Abstract

The invention discloses a sealing device for a high-pressure and high-speed reaction kettle, which comprises a moving ring, a moving ring sealing ring and a main axle; wherein the moving ring is fixedly sleeved at the outer side of the main axle, and the moving ring sealing ring is arranged between the radial gaps of the moving ring and the main axle; by taking the using direction as the reference, an annular stopping ring is arranged between the axial gaps of the moving ring and the end face of the moving ring sealing ring. According to the sealing device for the high-pressure and high-speed reaction kettle, the service life of the moving ring sealing ring is prolonged, the sealing effect is ensured, and the poor sealing of the moving ring sealing ring caused by deforming under the high temperature and high pressure can be avoided; the annular stopping ring can be directly replaced when it is damaged in use, and the moving ring sealing ring does not need to be replaced, and the producing efficiency is improved.

Description

The high-voltage high-speed reaction kettle is used seal arrangement
Technical field
The present invention relates to a kind of seal arrangement, particularly a kind of high-voltage high-speed reaction kettle is used seal arrangement.
Background technique
At present, high-voltage high-speed reaction kettle commonly used with seal arrangement in, only adopt the seal ring of moving ring sealing between its rotating ring and the main shaft, and in high temperature and high pressure environment, the damage of rotating ring easy deformation is changed cumbersomely, influences manufacturing efficiency.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of high-voltage high-speed reaction kettle and use seal arrangement, this device can improve the working life of seal ring of moving ring, guarantees excellent sealing performance.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of high-voltage high-speed reaction kettle is used seal arrangement, comprises rotating ring and seal ring of moving ring and main shaft, and the rotating ring fixed cover is located at the main shaft outside (during work; Rotating ring 1 rotates with main shaft 4), seal ring of moving ring (is preventing the gap leakage between medium driven torus and the main shaft 4, is sealing) between the radial clearance of rotating ring and main shaft; To use direction to be benchmark, be provided with an annular retaining ring between the axial clearance of said rotating ring and seal ring of moving ring end face, annular retaining ring is set plays the effect of effective protection seal ring of moving ring; Increase seal ring of moving ring working life; Guarantee sealing effect, avoid seal ring of moving ring because HTHP is out of shape the poor sealing that the back produces, in the using process; In case annular retaining ring damages; Can directly change, and need not change seal ring of moving ring, easy to operate.
As further improvement of the present invention, the radial clearance of said annular retaining ring and main shaft is between the 0.05-0.1 millimeter.
As further improvement of the present invention, be benchmark to use direction, said annular retaining ring is provided with the annular groove of indent near the end face of seal ring of moving ring one side; In this example, annular retaining ring is provided with the annular groove of indent near the end face of seal ring of moving ring one side, (can also not establish the annular groove of indent; Annular retaining ring is a horizontal plane near the end face of seal ring of moving ring one side); The groove structure that is provided with indent can reduce area of contact, thereby reduces friction longer service life.
As further improvement of the present invention; Said annular retaining ring is that the elastic material of high temperature high voltage resistant is processed, the high-voltage high-speed reaction kettle with seal arrangement in, annular retaining ring need bear higher ambient temperature and pressure; Adopt the elastic material of high temperature high voltage resistant to make, can improve its usability.
The invention has the beneficial effects as follows: this high-voltage high-speed reaction kettle is provided with an annular retaining ring with seal arrangement between the axial clearance of said rotating ring and seal ring of moving ring end face, can increase the working life of seal ring of moving ring, guarantees sealing effect; Avoid seal ring of moving ring because the poor sealing that HTHP distortion back produces; In the using process,, can directly change in case annular retaining ring damages; And need not change seal ring of moving ring, enhance productivity.

Fig. 2 is a structural representation of the present invention;
Fig. 3 is the annular retaining ring structural representation of concave ring groove in being provided with.
Embodiment
Embodiment: a kind of high-voltage high-speed reaction kettle is used seal arrangement, comprises rotating ring 1 and seal ring of moving ring 2 and main shaft 4, and rotating ring 1 fixed cover is located at main shaft 4 outsides (during work; Rotating ring 1 rotates with main shaft 4), seal ring of moving ring 2 (is preventing the gap leakage between medium driven torus and the main shaft 4, is sealing) between the radial clearance of rotating ring 1 and main shaft 4; To use direction to be benchmark, be provided with an annular retaining ring 3 between the axial clearance of said rotating ring 1 and seal ring of moving ring 2 end faces, annular retaining ring 3 is set plays effective protection seal ring of moving ring 2 effects; Increase by 2 working lifes of seal ring of moving ring, guarantee sealing effect, avoid seal ring of moving ring 2 because the poor sealing that HTHP distortion back produces; In the using process,, can directly change in case annular retaining ring 3 damages; And need not change seal ring of moving ring 2, easy to operate.
The radial clearance of said annular retaining ring 3 and main shaft 4 is between the 0.05-0.1 millimeter.
Using direction to be benchmark, said annular retaining ring is provided with the annular groove 5 of indent near the end face of seal ring of moving ring 2 one sides, in this example; Annular retaining ring is provided with the annular groove 5 of indent near the end face of seal ring of moving ring 2 one sides; (can also not establish the annular groove 5 of indent, annular retaining ring 3 is a horizontal plane near the end face of seal ring of moving ring 2 one sides), annular groove 5 structures that are provided with indent can reduce area of contact; Thereby reduce friction longer service life.
Said annular retaining ring 3 is processed for the elastic material of high temperature high voltage resistant, the high-voltage high-speed reaction kettle with seal arrangement in, annular retaining ring 3 need bear higher ambient temperature and pressure, adopts the elastic material of high temperature high voltage resistant to make, and can improve its usability.
