Abstract

This invention discloses a pharmaceutical wastewater dosing treatment device, comprising a treatment tank for storing wastewater and multiple dosing mechanisms installed on the treatment tank. Each dosing mechanism includes a first U-shaped frame and a second U-shaped frame fixedly connected to the treatment tank. The first U-shaped frame is equipped with a supply component for simultaneously supplying gas and liquid pharmaceuticals. The second U-shaped frame is equipped with three temporary storage components that rotate unidirectionally via a unidirectional rotating component. When the temporary storage component rotates to the leftmost position, it connects with the gas supply component, allowing the supplied gas and liquid pharmaceuticals to be stored. During use, this device can increase the dissolved oxygen content by storing liquid oxidizing pharmaceuticals with air under high pressure before uniformly dispensing them into the wastewater treatment tank. This ensures sufficient oxygen supply while minimizing the generation of large air bubbles, thus preventing excessive air bubbles from affecting the actual wastewater treatment effect.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to a pharmaceutical wastewater dosing treatment device. Background Technology

[0002] The pharmaceutical manufacturing process generates a large amount of wastewater with complex composition, high organic content, and poor biodegradability. If this wastewater is discharged directly without effective treatment, it will cause serious harm to the ecological environment and human health.

[0003] Currently, chemical oxidation is a common method for treating pharmaceutical production wastewater. This involves adding oxidizing agents to the wastewater, utilizing their strong oxidizing properties to decompose organic matter and purify the water. Sufficient dissolved oxygen is crucial for the oxidizing agents to fully exert their oxidizing effect, accelerating the oxidation reaction and improving wastewater treatment efficiency.

[0004] However, existing chemical dosing equipment has several problems in the dissolved oxygen stage. Some equipment uses simple aeration to oxygenate the chemical solution. While this increases the dissolved oxygen level, it generates a large number of large bubbles. These large bubbles rise rapidly in the chemical solution and have short contact time with it, resulting in low oxygen utilization and failing to meet the oxygen requirements of the oxidation reaction. Moreover, a large number of large bubbles entering the wastewater treatment tank occupy space, interfering with the thorough mixing of the chemical solution and wastewater, affecting the uniformity and stability of the oxidation reaction, and thus reducing the wastewater treatment effect. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pharmaceutical wastewater dosing treatment device. During use, this device can store liquid oxidizing pharmaceutical solutions with air under high pressure to increase dissolved oxygen levels before uniformly adding them to the wastewater treatment tank. This ensures sufficient oxygen supply without generating excessive large air bubbles, thus preventing air bubbles from affecting the actual wastewater treatment effect.

[0009] Preferably, a movable frame is fixedly connected to the lower end of the third U-shaped frame, and multiple guide columns are fixedly connected between the front and rear inner walls of the treatment pool. The multiple guide columns all penetrate the vertical part of the movable frame and are slidably connected.

[0010] Preferably, a motor is installed at the lower end of the second U-shaped frame, and a synchronous pulley is installed at the upper end of both the output shaft of the motor and the first rotating shaft. The two synchronous pulleys are synchronously connected by a synchronous belt.

[0011] Preferably, the unidirectional rotation assembly includes a support plate fixedly connected to the upper end of the second U-shaped frame, a rotatable second rotating shaft passing through the support plate, a rotating disk fixedly connected to the upper end of the second rotating shaft, a transmission gear fixedly connected to the lower end of the second rotating shaft, and an incomplete gear that cooperates with the transmission gear on the output shaft of the motor.

[0012] Preferably, the temporary storage component includes an accumulation cylinder fixedly connected to the upper end of the rotating disk. A second piston plate that can slide up and down is provided inside the accumulation cylinder. The upper end of the second piston plate is elastically connected to the inner top of the accumulation cylinder by a spring. An abutment rod is fixedly connected to the upper end of the second piston plate, and the upper end of the abutment rod extends to the outside.

