Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
A kind of dentation formula pressurize filter-pressing method, comprise pre-compaction process, fill process, single pressing process and twice pressing process, described twice pressing process is segmentation dentation formula press dewatering process, drive hydraulic cylinder action that the force value in each segmentation is increased gradually, when squeeze pressure value reaches the first force value of setting, drive hydraulic cylinder action squeeze pressure value to be reduced to the second force value of setting, enter next segmentation.
To in the press dewatering process of material, the pressure influence of press filtration the press dewatering effect to material, therefore will control the pressure of described hydraulic cylinder well, and material can be dewatered more fully between filter press plate.In the prior art, the patent No. is 201610066545.7 pressing methods disclosing by variable displacement type filter press, it is divided into multiple segmentation press dewatering process in the process of twice pressing, each segmentation is pressurize dehydration certain hour under the force value of setting squeezing, in this pressurize dewatering time process, squeeze pressure declines because being squeezed thing dehydration, when squeeze pressure value drops to the pressure difference value of setting, the squeeze pressure value that hydraulic cylinder action reaches setting proceeds press dewatering, until the squeezing time of this setting stepwise, enter next segmentation press dewatering process, and a kind of dentation formula pressurize filter-pressing method that the present invention proposes, unlike in twice pressing process, described twice pressing is set to segmentation dentation formula press dewatering process, and in each segmentation, set the first force value and the second force value, when squeeze pressure value reaches the first force value of setting, hydraulic cylinder action is driven squeeze pressure value to be reduced to the second force value of setting, enter the second segmentation again, therefore its state making the pressure of described hydraulic cylinder can be in dentation formula to increase steadily, avoid the unstability of above-mentioned prior art cylinder pressure, and make material and filter press plate obtain necessarily of short duration buffering course in the process be squeezed, certain protective effect is played to filter press plate, greatly improve described material dewatering effect, dehydration is stablized, high and the saving resource of dewatering efficiency.
Further illustrate, each first force value in the expressing process of described each segmentation increases from front to back piecemeal, and the increment of the pressure of each segmentation is identical, and the whole pressure change difference in described twice pressing process is 110-250kg.
When carrying out twice pressing; sealing property between described filter press plate can be subject to certain punching press; if moment or unstability ground supercharging; often cause the destruction of multiple pressure filter plate, affect its sealing property etc., therefore the first force value of the squeezing of each segmentation is increased from front to back piecemeal and pressure increment identical; can dewater more fully; make to material squeezing effect more fully, evenly, and can filtering equipment be protected, extend its service life.
