Description

TECHNICAL FIELD

[0002] In the recovery of waste palladium-carbon catalyst, the activated carbon carrier needs to be activated and pretreated to weaken the interaction between palladium and carbon, laying a foundation for the subsequent recovery of palladium. During the pretreatment process, active gas and carrier powder need to be introduced into the activation furnace for activation.

[0003] The existing activation furnace directly installs the heating component on the inner wall of the furnace body, causing the inner wall of the furnace body to be directly heated. Although the temperature can reach the level required for the activation of activated carbon, the heat is difficult to transfer to the center of the furnace body, causing the temperature at the center of the furnace body to be lower than that at the inner wall, and further causing uneven temperature distribution in the furnace. Moreover, the movement of the material in the furnace exacerbates the problem: it is lifted by the wall by the rotation of the furnace body, and then falls along the gravity, with a short contact time with the high-temperature inner wall, making it difficult to fully absorb heat, and only by prolonging the overall activation time can the quality be guaranteed. On the one hand, it leads to low processing efficiency, and on the other hand, part of the material may be in contact with the inner wall for a long time, in a high-temperature state, and over-activated, affecting the final quality.

[0020] Please see Figures 1 to 8 The image shows a palladium metal recovery device for waste palladium-carbon catalyst according to an embodiment of the present invention, comprising: a main body 10; a drum assembly 20 disposed on the main body 10, including a drum 21 and a first driving component 22, the first driving component 22 being used to drive the drum 21 to rotate; a transmission assembly 30 disposed on both sides of the drum assembly 20, the transmission assembly 30 being rotatably connected and communicating with both sides of the drum assembly 20, so that material enters or exits the drum assembly 20 through the transmission assembly 30; and a lifting assembly 40 disposed on the inner side of the drum 21, including a plurality of lifting members 41 circumferentially distributed around the axis of the drum 21 and heating members 42 disposed on the drum 21 and the lifting members 41; wherein, the lifting member 41 includes an arc portion 411 and a vertical portion 412 connecting the arc portion 411 and the drum 21, the opening of the arc portion 411 facing the outer side of the drum 21, and a first filter hole 413 provided at the end of the arc portion 411 away from the vertical portion 412 and not abutting against the inner wall of the drum 21. It can be understood that, through the main body 10 for accommodating the supporting roller assembly 20 to provide a running space, and through the conveying assembly 30, the material to be activated is transported into the roller 21 of the roller assembly 20 to roll with the roller assembly 20, and through the setting of the lifting assembly 40, the material is rolled into the lifting piece 41 at the bottom of the roller 21, and is wrapped to the top of the roller 21 under the limiting action of the vertical part 412 and the circular arc part 411 of the lifting piece 41, and in the process, the material rolls in the lifting piece 41 and is heated by the heating piece 42, so that a large amount of material is separated by the plurality of lifting pieces 41 for separate heating, thereby avoiding the problem that uneven heating causes some materials to need secondary activation, and as the material rolls in the lifting piece 41, the problem of over-activation caused by the difficulty of the outer material to roll to the inside when the material is too much to continuously contact the outside with a higher temperature is also avoided, and when the lifting piece 41 moves to the top of the roller 21, the material has been fully activated, and at this time, the circular arc part 411 is aligned with the axis of the roller 21 at the first filter hole 413, and the activated material can fall through the first filter hole 413 to the center of the roller 21, and then move with the gas sprayed by the conveying assembly 30 to the axis of the roller 21, thereby being transported out of the roller 21. Therefore, the present application solves the problem of lack of a high-efficiency and high-quality waste palladium carbon catalyst palladium metal recovery device in the prior art.

[0021] Specifically, the conveying assembly 30 includes an inlet cylinder 33 and an outlet cylinder arranged on both sides of the roller 21, and an air inlet cylinder, one end of the inlet cylinder 33 and the outlet cylinder is fixedly connected with the main body 10 and arranged outside the main body 10, and the other end is rotatably connected with the roller 21 and in communication, the side surface of the inlet cylinder 33 is provided with an inlet pipe 34, one end of the air inlet cylinder is arranged in the inlet cylinder 33 and in communication with the external gas supply device, and the other end is suspended in the roller 21. In specific implementation, the activated material enters the inlet cylinder 33 through the inlet pipe 34, and the activation gas is introduced through the air inlet cylinder to drive the activated material to move to the roller 21, so as to fall into the roller 21 and move with the lifting piece 41 in the roller 21 for activation. In addition, the inlet cylinder 33 and the outlet cylinder are fixedly connected with the main body 10, so that the roller 21 rotates alone, so that the feeding and discharging directions are controllable, the material is easy to enter and discharge, and the direction of the material is easy to control, so that the material is stable, thereby stably controlling the activation effect.

