Abstract
The invention discloses a quasi-continuous blanking type crust breaking and blanking method for an alumina electrolysis bath. According to the quasi-continuous blanking type crust breaking and blanking method disclosed by the invention, A and B groups of crust breakers and blanking devices are adopted for performing crust breaking and blanking on an aluminum electrolysis bath, namely one group comprises the A crust breaker and the A blanking device, the other group comprises the B crust breaker and the B blanking device, the A and the B groups of the crust breakers and the blanking devices are controlled to perform the crust breaking and the blanking on the aluminum electrolysis bath through a controller, a blanking interval exists between adjacent two actions, and the quasi-continuous blanking type crust breaking and blanking method comprises the following steps of: (1) blanking through the A blanking device after crust breaking through the A crust breaker; (2) only blanking through the A blanking device; (3) blanking through the B blanking device after crust breaking through the B crust breaker; and (4) only blanking through the B blanking device, so that crust breaking and blanking work of the aluminum electrolysis bath can be completed through the cycles. The quasi-continuous blanking type crust breaking and blanking method disclosed by the invention has the advantages of not only meeting blanking quantity within a same period of time and prolonging the service life of the crust breakers, but also having high working efficiency, convenience in transformation and capability of prolonging the service life of the crust breakers without increasing any investment.
Description
Technical field
The present invention relates to the crust breaking baiting method of the continuous blanking formula of a kind of standard alumina electrolysis bath, belong to the aluminum cell supplying technical field.
Background technology
At present; When in the prior art aluminium cell being carried out alumina blanking; Generally adopt one group or two groups of crust breaking machines and blanking device to carry out crust breaking and blanking; When adopting two groups of crust breaking machines of AB and blanking device that aluminium cell is carried out the crust breaking blanking, its mode of operation generally all is to carry out Control Circulation work according to the following steps through unit: 1., behind the A crust breaking machine crust breaking, the blanking of A blanking device, 2., behind the B crust breaking machine crust breaking, the blanking of B blanking device; Be again then 1., behind the A crust breaking machine crust breaking, the blanking of A blanking device, 2., behind the B crust breaking machine crust breaking, the blanking of B blanking device; Carry out crust breaking and blanking work so circularly.This mode of operation; For every group crust breaking machine, each blanking of this group blanking device all has a crust breaking action, hundreds of times of every group of blanking device blanking every day; The action frequency of every group of crust breaking machine is all also more than hundreds of times; So frequent action, causing the crust breaking machine fault is one of on-the-spot common equipment failure, so its maintenance capacity is very big.So existing alumina blanking mode still is not ideal enough.
Summary of the invention
The objective of the invention is to: provide a kind of and can satisfy the blanking amount, can prolong the crust breaking baiting method of the continuous blanking formula of the standard alumina electrolysis bath in crust breaking machine work-ing life again,, to overcome the deficiency of prior art.
The present invention is achieved in that the crust breaking baiting method of the continuous blanking formula of a kind of standard of the present invention alumina electrolysis bath; Comprise and adopt unit control crust breaking machine to carry out crust breaking, and carry out blanking, when every aluminium cell is carried out blanking through the aluminium cell of unit control blanking device after to crust breaking; Adopt two groups of crust breaking machines of AB and blanking device that it is carried out crust breaking and blanking; Promptly one group is A crust breaking machine and A blanking device, and another group is for B crust breaking machine and B blanking device, and controls two groups of crust breaking machines of AB according to the following steps and blanking device carries out crust breaking and blanking to aluminium cell through unit: 1., behind the A crust breaking machine crust breaking, the blanking of A blanking device; 2., an A blanking device blanking; 3., behind the B crust breaking machine crust breaking, the blanking of B blanking device, 4., the blanking of B blanking device, so just accomplished a crust breaking and blanking circulation; Then and 1., behind the A crust breaking machine crust breaking, the blanking of A blanking device, 2., the blanking of A blanking device, 3., behind the B crust breaking machine crust breaking, the blanking of B blanking device, 4., the blanking of B blanking device; So circulation can be accomplished crust breaking and blanking work to aluminium cell.
Since adopted technique scheme, for every among the present invention crust breaking machine, per twice blanking of this group blanking device; Just make a call to shell one time; Therefore the traditional relatively crust breaking cutting mode number of times of action frequency of every group of crust breaking machine reduces by half, and the interval of each group blanking device blanking and last crust breaking be a blanking at interval, prove through test and actual the use; The present invention can not cause the card of aluminum cell shell face pinkeye stifled, the not smooth situation of blanking can not occur yet.So; The present invention compared with prior art; The present invention not only has the blanking amount that in the identical time, can satisfy, can prolong the crust breaking machine advantage in work-ing life again, can prolong the crust breaking machine advantage in work-ing life but also have high efficiency, transformation convenience and do not increase any investment.
Embodiment
Below in conjunction with embodiment the present invention is done further detailed description.
Embodiments of the invention: the crust breaking baiting method of the continuous blanking formula of a kind of standard of the present invention alumina electrolysis bath need not increase any device when implementing can directly transform enforcement on existing equipment; This method comprises that adopting existing unit to control crust breaking machine carries out crust breaking; And carry out blanking through the aluminium cell of unit control blanking device after to crust breaking, when every aluminium cell is carried out blanking, adopt two groups of crust breaking machines of AB and blanking device that it is carried out crust breaking and blanking; Promptly one group is A crust breaking machine and A blanking device; Another group is for B crust breaking machine and B blanking device, and during enforcement, the each blanking time of each crust breaking time and every blanking device that makes every crust breaking machine through unit is all with of the prior art the same; And control two groups of crust breaking machines of AB according to the following steps and blanking device carries out crust breaking and blanking to aluminium cell through unit; Between each action be a blanking at interval: 1., behind the A crust breaking machine crust breaking, the blanking of A blanking device, 2., the blanking of A blanking device, 3., behind the B crust breaking machine crust breaking, the blanking of B blanking device; 4., the blanking of B blanking device, so just accomplished a crust breaking and blanking the circulation; Then and 1., behind the A crust breaking machine crust breaking, the blanking of A blanking device, 2., the blanking of A blanking device, 3., behind the B crust breaking machine crust breaking, the blanking of B blanking device, 4., the blanking of B blanking device; So circulation can be accomplished crust breaking and blanking work to aluminium cell.
