The invention discloses a sealing and partition device for an air-tight high-density granular material. The device is arranged at the opening end of an air-tight container and comprises a valve body with a channel, wherein the channel is the same as the air-tight container; a valve plate capable of unfolding and folding is arranged inside the channel; and a covering structure which partially covers the channel is also arranged in the channel above the valve plate. The device is arranged below the container with the air-tight stored high-density granular material and is used for accommodating the material, so that the problem of accommodating the material by using the container with the air-tight stored high-density granular material is solved radically.
Description
A closed partition device for airtight high-density material granular materials technical field The invention relates to the field of airtight storage of high-density granular materials, in particular to a special butterfly valve device. Background technique In order to enable the container with airtight storage of high-density granular materials to perform discharge operations, a valve device must be installed at the bottom of the container. However, the existing common butterfly valves are simple in structure and often cannot be opened normally during use. Contents of the invention The technical problem to be solved by the present invention is to overcome the problems existing in the prior art and provide a closed partition device for airtight high-density granular materials, which can meet the requirements of storing high-density granular materials. The airtight requirements of the material container can be met, and the normal discharge operation can be realized. ...
