Description
Technical field
The utility model relates to a kind of ball mill accessory, is specially a kind of ball mill manhole cover.
Background technology
Along with the fast development of Real estate industry, the demand for construction materials such as cement also increases gradually, and ball mill is after material is broken, then carries out the key equipment pulverized, and it is widely used in cement, the production industry such as New Building Materials, refractory material.Main ball mill comprises cylindrical shell, stud with liner plate in cylindrical shell, ball mill barrel rotates with certain rotating speed, abrading-ball is made to be subject to the effect of centrifugal force, frictional force and to be attached on shell liner, after abrading-ball is brought to certain altitude, due to the gravity of self by under throwing, impact comminution and grinding are carried out to the abrasive material of cylinder body bottom.Mill manhole lid is detachable, can check inner workings for people after dismounting, existing mill manhole lid structure is perfect not, after mill manhole lid is closed, due to and grinding machine body between gap length up and down the same, cause steel ball easily to snap in gap, when dismantling mill manhole lid, sledgehammer more strikes, it is tighter that steel ball snaps in gap, remove labour intensity very high, thus indirectly add cost, have impact on overall operating efficiency, waste time and energy.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides that a kind of structure is simple, practical, four sides of mill manhole lid are rectangular surfaces, mill manhole lid for convenience detach.
To achieve these goals, the technical solution adopted in the utility model is: a kind of ball mill manhole cover, it comprises port lid body, four sides of port lid body are rectangular surfaces, port lid body are provided with connecting hole and locating dowel, and connecting hole is through institute's port lid body, connecting hole and locating dowel all in pairs linea angulata are arranged, port lid body is also provided with arc handgrip, and arc handgrip is fixedly connected on port lid body, and port lid body surface is also provided with alloy wear-resisting layer.
Further, described port lid body adopts potassium steel material;
Further, the quantity of described arc handgrip is two;
Further, described connecting hole quantity be two;
Further, the quantity of described locating dowel is two.
The beneficial effects of the utility model are: four sides of port lid body are rectangular surfaces, port lid body is provided with connecting hole and locating dowel, connecting hole is through institute's port lid body, connecting hole and locating dowel all in pairs linea angulata are arranged, port lid body is also provided with arc handgrip, arc handgrip is fixedly connected on port lid body, and port lid body surface is also provided with alloy wear-resisting layer, provides that a kind of structure is simple, practical, four sides of mill manhole lid are rectangular surfaces, mill manhole lid for convenience detach.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model using state schematic diagram.
In figure: 1, port lid body, 2, rectangular surfaces, 3, connecting hole, 4, locating dowel, 5, arc handgrip.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1-2, a kind of ball mill manhole cover, it comprises port lid body 1, four sides of described port lid body 1 are rectangular surfaces 2, port lid body 1 are provided with connecting hole 3 and locating dowel 4, and connecting hole 3 is through described port lid body 1, connecting hole 3 and locating dowel 4 all in pairs linea angulata are arranged, port lid body 1 is also provided with arc handgrip 5, and described arc handgrip 5 is fixedly connected on port lid body 1, and described port lid body 1 surface is also provided with alloy wear-resisting layer.
When ball mill manhole cover observation inner workings opened by needs, only need to unload the bolt in connecting hole 3, with polishing door sledgehammer rattle balls mill manhole lid gently, because four sides of port lid body 1 are rectangular surfaces, so the gap between the side of port lid body and ball mill body increases from outside to inside gradually, even if there is a lot of steel ball, steel ball snaps in inner space, also can very fast falling under the vibrations of polishing door sledgehammer, can not strike tighter and tighter, steel balls etc. snap in after thing falls, hold the bowhandle that mill manhole covers, ball mill manhole cover will easily be opened, while time saving and energy saving, indirectly improve operating efficiency, connecting hole 3 and locating dowel 4 all in pairs linea angulata are arranged, and bolt can be directly fixed on ball mill body by connector, adds steadiness when ball mill manhole cover closes, safe and convenient.
The technical scheme that the utility model is optimized further, described port lid body 1 adopts potassium steel material.
The technical scheme that the utility model is optimized further, the quantity of described arc handgrip 5 is two.
The technical scheme that the utility model is optimized further, the quantity of described connecting hole 3 is two.
The technical scheme that the utility model is optimized further, the quantity of described locating dowel 4 is two.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
