(1) Fully enclosed system, the operating environment is quite good, especially suitable for filtering and washing toxic, flammable and explosive dangerous products and delicious food biological products, pharmaceuticals and biological products that do not allow pollution.
(2) Continuous operation with extremely low labor intensity. The operation is flexible, and the operation cycle can be adjusted by adjusting the filter pressure difference, rotation speed, screw extrusion lead, etc., so as to adapt to the change of process conditions.
(3) It can not only concentrate, but also press filter. Especially when it is necessary to wash the material, the material can be concentrated first, and thoroughly washed in the suspension state, and then press-filtered, which can reduce the handling of the material, reduce waste, and do not need to re-pulp during washing. The product quality is very high.
(4) The machine can form a very thin filter cake on the surface of the filter medium or filter under the condition of no filter cake. The filtration rate per unit filter area is very high, so the equipment is small and compact.
(5) The materials can be repeatedly filtered and washed conveniently, so that the functions of multiple unit equipment can be completed on one machine, so that the equipment cost, floor area, labor intensity, energy consumption, etc. are greatly reduced. At the same time, the combination of cylinder-cone filter and wash is especially suitable for high washing requirements, and the filtered materials need to be repeatedly repulped and washed, and can save washing liquid.
(6) Make the material undergo pressure filtration under higher pressure, and vacuum filtration can also be carried out.
A jacket is added to the outside of the filter to heat, cool or heat-preserve and filter the material to meet the requirements of various process conditions.
