[0010] Preferably, a connecting rod is fixedly mounted on the lower end of the liquid storage tank, and a rotating rod is fixedly mounted on the lower end of the connecting rod.

[0011] Preferably, a driven gear is fixedly mounted on the circumferential end of the connecting rod, a second liquid outlet is penetrated through the lower end of the liquid storage tank, the second liquid outlet is matched in size with the first liquid outlet, and the toothed belt meshing sleeve is arranged on the circumferential end of the driving gear and the driven gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, a motor is provided to drive a transmission rod to rotate the rectangular vertical pipe, and stirring rods on both sides of the rectangular vertical pipe stir the electrolytic wastewater in the wastewater tank. At the same time, the liquid outlet groove at the side end of the rectangular vertical pipe cooperates with the liquid guide port of the movable pipe to realize the addition of alkaline solution from bottom to top, which can improve the mixing uniformity of the alkaline solution and the acidic electrolytic wastewater, make the neutralization reaction more sufficient and efficient, avoid the uneven local acid-base reaction caused by the top pouring type, and is conducive to the precise implementation of subsequent treatment links such as metal ion precipitation.

[0014] In the present invention, a bottom-up feeding function is realized by providing a movable tube and a rectangular vertical tube. Initially, the liquid guide port coincides with the bottommost liquid outlet groove. As the rectangular vertical tube rotates, the movable tube and its threaded tube rotate in the threaded groove and move upward.

The movable tube is located in the rectangular vertical tube and can play a certain protective role when discharging medicine. While the rectangular vertical tube drives the stirring rod to stir the electrolytic wastewater in the wastewater tank, the alkaline solution is discharged from the bottom to the top. Compared with the prior art, a medicine-discharging tube with adjustable height is directly inserted into the wastewater tank, which does not occupy additional space in the wastewater tank and avoids the phenomenon that the medicine-discharging tube may be corroded.

[0016] In the present invention, during the process of adding alkaline solution, since the movable tube rotates with the rectangular vertical tube, when the rectangular vertical tube drives the stirring rod to rotate and mix, the alkaline solution is thrown out from the liquid guide port and the liquid outlet trough due to inertia, and spreads farther in the lateral direction. Compared with the traditional static feeding method, the horizontal action range of the alkaline solution can be expanded, the mixing speed with the electrolytic wastewater is accelerated, the reaction time is shortened, and the wastewater treatment efficiency is improved.

[0017] In the present invention, by arranging a liquid storage tank and a tray to cooperate with each other, the alkaline solution enters the conduit connector and finally flows out only when the second liquid outlet of the liquid storage tank coincides with the first liquid outlet of the tray, thereby avoiding the problems of violent local reaction and large pH value fluctuation caused by a large amount of liquid addition at one time, so that the neutralization reaction proceeds smoothly, which is beneficial to ensuring the stability of water quality when treating wastewater.

That is, in the initial state, the alkaline solution will first be added to the bottom of the wastewater tank 1, and mixed with the electrolytic wastewater under the stirring of the stirring rod 25 on the rectangular standpipe 24;

[0030] When the rectangular stand 24 rotates, the movable tube 3 is driven to rotate, and the rotation of the movable tube 3 drives the threaded tube 32 to rotate in the thread groove 13. The threaded tube 32 rotates in the thread groove 13 and gradually moves upward. The upward movement of the threaded tube 32 gradually compresses the folded bellows 34 and the telescopic rod 35.

At 23, it will continue to move upward, and then gradually overlap with each liquid outlet trough 23 from bottom to top, and the alkaline solution in the liquid storage box 6 will also be discharged from the liquid outlet troughs 23 at different heights, so that in the process of treating electrolytic wastewater, the alkaline solution is added from bottom to top, so that the alkaline solution and the electrolytic wastewater are more evenly integrated, and when the alkaline solution is added, the movable tube 3 rotates with the rectangular standpipe 24, and the alkaline solution is thrown out from the liquid guide port 31 and the liquid outlet trough 23 by inertia, so that the alkaline solution spreads farther in the lateral direction;

[0031] A circular groove 51 is penetrated through the lower end of the tray 5, and a first liquid outlet 52 is also penetrated through the lower end of the tray 5. The end of the catheter connector 36 is rotatably installed on the inner side wall of the first liquid outlet 52.

