DEWATERER FOR FLAKED AGAR OR THE LIKE.

Application filed December 4, 1926.

My invention relates to a dewatering apparatus, more 'particularly adapted for dewatering agar .in the processof its production, or any other colloidal substances, and the objects of my invention are: first, to provide a flaked agar dewatering apparatus which will efficiently handle such colloidal substances and separate the water from the agar or other colloidal products; second, to provide an apparatus of this class with means for agitating the agar and water when separating the agar from the water by suction means; third, to provide an apparatus of this class in which the water is drawn from the to a separate reservoir; fourth, to provide an apparatus of this class which is automatic in its action, and fifth, to provide an apparatus of this class which is very simple and economical of construction, durable, efficient in its action, and which Will not readily deteriorate or get out of order.

\Vith these and other objects in View, as will appear hereinafter, my invention consists T of certain novel features of construction, con1- bination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Figure 1 is a side elevational view of my dewatering apparatus, showing some of the parts and portions broken away to facilitate the illustration; Fig. 2 is a partial sectional and elevational view of the same at a right angle to that of Fig. 1, and Fig. 3 is a sectional view of the, stationary central drum portion of the apparatus.

Like characters of reference refer to similar parts and portions throughout the several views of the drawings.

The trough l, agitator 2, leg members 3, brackets 4 and 5, stationary drum 6, revolving drum consisting of the side plates 7 and 8, annular outer plate 9, screen 10, tubes 11, inner "revolving drum 12, gear 13, pinion 1 1, pulleys 15 and 16, drive wheel 17, and scraper 18, constitute the principal parts and portions of my dewatering apparatus.

The trough 1 is a semicircularly formed sheet metal trough and is supported on four legs 3. These legs 3 also support the large brackets 4 and 5, which are in spaced relation Serial No. 152,715.

and annular in form, forming journals for the member 12 to revolve in. The bracket 5, it will be noted, extends downwardly upon the leg 3 on one side and provides a journal for a shaft 15 upon which the pinion 1 1 is mounted and also a pulley 15 and the main drive pulley 17.

Mounted on the lower side of the trough 1 are the journal members 1 and 1 in which is revolubly mounted the agitator 2, which is a twisted sheet metal plate, which is shown best in Fig. 2 of the drawings, provided with a shaft portion, which extends through the journal 1*, and mounted on the end of the shaft extending through the journal 1' is a pulley 16, operated by means of a belt 16 extending over the pulley 15, which is on the main shaft 15*,

Meshing with the pinion 14 is a spur gear 13, which is rigidly secured on the end of the member 12, thus providing means for rev0lv ing the member 12 in the journals formed by the brackets 4 and 5. Positioned in the member 12 is a stationary drum member 6, around which the member 12 revolves. This stationary member 6 isheld from revolving by means of a bracket 1 which is secured to the end of the member 6 and also to the bracket d.

The drum member 6 is provided on its inner side on one side with an inwardly extending portion 6, which is hollow, providing a suction conductor 6 extending from end to end on the interior of the member 6. It is also provided with a pair of rows of holes 6 extending from its exterior to its interior, as shown best in Fig. 3.

Mounted on the end of the member 12 is an annular member 12 by means of bolts 12 adapted to hold the packing 12 for forming a tight joint between the members 6 and 12 at the end.

Mounted in the member 12 are a plurality of radiating tubes 11, which are secured therein by means of lock nuts 11. The inner ends of these tubes are in alinement with and adapted to revolve over the holes 6 in the member 6 with the revolution of the member 12 relative to the member 6. The tubes 11 are provided on their outer ends with flanges 11 on which is mounted the annular member 9. This annular member 9 is provided with a shaft portion 9 over which is mounted a screen 10. This screen 10 is adapted to hold the flaked agar, but permits the water to filter through the screen. It has been found that fine baked. Monel metal screen is preferable to fabric for this filtering purpose. The tubes 9 an screen 1 0, forming 'adrum :for the-flaked .agar to rest against? Mounted on. the one sideof the'trough .1 by means of a bracket 18 'is1the scraper member 18, WhIChGXtGIldS pastthe edge of thetrough at one end, and its other endis placed in juxtaposition to the screen, as shown best in Fig. 1'

of the drawings,adaptcdjto scrapethefiaked dewatered agar fromthescreen andconduct it away from the apparatus;

The operation of the apparatus is as-vfollows:

Agar with the'water ispl acedin the trough 1. The stationary drum 6 is connected with a suction pump by means of the conductor 6, thus providing suction in theinterior of the drum'6 at all times. The drum, consisting of the members 7 to 12,.inclusive, is-revolved by -means of the gear13, pinion e14, shaft 15 and drive wheel 17. The-endsofthe tubes 11 pass over the ports 6 of the member 6. The flaked agar is caused to be drawn against the screen 10 by thesuction, the Water and agar being thoroughly agitated by means of the agitator 2. The Water is drawn from the agar through the screen 10, passes through the tubes 11 into the interior of the'drun 6 and out through the conductor 6 by the suction of the pump, while the flaked agar passes around on the drum and is-scraped from the drum bymeans of the scraper 18 and is conducted away from the-apparatus by means of the extended portion of said scraper.

Though I have shownand described a particular construction, combination and arrangement -'of parts :and Yportions, l Ldoxnot wish tobe limited to 'thisparticular tconstruc- 1 tion, combination :and arrangement, but desire to include in theiscop'esofLmy invention, the construction, ;combination and rearrangement substantiall yiasset'fortlrin:thezappendq 7 ed claims;

from: its interior?to its exterior, a cylindrical member revolublymounted on said "suction;

drum provided with openings thereinaadapt-v ed to communicate with .the ;openings sin'said suction drum, and tubes connectingusaid :ori= fices with the interior surface of L'said filter surface.

2. Inv an apparatus of the class-described,;a semicircular. trough, a. an agitator revolubly mounted in the lower.side.thereofitaudrum provided with a filter surface revolubly mounted with a portion inrsa'id trough, a-suction drum provided withia plurality of orifices from itsinteriortol itsaexterior, a cy linw Y drical member revolublyzmounted on1 said suction drum provided'withl openings therein adapted to communicateawith'tthe openings in said suction drum, tubes connectingsaid orifices with the interior surface of said filter 1 surface, and means' 'for simultaneously revolving said idrumgandsaid agitator.

In testimony whereof; I havehereuntoset my hand at 'San Diego,-Galifornia-, this 27 th day of November, 1928.

JOHN BECKER.
