Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, specifically a pharmaceutical wastewater treatment device. Background Technology

[0002] The pharmaceutical manufacturing process generates wastewater containing a large number of harmful substances. If discharged directly, it will seriously pollute the environment, so wastewater treatment is necessary.

[0003] A biopharmaceutical wastewater treatment device disclosed in CN219314593U includes a treatment tank. A drive motor is fixedly installed at the top of the treatment tank, and a first transmission rod extending to the top of the inner cavity of the treatment tank is provided at the bottom of the drive motor. A second transmission rod located in the middle of the inner cavity of the treatment tank is fixedly installed at the bottom of the first transmission rod, and a scraper is fixedly installed on the outer surface of the second transmission rod. The radius of the trajectory circle formed by the outer surface of the scraper is equal to the inner diameter of the treatment tank and contacts its inner wall.

[0004] The aforementioned document describes the design of the second transmission rod and its upper structure. During the rotation of the scraper, it simultaneously stirs the pharmaceutical wastewater and additives within the treatment tank while also scraping the inner wall of the tank in real time, preventing scale formation and effectively improving the stability of the wastewater treatment device. However, the wastewater also contains particulate impurities. After treatment with chemicals, these impurities are difficult to separate and discharge. Furthermore, pharmaceutical wastewater often has a strong, pungent odor, which pollutes the environment upon discharge. Therefore, we propose a pharmaceutical wastewater treatment device to address these issues. Utility Model Content

[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] Please see Figure 1-5This utility model provides a technical solution: a pharmaceutical wastewater treatment device, including a treatment tank 1, a drive motor 4, and a supply tank 11. An inlet pipe 2 is connected to the upper end of the treatment tank 1, and an outlet pipe 3 is connected to the lower side of the treatment tank 1. The drive motor 4 is installed at the bottom of the treatment tank 1, and a connecting shaft 5 is fixed to the output end of the drive motor 4. A stirring plate 6 is uniformly fixed to the surface of the connecting shaft 5. A vertical rod 7 is fixed below the stirring plate 6 above the connecting shaft 5. The stirring plate 6 is inclined, and the lower end surface of the stirring plate 6... The filter screen 17 is tapered and attached to the upper surface of the filter screen 17, which facilitates the filtration and isolation of wastewater. A connecting rod 8 is fixed to the bottom of the connecting shaft 5, and a connecting ring 9 is fixed to the surface of the connecting rod 8. An opening 10 is provided on the surface of the connecting ring 9. The outer diameter of the connecting ring 9 matches the inner diameter of the treatment tank 1, and the area of ​​the opening 10 on the surface of the connecting ring 9 is equal to the area of ​​the lower end of the discharge pipe 23, so that the fragrance inside the medicine tank 22 can be discharged into the treatment tank 1 from the discharge pipe 23.

[0024] Please see Figure 1-5 A filter screen 17 is fixed to the bottom inner side of the treatment tank 1. A sealing door 18 is rotatably connected to the surface of the treatment tank 1. Connecting ear frames 19 are fixed to the upper and lower ends of the side of the sealing door 18. The connecting ear frames 19 on the side of the sealing door 18 are fixedly connected to the positioning rod 20 by fastening nuts 21, which facilitates the opening of the sealing door 18 so that the impurities isolated inside the filter screen 17 can be discharged. A positioning rod 20 corresponding to the connecting ear frames 19 is fixed to the surface of the treatment tank 1. A medicine supply box 22 is installed on the lower side of the other side of the surface of the treatment tank 1. The lower end of the medicine supply box 22 is connected to the treatment tank 1 through a feeding pipe 23. The feeding pipe 23 is inclined in the middle to facilitate the supply of medicine to the box. The fragrance inside the tank 22 is discharged. A supply tank 11 is fixed on one side of the surface of the treatment tank 1, and a water pump 12 is fixed above the supply tank 11. One end of the water pump 12 is connected to a water guide pipe 13, and the other side of the water pump 12 is connected to a water suction pipe 14 that runs through the inside of the supply tank 11. The inner end of the water guide pipe 13 is connected to a water collection ring 15 fixed above the treatment tank 1, so that the neutralizing solution inside the supply tank 11 can be introduced into the treatment tank 1 through the water suction pipe 14 and the water guide pipe 13. Water spray heads 16 are evenly installed on the inner surface of the water collection ring 15, and the water spray heads 16 are set at an angle, so that the water spray heads 16 on the surface of the water collection ring 15 can discharge the neutralizing solution into the treatment tank 1.

[0025] Working principle: First, during use, the water pump 12 above the supply tank 11 is turned on, allowing the water pump 12 to guide the wastewater neutralizing solution inside the supply tank 11 into the water collection ring 15 through the water suction pipe 14 and the water guide pipe 13. This facilitates the water spray head 16 to discharge water into the treatment tank 1. Then, by turning on the drive motor 4, the stirring plate 6 on the surface of the connecting shaft 5 and the vertical rod 7 agitate the internal wastewater neutralization. The filter screen 17 fixed inside the treatment tank 1 can effectively isolate impurities in the wastewater. The upper end of the filter screen 17 is in contact with the lower end of the stirring plate 6, which can effectively prevent the filter screen 17 from clogging during filtration. The impurities isolated inside the filter screen 17 can be removed by opening the sealing door 18.

[0026] After the wastewater is separated and falls down through the filter screen 17, the fragrance inside the medicine supply tank 22 will be discharged into the treatment tank 1 through the discharge pipe 23. When the connecting shaft 5 rotates, it will rotate inside the treatment tank 1 through the connecting ring 9 at the end of the connecting rod 8, so that the opening 10 on the surface of the connecting ring 9 can be connected with the discharge pipe 23, allowing the fragrance to enter the bottom of the treatment tank 1 and mix with the wastewater, which can help mask the irritating odor in the liquid and avoid the problem of the wastewater being too irritating and polluting the environment.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
