Abstract
The invention discloses an electrolytic bath feed box exhausting and self-locking device which comprises a feed box (1), a feed box upper cover (2) connected with the upper end of the feed box (1), and an exhaust pipe (3) as well as a discharging pipe (4) which are longitudinally arranged in the feed box (1), wherein the position of the upper end of the discharging pipe (4) is higher than the feedbox upper cover (2). The device is characterized in that the upper end of the feed box upper cover (2) is connected with a pipe sleeve (5); the exhaust pipe (3) extends into the pipe sleeve (5) by pa ssing through the feed box upper cover (2); and the upper end of the discharging pipe (4) is positioned outside the pipe sleeve (5). As the mode that the pipe sleeve is sheathed on the exhaust pipe, the device greatly raises the height of the exhaust pipe, and materials can hardly enter the electrolytic bath through the exhaust pipe along with gas, thus greatly stabilizing electrolytic production.
Description
Technical field
The present invention relates to be installed in a kind of aluminum electrolysis exhaust and self-locking device on alumina reservoir on the electrolyzer or the fluoride salt bin, belong to the electrolytic aluminum field.
Background technology
At present; In the electrolysis of aluminum prior art on the electrolytic bath gas barrier of aluminum oxide or fluoride salt bin mainly to be mounted in hopper inner, promptly vapor pipe and tremie pipe are in the same space and cause the self-locking highly can't to increase, so; During the hopper charging; When adopting air-driven chute or concentrated phase pipe to carry, because the self-locking insufficient height, band gas material will get in the electrolyzer through vapor pipe; The material that inorganization gets in the electrolyzer has brought many disadvantageous effects to electrolysis production, has seriously influenced each item technico-economical comparison of electrolyzer.To this drawback, taked following measure: the hopper loam cake is passed in the upper end of tremie pipe, and the upper end of vapor pipe still is positioned at hopper inside; As shown in Figure 1; Make vapor pipe and tremie pipe all keep certain self-locking discrepancy in elevation, but because hopper loam cake height is limited, so the discrepancy in elevation of vapor pipe and tremie pipe all can not be too big; Therefore lack partial material and also can get in the electrolyzer unavoidably, had a strong impact on the ordinary production of electrolyzer through vapor pipe.
Summary of the invention
The objective of the invention is to, a kind of electrolytic bath feed box exhausting and self-locking device are provided, this device is under the situation of the height that does not change the hopper loam cake, and the self-locking discrepancy in elevation between vapor pipe and the tremie pipe is bigger, and electrolysis production is stable during use.
Technical scheme of the present invention: comprise hopper 1; Be connected the hopper loam cake 2 of hopper 1 upper end; And vertically be arranged in the vapor pipe 3 and tremie pipe 4 in the hopper 1, and the upper end position of tremie pipe 4 is higher than hopper loam cake 2, and the upper end of described hopper loam cake 2 is connected with pipe box 5; Vapor pipe 3 passes hopper loam cake 2 and stretches into pipe box 5, and the upper end of tremie pipe 4 is positioned at outside the pipe box 5.
The upper end position of described vapor pipe 3 is higher than the lower end position of tremie pipe 4 far away, and both difference of altitude Δ h are 200 ~ 1000mm.Guarantee that its difference of altitude Δ h is in order to increase the self-locking height of material in the hopper, thereby guarantee that material can not get into vapor pipe and influence ordinary production.
Height h1<the 700mm of described pipe box 5 is spaces that increase is arranged for the height that makes vapor pipe.
The height h2 that described vapor pipe 3 stretches into pipe box 5 is 150~500mm, is in order to increase Δ h value, promptly to increase the self-locking height of material in the hopper.
Described pipe box 5 is connected with hopper loam cake 2 through welding, and described hopper loam cake 2 is connected with hopper 1 through bolt.
The present invention makes the height of vapor pipe increase greatly owing to adopted the mode of pipe box encapsulation vapor pipe, and material is difficult to get in the groove through vapor pipe with gas, thereby has stablized electrolysis production greatly.Promptly through appropriate design with original vapor pipe and tremie pipe material receiving box loam cake limitation in height and the less gas barrier of the self-locking discrepancy in elevation changed into and do not influence hopper loam cake height and can make the bigger novel exhaust device of the self-locking discrepancy in elevation between vapor pipe and the tremie pipe.And pipe box height, vapor pipe go deep into the reasonable setting of pipe box height, vapor pipe port and the direct difference of altitude of tremie pipe lower port, further guaranteed the self-locking height especially, stablized production.

Accompanying drawing 2 is a structural representation of the present invention.
Embodiment
Embodiments of the invention: this electrolytic bath feed box exhausting and self-locking device; Comprise hopper 1, be connected the hopper loam cake 2 of hopper 1 upper end, and vertically be arranged in vapor pipe 3 and tremie pipe 4 in the hopper 1; The upper end position of tremie pipe 4 is higher than hopper loam cake 2; The upper end of described hopper loam cake 2 is connected with pipe box 5, and vapor pipe 3 passes hopper loam cake 2 and stretches into pipe box 5, and the upper end of tremie pipe 4 is positioned at outside the pipe box 5.The height h1 of pipe box 5 is arranged in the 700mm, on the one hand on the whole can be not too high, and make the height of vapor pipe that the space of increase is arranged on the other hand again; The height h2 that vapor pipe 3 stretches into pipe box 5 is 150~500mm; Be in order to increase Δ h value, promptly increase the self-locking height of material in the hopper, the upper end position of vapor pipe 3 is higher than the upper end position of tremie pipe 4; Its difference of altitude Δ h has reached 200~1000mm, increases the self-locking height of material in the hopper greatly.Pipe box 5 is connected with hopper loam cake 2 through welding, and described hopper loam cake 2 is connected with hopper 1 through bolt.
During use; Alumina material or fluoride salt material get in the hopper 1 through tremie pipe 4; Make it highly increase in the pipe box 5 owing to welding on the upper end insertion hopper loam cake 2 of vapor pipe 3; Thereby tremie pipe 4 outlets and the self-locking discrepancy in elevation of vapor pipe 3 ingress are significantly strengthened, make sparkling material that the sufficient settling time arranged, cause waste and influence electrolysis production thereby can not get into vapor pipe 3 with gas.
Range of application: this invention design is to be installed on the electrolyzer alumina reservoir of differing capacities or the gas barrier on the fluoride salt bin; The installation dimension of its physical dimension and each several part can be carried out choose reasonable according to actual needs; Like the physical dimension and the installation dimension of hopper 1, hopper loam cake 2, and installation method, vapor pipe 3; Tremie pipe 4, the diameter of pipe box 5, length, wall thickness, installation site all can be adjusted according to different grooveds and configuration.
