Description

Technical Field

[0001] The invention relates to the technical field of waste aluminum treatment and waste metal recycling and reprocessing, and in particular to a recyclable waste aluminum non-ferrous metal depainting and smelting integrated device. Background Art

[0002] Aluminum is widely used. Aluminum alloys are almost everywhere in civil, military, construction, transportation, traffic, electronics and telecommunications, household appliances, electricity, machinery, etc. With the increase in production and usage, the amount of waste aluminum products is also increasing. Moreover, many aluminum products are disposable, and the time from the manufacture of products to the loss of use value is short. Therefore, these waste materials have become a source of pollution. However, the recycling and regeneration of aluminum alloys is a very complex technical work. Various aluminum products have a wide range of uses and are used in a scattered manner. How to recycle, concentrate, classify, and then realize regeneration processing are all very complicated and huge projects.

[0003] According to the known prior art, “CN 206266690 U, a waste aluminum recycling and processing equipment” records that “the utility model discloses a waste aluminum recycling and processing equipment, including a heat treatment bin, a waste aluminum processing machine body and a discharge bin. A heat treatment bin is installed inside the waste aluminum processing machine body, a heat conduction plate is fixedly installed on the top of the heat treatment bin, a driven wheel is installed on the upper right side of the heat treatment bin, and the right side of the driven wheel is connected to the driving wheel through a conveyor belt, and a cooling plate is fixedly installed on the top of the discharge bin. In the utility model, a stirring device is provided in the heat treatment bin. For the dissolved aluminum, the impurities inside are stratified due to different densities. After stirring, the aluminum is set aside so that the impurities fall into the sieve and are taken out. Finally, the heat-treated aluminum is sprayed into the discharge bin through a supercharger. Due to the same force, the impurities mixed in the aluminum water are different, so that the sprayed aluminum water and the impurities fall at different points, thereby separating the impurities.”

[0004] However, the above-mentioned waste aluminum recycling equipment of the prior art still has the following technical problems: First, the structure of the waste aluminum recycling equipment of the prior art is relatively simple, and the space design is unreasonable. In the actual waste aluminum recycling operation, the recycling and reuse value of waste aluminum such as aluminum cans and aluminum plates is particularly prominent. For aluminum cans, before heating and smelting, due to their large structure, the direct heating and smelting effect is not good, and they need to be crushed to reach a predetermined particle size. At the same time, in order to better achieve the efficiency and accuracy of waste aluminum non-ferrous metal depainting and smelting, waste aluminum recycling still needs to provide preheating of the required temperature of the crushed waste aluminum materials, but the waste aluminum recycling equipment of the prior art cannot achieve the purpose of preheating the crushed waste aluminum materials at a specified temperature when crushing aluminum products such as cans, and cannot achieve the reasonable allocation and utilization of the waste heat of heating and melting under the premise of limited heat resources to achieve the effect of efficient resource recycling and reuse. Second, in the heating and melting stage of scrap aluminum in the prior art, the relative density of aluminum is 2.70, the melting point is 660°C, and the boiling point is 2327°C. Therefore, when heated, the scrap aluminum material first melts to form molten aluminum, and other materials such as non-ferrous metals are impurities. In order to improve the purity of molten aluminum recovered from scrap aluminum, the molten aluminum mixture needs to be filtered. The conventional filtering structure is relatively simple and has poor performance. It is impossible to stir the molten aluminum mixture to ensure fluidity while efficiently filtering impurities in the molten aluminum mixture to achieve the purpose of automatic collection. The filtering and impurity collection effects are not good, which reduces the operating efficiency of scrap aluminum non-ferrous metal depainting, smelting, recycling and reuse, and also seriously affects the purity of scrap aluminum ingots.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] Example: Figures 1 to 3 As shown: A recyclable scrap aluminum non-ferrous metal depainting and smelting integrated device comprises a cellar body 1, a crushing mechanism 2 and a smelting mechanism 3. The smelting integrated device has a compact structure, a reasonable design, a high space utilization rate, and saves more than 20% of materials, which effectively reduces the manufacturing cost; the entire structure is relatively short, saving structural space, and the overall structure can compress the production line length by more than 80% compared with the traditional scrap aluminum recycling crushing process, preheating process and heating melting process. The cellar body 1 is vertically distributed and is a cylindrical structure, and a circularly distributed crushing chamber 11 and a heating chamber 12 are arranged in sequence from the inside to the outside; that is, the crushing chamber is located in the center, and the heating chamber is located outside the crushing chamber, which is a ring structure. Among them, the crushing chamber 11 and the heating chamber 12 are separated by a partition 13; the partition 13 is made of a high thermal conductivity material; the heating chamber is the main cavity for melting scrap aluminum, and the temperature is relatively high, and then heat is conducted through the partition, which is convenient for preheating the crushing chamber. The thickness ratio of the partition 13 to the outer wall of the cellar body 1 is 1:3. The purpose of such a setting is to use the space of the partition and the wall thickness to reasonably arrange the structure on the basis of ensuring stable support. The outer wall of the cellar body 1 is also covered with an insulation board 6. The purpose of such a setting is to ensure the stability of the heating and melting temperature of the heating chamber and prevent accidental touch and injury from the outside. The top of the crushing chamber 11 is provided with a feed port 14 and the bottom is provided with a discharge port 15; a hopper 111 is also connected to the feed port 14; in this way, the waste aluminum material of the waste cans enters the crushing chamber from the feed port, and the crushed material is transported to the heating chamber from the discharge port through the conveyor.

