Abstract
The invention discloses a centrifugal machine with a double-layer rotary drum structure. The centrifugal machine comprises a main shaft and a rotary drum connected with the main shaft; the rotary drum is divided into an outer rotary drum body and an inner rotary drum body, the inner rotary drum body is located inside the outer rotary drum body, and a cavity is formed by the side portion of the inner rotary drum body and the outer rotary drum body; the main shaft penetrates the cavity to be connected with the inner rotary drum body, and therefore the outer rotary drum body and the inner rotary drum body rotate in the negative directions; slant sliding ways are arranged on the inner rotary drum body and the outer rotary drum body and are communicated with the cavity, and a suction tube is arranged in the cavity; and a filtering medium is installed on the inner layer of the inner rotary drum body, a feeding tube, a scraper and a discharging hopper are contained in internal space of the inner rotary drum body, and the scraper is located nearby the filtering medium. Though the double-layer structure of the inner rotary drum body and the outer rotary drum body, solid-liquid separation is efficiently achieved, and meanwhile vibration can be effectively avoided.

Fig. 1 is a kind of perspective view with the centrifuge of double-deck drum structure disclosed in the embodiment of the present invention.Numeral and the corresponding component title represented by letter in figure: 1, main shaft; 2, outer drum; 3, interior rotary drum; 4, sluicing pipe; 5, chamber; 6, suction pipe; 7, recoil tube; 8, scraper; 9, discharge bucket; 10, filter medium; 11, inclined ramp.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
A kind of centrifuge with double-deck drum structure, comprise main shaft 1, rotary drum is connected with described main shaft 1, described rotary drum is divided into outer drum 2 and interior rotary drum 3, it is inner that described interior rotary drum 3 is positioned at described outer drum 2, and meanwhile, described interior rotary drum 3 is mutually close with described outer drum 2 diametrically, between the end of described interior rotary drum 3 and the end of described outer drum 2, there is certain space, namely form chamber 5.As shown in Figure 1, described main shaft 1 is as follows with the connected mode of described rotary drum: described main shaft 1 is through described outer drum 2, enter described chamber 5, end is connected with described interior rotary drum 3, can be connected by bearing between described outer drum 2 with described main shaft 1, can rotate, be rotated by main shaft described in driven by motor 1, thus driving described interior rotary drum 3 to rotate, its rotation direction is consistent with described main shaft 1 rotation direction; Apply axial force to outer drum 2 from outside, described outer drum 2 rotates by described bearing, and rotation direction is contrary with described interior rotary drum 3 direction simultaneously.Described interior rotary drum 3 and described outer drum 2 offer inclined ramp 11, when the inclined ramp 11 on described interior rotary drum 3 and described outer drum 2 overlaps, liquid can pass through in inclined ramp 11, one end of described inclined ramp 11 communicates with described chamber 5, and liquid flows to described chamber 5 by described inclined ramp 11.At the internal layer of described interior rotary drum 3, filter medium 10 is housed, in the inner space of described interior rotary drum 3 built with a feed pipe, slip enters to described interior rotary drum 3 by described feed pipe, fall on described filter medium 10, by the filtration of described filter medium 10, described filter medium 10 can select filter screen etc., be not particularly limited at this, liquid can flow in inclined ramp 11, when described interior rotary drum 3 coincides with the inclined ramp 11 on described outer drum 2, liquid can enter in described chamber 5 along described inclined ramp 11.In order to the liquid in described chamber 5 being discharged in time, the present embodiment is provided with a suction pipe 6 in described chamber 5, when described suction pipe 6 stretches to below described filtrate liquid level, described filtrate can be subject to pressure reduction impact, discharged in the outside of centrifuge rapidly by described suction pipe 6, the more important thing is, in emptying process, a negative pressuren zone can be formed between described filter medium 10 and described chamber 5, make filtered driving force become centrifugal force and vacuum draft.In the inner space of described interior rotary drum 3, be also provided with sluicing pipe 4 and scraper 8, the solid-phase material of described interior rotary drum 3 inside, the wash water injected by sluicing pipe 4 can be washed; Simultaneously, material after dehydration and washing dry can be unloaded from filter medium 10 by scraper 8, discharge bucket 9 is provided with below described scraper 8, the top of described discharge bucket 9 is horn mouth, middle and bottom is skewed slot, described material, by entering in horn mouth, can be expelled to the outside of centrifuge along described skewed slot.At described chamber 5 built with recoil tube 7, after discharging completes, by recoil tube 7, clear water is injected in described chamber 5, clear water can flow in described rotary drum by inclined ramp 11, thus the residual material on described filter medium 10 is become loose, at the internal layer of described interior rotary drum 3, make can not produce vibration when adding material within the next operation cycle.
