Sleeve sealing device

Abstract

The invention relates to a sleeve-type material sealing device. The sleeve-type material sealing device comprises M upper sleeves (1), N lower sleeves (2), a pipeline (3) and a material layer bearing device (4), wherein M is greater than or equal to 1, and N is greater than or equal to 1. The upper ends of the upper sleeves (1) are fixedly connected with the pipeline (3); the lower ends of the upper sleeves (1) are open pipe ends; the upper ends of the lower sleeves (2) are open pipe ends; the lower ends of the lower sleeves (2) are fixedly connected with the material layer bearing device (4); and the material layer bearing device (4) is sleeved on the pipeline (3). According to the invention, through a mutually and loosely sleeved cylindrical structure, the pipeline is prevented from being fixedly connected with the material layer bearing device, the pipeline and the material layer bearing device can perform relative movement in a certain range, and materials cannot be leaked.

Description

technical field [0001] The invention relates to a granular material processing device, in particular to a sleeve-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 the pipeline passes through the material and its carrying device in the vertical direction, in order to prevent the material If there is any gap leakage, the pipeline and the material carrying device need to be fixed (welded, bonded, etc.), but at the same time, due to structural needs, the pipeline often needs to be connected with the outer structure (such as the equipment casing, steel frame, etc.), that is, there are two fixed points on a straight pipe, then when the pipe is heated, the thermal stress between the two fixed points cannot be eliminat...

Problems solved by technology

[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 the pipeline passes through the material and its carrying device in the vertical direction, in order to prevent the material If there is any gap leakage, the pipeline and the material carrying device need to be fixed (welded, bonded, etc.), but at the same time, due to structural needs, the pipeline often needs to be connected with the outer structure (such as the equipment casing, steel frame, etc.), that is, there are two fixed points on a straight pipe, then when the pipe is heated, the thermal stress between the two fixed points cannot be eliminated, which will lead to equipment damage

Moreover, some specific processes do not allow fixed connection such as welding and bonding between the pipe and the carrying device, so there will be leakage of granular materials in the gap between the pipe and the carrying device.
