Scrapped humid welding rod recovery processing device

Abstract

The invention relates to the technical field of welding rod recovery, in particular to a scrapped humid welding rod recovery processing device. The recovery processing device comprises a machine body and a drying block located in the machine body, wherein a conveying cavity with an opening in the left and right is formed in the drying block, a first valve is arranged in the end wall of the right side of the conveying cavity, and two groups of symmetrical dryers are fixedly arranged on the inner wall and the outer wall of the conveying cavity. According to the scrapped humid welding rod recovery processing device, hot flow gas is introduced into a heating cavity through a gas pump to dry the surfaces of humid welding rods, the coating on the surfaces of the welding rods is scraped off through contact between coating rollers which are symmetrical left and right and the welding rods, a friction plate conducts friction extrusion between welding powder blocks to enable the powder to be evenly scraped off from the surface to the welding rods, the powder is leveled evenly through a smearing roller, after smearing, the welding rods are led into bonding liquid through an air pressure valve, heating gas in the heating cavity is matched to enable the coating powder on the surface of the welding rod to be bonded firmly, and the coating powder is prevented from falling off.

Description

technical field [0001] The invention relates to the technical field of welding rod recycling, in particular to a recycling and processing device for scrapped wet welding rods. Background technique [0002] The welding rod is composed of two parts: the welding core and the coating. The welding rod is to apply the coating evenly and centripetally to the welding core outside the metal welding core. Different types of welding rods have different welding cores. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially the content of harmful impurities. [0003] Due to the base metal, in the actual production process, we usually manually remove the coating on the scrapped electrodes, and then recycle the welding core, but the efficiency of manual removal of the coating is low, and the electrodes after removing the coating are ...

AI Technical Summary

Problems solved by technology

[0003] Due to the base material, in the actual production process, we usually manually remove the coating on the scrapped electrodes, and then recycle the welding core, but the efficiency of manual removal of the coating is low, and the electrodes after removing the coating are randomly stacked In the case of taking up a lot of space, it is also prone to danger. Therefore, in order to ensure that the electrode can continue to be used after removing the coating, it is necessary to evenly coat the surface of the electrode with solder powder. In some environments with low temperatures, due to the powder and The surface temperature of the welding rod is low, and the solder powder applied on it is easy to fall off due to poor plasticity and viscosity. Therefore, it is necessary to design a recycling and processing device for scrapped wet welding rods to improve the above problems
