Description

Technical Field

[0001] This utility model relates to the field of composite partition processing technology, specifically to an acid leaching device for composite partitions. Background Technology

[0002] In the field of composite partition processing, acid leaching is a key process to improve the performance of the partition. Its core requirements are to ensure the uniformity of acid leaching, control the cost of acid solution, and avoid interference from impurities.

[0003] Existing acid immersion devices for composite partitions mostly use a single acid inlet or static immersion method, which can easily lead to gradient differences in acid concentration within the acid immersion tank; Furthermore, the composite partition and the supporting structure are mostly in surface contact, and some areas of the partition are blocked, which prevents the acid from fully penetrating. This results in inconsistent acid immersion levels in different parts of the partition, affecting the stability of product performance.

[0004] In addition, most existing acid leaching devices for composite partitions discharge the acid directly after a single use, which not only consumes a large amount of high-concentration acid and increases production costs, but also generates a large amount of acidic waste liquid, increasing the burden of environmental treatment. In addition, existing acid leaching equipment for composite partitions mostly relies on manual handling of acid leaching frames for loading and unloading, which is not only labor-intensive and inefficient, but also poses a safety hazard of operators coming into contact with acidic substances; moreover, the manual positioning of the acid leaching frames is not accurate enough, which can easily lead to partition displacement, further affecting the acid leaching quality. Utility Model Content

[0005] The purpose of this invention is to provide an acid leaching device for composite partitions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an acid leaching device for composite partitions, comprising an acid leaching tank, an acid leaching frame disposed inside the acid leaching tank, a bottom support column disposed at the bottom of the acid leaching frame, a side support column disposed on the side of the acid leaching frame, side guide rails disposed on both sides of the acid leaching frame, a support beam movably mounted between the two sets of side guide rails, the support beam being located above the acid leaching frame, an electric push rod disposed on the support beam, a suspension beam disposed at the bottom of the electric push rod, two sets of suspension hooks symmetrically disposed at the bottom of the suspension beam, a suspension rod disposed at the top of the acid leaching frame in conjunction with the suspension hooks, a plurality of spray pipes uniformly disposed inside the acid leaching tank, a plurality of spray heads uniformly disposed on the spray pipes, and a liquid inlet pipe disposed at the input end of the spray pipes.

[0007] The present invention is further configured such that two sets of liquid outlet pipes are symmetrically arranged at the lower end of the side wall of the acid leaching tank, and multiple suction nozzles are evenly arranged on the liquid outlet pipes. A drain pipe is connected to the output end of the liquid outlet pipes, and an acid circulation structure is provided at the tail end of the drain pipes. A pump body can be installed at the drain pipes to drive the flow of acid. The liquid is drawn out through the suction nozzles to the liquid outlet pipes, and then flows through the liquid outlet pipes to the drain pipes, and is discharged from the acid leaching tank through the drain pipes.

[0008] The present invention is further configured such that the acid circulation structure includes a static mixer, the input end of which is connected to the drain pipe, and a circulation supply pipe is provided between the output end and the inlet pipe. An acid replenishment pipe is connected to the input end of the static mixer, and a high-concentration acid source is connected to the acid replenishment pipe. The acid discharged through the drain pipe will be mixed with the newly replenished acid in the acid replenishment pipe in the static mixer to form a new acid solution of the correct concentration, which is then transported back to the inlet pipe through the circulation supply pipe. This improves the utilization rate of the acid solution.

[0009] The present invention is further configured such that a first acid concentration detector is installed on the drain pipe and a second acid concentration detector is installed on the circulating supply pipe. The first acid concentration detector can detect the concentration of the discharged acid and control the acid supply volume of the acid replenishment pipe according to this concentration value, so that the newly added replenishment liquid and the discharged liquid can be fully mixed in the static mixer and then transported to the inlet pipe through the circulating supply pipe to realize the supply of liquid to the spray pipe. The second acid concentration detector can be used to detect whether the concentration of the mixed acid meets the standard, further improving the accuracy of acid concentration adjustment and improving the acid leaching effect of the composite partition.

