DETAILED DESCRIPTION

[0034] The following is a detailed description of a waste aluminum profile impurity cleaning and purification device of the present invention in conjunction with the accompanying drawings.

[0035] like Figure 1-5As shown, an embodiment of a waste aluminum profile impurity cleaning and purification device of the present invention includes a base 1 and an insulating shell 2 arranged on the base 1, a furnace 3 for melting the aluminum profile into aluminum liquid (aluminum melt) is installed on the top of the insulating shell 2, and the furnace 3 is the prior art, wherein a rotating seat 4 is provided in the insulating shell 2, and the axis of rotation of the rotating seat 4 is arranged vertically, and a plurality of lifting platforms 6 that can move up and down are provided on the rotating seat 4, and the lifting platforms 6 are arranged in a row around the axis of rotation of the rotating seat 4, and a separation tank body 8 for separating the aluminum liquid from the impurities therein is placed on each lifting platform 6; after the aluminum profile is melted into aluminum liquid by the furnace 3, the aluminum liquid is poured into the separation tank body 8, and finally separated by the separation tank body 8, and the specific separation process is described in detail below.

[0036] A tank cover 9 that can move up and down and is used to cover the tank mouth of the separation tank body 8 is provided in the heat-insulating shell 2, and the melting furnace 3 is provided with a refractory tank material pipe 10 that extends downward into the heat-insulating shell 2, and a refractory material guide pipe 11 that is connected to the refractory tank material pipe 10 is provided on the tank cover 9. The top of the refractory material guide pipe 11 is slidably arranged with the bottom end of the refractory tank material pipe 10, and the bottom end extends to the bottom of the tank cover 9; when the rotating seat 4 rotates to drive one of the separation tank bodies 8 to be placed directly under the tank cover 9, and then the tank cover 9 is controlled to move downward, the refractory material guide pipe 11 slides on the refractory tank material pipe 10 to cover the tank mouth of the separation tank body 8. At this time, the bottom end of the refractory material guide pipe 11 extends into the separation tank body 8, and the melting furnace 3 transports the aluminum liquid melted from the aluminum profile to the separation tank body 8 through the refractory tank material pipe 10 and the refractory material guide pipe 11, and then separates the aluminum liquid and impurities through the separation tank body 8. The tank cover 9 and the separation tank body 8 are both made of fire-resistant heat-insulating materials. The tank cover 9 covers the tank mouth of the separation tank body 8 in order to insulate the aluminum liquid in the separation tank body 8 and to prevent the aluminum liquid from being oxidized by the air as much as possible.

[0037] In addition, the insulation shell 2 is provided with a discharge pipe 15 placed directly below the tank cover 9 and used to guide the purified aluminum liquid. A vertically arranged refractory pipe body 17 is provided on the lifting platform 6. The top of the refractory pipe body 17 is connected to the separation tank body 8 placed on the lifting platform 6. The top of the discharge pipe 15 is provided with a connecting end 16 for connecting with the bottom end of the refractory pipe body 17 after it is lowered; a valve mechanism 18 for controlling the on and off of the refractory pipe body 17 is installed on the lifting platform 6. After the separation tank body 8 is placed on the lifting platform 6, the bottom of the separation tank body 8 is connected to the refractory tube body 17. At this time, the valve mechanism 18 makes the refractory tube body 17 closed, and the rotating seat 4 is controlled to rotate, so that the separation tank body 8 can be driven to be placed between the control tank cover 9 and the discharge pipe 15, that is, directly below the tank cover 9, and then the tank cover 9 is controlled to move downward to cover the tank mouth of the separation tank body 8. After covering, the tank cover 9 continues to move downward, exerting a downward force on the lifting platform 6, thereby pushing the lifting platform 6 to slide downward on the rotating seat 4, so that the bottom end of the refractory tube body 17 is connected to the connecting end 16 and connected to the discharge pipe 15, and then the aluminum liquid is poured into the separation tank body 8 for separation and purification. The valve mechanism 18 is controlled The refractory tube body 17 is opened, and the purified aluminum liquid is guided to the subsequent cooling device (not shown in the figure) through the refractory tube body 17 and the discharge pipe 15, and the separated impurities remain in the separation tank body 8; the tank cover 9 is controlled to reset upward, and the lifting platform 6 automatically resets upward, so that the bottom end of the refractory tube body 17 is separated from the connecting end 16. After the tank cover 9 is reset to be separated from the separation tank body 8, the rotating seat 4 is controlled to rotate again, and the next separation tank body 8 is driven to between the control tank cover 9 and the discharge pipe 15, and the next separation and purification process can be carried out. The separation tank body 8 containing impurities is driven to the designated position to facilitate its removal from the insulation shell 2, and then the new separation tank body 8 is placed on the corresponding lifting platform 6.

