Description

Technical Field

[0001] This utility model relates to the field of wastewater evaporation and extraction technology, and in particular to a rapid evaporation and extraction device for heavy metal wastewater. Background Technology

[0002] Heavy metal wastewater refers to wastewater containing heavy metals (such as cadmium, nickel, mercury, and zinc) discharged during industrial production processes in mining, metallurgy, machinery manufacturing, chemical, and electronics industries. This type of wastewater is among the most polluting and harmful industrial wastewaters to humans. Because heavy metals are difficult to degrade in the environment and easily accumulate through the food chain, they pose a serious threat to human health and the ecological environment. Therefore, the monitoring and effective treatment of heavy metal wastewater are of paramount importance.

[0003] The detection process for heavy metal wastewater typically includes sample collection and preparation, pretreatment, selection of detection methods, detection operation, and result recording and reporting. Evaporation extraction plays a crucial role in the detection and treatment of heavy metal wastewater. Evaporation reduces the volume of wastewater while concentrating heavy metals, facilitating the detection of their content and composition. Extraction technology utilizes the selectivity of specific solvents to separate heavy metals from wastewater, enabling heavy metal monitoring and analysis. A typical heavy metal wastewater evaporation extraction device usually consists of a heating system, an evaporation chamber, an extraction chamber, and a control system. The heating system provides the energy required for evaporation, the evaporation chamber enables rapid evaporation of the wastewater, and the extraction chamber uses an extractant to separate heavy metals from the evaporation residue.

[0004] However, existing heavy metal wastewater evaporation and extraction devices use different evaporation temperatures when treating wastewater with different heavy metal components. In the existing technology, the evaporation container is generally placed in a heating container and heated by water temperature. When different temperatures are required, or when the temperature needs to be increased, it is necessary to reheat, which takes a long time. Utility Model Content

[0023] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] See Figures 1 to 3This utility model provides a rapid evaporation and extraction device for heavy metal wastewater, comprising a base 1, a frame 2, and a controller 20. The frame 2 is located on the top surface of the base 1. A moving mechanism is provided at the top of the frame 2, and a U-shaped frame 9 is provided at the bottom of the moving mechanism. A rotating shaft 10 is rotatably mounted at the bottom of the U-shaped frame 9. The rotating shaft 10 passes through the U-shaped frame 9 and drives a first motor 3. The first motor 3 is located on the side of the U-shaped frame 9 and is a stepper motor that can precisely control the rotation angle. A first electric push rod 12 is provided on the rotating shaft 10. The telescopic end of the first electric push rod 12 is connected to a housing 13. A rotating mechanism is provided in the middle of the housing 13, and one end of the rotating mechanism is connected to a... A flask 14 is connected to a conduit 21 at one end. The conduit 21 is connected to the flask 14 via a rotating mechanism. Multiple heating tanks 15 are located below the flask 14 and are situated on the top surface of the base 1. The end of the conduit 21 away from the rotating mechanism is connected to a condenser 25. A spiral cooling tube 31 is installed inside the condenser 25. The upper and lower ends of the spiral cooling tube 31 are connected to a cooler 29 via an inlet pipe 27 and an outlet pipe 28, respectively. The cooler 29 is mounted on the frame 2 and is used to continuously introduce cold water into the spiral cooling tube 31 through the inlet pipe 27 and return it through the outlet pipe 28. The cooler 29 is a conventional technology, and its specific structure will not be described in detail. The condenser 25 is provided with a feed pipe 22 on its side. The feed pipe 22 passes through the condenser and is located inside the conduit 21 and extends into the flask 14. The feed pipe 22 is provided with a feed valve 23. The bottom of the condenser 25 is connected to a collection bottle 26, which is located on the top surface of the base 1. The controller 20 is located on the top surface of the frame 2 and is electrically connected to the moving mechanism, the rotating mechanism, the cooler 29, the first motor 3, the first electric push rod 12 and the feed valve 23. The controller 20 adopts a low-power microprocessor of model STM32-L0.

