Utility model content
In view of this, the purpose of this utility model is to provide a kind of fluidized bed jet mill grader structure-improved that can effectively avoid material to remain in pulverizing chamber bottom.
The utility model adopts following scheme to realize: a kind of fluidized bed jet mill grader structure-improved, comprise pulverizing chamber and be positioned at pulverizing chamber top and its grading room being connected, the top of described grading room is provided with the classification motor being tightly connected with it, in described grading room, be provided with by the motor-driven classifying turbine of classification, the sidewall of described pulverizing chamber is provided with feed pipe, the sidewall of pulverizing chamber is also evenly equipped with a plurality of air inlet pipe that are positioned at feed pipe below, pulverizing chamber lower end is provided with flat end cap, on described flat end cap, be provided with to pulverizing chamber internal projection the lug boss that matches with pulverizing chamber lower end inwall, pulverizing chamber sidewall also arranges the tilting secondary intake pipes that is positioned at air inlet pipe below, described secondary intake pipes is towards described lug boss direction air intake.
Further, described lug boss upper surface is to recessed arc surface structure.
Further, described grading room top sidepiece is provided with the discharging opening that is positioned at described classifying turbine upside, and described discharging opening is connected with whirlwind powder collector by the road.
Further, described whirlwind powder collector lower end is provided with the bucket that connects material, and a described grading room top side relative to described discharging opening is provided with clean window.
Further, described pulverizing chamber inwall is positioned at air inlet pipe exit and is provided with superonic flow nozzzle.
Compared with prior art, the utlity model has following beneficial effect: this fluidized bed jet mill grader structure-improved is improved pulverizing chamber, avoid in crushing process material to remain in the bottom of pulverizing chamber, be provided with simultaneously pulverizing chamber bottoms material is blown afloat to the secondary intake pipes that continues pulverizing, greatly improve crush efficiency, substantially realized material zero residual effect in pulverizing chamber.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment organigram;
Number in the figure explanation: 1-pulverizing chamber, 2-grading room, 3-classification motor, 4-feed pipe, 5-air inlet pipe, the flat end cap of 6-, 7-lug boss, 8-secondary intake pipes, 9-discharging opening, 10-whirlwind powder collector, 11-classifying turbine, 12-connect material bucket, 13-clean window.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the utility model be described in further detail.
As shown in Figure 1, a kind of fluidized bed jet mill grader structure-improved, comprise pulverizing chamber 1 and be positioned at pulverizing chamber 1 top and its grading room being connected 2, the top of described grading room 2 is provided with the classification motor 3 being tightly connected with it, in described grading room 2, be provided with the classifying turbine 11 being driven by classification motor 3, shown in classifying turbine 11 be Verticle vortex grading wheel, the sidewall of described pulverizing chamber 1 is provided with feed pipe 4, the sidewall of pulverizing chamber 1 is also evenly equipped with a plurality of air inlet pipe 5 that are positioned at feed pipe 4 belows, the two group air inlet pipe of described air inlet pipe 5 for being oppositely arranged; Pulverizing chamber 1 lower end is provided with flat end cap 6, on described flat end cap 6, be provided with to pulverizing chamber 1 internal projection the lug boss 7 that matches with pulverizing chamber 1 lower end inwall, pulverizing chamber 1 sidewall also arranges the tilting secondary intake pipes 8 that is positioned at air inlet pipe 5 belows, described secondary intake pipes 8 is towards described lug boss 7 direction air intakes, shown in lug boss 7 can make clout be unlikely to too much to produce and pile up in bottom, under the air intake effect of secondary intake pipes 8, the clout of accumulation is blown afloat and continues to be pulverized simultaneously.
In the present embodiment, in order to make can not produce the dead angle that can pile up clout between described lug boss 7 and pulverizing chamber 1 lower end inwall, described lug boss 7 upper surfaces are to recessed arc surface structure.
In the present embodiment, described grading room 2 top sidepieces are provided with the discharging opening 9 that is positioned at described classifying turbine 11 upsides, and described discharging opening 9 is connected with whirlwind powder collector 10 by the road.
In the present embodiment, described whirlwind powder collector 10 lower ends are provided with the bucket 12 that connects material, and a described grading room 2 tops side relative to described discharging opening 9 is provided with clean window 13.
In the present embodiment, described pulverizing chamber 1 inwall is positioned at air inlet pipe 5 exits and is provided with superonic flow nozzzle, Compressed Gas sprays high velocity air in superonic flow nozzzle phase pulverizing chamber, under the effect of high velocity air, there is impact repeatedly and collision and then reach the effect of pulverizing in material, pulverized material rises in grading room and carries out classification processing with air-flow, and the material that particle is larger returns in pulverizing chamber and continues to pulverize.In the specific implementation, described pulverizing chamber 1 sidewall can also arrange the same with air inlet pipe 5 structures and be positioned at three air inlet pipe of air inlet pipe 5 tops, after realizing abundant pulverizing, enters grading room 2.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; institute is understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
