Abstract
The radial sealing device for the movable barrel inlet with hollow feeding shaft includes sealing ring between the inlet with annular slot and the shaft with flange, and the flange of the hollow feeding shaft is embedded into the annular slot to form a labyrinth structure. The V-shaped elastic sealing ring filled into the gap of the labyrinth structure has three sealing surfaces, including bottom plane sealing the hollow feeding shaft and two side surfaces sealing the gap in the labyrinth structure. The present invention has increased sealing surface, and is anticorrosive and low in manufacture cost. The sealing device can prevent leakage of slurry inside the ball mill, and is suitable for wet ball mill.
Description
(1) technical field
The present invention relates to a kind of sealing device of horizontal wet ball mill hollow feed axle feed system.
(2) background technology
The work of wet ball mill is to add an amount of water in process of lapping, solid particle is ground to form the mixture-slurries of certain particle diameter fine powder and water.Wet ball mill have noise little, take up an area of outstanding advantages such as little, reduced investment, dust pollution are little, in the mine, the pulverized coal preparation system extensive use of metallurgy and power station wet desulphurization device.Axial seal is adopted in the sealing of wet ball mill traditionally, and traditional axial sealer is pressed axial restraint and arranged sealing ring, and its advantage is simple in structure, replacing convenience, with low cost; But its shortcoming is also fairly obvious, and is short as withstand voltage low, life-span, change frequently etc., because that the elastic type of itself becomes function is very little, adds the frictional force of sealing system, may cause the wearing and tearing of sealing ring, causes the decline of sealing effectiveness; The most important thing is that when adopting closed cycle to grind system, because wet ball mill recycled pulp liquid measure is bigger, be difficult to guarantee that the wet ball mill inlet does not leak, the result pollutes environment easily.
(3) summary of the invention
The purpose of this invention is to provide a kind of wet ball mill inlet apex combustion seal, solve the sealing problem of hollow feed axle feed system, to solve especially the conventional seals device withstand voltage low, the life-span short, leak, cause easily environmental pollution problems easily.
Technical scheme of the present invention: this wet ball mill inlet apex combustion seal, radially connect hollow feed axle in the movable cylindrical shell of wet ball mill porch, between movable cylindrical shell inlet and the hollow feed axle sealing ring is arranged, it is characterized in that: its hollow feed axle collar is to a flange is arranged, the edge of movable cylindrical shell is a cannelure, in the cannelure of the flange embedding activity cylindrical shell of hollow feed axle, form maze-type structure, in the slit of maze-type structure, be packed into the V-type elastic seal ring, the axial section of sealing circle is V-shaped, the V-shaped depression of V-type elastic seal ring central authorities, three sealing surfaces are arranged, base plane and the sealing of hollow feed axis body, V-type two sides and the sealing of two sides, slit, labyrinth.
The V-arrangement two sides height of above-mentioned V-type elastic seal ring does not wait.
Above-mentioned V-type elastic seal ring is made by nitrile rubber.
Beneficial effect: the structure that the present invention proposes a kind of novel wet ball mill hollow feed axle feed system radial seal, in the maze-type structure between wet ball mill hollow feed axle and movable cylindrical shell, be packed into-the V-type elastic seal ring, the sealing circle is V-shaped, three sealing surfaces are arranged, a V-shaped depression is gone down, and the bottom is the plane, in order to sealed hollow feed axis body.V-type two limits are inequilateral, with two labyrinth inwalls of the sealing of satisfying the demand.This V-type elastic seal ring can be by the pressure of gas in the movable cylindrical shell or liquid (water and slurries) self to the V-type pressurising of caving in, two sealing surfaces at the V-type depression back side are opened all the time, paste respectively and on two sealing surfaces between hollow feed axle and the movable cylindrical shell, and make it stressed even, improve the tightness of sealing surface, enlarged the effective seal area.Movable cylinder internal pressure is big more, and sealing surface pastes and be tight more, and sealing effectiveness is good more.
The present invention is radially installed a circular sealing ring additional in wet ball mill hollow feed shaft, and sealing ring is V-shaped, and material is a nitrile rubber.Utilize the principle that contact-making surface strengthens behind the elastic caoutchouc pressurized, the sealing circle has enlarged the enter the mouth area of dynamic and static sealing surface of wet ball mill, prevents that slurries in the wet ball-milling machine drum body are to external leaks.The radial seal of this wet ball mill inlet can guarantee that wet ball mill can not cause the mixed serum of ore and liquid to the wet ball mill external leakage under bad working environment and in the long time (as a year and a half).
The material that the V-type elastic seal ring adopts is a nitrile rubber, and is corrosion-resistant, manufacturing cost is very low.The present invention is applicable to the wet ball mill sealing of preparation mineral powder slurries, equally also is applicable to the various wet ball mill sealings that prepare mineral powder by solid block, granular ore, as pulverized coal preparation systems such as mine, metallurgy, construction material manufacturing and power station wet desulphurizations.
(4) description of drawings
Fig. 1 is a wet ball mill inlet apex combustion seal position view;
Fig. 2 is the auspicious figure in A place of Fig. 1, and the V-type elastic seal ring is the shape under the nature of pressurized not;
Fig. 3 is the auspicious figure in A place of Fig. 1, and the V-type elastic seal ring is the shape under pressured state.
(5) specific embodiment
Embodiment is referring to Fig. 1,2,3, this wet ball mill inlet apex combustion seal, radially connect hollow feed axle 2 in the movable cylindrical shell of wet ball mill 1 porch, between movable cylindrical shell inlet and the hollow feed axle sealing ring is arranged, its hollow feed axle collar is to a flange 4 is arranged, the edge of movable cylindrical shell is a cannelure 5, in the cannelure of the flange embedding activity cylindrical shell of hollow feed axle, form maze-type structure, in the slit of maze-type structure, be packed into V-type elastic seal ring 3, the axial section of sealing circle is V-shaped, the V-shaped depression of V-type elastic seal ring central authorities has three sealing surfaces, base plane and the sealing of hollow feed axis body, V-type two sides and the sealing of two sides, slit, labyrinth, the V-arrangement two sides height of above-mentioned V-type elastic seal ring can not wait.Above-mentioned V-type elastic seal ring is made by nitrile rubber.
When wet ball mill remained static, the V-type elastic packing was in the state of representing among Fig. 2; When the wet ball-milling machine drum body had just started, the gas in the cylindrical shell can play the effect into step-down in the movable cylindrical shell by discharging in the maze-type structure between hollow feed axle and the movable cylindrical shell.
After the running steadily of wet ball-milling machine drum body, the V-type elastic packing is in the pressured state of representing among Fig. 3, makes equipment be in intact sealing state.
In certain engineering practice, a wet ball mill 2700 * 5400 is arranged, and (φ * L) formerly is designed to axial seal.After the operation, leakage rate is bigger between the wet ball mill feed pipe dynamic and static ring, and the trend of increasing was arranged after operation a period of time.According to the principle of Fig. 2, Fig. 3, the inventor has designed wet ball mill inlet apex combustion seal, and internal diameter of the seal ring is of a size of φ 400, changes after the novel sealing, has stopped leakage immediately, through operation in a year, does not leak yet.
