[0003] In the current existing technology, the existing tin solution is mixed with a chemical agent, and then through the sedimentation method, the tin solution is gradually solidified. However, the solid tin will be in a granular state after solidification. When the granular solid tin is extracted and recovered, the chemical agent will be absorbed out together. This chemical agent has certain corrosiveness. Therefore, when the solid tin is extracted, employees need to use clean water to wash the solid tin, and the washing water will be discharged together with the chemical agent, thus causing pollution to the surrounding environment. Moreover, when employees take the solid tin, they will also be corroded due to contact with the chemical agent.

Detailed implementation

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0026] The following gives specific embodiments.

[0027] Please refer to Figure 1 - Figure 6 , the present invention provides a waste tin liquid recovery device for the production of an integrated circuit packaging line, including an anti-slosh pad 11 and a stirring sedimentation tank 12 movably sleeved on the outer surface of the top of the anti-slosh pad 11, a docking sleeve 13 detachably installed at the outer bottom edge position of the stirring sedimentation tank 12, a motor 3 14 detachably installed on the inner wall surface of the stirring sedimentation tank 12, a tin discharge pipe 127 fixedly connected to the outer surface of the stirring sedimentation tank 12 and located at the bottom edge position and movably sleeved on the inner wall surface of the docking sleeve 13, a separation tank 132 detachably installed on the outer surface of one end of the docking sleeve 13, a liquid collection bladder 135 provided on the outer surface of the separation tank 132, partition strips 133 evenly distributed and fixedly connected to the inner wall surface of the separation tank 132, a closing plate 134 on the inner wall surface of the separation tank 132 and located on the outer surface of one end of the partition strip 133, a drive track 136 movably sleeved on the outer surface of the docking sleeve 13, and a motor 2 131 provided on the outer surface of one end of the drive track 136;

[0028] During operation, it cooperates with the tin discharge pipe 127 to extract the solid tin inside the anti-vibration cushion table 11 and divert the solid tin into the inside of the separation tank 132. At the same time, it cooperates with the second motor 131 to push the transmission track 136, so that the second motor 131 on the outer surface of the tin discharge pipe 127 rotates rapidly under the push of the transmission track 136. Under the action of centrifugal force, the solid tin will gradually adhere to the inner wall surface of the separation tank 132. Under the action of centrifugation, the chemical agent inside the solid tin will pass through the separation tank 132 and enter the inside of the liquid collection bladder 135, achieving the effect of separating the solid tin and the chemical agent by centrifugation. When the chemical agent on the surface of the solid tin is cleaned, stop rotating the separation tank 132, peel the separation tank 132 from the surface of the tin discharge pipe 127, open the drain valve on the surface of the separation tank 132 to discharge the chemical agent inside the separation tank 132 into the chemical agent collection pool, and peel the closing plate 134 from the inside of the separation tank 132, and wash the solid tin with water. With a little chemical agent remaining diluted by the water, it will not harm the environment and employees.

[0029] Further, as Figures 1 to 6 shown, a liner sleeve 121 is fixedly connected to the inner bottom wall surface of the stirring and sedimentation tank 12. An infiltration trough 122 is provided at the inner bottom edge position of the liner sleeve 121. A filter layer 125 that is movably sleeved on the outer surface of the liner sleeve 121 is provided on the inner middle wall surface of the stirring and sedimentation tank 12. The outer surface of the third motor 14 is detachably installed on the outer surface of the filter layer 125. A first motor 123 is fixedly installed on the inner top wall surface of the liner sleeve 121. Two liquid inlet pipes 124 are provided on the outer surface of the liner sleeve 121 and at the top edge position of the stirring and sedimentation tank 12. A liquid discharge pipe 126 is fixedly installed on the top surface of the stirring and sedimentation tank 12, and one end of the liquid discharge pipe 126 extends to the top edge position of the filter layer 125. A connecting rod a1 is fixedly connected to the outer surface of the output end of the first motor 123. A scraping and stirring plate a2 that is movably sleeved on the inner wall surface of the infiltration trough 122 is fixedly connected to the outer surface of the connecting rod a1. A limiting rod 141 is fixedly connected to the outer surface of the output end of the third motor 14. An arc plate 142 is fixedly connected to one end of the limiting rod 141. An outer differentiation strip 143 is fixedly connected to the outer surface of the arc plate 142. An inner differentiation strip 144 is fixedly connected to the inner wall surface of the arc plate 142.