[0013] Preferably, a retaining ring is fixedly connected to the upper end of the support plate. The retaining ring is made of rubber. The upper end face of the retaining ring contacts the lower end of the rotating plate. A first through-hole is provided through the left eccentric part of the retaining ring and the support plate. The other end of the second one-way tube is connected to the first through-hole. A second through-hole is provided together at the right eccentric part of the retaining ring and the support plate. A through-hole is provided in the inner bottom of each accumulation cylinder and on the rotating plate. The upper end of the support plate is fixedly connected with multiple connecting plates at equal intervals. The upper ends of the multiple connecting plates are fixedly connected to a top plate. The lower end of the top plate is fixedly connected with an arc-shaped abutment strip. The rear end face of the arc-shaped abutment strip is beveled.

The diversion pipe is connected to the outlet through a release pipe.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. By combining the piston cylinder and the accumulator cylinder, the gas-liquid mixture is compressed and pressurized to increase the dissolved oxygen content of the drug solution and maintain a saturated state, avoiding the generation of large bubbles, prolonging the contact time between oxygen and the drug solution, and improving oxygen utilization. The logic of increasing dissolved oxygen first and then releasing it can avoid the occurrence of many unnecessary interfering bubbles caused by the simultaneous addition of aeration and oxidizing drug solutions.

[0017] 2. The moving frame drives the nozzle to move back and forth and rotate synchronously, spraying the liquid medicine in all directions as fine droplets. At the same time, since the liquid medicine is under high pressure and oxygen-saturated before being added, after the liquid medicine is added, the liquid medicine returns to normal pressure, and oxygen is released to form small bubbles, which carry the liquid medicine to the surface. This further ensures that the liquid medicine is in full contact with the wastewater, improves the uniformity of the oxidation reaction and the wastewater treatment effect. In addition, the small bubbles rise slowly, which allows them to fully contact the wastewater, increasing the dissolved oxygen content of the wastewater and thus increasing the overall oxygen content of the liquid.

