2. impeller head is contained in outside the shot blast room.

3. cleaning chamber is welded into by steel plate, links to each other with shot blast room, divides into the recovery spiral, and cleaning agency is housed.

4. the bullet circulatory system comprises the dark bucket elevator of flat belt, auger conveyor, pneumatic separator, storage bin hopper, the quantitative gate of bullet.

5. roller conveyor, shot blast room and cleaning chamber are passed in chain drive.

It is characterized in that:

1. shot blast room is a hexagon.

2. impeller head is the curve of the blade pattern, there are four, adopt ball blast " intensity-density " comprehensive analysis method, impeller head is arranged in above the shot blast room on the staggered position, upper and lower two limits, staggered position, two limits each one, so that steel plate, particularly sheet metal deflection minimum when cleaning.

In addition, a cover cleaning agency is housed in cleaning chamber, comprises and reclaim auger conveyor, commentaries on classics brush mechanism and blowing mechanism.In shot blast room, on the carrying roller in defeated road special iron protective jacket is housed, and has tongue and groove.

Compared with the prior art the utility model has advantage: (1), be applicable to the removing surface of various section bars, and can be used for the steel-sheet cleaning that thickness is 1.5mm; (2), remove bullet totally, thoroughly; (3), protecting roller carrier shaft is not effectively broken by bullet.

Below in conjunction with accompanying drawing the utility model embodiment is described further.

As shown in Figure 1 and Figure 2, a series of carrying rollers are housed on the roller-way 1, chain drive is driven by motor and reductor, is cleared up workpiece to move on roller-way.Shot blast room 3 and cleaning chamber 10 are equipped with in the middle part of roller-way 1.Shot blast room 3 is welded into hexagon by steel plate, and liner Special Casting Iron backplate is gone to the bottom to establish and reclaimed spiral 2, on hexagonal on the intervening portion of both sides and below respectively arrange an impeller head 13 on the intervening portion of both sides.Cleaning chamber 10 is welded into by steel plate, links to each other with shot blast room, goes to the bottom to establish and reclaims spiral 12, and be equipped with by reclaiming auger conveyor 8 inside, changes the cleaning agency that brush mechanism 9 and blowing mechanism 11 are combined into.

Reclaim auger conveyor as shown in Figure 3, suspension type reduction box 20, pass the chute on the abutment wall, link to each other with the helical axis 17 that has left and right sides flight, two chains 18 from about the end helical axis 17 of ining succession, chain 18 upper ends are walked around a fixed chain wheels and are hung a weight 19, and the lower end links to each other with sprocket wheel on adjusting 15 on handwheel, is fixing the binding clasp 16 of a clamping hand wheel shaft on abutment wall.

Commentaries on classics brush mechanism shown in Figure 4, suspension type reduction box 26, the chute that passes on the abutment wall is connected with commentaries on classics brush 23, two chains 24 are ined succession from two ends, the left and right sides and are changeed brush 23, chain 24 upper ends are walked around a fixed chain wheels and are hung a weight 25, the lower end links to each other with sprocket wheel on adjusting 21 on handwheel, is fixing the binding clasp 22 that clamps hand wheel shaft on abutment wall.

Blowing mechanism shown in Figure 5, comprise that the chute that has on blower fan 33, airduct 31, bellows 32, the bellows 32 on the support Extension support wall links to each other with chain 29, chain 29 upper ends are walked around fast pulley and are connect a weight 30, the lower end links to each other with sprocket wheel on adjusting 27 on handwheel, hand wheel shaft is clamped by the binding clasp 28 that is fixed on the abutment wall, a scavenging conduit also is equipped with in the cleaning chamber bottom, can blow away the floating dust of workpiece bottom.

Fig. 6 represents carrying roller, and inside is roller carrier shaft, and the outside is a Special Casting Iron sheath 34, and has tongue and groove.

The course of work of this descaling machine is such, be conveyed in the shot blast room 3 by roller-way 1 by the cleaning workpiece, bullet from storage bin hopper 5, the quantitative gate 4 of process bullet is defeated by four impeller heads 13 on the shot blast room, bullet is quickened to hit surface of the work, lip-deep oxide skin or rust are disposed, workpiece after the cleaning is sent into cleaning chamber 10 by roller-way, and commentaries on classics in the cleaning chamber 10 brush 23 has been swept the bullet above the workpiece, sends in the recovery auger conveyor 8, through about enter the auger conveyor 12 of shot blast room 3 and cleaning chamber 10 bottoms after carrying, bullet is delivered in the horizontal spiral 14 again, sent into elevator 7 bottoms by it, elevator 7 is sent into bullet in the separator 6, separator 6 with mixtures such as ball rust separately, qualified bullet enters storage bin hopper 5, returns impeller head 13 and uses, and middle bullet returns recirculation in the body of chamber, broken bullet is discharged, and enters ash can.Workpiece goes out cleaning chamber after purging totally by blower fan 33 at last, and by the discharging of tail end roller-way.
