Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] figure 1 The general structure of the mechanical seal device 100 of the present invention is schematically shown. The mechanical seal device 100 includes a housing 107 , a stationary ring 106 accommodated in the housing 107 , and a moving ring 104 coaxially in contact with the static ring 106 and extending out of the housing 107 .

[0026] Such as figure 2 As shown, a flange connection hole 120 is formed on the housing 107 . Match the flange connection hole 120 on the housing 107 with the corresponding connection hole at the opening of the container 202, and insert the screw into the flange connection hole 120 and the connection hole on the container 202 to effectively connect the container 202 to the container 202. housing 107 as Figure 4 connected together as shown.

[0027] Preferably, as image 3 As shown, there are a plurality of, for example four, flang...

Abstract

The invention relates to a mechanical sealing device. The mechanical sealing device comprises a shell, a fixed ring contained in the shell, and a movable ring making contact with the fixed ring and extending out of the shell. The outer circumferential wall of the movable ring is smooth. When the shell is fixed to the position of an opening of a container, the movable ring will be arranged in the container, and a rotating shaft penetrates the fixed ring and the movable ring and is fixed to the movable ring. When the rotating shaft rotates, the movable ring rotates along with the rotating shaft, and the fixed ring is fixed in the circumferential direction. Through usage of the mechanical sealing device, impurity residues are not likely to be formed on the surface of the mechanical sealing device, and the mechanical sealing device is easy to clean.

Description

technical field [0001] The invention belongs to the field of mechanical seals, and in particular relates to a mechanical seal device. Background technique [0002] In the field of mechanics, structures are often encountered that require the insertion of a rotating shaft into a container. For example, for a reaction kettle, it is necessary to insert a stirrer in the kettle body, and the rotating shaft of the stirrer should extend out of the kettle body to facilitate the user to manipulate it. The mechanical seal device is a structure used to connect between the rotating shaft and the container to ensure the smooth rotation of the rotating shaft while keeping the container in a sealed state. [0003] In the prior art, the mechanical sealing device has a complex transmission structure, and the structural surface protruding into the container is uneven. In this way, the impurities in the container are easily bonded and adsorbed to this uneven surface, forming residues. Such r...