[0010] The present invention is further configured such that a protective cover is provided on the outer side of the outlet pipe, and the edge of the protective cover is sealed and installed on the side wall of the acid leaching tank. A backflush pipe is provided inside the protective cover, and multiple high-pressure nozzles are evenly arranged on the backflush pipe facing the protective cover. A backflush supply pipe is provided between the input end of the backflush pipe and the inlet pipe, and a pressure pump is provided on the backflush supply pipe. The protective cover can prevent impurities in the acid leaching solution from entering the outlet pipe through the suction nozzle, thus isolating the impurities. The backflush pipe can realize automatic cleaning of the protective cover. When the protective cover needs to be automatically cleaned, the pressure pump can be started, so that the liquid in the inlet pipe can be transported to the backflush pipe through the backflush supply pipe and sprayed outward toward the protective cover through the high-pressure nozzles. In this way, automatic cleaning of the protective cover can be achieved. Here, a program can be set to clean at regular intervals through a PLC control system, or a differential pressure gauge can be installed inside and outside the protective cover to realize quantitative cleaning by detecting the pressure difference. The above methods can all be achieved by existing technology, and the present invention will not elaborate on them.

[0011] The present invention is further configured such that a sedimentation hopper is provided at the bottom of the acid leaching tank, a slag discharge pipe is provided at the bottom of the sedimentation hopper, and a valve is provided on the slag discharge pipe. The sedimentation hopper allows impurities generated during the acid leaching process to precipitate in the sedimentation hopper at the bottom of the acid leaching tank, thereby allowing the impurities to separate from the acid leaching liquid, preventing the impurities from affecting the composite partition during the acid leaching process. At the same time, it facilitates the discharge of the precipitated impurities. When discharging, the valve is opened and the slag discharge pipe is opened to discharge the precipitated impurities.

[0012] The present invention is further configured such that a limiting edge is provided inside the acid leaching tank, and a locking edge is provided on the outer side wall of the acid leaching frame. The locking edge is attached to the limiting edge. The cooperation between the limiting edge and the locking edge can prevent the acid leaching frame from settling to the bottom and contacting the impurities at the bottom after entering the acid leaching tank, thereby improving the acid leaching effect of the composite partition.

[0013] The present invention is further configured such that a mounting frame is provided on the supporting crossbeam, and a movable trolley is provided at both ends of the mounting frame. The movable trolley is correspondingly mounted on the side guide rail, and the movement of the supporting crossbeam on the acid leaching tank is realized by the movement of the movable trolley on the side guide rail.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. It significantly improves the uniformity of acid leaching and ensures stable product quality. This invention solves the problem of uneven acid leaching in traditional methods through a dual-structure design: Firstly, the bottom and side support columns within the acid leaching frame change the "surface contact" support of the composite partition to "point contact," reducing the area obstructed by the partition and allowing the acid to fully contact all surfaces of the partition. Secondly, multiple sets of spray pipes and spray heads are evenly distributed within the acid leaching tank, ensuring uniform spraying of the acid onto the partition and avoiding concentration differences caused by a single acid inlet. This design ensures consistent acid leaching across all areas of the partition, effectively improving product quality stability.

[0015] 2. Enables acid recycling, reducing costs and promoting energy conservation and environmental protection. This invention establishes a complete acid circulation system. Used acid is transported to a static mixer via an outlet pipe and a drain pipe. Simultaneously, a first acid concentration detector monitors the concentration of the discharged acid in real time, controlling the replenishment pipe to supply high-concentration acid. After thorough mixing in the static mixer, the acid is returned to the inlet pipe via a circulation supply pipe for spraying. A second acid concentration detector verifies whether the mixed acid concentration meets the standards. This circulation mode significantly improves acid utilization and reduces acid discharge, thereby lowering production costs and alleviating environmental protection pressure.

[0016] 3. Effectively controls impurities and interference, reduces equipment maintenance, and improves acid leaching effect. This invention controls impurities from two aspects: impurity collection and pipeline protection. The sedimentation hopper at the bottom of the leaching tank collects impurities generated during leaching and discharges them periodically through the slag discharge pipe, preventing impurities from adhering to the baffles and affecting the leaching effect. The protective cover on the outside of the outlet pipe prevents impurities from entering the pipeline, and the backflushing pipe inside the cover, in conjunction with the high-pressure nozzle and pressurizing pump, can automatically clean the cover periodically or as needed, preventing impurities from clogging the suction nozzle. This design reduces the interference of impurities on the leaching process, lowers equipment maintenance frequency, and further ensures the leaching effect and stable operation of the equipment.

