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

[0002] Pharmaceutical processing is the production process of chemical drugs, consisting of two parts: raw material production and pharmaceutical preparation production. Raw materials are the material basis for drug production, but they must be processed into pharmaceutical preparations suitable for consumption to become drugs. The pharmaceutical industry also includes the production of traditional Chinese medicine. The pharmaceutical processing process generates wastewater, which can cause environmental pollution if not treated in time.

[0003] Existing wastewater treatment methods for pharmaceutical processing are relatively simple and cannot treat the harmful chemical components in the wastewater. This results in a large amount of chemical substances being discharged into the wastewater, which will pollute the environment. At the same time, the inner walls of existing treatment equipment will accumulate a large amount of pollutants after long-term use, making cleaning and maintenance very troublesome. Summary of the Invention

[0004] The purpose of this utility model is to provide a pharmaceutical processing wastewater purification device to solve the problems mentioned in the background art, such as the simple treatment of wastewater generated by existing pharmaceutical processing, which cannot treat the harmful chemical components in the wastewater, resulting in a large amount of chemical substances in the discharged wastewater, which will cause environmental pollution. At the same time, the inner wall of the existing treatment device will be covered with a large amount of pollutants after long-term use, making the cleaning and maintenance process very troublesome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical processing wastewater purification device, comprising a sedimentation tank, wherein plug-in seats are provided on both inner walls of the sedimentation tank, and filter screens are movably plugged into the inner side of the plug-in seats; a reaction chamber is provided on the top of the sedimentation tank, a stirring shaft is provided on the inner side of the reaction chamber, and stirring paddles are arranged around the outer side of the stirring shaft; cleaning brushes are provided at the outer ends of the stirring paddles; a motor is provided through the top of the stirring shaft and inserted into the reaction chamber; and reagent tanks are provided on both sides of the reaction chamber.

The outlet end of each delivery pump is provided with an extraction pipe, and the inlet end of the delivery pump is connected to the sedimentation tank through a pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This pharmaceutical processing wastewater purification device, during daily use, introduces the wastewater to be treated into the reaction tank. By opening the control valve, the flocculant and neutralizing agent in the reagent tank are introduced into the reaction tank, which coagulates the impurities in the wastewater into lumps. At the same time, the internal chemical substances are neutralized and eliminated in real time. Then, the impurities are removed in real time through the filter screen. Finally, the wastewater is settled in the sedimentation tank to avoid excessive residual chemical substances and impurities, which would cause pollution to the environment if directly discharged.

[0013] This pharmaceutical processing wastewater purification device, during daily use, uses a motor to drive the stirring shaft and stirring paddle to rotate, thereby achieving real-time stirring and mixing of the pharmaceuticals and wastewater, resulting in a better and more complete overall reaction. At the same time, when cleaning is required, a cleaning brush can be used to clean the deposits on the inner wall, making the cleaning effect better and more efficient. Attached Figure Description

The motor 18 drives the stirring shaft 20 and the stirring paddle 19 to rotate, so as to achieve real-time stirring and mixing of the reagent and wastewater, making the overall reaction effect better and more complete. The impurities in the wastewater are coagulated into lumps, and the internal chemical substances are neutralized and eliminated in real time. Then, the impurities are removed in real time by the filter screen 21. Finally, the sedimentation tank 10 is used for sedimentation treatment to avoid excessive internal chemical substances and impurities, which would cause pollution to the environment if discharged directly. At the same time, when cleaning is required, the cleaning brush 23 can be used to clean the inner wall to avoid excessive internal wall deposits affecting the pharmaceutical effect.
