Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a chlor-alkali industrial wastewater purification and treatment device. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources. Wastewater is divided into two types: domestic wastewater and industrial wastewater.

[0003] Wastewater from the chlor-alkali industry is mostly alkaline. When purifying alkaline wastewater, the pH fluctuations are first balanced in an equalization tank. Then, the wastewater is mixed with a neutralizing agent and discharged into a reaction tank for neutralization. However, current technology cannot adjust the amount of neutralizing agent added based on the flow rate of the alkaline wastewater in the pipeline, easily leading to excessive addition, pH imbalance, and increased treatment costs. Therefore, designing a chlor-alkali industry wastewater purification device is a problem we need to solve. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose a chlor-alkali industrial wastewater purification and treatment device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chlor-alkali industrial wastewater purification and treatment device, comprising a water pipe, an outer shell fixedly connected to the outer wall of the water pipe, a liquid tank opened inside the outer shell, a drain pipe connected to one side of the liquid tank, an adjusting component slidably connected inside the drain pipe, a threaded rotating rod connected inside the adjusting component by a thread, the threaded rotating rod being rotatably connected inside the outer shell; and an adding component, which is used to assist workers in quantitatively adding neutralizing agent to alkaline wastewater, the adding component being connected to the water pipe, the outer shell, and the drain pipe.

[0006] In the above technical solution, the added component further includes a sealing plate disposed at the end of the drain pipe away from the liquid tank, and a sliding member is fixedly connected to the side of the sealing plate away from the drain pipe, and the sliding member is slidably connected inside the outer shell.

[0007] In the above technical solution, the outer wall of the sliding member is fixedly connected to a sliding rod, the inside of the sliding rod is slidably connected to a rotating member, and the outer wall of the rotating member is rotatably connected to a connecting block.

[0008] In the above technical solution, a sealing element is further fixedly connected to the bottom of the connecting block. The overall outline of the sealing element is a "U" shape, and the sealing element is rotatably connected inside the water pipe.

[0009] In the above technical solution, a flow guide baffle is fixedly connected to the bottom of the outer shell, and a drain hole is opened at the bottom of the outer shell, with the flow guide baffle disposed at the bottom of the drain hole.

[0010] In the above technical solution, further, a stirring element is rotatably connected inside the water pipe and the outer shell, and a synchronous belt is tensioned on the outer wall of the stirring element; a stirring rod is rotatably connected inside the outer shell and the liquid tank, and the synchronous belt is tensioned on the outer wall of the stirring rod.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By setting up the addition component, the amount of neutralizing agent added can be adjusted according to the flow rate of alkaline wastewater inside the water pipe, avoiding excessive addition of neutralizing agent, which would lead to pH imbalance and affect subsequent treatment of alkaline wastewater, thus avoiding increased treatment costs. At the same time, after the pH value of alkaline wastewater increases, the operator can rotate the threaded rod to gradually disengage the adjusting component from the inside of the drain pipe, increasing the internal space of the drain pipe. After the sealing plate stops sealing the drain pipe, the drainage efficiency of the drain pipe increases simultaneously.

[0013] By incorporating a stirring component, alkaline wastewater and neutralizing agent can be mixed, improving the mixing effect. Furthermore, the neutralizing agent inside the tank can be stirred to prevent sedimentation and stratification, which would negatively impact the neutralization effect on the alkaline wastewater.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 The device shown is a chlor-alkali industrial wastewater purification treatment device, including a water pipe 1, which is fixedly connected to a pipeline between an equalization tank and a reaction tank. A shell 2 is fixedly connected to the outer wall of the water pipe 1. The overall outline of the connection between the water pipe 1 and the shell 2 is a "U" shape. A liquid tank 3 is opened inside the shell 2, and a drain pipe 4 is connected to one side of the liquid tank 3. An adjusting component 5 is slidably connected inside the drain pipe 4. The drain pipe 4, in conjunction with the adjusting component 5, can form an inverted "U" shape. A threaded rotating rod 6 is threadedly connected inside the adjusting component 5. When the pH value of the alkaline wastewater entering the water pipe 1 is too high, the operator can rotate the threaded rotating rod 6, causing the threaded rotating rod 6 to gradually disengage the adjusting component 5 from the inside of the drain pipe 4 through the thread, thereby increasing the efficiency of the drain pipe 4 in discharging the neutralizing agent to adapt to the increased pH value of the alkaline wastewater. The threaded rotating rod 6 is rotatably connected inside the shell 2. An adding component is also included, which assists the operator in quantitatively adding neutralizing agent to the alkaline wastewater. The adding component is connected to the water pipe 1, the shell 2, and the drain pipe 4.

