Abstract
The utility model discloses a settling tank with a scab cleaning function. The settling tank comprises a settling tank body, wherein the top part of the settling tank body is provided with an alkali liquor feed pipe and a steam pipe; the bottom part of the settling tank body is provided with a bottom flow circulating pipe; one end of the bottom flow circulating pipe is connected at the bottom of the settling tank body and the other end of the bottom flow circulating pipe is connected at the top of the settling tank body, and a bottom flow pump is arranged on the bottom flow circulating pipe; and an alkali liquor discharge pipe is also connected to the bottom flow circulating pipe. By adoption of the settling tank with the scab cleaning function, the cleaning cost can be saved, the cleaning period is shortened, and aluminum oxide in the scab is recovered. In the process of washing the settling tank by alkali, the scabs of the surfaces of equipments such as a blanking well, a pipeline and a valve are also cleaned.
Description
Technical field
The utility model belongs to the aluminium oxide field of smelting, relates in particular to a kind of subsider with the clearing function that scabs.
Background technology
In the aluminum oxide production process, the pipeline of convey materials and groove tank inwall can constantly produce and scab along with the carrying out of various chemical reactions.The red mud separating, washing operation is to scab in the aluminum oxide production process to generate the fastest zone, these normal operations that seriously restriction is produced that scab.The cleaning that existing subsider scabs is fully by the labor cleaning, and long expense of time is high and scab and can't reclaim.
The utility model content
The purpose of this utility model is exactly the problem that exists for prior art, and a kind of subsider with the clearing function that scabs is provided.
Above-mentioned purpose realizes by following proposal:
A kind of subsider with the clearing function that scabs, it comprises the subsider cell body, it is characterized in that, is provided with alkali lye feed tube and steam pipe at described subsider cell body top; Underflow pump outlet in described subsider cell body bottom is equipped with the underflow circulation pipe, and an end of this underflow circulation pipe is connected to described subsider cell body bottom, and the other end is connected to the top of described subsider cell body; On described underflow circulation pipe, also be connected with the alkali lye liquid discharging tube.
The beneficial effects of the utility model: the utility model can have been saved cleaning up cost, has shortened the cleaning duration, has reclaimed the aluminium oxide in scabbing.In the process of alkali cleaning subsider, the equipment surface such as blanking well, pipeline and valve scab and have also obtained cleaning.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the subsider with the clearing function that scabs of the present utility model comprises subsider cell body 1, and subsider cell body 1 top is provided with alkali lye feed tube 2 and steam pipe 3; Underflow pump 5 outlets in subsider cell body 1 bottom are equipped with underflow circulation pipe 4, and an end of underflow circulation pipe 4 is connected to subsider cell body 1 bottom, and the other end is connected to the top of subsider cell body 1; On the underflow circulation pipe, also be connected with alkali lye liquid discharging tube 6.
The process of carrying out alkali cleaning is as follows:
With after the subsider isolation of alkali cleaning, deployed heat alkali liquid enters in the subsider from groove top alkali lye feed tube 2, open underflow pump 5, alkali lye enters in the groove from the groove jacking by underflow circulation pipe 4, form circulation in the groove, in the alkaline cleaning procedure per 8 hours from underflow pump 5 sample analysis, stop alkali cleaning very little the time when the composition of aluminium oxide in the alkali lye changes.Salkali waste can be sent to ball mill as batching by alkali lye liquid discharging tube 6., scab in the groove and can clean generally through 3～5 days circulation alkali cleaning according to the situation that scabs of subsider.In order to keep the temperature of alkali in groove liquid, the valve that needs in the circulation alkaline cleaning procedure to open steam pipe 3 leads to the vapour insulation in groove.
The alkali cleaning operating condition:
