As depicted in figs. 1 and 2, a kind of embodiment of feed bin of the invention.The feed bin of the present embodiment can be used for storing in bulk
Raw material is particularly suitable for the storage of glass raw material and feed in glass production.
Referring to Fig. 1, the feed bin of the present embodiment includes cylinder 1, material mouth plug 2 and driving mechanism 3.Wherein, it is formed inside cylinder 1
One cavity 10, the cavity 10 is for containing raw material.Cavity 10 have a discharging portion 101, the open at its lower end of discharging portion 101, for
The raw material outflow contained in cavity 10, realizes blanking.Also, the internal diameter of discharging portion 101 is gradually reduced from top to bottom, i.e. discharging portion
101 be in back taper, and the raw material be conducive in cavity 10 concentrates whereabouts to discharging portion 101.Cavity 10 also has a main storehouse portion 102,
Main storehouse portion 102 is located at the top of discharging portion 101, and the lower end in main storehouse portion 102 is connected with the upper end of discharging portion 101, by main storehouse
Portion 102 and discharging portion 101 collectively form the cavity 10.Preferably, the axis phase of the axis with discharging portion 101 in main storehouse portion 102
It is overlapped, is conducive to raw material in the main storehouse portion 102 of cavity 10 to 101 even drop down of discharging portion.The shape in main storehouse portion 102 not office
Limit, preferably can be set to cylinder, and the internal diameter in cylindrical main storehouse portion 102 preferably (goes out with the maximum inner diameter of discharging portion 101
The internal diameter of 101 upper end end face of material portion) it is equal.A feed inlet 11 is equipped on cylinder 1, which is connected with main storehouse portion 102
It is logical, from feed inlet 11 can into cavity 10 charging feedstock.
Material mouth plug 2 is set in cavity 10, and material mouth plug 2 has an adjustment portion 21, and outer profile and the cavity 10 of adjustment portion 21 go out
The Internal periphery in material portion 101 matches, i.e., adjustment portion 2 is also in the back taper that outer diameter is gradually reduced from top to bottom.Adjustment portion 21 is located at
Discharging gap H is formed in discharging portion 101, and between adjustment portion 21 and discharging portion 101, i.e. the outer profile size of adjustment portion 21 is opposite
The Internal periphery size of discharging portion 101 is smaller, therefore when adjustment portion 21 is placed in discharging portion 101, adjustment portion 21 and discharging portion 101 it
Between there is interval, form the discharging gap H.The raw material that discharging portion 101 is fallen into cavity 10 can be through discharging gap H from discharging portion
101 open lower end outflows, therefore the discharging gap H is the discharge port for constituting the feed bin of the present embodiment, the size for the gap H that discharges
It determines the size of discharge port, also determines the size for the tapping flowrate that raw material is flowed out from feed bin.
Driving mechanism 3 is connected with material mouth plug 2, also, driving mechanism 3 drives material mouth plug 2 to move up and down in cavity 10.
It drives material mouth plug 2 to move up and down in cavity 10 by driving mechanism 3,2 adjustment portion 21 of material mouth plug can be changed and discharge with cavity 10
The relative position in portion 101 adjusts the spacing distance between adjustment portion 21 and discharging portion 101, the i.e. size of adjustment discharging gap H,
To realize the adjusting control of raw material tapping flowrate size, specifically: when material mouth plug 2 moves downward, discharging gap can be reduced
H, to reduce raw material tapping flowrate；When material mouth plug 2 moves upwards, discharging gap H can be expanded, to increase raw material reactor effluent stream
Speed.Therefore, the feed bin of the present embodiment is used for the adjustable section in outlet of blanking, can be realized the adjusting of raw material tapping flowrate.
For the uniformity for guaranteeing blanking, in the present embodiment, it is preferable that the axis of 2 adjustment portion 21 of material mouth plug goes out with cavity 10
The axis in material portion 101 coincides, then an axis cricoid and with discharging portion 101 is formed between adjustment portion 21 and discharging portion 101
It is unobstructed and balancedly from discharging gap H outflow to be conducive to raw material in cavity 10, also, is expecting by discharging gap H centered on line
When mouth plug 2 moves up and down and adjusts the size of discharging gap H, the gap H that discharges can be remained is with the axis of discharging portion 101
Center, it is ensured that raw material remains to even drop down during adjusting tapping flowrate.
In the present embodiment, it is preferable that referring to fig. 2, material mouth plug 2 also has a main part 22, and main part 22 is located at adjustment portion
21 top, and main part 22 and adjustment portion 21 are coaxially disposed, i.e. the axis of main part 22 and the axis of adjustment portion 21 coincides,

The main part 22 of taper can make the raw material for falling into discharging portion 101 in cavity 10 when by material mouth plug 2 along main part 22
Outer profile slides downwards, is accumulated on the main part 22 of material mouth plug 2 without stopping, and well can uniformly lead raw material
Enter to discharge in the H of gap；The maximum outside diameter of main part 22 is not less than the maximum outside diameter of adjustment portion 21, then can guarantee along main part 22
The raw material that outer profile slides can fully enter in discharging gap H, without stopping accumulation in the adjustment portion 21 of material mouth plug 2,
It can avoid stopping accumulation on material mouth plug 2 when raw material falls as a result, that is, avoid the hiding of material mouth plug 2 material, reduce blanking dead-space volume.
To avoid the size of 22 couples of main part discharging gap H from impacting, most preferably, the maximum outside diameter of main part 22 is equal to adjustment portion 21
Maximum outside diameter, i.e., the lower end surface of main part 22 is identical as the upper end face size of adjustment portion 21 and is connected to each other, as a result, main body
The lower end in portion 22 will not relative adjustment portion 21 upper end it is prominent and partial occlusion is caused to discharging gap H, to can guarantee discharging
The accuracy of the big minor adjustment control of gap H.
