Description

Technical Field

[0002] Extracting, separating and recovering precious metal palladium from waste catalysts can improve the utilization rate of palladium resources. When extracting palladium, the waste catalyst needs to be pretreated. In the prior art, in the equipment and method for extracting and separating precious metal palladium from waste catalysts with the published application number 202410160883.6, the crushing, screening and leaching and dissolving equipment are integrated into one equipment, which eliminates the process of material transfer, simplifies the process flow, and improves production efficiency. However, the material after fine screening is not quantified and transported. As the material continues to enter the leaching device, the required amount of acidic solution continues to increase. However, the equipment cannot determine the amount of material entering, and correspondingly, the amount of acidic solution that needs to be input cannot be determined. When the material is relatively more acidic, the leaching reaction of the material is insufficient. When the material is relatively less acidic, part of the acid does not participate in the reaction, resulting in a waste of acid when the palladium-containing solution after the transfer reaction.

[0034] Working principle: the material is thrown in through the top of the processing box 1, and the passing material is crushed by two sets of crushing rollers 3. The crushed material falls to the top of the screen plate 41, and is screened by the vibration motor 410 and the screen plate 41. The material passing through the screen plate 41 falls to the top of the quantitative plate 52 and is monitored by the primary pressure sensor 53. When the weight of the material on the top of the quantitative plate 52 reaches a preset value, the primary pressure sensor 53 transmits the data to the peripheral terminal, and the peripheral terminal controls the three-stage drive motor 54 to start. The three-stage drive motor 54 drives the transmission shaft 55 to rotate 90°, so that the flap 51 changes from a vertical state to a horizontal state, which has a shielding effect and prevents the screened material from falling to the top of the quantitative plate 52. After the transmission shaft 55 rotates 90°, the three-stage drive motor 54 drives the transmission shaft 55 to rotate 90°. The four-stage drive motor 54 transmits a signal to the peripheral terminal, the peripheral terminal receives the signal, and the electric telescopic rod 511 is turned on. The longitudinal plate 510 is pulled up through the output end at the bottom of the electric telescopic rod 511, thereby driving the baffle 57 to rise through the transverse plate 59. Under the action of the secondary vertical groove 518 and the tertiary vertical groove 519, the baffle 57 will not affect each other with the four-stage drive screw rod 514 and the four-stage stabilizing rod 515. After the top surface of the transverse plate 59 contacts the processing box 1, the transverse plate 59 cannot continue to rise, the electric telescopic rod 511 senses, and transmits a signal to the external terminal. The external terminal receives the signal and controls the four-stage drive motor 513 to turn on. The four-stage drive motor 513 drives the four-stage drive screw rod 514 to rotate. The opposite threads on the left and right outer walls of the driving screw 514 cause the two groups of four-stage push plates 516 to move in opposite directions until the outwardly extending plate 517 pushes the material through the four-stage opening 56 into the material guide frame 520, and the material falls into the leaching box 64 through the central frame 521, the feeding frame 610, and the feeding port 69. After the material on the top of the quantitative plate 52 is cleared, the primary pressure sensor 53 transmits data to the peripheral terminal, which receives the data and controls the four-stage driving motor 513 to drive the four-stage driving screw 514 to reverse, until the two groups of four-stage pushing plates 516 fit together and cannot move further, and the four-stage driving motor 513 cannot drive the four-stage driving screw 514 to rotate, and the four-stage driving motor 513 transmits the signal to the peripheral terminal, which receives the signal and controls the four-stage driving The motor 513 is turned off, and the weight of the material falling in the leaching box 64 is monitored through the secondary pressure sensor 63. After the material has fallen, the weight of the material reaches the preset value of the secondary pressure sensor 63, and the secondary pressure sensor 63 transmits the data to the external terminal. The external terminal receives the data and controls the primary drive motor 61 to start. The output shaft at the top of the primary drive motor 61 drives the rotating plate 62 to rotate 90°, so that another group of leaching boxes 64 with acidic solution pre-set are moved to the bottom of the centralized frame 521, and the switching of the leaching boxes 64 is completed. The setting of the arc plate 612 and the blocking vertical plate 611 can block the feed port 69 to prevent the inner cavity of the leaching box 64 from being connected to the external environment, thereby affecting the reaction between the material and the acidic solution; Larger materials cannot pass through the sieve plate 41. When a large amount of materials are piled up, the material is observed through the observation window on the front side of the processing box 1, the rotation of the crushing roller 3 is suspended, the secondary drive motor 42 is turned on, and the secondary drive screw 43 is driven to rotate, thereby driving the secondary push plate 45 to move left. The secondary push plate 45 on the left side is separated from the processing box 1 through the secondary opening 47. The materials between the two groups of secondary push plates 45 are pushed out of the secondary opening 47 and fall into the receiving box 48, completing the unqualified material discharge, and contacting the processing box 1 on the left side of the limiting plate 49. Afterwards, the movement of the limiting plate 49 is blocked, and the secondary driving screw 43 cannot rotate. The secondary driving motor 42 transmits a signal to the external terminal, and the external terminal receives the signal and controls the secondary driving motor 42 to drive the secondary driving screw 43 to rotate in the opposite direction until the right side of the limiting plate 49 contacts the processing box 1. The movement of the limiting plate 49 is blocked, and the secondary driving screw 43 cannot rotate. The secondary driving motor 42 transmits a signal to the external terminal, and the external terminal controls the secondary driving motor 42 to shut down, so that the unqualified materials can be exported in a short time.
