Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pharmaceutical waste purification treatment, in particular to a waste purification treatment device for pharmaceutical intermediates produced in the synthesis process. BACKGROUND

[0002] The waste produced in the synthesis process of pharmaceutical intermediates generally contains organic substances and other pollutants, and the waste produced in the synthesis process of pharmaceutical intermediates also contains a certain amount of toxic substances or harmful gases.

At the same time, these useful substances are recycled from waste, realizing resource recycling and recycling, and reducing resource waste.

[0003] Compared with the prior art, the stirring rod is generally arranged in the internal preparation treatment tank to continuously stir the raw materials in the internal preparation treatment tank for sufficient mixing. However, the existing method of installing the stirring rod not only occupies part of the internal space of the preparation treatment tank, thereby reducing the effective treatment volume, but also increases the complexity of the equipment, which needs to be cleaned regularly to increase the equipment maintenance cost. At the same time, the stirring rod will be affected by corrosion, wear and tear and other conditions during operation after long-term use, and needs to be regularly maintained and maintained. In addition, the long-term use or frequent vibration of the stirring rod will cause the structure of the equipment to loosen, thereby generating noise during the overall operation of the equipment.

[0017] Compared with the prior art, the beneficial effects of the present application are:

[0018] (1) Compared with the existing technology, the method of setting a stirring rod inside the preparation tank is generally used to continuously stir the raw materials inside the preparation tank for thorough mixing. However, the existing method of installing a stirring rod not only occupies part of the space inside the preparation tank, thereby reducing the effective processing volume, but is also affected by corrosion and wear during operation, requiring regular maintenance and upkeep. This device relies on the drive of the drive motor and the position limit of the limit buckle when rotating to ensure that the wastewater and waste materials input into the preparation tank are thoroughly mixed with the flocculant. Compared with the method of installing a stirring rod, the uniform shaking of the entire preparation tank can save internal space, increase the processing volume, and also avoid the problem of waste material remaining on the surface of the stirring rod when cleaning the inside of the preparation tank later.

[0019] (2) By adjusting the motion between the shaft and the spring, the impact force during the shaking process of the preparation tank is reduced, the vibration and shaking during the operation of the equipment are reduced, the stability of the entire processing tank is improved, and the preparation tank can also be prevented from contacting other existing parts during operation, thereby reducing the noise generated during shaking, avoiding interference to the surrounding environment and personnel during equipment operation, improving the comfort of the working environment, and benefiting the work efficiency and quality of operators.

[0020] (3) Compared with the existing technology of adding flocculants to purify wastewater and waste materials, flocculants can generally only flocculate suspended solids and colloidal substances, causing them to aggregate into larger flocs, which are convenient for subsequent sedimentation or filtration. However, this device ensures that the adsorption plates can normally adsorb metal ions and metal particles in wastewater and waste materials through the coordinated movement of the adsorption plates and baffles. This can make up for and improve the shortcomings of the existing technology in purifying waste materials. By adding the adsorption removal step of the adsorption plates, no other chemical reagents need to be added, thus reducing the use and discharge of chemical pollutants. In addition, permanent magnets have good stability and durability, are not easily affected by the external environment, and are suitable for different water qualities and treatment conditions. Furthermore, permanent magnets have the characteristic of being reusable. After simple cleaning and regeneration, they can be used multiple times, thereby reducing the cost of purifying waste materials.

[0021] (4) relative to the prior art, the way of activated carbon purification treatment of waste gas generated, because the waste gas generally also exist in water vapor, when activated carbon adsorption purification waste gas, water vapor will cause activated carbon surface wet, cause the structure of activated carbon damage and inactivation, thereby reducing the service life of activated carbon, and activated carbon itself has a certain saturation, after a long time, the use of activated carbon itself cannot accurately judge the adsorption capacity, therefore, also will appear activated carbon adsorption instability situation appears, and the device through the dehumidification plate and the adsorption cooperation between the multi-layer purification frame, not only solves the problem of water vapor in waste gas affecting adsorbent, also simultaneously with water vapor recovery to preparation treatment tank inside for recycling again, reduce the humidity and pollutant emissions of waste gas, reduce the influence on the environment, and, multi-layer purification frame at the same time solves the purpose of purifying waste gas, while avoiding the saturation state of itself, ensure the stability of itself, can continuously purify waste gas.

[0038] Specific, relative to the prior art, generally used in the preparation of processing tank 1 inside the setting of the stirring rod, to continue to stir the preparation of processing tank 1 inside the raw materials for adequate mixing, and the existing way to install the stirring rod, not only will occupy part of the space inside the preparation processing tank 1, thereby reducing the effective processing volume, but also in the process of operation by corrosion, wear and tear, etc. The influence needs regular maintenance and maintenance, the device relies on the drive of the drive motor 31, and the position limit of the rotation of the limiting buckle 35, that is, the wastewater and waste materials input into the preparation processing tank 1 and the flocculant can be fully mixed.

