Description

Technical Field

[0001] The present invention relates to the technical field of quantitative supply of molten aluminum, and specifically, to a device for detecting the capacity of molten aluminum in a furnace and quantitatively supplying the same. Background Art

[0002] Currently, in the domestic automotive industry, communication industry, construction industry, decoration, etc., there is a rapid development, and the usage amount of metal alloys is also increasing. Considering that aluminum alloy products have a low density, high strength, and strong die-casting performance, and are suitable for die-casting complex structures, they are widely used. Therefore, the requirements for equipment for melting and storing molten aluminum are also getting higher and higher. In the prior art, molten metal is stored in a holding furnace, and then a dosing machine is used to transfer the molten metal to the feed inlet of a die-casting machine.

[0003] During the transfer process of molten aluminum, it is necessary to use a die-casting dosing machine to pour the molten metal from a metering furnace through a holding furnace into the corresponding die-casting machine while the molten metal is kept warm in the holding furnace. This consumes a large amount of energy, has a high cost, and is not environmentally friendly.

[0004] Moreover, during the transfer process of molten aluminum, dross is extremely likely to form on the surface of the molten aluminum. When the molten aluminum with dross is transferred to the feed inlet of the die-casting machine, the dross will inevitably mix into the molten aluminum and participate in the die-casting process, which will cause defects such as pores and inclusions inside the die-castings, greatly affecting the quality of the die-castings.

[0005] In view of this, we propose a device for detecting the capacity of molten aluminum in a furnace and quantitatively supplying the same. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In the device for detecting the aluminum liquid capacity and quantitatively supplying it in the furnace, by controlling the output end of the rotating motor to drive the eccentric wheel to rotate, the pressure exerted by the eccentric wheel on the pressure rod gradually decreases during rotation.

[0019] 3. In the device for detecting the aluminum liquid capacity and quantitatively supplying it in the furnace, by controlling the output end of the servo motor to drive the lead screw to rotate, when the lead screw rotates, it drives the moving frame to move on its surface. During the movement of the moving frame, it drives the cylinder to move. When the cylinder moves, the long rod slidably arranged on its inner wall is subjected to the extrusion force of the elastic member, so that the scraper provided at the bottom of the long rod is closely attached to the bottom of the temporary storage box. Since both sides of the scraper are in a slope shape, during the movement of the scraper, it can scrape the scum attached to the bottom of the temporary storage box, so that the scum attached to the bottom of the temporary storage box is collected into the residue box, preventing the scum from blocking the temporary storage box, and thus facilitating the supply of aluminum liquid during subsequent processing.

[0035] The purpose of this embodiment is to provide a device for detecting the capacity of aluminum liquid in a furnace and quantitatively supplying it. Refer to Figures 1-7As shown, it includes an aluminum liquid tank 100, a first cylinder 200 is provided on the top of the aluminum liquid tank 100, a fixed frame 201 is provided on the piston rod at the end of the first cylinder 200, a hopper 202 is provided at the bottom of the fixed frame 201, a rotating shaft is provided on both sides of the hopper 202 to penetrate the side wall of the fixed frame 201, and a first gear 203 is provided on the surface of the rotating shaft, a quantitative cavity 101 is provided on one side of the aluminum liquid tank 100, a pressing machine is provided below the quantitative cavity 101, and a quantitative supply component 300 is provided above the quantitative cavity 101, and the quantitative supply component 300 is controlled to make the aluminum liquid quantitatively input into the pressing machine feed port, and the aluminum liquid tank 1 A temporary storage box 102 is provided inside 00, a through hole is opened at the bottom of the center of the temporary storage box 102, a filter screen 106 is provided on the surface of the through hole, the through hole is connected to the quantitative cavity 101 by a connecting pipe, a metering valve 103 is provided on the surface of the connecting pipe, through grooves are provided on both sides of the temporary storage box 102, a sealing component 400 is provided on the surface of the through groove, and the sealing component 400 seals the surface of the through groove in a natural state, a residue box 104 is provided at the bottom of the through groove, and a scraping component 500 is provided above the temporary storage box 102, and the scraping component 500 is used to scrape and collect the residue deposited at the bottom of the temporary storage box 102.

[0036] During the supply of aluminum liquid, the aluminum liquid is poured into the temporary storage box 102 to filter the scum. Since the temperature inside the aluminum liquid box 100 is relatively high, in order to facilitate the pouring of the aluminum liquid in the hopper 202, a rack 105 is provided inside the aluminum liquid box 100. When the hopper 202 drives the first gear 203 to move up in the vertical direction, the first gear 203 meshes and rotates on the side wall of the rack 105. The piston rod at the end of the first cylinder 200 is controlled to drive the hopper 202 to move down in the vertical direction. During the movement of the hopper 202, the aluminum liquid box 100 is pressed against the aluminum liquid. 00 is filled with aluminum liquid. When the hopper 202 is filled, the piston rod at the end of the first cylinder 200 is controlled to drive the hopper 202 to move up in the vertical direction. When the hopper 202 moves to the rack 105 and continues to move up, the first gear 203 meshes and rotates on the side wall of the rack 105. The first gear 203 drives the hopper 202 to rotate when rotating. When the hopper 202 is tilted, the aluminum liquid contained therein is poured into the temporary storage box 102 to filter the scum, thereby realizing automatic pouring of the aluminum liquid and improving the safety of the aluminum liquid supply operation.

