Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a crystallization separation device for high-salt wastewater. Background Technology

[0002] High-salinity wastewater refers to industrial wastewater containing a large amount of dissolved salts. These salts mainly originate from various industrial production processes such as chemical, leather, metallurgy, printing and dyeing, pharmaceutical, and seafood processing. Due to its high salt content, high-salinity wastewater is characterized by high density, high viscosity, and strong corrosiveness. It also inhibits or kills microorganisms, making conventional biological treatment methods difficult to implement effectively. If discharged directly without proper treatment, it will not only cause serious damage to the ecological environment and affect the survival of aquatic organisms, but may also pollute the soil and groundwater. Therefore, its treatment and disposal have always been a difficult and important issue in the field of industrial environmental protection. High-salinity wastewater crystallization separation devices are advanced environmental protection equipment specifically designed for treating industrial wastewater with extremely high salt content.

[0003] Traditional high-salinity wastewater crystallization separation devices may lack effective stirring mechanisms, which can lead to the formation of a stagnant layer of liquid on the heating plate surface. This results in low heat transfer efficiency and a tendency for localized overheating. Such localized overheating can then promote the formation of scale or salt deposits on the heating surface, affecting overall evaporation efficiency, increasing energy consumption, and making subsequent cleaning extremely difficult. Furthermore, traditional devices typically employ a fixed crystallization collection design, making it inconvenient to remove salt crystals. This may require tilting the entire device, disassembling parts, or relying on manual tools to scrape them from the tank. Such operations are not only labor-intensive but also prone to material loss and potential environmental pollution. Moreover, the cleaning process is often more time-consuming and labor-intensive.

[0004] Therefore, those skilled in the art have provided a crystallization separation device for high-salt wastewater to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-salt wastewater crystallization separation device. Through a servo motor and gear transmission, the rotating stirring blades continuously agitate the liquid within the evaporation chamber, preventing the formation of a static layer on the heating plate surface. This enhances convective heat transfer, resulting in a more uniform liquid temperature and increased evaporation rate. Furthermore, the agitation keeps the forming micro-salt crystals suspended, preventing premature settling and promoting crystal growth, leading to a more uniform crystalline product. Additionally, the movable receiving rack allows for easy removal from the evaporation chamber for unloading and cleaning after the chamber is full of salt crystals, making operation convenient.

[0006] To achieve the above objectives, this utility model provides a high-salt wastewater crystallization separation device, including a sedimentation tank and an evaporation chamber. Multiple heating plates are fixedly connected to the inner wall of the evaporation chamber. A protective shell is fixedly connected to the upper surface of the evaporation chamber. A servo motor is fixedly connected to the inner top surface of one side of the protective shell. A drive gear is fixedly connected to the output end of the servo motor. A driven gear meshes with the other side of the drive gear. A stirring rod is fixedly connected to the middle of the lower end of the driven gear. The lower end of the stirring rod penetrates the evaporation chamber to the lower end of the evaporation chamber and is fixedly connected to multiple stirring blades. A sedimentation funnel is connected through the lower end of the evaporation chamber. An electromagnetic control valve is fitted onto the outer wall of the lower end of the sedimentation funnel. An installation groove is opened at the lower part of the front end of the evaporation chamber. A crystal receiving rack is installed inside the installation groove. The outer walls of the crystal receiving rack are tightly fitted to the inner wall of the installation groove. Multiple leakage holes are opened on the inner bottom surface of the rear end of the crystal receiving rack. The upper surface of the rear end of the crystal receiving rack is at the same level as the lower surface of the sedimentation funnel.

[0007] The above technical solution, by evenly arranging multiple heating plates on the inner wall of the evaporation chamber, increases the heating area, allowing for more uniform heat transfer to the wastewater and improving evaporation efficiency. The servo motor and gear drive ensure continuous agitation of the liquid within the evaporation chamber by the rotating stirring blades, preventing the formation of a stagnant layer on the heating plate surface. This enhances convective heat transfer, resulting in a more uniform liquid temperature and increased evaporation rate. Furthermore, stirring keeps the forming micro-salt crystals in suspension, preventing premature settling and promoting crystal growth, leading to more uniform crystalline products. The sedimentation funnel, located at the bottom of the evaporation chamber, is shaped to guide the flow of liquid and solids. At the bottom of the funnel, the receiving rack is located directly below the sedimentation funnel. It can collect the salt crystals settling from the bottom of the funnel. The design of the funnel hole allows the mother liquor to pass through, while the salt crystals are trapped in the receiving rack. This achieves preliminary solid-liquid separation, so that the collected salt crystals contain less mother liquor, reducing the cost of subsequent drying or processing. The movable receiving rack makes it easy to remove the salt crystals from the evaporation chamber for unloading and cleaning after it is full. The operation is convenient. In addition, the electromagnetic control valve can control the discharge of mother liquor or a small amount of underflow. This helps to close the valve when collecting crystals to prevent crystal loss, or open the valve when it is necessary to discharge mother liquor or perform cleaning.

