Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of wastewater treatment equipment, concretely is a kind of separating device for wastewater heavy metal detection and analysis. BACKGROUND

[0002] In the field of wastewater treatment and environmental monitoring, it is crucial to accurately detect and analyze the heavy metal content in wastewater. If heavy metals are discharged into the environment without effective treatment, they can cause serious harm to the ecosystem and human health. However, heavy metals in wastewater often exist in multiple forms, possibly forming complex mixtures or colloids with other substances, which makes it necessary to perform efficient separation operations on wastewater before detection and analysis.

[0003] Traditional wastewater heavy metal separation methods have many limitations. For example, using simple precipitation method, the separation efficiency is low and time-consuming, and it is difficult to completely separate the fine particulate heavy metals, resulting in inaccurate subsequent detection results. While centrifugal separation method has high efficiency, it has high equipment cost, high energy consumption and strict operation technology requirements, which is difficult to be widely applied. In addition, some existing separation devices cannot well realize the classification collection of different forms of pollutants during the separation process, increasing the difficulty of subsequent treatment. In actual operation, traditional devices often need frequent manual intervention, such as manual cleaning of separated pollutants, which not only reduces work efficiency, but also may cause operators to contact harmful substances, posing a threat to health. With the increasing environmental protection requirements and the continuous development of detection technology, there is an urgent need for a wastewater separation device that is simple to operate, energy-efficient and can accurately separate heavy metals.

[0012] Advantages:

[0013] One, efficient separation process: the separation device realizes multi-stage separation of wastewater through the cooperation of the stirring drum, the draining tank and the separation tank. The stirring blades in the stirring drum can quickly stir the wastewater under the drive of the third motor, which helps to disperse the impurities in the wastewater and facilitates subsequent separation operations. The wastewater enters the stirring drum through the water inlet pump and the water inlet pipeline, and after stirring, it enters the draining tank through the intermediate pipeline. In the draining tank, the conveying belt and the conveying roller in the conveying assembly cooperate to preliminarily drain the wastewater, allowing most of the water to drain through the draining holes, reducing the burden of subsequent separation. Then, the preliminarily treated wastewater is conveyed to the separation tank through the sewage outlet for further separation. The whole process is coherent and efficient.

[0014] Two, precise heavy metal separation: the magnetic roller in the separation tank is the key component for separating heavy metals. The magnetic roller driven by the first motor can efficiently adsorb magnetic heavy metal particles in the wastewater through the magnetic force generated by the electromagnetic magnetic ring. Moreover, the electromagnetic magnetic ring is electrically connected with the controller, which can flexibly adjust the magnetic force size according to the content and properties of heavy metals in the wastewater, ensuring precise adsorption of different types of heavy metals and greatly improving the accuracy and pertinence of separation.

[0015] Three, convenient cleaning and maintenance: the storage box connected to the bottom of the separation tank can collect heavy metal particles adsorbed on the magnetic roller. When cleaning is needed, the storage box can be easily removed. Meanwhile, the moving plate can drive the material pushing ring to scrape the heavy metal particles off the magnetic roller and make them fall into the storage box through the cooperation of the lead screw and the second motor. The sliding groove and the retractable sealing strip arranged on the separation tank not only ensure smooth sliding of the moving plate, but also enhance the sealing performance of the separation tank to prevent wastewater leakage. In addition, the sealing shell can be detachably connected to the outer wall of the separation tank, which facilitates maintenance and repair of the internal components.

[0016] Four, reasonable structure design: the detachable connection between the draining tank and the separation tank facilitates assembly and disassembly according to different wastewater treatment needs, improving the flexibility and versatility of the device. The layout of the stirring drum, the draining tank and the separation tank is compact, occupying a small area, which is suitable for wastewater treatment sites of different scales. Moreover, the driving devices of all components are driven by motors, which are powerful and stable, ensuring efficient operation of the whole separation process and reducing energy consumption.

[0017] Five, ensuring the safety of operators: the whole separation process is highly automated, reducing the opportunity for manual direct contact with wastewater and heavy metals, effectively protecting the health of operators. The sealing design of the device avoids leakage of wastewater and heavy metal particles, further reducing the risk of environmental pollution. BRIEF DESCRIPTION OF DRAWINGS

[0042] Workflow

[0043] I. Stirring stage: Start the third motor 21 to drive the stirring blade 20 in the stirring drum 1 to start rotating. Pour the wastewater to be treated into the stirring drum 1, and the stirring blade 20 stirs the wastewater thoroughly to ensure uniformity and effectiveness of the subsequent separation operation.

[0044] II. Preliminary draining stage: After stirring is completed, start the water inlet pump 5 to transport the stirred wastewater to the draining tank 2 through the water inlet pipeline 6. After the wastewater enters the draining tank 2, start the power assembly of the conveying assembly to drive the conveying roller 23 to rotate, and in turn drive the conveying belt 22 to operate. The wastewater flows on the conveying belt 22, and part of the water is discharged through the draining holes 24 on the conveying belt 22, preliminarily realizing solid-liquid separation.

[0045] III. Further separation stage: After the initial draining, the wastewater enters the separation tank 3 through the drain outlet 9 of the draining tank 2.

Since the magnetic roller 10 includes an electromagnetic magnetic ring and an intermediate roller, and the electromagnetic magnetic ring is electrically connected to the controller, the size of the electromagnetic force of the magnetic roller 10 can be adjusted by the controller according to the type and concentration of heavy metals in the wastewater, thereby adsorbing and separating the heavy metals in the wastewater. As the magnetic roller 10 rotates, the heavy metals in the wastewater are adsorbed on the surface of the magnetic roller 10.

[0046] III. Collection and cleaning stage: When the magnetic roller 10 adsorbs a certain amount of heavy metals, the second motor 16 is started to drive the lead screw 15 to rotate. Since the moving plate 12 is threadedly connected to the lead screw 15, the moving plate 12 slides along the sliding groove 17 under the drive of the lead screw 15. The pushing ring 13 on the moving plate 12 will scrape off the heavy metals adsorbed on the magnetic roller 10. The scraped heavy metals fall into the storage box 11 at the bottom of the separation tank 3 under the action of gravity.

[0047] IV. Wastewater discharge stage: After the heavy metal separation is completed, the valve 8 on the water outlet pipe 7 is opened, and the treated wastewater is discharged from the separation tank 3 for subsequent heavy metal detection analysis or other treatment processes.

[0048] The above wastewater heavy metal detection and analysis separation device realizes efficient separation of heavy metals in wastewater through multi-stage separation operation. Each step is closely coordinated, which not only improves the separation efficiency but also ensures the separation effect.
