Description
Technical Field
[0001] The utility model relates to the technical field of stripping tin solution recovery, in particular to a stripping tin solution recovery device. Background Technique
[0002] The stripping tin solution, also known as tin stripping water, tin stripping solution, tin stripping agent, tin removing water, and etching solution, is a professional tin stripping agent widely used in the chemical industry. It can be operated by soaking or mechanical spraying, without any damage to the copper substrate and nickel substrate, and can remove copper rust, making the copper substrate shiny as new.
[0003] In the existing stripping tin solution recovery device, such as the Chinese utility model patent named "A Stripping Tin Solution Recovery and Filtration Device" with the publication number CN212894986U, it includes a containing bucket, a cover, a steam pipe, a condensing pipe, and a recovery bucket. The containing bucket is used to hold the stripping tin solution. An accommodating cavity is opened inside the containing bucket. One end of the accommodating cavity is provided with an air inlet. The cover is connected to the containing bucket and seals the air inlet. An air inlet hole and an air outlet hole are provided on the cover. The air inlet hole and the air outlet hole are respectively communicated with the accommodating cavity. The steam pipe passes through the air inlet hole and is inserted into the inside of the containing bucket. The condensing pipe is inserted into the air outlet hole. The first end of the condensing pipe is communicated with the air outlet hole, and the second end of the condensing pipe is aligned with the bucket mouth of the recovery bucket. In the patent solution, the driving machine 700 is a motor. In the specification drawings, the driving machine 700 is suspended without any installation foundation, and it is not clear how it stably drives the connecting rod 600 to rotate. Moreover, in the above patent, it is described that "the driving machine 700 is in driving connection with the lead screw, and the rod body is connected to the steam plate 310. In this way, when the motor works, the lead screw rotates. Through the screw connection with the slider, the circular motion is converted into a linear motion, so that the driving machine 700 pulls the steam plate 310 to move linearly in the direction of approaching or departing from the bottom of the containing bucket 100". First, the position, connection situation, and size of the lead screw and the slider are not expressed in the specification drawings. This structure is a necessary structure for realizing the function, but it is not clearly shown in the patent solution. Second, it can be clearly seen from the specification drawings that the steam pipe 300 only passes through the hole opened at the top of the cover 200 without a limiting mechanism. When the driving machine 700 and the lead screw rotate, even if the lead screw is in screw connection with the slider, the steam pipe 300 and the steam plate 310 lack a limiting mechanism and may rotate synchronously with the lead screw and will not move linearly. Third, it can be seen from the specification drawings that the threaded structure at the top of the connecting rod 600 is short. Even if the steam pipe 300 and the steam plate 310 can move vertically and linearly, the moving distance is short, and the improvement effect on the contact between the steam and the stripping tin solution is limited. Finally, a large amount of steam is introduced into the stripping tin solution, and the steam will condense and mix with the stripping tin solution, making the stripping tin solution greatly diluted and the concentration cannot be determined, greatly increasing the difficulty of subsequent recovery and preparation of the concentration of the stripping tin solution, increasing the processes of measuring the concentration, removing water, or preparing raw materials, complicating the entire recovery process, and significantly increasing the cost. Therefore, it is necessary to design a stripping tin solution recovery device for the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a tin stripping solution recovery device, including an ionization tank 1, a top cover 2, a discharge pipe 3, an installation window 4, a cathode conductive plate 5, a sealing plate 6, a cathode wire 7, a cathode attachment plate 8, a positioning plate 9, a positioning groove 10, a positioning bolt 11, a positioning nut 12, an anode plate 13, an exhaust pipe 14, an adsorption cylinder 15, a top pipe 16, an igniter 17, a combustion-supporting gas nozzle 18, and an oxygen nozzle 19. The top cover 2 is installed on the top of the ionization tank 1. One bottom end of the ionization tank 1 is fixed with a discharge pipe 3. One end of the top of the top cover 2 is penetrated and provided with an installation window 4. The cathode conductive plate 5 is penetrated and installed in the installation window 4. The top end of the cathode conductive plate 5 is connected and fixed to the center of the bottom surface of the sealing plate 6. The sealing plate 6 is installed at one end of the top of the top cover 2. The center of the sealing plate 6 is penetrated and installed with a cathode wire 7. The cathode wire 7 is connected to the top of the cathode conductive plate 5. The bottom end of the cathode conductive plate 5 is connected to the cathode attachment plate 8. The other end of the top of the top cover 2 is penetrated and fixed with an anode plate 13. The center of the top cover 2 is penetrated and installed with an exhaust pipe 14. The top end of the exhaust pipe 14 is connected and fixed to the bottom end of the adsorption cylinder 15. The top end of the adsorption cylinder 15 is installed with a top pipe 16.
