Abstract
A sealing device for a rotary shaft of a twin-screw feed desulfurization unit for scrap tire powder is provided with a sealing outer sleeve (1), a sealing inner sleeve (2), an O-shaped seal ring (3), and a combined seal (4), wherein the O-shaped seal ring (3) is disposed between the sealing inner sleeve (1) and the sealing outer sleeve (2), and the sealing outer sleeve (1) is provided with a circular water way (6) inside. The sealing device is characterized in that a positioning pin (5) fixed on the sealing inner sleeve is connected with the sealing outer sleeve (1), and cooling water is introduced into the water way (6). The sealing device is used to seal (achieving fine airtightness of the rotary shaft at high temperature) the rotary shaft at high temperature, and the service life of the seal is prolonged.
Description
Technical field
The present invention relates to a kind of junked tire powder desulphurization plant rotation shaft seal, be directly involved in the continuous double helix of junked tire powder normal pressure and advance desulphurization plant rotation shaft seal.
Background technique
At present, reclaiming processing industry normal pressure continuous helical at junked tire advances the sealing of desulphurization plant running shaft generally to adopt soft packing seal mode (being commonly called as packing_seal).The normal pressure continuous helical advances desulphurization plant to replace traditional dynamic devulcanizer to be widely adopted, and this equipment is compared with traditional dynamic devulcanizer, has without advantages such as waste water, toxic emission, energy saving.It is not thorough that yet the sealing of running shaft adopts the soft packing seal mode to seal, and for the wearing and tearing that compensate filler also need constantly to compress gland screw, working service is loaded down with trivial details, and because of Environmental Conditions temperature height, the working life of filler is low simultaneously.
Summary of the invention
Purpose of the present invention will provide a kind of improved junked tire powder double helix to advance desulphurization plant rotation shaft seal exactly, and it is not thorough that it can solve soft packing seal, gas leakage problem, the working life of having improved simultaneously Sealing.
The object of the present invention is achieved like this: a kind of junked tire powder double helix advances desulphurization plant rotation shaft seal, have hermetically sealed case, sealing inner sleeve, Sealing, feature is to adopt the sealing of twice heatproof O RunddichtringO between sealing inner sleeve, the hermetically sealed case, the twice combination seal is adopted in sealing between sealing inner sleeve and the running shaft, stuffing box gland water flowing cooling.
Description of drawings
Accompanying drawing 1 is the main sectional view of sealing device for rotary shaft among the present invention.Below in conjunction with accompanying drawing 1, the invention will be further described.
Embodiment
Accompanying drawing 1 shows the structure principle chart that a kind of junked tire powder of the present invention double helix advances main apparent place in the desulphurization plant sealing device for rotary shaft.By 3 sealings of the high temperature resistant O RunddichtringO of twice, 4 sealings of twice combination seal are adopted in the sealing between running shaft 7 and the sealing inner sleeve 2 between hermetically sealed case 1 and the sealing inner sleeve 2, and sealing inner sleeve 2 is connected connection by locating stud 5 with hermetically sealed case, prevent from relatively rotating; Gap between hermetically sealed case 1 and the sealing inner sleeve 2 is 0.5mm, and sealing inner sleeve 2 can be floated with running shaft 7 appropriateness in hermetically sealed case 1 endoporus; The hermetically sealed case 1 interior water channel 6 water flowings cooling sealing device that arranges; Whole seal arrangement on body, is realized the sealing under running shaft 7 hot environments by the bolton on the hermetically sealed case 1.
Claims (1)
1. a junked tire powder double helix advances desulphurization plant rotation shaft seal, have hermetically sealed case (1), sealing inner sleeve (2), mounting O-shaped seal ring (3) between hermetically sealed case (1) and the sealing inner sleeve (2), between sealing inner sleeve (2) and the running shaft (7) combination seal (4) is installed, establish water annulus (6) in the hermetically sealed case (1), it is characterized in that: the locating stud (5) that is fixed on the sealing inner sleeve (2) is connected 1 with hermetically sealed case) connect, water channel (6) leads to cooling water.
