[0002] Fluoride salts are an indispensable raw material in the electrolytic aluminum production process, playing a crucial role in controlling electrolyte temperature and maintaining the stability of electrolytic cell technology. The main methods for adding fluoride salts include manual addition, overhead crane transport, addition by specialized feeding vehicles, and addition via fixed containers. Currently, most electrolytic aluminum companies use fluoride salt feeding vehicles. However, because these vehicles are domestically produced and specially modified, their number in operation is limited. Furthermore, the design of this part by manufacturers is constrained by the actual operating environment, resulting in the problem of fluoride salt powder flying during the feeding process, which adversely affects the working environment. Utility Model Content

[0003] The purpose of this invention is to provide a dust collection device at the discharge port of a fluoride salt feeding vehicle to collect the fluoride salt powder material flying during the feeding process, so as to prevent fluoride salt dust from polluting the environment and ensure a clean and tidy working environment.

[0004] To achieve the above technical effects, the present invention provides a dust collection device for the discharge port of a fluoride salt feeding vehicle, comprising a feeder, the upper flange of which is fixedly connected to the lower end of the secondary conveying arm by fasteners, the lower flange of which is connected to the top of the feed box inlet, and a sealing end connected between the lower flange of which is connected to the feed box inlet. The device also includes a dust collection hood, comprising a top pipe, a conical pipe, and a bottom pipe. The inner diameter of the top of the conical pipe is smaller than the inner diameter of the bottom of the conical pipe. The top pipe is connected to the top of the conical pipe, and the bottom pipe is connected to the bottom of the conical pipe. The top pipe, conical pipe, and bottom pipe are coaxial, and the inner diameter of the top pipe is smaller than the inner diameter of the bottom pipe. The inner wall of the top pipe is fixedly connected to the outer shell of the feeder. The top pipe is located above the lower flange of the feeder, and the bottom end of the bottom pipe is located below the top surface of the feed box inlet. The connection surface between the lower flange of the feeder and the top of the feed box inlet is covered inside the dust collection hood.

[0005] Furthermore, it includes a dust collection box, the top surface of which is fixedly connected to the lower end of the secondary conveying arm. The dust collection box includes an air inlet and an air outlet. A negative pressure fan is connected to the air outlet of the dust collection box. A connector II is fixedly connected to the air inlet of the dust collection box. A through hole is provided on the tapered tube, and a connector I is fixedly connected to the through hole. A dust collection pipe is connected between connector I and connector II.

[0006] Furthermore, connector II is fixedly connected to the dust collection pipe via a snap fastener, and connector I is fixedly connected to the dust collection pipe via a snap fastener.

[0007] Furthermore, the dust collection box is provided with a dust discharge port at the bottom, and a blind plate is connected to the outside of the dust discharge port.

[0016] like Figures 1-2As shown, the dust collection device for the discharge port of a fluoride salt feeding vehicle of this utility model includes a feeder 1. The upper flange of the feeder 1 is fixedly connected to the lower end of the secondary conveying arm by fasteners. The lower flange of the feeder 1 is connected to the top of the material box inlet 2. A sealing end is connected between the lower flange of the feeder 1 and the material box inlet 2. The device also includes a dust collection hood 3, which includes a top pipe 301, a cone pipe 302, and a bottom pipe 303. The inner diameter of the top end of the cone pipe 302 is smaller than the inner diameter of the bottom end of the cone pipe 302. The top pipe 301 is connected to the top of the tapered pipe 302, and the bottom pipe 303 is connected to the bottom of the tapered pipe 302. The top pipe 301, tapered pipe 302 and bottom pipe 303 are coaxial. The inner diameter of the top pipe 301 is smaller than the inner diameter of the bottom pipe 303. The inner wall of the top pipe 301 is fixedly connected to the outer shell of the feeder 1. The top pipe 301 is located above the lower flange of the feeder 1. The bottom end of the bottom pipe 303 is located below the top surface of the feeder 1 inlet 2. The connection surface between the lower flange of the feeder 1 and the top of the feeder 1 inlet 2 is covered inside the dust collection hood 3.

