Description
Technical field
The present invention relates to a kind of chemical reaction kettle, especially a kind of chemical autoclave sealing fastening structure.
Background technology
In most of chemical reaction; Because the characteristic of reactant itself; It is long to make that many chemical reactions all exist the reaction time in the process of carrying out suitability for industrialized production, the defective that reaction efficiency is low, even some reactant or product all are to human poisonous and harmful substance.Simultaneously; Also because the external condition of many chemical reactions desired harshness when reacting; Like various conditions such as high temperature, high pressure, insulation, heat radiations, make many reactions exist not only that production efficiency is low, the cycle long, waste is serious, the unfavorable result of contaminated environment.Therefore the appearance of autoclave just seems particularly important; It will make the effective rate of utilization and the safety coefficient of industry improve greatly; Not only can bring good economic benefit, more can give society and a human harmony, the comfortable live and work environment of providing enterprise.And can autoclave operate as normal depend on the degree of perfection of hermetically-sealed construction to a great extent, as long as partly reasonably design, make, install at the fastening structure at its sealing position, accident is avoidable fully.
Active force according to sealing is different, and the hermetically-sealed construction form that agitated reactor is commonly used can be divided three classes: 1) forced seal: rely on and tighten kingbolt and make and have certain contact stress between top cover, potted component and the cylindrical shell end and reach sealing.In press rise after, bolt elongate, the top cover come-up, contact stress reduces.Require big bolt pretightening to guarantee in working order that down the sealing property between pad and top cover, the cylindrical shell end is reliable.2) semi-automatic seal: utilize bolt pretightening to make potted component produce strain and the preload pressure of setting up initial sealing is provided, after pressure raise, the contact stress of sealing surface also rose thereupon, has guaranteed sealing property.3) self-tightening sealing: rely on design feature separately; Contact stress between pad and the cylindrical shell end raises with operating pressure and increases; High pressure lower seal performance is better; During pretension, much little for setting up bolt force that initial sealing the applies bolt force required than forced seal, generally without large diameter bolt.
Usually; When the hermetically-sealed construction position of design autoclave; Main consider satisfy that the convenient processing and manufacture of fastening position, potted component are few, on simple light and handy, hermetically-sealed construction is compact, potted component is corrosion-resistant etc. the basis of securing member; Also need be convenient to maintenance is installed, alleviate the labour intensity of assembling and dissembling process, the consideration of security performance also is an extremely important factor certainly.
Therefore; In the production process of enterprise; General fastening structure (the Fig. 1 that adopts many bolts in sealing position; 2), the fastening structure at agitated reactor sealing position mainly comprises: pallet 1, kettle cover 2, O shape circle 3, kettle 4, fastening bolt 5, pad 6, clamp nut 7, temperature test socket 8, pressure test socket 9, stirring rod socket 10.Wherein in Fig. 1, pallet 1, kettle cover 2 and kettle 4 are according to the chemical reaction requirement, and fastening bolt 5, pad 6 and clamp nut 7 are standard component, and size is M10,8.8 grades of strength grades.Because a lot of agitated reactors need frequent reloading, need often dismounting fastening bolt 5, pad 6 and clamp nut 7, make operating process quite loaded down with trivial details and inconvenient.The labour intensity of disassembly process is bigger, and the loading and unloading amount is more, also causes the damage at sealing position simultaneously easily, is difficult to adapt to the needs of producing and living.
Summary of the invention
The present invention will solve the many bolt fastening structure mounting or dismounting in existing agitated reactor sealing position inconvenience; Cause the technical problems such as damage at sealing position easily, and provide a kind of agitated reactor sealing position fastening structure, this structure not only can solve traditional agitated reactor dismounting inconvenience; Problems such as labour intensity is excessive; Also can avoid in disassembly process damage to the sealing position, cheap, economical and practical.
For achieving the above object, the present invention adopts following technical proposals:
A kind of agitated reactor sealing position fastening structure comprises pallet, kettle cover, is characterized in: pallet and kettle cover are provided with O-ring seals through being threaded on the pallet and between the kettle cover flange lower surface.
Have grip hole on the flange face of cylinder of kettle cover, adorn, when tearing open, insert the handle of screwing in the grip hole; Have the groove of placing O-ring seals 3 on the pallet upper surface.
The present invention has following beneficial effect compared with prior art:
1) adopts being threaded of kettle cover and kettle to substitute the fastening structure of a plurality of bolt and nuts, have simple in structure, easy to operate advantage;
2) adopt the structure of screwing handle and grip hole,, make that the O shape circle at sealing position is stressed evenly, not fragile, prolonged the service life at sealing position compared to the fastening structure of a plurality of different parts.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a single screw thread rotation formula fastening structure cutaway view of the present invention;
Fig. 4 is the vertical view of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Shown in 3,4, agitated reactor sealing of the present invention position fastening structure comprises pallet 1, kettle cover 2, O-ring seals 3, kettle 4, the handle 11 of screwing, temperature test socket 8, pressure test socket 9, stirring rod socket 10, grip hole 12 etc.
Pallet 1 and kettle cover 2 are provided with O-ring seals 3 through being threaded between pallet 1 upper end and the kettle cover 2 flange lower surfaces.
Have grip hole 9 on the flange face of cylinder of kettle cover 2, during mounting or dismounting, insert the handle 11 of screwing in the grip hole 12.Have the groove of placing O-ring seals 3 on pallet 1 upper surface.
Pallet 1, kettle cover 2 and kettle 4 adopt the material of 1Cr18Ni9Ti according to the chemical reaction requirement, and O shape circle 3 is sulfuration nitrile rubber material, and dismounting handle 11 is No. 45 steel, and O shape circle is sulfuration nitrile rubber material.The screw thread processing of grip hole 12, kettle cover 2 and kettle 4 designs and produces according to producing pressure.
Operation principle before and after improving is following: for the structure before improving, like Fig. 1, shown in 2; The material that is used to react is positioned over kettle 4 inside, and pallet 1 welds together with kettle 4, and the temperature test socket 8 on kettle cover 2, pressure test socket 9, stirring rod socket 10 positions install after temperature test sensor, Pressure gauge and the stirring rod; O shape circle 3 is installed in the groove of pallet 1, at last pallet 1 and kettle cover 2 is adopted securing member, comprise fastening bolt 5, pad 6, clamp nut 7; Be assembled together, after kettle 4 inner material reactions are accomplished, unclamp clamp nut 7; Pull down fastening bolt 5, pad 6, take kettle cover 2 off, after kettle is cleaned; Be reentered into material, carry out the installation of above-mentioned steps again.
Because material needs frequent replacing, need often dismounting fastening bolt 5, pad 6 and clamp nut 7, make operating process quite loaded down with trivial details and inconvenient.
The present invention is through technological improvement, with Fig. 1, needs the fastening part of often dismounting carry out design again in 2; Like Fig. 3; Shown in 4, adopt being threaded between kettle cover 2 and the kettle 4 to substitute, unloading process mainly adopts the structure of screw handle 11 and grip hole 12 among Fig. 4 to accomplish; Pallet 1 improves processing accordingly, and other parts are constant.
