Round-link chain sand-blasting machine

Abstract

The invention discloses a round-link chain sand-blasting machine. The round-link chain sand-blasting machine consists of a transmission unit, a shock excitation unit, a sand-blasting unit, a sand recycling unit, a sealing unit and a sand-blasting room. In work, a round-link chain enters the sand-blasting room from an inlet through a left side sealing unit, and enters a vibrating hopper of the shock excitation unit; the round-link chain keeps a pre-feeding section with certain length in the vibrating hopper by controlling drive chain wheels at the two ends of the vibrating hopper; the shock excitation unit applies shock to the pre-feeding section, so that the posture of the pre-feeding section is transformed, and therefore, the shock excitation unit is mutually separated from the pre-feeding section to form a seam; meanwhile, sand-blasting is applied to the pre-feeding section through a spray gun arranged above, so that abrasive materials can smoothly enter the seam to avoid a sprayingleakage phenomenon; after operation requirements are met, the pre-feeding section leaves the vibrating hopper and operates to the outside of the sand-blasting room through a sealing unit at an outlet,and the round-link chain subsequently enters the vibrating hopper. The round-link chain sand-blasting machine can perform continuous sand-blasting treatment on the too long round-link chain in a sealed environment, and solves the technical problems of low efficiency, easy spraying leakage, a great site area, great labor intensity and severe pollution in existing sand-blasting operation of the toolong round-link chain.

Description

technical field [0001] The invention relates to the field of surface treatment of circular chains, in particular to a continuous sand blasting machine for circular chains. Background technique [0002] At present, the equipment used for mechanical surface treatment (surface derusting and pre-plating treatment) of circular link chains is mainly a drum type sandblasting room, which can handle relatively short circular link chains, and in the face length And larger circular link chains, such as anchor chains for mooring, scraper conveyors and coal plows and other mining circular chains, and bridge circular chains, because their length is usually more than hundreds of meters, so the As a result, the size of the sandblasting room equipment is too large, and the requirements for the powertrain are also significantly increased, which is difficult to achieve. [0003] For the anchor chain, the total length is often more than 500 meters, and its surface is sandblasted to decontamina...
