The invention provides a
calcium carbide lifting hopper, and belongs to the technical field of
acetylene preparation equipment. In order to solve the problem that in the prior art, the abutting jointbetween a lifting hopper and a
calcium carbide feeding hopper is difficult, the
calcium carbide lifting hopper is provided. On the basis of the following scheme, the
calcium carbide lifting hopper comprises a cylindrical hopper body. A funnel-shaped material falling portion is arranged on the lower portion of the hopper body, a feeding inlet is formed in the upper portion of the hopper body, a material falling opening with a
butterfly valve is formed in the bottom of the material falling portion, and at least three lifting portions are arranged on the upper portion of the hopper body and closely attached to the outer wall face. A high-strength cloth cylinder is fixedly connected with the lower portion of the material falling opening, and a first annular permanent
magnet is fixedly connected with the
tail end of the high-strength cloth cylinder. The
calcium carbide lifting hopper further comprises auxiliary parts, wherein the auxiliary parts are fixedly arranged in a feeding inlet of the
calcium carbide feeding hopper. The auxiliary parts comprise a second annular permanent
magnet and pneumatic fasteners, wherein the second annular permanent
magnet is fixedly arranged in the feedinginlet of the calcium carbide feeding hopper, and the pneumatic fasteners are used for fastening the first annular permanent magnet and the second annular permanent magnet. The pneumatic fasteners areconnected with air cylinders, the air cylinders are fixedly arranged on the periphery of the feeding inlet of the calcium carbide feeding hopper, and therefore the problem is solved.