[0037] To facilitate the control of the quantitative supply of molten aluminum, the quantitative supply assembly 300 includes a pressure rod 301 provided at the top of the quantitative cavity 101. A plug is provided at the bottom of the pressure rod 301. A return spring 302 is provided between the pressure rod 301 and the quantitative cavity 101. By pressing the pressure rod 301, the plug is driven to seal the bottom of the quantitative cavity 101. A rotating motor 303 is provided on one side of the molten aluminum tank 100. An eccentric wheel 304 is provided at the output end of the rotating motor 303. The eccentric wheel 304 is in contact with the top of the pressure rod 301. By controlling the output shaft of the rotating motor 303 to drive the eccentric wheel 304 to rotate, the pressure rod 301 is moved in the vertical direction. When quantitatively supplying molten aluminum, the metering valve 103 quantitatively conveys the molten aluminum flowing through the connecting pipe into the quantitative cavity 101. When it is necessary to fill the molten aluminum into the feed inlet of the briquetting machine, by controlling the output end of the rotating motor 303 to drive the eccentric wheel 304 to rotate, the pressure applied by the eccentric wheel 304 to the pressure rod 301 gradually decreases during the rotation process. The pressure rod 301 is driven by the acting force of the return spring 302 to drive the plug away from the bottom of the quantitative cavity 101, so that the molten aluminum inside the quantitative cavity 101 flows out quantitatively into the briquetting machine, realizing the quantitative supply of the molten aluminum required by the briquetting machine.

[0038] During the supply of molten aluminum, since the internal space of the temporary storage tank 102 is relatively large, when the molten aluminum is supplied through the connecting pipe, in order to improve the supply speed, therefore, the sealing assembly 400 includes support rods 401 provided on both sides of the inner wall of the temporary storage tank 102. A second gear 402 is provided at the center of the support rod 401. A stop block 403 is provided on the surface of the support rod 401. The stop block 403 is in a slope shape and rotates on the surface of the support rod 401. Torsion springs 404 are provided on both sides of the support rod 401. Both sides of the torsion spring 404 are fixed to the stop block 403 and the inner wall of the temporary storage tank 102 respectively. A second cylinder 405 is provided above the second gear 402. A toothed plate 406 is provided on the piston rod at the end of the second cylinder 405. Control the piston rod at the end of the second cylinder 405 to drive the toothed plate 406 to move in the vertical direction. When the toothed plate 406 moves, it drives the second gear 402 to rotate. In the natural state, the stop block 403 is attached to the surface of the through slots provided on both sides of the temporary storage tank 102 under the action of the torsion spring 404, thereby blocking the through slots, forming an enclosed shape between the stop block 403 and the temporary storage tank 102. By providing the stop block 403 on both sides of the temporary storage tank 102, the molten aluminum poured into the temporary storage tank 102 is gathered at the center of the temporary storage tank 102. When it is necessary to transport the molten aluminum into the quantitative cavity 101, the supply speed of the molten aluminum can be accelerated. Since there is scum in the molten aluminum, when the molten aluminum in the temporary storage tank 102 is supplied to the inside of the quantitative cavity 101 through the filter screen 106, the scum remains at the bottom of the temporary storage tank 102. Control the piston rod at the end of the second cylinder 405 to drive the toothed plate 406 to move downward in the vertical direction. When the toothed plate 406 moves, it drives the second gear 402 to rotate, so that the support rod 401 drives the stop block 403 to rotate. When the stop block 403 rotates, it is on both sides of the temporary storage tank 102, so that the through slots provided on both sides of the temporary storage tank 102 are in an open state, and the residue on the surface of the temporary storage tank 102 is swept into the residue box 104 for collection, avoiding the residue blocking the filter screen 106 and affecting the conveying efficiency of the molten aluminum.

