Description
Technical field
The utility model belongs to the aluminium cell technical field, is specifically related to a kind of aluminium cell raw material preheating device.
Background technology
Aluminum electrolysis needs hot conditions, and the preheating meeting of raw alumina produces great effect to the electrolysis of aluminum acting.In electrolytic aluminum crust breaking blanking process, the aluminium cell electrolysis temperature up to 940 ℃～960 ℃, the shell hole temperature behind the crust breaking is very high; Existing aluminum oxide point feeding device cutting mode is that raw material gets into electrolyzer from the hopper feed opening after the crust breaking work; And this hopper is far away apart from electrolyzer, so the heat that distribute in the shell hole is less to the influence of the material temperature in the hopper, and the aluminum oxide temperature that gets in the electrolyzer is low; Needing to absorb a large amount of heat could dissolve; Expend the energy, and that waste heat utilizes is low again, causes calorific loss.
Application number is 200820218813.8 (patent names: a kind of aluminum electrolyzing cell used built-up type crust breaking tremie pipe; Publication number: 201309969; The open date: Chinese granted patent on September 16th, 2009) discloses a kind of built-up type crust breaking tremie pipe; The tremie pipe of electrolyzer blanking system was communicated with the attacking head protective sleeve of crust breaking system before getting into the shell hole, it is transformed into built-up type crust breaking tremie pipe.Use the difference of this built-up type crust breaking tremie pipe and this patent to be: following shortcoming is arranged: (1), enclosed appts is not arranged at tremie pipe feed opening place; Raw material still directly gets in the electrolyzer; Can not effectively utilize the electrolyzer waste heat, play preheating effect raw material; (2), the crust breaking end protective sleeve is a long and narrow annular cover, after the crust breaking end protective sleeve was joined with tremie pipe, raw material blocked in the crust breaking end protective sleeve easily, caused the increase of crust breaking end and protective sleeve frictional force, thereby influenced crust breaking end work, the damage crust breaking end; (3), blanking equipment and the operation of crust breaking device separates, connect blanking equipment and crust breaking protective sleeve with tremie pipe, the blanking process extends, and causes blanking in time, influences working efficiency.
The utility model content
The purpose of the utility model is the above shortcoming that overcomes the crust breaking blanking device of plain electrolysers, and a kind of crust breaking blanking device with raw material preheating effect is provided.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is following:
A kind of raw material preheating device that is used for electrolyzer installs the hollow container of a upper and lower opening additional at hopper feed opening place, hollow container is fixed on that crust breaking end is arranged in hollow container on the electrolyzer feed opening cell body, and hollow container lower ending opening place is provided with tightness system.
Further, tightness system is a portable plate, and portable plate and hollow container lower ending opening flexibly connect.
Further, said tightness system is a baffle plate, and baffle plate is fixedly connected with crust breaking end, and the size of baffle plate is not less than the size of said hollow container lower ending opening.
The beneficial effect of the utility model is, adopt above technical scheme after:
1, the present technique scheme has installed the hollow container of a upper and lower opening additional at hopper feed opening place, and is being provided with the lower opening that tightness system comes the sealed hollow container, and raw alumina is stored hollow container earlier after hopper comes out; Because this storing device is near apart from the shell hole; Effectively absorption electrolysis groove heat carries out raw material preheating, when crust breaking end work next time, gets into electrolyzer again, raw alumina is played the effect of secondary storage preheating; Reduce energy loss; After the preheating, the dissolution rate of aluminum oxide shortens, and avoids producing bearth precipitation.
2, in the present technique scheme, because hollow container is near apart from the electrolytic bath shell hole, after the raw material in the hollow container absorbs heat, can be liquefied as stream shape object, in crust breaking end work, can not cause raw material to scatter, economize on resources, avoid dust.
3, described hollow container capacity is bigger, and blanking is fast, can not hinder crust breaking end work, can not cause damage to crust breaking head protection cover and crust breaking end, and can in time in time carry out blanking to the raw material of preheating, has improved working efficiency.
