Description

Technical Field

[0001] This utility model relates to the technical field of metal smelting equipment, specifically to an environmentally friendly recycled aluminum alloy smelting device. Background Technology

[0002] The smelting process of recycled aluminum alloys generates a large amount of dusty waste gas containing sulfur oxides, which can pollute the environment if directly emitted. To protect the environment and reduce pollution, dust collectors such as bag filters, wet scrubbers, and plate filters are typically used to remove dust from the waste gas, followed by a spray tower to adsorb the sulfur oxides. Plate filters are favored due to their washability.

[0003] The high dust and impurity content in the exhaust gas causes dust to accumulate rapidly in the dust removal equipment. For example, dust accumulates at the bottom of a plate filter, clogging the mesh of the filter plate and affecting the filtration efficiency of the dust removal device, requiring frequent cleaning. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly recycled aluminum alloy smelting device that can clean the dust accumulated in the plate filter of the device, so as to avoid the dust clogging the filter plate and affecting the filtration efficiency of the exhaust gas.

[0005] To achieve the above objectives, an environmentally friendly recycled aluminum alloy smelting device is provided, comprising a spray tower and a smelting furnace. The smelting furnace has a flue gas outlet at its upper center, and a first exhaust pipe is fixedly connected to the flue gas outlet, communicating with the smelting furnace. A booster pump is fixedly connected to the other end of the first exhaust pipe, and the first exhaust pipe is connected to the input end of the booster pump. A second exhaust pipe is fixedly connected to the output end of the booster pump. A dust removal mechanism is fixedly connected to the other end of the second exhaust pipe, away from the booster pump, and the interior of the dust removal mechanism is connected to the second exhaust pipe. The spray tower has an air inlet, which is fixedly connected to the middle of one end of the dust removal mechanism, and the air inlet of the spray tower is away from the second exhaust pipe. This device can clean the dust accumulated in the plate filter, preventing dust from clogging the filter plates and affecting the filtration efficiency of the exhaust gas.

[0006] According to the aforementioned environmentally friendly recycled aluminum alloy smelting device, the dust removal mechanism comprises an ash storage box, a motor, an equipment shell, a filter plate, a dust removal roller, and a guide rail. The second air outlet pipe is fixedly connected to the middle of one end of the equipment shell, and the equipment shell has an opening communicating with the second air outlet pipe. The end of the equipment shell furthest from the second air outlet pipe is fixedly connected to the air inlet of a spray tower. The ash storage box has a convex structure and is fixedly connected to the middle of the lower end of the equipment shell. The upper end of the ash storage box has an opening that penetrates and communicates with the equipment shell. The inner wall of the equipment shell... Several guide rails are fixedly connected at equal intervals at the top. Several filter plates are slidably connected at equal intervals on the inner wall of the equipment shell, with the top of the filter plates extending into the guide rails and slidably connected to the inner wall of the guide rails. The cleaning roller is located in the opening of the ash storage box, and the outer end of the cleaning roller is slidably connected to the side wall of the opening. Both ends of the cleaning roller pass through the equipment shell and are rotatably connected to the equipment shell. The motor is fixedly connected to the outer ends of the ash storage box and the equipment shell, and the output end of the motor is fixedly connected to the middle of the cleaning roller. Several cleaning grooves are equidistantly provided on the surface of the cleaning roller, and the cleaning grooves are located on the side of the filter plate facing the second air outlet pipe. The motor drives the cleaning roller to rotate. During the rotation of the cleaning roller, the dust accumulated in the equipment shell enters the cleaning grooves. When the cleaning grooves are downward, the dust falls out of the cleaning grooves and enters the ash storage box, thus cleaning the dust accumulated in the equipment shell.

[0007] According to the aforementioned environmentally friendly recycled aluminum alloy smelting device, two triangular blocks with right-angled cross-sections are symmetrically fixedly connected to the bottom of the inner wall of the equipment shell, with the hypotenuses of the two blocks facing each other. The two triangular blocks are located at opposite ends of the inner wall of the equipment shell, and the bottom of the hypotenuses of the blocks extend to the outlet sidewall. Several equidistant limiting grooves are provided on the side ends of the triangular blocks, and these grooves penetrate the two blocks. The bottom of the filter plate is located in the limiting groove and is slidably connected to the sidewall of the limiting groove. The triangular blocks cause dust accumulated in the equipment shell to gather on the surface of the cleaning roller, improving the cleaning effect on the dust inside the equipment shell.

[0008] According to the aforementioned environmentally friendly recycled aluminum alloy smelting device, the triangular block is a hollow aluminum alloy structure, and its surface is coated with a corrosion-resistant coating. This reduces the weight and processing cost of the triangular block, while ensuring its resistance to sulfur oxides in the exhaust gas, thus extending its service life.

[0009] According to the aforementioned environmentally friendly recycled aluminum alloy smelting device, a sealing plate is provided on the side of the equipment shell, and the sealing plate penetrates the equipment shell and extends into the equipment shell. Bolts are provided on the surface of the sealing plate, and the sealing plate is fixedly connected to the equipment shell by the bolts. The sealing plate allows the equipment shell to be opened, facilitating cleaning of the inside of the equipment shell and the filter plate.

[0010] According to the aforementioned environmentally friendly recycled aluminum alloy smelting device, the ash storage box has a door on its side, which extends through the ash storage box and into its interior. One end of the door is hinged to the ash storage box for rotational connection. The door facilitates the cleaning of dust from the ash storage box by workers.

[0011] According to the aforementioned environmentally friendly recycled aluminum alloy smelting device, the outer shell of the device and the inner wall of the ash storage box are respectively coated with a smooth nano-composite ceramic coating. The nano-composite ceramic coating improves the corrosion resistance of the outer shell and the ash storage box while preventing excessive dust accumulation on their inner walls.

[0012] According to the aforementioned environmentally friendly recycled aluminum alloy smelting device, the lower center of the filter plate is provided with an arc-shaped groove that fits against the surface of the cleaning roller, and the outer end of the cleaning roller is rotatably connected to the side wall of the arc-shaped groove. This prevents the cleaning roller from affecting the filtration effect of the filter plate on the exhaust gas.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the dust removal mechanism filters the dust and impurities in the exhaust gas generated by the smelting furnace, the spray tower adsorbs the sulfur oxides in the exhaust gas, and the motor in the dust removal mechanism drives the dust removal roller to rotate, cleaning the dust accumulated at the bottom of the equipment shell into the ash storage box, thus avoiding the accumulation of dust from clogging the filter plate.

The exhaust gas enters the equipment shell 11 of the dust removal mechanism 2, where the filter plate 12 filters the dust in the exhaust gas. At the same time, the motor 10 drives the cleaning roller 13 to rotate. As the cleaning groove 17 of the cleaning roller 13 gradually rises, the dust accumulated inside the equipment shell 11 enters the cleaning groove 17. As the cleaning groove 17 moves downward with the rotation of the cleaning roller 13, the dust falls from the cleaning groove 17 into the ash storage box 9. The exhaust gas after dust removal enters the spray tower 1 to remove sulfur oxides and is finally discharged to the outside.