[0032] Working principle:

[0033] The first step is that during the electrolysis of aluminum plates, sulfuric acid is a common electrolyte component. When the aluminum plate is used as an anode, aluminum atoms lose electrons and become aluminum ions that enter the solution. Acidic electrolytes are usually used to promote the electrolysis reaction. Therefore, the wastewater from the electrolysis of aluminum plates is mostly acidic wastewater. When it is treated, alkaline substances are added to neutralize the acidic components in the wastewater. Commonly used alkaline substances include sodium hydroxide, calcium hydroxide, etc.

[0034] In the second step, when the electrolytic wastewater is treated, the wastewater can be introduced into the wastewater tank 1 through the liquid inlet pipe 14. The user can add an alkaline solution (such as sodium hydroxide solution, calcium hydroxide solution, etc.) in a suitable proportion into the liquid storage tank 6 according to the amount of wastewater to be treated. After the feeding is completed, the user can neutralize the electrolytic wastewater in the wastewater tank 1. The user can start the motor 2. When the motor 2 is started, the rectangular riser 24 is driven to rotate in the wastewater tank 1 through the transmission rod 22. The transmission rod 22 rotates through the stirring rod 25 to drive each stirring rod 25 to rotate in the wastewater tank 1, and the electrolytic wastewater is stirred to ensure that the alkaline solution is uniformly neutralized in the reaction with the electrolytic wastewater;

[0035] Step 3: In the initial state of the device, the liquid guide port 31 and the bottom liquid outlet trough 23 are in a coincident state, that is, the alkaline solution in the liquid storage tank 6 will enter the conduit connector 36 through the second liquid outlet port 64 and the first liquid outlet port 52, and the alkaline solution will pass through the folded bellows 34, the threaded tube 32 and the movable tube 3 and be discharged from the bottom liquid outlet trough 23, that is, in the initial state, the alkaline solution will first be added to the bottom of the wastewater tank 1, and mixed with the electrolytic wastewater under the stirring of the stirring rod 25 on the rectangular standpipe 24;

[0036] The device drives the rectangular vertical pipe 24 to rotate by the motor 2 driving the transmission rod 22, and the stirring rods 25 on both sides of the rectangular vertical pipe 24 stir the electrolytic wastewater in the wastewater tank 1. At the same time, the liquid outlet 23 at the side end of the rectangular vertical pipe 24 cooperates with the liquid guide port 31 of the movable pipe 3 to realize the addition of alkaline solution from bottom to top, which can improve the mixing uniformity of the alkaline solution and the acidic electrolytic wastewater, make the neutralization reaction more sufficient and efficient, avoid the uneven local acid-base reaction caused by the top pouring type, and facilitate the subsequent accurate processing of metal ion precipitation and other treatment links;

[0037] The device realizes the function of feeding from bottom to top by cooperating with the movable tube 3 and the rectangular vertical tube 24. Initially, the liquid guide port 31 coincides with the bottommost liquid outlet groove 23. As the rectangular vertical tube 24 rotates, the movable tube 3 and its threaded tube 32 rotate in the threaded groove 13 and move upward. The liquid guide port 31 coincides with the liquid outlet grooves 23 at different heights in turn. The alkaline solution is discharged from different heights, which allows the alkaline solution to fully react with the strong acidic area at the bottom first, and then gradually promote the reaction upward. Compared with the traditional pouring feeding, the reaction process can be accurately controlled, so that metal ions such as aluminum ions are precipitated under a more suitable pH gradient, thereby improving the precipitation effect and the quality of metal recovery.

