The specific embodiment

Broken oven dry flour mill described in the utility model, as shown in Figure 1, comprise housing 4, housing 4 can be the jar shape structure of upper diameter greater than lower diameter, discharging opening 2 is offered at housing 4 tops, on the discharging opening 2 discharge nozzle 14 can be installed, inner housing 8 is installed in the housing 4, inner housing 8 is divided into crusher chamber 18 and vented cavity 17 with the cavity in the housing 4, be crusher chamber 18 in the

inner housing

8,4 of inner housing 8 and housings are vented cavities 17, and main shaft 16 is installed in the inner housing 8, the lower end of main shaft 16 passes outside the housing 4, air inlet 19 is offered in the bottom of housing 4, on the lower sides of housing 4 air inlet duct 6 can be set, and offers air inlet 19 on the air inlet duct 6, be the flaring structure in the air inlet duct 6, promptly air inlet 19 is less than the interior end opening of air inlet duct 6.Feed pipe 7 is installed on the housing 4, feed pipe 7 upper ends are positioned at outside the housing 4, the lower end of feed pipe 7 penetrates in the housing 4 and is positioned at the top of inner housing 8, the periphery of main shaft 16 is installed charging tray 15, charging tray 15 is positioned at inner housing 8 belows, the periphery of charging tray 15 is installed several fan blades 11, and several fan blades 11 can be uniformly distributed in the periphery of charging tray 15.Fan blade 11 rotates with main shaft 16 all the time, and fan blade 11 rotates on the one hand and can will import on the wind direction of being sent into by blower fan, also can material can be risen the large granular materials addi-tional crusher with air-flow on the other hand, prevents that material from stopping up air inlet duct 6.

Every fan blade 11 all has an inclination angle with respect to horizontal direction, and all overlap between every adjacent two fan blades, but overlapping portion is not in same plane, promptly overlook charging tray 15, adjacent two fan blades 11 block mutually, do not have the vertical gap that connects, and can find out adjacent two fan blade 11 overlaids part among Fig. 1 at a certain distance between the upper and lower, thereby, can guarantee that large granular materials can't drop in the air channel 6 between two fan blades 11, prevent that large granular materials from stopping up air inlet duct 6.Fan blade 11 rotates with charging tray 15, removes to prevent that large granular materials from falling also can play the purpose of further comminuting matter, improves crushing efficiency.

Be a progressive crushing efficiency that improves, as shown in Figure 1, many vertical crushings hammers 5 can be installed on the charging tray 15, vertical crushing hammer 5 is connected with charging tray 15 vertical fixing.

For ease of reclaiming broken inadequate large granular materials, hopper 3 can be installed in housing 4, the material mouth of hopper 3 is positioned at inner housing 8 tops, after the material after the fragmentation is risen to hopper 3 tops by the air-flow drive, satisfactory material particles is discharged by discharging opening 2 under the drive of air-flow owing to quality is little, and undesirable large granular materials is because quality falls under gravity into inner housing 8 greatly, enter the next round shattering process, meet the requirements until granular size.

Carry out fragmentation once more for making undesirable bulky grain can be recovered into inner housing 8 better, can wind deflector 1 be installed in housing 4, wind deflector 1 is positioned at hopper 3 tops.As shown in Figure 1, the uniform a plurality of wind deflectors 1 in the top of housing 4, each wind deflector 1 all can be adjusted angle around its rotating shaft 13, thereby regulate wind speed.

When the utility model is made, process each parts and assembling by above-mentioned requirements, the lower end of main shaft 16 can directly directly be connected with the output shaft of motor equal power device, also can be connected with drive 12, drives main shaft 16 by power set by drive 12 and rotates.9 is that inner housing 8 is fixed in fixture in the housing 4 among the figure, and fixture 9 can be a fixed head, also can be fixed bar.The quantity of fixture 9 can be two, three, four or more a plurality of, and under the prerequisite of guaranteeing inner housing 8 firm stable, for reducing cost, generally the quantity with fixture 9 is decided to be three.Power set can be motor.

During use, first actuating motor and blower fan, motor drives main shaft 16 rotates, and blower fan is sent into a large amount of high temperature drying air-flows in air inlet 19, and air-flow upwards flows through fan blade 11 gaps, is finally discharged by discharging opening 2; Put into by feed pipe 7 and treat broken construction material for example white lime, gypsum etc., material can be in feed pipe 7 enters inner housing 8; After material enters inner housing 8; main shaft 16 drives vertical crushings hammer 5 and rotates to cooperate with inner housing 8 material is broken into powder; powder after smashing falls under gravity on the charging tray 15; charging tray 15 rotates under the drive of main shaft 16; the powder that will fall thereon to around dish out; the powder of being dished out rises to hopper 3 tops by the air-flow drive of 11 of fan blades along vented cavity 17; enter under the effect of wind deflector 1 discharging opening 2 below; the qualified particle of size is sent by discharging opening 2 by air-flow; the underproof particle of size falls under gravity in the hopper 3; enter then and carry out fragmentation again in the inner housing 8; because the angle of wind deflector 1 can be brought the windage of different sizes; therefore; people can pass through the size of the angle Selection powder particle of adjusting wind deflector 1; when people need the powder particle hour; can adjust wind deflector 1; the windage of wind deflector 1 is strengthened; wind can only be sent the particle of satisfactory light weight by discharging opening 2; and the heavier particle of quality can carry out fragmentation again in inner housing 8 is fallen back in the effect of gravity, and so circulation is broken up to reaching the requirement that people are scheduled to.In whole air-supply process, also be air drying process to powder.

Broken oven dry flour mill described in the utility model also can be used for drying wood sawdust, and wood sawdust is the raw material that compacting saws a board.Broken oven dry flour mill described in the utility model also can be applicable to medical aspect.

The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The utility model not technology contents of detailed description is known technology.
