Plate and frame filter press is a kind of equipment widely used in the production process of silicone oil, and its main function is to separate the suspension in the production process of silicone oil from solid liquid. This article will introduce in detail the application of plate and frame filter press in silicone oil production and its importance.
1. The structure and working principle of the plate and frame filter press.
The plate and frame filter press is mainly composed of filter plate, filter cloth, press roller, filter plate moving device, transmission device, etc. Its working principle is to use the gap between the filter plate and the filter cloth to intercept the solid particles in the suspension and realize the solid-liquid separation. The filter plate is divided into a fixed plate and a movable plate, and the movable plate can be moved up and down through the action of the press roller, so as to change the gap between the filter plate and the filter cloth to achieve different filtration effects.
Second, the application of plate and frame filter press in the production of silicone oil.
1.Silicone oil production process.
The production process of silicone oil mainly includes raw material feeding, dissolution, condensation reaction, fractionation and purification. Among them, the dissolution link is to mix silicate and methanol in a certain proportion to form a silicate solution;The condensation reaction is under the action of a catalyst, the condensation reaction of the silicate solution is carried out to generate crude silicone oilThe fractionation and purification process is to fractionate and purify the crude silicone oil to obtain high-purity silicone oil.
2.The application of plate and frame filter press in the production of silicone oil.
In the production process of silicone oil, plate and frame filter press is mainly used in the filtration process after the condensation reaction. The crude silicone oil generated by the condensation reaction will contain a large amount of catalyst and unreacted silicate, so it is necessary to use a plate and frame filter press for solid-liquid separation, and the solid impurities will be trapped on the filter plate to obtain a pure silicone oil liquid.
3. The importance of plate and frame filter press in silicone oil production.
1.Improve the quality of silicone oil products.
Through the filtration effect of the plate and frame filter press, the solid impurities and unreacted silicates in the crude silicone oil can be removed, the purity and quality of silicone oil products can be improved, and the market demand can be met.
2.Extend the life of your equipment.
If the crude silicone oil contains too many impurities and unreacted silicate esters, it will cause corrosion and wear to the subsequent equipment, and shorten the service life of the equipment. Through the filtration effect of the plate and frame filter press, most of the impurities and unreacted silicates can be removed, reducing the damage to the subsequent equipment and prolonging the service life of the equipment.
3.Increase productivity.
If there are too many impurities and unreacted silicates in crude silicone oil, it will lead to a decrease in the efficiency of subsequent fractionation and purification, affecting the progress of the entire production process. Through the filtration effect of the plate and frame filter press, most of the impurities and unreacted silicates can be removed, and the production efficiency can be improved.
IV. Conclusions. To sum up, plate and frame filter press has very important application value in silicone oil production. By analyzing its working principle and its application in the production of silicone oil, it is possible to better understand its importance in the production of silicone oil. In the future, with the continuous development of science and technology, the performance and efficiency of plate and frame filter press will be further improved, bringing more significant economic and social benefits to the development of silicone oil production and other fields.
