Description

Technical Field

[0001] This utility model belongs to the field of wastewater sampling and testing, and specifically relates to a centrifuge device for wastewater sampling and testing. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial sources that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. It is mainly water used in daily life, which contains more organic matter and is relatively easy to treat. From the perspective of wastewater source, wastewater can be defined as liquid or water carrying waste that is discharged from residential, government, commercial or industrial areas and mixed with groundwater, surface water and snowstorms. There are many categories of wastewater, and correspondingly, there are many technologies and processes to reduce the impact of wastewater on the environment. According to the source of wastewater, wastewater can be divided into these four categories.

[0003] Chinese Patent No. CN211521782U discloses a centrifuge device for wastewater sampling and testing, comprising an outer casing, an internal centrifuge mechanism, a first drive motor, a first bevel gear at the output end of the first drive motor, a first rotating shaft at the top of the first bevel gear, a bearing seat at the top of the first rotating shaft, a centrifuge housing fixedly mounted at the top of the bearing seat, a second bevel gear on one side of the first bevel gear, a second rotating shaft on one side of the second bevel gear, a drive wheel at one end of the second rotating shaft, a driven wheel at the top of the drive wheel, a third rotating shaft on one side of the driven wheel, a third bevel gear at one end of the third rotating shaft, a fourth bevel gear on one side of the third bevel gear, and a third bearing at the top of the fourth bevel gear. This invention improves stirring efficiency, facilitates wastewater testing, and yields more accurate results.

[0004] As can be seen from the above structure, the centrifuged wastewater is filtered through the first impurity filter plate, the second impurity filter plate, and the activated carbon adsorption plate in sequence to remove impurities. The impurities on the first impurity filter plate, the second impurity filter plate, and the activated carbon adsorption plate can be detected. However, none of the surfaces of the first impurity filter plate, the second impurity filter plate, and the activated carbon adsorption plate are equipped with scraping structures. As a result, when larger impurities are filtered through the surface of the first impurity filter plate, it can cause the first impurity filter plate to be damaged, thus preventing smaller impurities from being effectively filtered. This ultimately affects the accuracy of impurity detection. Utility Model Content

This rotation of the cleaning rod, combined with the action of the cleaning brush, brushes the filter disc, thus preventing impurities from adsorbing inside the filter disc and affecting filtration. The rotating filter disc prevents it from rotating during the brushing action, allowing for layered filtration of impurities of different sizes through the action of multiple filter discs. This enables precise detection of impurities in the wastewater.

[0016] Secondly, this utility model, through its adjustable component, allows for the collection of impurities inside the filter disc during use. By controlling the adjustment motor to rotate, the adjusting screw rotates, causing the threaded component connected to it to move. This movement of the threaded component then moves the mounting rod, which is fixedly connected to the first and second barrel covers. Consequently, the movement of the mounting rod moves the second barrel cover, allowing the filter disc to be moved out of the filter barrel. This facilitates material removal during use, and opening the first and second barrel covers facilitates cleaning. Attached Figure Description

A mixing rod 24 is fixedly connected through the output shaft of the mixing motor 23 through the first tank cover 22. Mixing blades 25 are fixedly connected to the outer side of the mixing rod 24. By placing sewage inside the centrifuge tank 21, and then controlling the mixing motor 23 to drive the mixing rod 24 to rotate, the rotation of the mixing rod 24 drives the mixing blades 25 to rotate, thereby centrifuging the sewage inside during use.

[0025] refer to Figure 1 The outer surface of the centrifuge tank 21 is provided with observation slots 6, and observation plates 7 are fixedly connected to the inner side of the observation slots 6. The periphery of the observation plates 7 is sealed to the inner side of the observation slots 6. The observation plates 7 can be used to monitor the internal sewage centrifugation status in real time.

[0026] refer to Figure 1 , Figure 2 and Figure 4 The upper end of the centrifuge bucket 21 is inserted into the lower end of the first bucket cover 22.

By controlling the adjustment motor 38 to rotate, the adjusting screw 35 is driven to rotate. The rotation of the adjusting screw 35 causes the threaded part 36 connected to it to move. Thus, the movement of the threaded part 36 can drive the mounting rod 37 to move. The mounting rod 37 is fixedly connected to the first barrel cover 22 and the second barrel cover 42. Thus, the movement of the mounting rod 37 can drive the second barrel cover 42 to move the filter disc 45 out of the filter barrel 41, thereby making it convenient to remove materials during use.

[0028] refer to Figure 2 The upper end of the base plate 1 is fixedly connected to the outer shell 10, and the inside of the outer shell 10 is fixedly connected to the electric push rod 11. The other end of the electric push rod 11 is fixedly connected to the universal wheel 12, and the universal wheel 12 is slidably inserted into the outer shell 10. By controlling the electric push rod 11, the universal wheel 12 is extended out of the outer shell 10 under the action of the electric push rod 11. Thus, when the universal wheel 12 is extended out of the outer shell 10, it can be moved by the universal wheel 12. When fixing the device, the universal wheel 12 can be moved into the inside of the outer shell 10 so that the base plate 1 contacts the ground. This increases the contact area between the device and the ground when the base plate 1 contacts the ground, thereby achieving a more stable effect.

[0029] Operating principle and advantages: During use, the device is moved to a suitable position. The electric push rod 11 is controlled, causing the casters 12 to extend out of the outer casing 10. Once extended, the device can be moved using the casters 12. After movement, the casters 12 are moved inside the outer casing 10, bringing the base plate 1 into contact with the ground. This increases the contact area between the device and the ground, further stabilizing the device. Wastewater is then placed inside the centrifuge tank 21. The mixing motor 23 drives the mixing rod 24 to rotate, which in turn rotates the mixing blades 25, allowing the wastewater to be processed during use. After centrifugation, the wastewater is pumped to the inside of the filter tank 41 by the water pump 51. At this time, the filter motor 43 starts and drives the shaft 44 to rotate. The rotation of the shaft 44 causes the cleaning rod 46 to rotate as well. Under the action of the cleaning brush 47, the cleaning rod 46 can brush the filter disc 45, thereby preventing impurities from being adsorbed inside the filter disc 45 and affecting filtration. The rotating filter disc 45 prevents the filter disc 45 from rotating when brushed by the cleaning brush 47. Thus, under the action of multiple filter discs 45, impurities of different sizes can be filtered in layers, so that impurities in the wastewater can be accurately detected separately.
