[0002] In the process of extracting nickel from waste acid waste, the quality and composition of the waste acid waste may vary greatly. This means that the amount of acid solution added and the reaction conditions, such as temperature and stirring speed, need to be adjusted according to the specific conditions of the waste acid waste during the extraction process. In addition, during the mixing reaction of the acid solution and the waste acid waste, harmful waste gases, such as sulfur dioxide, may be generated, which not only pollute the environment but also pose a threat to human health.

[0038] A device for extracting nickel products from waste acid and waste, the working principle is as follows: S1; the crushed waste material to be mixed is added into the reaction bin 1 through the feed funnel 102 at the top of the reaction bin 1 (the second solenoid valve is in a closed state at this time). As the material enters, the total mass of the reaction bin 1 changes, causing it to move downward. During this process, the first compression spring 104 is compressed through the connecting plate 103, and the first double-sided rack 5 is driven to move downward synchronously through the cross plate 101; S2; the first double-sided rack 5 is synchronously driven with 905b to move the first gear 701, the fifth gear 901 rotates and the contact piece on the sliding rheostat 6 moves: In this rotation direction, under the control of the transmission direction of the first ratchet assembly a720A and the first ratchet assembly b720B, the second gear 702 is driven by the synchronous belt 905b, but the first bevel gear 712 is not driven, and the second gear 702 drives the second double-sided rack 703 to move upward and compress the reset spring 704; The movement synchronous belt 905b of the second double-sided rack 703 drives the third gear 801 to rotate, and under the cooperation of the overload mechanism 808, the rotating rod 802 rotates synchronously, driving the fourth gear 803 to rotate, and the fourth gear 803 drives the driven rack 804 to move away from the vertical rod 805. When the driven rack 804 moves to contact one end of the limit slide bar 811 and cannot move again, the excess force is unloaded by the overload mechanism 808; Similarly, in this rotation direction, under the control of the transmission direction of the second ratchet assembly a908A and the second ratchet assembly b908B, the intermediate block 907 is driven, but the synchronous block 906e is not driven, the intermediate block 907 drives the transmission mechanism 906 to rotate, drives the transmission member 903 installed at the center of the coil spring 902 to rotate, and drives the coil spring 902 to perform a winding and force storage movement; S3; when the material addition is completed, the reaction chamber 1 no longer moves downward, the reset spring 704 and the coil spring 902 are no longer under force, and the contacts on the rheostat stop moving synchronously: Feedback is sent to the PLC controller by the sliding rheostat 6, which receives and processes the information, then closes the first solenoid valve, starts and adjusts the appropriate output speed of the motor 2, starts and adjusts the output of the electric heating tube 3, and confirms the reaction time (Note: this command is only triggered when the contact piece on the sliding rheostat 6 is completely still. When the PLC controller detects that the contact piece is still moving, it will not issue the command); The second double-sided rack 703 is driven by the return spring 704 to move in the reverse direction. At this time, since the rotation direction is opposite to that of the above S2: The third gear 801 is driven to rotate in the opposite direction, and with the cooperation of the overload mechanism 808, the rotating rod 802 is driven to rotate the fourth gear 803, and the driven rack 804 is driven to move toward the vertical rod 805, pressing the trigger switch, and sending a signal to the PLC controller to change the damping value of the magnetorheological fluid damper 806, and cooperate with the connecting plate 103 to prevent the reaction chamber 1 from moving downward; The first bevel gear 712 is driven, but the first gear 701 does not rotate. The first bevel gear 712 drives the second bevel gear 713 to rotate, and the second bevel gear 713 drives the transmission rod 714. The transmission rod 714 drives the local gear 706 to rotate. The local gear 706 cooperates with the teeth in the straight groove part to drive the straight groove part to reciprocate. The straight groove part drives the installation rod 708 and the piston 707 to reciprocate in the transmission cylinder, generating a pressure difference, and cooperates with the input pipe 719 and the output pipe 709a to transport the acid solution in the liquid storage tank 718 to the connecting pipe 711, and then add it to the reaction tank 1; The coil spring 902 drives the transmission member 903 to rotate in reverse, drives the synchronous block 906e to move, but does not drive the middle block 907 to move. The synchronous block 906e drives the fourth bevel gear 906d, drives the third bevel gear 906c meshing therewith to rotate, the third bevel gear 906c drives the cylindrical rod 906a to rotate, the cylindrical rod 906a drives the fifth bevel gear 906f to rotate, drives the sixth bevel gear 906g meshing therewith to rotate, drives the synchronous rod 906i to rotate, the synchronous rod 906i drives the seventh bevel gear 906j to rotate, and the seventh bevel gear 906j drives the eighth bevel gear 906k meshing therewith, drives the centrifugal blade 910 to rotate, generates centrifugal force, exhausts the reaction chamber 1, and purifies it through the activated carbon treatment sheet; S4; After the reaction is completed, the PLC controller stops the motor 2 and the electric heating tube 3, opens the first solenoid valve and the second solenoid valve, and connects the magnetorheological fluid damper 806 to the current to change it to the initial state, unloads the material and restores the device to the initial setting state.
