Problems solved by technology
[0002] In order to prevent the goods from being polluted or the goods from polluting the environment, the existing cement, coal, grain and other dry bulk cargoes are transported using closed conveying devices such as pipelines. The existing dry bulk cargo conveying pipe movable joint sealing device has Can achieve sealing when inactive, but poor sealing performance when active
And because the structure of the active joint sealing device of the existing dry bulk cargo conveying pipe is complicated, its installation and maintenance are complicated, and its manufacturing cost is high

The invention relates to a sealing device for a flexible joint of a dried bulkload delivery pipe, which ensures good tightness as well as good mobility, and has simple structure and low manufacturing cost. The sealing device comprises a feeding device, a discharging device, a flexible joint sealing structure and a connection structure, wherein one end of the connection structure is tightly and fixedly connected with the discharging device, and the flexible joint sealing structure is wrapped by the connection structure. The sealing device is characterized in that the flexible joint sealing structure comprises an O-shaped ring, an annular rubber pad, a disk spring piece, an axial clearance flange, a sealing flange and a pressure plate flange; the flange plate of the feeding device is tightly and fixedly connected with the sealing flange, the axial clearance flange, the annular rubber pad, the disk spring piece and the pressure plate flange along the axial direction in sequence, and the centre lines thereof are overlapped; the O-shaped ring is arranged in the cavity formed by the annular rubber pad and the inner wall of the other end of the connection structure; and a confined space is formed by the O-shaped ring, the annular rubber pad and the inner wall of the other end of the connection structure.
Description
(1) Technical field [0001] The invention relates to the field of dry bulk cargo logistics equipment, in particular to a sealing device for movable joints of dry bulk cargo conveying pipes. (2) Background technology [0002] In order to prevent the goods from being polluted or the goods from polluting the environment, the existing cement, coal, grain and other dry bulk cargoes are transported using closed conveying devices such as pipelines. The existing dry bulk cargo conveying pipe movable joint sealing device has In the case of inactivity, the seal can be achieved, but in the case of movement, the sealing performance is poor. Moreover, due to the complicated structure of the sealing device for the movable joint of the existing dry bulk cargo conveying pipe, its installation and maintenance are complicated, and its manufacturing cost is high. (3) Contents of the invention [0003] In view of the above problems, the present invention provides a sealing device for movable ...
