The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
More preferably, aforesaid rotation broken arch machine, is uniform-distribution with three screw stereo broken arch cones in wherein said big gear wheel.
More preferably, aforesaid rotation broken arch machine, wherein said screw stereo broken arch cone adopts 40Cr inblock cast to form.
More preferably, aforesaid rotation broken arch machine, the distance between wherein said screw stereo broken arch cone and this rotation centrum inwall is 10 ± 5mm.
By technique scheme, the present invention at least has following advantages and beneficial effect:
1, rotation broken arch facility have advanced design concept, and screw stereo broken arch cone is fixed in big gear wheel, motor reducer Drive pinion, and miniature gears engages with big gear wheel, and big gear wheel rotarily drives screw stereo broken arch cone work broken arch, and power of motor is little, economize on electricity.
2, rotate broken arch machine machine and be arranged on the easily stifled section (on coal gate mouth, 1.5m-3m is interior) of boring storehouse, broken arch effect is remarkable.
3, rotation broken arch machine adopts screw stereo broken arch coning incision technology, and reduction broken arch cone is cut stressed, increases anti-blocking height.
4, the motor reducer in the present invention is connected with the external electrical control cubicles at the other correct position of equipment by cable, can realizes the long-range conversion of controlling on the spot, manually control action, also can realize timing start and stop.
5, can change the flow regime in warehouse, make the flow regime of material in storehouse flow and again revert to bulk flow by center.
6, adopt integrated shaft to labyrinth, slot type Seal Design, without spilling Lou coal phenomenon, prevents flour dust overflow, improves work condition environment.
7, this machine is simple in structure, reliable, easy for installation, and maintenance is little, is particularly suitable for the technological change of old power plant feed bin.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification sheets, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
