Description

Technical Field

[0001] The present invention relates to the technical field of aluminum ash processing equipment, and in particular to an aluminum ash deamination device. Background Art

[0002] Aluminum is a widely used metal. It's typically produced electrolytically, refined to remove impurities, and then cast into ingots. These ingots are then directly or melted into various profiles. During the refining or aluminum processing process, deslagging agents are added and nitrogen is introduced. This produces not only qualified aluminum but also slag, or aluminum ash.

[0003] Aluminum ash contains approximately 20% aluminum. To recycle it, it needs to be deaminated.

DETAILED DESCRIPTION

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] The embodiment of the present invention provides an aluminum ash deamination device, referring to Figures 1 to 3 As shown, it includes a deamination tank body 100 and an aluminum ash feeding device. The deamination tank body 100 is provided with an aluminum ash inlet, and the aluminum ash feeding device includes a storage bin 200, a conveying mechanism 300, and a dredging mechanism 400. The storage bin 200 of this embodiment includes a storage chamber 201 and a discharge pipe 210. The storage chamber 201 is used to store aluminum ash. The discharge pipe 210 is located at the bottom of the storage bin 200, and the inner hole of the discharge pipe 210 is connected to the storage chamber.

[0020] The conveying mechanism 300 of this embodiment includes a conveying pipe 310, a motor 320, and an auger 330. The conveying pipe 310 is provided with an input port connected to the bottom end of the discharge pipe 210, and an output port connected to the aluminum ash inlet. The motor 320 is fixedly mounted on the outside of the conveying pipe 310, while the auger 330 is located within the conveying pipe 310. The motor 320 can be driven to rotate the auger 330, thereby conveying the aluminum ash from the input port to the output port.

[0021] The dredging mechanism 400 of this embodiment includes a dredging rod 410 arranged in the storage chamber 201, the bottom end of the dredging rod 410 passes through the discharge pipe 210 and extends into the feed pipe 310, and a cam is fixedly sleeved on the central axis of the auger 330 to abut against the bottom end of the dredging rod. A first elastic member 220 is provided between the dredging rod 410 and the storage bin 200, and the first elastic member 220 applies a downward thrust to the dredging rod 410, and a material baffle plate 411 is provided on the dredging rod 410. When the low point of the cam supports the dredging rod 410, the material baffle plate 411 blocks the intersection of the inner hole of the discharge pipe 210 and the storage chamber 201.

[0022] Based on the above-mentioned overall structure, when the aluminum ash deamination device of this embodiment is in use, the aluminum ash to be deaminated can be placed in the storage bin 200 in advance; when aluminum ash needs to be added to the deamination tank body 100, the motor 320 on the feed pipe 310 can be turned on, and the motor 320 will drive the dredging rod 410 to move up and down, so that the aluminum ash in the storage bin falls into the feed pipe 310 through the input port; at the same time, the motor 320 can also drive the auger 330 to rotate, and the auger 330 drives the aluminum ash to move toward the output port, and enters the deamination tank body 100 through the aluminum ash feed port on the deamination tank body 100.

[0023] Compared with the prior art, the aluminum ash deamination device of this embodiment can automatically add aluminum ash into the deamination tank body 100 by turning on the motor 320 on the feed pipe 310, replacing the process of the staff manually adding aluminum ash into the deamination tank body 100. Moreover, by providing the above-mentioned dredging mechanism 400, the dredging rod 410 can periodically reciprocate with the rotation of the auger 330 shaft. The weight of the aluminum ash dropped into the feed pipe 310 in a single reciprocating movement of the dredging rod 410 is approximate, so that the weight of the aluminum ash transported into the deamination tank body 100 is approximately proportional to the number of rotations of the motor 320 shaft. Therefore, the weight of the aluminum ash added to the deamination tank body 100 can be controlled by controlling the number of rotations of the motor 320 shaft. That is, the aluminum ash deamination device of this embodiment can also quantitatively add aluminum ash into the deamination tank body 100.

[0024] For specific structure, refer to Figure 3As shown, the storage bin 200 of this embodiment includes a bottom plate 230 and side panels connected to the sides of the bottom plate 230 and extending upward. The side panels are connected end to end, and the bottom plate 230 and the side panels enclose the aforementioned storage chamber 201. A worker can place aluminum ash into the storage chamber 201 through the opening at the top of the storage chamber 201.

[0025] refer to Figures 1 to 3 As shown, a discharge pipe 210 with a circular cross-section is fixedly provided on the lower side of the bottom plate 230, and the inner hole of the discharge pipe 210 is connected to the storage cavity, so that the aluminum ash in the storage cavity 201 can fall through the discharge pipe 210; and in this embodiment, the bottom plate 230 of the storage bin 200 is tilted, and the height of the bottom plate 230 gradually decreases towards the direction of the discharge pipe 210, that is, the discharge pipe 210 is located at the lowest point of the bottom plate 230, so that the aluminum ash in the storage cavity 201 can slide to the discharge pipe 210 by its own weight.

