In the daily industrial production of horizontal belt vacuum filters, a common issue is how to choose a filter cloth that is suitable for one's own industry. How to select filter cloth for different types of filter presses? Let's discuss these issues! Generally, we select the filter cloth for box-type filter presses based on our standards and the characteristics of the filtering device, namely the detachment of materials, as well as their chemical and physical properties; the drying characteristics of the filter cake after filtration; and the area of the substances to be filtered is very large. We will explain each of these one by one. The first step, which is most important for us, is to consider the nature of the filtered material. This factor accounts for more than 75% in the selection of filter cloth for plate and frame filter presses.
1. The detachment characteristics of the filter residue can directly reflect the working efficiency of the filter press equipment. The surface of the filter residue is smooth and non-sticky, allowing the filtrate to quickly pass through the filter cloth, resulting in a longer filtration cycle and higher efficiency. Conversely, if the filter residue is sticky, the filtration time will increase, and thus the rate will naturally decrease. Additionally, the stronger the adhesion, the lower the rate. In this case, we will choose monofilament filter cloth or satin woven filter cloth.
2. Select filter cloth based on the chemical properties such as the acidity and alkalinity of the filtrate, choosing the most suitable filter cloth according to different levels of acidity and alkalinity. Polyester filter cloth has strong acid resistance, while vinylon filter cloth has strong alkali resistance. Polypropylene filter cloth is resistant to both acid and alkali.
3. The style of the filter residue, the uniformity of the particles, and the hardness of the style should be considered to evaluate the wear resistance of the filter cloth. They vary in size and may have sharp edges, and they are selected based on different levels. Good wear resistance is found in striped filter cloth and economical filter cloth.
4. The temperature of the filtering device also affects the working efficiency of the filter press. Heat-resistant fabrics are striped filter cloth.

How to choose the filter cloth for a horizontal belt vacuum filter?
In the daily industrial production of horizontal belt vacuum filters, a common issue is how to choose a filter cloth that is suitable for one's own industry. How should one select the filter cloth for different types of filter presses?
The application range of horizontal belt vacuum filters.
The horizontal belt vacuum filter is a type of efficient solid-liquid separation equipment that uses filter cloth as the filtering medium. It flexibly utilizes the gravitational force of the raw materials and vacuum suction to achieve solid-liquid separation.
Precautions for Vacuum Filter Machines
In the process of properly filtering waste liquid, a vacuum filter is indeed indispensable. This is mainly because it effectively utilizes vacuum pressure to perform its work, and its operation skills are simple and easy to master, which is why it is favored by many people.
The reasons for the non-sealing of a horizontal belt vacuum filter.
What causes a horizontal belt vacuum filter to become unsealed? During the operation of a filter press, there are times when it encounters sealing issues, which can affect the operation of the equipment and pose safety risks in the production process. So, what leads to such situations? Here, we summarize several aspects. Let's take a look.
What are the technical characteristics of a vacuum belt filter?
The vacuum belt filter press uses a vacuum box and a lifting device to connect sections into a whole, forming a vacuum liquid collection system, which is widely used.
Maintenance of Vacuum Belt Filter during Shutdown
If the internal energy of the filtrate in a vacuum belt filter increases, the liquid will also exert pressure on the filter plate. If the filter plate cannot withstand this pressure, the filtrate will inevitably leak out through the gaps in the filter plate, significantly reducing the original internal energy of the filtrate. Therefore, the equipment needs to provide pressure to the filter plate, with the pressure being greater than the counteracting force of the filtrate on the filter plate, thus ensuring that the filtrate maintains a high internal energy, which in turn improves the filtration effect.
