Detailed description of the invention
Fig. 1 is the decomposition diagram of continuous discharging device of the present invention.
Fig. 2 is the assembling schematic diagram of continuous discharging device of the present invention.
Specific embodiment
Referring to Fig. 1 and Fig. 2, continuous discharging device shown in figure, including a discharge barrel 100 and positioned at discharge barrel 100
It discharging screw auger 200 in barrel chamber 110 and is mounted on discharge barrel 100 for drive the discharging rotation of screw auger 200
Driving device 300, driving device 300 can be a decelerating motor or motor acceleration and deceleration case or be other driving mechanisms.
Discharge barrel 100 close to 300 one end of driving device be provided with one connect with the discharge end of vacuum dryer into
Material mouth 120 is provided with a discharge port 130 close to the position of discharging 200 end 210 of screw auger in discharge barrel 100.Discharge barrel
100 barrel chamber 110 is in cone, and the internal diameter positioned at 120 side of feed inlet is big, and the internal diameter positioned at 130 side of discharge port is small；Discharging
The outer diameter that screw auger 200 is located at 120 side of feed inlet is big, and the outer diameter positioned at 130 side of discharge port is small, and discharge screw auger
200 screw pitch is gradually reduced from feed inlet 120 to discharge port 130.The flow area of discharge port 130 is less than the logical of feed inlet 120
Flow area.
Vacuum is also not limited to certainly for environment under low pressure such as vacuum in the barrel chamber 110 of discharge barrel 100, outside discharge port 130
For the atmospheric environment of such as one atmospheric pressure of hyperbaric environment, it is also not limited to the atmospheric environment of an atmospheric pressure certainly, as long as going out
The environmental pressure that environmental pressure outside material mouth 130 is greater than in the barrel chamber 110 of discharge barrel 100 belongs to protection scope of the present invention.
The temperature of material, can be provided on the barrel of discharge barrel 100 in barrel chamber 110 in order to keep discharge barrel 100
Keep the temperature jacketed or insulating layer (not shown), naturally it is also possible to be not provided with keeping the temperature jacketed or insulating layer, as long as in discharge barrel 100
Material keep softness be not hardened just.
A feature of the present invention is on discharge port 130 by being equipped with a cover board 400, the inner surface 410 of cover board 400
There is a distance between discharging 200 end 210 of screw auger, this section distance forms a material accumulation chamber, material accumulation chamber
Interior no discharging screw auger.The method for forming this material accumulation chamber in this embodiment is in discharge port
One discharge hole joint 500 is installed, the feed side 510 of discharge hole joint 500 and the discharge port 130 of discharge barrel 100 connect on 130
It connects.Discharge hole joint 500 can be made of one formula with discharge barrel 100, can also it is separately manufactured then using welding or riveting or
Thread connecting mode is fixed on discharge port.
Cover board 400 is mounted on the exit side 520 of discharge hole joint 500 by frictional force；The feed side of discharge hole joint 500
It is above-mentioned material accumulation chamber 530 between 510 and exit side 520.Between cover board 400 and the exit side 520 of discharge hole joint 500
Frictional force be to be equipped with one on the excircle for rely on cover board 400 to generate the O-ring seal of frictional force and sealing function
420 come what is realized, and O-ring seal 420, which generates frictional force, is mounted on cover board 400 on the exit side 520 of discharge hole joint 500.
Certain O-ring seal 420 also may be mounted on 520 inner periphery of exit side of discharge hole joint 500.
Another feature of the present invention is that cover board 400 has following three kinds of states:
The first state is the cover board 400 before the material in material accumulation chamber 530 does not form isolation environment under low pressure effect
By pressure difference caused by its frictional force and environment under low pressure between the exit side 520 of discharge hole joint 500 and hyperbaric environment
The exit side 520 of discharge hole joint 500 is sealed up.
After second of state is that the material accumulated in material accumulation chamber 530 forms isolation environment under low pressure effect, cover board
400 discharge the exit side 520 of discharge hole joint 500 by its frictional force between the exit side 520 of discharge hole joint 500
Mouth seals up.
The third state is: the sum of 400 own wt of material pressure and cover board only in material accumulation chamber 530 is greater than
After the sum of pressure of frictional force and hyperbaric environment between cover board 400 and the exit side 520 of discharge hole joint 500, cover board 400 is certainly
It moves and falls down the progress continuous discharge of exit side 520 for opening discharge hole joint 500, during continuous discharge, in material accumulation chamber 530
Always accumulation has certain thickness and forms the material bed of isolation environment under low pressure effect.
In use process of the present invention, the dried material in the barrel chamber 110 of discharge barrel 100 is entered by feed inlet 120 due to interior
Heat is also more soft, has good plasticity, and material passes through the spiral that discharges during from feed inlet 120 to discharge port 130
The extruding of auger 200 is gradually filled with the barrel chamber 110 of entire discharge barrel 100, due to not discharging spiral in material accumulation chamber 530
The packing auger blade of auger 200 conveys the material to come by discharging screw auger 200 and gradually accumulates in material accumulation chamber 530, directly
Cover board is greater than to the sum of 400 own wt of material extruding force and cover board in material accumulation chamber 530 to discharging screw auger 200
After the sum of pressure of frictional force and hyperbaric environment between 400 and the exit side 520 of discharge hole joint 500, cover board 400 falls automatically
The lower exit side 520 for opening discharge hole joint 500 carries out continuous discharge, through-flow due to discharge port 130 during continuous discharge
Flow area of the area less than feed inlet 120, the packing auger blade of screw auger 200 in addition material accumulation chamber 530 does not discharge, because
Accumulation always has certain thickness and forms the material bed of isolation environment under low pressure effect in this material accumulation chamber 530, guarantees production
It goes on smoothly.In order to be conducive to the production and processing in later period, third feature of the present invention is bottom and the lid in material accumulation chamber 530
It is provided with a porous plate 600 between the inner surface 410 of plate 400, when discharging, the material of 530 bottom of material accumulation chamber passes through porous
Hole on plate 600 forms fine strip shape continuous discharge.Porous plate 600 can be pressed in material accumulation chamber 530 by a pressure ring 610
On bottom, can also such as welding manner it be fixed on the bottom of material accumulation chamber 530 otherwise.