[0026] In this embodiment, reference Figure 2 and Figure 3 As shown, a process block 240 is fixed on the storage bin 200, and a guide hole is opened on the process block 240. The above-mentioned dredging rod 410 is installed in the guide hole and can be guided and slid in the guide hole, so that the dredging rod 410 can move in the expected direction.

[0027] refer to Figure 3 As shown, the above-mentioned baffle plate 411 is fixedly mounted on the dredging rod 410, and its diameter is larger than the inner diameter of the discharge pipe 210. When the dredging rod 410 moves downward to the lowest point, the baffle plate 411 covers the discharge pipe 210, preventing aluminum ash from continuing to fall from the discharge pipe 210 into the feed pipe 310. By providing the baffle plate 411, it is possible to prevent aluminum ash from continuously falling into the feed pipe 310, so that the weight of aluminum ash falling into the feed pipe 310 during a single reciprocating movement of the dredging rod 410 is roughly equal, so as to facilitate the delivery of a predetermined weight of aluminum ash into the deamination tank 100.

[0028] In some embodiments, reference Figure 3 As shown, a plurality of pusher plates 412 are provided on the outer periphery of the baffle plate 411. Each pusher plate 412 is spaced apart circumferentially around the baffle plate 411. One end of each pusher plate 412 is fixedly connected to the baffle plate 411, and the other end extends downward and outward. A blocking block 413 is fixedly provided at the bottom end of the baffle plate 411. When the bottom end of the pusher plate 412 abuts the bottom wall of the storage bin, the blocking block 413 is inserted into the discharge pipe 210 to seal the discharge pipe.

[0029] In this embodiment, by providing each push plate 412 and cooperating with the rotation of the dredging rod 410 described below, each push plate 412 can move the nearby aluminum ash, thereby preventing the formation of a cavity below the baffle plate 411 and affecting the aluminum ash from falling into the feed pipe 310. Due to the provision of the push plates 412, when the push plates 412 contact the bottom surface of the storage chamber 201, there is still a gap between the baffle plate 411 and the bottom surface of the storage chamber 201. By providing the above-mentioned blocking block 413 that can be inserted into the discharge pipe 210, it is possible to prevent the aluminum ash from falling into the discharge pipe 210 through the gap and then falling into the feed pipe 310 from the discharge pipe 210.

[0030] refer to Figure 2 and Figure 3 As shown, in this embodiment, a process plate 420 is fixed to the dredging rod 410. The first elastic member 220 is a first spring that is sleeved on the dredging rod 410. One end of the first spring abuts the process plate 420, and the other end abuts the guide block. When the cam pushes the dredging rod 410 upward, the process plate 420 compresses the first spring, storing energy. When the cam stops pushing the dredging rod 410, the first spring pushes the process plate 420 downward, causing the dredging rod 410 to move downward.

[0031] Simply put, by the cam pushing the clearing rod 410 upward and the first spring pushing the clearing rod 410 downward, the clearing rod 410 can move up and down alternately to clear the discharge pipe 210 and disturb the aluminum ash in the storage chamber 201, so that the aluminum ash can fall smoothly into the delivery pipe 310.

[0032] In this embodiment, reference Figure 2 and Figure 3 As shown, a plurality of guide grooves 401 are constructed on the outer circumference of the dredging rod 410. Each guide groove 401 is spaced apart circumferentially around the dredging rod 410 and extends obliquely from top to bottom. Corresponding to each guide groove 401, a plurality of guide posts 250 are fixed to the storage bin 200, each of which is inserted into a corresponding guide groove 401.

[0033] In this embodiment, by providing each guide groove 401 and corresponding guide post 250, when the dredging rod 410 moves upward or downward, due to the inclined guide groove 401, the guide post 250 will apply lateral thrust to the sidewalls of the guide groove 401, thereby causing the dredging rod 410 to rotate about its own axis. The rotation of the dredging rod 410 can drive the aforementioned pusher plates 412 to rotate during the upward movement. The pusher plates 412 stir the nearby aluminum ash, preventing the formation of a cavity below the baffle plate 411, which would affect the aluminum ash's entry into the feed pipe 310.

[0034] refer to Figure 3As shown, in this embodiment, a plurality of paddles 430 are fixedly mounted on the outer circumference of the dredging rod 410. Each paddle 430 is located within the discharge pipe 210 and is spaced apart along the circumference of the dredging rod 410. The paddles 430 can be used to scrape away aluminum ash from the inner wall of the discharge pipe 210, thereby preventing aluminum ash from accumulating on the inner wall of the discharge pipe 210 and affecting its flow into the feed pipe 310.

[0035] In this embodiment, reference Figure 2 and Figure 3 As shown, a mounting base 440 is rotatably provided on the top of the dredging rod, and an electromagnet 450 is fixed to the mounting base 440. A striking member 260 is provided on the storage to guide the lifting and lowering, and a limiting plate is fixed on the storage bin 200 and located above the striking member 260. A second elastic member 270 is provided between the striking member 260 and the limiting plate. In this embodiment, the second elastic member 270 is a spring.

