Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail. NeedIllustrate, in the situation that not conflicting, the feature in the application's embodiment and embodiment can phaseCombination mutually.
As depicted in figs. 1 and 2, according to the bowl internal washing of embodiment of the present utility modelDevice comprises collecting hood 1 and multiple guide blot 2, wherein:
The front end of described guide blot 2 is arranged on the inwall of rotary drum 3 of centrifuge, described guiding spiral shellBolt 2 from front end have vertically one with the inlet opening 2 being communicated with described rotary drum 3, described guide blot 2Upper being also provided with successively along described inlet opening 21 organized apopores 22 more, and every group of apopore 22 comprises at least oneThe apopore 22 of the described inlet opening 21 of individual connection and described guide blot 2 outsides;
The rear end of described collecting hood 1 is fixedly connected with the outer wall of described rotary drum 3, and described collecting hood 1 isThe annular slab that one front end bends inwards, the distance of the front end of described collecting hood 1 and the rotating shaft of described centrifugeFrom being less than the ultimate range of described inlet opening 21 with described rotating shaft.
In this technical scheme, collecting hood 1 is fixed on the outer wall of rotary drum 3, by water inlet pipe 12Delivery port be placed on the bending place of the front end of collecting hood 1, in the centrifuge course of work, rotary drum 3 is at a high speedRotate and water inlet pipe 12 is motionless; After flowing out, the water of water inlet pipe 12 telling the band of collecting hood 1 of rotationMoving next superhigh speed rotates, and tells the water of rotation under the effect of centrifugal force, to be thrown to the inwall of collecting hood 1Upper, along the arrow circulation in collecting hood in figure 1; Along with water in collecting hood increases gradually, liquid level byGradually approach the inlet opening 21 of guide blot 2, liquid level reaches the i.e. effect at centrifugal force behind inlet opening 21Under enter in guide blot 2, remain water under the effect of centrifugal force and thrown away from each apopore 22,Thereby realize the object of cleaning guide blot 2 rotary drum 3 around.
Wherein, it should be noted that, for ensureing that current can enter in guide blot 2, need to collectThe bending place of the front end of cover 1 is nearer apart from this rotating shaft than inlet opening 21 apart from the rotating shaft of rotary drum 3, otherwiseWater will overflow from the gap between this bending place and water inlet pipe 12, or need to be to outside water inlet pipe 12Wall carries out movable sealing, and not only cost is high, and can increase the frictional force of rotary drum 3. Particularly, receiveThe bending place of the front end of collection cover 1 turns apart from this than the upper edge of inlet opening in figure 21 apart from the rotating shaft of rotary drum 3Axle nearer (being the ultimate range of inlet opening 21 and rotating shaft) can ensure that at least part of water enters guiding spiral shellIn bolt 2, and as a kind of preferred embodiment, the front end of described collecting hood 1 and described centrifugeThe distance of rotating shaft is less than described inlet opening 21 and minimum range described rotating shaft, collecting hood 1 beforeThe bending place of end is nearer apart from this rotating shaft than the lower edge of inlet opening in figure 21 apart from the rotating shaft of rotary drum 3, canTo ensure that better water enters guide blot 2 but not overflows from collecting hood 1 front end. By this technical sideCase, can realize guide blot 2 rotary drum 3 (be difficult to clean position) effectively clear aroundWash.
Further, the rear end of described collecting hood 1 inwardly or outward, after described collecting hood 1 passes throughThe bending part of end and described rotary drum 3 are fixing. In this technical scheme, collecting hood 1 rear end bends moreEasily fixing on rotary drum 3, space is saved in bending inwards as shown in FIG. more.
Preferably, described inlet opening 21 is a blind hole, can avoid the right-hand member of current from guide blot 2Pass and avoid material to enter in guide blot 2.
Preferably, described inlet opening 21 is positioned on the central axis of described guide blot 2, described water outletHole 22 is along the radially setting of described guide blot 2. Adopt Central Symmetry mechanism, process more convenient,All directions cleaning performance is more consistent.
Preferably, described in every group the quantity of apopore 22 described in apopore 22 be multiple, every groupIn described apopore 22 all on described guide blot 2, be uniformly distributed circumferentially, every group all adopts manyIndividual apopore 22 cleaning performances are better.
In a kind of detailed description of the invention, especially for two-stage material-pushing centrifuge, described rotary drum 3 comprisesOne-level rotary drum 31 and secondary rotary drum 32, described centrifuge also comprises baffle plate 4, described guide blot 2Front end be arranged on described secondary rotary drum 32, the rear end of described guide blot 2 turns through described one-levelDrum 31 is connected to described baffle plate 4, and described collecting hood 1 is arranged on the outer wall of described secondary rotary drum 32,Described at least one group, apopore 22 is between described one-level rotary drum 31 and described secondary rotary drum 32 or instituteState between one-level rotary drum 31 and described baffle plate 4.
In this technical scheme, can effectively clean the position that is difficult to cleaning in two-stage material-pushing centrifuge,Be between secondary rotary drum 32 front ends and one-level rotary drum 31 front ends, one-level rotary drum 31 front ends and baffle plate 4Between 2. In addition, collecting hood 1 is as a loop configuration, and its installation site is equivalent to cover in the drawingsOn shown sealing ring 11, but do not contact with sealing ring 11, water inlet pipe 12 is positioned at collecting hood 1And between sealing ring 11, between sealing ring 11 and collecting hood 1, form an annular gap.