[0038] In this embodiment, in order to better extract impurities from the aluminum liquid, the tank cover 9 is equipped with a blowing mechanism 19 for blowing air to remove impurities from the aluminum liquid in the separation tank body 8, and is also equipped with an exhaust mechanism 20 for extracting gas from the separation tank body 8.

[0039] By setting the blowing mechanism 19, the present invention uses the "bubble flotation method" to remove impurities and purify the aluminum liquid. The specific impurity removal and purification process is as follows: after the aluminum liquid is poured into the separation tank 8, the blowing mechanism 19 is operated. The blowing mechanism 19 introduces argon, nitrogen and other inert gases that do not react chemically with the aluminum melt into the aluminum liquid, so that tiny bubbles are formed in the aluminum liquid. These bubbles will float in the aluminum liquid. During the floating process, the bubbles will absorb impurities in the aluminum liquid and be taken out of the aluminum liquid as the bubbles escape, and finally a scum layer 87 (such as Fig. 9After the specified blowing time, the blowing mechanism 19 is stopped, and the valve mechanism 18 is operated to open the refractory tube body 17. The purified aluminum liquid is discharged through the refractory tube body 17 and the discharge pipe 15, and the scum layer 87 remains at the bottom of the separation tank body 8, thereby completing the purification of the aluminum liquid and achieving the purpose of purifying the aluminum liquid.

[0040] In addition, a plurality of slide grooves 5 are formed on the side of the rotating seat 4, and a plurality of lifting platforms 6 are slidably set at different slide grooves 5, and each slide groove 5 is provided with a spring 7 for applying an upward thrust to the lifting platform 6; when the tank cover 9 applies a downward force to the lifting platform 6 and pushes it to move downward, the spring 7 is compressed. When the force on the lifting platform 6 stops, the lifting platform 6 is pushed upward to return to its original position under the action of the compressed spring 7.

[0041] In order to place the separation tank body 8 at a designated position on the lifting platform 6 and connect with the refractory tube body 17, a limiting protrusion 61 is provided on the top surface of the lifting platform 6, and a positioning groove 81 is formed at the bottom of the separation tank body 8 for the limiting protrusion 61 to be embedded in. In the process of placing the separation tank body 8 on the lifting platform 6, after the limiting protrusion 61 is embedded in the positioning groove 81, the bottom of the separation tank body 8 is automatically connected with the top of the refractory tube body 17, which facilitates the accurate placement of the separation tank body 8; and in the process of driving the separation tank body 8 to move, the position of the separation tank body 8 will not be offset.

[0042] In order to control the rotation of the rotating seat 4, a first gear 21 is installed at the bottom of the rotating seat 4, a third stepping motor 22 is installed at the base 1, and a second gear 23 meshing with the first gear 21 is installed on the output shaft of the third stepping motor 22, and the number of teeth of the second gear 23 is smaller than the number of teeth of the first gear 21. When the third stepping motor 22 is operated, the rotating seat 4 can be controlled to rotate under the transmission of the first gear 21 and the second gear 23; and under the effect of the transmission ratio, the rotation speed of the rotating seat 4 is reduced and the output torque is increased, thereby improving the accuracy of driving the separation tank body 8 to be placed at the designated position between the control tank cover 9 and the discharge pipe 15, and preventing misalignment.

[0043] In order to control the automatic up and down movement of the tank cover 9, a vertically arranged slide rail 12 is provided on the inner side wall of the heat-insulating shell 2, and the tank cover 9 is equipped with a sliding frame 13, which is slidably arranged on the slide rail 12. The heat-insulating shell 2 is provided with a control mechanism 14 for controlling the up and down movement of the tank cover 9. By operating the control mechanism 14, an upward or downward force can be applied to the tank cover 9, so that the tank cover 9 can stably slide up and down on the slide rail 12 through the sliding frame 13.

