Description

Technical Field

[0001] The present invention relates to the technical field of aluminum slag treatment, and in particular to a waste slag treatment device for aluminum alloy smelting and a treatment method thereof. Background Art

[0002] A variety of by-products are produced during the smelting and forming of aluminum alloys. As the main by-product of the aluminum industry, aluminum ash is produced in all aluminum melting processes, and the aluminum content in it accounts for about 1-12% of the total loss during aluminum production and use. In the past, people regarded aluminum slag as waste and dumped it, which not only caused a waste of aluminum resources but also brought environmental problems. Therefore, finding economical and effective methods to utilize and manage aluminum slag will not only improve the economic benefits of the aluminum industry, but also have an important impact on achieving sustainable economic and social development while achieving effective recycling of resources.

[0003] The treatment process of aluminum slag is generally divided into hot ash treatment and cold ash treatment. The hot ash treatment of aluminum slag uses forklift to transport ash, fully enclosed treatment device, cold ash mixing system, rapid cooling mechanism, screening, and then re-melting. The treatment is relatively clean and thorough, with a residual aluminum content of 2%-5%; the cold ash treatment system adopts crushing-screening-ball milling-screening (separating aluminum particles with a particle size of 2-3mm)-re-melting (when the product requires low iron, iron must be removed before entering the furnace). Since the aluminum ash treatment method is a dry system, it produces a lot of dust. Therefore, the entire system needs to be closed, with a dust cover and a cyclone dust collector to ensure a normal working environment. It can also be connected with hot ash treatment, which can improve efficiency. The treated aluminum particles can be directly used for smelting. Aluminum ash can be used as a raw material for the production of aluminum chloride series water purifiers, so that waste aluminum can be recycled to its full potential.

[0004] Regardless of whether the aluminum slag is subjected to cold ash treatment or hot ash treatment, the aluminum slag produced during the aluminum alloy smelting process needs to be quickly cooled before it can be processed.

[0005] At present, in the prior art, there are generally three ways to cool aluminum slag: natural cooling. Natural cooling is one of the simplest aluminum slag cooling methods. After the aluminum slag is taken out from the high temperature state, it is placed in the natural environment to dissipate heat through natural convection and conduction, so that its temperature gradually decreases. The reduction speed is slow and it is not suitable for use in the factory; water cooling is a commonly used and efficient aluminum slag cooling method. It uses the high thermal conductivity and heat absorption capacity of water to quickly cool the aluminum slag. In specific operations, the cooling water can be directly sprayed on the surface of the aluminum slag by spraying. The advantages of water cooling are fast cooling speed and obvious effect. It is suitable for occasions where aluminum blocks are quickly cooled; gas cooling is a commonly used non-contact aluminum slag cooling method. Common gas cooling methods include airflow cooling and gas purge cooling. Airflow cooling is to send cooling gas to the surface of the aluminum block through a fan or air duct, and use the thermal conductivity of the gas to take away the heat. Gas purge cooling is to spray cooling gas at high speed to the surface of the aluminum block through a nozzle, and take away the heat by the kinetic energy of the cooling gas.

[0006] After searching, the Chinese patent application number 202120071105.1 discloses an aluminum slag cooling separation and recovery device, including a feeding mechanism and a cooling cylinder mechanism, wherein the feeding mechanism is arranged at the input end of the cooling cylinder mechanism, and the output end of the cooling cylinder mechanism is provided with a rotating discharging mechanism, and the discharging port of the rotating discharging mechanism is equipped with a slag separation and recovery mechanism, and the slag separation and recovery mechanism includes a slag separation mechanism, a small slag recovery mechanism, a large slag recovery mechanism and a negative pressure dust suction structure, wherein the small slag recovery mechanism, the large slag recovery mechanism and the negative pressure dust suction structure are respectively arranged at different output positions of the slag separation mechanism. The disadvantage of the above patent is that there is a small amount of liquid aluminum in the aluminum slag at a high temperature. During the cooling process, the liquid aluminum solidifies into a solid and solidifies on the machine, making it difficult to discharge after cooling.

