The invention discloses a device for sealing an inlet pipe of an overflow ball mill, which comprises a connecting flange, a horn-shaped sealing gasket, a stressed pad and fixing flanges. The connecting flange is fixedly connected with a flange for the inlet of the ball mill; the inlet pipe is provided with the horn-shaped sealing gasket, the stressed pad and the fixing flanges in sequence; the horn-shaped opening of the horn-shaped sealing gasket faces to the connecting flange; the horn-shaped sealing gasket is made of rubber; the external diameter of the horn-shaped sealing gasket is less than the aperture of a connecting flange and ball mill cross section connection bolt, and the internal diameter matches with the external diameter of the inlet pipe; the fixing flanges are two semicircular connecting components; and at least six stressing and compressing parts are uniformly arranged the circular surfaces of the fixing flanges. The device disclosed by the invention has the advantages of low investment, simple configuration, convenience of installation and obvious effect. Due to the adoption of the device, the site can be kept neat and clean, the labor intensity of the operators on the site and the equipment maintenance time and frequency can be reduced greatly, and the equipment can work stably for a long period and is more convenient to change.
Description
Technical field
The present invention relates to a kind of auxiliary device of mining ball mill, specifically relate to a kind of overflowball mill feed pipe sealing device.
Background technology
Ball mill is one of capital equipment of chemical industry, smelting, mine production; Because ball mill feed pipe and the sealing of mill body lack the effective seal method, cause the interior ore pulp of mill through leaking between feed pipe and the mill body, have a strong impact on the device context management; Strengthen labor intensity of operating staff, the start-stop car is frequent.Because of ball mill moves in a circle when moving, and the feed pipe transfixion must leave enough gaps between the two when being linked and packed; Usually way is that gap location is used rubber bar, and soft materials such as asbestos cord are filled, and two ends are fixed with steel flanges; Play sealing function, but in when operation owing to after the friction, produce the gap again; And packing material can't be eliminated the gap, is that ore pulp leaks through the gap location that the friction back produces in the mill.Ore pulp is fine granularity, strengthens coefficient of friction again, cause leaking increasing, last parking maintenance.Reduce the device capability of overflowball mill greatly, restrict stable, the long-term operation of this equipment.
Summary of the invention
The object of the invention is exactly deficiency and the shortcoming that will eliminate above-mentioned prior art; The device that provides a kind of effective elimination ball mill feed pipe to leak; Field management is dirty, unrest, poor to cause after the leakage of solution ball mill feed pipe; Reduce labor intensity of operating staff, reduce the production technology difficult problem of frequent parking maintenance.
For reaching above-mentioned technique effect; The present invention adopts following technical scheme: a kind of overflowball mill feed pipe sealing device comprises adpting flange, tubaeform sealing gasket, stressed pad and mounting flange; Adpting flange is fixedly connected with ball mill charging aperture flange; On feed pipe, be provided with tubaeform sealing gasket, stressed pad and mounting flange successively, the horn mouth of tubaeform sealing gasket is towards the adpting flange setting.
Preferably, said tubaeform sealing gasket is the rubber material, and external diameter is less than the aperture of adpting flange and ball mill section connecting bolt, and internal diameter and feed pipe external diameter are complementary.
Preferably, said tubaeform sealing gasket is to have the peristome that the loudspeaker bottom that reinforces base ring and thickness gradually approach to horn mouth.
Preferably, the material of said adpting flange is a 16Mn steel high-abrasive material, and roughness is 1.6, and the adpting flange internal diameter is greater than feed pipe 10mm, and both contact setting.
Preferably, said mounting flange is the flexible connection parts of two semi-annular shapes, evenly is provided with at least 6 reinforcings on its anchor ring and presses portion.
Preferably, the reinforcing portion of pressing of said mounting flange is hemispherical protuberances or on anchor ring, directly processes screw through-hole stressed bolt is installed.
Beneficial effect of the present invention:
A kind of overflowball mill feed pipe sealing device disclosed by the invention, small investment, configuration is simple; Easy for installation, effect is comparatively obvious, and is on-the-spot clean and tidy clean; Reduce site operation personnel's labour intensity and overhaul of the equipments time, frequency greatly, guarantee equipment long period, stable operation.According to trumpet type rubber gasket of ball mill feed pipe external diameter design, utilize rubber to have bigger flexible characteristics, make the stressed operation of rubber gasket; Can in time reset after the friction; Stop ore pulp to leak, simultaneously, rubber and steel part junction are soft friction; Can improve service life, and maintenance is changed conveniently.
