The specific embodiment
Embodiment: referring to Fig. 1-Fig. 2, a kind of feeding back device in figure, comprise receiving hopper, feed pipe, described receiving hopper is connected to an end of feed pipe, establish a pestle bar in feed pipe, one end of described pestle bar is connected with rope class connector, and the other end of rope class connector stretches out outside feed pipe and is connected with the hopper outermost end.Described rope class connector is loop chain, and the length of loop chain is exactly the length range that the pestle bar can be movable in feed pipe.The length of described pestle bar and the length of feed pipe coupling can just can run through the penetrating of whole feed pipe assurance feed pipe by the pestle bar like this when activity.
Embodiment bis-: referring to Fig. 1-Fig. 4, a kind of roller drying machine with feeding back device in figure, comprise barrel, the capping of cylinder end, feeding device, described barrel comprises N level cylinder, be followed successively by from inside to outside first order cylinder, second level cylinder ... N level cylinder, described feeding device through capping to feeding in first order cylinder, it is characterized in that: the discharge end of described second level cylinder is that the feed end place of third level cylinder along the circumferential direction is provided with several feeding back devices, this feeding back device comprises receiving hopper, feed pipe, described receiving hopper is connected to an end of feed pipe, establish a pestle bar in feed pipe, one end of described pestle bar is connected with rope class connector, the other end of rope class connector stretches out outside feed pipe and is connected with the hopper outermost end, the outermost end of hopper is fixedly connected on the inwall of feed end of third level cylinder, described feed pipe inwardly passes first order cylinder to first order cylinder inside, the opening direction of hopper is consistent with the direction of rotation of barrel.Described rope class connector is loop chain.The length of loop chain is exactly the length range that the pestle bar can be movable in feed pipe.The length of described pestle bar and the length of feed pipe coupling.Can just can when activity, run through the penetrating of whole feed pipe assurance feed pipe by the pestle bar like this.The axial direction of described feed pipe with respect to barrel radially between clockwise drift angle α is arranged.Like this barrel the rotation process in connect material the head in material will in first order cylinder, slide early.The described 5 °≤α in drift angle≤15 °.Also be provided with broken shaft in described first order cylinder, can be broken up fragmentation to the material in first order cylinder, the inwall of described every grade of cylinder all is provided with around the scraping wings of cylinder axis spiral surrounding and the lifting blade arranged along the cylinder generatrix direction.Scraping wings and lifting blade are parts common in the dryer of this area, its concrete structure and effect can referenced patent number: 200620031704.6, title: the Chinese utility model patent of single-stage drying drum and multilevel drying cylinder and novel dryer for high humidity material thereof, again do not do too much detailed description.
Certainly this capping with the roller drying machine of feeding back device is survived and should be included the structure of sending hot blast and hydrofuge gas, and the seal member between capping and barrel, these are all structures general in prior art, are not the inventive point places of patent, therefore do not list one by one at this.
Be somebody's turn to do the course of work with the roller drying machine of feeding back device:
The wet stock of crossing that water content is high is sent in the first order cylinder in barrel by the spiral propeller of feeding device, barrel is in the process of rotation, because the effect material of inner scraping wings and lifting blade is shed on one side in cylinder, rolling forward on one side, the axle that is broken in the process of shedding carries out fragmentation to be broken up, and is convenient to dry, after the end of material movement first order cylinder, automatically fall in the cylinder of the second level, contrary due to the direction of the scraping wings in the cylinder of the second level and first order cylinder, material moves to another direction while drying with the rotation of cylinder, until move to the feed end place that the discharge end of second level cylinder is third level cylinder, partial material can enter in the receiving hopper of device, rotation along with cylinder, material in receiving hopper is also along with rise, the certain altitude risen when receiving hopper is, effect due to gravity, material slides in from receiving hopper to feed pipe, continuation is along with the rotation of cylinder, before and after this receiving hopper rotates to highest point, the pestle bar falls under the effect of gravity, material in the moving feed pipe of pestle, make its whereabouts, avoid stopping up feed pipe, drum rotating to be continued is worked as this receiving hopper and is rotated to lowest part, the pestle bar is because Action of Gravity Field falls, go round and begin again, start next circle motion, the same work like this of other feeding back devices.
Loop chain in above-mentioned two embodiment also can replace with chain or rope.
Common parts in the dryer of this areas such as scraping wings and lifting blade can be arranged in the barrel in above-described embodiment, specific constructive form can be with reference to Chinese utility model ZL200620031704.6, title: the Chinese utility model patent of single-stage drying drum and multilevel drying cylinder and novel dryer for high humidity material thereof.
Breaing up axle and breaing up the version of revolving rake in above-described embodiment can be invented ZL201110163259.4 with reference to China, title: the concrete technical scheme that the background technology in Semi-shaft rotary harrow scattering device and embodiment relate to.
