Description

Technical Field

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

[0002] Aluminum ash is a solid substance containing metallic aluminum and other components produced during the production, use and recycling of electrolytic aluminum, cast aluminum or other aluminum industries. The main environmental hazards in aluminum ash are fluoride salts, chloride salts and nitrides. Fluoride salts and chloride salts can dissolve in water and pollute water resources. Nitride can react with water to produce ammonia, which seriously harms the environment.

[0003] Existing aluminum ash is usually stirred with water before calcination, and then rolled into balls through a ball-forming cylinder. The aluminum ash balls are then added to a vertical reactor for calcination. During calcination, air is blown from bottom to top into the vertical reactor by a fan to assist combustion and to cool the calcined aluminum ash balls to a certain extent. However, after the aluminum ash balls are added to the vertical reactor, they are stacked layer by layer, and the aluminum ash balls in the inner layer cannot fully contact the air, resulting in uneven calcination, which reduces the calcination quality of the aluminum ash balls. In addition, the calcined aluminum ash balls have a high temperature and need to be cooled naturally or by external cooling equipment. The waiting time for natural cooling is long, which delays the subsequent processing progress. The use of external cooling equipment needs to be set up separately, which increases production costs. In addition, the calcined aluminum ash balls also need to be transported to the cooling equipment, which increases labor costs.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0034] Reference Figure 1-Figure 7 , an aluminum ash calcining device, comprising a vertical reactor body 1, a calcining bucket 2 is fixedly connected to the inner wall of the vertical reactor body 1, and a plurality of ventilation holes 3 are opened at the lower end of the calcining bucket 2;

[0035] The calcining mechanism comprises an air inlet 4 provided at the bottom of the vertical reactor body 1, the inner wall of the air inlet 4 is rotatably connected to a rotating shaft 5, a plurality of fan blades 6 are fixedly connected to the side wall of the rotating shaft 5, two boxes 12 are symmetrically fixedly connected to the side wall of the vertical reactor body 1, the inner walls of the two boxes 12 are sealed and slidably connected to the sliding plug 13, the sliding plug 13 divides the inside of the box 12 into two parts, a pump liquid chamber 131 and a pump gas chamber 132, a vertical groove 14 is provided at the upper end of the rotating shaft 5, a plurality of jet holes 15 are provided on the inner wall of the vertical groove 14, and the top of the vertical reactor body 1 is supported by a support The frame is fixedly connected with a rotary joint 16, the upper end of the rotary joint 16 is fixedly connected with a four-way pipe 44, the upper end of the rotating shaft 5 is fixedly connected with the rotary joint 16, the inner wall of the pump air cavity 132 is fixedly connected with a one-way air inlet pipe 17, the one-way air inlet pipe 17 only allows external air to enter the pump air cavity 132, the inner wall of the pump air cavity 132 is fixedly connected with a one-way air supply pipe 18, the other end of the one-way air supply pipe 18 is connected with the four-way pipe 44, the other end of the one-way air supply pipe 18 is connected with the four-way pipe 44, the one-way air supply pipe 18 only allows the air in the pump air cavity 132 to enter the four-way pipe 44;

[0036] The temperature regulating mechanism includes a temperature sensor 41 installed on the inner wall of the vertical reactor body 1, a one-way air intake pipe 45 is fixedly connected to the inner wall of the pump air cavity 132, and the one-way air intake pipe 45 only allows the air in the vertical slot 14 to enter the pump air cavity 132, and a one-way exhaust pipe 46 is fixedly connected to the inner wall of the pump air cavity 132, and the one-way exhaust pipe 46 only allows the air in the pump air cavity 132 to be discharged, and the other end of the one-way air intake pipe 45 is connected to the four-way pipe 44, and the inner walls of the one-way air inlet pipe 17, the one-way air supply pipe 18, the one-way air intake pipe 45 and the one-way exhaust pipe 46 are all installed with electromagnetic valves, and the temperature sensor 41 is electrically connected to the electromagnetic valve through a PLC control circuit.

