[detailed description of the invention]
Can explain the present invention in more detail by the following examples, the present invention is not limited to the following examples;
A kind of central shaft with dual channel by reference to the accompanying drawings described in 1 ~ 4, comprise center shaft body 1, central shaft internal partition 3, check valve 4 and central shaft supervisor 5, the outer edge surface of center shaft body 1 is provided with the fanning strip 2 of at least one row's circular array, described fanning strip 2 of often arranging is made up of a plurality of fanning strip 2, wherein center shaft body 1 is hollow structure, central shaft supervisor 5 is interval with in the endoporus of center shaft body 1, in the cavity between the outer edge surface and the inner edge surface of center shaft body 1 of central shaft supervisor 5, be interval with the outer steel plate 6 of a plurality of supervisor or be provided with the outer pipe 7 of a plurality of supervisor, the two ends of the outer steel plate 6 of described each supervisor connect central shaft supervisor's outer edge surface of 5 and the inner edge surface of center shaft body 1 respectively, two outer edge surfaces up and down of the outer pipe 7 of described each supervisor connect central shaft supervisor's outer edge surface of 5 and the inner edge surface of center shaft body 1 respectively, and form the runner of central shaft by the middle part endoporus of pipe 7 outside the cavity between every two outer steel plates 6 of supervisor or each supervisor, between every two outer steel plates 6 of supervisor, be provided with central shaft internal partition 3 or be provided with central shaft internal partition 3 in the endoporus of the outer pipe 7 of each supervisor, described each central shaft internal partition 3 is separately positioned on one end of cavity between every two outer steel plates 6 of supervisor of central shaft supervisor 5, each central shaft internal partition 3 makes the cavitys between every two outer steel plates 6 of supervisor form two-layer independently cavity up and down or be separately positioned in the endoporus of each supervisor pipe 7 outward of central shaft supervisor 5 at each central shaft internal partition 3, each central shaft internal partition 3 makes the endoporus of the outer pipe 7 of each supervisor form two-layer independently cavity up and down, each central shaft internal partition 3 is respectively equipped with check valve 4 and forms the described central shaft with dual channel.
The specific embodiment of the present invention is: the cavity that the present invention makes central shaft be responsible between the outer edge surface of 5 and the inner edge surface of center shaft body 1 by the outer steel plate 6 of a plurality of supervisor forms one group of fan-shaped cavity, or the outer pipe 7 of supervisor of a plurality of equal diameter is set in the cavity between the outer edge surface and the inner edge surface of center shaft body 1 of central shaft supervisor 5, the hole communicated with it is radially all had further in each fan-shaped cavity or circular cavity, wherein each fanning strip 2 just inserts in this hole, in the cavity between the outer edge surface and the inner edge surface of center shaft body 1 of central shaft supervisor 5, no matter be fan-shaped or circular cavity all uses central shaft internal partition 3 to be divided into two in its space, its the first half is logical negative pressure of vacuum, the area needed more greatly, to realize main suction blotting work, its the latter half is as air blasting passage, area is relatively less, on central shaft internal partition 3, correspondence is equipped with a check valve 4 for 2 times at each fanning strip, this check valve 4 is in normal suction and be in closed condition when blotting work, but enter when blowing off operation, the wind fed due to operation of blowing off feeds from axle head cavity comparatively small size with certain positive pressure pressure, and check valve 4 just backs down thus enters in fanning strip 2 by the wind of malleation.
Each for filter central shaft runner can be become two runners after the invention process, when needing imbibition and blot, negative pressure of vacuum enters a runner, meets imbibition and blots operation, and the water that negative pressure is extracted out is discharged from this runner; During blowing, the wind of malleation enters fanning strip 2 from another runner, solves the water can not taken away completely in single channel and is blown back to fanning strip 2 again, makes the filter cake of filtration drying additionally increase again the problem of filter cake moisture, can also reduce energy consumption simultaneously.
Part not in the detailed description of the invention is prior art.
The embodiment selected in this article in order to open goal of the invention of the present invention, currently thinks to be suitable for, but it is to be understood that the present invention is intended to comprise all changes belonging to the embodiment in this design and invention scope and improvement.