[0024] In this embodiment, the crushing mechanism 2 includes a crushing motor 21, a transmission member 22, a rotating shaft 23 and a crushing knife 24. The crushing motor 21 is fixedly installed on the cellar body 1 through a bracket, and the rotating shaft 23 is vertically distributed and rotatably arranged in the crushing chamber 11, and the upper and lower ends of the rotating shaft are connected to the cellar body through bearings. The crushing knife 24 is distributed in multiple groups up and down, and is evenly arranged on the rotating shaft 23. Among them, the rotating shaft 23 and the crushing knife 24 are two groups distributed symmetrically, and the crushing knives 24 distributed on the two rotating shafts 23 are staggered up and down; specifically, the gap between the upper and lower staggered crushing knives 24 distributed on the two rotating shafts 23 is maintained at 1-5cm. The crushing knife is made of superhard material. The purpose of such a setting is to efficiently crush the incoming waste aluminum materials such as cans through the staggered crushing knives, further improve the crushing effect of the waste aluminum materials, and then meet the requirements of uniform particle size of the waste aluminum materials, and provide a strong foundation for the subsequent rapid and efficient melting of waste aluminum.

[0025] In order to realize the synchronous rotation of the two rotating shafts and improve the crushing effect of the material, the crushing motor 21 drives the two rotating shafts 23 to maintain differential rotation in the same direction through the transmission member 22. The transmission member 22 includes a sun gear 221, a first planetary gear 222 and a second planetary gear 223. The sun gear 221 is arranged on the output shaft of the crushing motor 21, the first planetary gear 222 is arranged on one of the rotating shafts 23, and the second planetary gear 223 is arranged on the other rotating shaft 23, and the diameter of the first planetary gear 222 is kept larger than the diameter of the second planetary gear 223, and the sun gear 221 and the first planetary gear 222 and the second planetary gear 223 are all in meshing transmission. In this way, the crushing motor will drive the sun gear to rotate synchronously when it is started; the sun gear and the first planetary gear and the second planetary gear are in a positional relationship of meshing transmission, so the rotation of the sun gear will also drive the synchronous rotation of the first planetary gear and the second planetary gear. Then the synchronous rotation of the two rotating shafts is formed, that is, the high-speed rotation of the crushing knife is realized. At the same time, the diameter of the first planetary gear is greater than that of the second planetary gear, so the rotation speed of the second planetary gear and the corresponding shaft will be greater than the rotation speed of the first planetary gear, thereby forming a differential rotation of the two shafts, greatly improving the crushing efficiency of waste aluminum materials such as cans and waste aluminum plates.

