Abstract
The utility model discloses an abrasion-resistant outlet protective ring for a vertical spiral discharging centrifuge, and belongs to the technical field of vertical spiral discharging centrifuge equipment. The outlet protective ring is used for coal dehydrating and separating facilities. According to the technical scheme, the outlet protective ring comprises an upper cylinder, a transition section and a lower cylinder which are connected together; through holes and through screw holes are uniformly distributed on the circumference of the transition section; the transition section and the lower cylinder are thickened, and the thicknesses of the transition section and the lower cylinder are 10 to 40 millimeters; and an abrasion-resistant layer is added on the inner surface of each of the transition section and the lower cylinder, an abrasion-resistant material is fully inlaid in the abrasion-resistant layer, and the thickness of the abrasion-resistant layer is 5 to 20 millimeters. The outlet protective ring has the advantages that the thicknesses of the transition section and the lower cylinder are increased, and the abrasion-resistant layer inlaid with the abrasion-resistant material is added on the inner surface of each of the transition section and the lower cylinder, so that the abrasion resistance of the outlet protective ring can be greatly improved, the service life of the outlet protective ring is prolonged, the maintenance workload is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of vertical helical conveyer centrifugal outlet protection ring, belongs to vertical helical conveyer centrifugal equipment technical field.
Background technology
At present, the vertical helical conveyer centrifugal is widely used in the dehydration of coal preparation plant's coal product, has advantages such as floor space is little, product moisture is low, reliable operation, is the key equipment of coal preparation plant's coal dehydration.The vertical helical conveyer centrifugal mainly is made up of transmission device, working portion, casing and lubricating system; Material gets into the space between basket and the spiral through feeding mouth through the cloth awl; Discharge from discharging tube along centrifuge loam cake inflow support with screen cloth through material bed at action of centrifugal force Xia Shui and little particle (centrifugate); Owing between spiral and the basket speed discrepancy is arranged; Pushed to the basket bottom at the inboard coal grain of basket by spiral and export as product through bell-jar and outlet protection ring, this dehydration is continuously carried out.In the centrifuge course of work; The outlet protection ring is used to isolate centrifugate and coal product; Outlet protection ring inboard constantly receives the impact of coal grain and weares and teares, and therefore exports the consumable accessory that protection ring belongs to the vertical helical conveyer centrifugal, just needs at set intervals to change.Replacing outlet protection ring must be removed loam cake, basket, scraper and bell-jar and could accomplish, big, the consuming time length of workload, and therefore improving to improve its service life to the outlet protection ring is the requisite measure of enhancing productivity, reduce maintenance load.
The utility model content
The purpose of the utility model provides that a kind of wearability is better, the vertical helical conveyer centrifugal of longer service life outlet protection ring.
The technical scheme that solves the problems of the technologies described above is:
The wear-resisting outlet protection ring of a kind of vertical helical conveyer centrifugal; It comprises cylinder, changeover portion, following cylinder, and last cylinder, changeover portion and following cylinder link together, even distribution through hole and logical screw on the changeover portion circumference; Its improvements are; Changeover portion has adopted structure thicker with following cylinder, and changeover portion is 10mm-40mm with following cylindrical thickness, has increased wearing layer in changeover portion and following cylindrical inner surface.
The wear-resisting outlet protection ring of above-mentioned vertical helical conveyer centrifugal is covered with high-abrasive material on the said wearing layer, and the thickness of wearing layer is 5-20mm.
The utility model compared with prior art; Advantage has been to increase the most serious changeover portion and following cylindrical thickness of outlet protection ring wearing and tearing; And increased wearing layer in changeover portion and following cylindrical inner surface, and can greatly improve the wearability of outlet protection ring like this, prolong and export protection ring service life; Thereby the minimizing maintenance load is enhanced productivity.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Mark is following among the figure: go up cylinder 1, changeover portion 2, following cylinder 3, wearing layer 4.
Specific embodiments
Show among the figure; The wear-resisting outlet protection ring of vertical helical conveyer centrifugal; Comprise cylinder 1, changeover portion 2, cylinder 3 down, last cylinder 1, changeover portion 2 and following cylinder 3 link together even distribution through hole and logical screw on changeover portion 2 circumference; Through hole is used for the outlet protection ring is connected with support, and logical screw can conveniently export the protection ring dismounting.
In centrifuge work, the outlet protection ring outside contacts with centrifugate, and the inboard of outlet protection ring receives the impact of the coal grain of being released by scraper with certain speed, and the interior lateral wearing that therefore exports protection ring is more serious.Find that through theory analysis and on-the-spot a large amount of investigation cylinder 1 weares and teares hardly on the outlet protection ring, changeover portion 2 and 3 serious wear of following cylinder, the damage of changeover portion 2 and following cylinder 3 causes must change whole outlet protection ring.
Show among the figure that the improvements of the utility model are:
At first, increased the thickness of changeover portion 2 and following cylinder 3, thickening layer is distributed in inner surface, outer surface or the double-sided surface of changeover portion 2 and following cylinder 3.
Secondly, increased wearing layer 4 at changeover portion 2 and following cylinder 3 inner surfaces, be covered with high-abrasive material on the wearing layer 4, wearing layer 4 thickness are 5-20mm.
Above-mentioned improvement can greatly improve the wearability of outlet protection ring, prolongs outlet protection ring service life, thereby reduces maintenance load, enhances productivity.