[0024] In this example, the sealing plate 6 is installed at one end of the top of the top cover 2 through bolts and nuts. The length and width of the sealing plate 6 are both greater than the length and width of the installation window 4. The above structural design enables the sealing plate 6 to stably block the installation window 4 and prevent the gas generated by electrolysis from leaking from the installation window 4.
[0025] A positioning plate 9 is fixedly installed on the top of the cathode attachment plate 8. A positioning groove 10 is opened on the top of the positioning plate 9. The inner wall of the positioning groove 10 fits with the positioning bolt 11. The positioning bolt 11 is fixedly installed on the top side of the cathode conductive plate 5. The end of the positioning bolt 11 is installed with a positioning nut 12. The positioning nut 12 fits with the outer side of the positioning plate 9. The above structural design enables the cathode attachment plate 8 and the cathode conductive plate 5 to be stably connected and fixed and quickly disassembled and decomposed.
[0026] The cathode attachment plate 8 and the cathode conductive plate 5 are in a snap-fit connection. The positioning plates 9 are symmetrically arranged on the top of the cathode attachment plate 8. The above structural design enables the cathode attachment plate 8 and the cathode conductive plate 5 to be quickly aligned and connected.
[0027] The side view shape of the positioning groove 10 is "U" shaped, and the positioning grooves 10 are equally spaced. The above structural design enables the positioning plate 9 to be quickly and closely connected or slid and separated from the positioning bolt 11 through the positioning groove 10.
[0028] The diameter of the top pipe 16 is smaller than the diameter of the exhaust pipe 14, and the centers of the top pipe 16 and the exhaust pipe 14 are on the same vertical line. The above structural design enables the gas to stay in the adsorption cylinder 15 for a long time.
[0029] A igniter 17 is fixedly installed on the front side of the top of the top pipe 16, a combustion-supporting gas nozzle 18 is fixed on one side of the top of the top pipe 16, and an oxygen nozzle 19 is fixed on the other side of the top of the top pipe 16. The above structural design can ignite and heat the gas discharged from the top pipe 16.
[0030] The combustion-supporting gas nozzle 18 and the oxygen nozzle 19 are symmetrically distributed about the center of the top pipe 16, and both the combustion-supporting gas nozzle 18 and the oxygen nozzle 19 are inclined towards the center of the top pipe 16. The above structure ensures that the gas discharged from the top pipe 16 can be fully ignited and heated, ensuring the treatment effect on different components in the gas.
[0031] Working principle: When using this device for stripping solution recovery, first add the stripping solution into the ionization tank 1 without the top cover 2 installed, and then fix the top cover 2 on the ionization tank 1. Power is supplied to the cathode wire 7 and the anode plate 13. The cathode attachment plate 8 and the anode plate 13 ionize the stripping solution in the ionization tank 1. The tin generated by ionization adheres to the surface of the cathode attachment plate 8, and gas is generated at the anode plate 13. The gas enters the adsorption cylinder 15 through the exhaust pipe 14. The filler in the adsorption cylinder 15 adsorbs the harmful components in the gas, and then the gas is discharged through the top pipe 16. Start the igniter 17 and spray the combustion-supporting gas through the combustion-supporting gas nozzle 18, and spray oxygen through the oxygen nozzle 19 to heat and burn the gas discharged from the top pipe 16 to decompose the harmful components;
[0032] After electrolysis for a period of time, power supply to the cathode wire 7 and the anode plate 13 is stopped. The nuts on the bolts connected to both sides of the sealing plate 6 are removed, and the sealing plate 6 is lifted upward, driving the cathode conductive plate 5 and the cathode attachment plate 8 to be vertically withdrawn from the installation window 4. The positioning nuts 12 on the symmetrically distributed positioning bolts 11 are rotated away from the surface of the positioning plate 9, and no longer squeeze the positioning plate 9 and the cathode conductive plate 5 to fit and fix. The cathode attachment plate 8 is moved to be separated from the cathode conductive plate 5. A new cathode attachment plate 8 is engaged with the cathode conductive plate 5. The positioning groove 10 on the new cathode attachment plate 8 is fitted with the positioning bolt 11. The positioning nut 12 is rotated to squeeze the positioning plate 9 on the new cathode attachment plate 8 and the cathode conductive plate 5 to fit and fix. The cathode conductive plate 5 and the cathode attachment plate 8 are inserted into the installation window 4 for reset. The nuts on the bolts connected to both sides of the sealing plate 6 are installed and reset. The whole device can carry out electrolysis again. The tin attached to the removed cathode attachment plate 8 is scraped off and collected. The ionized liquid is collected by opening the valve on the discharge pipe 3. This is the working principle of the tin stripping solution recovery device.
[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
