Abstract
The utility model discloses a kind of grinding roller main shaft of raymond mill, by section at the bottom of main shaft top cap thread, main shaft bullet, collar bush wear-resistant sleeve stage casing and collar bush alloy sheath, formed, at position, collar bush wear-resistant sleeve stage casing, be compounded with one deck wear-resistant sleeve.This wear-resistant sleeve is injection molded by the injected plastics material of high temperature resistant, wear-resisting and flexibility, and car system is to certain thickness.The injection moulding repeatedly of the utility model grinding roller main shaft, car system, use, greatly reduce the cost of changing grinding roller main shaft, and good seal performance; reduced because of spindle abrasion blow-by; thereby damage bearing, shuts down the number of times overhauling, and has improved the service efficiency of raymond mill.
Description
Technical field
The utility model relates to a kind of grinding roller main shaft, the concrete grinding roller main shaft that relates to a kind of raymond mill.
Background technology
Raymond mill is a kind of a kind of abrasive dust equipment that is applicable to the industry large usage quantities such as mining industry, building materials, chemical industry, metallurgy, between product grading 30-600 order, can regulate, and specific (special) requirements fineness requirement can be ground to 1500 orders.According to the difference of grinding roller number, be divided into several models such as 3r Raymond mill, 4r Raymond mill, 5r Raymond mill, complete machine is stereochemical structure, floor space is little, and systematicness is strong, from raw-material roughing to being delivered to powder process and last packing, can have an independently production system of one's own, finished powder fineness is even.During work, the feed hopper of the material slave case side that needs are pulverized adds in machine, relies on and is suspended on the Burnisher apparatus on main frame plum blossom frame, around vertical axis revolution, own rotation simultaneously.Due to the effect of when rotation centrifugal force, grinding roller outwards swings, and presses in bull ring, makes perching knife scoop up material and delivers between grinding roller and bull ring, because the rolling compaction of grinding roller reaches the object of comminuting matter.Visible according to operation principle; grinding roller main shaft is very crucial and is again parts easy to wear; although can grinding roller main shaft be refueled and be maintained at ordinary times; but more easy to wear, grinding roller main shaft is easy to wear, needs to shut down to change; easily cause again the wearing and tearing of grinding roller hollow shaft simultaneously; and after two component wears, can not repair use again, have to scrap processing, thereby increase production cost.Shut down and change grinding roller main shaft, grinding roller hollow shaft and mill shaft hollow axocoel inner bearing, also reduced the production efficiency of raymond mill.
Summary of the invention
The purpose of this utility model is to provide a kind of grinding roller main shaft of raymond mill, and the grinding roller main shaft that has solved existing raymond mill is easy to wear, and causes the wearing and tearing of grinding roller hollow shaft, and then damages a difficult problem for bearing.Solved frequent replacing parts increases production cost simultaneously, reduces the low defect of raymond mill production efficiency.
In order to address the above problem, the utility model has adopted following technical scheme: a kind of grinding roller main shaft of raymond mill, by section at the bottom of main shaft top cap thread, main shaft bullet, collar bush wear-resistant sleeve stage casing and collar bush alloy sheath, formed, it is characterized in that: the bottom in section top and collar bush wear-resistant sleeve stage casing is compounded with one deck wear-resistant sleeve at the bottom of collar bush alloy sheath.
The grinding roller main shaft of described a kind of raymond mill, is characterized in that: the length of wear-resistant sleeve is 50-90mm, and the thickness of wear-resistant sleeve is 5-10mm, and the material of wear-resistant sleeve is injected plastics material high temperature resistant, wear-resisting and tool flexibility.
The beneficial effects of the utility model: the one, the grinding roller main shaft of the raymond mill of scrapping is repaired, and reused, reduced production cost; The 2nd, the grinding roller main shaft of the raymond mill after repairing is more wear-resisting, sealing is better than the main shaft of not repairing, reduced and shut down the number of times of grinding roller main shaft, grinding roller hollow shaft and the hollow axocoel inner bearing of grinding roller of changing raymond mill, thereby improved the production efficiency of raymond mill; The 3rd, reduced the labour intensity that workman overhauls; The 4th, reduced the dust pollution causing because of maintenance.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Symbol description in accompanying drawing 1: 1 is main shaft top cap thread; 2 is main shaft bullet; 3 is collar bush wear-resistant sleeve stage casing; 4 is wear-resistant sleeve; 5 is section at the bottom of collar bush alloy sheath.
Specific embodiment
As shown in Figure 1, raymond mill grinding roller main shaft forms by four sections, and the section on earth from top, is followed successively by section 5 at the bottom of main shaft top cap thread 1, main shaft bullet 2, collar bush wear-resistant sleeve stage casing 3 and collar bush alloy sheath.By one section of cylindricality straight carbon steel car system, formed, with one section of cylindricality steel alloy car system also can, but cost has just improved.Wear-resistant sleeve 4 is to be compounded on the wear-resisting stage casing 3 of collar bush with a kind of material injection moulding high temperature resistant, wear-resisting and tool flexibility, and rear car system forms.The length of wear-resistant sleeve 4 and thickness are mainly determined according to sealing demand, and length is generally at 50-90mm, and thickness is generally at 5-10mm.
The utility model is used after wearing and tearing at wear-resistant sleeve 4, main shaft can be pulled down again and is used after injection molding car system again, does not damage former main shaft body, has greatly saved production cost.
The material of the utility model wear-resistant sleeve 4 can have multiple choices, needs only high temperature resistant, wear-resisting and can play preferably sealing function.
Claims (2)
1. the grinding roller main shaft of a raymond mill, by section at the bottom of main shaft top cap thread, main shaft bullet, collar bush wear-resistant sleeve stage casing and collar bush alloy sheath, formed, it is characterized in that: the bottom in section top and collar bush wear-resistant sleeve stage casing is compounded with one deck wear-resistant sleeve at the bottom of collar bush alloy sheath.
2. according to the grinding roller main shaft of a kind of raymond mill described in claims 1, it is characterized in that: the length of wear-resistant sleeve is 50-90mm, the thickness of wear-resistant sleeve is 5-10mm, and the material of wear-resistant sleeve is injected plastics material high temperature resistant, wear-resisting and tool flexibility.
