Abstract

The utility model belongs to a component of cottonseed delinting and selecting processing equipment. A frame-type drum for centrifugal machine features that the drum bottom and drum are divided into two bodies, which are connected by screw bolt and nut, the frame of drum is composed of 9 axial ribs uniformly distributed on circumference, four reinforcing flange plates in radial direction, connecting flanges at both ends, and the main ribs and flanges of frame are welded together. The utility model has the advantages of changing the round hole of the original rotary drum single hole into the arc-shaped long hole, expanding the area by 21.7 times, thoroughly solving the problem of pile accumulation, being capable of being continuously used for a long time, further improving the separation effect, balancing and consistent, simpler operation process, further improving the production capacity, reducing the cost and saving the maintenance cost.

Description

Centrifuger frame type rotor

The utility model belongs to the parts of the selected process equipment of cottonseed delinting.

From the cotton seeds metering-type cotton seed dilute sulfuric acid processing line that the U.S. introduces, be not with centrifuge, Chinese patent 92236786.8

With homemade WH-800 chemical industry special centrifugal machine, make its suitable cotton seed dilute sulfuric acid lint needs through improvement, become cotton seed dilute sulfuric acid lint special centrifugal machine.But former rotary drum is the overall structure that the foundry goods drum end and plate drum barrel are welded into.For parting liquid is thrown away; on drum barrel, be drilled with 432 apertures in an orderly manner; the drum inwall is equipped with the combined type screen cloth; rotate with rotary drum; gapped between screen cloth and the drum inwall; the atresia place forms the enclosed area, many places, and this space does not have high-speed separation liquid and washes away, and easily gathers the cotton of short staple in the parting liquid; the short flannel that gathers after the work long period hardens; and progressively dwindle the area of hole for back flow, and make the cotton seed wettability slowly rise, influence the even running of production line; need this moment to shut down to clear up; work is interrupted, and the partial shell of the teardown of engine influences the sealing of this part and the life-span of connecting piece simultaneously.

The purpose of this utility model is the long-pending suede problem that solves between former rotary drum screen cloth and the drum inner wall, changes the rotary drum drum into frame-type, is convenient to change.

The purpose of this utility model is to realize like this.

A kind of centrifuger frame type rotor, it is characterized by the bulging end 8 and drum barrel 9 and be divided into two bodies, connect with bolt 7 and nut 10, the drum barrel framework is that 9 axial main muscle 13 are distributed on the circumference, radially be four reinforcing flange sheets 11, two ends are coupling flange 12, and the parts master muscle of framework and flange adopt and be welded.The material of rotary drum comprises that bolt is 1Cr18Ni12Mo2Ti.

Advantage of the present utility model: change the circular hole of former rotary drum single hole into long arc-shaped holes, enlarged areas 21.7 times, thoroughly solved long-pending suede problem, can use continuously for a long time; Separating effect further improves, and is balanced consistent; Operating process is more simple; Production capacity further improves, and cost descends; Save maintenance cost.
