Description

Technical Field

[0001] This utility model relates to the technical field of flue gas purification equipment, specifically to a dust collection and purification equipment for electrolytic aluminum flue gas. Background Technology

[0002] Utility model patent CN213995391U discloses a flue gas purification device for the electrolytic aluminum industry, including a purification box. A motor is installed on the lower end of the purification box, and the output end of the motor passes through the bottom of the purification box and extends into the interior of the purification box. Multiple evenly distributed stirring rods are fixedly connected to the outer wall of the rotating shaft. Stirring blades are fixedly connected to the ends of the stirring rods away from the rotating shaft. A spray box is fixedly connected to the upper end of the purification box. The motor drives the rotating shaft to rotate, and the rotating shaft drives the multiple stirring rods and stirring blades to rotate, stirring the sodium carbonate solution inside the purification box, thereby making the fluoride in the flue gas fully mixed with the sodium carbonate solution, greatly improving the reaction efficiency and effect.

[0003] In the process of developing this application, the following problems were found with this technology: the flue gas was not initially filtered to remove dust, which caused the dust to enter the solution and affect the reaction of fluoride. At the same time, the filtration mechanism is prone to clogging during long-term use, resulting in poor purification effect of fluoride in the flue gas in the later stage.

[0004] To address these shortcomings, a dust collection and purification device for electrolytic aluminum flue gas is proposed, which is an upgrade and modification of the existing device. Utility Model Content

[0005] The purpose of this utility model is to provide an electrolytic aluminum flue gas purification and dust collection device to solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An electrolytic aluminum flue gas purification and dust collection device includes a flue gas filter box. An air inlet pipe is fixedly installed on the upper left side of the flue gas filter box. A fan is fixedly installed at the end of the air inlet pipe away from the flue gas filter box. A ventilation duct is fixedly installed at the end of the fan away from the air inlet pipe. A conical filter barrel is fixedly installed at the bottom of the flue gas filter box.

A flue gas purification box is fixedly installed at one end of the air outlet pipe. An exhaust pipe is fixedly installed on the upper outer side of the flue gas purification box. A stirring mechanism is provided inside the flue gas purification box.

[0008] Furthermore, a support frame is fixedly installed at one end of the flue gas filter box near the fan, and the surface of the support frame is fixedly installed to the bottom of the fan.

[0009] Furthermore, a collection box is slidably connected to the bottom of the flue gas filter box, and a handle is fixedly installed at the end of the collection box away from the flue gas filter box.

[0010] Furthermore, a liquid inlet is fixedly installed at the upper end of the flue gas purification box, and a liquid drain valve is fixedly installed on the lower side of the outer end of the flue gas purification box.

[0011] Furthermore, the stirring mechanism includes a second motor. The second motor is fixedly installed at the middle of the upper end of the flue gas purification box. A rotating rod is fixedly installed on the output shaft of the second motor. The end of the rotating rod near the second motor is rotatably connected to the inner wall of the flue gas purification box through a bearing. A hollow rotating shaft is fixedly installed at the lower end of the rotating rod. A hollow stirring rod is fixedly installed at the outer end of the hollow rotating shaft. An air outlet is opened at the outer end of the hollow stirring rod. The end of the hollow rotating shaft away from the rotating rod is rotatably connected to the inner wall of the flue gas purification box through a bearing. One end of the air outlet pipe passes through the flue gas purification box and extends into the interior of the hollow rotating shaft.

[0012] Furthermore, a one-way valve is fixedly installed on the inner wall side of the hollow rotating shaft near the outlet pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a conical filter barrel to filter dust from flue gas. By starting a motor, the transmission rod rotates, causing a cleaning plate to clean the surface of the conical filter barrel and remove the filtered dust. The cleaned dust is then transported to a collection box through a perforation for easy dust collection and to improve the filtration life of the conical filter barrel.

[0015] This invention delivers filtered air to a hollow rotating shaft via an air outlet pipe, and then through an air outlet via a hollow stirring rod to deliver the air into the purification chamber, where the fluorides in the air are purified. By starting a motor, the rotating rod is rotated, which in turn causes the hollow rotating shaft to rotate the hollow stirring rod, allowing the purification liquid and fluorides to react fully and improving the purification effect of the fluorides.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a support frame 173 is fixedly installed at one end of the flue gas filter box 1 near the fan 171. The surface of the support frame 173 is fixedly installed to the bottom of the fan 171. A collection box 11 is slidably connected to the bottom of the flue gas filter box 1.
