Abstract
The utility model discloses a kind of extruder blanking hopper, hopper lower half portion uses double-layer structure with dissection, is connected between internal layer and outer layer using flight, and hopper is fixed on extruder by hopper pedestal.The extruder of the utility model blanking hopper, it is simple and practical in structure, in process of production can effectively extruder feed port generate in hot gas, moisture is effectively discharged by the helical duct between the ectonexine of hopper lower half portion, dust will not be generated again simultaneously, effectively avoid in material blanking process leads to arch formation due to moisture, the working efficiency for improving double screw extruder granulation, alleviates the workload of worker.
Description
Technical field:
The utility model relates to a kind of extruder blanking hoppers.
Background technique:
In conventional double screw extruder hopper field, the hopper generallyd use is open inverted conical shape hopper knot
Structure.When raw material feed intake from hopper upper cover, since hopper sheet is as sealed, the heat returned out in by extruder barrel body
Gas influences, and the hot gas of extruder feed port generation can not be discharged in conventional hopper, causes headwall and material on the inside of hopper to make moist, material
In powder can be adsorbed on headwall, the time, which has been grown, causes hopper to build bridge.When bridge formation accident occurs, direct labor will be shut down
Disassembly hopper is cleared up, and production efficiency is seriously affected, and increases worker's amount of labour.
Utility model content:
The utility model is to provide a kind of extruder blanking hopper to solve the above-mentioned problems of the prior art.
Technical solution used by the utility model has: a kind of extruder blanking hopper, including hopper, internal layer, spiral
Piece, outer layer and hopper pedestal, the internal layer are fixed on hopper lower end, and outer layer is fixed on hopper pedestal, between outer layer and internal layer
It is linked together by flight, and forms effective spiral exhaust.
Further, the outer 5-15mm of hopper pedestal is stretched out in the bottom end of the internal layer.
Further, the top of the hopper is equipped with hopper cover.
The utility model has the following beneficial effects: the utility model double screw extruder powder blanking hopper, structure letter
It is single practical.Hot gas, the moisture of extruder feed port generation effectively can be passed through hopper lower half in process of production
The helical duct between sandwich of layers divided is effectively discharged, can be by hot gas since entire channel is that left-hand thread rotation is upward
The process of moisture discharge is without spraying powder.It fundamentally solves to build bridge caused by material affected by moisture in hopper.
The working efficiency for effectively raising the granulation of double screw extruder powder, alleviates the workload of worker.
Detailed description of the invention:
Fig. 1 and Fig. 2 is the utility model structure chart.
1, feeding port, 2, hopper upper cover, 3, hopper bucket body, 4, internal layer, 5, flight, 6, outer layer, 7, hopper pedestal, 8, row
Outlet.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
As depicted in figs. 1 and 2, a kind of extruder of the utility model blanking hopper, including hopper 3, internal layer 4, flight
5, outer layer 6 and hopper pedestal 7, the hopper lower half portion are sandwich double-layer structure, and outer layer 6 is fixed on 7 pedestal of hopper, outside
It is linked together between layer 6 and internal layer 4 by flight 5, and forms effective spiral exhaust.
Hopper upper cover 2 is equipped on the top of hopper bucket body 3.The outer 5-15mm of hopper pedestal 7 is stretched out in the bottom end of internal layer 4.
Material from the feeding port 1 of hopper be sent into hopper in when, hopper upper cover 2 and hopper bucket body 3 are sealed, when material into
It after in material bin, enters in the spout of extruder by internal layer 4, since extruder barrel is high-temperature heating state, enters
The hot gas generated after melting after cylinder has part hot gas can be returned in material bin by the extruding of barrel inner screw；Work as extruder barrel
When intracorporal hot gas returns material bin, since the height of hopper internal layer 4 stretches out hopper pedestal 7, the blocking of inner layer wall, hot gas are received
Know from experience and be discharged along the channel between ectonexine, due to the blocking by flight 5, avoids powder and sprayed from helical duct.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The protection scope of the utility model.
