Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to an industrial wastewater acid-base neutralization device. Background Technology
[0002] Industrial wastewater refers to wastewater generated during industrial production. It has a complex composition and contains a variety of harmful substances, posing a threat to the environment and human health. Direct discharge of untreated industrial wastewater into water bodies will lead to water pollution, disrupt the ecological balance, affect crop growth and aquaculture, and even threaten the safety of human drinking water. Acid-base neutralization uses the chemical reaction between acids and bases to adjust the pH value of wastewater to a neutral range (usually 6-9), thereby reducing its corrosiveness and harm to the environment.
[0003] In current industrial wastewater treatment, acid and alkali solutions are usually mixed in a certain ratio and injected into the wastewater to achieve acid-base neutralization, thereby ensuring that the industrial wastewater meets the discharge standards. However, relying solely on the injection of acid and alkali solutions for reaction, without the addition of stirring and filtration functions, can easily lead to impurities in the wastewater not being fully removed or fully reacted, thus affecting the efficiency and quality of acid-base neutralization. To solve the above problems, we propose an industrial wastewater acid-base neutralization device. Utility Model Content
[0004] The purpose of this invention is to provide an industrial wastewater acid-base neutralization device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial wastewater acid-base neutralization device, comprising a treatment tank, a filter tank fixedly connected to the top of the treatment tank, a water inlet on the top of the filter tank, a first solenoid valve on the outside of the water inlet, an acid tank and an alkali tank fixedly connected to one side of the treatment tank, connecting pipes fixedly connected between the acid tank and the alkali tank and the treatment tank, both connecting pipes communicating with the interior of the treatment tank, one end of each connecting pipe extending into the interior of the acid tank and the alkali tank respectively, a material inlet on the top of each acid tank and the alkali tank, a second solenoid valve on the outside of each material inlet, a stirring blade rotatably connected between the inner walls of the treatment tank, a stirring assembly on the top of the treatment tank for driving the stirring blade to rotate, a discharge port on the bottom of the treatment tank, and a pH sensor on one side inside the treatment tank.

The outer side of the stirring shaft is fixedly connected to the stirring blades, and the top end of the stirring shaft extends to the top of the processing tank and is fixedly connected to a worm gear.
[0010] As a further preferred embodiment of this technical solution, a mounting plate and a support plate are fixedly connected to the top of the processing box, and a worm gear is rotatably connected between the mounting plate and the support plate, the worm gear meshing with a worm wheel.

[0012] This utility model provides an acid-base neutralization device for industrial wastewater, which has the following beneficial effects:
[0013] (1) This utility model controls the inflow and flow rate of industrial wastewater through the first solenoid valve outside the water inlet. Then the wastewater flows through the first filter frame inside the first chute to effectively filter out impurities and ensure the purity of the wastewater to facilitate a full reaction. Next, the second solenoid valves outside the two inlet ports control the injection volume of acid and alkali respectively. Then, the two feed pumps transport acid and alkali to the treatment tank along the corresponding two connecting pipes. During this process, the stirring component drives the stirring blade to rotate, fully stirring the wastewater and acid and alkali solutions to achieve a full acid-base neutralization reaction, thereby achieving a highly efficient and full acid-base neutralization reaction and significantly improving the efficiency and quality of acid-base neutralization of industrial wastewater.
[0014] (2) The present invention facilitates the separation of acid-base neutralized wastewater from the precipitate formed by the reaction through the second filter frame inside the second chute, further ensuring that the wastewater meets the discharge standards. At the same time, the cooperation between the first chute and the second chute and the first filter frame and the second filter frame respectively facilitates the treatment of filtered impurities and precipitates, thereby improving the overall effect of the acid-base neutralization device.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, an industrial wastewater acid-base neutralization device includes a treatment tank 1. A filter tank 2 is fixedly connected to the top of the treatment tank 1. A water inlet 3 is opened on the top of the filter tank 2. A first solenoid valve 4 is arranged on the outside of the water inlet 3. An acid tank 12 and an alkali tank 13 are fixedly connected to one side of the treatment tank 1. A connecting pipe 16 is fixedly connected between the acid tank 12 and the alkali tank 13 and the treatment tank 1. Both connecting pipes 16 communicate with the interior of the treatment tank 1. One end of each connecting pipe 16 extends into the interior of the acid tank 12 and the alkali tank 13, respectively. A material inlet 14 is opened on the top of the acid tank 12 and the alkali tank 13. A second solenoid valve 15 is arranged on the outside of each material inlet 14. A stirring blade 18 is rotatably connected between the inner walls of the treatment tank 1. A stirring assembly is provided on the top of the treatment tank 1 to drive the stirring blade 18 to rotate. A discharge port 20 is provided at the bottom of the treatment tank 1. A pH sensor 19 is provided on one side inside the treatment tank 1. A first chute 21 is provided on one side of the filter tank 2. A first filter frame 5 is slidably connected between the inner walls of the first chute 21. A second chute 22 is provided on one side of the treatment tank 1. A second filter frame 11 is slidably connected between the inner walls of the second chute 22. Feed pumps 23 are fixedly installed between the inner walls of the acid tank 12 and the alkali tank 13. The output ends of the two feed pumps 23 are fixedly connected to the extension ends of the two connecting pipes 16, respectively.
