Abstract

The invention mainly relates to a groove body feeding and discharging device with easy material incrustation, in particular to an incrustation breaking device for an electrolysis bath or an electroplating bath. A scraping type incrustation breaking device comprises a flange (2) which is connected with a groove body mounting beam (4) and is arranged on an incrustation pressing cylinder or an incrustation breaking cylinder (1), and a hammer rod (8) connected with the end part of a cylinder piston (1-1); and the lower end of a cylinder sleeve (1-2) is connected with a guide cylinder (7), and thehammer rod moves upwards and downwards in the guide cylinder (7). The groove body feeding and discharging device is mainly characterized in that the lower ends of the guide cylinder (7) and the hammer rod (8) are provided with scaffolding and scraping devices (11); and the lower end part of the hammer rod (8) is connected with a hammer head (12) which is made of austenitic stainless steel. The groove body feeding and discharging device overcomes the defects of the prior incrustation breaking device for an aluminum electrolysis bath so that electrolyte scaffoldings on the surface of the hammerhead of the incrustation breaking device need not be beaten away manually, and the phenomena that the hammer head is fractured and falls into aluminum liquid in the electrolysis bath can be precluded. The groove body feeding and discharging device increases insulating points, improves the insulating reliability, and solves the problem of abnormal spoilage of the cylinder. At the same time, the groove body feeding and discharging device solves the sealing problem of the incrustation breaking device and the upper structure of the electrolysis bath, and the problems of fast hammer replacement and no maintenance of a mechanism.

Description

Technical field: [0001] The invention mainly relates to a tank body feeding and discharging device for materials that are prone to crusting, in particular to a shelling device for an electrolytic cell. Background technique: [0002] At present, in the production of aluminum electrolysis, alumina is added densely and in small amounts to the electrolytic cell through a quantitative feeder, and the alumina whose weight is determined by the process parameters is added to multiple feed holes within a specified time interval. However, since there is a layer of hard electrolyte crust on the surface of the molten electrolyte in the electrolytic tank, it must be broken by the shell breaking device of the electrolytic tank before feeding to form a feeding port. [0003] At present, in the electrolytic cell shelling device used in the electrolytic aluminum production industry, during the shelling process, the lower surface of the hammer head will adhere to the electrolyte liquid, solid...