[0022] In addition, the drum 21 is provided with annular partitions 23, and the annular partitions 23 are arranged in parallel along the axis direction of the drum 21 to divide the drum 21 into a plurality of activation compartments. Each activation compartment is provided with a plurality of lifting pieces 41, and the air inlet cylinder is provided with a plurality of exhaust rings 35. At least one exhaust ring 35 is arranged in each activation compartment. In specific implementation, the drum 21 is divided into a plurality of activation compartments by arranging a plurality of annular partitions 23. After the material is activated in the previous activation compartment, the material falls into the center of the drum 21 and moves to the next activation compartment under the action of the gas flow channel, and the activation step is repeated again, so that the function of multiple activation is realized by a single device. In addition, the activation of the material is segmented by a plurality of activation spaces, so that the material in the single lifting piece 41 of the single activation compartment is relatively less, and the uniformity of the temperature is better. Through multiple activation steps, the activation effect is more controllable than single long-time activation, so that the activation effect is better, and the material is transported in one device only, without consuming more time. In addition, the material is tumbled and stirred when it is transported between different compartments, so that the material can be further prevented from moving to the inside and being heated for a long time in the relatively high-temperature area, thereby ensuring the activation effect. In addition, when the material is transported between different activation compartments, the material moves to the bottom or other areas of the next compartment. In other areas such as the middle part, the material is moved to the next compartment under the action of the gas flow. In the top part, the activation time in the compartment is insufficient, which leads to uncontrollable overall activation effect. Therefore, in order to avoid the above-mentioned situation, the flow direction of the gas is controlled, so that the gas is injected in the obliquely downward direction, thereby ensuring that the material moves to the bottom of the next compartment. Or the air injection piece is arranged below the axis of the drum 21, so that the material moves to the lower half area of the drum 21, and then moves to the next compartment under the action of the gas flow, thereby moving to the bottom of the next compartment in a parabolic trajectory.

[0023] Specifically, the lifting piece 41 close to the feeding cylinder 33 is provided with a turnover component 43, the turnover component 43 includes a turnover plate 431 and a first driving motor 432, the first filter hole 413 is arranged on the turnover plate 431, the first driving motor 432 is used for driving the turnover plate 431 to rotate relative to the lifting piece 41, and the lifting piece 41 is provided with a groove 414 to cover the first filter hole 413. In specific implementation, since the material is in a granular state, the material is prone to agglomeration when it enters the drum 21 for activation, so that the activated material is difficult to pass through the first filter hole 413. Therefore, the turnover component 43 is arranged in the previous activation compartment, so that the agglomerated material after activation can fall from the lifting piece 41 through the groove 414, and the material not fully activated in the agglomeration is activated after being scattered by collision at the bottom of the drum 21.

[0024] In addition, the activation compartment close to the feeding cylinder 33 is provided with a vibrating component 50, which includes a first arc-shaped plate 51 and a second driving component 52 for driving the first arc-shaped plate 51 to vibrate up and down. The first arc-shaped plate 51 is located directly above the air inlet cylinder and opens vertically upward. The bottom of the first arc-shaped plate 51 is provided with a second filter hole 53. In specific implementation, in order to avoid that the agglomerated material drives the activated material outside to move to the bottom and be over-activated again. The vibrating component 50 is further provided to make the agglomerated material vibrate on the first arc-shaped plate 51, so that the activated material outside the agglomerated material falls off and is transported to the next compartment through the second filter hole 53.

[0025] Specifically, the vibrating component 50 further includes a second arc-shaped plate 54 and a second driving motor 55. One end of the second arc-shaped plate 54 is rotationally connected with the first arc-shaped plate 51, the other end abuts against the annular partition plate 23 and the bottom is provided with a third filter hole 56. The second driving motor 55 is used to drive the first arc-shaped plate 51 to rotate towards the second arc-shaped plate 54, so that the material on the first arc-shaped plate 51 is transferred to the second arc-shaped plate 54. The second driving component 52 is connected with the bottom of the second arc-shaped plate 54. In specific implementation, in order to avoid that the agglomerated material directly falls to the bottom of the roller 21 and scatters, causing the unactivated material to move to the next compartment. The second arc-shaped plate 54 is further provided to make the agglomerated material vibrate on the first arc-shaped plate 51 to shake off the activated particles outside, and then be transported to the second arc-shaped plate 54 and vibrate on the second arc-shaped plate 54, so that the agglomerated material is scattered into particles and then falls from the vibrating component 50 through the third filter hole 56. By reasonably setting the inclination direction and position of the second arc-shaped plate 54, the third filter hole 56 is away from the axis of the roller 21 and located in the lower half region of the roller 21, so that the material falling from the third filter hole 56 will not move to the next compartment under the action of the air flow and fall into the lifting member 41 in the target position. Reasonably control the activation time to ensure that the activation effect is controllable.

