Abstract
A method of securing corrugated baffles to an interior of a tank in described. Firstly, provide a plurality of generally elliptical shaped baffles. Each baffle has a top, a bottom, a corrugated central portion with corrugations extending between the top and the bottom and uncorrugated generally semi-circular side portions. Secondly, space the baffles transversely along the length of a metal skin out of which the tank is to be formed. Thirdly, roll the metal skin around the baffles and weld the top portion, the bottom portion and the semi-circular side portions of each of the baffles to the metal skin.
Description
-TITLE OF THE INVENTION:
A method of securing corrugated baffles to an interior of a tank.
NAME(S) OF INVENTOR(S):
Ronald Riopel FIELD OF THE INVENTION
The present invention relateæ to a method of securing corrugated baffles to an interior of a tank which i8 mounted onto a truck, trailer or rail car chassis.
R~ ROUND OF THE INVENTION
Baffles are secured within the interior cavities of vehicle mounted tanks in order to retard wave-form liquid movement. In the absence of such baffles, liquid surges can adversely affect the stability of the vehicle.
Corrugated baffles have superior wave dampening ability, as the liquid flow is directed back against itself in a counterflow which retards harmful liquid surges. However, there are numerous problems associated with corrugated baffles.
One problem relates to fit. It is difficult to work in three dimensions and successfully achieve a fit within the tolerances required. Poor fit contributes to a second problem in the form of welding faults.
What is required is an improved method of securing 213637~
-corrugated baffles to an interior of a vehicle mounted tank.
According to one aspect of the present invention there i5 provided a method of securing corrugated baffles to an interior of a tank. Firstly, provide a plurality of generally elliptical shaped baffles. Each baffle has a top, a bottom, a corrugated central portion with corrugations extending between the top and the bottom and uncorrugated generally semi-circular side portions. Secondly, space the baffles transversely along the length of a metal skin out of which the tank is to be formed. Thirdly, roll the metal skin around the baffles and weld the top portion, the bottom portion and the semi-circular side portions of each of the baffles to the metal skin .
The baffle, as described above, is easier to fit for the side portions are uncorrugated. The method, taken as a whole, allows better access and enables a better quality of welding job to be performed.
Although beneficial results may be obtained through the use of the method, as described above, a further problem encountered with some installations relates to cracking along the floor. A tank that is mounted onto a trailer is subjected to longitudinal flexing along the lower or "belly" region which leads to cracking. The baffle is less prone to cracking along the bottom, however, when the baffle is set upon reinforcing pads which serve to buffer the baffle from the effects of longitl7~7; n~ 1 flexing.
According to another aspect of the present invention there is provided a tank which includes a metal skin defining an interior. A plurality of generally elliptical shaped baffles are secured transversely in spaced relation within the interior of the tank. Each baffle has a top, a bottom, a corrugated central portion with corrugations extending between the top and the bottom and uncorrugated generally semi-circular side 2136~74 portions.
For the reasons that are stated above, it i8 preferred that a reinforcing pad be disposed between the metal skin and the bottom of the corrugated central portion of each of the baffles.

DE~TT~D DEBCRIPTION OF THE ~n~nK~v EMBODIMENT
A method of securing corrugated baffles to an interior of a tank will now be described with reference to FIGURES 1 through 6.
Firstly, provide a plurality of generally elliptical shaped baffles 12. Referring to FIGUREB 1 and 2, each baffle 12 has a top 14, a bottom 16, a corrugated central portion 18 with a plurality of corrugations 20 extending between top 14 and bottom 16 and uncorrugated generally semi-circular side portions 22. Secondly, referring to FIGURE 3, weld a reinforcing pad 24 along bottom 16 of corrugated central portion 18 of each of baffles 12. Thirdly, referring to FIGURE
4, space baffles 12 transversely along a length of a metal skin 26 out of which a tank is to be formed. Fourthly, referring to FIGURE 5, roll metal skin 26 around baffles 12 and weld reinforcing pad 24, together with top 14 and semi-circular side portions 22 of each of baffles 12 to metal skin 26. FIGURE
6 illuætrates a tank 10 that results from the teachings of the method. Metal skin 26 defines an interior cavity 28. The plurality of generally elliptical shaped baffles 12 are secured transversely in spaced relation within interior 28 of tank 10.
Reinforcing pads 24 are disposed between metal skin 26 and bottom 16 of corrugated central portion 18 of each of baffles 12.
It will be apparent to one skilled in the art that baffle 12, as described above, is easier to fit in view of the fact that side portions 22 are uncorrugated. It will also be apparent to one skilled in that art that baffle 12, installed as described above, is less prone to cracking along bottom 16 as reinforcing pads 24 serve to buffer baffle 12 from the effects of longitudinal flexing of tank 10. It will also be apparent to one skilled in the art that the generally elliptical baffle can be either circular or oval in shape. It will finally be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
