Description

Technical Field

[0001] This utility model relates to the technical field of aluminum ingot production, and in particular to a powder coating device for aluminum ingot production. Background Technology

[0002] Aluminum is the world's second largest non-ferrous metal in terms of both production and consumption, after steel. Due to its lightweight nature and increasingly wide range of applications, aluminum production is increasing year by year. Currently, the production process for aluminum ingots involves first melting molten aluminum, then pouring the molten aluminum into a mold, and finally removing the ingot after cooling and solidification. High-utility aluminum ingots are produced primarily from recycled aluminum. The molten aluminum flowing from the furnace often carries aluminum dross, which needs to be blocked by a plugging column to retain the molten aluminum. Workers then scrape off the dross and reopen the plugging column to allow the molten aluminum to flow down and form the ingot. Before plugging the plugging column, talcum powder needs to be applied to its surface to facilitate cleaning of any adhering aluminum dross after plugging. Currently, workers hold the plugging column at an angle, scoop up talcum powder, pour it onto the column, rotate the column, and then pour more talcum powder. This not only causes talcum powder to scatter everywhere but is also inconvenient to operate. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a powdering device for aluminum ingot production.

[0004] This utility model provides a powder feeding device for aluminum ingot production, used for powder feeding onto blocked columns. It includes a frame 1, with powder boxes 2 symmetrically arranged at the top front and back of the frame 1. A partition 3 is provided inside the powder box 2 to accommodate the blocked column. The partition 3 divides the powder box 2 into a powder accumulation trough and a powder drop trough. A fixing block 4 is provided at the top of the powder box 2. An auger 5 driven by a motor 8 and parallel to the powder box 2 is rotatably arranged between the powder box 2 and the fixing block 4. A pipe fitting 6 is provided outside the auger 5. Both the auger 5 and the pipe fitting 6 pass through the partition 3.

[0005] Furthermore, an inlet groove 6.2 is provided on the upper side of the left end of the pipe fitting 6, a drop groove 6.3 is provided on the lower side of the right end of the pipe fitting 6, and drop holes 6.1 are provided at equal intervals on the bottom of the pipe fitting 6. The drop groove 6.3 and the drop holes 6.1 are located at the powder drop groove, and the inlet groove 6.2 is located at the powder accumulation groove.

[0006] Furthermore, the bottom of the partition 3 is provided with an arc-shaped groove.

[0007] Furthermore, the top of each of the two powder boxes 2 is fitted with a cover plate 7 that covers the powder discharge tray.

[0008] Furthermore, the motor 8 is mounted on the cover plate 7, and toothed pulleys are keyed to the output shaft of the motor 8 and the two screw conveyors 5. The toothed pulleys are connected to each other by a toothed belt 9.

[0009] Furthermore, the powder box 2 has a powder outlet hole at the bottom, and a plug 10 is provided at the powder outlet hole.

[0010] The advantages of this invention are as follows: The talcum powder is conveyed to the powder collection trough via an auger and falls onto the reclining blocking column. The talcum powder then returns to the powder accumulation trough, making the operation simple, clean, and tidy. A partition supports the blocking column and divides the powder box into the powder collection trough and the powder collection trough. The arc-shaped groove design allows the talcum powder sliding off the blocking column to return to the powder collection trough, preventing accumulation in the powder collection trough and ensuring its unobstructed flow. As the auger rotates, the talcum powder enters the pipe from the inlet and is conveyed to… Above the pipe fitting, talcum powder falls from the drop hole onto the plug column to complete the powdering of the plug column. Excess talcum powder falls from the highest drop trough into the powder drop trough. The cover plate can prevent the talcum powder in the powder drop trough from being thrown away by the rapidly rotating plug column. The motor drives the toothed pulley on the output shaft to rotate, and the toothed pulley on the output shaft drives the toothed pulley of the auger to rotate through the toothed belt, thereby driving the auger to rotate to transport talcum powder to the powder drop trough. Removing the plug allows the talcum powder to come out from the powder outlet of the powder box. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0020] See Figures 1 to 7 This utility model provides a powdering device for aluminum ingot production, used for powdering blocked columns. It includes a frame 1, with powder boxes 2 symmetrically arranged at the top front and back of the frame 1. A partition 3 is provided inside the powder box 2 to accommodate the blocked column, supporting it. The partition 3 divides the powder box 2 into a powder accumulation trough and a powder discharge trough. An arc-shaped groove is provided at the bottom of the partition 3, allowing talcum powder sliding off the blocked column to return to the powder accumulation trough, preventing accumulation in the discharge trough and ensuring its unobstructed flow. A fixing device is provided at the top of the powder box 2. A screw conveyor 5, driven by a motor 8 and parallel to the powder box 2, is rotatably installed between the fixed block 4, the powder box 2, and the fixed block 4. The screw conveyor 5 is fitted with a pipe 6. Both the screw conveyor 5 and the pipe 6 pass through the partition 3. Talc powder is poured into the powder collection trough, and the plug is placed in the powder drop trough. The motor drives the screw conveyor to rotate, transporting the talc powder in the powder collection trough to the powder drop trough, so that the talc powder falls onto the plug. The plug is manually rotated to ensure that the powder is fully distributed. The talc powder that has fallen back into the powder collection trough is kept clean and tidy, which improves the automation of powder feeding.

[0021] See Figure 5 , Figure 7 The upper left side of the pipe fitting 6 has an inlet groove 6.2, and the lower right side of the pipe fitting 6 has a drop groove 6.3. The bottom of the pipe fitting 6 has drop holes 6.1 at equal intervals. The drop groove 6.3 and drop holes 6.1 are located at the powder drop trough, and the inlet groove 6.2 is located at the powder accumulation trough. As the auger rotates, talcum powder enters the pipe fitting from the inlet groove and is transported to the top of the pipe fitting. The talcum powder falls from the drop holes onto the plug column to complete the powdering of the plug column. Excess talcum powder falls from the highest drop groove into the powder drop trough.

[0022] The top of each of the two powder boxes 2 is fitted with a cover plate 7 that covers the powder discharge trough. The cover plate is designed to prevent the talcum powder in the powder discharge trough from being flung away by the rapidly rotating plug; generally, a gentle rotation of the plug is sufficient.

[0023] The motor 8 is mounted on the cover plate 7. Toothed pulleys are keyed to the output shaft of the motor 8 and the two augers 5. The toothed pulleys are connected to each other by a toothed belt 9. The motor drives the toothed pulleys on the output shaft to rotate, and the toothed pulleys on the output shaft drive the toothed pulleys of the augers to rotate through the toothed belt, thereby driving the augers to rotate and transport talc powder to the powder dropper.

[0024] The powder box 2 has a powder outlet at the bottom, and a plug 10 is installed at the powder outlet. Removing the plug will allow the talcum powder to come out of the powder outlet of the powder box.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
