DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 2 A device for recycling concentrated alkaline wastewater from workshop machines comprises a concentrated alkaline storage tank 1, which stores concentrated alkaline wastewater discharged from workshop machines.

[0024] An acid mist tower 2 is provided, wherein two support plates 3 are fixedly connected to the lower end of the acid mist tower 2, a water tank 4 is fixedly connected between the two support plates 3, a liquid flow pipe 5 is fixedly connected to the bottom of the acid mist tower 2, and the liquid flow pipe 5 is directly opposite to the top of the water tank 4. A first water pump 6 is fixedly connected to the side wall of one of the support plates 3 through a bracket, and the input end of the first water pump 6 is connected to the inner wall of the water tank 4, and the output end of the first water pump 6 is connected to the top of the inner wall of the acid mist tower 2 through a first water pipe 7. The first water pump 6 can transport the alkaline solution in the water tank 4 to the first water pipe 7 and then spray it out in the acid mist tower 2, so as to neutralize the acid mist entering the acid mist tower 2. This is a prior art and will not be elaborated here.

[0025] A second water pump 8, the input end of the second water pump 8 is connected to the inner wall of the concentrated alkali storage tank 1, the output end of the second water pump 8 is fixedly connected to a second water pipe 9, the end of the second water pipe 9 away from the second water pump 8 is fixedly connected to a third water pipe 10 through a conveying mechanism, the end of the third water pipe 10 away from the conveying mechanism is connected to the inner wall of the first water pipe 7, a one-way valve is installed in the third water pipe 10, and the one-way valve only allows concentrated alkali wastewater to flow from the third water pipe 10 into the first water pipe 7.

[0026] A pH probe 11 is installed in the water tank 4 to detect the pH value in the water tank 4. The second water pump 8 and the pH probe 11 are electrically connected to an external power supply through a PLC control mechanism.

[0027] Furthermore, the PH probe 11 is used to detect the PH value in the water tank 4. When the PH value in the water tank 4 decreases, it means that the acidity in the water tank 4 increases and the alkaline solution decreases. At this time, the PH probe 11 senses this signal and transmits it to the PLC control mechanism, thereby controlling the second water pump 8 to start, and the concentrated alkaline wastewater in the concentrated alkali storage tank 1 is transported to the acid mist tower 2 through the second water pipe 9, the conveying mechanism, the third water pipe 10 and the first water pipe 7, thereby increasing the alkalinity of the solution entering the acid mist tower 2, increasing the treatment effect of the pickling mist, and realizing the reuse of the concentrated alkaline wastewater generated by the battery workshop machine during operation, avoiding the prior art of adding acidic agents to the concentrated alkaline wastewater for neutralization treatment, which not only leads to high treatment costs using acidic agents, but also leads to manual addition of acidic agents into the concentrated alkaline wastewater, which inevitably contacts high-concentration chemicals and has certain occupational hazards.

[0028] It should be noted that the process of controlling the start and stop of the second water pump 8 through the PLC control mechanism using the signal detected by the PH probe 11 is a common circuit control method and is a prior art, which will not be described in detail here.

[0029] The conveying mechanism includes a conveying cylinder 12 fixedly connected to the inner wall of the concentrated alkali storage tank 1 through a bracket, the inner wall of the conveying cylinder 12 is sealed and rotatably connected to a vertical rod 13, the side wall of the vertical rod 13 is fixedly connected to a spiral blade 14, the side wall of the spiral blade 14 is in contact with the inner wall of the conveying cylinder 12, the second water pipe 9 is connected to the lower part of the inner wall of the conveying cylinder 12, and the third water pipe 10 is connected to the upper part of the inner wall of the conveying cylinder 12.

[0030] The lower end of the vertical rod 13 passes through the bottom of the conveying cylinder 12 and extends to near the bottom of the concentrated alkali storage tank 1 . A plurality of mixing rods 15 are fixedly connected to the side wall of the vertical rod 13 located in the concentrated alkali storage tank 1 .

[0031] Furthermore, when the second water pump 8 is started, the concentrated alkaline wastewater will flow out through the second water pipe 9, the conveying cylinder 12 and the third water pipe 10. Since the side wall of the spiral blade 14 is in contact with the inner wall of the conveying cylinder 12, as the concentrated alkaline wastewater flows upward, the spiral blade 14 will be driven to rotate in the conveying cylinder 12. At this time, the vertical rod 13 will drive multiple mixing rods 15 to rotate to mix the concentrated alkaline wastewater evenly.

[0032] During the battery production process, the acid mist generated enters the acid mist tower 2. At this time, the first water pump 6 can transport the alkaline solution in the water tank 4 to the first water pipe 7 and then spray it out in the acid mist tower 2 to neutralize the acid mist entering the acid mist tower 2. Then the treated water will flow back to the water tank 4 through the liquid flow pipe 5 for continued use.

[0033] When the pH probe 11 detects that the pH value in the water tank 4 decreases, it means that the acidity in the water tank 4 increases and the alkaline solution decreases. At this time, the pH probe 11 senses this signal and transmits it to the PLC control mechanism, thereby controlling the second water pump 8 to start, and the concentrated alkaline wastewater in the concentrated alkali storage tank 1 is transported to the acid mist tower 2 through the second water pipe 9, the conveying cylinder 12, the third water pipe 10 and the first water pipe 7, thereby increasing the alkalinity of the solution entering the acid mist tower 2, increasing the treatment effect of the pickling mist, and realizing the reuse of the concentrated alkaline wastewater generated by the battery workshop machine during operation;

[0034] When the concentrated alkaline wastewater flows from bottom to top in the conveying cylinder 12, the spiral blade 14 is driven to rotate in the conveying cylinder 12 due to the side wall of the spiral blade 14 being in contact with the inner wall of the conveying cylinder 12. At this time, the vertical rod 13 drives multiple mixing rods 15 to rotate to mix the concentrated alkaline wastewater evenly.

[0035] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
