Abstract
The invention relates to a ceramic reaction kettle mechanical sealing device, which comprises a cooling water tank, a positioning ring, a rubber ripple tube, a spring, a movable ring, a stable ring, a connecting flange, a throttle sleeve and a throttle ring. Wherein, the radial section of rotation axle is segmented sealed; the cooling water tank is sheathed with a positioning ring, a rubber ripple tube, a movable ring, and a stable ring, while one side of water tank has the outlet and inlet of cooling water; the throttle sleeve contains a throttle ring which is screwed into the rotation axle via positioning bolt; the rubber ripple tube is mounted with spring along radius; the concave of rubber ripple tube is mounted with a movable ring to contact the stable ring; the stable ring is embedded into the groove of connecting flange; the cam of stable ring via the compress bolt of compress plate of stable ring is fixed on the connecting flange; the throttle ring is embedded into the throttle sleeve. The invention has tight structure, lower cost, and the application for sealing mechanical device.
Description
Technical field
The present invention relates to the mechanical seal device field, be 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 objective of the invention is problem, provide a kind of mechanical sealing apparatus for enamel reaction still, make it can solve that part is more, assembling procedure is longer, the relative cost technical problems of high to related domain at above-mentioned existence.The objective of the invention 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, be with positioning ring, rubber corrugated pipe, rotating ring and stationary ring in rotating shaft.Side at cooling water tank is offered the cooling water inlet, coolant outlet, and the cooling water inlet is connected by water pipe with coolant outlet; Cooling water plays the effect of the lubricated and cooling of mechanical sealing element.In the throttling ring set, restrictor ring is housed.Positioning ring is screwed in by positioning screwn and is connected with rotating shaft, and rubber corrugated pipe, rotating ring, stationary ring axial displacement are limited.Rubber corrugated pipe spring 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, and rotating ring contacts with stationary ring, and stationary ring is to embed in the groove of adpting flange, produces sealing effect when playing relative friction.The convex shoulder of stationary ring is fixed in adpting flange by the bridge screw of stationary ring pressing plate.Restrictor ring also is to embed in the throttling ring set.The throttling ring set is connected screw with adpting flange by the restrictor ring cover and connects, and restrictor ring is the effect of playing throttling sealing medium and " guide bearing ", and can not be all by its fluid.
The invention solves 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 a structural representation of the present invention.
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 present invention 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.