[0026] In this embodiment, the crushing chamber 11 conveys the crushed aluminum scrap material of preset particle size to the heating chamber 12 through the conveying member 4. Specifically, the conveying member 4 includes a high-power suction conveyor 41, a high-temperature resistant conveying pipe 42 and a discharge pipe 43; a mounting chamber 44 is provided on one side of the partition 13; the suction conveyor 41 is fixedly installed in the mounting chamber 44 through a bracket, one end of the high-temperature resistant conveying pipe 42 is connected to the input end of the suction conveyor 41 through a flange joint, and the other end leads to the bottom of the crushing chamber 11; specifically, one end of the high-temperature resistant conveying pipe is connected to the discharge port. One end of the discharge pipe 43 is connected to the output end of the suction conveyor 41, and the other end leads to the heating chamber 12; the discharge pipe 43 is located at the upper part of the heating chamber 12, and a switch valve 45 is also provided at one end. In this way, the high-power suction conveyor and the switch valve can be opened synchronously to complete the conveyance of the aluminum scrap material in the crushing chamber to the heating chamber, providing favorable conditions for the subsequent melting and refining of the aluminum scrap in the heating chamber.

[0027] In this embodiment, the smelting mechanism 3 includes an electromagnetic induction heater 31 and a stirring member 32 of a spiral structure. The outer wall of the kiln body 1 is provided with an operating area 16 and an induction area 17 of a hollow structure and distributed up and down. The electromagnetic induction heater is a spiral structure and is connected to an electric control body to realize power-on and power-off to stop heating. The electromagnetic induction heater 31 is arranged in the induction area 17 through a bracket. The electricity required in this embodiment is realized by connecting an external power supply, and the inner wall of the heating chamber is coated with a high-temperature resistant coating. In this way, the heating chamber is heated by turning on the electromagnetic induction heater until the temperature probe in the heating chamber reaches a preset temperature T. According to actual needs, T is the temperature of the waste aluminum melt, 660-670 degrees Celsius. The heating chamber 12 and the crushing chamber 11 are connected and communicated through an exhaust pipe 18, and the heating chamber 12 is maintained at a preset temperature T, and the crushing chamber 11 is maintained at a preset temperature (0.3-0.5) T to complete the preheating operation of the waste aluminum material crushing and conveying. The exhaust pipe is arranged in the inner cavity of the partition. Preferably, an LED display screen can be provided on the outside of the cellar body for connecting a temperature measuring probe and displaying the temperature of the heating chamber and the crushing chamber in real time.

[0028] In a preferred embodiment, the exhaust pipe 18 is also sequentially installed with a fan 112, an electromagnetic control valve 113 and a one-way valve 114, so that the hot air flow can only enter the crushing chamber 11 through the heating chamber 12; the temperature probe 5 in the crushing chamber 11 maintains signal connection with the fan 112 and the electromagnetic control valve 113 respectively. The heating chamber 12 and the crushing chamber 11 are provided with a temperature probe 5, and the temperature probe 5 in the heating chamber 12 maintains signal connection with the electromagnetic induction heater 31. With such a configuration, the heat conduction effect of the partition cannot meet the good preheating effect of the crushed scrap aluminum material, and then by turning on the fan and the electromagnetic control valve, the residual heat in the heating chamber can be passed to the crushing chamber, which also realizes a kind of waste heat utilization. At the same time, a one-way valve is set in the exhaust pipe to ensure that the heat flow can only enter the crushing chamber from the heating chamber, thereby ensuring that the preheating temperature in the crushing chamber is moderate. At the same time, it also achieves the purpose of efficiently crushing aluminum products such as cans while still using the residual heat of heating and melting to preheat the crushed waste aluminum materials to a specified temperature. Compared with the waste aluminum melting heater with the same power, when the melting heating resources are equal, the heat utilization rate can be increased by about 40%.

