The present invention in tanks or containers such, for example, as those intended for use in the heating and cooling of fluids or liquids, the pasteurizing of milk and cream, or the mixing, blending and sterilizing of various food products, including fruit juices,
syrups, and othermaterials.
One important feature of the invention is to provide in combination with a tank or container, pro-formed insulating cover sections therefor which are constructed for ready application thereto, and which are preferably provided with selfcontained means for connecting the sections one with another and for securing them in position on the container, the latter, however, constituting a complete operating unit, which may be used either with or without the insulating cover sections, depending on Whether or not the material of the container is to be treated or processed by heating and cooling. the same.
Referring to the drawings, the tank is designated generally by the reference numeral Hi and comprises a container H substantially surrounded by a jacket l2 affording a chamber l3 having an inlet it and an outlet l5 through which heating or cooling fluid may be passed to relates to improvements heat or cool the bottom and side walls of the container when desired. The jacket is provided near its upper end with a connection "5 for the reception of a safety valve, not shown. The upper end of the jacket is extended into engagement with the container and is welded thereto, as shown at I! in Fig. 3. "The container is provided with a fluid tight cover or closure I 8 of any suitable design which may be hinged to or otherwise connected with the container.
Attached to the bottom wall I211 of the tank jacket are a plurality of supporting legs each comprising a short section l9 welded or otherwise secured to said wall, and a relatively long section 20 threadedly connected with the section l9 for removal therefrom when desired, the sections 20 each being provided with a foot 2| as shown in Fig. 3. The container H is provided with a downwardly inclined self-draining outlet extension 22 with which is connected a suitable discharge valve 23.
The insulating jacket of the tank is formed of a plurality of side or vertical cover sections designated generally by the reference numerals 24 and 25, Figs, 4 and 5, and an end cover section 26 at the bottom of the tank, Figs. 3 and 9. The vertical sections are each formed of a semicircular sheet 2'! having at its lower end a substantially channel-shaped member 28 provided with an inwardly turned flange 29, Figs. 3 and 7. The upper end of the sheet 21 is provided with an inwardly extending semi-circular member 30 having a lower flange 3| welded to or otherwise secured upon said sheet and an upstanding flange 32 which is adapted to rest against the container l3 and which preferably abuts a shoulder I la thereon in the form of a bead which serves to properly position the vertical insulating sections 24 and 25 on the tank so that the flanges 29 thereof will assume proper relation relative to the edge of the end section 26 when being moved into supporting relation relative thereto. One of the circular sheets 21 is provided with an opening 33 for the reception of a ring 34 adapted to surround the valve connection I6 and to close the opening through which it extends.
Secured within the semi-circular sheet 2'! is a correspondingly shaped sheet of insulating material 35 which may be formed of corkboard or other suitable insulating material, said sheet being secured to the inner face of the semi-circular sheet 21 preferably by cement, as indicated at 36 in Fig. 6.
. The upper end of one of the sheets of insulation is provided with an opening 3'! to receive the fixture l6 on the container when the cover section 25 is applied to the jacket l 2 of the container. The insulating sheet of the opposite cover section is also provided with an opening as indicated at 38 to receive a finish plate or ring 39 suitably secured within the opening formed in the lower end of the circular sheet 27 of the cover section 24, as shown in Fig. 3.
The insulating end cover section 26 of the tank comprises a sheet of metal 40 on which is secured a sheet of insulating material 4| which may be corkboard or other suitable insulating material, said sheet being preferably secured to the metal sheet by means of cement, as indicated at 42 in Fig. 6. It will be noted that the sheet of insulation 4! is of less diameter than the metal sheet 40 so that the latter has an exposed annular portion 40a, the edge of which is seated on the inwardly turned flanges 29 of the semi-circular sheets 21 and the remaining portion of which tank jacket is, therefore,
forms a seat for the lower ends of the semicircular sheets of insulation 35 of the cover sections 24 and 25, as shown in Figs. 3 and 6.
The end cover section 26 of the insulating supported not only by the flanges 29 of the vertical sheets 27 but is also by the flanges 20a of the sections 20 of the tank legs when said sections are screwed into position on the fixed sections l9, as shown in Fig. 3. The metal sheet 40 of the end cover section 25 is provided with openings 43 for the reception of the upper ends of the leg sections 20, and the sheet of insulating material 4| is provided with corresponding openings 43a, as shown in Fig. 9.
The metal and insulating sheets 40 and 4! are also provided with alined openings 44 and 44a, respectively, Fig. 9, for the reception of the outlet member tom wall l2a of the steam container H. Likewise the metal and insulating sheets 4! and M are provided with alined openings 65 and 45a, respectively, for the reception of the steam inlet member I4 which extends downwardly from the bottom wall I 2a of the steam jacket, said inlet and outlet members having suitable valves, not shown, connected therewith for controlling the flow of steam or other fluid or liquid to and from the jacket surrounding the container.
