[0014] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example
[0016] Please see Figure 1-3 In pharmaceutical production, the resulting waste residue typically contains unreacted raw materials, solvents, catalysts, and acidic / alkaline substances. Direct discharge or simple treatment not only wastes resources but may also cause environmental pollution. Traditional pharmaceutical waste residue treatment technologies share the following common drawbacks:
[0017] Low efficiency of liquid-solid separation: Traditional methods rely on gravity sedimentation or single mechanical extrusion, which makes it difficult to completely separate the liquid components in the waste residue, resulting in a large load on subsequent processing, and the residual active substances in the liquid are prone to causing secondary pollution.
[0018] Incomplete neutralization reaction: The mixing of solid waste residue and neutralizing agent is usually carried out by static stirring or manual turning, resulting in poor mixing uniformity, low reaction efficiency, and difficulty in meeting emission standards; the liquid neutralization process lacks dynamic control, and the phenomenon of excessive or insufficient neutralizing agent occurs frequently.
[0019] Therefore, this application protects a waste treatment device for pharmaceutical production. The device involves pouring pharmaceutical waste into the inner side of a funnel-shaped guide block 5, which collects the waste into the inner side of a T-shaped feeding pipe 4. An inclined drive motor 8 rotates, causing the inclined guide shaft 6 on its drive end to rotate. This rotation drives the T-shaped feeding pipe 4 and the guide vanes 7 inside the inclined guide roller 3. The rotating guide vanes 7 steadily lift and lower the waste along the inclined guide roller 3, while simultaneously guiding the liquid in the waste to the inner side of the filter tank 1 via the inclined guide roller 3. The waste material is guided to the inside of the extrusion mixing box by the inclined flow-guiding arc plate 9. The angle drive motor 12 runs, driving the bevel gear 13 on the drive end of the angle drive motor 12 to rotate. The bevel gear 13 drives the bevel rack 14 that meshes with it, and the bevel rack 14 drives the rotating disk 10 on it. This causes the rotating disk 10 to rotate stably and horizontally inside the annular groove 11 on the filter support 2. The rotating disk 10 drives the lifting and limiting shaft tube 15 and the extrusion lifting and limiting shaft tube 15 on it. The stirring on the rotating disk 10... The drive unit operates, driving the mixing gearbox 20 on the drive end of the mixing drive unit. The mixing gearbox 20 drives the lifting and limiting shaft 16 inside, which in turn drives the mixing blades 19. The rotation of the mixing blades 19 mixes the contents inside the extrusion mixing chamber, thus first mixing the solid waste with the neutralized liquid. Then, the rotation of the rotating disk 10 moves the extrusion lifting and limiting shaft tube 15 to the top of the extrusion mixing chamber. The operation of the stretching winch drives the stretching hydraulic chuck on it, which... The lifting and striking extrusion block and the extrusion extrusion block on it are driven to rise and fall stably. The tension hydraulic chuck is released, so that the lifting and striking extrusion block rises and falls stably along the inner side of the extrusion lifting limit shaft tube 15. The waste is extruded and struck by gravity. At the same time, the stirring drive machine drives the stirring and mixing shaft inside the filter tank 1. The stirring and mixing shaft drives the stirring blades 19 on it to rotate. The liquid inside the raw material box is diverted to the inner side of the filter tank 1 through the flow valve. The stirring and mixing shaft drives the stirring blades 19 on it to mix the liquid.
[0020] In summary, during the waste feeding stage, the material is gathered by the trumpet-shaped guide block 5 and vertically conveyed through the T-shaped feeding pipe 4, with the inclined design of the inclined guide roller 3 achieving directional flow. Then, in the liquid-solid separation stage, the inclined drive motor 8 drives the guide blades 7 to spiral upwards, using centrifugal force to separate the liquid into the filter tank 1. Simultaneously, the mechanical compression between the inner wall of the roller and the gap between the blades accelerates liquid seepage. The separated solids are then guided into the extrusion mixing box via the inclined guide arc plate 9. In the solid neutralization stage, the angle drive motor 12 drives the rotating disk 10 to rotate horizontally, combined with the stirring drive motor driving the lifting limit shaft 1. 6. Rotation: The combined motion of revolution and rotation enhances mixing efficiency, and the height of the stirring blades 19 is adjusted via hydraulic push rods to accommodate different filling volumes. In the extrusion molding stage, the rotating disc 10 is positioned above the extrusion mixing chamber, and a stretching winch releases the gravitational impact (kinetic acceleration approximately 1.2-1.8 m / s²) of the lifting and striking extrusion blocks to achieve efficient compression, with a hydraulic chuck locking to prevent rebound. In the liquid neutralization stage, the amount of neutralizing agent is controlled by a flow valve, combined with turbulent mixing (Reynolds number Re>4000) from the stirring shaft to ensure sufficient reaction and achieve dynamic pH adjustment (error ±3%). Key technology additions include the addition of a generator set to the inclined guide shaft 6 to recover rotational kinetic energy (theoretical efficiency 18-22%), an intelligent control module (liquid level sensor, pressure sensor, and online pH monitoring), and emission standard adaptation. Process optimization suggestions include adding a pretreatment crushing device (particle size <5mm), adopting variable frequency drive technology to reduce energy consumption by 30%, and installing an automatic lubrication system to maintain the bearings of the rotating disc 10. This device achieves a 60-70% reduction in waste volume and allows for the reuse of the neutralized liquid through a triple process of mechanical separation, dynamic mixing, and gravity extrusion, meeting the requirements of a circular economy. In actual operation, attention should be paid to blade wear (check every 500 hours) and the accuracy calibration of the flow valve.
[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