[0007] In order to ensure rapid cooling of the high-temperature state of aluminum slag and avoid aluminum solidification on the machine, a waste slag treatment device and a treatment method for aluminum alloy smelting are proposed. Summary of the invention

[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] Example: A waste slag treatment device for aluminum alloy smelting, such as Figure 1-7 As shown, it includes a cooling box 100, a conical feed port 101 is fixedly connected to the cooling box 100, the conical feed port 101 is used to dump high-temperature aluminum slag, the inlet is small to avoid dust flying, and the aluminum slag can accurately fall to a designated position, a discharge port 102 is fixedly connected below the cooling box 100, and a screening device is arranged at the bottom of the discharge port 102 (it can screen and classify the aluminum slag according to the size of the aluminum slag through a vibrating screen, and the screening device is a prior art and is not shown in the figure), and the upper layer of the aluminum slag screened by the screening device is aluminum chips, which can be recycled, and the lower layer is powder; A cooling carrier plate 200 is arranged inside the cooling box 100, and support baffles 202 are fixedly connected on both sides of the cooling carrier plate 200, and one side of the support baffle 202 is fixedly connected to the inner wall of the cooling box 100; the cooling carrier plate 200 is processed with uniformly distributed screening holes 203, and the screening holes 203 are in the shape of a frustum with a large diameter at the top and a small diameter at the bottom. It is worth noting that the frustum-shaped screening holes 203 can allow smaller aluminum slag to pass through them, so that small-sized substances in the aluminum slag fall through the screening holes 203. Because they are small in size, the heat can be The heat exchange with the air in the surrounding environment is carried out, that is, gas cooling, while the large aluminum slag is left on the cooling carrier plate 200, and its heat is exchanged by water cooling to make it cool quickly. The cooling carrier plate 200 is also processed with a heat exchange cavity 204 that is staggered horizontally and vertically. The heat exchange cavity 204 is not connected with the screening hole 203. The two sides of the cooling carrier plate 200 are processed with a circulating water pipe 201, which is connected to an external water source. The heat exchange cavity 204 and the circulating water pipe 201 are connected to each other for circulating water to circulate and exchange heat; It also includes a rotating cylinder 300 rolling on the cooling carrier plate 200, which is used to squeeze the aluminum slag on the cooling carrier plate 200 and crush the aluminum slag adhered to the cooling carrier plate 200. The rotating cylinder 300 is fixedly connected with uniformly distributed support columns 301 around it. The support columns 301 are in a truncated cone shape that matches the shape of the screening holes 203 and are used to squeeze and crush the aluminum slag inside the screening holes 203. The rotating cylinder 300 is fixedly connected with uniformly distributed crushing pointed rods 302 around it. The crushing pointed rods 302 are used to scrape and crush the aluminum slag on the surface of the cooling carrier plate 200. It is worth noting that the number of single-row support columns 301 in the axial direction of the rotating cylinder 300 is equal to the number of single-row screening holes 203 on the cooling carrier plate 200, so that the aluminum slag in each screening hole 203 is crushed and squeezed by the support columns 301. In some schemes, an electric guide rail 103 is provided inside the cooling box 100, and an electric slider on the electric guide rail 103 is fixedly connected to a fixed connecting rod 303, and a fixed connecting plate 304 is fixedly connected to the fixed connecting rod 303. The two ends of the rotating connecting cylinder 300 are rotatably connected to the outer wall of the fixed connecting rod 303. It is worth noting that the fixed connecting plate 304 is always vertically downward under the action of gravity and the clamping of the electric sliders on both sides. A plurality of lifting grooves 305 are processed inside the rotating connecting cylinder 300, and a hole cleaning component 500 is arranged inside the lifting groove 305. The hole cleaning component 500 is spirally distributed on the surface of the rotating connecting cylinder 300, and is used to deeply clean and crush the aluminum