[0030] During operation, two groups of liquid inlet pipes 124 are used to sequentially pour waste tin liquid and chemical agents into the inner liner sleeve 121. At the same time, the first motor 123 is used to rotate the scraping and stirring plate a2 on the outer surface of the connecting rod a1, so that the falling chemical agent and waste tin liquid are stirred and mixed, enabling the chemical agent to fully react with the waste tin liquid. The initially mixed waste liquid will enter the inside of the stirring and sedimentation tank 12 through the permeation trap 122. At this time, the third motor 14 on the outer surface of the filter layer 125 is used to perform secondary stirring and mixing treatment on the waste liquid inside the stirring and sedimentation tank 12, achieving the effect of fully mixing and chemically reacting the waste tin liquid and the chemical agent through multiple repeated stirrings. After full mixing, the stirring is stopped to allow the waste tin liquid to undergo natural sedimentation and solidification treatment. After the waste tin liquid has settled and separated, clean water is poured into the inner liner sleeve 121 to dilute the corrosiveness of the chemical agent. At the same time, the increase in clean water is used to raise the height of the internal liquid. The excess water that spreads over the filter layer 125 after the solidified tin is filtered by the filter layer 125 is absorbed and discharged through the drain pipe 126. After dilution, through natural sedimentation, the solidified tin settles at the bottom of the stirring and sedimentation tank 12. At this time, the tin discharge pipe 127 is used to absorb the water inside the stirring and sedimentation tank 12, and the fluidity of the water will carry the solidified tin into the inside of the separation tank 132 together. After the inside of the separation tank 132 is filled with solid tin, the separation tank 132 is used to perform solid-liquid separation treatment on the solid tin. After collecting the solid tin, the solid tin inside the stirring and sedimentation tank 12 is processed again.

[0031] Working principle: Two groups of liquid inlet pipes 124 are used to sequentially pour waste tin liquid and chemical agents into the inner liner sleeve 121. At the same time, the first motor 123 is used to rotate the scraping and stirring plate a2 on the outer surface of the connecting rod a1, so as to stir and mix the falling chemical agents and waste tin liquid, enabling the chemical agents to fully react with the waste tin liquid. The initially mixed waste liquid will enter the inside of the stirring and settling tank 12 through the permeation trap 122. At this time, the third motor 14 on the outer surface of the filter layer 125 is used to perform secondary stirring and mixing treatment on the waste liquid inside the stirring and settling tank 12, achieving the effect of fully mixing and chemically reacting the waste tin liquid and chemical agents through repeated stirring. After full mixing, the stirring is stopped to allow the waste tin liquid to naturally settle and solidify. After the waste tin liquid settles and separates, clean water is poured into the inside of the inner liner sleeve 121 to dilute the corrosiveness of the chemical agent, and at the same time, the height of the internal liquid is increased by the addition of clean water. The solidified tin is filtered by the filter layer 125, and the excess water source will spread over the filter layer 125 and is absorbed and discharged through the drain pipe 126. After dilution, through natural settlement, the solidified tin settles at the bottom layer of the stirring and settling tank 12. At this time, the tin discharge pipe 127 is used to absorb the water source inside the stirring and settling tank 12, and the fluidity of the water source will carry the solidified tin into the inside of the separation tank 132 together. When the inside of the separation tank 132 is filled with solid tin, the separation tank 132 is used to perform solid-liquid separation treatment on the solid tin. After collecting the solid tin, the solid tin inside the stirring and settling tank 12 is processed for the second time;

[0032] The tin discharge pipe 127 is used to extract the solid tin inside the anti-slosh pad platform 11 and guide the solid tin into the inside of the separation tank 132. At the same time, the second motor 131 is used to push the transmission track 136, so that the second motor 131 on the outer surface of the tin discharge pipe 127 rotates rapidly under the push of the transmission track 136. Under the action of centrifugal force, the solid tin will gradually adhere to the inner wall surface of the separation tank 132. Under the action of centrifugation, the chemical agent inside the solid tin will pass through the separation tank 132 and enter the inside of the liquid collection bladder 135, achieving the effect of separating the solid tin and the chemical agent by centrifugation. When the chemical agent on the surface of the solid tin is cleaned, the rotation of the separation tank 132 is stopped, the separation tank 132 is peeled off from the surface of the tin discharge pipe 127, the drain valve on the surface of the separation tank 132 is opened to discharge the chemical agent inside the separation tank 132 into the chemical agent collection pool, and the closing plate 134 is peeled off from the inside of the separation tank 132, and the solid tin is washed with water. The remaining little chemical agent will not harm the environment and employees under the dilution of water.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
