Abstract
The utility model discloses a stirring shaft connecting and sealing device which comprises two branch flanges, wherein the two branch flanges are respectively fixed at the end parts of a two-sectioned stirring shaft and can rotate along with the stirring shaft; and the two branch flanges are fixedly connected, the middle part of each branch flange is provided with a flange hole, a flange plate is arranged on the circumference edge of each branch flange, the flange plates of the two branch flanges are fixedly connected, an annular sealing groove is formed in one side, which is towards the flange plate of the other branch flange, of one flange plate, and a seal ring is arranged in each annular sealing groove so as to form sealing fit of the two branch flanges. According to the stirring shaft connecting and sealing device, the annular sealing groove is formed in the inner side of a connecting bolt of each branch flange, and the seal ring is additionally arranged in each annular sealing groove, so that a medium can be prevented from inward permeating and the microbiological contamination at the connecting part of the branch flanges is avoided.
Description
Technical field
The utility model relates to the agitator technical field, is specifically related to a kind of shaft sealing apparatus for connection.
Background technology
In stirring system, because of the maximization of equipment or the restriction of installing space, the segmentation shaft that causes the shaft of transferring power need be divided into multistage connects.Connecting mode is considered from health or cost, adopts the situation of flange form connection more.In the situation that pharmaceutical industry or other are had relatively high expectations to apparatus sanitation, the part that can't sterilize in the time of can not having dead angle or high-temperature sterilization in General Requirements equipment, and the position of flange connect, when connecting, it adopts the modes such as bolt, shaft is in medium for a long time, and the dichotomy method orchid also long-term existence is in medium thereupon, inevitably medium can infiltrate in minute flange internal cavities along the blue side that coordinates of dichotomy method, the inside of dividing in the course of time flange is just long-pending has expired material and has produced the microbiological contamination phenomenon.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides a kind of shaft sealing apparatus for connection of good sealing effect.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of shaft sealing apparatus for connection, comprise two minutes flanges that are separately fixed at two segmentation shaft ends and can rotate with shaft, flange was fixedly connected with in described two minutes, be provided with flange hole in the middle part of described minute flange, minute flange week, the ring flange of described two minutes flanges was fixedly connected with along being provided with ring flange, and one of them ring flange is towards the annular seal groove that is provided with of a side of ring flange of another minute flange, be provided with sealing ring in described annular seal groove, form being sealed and matched of dichotomy method orchid.
As preferably, the ring flange of described dichotomy method orchid is fixedly connected with by the mode of bolt.After the mode of employing bolt is fixedly connected with two minutes flanges, under the basis that guarantees fixed effect, can facilitate the installing/dismounting of segmentation shaft, more convenient practicality.
As preferably, the mode of the madial wall of described flange hole by welding is fixedly connected with segmentation shaft end.After adopting above-mentioned preferred version, can make minute shaft and minute flange fixing more firm.
As preferably, the mode of the madial wall of described flange hole by screw thread is fixedly connected with segmentation shaft end.After adopting above-mentioned preferred version, can make minute shaft and minute flange fixing more firm.
As preferably, described flange hole and described segmentation shaft end whole installation.After adopting above-mentioned preferred version, with segmentation shaft and a minute flange integrated setting, avoided minute flange to break away from from the segmentation shaft because of long-term the use.
As preferably, in described minute flange one of them minute flange ring flange be provided with limited step, another minute the ring flange of flange be provided with the spacing projection that embeds in limited step.After adopting above-mentioned preferred version, the cooperation of spacing projection and limited step can effectively prevent the relative slippage of minute flange, guarantees the concentricity requirement of minute off-axis.
Shaft sealing apparatus for connection of the present utility model arranges annular seal groove and set up a sealing ring in annular seal groove in the attachment bolt inboard of minute flange, can prevent that just medium from infiltrating toward inner, avoided a minute flange connection place microbiological contamination.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
as shown in Figure 1, embodiment of the present utility model is a kind of shaft sealing apparatus for connection specifically, comprise two minutes flanges that fixedly are located at respectively two segmentation shaft 1 ends and can rotate with the segmentation shaft, the dichotomy method orchid is respectively upper flange 2 and lower flange 3, upper flange 2 is fixedly connected with lower flange 3, upper flange 2 middle parts are provided with upper flange hole 21, week is along being provided with upper flange plate 22, lower flange 3 middle parts are provided with lower flange hole 31, week is along being provided with lower flange 32, upper flange plate 22 is provided with upper flange bolt hole 221, lower flange 32 is provided with and the corresponding lower flange bolt hole 321 of upper flange bolt hole 221, upper flange plate 22 is fixedly connected with by an attachment bolt 4 with lower flange 32, attachment bolt 4 passes respectively upper flange bolt hole 221 and lower flange bolt hole 321, upper flange plate 22 is fixedly connected with lower flange 32.Lower flange 32 is provided with towards a side of upper flange plate 22 annular seal groove 322 that arranges along the circumferential direction of lower flange 32, is provided with sealing ring 5 in annular seal groove 322, forms being sealed and matched of upper flange 2 and lower flange 3.Certainly, annular seal groove 322 also can be arranged on upper flange.
The madial wall in upper flange hole 2 is fixedly connected with segmentation shaft 1 end by the mode of welding.The madial wall in lower flange hole 3 is fixedly connected with segmentation shaft 1 end by the mode of welding.The upper flange plate 22 of upper flange 2 is provided with limited step 222, and the lower flange 32 of lower flange 3 is provided with the spacing projection 323 that embeds in this limited step 222.
The operation principle of the shaft coupling arrangement of the operation principle of shaft sealing apparatus for connection of the present utility model and prior art is basic identical, difference is: shaft sealing apparatus for connection of the present utility model arranges annular seal groove 322 and set up a sealing ring 5 in annular seal groove 322 in attachment bolt 4 inboards of minute flange, just can prevent that medium from infiltrating toward inner, avoided a minute flange connection place microbiological contamination.