[0017] 4. Automated loading and unloading design significantly improves work efficiency. This invention utilizes a supporting beam, a mobile trolley, and an electric push rod to construct an automated loading and unloading system, replacing traditional manual handling. During automatic loading, after the acid-soaking partition is placed into the acid-soaking frame, the suspension hook and suspension rod work together to connect the frame to the suspension beam. The mobile trolley then precisely delivers the frame above the acid-soaking tank along the side guide rail, eliminating the need for manual positioning and reducing preparation time. After acid soaking, the electric push rod moves the suspension beam and suspension hook, engaging with the suspension rod to lift and smoothly retrieve the acid-soaking frame, preventing acid splashing and partition misalignment. The mobile trolley then transports the frame to the designated area. The entire process requires no manual contact with the acid or equipment, ensuring safety and minimizing operational errors. This design eliminates cumbersome manual steps, enables continuous operation, shortens loading and unloading time per cycle, and reduces labor costs and error rates. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution: Please refer to Figures 1-7 A composite partition acid immersion device includes an acid immersion tank 1, wherein multiple acid immersion tanks 1 can be arranged in a row. An acid immersion frame 2 is provided inside the acid immersion tank 1. The acid immersion frame 2 is a wire mesh frame. A bottom support column 3 is provided at the bottom of the inside of the acid immersion frame 2, and side support columns 4 are provided on the inside sides of the acid immersion frame 2. Side guide rails 5 are provided on both sides of the acid immersion frame 2. A support beam 6 is movably installed between the two sets of side guide rails 5. The support beam 6 can be fixed to the upper sides of the acid immersion tank 1 using an existing bracket structure. The crossbeam 6 is located above the pickling frame 2. An electric push rod 7 is installed on the crossbeam 6. A suspension beam 8 is installed at the bottom of the electric push rod 7. Two sets of suspension hooks 9 are symmetrically installed at the bottom of the suspension beam 8. A suspension rod 10 is installed at the top of the pickling frame 2 in conjunction with the suspension hooks 9. The suspension hooks 9 and the suspension rods 10 can be hooked together. Multiple spray pipes 11 are evenly arranged inside the pickling tank 1. Multiple spray heads 12 are evenly arranged on the spray pipes 11. A liquid inlet pipe 13 is installed at the input end of the spray pipes 11.

[0022] Please see Figures 1-7As one embodiment of the acid leaching tank 1: two sets of outlet pipes 14 are symmetrically arranged at the lower end of the side wall of the acid leaching tank 1. Multiple suction nozzles 15 are evenly arranged on the outlet pipes 14. The output end of the outlet pipes 14 is connected to a drain pipe 16. An acid circulation structure is provided at the tail end of the drain pipe 16. A pump body can be installed at the drain pipe 16 to drive the flow of acid. The liquid is drawn out through the suction nozzles 15 to the outlet pipes 14, and then flows through the outlet pipes 14 to the drain pipe 16, and is discharged from the acid leaching tank 1 through the drain pipe 16.

[0023] Please see Figures 1-7 As one implementation of the acid circulation structure: the acid circulation structure includes a static mixer 17. The input end of the static mixer 17 is connected to the drain pipe 16, and a circulation supply pipe 18 is provided between the output end and the inlet pipe 13. The input end of the static mixer 17 is connected to an acid replenishment pipe 19. The acid replenishment pipe 19 is connected to a high-concentration acid source. The acid discharged through the drain pipe 16 will be mixed with the newly replenished acid in the acid replenishment pipe 19 in the static mixer 17 to form a new acid solution with the correct concentration. This solution is then transported back to the inlet pipe 13 through the circulation supply pipe 18. In this way, the utilization rate of the acid solution can be improved.

[0024] Please see Figures 1-7 As one implementation of the drain pipe 16: a first acid concentration detector 20 is installed on the drain pipe 16, and a second acid concentration detector 21 is installed on the circulating supply pipe 18. The first acid concentration detector 20 can detect the concentration of the discharged acid and control the acid supply amount of the acid replenishment pipe 19 according to this concentration value, so that the newly added replenishment liquid and the discharged liquid can be fully mixed in the static mixer 17 and then transported to the inlet pipe 13 through the circulating supply pipe 18 to realize the supply of liquid to the spray pipe 11. The second acid concentration detector 21 can be used to detect whether the concentration of the mixed acid liquid meets the standard, further improving the accuracy of acid concentration adjustment and improving the acid leaching effect of the composite partition.

[0025] Please see Figures 1-7As one embodiment of the outlet pipe 14: a protective cover 22 is provided on the outer side of the outlet pipe 14. The edge of the protective cover 22 is sealed and installed on the side wall of the acid leaching tank 1. A backflush pipe 23 is provided inside the protective cover 22. Multiple high-pressure nozzles 24 are evenly arranged on the backflush pipe 23 facing the protective cover 22. A backflush supply pipe 25 is provided between the input end of the backflush pipe 23 and the inlet pipe 13. A pressure pump 26 is provided on the backflush supply pipe 25. The protective cover 22 can prevent impurities in the acid leaching solution from entering the outlet pipe 14 through the suction nozzle, thus achieving impurity isolation and backflush. The installation of pipe 23 enables automatic cleaning of the protective cover 22. When the protective cover 22 needs automatic cleaning, the pressurization pump 26 can be started, so that the liquid in the inlet pipe 13 can be transported to the backflushing pipe 23 through the backflushing supply pipe 25, and sprayed outward toward the protective cover 22 through the high-pressure nozzle 24. In this way, the protective cover 22 can be automatically cleaned. Here, the program can be set to clean at regular intervals through the PLC control system, or a differential pressure gauge can be installed inside and outside the protective cover 22 to achieve quantitative cleaning by detecting the pressure difference. The above methods can all be achieved by existing technology, and this utility model will not elaborate further.