[0041] Please refer to Figures 5 to 9 as shown:

[0042] The solid multi-stage purification treatment mechanism 3 comprises a driving motor 31 arranged at the bottom of the preparation treatment tank 1. The outer wall of the output shaft end of the driving motor 31 is fixedly connected with a linkage shaft 32. The end of the linkage shaft 32 away from the driving motor 31 is fixedly connected to the bottom of the preparation treatment tank 1. The outer wall of the linkage shaft 32 is fixedly connected with a connecting shaft 33. The outer wall of the end of the connecting shaft 33 away from the linkage shaft 32 is fixedly connected with a sleeve ring 34. The end of the connecting shaft 33 away from the linkage shaft 32 is provided with a limiting buckle 35. The end of the limiting buckle 35 away from the sleeve ring 34 is fixedly connected to the outer wall of the support frame 13. The middle part of the outer wall of the preparation treatment tank 1 is fixedly connected with a fixed ring 36. The outer wall of the fixed ring 36 is uniformly fixedly connected with an adjusting shaft 37. The end of the adjusting shaft 37 away from the fixed ring 36 is fixedly connected to the side wall of the support frame 13. The outer wall of the adjusting shaft 37 is sleeved with a spring 38. The outer wall of the discharge pipe 12 is sleeved with a placing bin 39. The placing bin 39 is fixedly connected to the inner wall of the preparation treatment tank 1. The inside of the placing bin 39 is fixedly connected with an adsorption piece 310. The outer wall of the discharge pipe 12 is rotatably connected with a rotating ring 311. The outer wall of the rotating ring 311 is uniformly fixedly connected with a baffle 312. The side of the baffle 312 close to each other is provided with an isolation layer 313. The isolation layer 313 is fixedly connected to the inner wall of the preparation treatment tank 1. The bottom plate 314 is installed above the isolation layer 313 and is sleeved on the outer wall of the discharge pipe 12. The linkage shaft 32 is in a curved shape. The linkage shaft 32 is located at the center position of the bottom of the preparation treatment tank 1. The driving motor 31 is located on the side deviating from the axis of the linkage shaft 32. The end of the connecting shaft 33 away from the linkage shaft 32 is fixedly connected with a universal ball. The connecting shaft 33 and the limiting buckle 35 are rotatably connected through the universal ball. The adjusting shaft 37 is in an extendable structure. The ends of the spring 38 are fixedly connected with the fixed ring 36 and the support frame 13, respectively. The adsorption piece 310 is entirely made of permanent magnet material. The overall size of the baffle 312 is adapted to the adsorption piece 310. The baffle 312 is initially attached to the upper surface of the adsorption piece 310. The outer wall of the baffle 312 is fixedly connected with a rotating plate.

[0043] Specifically, compared with the prior art, the waste gas generated by the activated carbon purification treatment, because the waste gas generally also contains water vapor, when the activated carbon adsorbs and purifies the waste gas, the water vapor will cause the activated carbon surface to be wet, causing the structure of the activated carbon to be damaged and deactivated, thereby reducing the service life of the activated carbon, and the activated carbon itself has a certain saturation, after a long time of use, the adsorption capacity of the activated carbon itself cannot be accurately judged, therefore, the activated carbon adsorption is unstable, and the device through the adsorption cooperation between the dehumidification plate 23 and the multi-layer purification frame 26 not only solves the problem of water vapor affecting the adsorbent in the waste gas, but also simultaneously recovers the water vapor to the inside of the preparation treatment tank 1 for reuse, reduces the humidity and pollutant emissions in the waste gas, reduces the impact on the environment, and the multi-layer purification frame 26 simultaneously solves the purpose of purifying waste gas, while avoiding the saturation state of itself, ensuring the stability of itself, and can continuously purify waste gas;

[0044] The following is the complete use steps and working principle of the above embodiment:

[0045] The use process of the device is: when the staff needs to use the equipment to concentrate and purify the generated waste water and waste materials, first, manually rotate the rotating plate of the baffle 312 outer wall, make the baffle 312 and the adsorption piece 310 staggered, then start the drive motor 31 located at the bottom of the preparation treatment tank 1, ensure that its output shaft rotates normally, then concentrate the waste materials and waste water generated during the synthesis of the medicine through the conveying pipe 11 and transport them to the inside of the preparation treatment tank 1, finally, pour the corresponding flocculating agent through the conveying port on one side of the conveying pipe 11, ensure that the subsequent reagent and waste materials and waste water are fully mixed;

[0046] The solid multi-stage purification treatment mechanism 3 is used to ensure the uniform mixing of the raw materials in the preparation treatment tank 1 and the adsorption removal of metal impurities in the waste materials.

