[0002] Fluoride salts are generally added during the electrolysis of aluminum. Fluoride salts play a role in lowering the melting point, improving conductivity and inhibiting solubility during the electrolysis of aluminum, which helps to achieve efficient aluminum electrolysis production. In order to add fluoride salts, they are often added to the electrolytic cell through a feed pipe. The feed pipe is located above the electrolytic cell and is aligned with the feed port of the cell cover. Dust diffusion occurs during the feed process, and some of the dust may fall on the cell cover at the top of the electrolytic cell.

[0024] See also Figure 1 to Figure 2 , the embodiments of the present application provide an electrolytic cell feeding device and an electrolytic cell equipment.
[0025] The electrolytic cell equipment includes an electrolytic cell 200, an overhead crane 300 and an electrolytic cell unloading device.
[0026] The electrolytic cell 200 may be an electrolytic cell 200 for electrolyzing aluminum, including a cell structure, a cell cover, an electrolyte, a conductive system, an anode and a cathode, and other components or modules capable of realizing the electrolysis process.
[0027] The cell structure can be made of high temperature resistant and corrosion resistant materials, such as carbon materials or ceramic materials. The cell structure contains electrolyte, anode and cathode, etc. The electrolyte is a mixture used to conduct current and dissolve aluminum oxide. The anode is made of carbon material, such as coke or carbon block. The anode is oxidized during the electrolysis process and releases oxygen. The cathode is made of aluminum metal, which is the target product in the electrolysis process. Aluminum metal is precipitated on the cathode and is collected and extracted. The conductive system may include a current introduction device, a current distribution device and a current collection device, etc., which are used to provide current to the electrolytic cell 200 so that the electrolysis reaction occurs. The cell cover is used to cover the cell structure so that the electrolytic cell 200 has good sealing and durability to ensure the stability and continuity of the electrolysis process. In addition, a gas collection device may be provided on the cell cover to collect released gases, such as oxygen and hydrogen fluoride.
[0028] The electrolytic cell unloading device can be used for unloading fluoride salt, and includes a silo 410 , a unloading pipe 420 , a control valve (not shown), an air compressor 110 , a connecting air pipe and an air blowing member 130 , which are respectively installed on the overhead travelling crane 300 .
[0029] The feed pipe 420 is connected to the silo 410, wherein the control valve is located between the feed pipe 420 and the silo 410 and is used to control the feeding state of the feed pipe 420, wherein the control valve may be a gate valve. The discharge port of the feed pipe 420 is located at the upper part of the electrolytic cell 200. A feed port is also provided on the tank cover to facilitate the entry of materials into the electrolytic cell 200. When feeding, the control valve is controlled to open, and the materials in the silo 410 can enter the electrolytic cell 200 through the feed pipe 420. The feed pipe 420 and the silo 410 may be made of metal, such as but not limited to titanium alloy, stainless steel, and nickel alloy.
[0030] The air compressor 110 is mounted on the overhead crane 300. The air compressor 110 can be a piston compressor (reciprocating compressor), a screw compressor, a turbo compressor, a permeation compressor, an axial flow compressor, etc. The piston compressor achieves gas compression by the up and down reciprocating motion of the piston in the cylinder. Piston compressors are divided into single-stage and multi-stage types, and multi-stage piston compressors can achieve a higher compression ratio. The screw compressor consists of two intermeshing screws (a main screw and a slave screw), and the air is gradually compressed by their rotational motion. The turbo compressor uses a high-speed rotating impeller (also called a centrifugal wheel) to generate centrifugal force to push the air to the compression chamber wall to achieve gas compression. The axial flow compressor uses the rotation of the blades and the action of the guide vane to push the gas from the axial direction to the radial direction, and achieves gas compression through the compression action of the blades. Here, the present application does not limit the specific form of the air compressor 110.
[0031] The connecting pipe 120 is used to connect the air compressor 110 and the blowing piece 130. Of course, there is no limitation on the specific preparation material of the connecting pipe 120. Designers can make reasonable choices according to actual needs. The connecting pipe 120 can be made of plastic materials, such as but not limited to polyvinyl chloride (PVC), polypropylene (PP) and polypropylene polyurethane (PPR); the connecting pipe 120 can also be made of metal materials, such as but not limited to copper, stainless steel and aluminum.
[0032] See also Figure 1 The blowing member 130 is fixed to the outer wall of the feeding pipe 420, and the air inlet of the blowing member 130 is connected to the air outlet of the air compressor 110. The blowing member 130 is provided with a plurality of blowing ports, which blow air outward under the drive of the air compressor 110 and purge the upper part of the electrolytic cell 200. Of course, the specific preparation material of the blowing member 130 is not limited here, and the designer can make a reasonable choice according to actual needs. The blowing member 130 can be a plastic material, such as but not limited to polyvinyl chloride (PVC), polypropylene (PP) and polypropylene polyurethane (PPR); the connecting pipe 120 can also be a metal material, such as but not limited to copper, stainless steel and aluminum.
