[0030] The inner cavity of the rack 25 is provided at the top with a screw rod fixing piece 15 through a threaded connection, and the screw rod fixing piece 15 is connected with the upper and lower lifting screws 14 through a double-nut locking mode. The contact surface of the screw rod fixing piece 15 with the lifting guide rail is provided with an adjusting gasket set, which can realize an axial fine adjustment of ±2 mm. The screw rod fixing piece 15 is embedded with an angular contact ball bearing inside, and the outer ring is provided with an oil seal sealing structure.

[0031] The inner cavity of the rack 25 is provided at the top and the bottom with a limiting device 18 through a bolt, and the limiting device 18 comprises an SMC type air cylinder. The output end of the air cylinder is provided with a C-shaped ring through a threaded connection. The opening of the C-shaped ring is provided with a proximity switch, which can realize position signal feedback. The inner wall of the C-shaped ring is bonded with a polyurethane buffer pad, and the maximum buffer stroke is 15 mm.

[0032] The inner cavity of the reaction kettle feeding port 24 is provided at both sides with a sliding rod 17 through a sliding rod fixing piece 19, and the sliding rod 17 is inserted into a linear bearing outside the upper and lower lifting nuts 11. The linear bearing is embedded with a graphite self-lubricating bushing, and the maintenance-free period reaches 5000 hours. The surface of the sliding rod 17 is subjected to high-frequency quenching treatment, and the hardness reaches HRC58-62.

[0033] The outer part of the rack 25 is assembled with reinforcing ribs by welding, and the bottom corners of the rack 25 are uniformly assembled with Foma wheel type universal wheels. The universal wheels are provided with self-locking pedal mechanisms, and the single-wheel bearing capacity reaches 500 kg.

[0034] The outer parts of the waste gas outlet 20, the acid adding port 21 and the water spraying inlet 22 are all assembled with pneumatic control valves, and the outer parts of the waste gas outlet 20, the acid adding port 21 and the water spraying inlet 22 are welded with neck butt flanges. The flanges meet the HG / T 20592 standard and are matched with metal winding gaskets. The sealing surface of the flange adopts an RF protrusion structure and is used in combination with a winding gasket.

[0035] The outer part of the stirring motor 8 is assembled with a motor rack through bolts, and the motor rack is assembled on the top of the stirring motor fixing rack 13 through a shock-absorbing rubber pad. The hardness of the shock-absorbing rubber pad is 55±5°, and the compression permanent deformation rate is ≤15%. The motor rack adopts an aluminum alloy profile frame structure, and the surface is anodized.

[0036] The outer part of the heating heating rod 9 is connected and assembled with a PID control module through wires, and the heating heating rod 9 is sleeved with a brass heat conduction sleeve near the outer part of the dissolving tank 6. The PID control module has an RS485 communication interface, can be connected to a DCS control system, and supports the Modbus RTU protocol.

[0037] The top of the reaction kettle container 23 is assembled with a waste gas treatment device through a flange, and the top of the waste gas treatment device is assembled with an activated carbon filter element through a clamp. The waste gas treatment device is provided with three filter layers, including a primary filter screen, a HEPA filter screen and an activated carbon adsorption layer, and the acid gas removal rate reaches 99.5%.

[0038] In the initial state adjustment stage of the equipment, the operator completes the equipment positioning through the Foma wheel type universal wheels on the outer part of the rack 25 and enables the self-locking pedal mechanism. At this time, the driving motor 1 is in standby state, and its variable frequency speed regulation characteristic allows subsequent adjustment of the speed according to the load demand. Before starting, the initial position of the ultrasonic liquid level meter 26 needs to be confirmed. This component ensures the vertical guiding accuracy of the 14 up-down lead screw through a four-column cylindrical roller bearing structure, and the hard oxidation surface treatment layer has an oxidation film thickness ≥30μm to effectively resist the corrosion of the heat conducting oil medium. The screw fixing piece 15 is connected with the lifting screw through a double nut locking mechanism, the built-in angular contact ball bearing bears the axial load, and the adjustment gasket set is used to realize the axial alignment compensation of ±2mm.

[0039] In the material loading link, the operator puts the metal raw material into the reactor through the reactor inlet 24 of the reactor container 23, and the inner wall of the inlet is coated with Teflon to prevent material adhesion. At this time, the sliding rod 17 forms a kinematic pair with the upper and lower lifting nuts 11 through the linear bearing, and the graphite self-lubricating bushing ensures a 5000-hour maintenance-free period. After the raw material is loaded, the dissolving tank 6 is driven to move downward along the lifting screw 14, and its movement trajectory is guided by the sliding seat plate 12 and the sliding sleeve assembly 16. The O-shaped sealing ring and the copper-based wear-resistant sheet form a double-sealing structure, and the protection level reaches IP67. When the dissolving tank 6 contacts the reactor container 23, the SMC cylinder of the 18 limiting device drives the C-shaped ring to implement mechanical limiting, and the polyurethane buffer pad absorbs impact energy. The proximity switch sends a feedback signal to the control system.

