Abstract
The utility model relates to a gas removing device of an aluminum reduction cell, in particular to a device which is used for removing the discharged gas in the reduction cell through a fiery eye arranged at the median suture of an aluminum electrolytic anode. The gas removing device is characterized in that the structure of the device comprises a gas-collecting hood and a material inlet hopper, wherein, the gas-collecting hood is of a metal box body which is reversely buckled at the upper part of the aluminum reduction cell fiery eye, and the lower end of the metal box body is of an opening, the side wall of the gas-collecting hood box body is provided with a gas removing hole, and a top cover is opened with a material inlet hole, the material inlet hopper is of a funnel shape and is positioned on the upper side of the gas-collecting hood, and an opening at the lower end of the hopper is fixedly connected with the material inlet hole of the top cover on the gas-collecting hood. The fiery eye and the surrounding gas can be separated by the gas-collecting hood of the utility model, positive pressure is formed in the gas-collecting hood, the gas mixing is prevented, an iron pipe used for gas removing can extend into the gas-collecting hood from the gas removing hole, and the gas can smoothly enter into the gas removing pipe under the action of the positive pressure, thereby enabling the obtained gas sample to have authenticity, stability and representativeness, and providing the authentic gas sample for the detection of the instantaneous current efficiency.
Description
Technical field
This practicality relates to a kind of aluminium cell collector, is used for the device that aluminium electrolysis anode centre joint pinkeye is taken out emission gases in the electrolytic tank.
Background technology
The instantaneous current efficiency of aluminium cell is an important parameters of reaction electrolytic tank operation conditions, and Aluminium Electrolysis is had important directive significance.The instantaneous current efficiency of aluminium cell can be measured according to the gas componant that discharges in the electrolytic tank in the electrolytic process, gets the whether representative instantaneous current efficiency precision of analysis that directly determined of gas.In analysis in the past, all adopt an iron pipe directly to reach the pinkeye mouth and get gas.The gas method of getting like this has following shortcoming: the first, because the pinkeye mouth opens wide easy entrained air in the gas of getting; The second, need the people when getting gas and grasp iron pipe, grasp the position of getting gas, so not only labor capacity is big, and gas representativeness and the poor stability got, and the iron pipe position changes slightly, will cause the variation of gas componant; The 3rd, the iron pipe position is difficult to fix, if far away from the pinkeye mouth, the carbon monoxide that discharges in the electrolytic tank generation carbon dioxide that burnt, composition changes, if too near from the pinkeye mouth, iron pipe is stopped up by electrolyte easily; The 4th, directly iron pipe is reached the pinkeye mouth, hinder normal charging, and iron pipe can be blocked during charging.
Summary of the invention
The purpose of this utility model is the defective that exists at above-mentioned prior art, provides a kind of and can make gaseous sample authenticity, stability of getting and the aluminium cell collector that does not hinder normal charging.
The objective of the invention is to be achieved through the following technical solutions.
A kind of aluminium cell collector is characterized in that the structure composition of this device comprises:
Gas skirt-this gas skirt be one tip upside down on aluminium cell pinkeye top, the lower end is uncovered metal box-like body; On the sidewall of gas skirt box-like body, have and get pore, have charging hole on the upper top cover;
Feed hopper-this hopper is a funnel-form, is positioned at the gas skirt top, and its hopper lower ending opening and gas skirt upper top cover charging hole are affixed.
The aluminium cell collector of wood utility model, lower part is a gas skirt, it can be put into above the pinkeye of aluminium cell, pinkeye and ambient air are separated, in gas skirt, form malleation, stoped sneaking into of air, prevent that the carbon monoxide that discharges in the electrolytic tank is oxidized, and can make the gas mixing in getting gas hood that discharges in the electrolytic tank, get stable, representative gas; Getting gas hood top is a funnelform feed arrangement, does not hinder the normal charging of aluminium oxide, and iron pipe can be blocked when preventing charging; Getting on the gas skirt wall of gas hood has to get a pore, can extend into the iron pipe of getting gas to get the gas hood the inside from getting pore, and gas is got the tracheae the inside because the effect of malleation can enter into smoothly.
Description of drawings
Fig. 1 is the front view of utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
A kind of aluminium cell collector, the structure of this device is formed and is comprised: gas skirt-this gas skirt be one tip upside down on aluminium cell pinkeye top, the lower end is uncovered metal box-like body 1; On the sidewall of gas skirt box-like body, have and get pore 2, have charging hole 3 on the upper top cover; This hopper of feed hopper 4-is a funnel-form, is positioned at the gas skirt top, and its hopper lower ending opening and gas skirt upper top cover charging hole are affixed.
Hopper of the present utility model can be coniform, and gas skirt can be rectangular parallelepiped, has one to get pore on the gas skirt, can extend into the iron pipe of getting gas to get gas hood the inside and get gas from getting pore, gets the size of pore and is a bit larger tham the external diameter of getting tracheae.Hopper and gas skirt are welded by aluminium sheet, iron plate or corrosion resistant plate.The height of collector should be lower than the height between electrolytic tank feed opening and the pinkeye slightly, generally between 200～300mm.The height of hopper and gas skirt respectively accounts for whole getting about half of gas hood height.The size of gas skirt part opening according to the size of pinkeye and around the distribution situation decision of anode, make it can cover pinkeye and do not stay obvious gaps on every side.
When getting gas, insert getting in the pore of gas skirt, utilize the malleation of its gas can finish the gas process of getting smoothly getting tracheae.