slag inside the screening hole 203. Specifically, the hole cleaning component 500 When moving into the screening hole 203, the fixed connecting plate 304 squeezes the hole cleaning component 500 inside the rotating connecting cylinder 300 so that the hole cleaning component 500 goes deep into the screening hole 203 for squeezing and crushing operation. It should be noted that the multiple hole cleaning components 500 distributed in a spiral shape have at least one hole cleaning component 500 for deep squeezing and crushing operation for each row of screening holes 203 on the cooling carrier plate 200, so as to avoid multiple deep squeezing and crushing operations on a single row of screening holes 203 so that multiple hole cleaning components 500 are stuck in the screening hole 203 at the same time, and a small number of support columns 301 cannot play a supporting role in the screening hole 203, so that the rotating connecting cylinder 300 cannot roll on the cooling carrier plate 200; Furthermore, the hole cleaning component 500 includes a second elastic telescopic column 502 fixed on the inner wall of the rotating connecting tube 300, a load-bearing connecting column 501 fixed at the telescopic end of the second elastic telescopic column 502, a positioning connecting plate 504 movable in the lifting groove 305, and a rotating connecting rod 503 fixed on the positioning connecting plate 504. The bottom of the load-bearing connecting column 501 is fixedly connected to the telescopic connecting rod 505, the telescopic connecting rod 505 is provided with a thread, and the rotating connecting rod 503 is provided with a thread groove that meshes with the thread on the telescopic connecting rod 505. The second elastic telescopic column 502 has an extended state and a compressed state. When the second elastic telescopic column 502 is in the extended state, the positioning connecting plate 504 is located at the top of the lifting groove 305. When the second elastic telescopic column 502 is in the compressed state, the positioning connecting plate 504 is located at the bottom of the lifting groove 305 and the telescopic connecting rod 505 enters the rotating connecting rod 503 so that The rotating connecting rod 503 rotates. It should be noted that when the fixed connecting plate 304 is not in contact with the bearing connecting column 501, the second elastic telescopic column 502 is in an extended state. When the bearing connecting column 501 moves to the lower part of the rotating connecting cylinder 300, the bearing connecting column 501 and the fixed connecting plate 304 come into contact. At this time, the second elastic telescopic column 502 is in a compressed state. During the compression process, the bearing connecting column 501 squeezes the second elastic telescopic column 502 downward, and the bearing connecting column 501 moves downward with the rotating connecting rod 503 and the locking connecting plate 504 until the locking connecting plate 504 is located at the bottom of the lifting groove 305. At this time, the bearing connecting column 501 continues to move downward into the interior of the rotating connecting rod 503. Under the transmission of the thread, the rotating connecting rod 503 and the locking connecting plate 504 rotate to deeply squeeze and crush the current screening hole 203, and clean the solid matter adhered therein. In order to ensure that the rotating connecting cylinder 300 can roll smoothly on the cooling carrier plate 200, the solution adopted in this embodiment is that only one of each column of support columns 301 on the rotating connecting cylinder 300 is a hole cleaning component 500, so that the support columns 301 play a supporting role in the screening holes 203 to move the rotating connecting cylinder 300 on the cooling carrier plate 200, that is, when the rotating connecting cylinder 300 moves on the cooling carrier plate 200, each column of support columns 301 will enter each column of screening holes 203, and the support columns 301 play a role in supporting the rotating rotating connecting cylinder 300 under the truncated cone shape of the screening holes 203, so as to prevent the rotating connecting cylinder 300 from getting stuck on the cooling carrier plate 200. Furthermore, there is only one hole cleaning component 500 on each column of support columns 301. In order to allow a hole cleaning component 500 thereon to perform deep extrusion and crushing with each screening hole 203 of the corresponding row on the cooling carrier plate 200, the present embodiment adopts the following scheme: a support