Description

Technical Field

[0001] This utility model relates to the field of ethanol distillation technology for pharmaceutical wastewater, and more particularly to an ethanol distillation apparatus for pharmaceutical wastewater. Background Technology

[0002] Pharmaceutical wastewater is a type of industrial wastewater generated during the production process of the pharmaceutical industry. It poses a significant potential hazard to the environment and human health. However, some of the raw materials in pharmaceutical wastewater can be recycled. Ethanol distillation is a process that utilizes the difference in boiling points between ethanol and other substances (especially water) to purify or separate ethanol through vaporization and condensation, thereby recycling ethanol from pharmaceutical wastewater.

[0003] Chinese Patent Publication No. CN219539464U, relating to the field of gellan gum production technology, discloses an ethanol recovery distillation device, including a raw material tank. One end of the raw material tank is equipped with a suction pipe, and one end of the suction pipe is equipped with a suction pump. One end of the suction pump is equipped with a conveying pipe, and the outer surface of the conveying pipe is equipped with a diversion pipe. This utility model has the following advantages and effects: The heating layer inside the distillation tank is activated to raise the temperature, heating the first and second vaporization tanks. An external motor is activated, causing the rotating shaft to drive the rotating rod to stir inside the first and second vaporization tanks. Through the gradual heating of the distillation tank and the cooperation of the rotating shaft and rod, the ethanol quickly reaches its boiling point and is fully vaporized, increasing the flow rate of vaporized ethanol. Furthermore, the diversion pipe divides and conveys the raw liquid, allowing the first and second vaporization tanks to simultaneously distill and vaporize equal amounts of ethanol, thus achieving simultaneous batch vaporization and separation of ethanol.

[0004] For existing ethanol distillation devices for pharmaceutical wastewater, in practical use, the vertical orientation of the distillation column limits the efficiency and flexibility of the distillation and fluid separation process. Furthermore, pharmaceutical wastewater cannot effectively absorb metal impurities during treatment, and the efficiency of separating precipitates from the water source is low, affecting the overall treatment efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an ethanol distillation device for pharmaceutical wastewater, which solves the problems in the prior art where the vertical orientation of the distillation column limits the efficiency and flexibility of the distillation and fluid separation process and results in low purification efficiency of pharmaceutical wastewater.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An ethanol distillation device for pharmaceutical wastewater includes a treatment tank. A top plate is bolted to the top of the treatment tank, and a motor is fixedly connected to the top of the top plate. The output shaft of the motor is driven by a magnetic rod, and a stirring rod is fixedly connected to the surface of the magnetic rod. A feed pipe is connected to the top of the top plate, and a drain pipe is connected to the surface of the treatment tank. The treatment tank is equipped with a partition mechanism. One end of the drain pipe is connected to a filter, and the other end of the filter is connected to an inclined tower. Several cross-distributed mass transfer plates are fixedly connected inside the inclined tower.

[0007] Preferably, the separation mechanism includes two first cylinders fixedly connected inside the processing box. The output shaft of the first cylinder is fixedly connected to a lifting plate, and a second cylinder is rotatably connected to the lifting plate. A separation plate is rotatably connected to the surface of the lifting plate, and the separation plate is rotatably connected to the output shaft of the second cylinder and the surface of the separation plate.

[0008] Preferably, the surfaces of the two partition plates are fixedly connected with buffer pads, and the sides of the two partition plates that are close to each other have semi-circular grooves.

[0011] Preferably, the surface of the tilted tower is fixedly connected with a support rod in the shape of an "I".

