Description

Technical Field

[0001] This invention relates to the field of feeder technology, and in particular to a device for testing the function of an electrolytic aluminum feeder. Background Technology

[0002] The alumina and fluoride salt feeder is a core component at the top of the electrolytic cell, responsible for feeding the necessary raw materials (alumina and fluoride salts). The accuracy of the feed rate directly affects important parameters such as the stability, thermal balance, current efficiency, and molecular ratio of the electrolytic cell. However, currently, repaired feeders can only be tested under no-load conditions, making it impossible to measure their performance. If directly installed on the electrolytic cell, inaccurate feed rates or leaks from poorly repaired feeders will necessitate secondary replacements. This not only affects the electrolytic cell's process parameters but also increases labor intensity and reduces work efficiency.

[0003] In summary, providing a device for testing the function of an electrolytic aluminum feeder is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a device for testing the function of an electrolytic aluminum feeder, so as to solve the problems existing in the prior art. It has the function of simulating a material box in an electrolytic cell and can realize the function testing of the feeder.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides a device for testing the function of an electrolytic aluminum feeder, comprising a material box, a feeding valve, a base bracket, and a weighing scale. The electrolytic aluminum feeder to be tested is installed on the top of the material box. The feeding valve is used to control the feeding of the electrolytic aluminum feeder. The base bracket is located at the bottom of the material box to support the material box. The weighing scale is located at the bottom outlet of the material box to weigh the feeding amount of the electrolytic aluminum feeder in one feeding.

[0007] Preferably, the electrolytic aluminum feeder is fixed to the top of the material box by anchor bolts.

[0008] Preferably, the discharge valve is installed at the feed inlet of the material box.

[0009] Preferably, the feeding valve is connected to the electrolytic aluminum feeder via an air duct, and the air inlet of the feeding valve is connected to a compressed air duct.

[0010] Preferably, the base support includes two portal-shaped legs and two crossbeams connected between the two portal-shaped legs, and the bottom of the material box is welded to the two crossbeams.

[0011] Preferably, the discharge port is located at the center of the bottom of the material box, and the weighing scale is located directly below the discharge port.

[0012] The present invention achieves the following technical effects compared to the prior art:

[0013] The device for testing the function of the electrolytic aluminum feeder in this invention allows for feeding tests after feeder repair. By comparing the feeding amount with the standard feeding amount, the effectiveness of the feeder repair can be determined. If the feeding amount deviates significantly from the standard amount or if leakage occurs, the feeder is removed and repaired again, preventing a substandard feeder from affecting the electrolytic process parameters when installed on the electrolytic cell. Testing the feeder's repair status before installation avoids secondary replacements and improves maintenance efficiency. Attached Figure Description

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The device for testing the function of the electrolytic aluminum feeder in this embodiment, such as... Figure 1As shown, it includes a material box 4, a feeding valve 3, a base bracket 5, and a weighing scale 6. The electrolytic aluminum feeder 1 to be tested is installed on the top of the material box 4. The feeding valve 3 is used to control the feeding of the electrolytic aluminum feeder 1. The base bracket 5 is set at the bottom of the material box 4 to support the material box 4. The weighing scale 6 is set at the bottom outlet of the material box 4 to weigh the feeding amount of the electrolytic aluminum feeder 1 in one feeding.

[0021] In this specific embodiment, the electrolytic aluminum feeder 1 is fixed to the top of the material box 4 by the anchor bolts 7.

[0022] In this specific embodiment, the feeding valve 3 is installed at the inlet of the material box 4. The feeding valve 3 is connected to the electrolytic aluminum feeder 1 through the air pipe 2. The air inlet of the feeding valve 3 is connected to the compressed air pipe 2. Compressed air is used as a power source to realize the feeding control of the feeding valve 3.

[0023] In this specific embodiment, the base support 5 includes two portal-shaped legs and two crossbeams connected between the two portal-shaped legs, and the bottom of the material box 4 is welded to the two crossbeams.

[0024] In this specific embodiment, a discharge port is provided at the bottom center of the material box 4, and the weighing scale 6 is located directly below the discharge port. The electrolytic aluminum feeder 1 is transported to the alumina or fluoride salt in the material box 4 through the feeding valve 3, and falls onto the weighing scale 6 through the discharge port for weighing.

[0025] The working process of the device for testing the function of the electrolytic aluminum feeder in this invention is as follows:

[0026] The action of discharge valve 3 enables the constant-volume discharger to complete one discharge cycle. Alumina or fluoride salts in the material bin 4 fall into the weighing scale, thus measuring the discharge quantity for one cycle. By comparing this quantity with the standard discharge quantity, the effectiveness of the discharger maintenance can be determined. If the discharge quantity deviates significantly from the standard quantity or if leakage occurs, the discharger should be removed and repaired again to prevent a substandard discharger from affecting the electrolytic process parameters when installed on the electrolytic cell.
