Embodiment 1

[0043] Combine below Figure 4 Describe in detail the actual adjustment process and the effect after use of an alumina feeding system of the present invention:

[0044] Figure 4 After the alumina feeding system of the present invention is put into use, it is the data collected during a 2-hour random inspection from 10:00 am to 12:00 on a normal working day of the feeding production line, and the sampling time interval is once every 10 minutes;

[0045] Before starting the feeding control, set the standard lower limit of the feeding value to 4.5t, the standard upper limit of the feeding value to 5.5t, and the adjustment range to 0.5t on the program panel of the terminal 3, and then transmit the control data to the controller 2, and the controller communicates Feedback control mode controls the speed and direction of the geared motor 1-12 in the feeding system 1 in real time, so as to control the actual feeding value in real time, from Figure 4 It can be seen that the actual...

Abstract

The invention belongs to the field of electrolytic aluminium, and relates to an aluminium oxide pouring system used for stably controlling the pouring value of aluminium oxide. The aluminium oxide pouring system is composed of a pouring system 1 and a controller 2, wherein the pouring system 1 comprises an aluminium oxide 1-1, a manual gate valve 1-2, a pneumatic chute 1-3, a pouring impact plate flow meter 1-4, a main smoke pipe 1-5, a pouring port 1-6, a square-head bent pipe 1-7, a material buffer chamber 1-8, an inspection hole 1-9, a material hole 1-10, an exhaust pipe 1-11, a speed reduction motor 1-12, a linkage device 1-13, a local control box 1-14, a manual rotary wheel 1-15 and a gate valve 1-16; and the controller 2 is capable of controlling the rotational direction and the rotational speed of the speed reduction motor 1-12 to adjust the pouring value according to the parameters preset in a terminal 3 and the real-time data fed back by the pouring system 1, so that the pouring value is stabilized in a standard range. The aluminium oxide pouring system disclosed by the invention is capable of adjusting a time, lowering the labour amount and the human cost, improving the safety, and achieving the environmental protection requirement.

Description

technical field [0001] The invention belongs to the field of electrolytic aluminum, and in particular relates to an alumina feeding system for stably controlling alumina feeding. Background technique [0002] In the electrolytic aluminum industry, the raw materials of alumina need to be transported to the main smoke pipe through the feeding device. In the electrolytic aluminum production process, the fresh and fluorine-loaded alumina feeding system in the feed purification workshop is composed of: alumina storage bins, materials It consists of flapper valve, conveying chute and punching plate flowmeter. Calculate the feeding value according to the process requirements to ensure continuous and stable feeding into the smoke pipe, and realize the purification of the flue gas produced in the electrolysis workshop, so as to meet the environmental protection requirements of the enterprise. [0003] At present, there are the following problems in the commonly used feeding adjustme...
