Specific embodiment

As described below is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit Decorations are also considered as the protection scope of the utility model.Term in the specification and claims of the utility model and the attached drawing " first ", " second " etc. are not use to describe a particular order for distinguishing different objects.In addition, term " includes " and " tool Have " and their any deformations, it is intended that it covers and non-exclusive includes.Such as contain the mistake of a series of steps or units Journey, method, system, product or equipment are not limited to listed step or unit, but optionally further comprising do not list The step of or unit, or optionally further comprising other step or units intrinsic for these process, methods, product or equipment.

Referenced herein " embodiment " is it is meant that a particular feature, structure, or characteristic described can wrap in conjunction with the embodiments It is contained at least one embodiment of the utility model., which there is the phrase, in each position in the description to be each meant Identical embodiment, nor the independent or alternative embodiment with other embodiments mutual exclusion.Those skilled in the art are explicit Ground and implicitly understand, embodiment described herein can be combined with other embodiments.

Referring to Fig. 1, the utility model provides a kind of floating grain de- material system 10 of intelligence, the intelligence floats grain de- material system 10 Including drop forming device 100, cooling equipment 200 and stripper 300.The drop forming device 100 is for providing liquid Drop.It is understood that the drop forming device 100, which can be any one, can eject the device of drop.It is described cold But equipment 200 includes cooling zone 210, driving wheel 220 and driven wheel 230, and the cooling 210 is with around 220 He of driving wheel The driven wheel 230 rotates, and the cooling zone 210 is used to drop being cooled into coronal fertiliser granulates.It is understood that cold But band 210 can be the belt of PVC, PU, PE or rubber material, preferably steel band, and steel band absorbs the speed of drop heat Comparatively fast, to be quickly cooled down drop.The cooling zone 210 includes feed end 211 and discharge end 212, and the feed end 211 is for connecing By the drop, the discharge end 212 refers to the part cooling zone 210 being transmitted at the driven wheel 230 and is described coronal The position of fertiliser granulates discharging.The drop ejected from drop forming device 100 falls in feed end 211, it is preferred that drop with Positive and negative 45 degree of vertical direction fall on feed end 211, and fertiliser granulates hardness after cooling in this way is larger, and drop falls in feed end After 211, under the action of driving wheel and driven wheel, cooling zone is moved to discharge end 212, drop cooled shape in moving process At coronal fertiliser granulates.The stripper 300 is arranged close to the discharge end 212, for by the coronal fertiliser granulates from It is split away off in the cooling zone 210.Since fertilizer drop itself has certain viscosity, when drop is fallen in cooling zone, liquid Body is volatilized, and finally formed coronal fertiliser granulates can be sticky in cooling zone, when coronal fertiliser granulates are moved to discharge end simultaneously It cannot fall off from cooling zone well.Stripper 300 in the utility model can be by coronal fertiliser granulates from described cold But it is split away off on band 210, to accelerate industrialization production.

Referring to Fig. 2, in a further embodiment, the stripper 300 includes the scraper plate 310 that falls off, described to fall off The discharge end 212 of the cooling zone 210 is arranged in scraper plate 310, and the scraper plate 310 that falls off includes scraper part 311, the scraper The distance between portion 311 and the discharge end 212 are 0-1 millimeters.It is understood that when scraper part 311 and discharge end 212 it Between distance when being 0 millimeter, that is, scraper part 311 and discharge end 212 overlap, but are not fixed, but activity is taken Connect, the cooling zone at discharge end remains to rotate around driven wheel, scraper part 311 at this time because and cooling zone in close proximity to scraping Knife portion the active force of coronal fertiliser granulates is transmitted with cooling zone it is contrary, so can be effectively by coronal fertiliser granulates It falls off from cooling zone.When the distance between scraper part 311 and discharge end 212 are greater than 0 millimeter, scraper part 311 can be by grain The biggish coronal fertiliser granulates of diameter fall off.Adjustment scraper part 311 and discharging can be adapted to according to the fertiliser granulates of different-grain diameter size The distance between end 212.Preferred distance is 0.1-1 millimeters.

In further embodiment, the scraper plate 310 that falls off further includes support portion (not shown), the support portion with it is described Driven wheel 230 is flexibly connected, and the support portion is connect with the scraper part 311, is used to support the scraper part 311.Driven wheel 230 be ceaselessly to rotate in the operating condition, can not both driven wheel be hindered to revolve using being flexibly connected with driven wheel support portion It changes a job work, and can achieve the purpose of support scraper part 311.It is understood that support portion can also be arranged on the ground, with Support scraper part.It is understood that from the fertiliser granulates that scraper part strikes off out by support portion charging material-gathering device.

In a further embodiment, the driven wheel 230 includes multiple sub- driven wheels 231, and multiple sub- driven wheels 231 are in Periodic arrangement is below discharge end 212.Multiple sub- driven wheels 231 are used at discharge end, it is adjacent from cold between driven wheel But band has opposite effect, from increasing the tension of cooling zone, and then is conducive to improve discharge end cooling belt surface fertiliser granulates Falling-off effect.

Referring to Fig. 3, in a further embodiment, the tangent line A of the scraper part 311 and 212 intersection 213 of discharge end Angle α with scraper part 311 is 0-45 °.Scraper part 311 and the tangent line A of 212 intersection 213 of discharge end refer to driven wheel in phase The cooling zone of 213 tangent line A at friendship, discharge end 212 are rotated around driven wheel, and cooling zone is moved to direction of motion when intersection The exactly direction tangent line A of intersection 213.That is force direction and intersection of the scraper part 311 to coronal fertiliser granulates The angle of the direction of motion at place is α, can achieve the fertiliser granulates of effectively abjection cooling zone in this way.Preferred angle α is 0- 30°.It is furthermore preferred that scraper part 311 is to the force direction of coronal fertiliser granulates and the movement of intersection when angle α is 0 ° Direction is exactly the opposite, and active force is maximum, and scraping effect is more preferable.