[0037] Furthermore, since the temperature of the aluminum ash balls needs to be maintained at about 1300 degrees Celsius during calcination, when the temperature in the vertical reactor body 1 is higher than 1300 degrees Celsius, the temperature sensor 41 will monitor and transmit a signal, and the solenoid valves on the inner walls of the one-way air inlet pipe 17 and the one-way air supply pipe 18 will be closed through the PLC control circuit, and the solenoid valves on the inner walls of the one-way air intake pipe 45 and the one-way exhaust pipe 46 will be opened. At this time, the air in the vertical reactor body 1 will be sucked into the vertical slot 14 through the multiple air injection holes 15, and then the air will enter the pump air cavity 132 through the one-way air intake pipe 45, and finally the air will be discharged through the one-way exhaust pipe 46, thereby extracting the air in the vertical reactor body 1, reducing the combustion medium, reducing the flame, and thus Lower the temperature in the vertical reactor body 1. On the contrary, when the temperature in the vertical reactor body 1 is lower than 1300 degrees Celsius, the temperature sensor 41 monitors and transmits a signal, and controls the electromagnetic valves on the inner walls of the one-way air inlet pipe 17 and the one-way air supply pipe 18 to open through the PLC control circuit, and controls the electromagnetic valves on the inner walls of the one-way air intake pipe 45 and the one-way exhaust pipe 46 to close. At this time, air will be pumped into the vertical groove 14, and the air will be sprayed into the vertical reactor body 1 through multiple jet holes 15, thereby increasing the combustion medium in the vertical reactor body 1, enhancing the calcination flame, and then increasing the temperature. Therefore, the temperature in the vertical reactor body 1 can be automatically adjusted so that the temperature is always maintained at about 1300 degrees Celsius to ensure the calcination effect of the aluminum ash balls.

[0038] The calcining mechanism also includes two first rotating rods 7 symmetrically connected to the inner wall of the vertical reactor body 1, a plurality of stirring rods 8 are fixedly connected to the side walls of the first rotating rods 7, a motor 9 is fixedly connected to the lower end of the vertical reactor body 1, the output end of the motor 9 passes through the lower end of the vertical reactor body 1 and is fixedly connected to the rotating shaft 5, the upper end of the rotating shaft 5 passes through the upper end of the calcining bucket 2, a gear ring 10 is fixedly connected to the side wall of the rotating shaft 5, and a first gear 11 is fixedly connected to one end of the first rotating rod 7 close to the rotating shaft 5, and the gear ring 10 is meshed with the first gear 11.

[0039] Furthermore, the motor 9 is started to drive the rotating shaft 5 to rotate, and then drive the multiple fan blades 6 to rotate, so that the external air is drawn into the vertical reactor body 1 through the air inlet 4, and then the air will flow from bottom to top, and the air will pass through the ventilation holes 3 to contact the aluminum ash balls, thereby playing a role in combustion. During the calcination process, the rotation of the rotating shaft 5 will synchronously drive the ring gear 10 to rotate, drive the first gear 11 to rotate, and then drive the first rotating rod 7 to rotate, drive the stirring rod 8 to rotate, and stir the aluminum ash balls in the calcination bucket 2, so that the aluminum ash balls are turned over, and then the surface of the aluminum ash balls can be fully in contact with the flame and air, thereby avoiding the stacking of aluminum ash balls, causing some parts of the aluminum ash balls to be unable to contact the flame, and causing uneven calcination of the aluminum ash balls. In addition, since solid fluoride salts are generated on the surface of the aluminum ash balls during the calcination process, when the first rotating rod 7 and the stirring rod 8 rotate and collide with the surface of the aluminum ash balls, the solid fluoride salts generated on the surface of the aluminum ash balls due to calcination will be crushed and fall off.

[0040] A driving mechanism is installed in the box body 12, and the driving mechanism includes a slider 19 slidably connected to the inner wall of the box body 12. The slider 19 is symmetrically fixedly connected to two cross bars 20 near the side wall of the sliding plug 13. The other ends of the two cross bars 20 are fixedly connected to the sliding plug 13. A first reciprocating screw 21 is rotatably connected to the inner wall of the box body 12. The side wall of the first reciprocating screw 21 is threadedly connected to the slider 19. One end of the first rotating rod 7 passes through the side wall of the box body 12 and is fixedly connected to the first reciprocating screw 21.