[0026] Further, the third filter hole 56 of the second arc-shaped plate 54 is provided with a crushing needle 57. In specific implementation, simple vibration cannot efficiently disperse the agglomerated material, so that the crushing needle 57 is provided to cooperate with the crushing needle 57 to crush and disperse the agglomerated material when vibrating, thereby improving the dispersion efficiency of the agglomerated material and ensuring the efficiency of the whole process.

[0027] In addition, the first arc-shaped plate 51 is provided with a protruding portion 511 on the side close to the second arc-shaped plate 54, and is provided with an elastic clamping layer 512. In addition, due to the difficulty in accurately controlling the size and density of the agglomerated material, and the fact that the agglomerated material with large size and loose is directly dropped into the first arc-shaped plate 51, the collision force is too large, which causes the agglomerated material to directly scatter, and the unactivated material particles in the agglomerated material also fall through the second filter hole 53 and then move to the next compartment under the action of the airflow. The elastic clamping layer 512 is used to ensure that the material will not scatter at the first arc-shaped plate 51 due to collision. In addition, by providing the protruding portion 511, the agglomerated material is prevented from directly rushing out of the first arc-shaped plate 51 under the kinetic energy of the falling motion, colliding with the bottom of the drum 21 and scattering, so that the unactivated particles on the inner wall of the agglomerated material move to the next compartment under the action of the airflow.

[0028] Specifically, the first arc-shaped plate 51 and the second arc-shaped plate 54 are provided with baffle plates 58 on both sides, and the second arc-shaped plate 54 is provided with a cover plate 59 covering the third filter hole 56 on the end away from the first arc-shaped plate 51. In specific implementation, the agglomerated material rolls and vibrates on the first arc-shaped plate 51 and the second arc-shaped plate 54, and the material after shaking off will not fall through the second filter hole 53 or the third filter hole 56 at first time, so that the material after shaking off has the risk of falling from both sides of the first arc-shaped plate 51 and the second arc-shaped plate 54, and the whole agglomerated material has the risk of falling from both sides. Therefore, the baffle plates 58 are arranged to hinder the movement to avoid this situation. In addition, the cover plate 59 is arranged on the second arc-shaped plate 54 to prevent the scattered material from flying out from the top of the second arc-shaped plate 54 when the agglomerated material is broken and collided, causing the unactivated material to move to the next compartment and resulting in poor activation effect.

[0029] In addition, the first driving component 22 includes a transmission shaft 221, a gear 222 arranged on the transmission shaft 221, and a fourth driving motor 223 connected with the transmission shaft 221, and the outer side of the drum 21 is provided with a tooth ring 24 matched with the gear 222. In specific implementation, the drum 21 is mainly supported by the transmission assembly 30, and the fourth driving motor 223 drives the transmission shaft 221 to rotate, and the transmission shaft 221 drives the plurality of gears 222 arranged thereon to rotate, and the gears 222 cooperate with the tooth ring 24 on the drum 21 to drive the drum 21 to rotate. In addition, by arranging a plurality of gears 222 and tooth rings 24, the rotation trend of the drum 21 is evenly distributed, and the rotation of the drum 21 is more stable, so as to ensure the stable control of the activation process. In addition, in specific implementation, the bottom of the main body 10 is also provided with a support frame, so that the waste palladium carbon catalyst palladium metal recovery device can be stably installed at the required position, and the waste palladium carbon catalyst palladium metal recovery device can be stably operated by the heat dissipation openings arranged on both sides of the main body 10.

[0030] In summary, the application provides a running space by the main body 10 for accommodating the supporting roller assembly 20, and transports the material to be activated into the roller 21 of the roller assembly 20 by the conveying assembly 30 to roll with the roller assembly 20, and the material is rolled into the lifting piece 41 at the bottom of the roller 21, and is wrapped to the top of the roller 21 by the limiting action of the vertical part 412 and the circular arc part 411 of the lifting piece 41, and moves in the lifting piece 41, and the material rolls in the lifting piece 41 and is heated by the heating piece 42, so that a large amount of material is separated by the plurality of lifting pieces 41 to be heated separately, thereby avoiding the problem that uneven heating causes some material to need secondary activation, and as the material rolls in the lifting piece 41, the problem that when the material is too much, the outside material is difficult to roll to the inside to continuously contact the outside with a higher temperature, thereby causing over-activation, is also avoided, and when the lifting piece 41 moves to the top of the roller 21, the material has been fully activated, and at this time, the circular arc part 411 is aligned with the first filter hole 413 towards the axis of the roller 21, and the activated material can fall through the first filter hole 413 to the center of the roller 21, and then moves with the gas sprayed by the conveying assembly 30 to the axis of the roller 21, thereby being transported out of the roller 21. Therefore, the application solves the problem of lacking a high-efficiency and high-quality waste palladium carbon catalyst palladium metal recovery device in the prior art.