[0047] When the staff needs to handle the waste wastewater generated by the synthesis of the medicine, first of all, the driving motor 31 under the equipment needs to be started, and after ensuring that the output shaft end normally rotates, the waste water and waste materials and the flocculating agent are respectively conveyed from the conveying pipe 11 and the conveying port position. Since the outer wall of the output shaft of the driving motor 31 is fixedly connected with the linkage shaft 32, when the output shaft end of the above-mentioned driving motor 31 rotates, the linkage shaft 32 will rotate at the same time, and since the linkage shaft 32 is overall curved, the driving motor 31 is located on one side away from the axis of the linkage shaft 32, so the rotation amplitude of the curved part at one end of the linkage shaft 32 away from the driving motor 31 will be larger. Since the connecting shaft 33 away from one end of the linkage shaft 32 is fixedly connected with the universal ball, and the connecting shaft 33 and the limiting buckle 35 are rotatably connected through the universal ball, and the limiting buckle 35 is overall fixedly connected to the side wall of the support frame 13, the linkage shaft 32 will be specifically limited by the limiting buckle 35 to keep stable during the above-mentioned rotation. And through the driving of the driving motor 31 and the position limitation of the limiting buckle 35, the linkage shaft 32 will specifically swing and rotate uniformly with the output shaft end of the driving motor 31 as the center. Therefore, when the above-mentioned staff conveys the waste materials into the preparation treatment tank 1, the preparation treatment tank 1 will keep the above-mentioned uniform swinging rotation. Compared with the prior art, the preparation treatment tank 1 generally adopts the way of setting a stirring rod in the inside of the preparation treatment tank 1 to continuously stir the raw materials in the inside of the preparation treatment tank 1 for sufficient mixing. However, the existing way of installing the stirring rod not only occupies part of the space in the inside of the preparation treatment tank 1, thereby reducing the effective treatment volume, but also is affected by corrosion, wear and tear and other conditions during operation, and needs regular maintenance and maintenance. The device can ensure that the waste water and waste materials and the flocculating agent input into the inside of the preparation treatment tank 1 are fully mixed by relying on the driving of the driving motor 31 and the position limitation during the rotation of the limiting buckle 35. Compared with the way of installing the stirring rod, the uniform swinging of the whole preparation treatment tank 1 can save the internal space, improve the treatment volume, and also can avoid the problem of waste materials remaining on the surface of the stirring rod when cleaning the inside of the preparation treatment tank 1.

[0048] Since the middle outer wall of the preparation treatment tank 1 is fixedly connected with the fixing ring 36, and the fixing ring 36 is fixedly connected with the support frame 13 through the telescopic adjusting shaft 37, when the preparation treatment tank 1 rotates as a whole, the adjusting shaft 37 is continuously pressed or pulled, and the spring 38 sleeved on the outer wall of the adjusting shaft 37 is compressed or stretched at the same time. Through the movement cooperation between the adjusting shaft 37 and the spring 38, the impact force during the shaking of the preparation treatment tank 1 is reduced, the vibration and shaking during the operation of the equipment are reduced, the stability of the whole treatment cylinder is improved, and the preparation treatment tank 1 can avoid contacting other existing parts during operation, thereby reducing the noise during shaking, avoiding the interference to the surrounding environment and personnel during the operation of the equipment, improving the comfort of the working environment, and being beneficial to the work efficiency and work quality of the operator;

[0049] Since the placing bin 39 is located at the lower position inside the preparation treatment tank 1, and the baffle 312 is initially attached to the upper surface of the adsorption sheet 310, and the outer wall of the baffle 312 is fixedly connected with the rotating plate, before the operator transports the wastewater and flocculating agent into the preparation treatment tank 1, the rotating plate on the outer wall of the baffle 312 is rotated to make the baffle 312 shrink inside the isolation layer 313, so that the isolation layer 313 and the adsorption sheet 310 are in an interlaced state before the waste material is transported. Since the adsorption sheet 310 is entirely made of permanent magnet material, and the adsorption sheet 310 and the transported wastewater are separated only by the bottom plate 314, when the waste material and wastewater are uniformly shaken with the preparation treatment tank 1, the metal ions and metal impurities contained in the waste material and wastewater will be adsorbed by the magnetic attraction of the adsorption sheet 310 after contacting the surface of the bottom plate 314, and then remain on the surface of the bottom plate 314. The overall size of the baffle 312 is adapted to the adsorption sheet 310. Compared with the existing technology of adding flocculating agent to purify wastewater, the flocculating agent can only flocculate suspended matter and colloidal matter to form larger flocculating bodies for subsequent sedimentation or filtration. The movement cooperation of the adsorption sheet 310 and the baffle 312 ensures that the adsorption sheet 310 can normally adsorb metal ions and metal particles in the wastewater, thereby making up for and improving the defects of the existing technology for purifying waste materials. Through the added adsorption and removal step of the adsorption sheet 310, other chemical reagents are not needed, so that the use and emission of chemical pollutants can be reduced. In addition, the permanent magnet has good stability and durability, is not easily affected by the external environment, is suitable for different water quality and treatment conditions, and has the characteristics of being reusable. After simple cleaning and regeneration treatment, it can be used multiple times to reduce the use cost of purifying waste materials;