[0018] 3. The storage, compression, and release processes are completed in a cycle through three temporary storage components, enabling continuous operation without downtime and improving wastewater treatment efficiency; the flow switch is linked to the solenoid valve to automatically control the release of the liquid and the discharge of gas, avoiding unnecessary gas entry that could affect the reaction.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Reference Figures 1-11 A pharmaceutical wastewater treatment device includes a treatment tank 1 for storing wastewater. The treatment tank 1 is made of corrosion-resistant stainless steel and the inner wall is coated with an anti-corrosion coating (such as polytetrafluoroethylene coating) to prevent the pharmaceutical wastewater from corroding the tank and extend the service life of the equipment. This system also includes multiple dosing mechanisms, all installed on the treatment tank 1. Each dosing mechanism includes a first U-shaped frame 6 and a second U-shaped frame 7 fixedly connected to the treatment tank 1. Both the first U-shaped frame 6 and the second U-shaped frame 7 are welded from channel steel and fixed to the treatment tank 1 with expansion bolts to ensure a secure installation and prevent shaking during operation. The first U-shaped frame 6 is equipped with a supply component for simultaneously supplying gas and liquid chemicals. The supply mechanism includes a third U-shaped frame 25 located inside the treatment tank 1. A first rotating shaft 19 is through-connected to the first U-shaped frame 6. Bearings are installed at the connection of the first U-shaped frame 6 to reduce rotational friction and extend the service life of the shaft. The lower end of the first shaft 19 is rotatably connected to the drive disk 13. The lower end of the drive disk 13 is eccentrically connected to the drive rod 26. The drive rod 26 and the drive disk 13 are welded together, resulting in high connection strength. The horizontal part of the third U-shaped frame 25 has a strip-shaped opening 27 in the left-right direction. The lower end of the drive rod 26 extends into the inside of the strip-shaped opening 27. A roller is provided at the lower end of the drive rod 26. The roller makes rolling contact with the inner wall of the strip-shaped opening 27, reducing frictional resistance during the driving process and ensuring that the third U-shaped frame 25 moves smoothly back and forth. A piston cylinder 8 is installed on the front side of the vertical part at the rear of the first U-shaped frame 6. A first piston plate 33 is slidably connected inside the piston cylinder 8. A sealing ring is fitted on the outer wall of the first piston plate 33 to improve the sealing performance of the piston cylinder 8 and prevent gas and liquid leakage. A fixing rod 34 is fixedly connected to the front side of the first piston plate 33. A vertical plate 9 is fixedly connected to the upper end of the third U-shaped frame 25. The rear side of the vertical plate 9 is fixedly connected to the fixing rod 34. The rear space of the piston cylinder 8 is connected to a first one-way pipe 31 and a second one-way pipe 30. The first one-way pipe 31 is connected to the external oxidizing agent. This part of the agent can improve the reaction effect in a high dissolved oxygen environment. A one-way port 32 is opened on the rear wall of the piston cylinder 8. Both the first one-way pipe 31 and the second one-way pipe 30 are made of corrosion-resistant hoses to prevent the agent from corroding the pipes. The system includes a first one-way pipe 31 for supplying liquid medicine, with a one-way valve inside to ensure that the liquid medicine can only enter the piston cylinder 8 from the outside and prevent backflow. A one-way port 32 is used for supplying air, with a one-way valve inside to ensure that air can only enter the piston cylinder 8 from the outside. A second one-way pipe 30 is used for one-way discharge of gas and liquid, with a one-way valve inside to ensure that the mixed gas and liquid can only be discharged to the temporary storage component, preventing backflow and affecting supply efficiency. All one-way valves are made of corrosion-resistant materials, suitable for the harsh environment of pharmaceutical wastewater treatment, and extend their service life. The lower end of the third U-shaped frame 25 is fixedly connected to a movable frame 2. Multiple guide columns 5 are fixedly connected between the front and rear inner walls of the treatment pool 1. The multiple guide columns 5 all penetrate the vertical part of the movable frame 2 and are slidably connected. The surface of the guide columns 5 is chrome-plated to reduce sliding friction. The lower end of the second U-shaped frame 7 is equipped with a motor 22. The motor 22 is a geared motor with controllable speed, which facilitates the adjustment of the dosing rhythm. The output shaft of the motor 22 and the upper end of the first rotating shaft 19 are both equipped with synchronous pulleys 14. The two synchronous pulleys 14 are synchronously connected by a synchronous belt 15. The synchronous belt 15 is a wear-resistant rubber belt with anti-slip texture on the surface to ensure stable power transmission and avoid slippage.

