We choose the filter type, the next one is to select the filter press filter area, Filter Plate and naturally will be concerned about the filter press filter up, in front of us on how to calculate the filter for their own filter filter Of the filter area. For the filter press filter plate in addition to considering the filter area, but also need to take into account the filter press plate thickness factor. For the filter press the thickness of the filter, Filter Plate we generally have several options range: 45mm, 60mm, Filter Plate 80mm (do not rule out in some special industries using thick or ultra-thin filter plate). We are the three different thickness of the filter press filter is what kind of design considerations.
For some industries, the filter press may be the pressure into the pressure environment will not be so big, and each piece of the filter plate area requirements will not exceed 800mm * 800mm, while the use of the filter area has a certain limit, I You can consider using a thickness of 45mm. This filter plate can make the filter press across the length of 80% reduction, but also to reduce the filter area of the filter, Filter Plate the release of a lot of space. But also to reduce the filter press load, so that the use of filter more reasonable.
For the thickness of 60mm, this is the international standard filter press plate thickness, so the thickness of a wide range of use, but also to filter the performance of the highest, not only makes the filter can be up to 25 MPa Pressure normal work, but also make the filter plate more wear, pressure, Filter Plate can withstand the impact of hard objects and pressure. And the thickness of the filter plate reached 60mm, the filter plate storage filter cake space also increased, reducing the number of times the filter press cycle, increasing the efficiency of filter press filter, while increasing the storage capacity of the filter cake, but The filter cake is applied to the gravity of the filter press and therefore does not add excessive load to the filter press. Filter Plate Is to use 60mm filter plate filter can improve the overall performance.
In the daily industrial production, will inevitably encounter some special industries use filter press, for some high pressure, or filter contains very hard solid particles, we can recommend the use of thick plate filter press , Not only increased the will of the filter plate with the ability, Filter Plate but also effectively reduce the impact of high temperature filter on the filter.
The reinforced polypropylene filter plate is added with some reinforcing agent in the polypropylene, and the coupling agent is a glass fiber modified polypropylene material treated with a coupling agent. Filter Plate So that the performance improvement: high hardness, good rigidity, high elastic modulus, linear expansion coefficient is very strong acid, alkali, temperature and other characteristics.
Our commonly used filter press plate is made of reinforced polypropylene. Filter Plate Generally white, fragrant gray or bean gray; there is a green filter press plate. It was in the production process by adding a kind of industrial dyes.
Van filter press the general thickness of the filter between 60 ~ 85mm, each filter plate are square, in the filter plate on both sides of the reduced about 40mm to the internal concave down, Filter Plate the general depression down to the depth of about 25mm, The point is also dissatisfied with a high about 8mm protrusion, can be round, you can make the bar. This is the role of the filter plate in the process of re-filtration of the filter cake produced a good contact, Filter Plate so as to support the role of cake.
Van filter press in the middle of the filter plate, also with a hole through the hole, which feed the pipe, generally in the diameter of 100mm. And in the recess below or around, Filter Plate with a drainage hole, connected with the drainage pipe, the filtered liquid discharged from the equipment. Both sides are the same. Between the filter plate and filter cloth, the general filter cloth for a set of two, Filter Plate through the middle of the filter plate through a small number of filter cloth cylinder connected, so that you can well include the filter plate.
Van filter press filter structure there are different, Filter Plate it has two kinds of filter plate structure: the general filter plate and the border of the filter plate. Border filter plate is used to insert the filter plate of the square half of the phase made. These two kinds of filter plate staggered into the frame filter press filter room.
