Abstract
The utility model relates to a grinding roll used for grinding on roll grind pulverizers. The grinding roll is composed of a grinding roll sleeve, a grinding roll core, a grinding roll shaft, a tip press cap and a clamp nut. Connecting structures with parallel installing tapers are equipped between the inner hole of the grinding roll core and the grinding roll shaft, and between the outer circle of the grinding roll core and the grinding roll sleeve. The connecting angle of taper of the latter is bigger than that of the former. The clamp nut at one end of the grinding roll shaft tightly presses the grinding roll sleeve on the grinding roll core through the tip press cap and drives the grinding roll core to tightly press on the grinding roll shaft simultaneously, which makes all the parts of the grinding roll be assembled together. When the grinding roll is worn, the user only needs to change the grinding roll sleeve. The utility model has the advantages of convenient repair, material saving and reasonable structure.
Description
Technical field the utility model relates to a kind of grinding roller that is used for the roller flour mill of grinding material
The background technology roller flour mill generally has 3～5 grinding rollers and a bull ring, and grinding roller is made up of bistrique, grinding roller axle, clamp nut etc.Bistrique is having on the grinding roller axle of certain taper as an integral installation, and compresses with clamp nut.In the course of work, bistrique rotates and presses to bull ring with certain pressure, and material is fed between bistrique and the bull ring, and by grinding, bistrique and bull ring also will be worn simultaneously under the pressure effect between bistrique, bull ring.Because the material at two ends can outwards be overflowed in pressurized process on the bistrique axis direction, therefore the suffered pressure in bistrique two ends is lower, it is less to wear and tear, and the material in the middle of the bistrique is owing to can't outwards overflow, therefore the pressure in the middle of making is much larger than the pressure at two ends, mill efficiency causes the wearing and tearing of bistrique middle part also bigger also far above two ends.Through the use of certain hour, recessed in the middle of the bistrique profile will become like this, the two ends projection.This shape develops into to a certain degree, thereby the mill efficiency that seriously reduces flour mill is made the bistrique premature failure, needs to change bistrique for this reason.Therefore change bistrique and on the one hand will cause bigger waste because the bistrique overall wear is less this moment, on the other hand because bistrique is comparatively heavy, so also very inconvenience of installing/dismounting.
The summary of the invention the purpose of this utility model will provide a kind of like this grinding roller exactly, and it can solve problems such as in use existing waste of material of aforesaid grinding roller and installing/dismounting inconvenience effectively.
The purpose of this utility model is achieved in that grinding roller is made up of grinding roller cover, grinding roller core, grinding roller axle, end gland and clamp nut etc., between grinding roller in-core hole and the grinding roller axle and between grinding roller core cylindrical and the grinding roller cover for having axle, the hole connection structure of equidirectional tapering, and the latter's connection taper angle is greater than the former, the clamp nut of grinding roller axle one end is pressed on the grinding roller cover on the grinding roller core by the end gland, drive the grinding roller core simultaneously and be pressed on the grinding roller axle, thereby make the grinding roller parts be assembled into one.The grinding roller cover is worn in the use, proceed to the shape of the curve shown in Fig. 1 (7) when wearing and tearing after, need change the grinding roller cover.At this moment, since the taper angle between grinding roller core cylindrical and the grinding roller cover greater than grinding roller in-core circle and spool between taper angle, so the self-locking performance that cooperates between the former two faces will be lower than the latter, therefore, after unclamping clamp nut, the grinding roller cover will unload from the grinding roller core easilier.At this moment, the grinding roller cover that more renews is tightened clamp nut, and grinding roller can work on.Like this, grinding head core can use repeatedly, each replacing grinding roller cover that only needs.
According to the character and the apparatus operating parameters of institute's abrasive dust body material, be connected tapering between 1: 50～1: 5 between grinding roller in-core hole and the grinding roller axle, be connected tapering between 1: 25～1: 4 between grinding roller core cylindrical and the grinding roller cover.
Because grinding roller is enclosed within serious wear in the course of work, power also will have certain impact simultaneously, therefore, hardness and toughness to the grinding roller cover all have higher requirement, and particularly grinding roller cover inner surface will be processed, for this reason, requiring the very high occasion of wearability, the grinding roller cover adopts the bimetal composite casting structure, and internal layer is the roller shell core, and skin is a wearing layer.
The utility model is by becoming original whole bistrique the combination grinding roller of being made up of the grinding roller core of grinding roller cover and double tapered, need the weight of removable parts to reduce greatly after making grinding roller wear and tear at every turn, this has reduced the consumption of material on the one hand, has also made things convenient for the maintain and replace of grinding roller on the other hand.Owing to be the tapering syndeton also, the grinding roller core also is very easy to unload from the grinding roller axle when needed simultaneously, and this has simplified the structure of grinding roller axle, therefore the utlity model has very significantly advantage.
Description of drawings is further described the utility model below in conjunction with drawings and Examples.
Figure 1 shows that concrete structure of the present utility model and embodiment.
Figure 2 shows that another embodiment of the utility model.
Among Fig. 1,1 is the grinding roller cover, and 2 for grinding roller overlaps the groove of establishing for the minimizing processing capacity on the endoporus, and 3 is the grinding roller core, and 4 is the grinding roller axle, and 5 is the end gland, and 6 is clamp nut, and 7 is the general shape after the wearing and tearing of grinding roller cover outer surface.
Among Fig. 2, grinding roller cover 1 is made up of two parts, and 1-1 is that grinding roller overlaps outer composite abrasion resistance material, and 1-2 is that grinding roller overlaps compound inner core, and all the other all sequence numbers are identical with Fig. 1.
The specific embodiment is in Fig. 1, earlier grinding roller core (3) is installed on the grinding roller axle (4), again grinding roller cover (1) is installed on the grinding roller core, put end gland (5), tighten clamp nut (6), then clamp nut is pressed on the grinding roller cover on the grinding roller core by the end gland, drives the grinding roller core again and is pressed on the grinding roller axle.The inside and outside double tapered structure of grinding roller core can guarantee to connect reliably between grinding roller axle, grinding roller core, the grinding roller cover three when grinding roller rotates, and does not rotate mutually.After the grinding roller cover may wear to certain degree and need change, unclamp fastening nut, the grinding roller cover to be laid down, the grinding roller cover that more renews is tightened clamp nut, promptly finishes the replacing of new grinding roller cover.
Among Fig. 2, grinding roller cover 1 is the bimetal composite casting structure, and this part is made up of two parts, and grinding roller overlaps wear-resisting outer shroud (1-1) and grinding roller overlaps compound inner core (1-2), outer shroud adopts good material of anti-wear performance such as rich chromium cast iron etc., and inner core employing hardness is low, the material such as the structural carbon steel of good toughness.Both adopt the production of casting combination process, and faying face is metallurgy and mechanical bond.