[0038] The device arranges the movable tube 3 in the rectangular vertical tube 24. The rectangular vertical tube 24 and the stirring rod 25 are both made of corrosion-resistant materials. The movable tube 3 is located in the rectangular vertical tube 24 and can play a certain protective role when discharging drugs. While the rectangular vertical tube 24 drives the stirring rod 25 to stir the electrolytic wastewater in the wastewater tank 1, the alkaline solution is discharged from the bottom to the top. Compared with the prior art, the drug discharging pipe with adjustable height is directly inserted into the wastewater tank 1, which does not occupy additional space in the wastewater tank 1 and avoids the phenomenon that the drug discharging pipe may be corroded.

[0039] In the fourth step, when the rectangular stand tube 24 rotates, the movable tube 3 is driven to rotate, and the rotation of the movable tube 3 drives the threaded tube 32 to rotate in the thread groove 13. The threaded tube 32 rotates in the thread groove 13 and gradually moves upward. The upward movement of the threaded tube 32 gradually compresses the folded bellows 34 and the telescopic rod 35. The upward movement of the threaded tube 32 also drives the movable tube 3 to move upward. In the process of the rectangular stand tube 24 continuing to rotate, the movable tube 3 is driven by the threaded tube 32 to gradually move upward, and the liquid guide port 31 on the movable tube 3 moves upward away from the bottom outlet. When the liquid tank 23 is reached, it will continue to move upward, and then gradually overlap with each liquid outlet tank 23 from bottom to top, and the alkaline solution in the liquid storage box 6 will also be discharged from the liquid outlet tanks 23 at different heights, so that in the process of treating electrolytic wastewater, the alkaline solution is added from bottom to top, so that the alkaline solution and the electrolytic wastewater are more evenly integrated, and when the alkaline solution is added, the movable tube 3 rotates with the rectangular standpipe 24, and the alkaline solution is thrown out from the liquid guide port 31 and the liquid outlet tank 23 by inertia, so that the alkaline solution spreads farther in the lateral direction;

[0040] In the process of adding alkaline solution, since the movable tube 3 rotates with the rectangular vertical tube 24, when the rectangular vertical tube 24 drives the stirring rod 25 to rotate and mix, the alkaline solution is thrown out from the liquid guide port 31 and the liquid outlet trough 23 by inertia, and spreads farther in the horizontal direction. Compared with the traditional static feeding method, the horizontal action range of the alkaline solution can be expanded, the mixing speed with the electrolytic wastewater is accelerated, the reaction time is shortened, and the wastewater treatment efficiency is improved;

[0041] The fifth step is that when the annular plate 33 rotates, the two telescopic rods 35 will drive the conduit connector 36 to rotate, the conduit connector 36 will drive the driving gear 37 to rotate, the driving gear 37 will drive the toothed belt 4 to rotate, the toothed belt 4 will drive the driven gear 62 to rotate, the driven gear 62 will drive the connecting rod 61 to rotate, the connecting rod 61 will drive the liquid storage tank 6 to rotate, the liquid storage tank 6 will drive the second liquid outlet 64 to rotate, when the alkaline solution is added to the liquid storage tank 6, only when the second liquid outlet 64 on the liquid storage tank 6 rotates and coincides with the first liquid outlet 52 line, the solution in the liquid storage tank 6 will enter the conduit connector 36, and finally pass through the folded bellows 34, the threaded tube 32 and the movable tube 3, and penetrate from the liquid guide port 31 and the liquid outlet trough 23 side, so as to achieve a small amount of liquid addition multiple times when the alkaline solution is added, and avoid excessive liquid addition at one time, resulting in uneven reaction;

[0042] The device is provided with a liquid storage tank 6 and a tray 5 in coordination. Only when the second liquid outlet 64 of the liquid storage tank 6 coincides with the first liquid outlet 52 of the tray 5, the alkaline solution enters the conduit connector 36 and finally flows out, thereby avoiding problems such as violent local reactions and large fluctuations in pH value caused by a large amount of liquid added at one time, allowing the neutralization reaction to proceed smoothly, which is beneficial to ensuring the stability of water quality when treating wastewater.

Many modifications and variations will be apparent to those of ordinary skill in the art.
