Abstract
The utility model relates to a centrifuge, in particular to a discharge device of an outer drum of a novel centrifuge, and mainly solves the technical problems that a discharge hole adopted by the drum of the centrifuge in the prior art is complex in structure and low in discharge efficiency, if the quantity of the discharge holes is increased, the strength of the discharge end of the drum of the centrifuge is reduced, if parts embedded with ceramic sleeves or hard alloy sleeves are adopted, the cost is high, and the processing accuracy requirement is high at the same time. The discharge device comprises a cylindrical section (1) and a conical section (2), and is characterized in that more than three discharge holes (3) are uniformly distributed in the radial direction at the outer end of the conical section (2); one end of each discharge hole is a first plane (4); the other end of each discharge hole is formed by combining a second plane (5) with a folded plane (6); and the distance h between the tangent plane at the lower end of the first plane and the folded plane (6) is 1-3 mm.
Description
Technical field
The utility model relates to a kind of centrifuge, especially relates to a kind of Novel centrifuge outer drum drawing mechanism.
Background technology
The horizontal screw centrifugal seperator be liquid-solid mixture realize continuous separate from one of main separation equipment.The separative efficiency of centrifuge is the centrifuge important performance indexes, and the major measure of existing centrifuge raising separative efficiency is to improve rotary speed to increase separating factor at present, and another kind of measure is to prolong disengaging time to improve separative efficiency.Chinese patent discloses a kind of horizontal spiral centrifuge (publication number: CN 102078844A), it comprises that rotary drum, spiral propeller, differential assembly, pulp-inlet pipe, coupling device, combined vibration-damping base, main motor, auxiliary-motor, slag-drip opening, residue-removing opening, discharging opening, slurry-inlet valve, purge valve, wireless remote sensing device, pulp-water seperating vale, VFC, constant voltage mud overflow valve consist of, and pulp-inlet pipe advances the slurry end and is provided with constant voltage mud overflow valve; The centrifuge slurry output end is provided with the pulp-water seperating vale; Be provided with the combined type vibration damping base between centrifuge and the support ground; Main motor power input is provided with VFC; The VFC front end is provided with the wireless remote sensing device.But the discharge hole structure that this bowl adopts is complicated, discharging efficient is low, be the load of guarantor unit's time, have to increase discharging opening quantity during design, thereby to having reduced the intensity of bowl discharge end, and most critical be traditional drawing mechanism discharging the time Radial resistant force large, consume about 1/10th of main motor power, in order to prevent the discharging opening gauge wear, have to adopt the part of edge ceramic jacket or carbide alloy cover, cost is large, and requirement on machining accuracy is high simultaneously.
The utility model content
The utility model provides a kind of Novel centrifuge outer drum drawing mechanism, it mainly is to solve the discharge hole structure complexity that the existing bowl of prior art adopts, discharging efficient is low, as increase the intensity that discharging opening quantity can reduce the bowl discharge end, as the part that adopts edge ceramic jacket or carbide alloy to overlap, cost is large, simultaneously the high technical problem of requirement on machining accuracy.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: Novel centrifuge outer drum drawing mechanism of the present utility model, comprise cylindrical section and conical section, the outer end radial equipartition that it is characterized in that described conical section has the discharging opening more than 3, discharging opening one end is the first plane, the other end is combined by the second plane and folding face, and wherein the tangent plane of lower end, the first plane is 1-3mm with the distance h of folding face.Drawing mechanism prolongs the tangential flight path of drum inner wall diametric(al) during according to the material discharging, the discharging opening mode that design makes new advances, new discharging opening has milled affects the zone, output section, 1-3mm has on this basis descended again, eliminated the Radial resistant force of material flight, material and rotary drum discharge port end do not come in contact when making discharging, thereby have fundamentally avoided the defective of traditional discharging opening.Discharging opening generally can be set to 4.
As preferably, the tangent plane of lower end, described the first plane and the angle α of conical section middle vertical plane are 10-12o.Angle α the best can be 10.2 o.
As preferably, pass through the arc surface transition between described two planes and the folding face.Discharging is comparatively smooth and easy like this.
Therefore, discharging opening of the present utility model has been eliminated the Radial resistant force of material flight, discharging opening can not worn and not torn, reduce energy consumption 1/10th, need are carried out the enterprise of protein production with centrifuge in enormous quantities, can save a large amount of energy consumptions, reduce other part of output section part such as discharging opening wear-resistant sleeve and the interchangeable carbide alloy cover of discharging opening etc., save 5 percentage points of costs, because material and rotary drum discharge port end do not come in contact during discharging, thereby the mechanical resistance when having reduced discharging has improved discharging efficient, thereby can reduce the quantity of discharging opening, and is simple and reasonable for structure.