[0023] Furthermore, the second U-shaped frame 7 is equipped with three temporary storage components that rotate unidirectionally via a single rotating assembly. These three components are evenly spaced to enable continuous operation of gas-liquid mixing, oxygen compression, and drug release, thus improving treatment efficiency. When the temporary storage component rotates to the leftmost position, it connects to the gas supply assembly, storing the supplied gas and drug solution. When it rotates to the right rear, it compresses and temporarily stores the gas, increasing the dissolved oxygen content of the drug solution. When it rotates to the right front, it releases the drug solution and gas. The release of the highly oxygenated solution increases the reaction rate. It should be noted that when the highly oxygenated solution is released, it enters the wastewater, and due to the change to atmospheric pressure, some oxygen will be released. The gas (still in a state of dissolved oxygen saturation) is in the form of small bubbles due to uniform precipitation. The rising of this part of oxygen can carry some of the liquid medicine to the surface, thus allowing the liquid medicine to come into more comprehensive contact with the water. In order to avoid the high temperature generated by compressed air affecting the dissolved oxygen of the liquid medicine, and because the small bubbles rise slowly, they can come into full contact with the wastewater, increasing the dissolved oxygen content of the wastewater and thus increasing the overall oxygen content of the liquid, an active cooling component, such as a cooling fan, can be installed to cool the temporary storage components after compressed gas. The cooling fan is installed at the lower end of the top plate 12, facing the direction of the temporary storage components. The cooling range can cover three temporary storage components to ensure the cooling effect. At the same time, the cooling fan is waterproof and suitable for the humid environment of wastewater treatment. The unidirectional rotation component includes a support plate 10 fixedly connected to the upper end of the second U-shaped frame 7. The support plate 10 is made of stainless steel with a smooth surface. A rotatable second rotating shaft 35 is installed through the support plate 10. A bearing is installed at the connection between the second rotating shaft 35 and the support plate 10 to reduce rotational friction. A rotating disk 23 is fixedly connected to the upper end of the second rotating shaft 35. The rotating disk 23 and the second rotating shaft 35 are welded together for a firm connection. A transmission gear 28 is fixedly connected to the lower end of the second rotating shaft 35. The output shaft of the motor 22 is provided with an incomplete gear 29 that cooperates with the transmission gear 28. The incomplete gear 29 is connected to the output shaft of the motor 22 by a key for easy disassembly and replacement. The tooth profile of the incomplete gear 29 matches that of the transmission gear 28 to ensure smooth transmission. Through the cooperation of the incomplete gear 29 and the transmission gear 28, the rotating disk 23 can rotate intermittently in one direction, so that each temporary storage component can complete the three processes of storage, compression, and release in sequence, ensuring the continuity of operation. It should be noted that initially, the incomplete gear 29 is just engaged with the transmission gear 28. After the motor 22 starts once, in the first quarter revolution, the incomplete gear 29 and the transmission gear 28 are engaged. At this time, the transmission ratio allows the transmission gear 28 to rotate one-third of a revolution (the incomplete gear 29 is a quarter gear, and its number of teeth is one-third of the number of teeth of the transmission gear 28). After the motor 22 completes one-quarter revolution, the transmission gear 28 stops rotating. Furthermore, the rotation of the motor 22 will cause the drive disc 13 to rotate through the transmission of the synchronous pulley 14 and the synchronous belt 15, thereby causing the drive rod 26 to rotate. Figure 4 As shown, during the first quarter turn of rotation, the third U-shaped frame 25 moves forward, and as rotation continues, the third U-shaped frame 25 moves backward. After rotating for another half turn, the third U-shaped frame 25 moves forward again until it finally returns to its initial position (with the last quarter turn of rotation). By using this method, it can be ensured that the accumulation cylinder 24 is in place first, and during the process of bubbling in gas and liquid, the accumulation cylinder 24 is in a stopped state, avoiding interference.

