Recently, Tianhua Institute’s invention patent "rotational pressure filtering machine testing device, testing method and filtering machine design method" was authorized by the Cooperation Council for the Arab States of the Gulf (GCC). This is the first time that the company has been granted a GCC patent, marking a new step in its science and technology management, innovation, R&D and intellectual property development.
Rotary pressure filtering machines are the company’s pillar product, which is widely used in many industries, especially in the PTA industry where the demand is higher. As the machine is affected by the difference of material properties, the material properties need to be tested during design and selection. In most cases at present, material property testing is carried out on a small testing machine which is scaled down in equal proportions to large industrial rotary pressure filtering machines. Therefore, it is necessary to design and manufacture a small testing machine in advance. Even for small testing machines, various parts including the transmission system, etc. are indispensable, both the structure and process are complex, and the manufacturing cost is high. Moreover, some materials have special properties and need to be washed and dried several times. Due to the small size and structure of the testing machine, it is impossible to design many functional areas on it, so it is difficult to fully simulate the material requirements and obtain accurate design parameters for special materials.
The company’s invention patent "rotational pressure filtering machine testing device, testing method and filtering machine design method" has satisfactorily solved the problem that accurate slurry test parameters cannot be obtained by using a small testing machine, and can well meet the requirements of industrial design. It is suitable for the testing of PTA, CTA and other materials on rotary pressure filtering machines, with the advantages of short process, simple equipment and easy testing. The device can also simulate the actual operation of each process according to material properties, and analyze and evaluate each process independently. By connecting several simple devices together, it is possible to completely simulate one or several working processes on a complex device with accurate and reliable results.
The GCC Patent Office (GCCPO) is a regional patent office whose member countries include the United Arab Emirates, Oman, Bahrain, Qatar, Kuwait and Saudi Arabia. The authorization of this patent will facilitate the promotion and application of Tianhua Institute's rotary pressure filtering machines in the Middle East, and provide strong support for the company to broaden its market and build its core competitiveness.