[0008] Furthermore, the sedimentation tank is located on one side of the evaporation chamber. An inlet pipe is connected to the outer wall of the upper end of one side of the sedimentation tank. A first water pump is installed on one side of the upper surface of the sedimentation tank. The suction port of the first water pump is connected to the upper end of the interior of the sedimentation tank through a pipe. A filter is fixedly connected to the other side of the upper surface of the sedimentation tank. The outlet of the first water pump is connected to the inlet of the filter through a pipe. A second water pump is installed at the upper end of the filter. The suction port of the second water pump is connected to the outlet of the filter through a pipe. The outlet of the second water pump is connected to the interior of the evaporation chamber through a pipe.

[0009] Through the above technical solution, the wastewater entering the evaporation chamber is purified by sedimentation and filtration, reducing the interference of impurities on the evaporation process, improving evaporation efficiency, and protecting the evaporation chamber and related pipelines from blockage. Furthermore, suspended solids or impurities in the wastewater may coat the surface of the salt crystals, affecting the purity and morphology of the crystals and leading to a decrease in the quality of the obtained salt crystals. Pretreatment removes these interfering substances, which helps to obtain purer salt crystals with more regular particles.

[0010] Furthermore, sliding grooves are provided on both sides of the inner wall of the mounting groove, and sliding plates are fixedly connected to both sides of the outer wall of the crystal receiving rack. The outer walls of the sliding plates slide against the inner wall of the sliding groove, and a handle is fixedly connected to the outer wall of the front end of the crystal receiving rack.

[0011] Through the above technical solution, the sliding fit allows the crystal receiving rack to be easily pulled out or pushed in from the mounting slot. After the crystallization process is completed, the operator can easily grasp the handle to pull the receiving rack full of salt crystals out of the evaporation chamber and remove the receiving rack containing a large amount of salt crystals from the evaporation chamber. This makes subsequent unloading, weighing, transfer, or further processing simple and quick. The cooperation between the sliding slot and the sliding plate provides guidance for the receiving rack, ensuring that it moves smoothly in the mounting slot without tilting or getting stuck. When a receiving rack is full, it can be quickly pulled out and an empty receiving rack can be pushed in. This allows the crystallization and collection process to be carried out continuously or semi-continuously, improving the overall processing efficiency.

[0012] Furthermore, the lower ends of both the driving gear and the driven gear are rotatably connected to the upper surface of the evaporation chamber, and both the driving gear and the driven gear are located inside the protective shell;

[0013] The above technical solution provides a stable and low-friction fulcrum for the gear by rotating the lower end of the gear to the upper surface of the evaporation chamber. This structural design is more stable than cantilever support or positioning by shoulder alone, which helps to reduce vibration and sway during transmission. The protective shell is used to protect the internal transmission components from interference from external factors.

[0014] Furthermore, a mother liquor tank is provided on the inner bottom surface of the mounting groove, and an inclined plate is provided at the lower end of the mother liquor tank. The outer wall of the inclined plate is in close contact with the inner wall of the lower end of the mother liquor tank. A third water pump is provided at the upper end of the other side of the evaporation chamber. The suction port of the third water pump is connected to a connecting pipe. The lower end of the connecting pipe is connected to the interior of the mother liquor tank. The outlet of the third water pump is connected to the interior of the upper end of the evaporation chamber through a pipe.

[0015] Through the above technical solution, in the process of evaporation and crystallization of high-salt wastewater, not all water can be completely removed in the first evaporation. A portion of the concentrated mother liquor is collected in a mother liquor tank and then transported back to the evaporation chamber by a third water pump, realizing the recycling of the mother liquor. Through circulation, the salt in the mother liquor can continue to be concentrated in the evaporation chamber and eventually crystallize out, thereby improving the total salt recovery rate. The inclined plate helps to more effectively collect the mother liquor flowing to the bottom of the mother liquor tank to the vicinity of the pump's suction port.