[0041] Furthermore, the rotation of the first rotating rod 7 will drive the first reciprocating screw 21 to rotate, driving the slider 19 to slide back and forth on the inner wall of the box body 12, and the slider 19 will drive the sliding plug 13 to slide back and forth in a sealed manner through the cross bar 20, and then the external air will be drawn into the pump air cavity 132 through the one-way air inlet pipe 17, and then the air will be squeezed into the vertical groove 14 through the one-way air supply pipe 18, and finally the air will be ejected through multiple jet holes 15 and sprayed horizontally between the aluminum ash balls, thereby increasing the contact area between the aluminum ash balls and the air, and the calcination effect is better.

[0042] Two discharge pipes 23 are symmetrically fixedly connected to the lower end of the calcining hopper 2. The discharge pipes 23 are made of materials with good thermal conductivity. The lower ends of the two discharge pipes 23 are both set through the lower end of the vertical reactor body 1, and solenoid valves are installed on the inner walls of the two discharge pipes 23. The inner walls of the discharge pipes 23 are very rough, which can increase the friction between the discharge pipes 23 and the aluminum ash balls, thereby reducing the descending speed of the aluminum ash balls in the discharge pipes 23, which is convenient for increasing the cooling time of the aluminum ash balls and improving the cooling effect.

[0043] A cooling mechanism is installed on the discharge pipe 23, and the cooling mechanism includes a cooling pipe 24 fixedly sleeved on the side wall of the discharge pipe 23. The cooling pipe 24 is made of a high-temperature resistant hose. A one-way liquid inlet pipe 25 is fixedly connected to the inner wall of the pump liquid cavity 131. The other end of the one-way liquid inlet pipe 25 is connected to an external container storing coolant, and the one-way liquid inlet pipe 25 only allows external coolant to enter the pump liquid cavity 131. The pump liquid cavity 131 is connected to the cooling pipe 24 through a one-way liquid supply pipe 26. The one-way liquid supply pipe 26 only allows the coolant in the pump liquid cavity 131 to enter the cooling pipe 24. A discharge pipe 27 is fixedly connected to the inner wall of the cooling pipe 24, and the other end of the discharge pipe 27 is arranged to penetrate the lower end of the vertical reactor body 1.

[0044] Furthermore, due to the reciprocating sealed sliding of the sliding plug 13, the external coolant will be drawn into the pump liquid chamber 131 through the one-way liquid inlet pipe 25, and then the coolant in the pump liquid chamber 131 will be squeezed into the cooling pipe 24 through the one-way liquid supply pipe 26. The coolant will exchange heat with the aluminum ash balls, thereby quickly cooling the aluminum ash balls that have just been calcined, without waiting for them to cool naturally or setting up additional cooling equipment, thereby reducing production costs.

[0045] An extrusion mechanism is installed on the vertical reactor body 1, and the extrusion mechanism includes two slide grooves 28 symmetrically opened in the vertical reactor body 1, and the inner walls of the two slide grooves 28 are slidably connected with rectangular blocks 29, and the side walls of the rectangular blocks 29 are fixedly connected with connecting rods 30. One end of the connecting rod 30 penetrates the inner wall of the vertical reactor body 1 and is fixedly connected with a vertical cylinder 31. The vertical cylinder 31 is sleeved on the side wall of the cooling pipe 24, and a plurality of extrusion heads 32 are fixedly connected to the inner wall of the vertical cylinder 31.

[0046] The extrusion mechanism also includes a second reciprocating screw 33 rotatably connected to the inner wall of the slide groove 28, the side wall of the second reciprocating screw 33 is threadedly connected to the rectangular block 29, the side wall of the first rotating rod 7 is fixedly connected to a driving wheel 34, one end of the second reciprocating screw 33 passes through the side wall of the vertical reactor body 1 and is fixedly connected to a driven wheel 35, and the driving wheel 34 and the driven wheel 35 are connected by a synchronous belt.

[0047] Furthermore, since the coolant in the cooling tube 24 often alternates between hot and cold, scale may adhere to the inner wall of the cooling tube 24, thereby affecting the heat exchange of the coolant. Therefore, during the reciprocating sliding of the rectangular block 29, the connecting rod 30 will drive the vertical cylinder 31 to move back and forth, and then the multiple extrusion heads 32 will move back and forth, continuously squeezing the cooling tube 24, causing the cooling tube 24 to bend and deform, and then the scale attached to the inner wall of the cooling tube 24 will be squeezed off, thereby improving the heat exchange effect of the coolant.