connecting plate 205 is fixedly connected to one side of the cooling carrier plate 200, and the support connecting plate 205 is processed with evenly distributed long holes. It is worth mentioning that the long holes on the support connecting plate 205 facilitate the support column 301 to be inserted into the circular hole on the limiting slide plate 400, so that the limiting slide plate 400 continues to move on the support connecting plate 205, that is, the support column 301 moves in the long hole at this time, and the support The supporting plate 205 is slidably connected to a limit slide 400, and a circular hole identical to the screening hole 203 is provided on the limit slide 400, and an arc plate matching the arc of the rotating connecting tube 300 is fixedly connected to one side of the limit slide 400, and an arc notch is provided on the arc plate, and a limit folding rod 401 is fixedly connected to one side of the arc plate, and a first elastic telescopic column 402 is fixedly connected to the limit folding rod 401, and an arc-shaped electromagnet 403 matching the arc of the fixed connecting rod 303 is fixedly connected to the telescopic end of the first elastic telescopic column 402, and is used to form a fixed relationship with the fixed connecting rod 303 after power is turned on; it should be noted that the rotating connecting tube 300 moves to When the limiting slide plate 400 is on, the support column 301 directly below is stuck in the circular hole of the limiting slide plate 400, and the support column 301 obliquely below is stuck in the circular arc notch of the arc plate, so that the rotating connecting tube 300 can no longer rotate to the right under the blocking position of the two. At this time, the fixed connecting rod 303 is located inside the arc electromagnet 403. After the arc electromagnet 403 is energized, the two form a fixed relationship. At this time, when the electric slider on the electric guide rail 103 moves with the rotating connecting tube 300, the arc electromagnet 403 and its limiting slide plate 400 will move synchronously. At this time, the rotating connecting tube 300 is in the circular hole of the limiting slide plate 400 and the circular arc notch of the arc plate. The electric guide rail 103 is provided with two position sensors for sensing the position of the electric slider on the electric guide rail 103. One position sensor is located at the position where the bottom of the long hole on the supporting connecting plate 205 is projected onto the electric guide rail 103, and is used to receive the position of the electric slider and send it to the terminal so that the arc electromagnet 403 stops being energized. The other position sensor is located at the right end of the electric guide rail 103, and is used to receive the position of the electric slider and send it to the terminal so that the arc electromagnet 403 stops being energized. In some schemes, the number of screening holes 203 in each row on the cooling carrier plate 200 is n, and the angle between two adjacent support columns 301 on the rotating connecting cylinder 300 is α, that is, when the rotating connecting cylinder 300 rotates by an angle of α, the new support column 301 on the rotating connecting cylinder 300 is inserted into the corresponding screening hole 203, and the old support column 301 is pulled out from the corresponding screening hole 203, and this rotation is recorded as one rotation. Then, when the electric slider on the electric guide rail 103 drives the rotating connecting cylinder 300 to move from the right side to the left side, the rotating connecting cylinder 300 rotates counterclockwise n times, and then when the rotating connecting cylinder 300 moves from the right side to the left side again, the rotating connecting cylinder 300 rotates clockwise (n+1) times. Therefore, the angle of the rotating connecting cylinder 300 will change each time it moves back and forth, resulting in that the hole cleaning component 500 with only one in each row and column can perform an extrusion and crushing operation on the screening holes 203 in each row and column on the cooling carrier plate 200 in n reciprocating movements, such as Figure 8 As shown, specifically, in this embodiment, the number of screening holes 203 in each row is preferably 8, and there are 8 columns of support columns 301 on the rotating cylinder 300, and the two are the same in number, so that the same screening holes 203 can be repeatedly subjected to deep squeezing and crushing operations in one reciprocating motion, thereby improving the effect.