The means for sealing the joints between the adjacent edges of the vertical cover sheets of the insulating sections -24 and 25 is in the form of a finish strip, The strip is designated jacket surrounding the generally by the reference numeral 46 and is formed of a thin sheet of I5 extending downwardly from the bot- I as shown in Figs. 10 to 13, inclusive.
metal which for the greater portion of its length is doubled back upon itself and bent to form the oppositely disposed channel shaped members 41, within which the vertical edge portions 210. of the cover sheets 2'! Figs. 4 and 5. The upper end of the strip 46'has an inwardly offset portion 38 on the opposite sides of which are formed channel members 49 similar to the channel members 41 of Fig. 12. The channel members 49 are adapted to receive the end portions 36a of the inwardly extending members 30 on the upper ends of the semi-circular cover sheets 2'1 when the latter are in assembled relation, as shown in Figs. 1 and 2. The upper extremity 50 of the portion 48 of the strip is parallel to the body of the latter and is adapted to rest on the flange 32 of the member 30 as shown in Fig. 1. The lower end 5! of the finish strip is offset outwardly as shown in Fig. 13, said offset portions overlying the channels 28 of the circular cover sheets 27, as shown in Figs. 1 and 2. With the edges 21a of the sheets 27 extended within the channels 41 of the finish strips, as shown in Fig. 5, it will be seen that the space between said edges is are disposed, as shown in shown in Fig. 10, and has, its side portions 5la bent down upon itself as 7 completely closed and sealed so that dirt'and other foreign matter will be prevented from passing between and behind said cover sheets.
The means for securing the insulating cover sections 24 and 25 on the outer wall of the tank comprises a pair of clamping members 52 and with a that by turning the screws 51 at opposite sides of the tank that the clamping members of each pair will be moved one in the direction or another to tightly clamp the insulating sections 24 and 25 upon the outer wall of the tank. Further more, when this has been done the finish strips 46 will be held in position through frictional engagement of the channel portions 41 thereof with the edges 21a of the circular cover sheets 21.
From the construction shown and described it will be readily apparent that the insulating cover sections 24 and 25 constitute unitary structures which include the means by which they are connected one with another and are secured upon the tank, whereby the application of bolts or other parts to the tank for connecting the sections therewith is made unnecessary. This is also true with respect to the finish strips 46 which are supported entirely by the vertical edge portions of the cover sheets 21 and the extensions 36 thereon.
When applying the insulating sections 24 and 25 to the tank the finish strips 46 will be held in position to permit the opposing edges of the sections to enter the channels of the strips, after which, by tightening the screws 51, the sections will be drawn together and the sheets of insulation urged into engagement with the tank to protect the latter, whereby to maintain more uniform temperatures within the heating or cooling chamber l3 surrounding the container II.
It will be understood that the bottom insulating section 26 is held in position not only by the flanges 29 of the semi-circular cover sheets 21, but also by the flanges 26a of the tank legs 20 after the latter have been screwed into position upon the members l9 which are permanently connected with the bottom wall l2a. of the jacket surrounding the container.
One advantage ofthe present invention lies in the construction of the cover sections 24, 25, and 26, in such a manner that they will be held in assembled relation upon the tank through cooperation of parts of one with parts of another, such, for example, as the clamping members 52 and 53 and associated parts which are permanently connected with the sections, thus avoiding the use of separate or loose parts for this purpose. Moreover, the finish strips for sealing the joints'between the cover sections are so constructed and applied thereto as not to require the use of bolts or other detachable securing parts.
Another advantage of the present construction is that the legs of the tank are designed to support the same regardless of whether or not the insulating cover sections are applied thereto, the legs also serving to hold the bottom cover section in position upon the tank when the tank is to be insulated by use of the sections.
A further advantage results from interconnecting the unitary insulating sections and finish strips so as to insure coaction between the same for the purpose of maintaining the strips in position upon the tank or container, but in a manner which will permit them to be quickly applied to and removed from the tank when desired.
While the tank shown is provided with only two vertical cover sections, itwill be understood that the insulatingjacket may be formed of a greater number of such sections if desired and with a corresponding number of finish strips for sealing the joints between the sections.
It will be further understood that the tank proper can be purchased without the insulating jacket and that subsequently, if the user desires to treat material therein of a nature requiring the tank to be insulated he can purchase the desired number of insulating sections and easily apply them to the tank in a very short time and without difliculty.
