Abstract
The utility model relates to the field of vertical mills, in particular to a protective structure for a grinding disc central cover plate of a vertical mill, which comprises a grinding disc central cover plate; a plurality of protective side plates for blocking materials are arranged on the central cover plate of the grinding disc. The utility model discloses a protective structure for standing mill center apron, through the wear-resisting protection curb plate of setting up on standing mill center apron, after the mill begins to operate, tiny material can be piled up in mill center apron top because of the effect of protection curb plate in the mill, and then can prevent the direct impact wear that the material blanking in-process caused mill center apron.
Description
Technical Field
The utility model relates to a vertical mill field is a protective structure who is used for vertical mill center apron particularly.
Background
The vertical mill is widely used for grinding raw materials, clinker, slag and the like in cement plants and powder mill plants, belongs to high-efficiency and energy-saving industrial equipment, and has good economic benefit and energy-saving effect. But because the working condition of grinding vertical mill has decided, the lime stone material direct impact mill center apron after the pan feeding can cause the damage of center apron, and then influences the mill operation, so need optimize mill center apron and solve above-mentioned technical problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a protective structure for standing mill center apron.
In order to realize the purpose, the utility model discloses a technical scheme be:
a protective structure for a grinding disc central cover plate of a vertical grinding machine comprises the grinding disc central cover plate; a plurality of protective side plates for blocking materials are arranged on the central cover plate of the grinding disc.
Each protective side plate is an annular side plate.
Four protection side plates are arranged on the grinding disc central cover plate and are distributed at intervals in an annular mode.
The four protective side plates are a first side plate, a second side plate, a third side plate and a fourth side plate, the outer diameter of the first side plate is smaller than the inner diameter of the second side plate, and the outer diameter of the second side plate is smaller than the inner diameter of the third side plate; the third side plate outer diameter is smaller than the fourth side plate inner diameter; the first side plate, the second side plate, the third side plate and the fourth side plate are concentrically distributed.
The first side plate height is greater than the second side plate height.
The annular side plate is fixedly connected with the grinding disc central cover plate.
The utility model has the advantages that:
the utility model discloses a protective structure for standing mill center apron, through the wear-resisting protection curb plate of setting up on standing mill center apron, after the mill begins to operate, tiny material can be piled up in mill center apron top because of the effect of protection curb plate in the mill, and then can prevent the direct impact wear that the material blanking in-process caused mill center apron.
Drawings
The contents of the various figures of the specification and the labels in the figures are briefly described as follows:
fig. 1 is a front view of the present invention.
Fig. 2 is a top view of the present invention.
The labels in the above figures are:
1. the central cover plate comprises a central cover plate 2, a first side plate 3, a second side plate 4, a third side plate 5 and a fourth side plate.
Detailed Description
The following description of the preferred embodiments of the present invention will be made in further detail with reference to the accompanying drawings.
A protective structure for a grinding disc central cover plate of a vertical grinding machine comprises a grinding disc central cover plate 1; a plurality of protective side plates for blocking materials are arranged on the grinding disc central cover plate 1; the utility model discloses a protective structure for standing mill center apron 1, through the wear-resisting protection curb plate of setting up on standing mill center apron 1, after the mill begins to operate, tiny material can be piled up in mill 1 top at mill center apron because of the effect of protection curb plate in the mill, and then can prevent the direct striking wearing and tearing that the material blanking in-process caused mill center apron 1.
Preferably, each protective side plate in the utility model is an annular side plate; annular curb plate structure for form a groove structure between protection curb plate and the mill center apron 1, realization that can be better blocks the material, better formation buffer layer.
Preferably, in the utility model, the central cover plate 1 of the grinding disc is provided with four protective side plates which are distributed at intervals in a ring shape; the four protective side plates are a first side plate 2, a second side plate 3, a third side plate 4 and a fourth side plate 5, the outer diameter of the first side plate 2 is smaller than the inner diameter of the second side plate 3, and the outer diameter of the second side plate 3 is smaller than the inner diameter of the third side plate 4; the outer diameter of the third side plate 4 is smaller than the inner diameter of the fourth side plate 5; the first side plate 2, the second side plate 3, the third side plate 4 and the fourth side plate 5 are concentrically distributed; such setting for mill center apron 1 is separated into a plurality of interval distribution's groove structure, makes things convenient for piling up of material, avoids setting up too much the piling up material of single protection curb plate low-lying department one end simultaneously.
Preferably, in the present invention, the height of the first side plate 2 is greater than the height of the second side plate 3; this makes the groove structure that first curb plate 2 formed can pile up more materials, because the groove structure that first curb plate formed is the region that receives the material impact for a long time, so increase the groove depth that first curb plate encloses, assurance buffering effect that can be better is favorable to prolonging the life of mill.
Preferably, the annular side plate of the utility model is fixedly connected with the central cover plate 1 of the grinding disc; the bolts can be fixedly connected and penetrate through the annular side plate to be connected with the grinding disc central cover plate 1, and can also be connected in a welding mode, preferably, the bolts are connected and can be detached, and subsequent replacement and maintenance are facilitated.
Obviously the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial improvements made by the method concept and technical solution of the present invention are all within the protection scope of the present invention.
