Description

Technical Field

[0001] This utility model relates to the field of chemical wastewater treatment technology, specifically a wastewater treatment device for manufacturing chemical products. Background Technology

[0002] Wastewater treatment equipment used in the manufacture of chemical products is specifically designed to treat wastewater containing high concentrations of organic matter, heavy metals, or toxic substances generated during chemical production.

[0022] 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.

[0023] like Figures 1 to 5 As shown, the present invention provides a wastewater treatment device for manufacturing chemical products, including a treatment device 1 and a mixing mechanism. The mixing mechanism includes a mixing cylinder 2 fixedly connected to the top of the treatment device 1. The bottom outlet of the mixing cylinder 2 is connected to the top inlet of the treatment device 1. A support frame 3 is fixedly connected to the top of the mixing cylinder 2. A motor 4 is fixedly connected to the surface of the support frame 3. A transmission shaft 5 is fixedly connected to the bottom output shaft of the motor 4. The bottom end of the transmission shaft 5 extends into the interior of the mixing cylinder 2 and is fixedly connected to a stirring blade 6. A jet mixing mechanism is provided on the top of the treatment device 1.

[0024] refer toFigure 5 The spray mixing mechanism includes four nozzles 7 fixedly connected to the inner wall of the mixing cylinder 2. A connecting pipe 8 is connected to the outside of the nozzles 7. A water pump 9 is connected to the right end of the connecting pipe 8. A water inlet pipe 10 is connected to the top of the water pump 9. A liquid tank 11 is connected to the right end of the water inlet pipe 10. A maintenance assembly is provided on the top of the treatment equipment 1.

[0025] As a technical optimization of this utility model, a spray mixing mechanism is set up to uniformly spray the liquid medicine into the liquid inside the mixing cylinder 2 through four nozzles 7, which increases the contact area between the liquid medicine and the liquid, and helps to improve the uniformity and speed of mixing. The water pump 9 provides power for the delivery of the liquid medicine, ensuring that the liquid medicine can stably enter the mixing cylinder 2, further optimizing the mixing effect and improving the processing performance of the entire device.

[0026] refer to Figure 3 The maintenance assembly includes a fixing ring 12 fixedly connected to the surface of the mixing drum 2. A maintenance disc 13 is fixedly connected to the left side of the fixing ring 12 by bolts. A washer 14 is movably connected to the right side of the maintenance disc 13. A top ring 15 is fixedly connected to the right side of the washer 14. The surface of the top ring 15 is fixedly connected to the inner wall of the mixing drum 2.

[0027] As a technical optimization of this utility model, by setting up maintenance components, it is easier to inspect and maintain the interior of the mixing cylinder 2. This improves the maintainability of the device, reduces maintenance costs and difficulty, and extends the service life of the device.

[0028] refer to Figure 2 The front and rear sides of the mixing cylinder 2 are fixedly connected with reinforcing plates 16, and the bottom of the reinforcing plates 16 is fixedly connected to the top of the processing equipment 1.

[0029] As a technical optimization of this utility model, the connection strength and stability between the mixing cylinder 2 and the processing equipment 1 are enhanced by setting the reinforcing plate 16. During the operation of the device, the rotation of the stirring blade 6 will generate certain vibrations and forces. The reinforcing plate 16 can effectively reduce the impact of such vibrations on the connection parts, prevent the mixing cylinder 2 from shaking or loosening, ensure the normal operation of the device, and improve the reliability and safety of the device.

[0030] refer to Figure 1 A ladder 17 is fixedly connected to the left side of the processing device 1, which facilitates the inspection and maintenance of the entire device.

[0031] As a technical optimization of this utility model, the addition of ladder 17 provides operators with a convenient passage, allowing them to easily reach the top of the device to inspect, maintain, and operate components such as the mixing cylinder 2, the jet mixing mechanism, and the maintenance components. This significantly improves work efficiency, reduces the time and effort required for operators to move between the ground and the top of the device, and also facilitates the timely detection and resolution of problems that arise during device operation.

[0032] refer to Figure 5 The top of the liquid medicine tank 11 is provided with an arc corner 18, which can prevent sharp edges from scratching the operator.

[0033] As a technical optimization of this utility model, by setting an 18° arc angle, the existence of sharp edges and corners is effectively avoided, preventing operators from being scratched during operation. This design fully considers the safety of operators, reduces safety risks during operation, reflects the humanized and safe design of the device, and protects the health of operators.

[0034] The working principle and usage process of this utility model: This device is mainly used for treating chemical wastewater. During the treatment process, the liquid to be treated first enters the mixing cylinder 2 through the top inlet. Simultaneously, the water pump 9 starts, drawing the chemical solution from the chemical tank 11. The chemical solution passes through the inlet pipe 10 and connecting pipe 8, and finally sprays out from the four nozzles 7 on the inner wall of the mixing cylinder 2. The impact force of the water jet initially mixes with the liquid inside the mixing cylinder 2. At this time, the motor 4 drives the drive shaft 5 and the stirring blade 6 to rotate, fully stirring and mixing the liquid and chemical solution inside the mixing cylinder 2 (at this time, wastewater and chemical solution are flowing into the treatment equipment 1 through the inside of the mixing cylinder 2), ensuring uniform fusion (chemical spraying and stirring are performed simultaneously). The mixed liquid enters the treatment equipment 1 from the bottom outlet of the mixing cylinder 2 for further treatment. Thus, wastewater flows into the mixing cylinder 2 from the outside, is simultaneously mixed and stirred, and then flows into the treatment equipment 1, eliminating the separate stirring and mixing step, increasing the additional processing time for mixing the chemical solution and wastewater, and increasing treatment efficiency. When the device requires maintenance, the maintenance panel 13 can be removed via the maintenance components for internal inspection and maintenance. Operators can also easily reach the top of the device via the ladder 17. The arc angle 18 at the top of the chemical tank 11 ensures the safety of operators. This design avoids the decrease in treatment efficiency caused by low wastewater-chemical mixing efficiency, making it easy to use.

[0035] In summary, when this utility model is used, the stirring and mixing mechanism, the spraying and mixing mechanism and their maintenance components enable the wastewater and the chemical solution to mix synchronously during the process of flowing into the treatment equipment 1, avoiding the decrease in treatment efficiency caused by the low mixing efficiency of wastewater and chemical solution, thus giving it the advantage of being easy to use.
