Abstract
The utility model discloses a reaction kettle sealing device in the technical field of chemical engineering. The reaction kettle sealing device comprises a stirring shaft, a reaction kettle cover, a stuffing box and a mechanical seal component, wherein one end of the stuffing box passes through the reaction kettle cover and extends into the reaction kettle; a self-lubricating shaft sleeve is arranged in the stuffing box; flexible sealing fillers are arranged at the upper part of the self-lubricating shaft sleeve; a flanged lip is arranged at the upper end of the stuffing box; a raised gland is also arranged, and the raised part of the gland extends into the stuffing box for pressing the flexible sealing fillers; and the mechanical seal component is arranged at the upper part of the gland. The gland, the flanged lip of the stuffing box and the mechanical seal component are connected through fastening pieces; and an oil cup is arranged at the upper part of the gland. The self-lubricating shaft sleeve and the sealing material inside the stuffing box have the effects of radial shaft swing stabilization and first-level sealing, and the selected mechanical seal component is designed to be mounted at the upper part of the stuffing box and is connected with the stuffing box to form a whole. Therefore, not only the stability during the rotating process of the stirring shaft can be improved, but also the sealing effect of the stirring shaft is ensured.
Description
Technical field
The utility model relates to a kind of reactor seal arrangement of chemical technology field.
Background technique
A large amount of reactors of various bands stirrings that use are as capital equipment in the Chemical Manufacture, in the production process owing to used a large amount of toxic chemical substances, particularly some chemical substance boiling point is low, volatility is big, the toxicity height, corresponding temperature and pressure etc. is arranged again in process of production, and poisonous and harmful substance and gas are easy to spill along the stirring shaft that rotates.At present the sealing means to the stirring shaft that rotates generally has two kinds, and the one, the Stuffing box sealing; The one, end surface mechanical sealing, there is to a certain degree defective in the both: Stuffing box can not ensure effective sealing; End surface mechanical sealing can not effectively ensure the stability of rotatingshaft, thereby directly influences the working life of a whole set of Sealing and cause leakage.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of good sealing effect, can effectively ensure the reflection still seal arrangement of rotatingshaft stability.
The technical solution of the utility model is:
A kind of still is with stirring double-sealing device, comprise stirring shaft, reflection kettle cover, Stuffing box, mechanical sealing assembly, Stuffing box one end passes the reaction kettle cover, stretch in the reactor, be provided with self lubrication bearing in the Stuffing box, self lubrication bearing top is provided with elastic seal packing, the upper end of Stuffing box is provided with flange, one gland that is convex is arranged, and convex portion stretches into and pushes down elastic seal packing in the Stuffing box, and mechanical sealing assembly is arranged on gland top.
Gland is connected by fastening piece with the flange and the mechanical seal device of Stuffing box.
The top of gland is provided with lubricating cup.
Beneficial effect: still is made up of Stuffing box and selected mechanical sealing assembly two large divisions with the stirring shaft double-sealing device, self lubrication bearing and sealing material are arranged in the Stuffing box, play radially wobbling and the primary seal effect of stable axis, selected mechanical sealing assembly design and installation is on the top of Stuffing box, be linked to be the integral body of a device with Stuffing box, so both improve the stability in the stirring shaft rotation process, also ensured the sealing effect of stirring shaft.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of still is with stirring double-sealing device, comprise stirring shaft 7, reaction kettle cover 10, Stuffing box 1, mechanical sealing assembly 6, described Stuffing box 1 one ends pass reaction kettle cover 10, stretch in the reactor, be provided with self lubrication bearing 2 in the Stuffing box 1, self lubrication bearing 2 tops are provided with elastic seal packing 3, the upper end of Stuffing box 1 is provided with flange 9, one gland 4 that is convex is arranged, and convex portion stretches into and pushes down elastic seal packing 3 in the Stuffing box 1, and mechanical sealing assembly 6 is arranged on gland 4 tops.
In the reactor production process, the volatility toxic gas rises along stirring shaft 7 in the still, enter the bottom that is installed in the Stuffing box 1 on the reaction kettle cover 10, Stuffing box 1 bottom design is equipped with a nonmetal self lubrication bearing 2, it not only can block the rising of most of toxic gas, has also played the effect that stable stirring shaft 7 radially wobbles simultaneously; Nonmetal elastic seal packing 3 is arranged on self lubrication bearing 2, tightly pushed down by metal backup shoe 4, the toxic gas of rising further is blocked again, has also further strengthened the effect of stable stirring shaft 7 diameters of axle to swing simultaneously; Gland 4 can compress the self lubrication bearing 2 of elastic seal packing 3 and bottom by fastening piece 8, plays primary seal and fixation, can serve as the attic base that selected vesselseals assembly 6 and sealing lubricating cup 5 are installed again.Like this, the amount and the pressure of toxic gas that can be by 1 sealing of whole Stuffing box significantly reduce and reduce, and the mechanical sealing assembly 6 that is installed at last on the gland 4 all blocks, and seals fully.
