Abstract
The utility model discloses a special measuring tool for abrasion of a grinding roller sleeve and a grinding disc lining tile of a coal mill; the utility model has the advantages that: the accurate data is provided, the parts with larger abrasion are processed in time, the service lives of the roller sleeve and the lining tile are prolonged, a large amount of manpower and financial resources are saved by the roller sleeve and the lining tile which are replaced by welding wire surfacing in a limited abrasion range, the overhaul period is shortened, and time guarantee is won for production.
Description
Technical Field
The utility model relates to an abrasion measuring tool, a special measuring tool of coal pulverizer grinding roller shell, mill lining tile wearing and tearing specifically says so belongs to the abrasion measuring tool field.
Background
The coal mill grinding roller is used as a core component for milling, a roller sleeve and a millstone lining tile mill lump coal under the action of centrifugal force, the roller sleeve and the lining tile are abraded in different degrees along with long-period operation of equipment, contact gaps between the roller sleeve and the lining tile are increased, a coal seam is thickened, the grinding efficiency of the grinding roller is reduced, the milling capacity of the coal mill is influenced for a long time, in order to measure the accuracy of abrasion of the roller sleeve of the coal mill, the later-stage surfacing and maintenance are facilitated, effective and reliable data sources are provided, and accurate measurement needs to be carried out.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to design a special measuring tool of coal pulverizer grinding roller shell, mill lining tile wearing and tearing, simple structure measures accurately, in time handles the great part of wearing and tearing, and then prolongs the life of roller shell, lining tile.
The technical scheme of the utility model is that:
the special measuring tool for abrasion of the grinding roll sleeve and the grinding disc lining tile of the coal mill comprises a first measuring tool and a second measuring tool; the first measuring tool is used for measuring the abrasion loss of the grinding disc lining tile; a first measuring outer arc is arranged on one side of the first measuring tool, the radian of the first measuring outer arc is consistent with that of the inner arc of the lining tile, after the inner arc and the outer arc are tightly attached, the gap which is not attached is the abrasion loss, the gap can be measured by directly using a measuring tape and a steel plate ruler, and the lining tile is determined to be continuously used or replaced according to the size of the measuring gap;
the second measuring tool is used for measuring the abrasion loss of the grinding roller; and a second measuring inner arc is arranged on one side of the second measuring tool, the second measuring inner arc is consistent with the outer arc of the grinding roller, after the inner arc and the outer arc are tightly attached, the gap which is not attached is the abrasion loss, the gap can be directly measured by a measuring tape and a steel plate ruler, and the lining tile is determined to be continuously used or replaced according to the size of the measuring gap.
The first measuring tool and the second measuring tool are provided with handles, so that the measuring tool is convenient to use.
The first measuring tool is made of a steel plate with the length of 470mm, the width of 30mm and the thickness of 3 mm.
The second gauge is made of a steel plate with the length of 510mm, the width of 110mm and the thickness of 3 mm.
The utility model has the advantages that: the accurate data is provided, the parts with larger abrasion are processed in time, the service lives of the roller sleeve and the lining tile are prolonged, a large amount of manpower and financial resources are saved by the roller sleeve and the lining tile which are replaced by welding wire surfacing in a limited abrasion range, the overhaul period is shortened, and time guarantee is won for production.
The present invention will be further explained with reference to the drawings and examples.
Drawings
FIG. 1 is a schematic structural view of a first measuring tool of a special measuring tool for abrasion of a grinding roll sleeve and a grinding disc lining tile of a coal mill according to an embodiment of the present invention;
fig. 2 is a schematic structural diagram of a second measuring tool of the measuring tool special for abrasion of the grinding roller sleeve and the grinding disc lining tile of the coal mill of the embodiment of the invention.
Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.
The special measuring tool for abrasion of the grinding disc lining tile of the coal mill comprises a first measuring tool 10 and a second measuring tool 20;
the first measuring tool 10 is used for measuring the abrasion loss of the grinding disc lining tile, the outer arc 11 of the manufactured outer arc type tool is consistent with the inner arc of the grinding disc lining tile 12, after the inner arc and the outer arc are tightly attached, the gap which is not attached is the abrasion loss, a measuring tape and a steel plate ruler are directly used for measuring the gap, and the lining tile is determined to be continuously used or replaced according to the size of the measured gap.
When in processing, the concrete size of the original millstone lining tile is taken as a standard, steel plates with the length of 470mm, the width of 30mm and the thickness of 3mm are respectively selected and manufactured according to the arc shape of the lining tile, and a hand hole is formed on a measuring tool, so that the use is convenient and the carrying is convenient; the painting and coloring are carried out by black paint, which is not only beautiful and rustless, but also convenient for long-term storage.
The second measuring tool 20 is used for measuring the abrasion loss of the grinding roller, the inner arc 21 of the manufactured inner arc type tool is consistent with the outer arc of the grinding roller 22, after the inner arc and the outer arc are tightly attached, the gap which is not attached is the abrasion loss, the gap can be measured directly by a measuring tape or a steel plate ruler, and the lining tile is determined to be continuously used or replaced according to the size of the measured gap.
When in processing, the specific size of the original grinding roller is taken as a standard, steel plates with the length of 510mm, the width of 110mm and the thickness of 3mm are respectively selected for manufacturing according to the arc shape of the grinding roller, and a hand hole is formed in a measuring tool, so that the grinding roller is convenient to use and carry; the painting and coloring are carried out by black paint, which is not only beautiful and rustless, but also convenient for long-term storage.
