Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical wastewater technology, and more specifically, to an adsorption tank for pharmaceutical wastewater purification and treatment. Background Technology

[0002] Pharmaceutical wastewater refers to wastewater discharged during the pharmaceutical production process. Due to the diversity of drug varieties and different production processes, the composition of the discharged wastewater varies. The main types of wastewater include wastewater from antibiotics, synthetic pharmaceuticals, traditional Chinese medicine preparations, and washing water from various pharmaceutical formulations. The purification of pharmaceutical wastewater requires the use of adsorption tanks. The adsorption materials inside these tanks have abundant pore structures and a large specific surface area, enabling them to adsorb conventional organic matter and novel pollutants such as antibiotics through physical adsorption, chemical adsorption, or ion exchange. This reduces the concentration of pollutants in the wastewater and minimizes their harm to the environment.

[0003] A search revealed a Chinese patent application with patent number CN219585864U, which discloses an activated carbon adsorption tank for pharmaceutical wastewater. The tank has a cover plate fixedly installed on its upper surface and an adsorption device installed inside the tank.

[0004] Although the aforementioned patent utilizes a drive motor mounted on the surface of the cover plate to rotate the stirring shaft and stir the stirring blades during operation, thereby agitating the pharmaceutical wastewater entering from the inlet pipe and preventing impurities in the wastewater from settling and clogging the filter holes, and the irregular holes penetrating the surface of the stirring blades can improve the stirring efficiency, the following shortcomings still exist in actual use: 1. The stirring method is singular, resulting in insufficient and uneven stirring of the wastewater within the tank. For some pollutants with higher density and easy sedimentation, they may accumulate at the bottom of the tank and cannot be effectively stirred up to participate in the adsorption process; 2. When dealing with some pollutants with higher density and easy sedimentation, it is easy to cause equipment blockage, which limits the overall processing efficiency of the equipment and makes it impossible to quickly and efficiently treat pharmaceutical wastewater. In large-scale wastewater treatment scenarios, this will increase treatment costs and time costs.

[0005] Therefore, there is an urgent need for an adsorption tank for pharmaceutical wastewater purification to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an adsorption tank for the purification and treatment of pharmaceutical wastewater, so as to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] An adsorption tank for purifying pharmaceutical wastewater includes a tank body, wherein symmetrically distributed fixed columns are fixedly connected to the inner wall of the tank body, and a drive gear disc is fixedly connected to the end of each fixed column away from the tank body. The tank also includes:

[0009] The retaining posts are symmetrically and fixedly connected to the inner wall of the tank.

[0010] A stirring assembly includes a cross rotatably connected to the inner wall of a tank, a symmetrically distributed rotating frame rotatably connected to the inner wall of the cross, a stirring frame fixedly connected to the inner wall of the rotating frame, symmetrically distributed stirring blades fixedly connected to the outer wall of the stirring frame, and a driven gear fixedly connected to the top wall of the rotating frame, the outer wall of the driven gear meshing with the outer wall of the drive gear disc.

[0011] A cleaning component is disposed on the outer wall of the cross, and the cleaning component cooperates with the stirring component.

[0012] As a preferred technical solution of this application, the cleaning component includes a rotating column fixedly connected to the outer wall of the cross, and two to three sets of extension columns that are threadedly connected to each other are provided at the end of the rotating column away from the cross. The extension column at the top is threadedly connected to the rotating column, and a uniformly distributed fixing plate is fixedly connected to the outer wall of the extension column. A uniformly distributed scraping tool is fixedly connected to the outer wall of the fixing plate.

[0013] As a preferred technical solution of this application, the top wall of the tank is fixedly connected with a uniformly distributed mounting bracket, and a drive motor is fixedly connected to the end of the mounting bracket away from the tank, and the output end of the drive motor is fixedly connected to the cross.

[0014] As a preferred technical solution of this application, an adsorption plate is snapped between the symmetrically positioned pins, and the outer wall of the adsorption plate is provided with uniformly distributed filter holes.

[0015] As a preferred technical solution of this application, a water inlet pipe is fixedly connected to the top wall of the tank, a valve is fixedly connected to the end of the water inlet pipe away from the tank, and a sealing flange is fixedly connected to the end of the valve away from the water inlet pipe.

