Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot production, in particular to a dust reduction chamber used for aluminum ingot production. Background Art

[0002] Aluminum ingots are raw materials used in daily industry. During the production of aluminum ingots, a large amount of dust is generated. This dust mainly comes from multiple links such as raw material processing, smelting, casting, and processing. For example, dust is generated during the crushing, screening, and transportation of bauxite. During the smelting process, dust is generated due to the volatilization of alumina and other additives. If the cooling speed is too fast, the reaction time between the surface of the aluminum ingot and oxygen is shortened, which easily forms more dust. Therefore, the air in the factory needs to be treated for dust reduction.

[0003] Existing dust suppression devices only collect dust through dust bags. However, the dust-carrying gas is not sufficiently decelerated within the dust suppression chamber, and the dust cannot be sufficiently decelerated, gathered, and settled. A large amount of dust is still discharged with the air, resulting in poor dust suppression effectiveness. Therefore, it is necessary to design a dust suppression chamber for aluminum ingot production to address this problem. Utility Model Content

[0004] The purpose of the present utility model is to provide a dust removal chamber for aluminum ingot production to solve at least one technical problem existing in the above-mentioned background technology.

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

[0006] A dust suppression chamber for aluminum ingot production, comprising:

[0007] A mounting frame, wherein a dust suppression cylinder is fixedly mounted on the top of the mounting frame, an air guide tube is mounted on the top of the dust suppression cylinder, a first speed reduction plate is fixedly mounted on the top of the inner wall of the dust suppression cylinder, and a second speed reduction plate is fixedly mounted on the bottom of the inner wall of the dust suppression cylinder;

[0009] A dust collecting bag is arranged on a transfer vehicle, a positioning frame is fixedly installed on the transfer vehicle, the inner side of the positioning frame is in contact with the dust collecting bag, and a pulley is installed at the bottom of the transfer vehicle.

[0010] Preferably, the bottom of the dust suppression cylinder is configured to be funnel-shaped, and the dust suppression cylinder is symmetrically distributed about the center of the mounting frame.

[0013] Preferably, the second speed reduction plate is circular in top view, and has an arc-shaped plate-like structure in front view. The height of the center of the second speed reduction plate is higher than the height of the edge of the second speed reduction plate.

[0014] Preferably, the center of the second speed reduction plate and the center of the dust suppression cylinder are on the same vertical line, and the diameter of the second speed reduction plate is larger than the inner diameter of the bottom end of the dust suppression cylinder.

[0019] 1. This utility model significantly reduces the speed of air entering the air duct through the first deceleration plates, which are evenly distributed within the air duct. This, combined with the second deceleration plates, ensures sufficient air deceleration. The inclined design of the first deceleration plates and the curved design of the second deceleration plates prevent dust residue.

[0020] 2. The utility model positions the pulling belt through the positioning hanging plate, so that the dust collecting bag can be widely opened, which is convenient for collecting dust. At the same time, the dust collecting bag can be quickly disassembled and replaced by a transfer vehicle, which is convenient for the transfer of the dust collecting bag.

The above structural design can prevent dust from gathering on the first speed reduction plate 4, and the contact area with the air is large. A second speed reduction plate 5 is fixedly installed on the bottom of the inner wall of the dust reduction cylinder 2;

[0033] A dust collecting cylinder 2 is provided with a dust collecting pipe 6 at the bottom end of the dust collecting cylinder 2, a positioning hanging plate 7 is fixedly installed on the side of the middle of the dust collecting pipe 6, the end of the positioning hanging plate 7 is fitted with the top of the pulling belt 8, the bottom end of the pulling belt 8 is connected and fixed with the top edge of the dust collecting bag 9, a bag tube 10 is fixed at the top center of the dust collecting bag 9, the bag tube 10 is fitted with the bottom end of the dust collecting pipe 6, and a clamp 11 is installed on the outside of the bag tube 10;

[0034] The dust collecting bag 9 is arranged on a transfer vehicle 12 , a positioning frame 13 is fixedly mounted on the transfer vehicle 12 , the inner side of the positioning frame 13 is in contact with the dust collecting bag 9 , and a pulley 14 is installed at the bottom of the transfer vehicle 12 .

[0037] In one of the preferred embodiments, the center of the second deceleration plate 5 is on the same vertical line as the center of the dust reduction cylinder 2, and the diameter of the second deceleration plate 5 is larger than the inner diameter of the bottom end of the dust reduction cylinder 2.

When the air flows downward in the dust suppression cylinder 2, it first passes through the dust suppression cylinder 2. Figure 2 The air is greatly decelerated by the first deceleration plates 4, which are arranged at a medium angle and at equal vertical intervals. The air then passes through the second deceleration plates 5, where it is decelerated again. The dust carried in the air is then gathered and settled after being greatly decelerated. The dust is then collected in the dust collecting bag 9 through the dust exhaust pipe 6 at the bottom of the dust suppression cylinder 2.