[0040] The dissolving process execution stage includes multi-parameter collaborative control: 9 U-shaped heating heating rods implement indirect heating through modified alkyl benzene type heat conducting oil, and the highest use temperature of the medium is 320℃, which realizes ±1℃ temperature control accuracy through the cooperation of the PID control module. The magnetic liquid level meter interface of the heating layer drain valve 3 monitors the heat conducting oil level in real time, and the thermal conductivity coefficient of the perlite insulation material in the double-layer jacket structure is ≤0.08 W / m·K, reducing heat loss. At the same time, the stirring motor 8 generates an axial flow field through the three-blade propeller 5 generated by the stirring paddle 5, and the blade sawtooth-shaped shear edge breaks the metal surface oxide layer at a speed of 150-300 rpm. The stirring torque is amplified through the three-stage planetary gear set of the transmission reduction box 2, and the design of the reduction ratio 1:30 makes the output torque reach 4500 N·m. The torque limiter sets the overload protection threshold of 150 N·m, which automatically cuts off the power transmission when encountering metal foreign matter.

[0041] The chemical dosing system adopts a staged control strategy: 21 acid inlet quantitatively injects the reaction medium through a pneumatic control valve, and the neck welding flange plate HG / T 20592 standard ensures the sealing reliability of the interface. Acidic waste gas generated by the reaction is discharged through the 20 waste gas outlet, and the built-in DN50 stainless steel mesh demister removes more than 95% of liquid droplets. The supporting waste gas treatment device realizes a 99.5% acid gas removal rate through a three-stage filter layer of primary filter screen + HEPA filter screen + activated carbon adsorption layer. The spray inlet 22 starts the 7 annular cleaning spray pipe after the dissolution is completed, and the 12 fan-shaped nozzles cover the tank wall at an angle of 120°. The spray pressure is stabilized at 0.3 MPa through the PID control system.

[0042] In the device security protection layer, the nickel-based alloy corrosion-resistant layer of the sliding seat plate 12 resists acid mist corrosion, and the 5mm thick 316L stainless steel inner layer of the dissolving tank 6 and the carbon steel plastic sprayed outer layer form a double corrosion-resistant barrier. The lifting mechanism adopts a self-locking trapezoidal thread pair with a tooth angle of 60° and a gap of 0.05-0.1mm, and the hard chromium wear-resistant layer makes the screw surface hardness reach HV850 or more. When the device encounters abnormal vibration, the shock-absorbing rubber pad of the stirring motor fixing frame 13 with a Shore hardness of 55±5° can absorb more than 30% of the impact energy, and the aluminum alloy profile frame is connected by bolts to maintain structural rigidity.

[0043] The drainage stage adopts a hierarchical control mode: the heating layer drainage valve 3 preferentially discharges the heat transfer oil medium, and the pneumatic ball valve structure with a maximum pressure of 1.6MPa ensures the safe discharge of high-temperature medium; the dissolving tank dissolving layer drainage valve 4 is started after the liquid level sensor confirms that the tank body is empty, and the polytetrafluoroethylene valve seat resists strong acid corrosion. In the entire process, the HMI module 27 Pt100 platinum resistance monitors the key point temperature with an accuracy of 0.1℃, and the edge computing controller 28 prevents the sensor probe from being damaged by metal debris.

[0044] During the device maintenance stage, the oil seal structure of the screw fixing part 15 prevents the leakage of lubricating grease, and the hard oxide layer of the lifting guide rail facilitates the removal of metal debris. The surface of the slide rod 17 treated by high-frequency quenching has a hardness of HRC58-62 and can withstand long-term reciprocating wear, and the graphite self-lubricating bushing maintains a fitting gap of 0.1mm or less within 5000 hours. When the device needs to be transferred, the shell reinforcement structure ensures the overall rigidity.

[0045] The device realizes the automation and safety of metal dissolution process through the deep integration of mechanical transmission, thermal control, and chemical addition systems. Each structural module forms a closed-loop control in key links such as vertical lifting, stirring and shearing, temperature regulation, and medium conveying, ensuring efficient and environmentally friendly dissolution of metal materials in a closed environment.

[0046] The metal dissolution device adopts a vertical lifting mechanism instead of the traditional multi-layer frame design. The precise cooperation between the upper and lower lifting screws and nuts enables the stirring system to adjust the height in a single axial direction, reducing the dependence on vertical space in the factory building. By abandoning the complex pumping system and directly connecting the reaction kettle 23 and the dissolving tank 6, the material transfer relies entirely on gravity, fundamentally eliminating safety hazards such as pipe leakage and pressure fluctuations.

[0047] Under the premise of ensuring operational safety, the integrated heating device and temperature control medium achieve precise control of the reaction temperature. The synergy of the stirring system and the heating assembly enhances the mass transfer efficiency during metal dissolution, and the partitioned feeding port and drainage valve adapt to the multi-stage process requirements.

[0048] The cleaning spray device arranged at the top of the inner cavity can realize rapid online flushing, combined with the open structure of the reaction kettle container 23, greatly simplifying the daily maintenance process. The integrated design of the exhaust gas discharge channel ensures that the reaction gas is directly discharged for treatment, avoiding the accumulation of harmful substances, while the use of the heating medium 10 optimizes energy utilization efficiency, and the overall structure is integrated through components and process simplification, effectively reducing manufacturing and operating costs while ensuring equipment performance.
