Expansion booster

Abstract

The invention provides an expansion booster. The expansion booster comprises a cone head and an operating rod connected with the cone head, wherein the cone head is in the shape of a cone; the bottom face of the cone head is provided with a containing cavity; the side wall of the containing cavity is provided with a first clamping block and a second clamping block in a spaced manner in the generatrix direction of the cone head; the second clamping block is closer to the front end portion of the cone head than the first clamping block; the side face of the cone head is provided with a plurality of anti-rotating grooves communicated with the containing cavity in a spaced manner in the circumferential direction; each anti-rotating groove penetrates the bottom face of the cone head and divides the cone head into a plurality of expansion blocks; the end, facing the cone head, of the operating rod is provided with a containing block which is contained in the containing cavity; and a clamping groove buckled with one of the second clamping block and the first clamping block is formed in the containing block. By means of the expansion booster, matter adhering to the bottom of a chute can be fast eliminated as a whole.

Description

technical field [0001] The invention relates to the technical field of chute-clearing and flow-aiding devices, in particular to an expansion booster for removing residual sticky matter in chutes in smelting equipment. Background technique [0002] The chute is an important link between various equipment in the smelter, and plays a vital role in the transportation and reloading of minerals. The normal flow of minerals in it is directly related to the stability of the entire production system. When the chute is transporting minerals, because the bottom of the chute is blocked by sulfur slag and other adhesives, there are materials left in the chute. Generally, the metal rods are used to pierce the materials and then hit the adhesives. Generally, the materials in the chute are relatively solid. In order to reduce resistance, The diameter of the metal rod that needs to be impacted and pierced through the material must not be too thick, and the disadvantage is that after the meta...