[0026] Please see Figures 1-7 As one embodiment of the pickling tank 1: a sedimentation hopper 27 is provided at the bottom of the pickling tank 1, and a slag discharge pipe 28 is provided at the bottom of the sedimentation hopper 27. A valve 29 is provided on the slag discharge pipe 28. The sedimentation hopper 27 allows impurities generated during the pickling process to precipitate in the sedimentation hopper 27 at the bottom of the pickling tank 1, thereby allowing the impurities to separate from the pickling liquid and avoiding the impurities from affecting the composite partition during the pickling process. At the same time, it facilitates the discharge of the precipitated impurities. When discharging, the valve 29 is opened and the slag discharge pipe 28 is opened to discharge the precipitated impurities.

[0027] Please see Figures 1-7 As one embodiment of the pickling tank 1: the pickling tank 1 is provided with a limiting edge 30 inside, and the outer wall of the pickling frame 2 is provided with a locking edge 31. The locking edge 31 is attached to the limiting edge 30. The cooperation between the limiting edge 30 and the locking edge 31 can prevent the pickling frame 2 from settling to the bottom and coming into contact with the impurities at the bottom after entering the pickling tank 1, thereby improving the pickling effect of the composite partition.

[0028] Please see Figures 1-7 As one implementation of the support beam 6: a mounting frame 32 is provided on the support beam 6, and a movable trolley 33 is provided at both ends of the mounting frame 32. The movable trolley 33 is installed on the side guide rail 5. The movement of the support beam 6 on the acid immersion tank 1 is achieved by the movement of the movable trolley 33 on the side guide rail 5.