[0016] As a preferred technical solution of this application, the outer wall of the tank is detachably connected to a bottom plate, the top wall of the bottom plate is fixedly connected to a rotating shaft seat, and the rotating shaft seat is fixedly connected to a rotating column. A drain pipe is fixedly connected to the outer wall of the bottom plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. The drive motor drives the cross to rotate, and the rotating frame on the cross can also rotate relative to it. This allows the stirring blades to have both revolution and rotation motions, creating a complex three-dimensional flow field in the tank. The wastewater in each area can be fully stirred, ensuring that pollutants are evenly dispersed and in full contact with the adsorption material. The revolution motion causes the wastewater to flow rapidly in the radial direction of the tank, while the rotation enhances the tangential disturbance of the wastewater around the stirring blades. The wastewater in both the center and edge areas of the tank can be effectively stirred, improving the uniformity of stirring and preventing the sedimentation of substances in the wastewater. This solves the problem of the single stirring method in the existing technology, which makes the stirring of wastewater in the tank insufficient and uneven. For some pollutants with high density and easy sedimentation, they may accumulate at the bottom of the tank and cannot be effectively stirred up to participate in the adsorption process.

[0020] 2. By evenly distributing the scrapers on the fixed plate and extension column, a multi-layer cleaning structure is formed. As the rotating column rotates, the scrapers of different layers can cover different height areas of the adsorption plate, effectively cleaning the adsorption plate. Due to the flexibility and friction of the scrapers, they can scrape off impurities, dirt, and biofilms that may form on the surface of the adsorption plate, thereby achieving the purpose of cleaning the adsorption plate. This extends the cycle of disassembling and cleaning the adsorption plate, reduces time and processing costs, and solves the problem in existing technologies that easily cause equipment blockage when dealing with some high-density pollutants that are prone to settling. This limits the overall processing efficiency of the equipment and makes it impossible to quickly and efficiently treat pharmaceutical wastewater. In large-scale wastewater treatment scenarios, this increases the processing cost and time cost. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figure 1-5 As shown, the adsorption tank for pharmaceutical wastewater purification proposed in this embodiment includes a tank body 1, with symmetrically distributed fixed columns 11 fixedly connected to the inner wall of the tank body 1. A drive gear disc 12 is fixedly connected to the end of the fixed column 11 away from the tank body 1. The tank body 1 also includes:

[0030] The locking posts 9 are symmetrically and fixedly connected to the inner wall of the tank body 1;

[0031] The stirring assembly includes a cross 13 rotatably connected to the inner wall of the tank 1. Symmetrically distributed rotating frames 14 are rotatably connected to the inner wall of the cross 13. A stirring frame 16 is fixedly connected to the inner wall of the rotating frame 14. Symmetrically distributed stirring blades 17 are fixedly connected to the outer wall of the stirring frame 16. A driven gear 15 is fixedly connected to the top wall of the rotating frame 14, and the outer wall of the driven gear 15 meshes with the outer wall of the drive gear 12. When the cross 13 rotates, since the drive gear 12 remains stationary, the driven gear 17 rotates through the meshing action between the drive gear 12 and the driven gear 15. The wheel 15 drives the rotating frame 14 to rotate within the cross 13. The stirring frame 16, which is fixedly connected to the inner wall of the rotating frame 14, and the stirring blade 17, which is fixedly connected to the outer wall of the stirring frame 16, also revolve and rotate accordingly. During the rotation, the stirring blade 17 continuously cuts and stirs the wastewater, causing the wastewater to form a complex water flow. On the one hand, it turns the wastewater at the bottom of the tank 1 upward to ensure that wastewater at different depths can be fully stirred. On the other hand, it makes the wastewater flow quickly in the horizontal direction, increasing the contact opportunity and contact effect between the wastewater and the adsorption plate 10.

[0032] The cleaning component is located on the outer wall of the cross 13, and the cleaning component cooperates with the stirring component.

