Description
Technical field: the utility model relates to axle sealing structure, particularly a kind of shaft sealing multiple-protection device.Can be applicable to the equipment of use chemical fluid media such as machinery, metallurgy, chemical industry.Play and isolate of the erosion of chemical flowing medium, guarantee the lubricating grease effect, prolong the working life of bearing the bearing support sealing.
Background technique: flat cold-rolled sheet factory degreasing unit electrolytic bath turning roll bearing support is installed on the outer memorial archway of cell body, for preventing chemical flowing medium overflow in the cell body, turning between turning roll cell body and bearing support installed a fixed cover on the roll shaft, it is fastened on the memorial archway support; Leather sheath is installed on cell body and fixed cover is stoped liquid flooding.But owing to have the gap between fixed cover and roll shaft, when turning roll ran up, along with the lifting of roll axis speed, chemical fluid medium and produce foam and water wave impact made fluid see through leather sheath retainer ring gap along roll shaft and permeates to bearing support.Its result not only makes electrolytic solution enter the inner neutral lubrication fat of bearing support, causes bearing temperature rise, causes equipment downtime, causes economic loss; Also waste electrolyte medium, polluted the unit environment.The sealing material of bearing support and form are improved no actual effect owing to limited by bearing block structure.
Summary of the invention: the purpose of this utility model provides a kind of shaft sealing multiple-protection device of sealability excellence.Mainly solve the technical problem that the chemical fluid medium leaks along roll shaft.The technical solution of the utility model is: a kind of shaft sealing multiple-protection device, comprise the shaft sealing preventer body that has through hole, position in shaft sealing preventer body through-holes is mounted with axle sleeve, has one group of reinforced seal of installing face-to-face at least, in the middle of the reinforced seal collection vane is being set face-to-face, also having at least more than one skew back through hole on shaft sealing preventer basis is communicated with the collection vane, skew back through hole external compressed air, the preventer body is made vertical fixing by screw by connecting bolt assembly and unit memorial archway or other position of unit.
The collection vane has a plurality of above uniform radial direction through hole along peripheral direction, processes circumferential groove on the collection vane periphery, and circumferential groove cooperates formation to store up vane with shaft sealing preventer body through-holes.The preventer body is installed the end-face hole of reinforced seal and is takeed on the through hole that has more than 2, is convenient to the reinforced seal dismounting.
Shaft sealing multiple-protection device is provided with the centering regulating mechanism, comprises positioning block, dovetail pressing plate, dovetail movable positioning plate, and positioning block is arranged on the axle sleeve both sides, is fixed on the preventer body with socket head screw; The dovetail pressing plate is fixed on the preventer body with the dovetail bridge screw; The dovetail movable positioning plate connects the adjusting screw slide block with interior hexagonal fastening screw trip bolt; Dovetail movable positioning plate adjusting screw passes the adjusting screw slide block and locating stud, nut shim, pad make up; The dovetail movable positioning plate is installed in the dovetail pressing plate, the state of rest location of axle and the gap of axle rotation are adjusted in the advance and retreat control of preventer body screw thread by dovetail movable positioning plate adjusting screw, the dovetail movable positioning plate plays reinforced seal in the shaft sealing barrier device under static state do not have monolateral stressed effect.
The beneficial effects of the utility model are to have improved the sealability of roll shaft circumferential surface by the installation reinforced seal.At first because the collection vane has been installed, making full use of pressurized air applies positive pressure by a plurality of radial direction through hole on the circumference in the collection vane to the roll shaft surface and (processes circumferential groove on the collection vane periphery, cooperate generation storage vane with the protective equipment through hole), make the aperture and the roll shaft of collection vane keep appropriate gap, play two important function: 1. allow the lip of the interior reinforced seal of sealing configuration protective equipment be expansion state, remain pressure to roll shaft, make the lip rubber of reinforced seal keep sealing to contact with roll shaft all the time, improve the usability of reinforced seal.2. utilize pressurized air cooling reinforced seal material surface, reduce defibrator process and wipe.Secondly, in the sealing structural shielding device, pressurized air can play following effect: 1. pressurized air keeps the positive pressure to the leak free 0.15Mpa of reinforced seal in the sealing configuration protective equipment, prolongs the working life of reinforced seal; 2. when a reinforced seal was lost efficacy owing to wearing and tearing, pressurized air can send through the reinforced seal gap and utter long and high-pitched sounds, and produces and reports to the police.But heighten compressed air pressure by pressure regulator valve and come the outside axial dispersion of block fluid medium this moment, owing to also have a reinforced seal to exist in the shaft sealing protective equipment, this moment, the seal action of protective equipment was still effective.Once more, adjust structure, guaranteed that reinforced seal under static state is not subjected to monolateral pressure and unit that Vertical location is installed owing in shaft sealing multiple-protection device, designed centering.