[0029] In summary, the working principle and specific workflow of this utility model are as follows: This invention provides a bottom support column 3 and a side support column 4 inside the pickling frame 2. When the composite partition to be pickled is placed inside the pickling frame 2, the composite partition is supported by the side support column 4 and the bottom support column 3. This changes the traditional contact between the composite partition and the pickling frame 2 from surface contact to point contact, reduces the obstruction area of ​​the composite partition during pickling, improves the sufficiency of the composite partition during pickling, and enhances the pickling effect of the composite partition. In use, this utility model allows for quick and convenient installation of the acid immersion frame 2 at the bottom of the supporting beam 6 by hooking the suspension rod 10 with the suspension hook 9. The moving trolleys 33 on both sides are controlled to move synchronously, thereby controlling the movement of the supporting beam 6. When the pickling frame 2 and the internal composite partition are moved above the corresponding pickling tank 1, the horizontal movement of the supporting beam 6 is stopped. Then, the electric push rod 7 is activated, and the suspension beam 8 is controlled by the electric push rod 7 to drive the suspension hook 9 to descend, so that the acid immersion frame 2 gradually descends into the acid solution in the acid immersion box 1, so that the locking edge 31 is placed on the limiting edge 30, and the acid immersion frame 2 is stably placed in the acid immersion box 1. In this utility model, limiting telescopic rods can be set on both sides of the electric push rod 7. The limiting telescopic rods can extend and retract synchronously with the electric push rod 7 to limit the lateral displacement of the suspension beam 8, avoid the electric push rod 7 being subjected to force on one side, and help improve the lifting stability of the suspension beam 8. During the acid leaching process, acid solution of the appropriate concentration can be transported to the spray pipe 11 through the inlet pipe 13 and sprayed out evenly through the spray head 12. This utility model, by setting up multiple spray pipes 11 and spray heads 12 in combination, can avoid the situation of inconsistent acid concentration in the acid leaching tank 1 caused by the traditional single acid inlet, and improve the uniformity of the composite partition in the acid leaching process. At the same time, the liquid is drawn out through the suction nozzle 15 to the outlet pipe 14, and then flows through the outlet pipe 14 to the drain pipe 16, and is discharged from the acid leaching tank 1 through the drain pipe 16; The acid discharged through the drain pipe 16 will be mixed with the acid newly supplied through the acid replenishment pipe 19 in the static mixer 17 to form a new acid solution with the correct concentration. This solution will then be transported back to the inlet pipe 13 through the circulation supply pipe 18, thereby improving the utilization rate of the acid solution. During the above process, the first acid concentration detector 20 detects the concentration of the acid discharged in the drain pipe 16 in real time. The controller automatically adjusts the acid supply in the acid replenishment pipe 19 according to the concentration value, so that the newly added replenishment liquid and the discharged liquid can be fully mixed in the static mixer 17 and then transported back to the inlet pipe 13 through the circulating supply pipe 18 to realize the supply of liquid to the spray pipe 11. The second acid concentration detector 21 can be used to detect whether the concentration of the mixed acid solution meets the standard, thereby improving the accuracy of acid concentration preparation and enhancing the acid immersion effect of the composite partition. The present invention provides a protective cover 22 on the outside of the liquid outlet pipe 14. The protective cover 22 can prevent impurities in the acid leaching solution from entering the liquid outlet pipe 14 through the suction nozzle 15, thereby achieving the isolation of impurities. The backflush pipe 23 can enable the automatic cleaning of the protective cover 22. When the protective cover 22 needs to be cleaned automatically, the pressurizing pump 26 can be started so that the liquid in the inlet pipe 13 can be transported to the backflush pipe 23 through the backflush supply pipe 25 and sprayed outward toward the protective cover 22 through the high-pressure nozzle 24. In this way, the automatic cleaning of the protective cover 22 can be achieved. In this invention, the opening and closing of all fluids in the pipeline and the flow rate are controlled by corresponding valves; valves are common components of pipeline systems, and their specific models and installation methods are not described in detail in this invention. In this utility model, the synchronous control of the moving trolleys on both sides of the supporting crossbeam 6 can be achieved through the following existing technology: 1. Centralized control: (Unified scheduling by a "central brain") This is the most common solution in existing technology, which directly manages the movement of two groups of cars through a central controller (such as a PLC, industrial computer, or embedded motherboard). The essence is "unified instructions, separate execution". The workflow is as follows: The central controller has preset synchronous motion logic (such as trajectory coordinates, velocity curves, and time nodes). The controller sends commands (such as "current speed 0.3m / s" and "target position (5,3)") to the two groups of cars in real time through communication modules (such as RS485, EtherCAT, WiFi, 4G). The car's local controller (such as MCU or motion control card) receives instructions, drives the motor to execute them, and provides real-time feedback on its own status (position, speed) through sensors such as encoders and GPS. The central controller compares the feedback data from the two groups of vehicles and dynamically adjusts the commands (e.g., if group A is too slow, increase its speed; if group B is too fast, decrease its speed) to achieve closed-loop correction.

[0030] Core components: Central controller: responsible for logic operations and instruction issuance (such as Siemens S7-1200 PLC, Raspberry Pi 4B); Communication module: Low latency and high reliability are required (EtherCAT is preferred for industrial scenarios, WiFi6 can be selected for civilian scenarios). Local sensors for the vehicle: used for status feedback (such as photoelectric encoders (accuracy in mm), lidar (positioning accuracy in cm), GPS (outdoor accuracy in meters).

[0031] 2. Distributed control (“autonomous negotiation” collaboration) The two groups of vehicles do not require a central controller. They achieve synchronization through mutual communication and local computing. Essentially, this is "information sharing and collaborative decision-making," making it suitable for scenarios without a fixed control center (such as outdoor inspections and multi-vehicle platooning).

[0032] Workflow: The two groups of vehicles are pre-set with a unified "synchronization rule" (such as "taking group A as the reference, group B follows the speed of group A" and "the two groups exchange position data every 100ms"). The car exchanges its status (location, speed, remaining battery power) in real time via wireless communication (such as Bluetooth 5.0, LoRa, 5G). Each group of cars' local controllers autonomously adjusts motion parameters based on the other group's data and synchronization rules (e.g., when group A accelerates, group B accelerates synchronously according to group A's acceleration). If a group of cars deviates from its position (e.g., group B lags behind group A by 5cm), the local controller will automatically correct it (e.g., group B temporarily increases its speed by 0.1m / s until it catches up).

[0033] In this utility model, the operation of relevant electrical components such as pumps and electric push rods can be controlled by a PLC control system according to a set program. The specific working process and working principle of this utility model have been described in detail. Based on the above working process and working principle, those skilled in the art should know the specific circuit connection relationship and implement it through existing technology. Furthermore, the circuit connection relationship between relevant electrical components and the specific driver program are not the subject of protection of this utility model, and this utility model will not elaborate on them.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