[0050] When the waste treatment process is completed, the staff first stops the operation of the equipment, and then rotates the rotating plate of the outer wall of the baffle 312 again to make the baffle 312 as a whole return to the original position, at this time the baffle 312 as a whole covers and adheres to the upper side of the adsorption sheet 310, thereby blocking the adsorption force of the adsorption sheet 310 to the iron filings material, at this time the staff can open the top of the equipment to clean and process the iron filings impurities and other solid particle impurities in the inside of the preparation treatment tank 1;

[0051] The waste gas purification and recovery mechanism 2 is used to purify the waste gas generated in the inside of the preparation treatment tank 1, and recover the water in the purified waste gas. When used:

[0052] Because in the process of drug synthesis, various raw materials will involve a series of oxidation reactions, thereby generating some volatile organic substances or gases, these substances will remain in the waste and wastewater, and will be transported together into the inside of the preparation treatment tank 1, and then in the process of purifying the waste and wastewater in the inside of the preparation treatment tank 1, flocculating agent and other reagents need to be added for treatment, some volatile substances in these chemical reagents will also evaporate and react to form waste gas, because the upper side of the preparation treatment tank 1 is symmetrically connected with the branch exhaust pipe 21, therefore, the above-mentioned generated waste gas will flow along the inner wall of the branch exhaust pipe 21 to the inside of the storage cylinder 22, because the dehumidification plate 23 is installed in an inclined manner, and the dehumidification plate 23 is provided with condensation nuclei composed of dust particles, because the surface of the condensation nuclei can attract water molecules, making them gather together to form small droplets, when these small droplets continue to gather, they can grow, until they are no longer in a suspended state, thereby making the water vapor change from a gaseous state to a liquid state, therefore, when the above-mentioned waste gas passes through the position of the dehumidification plate 23, the dehumidification plate 23 will adsorb the water vapor in the waste gas, when enough water vapor is converted into liquid water droplets, it will continue to flow along the inner wall of the connecting pipe 24 into the inside of the preparation treatment tank 1 for water recovery and utilization;

[0053] The outer wall of the exhaust pipe 25 is threadedly connected with the multi-layer purification frame 26, and the multi-layer purification frame 26 is composed of not less than six circular pieces, the surface of each circular piece is provided with a circular hole groove, and the multi-layer purification frame 26 is made of metal material, specifically, a noble metal catalyst such as platinum, palladium, rhodium and the like. Since the exhaust gas is generated during the synthesis of drugs, high-temperature treatment is required during the synthesis of drugs, and therefore the generated exhaust gas is also in a high-temperature state. Therefore, when the subsequent exhaust gas flows to the position of the multi-layer purification frame 26 through the storage cylinder 22, the organic matter and volatile organic compounds VOCs contained in the exhaust gas will be oxidized with the multi-layer purification frame 26 in a high-temperature state, and then converted into harmless carbon dioxide and water. Since the communication pipe 24 and the multi-layer purification frame 26 are connected through the drain pipe 28, the water generated above will flow along the inner wall of the drain pipe 28 and then flow into the inside of the preparation treatment tank 1 through the communication pipe 24, and the purified gas will continue to flow out to the outside of the preparation treatment tank 1 along the inner wall of the treatment cylinder 27. Compared with the prior art, the use of activated carbon to purify and treat the generated exhaust gas, since the exhaust gas generally also contains water vapor, when the activated carbon adsorbs and purifies the exhaust gas, the water vapor will cause the surface of the activated carbon to be wet, causing the structure of the activated carbon to be damaged and deactivated, thereby reducing the service life of the activated carbon, and the activated carbon itself has a certain saturation, after a long time of use, it is difficult to accurately judge the adsorption capacity of the activated carbon itself, therefore, the activated carbon adsorption is unstable. The device solves the problem of water vapor affecting the adsorbent between the dehumidification plate 23 and the multi-layer purification frame 26, and also recycles the water vapor into the preparation treatment tank 1 for reuse, reduces the humidity and pollutant emissions of the exhaust gas, reduces the impact on the environment, and the multi-layer purification frame 26 solves the problem of purifying the exhaust gas, avoids saturation, ensures stability, and can continuously purify the exhaust gas.

[0054] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
