How efficient is the fully automatic filter press?

 The filter press is a solid-liquid separation equipment widely used in various industries. However, the traditional filter press has a low degree of automation, a large waste of manpower and high maintenance costs. Therefore, in recent years, fully automatic filter presses have been developed on this basis, including fully automatic belt filter presses, fully automatic plate and frame filter presses, etc. So, how efficient is the fully automatic filter press?

 

First of all, the fully automatic filter press has a relatively high degree of automation. Unlike ordinary filter presses, which require manual unloading of mud cakes, continuous cleaning of filter cloth, filter plates, etc., it starts from compressing the filter plate, feeding the filter, pulling the plate, and vibrating to discharge the material. Fully automatic operation from transportation to filter cloth cleaning and regeneration. In the field of sludge dehydration, the fully automatic filter press can independently complete the entire process of sludge dehydration without manual operation. Therefore, the sludge treatment cycle can be accurately controlled and the sludge treatment efficiency can be increased by more than 70%.

 

For sludge disposal projects using fully automatic filter presses, only one person is required to monitor multiple pieces of equipment. Therefore, labor costs are greatly saved and sludge treatment costs are effectively reduced. Simplify the sludge treatment procedure and reduce the sludge with a moisture content of 96%-98% to less than 50% through chemically modified special press filtration. Modification starts from sludge with a moisture content of 98%, so the sewage treatment plant does not need belt machines, centrifuges and flocculants for pretreatment. In addition, the environment of the concentrated sludge transportation site using pumps and pipelines has been greatly improved, and the treatment cost is equal to that of the pretreatment stage.

 

The entire treatment process is operated in a cold state and does not require a heat source; the dewatered sludge will no longer be restored when exposed to water and is hydrophobic, and the water will continue to evaporate in a natural state. The moisture content can be reduced to 40%, and the mud cake will naturally break into granular shapes; the entire The system has a high degree of automation, parameter input, full automatic control operation, and assembly line production; the treatment cost is low, the amount of sludge conditioning reagent added is small, and energy consumption and labor costs are saved, thereby reducing the comprehensive sludge treatment cost of the automatic filter press by more than 70%. .

 

The use of fully automatic filter presses for concentrate dehydration has also achieved very good results. Due to the high concentration of ore, increased corrosiveness, and frequent opening and closing of the valve, issues such as the wear-resistant life of the valve, the service life of the filter cloth, and the sensitivity and reliability of the electrical control cabinet must be taken seriously. At present, fully automatic equipment cannot completely replace traditional concentrate dehydration equipment. Flocculants, filter aids, etc. are still indispensable in concentrate dehydration and still occupy an important position. An efficient fully automatic filter press must have a reasonable dehydration process in order to exert its technical advantages.

Comparison of filter press selection, which one has more advantages in treating sludge?

图片
  Now, no matter which industry it is, and no matter what kind of  sludge treatment equipment  is needed, filter press is indispensable after all, because whether it is to compress the sludge first or to transport the sludge, it still needs to be processed. The effect of dewatering sludge will be better than that of dewatering sludge, because only  filter press equipment  can effectively utilize the sludge and meet environmental protection standards after filtration. For example, some sludge is filtered and the filtrate becomes clear water, which can be directly It is recycled again. As for the filtered mud cake, some are landfilled and incinerated, and some are recycled and reused, depending on the needs of various industries, and only filter press equipment can achieve these. Therefore, users are dazzled when it comes to filter press selection, because not every filter press can achieve low filter cake moisture content and high filtration speed. Today we will ...

Which industries use high-pressure membrane filter presses?

图片
Ordinary  chamber filter presses  are suitable for most industries. The normal moisture content of the mud cake is about 75%, while the normal moisture content of the mud cake of high-pressure membrane filter press is about 65%, depending on the materials and processes. The  diaphragm filter press  is a filter press with a diaphragm plate and a chamber filter plate arranged alternately to form a filter chamber. It is a filter press with an elastic membrane installed between the filter plate and the filter cloth. The solids and liquids in the slurry are separated through the filter media (filter cloth). When the solids in the slurry form a cake, air or water is passed into the membrane filter plate to fully squeeze the solids in the filter chamber and reduce the moisture content. Generally, this filter press can be used for materials with higher viscosity and users with higher moisture content requirements. During use, when the feeding is completed, high-pressure flui...