[0012] This utility model has the following beneficial effects: When distilling ethanol from pharmaceutical wastewater, the wastewater can be treated in a treatment tank first. During the treatment process, magnetic rods can effectively absorb metallic impurities in the wastewater. When discharging precipitates and purified water, a convenient separator can separate the precipitates and purified water, allowing the purified water to be discharged separately, improving efficiency while ensuring the purification effect.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-5An ethanol distillation device for pharmaceutical wastewater includes a treatment tank 1, which is a convenient container for treating and recycling pharmaceutical wastewater. A top plate 2 is bolted to the top of the treatment tank 1, and a motor 3 is fixedly connected to the top of the top plate 2. A magnetic rod 4 is driven by the output shaft of the motor 3, and a stirring rod 5 is fixedly connected to the surface of the magnetic rod 4. A feed pipe 6 connects to the top of the top plate 2. When pharmaceutical wastewater needs to be treated, the wastewater and purifying agent are first introduced into the treatment tank 1 through the feed pipe 6 on the top plate 2. Then, the motor 3 is started, and the output shaft of the motor 3... The output shaft drives the magnetic rod 4 to rotate inside the treatment box 1. The rotation of the magnetic rod 4 drives the stirring rod 5 to stir the wastewater and purifying agent, improving the efficiency of the purifying agent in treating the wastewater and making it easier to purify and recycle the wastewater. During the purification process, metal components are adsorbed by the magnetic rod 4, making it easier to absorb and process metal waste. When it is necessary to clean the metal waste on the magnetic rod 4, the bolts can be loosened to remove the top plate 2, allowing the magnetic rod 4 to be taken out for cleaning. The surface of the treatment box 1 is connected to a drain pipe 7, and the interior of the treatment box 1 is equipped with... After the purifying agent has been agitated to more efficiently purify the pharmaceutical wastewater, the separation mechanism 8 stops the motor 3, allowing the wastewater to settle. The sediment settles at the bottom of the treatment tank 1. Then, the separation mechanism 8 is activated, using a separator plate 804 to separate the sediment from the purified water. Afterward, the drain pipe 7 on the side of the treatment tank 1 is opened, allowing the purified water above to drain away, thus separating the sediment from the purified water for further treatment. One end of the drain pipe 7 is connected to a filter 9, which is existing technology. The other end of the filter 9 is connected to an inclined tower 1. After being filtered once by filter 9, the purified water enters the interior of the inclined tower 10 from below. Several mass transfer plates 11 are fixedly connected inside the inclined tower 10 in a cross-shaped distribution. The mass transfer plates 11 are structures in the tower equipment that realize the mass transfer process between the gas and liquid phases. Several small holes are opened on the surface of the mass transfer plates 11. The gas rises through the small holes and forms a bubble layer with the liquid on the plate for mass transfer. The inclined tower 10 is inclined to the ground, and the mass transfer plates 11 are parallel to the ground, which increases the area of ​​the mass transfer plates 11 and can improve the capacity and efficiency of the distillation and fluid separation process.

[0018] Furthermore, the separation mechanism 8 includes two first cylinders 801 fixedly connected inside the treatment tank 1. The output shaft of the first cylinder 801 is fixedly connected to a lifting plate 802. A second cylinder 803 is rotatably connected to the lifting plate 802. A separation plate 804 is rotatably connected to the surface of the lifting plate 802. The output shaft of the separation plate 804 and the second cylinder 803 are rotatably connected to the surface of the separation plate 804. When it is necessary to separate the sediment from the purified wastewater, the first cylinder 801 can be started first. The output shaft of the first cylinder 801 descends, which can cause the lifting plate 802 to descend and move to the interface between the sediment and the purified water. Then, the second cylinder 803 is rotated, which can push the separation plate 804 out and rotate it. The second cylinder 803 also rotates on the surface of the lifting plate 802 during the rotation of the separation plate 804 until the two separation plates 804 can clamp the magnetic rod 4, so that the separation plate 804 cooperates with the lifting plate 802 to separate the sediment from the purified water.

[0019] Preferably, buffer pads 805 are fixedly connected to the surfaces of the two partition plates 804. Each of the two partition plates 804 has a semi-circular groove on the side that is close to each other. After the two partition plates 804 are rotated and fitted together, they can be buffered by the buffer pads 805 to protect the partition plates 804 from damage to the magnetic rod 4, so that the magnetic rod 4 can be used for a long time.

