Description

Technical Field

[0001] This utility model relates to the field of liquid addition device technology, and in particular to a copper melting liquid addition device. Background Technology

[0002] A copper smelting solution adding device is an automated liquid delivery system specifically designed for copper smelting processes in industrial production. It is primarily used to precisely and stably add copper smelting solution to containers such as copper smelting tanks and reaction vessels to ensure the continuous and efficient copper smelting reaction. Its core components typically include a storage tank for storing the copper smelting solution, a piping system for liquid delivery, metering components (such as metering pumps and flow valves) for controlling the addition volume and rate, and a control unit (such as sensors and PLC controllers) for automated operation. In fields such as electronics manufacturing and printed circuit board (PCB) production, the copper smelting process is a crucial step in forming conductive circuits, requiring strict control of the concentration and amount of copper smelting solution added. The copper smelting solution adding device, by setting adding parameters, can replace manual operation to achieve quantitative and timed addition of the solution.

[0003] Currently available copper smelting solution dosing devices have significant shortcomings in structural design and ease of use, particularly in the maintenance and replacement of the storage tank. Existing devices often use PVC for the storage tank to withstand the corrosiveness of the copper smelting solution, but this material has limited strength and is prone to cracking and aging after prolonged use due to corrosion from the solution, temperature changes, or external impacts. Furthermore, the connection between the storage tank and the piping and pump body relies heavily on complex flange, bolt, or specialized clamp structures. To ensure sealing, multiple layers of sealing rings and sealant are often used at the connection points. This results in a cumbersome and time-consuming disassembly process after storage tank damage, requiring the removal of each fixing component and cleaning of residual sealing material. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a copper melting solution adding device to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a copper smelting liquid adding device, including a frame, a base plate fixedly connected inside the frame, two symmetrically arranged hydraulic cylinders fixedly connected to the top surface of the base plate, a bearing plate slidably connected to the output end of the two hydraulic cylinders, a limit ring fixedly connected to the top surface of the bearing plate, a liquid storage cylinder slidably connected to the inner wall of the limit ring, a locking ring fixedly connected to the outer surface of the liquid storage cylinder and fitting against the top of the limit ring, the locking ring being connected to the limit ring by bolts, a stirring element rotatably connected inside the liquid storage cylinder via a bearing, a spline sleeve fixedly connected to the top of the stirring element, a motor fixedly connected to the top of the frame, and a spline shaft slidably connected to the spline sleeve fixedly connected to the output end of the motor.

[0007] Preferably, in any of the above embodiments, a water pump is fixedly connected to one side of the frame, a connecting pipe is fixedly connected to the input end of the water pump, and the end of the connecting pipe away from the water pump is connected to the liquid storage tank through a flange.

[0008] Preferably, in any of the above solutions, the top surface of the support plate is fixedly connected to two symmetrically arranged pins, and the liquid storage cylinder is engaged with the support plate through the pins.

[0009] Preferably, in any of the above embodiments, the inner wall of the frame is fixedly connected to two symmetrically arranged baffles, and a guide rod is fixedly connected between the baffles and the frame, and the bearing plate is slidably connected to the guide rod.

[0010] Preferably, one side of the blocking plate is rotatably connected to a locking bolt, and the threaded part of the locking bolt is threadedly connected to the bearing plate.

[0011] Preferably, of any of the above solutions, an electrical control box is fixedly connected to one side of the frame, and the motor and water pump are both electrically connected to the electrical control box.

[0012] Preferably, in any of the above embodiments, the top surface of the base plate is fixedly connected to two symmetrically arranged top plates by a vertically arranged support rod, and two clearance grooves adapted to the top plates are opened through one side of the limiting ring, with the two clearance grooves corresponding to the two top plates respectively.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When the liquid storage tank needs to be replaced, first remove the flange bolts between the connecting pipe and the liquid storage tank to separate the pipeline; loosen the bolts connecting the locking ring and the limit ring, then start the hydraulic cylinder to drive the bearing plate to move downward along the guide rod until the spline shaft disengages from the spline sleeve; continue to control the hydraulic cylinder to descend, allowing the bearing plate to move the liquid storage tank downward, so that the top plate on the bottom plate passes through the clearance groove of the limit ring, gradually pushing the liquid storage tank out of the limit ring, while the liquid storage tank disengages from the pin engagement, finally completing the disassembly of the liquid storage tank; when installing a new liquid storage tank, reverse the operation so that the top plate assists in lifting the liquid storage tank into the limit ring, and after positioning by the pin engagement, tighten the bolts of the locking ring, then raise the hydraulic cylinder to connect the spline shaft with the spline sleeve, and finally connect the flange to complete the pipeline installation. The automatic ejection and insertion of the liquid storage tank is achieved by the cooperation of the top plate and the clearance groove, using the lifting of the hydraulic cylinder, replacing the laborious operation of manual lifting; the detachable design of flange connection and bolt fixation makes the separation of pipeline and liquid storage tank easier, avoiding the cumbersome disassembly of traditional complex connection structures; the snap-fit ​​of the pin shaft and the sliding fit of the spline bushing ensure accurate positioning when replacing the liquid storage tank, greatly simplifying the maintenance process and reducing the difficulty of operation.