[0044] Furthermore, the blowing mechanism 19 includes a gas guiding pipe 191 which is provided on the tank cover 9 and arranged vertically, the bottom end of the gas guiding pipe 191 extends to below the tank cover 9, and is connected to a plurality of gas guiding branch pipes 192 at its bottom end, and a nozzle 193 is provided on the gas outlet end of each gas guiding branch pipe 192; after the tank cover 9 is controlled to move downward to cover the separation tank body 8 and the aluminum liquid is poured in, the nozzle 193 on the gas guiding branch pipe 192 is immersed in the aluminum liquid, so that the inert gas is passed into the gas guiding pipe 191, and under the action of the plurality of gas guiding branch pipes 192 and the nozzle 193, the inert gas is fully blown into the aluminum liquid.

[0045] In addition, the gas guide main pipe 191 is rotatably arranged on the tank cover 9. When the tank cover 9 covers the separation tank body 8 and the gas guide branch pipe 192 is immersed in the aluminum liquid, the aluminum liquid is blown while the gas guide main pipe 191 is controlled to rotate. The aluminum liquid can be stirred through the gas guide branch pipe 192, thereby increasing the opportunity and area for the bubbles to contact the aluminum liquid, so that the bubble surface can fully absorb the impurity particles and dissolved gas in the aluminum liquid.

[0046] In order to control the rotation of the gas guide pipe 191, the tank cover 9 is equipped with a driving motor 194. The output shaft of the driving motor 194 is connected to the gas guide pipe 191 through a bevel gear set 195. The bevel gear set 195 consists of a pair of bevel gears meshing with each other. The pair of bevel gears are respectively arranged on the output shafts of the gas guide pipe 191 and the driving motor 194. When the driving motor 194 is operated, the rotation of the gas guide pipe 191 is controlled under the transmission action of the bevel gear set 195.

[0047] The top of the gas guide main pipe 191 is connected with a plurality of gas supply pipes 196, which are used to respectively provide different inert gases (such as argon, nitrogen, etc.). The bottom of each gas supply pipe 196 is rotatably arranged with the top of the gas guide main pipe 191, and the top of each gas supply pipe 196 is provided with a first connecting pipe 197 connected thereto so as to slide up and down, and the end of each first connecting pipe 197 is provided with a gas supply pump 198. Different gas supply pumps 198 are controlled separately, and when the required inert gas needs to be provided, the corresponding gas supply pump 198 is operated, and the inert gas enters the gas supply pipe 196 through the first connecting pipe 197, and then enters the gas guide main pipe 191; and when the tank cover 9 is controlled to move up and down, the gas supply pipe 196 slides up and down on the first connecting pipe 197.

[0048] Furthermore, the exhaust mechanism 20 includes a plurality of exhaust pipes 201 arranged on the tank cover 9 and extending to the bottom of the tank cover 9. The top of each exhaust pipe 201 is provided with a second connecting pipe 202 which is connected thereto and slides up and down, and the end of each second connecting pipe 202 is provided with an exhaust pump 203. When the air supply pump 198 is operated, the exhaust pump 203 is operated, and the gas blown into the aluminum liquid is extracted through the exhaust pipe 201 after escaping, and then guided through the second connecting pipe 202 to extract the inert gas for recycling.

[0049] like Figure 6 As shown, the control mechanism 14 includes a mounting plate 141 arranged in the heat-insulating shell 2 and a connecting block 143 arranged on the tank cover 9. The mounting plate 141 is provided with a threaded rod 142 which is vertically arranged and fixedly connected to the connecting block 143 at the bottom end. The top end of the threaded rod 142 passes through the heat-insulating shell 2 to extend outward. The mounting plate 141 is rotatably provided with a threaded sleeve 144, and the threaded sleeve 144 is threadedly connected to the threaded rod 142. Because the threaded rod 142 is fixedly arranged with the connecting block 143, when the threaded sleeve 144 is driven to rotate, the threaded rod 142 can be controlled to move up and down, thereby moving the tank cover 9 up and down together, so as to control the tank cover 9 to automatically lift and lower.

