Mainly there is following defect in the existing raymond mill of said structure: grinding roller, grinding roller support etc. rotate and cause the Dual-Phrase Distribution of Gas olid of rising to rotate, pulverized solid-phase material is made to be subject to centrifugal action, be affixed to barrel, and cause material to cross pulverizing along the barrel disintegrating area that falls back, reduce crush efficiency.
Summary of the invention
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of raymond mill deflector, can reduce material and crosses pulverizing and improve crush efficiency.
For solving the problems of the technologies described above, the deflector of the raymond mill that the utility model provides, comprises the outer cylinder body be located at above support, and grader is equipped with at the top of outer cylinder body, and the classifying turbine of grader is positioned at outer cylinder body inner cavity top; Its design feature is: the inner barrel being provided with both ends open in described outer cylinder body, and inner barrel and outer cylinder body link together and leave radial clearance therebetween thus form reflux passage; On the internal face of inner barrel, spacer ring is furnished with the deflector that polylith is vertically arranged, and inner barrel lower end is higher than outer cylinder body lower end.
The material of dishing out to be conducive to being graded impeller enters reflux passage, and described inner barrel is made up of the straight section of bottom and the cone section on top.The setting of top cone section can make reflux passage top form one to expand district, be more conducive to material and enter reflux passage.
Reflux passage is entered in order to more be conducive to the flow direction of material classifying turbine after pulverizing and be graded the material that impeller dishes out, described classifying turbine lower end is arranged near inner barrel upper port, or classifying turbine lower end is stretched in inner barrel to desired location through inner barrel upper port.
The utility model is provided with inner barrel in outer cylinder body, the internal face pressed on ring of inner barrel is furnished with the deflector that polylith is vertically arranged, when Raymond mill runs, Dual-Phrase Distribution of Gas olid rotates and rises to air deflector, under the effect of deflector, be cut into non-rotary Dual-Phrase Distribution of Gas olid straight up, can effectively reduce by the sedimentation of the material pulverized, reduce material and cross pulverizing, thus improve crush efficiency.
In sum, the utility model has the advantage of: can reduce crossing of material and pulverize, crush efficiency is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the syndeton schematic diagram of inner barrel and outer cylinder body.
Detailed description of the invention
As shown in Figure 1, raymond mill comprises support 1, the top of support 1 is provided with outer cylinder body 2, grader is equipped with at the top of outer cylinder body 2, grader is existing product, specifically can adopt the grader of following structure, it comprises and is connected to outer cylinder body 2 top box 23, cabinet 23 is provided with import and outlet 28, the import of cabinet 23 and outer cylinder body 2 inner space, be connected with grading shaft 24 in cabinet 23, grading shaft 24 be equipped with the classifying turbine 3 being positioned at outer cylinder body 2 inner cavity top, grading shaft 24 is connected with classification motor 25 power be connected on cabinet 23.Axial through chamber and axially extending bore is provided with in support 1, axially extending bore is made up of the hole section from four different-diameters that are lower and that set gradually, by lower and on be followed successively by aperture section, secondary aperture section, secondary macropore section and macropore section, thus form three, upper, middle and lower step, axle bed 4 is connected with in support 1 inner chamber bottom i.e. time aperture section, main shaft 5 is rotatably connected in axle bed 4, outer cylinder body 2 inner chamber is stretched in main shaft 5 upper end, lower end passes support 1, and main shaft 5 lower end is used for namely pulverizing motor (omitting in figure) power with drive unit and is connected.Main shaft 5 upper end is connected with grinding roller support 6, grinding roller support 6 is hinged with many shaft of grinding rollers 7, and grinding roller 8 is equipped with in the lower end of described shaft of grinding roller 7.Be connected with in support 1 inner chamber top and macropore section and can coordinate to realize the bull ring 9 of crushing material with described grinding roller 8.The chamber section of support 1 inner chamber between bull ring 9 and axle bed 4 i.e. time macropore section is shovel material chamber 10, is provided with to be fixed on main shaft 5 and outward flange is connected with the perching knife rotating disk 11 of perching knife 12 in shovel material chamber 10.