[0033] like Figure 2-3As shown, in a preferred embodiment, based on the above method, the cleaning component further includes a rotating column 18 fixedly connected to the outer wall of the cross 13. Two to three sets of extension columns 19 are threadedly connected to each other at the end of the rotating column 18 away from the cross 13. The top extension column 19 is threadedly connected to the rotating column 18. Evenly distributed fixing plates 20 are fixedly connected to the outer wall of the extension column 19. Evenly distributed scraping bristles 21 are fixedly connected to the outer wall of the fixing plates 20. When the cross 13 rotates, the rotating column 18 rotates synchronously. The scraping bristles 21 have a certain degree of flexibility and friction, enabling them to scrape off impurities, dirt, biofilm, and other substances adsorbed or attached to the surface of the adsorption plate 10 during wastewater treatment, keeping the surface of the adsorption plate 10 clean and ensuring its adsorption performance is not affected. Simultaneously, it prevents impurities from clogging the filter holes 23 of the adsorption plate 10, ensuring the continuous and efficient operation of the wastewater treatment process. The extension columns 19 can be disassembled by interlocking threads.

[0034] The adsorption plate is a plate-shaped adsorption device formed by filling an adsorption material such as activated carbon or granular carbon into a rectangular mesh rigid frame and wrapping it with a water-permeable and air-permeable material such as non-woven fabric or gauze. The rigid frame can be made of plastic or metal.

[0035] like Figure 4 As shown, in a preferred embodiment, based on the above method, the top wall of the tank 1 is further provided with a uniformly distributed mounting bracket 3. The end of the mounting bracket 3 away from the tank 1 is fixedly connected to a drive motor 4, and the output end of the drive motor 4 is fixedly connected to the cross 13. The cross 13 is driven by the drive motor 4.

[0036] like Figure 2 As shown, in a preferred embodiment, based on the above method, an adsorption plate 10 is further connected between the symmetrical locking posts 9. The outer wall of the adsorption plate 10 is provided with uniformly distributed filter holes 23. The adsorption plate 10 is connected to the locking posts 9 so as to facilitate disassembly and centralized cleaning.

[0037] like Figure 1 As shown, in a preferred embodiment, based on the above method, a water inlet pipe 5 is fixedly connected to the top wall of the tank 1. A valve 6 is fixedly connected to the end of the water inlet pipe 5 away from the tank 1. A sealing flange 7 is fixedly connected to the end of the valve 6 away from the water inlet pipe 5. The wastewater entering the tank 1 is controlled by the valve 6, so that the wastewater can be stopped from entering the tank 1 when cleaning the tank 1.

[0038] like Figure 5As shown, in a preferred embodiment, based on the above method, the tank body 1 is further provided with a bottom plate 2 detachably connected to the outer wall, a rotating shaft seat 22 is fixedly connected to the top wall of the bottom plate 2, and the rotating shaft seat 22 is fixedly connected to the rotating column 18. A drain pipe 8 is fixedly connected to the outer wall of the bottom plate 2, and the treated wastewater is discharged through the drain pipe 8.

[0039] Specifically, in use, the adsorption tank for the purification and treatment of pharmaceutical wastewater is as follows: the output end of the drive motor 4 is fixedly connected to the cross 13. When the drive motor 4 starts, its output power is directly transmitted to the cross 13, causing the cross 13 to rotate on the inner wall of the tank body 1. When the cross 13 rotates, since the drive gear 12 is fixed, through the meshing action between the drive gear 12 and the driven gear 15, the driven gear 15 will drive the rotating frame 14 to rotate within the cross 13. The stirring frame 16 fixedly connected to the inner wall of the rotating frame 14 and the stirring blades 17 fixedly connected to the outer wall of the stirring frame 16 also revolve and rotate accordingly. During the rotation, the stirring blades 17 continuously cut and agitate the wastewater, causing the wastewater to form a complex water flow. On the one hand, it turns the wastewater at the bottom of the tank 1 upward to ensure that wastewater at different depths can be fully stirred. On the other hand, it makes the wastewater flow quickly in the horizontal direction, enhancing the contact opportunity and contact effect between the wastewater and the adsorption plate 10. When the cross 13 rotates, the rotating column 18 also rotates synchronously. The scraper 21 has a certain degree of flexibility and friction, which can scrape off the impurities, dirt, biofilm and other substances adsorbed or attached to the surface of the adsorption plate 10 during the wastewater treatment process, keeping the surface of the adsorption plate 10 clean and ensuring that its adsorption performance is not affected. At the same time, it prevents impurities from clogging the filter holes 23 of the adsorption plate 10, ensuring the continuous and efficient operation of the wastewater treatment process. Its extension column 19 can be disassembled by means of mutual threads.

[0040] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