[0050] A first servo motor 146 is installed on the outside of the insulation shell 2 through a mounting seat 145, and the output shaft of the first servo motor 146 is connected to the threaded sleeve 144 through a transmission component 147. The transmission component 147 can be a structure of a gear and a toothed belt. By running the first servo motor 146 and transmitting through the transmission component 147, the threaded sleeve 144 can be driven to rotate.

[0051] like Figure 7-8 As shown, the valve mechanism 18 includes a valve block 181 movably arranged in the refractory tube body 17. The valve block 181 is formed with a through hole. The valve block 181 is controlled to move so that the through hole on the valve block 181 is connected or disconnected with the refractory tube body 17 to control the on and off of the refractory tube body 17. A connecting shaft 182 is rotatably arranged in the limiting protrusion 61. One end of the connecting shaft 182 passes through the refractory tube body 17 and is fixedly arranged with the valve block 181, and the other end extends to the outside of the limiting protrusion 61. The lifting platform 6 is equipped with a second servo motor 183. The output shaft of the second servo motor 183 is connected to the end of the connecting shaft 182 extending to the outside of the limiting protrusion 61. The second servo motor 183 is operated to drive the connecting shaft 182 to rotate, thereby driving the valve block 181 to move in the refractory tube body 17 to control the on and off of the refractory tube body 17. The limiting protrusion 61 can not only place the connecting shaft 182 to prevent it from being damaged by excessive temperature, but also cooperate with the positioning groove 81 to limit the separation tank body 8.

[0052] In addition, a separation groove 82 for depositing impurities (i.e., a slag layer 87) is formed at the inner bottom of the separation tank body 8, and a leakage port 83 for the aluminum liquid to leak out is formed at the central position of the bottom of the separation tank body 8, and the top opening of the leakage port 83 is higher than the bottom surface of the separation groove 82; after the air blowing and stirring are completed, the control valve block 181 is activated, the refractory tube body 17 is opened, and the purified aluminum liquid flows out through the leakage port 83, and is discharged through the discharge pipe 15 under the guidance of the refractory tube body 17. After the purified aluminum liquid is discharged, the impurities (i.e., the slag layer 87) are retained in the separation groove 82 and cannot flow out from the leakage port 83, thereby realizing the separation of the aluminum liquid and the impurities.

[0053] A connecting groove 84 is formed at the bottom of the separation tank body 8, which is connected to the leakage port 83 and is used to connect with the top of the refractory tube body 17; after the separation tank body 8 is placed on the lifting platform 6, it is connected to the top of the refractory tube body 17 through the connecting groove 84, so that the leakage port 83 is connected to the refractory tube body 17.

[0054] In the process of separation, in order to prevent the scum layer 87 from flowing out from the leakage port 83, an "umbrella"-shaped shielding member 86 is provided directly above the leakage port 83. The radial dimension of the shielding member 86 is larger than the diameter of the leakage port 83. The shielding member 86 is fixed in the separation tank body 8 through the fixing member 85. The circumference of the shielding member 86 is lower than the top opening of the leakage port 83 and higher than the bottom surface of the separation tank 82. The purified aluminum liquid flows out through the gap between the shielding member 86 and the leakage port 83 (such as Fig. 9 As shown in FIG. 8 , during the outflow process, the shielding member 86 blocks the scum layer 87 , causing the scum layer 87 to spread out in a ring shape and eventually be collectively deposited in the separation tank 82 .

[0055] In addition, the heat-insulating shell 2 is formed with a take-in and put-out port 24 for removing the separation tank body 8 with impurities remaining inside from the lifting platform 6. After the purification is completed, the rotating seat 4 is controlled to rotate, and the separation tank body 8 is placed directly below the take-in and put-out port 24. The take-in and put-out device (not shown in the figure) placed next to the purification device is operated to remove the separation tank body 8 with impurities remaining inside from the lifting platform 6 and take it out of the heat-insulating shell 2. After taking it out, the new separation tank body 8 can be placed on the lifting platform 6. A cover 25 is provided at the take-in and put-out port 24 to cover it.