[0022] When neutralizing industrial wastewater with acids and alkalis, the device is first connected to an external power source and powered on. Then, the controller activates the first solenoid valve 4 and two second solenoid valves 15. Next, the industrial wastewater is injected into the filter tank 2 through the inlet 3. Simultaneously, the first solenoid valve 4 controls the injection volume and flow rate of the industrial wastewater. The wastewater then flows through the first filter frame 5 inside the first chute 21 (the bottom of the first filter frame 5 is equipped with a filter plate, specifically made of polypropylene material to ensure the corrosion resistance and filtration performance of the first filter frame 5), thus filtering impurities from the industrial wastewater. The filtered industrial wastewater then flows into the treatment tank 1. A pH sensor 19 detects the acidity or alkalinity of the industrial wastewater. At the same time, acid and alkali solutions are injected into the acid tank 12 and alkali tank 13 respectively through the two inlet ports 14. The two second solenoid valves 15 then activate... The injection volumes of acid and alkali are controlled separately. Then, based on the acidity and alkalinity of the industrial wastewater, the acid and alkali are injected into the treatment tank 1 through two feed pumps 23 corresponding to two connecting pipes 16 according to the neutralization requirements. Subsequently, the stirring assembly drives the stirring blades 18 to rotate between the inner walls of the treatment tank 1 to achieve an efficient acid-alkali neutralization reaction between the acid and alkali and the industrial wastewater. Then, the precipitate produced by the reaction is filtered out from the neutralized industrial wastewater through the second filter frame 11 inside the second chute 22 (the bottom of the second filter frame 11 is equipped with a filter plate, specifically made of polypropylene material to ensure the corrosion resistance and filtration performance of the second filter frame 11). At the same time, the pH value sensor 19 is used again to detect the acidity and alkalinity of the neutralized industrial wastewater to ensure that the neutralized industrial wastewater meets the discharge standards. Finally, it is safely discharged through the discharge port 20.
[0023] After the industrial wastewater has been neutralized and discharged, the first filter frame 5 and the second filter frame 11 can be removed from the inside of the first chute 21 and the second chute 22 respectively, so as to clean the filtered impurities and sediments, thereby improving the effectiveness of the industrial wastewater acid-base neutralization device.
[0024] like Figures 1-4 As shown, the stirring assembly includes a stirring shaft 17, which is rotatably connected to the top of the inner side of the processing tank 1. The outer side of the stirring shaft 17 is fixedly connected to the stirring blade 18. The top end of the stirring shaft 17 extends to the top of the processing tank 1 and is fixedly connected to a worm gear 6. The top of the processing tank 1 is fixedly connected to a mounting plate 7 and a support plate 8. A worm 9 is rotatably connected between the mounting plate 7 and the support plate 8. The worm 9 meshes with the worm gear 6. A stirring motor 10 is fixedly installed on one side of the mounting plate 7. The output end of the stirring motor 10 passes through the mounting plate 7 and is fixedly connected to the worm 9.
[0025] The stirring motor 10 drives the worm gear 9 to rotate between the mounting plate 7 and the support plate 8. Through the meshing of the worm gear 9 and the worm wheel 6, the stirring shaft 17 drives the stirring blades 18 to rotate between the inner walls of the treatment tank 1, thereby improving the efficiency of acid-base neutralization of industrial wastewater.
[0026] This utility model provides an industrial wastewater acid-base neutralization device. The specific working principle is as follows: When neutralizing industrial wastewater, the device is first connected to an external power source and powered on. Then, the controller activates the first solenoid valve 4 and two second solenoid valves 15. Next, industrial wastewater is injected into the filter tank 2 through the inlet 3. Simultaneously, the first solenoid valve 4 controls the injection volume and flow rate of the industrial wastewater. The wastewater then flows through the first filter frame 5 inside the first chute 21 to filter impurities. The filtered wastewater then flows into the treatment tank 1. A pH sensor 19 detects the acidity or alkalinity of the wastewater. At the same time, acid and alkali solutions are injected into the acid tank 12 and alkali tank 13 respectively through two inlet ports 14. The two second solenoid valves 15 control the acid and alkali solutions respectively. The injection volume of the liquid is determined, and then, based on the acidity or alkalinity of the industrial wastewater, the acid and alkali solutions are injected into the treatment tank 1 via two feed pumps 23 corresponding to two connecting pipes 16 according to the neutralization requirements. Subsequently, the stirring motor 10 drives the worm gear 9 to rotate between the mounting plate 7 and the support plate 8, and through the meshing of the worm gear 9 and the worm wheel 6, the stirring shaft 17 drives the stirring blades 18 to rotate between the inner walls of the treatment tank 1, so as to achieve an efficient acid-alkali neutralization reaction between the acid and alkali solutions and the industrial wastewater. Then, the precipitate produced by the reaction is filtered out from the neutralized industrial wastewater through the second filter frame 11 inside the second chute 22. At the same time, the pH value sensor 19 is used again to detect the acidity or alkalinity of the neutralized industrial wastewater to ensure that the neutralized industrial wastewater meets the discharge standards. Finally, it is safely discharged through the discharge port 20.
[0027] After the industrial wastewater has been neutralized and discharged, the first filter frame 5 and the second filter frame 11 can be removed from the inside of the first chute 21 and the second chute 22 respectively, so as to clean the filtered impurities and sediments, thereby completing the use of the industrial wastewater acid-base neutralization device.