[0016] Furthermore, a fixing rod is fixedly connected to one side of the third water pump, and one side of the fixing rod is fixedly connected to the outer wall of the other side of the evaporation chamber;

[0017] The above technical solution uses a fixing rod to fix the third water pump.

[0018] Furthermore, a PLC control panel is fixedly connected to the outer wall of the front end of the evaporation chamber, and a temperature sensor is fixedly connected to the inner top surface of the evaporation chamber.

[0019] The above technical solution uses a PLC control panel to monitor and adjust the entire wastewater treatment process, and a temperature sensor to monitor the temperature inside the evaporation chamber. This makes the monitoring of the core evaporation process more accurate, helps to optimize operating parameters, and improves treatment efficiency.

[0020] This utility model has the following beneficial effects:

[0021] This invention proposes a high-salt wastewater crystallization separation device. Through a servo motor and gear transmission, the rotation of the stirring blades continuously agitates the liquid in the evaporation chamber, preventing the formation of a stagnant layer on the heating plate surface. This helps to enhance convective heat transfer, making the liquid temperature more uniform and increasing the evaporation rate. Furthermore, the stirring keeps the forming micro-salt crystals in suspension, preventing premature settling and promoting crystal growth, resulting in a more uniform crystalline product. In addition, the movable receiving rack allows for easy removal from the evaporation chamber for unloading and cleaning after the chamber is full of salt crystals, making the operation convenient.

Multiple heating plates 203 are fixedly connected to the inner wall of the evaporation chamber 2. A protective shell 202 is fixedly connected to the upper surface of the evaporation chamber 2. A servo motor 4 is fixedly connected to the inner top surface of one side of the protective shell 202. A drive gear 401 is fixedly connected to the output end of the servo motor 4. A driven gear 402 meshes with the other side of the drive gear 401. A stirring rod 403 is fixedly connected to the middle of the lower end of the driven gear 402. The lower end of the stirring rod 403 penetrates the evaporation chamber 2 to the lower end inside the evaporation chamber 2 and is fixed. Multiple stirring blades 404 are connected to the evaporation chamber 2. A sedimentation funnel 204 is connected through the lower end of the evaporation chamber 2. An electromagnetic control valve 205 is fitted on the outer wall of the lower end of the sedimentation funnel 204.

Multiple drainage holes 501 are opened on the inner bottom surface of the rear end of the crystal receiving rack 5. The upper surface of the rear end of the crystal receiving rack 5 is at the same level as the lower surface of the sedimentation funnel 204. By evenly arranging multiple heating plates 203 on the inner wall of the evaporation chamber 2, the heating surface can be increased. The servo motor 4 and gear drive continuously agitate the liquid in the evaporation chamber 2 by rotating the stirring blades 404, preventing the formation of a stagnant layer on the surface of the heating plate 203. This enhances convective heat transfer, resulting in a more uniform liquid temperature and increased evaporation rate. Furthermore, the agitation keeps the forming micro-salt crystals in suspension, preventing premature settling and promoting crystal growth for a more uniform crystalline product. The sedimentation funnel 204 is located at the bottom of the evaporation chamber 2, and its shape helps guide the liquid and solid flow to the bottom of the funnel. The receiving rack is located at the sedimentation funnel 204. Directly below 04, salt crystals settling from the bottom of the funnel can be collected. The design of the funnel hole 501 allows the mother liquor to pass through, while the salt crystals are trapped in the receiving rack. This achieves preliminary solid-liquid separation, resulting in collected salt crystals containing less mother liquor, reducing the cost of subsequent drying or processing. The movable receiving rack allows for easy removal from the evaporation chamber 2 for unloading and cleaning after it is full of salt crystals. The operation is convenient. In addition, the electromagnetic control valve 205 can control the discharge of mother liquor or a small amount of underflow. This helps to close the valve when collecting crystals to prevent crystal loss, or to open the valve when it is necessary to discharge mother liquor or perform cleaning.

Furthermore, suspended solids or impurities in the wastewater may coat the surface of salt crystals, affecting the purity and morphology of crystallization, leading to a decrease in the quality of the obtained salt crystals. Pretreatment removes these interferences. The material helps to obtain purer, more uniformly sized salt crystals. Sliding grooves 207 are provided on both sides of the inner wall of the mounting groove 206. Sliding plates 502 are fixedly connected to both sides of the outer wall of the crystal receiving rack 5.

