Description

Sealing device for liner plate bolt hole of magnetite ore dressing mill
Technical Field
The utility model relates to a sealing device for a liner bolt hole of a magnetite ore dressing mill, and belongs to the technical field of mechanical equipment in the metallurgical industry.
Background
The mill is the main equipment of the concentrating mill, and is used for crushing ore through steel balls, steel segments and other ore grinding media. The mill mainly comprises barrel, end cover, transmission, motor, feeder etc. wherein the inboard of barrel, end cover needs to install the welt to reduce the wearing and tearing of medium and ore to barrel and end cover, reduce the change number of times, extension equipment's life.
Bolt holes are arranged on the ball mill cylinder and the end cover for fixing the lining plate. After the ball mill is operated, the abrasion of different degrees exists in the use process, part of ore pulp can be thrown out along the defect of the bolt hole or the cylinder body around the bolt hole, the ore pulp continuously flows out, the abrasion is formed on the cylinder body, the service life of the cylinder body is reduced, and the field environment is greatly influenced.
Disclosure of Invention
The utility model aims to provide a sealing device for a liner plate bolt hole of a magnetite ore dressing mill, which has good sealing effect, reduces the throwing-out of ore pulp in the running process of the mill, improves the field environment of the mill and solves the problems in the background technology.
The technical scheme of the utility model is as follows:
a sealing device for a liner plate bolt hole of a magnetite ore dressing mill comprises a mill cylinder body, an end cover and a liner plate, wherein the liner plate is fixed on the cylinder body or the end cover through a liner plate bolt, a rubber lump, a bowl-shaped iron plate and a nut are further arranged on the liner plate bolt, the rubber lump is close to the cylinder body or the end cover, and the nut tightly presses the rubber lump on the cylinder body or the end cover through the bowl-shaped iron plate; the inside of the rubber lump is provided with a magnet ring matched with the lining plate bolt.
Bolt holes matched with the lining plate bolts are respectively formed in the rubber lump and the bowl-shaped iron plate.
One side of the rubber lump, which is close to the bowl-shaped iron plate, is a curved surface matched with the bowl-shaped iron plate.
One side of the rubber lump, which is close to the cylinder or the end cover, is cylindrical.
The size of the magnet ring is matched with the diameter of the lining plate bolt.
According to the utility model, the glue lump with the magnet ring and the bowl-shaped iron plate are sequentially penetrated on the lining plate bolt, and then the nut is fastened on the outer side of the bowl-shaped iron plate, so that the glue lump is tightly pressed on the cylinder or the end cover until part of the glue lump is deformed. After the mill is operated, when partial ore pulp is thrown out along the bolts, magnetite in the ore pulp can be attracted to the surface of the rubber lump due to the existence of the magnet ring, so that the bolt holes are blocked, and the sealing effect is achieved.
The beneficial effects of the utility model are as follows: the sealing effect is good, the throwing out of ore pulp and the abrasion of each place in the running process of the mill are reduced, the field environment of the mill is improved, the service life of equipment is prolonged, the operation rate of the equipment is improved, and the labor capacity of maintenance workers is reduced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
in the figure: bowl-shaped iron plate 1, glue lump 2, magnet ring 3 and bolt hole 4.
Description of the embodiments
The utility model is further illustrated by way of example with reference to the accompanying drawings.
Referring to fig. 1, a sealing device for a liner bolt hole of a magnetite ore dressing mill comprises a mill cylinder, an end cover and a liner, wherein the liner is fixed on the cylinder or the end cover through a liner bolt, a rubber lump 2, a bowl-shaped iron plate 1 and a nut are further arranged on the liner bolt, the rubber lump 2 is close to the cylinder or the end cover, and the nut tightly presses the rubber lump 2 on the cylinder or the end cover through the bowl-shaped iron plate 1; the glue lump 2 is internally provided with a magnet ring 3 matched with a lining plate bolt.
In this embodiment, referring to fig. 1, a bowl-shaped iron plate 1 is made of an iron plate or a steel plate, and is bowl-shaped, a rubber lump 2 is made of rubber, one side of the rubber lump 2, which is close to the bowl-shaped iron plate 1, is a curved surface matched with the bowl-shaped iron plate 1, and one side of the rubber lump 2, which is close to a cylinder or an end cover, is cylindrical. The bowl-shaped iron plate 1 is respectively provided with bolt holes 4 matched with the lining plate bolts, and the size of the magnet ring 3 is matched with the diameter of the bolt holes 4.
When installing the lining board, lining board installers sequentially wear the glue lump 2 with the magnet ring 3 and the bowl-shaped iron plate 1 on the lining board bolts, fasten the lining board bolts on the outer side of the iron bowl 1, tightly press the glue lump 2 on the cylinder body or the end cover until part of the glue lump is deformed.
After the ball mill runs, part of ore pulp can be thrown out along the defect of the cylinder body around the bolt hole, and magnetite in the ore pulp can be attracted to the surface of a glue lump due to the existence of the magnet ring 3, so that the bolt hole and the defect are blocked, and the sealing effect is achieved.
Compared with the prior art, the utility model has the following advantages:
(1) The magnet ore particles are attracted by the magnet ring to block the tiny space, so that the tightness is improved;
(2) The utility model uses magnetic field sealing, and has better sealing effect on the cylinder or end cover with longer service time, unsmooth surface and more defects;
(3) The utility model has better sealing to the bolt hole, can reduce the times of stopping the grinder to fasten the bolt, improve the operation rate of the equipment and increase the yield of a concentrating mill.