[0039] After the quantitative input of the molten aluminum is completed, all the molten aluminum temporarily stored in the temporary storage tank 102 flows into the interior of the quantitative cavity 101 through the filter screen 106. Since scum is likely to be generated on the surface of the molten aluminum during the processing, in order to facilitate the removal of the scum and prevent the scum from adhering to the bottom of the temporary storage tank 102 during subsequent processing, resulting in the blockage of the filter screen 106 and affecting the supply of molten aluminum, when collecting the residue attached to the bottom of the temporary storage tank 102, it is necessary to empty the molten aluminum in the molten aluminum tank 100 and have the operator clean it, which is rather troublesome and affects the production efficiency. Therefore, the scraping assembly 500 includes a servo motor 501 provided on one side of the temporary storage tank 102. A lead screw 502 is provided at the output end of the servo motor 501. A moving frame 503 is provided on the surface of the lead screw 502. When the lead screw 502 rotates, it drives the moving frame 503 to reciprocate horizontally. A cylinder 504 is provided at the bottom of the moving frame 503. A long rod 505 is slidably provided on the inner wall of the cylinder 504. An elastic member 506 is provided between the cylinder 504 and the long rod 505. A scraper 507 is provided at the bottom of the long rod 505. When the scraper 507 moves, it fits with the bottom of the temporary storage tank 102. When the supply of the molten aluminum temporarily stored in the temporary storage tank 102 is completed, by controlling the output end of the servo motor 501 to drive the lead screw 502 to rotate, when the lead screw 502 rotates, it drives the moving frame 503 to move on its surface. During the movement of the moving frame 503, it drives the cylinder 504 to move. When the cylinder 504 moves, the long rod 505 slidably provided on its inner wall is subjected to the extrusion force of the elastic member 506, so that the scraper 507 provided at the bottom of the long rod 505 fits tightly with the bottom of the temporary storage tank 102. Since both sides of the scraper 507 are in a slope shape, during the movement of the scraper 507, it can scrape the scum attached to the bottom of the temporary storage tank 102. When the scraper 507 is scraping, the piston rod at the end of the second cylinder 405 drives the toothed plate 406 to move downward in the vertical direction. During the movement of the toothed plate 406, it drives the stop block 403 to rotate, so that the through groove below the stop block 403 is in an open state. When the scraper 507 drives the scum to move to the through groove and fall, the rapid collection and removal of the scum at the bottom of the temporary storage tank 102 is realized, which is convenient for the supply of molten aluminum during subsequent processing.

[0040] During specific use, the piston rod at the end of the first cylinder 200 is controlled to drive the hopper 202 to move downward in the vertical direction. During the movement of the hopper 202, the molten aluminum in the molten aluminum tank 100 is contained. When the hopper 202 is full, the piston rod at the end of the first cylinder 200 is controlled to drive the hopper 202 to move upward in the vertical direction. When the hopper 202 moves to the rack 105 and continues to move upward, the first gear 203 meshes and rotates on the side wall of the rack 105. When the first gear 203 rotates, it drives the hopper 202 to rotate. When the hopper 202 is tilted, the molten aluminum contained inside it is poured into the temporary storage tank 102 for filtering out scum, thereby realizing the automatic pouring of molten aluminum and improving the safety of the molten aluminum supply operation. At the same time, the metering valve 103 is used to quantitatively control the volume of molten aluminum. The metering valve 103 quantitatively conveys the molten aluminum flowing through the connecting pipe to the quantitative cavity 101. When it is necessary to fill the molten aluminum into the feed inlet of the pressure feeding machine, the output end of the rotating motor 303 is controlled to drive the eccentric wheel 304 to rotate. During the rotation of the eccentric wheel 304, the pressure exerted on the pressure rod 301 gradually decreases. The pressure rod 301 drives the plug away from the bottom of the quantitative cavity 101 under the action of the return spring 302, so that the molten aluminum inside the quantitative cavity 101 flows out quantitatively into the pressure feeding machine, realizing the quantitative supply of the molten aluminum required by the pressure feeding machine.

[0041] By arranging the blocking blocks 403 on both sides of the temporary storage tank 102, the molten aluminum poured into the temporary storage tank 102 is gathered at the center of the temporary storage tank 102. When it is necessary to convey the molten aluminum into the quantitative cavity 101, the supply speed of the molten aluminum can be accelerated. Since there is scum in the molten aluminum, when the molten aluminum inside the temporary storage tank 102 is supplied to the inside of the quantitative cavity 101 through the filter screen 106, the scum remains at the bottom of the temporary storage tank 102. The piston rod at the end of the second cylinder 405 is controlled to drive the toothed plate 406 to move downward in the vertical direction. During the movement of the toothed plate 406, it drives the second gear 402 to rotate, so that the support rod 401 drives the blocking block 403 to rotate. When the blocking block 403 rotates, it is on both sides of the temporary storage tank 102, so that the through grooves provided on both sides of the temporary storage tank 102 are in an open state.

[0042] At the same time, the output end of the servo motor 501 is controlled to drive the lead screw 502 to rotate. When the lead screw 502 rotates, it drives the moving frame 503 to move on its surface. During the movement of the moving frame 503, it drives the cylinder 504 to move. When the cylinder 504 moves, the long rod 505 slidably arranged on its inner wall is subjected to the extrusion force of the elastic member 506, so that the scraping plate 507 provided at the bottom of the long rod 505 is in close contact with the bottom of the temporary storage tank 102. Since both sides of the scraping plate 507 are in a slope shape, during the movement of the scraping plate 507, it can scrape the scum attached to the bottom of the temporary storage tank 102, and collect the scum attached to the bottom of the temporary storage tank 102 into the residue box 104, preventing the scum from blocking the temporary storage tank 102, and thus facilitating the supply of molten aluminum during subsequent processing.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, which are not used to limit the present invention.
