Embodiment Construction

[0012] Such as figure 1 As shown, the present invention includes an upper canopy 1 , a lower canopy 2 , a pipeline 3 and a material layer carrying device 4 . Among them, the upper canopy and the lower canopy are both frustum-shaped hollow thin-walled structures, and the characteristic size of the upper section is smaller than that of the lower section. The layer carrying device 4 is fixedly connected, the lower end of the upper canopy 1 is loosely fitted outside the lower canopy 2; the upper end of the lower canopy 2 is loosely fitted inside the upper canopy 1 and outside the pipe 3, and the material layer carrying device 4 is loosely fitted on the pipe 3 outside. In this way, the material layer carrying device 4 and the pipeline 3 can move relatively within a certain height range along the axial direction of the pipeline, that is, the upper canopy 1 and the lower canopy 2 can move relatively in the height direction, but the range of movement cannot be too large, so that the ...

Abstract

The invention relates to a canopy type material sealing device which comprises an upper canopy (1), a lower canopy (2), a pipeline (3) and a material layer bearing device (4), wherein the upper end of the upper canopy (1) is fixedly connected with the pipeline (3); the lower end of the upper canopy (1) is sheathed outside the lower canopy (2); the lower end of the lower canopy (2) is fixedly connected with the material layer bearing device (4); the upper end of the lower canopy (2) is sheathed on the pipeline (3) to ensure that the lower canopy (2) is capable of relatively moving along the axial direction of the pipeline (3); and the material layer bearing device (4) is sheathed on the pipeline (3) to ensure that the material layer bearing device (4) is capable of relatively moving along the axial direction of the pipeline (3). Through the upper and lower canopies which are sheathed in a loosening manner, the fixed connection between the pipeline and the material layer bearing device is avoided, so that the pipeline and the material layer bearing device are capable of relatively moving in a certain range and the materials do not leak.

Description

technical field [0001] The invention relates to a granular material processing device, in particular to an umbrella-type material sealing device when a pipeline passes through a granular material layer carrying device. Background technique [0002] In industrial production, it is often necessary to process a large amount of granular materials. These materials are arranged in the form of material layers on the carrying device. When a pipe passes through the carrying device, the specific process does not allow welding, bonding, etc. of the pipe and the carrying device. If it is connected, there will be leakage of granular materials in the gap between the pipe and the bearing device. When the pipeline passes through the material and its carrying device in the vertical direction, in order to prevent the material from leaking from the gap between the pipe and the carrying device, it is necessary to fix the pipe and the material carrying device (welding, bonding, etc.), but with t...
