Take one Room, polyhedron constant volume chamber as example, the volume calculation method is described:
Among Fig. 8, summit BCDFGM forms a triangular prism cone, a1 is constant volume one Room base plate tip-over angle, scope is 0 ~ 40 °, a0 is the powder angle of repose, and W1 is constant volume one Room width, and L1 is constant volume one Room floor length, H1 is constant volume one Room riser height, and H0 is the height of side, constant volume one Room riser distance from bottom constant volume one Room minimum level face.
The volume that set to hold a Room is V1, and volume (cavity that summit ABDEFM forms) is V0 below the base plate.Then:
V0=L1*H0*W1/2=(ctg(a1)H0)*H0*W1/2=(ctg(a1))*H0
2*W1/2 (1)
V1=L1*(H0+H1)*W1/2-V0=(ctg(a0)*(H0+H1))*(H0+H1)*W1/2-V0
=((ctg(a0))*(H0+H1)
2*W1-(ctg(a1))*H0
2*W1)/2 (2)
Can be found out that by formula (2) constant volume chamber volume is the function of powder angle of repose a0, base plate tip-over angle a1, constant volume one Room width W 1 and height H 0, H1, that is:
V1=f(a1,a0,H0,H1,W1) (3)
Because for a certain powder, angle of repose a0 fixes, constant volume chamber width W 1 can pre-determine, and a1 also can pre-determine according to powders property and airing form.H0 is associated with a1, L1, and H0 and L1 can represent with a variable, like this, as long as determine a1, and pre-determine H0, and V0 has just determined.Therefore, formula (3) in fact can be expressed as formula (4):
V1=f1(H1) (4)
Therefore, under the prerequisite that physical parameter and other structural parameter are determined, constant volume one Room volume is the function of constant volume chamber riser height H 1.If physical property changes, a0 changes thereupon, and a1, H0, W1 can adjust as required, and behind definite a1, H0 and W1, according to target volumeter is calculated H1 and got final product.
Take class right cylinder constant volume one Room as example, the volume calculation method is described:
Among Fig. 9, d1 is body diameter, and a1 ' is constant volume one Room base plate inclination degree, and a0 ' is the powder angle of repose.H0 ' is the height of side, constant volume one Room perigee distance constant volume one Room minimum level face, and H1 ' is the shortest side, constant volume one Room height.As shown, summit B ' C ' D ' E ' forms a cylinder shape cavity, i.e. constant volume one Room, and V1 ' is the volume of constant volume one Room.V0 ' is the external cavity volume of summit A ' B ' E ' composition, V
CylinderBe cylinder volume among the figure:
V0 '=S1 '
The end* H0 '/2=(Pi*d1
2)/4*H0 '/2
=(Pi*(ctg(a1′)*H0′)
2)/4*H0′/2=Pi*(ctg(a1′))
2*H0′
3/8
=f′(a1′,H0′) (5)
In the formula (5): Pi=3.14159
Constant volume one Room volume V1 ':
V1 '=V
Cylinder-V0 '=((Pi*d '
2)/4) * (H0 '+H1 ')-V0 '
=((Pi*(ctg(a0′)*(H0′+H1′))

=Pi*(ctg(a0′))
2*(H0′+H1′)
3/4-V0′
=f0′(a0′,a1′,H0′,H1′) (6)
Can find out that by formula (6) V1 ' is a0 ', a1 ', H0 ', the function of H1 '.For a certain specific powder, a0 ' fixes, a1 ', and H0 ' can pre-determine on request, and like this, V1 ' is H1 ' function just, that is:
V1′=f1′(H1′) (7)
Powder volumetric feeder method of the present utility model both can manual operation, again can automatization control.Two kinds of operating method all are that the stopping valve on the loading line is operated, and comprise the steps:
Step 1: after the power of relying on for support of the powder in the powder hopper (1) entered constant volume one Room (7) and is full of from the powder discharge orifice (17) of powder hopper, powder is static to be rested in constant volume one Room (7); Because the existence of the own angle of repose of powder, thus powder can not flow in the horizontal direction far, but form one tapered, it is indoor that powder just is blocked in constant volume one.
Step 2: when need during to constant volume two Room (8) feed, a valve (22) is ended in constant volume one Room on operation inflation one pipeline, and to constant volume one Room (7) inflation, the powder of constant volume one Room enters constant volume two Room (8) from the first powder discharge orifice (18); After constant volume two Room (8) were full of, powder is static to be rested in constant volume two Room (8); Tail gas is then discharged constant volume one Room (7) by exhaust one pipe (2).
Step 3: when need during to constant volume three Room (9) feed, two valves (23) are ended in constant volume two Room on operation inflation two pipelines, and to constant volume two Room (8) inflation, the powder of constant volume two Room (8) enters constant volume three Room (9) from the second powder discharge orifice (19); After constant volume three Room (9) were full of, powder is static to be rested in constant volume three Room (9); Tail gas is then discharged constant volume two Room (8) by exhaust two pipes (3).
Step 4: when need in the material receiving device (21) during feed, three valves (24) are ended in constant volume three Room on operation inflation three pipelines, inflate to constant volume three Room (9), powder in constant volume three Room (9) flows into tremie pipe (10) from the 3rd powder discharge orifice (20), thereby enters material receiving device (21); Tail gas is then discharged constant volume three Room (9) by tremie pipe (10), vapor pipe (25) also can be set in constant volume three Room (9) be used for last person's gas.
Wherein, to the indoor gas that is filled with of constant volume, can be pressurized air, also can be non-compression high-pressure air, can be air, also can be other gas.
Compare with the tubular constant volume blanking that generally adopts, this volumetric feeder is eliminated all mechanical moving elements, and mainly utilizes the waste gas in the electrolyzer production process.Therefore, this device is non-maintaining device, and greatly saves the energy.Again because simple in structure, thereby investment reduces greatly.In addition, owing to adopted three (and more than) constant volume cell structures, eliminated the impact of eminence constant volume chamber on constant volume chamber, bottom, so constant volume guaranteed, and the constant volume chamber is more, constant volume is more accurate.