[0024] The temporary storage component includes an accumulation cylinder 24 fixedly connected to the upper end of the rotating disk 23. The accumulation cylinder 24 is made of a thermally conductive material (such as aluminum alloy) to facilitate rapid heat conduction and achieve rapid cooling in conjunction with the cooling component. Inside the accumulation cylinder 24 is a second piston plate 39 that can slide up and down. A sealing ring is fitted on the outer wall of the second piston plate 39 to improve the sealing performance of the accumulation cylinder 24 and ensure a high-pressure environment is formed inside. The upper end of the second piston plate 39 is elastically connected to the inner top of the accumulation cylinder 24 via a spring 40. A stop rod 41 is fixedly connected to the upper end of the second piston plate 39, with its upper end extending to the outside. A stop ring 36 is fixedly connected to the upper end of the support disk 10. The stop ring 36 is made of rubber and has good sealing and cushioning properties. The upper surface of the stop ring 36 contacts the lower end of the rotating disk 23. To ensure the sealing of the bottom of the storage cylinder 24 and prevent gas and liquid leakage, a first through-hole 37 is provided through the left eccentric part of the abutment ring 36 and the support plate 10. The other end of the second one-way pipe 30 is connected to the first through-hole 37. A second through-hole 43 is provided together at the right eccentric part of the abutment ring 36 and the support plate 10. A through-hole 38 is provided on the inner bottom of each storage cylinder 24 and on the rotating plate 23. The diameter of the through-hole 38 matches the first through-hole 37 and the second through-hole 43 to ensure smooth gas and liquid flow. It should be noted that the spring 40 is a spring with a large stiffness coefficient. In addition, the gas is under high pressure. Therefore, when the temporary storage component is rotated to the right front position for release, the liquid release speed is faster, ensuring that the water is under high pressure during the release process, thereby reducing the loss of dissolved oxygen in the transport stage. Multiple connecting plates 11 are fixedly connected at equal intervals to the upper end of the support plate 10. The upper ends of the multiple connecting plates 11 are fixedly connected to a top plate 12. The lower end of the top plate 12 is fixedly connected to an arc-shaped abutment 42. The rear end face of the arc-shaped abutment 42 is all inclined, which facilitates the smooth entry and quick exit of the abutment rod 41 from the abutment range of the arc-shaped abutment 42. When the temporary storage component rotates to the right rear side, the abutment rod 41 contacts the arc-shaped abutment 42. The arc-shaped abutment 42 exerts downward pressure on the abutment rod 41, which drives the second piston plate 39 to move downward, compressing the gas-liquid mixture inside the storage cylinder 24 to form a high-pressure environment (after compression, the spring 40 is still in a compressed state), increasing the dissolved oxygen content of the medicine. When the temporary storage component rotates to the right front side, the abutment rod 41 is released from the pressure of the arc-shaped abutment 42. Under the elastic force of the spring 40, the second piston plate 39 moves downward, quickly pushing the high-oxygen medicine under high pressure out of the storage cylinder 24. The bottom space of the second port 43 is connected to the liquid outlet 44 and the vent 20 respectively. Solenoid valves are installed inside both the liquid outlet 44 and the vent 20. A flow switch 21 for controlling the solenoid valves is set at the bottom of the second port 43. When the flow switch 21 senses that liquid is passing through, the solenoid valve in the liquid outlet 44 opens and the solenoid valve in the vent 20 closes. When the flow switch 21 senses that no liquid is passing through, the solenoid valve in the liquid outlet 44 closes and the solenoid valve in the vent 20 opens. In this way, dissolved oxygen solution can be injected into the wastewater, while excess gas is released to the outside and will not enter the water body. This avoids a large number of large air bubbles entering the wastewater treatment tank, which would occupy the space in the tank and interfere with the full mixing of the solution and the wastewater.

[0025] A diversion assembly is installed at the bottom of the treatment tank 1. This assembly is used to evenly inject the high-oxygenated chemical solution into the bottom space of the treatment tank 1, avoiding excessively high local concentrations of the chemical solution and ensuring thorough mixing between the chemical solution and the wastewater. The diversion assembly includes multiple spray pipes 3 rotatably connected between the inner walls of both sides of the movable frame 2. The spray pipes 3 are made of stainless steel and have multiple spray nozzles on their surface. The spray nozzles are fine, round holes with a diameter controlled between 0.5-1mm, ensuring that the chemical solution is sprayed out as fine droplets, making full contact with the wastewater and preventing clogging of the spray nozzles. Each spray pipe 3 has multiple spray nozzles at its inner bottom, and both ends of each spray pipe 3 are fixedly connected to... The friction wheel 4, which is in contact with the bottom of the treatment tank 1, is made of wear-resistant rubber. When the moving frame 2 moves back and forth, the friction wheel 4 rotates due to friction with the bottom of the treatment tank 1, which drives the spray pipe 3 to rotate, so that the spray nozzle can spray the liquid in all directions, further improving the mixing uniformity. Each spray pipe 3 has a branch pipe 18 rotatably connected to its right end. A rotary joint is installed at the connection between the branch pipe 18 and the spray pipe 3 to ensure that the rotation of the spray pipe 3 does not affect the delivery of the liquid. The other ends of multiple branch pipes 18 are connected to a diversion pipe 16. The diversion pipe 16 is made of corrosion-resistant pipe and is connected to the outlet 44 through the release pipe 17.

[0026] In operation, the wastewater from pharmaceutical production is first stored in treatment tank 1, and motor 22 is started. The output shaft of motor 22 drives synchronous pulley 14 and incomplete gear 29 to rotate synchronously. The two synchronous pulleys 14 are driven by synchronous belt 15 to drive the first rotating shaft 19 to rotate.