[0025] When the heavy metal wastewater rapid evaporation and extraction device is working, firstly, the feed valve 23 is opened, and the heavy metal wastewater to be evaporated and extracted enters the flask 14 through the feed pipe 22. Then, the moving mechanism is activated, so that the U-shaped frame 9 is positioned at a preset position above the heating tank 15. Then, the first motor 3 is activated, and the rotation of the first motor 3 drives the rotating shaft 10 to rotate, thereby driving the first electric push rod 12 to rotate. When the first electric push rod 12 drives the housing 13 to rotate to a preset angle, the bottom of the flask 14 connected to the rotating mechanism is at the water surface in the middle heating tank 15, so that the flask 14 enters the water to a suitable depth. The first electric actuator 12 extends to adjust the depth of the flask 14 immersed in the water. When the flask 14 reaches the appropriate depth, the first electric actuator 12 is stopped, and then the rotating mechanism is started. The rotating mechanism drives the flask 14 to rotate, so that the sewage in the flask 14 is heated by the hot water in the heating tank 15. After the sewage evaporates, it passes through the rotating mechanism and the conduit 21 into the condenser. When the evaporated gas encounters the spiral cooling tube 31 in the condenser, it condenses into liquid, which continuously gathers into water droplets and falls into the collection bottle 26 at the bottom. Heavy metal wastewater contains various substances with different evaporation temperatures. After evaporation extraction at one temperature is completed, the collection bottle 26 is replaced first. The flask 14 needs to be moved to another heating tank 15 containing a preset temperature. The moving mechanism is activated, positioning the U-shaped frame 9 above the heating tank 15. Then, the first motor 3 is activated, rotating the shaft 10, which in turn rotates the first electric push rod 12. Once the first electric push rod 12 rotates the housing 13 to a preset angle, the bottom of the flask 14 connected to the rotating mechanism is positioned in the middle of the heating tank 15. On the surface, the flask 14 is submerged to a suitable depth in the water. By activating the first electric push rod 12, the extension end of the first electric push rod 12 can be extended to adjust the immersion depth of the flask 14 in the water. When the flask 14 is submerged to a suitable depth, the first electric push rod 12 is stopped, and then the rotating mechanism is activated. The rotating mechanism drives the flask 14 to rotate. Through the moving mechanism, the first electric push rod 12, and the first motor 3, the flask 14 can be quickly moved to different heating tanks 15. The heating tank 15 contains water at a preset temperature, thereby reducing the waiting time for the water in the heating tank 15 to rise in temperature and improving the evaporation and extraction efficiency.

[0026] Preferably, the moving mechanism includes a second motor 7, a turntable 4, a support plate 5, a lead screw 6, a third motor 11, and a moving block 8. The turntable 4 is rotatably mounted on the top ground of the frame 2. The second motor 7 is mounted on the top surface of the frame 2, and its output shaft passes through the frame 2 and drives the turntable 4. The second motor 7 is a stepper motor that can precisely control the rotation angle. The support plate 5 is positioned opposite each other on the bottom surface of the turntable 4. The lead screw 6 is rotatably mounted between the two support plates 5, with one end rotatably connected to the support plate 5 and the other end passing through the support plate 5 and driving the third motor 11. The third motor 11 is mounted on the side of the support plate 5 and is a stepper motor that can precisely control the rotation angle. The moving block 8 is mounted on the lead screw 6.

[0027] The moving mechanism is used to change the position of the U-shaped frame 9. When the third motor 11 is started, the third motor 11 rotates and drives the lead screw 6 to rotate. The rotation of the lead screw 6 drives the moving block 8 to move along the axis of the lead screw 6. First, the moving block 8 moves to the middle position of the lead screw 6. Then, the first motor 3 is started. The rotation of the first motor 3 drives the rotating shaft 10 to rotate, thereby driving the first electric push rod 12 to rotate. When the first electric push rod 12 drives the housing 13 to rotate to a preset angle, the bottom of the flask 14 connected to the rotating mechanism is on the water surface in the intermediate heating tank 15, so that the flask 14... Once the flask 14 reaches the appropriate depth in the water, the first electric actuator 12 is activated. The extension of the telescopic end of the first electric actuator 12 can adjust the immersion depth of the flask 14. When the flask 14 reaches the appropriate depth, the first electric actuator 12 is stopped. Similarly, the second motor 7 is activated. The rotation of the second motor 7 drives the turntable 4 and the support plate 5 to rotate, thereby allowing the lead screw 6 to rotate at a certain angle. This, in conjunction with the adjustment of the third motor 11 and the first electric actuator 12, allows the flask 14 to enter different heating tanks 15 and reach the appropriate immersion depth.

