In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of for the seal arrangement between rotatingshaft and container body, and its installation is comparatively simple and convenient.
For solving the problem, the technological scheme that the utility model adopts is as follows:
For the seal arrangement between rotatingshaft and container body, comprise socket on the rotating shaft and can along with rotatingshaft rotate sleeve pipe, be arranged on the seal ring between rotatingshaft and sleeve pipe, the fixed base be connected on container body; Described fixed seating outside sleeve pipe, and has gap between the inwall of fixed base and the outer wall of sleeve pipe; Sealing device also comprises and is arranged on upper Sealing between sleeve pipe and fixed base, is arranged on lower seal between sleeve pipe and fixed base.
Described sleeve pipe, fixed base, between upper Sealing and lower seal, surround a chamber.
Described sleeve pipe is fixed by screws on rotatingshaft.
Described upper Sealing, lower seal are all fixed on the inwall of fixed base.
Described upper Sealing, lower seal are arranged up and down along the axis of sleeve pipe.
Described rotatingshaft, sleeve pipe, fixed base are arranged in coaxial.
Described upper Sealing corresponds to the upper end of fixed base, and lower seal corresponds to the lower end of fixed base.
External diameter in the middle part of described sleeve pipe is greater than the external diameter at other positions of sleeve pipe.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model, by adopting the combination design of sleeve pipe, fixed base, upper Sealing, lower seal, effectively can realize vacuum pressure sealing, and it is comparatively simple and convenient that it can be made to install, and meanwhile, its longer service life also can be made of a specified duration; And making, the processing of each part are comparatively simple, are conducive to reducing fabricating cost; In addition, in the course of the work, its pressure produced is only stream pressure, and when rotatingshaft rotates, ability mineralization pressure room, does not need extra supplement heat rejecter medium, can not to environment.

Wherein, 1, rotatingshaft; 2, sleeve pipe; 3, seal ring; 5, fixed base; 6, upper Sealing; 7, chamber; 9, screw; 10, lower seal.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further, understands the utility model technical thought required for protection so that clearer.
Fig. 1,2 illustrates the structural representation of the first mode of execution for the seal arrangement between rotatingshaft and container body, and sealing device comprises the sleeve pipe 2, seal ring 3, the fixed base 5 be connected on container body that are socketed in and rotatingshaft 1 also can rotate along with rotatingshaft 1; Described seal ring 3 is arranged between rotatingshaft 1 and sleeve pipe 2, with to standstill seal between rotatingshaft 1 and sleeve pipe 2; Described fixed base 5 is enclosed within outside sleeve pipe 2, and has gap between the outer wall of the inwall of fixed base 5 and sleeve pipe 2; Sealing device also comprises and is arranged on upper Sealing 6 between sleeve pipe 2 and fixed base 5, is arranged on lower seal 10 between sleeve pipe 2 and fixed base 5.Described sleeve pipe 2, fixed base 5, between upper Sealing 6 and lower seal 10, surround a chamber 7.Concrete, described rotatingshaft 1, sleeve pipe 2, fixed base 5 are arranged in coaxial.Described upper Sealing 6, lower seal 10 are arranged up and down along the axis of sleeve pipe 2.The outer wall of described fixed base 5 is connected with container body.
Preferably, described sleeve pipe 2 is fixed on rotatingshaft 1 by screw 9, to improve the stability that sleeve pipe 2 is installed, prevents sleeve pipe 2 from occurring the phenomenon that slides axially.
Described upper Sealing 6, lower seal 10 are all in rotational-like.On this, Sealing 6, lower seal 10 are all fixed on the inwall of fixed base 5.Concrete, the end corresponding to sleeve pipe 2 outer wall of described upper Sealing 6, lower seal 10 is opening end.And by adopting said structure, can guarantee that its sealability simultaneously, is also convenient to dismounting.
Described upper Sealing 6 corresponds to the upper end of fixed base 5, and lower seal 10 corresponds to the lower end of fixed base 5.And by adopting said structure, effectively can expand the volume of chamber 7, more can make full use of space.
External diameter in the middle part of described sleeve pipe 2 is greater than the external diameter at other positions of sleeve pipe 2.
Concrete, described sleeve pipe 2 is provided with the locating slot embedded for seal ring 3, to make the installation of seal ring 3 more convenient, simple, is also convenient to the location of seal ring 3.Certainly, described locating slot also can be arranged on rotatingshaft 1, can be convenient to the location of seal ring 3 equally.
Wherein, the quantity of seal ring 3 can be set to according to actual demand one, two or more.
In rotatingshaft 1 working procedure, rotatingshaft 1 rotates, and drives sleeve pipe 2 and seal ring 3 synchronous axial system, and now, rotatingshaft 1, sleeve pipe 2 are in relative static conditions with seal ring 3 three parts; And fixed base 5, upper Sealing 6, lower seal 10, with container body be in relative static conditions; The air-flow produced when rotatingshaft 1 rotates can form certain pressure by the interstitial area between sleeve pipe 2 and fixed base 5, and by the cooperation of upper Sealing 6 and lower seal 10 can mineralization pressure room (namely, described chamber 7 is formed as pressure chamber), pressure chamber keeps apart ambient atmosphere and container body sealed sides, can prevent ambient atmosphere from entering in container body, also gas leakage in container body can be prevented in ambient atmosphere, thus reach sealing effect.
The utility model is by adopting the combination design of sleeve pipe 2, fixed base 5, upper Sealing 6, lower seal 10, and by rationally arranging the annexation of each part, effectively can realize vacuum pressure sealing, and it is comparatively simple and convenient that it can be made to install, meanwhile, its longer service life also can be made of a specified duration; And making, the processing of each part are comparatively simple, are conducive to reducing fabricating cost; In addition, in the course of the work, its pressure produced is only stream pressure, and when rotatingshaft 1 rotates, ability mineralization pressure room, does not need extra supplement heat rejecter medium, can not to environment.
Fig. 3 is the structural representation of the second mode of execution of the present utility model, and the difference of itself and Fig. 1 is only: the structure of upper Sealing 6, lower seal 10.In figure 3, described upper Sealing 6, lower seal 10 include two external members.Wherein, the quantity of the external member that described upper Sealing 6, lower seal 10 comprise is not limited in one, two, can also be set to two or more.Certainly, except the structure shown by Fig. 1, Fig. 3, upper Sealing 6, lower seal 10 can also be set to other shapes.
Above-mentioned mode of execution is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