[0029] In this embodiment, the stirring member 32 is configured to complete the stirring of the mixed liquid after the waste aluminum is heated at a preset speed, and at the same time filter the mixed liquid of the waste aluminum smelting and complete the centralized collection of impurities. Specifically, the stirring member 32 includes a support frame 33 and a rotating structure 34. The support frame 33 includes an upper ring plate 331, a lower ring plate 332, an inner connecting rod 333 and an outer connecting rod 334 formed in one piece; the upper ring plate 331 is horizontally distributed and is an annular structure, and the inner diameter is consistent with the outer diameter of the partition 13, and the outer diameter is consistent with the outer diameter of the heating chamber 12. That is, the support frame is integrally mounted on the annular partition and integrally mounted in the heating chamber. The upper ring plate 331 is also provided with a plurality of evenly distributed through holes 335, which are used to realize the transportation of materials. A mounting hole 336 is also provided between two adjacent through holes 335; the purpose of setting the mounting hole is to facilitate the overall installation and replacement and disassembly of the filter structure. The lower ring plate 332 has the same structure as the upper ring plate 331. The inner connecting rods 333 are multiple and evenly distributed in a ring shape, and are arranged on the inner sides of the upper ring plate 331 and the lower ring plate 332; the outer connecting rods 334 are also multiple and evenly distributed in a ring shape, and are arranged on the outer sides of the upper ring plate 331 and the lower ring plate 332; in this way, a stable support body can be formed, wherein bearings or ball structures can also be arranged between the upper ring plate, the lower ring plate and the partition plate to achieve a good rotation effect.

[0030] In a preferred embodiment, the rotating structure 34 includes a rotating motor 341, a driving wheel 342 and a driven wheel 343. The rotating motor 341 is fixedly installed in the operating area 16 through a bracket. The operating area is located at a higher position and does not affect the stirring operation of the molten mixed liquid of the scrap aluminum material. The driving wheel 342 is sleeved and installed on the output shaft of the rotating motor 341, and the driven wheel 343 is arranged on the outer side of the upper ring plate 331, and the driving wheel 342 and the driven wheel 343 are kept in meshing transmission. In this way, when the staff starts the rotating motor, the rotating motor will drive the driving wheel to rotate synchronously, and then the driving wheel will drive the driven wheel to rotate synchronously, that is, drive the support frame as a whole to rotate, so as to achieve uniform stirring of the aluminum-water mixture. Among them, the structures inside the heating chamber are all made of high-temperature resistant materials to ensure excellent stirring and filtering effects.

[0031] In this embodiment, the stirring member 32 also includes a filter structure 35, wherein the filter structure 35 includes a mesh plate 351, a side wing plate 352, a bottom plate 353, a cover plate 354 and a collecting plate 355. The mesh plate 351 is vertically distributed and is provided with evenly distributed filter holes 356, which are arranged in this way to filter impurities in the aluminum-water mixture. The side wing plates 352 are two distributed on the left and right, the bottom plate 353 is arranged at the bottom of the mesh plate 351, and the cover plate 354 is arranged at the top of the mesh plate 351; the collecting plate 355 is parallel to the mesh plate 351, and is connected and fixed to the bottom plate 353 and the side wing plates 352, and the collecting plate 355, the bottom plate 353, and the side wing plates 352 enclose an area to form a waste slag collection chamber. And the widths of the bottom plate 353 and the cover plate 354 are the same. The width of the bottom plate plus the thickness of the mesh plate is equal to the width of the mounting hole 336; such a setting facilitates adaptive installation to form a card-embedded installation of the filter structure as a whole. Among them, the mounting hole of the upper ring plate is a through structure, and the mounting hole of the lower ring plate is a groove structure, which is used to form a card-embedded support for the bottom of the mesh plate. The cover plate 354 is also provided with a handle 357; the purpose of such a setting is to facilitate the overall pulling out of the filter structure after the waste aluminum recycling operation, to achieve the disassembly and replacement of the filter structure, and to clean up the waste slag collected in the waste slag collection chamber. And the filter structure 35 and the mounting hole 336 are multiple groups of matching installations, and the size of the filter holes 356 of the multiple annularly distributed mesh plates 351 tends to gradually decrease in the clockwise direction. In this embodiment, the preferred filter structure and mounting hole are four groups that are evenly distributed. Taking the clockwise direction as an example, the diameter of the filter hole of the mesh plate distributed at 0 o'clock is the largest, and the diameter of the filter hole of the mesh plate distributed at 9 o'clock is the smallest. The purpose of such a setting is to realize the classified storage of waste slag of different particle sizes, improve the filtering effect of aluminum-water mixture and the purity of aluminum liquid recovered from waste aluminum; at the same time, it also facilitates the classified recycling and reprocessing of waste slag produced by waste aluminum melting.

