positive beneficial effect:
1, this device has advanced design concept, and this design is no longer confined to change merely the thinking that warehouse geometry improves Flow of Goods and Materials state and then solves feed blocking in warehouse.But allow static bulkhead move up, and coordinate inner block clearing spiral, realize the function of the anti-blocking block clearing of initiative broken arch, searched out one simply and the anti-blocking new way of actv. warehouse breakthroughly.
2, this device is arranged on the easily stifled section (ratio of this section of obstruction accounts for whole storehouse and stops up the more than 90% of number of times) in cone storehouse, the 100% feed blocking problem that has solved this section not only, but also actv. has improved the flow regime of whole warehouse materials inside, and then the material wall built-up problem at inner other positions of alleviation warehouse.
3, this device is formed shaftless spiral and is forced conveying system by rotate relative with fixing spiral fashion scraper of roll-over body, solves chute blockage problem at all, adopts variable-pitch screw propulsion blade, reduces rotary-cut stressed, increases anti-blocking height.
4, this device is arranged on easily stifled section of run coal bin end opening, is arranged on block clearing effect herein remarkable.
5, can realize the long-range conversion of controlling on the spot, manually control action, also can realize regularly start and stop.
6, can change the flow regime in warehouse, make the flow regime of material in storehouse flow and again revert to bulk flow by center.
7, adopt the design of labyrinth type side seal, prevent flour dust overflow, improve work condition environment.
8, this apparatus structure is simple, reliable, easy for installation, and maintenance is little, is particularly suitable for the technological change of old Power Plant Bunker.
This installs this and passes through mechanical drive, allow standing warehouse in traditional sense rotate, by rotation warehouse and the fixing relative shaftless helical conveyer system that rotates to form of spiral fashion scraper, the basic chute blockage problem that solves, simple in structure, reliable, easy for installation, maintenance is little, is particularly suitable for the technological change of old Power Plant Bunker.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present utility model:
In figure, be: upper fixed bin 1, link span 2, upper sealing 3, roll-over 4, without axial spiral type scraper 5, driven gear 6, driving gear 7, stay bearing plate 8, surface bearing 9, reductor 10, lower seal 11, lower fixed bin 12, putty detecting sensor 13.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, roll-over formula prevention spiral block apparatus, device is arranged on easily stifled section of run coal bin end opening, comprises fixed bin 1, lower fixed bin 12, roll-over 4, without axial spiral type scraper 5 and link span 2 and mechanical transmission mechanism; Described upper fixed bin 1 is connected with original feed bin, and lower fixed bin 12 is connected with original tremie pipe; Upper fixed bin 1 is linked to be an integral body with lower fixed bin 12 by link span 2;