[0027] The rotation of the first rotating shaft 19 drives the drive disk 13 to rotate, and the drive rod 26 rotates with the drive disk 13. Its lower end roller rolls in the strip-shaped opening 27, driving the third U-shaped frame 25 to move back and forth along the guide post 5. The moving frame 2 moves synchronously with the third U-shaped frame 25.

[0028] When the third U-shaped frame 25 reciprocates, the vertical plate 9 drives the fixed rod 34 to move synchronously, which in turn drives the first piston plate 33 to slide inside the piston cylinder 8. When the first piston plate 33 moves forward, the external oxidizing agent enters the piston cylinder 8 through the first one-way pipe 31, and the outside air enters the piston cylinder 8 through the one-way port 32; when the first piston plate 33 moves backward, the gas-liquid mixture inside the piston cylinder 8 is discharged through the second one-way pipe 30.

[0029] In the initial state, the incomplete gear 29 meshes with the transmission gear 28. When the motor 22 rotates for the first quarter turn, it drives the transmission gear 28 to rotate for one-third turn, causing a temporary storage component to rotate to the leftmost position and align with the first port 37.

[0030] The motor 22 continues to rotate, the incomplete gear 29 disengages from the transmission gear 28, the rotating disk 23 stops rotating, and the drive disk 13 continues to drive the third U-shaped frame 25 to move backward, continuously supplying the gas-liquid mixture until the accumulation cylinder 24 is full (after completing three-quarters of a rotation, the third U-shaped frame 25 begins to move forward). At this time, the second piston plate 39 moves upward and compresses the spring 40 to accumulate gas and liquid. The gas is located at the top and the liquid is located at the bottom, which facilitates the subsequent segmented release of liquid and gas. Then, the rotation continues until one rotation is completed, and the above structures return to their initial positions. During the second rotation, when the motor 22 drives the incomplete gear 29 to mesh with the transmission gear 28 again, the rotating disk 23 continues to rotate one-third of a turn, causing the accumulation cylinder 24 to rotate to the right rear side. The abutment rod 41 contacts the arc-shaped abutment bar 42, and the arc-shaped abutment bar 42 pushes the abutment rod 41 to move downward, driving the second piston plate 39 to compress the gas-liquid mixture in the accumulation cylinder 24 to increase the dissolved oxygen content. During the third rotation, the accumulation cylinder 24, which has completed pressurization and remained for a period of time, rotates to the right front. The abutment rod 41 is released from the pressure of the arc-shaped abutment bar 42. Under the elastic force of the spring 40, the second piston plate 39 moves downward, pushing the high dissolved oxygen medicine solution through the through port 38 into the second port 43.

[0031] When the flow switch 21 senses the liquid passing through, it controls the solenoid valve of the outlet 44 to open and the solenoid valve of the exhaust port 20 to close. The high dissolved oxygen liquid enters the nozzle 3 through the outlet 44, the release pipe 17, the diversion pipe 16, and the branch pipe 18 in sequence.

[0032] When the moving frame 2 moves back and forth, the friction wheel 4 rubs against the bottom of the treatment tank 1, causing the spray pipe 3 to rotate. The spray pipe 3 sprays the high-oxygenated medicine solution into the treatment tank 1 in the form of fine droplets through the spray nozzle. When the flow switch 21 senses that no liquid is passing through, it controls the solenoid valve of the outlet 44 to close and the solenoid valve of the exhaust port 20 to open, releasing the excess gas in the accumulation cylinder 24 to the outside. When the high-oxygenated medicine solution is released, it enters the wastewater. After becoming at normal pressure, some oxygen will be released (still in a dissolved oxygen saturated state). Because this oxygen is evenly released, it is in the form of small bubbles. The rising of this oxygen can carry some of the medicine solution to the surface, thus allowing the medicine solution to come into more comprehensive contact with the water.

[0033] It should be noted that the three temporary storage components can synchronously and continuously complete the storage, compression, and release processes to achieve continuous operation. At the same time, the moving frame 2 drives the nozzle 3 to move and rotate back and forth to ensure that the high dissolved oxygen solution is evenly distributed and improve the wastewater treatment effect.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
