Description
Technical field
The present invention relates to and a kind ofly will carry out the device of efficient press filtration after sugar cane crushing.
Background technology
South China is mainly that raw material is refined sugar with sugarcane, and being carried out squeezing by sugarcane and being washed out by sugar is cane sugar manufacture very important step, and the squeezing hydro-peening of sugarcane is directly connected to the height of sucrose yield.But existing sugar cane crushing is all generally single-stage squeezing, be difficult to reach higher and squeeze out sugared rate, in bagasse, sugar is residual also more.Therefore, sugarcane effectively squeezed and coordinates hydro-peening, improving with this and squeeze out sugared rate, cane sugar manufacture industry being had to the practical value of outbalance.
After having squeezed, sugar-cane juice being carried out press filtration is requisite step in cane sugar manufacture industry, the sugar-cane juice obtained by cane milling, often containing the insoluble solid impurities such as pectin, cellulose, needs these solid impurity press filtrations to remove, otherwise can have an impact to follow-up sugar refining technology.
The press filtration of sugar-cane juice, general is all plate and frame type filter-press, and select centrifugal pump as filter pressing pump, pressure-filtering process obtains filtrate, filter residue progressively runs up to optimal filling degree in filter press simultaneously, carry out respective handling again, finally complete the cycling process of filter residue cleaning, the object of press filtration realizes Separation of Solid and Liquid exactly.In the starting stage of press filtration operation, owing to being complete empty in filter press, concerning filter pressing pump, the quick large discharge input carrying out less lift is the ideal operation state of now press filtration operation; But increase along with filter cake accumulates rear resistance in filter press, when particularly stopping close to press filtration, have maximum pressure expanded state, therefore, larger lift can be had to be to best requirement by the press filtration performance of filter press in press filtration the second half.
But in press filtration operation, existing centrifugal pump all cannot adapt to such process automatically, reaches efficient, high-quality ideal operation state.When general centrifugal pump carries out press filtration operation, be all that the early stage lift of press filtration is lower, but flow is large, makes motor be in overload, especially easily motor damage; To the press filtration middle and later periods, press filtration resistance strengthens rapidly, and the flow quantity of centrifugal pump reduces rapidly, although at this moment motor is operated in the low power state of underloading, efficiency of press filtering is very low; Although filter pressing pump has H-Max output state, because pressing filtering liquid flow is less, the service behaviour of filter press cannot be given full play to and increase work efficiency.
Therefore, centrifugal pump is made to coordinate filter press, sugar-cane juice press filtration whole process is made all to reach ideal operation state, the optimum performance playing press filtration is difficult to realize, if but look for another way, adopt the convenient switching device shifter of two centrifugal pump series and parallels to complete press filtration work, make it in press filtration in early days by two centrifugal pump parallel connections, realize fast, low energy consumption, the efficient press filtration of large discharge; In press filtration, two centrifugal pumps are connected by after-stage, obtain high-lift conveying capacity, after meeting, journey press filtration resistance is large, but still applicable flow can be had to embody efficient press filtration and give full play to the feature of filter press performance, so convenient switching device shifter of two centrifugal pump series and parallels is adopted to break through the pressure filtering technique bottleneck of sugar-cane juice, reach the ideal operation state of press filtration, there is the actual application value of particular importance.
