Wanting of the common conveyor screw of rotating shaft revolution ratio of vertical screw conveyor is high, the material adding is under the effect of centnifugal force, and between casing, produce friction force, this friction force stops material to rotate with helicallobe and has overcome the gravity that material declines, thereby has realized the vertical transport of material.This machine operational throughput is little, and delivery head is little, and rotating speed is higher, and energy consumption is large.The good powder and granule shape material of suitable especially flow behavior, is mainly used in improving material, and hoisting depth is generally not more than 8 meters.
As shown in Figure 3, the conveying pipeline 103 of horizontal conveyor screw is generally horizontal arrangement, at the feed end of conveying pipeline 103, hopper 101 is installed, and the discharging opening of hopper 101 bottoms is communicated with conveying pipeline 103 by vertical pipeline 102.Rotating shaft 105 is installed, the outer helicallobe 104 that is fixed with of rotating shaft 105 in conveying pipeline 103.
When material is from hopper enters conveying pipeline, due to the gravity of material and and conveying pipeline tube wall between friction force effect, the material that is deposited in conveying pipeline bottom does not rotate with helicallobe, and only under the helicallobe of rotation promotes, move forward, do motion of translation along the screw rod rotating as non-rotary nut, reach the object of convey materials.This machine is convenient to multiple spot charging and discharging, in course of conveying, can complete mixing, stirring or refrigerating function simultaneously.
Reclaim field at old and useless battery, the container case of plastic material is first broken into small pieces, and then all plastics small pieces enter sorting unit, and the plastic sheet of different colours and material is distinguished.Regenerated plastics sheet falls in above-mentioned hopper after sorting out, and enters conveying pipeline through vertical pipeline.Due to the distinctive physical property of regenerated plastics sheet, and be subject to the restriction of conveying pipeline size, the internal diameter of vertical pipeline is generally less, cause regenerated plastics sheet to be easy to become doming effect even to occur putty at hopper discharging opening place, not only bad for mass transport, and all need to dismantle every day, cleaning, affects production efficiency.
Utility model content
The utility model provides a kind of helix transporting device that prevents feed blocking, utilizes this helix transporting device to carry the materials such as regenerated plastics sheet, can effectively prevent feed blocking or become doming effect.
The technical solution of the utility model is:
A kind of helix transporting device that prevents feed blocking, comprise hopper and the conveying pipeline that is arranged on feed hopper bottom, in described conveying pipeline, rotating shaft is installed, rotating shaft is fixed with helicallobe outward, also comprise the blast pipe for dispelling material, the ventilation inlet of this blast pipe is connected with air compressor, and air outlet extends to the connectivity part of hopper and conveying pipeline.
The utility model utilizes air compressor connectivity part blowing to hopper and conveying pipeline by blast pipe, prevents that material from, at narrow and small connectivity part position bulk deposition, avoiding into doming effect or feed blocking.
As preferably, the air outlet of described blast pipe is towards hopper top.Further improve blowing effect.
And in the utility model, described conveying pipeline is inclined relative to horizontal setting, and feed end is higher than discharge end, and described hopper is arranged on the feed end of conveying pipeline.Feed end is conducive to material higher than the conveying pipeline of discharge end declined rapidly by self gravitation and enters fast conveying pipeline, reduces the accumulation probability of material connectivity part between hopper and conveying pipeline.
As preferably, described conveying pipeline angle of inclination is with respect to the horizontal plane 10～60 degree.As further preferred, described conveying pipeline angle of inclination is with respect to the horizontal plane 20～40 degree.Suitable angle of inclination had both been conducive to increase material self gravitation, also reduced the lifting difficulty of conveying pipeline feed end.
As preferably, the bottom of described hopper is with discharging opening, and this discharging opening docks with the charging port of conveying pipeline, and the end of described rotating shaft and helicallobe is stretched in hopper.The utility model has saved the vertical pipeline between hopper discharging opening and conveying pipeline in prior art, and conveying pipeline is directly docked with hopper, and rotating shaft and helicallobe are stretched in hopper, so the material in hopper can be pushed out by helicallobe in time, prevents from stopping up.
Compared with prior art, the beneficial effects of the utility model are:
(1) helix transporting device band of the present utility model is useful on the blast pipe that dispels material, utilize air compressor connectivity part blowing to hopper and conveying pipeline by blast pipe, prevent that material from, at narrow and small connectivity part position bulk deposition, avoiding into doming effect or feed blocking; No longer need dismounting cleaning every day, time saving and energy saving, save a large amount of human costs, also reduce the maintenance time of equipment;
(2) the utility model has saved the vertical pipeline between hopper discharging opening and conveying pipeline in prior art, and conveying pipeline is directly docked with hopper, and in rotating shaft and helicallobe material bin, so the material in hopper can be pushed out by helicallobe in time, prevents from stopping up;
