A vacuum belt filter is a high-efficiency solid-liquid separation equipment that can be used to process a variety of different materials. The following are the characteristics, chemical formulas, specific gravity and processing capacity of common materials such as calcium carbonate, calcium sulfate dihydrate and calcium sulfate:
Calcium carbonate (CACO
Characteristics: Calcium carbonate is a white solid, insoluble in water, with a large surface area and good adsorption properties.
Chemical Formula: CACO
Specific gravity: 271g/cm³
Processing capacity: According to the specific nature of the material and the processing requirements, generally speaking, the processing capacity of the vacuum belt filter can be adjusted within a certain range(See calculation formula for details).
Calcium sulfate dihydrate (CASO2ho）：
Properties: Calcium sulfate dihydrate is a white crystal, commonly known as gypsum. Soluble in water, it has high solubility and good ion exchange properties.
Chemical Formula: CaSO·2HO
Specific gravity: 232g/cm³
Processing capacity: According to the specific nature of the material and the processing requirements, generally speaking, the processing capacity of the vacuum belt filter can be adjusted within a certain range(See calculation formula for details).
Calcium sulfate (CASO
Characteristics: Calcium sulfate is a white solid, slightly soluble in water, with a small surface area and good adsorption properties.
Chemical Formula: Caso
Specific gravity: 296g/cm³
Processing capacity: According to the specific nature of the material and the processing requirements, generally speaking, the processing capacity of the vacuum belt filter can be adjusted within a certain range(See calculation formula for details).
Calculation:
The processing capacity of each material is usually determined based on factors such as the mode of operation, the nature of the material, the washing requirements, and the dryness requirements. Generally speaking, the processing capacity and selection of the vacuum belt filter can be calculated by the following formula:
.ProcessingCapabilitiesFilter widthCake thicknessVehicle speedSpecific gravity of the pileDischarge dryness
Among them, the thickness of the filter cake needs to be selected according to the nature of the material and the processing requirements of the appropriate filter cloth and the corresponding speed, and then the optimal thickness is adjusted according to the requirements of the dryness of the discharge. Vehicle speed needs to be determined according to experimental measurements or experience, and, within a certain range, there is a positive and negative correlation between vehicle speed and thickness and dryness.
The filtration width is considered according to the conventional model, accessory model, washing requirements, site space, transportation restrictions, processing capacity and other factors.
In summary, it can be seen that the factors involved in equipment selection are very complex. Based on the known factors above, we can derive a simple formula for the device model:
Device model, daily processing capacity, daily working hours, processing capacity.
This formula can only calculate the filtration area of the equipment, and the selection of the final model also needs to be based on the following conditions:
Equipment selection:
Although we chose the model of the equipment, due to the constraints of the use site, transportation restrictions, washing requirements and other factors, we had to consider the width, length and height of the equipment while ensuring the filtration area and processing capacity. Adjustments can be made within a certain range to achieve customized machining.
It should be noted that:The processing capacity, dryness requirements and calculation methods of different materials will vary greatly or slightly, so more detailed and accurate calculations need to be finalized according to the experimental conditions and other constraints of various materials.