[0029] When this embodiment is in use, the staff transfers the aluminum slag into the processing system through a forklift, and then the aluminum slag is transferred to the top of the conical feed port 101 and poured into the cooling box 100. The aluminum slag first reaches the cooling support plate 200, and the smaller materials fall through the screening hole 203, and heat exchange occurs with the air. The staff connects the circulating water pipe 201 to the external water source, so that the cooling water circulates back and forth into the heat exchange chamber 204 of the cooling support plate 200, and the aluminum slag is water-cooled in a non-contact manner, with good cooling effect and fast cooling speed, and no pollution to the water, which can be recycled. Then the system terminal drives the electric slider on the electric guide rail 103 to move, driving the rotating connecting cylinder 300 to perform preliminary crushing treatment on the aluminum slag on the cooling support plate 200; When working, the electric slider is located at the right end of the electric guide rail 103. At this time, the arc electromagnet 403 is energized and fixedly connected to the fixed connecting rod 303. The electric slider moves the rotating connecting cylinder 300 and the limiting slide plate 400 to the left. At this time, the rotating connecting cylinder 300 does not rotate under the synchronous movement of the limiting slide plate 400 and the rotating connecting cylinder 300. When the electric slider moves to the position sensor on the left and the limiting slide plate 400 also moves to the concave part of the long hole of the supporting connecting plate 205, the arc electromagnet 403 receives the signal and stops energizing. The arc electromagnet 403 and the fixed connecting rod 303 are no longer fixed. At this time, when the electric slider drives the fixed connecting rod 303 to move left, the rotating connecting cylinder 300 will rotate counterclockwise (such as Figure 8As shown), the support columns 301 at 2 positions on the rotating connecting cylinder 300 enter the corresponding screening holes 203, the electric slider continues to move, and the rotating connecting cylinder 300 continues to rotate until the electric slider moves to the left end. At this time, the support column 301 at 1 position on the rotating connecting cylinder 300 enters the corresponding screening hole 203, and then the electric slider moves to the right with the fixed connecting rod 303, and the rotating connecting cylinder 300 rotates clockwise until the rotating connecting cylinder 300 moves to the edge of the cooling carrier plate 200. At this time, the support columns 301 at 2 positions on the rotating connecting cylinder 300 are inserted into the corresponding screening holes 203, and then the electric slider moves to the right, and the support column 301 at 1 position on the rotating connecting cylinder 300 is inserted into the long hole of the supporting connecting plate 205. At this time, the position sensor senses the electric slider, A stop power signal is transmitted to the arc electromagnet 403 (determining that the arc electromagnet 403 is in a stop power state), and the electric slider continues to move to the right until it moves to the initial position, that is, the right end of the electric guide rail 103. At this time, the position sensor senses the position of the electric slider, and transmits a power signal to the arc electromagnet 403, so that the arc electromagnet 403 and the fixed connecting rod 303 form a fixed relationship, and the above operation can be repeated. During the above operation, the fixed connecting plate 304 is always downward to squeeze the hole cleaning component 500 directly below the rotating connecting cylinder 300, and the corresponding screening hole 203 is deeply squeezed and crushed. The cooled aluminum slag is initially crushed and extruded, and then sent to the screening machine through the discharge port 102 for screening, and the aluminum chips are recycled.

[0030] A method for treating a waste slag treatment device used in aluminum alloy smelting, comprising: S1: Connect the external water source to the circulating water pipe 201, connect the electric guide rail 103 to the screening machine, turn on the power, and use a forklift to deliver the aluminum slag into the device; S2: an external water source passes water into the circulating water pipe 201, and water enters the heat exchange chamber 204 of the cooling carrier plate 200 to quickly cool the aluminum slag, and then the electric guide rail 103 is started to use the electric slider to drive the rotating cylinder 300 to roll on the cooling carrier plate 200 to squeeze and crush the aluminum slag; S3: Start the screening machine to screen the aluminum slag after extrusion and crushing; S4: After the screening is completed, the screened upper aluminum chips are recycled and reused.
