3 Claims.
This invention relates generally to flame arresting devices such as are employed where highly inflammable vapors or liquids are being handled.
Flame arresting devices of the type to which this invention relates are shown for example in Brooks 1,681,698 and are widely used in the petroleum and gas industries for minimizing lire and explosion hazards. They consist of a hous ing having means for making connection with a storage tank or piping, and a cooling element or tube bank interposed between the inlet and outlet passages of the housing. When in service it is customary to frequently remove the tube bank for cleaning, inspection or possible replacement.
It is an object of the invention to provide an improved llame arrester in lwhich the tube bank may be readily removed and replaced Without disturbing connections to the piping system.
Another object of the invention is to provide a name arrester unit having a simpliiied :body or housing construction, with a part of the housing being attached to and removable with the tube bank.
A further object of this invention is to provide an improved flame arrester having provision for jacking apart sections of the bod?, which are normally clamped together.
Further objects ofthe invention will be apparent from the following description of the preferred embodiment of the same and illustrated in the accompanying drawing.
Referring to the drawings- Fig. 1 is a side elevational view in cross-section, illustrating a flame arrester incorporating the present invention.
Fig. 2 is an end elevational view, partly in cross-section, illustrating a iiame arrester incorporating the present invention.
Fig. 3 is a View of a part of the clamping mechanism taken along the line 3-3 of Fig. 2.
The apparatus as illustrated in Fig. 1 includes a hollow body or housing composed generally of bell-shaped body sections it and Il. These sections are provided with similar flanges I2 and I3 or equivalent means for making connection with the associated piping. Inner enlarged ends of the body sections are provided with flanges ill and l5 which are in parallel spaced planes perpendicular to the central axis of the body.
Between body sections lll and I! there is a flame arrester unit l5 which consists of a cooling element in the form of a tube bank Il surrounded by a rigid annular shell I3. Tube bank Il can consist of alternating layers of flat and lil) corrugated metal strips I9 and 2li Iwound about a central pin or Core 2l, as shown in Brooks 1,681,698. The exterior of the shell can be provided with a plurality of cooling iins 22 to aid heat dissipation. A handle 23 is mounted on one side of the shell for manual manipulation. Shell i8 and tube bank il' are fastened together to form a single unit by means of a bolt 26 which passes through shell h3, tube bank l? and core 2l.
The opposed faces of iianges lll and i5 are provided with machined pads or lands 25 which facilitateinsertion and removal of the shell i8 from between the annular machined faces 26 and 21 of flanges lll and i5.
In order to releasably clamp the body sections lil and li upon opposite sides of the shell, the flanges il and l5 are provided with registering holes to receive bolts 28. These bolts have a loose t in ange lli but are tapped or threaded into flange l5. Bolts 2S may be turned by use of a wrench applied to heads 23 or by use of a rod passed through holes 3G;
In addition to means for clamping the two body parts together, I provide means whereby thel7 can'be jackedV apart to loosen them from the shell it; Thus collars fil are shown attached to the bolts 28 and these collars are positioned as shown in Fig. l, in spaced proximity to the flange lli. The collars are preferably so dimensioned that they are in close proximity with the adjacent peripheral surface of shell IB and thus serve to properly align the unit it with respect to sections and ll.
In addition to the flange openings and bolts previously mentioned I provide corresponding cooperating slots 32 and 33 in flanges lli and l5 respectively. These slots are adapted to accommodate bolts 34 which in turn are adapted to swing about pivoted connections 35 between the webs or ribs on. body ll. Nuts 3l engage bolts 34 and when tightened serve to clamp the anges I4 and l5 together. Bolts 34 are likewise provided with collars Se which are in proximity with the adjacent side portions of shell I3 to align or center the same.
Operation of the above device can briefly be described as follows: Assuming that the body sections Il' and l! are suitably connected to associated piping and that one desires to remove the llame arresting unit l@ from its normal position between sections lll and il, nuts 3l and bolts 23 are loosened whereby body sections lil and l I are likewise loosened with respect to each other. Bolts 3d are swung out of the way and flame arresting unit It is removed laterally from be- 3 tween sections l!) and Il, by grasping the handle 23. In the event sections I3 and II tend to adhere to the ends of shell I8, continuous rotation of bolts 28 will force collars 3| against flange I4 thereby positively jacking sections I0 and II apart.
When replacing flame arresting unit IG the shell I8 is first inserted between pads 25 and then the unit is thrust laterally to its proper aligned position. Bolts 34 are next swung into position as shown in Fig. 3, whereupon nuts 31 and bolts 28 are tightened thereby clamping bodies III and I I against the shell I8 to form a seal. In normal position shell I8 in eifect forms a part of the body and resists inner pressure in the same manner as the walls of the body sections ICI and I I.
I claim:
1. In a :llame arresting device of the character described, a pair of hollow body sections adapted to be connected with piping, a name arresting unit adapted to be interposed between the body sections and comprising a flame arresting core surrounded by a rigid shell, flanges formed on the ends of the body sections adjacent the ends of the shell, a plurality of bolts engaging said anges and serving to draw the body sections into clamping engagement with the ends of the shell, the bolts on one side of the device being pivotally at- Jcached to one of said flanges and engaging in slots in the other flange whereby such bolts can be swung to an out-of-the-way position to facilitate removal and introduction of the llame arresting unit, the bolts on the diametrically opposite side of the device having non-pivotal engagement with said flanges, and collars mounted upon said last mentioned bolts and located adjacent one of said flanges, said collars serving to apply force tending to separate the body sections from engagement with the shell when the bolts mounting said collars are turned in one direction, said collars being dirnensioned to engage the peripheral surface of the shell so that the flame arresting unit is generally centralized with respect to the central axis of the body sections.
2. In a flame arresting device of the character described, a pair of hollow body sections adapted to be connected with piping, a ame arresting unit adapted to be interposed between the body sections and comprising a naine arresting core surrounded by a rigid shell, flanges formed on the ends of the body sections adjacent the ends of the shell, and a plurality of circumferentially spaced bolts engaging said flanges and serving to draw the body sections into clamping engagement with the ends of the shell, the bolts of one side of the device being pivotally attached to one of said flanges and engaging in slots in the other ange, whereby such bolts can be swung to an out-of-the-way position to facilitate removal and introduction of the ame arresting unit, the bolts on the diametrically opposite side of the device having non-pivotal engagement with the flanges.
3. In a llame arresting device of the character described, a pair of hollow body sections adapted to be connected with piping, a flame arresting unit adapted to be interposed :between the body sections and comprising a arne arresting core surrounded by a rigid shell, flanges formed on the ends of the body sections adjacent the ends of the shell, a plurality of circumferentially spaced bolts engaging said flanges and serving to draw the body sections into clamping enga-gement with the ends of the shell, the bolts on one side of the device being pivotally attached to one of said anges and engaging in slots in the other flange, whereby such bolts can be swung to an out-of-the-way position to facilitate removal and introduction of the flame arresting unit, the bolts on the diametrically opposite side of the device having non-pivotal engagement with the anges, and jacking means mounted upon the non-pivotally engaged bolts and serving to apply force to jack the body sections apart with respect to the shell.
