Abstract
Disclosed is an exhaust apparatus for an aluminum electrolysis bath charging box, comprising a charging box, a feeding tube and an exhaust tube. The utility model is characterized in that firstly, the exhaust tube is wholly designed into a door-shaped or an inversed U-shaped tube; an inlet tube and an outlet tube of the exhaust tube are combined into a whole body through a connector; secondly, the air inlet tube of the exhaust tube is inserted into the discharging box but the nozzle of the outlet tube is positioned outside the discharging box; thirdly, the nozzle of the inlet tube of the exhaust tube is higher than the outlet of the feeding tube while the nozzle of the outlet tube is lower than the outlet of the feeding tube. The connector of the exhaust tube is arranged above the top cover of the discharging box in the utility model; due to the high position of the connector, even if the material surface filled into the bath may block the nozzle of the feeding tube and filled over the nozzle position of the exhaust tube, the material surface can never go into the electrolysis bath over the connector and through the exhaust tube; thus the problem of material leakage into the electrolysis bath is well solved.
Description
Technical field
The utility model belongs to the technical field of aluminium cell feed device, be specifically related to a kind of simple in structure, can solve material overflows or stop up gas exhaust duct from hopper aluminium cell feed device effectively.
Background technology
Aluminium cell generally all is by the hopper feed of chute to superstructure, and the discharge opening on the chute generally all is greater than or equal to the exhaust pipe mouth in the hopper.In the course of the work, can not stop usually owing to the chute feed because of single hopper is full of; When continuing feed, because the high pressure wind action in the chute, the material in the hopper that has been full of just is easy to overflow from vapor pipe, enters in the electrolyzer by vapor pipe, thereby the operation of electrolyzer is caused detrimentally affect.
Chinese patent ZL02222697.4 has reported a kind of " aluminium cell air-driven chute dumping device ", air-driven chute is placed the top of hopper, be connected with hopper by feed-pipe, it is characterized in that: the lower port of feed-pipe is lower than the upper port of vapor pipe, both are at a distance of 100～1000mm, however, still can not solve material effectively overflows and the final problem of stopping up vapor pipe from the upper port of vapor pipe (dust flue).Chinese patent ZL200420060178.7 " iris type aluminum oxide air-driven chute dumping device ", dividing plate one by one then is set separately with the top of hopper in hopper, make open type air-driven chute and vapor pipe place the mutual disconnected sealed vessel in dividing plate both sides respectively, its structure more complicated, it is also bigger to take up space.As for Chinese patent application case 2,005 10200150.8 " prevent alumina reservoir blanking from stopping up method and device ", at hopper anti-blowpipe with a plurality of nozzles can be set, then design is more complicated, it seems these all difficult enforcements.
The utility model content
The purpose of this utility model provides a kind of hopper gas barrier of simple in structure, reliable operation, to solve the above-mentioned drawback in the existing alumina reservoir gas barrier of aluminium cell.
Aluminium cell hopper gas barrier provided by the utility model comprises hopper, feed-pipe and vapor pipe, it is characterized in that:
(1) the vapor pipe global design becomes ∏ shape or inverted U-shaped, and its inlet pipe and outlet pipe are formed one by linker;
(2) inlet pipe of vapor pipe is inserted in the hopper, and its outlet pipe mouth of pipe is in beyond the hopper;
(3) the inlet pipe mouth of pipe of vapor pipe is higher than the feed-pipe outlet; Its outlet pipe mouth of pipe then is lower than the feed-pipe outlet.
Aluminium cell hopper gas barrier of the present utility model can have the slightly different design of two covers on the basis of above-mentioned design.Now be described below respectively:
First design is, vapor pipe is installed on the hopper top, and integral body is ∏ shape, and its linker is above the hopper top cover.Feed-pipe passes the linker and the inlet pipe part of vapor pipe from top to down, and and inlet pipe formation concentric structure.The suitable for reading of feed-pipe exceeds the linker top so that be connected with chute; Its end opening then is lower than the lower surface of vapor pipe inlet pipe, and becomes up big and down small doline.Be positioned at the exhaust outlet pipe of the linker the other end, its lower surface then is positioned at beyond the hopper, below the seal closure, air is discharged in the enclosed space of aluminium cell.When hopper fills when material, along with the rising meeting of charge level is at first sealed the lower end of feed-pipe, the continuation of hopper filled cause obstruction, at this moment, charge level also might continue to raise under the blast effect.But, when charge level reached vapor pipe inlet pipe lower surface, gas port was also blocked, because the vapor pipe inlet pipe is very high with the linker position between the outlet pipe, material will be crossed this position till the ass ascends the ladder, and this has just guaranteed that hopper no longer leaks material.
Second design be, vapor pipe is placed in the hopper top, and it is inverted U-shaped that integral body is, and its linker is on the hopper top cover.Feed-pipe then inserts separately in the hopper, and its lower surface is lower than the lower surface of vapor pipe inlet pipe.Stretch out downwards outside hopper the escape pipe lower surface of vapor pipe; And also can install big, a following young inlet pipe funnel suitable for reading below the inlet pipe additional, the funnel lower central has an osculum.When hopper fills material, along with raising, at first the lower surface of feed-pipe is sealed charge level, and material might rise to inlet pipe import funnel place under the blast effect at this moment, stops up the vapor pipe import.But because vapor pipe linker position is very high, this has just stoped the continuation of hopper to be filled effectively, guarantees that material does not take place to leak hopper.And final residue material in funnel also can fall into hopper again with the decline of charge level.
Description of drawings
Fig. 1 is the concrete structure synoptic diagram of first kind of design of the present utility model;
Fig. 2 is the concrete structure synoptic diagram of second kind of design of the present utility model.
In Fig. 1,2, the linker of 1 hopper, 2 feed-pipes, 3 vapor pipe inlet pipes, 4 exhaust outlet pipes, 5 vapor pipes, 6 inlet pipe funnels.
Embodiment
