CHARLES ALLEN, OF EL PASO, TEXAS.
SLIME-SEPARATOR.1,118,614.
Specification of Letters Patent.
Patented Nov. 24,1914.
Application filed August 3, 1910, Serial No. 575,327. Renewed May 27, 1914. Serial No. 841,369.
To all whom it may concern:
Be it known that I, CHARLES ALLEN,
citizen of the United States, residing at El
Paso, in the county of El Paso and State
5 of Texas, have invented new and useful Im-
provements in Slime-Separators, of which
the following is a specification.
My invention relates to apparatus for set-
tling and separating pulp and slime.
10 The object of the invention is to provide
a simple, practical slime separator of maxi-
mum capacity and efficiency, and it embodies
an apparatus whereby a certain depth of
settled material may be maintained over the
15 outlet of the settling receptacle; in which
the controlling of the discharge from 'the
settling receptacle of the material settled in
it is effected in such manner that it passes
out in proportion to the quantity settling in
20 the receptacle so long as the quantity does
not exceed the capacity of the discharge ori-
fice; in which the limitation of the quantity
of settled particles discharged during any
given time prevents the choking of the in-
25 verted siphon; when no solid particles are
entering the receptacle, no solid particles
are discharged therefrom, nor is any water
discharged from the outlet for the solid par-
ticles; in which the quantity of water for
30 removing the settled solids does not pass
through the discharge orifice for the solids,
but is under separate control; this water
for the removal of the solids being taken
from the overflow of the receptacle or from
35 an outside source; to provide for an econ-
omy in the use of the water employed for
removing the settled solids whereby the
quantity of water so used does not exceed
the volume necessary to carry with it the
40 maximum quantity of solid particles that
can pass through the discharge orifice from
the receptacle; hence the settled discharge
solids can be almost free from accompany-
ing water; to provide means for automati-
45 cally regulating the separate water flow, and
discharging the solids proportionally with
the settling of the solids in the receptacle;
to provide means whereby a true level of the
overflow, periphery of the receptacle is se-
50 cured and maintained.
There are other objects and advantages
which will be apparent hereinafter.
The invention consists of the parts and
the construction and combination of partsas hereinafter more fully described and 55
claimed, having reference to the accompany-
ing drawings, in which-
Figure 1 is a vertical section through the
machine. Fig. 2 is a plan view thereof.
Fig. 3 is a plan view of the valve seat. Fig. 60
4 is a detail of the key and removable section
of the valve seat. Fig. 5 is a plan view of
the plate which holds the valve seat in place.
Fig. 6 is a detail in section of the means for
adjusting the rim of the settling tank. 65
A represents a settling receptacle of suit-
able size, shape and material. Preferably it
is in the form of a cone, and ordinarily it is
made with its sides at an angle of 550 to 700.
It is appropriately mounted on the frame B. 70
2 is a similar cone immersed in the water
contained in cone A and buoyed up by an air
chamber 3. The buoyancy of the air cham-
ber 3 may be varied by means of the water
pipe 4 and air cock 4', by letting in the 75
water and letting out a corresponding
amount of air.
5 is a casting fastened to and surround-
ing the inverted apex portion of the cone,
and from which casting the settled material 80
in cone 2 discharges into the inverted, sta-
tionary receptacle or cone A.
7 is a valve stein or rod suitably support-
ed, as shown at 6, centrally within the cone
2 and extending down through the discharge 85
from cone 2 into the cone A, and carrying
on its lower end a valve plate 8 which con-
trols the discharge from the orifice 9 in the
inverted apex of the receptacle A.
10 is a replaceable plate forming a valve 90
seat for the valve plate 8. This replaceable
plate 10 is smooth on both sides where it
bears against the other parts. It has a
downwardly projecting, annular knife-edge
105, against which the plate 8 seats, as 95
shown. This downwardly projecting, knife-
edge 10' with the annular depression on the
under side of the plate 10 insures the tight
closing of the discharge orifice 9 and with-
out this construction the sand on the plate 100
8 would be likely to get between it and the
valve seat and prevent a proper closure.
In order to allow the platu 10 to be removed
or replaced at any time without dismantling
the machine, one side of the plate is pro- 105
vided with a radial wedge or key 10', Fig.
4, fitting a slot 10 in tho plate, whereby on
withdrawing the plug or wedge 10' plate 10
