Abstract
The utility model relates to a preheating exchanging device of anode blocks, which is a box type structure, wherein a row of anode scrap tray supports are arranged on the bottom surface, new anode tray supports are respectively arranged above every two adjacent anode scrap tray supports, an anode guiding rod guiding groove is arranged on the top of a corresponding box body above the new anode tray supports and the anode scrap tray supports, and a sealing door is arranged on the front surface of the box body. The device has simple structure, convenient and simple operation and safety, the temperature of new anodes can reach 80 DEG C after preheating, and is directly arranged in an electrobath, which can avoid the generation of physical injury accidents because of triggering explosion, can totally guide current in advance by 2-3 hours and can reduce the electrical consumption by 20-30 kWh per ton of aluminum per when using the preheating new anodes. The acute stirring of the electrobath can not be generated because that a wet pole block meets molten electrolyte and aluminum liquid, which generates the voltage vibration, the temperature of the electrobath is sharply reduced after a cooling state anode seats in, which solidifies the circumference of the anode, enables the electricity conduction of the anode to be poor, and affects the stable operating state of the electrobath, and the device is beneficial to improve the current efficiency and reduce the production cost.
Description
Technical field
The utility model relate to a kind of in the aluminum smelting technology process in order to save the energy, the device that anode new utmost point carbon piece and anode anode scrap carbon piece are carried out pre-heat exchange.
Background technology
Need to carry out the anode exchange in the Aluminum Electrolysis Production process, both extract the low level anode scrap and taken the new utmost point, and the segment anode humidity that Aluminum Electrolysis Production is used, ionogen splashes when causing anode to be seated in the electrolyzer, and the boiling of anode periphery was violent, for up to more than 2 hours, not only influence operational quality, voltage raises during this time, the pin increase of shaking, thus influence electrolyzer steady running.Moist anode is seated in not only hydrolysis ionogen generation hydrogen fluoride gas deterioration environment of electrolyzer, but also might be explosion caused, easily causes the generation of personal injury accident.In addition, the anode scrap temperature of extracting to producing thermal radiation on every side, influences the work on the spot environment up to 950 ℃.And new anode is seated in electrolyzer, and the temperature that progressively is elevated to the electrolysis ordinary production from normal temperature also needs a large amount of heat supplement, when the new utmost point is seated in the electrolyzer, cold resistance is big, and it is poor to conduct electricity, 16 hours conductive capabilities only 70%, cause the distribution of current inequality, disturb very big electrolyzer production.The factor that causes the electrolysis groove pin to shake according to statistics has over half from behind the change poles.If resistance is reduced anode preheating before the change poles, increase conduction, then help the stable of cell technologies condition.Therefore, the anode that urgent hope is seated in electrolyzer is not moist, preferably the anode after the heating.
Summary of the invention
The technical problems to be solved in the utility model is: design the pre-heat exchanger of a kind of anode block, new anode block and the anode block of extracting are carried out pre-heat exchange in this device, new anode block is shifted to an earlier date preheating, dry its moisture, the influence that minimizing causes because of humidity or cold conditions anode to the technical qualification of electrolyzer, the conduction time behind the groove is newly extremely gone up in shortening, improves Working environment, improves work quality.
The technical scheme that solution the utility model problem is taked is: design the pre-heat exchanger of a kind of anode block, this device is a case structure, each side box wall of casing is made by lagging material, on the casing inner bottom surface, be provided with row's anode scrap tray supporter, new utmost point tray supporter is located at per two adjacent anode scrap tray supporter tops, and corresponding casing top is provided with the anode rod guide groove above new utmost point tray supporter and anode scrap tray supporter; A hermatic door is installed in the casing front.
Anode is put into casing for convenience, and the longitudinal section of casing is a right-angled trapezium, and promptly the front of casing is sweptback domatic.
Positively effect of the present utility model is: simple in structure, and less investment, simple to operate, safety; Temperature can reach 80 ℃ after the new utmost point preheating, avoided because of the anode block humidity directly is seated in the groove, and the explosion caused generation that causes personal injury accidents; Can lead total current in advance and shorten 2-3 hour, preheating aluminium newly extremely per ton can reduce power consumption 20-30kWh; The new utmost point after the preheating is seated in the groove, electrolyzer is met fused ionogen and the violent stirring of aluminium liquid with regard to not occurring because of utmost point piece humidity, pin shakes after producing change poles, or the cold conditions anode is seated in afterwards, and electrolyte temperature sharply descends, solidify around the anode, cause anode non-conductive bad, influence electrolyzer steady running, can help improving current efficiency.
