Description

Three in conjunction with step flour scrapper conveyor

Technical field

A kind of flour scrapper conveyor is the utility model is related to, especially one kind three is in conjunction with step flour scrapper conveyor.

Background technology

Horizontal feed is carried out to semi-finished product or final flour in fluor producing process and mainly uses screw auger and scraper plate Machine, and in wheat flour milling workshop section, with the raising being continuously increased with technique processing technology of wall scroll production line output, high side multideck screen It is continuously increased with the usage quantity of wheat flour purifier, same floor mileage platform high side multideck screen screens out the material for the different fineness grade come, It is required for delivering into wheat flour purifier again after according to technological requirement collecting and screen or mills again, is nearly all to use three spiral shells now Auger is revolved to undertake the effect of total powder auger.But due to being now to ask material fed distance increasingly longer, up to tens of meters Moment of torsion in the operating of packing auger blade axis is very big, and especially problem is more obvious on startup, so the decelerating motor selected is also more next Bigger, the problem of power consumption is big, becomes increasingly conspicuous；Moreover, to avoid long distance delivery screw-conveyer-shaft from moving about grazing casing, blade and casing Gap have to be put into 5-10mm, another serious problems for so causing screw auger are exactly along auger whole length direction Bottom flour residual quantity is very big, not only causes the conveyance loss of material, and cleaning is time-consuming and laborious, and as cleared up not in time, holds Easily cause the cross contamination between different material, easily go mouldy with it is infested, directly affects the food security of flour, this Be flour mill the most headache the problem of.

In scrapper conveyor work of the prior art, machine head chain wheel axis and tail sprocket shaft rotate and drive conveyor chain to advance, Conveyor chain turns at machine head chain wheel axis and tail sprocket shaft respectively, realizes continuous cycle operation, scraper plate is in conveyor chain Material is delivered to discharge port discharge from feed inlet under drive.Tail sprocket shaft can be affected by adjusting hanging screw and hanging tight nut Move in the horizontal direction, so as to change the centre-to-centre spacing between machine head chain wheel axis and tail sprocket shaft, conveyor chain is kept appropriate Tension force.Scrapper conveyor is since the popularization of scraper plate high molecular material is plus being chain drive, and conveying capacity is strong, and scraper plate is in chain-driving Directly contacted with bottom of shell down, gapless, bottom flour residual quantity very little, therefore the advantage in flour long distance delivery is got over Come more obvious.

The country is currently without three integral type flour scrapper conveyors, although some producers are replaced with 3 independent scrapper conveyors Generation universal three total powder screw augers at present, but due to 3 scrapper conveyors by every equipment transmission device, tensioning apparatus Limitation, plus that must reserve certain operation and safe distance between every equipment, the position that plane occupies is very big, this for All it is extremely difficult arrangement for the technology arrangement of most of newly-built and existing transformation production lines, because, 3 scrapper conveyors If inlet and outlet position cannot concentrate, the intersection of story height side's tens of pipelines of plansifter screenings is directly affected, can not be ensured The angle of every pipeline meets flour angle of repose requirement, and material will block in expects pipe, as a same reason, into scrapper conveyor Material can not be also assigned to flour angle of repose in the wheat flour purifier of next floor.Thus, there is an urgent need to have a kind of volume tight Gather, three integral type scrapper conveyors rational in infrastructure meet that flour collects, conveys and the technological requirement of discharging.

The content of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided one kind three is in conjunction with step flour scraper plate Machine, to meet to substitute three screw auger of existing total powder in the case of story height is not increased in wheat flour milling workshop section, meets high Flour collects, conveys and the technological requirement of discharging under square plansifter, reduces flour residual, reduces energy consumption.

According to technical solution provided by the utility model, described three in conjunction with step flour scrapper conveyor, including be set up in parallel One scrapper conveyor, the second scrapper conveyor and the 3rd scrapper conveyor, it is characterized in that：First scrapper conveyor, the second scrapper conveyor and the 3rd scraper plate Machine includes head, middle transportation section and tail, in the head of first scrapper conveyor, the second scrapper conveyor and the 3rd scrapper conveyor First drive sprocket, the second drive sprocket and the 3rd drive sprocket are installed respectively equipped with drive chain wheel shaft, on drive chain wheel shaft, driven Movable sprocket axis connection decelerating motor；It is respectively equipped with the tail of first scrapper conveyor, the second scrapper conveyor and the 3rd scrapper conveyor First tail sprocket shaft, the second tail sprocket shaft and the 3rd tail sprocket shaft, install the first tail chain on the first tail sprocket shaft Take turns, the second tail sprocket wheel is installed on the second tail sprocket shaft, the 3rd tail sprocket wheel is installed on the 3rd tail sprocket shaft；Described first Drive sprocket and the first tail sprocket wheel, the second drive sprocket and the second tail sprocket wheel and the 3rd drive sprocket and the 3rd tail Conveyor chain is installed around between sprocket wheel respectively, scraper plate is installed on conveyor chain；The first tail sprocket shaft and the 3rd tail sprocket wheel Axis connects afterbody strainer respectively, and the both ends of the second tail sprocket shaft connect side strainer respectively.
