Description

Lining fastening device and method for aluminum electrolysis cell Technical Field The invention relates to the field of electrolytic tank equipment, in particular to an aluminum electrolytic tank lining fastening device and method. Background The electrolytic tank is core equipment for producing electrolytic aluminum, the lining binding of the aluminum electrolytic tank is a particularly critical process in the furnace building process of the electrolytic tank, the lining binding of the aluminum electrolytic tank needs to be bound by a plurality of layers of paste, and the production capacity, the operation stability and the service life of the electrolytic tank are directly determined by the quality of the paste binding. In the prior art, most of the electrolytic tank binding operation adopts an artificial cloth and construction mode, a 10-person professional tamping hammer is used for tamping a vertical seam, a side seam and an artificial extending leg of a carbon block through an air hammer, and about 10-person iron shovels are used for feeding and distributing materials, wherein the traditional cloth scraping method is to manually add paste into a gap (the width is 30-35 mm, the depth is more than or equal to 450 mm) of a cathode carbon block, then manually scrape the paste by a scraper smaller than the gap in size, the mode has the defects of more requirements of constructors, time and labor waste in operation, poor construction environment, high labor intensity and the like, and because the gap between cathode carbon blocks is narrow and deep, the manual scraping can only be realized through experience or feel, and the binding quality stability is poor. In addition, some devices for fastening an electrolytic tank are also disclosed in the prior art, but the electrolytic tank fastening device in the prior art generally distributes materials into gaps of the cathode carbon blocks, then directly performs a strickling operation on the cathode carbon blocks by utilizing a scraping plate or a fastening hammer and the like, finally performs a strickling operation by utilizing the fastening hammer, for example, patent with the publication number of CN101274446B discloses a multi-hammer electrolytic tank tamper, which comprises a cart running mechanism and a cart running mechanism, wherein the cart running mechanism is provided with a feeding mechanism and a blanking barrel, a distributing hopper is hung at the lower end of the blanking barrel and is used for inputting paste into corresponding carbon gaps, scraping plates which can stretch up and down are respectively arranged at two sides below the blanking barrel, the scraping plates descend and strickling the paste along with movement of the cart after the blanking is finished, and finally the tamping is performed. In another patent, for example, CN108286062B discloses a cathode carbon block gap cloth fixing device and a fixing method, the device starts a small end beam to drive a paste guiding tube to move along a left-right direction to fill paste into a gap, then starts the small end beam to drive a fixing hammer to be used as a scraping plate to scrape the paste, and finally starts a big end beam to drive a fixing gun to move to fix the paste in the gap. The device has the defects that the carbon block gaps are narrow and deep, so that the uniform distribution is difficult to ensure, namely, the situation that a part of paste is more and the other part of paste is less in the carbon block gaps is easy to occur, the uniform binding and the binding quality are difficult to ensure in the follow-up binding, in addition, the paste overflows easily at the two sides of the carbon block gaps, and the inaccurate distribution is easy to cause. Disclosure of Invention The invention aims to provide an aluminum electrolysis cell lining binding device and method, which can realize automatic material distribution and binding, accurately control the material distribution amount through a weighing device during material distribution, then input paste into a material groove in a hopper and directly carry out strickling operation in the material groove, so that the paste in each part in the material groove can be ensured to be uniformly distributed, then the material groove is turned over to pour the paste into a carbon block gap, and further, the uniform material distribution of each part in the carbon block gap is ensured, in addition, the material baffle plates at two sides of the hopper can also block two sides of the carbon block gap to avoid overflow of the paste during material distribution, and the accurate material distribution amount control can be ensured. The aim of the invention is realized by the following technical scheme: The utility model provides an aluminum electrolysis cell lining is pricked and is fixed device, includes Y to remove portal, X to remove frame and hopper, wherein X to remove the frame and locate Y to remove the portal on, and X to remove
