The mechanical sealing structure has the advantages that the leakage problem of slurry and water is completely solved, the zero leakage is really realized, the cleanliness of site environment is ensured, and the waste problem of limestone is solved, thereby reducing power consumption, facilitating installation and maintenance, reducing maintenance time, and ensuring the operational reliability of a bearing.
Description
Technical field
The utility model relates to a kind of mechanical seal structure that is used for wet ball mill, is used for the sealing between wet ball-milling machine inlet capable and the grinding machine body, prevents to leak, and belongs to the wet ball mill technical field of sealing technology.
Background technique
Before wet ball mill is not installed mechanical seal, there is general leakage phenomenon in the grinding machine inlet, this not only constitutes potential threat to block bearing, and can cause variety of problems, in order to eliminate this defective, at present, packing seal or rubber seal sealing are adopted in sealing between the material feeding mouth of domestic and international most of wet ball mill and the grinding machine body, packing seal is divided into the sealing of adopting the oil immersion asbestos packing and the sealing of adopting PTFE, and the sealing of rubber seal be divided into the band skeleton and not with skeleton.
As shown in Figure 1, be the packing seal structure schematic representation, form that pressure ring 1, first filler 2 and the grinding machine inlet pipe 5 of second filler 3 by grinding mill barrel 4 are connected by pressure ring 1, first filler 2, second filler 3, grinding mill barrel 4 and grinding machine inlet pipe 5.As shown in Figure 2, be the rubber sealing structure schematic representation, form by the wear-resisting Taper Pipe 10 of rubber gasket sheet 6, feeding pipe 7, grinding machine material-receiving device 8, fixed plate 9 and grinding machine, rubber gasket sheet 6 is connected between the feeding pipe 7 of grinding machine material-receiving device 8 and the wear-resisting Taper Pipe 10 of grinding machine by fixed plate 9 and reaches sealing, and all there is significant disadvantages in these two kinds of sealings:
Common shortcoming is: have the leakage of slurries and water, a draining/slurry pipe need be installed, on the ground gutter will be set, the slurries of leakage are difficult to utilize again, so it goes back befouling environment; The slurries that leak from sealing part flow into bearing support and then corrosion bearing easily, produce serious consequence, also cause the waste of the energy in addition.
Other shortcomings of gland sealed are: the filler life-span is short, changes difficulty, can not seal effectively.
Other shortcomings of rubber seal are that caulking gum is perishable, and are aging fast, are non-standard component, need special having made to order, and installation precision is had relatively high expectations.
Because sealing surface has relative rotation, therefore in various encapsulating methods, mechanical seal is a kind of more satisfactory structure, can compensate automatically, but mechanical seal at present never has use on pebble mill, and main cause is:
1) need the size of seal contact face of sealing bigger;
2) structure of spring is bigger, and tension force is difficult to calculate;
3) difficulty, working service inconvenience are installed.
Summary of the invention
The purpose of this utility model provides the leakage problem that a kind of thorough solution pebble mill import exists, thereby reduces the loss of limestone, reduces the pollution of environment, improves the mechanical seal structure of pebble mill utilization ratio.
For realizing above purpose, the technical solution of the utility model provides a kind of mechanical seal structure that is used for wet ball mill, it is characterized in that, comprise cylindrical shell, rotating ring and restrictor ring are located on the grinding mill barrel by Cock screw, and the mechanical sealing static ring that has equal pendular ring is located on the axle sleeve by positioning screwn, between mechanical sealing static ring and axle sleeve, be provided with O shape circle, outside mechanical sealing static ring, be provided with throttling O shape circle, be provided with axle sleeve O shape circle in the axle sleeve inboard, be provided with rotating ring O shape circle and jump ring in the rotating ring inboard.
Described mechanical sealing static ring is made up of ripple spring and cemented carbide wear ring.
The utility model adopts mechanical sealing static ring, mechanical sealing static ring is made up of ripple spring and cemented carbide wear ring, undulatory spring, both solved the inconvenient problem of installing, can carry out good sealing to water again, adjust the tension force of ripple spring length and then adjustment spring by the position of adjusting Cock screw, thereby solved the tensioning problem of mechanical seal, in order to guarantee to seal evenly flowing of water, be provided with equal pendular ring in the mechanical seal device, in addition, at grinding machine material entrance place, be provided with a labyrinth seal shape restrictor ring, to make things convenient for the installation of grinding machine inlet pipe.
The utility model has the advantages that:
1. thoroughly solve the leakage problem of slurries and water, really accomplished zero leakage, guaranteed the cleaning of site environment;
2. thereby the waste problem that has solved limestone has reduced power consumption;
3. convenient for installation and maintenance, reduced the maintenance operation time;
4. guaranteed the reliability of bearing working.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 3, be a kind of mechanical seal structure schematic representation that is used for wet ball mill, a kind of mechanical seal structure that is used for wet ball mill is made up of axle sleeve 11, positioning screwn 12, equal pendular ring 13, O shape circle 14, unit loading type static components 15, axle sleeve O shape circle 16, throttling O shape circle 17, rotating ring 18, restrictor ring 19, the recessed end Cock screw 20 of interior hexagonal, jump ring 21, rotating ring O shape circle 22.
Rotating ring 18 and restrictor ring 19 are installed on the grinding mill barrel 4 by Cock screw 20, rotating ring 18 is made for Hardmetal materials, carry out circumferential location with the two basic points locating stud, prevent counter-rotating, axially fix with back-up ring with the hole, prevent the slurries leakage, the mechanical sealing static ring 15 that has equal pendular ring 13 is installed on the axle sleeve 11 by positioning screwn 12, described mechanical sealing static ring 15 is made up of ripple spring and cemented carbide wear ring, cover upper O-shape ring 14 between mechanical sealing static ring 15 and axle sleeve 11, put throttling O shape circle 17 at mechanical sealing static ring 15, at axle sleeve 11 inboard cover Upper shaft sleeve O shape circles 16, put rotating ring O shape circle 21 and jump ring 22 in rotating ring 18 inboards, sealing is more effective like this.After these work are finished, connect to mechanical seal and go up sealing water, installment work has just all been finished.
During work, in the time of the wet ball mill proper functioning, material (normally limestone) enters grinding mill barrel 4 inside by the grinding machine inlet pipe, grinding machine inlet pipe 5 is motionless, and grinding mill barrel 4 rotates, mechanical sealing static ring 15 is static, rotating ring 18 is for what rotate, and grinding machine is in rotation, and mechanical sealing static ring 15 and rotating ring 18 are understood mutual friction mutually, the material of rubbing surface is wear-resisting cemented carbide, because have sealing water to pass through, therefore, the heat radiation of this rubbing surface is all right, simultaneously because sealing water has certain pressure, so the slurries of grinding mill barrel inside and water and lime building stones can not flow out.This has just solved the leakage problem at relative movement rubbing surface place effectively.
