Description
Technical field
The present invention relates to a kind of sugar cane crushing and efficient filter-pressing devices.
Background technology
South China is mainly refined sugar by raw material of sugarcane, and sugarcane is carried out squeezing and is cane sugar manufacture one by sugar wash-off
Extremely important step, the squeezing hydro-peening of sugarcane are directly related to the height of sucrose yield.But existing sugar cane crushing is general
All it is single-stage squeezing, is extremely difficult to higher squeezing sugared rate, sugar residual is also more in bagasse.Therefore, by sugarcane into
Row effectively squeezes and coordinates hydro-peening, improves squeezing sugared rate with this, there is more important practical value to cane sugar manufacture industry.
It is step essential in cane sugar manufacture industry by sugar-cane juice progress press filtration, by cane milling after the completion of squeezing
Obtained sugar-cane juice often contains the insoluble solid impurities such as pectin, cellulose, needs to remove these solid impurity press filtrations, no
Subsequent sugar refining technology can then be had an impact.
The press filtration of sugar-cane juice, typically plate and frame type filter-press, and select centrifugal pump as filter pressing pump, pressure-filtering process is to obtain
Filtrate is obtained, while filter residue gradually runs up to most suitable filling degree in filter press, then carry out respective handling, finally completes filter
The circulate operation process of slag cleaning, the purpose of press filtration are exactly to realize to be separated by solid-liquid separation.In the starting stage of press filtration operation, due to press filtration
It is complete empty in machine, for filter pressing pump, the quick big flow input for carrying out smaller lift is that press filtration operates at this time
Ideal operation state；But resistance increases after being accumulated in filter press with filter cake, there is maximum pressure when especially being terminated close to press filtration
Power expanded state, therefore, press filtration the second half can have larger lift be by the press filtration performance of filter press perform to it is best must
Need condition.
But in press filtration operation, existing centrifugal pump can not all adapt to such process automatically, reach efficient, high-quality reason
Think working condition.All it is that press filtration early stage lift is relatively low, but flow is big, and motor is made to be in when general centrifugal pump carries out press filtration operation
Overload is particularly easy to burn motor；To the press filtration middle and later periods, press filtration resistance increases rapidly, and the flow quantity of centrifugal pump subtracts rapidly
Small, at this moment although motor is operated in the low power state of underloading, but efficiency of press filtering is very low；Although filter pressing pump has H-Max output
State, but since press filtration flow quantity is smaller, is unable to give full play the working performance of filter press and improves working efficiency.
Therefore, for centrifugal pump coordinates filter press, sugar-cane juice press filtration whole process is made all to reach ideal operation state, plays press filtration
Optimum performance be difficult to realize, but if looking for another way, using the free switching device of two centrifugal pump series and parallels come complete
It works at press filtration, so that it is centrifuged parallel connection of pumps by two in press filtration early stage, realize quick, low energy consumption, the efficient press filtration of big flow；Press filtration
In after the stage by two centrifuge series connections of pumps, obtain high lift conveying capacity, journey press filtration resistance is big after satisfaction, but still can have suitable
The characteristics of flow embodies efficient press filtration and gives full play to filter press performance, using such double centrifugal pump series and parallel free switchings
Device breaks through the pressure filtering technique bottleneck of sugar-cane juice, reaches the ideal operation state of press filtration, has especially important practical application
Value.

Bottom structure with back taper, bottom bevel are provided with ultrasonic vibrator；Outlet pipe connects sugar-cane juice filter press；Sugar-cane juice is slow
Tank connection three-level is rushed to squeeze the juice and adverse current jetter.
The three-level is squeezed the juice and adverse current jetter includes three groups of two pairs of rollers squeezers, and it is defeated to be equipped with vibration below two pairs of rollers squeezer
Sieve is sent, liquid dish is equipped with below vibrating conveyor screen；Three groups of two pairs of rollers squeezers and vibrating conveyor screen are in continuous ladder-like distribution；
Originally water sprayer tube carries out water spray infiltration to the bagasse that two level is squeezed and carries out third level squeezing again, is connect by the third level under liquid phase drip
Liquid disk is collected, and is transported to second level liquid dish by third level pump, mixing two level pressed liquor is pumped by the second level and conveyed, a part
It is assigned to first order liquid dish another part and water spray infiltration is carried out to the bagasse that level-one is squeezed by dilute liquid glucose spray tube, first
Grade liquid dish is conveyed after collecting pressed liquor with first order pump, and following process processing is carried out.
The present apparatus is by swivel tee cock, it can be achieved that the free switching of two centrifugal pump series and parallel structures, can make sugarcane
The press filtration operation of juice reaches optimum Working；Three-level is squeezed the juice and what adverse current jetter effectively increased cane milling goes out sugar
Rate reduces waste.
Compared with prior art, beneficial effects of the present invention also reside in：
Reach the optimum working performance of centrifugal pump needed for sugar-cane juice press filtration by the series and parallel switching of centrifugal pump；Pass through conjunction
Managing succinct circuit design and three-way cock realizes the series and parallel free switching operation of two centrifugal pumps；With conventional string, simultaneously
Union road valve switching device is compared, and threeway plug valve can greatly reduce the dosage of pipeline and valve, and simplify cutting for series and parallel
Operation is changed, the mistake occurred in common pipe valving series and parallel handoff procedure is avoided；The cone bottom of back taper and its ultrasonic wave
Vibrator can effectively prevent the blocking of sugar-cane juice surge tank, be conducive to the press filtration of sugar-cane juice.
By three-level squeezing, hydro-peening improves sugared rate twice, effectively reduces the sugar content in bagasse, than single pressure
It squeezes and improves sugared rate 20%-30%, be effectively utilized resource, reduce waste.
The configuration of the present invention is simple, it is at low cost, it is highly practical, it has a extensive future.