[0048] A knocking mechanism is installed in the vertical reactor body 1, and the knocking mechanism includes two second rotating rods 36 symmetrically connected to the inner wall of the vertical reactor body 1, a plurality of knocking rods 37 are fixedly connected to the side wall of the second rotating rod 36, a second gear 38 is fixedly connected to the side wall of the second rotating rod 36, a vertical rod 39 is fixedly connected to the upper end of the connecting rod 30, a rack 40 is fixedly connected to the upper end of the vertical rod 39, and the rack 40 is meshed with the second gear 38.

[0049] Furthermore, the rotation of the first rotating rod 7 will drive the driving wheel 34 to rotate, and then drive the driven wheel 35 to rotate, drive the second reciprocating screw 33 to rotate, drive the rectangular block 29 to slide back and forth on the inner wall of the slide groove 28, drive the connecting rod 30 to move back and forth, and then drive the vertical rod 39 to move back and forth, drive the rack 40 to move back and forth, and then drive the second gear 38 to rotate forward and reverse, drive the second rotating rod 36 to rotate forward and reverse, and drive multiple knocking rods 37 to rotate forward and reverse, so that they continuously knock on the calcining bucket 2, causing the calcining bucket 2 to vibrate, and the vibration will be transmitted to the aluminum ash ball, causing the aluminum ash ball to vibrate, and the solid fluoride salt on the surface of the aluminum ash ball to vibrate, thereby making it easier for the solid fluoride salt to fall off, thereby improving the removal effect of the solid fluoride salt.

[0050] A feed hopper 42 and an exhaust pipe 43 are fixedly connected to the upper end of the vertical reactor body 1 .

[0051] In the present invention, the processed aluminum ash balls are added into the vertical reactor body 1 through the feed hopper 42, and they fall into the calcination hopper 2 and are stacked, and then are calcined in the vertical reactor body 1. During the calcination process, the motor 9 is started to drive the rotating shaft 5 to rotate, and then drive the multiple fan blades 6 to rotate, so that the external air is drawn into the vertical reactor body 1 through the air inlet 4, and then the air will flow from bottom to top, and the air will pass through the ventilation holes 3 to contact the aluminum ash balls, thereby playing a role in combustion.

[0052] During the calcination process, the rotation of the rotating shaft 5 will synchronously drive the ring gear 10 to rotate, drive the first gear 11 to rotate, and then drive the first rotating rod 7 to rotate, drive the stirring rod 8 to rotate, and stir the aluminum ash balls in the calcination bucket 2, so that the aluminum ash balls are turned over, and the surface of the aluminum ash balls can be fully in contact with the flame and air, thereby avoiding the stacking of aluminum ash balls, resulting in some parts of the aluminum ash balls being unable to contact the flame, and causing uneven calcination of the aluminum ash balls. In addition, since solid fluoride salts are produced on the surface of the aluminum ash balls during the calcination process, when the first rotating rod 7 and the stirring rod 8 rotate and collide with the surface of the aluminum ash balls, the solid fluoride salts produced on the surface of the aluminum ash balls due to calcination will be crushed and fall off.

[0053] The rotation of the first rotating rod 7 will drive the first reciprocating screw 21 to rotate, and drive the slider 19 to slide back and forth on the inner wall of the box body 12. The slider 19 will drive the sliding plug 13 to slide back and forth in a sealed manner through the cross bar 20, and then the external air will be drawn into the pump air cavity 132 through the one-way air inlet pipe 17, and then the air will be squeezed into the vertical groove 14 through the one-way air supply pipe 18, and finally the air will be ejected through multiple jet holes 15 and sprayed horizontally between the aluminum ash balls, thereby increasing the contact area between the aluminum ash balls and the air, and the calcination effect is better, and the injected air can further improve the cooling effect on the calcined aluminum ash balls.