[0032] like Figure 2As shown: In a preferred embodiment, a cooling chamber 19 is also provided at the bottom of the cellar body 1, specifically, the heating chamber and the cooling chamber are connected through an infusion tube, wherein the infusion tube is also provided with an electromagnetic switch valve for realizing the automatic discharge of aluminum liquid. A cooling plate 110 is provided in the cooling chamber 19 for cooling and molding the recycled aluminum liquid. A chute 115 is provided on the side wall of the cooling chamber 19, and a guide column 116 is provided on the side wall of the cooling plate 110, and the guide column 116 is installed in matching with the chute 115; such an arrangement plays a good guiding role, and it is convenient to take out the molded waste aluminum recycled aluminum ingots. The center of the cooling plate 110 is a groove structure, and a mold forming plate 117 is installed; the mold forming plate is of various specifications and models, and mold forming plates of different specifications and models can be selected according to different actual needs to obtain the size and shape of the aluminum ingots that meet the needs of the ordering customers, usually a rectangular structure. The outer end of the cooling plate 110 is provided with an end cover 118, and the outer side of the end cover 118 is provided with a handrail 119; wherein the end cover is adapted to the cellar structure, and the purpose of providing the handrail is to facilitate the staff or auxiliary automated traction equipment to take out the cooling plate, and then obtain the corresponding scrap aluminum recycling aluminum ingot. The motor, electromagnetic control valve, fan, etc. of this embodiment can be connected and driven by a push button switch, or can be automatically controlled by a PLC controller, wherein the working principle and technical circuit of the PLC controller are prior art for technicians in this field, and this embodiment mainly protects the connection mechanical structure of the technical solution, so it will not be repeated.

[0033] The working principle of a recyclable integrated device for depainting and smelting non-ferrous metals of scrap aluminum: First, the staff debugs the device and turns on the electromagnetic induction heater to heat the heating chamber until the temperature probe in the heating chamber reaches the preset temperature, then turns off the electromagnetic induction heater. At this time, the aluminum material of the scrap aluminum begins to melt into aluminum liquid. At the same time, the staff turns on the fan and electromagnetic control valve of the exhaust pipe to transfer the excess heat molten in the heating chamber to the crushing chamber until the temperature probe in the crushing chamber reaches the preset value, and then the fan and electromagnetic control valve of the exhaust pipe are closed. At this time, the temperature in the heating chamber and the crushing chamber are maintained in the appropriate operating temperature range.

[0034] In the next step, materials such as cans and scrap aluminum are added into the hopper, and the crushing motor is turned on simultaneously. The crushing motor will drive the staggered crushing knives to cut and crush the scrap aluminum materials entering the crushing chamber. In this process, the crushing chamber can achieve the purpose of efficiently crushing aluminum products such as cans while still using the waste heat from heating and melting to preheat the crushed scrap aluminum materials to a specified temperature. Compared with the scrap aluminum melting heater with the same power, when the melting heating resources are equal, the heat utilization rate can be increased by about 40%, which achieves the purpose of waste heat utilization, saves resources, and realizes the rational use of thermal resources.

[0035] Then the staff turns on the high-power suction conveyor and the switch valve. Under the action of strong suction, the scrap aluminum material that has been crushed and preheated begins to be transported from the discharge port of the crushing chamber along the high-temperature resistant conveying pipe to the discharge pipe, and then enters the heating chamber. At the same time, the scrap aluminum material entering the heating chamber begins to melt to form a mixture of aluminum water and waste slag. At this time, the staff turns on the rotating motor, which drives the support frame and the filter structure to rotate as a whole to form stirring. Specifically, the filter structure stirs the aluminum water mixture as a whole, and then intercepts the waste slag through the filter holes during the stirring process and collects it in the waste slag collection chamber. While the mixed liquid after the waste aluminum is heated is stirred at a preset speed through the mesh plate, the waste aluminum smelting mixed liquid is efficiently filtered and the operation of collecting impurities is completed. This further achieves the purpose of stirring the aluminum water mixture to ensure fluidity, and can also filter and purify the impurities in the aluminum water mixture efficiently, thereby completing the automated collection of pure aluminum water and waste impurities separation and classification, greatly improving the value of waste aluminum recycling and reuse.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
