Description

Technical Field

[0001] The invention relates to the technical field of pharmaceutical wastewater treatment, in particular to a multi-stage wastewater treatment device for pharmaceutical intermediate synthesis. Background Art

[0002] Wastewater generated during the synthesis of pharmaceutical intermediates usually has a complex chemical composition, containing a variety of organic solvents, heavy metals, toxic compounds and high concentrations of biochemical oxygen demand (BOD) and chemical oxygen demand (COD). These pollutants pose a serious threat to the environment and human health, and therefore cannot be discharged directly into the environment. The multi-stage wastewater treatment system combines a variety of treatment technologies such as physical, chemical and biological to form a comprehensive treatment process. Each stage of treatment targets specific pollutants or treatment targets, so that various pollutants in the wastewater can be effectively treated. For example, physical treatment can remove suspended matter and sediment; chemical treatment can decompose toxic compounds through redox reactions; biological treatment uses microorganisms to degrade organic matter and reduce the concentration of BOD and COD.

[0003] In the prior art, chemical agents usually require operators to manually measure and add chemical agents into wastewater according to the needs and experience of wastewater treatment. This method relies on manual operation and is easily affected by human factors. It is difficult to accurately control the amount of chemical agents added, resulting in waste of agents or poor treatment effects. Manual addition requires continuous monitoring by operators, which increases labor costs and further increases the risk of operators being exposed to chemicals. It is also impossible to accurately control the amount and time of chemical agents added. Excessive addition of chemical agents will cause waste, increase treatment costs, and cause excessive chemical substances to remain in the wastewater, causing secondary pollution and having a negative impact on the water environment ecosystem; insufficient addition will result in substandard wastewater treatment, requiring repeated treatment or other supplementary measures, resulting in fluctuations in treatment effects, and unable to ensure that the drugs react with harmful substances in the wastewater at the best time and at the most suitable concentration, reducing the treatment efficiency and effect of pharmaceutical wastewater, increasing the risk of secondary pollution, and failing to stably meet the predetermined water quality standards, further increasing the burden on subsequent treatment processes. Improper addition of chemical agents will accelerate corrosion and scaling of equipment, shorten the service life of equipment, and increase maintenance and replacement costs.

The end of the telescopic rod 35 provided with the supporting plate is rotatably connected to the rotating rod 36. The outer circle of the rotating rod 36 is provided with an arc groove 37. The arc groove 37 cooperates with the protrusion 34 to promote the adsorption component 38 to reciprocate and rotate in the filter tube 31, guiding the wastewater to flow to the center of the filter tube 31. The protrusion 34 is slidably adapted to the arc groove 37. The side of the rotating rod 36 away from the telescopic rod 35 is fixedly connected to the adsorption component 38. The adsorption component 38 is slidably connected in the fixed tube 33. The adsorption material such as activated carbon and diatomaceous earth is installed in the adsorption component 38.

[0041] Everything in the above example works like this:

[0042] In the initial state: the medical wastewater after the upper treatment flows into the treatment box 22 through the feed pipe 23, the driving worm 28 is not started, some gears in the driving gear set 211 are not engaged with the eccentric gear, the feed pipe 214 is in the upper center position of the side through groove 26, the telescopic rod 35 is not started, and the protrusion 34 is at the bottom of the arc groove 37.

[0043] The following is the working process of the timing feeding mechanism 2 for feeding chemical agents into the medical wastewater in a timely and quantitative manner to react with harmful substances in the wastewater:

[0044] When in use, the built-in motors of the two driving worms 28 are started to drive the two driving worms 28 to rotate forward and backward respectively. When the driving worms 28 rotate, the two worm wheels 29 are driven to rotate forward and backward respectively through the transmission action. Then, during the forward and backward rotation of the two worm wheels 29, the two transverse bevel gears in the bevel gear set 210 are driven to rotate forward and backward synchronously, thereby driving the vertical wheel in the bevel gear set 210 to rotate counterclockwise. Then, during the counterclockwise rotation of the bevel gear set 210, some gears in the driving gear set 211 are synchronously driven to rotate counterclockwise in the internal gear tube 212, thereby After some gears in the driving gear set 211 rotate 180 degrees, they gradually mesh with the eccentric gear in the driving gear set 211, pushing the eccentric gear in the driving gear set 211 to rotate clockwise, so that when the eccentric gear in the driving gear set 211 rotates clockwise, the inner ring of the internal gear tube 212 is pushed to rotate counterclockwise through meshing transmission, and the counterclockwise rotation of the internal gear tube 212 drives the rotating plate 213 fixedly connected to the internal gear tube 212 to rotate counterclockwise synchronously. Since some gears in the driving gear set 211 are only provided with a quarter-turn gear, this quarter-turn gear can be implemented as There are six gear blocks, so when some gears in the driving gear set 211 rotate one circle, only the eccentric gear in the driving gear set 211 is pushed to rotate ninety degrees. The eccentric gear can be implemented as twenty-four gear blocks, and the inner ring of the internal gear tube 212 is implemented as seventy-two gear blocks. When some gears in the driving gear set 211 rotate one circle, the eccentric gear in the driving gear set 211 is pushed to rotate ninety degrees. Synchronously, the eccentric gear in the driving gear set 211 pushes the six gears meshing with the internal gear tube 212 to rotate thirty degrees, thereby pushing the internal gear tube 212 and the rotating plate 213 to rotate thirty degrees. Under the combined setting of the driving gear set 211 The driving gear set 211 rotates once to push the inner gear tube 212 and the rotating plate 213 to rotate thirty degrees. After rotating six times, the abutting column 216 slides into the groove of the inner concave ring 217, causing the baffle 215 to deflect downward, and the material inside the discharge pipe 214 falls into the wastewater to undergo a chemical reaction. Thereafter, the baffle 215 is reset through the concave arc of the inner concave ring 217 during continuous rotation, restoring the discharge pipe 214 to a closed state. When rotating to the discharge port of the material box 21, the chemical agent inside the material box 21 is refilled into the discharge pipe 214, waiting for the next delivery operation, thereby controlling the delivery time of the chemical agent.

