Furthermore the mechanically sealed polytetrafluoroethylene mixer sleeve has the following advantages: low cost, stable performance, high convenience in use, easy popularization, good sealing effect, high practicability and high promotional value.
Description
Technical field
The utility model relates to the improvement of chemical experiment usefulness agitator sleeve structure in the chemical field, a kind of specifically Mechanical Sealed Type polytetrafluoroethylene (PTFE) agitator sleeve pipe.
Background technology
Agitator sleeve pipe described in the utility model, be meant in the chemical experiment of chemical field, the teflon sleeve that seals on the glass flask reactor that small lot batch manufacture is used, teflon sleeve is contained on the bottleneck of glass flask reactor, and the puddler of agitator passes teflon sleeve and enters in the glass flask reactor and stir.
Present polytetrafluoroethylene (PTFE) agitator sleeve pipe mostly is " a rubber seal formula ", and its structure is provided with rubber seal 01 as shown in Figure 1 between casing main body 1 that flexibly connects and sleeve pipe gland 2.During use, rubber seal is enclosed within on the agitator puddler 02, plays sealing function thereby tighten the sleeve pipe gland.The agitator sleeve pipe of this structure can keep sealing substantially under the normal pressure situation, but just can not keep condition of high vacuum degree, sealing for a long time under the agitator working order, and especially sealing effectiveness is poorer when temperature is high.Though can take to increase the number of plies of rubber seal, tighten methods such as sleeve pipe gland as far as possible, reach the sealing under the condition of high vacuum degree situation, but also increased the frictional resistance between rubber seal and the agitator puddler simultaneously, even the agitator puddler can't be rotated, can only do the vacuum distillation under the inactive state.Owing to there is not the stirring of agitator, the glass flask reactor internal reaction system inequality of being heated produces problems such as partial material coking, product quality decline, yield minimizing, working time prolongation.
The utility model content
The purpose of this utility model is at above-mentioned deficiency, and a kind of simple in structure, cheap, stable performance is provided, easy to use, be easy to popularize, the Mechanical Sealed Type polytetrafluoroethylene (PTFE) agitator sleeve pipe of good sealing effect.
The technical scheme that realizes the utility model purpose is:
This Mechanical Sealed Type polytetrafluoroethylene (PTFE) agitator sleeve pipe, casing main body and sleeve pipe gland by mutual flexible connection are formed, characteristics are to be provided with static seal circle and the dynamic seal ring that is in contact with one another connection in casing main body, and the bottom of static seal circle is provided with the quiet auxiliary seal ring that is connected with the casing main body contact; Be provided with on dynamic seal ring and the friction tight moving auxiliary seal ring of agitator puddler, the top of moving auxiliary seal ring is provided with the sealing reinforcing ring; Be provided with Flexible Connector on moving auxiliary seal ring, the top of Flexible Connector is provided with rolling bearing, and rolling bearing is connected with the contact of sleeve pipe gland; The internal diameter of casing main body, sleeve pipe gland, rolling bearing, dynamic seal ring, static seal circle and quiet auxiliary seal ring is greater than the external diameter of agitator puddler.
Described Flexible Connector can be that spring, silicon rubber loop or fluorine rubber ring etc. have certain flexible connector.When using spring to make Flexible Connector,, be added with packing ring above the spring between spring and rolling bearing in order to keep working stability.
In order to prevent that gas from expanding, and has steam vent on the contact-making surface of sleeve pipe gland and rolling bearing.
This Mechanical Sealed Type polytetrafluoroethylene (PTFE) agitator sleeve pipe, simple and reasonable, can select raw material and spare parts in common use such as existing polytetrafluoroethylene (PTFE), graphite, pottery, stainless steel for use, and adopt conventional processes to make, implement easily.Have that cost is low, stable performance, easy to use, be easy to popularize, advantage such as good sealing effect, have practical and popularizing value.
Description of drawings
Fig. 1 is the structural representation of existing rubber seal formula polytetrafluoroethylene (PTFE) agitator sleeve pipe.
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
Among the figure: 01 rubber seal, 02 agitator puddler; 1 casing main body, 2 sleeve pipe glands, 3 quiet auxiliary seal rings, 4 static seal circles, 5 dynamic seal rings, 6 moving auxiliary seal rings, 7 sealing reinforcing rings, 8 springs, 9 rolling bearings, 10 packing rings, 11 steam vents.
The specific embodiment
The utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this Mechanical Sealed Type polytetrafluoroethylene (PTFE) agitator sleeve pipe is made up of the casing main body 1 and the sleeve pipe gland 2 of mutual flexible connection, and the profile of casing main body and glass flask reactor bottleneck are complementary.Be provided with the static seal circle 4 and the dynamic seal ring 5 that are in contact with one another connection in casing main body, be provided with quiet auxiliary seal ring 3 in the bottom of static seal circle, quiet auxiliary seal ring is connected with the casing main body contact.Dynamic seal ring is provided with and the friction tight moving auxiliary seal ring 6 of agitator puddler, and the top of moving auxiliary seal ring is provided with sealing reinforcing ring 7.Be provided with spring 8 on the base frame of moving auxiliary seal ring, the top of spring is provided with rolling bearing 9, and rolling bearing is connected with the contact of sleeve pipe gland, has steam vent 11 radially on the contact-making surface of sleeve pipe gland and rolling bearing.The internal diameter of casing main body, sleeve pipe gland, rolling bearing, dynamic seal ring, static seal circle and quiet auxiliary seal ring is greater than the external diameter of agitator puddler.Be added with packing ring 10 above the spring between spring and rolling bearing.
The utility model applicant presses embodiment, implements this Mechanical Sealed Type polytetrafluoroethylene (PTFE) agitator sleeve pipe.Casing main body, sleeve pipe gland are made with polytetrafluoroethylene (PTFE).The optional usefulness of mechanical seal part is commercially available can bearing certain pressure the mechanical seal standard part, also can design and produce voluntarily, static seal circle, dynamic seal ring can select for use materials such as graphite, carborundum, tungsten carbide, oxide ceramic, aluminium oxide, stainless steel, carbon steel, copper to make.Quiet, moving auxiliary seal ring can select for use materials such as fluorubber, nitrile rubber, EP rubbers to make.
The on probation demonstration because the utility model has adopted the principle of mechanical seal, improved the sealing effectiveness of agitator sleeve pipe to greatest extent, and reduced frictional resistance through inside, just can drive agitator like a cork with the small machine of 50-60W and rotate.And under the condition of long-time higher temperature, also can keep the condition of high vacuum degree of glass flask reactor.Not only can make the glass flask reactor carry out the vacuum distillation of higher temperature expeditiously, also can be competent at chemical reaction and small lot batch manufacture work under the high vacuum condition fully, comprise the various experimental works under the conditions such as acidity, alkalescence.Thoroughly solve rubber seal formula polytetrafluoroethylene (PTFE) agitator bobbin seal weak effect, can not carry out the problem of the chemical experiment under the high vacuum state satisfactorily, not only can carry out the chemical reaction under the condition of normal pressure, and under higher temperature, condition of high vacuum degree condition, can keep mixing effect good for a long time, stable performance, easy to use is subjected to person on probation's general favorable comment.
