Air cannon block-removing equipment of micro-recoil

Abstract

The invention discloses a micro-recoil air cannon blockage remover for loosening blocked bulk materials in silos of mines or metallurgy or coking industries. Compressed air enters the cylinder cavity through the air delivery pipe at the outlet of the reversing valve, the one-way valve into the air storage pipe, the air intake pipe, and the plunger screw tube, and the cylinder air intake pipe connected to the air outlet pipe on the side of the air storage end extends into the cylinder body. Cavity, there is a blast tube at the opening on one side of the cylinder block, there are sealing rubber rings, pressure plates, connecting bolts and sealing rings at both ends of the piston cylinder, and there are gland nuts and buffer rubber rings on the threaded section or end section of the plunger screw. When blasting the bulk blocked materials in the silo, operate the reversing valve so that the compressed air in the cylinder body passes through the intake pipe and then is released by the reversing valve, and the compressed air in the intake pipe of the cylinder pushes the piston cylinder to move to the left at high speed And enter the silo through the blasting tube to clear the bulk materials. The service life of this plug remover can be increased by 5-10 times.

Description

technical field [0001] The invention relates to a blockage remover, in particular to a micro-recoil air cannon blockage remover which is used to loosen blocked bulk materials in silos used for storing bulk materials in mines or metallurgical or coking enterprises. Background technique [0002] For example, dolomite or limestone bulk materials mined in non-metal mines, iron ore powder mined in metal mines, and coal powder used for coal blending in coking enterprises basically enter their respective silos before use, and then open each according to the amount required. The discharge port of the silo transports bulk materials to various use sites. The bulk materials in the silo can be removed from the silo according to the dosage requirements when the logistics is smooth. If there is a material blocking accident (especially when the material contains moisture), they will neither be removed on time and in accordance with the amount, or even block the silo. . Before the present...

AI Technical Summary

Problems solved by technology

Before the present invention, in order to solve the problem of material blocking in the silos, an air cannon device was also used to dredge the storage materials in each silo so that the materials could be removed from the silos in time. During this period, the blocked material in the silo is loosened. The disadvantage is that there is a spring in the inner cavity between the cylinder block and the gland. Although this spring can play a role in positioning and buffering, it is easily broken under strong and repeated impacts. The entire blockage remover is scrapped, and the equipment is replaced frequently, which increases the equipment cost of the enterprise
