A T-shaped groove is arranged on the drum around a manhole, and a T-shaped bolt for fixing the grinding door is installed in the T-shaped groove. The grinding door is reasonable in structure and convenient to disassemble.
Description
Technical field:
The utility model relates to a kind of mill door form of tube mill.
Background technology:
At present, tube mill is more and more general in sector applications such as cement, metallurgy, chemical industry.In the process of in the past using, the mill door form that adopts is Nei Tishi usually.This structure finds that in actual use effect is still undesirable, and there is defective in structure, the dismounting difficulty.Can drop to the cylindrical shell the inside when dismantling sometimes unless you give your whole attention to it, and smash.And Nei Tishi mill door can make mill door lining specification, kind increase.This all is disadvantageous to liner plate manufacturing and on site spare management.
Another kind of mill door is the enclosing cover formula.The mill door is to be directly connected on the cylindrical shell from the outside with bolt.When this structure is installed and removed, need all be screwed into bolt or withdraw from, very time-consuming.The mill door also falls down easily during dismounting.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the enclosing cover formula mill door of the tube mill of convenient disassembly.
Technical solution of the present utility model is:
A kind of enclosing cover formula mill door of tube mill is characterized in that: comprise the mill door of enclosing cover on the tube mill cylindrical shell, T type groove is set on the cylindrical shell of manhole periphery, the T type bolt of the fixing mill door of dress in T type groove.
Be provided with top wire hole around the mill door closure, bolt is unloaded in mounting or dismounting in the top wire hole.
The utility model is rational in infrastructure, and the mode of fixing mill door is in the manhole periphery T type groove to be set, and with T type bolting mill door, just can tighten bolt or unscrews and unload down as long as twist several ring nuts like this.Be furnished with four screw threads (top wire hole) around the mill door closure, the dismounting of being more convenient for.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of enclosing cover formula mill door of tube mill comprises the mill door 1 of enclosing cover on the tube mill cylindrical shell, and T type groove is set on the cylindrical shell 2 of manhole periphery, the T type bolt 3 of the fixing mill door of dress in T type groove.
Be provided with top wire hole around the mill door closure, bolt 4 is unloaded in mounting or dismounting in the top wire hole.