[0020] Preferably, the bottom of the treatment tank 1 is arc-shaped, and the bottom of the treatment tank 1 is connected to the discharge pipe 12. When purifying wastewater, the inner wall of the bottom of the treatment tank 1 is smooth, and the arc-shaped bottom of the treatment tank 1 facilitates the flow of water and the treatment of sediment. When draining and discharging, the separation mechanism 8 is activated first to separate the sediment from the purified water, and then the drain pipe 7 is opened so that the purified water located above can be discharged from the side of the drain pipe 7 and enter the filter 9 for filtration again before being sent to the inclined tower 10. Then the discharge pipe 12 is opened so that the sediment located at the bottom leaves the treatment tank 1, and then the next treatment of pharmaceutical wastewater is carried out.

[0021] Preferably, a heater 13 is fixedly connected to the bottom of the inclined tower 10, and a discharge pipe 14 is connected to the top of the inclined tower 10. The bottom of the inclined tower 10 needs to be lower than the height of the filter 9 to facilitate the entry of purified water into the interior of the inclined tower 10. Then, the heater 13 is activated to heat the purified water, causing the ethanol in the purified water to evaporate. Then, the ethanol enters the interior of the inclined tower 10 and is mass transferred by the mass transfer plate 11 to achieve more efficient separation and purification. After that, the vapor can be discharged from the top of the inclined tower 10 through the discharge pipe 14 and enter the next processing step.

[0022] Preferably, the surface of the tilting tower 10 is fixedly connected with a support rod 15 in the shape of an "I". When the tilting tower 10 is supported, only one side of the tilting tower 10 needs to be supported to make it stable, which facilitates the stable installation of the tilting tower 10.

[0023] In summary: When it is necessary to distill ethanol from pharmaceutical wastewater, the wastewater must first be treated. After treatment, the purified water is sent into the inclined tower 10 for distillation. During treatment, the wastewater and purifying agent are first fed into the treatment tank 1 through the feed pipe 6 on the top plate 2. Then, the motor 3 is started, which drives the magnetic rod 4 to rotate inside the treatment tank 1. The rotation of the magnetic rod 4 drives the stirring rod 5 to rotate as well. The stirring rod 5 mixes the purifying agent and wastewater together, improving the purification efficiency. The magnetic rod 4 can also attract and adhere metal waste in the wastewater, ensuring the purification effect. After a period of time, the motor 3 is stopped to allow the wastewater to settle. Then, the first cylinder 801 is started, causing the lifting plate 802 to descend. Then, the second cylinder 803 is started, causing the partition plate 804 to rotate. The two partition plates 804 clamp the magnetic rod 4 through the buffer pad 805, thereby separating the sediment that has settled inside the treatment tank 1 from the purifying agent. The purified water is separated, and then the drain pipe 7 is opened to allow the purified water at the top to leave the treatment tank 1 and enter the interior of the filter 9. The filter 9 then enters the interior of the inclined tower 10. The filter 9 needs to be higher than the bottom of the inclined tower 10 to facilitate the entry of the purified water. The discharge pipe 12 is then opened to discharge the sediment. Afterwards, the pipe entering the inclined tower 10 is closed, and then the heater 13 is started to heat the wastewater entering the inclined tower 10. The ethanol in the wastewater evaporates, and the vapor undergoes mass transfer through the mass transfer plate 11 inside the inclined tower 10. The tilt of the inclined tower 10 and the non-tilting nature of the mass transfer plate 11 increase the effective area of ​​the mass transfer plate 11, improving the capacity and efficiency of the distillation and fluid separation process. The vapor is then discharged through the discharge pipe 14 for condensation. The support rod 15 ensures the stable operation of the inclined tower 10, reduces structural requirements, and simplifies installation and maintenance. Through this structure, the purification effect and efficiency are guaranteed, and the efficiency and effect of distillation are improved.
