Description
技术领域 technical field
本实用新型涉及电解铝行业、铸造涂料喷涂设备领域，特别涉及一种铝电解碳素阳极保护涂料用喷涂机。 The utility model relates to the field of electrolytic aluminum industry and casting paint spraying equipment, in particular to a spraying machine for aluminum electrolytic carbon anode protective paint.
背景技术 Background technique
在电解铝行业中，增加碳素阳极的利用率，减少阳极的氧化消耗，是降低电解铝生产成本的最直接的方式。从理论上讲每生产一吨铝要消耗碳量333kg，而铝厂实际消耗的碳量为500～600kg，约占总成本的15%左右。对于一个年产50万吨电解铝产能的企业而言，如果阳极单耗降低5kg/t-Al，以阳极块成本4000元/吨计，则企业年度节本增效1000万元，目前已研制出的碳素阳极用抗氧化、耐腐蚀涂料，能够减少碳素阳极石墨的氧化和腐蚀，有效延长其使用时间，大大降低电解铝的生产成本。碳素阳极保护涂料已经在包铝、银川铝业、青海铝业和重庆铝业等多家大型电解铝厂进行了生产中试，结果表明：阳极保护涂料的应用对减少阳极的氧化与腐蚀，延长碳素阳极的使用时间有明显效果，能够大幅降低电解铝厂的生产成本。但同时也发现了严峻的问题，就是该涂料的涂覆方法是其能否成功推广应用的关键。 In the electrolytic aluminum industry, increasing the utilization rate of carbon anodes and reducing the oxidation consumption of anodes is the most direct way to reduce the production cost of electrolytic aluminum. Theoretically, 333kg of carbon is consumed for producing one ton of aluminum, but the actual carbon consumption of an aluminum factory is 500-600kg, accounting for about 15% of the total cost. For an enterprise with an annual production capacity of 500,000 tons of electrolytic aluminum, if the anode unit consumption is reduced by 5kg/t-Al, based on the anode block cost of 4,000 yuan/ton, the company's annual cost savings and efficiency increase will be 10 million yuan. The anti-oxidation and corrosion-resistant coatings for carbon anodes can reduce the oxidation and corrosion of carbon anode graphite, effectively prolong its service life, and greatly reduce the production cost of electrolytic aluminum. Carbon anode protective coatings have been tested in a number of large-scale electrolytic aluminum plants such as Baolu, Yinchuan Aluminum, Qinghai Aluminum and Chongqing Aluminum. The results show that the application of anodic protective coatings can reduce the oxidation and corrosion of the anode Prolonging the use time of carbon anodes has obvious effects, which can greatly reduce the production cost of electrolytic aluminum plants. But at the same time, a serious problem has also been found, that is, the coating method of the coating is the key to its successful promotion and application.
目前涂料在工件表面涂覆的方法有流涂、浸涂、喷涂和刷涂四种，流涂和浸涂显然不适用于阳极保护涂料，在目前涂料喷涂设备尚不完善的情况下，对阳极保护涂料只能采取人工刷涂的方法，每个工人一天能刷涂5～6组阳极，而且劳动强度极大。对于一个年产50万吨电解铝的企业，每天需要更换至少800组阳极，如要满足生产要求，企业则需雇佣120～150人才能完成涂料涂刷的工作，而因此产生的人工成本、管理成本和场地成本的增加是任何企业不能接受的。然而目前市场上现有的喷涂设备均不能满足碳素阳极保护涂料的喷涂要求，要想将碳素阳极保护涂料在电解铝行业进行大面积推广，必须研发其专用喷涂设备。 At present, there are four methods of coating coating on the workpiece surface: flow coating, dip coating, spray coating and brush coating. Flow coating and dip coating are obviously not suitable for anode protection coatings. The protective paint can only be painted manually, and each worker can paint 5-6 sets of anodes a day, and the labor intensity is extremely high. For an enterprise with an annual output of 500,000 tons of electrolytic aluminum, at least 800 sets of anodes need to be replaced every day. To meet the production requirements, the enterprise needs to employ 120 to 150 people to complete the work of painting, and the resulting labor costs, management The increase of cost and site cost is unacceptable for any enterprise. However, none of the existing spraying equipment on the market can meet the spraying requirements of carbon anode protection coatings. In order to promote carbon anode protection coatings in the electrolytic aluminum industry on a large scale, it is necessary to develop its special spraying equipment.
