect with the moving parts direction of rotation charging of rotation at a high speed.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of feed pipe with helix inwall that is used on the centrifuge; Comprise body; It is characterized in that described body comprises the length from outside first adpting flange of case to bowl inside center position, inboard wall of tube body is provided with equally distributed helix.The direction of rotation of helix is pressed the design of bowl direction of rotation; When material in body gets in the rotary drum just along the direction of motion feeding of high speed rotating part; Because the helix in the body is to the commentaries on classics acceleration of prewhirling of material suspended liquid; So will make the smooth-going entering of material change hub and evenly distribution in rotary drum, thereby reduce the vibration of centrifuge.
As preferably, the lead angle Ψ of described helix is 60 °～89 °, and spiral the end of a thread number is single head or bull.Suitable angle guarantees that charging is smooth and easy, and spiral the end of a thread number can be set by the feed pipe specification, and the width of helix need be considered technical parameters such as centrifugal material, treating capacity.
As preferably, described helix is the groove structure on the inboard wall of tube body.The helix preparation method has multiple, and groove structure is that helix directly processes flute profile at inboard wall of tube body.
As preferably, described helix is the bathtub construction that on inboard wall of tube body, is formed by some strip metal lines uniform winding.This processing method is relatively directly easier inboard wall of tube body working groove shape, is welded on metal wire in the smooth body endoporus, by forming flute profile between the metal wire naturally.
As preferably, the groove cross section on the described inboard wall of tube body is rectangular channel or dovetail groove or arc-shaped slot.The helix of various cross sections requires all smoothly smooth and easy in the whole piece feed pipe, does not form the curved point of big resistance, and the fineness of whole inboard wall of tube body is more than or equal to inboard wall of tube body fineness of the prior art.
As preferably, the cross section of described metal wire is rectangle or trapezoidal or circular arc.Different helix grooves adopts difform metal wire welding to constitute.
As preferably, the groove structure cross section that described some strip metal lines uniform winding form on inboard wall of tube body is rectangular channel or dovetail groove or arc-shaped slot.Multiple compound mode is implemented this programme easily in practical application.
The beneficial effect of the utility model is: when material suspended liquid when the feed pipe with helix inwall gets into rotary drum; Through the guide effect of helix, material suspended liquid is produced rotatablely move, reduce the impulsive force of material greatly to rotating part; Reduce the centrifuge vibration, improve separating effect.
