What are the key factors that endanger the discharge rate of the diaphragm filter press?

The analysis of diaphragm filter press is mainly concentrated in the drainage method and discharge rate of filter press, fluidity blowing filter cake and other levels, discharge rate and even more than the middle and lower reaches, work capacity line of sight.

The whole process of working pressure filtration is divided into feed filtration and tamping filtration. However, the key stage that endangers the output power of the feed method of the diaphragm filter press and the volume of the diaphragm filter press is during the feed filtration period, especially for raw materials that cannot be filtered, such as mortar with high clay composition and silt in large cities. The feed time usually accounts for 60% of the total filtration cycle time. Therefore, the focus of increasing the volume of the filter press is how to increase the feed.

In coal mines, the filter press is the latter machine equipment used to solve the viscous sludge. Ensure the mucus is thoroughly recycled. The tubular filter press used to solve the flotation reagent clean coal and pulverized coal has isolated extrusion and strong working pressure fluidity. and other roles.

Together with the single pump method, there is also a defect, that is, at the beginning of the feed, there will be a very large material friction resistance, and with the development of the feed, the friction resistance is getting larger and larger, and the corresponding underwater concrete working pressure of the pump is also higher. In conclusion, the filter cake layer produced on the surface of the filter cloth of the filter press is destroyed, the filtered pulp is lifted, and the leachate water is turbid.

Because of the low water content of the filter cake, the filter press can be fully automatic intermittent actual operation, has been widely used in anti-seepage geomembrane, light industry, chemical plants and other mining. Most of the underwater concrete and feed raw materials come from separate pumps. In other words, according to the data flow and total flow of the feed pump required by the filter press, the pump with high total flow and rising power is selected. The structure is simple, the construction is convenient, and the project investment is convenient.