[0054] In addition, the rotation of the first rotating rod 7 will drive the driving wheel 34 to rotate, and then drive the driven wheel 35 to rotate, drive the second reciprocating screw 33 to rotate, drive the rectangular block 29 to slide back and forth on the inner wall of the slide groove 28, drive the connecting rod 30 to move back and forth, and then drive the vertical rod 39 to move back and forth, drive the rack 40 to move back and forth, and then drive the second gear 38 to rotate forward and reversely, drive the second rotating rod 36 to rotate forward and reversely, and drive multiple knocking rods 37 to rotate forward and reversely, so that they continuously knock on the calcining bucket 2, causing the calcining bucket 2 to vibrate, and the vibration will be transmitted to the aluminum ash ball, causing the aluminum ash ball to vibrate, and the solid fluoride salt on the surface of the aluminum ash ball to vibrate, which makes it easier for the solid fluoride salt to fall off, and the fallen fluoride salt will flow upward with the air, and finally be discharged from the exhaust pipe 43, and discharged to the external collection equipment for collection and treatment.

[0055] Since the temperature of the aluminum ash balls needs to be maintained at about 1300 degrees Celsius during calcination, when the temperature in the vertical reactor body 1 is higher than 1300 degrees Celsius, the temperature sensor 41 will monitor and transmit a signal, and the solenoid valves on the inner walls of the one-way air inlet pipe 17 and the one-way air supply pipe 18 will be closed through the PLC control circuit, and the solenoid valves on the inner walls of the one-way air intake pipe 45 and the one-way exhaust pipe 46 will be opened. At this time, the air in the vertical reactor body 1 will be sucked into the vertical slot 14 through the multiple air injection holes 15, and then the air will enter the pump air cavity 132 through the one-way air intake pipe 45, and finally the air will be discharged through the one-way exhaust pipe 46, thereby extracting the air in the vertical reactor body 1, reducing the combustion medium, reducing the flame, and thus reducing The temperature inside the vertical reactor body 1, on the contrary, when the temperature inside the vertical reactor body 1 is lower than 1300 degrees Celsius, the temperature sensor 41 monitors and transmits a signal, and controls the electromagnetic valves on the inner walls of the one-way air inlet pipe 17 and the one-way air supply pipe 18 to open through the PLC control circuit, and controls the electromagnetic valves on the inner walls of the one-way air intake pipe 45 and the one-way exhaust pipe 46 to close. At this time, air will be pumped into the vertical groove 14, and the air will be sprayed into the vertical reactor body 1 through multiple jet holes 15, thereby increasing the combustion medium in the vertical reactor body 1, enhancing the calcination flame, and then increasing the temperature. Therefore, the temperature inside the vertical reactor body 1 can be automatically adjusted so that the temperature is always maintained at about 1300 degrees Celsius to ensure the calcination effect of the aluminum ash balls.

[0056] After all the aluminum ash balls are calcined, the solenoid valve on the inner wall of the discharge pipe 23 can be energized to open it, and the aluminum ash balls in the calcining bucket 2 will fall into the discharge pipe 23 and then be discharged through the discharge pipe 23. When the aluminum ash balls roll in the discharge pipe 23, due to the reciprocating sealing sliding of the sliding plug 13, the external coolant will be drawn into the pump liquid chamber 131 through the one-way liquid inlet pipe 25, and then the coolant in the pump liquid chamber 131 will be squeezed into the cooling pipe 24 through the one-way liquid supply pipe 26. The coolant will exchange heat with the aluminum ash balls, and then quickly cool down the aluminum ash balls that have just been calcined. There is no need to wait for them to cool down naturally or set up additional cooling equipment, thereby reducing production costs. Finally, the coolant will be discharged through the discharge pipe 27.

[0057] In addition, since the coolant in the cooling tube 24 often changes between hot and cold, scale may adhere to the inner wall of the cooling tube 24, thereby affecting the heat exchange of the coolant. Therefore, during the reciprocating sliding of the rectangular block 29, the vertical cylinder 31 will be driven to move back and forth through the connecting rod 30, and then the multiple extrusion heads 32 will move back and forth, continuously squeezing the cooling tube 24, causing the cooling tube 24 to bend and deform, and then the scale attached to the inner wall of the cooling tube 24 will be squeezed off, thereby improving the heat exchange effect of the coolant.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
