Abstract
The utility model discloses a mechanical sealing device for a ceramic reaction kettle, which relates to the field of mechanical sealing devices. The device is mainly composed of a cooling water tank, a positioning ring, a rubber corrugated pipe, a spring, a movable ring, a static ring, a connection flange, a throttling ring sleeve and a throttling ring. The utility model carries out the section seal at the diametral plane of a rotary shaft. The positioning ring, the rubber corrugated pipe, the movable ring and the static ring are sheathed in the cooling water tank. One side of the cooling water tank is provided with a cooling water outlet and a cooling water inlet. The throttling ring is arranged in the throttling ring sleeve. A positioning screw is screwed into the positioning ring to make the positioning ring connected with a rotary shaft. The rubber corrugated pipe is provided with the spring in radical direction. A concave ring of the rubber corrugated pipe is provided with the movable ring. The movable ring makes contact with the static ring which is embedded in a groove of the connection flange. A convex shoulder of the static ring is fixed with the connection flange by a press plate screw of a press plate of the static ring. The throttling ring is embedded in the throttling ring sleeve. The utility model solves the technical problems of more components, long assembly process and relatively high cost. The utility model with compact structure and reasonable design scheme is suitable for the seal of pharmacy and fine chemical devices.
Description
Technical field
The utility model relates to the mechanical seal device field, is applicable to the sealing of pharmacy, fine chemistry industry equipment.
Background technique
At present, the enamel reaction still mechanical sealing element exists the technical problem of two aspects, promptly uses life-span weak point and structural design to owe reasonable.Cause working life short factor a lot, as sealing material select improper, not in place, operation is installed not according to rules; Structural design is to decide with the working condition of equipment operation, and different operating conditions structures should be adjusted at any time.As the ZL patent No. 200420020663.1, " the reactor mechanical sealing element " that disclose is the working condition requirement that can't satisfy reaction at the used simple mechanical Sealing of existing reactor, increase external balance sysmte, realize that fluid medium is under pressure balanced prerequisite, and design constitute the counterrotating end face seal in first road that part such as forward and backward two-stage double seals constitutes by dynamic and static ring, two road end face seals form the spring chamber of sealing, realized that Sealing and cooling water tank fuse, saved a kind of seal arrangement of external balance sysmte.The deficiency of this reactor mechanical sealing element is that part is more, and assembling procedure is longer, thereby relative cost is higher.
Summary of the invention
The purpose of this utility model is the problem at above-mentioned existence, provides a kind of mechanical sealing apparatus for enamel reaction still to related domain, makes it can solve that part is more, assembling procedure is longer, the relative cost technical problems of high.The purpose of this utility model is to adopt following technological scheme to realize.
A kind of mechanical sealing apparatus for enamel reaction still, this device mainly is made up of cooling water tank, positioning ring, rubber corrugated pipe, spring, rotating ring, stationary ring, adpting flange, throttling ring set, restrictor ring, it is characterized in that diametric plane segmented seal, in cooling water tank 1, be with positioning ring 2, rubber corrugated pipe 4, rotating ring 6 and stationary ring 7 in rotating shaft 16.Side at cooling water tank is offered cooling water inlet 14, and coolant outlet 15 is connected by water pipe; Cooling water plays the effect of the lubricated and cooling of mechanical sealing element.Restrictor ring 12 is housed in throttling ring set 11.Positioning ring 2 is screwed in by positioning screwn 3 and is connected with rotating shaft 16, and rubber corrugated pipe 4, rotating ring 6, stationary ring 7 axial displacements are limited.Rubber corrugated pipe 4 spring 5 radially is housed, spring plays the tension force that makes rubber corrugated pipe and supports and whippy effect.Spill ring at rubber corrugated pipe is equipped with rotating ring 6, and rotating ring contacts with stationary ring 7, and stationary ring is to embed in the groove of adpting flange 10, produces sealing effect when playing relative friction.The convex shoulder of stationary ring is fixed in adpting flange by the bridge screw 9 of stationary ring pressing plate 8.Restrictor ring 12 also is to embed in the throttling ring set 11.It is fixedly connected that throttling ring set 11 and adpting flange 10 are connected screw 13 by the restrictor ring cover, and restrictor ring is to play the effect that the throttling sealing medium reaches " guide bearing ", and can not be all by its fluid.
The utility model has solved that part is more, assembling procedure is longer, the relative cost technical problems of high.Compact structure, design proposal are reasonable, are applicable to the sealing of pharmacy, fine chemistry industry equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Sequence number among the figure and title: 1, cooling water tank, 2, positioning ring, 3, positioning screwn, 4, rubber corrugated pipe, 5, spring, 6, rotating ring, 7, stationary ring, 8, the stationary ring pressing plate, 9, bridge screw, 10, adpting flange, 11, the throttling ring set, 12, restrictor ring, 13, the restrictor ring cover connects screw, 14, cooling water inlet, 15, coolant outlet, 16, rotating shaft.
Embodiment
Mode of execution is installed and used with the utility model and is example.Adpting flange 10 is to be connected with the support (base) of enamel reaction still, and it is arranged on the top of enamel reactor, and rotating shaft 16 tops connect motor.Because of support (base), motor all belong to well-known zero parts commonly used, so in Fig. 1, omitted drafting.Behind the installation in position, cooling water inlet 14 connects tap water or circulating pipe, and coolant outlet 15 connects waste pipe, and water is irritated to certain height, and water can be discharged from waste pipe.During driven by motor rotating shaft 16 rotation works done, liquid in the retort or gas will be automatically toward axial air gap leakages, and because of the diametric plane in rotating shaft is provided with restrictor ring 12, gas-liquid and the gas that produces are by throttling.And the rotation of cooling water tank 1 interior rotating shaft 16 also is subjected to the diametric plane of axle, the invasion of axial gas, because of rubber corrugated pipe 4 is heatproof, anti abrasive material, substituted polytetrafluoroethylbellows bellows, in addition rotating ring 6 and stationary ring 7 be with the rotation of rotating shaft 16 do dynamically, relative friction-produced sealing, so reach the demand of pharmacy, fine chemistry industry equipment working condition condition.