[0021] like Figures 2 to 4 As shown, the added component includes a sealing plate 7 disposed at the end of the drain pipe 4 away from the liquid tank 3. A sliding member 8 is fixedly connected to the side of the sealing plate 7 away from the drain pipe 4. The sliding member 8 is slidably connected inside the outer shell 2. A sliding rod 9 is fixedly connected to the outer wall of the sliding member 8. A rotating member 10 is slidably connected inside the sliding rod 9. A connecting block 11 is rotatably connected to the outer wall of the rotating member 10. A sealing member 12 is fixedly connected to the bottom of the connecting block 11. The overall outline of the sealing member 12 is a "U" shape. The sealing member 12 is rotatably connected inside the water pipe 1. A flow guide baffle 13 is fixedly connected to the bottom of the outer shell 2. A drain hole 14 is opened at the bottom of the outer shell 2. The flow guide baffle 13 is disposed at the bottom of the drain hole 14. A stirring member 15 is rotatably connected inside the water pipe 1 and the outer shell 2. A synchronous belt 16 is tensioned on the outer wall of the stirring member 15. A stirring rod 17 is rotatably connected inside the outer shell 2 and the liquid tank 3. The synchronous belt 16 is tensioned on the outer wall of the stirring rod 17.

[0022] Working principle: When alkaline wastewater flows through water pipe 1, it pushes the seal 12 to rotate. The rotation of seal 12, through connecting block 11, causes rotating component 10 to rotate and descend. Rotating component 10 slides along the inside of slide rod 9 and pulls sliding component 8 along the inner wall of outer casing 2. Sliding component 8 causes sealing plate 7 to gradually stop sealing drain pipe 4, allowing the neutralizing agent inside liquid tank 3 to be discharged through the inverted U-shaped space formed by drain pipe 4 and adjusting component 5. The discharged neutralizing agent is diverted by drain hole 14 and then initially mixed with the alkaline wastewater flowing through water pipe 1 via guide baffle 13. It should be noted that the degree to which seal 12 opens the seal on water pipe 1 is related to the flow rate of alkaline wastewater flowing through water pipe 1, while the degree to which sealing plate 7 opens the seal on drain pipe 4 is related to the sealing pressure. The rotation angle of the seal 12 is related to the flow rate inside the water pipe 1. When the flow rate inside the water pipe 1 increases, the seal 12 is pushed to rotate at an increased angle, gradually stopping the seal on the water pipe 1. The increased rotation angle of the connecting block 11 eventually causes the sealing plate 7 to gradually stop sealing the drain pipe 4, increasing the flow rate of neutralizing agent discharged from the drain pipe 4. When the flow rate inside the water pipe 1 decreases, the alkaline wastewater pushes the seal 12 to rotate at a reduced angle. The seal 12 begins to rotate and reset under its own weight, increasing the sealing area on the water pipe 1. This ultimately increases the sealing area of ​​the sealing plate 7 on the drain pipe 4, reducing the amount of neutralizing agent discharged from the drain pipe 4. This achieves the effect of automatically adjusting the amount of neutralizing agent added according to the flow rate of alkaline wastewater inside the water pipe 1, avoiding excessive addition of neutralizing agent, which would lead to pH imbalance and affect the subsequent treatment of alkaline wastewater, thus avoiding increased treatment costs.

[0023] Furthermore, as the alkaline wastewater initially mixed with the neutralizing agent passes through the agitator 15, the alkaline wastewater and the neutralizing agent push the agitator 15 to rotate and be mixed by the rotating agitator 15, improving the mixing effect of the alkaline wastewater and the neutralizing agent. The rotation of the agitator 15 will drive the agitator rod 17 to rotate through the synchronous belt 16. The rotation of the agitator 15 and the agitator rod 17 will stir and mix the neutralizing agent inside the liquid tank 3, preventing the substances in the neutralizing agent from settling and stratifying inside the liquid tank 3, which would affect the neutralization effect of the neutralizing agent on the alkaline wastewater.