[0028] Preferably, the rotating mechanism includes a drive tube 16, a gear ring 17, a gear 18, a fourth motor 19, a rotating tube 35, and a connecting sleeve 36. The drive tube 16 is rotatably disposed in the middle of the housing 13 and extends out of the side of the housing 13 at both ends. The gear ring 17 is sleeved on the rotating tube 35 and meshes with the gear 18. The fourth motor 19 is embedded in the side of the housing 13, and its output shaft drives the gear 18. One end of the drive tube 16 is fixedly sleeved on the end of the flask 14, and the other end is fixedly sleeved on the rotating tube 35. The connecting sleeve 36 is rotatably connected to the rotating tube 35, and the guide tube 21 is fixedly sleeved on the connecting sleeve 36.

[0029] The rotating mechanism drives the flask 14 to rotate, thereby increasing the contact area between the flask 14 and the water in the heating tank 15 and improving the wastewater evaporation efficiency. When the fourth motor 19 is started, the rotation of the fourth motor 19 drives the gear 18 to rotate, the rotation of the gear 18 drives the gear ring 17 to rotate, and the rotation of the gear ring 17 drives the rotating tube 35 to rotate, thereby driving the flask 14 to rotate.

[0030] Preferably, it also includes a vacuum pump 33 and a vacuum tube 32. The vacuum pump 33 is located on the top surface of the frame 2. One end of the vacuum tube 32 is connected to the vacuum pump 33 and the other end is connected to the condenser tank 25. The vacuum pump 33 is electrically connected to the controller 20.

[0031] Vacuum pump 33 is used to maintain a certain vacuum in the condenser tube. When vacuum pump 33 is started, vacuum pump 33 extracts air from the condenser tube through vacuum tube 32 to maintain a certain vacuum, thereby reducing the gas pressure of wastewater in flask 14, lowering the boiling point of wastewater, and facilitating the acceleration of wastewater evaporation and extraction.

[0032] Preferably, the conduit 21 is made of flexible polyethylene.

[0033] When the moving mechanism moves the housing 13, the conduit 21 will deform as the position of the housing 13 changes. The conduit 21 is made of flexible polyethylene and can deform with the housing 13 to complete the moving operation, thus avoiding the risk of it falling off due to lengthening or shortening.

[0034] Preferably, it also includes a feed cup 24, which is disposed on the top surface of the base 1, and the feed tube 22 is located inside the feed cup 24.

[0035] When the feeding operation is performed, the wastewater to be evaporated and extracted is poured into the feed cup 24, and then the vacuum pump 33 is started. The vacuum pump 33 maintains the vacuum degree of the condenser tube through the vacuum tube 32. Then the feed valve 23 is opened, and the feed tube 22 generates suction to draw the wastewater in the feed cup 24 into the feed tube 22 and flow into the flask 14. After the feeding operation is completed, the feed valve 23 is closed.

[0036] Preferably, it also includes a heater 37 and a temperature sensor 34, which are disposed inside the heating barrel 15 and electrically connected to the controller 20.

[0037] The heater 37 and temperature sensor 34 are located inside the heating tank 15. The controller 20 controls the heater 37 to heat the water in the heating tank 15 according to the condition of the heavy metal wastewater. When the temperature sensor 34 detects that the water temperature has reached the preset temperature, the heater 37 is stopped. At the same time, when the temperature sensor 34 detects that the water temperature is lower than the preset temperature, the controller 20 can start the heater 37 to heat the water in the heating tank 15, thereby maintaining a stable water temperature, which is beneficial to the evaporation and extraction of heavy metal wastewater.

[0038] Preferably, it also includes a support leg 30, which is disposed at the bottom of the base 1.

[0039] The support leg 30 is used to support the weight of the entire device and keep the evaporation extraction device stable during operation. The support leg 30 is connected to the base 1 by bolts or welding.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
