Abstract
The present invention discloses a centrifugal pressure sedimentation dewaterer of an annular filter-pressing working chamber. The inner wall of the annular filter-pressing chamber is connected with a screen drum, and the outer wall is connected with a sedimentation cylinder. Liquid containing materials in the filter-pressing chamber not only is subjected to the action of centrifugal force, but also is subjected to the action of impressed pressure, and thus, the dewaterer organically and integrally combines filter pressing and sedimentation and simultaneously works. Consequently, the purposes of continuous filter pressing, continuous precipitation and continuous dewatering are achieved. Accordingly, the dewaterer of the present invention has the advantages of high efficiency, small volume, low energy consumption and simple structure. A screen drum is replaced into a filter cylinder, a filter net or filtering cloth is fixed on the filter cylinder, and solid and liquid are separated step by step. The requirements of actual production work can be satisfied by the same type, and a purpose of positive cycle work is achieved.
Description
The present invention relates to the centrifugal filter press sedimentation dewatering machine of an annular press filtration working cavity, especially be applied to a kind of solid-liquid separation mechanics equipment in the solid-liquid separation technique field.
At present, the dewatering machine that is applied in the solid-liquid separation technique field has centrifugal dehydrator, vacuum filter, filter press etc., its operation principle is: moisture material is added on the compass screen surface, because water-containing materials is subjected to centrifugal force, difference force, so pressure is to just there being a normal pressure on the compass screen surface, solid particle is deposited on the compass screen surface, liquid is then discharged by the hole on solids precipitation thing and the compass screen surface, reach the purpose of Separation of Solid and Liquid, owing to adopted the dewatering machine of above operation principle, not only liquid has normal pressure to compass screen surface, and also there is bigger normal pressure in solid particle to compass screen surface, so cause the liquid-through hole on the compass screen surface to stop up, solid particle forms a kind of resistant layer on compass screen surface, especially to the Separation of Solid and Liquid of molecule, efficient is low, volume is big, energy consumption height, complex structure, type is many, so can not well satisfy the actual production requirements of one's work.
Task of the present invention provides the continuous operation of a kind of energy, and the not susceptible to plugging centrifugal filter press sedimentation dewatering machine of screen cloth.
In order to solve above-mentioned task, the solution that the present invention adopts is: a screen drum is installed in settlement barrel, settlement barrel madial wall and the formed annular housing of screen drum lateral wall are the press filtration operating room, press filtration chamber one end annular mouth is a charging aperture, other end annular mouth is a discharging opening, when settlement barrel and the rotation of screen drum synchronous high-speed, just there is a centrifugal force field in the press filtration operating room.The material that contains liquid when the pump handle, pass through pipeline, the feed pipe anchor tip, feed shaft, it is indoor that centrifugal material guiding plate is sent into press filtration, the material that contains liquid is under the effect of centrifugal force field, solid particle is deposited in rapidly on the settlement barrel inwall, the lip-deep liquid of screen drum is under the effect of pressure, overcome centrifugal action, enter on the inboard wall of riddle drum by the screen drum hole, and be thrown in the water leg by outlet pipe, precipitated solid particle on the screen drum along inwall, under action of centrifugal force, in time radially move on the settlement barrel inwall, so solid particle under pressure and action of centrifugal force, moves to the discharging opening direction, and closely knit gradually, reach the purpose of dehydration.Solid material after the dehydration relatively rotates by helical rotor and guide tube, is directed at guide tube lower end, is thrown in the material collecting tank at last.Because of solid particle is deposited on the screen drum lateral wall, so screen drum can not cause the solid particle clogging, screen drum is fully contacted with liquid, thereby reach the purpose of dehydration.Centrifugal filter press sedimentation dewatering machine of the present invention because of the press filtration operating room is an annular housing, and can rotate at a high speed, the indoor material that contains liquid of press filtration, not only be subjected to action of centrifugal force, also be subjected to the effect of pressure simultaneously, sedimentation and press filtration are organically connected, and work simultaneously, thereby reach continuous filter press, continuous sedimentation, the purpose of continuous dehydration, thereby as can be known, high heart filter press sedimentation dewatering machine efficient height of the present invention, volume is little, and energy consumption is low, simple in structure, screen drum is also replaceable to be filter cylinder, and fixedly upper filter screen or filter cloth on the filter cylinder surface are carried out step by step solid-liquid and to be separated, just can satisfy the actual production need of work with a kind of type, reach eucyclic work purpose.
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
