An energy-saving pipeline inner wall shot blasting derusting machine

Abstract

The invention relates to an energy-saving pipe inner wall shot blasting rust remover. The rust remover is composed of an electric rotation blasting head with blades, a grit delivery worm device, a worm sleeve pipe, a steel grit recovery device, a grit supply box, a sealing device, a grit guiding device, a grit feeding device, a movable trolley, a movable trolley motor, a rotary roller, a rotary roller motor, a rail, and the like. The electric rotation blasting head with blades is connected with the worm sleeve pipe through a connector. The rotatable grit delivery worm device is arranged in the worm sleeve pipe. The grit delivery device can rotate forwardly and reversely under the effects of a motor and a reducer. When the grit delivery device rotates forwardly, grit is fed, and when the grit delivery device rotates reversely, grit is recovered. The grit feeding device is arranged in the grit supply box, such that steel grit can be recycled and reused. With the scheme provided by the invention, large amount of mechanical parts and materials can be saved, and large amount of power energy can be saved during working. Therefore, pipe rust removal work is energy-saving and highly efficient.

Description

technical field [0001] The invention relates to a shot blasting rust removal machine for the inner wall of a large-diameter pipeline, in particular to an energy-saving shot blasting rust removal machine for the inner wall of a pipeline, which belongs to the field of metal processing rust removal. Background technique [0002] At present, to solve the problem of rust removal on the inner wall of steel pipes, most of the rust removal methods such as steel grit and steel shot are projected or sprayed. Pill derusting machines use a large electric motor with power consumption of hundreds of kilowatts to drive a set of huge hydraulic motor high-speed rotating blades to blast sand and derust the inner wall of the steel pipe. For steel grit recovery and sand supply equipment, in order to clean the steel grit from the steel pipe, a fan that consumes a lot of power must be used to pull the steel grit and dust from the pipe, and then send the steel grit to the steel grit through the sa...

[0002] At present, to solve the problem of rust removal on the inner wall of steel pipes, most of the rust removal methods such as steel grit and steel shot are projected or sprayed. Pill derusting machines use a large electric motor with power consumption of hundreds of kilowatts to drive a set of huge hydraulic motor high-speed rotating blades to blast sand and derust the inner wall of the steel pipe. For steel grit recovery and sand supply equipment, in order to clean the steel grit from the steel pipe, a fan that consumes a lot of power must be used to pull the steel grit and dust from the pipe, and then send the steel grit to the steel grit through the sand and ash separation device In the circulation system, the dust is sent to the dust removal system. This traditional shot blasting machine causes a lot of waste of electricity, manpower and materials. Therefore, people need a new energy-saving pipe inner wall blasting machine that can overcome the above defects. Pill derusting machine