[0045] By setting the timed unloading mechanism 2, with the cooperation of the two driving worms 28, some gears in the driving gear set 211 mesh with the eccentric gears, driving the unloading pipe 214 to rotate intermittently, forming timed unloading, and delivering the quantitative chemical agents packed in the unloading pipe 214 to the treatment box 22 for treatment. The timed and quantitative delivery method can accurately control the dosage and time of the chemical agents, ensuring that the drugs react with the harmful substances in the wastewater at the best time and with the most suitable concentration, thereby improving the treatment efficiency and effect. Accurate delivery reduces the waste of chemicals and avoids excessive or insufficient delivery, thereby reducing the treatment cost and the burden on subsequent treatment processes. Furthermore, the timed and quantitative delivery can realize automatic control, reduce the errors and labor intensity of manual operation, and improve the stability and reliability of the entire wastewater treatment system.

[0046] Please refer to the above working process Figures 1 to 6 .

[0047] The following is the working process of the flow disturbance adsorption mechanism 3 for disturbing the rotation and stirring of the water flow in the wastewater to form a vortex to promote the contact between the wastewater and the adsorption member 38:

[0048] When in use, the two driving worms 28 rotate and drive the timed unloading mechanism 2 to perform timed intermittent unloading, while also causing the two filter tubes 31 fixedly connected to the two driving worms 28 to rotate synchronously. When the two filter tubes 31 rotate forward and backward in the treatment box 22 respectively, the multiple spoiler paddles 32 fixedly connected to the outer circles of the filter tubes 31 are driven to stir the wastewater in the treatment box 22 synchronously, thereby disrupting the internal water flow of the treatment box 22 and mixing the wastewater with the chemical agents spilled by the timed unloading mechanism 2 to a greater extent. Furthermore, when the two filter tubes 31 stir forward and backward to disturb the internal water flow, the pressure at the center of rotation is relatively low, while the pressure at the edge is relatively high when the water flow is rotating and stirring. This pressure difference causes water to flow from the high-pressure area to the low-pressure area, thereby forming a vortex around the center of rotation, thereby forming a vortex at the center of the two filter tubes 31, promoting the circulation of water, and then when the water flows to the two filter tubes 31, the wastewater is initially filtered through the filter holes opened on the filter tubes 31, and the filtered wastewater flows into the filter tubes 31. At this time, the telescopic rod 35 at the bottom of the inner cavity of the filter tube 31 is started by the connected external controller and extends, thereby pushing the rotating rod 36 to move to the end away from the telescopic rod 35, and then The arc groove 37 formed on the outer ring of the rotating rod 36 cooperates with the protrusion 34 to push the rotating rod 36 to rotate while moving, and synchronously drives the adsorption member 38 fixedly connected to the rotating rod 36 to move toward the end away from the telescopic rod 35 while rotating counterclockwise. On the contrary, when the telescopic rod 35 is retracted, the rotating rod 36 drives the adsorption member 38 to rotate clockwise downward, thereby controlling the reciprocating movement of the adsorption member 38 in the filter tube 31, increasing the contact volume between the adsorption member 38 and the wastewater, and improving the adsorption efficiency of harmful substances in the wastewater.

[0049] By setting the turbulent adsorption mechanism 3, under the rotation of the two driving worms 28, the two filter tubes 31 are synchronously driven to rotate forward and reverse in the pharmaceutical wastewater mixed with chemical agents. Under the mutually reverse rotational motion, the laminar flow state of the water flow can be broken, and a more complex flow pattern can be created, so that the wastewater and the treatment agent can fully contact at different levels and regions, reduce the treatment dead corners, ensure that the drugs and pollutants in the wastewater can be evenly distributed, avoid local concentrations that are too high or too low, and promote the chemical agents in the wastewater to be fully contacted and mixed with harmful substances, promote the progress of chemical reactions, and improve the treatment efficiency.

[0050] By driving the worm 28 to synchronously drive the filter tube 31 to rotate and stir, and the filter holes opened on the filter tube 31 and the adsorbent 38 in the filter tube 31, the stirring, filtering and adsorption functions are integrated into one device under multiple settings, saving the space of the treatment system, reducing equipment investment and operating costs. Furthermore, the filter holes on the filter tube 31 perform preliminary filtration on impurities in the wastewater and deposits after chemical reactions during the stirring process to prevent impurities from being adsorbed on the adsorbent 38, thereby affecting the contact between the wastewater and the adsorbent 38. The setting of the filter holes improves the adsorption effect of the adsorbent 38, so that the adsorbent 38 can effectively adsorb harmful substances in the wastewater and reduce the COD chemical oxygen demand value in the wastewater, further improving the purification effect of the wastewater, and all functions are started by the same drive, which is convenient for realizing automatic control and monitoring of the entire treatment process.
