Abstract

The utility model discloses an inlay type roller which comprises a roller body, wherein the periphery face of the roller body is provided with an outer roller face with a module of a concave die in an inlay mode. The utility model has the advantages that the technical scheme that the periphery face of the roller body is provided with the module of the concave die in an inlay mode so as to form the outer roller face is adopted; therefore, when the concave die is deformed after use, only the module at the wearing position needs replacing; the whole roller does not need replacing; the module can also be made of high temperature-resistant and wear-resistant ceramic materials in order to prolong the service life of the module; the integral disability rate of the roller is reduced, the charge against revenue of manufacturers is saved and the labor intensity of repairing workers is reduced. Simultaneously, radiating through holes are arranged between the periphery face of the roller body and the combining face of the module in the axial direction, and gaps exist between the lower parts of two adjacent modules, therefore the radiating effect of the roller in the work is improved and the service life of the roller is further prolonged.

Description

Inserted roll

Technical field

The utility model relates to roller briquetting machine, especially relates to the inserted roll of roller briquetting machine.

Background technology

At present granular material such as coal dust etc. is rolled into required various lump materials, the general roll that adopts is the bulk metal structure, promptly offer the die of different shape at the rolling as required material of the outer peripheral face of metal roll body, move toward one another by a pair roller, bulk material is rolled into lump material, after the roll of this structure uses a period of time, the die formation abrasion of roller surface, roll is scrapped with regard to integral body, reason is frequently changed the expenses that roll has not only increased manufacturer thus, has also increased maintenance personal's the amount of labour simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of cost inserted roll low, easy to maintenance at above-mentioned existing in prior technology deficiency.

For achieving the above object, the utility model can be taked following technical proposals:

Inserted roll described in the utility model, it comprises roll body, is provided with the outer roll surface that one deck is made up of the module that has die at the outer peripheral face of described roll body with mosaic mode.

Between described roll body outer peripheral face and module faying face, be provided with the heat radiation through hole vertically.

Have the gap between the bottom of described adjacent block.

Described module is for axially to be provided with along roll body; Offer groove respectively on two horizontal end faces of each module, be respectively arranged with the locating ring compact heap at described roll body two ends, described locating ring compact heap is provided with and the corresponding alignment pin of described groove.

Advantage of the present utility model is to have adopted technique scheme, thereby the outer peripheral face at roll body is provided with roll surface outside the module formation that has die with mosaic mode, after causing the die distortion through use, the module that need only change the wearing and tearing die gets final product, and does not need to change whole roll like this; In order to increase the service life of module, module can also adopt high temperature resistant, anti abrasive ceramic material to make, and has reduced the whole scrappage of roll, has saved the expense expenditure of manufacturer, has reduced the labour intensity of service worker.Simultaneously owing between roll body outer peripheral face and module faying face, be provided with the heat radiation through hole vertically, and have the gap between the bottom of adjacent block, therefore, improve roll radiating effect at work greatly, and then further prolonged the service life of roll.