[0036] Based on the above structure, when the dredging rod 410 of this embodiment is pushed upward by the cam, the electromagnet 450 can adsorb the impact member 260 and drive the impact member 260 to move upward; when the adsorption force of the electromagnet 450 on the impact member 260 is less than the thrust of the second elastic member 270 on the impact member 260, the impact member 260 can be pushed by the second elastic member 270 and impact the storage bin 200, specifically, impact the baffle fixed on the storage bin 200, thereby causing the storage bin 200 to vibrate, preventing the aluminum ash from forming a stable state in the storage bin 200 instead of falling into the feed pipe 310.

[0037] After the aluminum ash is transported into the deamination tank 100, the deamination tank 100 needs to be sealed during the deamination process so that the gas generated by the reaction is discharged from a predetermined outlet and collected. To this end, this embodiment further provides a sealing structure for sealing the aluminum ash feed port.

[0038] For specific structure, refer to Figure 1 As shown, the deamination tank body 100 is provided with an aluminum ash feed pipe 110 protruding from the surface of the deamination tank body 100. The above-mentioned aluminum ash feed port is specifically the inner hole of the aluminum ash feed pipe 110, and the above-mentioned delivery pipe 310 is provided with an output pipe 311, and the output pipe 311 extends into the aluminum ash feed pipe 110. A power unit 500 is provided on the outside of the deamination tank body 100, and a blocking member 510 connected to the output end of the power unit 500 is provided inside the deamination tank body 100. The blocking member 510 can be driven by the power unit 500 to block the inner hole of the aluminum ash feed pipe 110 or to open the inner hole of the aluminum ash feed pipe 110.

[0039] Simply put, when the power unit 500 drives the sealing part 510 to open the inner hole of the aluminum ash feed pipe 110, the aluminum ash can enter the deamination tank body 100; when the power unit 500 drives the sealing part 510 to seal the inner hole of the aluminum ash feed pipe 110, the deamination tank body 100 can be sealed to prevent the gas generated by the reaction from leaking from here.

[0040] In this embodiment, reference Figure 5 As shown, from bottom to top, the inner hole of the aluminum ash feeding pipe 110 includes a large diameter section 301 and a small diameter section 302 connected in series; the blocking member 510 includes a disc section 511, a conical section 512 provided on the disc section 511, and a cone top section 513 provided on the top surface of the conical section 512. Figure 6 As shown, when the sealing member 510 seals the inner hole of the aluminum ash feed pipe 110, the top surface of the conical section 512 abuts against the step surface between the small diameter section 302 and the large diameter section 301, and the top surface of the disc section 511 abuts against the bottom end surface of the aluminum ash feed pipe 110. In this embodiment, the power unit 500 is composed of two cylinders fixedly mounted on the deamination tank body 100. The telescopic rods of the two cylinders extend into the deamination tank body 100 and are fixedly connected to the disc section 511.

[0041] Based on the above structure, the two cylinders of this embodiment can drive the sealing member 510 to rise or fall. When the sealing member 510 rises, the top surface of the conical section 512 can abut against the stepped surface between the small-diameter section 302 and the large-diameter section 301; the top surface of the disc section 511 can abut against the bottom end surface of the aluminum ash feed pipe 110, thereby achieving a double seal on the aluminum ash feed pipe 110 and preventing gas leakage from this point. When the sealing member 510 moves downward, a gap is created between the sealing member 510 and the inner hole of the aluminum ash feed pipe 110, allowing the aluminum ash to fall into the deamination tank body 100.

[0042] refer to Figure 5 and Figure 6 In this embodiment, a center hole 501 is constructed on the bottom end surface of the disc segment 511, and a plurality of first drainage holes 520 connected to the center hole 501 are constructed on the outer circumferential surface of the cone top segment 513, and a plurality of second drainage holes 502 connected to the center hole 501 are constructed on the outer circumferential surface of the cone segment 512. The first drainage holes 520 and the second drainage holes 502 are respectively arranged at circumferential intervals around the sealing member 510, and along the direction from the center to the outside of the sealing member 510, the first drainage holes 520 and the second drainage holes 502 respectively extend obliquely downward.

[0043] Simply put, in this embodiment, a water supply pipe is fixedly provided on the deamination tank body 100 and is sealed and penetrated into the deamination tank body 100. The water supply pipe is connected to the central hole 501 on the bottom surface of the sealing member 510, and the central hole 501 is connected to each first drainage hole 520 and each second drainage hole 502; an external water pump can pump water to the central hole 501 and discharge it from each first drainage hole 520 and each second drainage hole 502.

[0044] By setting the above structure, on the one hand, the water sprayed from each first drainage hole 520 can flush the top surface of the cone section 512; the water sprayed from each second water spray hole can flush the top surface of the disc section 511; thereby preventing the aluminum ash from stopping on the top surface of the cone section 512 and the top surface of the disc section 511, and avoiding affecting the sealing effect of the sealing member 510 on the inner hole of the aluminum ash feed pipe 110. On the other hand, when falling, the aluminum ash will contact the water mist sprayed from the first water spray hole and the second water spray hole, and the aluminum ash will be carried away by the water mist when contacting the water mist, which is beneficial to the dispersion of the aluminum ash. If necessary, other mechanisms of the deamination tank body 100 can refer to the existing technology and will not be described in detail here.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