[0014] 2. During operation, the motor drives the agitator to rotate via the splined shaft and splined sleeve, agitating the copper-plated liquid in the storage tank. When the hydraulic cylinder raises and lowers the support plate, the guide rod ensures smooth movement and prevents the storage tank from shaking. Once the storage tank reaches the designated position, the locking bolts on the blocking plate are tightened to secure it to the support plate via threaded connection. The electrical control box synchronously regulates the operation of the motor and water pump, ensuring coordinated agitation and liquid addition. The sliding connection between the splined shaft and splined sleeve ensures power transmission without affecting the raising and lowering of the storage tank. Continuous agitation by the agitator prevents the copper-plated liquid from settling. The cooperation between the guide rod and the locking bolts prevents accidental movement of the support plate and ensures stable connection between the storage tank and other components. The centralized control of the electrical control box improves operational convenience. The top plate provides support when the storage tank descends, sharing the pressure on the support plate, extending the service life of the device, and enhancing overall operational stability and safety.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0018] like Figures 1 to 5 As shown, a copper smelting liquid adding device includes a frame 1. A base plate 2 is fixedly connected inside the frame 1. Two symmetrically arranged hydraulic cylinders 3 are fixedly connected to the top surface of the base plate 2.

A limit ring 5 is fixedly connected to the top surface of the bearing plate 4. A liquid storage cylinder 6 is slidably connected to the inner wall of the limit ring 5. A locking ring 7 that fits against the top of the limit ring 5 is fixedly connected to the outer surface of the liquid storage cylinder 6. The locking ring 7 is connected to the limit ring 5 by bolts. An agitator 8 is rotatably connected inside the liquid storage cylinder 6 through a bearing. A spline sleeve 9 is fixedly connected to the top of the agitator 8. A motor 20 is fixedly connected to the top of the frame 1. A spline shaft 10 that is slidably connected to the spline sleeve 9 is fixedly connected to the output end of the motor 20.

[0019] As an optional technical solution of this utility model, a water pump 11 is fixedly connected to one side of the frame 1, and a connecting pipe 12 is fixedly connected to the input end of the water pump 11. The end of the connecting pipe 12 away from the water pump 11 is connected to the liquid storage tank 6 through a flange. The water pump 11 on one side of the frame 1 is connected to the flange of the liquid storage tank 6 through the connecting pipe 12. This can not only stably draw copper-plating liquid from the liquid storage tank 6 to realize the liquid addition function, but also ensure the pipeline is sealed through the flange connection to prevent copper-plating liquid leakage. At the same time, the flange connection is easy to disassemble, providing convenience for the replacement of the liquid storage tank 6 or pipeline maintenance.

[0020] As an optional technical solution of this utility model, the top surface of the support plate 4 is fixedly connected with two symmetrically arranged pins 13. The liquid storage cylinder 6 is engaged with the support plate 4 through the pins 13. The engagement of the pins 13 on the top surface of the support plate 4 with the liquid storage cylinder 6 can play an auxiliary positioning role for the liquid storage cylinder 6, preventing the liquid storage cylinder 6 from rotating or shifting during stirring or movement. Combined with the fixing of the locking ring 7 and the limiting ring 5, the stability of the liquid storage cylinder 6 installation is further improved.

[0021] As an optional technical solution of this utility model, two symmetrically arranged baffle plates 14 are fixedly connected to the inner wall of the frame 1. A guide rod 15 is fixedly connected between the baffle plate 14 and the frame 1. The bearing plate 4 is slidably connected to the guide rod 15. The baffle plate 14 and the guide rod 15 on the inner wall of the frame 1 cooperate to provide precise guidance for the lifting and lowering of the bearing plate 4, avoid the bearing plate 4 from tilting or shaking during the movement, ensure that the liquid storage cylinder 6 can be lifted and lowered smoothly, and ensure the precise docking of the spline shaft 10 and the spline sleeve 9, and the connecting pipe 12 and the liquid storage cylinder 6.

[0022] As an optional technical solution of this utility model, a locking bolt 16 is rotatably connected to one side of the baffle plate 14. The screw part of the locking bolt 16 is threadedly connected to the bearing plate 4. The locking bolt 16 on one side of the baffle plate 14 is threadedly connected to the bearing plate 4, which can lock the bearing plate 4 after it is raised or lowered to the designated position, preventing the bearing plate 4 from being displaced due to accidental force, ensuring the stable connection between the stirring component 8 and the liquid storage tank 6, and between the connecting pipe 12 and the liquid storage tank 6, and ensuring the safe operation of the device.

[0023] As an optional technical solution of this utility model, an electrical control box 17 is fixedly connected to one side of the frame 1. The motor 20 and the water pump 11 are both electrically connected to the electrical control box 17. The electrical control box 17 on one side of the frame 1 centrally controls the motor 20 and the water pump 11, which makes it convenient for operators to uniformly regulate the stirring and liquid addition process, reduce the tediousness of individual operation, and at the same time realize the coordinated work of the motor and the water pump, improving the automation level and operation convenience of the copper liquid addition device.

