Wastewater collecting device with cleaning structure for graphene preparation

Abstract

The invention relates to the technical field of graphene preparation, in particular to a wastewater collecting device with a cleaning structure for graphene preparation. The wastewater collecting device comprises a supporting foot stool, the top end of the supporting foot stool is fixedly connected with a wastewater collecting device body, and a ball bearing is inserted into the surface of the top end of the wastewater collecting device body, and a rotating disc is fixedly connected to the top end of the ball bearing, a screw rod is inserted into the surface of the top end of the rotating disc, and a threaded sleeve rod sleeves the surface of the screw rod. By arranging the filter screen, when the filter screen needs to be disassembled, replaced and cleaned, one side of the top end of the sealing plate can move downwards by rotating a fixing bolt inserted into the inner wall of the filter cavity and arranged at the top end of the sealing plate so that the inner wall of the filter cavity is opened, and a handle arranged in one side of the filter screen is pulled, the filter screen can be conveniently taken out from the interior of the filter cavity, a worker can conveniently detach, clean and maintain the filter screen, and the maintenance efficiency is improved.

[0002] At present, the preparation methods of graphene mainly include micromechanical exfoliation, epitaxial growth method, chemical vapor deposition method and solution phase preparation method. Compared with redox method, other methods are complicated to operate, harsh conditions or low yield. It is difficult to apply to the large-scale preparation and production of graphene. The redox method has a simple process and can prepare graphene in batches and efficiently. It is an effective way to prepare graphene materials on a large scale. However, in the graphite oxide purification process, there will be A large amount of acidic waste water containing acid compounds, if no effective measures are taken to deal with it, will not only pollute the environment, but also cause great harm to people's health

[0003] During the long-term use of the existing waste water collection device for graphene preparation, some dirt and acidic substances in the waste water will adhere to the inner wall of the device. If it is not cleaned in time, it will cause damage to the inner wall of the device and easily cause blockage of the device , and most of the waste water collection devices are set up as a closed structure, which makes it difficult for the staff to clean the inner wall of the device, and the cleaning environment is poor, which has a certain impact on actual use

Moreover, when the existing wastewater collection device for graphene preparation filters the impurities and dirt in the wastewater, since most of the filter screens adopt a fixed installation structure, it is inconvenient for the staff to disassemble, clean and maintain the filter screen, which increases the maintenance cost. , which reduces the maintenance efficiency. At the same time, it is installed with a fixed filter screen, which cannot vibrate the filter screen, so that the wastewater passing through the filter screen cannot be fully filtered, which affects the filtering effect. For this reason, we propose a graphene preparation with a clean structure. Wastewater collection device to solve the above problems
