Abstract
The utility model discloses a powder product circularly feeding device, which is characterized in that the inside of a feeding box body is parallel provided with a discharging and a feeding back helical shafts; one end of the feeding box body is connected with two independent feeding and feeding back helical barrels, and the feeding box body is communicated with a discharging box body; the discharging and the feeding back spiral shafts are respectively sheathed with the feeding and the feeding back barrels, the discharging and the feeding back spiral shafts also extend into the discharging box body, and one end of the discharging box body is provided with a discharging controlling valve. The discharging and the feeding back shafts and the discharging and the feeding back barrels are driven to rotate by a motor, so the material discharging of an entire machine can have certain uniform flow quantity, and the remaining powder material in the discharging box can enter the feeding box circularly; the utility model has the advantages of easy use and simple structure.
Description
The utility model relates to the equipment that the powder feed is used, and utilizes helical rotation to send powder specifically, and has the feeder of circulation conveying function.
The feeding coal of the various powders in the storehouse, storehouse is equipped with gate by the storehouse, storehouse at present, opens the sluices when feed and is equipped with feeder simultaneously, and such technology is used the uniform and stable feed that does not have on the feed, can not accomplish stably feeding, and it is also very inconvenient to put the dress powder simultaneously.
The purpose of this utility model provides a kind of feeding coal of powder can adjust the even can feed of blowing amount arbitrarily, and can control, the remaining powder in powder arrival exit can return automatically and reach the charging casing, plays the circulating screw feeder of circulation even feeding effect.
For finishing the technical scheme that purpose adopted of foregoing invention: complete machine is established motor and is connected change speed gear box by belt, and the change speed gear box rotating shaft connects the discharging screw shaft in the charging casing.Parallel two discharging screw shafts and feed back screw shaft are set in the charging casing, one end of charging casing connects two independently charging pipe tube and feed back pipe tubes by flange respectively, these two independently the other end of cylindrical shell be communicated with the discharging casing, above-mentioned discharging screw shaft and feed back screw shaft are inserted in charging pipe tube and feed back pipe tube respectively, enter the discharging casing simultaneously, discharging is connected with two gears by two transmission shaft bearings with the feed back screw shaft, two gears are meshing with each other, with counter-rotation, an end of above-mentioned discharging casing sets out the material control cock.
The utility model embodiment is described in detail to closing accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is a discharging casing cutaway view.
According to shown in Figure 1, complete machine has motor 11 to be cooperated with change speed gear box 14 by speed pulley 13 by belt 12 to carry out speed change, the discharging screw shaft 7 that change speed gear box rotating shaft 10 connects in the charging casing 9, discharging screw shaft 7 and feed back screw shaft 15 be arranged in parallel in charging casing 9, the other end of charging casing 9 connects two independently charging pipe tube 6 and feed back pipe tubes 16 by flange 8 respectively, the spiral tube 6 of above-mentioned two separate feeds and feed back and 16 end are interconnected by flange 5 and discharging casing 4, discharging screw shaft 7 and feed back screw shaft 15 are inserted in charging cylinder 6 and feed back pipe tube 16 respectively, and enter discharging casing 4, by two pass bearing seats 3 respectively with gear housing 1 in gear 2 be connected with gear 19, gear 2 is meshing with each other with gear 19, with counter-rotation, therefore discharging screw shaft 7 and feed back screw shaft 15 are also with just, the conter clockwise different directions rotates, to reach the circulation of powder.One end of above-mentioned discharging casing 4 sets out material control cock 18 as shown in Figure 2, what of load can adjusting control valve 18 handwheel 17, make control cock 18 reach different required apertures and reached dosing, and the residue powder in the discharging casing 4, again push charging casing 9 to by feed back screw shaft 15, reach the on-cycle purpose.The utility model is simple in structure, and is easy to use.
