Description

Technical Field

[0001] This utility model relates to the field of dynamic sealing technology, specifically to a dynamic sealing device for continuous oxygen-free pyrolysis equipment. Background Technology

[0002] Conventional rotary equipment uses packing with fish-scale seals or packing with gas seals. After operating in a high-temperature environment for a period of time, a certain gap will be generated between the packing seal and the cylinder, making it impossible to maintain an oxygen-free state. Conventional gas seals use an external steam drum ring, which poses a risk of leakage during long-term operation and in high-temperature environments, thus presenting a problem.

Detailed Implementation

[0011] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0012] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0013] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. To make the foregoing objects, features, and advantages of this invention more apparent and understandable, the specific implementation of this invention is described in detail below with reference to specific embodiments: such as Figure 1 The present invention is achieved through the following technical solution: a dynamic sealing device for continuous oxygen-free pyrolysis equipment, comprising a discharge cylinder 1, characterized in that: a pressure equalization chamber 4 is fixedly connected to the discharge cylinder 1, an air inlet pipe 3 is fixedly connected to the pressure equalization chamber 4, a bracket 5 is fixedly connected to the pressure equalization chamber 4, a rotary cylinder 13 is rotatably connected to the discharge cylinder 1, a rotary retaining ring 2 is fixedly connected to the discharge cylinder 1, a rotary retaining ring 2 is fixedly connected to the rotary cylinder 13, the two rotary retaining rings 2 are rotatably connected, and the rotary retaining ring 2 on the discharge cylinder 1 is located at the opening of the pressure equalization chamber 4; A packing 6 is rotatably connected to the rotary cylinder 13, and a retaining ring 14 is fixedly connected to the rotary cylinder 13. The packing 6 is clamped between the retaining ring 14 and the retainer 7. The bracket 5 is fixedly connected to the retainer 7 through a first clamping device 8. A stop block 11 is fixedly connected to the retainer 7 by bolts. The stop block 11 is fixedly clamped to the graphite body 10 on the retainer 7 by a second clamping device 12.

A bolt is threadedly connected to the retainer 7, and the bolt is tightened against the pressure equalizing ring 9.

[0015] The working principle of this utility model is as follows: When the rotary cylinder 13 is running in a high-temperature environment, inert gas is injected into the equalizing chamber 4 through the air inlet pipe 3. The inert gas here can prevent the pyrolysis gas and dust from being emitted through the rotary baffle ring 2. The two rotary baffle rings 2 can reduce the leakage of pyrolysis gas and dust inside the discharge cylinder 1, and at the same time reduce the amount of gas used for inert gas sealing. This is the first layer of dynamic sealing structure. Packing 6 is set and pressed by the first pressing device 8 to further prevent leakage. Finally, the graphite body 10 provides dynamic sealing. The three-layer dynamic sealing structure prevents gaps from appearing between the cylinders.