[0033] The blowing piece 130 and the connecting pipe 120 can be an integrally formed component, which can be integrally formed by injection molding of plastic material, or can be hot-pressed or stamped by metal material; they can also be separate components connected by bolt connection or welding, etc., which is not limited in this application.
[0034] In some structural forms, see Figure 1 and Figure 2The blowing member 130 includes an air intake pipe 131, a main pipe 132 and a plurality of nozzles 133, and the air intake pipe 131 is connected to the connecting pipe 120. The plurality of nozzles 133 are arranged at intervals in the length direction of the electrolytic cell 200, so that the area of the upper part of the electrolytic cell 200 swept by the blowing member 130 can be increased, thereby improving the dust removal effect.
[0035] Of course, the plurality of nozzles 133 are spaced apart in the width direction of the electrolytic tank 200, or spaced apart in both the length direction and the width direction of the electrolytic tank 200. Figure 1 As exemplarily shown in FIG, five blowing pipes are arranged at intervals in the length direction. Figure 2 As shown in the example, the five blowing pipes are arranged at intervals in the length direction and the width direction. Here, the number and arrangement of the nozzles 133 are not limited in this application.
[0036] In order to facilitate the installation of the blowing piece 130 and the connecting pipe 120 on the outer wall of the feeding pipe 420, the embodiment of the present application further includes a mounting device 140, which fixes the connecting pipe 120 and the blowing piece 130 on the outer side wall of the feeding pipe 420. In some structural forms, the mounting device 140 can be a mounting rod, and there are multiple mounting rods, which are arranged at intervals in the height direction, wherein one end of the mounting rod is welded to the outer wall of the feeding pipe 420, and the other end can be welded and fixed to the connecting pipe 120 or the blowing piece 130, so that the blowing piece 130 and the connecting pipe 120 can be installed on the outer wall of the feeding pipe 420. This installation form is simple and has high stability, and in this installation form, the connecting pipe 120 or the blowing piece 130 are both made of metal.
[0037] In some other embodiments, the installation device 140 may also include a tightening device and a locking device. One end of the tightening device is provided with a first tightening portion and a second tightening portion which are sleeved on the connecting pipe 120. The first tightening portion and the second tightening portion are locked by the locking device, so that the tightening device and the connecting pipe 120 can be relatively fixed, and then the other end of the tightening device is fixed to the outer wall of the discharge pipe 420, for example but not limited to clamping, screwing, welding and the like. Here, the present application does not limit the specific form of the installation device 140.
[0038] The feed pipe 420 includes a vertical section 421 and an inclined section 422 connected to each other. The discharge port of the feed pipe 420 is arranged at the bottom of the inclined section 422. The inclined section 422 is inclined in a direction away from the blowing member 130, thereby increasing the distance between the discharge port and the blowing port and improving the independence of the two when working.
[0039] To facilitate the control of the purging and dust removal work of the embodiment of the present application, the embodiment of the present application also includes a control module, which is electrically connected to the air compressor 110 and is used to control the working state of the air compressor 110. The control module can be a manual switch, a PLC (programmable logic controller) or other similar automatic control equipment. The control module is electrically connected to the air compressor 110, and controls the purging work of the blowing member 130 by controlling the working state of the air compressor 110. The control module can use a solenoid valve 150 as an actuator. When cleaning is required, the control module controls the solenoid valve 150 to open, the air compressor 110 is connected to the power supply and supplies air to the blowing member 130, and the blowing member 130 starts to purge the upper part of the electrolytic cell 200; when the purging work is not required, the control module controls the solenoid valve 150 to close, the air compressor 110 stops working and cuts off the airflow, and the blowing member 130 stops purging.
[0040] In some structural forms, the control module can also be electrically connected to the above-mentioned control valve. In this way, the present application can remotely control the unloading operation and purging operation of the unloading device through the control module, thereby ensuring the safety and health of the operator.
[0041] In summary, the unloading device of the embodiment of the present application installs the connecting pipe 120 and the blowing member 130 on the outer wall of the unloading pipe 420, installs the air compressor 110 on the overhead crane 300 and supplies air to the blowing member 130 through the connecting pipe 120, and can clean the electrolytic cell 200 through the blowing member 130 after unloading is completed or when cleaning is required. Compared with the form of manually cleaning the upper part of the electrolytic cell 200 with a broom or a scraper, the unloading device of the present application can not only meet the unloading operation, but also clean the electrolytic cell 200, and effectively improve the cleaning efficiency.