After the crystallization process is complete, the operator can easily grasp the handle 503. The receiving rack filled with salt crystals is pulled out of the evaporation chamber 2, and the receiving rack containing a large amount of salt crystals is moved out of the evaporation chamber 2, making subsequent unloading, weighing, transfer or further processing simple and quick. The cooperation of the sliding groove 207 and the sliding plate 502 provides guidance for the receiving rack, ensuring that it moves smoothly in the mounting groove 206 without tilting or getting stuck.

Both the driving gear 401 and the driven gear 402 are located inside the protective shell 202. By rotatably connecting the lower ends of the gears to the upper surface of the evaporation chamber 2, a stable and low-friction rotational fulcrum is provided for the gears. This structural design is more stable than cantilever support or positioning solely by a shaft shoulder, helping to reduce vibration and sway during transmission.

To mitigate interference, a mother liquor tank 208 is provided on the inner bottom surface of the mounting tank 206.

During the evaporation and crystallization process of high-salt wastewater... Not all water is completely removed during the first evaporation. A portion of the concentrated mother liquor is collected in the mother liquor tank 208 and then pumped back to the evaporation chamber 2 by the third water pump 3, thus achieving mother liquor recycling. Through recycling, the salt in the mother liquor can continue to concentrate and eventually crystallize in the evaporation chamber 2, thereby improving the total salt recovery rate. The inclined plate 209 helps to more effectively collect the mother liquor flowing to the bottom of the mother liquor tank 208 near the pump's suction port. A fixing rod 302 is fixedly connected to one side of the third water pump 3, and one side of the fixing rod 302 is fixedly connected to the outer wall of the other side of the evaporation chamber 2.

[0033] Working principle: High-salinity wastewater first enters sedimentation tank 1 through inlet pipe 101. In sedimentation tank 1, the wastewater undergoes preliminary sedimentation, causing large suspended particles to settle to the bottom. Subsequently, the first water pump 102 extracts the supernatant and sends it to filter 103 to remove fine suspended solids and impurities from the water. Then, the second water pump 104 pumps the filtered water into the upper part of evaporation chamber 2. Inside evaporation chamber 2, multiple heating plates 203 evenly distributed on the inner wall heat the wastewater, causing it to boil and evaporate. At the same time, the servo motor 4 inside the protective shell 202 drives the drive gear 401 and driven gear 402 to mesh and rotate. This, in turn, causes the stirring rod 403 and stirring blade 404 to rotate within the evaporation chamber 2. The stirring blade 404 agitates the liquid, which helps promote uniform heat transfer, prevents coking of the heating plate 203, and keeps the salt crystals in suspension, which is beneficial for crystal growth. The steam generated by evaporation escapes from the top of the evaporation chamber 2. As the water continues to evaporate, the solution concentration gradually increases, and the salt begins to crystallize and precipitate. The PLC control panel 201 intelligently controls the power of the heating plate 203 and the stirring speed based on parameters monitored by temperature sensors, etc., to optimize the crystallization process. The salt crystals produced by crystallization begin to settle under the action of gravity and precipitate. The funnel 204 guides the settling salt crystals and liquid to its bottom. The salt crystals fall into the crystal receiving rack 5 in the lower mounting groove 206 at the front end of the evaporation chamber 2. The leakage hole 501 at the rear end of the receiving rack allows the mother liquor to pass through, thus trapping the salt crystals in the receiving rack. The small amount of mother liquor or underflow that settles at the bottom of the funnel can be discharged under control by the electromagnetic control valve 205. The mother liquor flowing through the leakage hole 501 of the receiving rack and the mother liquor discharged from the electromagnetic control valve 205 will collect in the mother liquor tank 208. The inclined plate 209 set in the mother liquor tank 208 helps to collect the mother liquor more effectively. The third water pump 3 pumps water through the connecting pipe 301. The collected mother liquor is drawn out from the mother liquor tank 208 and then transported back to the upper part of the evaporation chamber 2, so that the mother liquor re-enters the evaporation and crystallization cycle. This not only improves the utilization efficiency of water resources, but also increases the total salt recovery rate. When the receiving rack is full of salt crystals, the operator can hold the handle 503 at the front end and use the sliding plates 502 on both sides of the receiving rack to easily slide it in the sliding grooves 207 on both sides of the installation tank 206 to draw the receiving rack full of salt crystals out of the evaporation chamber 2 for subsequent salt crystal unloading, weighing, transfer or further processing. Then, an empty receiving rack can be pushed in to continue the crystallization collection work.
