Abstract
The utility model discloses a continuous feeding device for an aluminum electrolytic bath, which comprises an aluminum oxide case (2). A ball valve (3) is connected to the lower portion of the aluminum oxide case (2), a vibrating feeder (1) is disposed on the lower side of the ball valve (3), a discharge pipe (4) is arranged below a discharge end of the vibrating feeder (1), and the vibrating feeder (1) is a miniature electromagnetic vibrating feeder. The continuous feeding device can realize continuous feeding for the aluminum electrolytic bath conveniently and simply, the vibrating feeder can be maintained or replaced only by closing the ball valve, and materials in the case can not enter the electrolytic bath.
Description
Technical field
The utility model relates to the feeding device on a kind of aluminium cell.
Background technology
What Aluminium Electrolysis adopted is fused salt electrolysis technology, makes equipment with aluminium cell, and aluminum oxide is made the electrolysis raw material, generates metallic aluminium with sodium aluminum fluoride electrolyte dissolution aluminum oxide through electrochemical reaction.The aluminum oxide that is dissolved in the ionogen constantly consumes in electrolytic process, several alumina reservoirs and several alumina feeding device is all arranged to replenish on aluminium cell.Present alumina feeding device all is the volumetric feed device by air cylinder driven.This volumetric feed device has a fixed room, the opening for feed of an interlock and discharge port, and one of cylinder action comes and goes, and feeder is finished and is once filled material and discharge, and the alumina material with hopper quantitatively is added in the electrolyzer.The maximum volumetric feed device of domestic use is 1.8 liters of cartridge type volumetric feed devices, and other also had 4 liters, the volumetric feed device of 1.2 liters of grades.With varying in size of electrolyzer, every electrolyzer has 4,5 or 6 volumetric feed devices.
Because alumina concentration changes electrolytical liquidus temperature, electric conductivity all there is considerable influence, and then influence electrolytic temperature and power consumption, therefore alumina concentration is a very important controlled variable in the Aluminium Electrolysis process, alumina concentration control is proper, just can obtain to produce stably and good productive capacity.In order to enhance productivity, reduce power consumption, will reduce the fluctuation of alumina concentration in the electrolysis production as far as possible, " sparing no effort to the worker, few blanking " all pursued in feeding in raw material of electrolyzer.Processing just is meant that crust-breaking chips opens crust, and feeder adds a cover action of alumina material then.
Guizhou Aluminum Factory 160kA prebaked cell when nineteen eighty-two goes into operation has 6 pneumatic feeders, and each reinforced at every turn 15kg moves once simultaneously every one hour 6 feeder, each 90kg that feeds in raw material that amounts to.Through improving for many years, use 4 1.8 liters cartridge type volumetric feed devices now, once every action in ~ 13 minutes.Optimally spare no effort to the worker, few blanking is exactly a continuous charging.
General cartridge type volumetric feed device all is mounted in the bottom in the alumina reservoir now, and cartridge type volumetric feed device is embedded in the middle of the alumina material, and blocks the outlet of hopper.Aluminum oxide enters electrolyzer by feeder and electrolyzer intermediary elephant trunk, temperature height herein, and the people advances not go.Need pull down when maintenance when feeder is out of order, the material stock in the hopper inevitably enters into electrolyzer.It is very deleterious that a large amount of aluminum oxide enter electrolyzer.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of aluminum electrolyzing cell used continuous feeding is provided, deficiency such as is easy to enter in the electrolyzer with the material stock in reinforced discontinuous, the hopper that overcomes that prior art exists.
The utility model is taked following technical scheme: it comprises alumina reservoir, connects ball valve in the bottom of alumina reservoir, and the ball valve below is provided with oscillating feeder, and the discharge end below of oscillating feeder is provided with tremie pipe.
Oscillating feeder adopts the micro electromagnetic oscillating feeder.
The micro electromagnetic oscillating feeder is a kind of series product, has been used for industries such as light industry, chemical industry, but also has been not used on the aluminium cell.The utility model is that the micro electromagnetic oscillating feeder is used on the electrolyzer as the alumina feeding device.
Alumina powder in the alumina reservoir flows to by ball valve on the hopper of oscillating feeder, by the flow of oscillating feeder by control, is transported to the blanking steel pipe, and falls the charging opening of electrolyzer, enters fused electrolyte, finishes reinforced.Regulate the placement angle of oscillating feeder, can regulate the material amount.
The utility model can make things convenient for the continuous charging of succinct realization aluminium cell.As long as the utility model is closed ball valve, just can keep in repair or change oscillating feeder, the material of hopper can not enter electrolyzer.

Fig. 1 is a synoptic diagram of the present utility model.
Embodiment
Embodiment of the present utility model: it comprises alumina reservoir 2, connects ball valve 3 in the bottom of alumina reservoir 2, and ball valve 3 belows are provided with oscillating feeder 1, and the discharge end below of oscillating feeder 1 is provided with tremie pipe 4.
Oscillating feeder 1 adopts the micro electromagnetic oscillating feeder.
Electrolyzer can be equipped some each and every one alumina feeding devices, generally is no more than six.The alumina feeding device is placed on the upper mechanism of electrolyzer.
Claims (2)
1. aluminum electrolyzing cell used continuous feeding, it comprises alumina reservoir (2), it is characterized in that: the bottom at alumina reservoir (2) connects ball valve (3), and ball valve (3) below is provided with oscillating feeder (1), and the discharge end below of oscillating feeder (1) is provided with tremie pipe (4).
2. aluminum electrolyzing cell used continuous feeding according to claim 1 is characterized in that: oscillating feeder (1) is the micro electromagnetic oscillating feeder.