[0017] Since the problem of fluoride salt powder flying during the feeding process occurs at the connection surface between the lower flange of the feeder 1 and the top of the feed box inlet 2, this utility model uses a dust collection hood 3 to cover the connection surface between the lower flange of the feeder 1 and the top of the feed box inlet 2, thereby preventing fluoride salt powder from flying during the feeding process.

[0018] However, simply setting up a dust collection hood 3 to disperse the powder cannot completely eliminate powder dispersion. With prolonged use, fluoride powder will still overflow from the bottom of the dust collection hood 3. Therefore, to further collect the fluoride powder, this invention also includes a dust collection box 5. The top surface of the dust collection box 5 is fixedly connected to the lower end of the secondary conveying arm. The dust collection box 5 includes an air inlet and an air outlet. A negative pressure fan 6 is connected to the air outlet of the dust collection box 5. A connector II 8 is fixedly connected to the air inlet of the dust collection box 5. A through hole is provided on the cone tube 302, and a connector I 304 is fixedly connected to the through hole. Connector I 304 is connected to... Dust collection pipe 4 is connected between connectors II and 8; connectors II and 8 are fixedly connected to dust collection pipe 4 by snap-fit ​​heads, and connector I 304 is also fixedly connected to dust collection pipe 4 by snap-fit ​​heads; the top pipe 301, cone pipe 302, and bottom pipe 303 are all connected by sealed welding, and the top pipe 301 is connected to the outer shell of the feeder 1 by sealed welding; connector I 304 is connected to cone pipe 302 by sealed welding, and the sealed welding ensures airtightness. Connector I 304 is located in the middle of the height direction of cone pipe 302; the dust collection pipe 4 is a steel wire hose, and the inner diameter of dust collection pipe 4 is ≥100mm.

[0019] The operation of the negative pressure fan 6 creates a negative pressure inside the dust collection box 5, thereby absorbing the fluoride salt powder in the dust collection hood 3 into the dust collection box 5 through the dust collection pipe 4, thus collecting the fluoride salt powder and fundamentally solving the problem of fluoride salt powder flying around.

[0020] The connecting clips of connector II8 and dust collection pipe 4, and connector I304 and dust collection pipe 4, can be made with existing sealing connectors, such as straight-insertion pipe connectors, etc., which will not be listed here.

[0021] The negative pressure fan 6 is powered by 12V or 24V. The power supply of the negative pressure fan 6 can be directly connected to the battery of the fluoride salt feeding vehicle.

[0022] A dust filter screen should be installed at the air outlet of dust collection box 5, and the negative pressure fan 6 should be equipped with an exhaust filter to prevent dust from being generated at the exhaust outlet of the negative pressure fan 6. It is recommended that dust collection box 5 be fastened to the lower end of the secondary conveyor arm for easy disassembly.

[0023] The dust collection box 5 has a dust discharge port at the bottom, and a blind flange 7 is connected to the outside of the dust discharge port. The dust discharge port facilitates the removal of dust from the dust collection box 5.

[0024] The vertical distance between the bottom end of the bottom tube 303 and the top surface of the inlet 2 is a, where a ≥ 80 mm. The vertical distance between the bottom end of the bottom tube 303 and the top surface of the inlet 2 is ≥ 80 mm, thus ensuring that the fluoride salt powder will not overflow from the bottom end of the bottom tube 303.

[0025] This invention uses a dust collection hood 3 to confine the flying fluoride salt powder within the hood 3, and then uses a negative pressure fan 6 and a dust collection pipe 4 to collect the flying fluoride salt powder into a dust collection box 5. This fundamentally solves the problem of flying fluoride salt powder during the feeding process, avoids fluoride salt dust pollution of the environment, and ensures a clean and tidy working environment. The dust collection pipe 4 uses a steel wire hose, which has excellent durability and sealing performance and low maintenance costs. The dust discharge port and blind flange 7 of the dust collection box 5 facilitate the regular centralized collection of powder, making it convenient for the centralized disposal of collected fluoride salt and avoiding resource waste. The negative pressure fan 6 is powered by the battery of the fluoride salt feeding vehicle, requiring only modification of the original power supply line without the need for additional energy systems.
