Abstract

The utility model discloses a reactor sealing device, which comprises a reactor and a stirrer. The stirrer is mounted on a reactor cover, a ring which is seamlessly fixedly connected with a shaft is arranged on the upper portion of the shaft of the stirrer, an annular groove is disposed below the outer edge of the ring, a drain pipe is arranged at the bottom of the groove, the groove is fixed onto the reactor cover, the surface of the ring is oblique from the inside to the outer edge, and an outlet of the drain pipe is positioned outside the reactor. Leaked water, which is possibly caused by mechanical seal, of the reactor can be drained by the aid of the seamless ring of the stirring shaft and the groove disposed below the ring, chemical reaction safety is further improved, the sealing device is simple and is convenient in installation, the structure of the reactor does not need to be changed, and secondary mechanical seal water leakage protection for the reactor is realized.

Description

A kind of agitated reactor sealing device

Technical field

The utility model belongs to chemical consersion unit design field, especially belongs to a kind of chemical reaction still design field, particularly a kind of sealing device of agitated reactor.

Background technology

Agitated reactor is a common equipment in the chemical process; In order to realize the evenly fully controlled of chemical reaction; Agitated reactor has agitator that reaction mass is stirred usually, and agitator generally is installed in agitated reactor top, stretches into agitated reactor and drives stirring vane through shaft and realize stirring.The agitated reactor shaft is mechanical seal with the contact portion of reaction kettle cover, and mechanical seal is that water cools off.Machinery long-play machine envelope will be leaked unavoidably; Because usually the material in the agitated reactor can not get wet; Water gets into the quality that will have a strong impact on product in the still, so in the agitated reactor equipment of Chemical Manufacture, it is the major issue of agitated reactor structural design that the sealing of solution is effectively stably leaked.

Summary of the invention

The utility model discloses a kind of agitated reactor sealing device according to the deficiency of prior art, and the problem that the utility model will solve provides a kind of shaft leakage-proof structure, effectively solves the influence that shaft sealing is leaked and caused to production.

The utility model is realized through following technical scheme:

The agitated reactor sealing device comprises reaction kettle body and agitator, and agitator is positioned at agitated reactor and covers; In agitated reactor, stirrer shaft top has and the fixing annulus of axle seamless link, and there is annular groove annulus outward flange below; Bottom portion of groove has drainpipe, and groove is fixed on agitated reactor and covers.

Further said annulus surface is edge tilt from inside to outside.

Further said drainpipe outlet is positioned at outside the agitated reactor.

When above-mentioned sealing device is installed, at first made a circle ring disk, annulus has been fixed on an appropriate location, top; Can annulus be connected with axle through no seam welding or alternate manner in the time of fixedly, connect back annulus and shaft connection place and do not seep water, the annulus surface preferably tilts from inside to outside; Annulus outward flange below is provided with a groove receiver and collects the water that gets in the still; Groove receiver and agitated reactor cover bolt are fixed, and groove receiver bottom has pipeline and agitated reactor outside to link to each other, and the pipeline in the agitated reactor has a loose joint; If machine leak sealing water like this; Arrive the groove receiver through annulus when water gets into agitated reactor, discharge agitated reactor through the pipeline of receiver bottom again, thereby avoid water to get into the quality that agitated reactor influences product.

The utility model helpfulness; The utility model is through being provided with seamless annulus and being arranged at groove below the annulus and having realized that the possible machine leak sealing water of agitated reactor discharges at shaft; Further increased the security of chemical reaction, sealing device is succinct, and is easy for installation; Need not to change the agitated reactor structure, realized the second protection of agitated reactor machine leak sealing water.

Fig. 2 is the utility model agitated reactor sealing device structure enlarged diagram.

Among the figure, the 1st, annulus, the 2nd, groove, the 3rd, drainpipe, the 4th, stirrer shaft, the 5th, reaction kettle cover, the 6th, bottom portion of groove.

The specific embodiment

Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.

In conjunction with Fig. 1 and Fig. 2.

The agitated reactor sealing device; Comprise reaction kettle body and agitator; Agitator is positioned on the reaction kettle cover 5, and in agitated reactor, stirrer shaft 4 tops have and the fixing annulus 1 of axle 4 seamless links; Annulus 1 outward flange below has annular groove 2, groove 2 to be fixed on the reaction kettle cover 5 and drainpipe 3 is arranged at bottom 6.Annulus 1 surface is edge tilt from inside to outside.Drainpipe 3 outlets are positioned at outside the agitated reactor.

As depicted in figs. 1 and 2; Agitated reactor comprises the reaction kettle body that is positioned at the bottom; On not useful bolt be connected fixing kettle cover 5 with reaction kettle body; This routine agitating device comprises stirring power resources motor, and motor drives shaft 4 realization responses through decelerator and stirs, and agitating device is installed on the reaction kettle cover 5.Shaft 4 needs sealing with reaction kettle cover 5 contact sites; Mechanical seal is adopted in usually existing shaft 4 sealings, and shaft 4 rotates wearing and tearing for a long time usually can make the mechanical seal seepage, and this example is at the fixing annulus 1 of shaft 4 top seamless links; Annulus 1 can be weldingly fixed on the shaft 4 through seamless; Also can pass through other modes such as bolt connection or welding, carry out the slit filling at the connection seam then and make the connection seam non-leakage, in order to make annulus 1 draining unobstructed; Can annulus 1 be set to the surface tilt structure, annulus 1 outward flange is lower than the middle part.One annular groove 2 is set below annulus 1 outward flange; Purpose is to receive the percolating water that annulus 1 outward flange is discharged; Annular groove 2 does not contact with shaft 4, and the rotation of shaft 4 and annulus 1 is contact ring connected in star 2 not, and annular groove 2 is connected fixing through bolt or other fixing means with reaction kettle cover 5; The width of annular groove 2 and the degree of depth are purpose with agitated reactor size decision, particularly width can receive annulus 1 discharge percolating water.Annular groove 2 bottoms 6 are provided with the outer drainpipe 3 of coupled reaction still, and the percolating water that annular groove 2 receives is discharged outside the agitated reactor through drainpipe 3.
