Titanium dioxide is an important inorganic pigment, which is widely used in coatings, plastics, papermaking, cosmetics and other fields. In the production process of titanium dioxide, the filter press is an indispensable equipment, which is mainly used to separate titanium dioxide and liquid mixtures. This article will introduce the application links and characteristics of filter presses in the production process of titanium dioxide.
First, the introduction of the filter press.
Filter press is a commonly used filtration equipment, which can effectively separate liquids and solids. Its working principle is mainly to form a pressure difference between the two sides of the filter cloth through pressurization, so as to separate the liquid and solid. The filter press is mainly used in the solid-liquid separation stage in the production process of titanium dioxide, that is, the titanium dioxide is separated from the liquid mixture through the filter press.
Second, the application of filter press in the production process of titanium dioxide.
1.Mixed pools.
The mixing pool is the first link in the production process of titanium dioxide, and its main function is to mix the raw materials according to a certain proportion to form a uniform slurry. In this link, the filter press is mainly responsible for the preliminary solid-liquid separation of the mixed slurry, removing large particles and impurities to ensure the smooth progress of the subsequent process.
2.Reaction tank.
The reaction tank is one of the core equipment in the production process of titanium dioxide, and its main function is to carry out chemical reaction of the mixed slurry to generate titanium dioxide. In this process, the filter press is responsible for the solid-liquid separation of the reaction solution and the separation of titanium dioxide from the solution. Due to the high viscosity of the solution in the reaction tank, a filter press with strong filtration performance is required.
3.Washing tanks.
The function of the washing tank is to wash and dry the separated titanium dioxide to remove impurities and moisture in it. In this process, the filter press is mainly responsible for dewatering the washed titanium dioxide to ensure that its water content meets the requirements. At the same time, the filter press also needs to further screen the titanium dioxide to remove the fine particles and impurities in it.
4.Wrap.
After washing and drying, TiO₂ needs to be packaged for easy transportation and use. In this process, the filter press is mainly responsible for the final inspection and treatment of the titanium dioxide to ensure that its quality and purity meet the requirements. At the same time, the filter press also needs to carry out operations such as metering and bagging of titanium dioxide.
3. The characteristics of the filter press in the production process of titanium dioxide.
1.High filtration performance.
In the production of TiO₂, filter presses need to handle a wide range of liquid and solid mixtures with different properties, so they need to have high filtration performance. Filter presses with high filtration performance can effectively improve production efficiency and reduce production costs.
2.Corrosion resistance.
Most of the raw materials and solutions used in the production of titanium dioxide are corrosive, so the filter press needs to be corrosion-resistant. The corrosion-resistant filter press can ensure the long-term stable operation of the equipment and prolong the service life of the equipment.
3.High degree of automation.
In order to improve production efficiency and reduce labor costs, the TiO₂ production process needs to be automated as much as possible. As one of the important equipment in the production process, the filter press also needs to have a high degree of automation. The improvement of the degree of automation can reduce the error and inconvenience caused by manual operation, and improve the quality and efficiency of production.
4.Easy to maintain.
In order to ensure smooth production and improve the efficiency of the equipment, the filter press needs to be easy to maintain. The easy-to-maintain filter press can reduce the failure rate and maintenance cost of the equipment, and improve the reliability and stability of the equipment.
In short, in the production process of titanium dioxide, the filter press, as an important filtration equipment, has an irreplaceable role. In order to ensure the smooth progress of production and improve the competitiveness of enterprises, it is essential to choose the right filter press and use and maintain it reasonably.