[0024] As an optional technical solution of this utility model, the top surface of the base plate 2 is fixedly connected to two symmetrically arranged top plates 18 by a vertically arranged support rod. Two clearance grooves 19 adapted to the top plates 18 are opened through one side of the limiting ring 5. The two clearance grooves 19 correspond to the two top plates 18 respectively. The top plates 18 on the top surface of the base plate 2 are adapted to the clearance grooves 19 of the limiting ring 5. When the bearing plate 4 is lowered, the top plates 18 can pass through the clearance grooves 19 to support the bottom of the liquid storage cylinder 6, share the pressure of the liquid storage cylinder 6 on the bearing plate 4, avoid the bearing plate 4 from being deformed by long-term stress, and extend the service life of the device.

[0025] A copper melting solution adding device, the working principle of which is as follows: 1): When the liquid storage tank 6 needs to be replaced, first remove the flange bolts between the connecting pipe 12 and the liquid storage tank 6 to separate the pipeline.

[0026] 2): Loosen the bolts connecting the locking ring 7 and the limit ring 5, then start the hydraulic cylinder 3 to drive the bearing plate 4 to move downward along the guide rod 15 until the spline shaft 10 disengages from the spline sleeve 9.

[0027] 3): Continue to control the hydraulic cylinder 3 to descend, so that the bearing plate 4 drives the liquid storage cylinder 6 to move down, so that the top plate 18 on the bottom plate 2 passes through the relief groove 19 of the limit ring 5, and gradually pushes the liquid storage cylinder 6 out of the limit ring 5. At the same time, the liquid storage cylinder 6 disengages from the pin 13, and finally completes the disassembly of the liquid storage cylinder 6.

[0028] In summary, when the copper molten metal filling device needs to be replaced, the flange bolts between the connecting pipe 12 and the storage tank 6 are first removed to separate the pipeline; the bolts connecting the locking ring 7 and the limiting ring 5 are loosened, and then the hydraulic cylinder 3 is started to drive the bearing plate 4 to move downward along the guide rod 15 until the spline shaft 10 disengages from the spline sleeve 9; the hydraulic cylinder 3 is continued to descend, allowing the bearing plate 4 to move the storage tank 6 downward, so that the top plate 18 on the bottom plate 2 passes through the clearance groove 19 of the limiting ring 5, gradually pushing the storage tank 6 out of the limiting ring 5, while the storage tank 6 disengages from the pin 13, thus completing the disassembly of the storage tank 6; when installing a new storage tank 6, the operation is reversed so that the top plate 18 assists in lifting the storage tank 6 into the limiting ring 5, and after being positioned by the pin 13, the bolts of the locking ring 7 are tightened, and then the hydraulic cylinder 3 is raised to connect the spline shaft 10 with the spline sleeve 9, and finally the flange is connected to complete the pipeline installation. Through the cooperation of the top plate 18 and the clearance groove 19, the hydraulic cylinder 3 is used to lift and install the liquid storage cylinder 6 automatically, replacing the laborious operation of manual lifting. The detachable design of the flange connection and bolt fixation makes the separation of the pipeline and the liquid storage cylinder easier and avoids the cumbersome disassembly of traditional complex connection structures. The snap-fit ​​of the pin shaft 13 and the sliding fit of the spline bushing ensure accurate positioning when replacing the liquid storage cylinder, greatly simplifying the maintenance process and reducing the difficulty of operation. When the device is running, the motor 20 drives the agitator 8 to rotate through the spline shaft 10 and the spline bushing 9 to agitate the copper-plated liquid in the liquid storage cylinder 6. When the hydraulic cylinder 3 drives the bearing plate 4 to rise and fall, the guide rod 15 ensures its smooth movement and prevents the liquid storage cylinder 6 from shaking. When the liquid storage cylinder 6 reaches the top plate 18, the guide rod 15 ensures its smooth movement and prevents the liquid storage cylinder 6 from shaking. After positioning, tighten the locking bolt 16 on the baffle plate 14 to fix it in place with the threaded connection of the support plate 4; the electrical control box 17 synchronously regulates the operation of the motor 20 and the water pump 11 to ensure that stirring and liquid addition are carried out in tandem; the sliding connection between the spline shaft 10 and the spline sleeve 9 ensures power transmission without affecting the lifting and lowering of the liquid storage tank 6; the continuous stirring of the stirring component 8 can prevent the copper liquid from settling; the cooperation between the guide rod 15 and the locking bolt 16 prevents the support plate 4 from moving accidentally and ensures the stable connection between the liquid storage tank 6 and each component; the centralized control of the electrical control box 17 improves the ease of operation; the top plate 18 provides support when the liquid storage tank descends, shares the pressure of the support plate 4, extends the service life of the device, and enhances the overall operational stability and safety.
