Abstract
A modular rack for mounting components of a phytochemical extraction system is described. The module rack includes at least two legs and one or more frame modules that are each at least 2 units in length. Multiple frame modules can be combined to create racks of width N, where N is an integer greater than 2 units in length. Each frame module may also include mounting devices configured to removably attach extraction columns to the frame module.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 62/360,737, entitled “SOLVENT DEPRESSURIZATION DEVICES, SYSTEM, AND METHODS,” filed on Jul. 11, 2016; and U.S. Provisional Patent Application No. 62/373,284, entitled “EXTRACTION COLUMN FOR A PHYTOCHEMICAL EXTRACTION SYSTEM,” filed on Aug. 10, 2016, the contents of which are incorporated herein by reference in their entireties.
- The present disclosure relates to a modular rack for mounting components of a phytochemical extraction system.
- Typical phytochemical extraction systems include multiple devices, vessels, columns, containers, and the like. Such items are used to hold solvents, coolants, material, and the like. Some of these items may be mounted to a rack or other structure to hold them in fixed positions while they are employed as part of an extraction process.
- Prior art frame designs are static and non-adjustable. The number of columns on the rack, and the size of the rack, are fixed, and this limits the freedom one has to rearrange the machine that hangs on it. In addition, prior art racks typically employ hangers to mount columns. Each hanger requires a pair of wing-nuts or bolts to open and close. These will often fall on the ground and get lost. The inventive modular rack disclosed herein addresses these shortcomings.

FIG. 1 is a first view of a modular rack according to one embodiment. -
FIG. 2 is a second view of a modular rack according to one embodiment. -
FIGS. 3A-3C are perspective, front, and side views of a modular rack. -
FIGS. 4A-4C are perspective, front, and side views of a support leg according to one embodiment. -
FIGS. 5A-5C are perspective, front, and side views of a frame module according to one embodiment. -
FIGS. 6A and 6B are perspective views of attachment devices configured to attach an item to a frame module. -
FIG. 7 is a photograph which shows a detailed view of a column attached to a frame via an attachment device according to one embodiment. - Embodiments described herein provide a modular rack for mounting components of a phytochemical extraction system. As will be discussed further below, the inventive rack provides a foundation that is modular and flexible. The modular rack comprises separate leg segments combined with one or more frame portions. Each frame portion holds either two or three columns. When two legs and one or more frame segments are attached to one another, a rack having an integral width N>=2 can be formed. For example, a length 2 and a length 3 frame portion can be combined with two legs to form rack of width 5. Long spans and/or heavy loads can be accommodated by adding an additional (e.g., third, fourth) leg segment between two frame portions.
- The described rack also provides an improved, easy to use, and stable structure for connecting columns to the rack. The described rack replaces the fasteners (e.g., bolts, wing nuts) associated with hanger-based systems with a pair of compression collets, which are retained on the frame when the column is removed. The described rack thus reduces the action required to mount/de-mount each column to the loosening and tightening of two large nuts. The fastening system is described in more detail with reference to
FIGS. 6A and 6B , below. -
FIG. 1 is a first view of a modular rack according to one embodiment.FIG. 1 depicts amodular rack 100 that carries five extraction andrecovery columns 106 as part of a phytochemical extraction system. Therack 100 includes afirst leg 102 a, asecond leg 102 b, a firstmodular frame 104 a, and a secondmodular frame 104 b. In the illustrated embodiment, the legs and frames are manufactured from steel or other metal tubing. Non-metal implementations are also possible. - Each of the
legs columns 106 and/or other devices attached to therack 100. Example columns are shown and described in U.S. Provisional Patent Application No. 62/373,284, entitled “EXTRACTION COLUMN FOR A PHYTOCHEMICAL EXTRACTION SYSTEM,” filed on Aug. 10, 2016. - Each of the
frames frames legs - The
rack 100 can be configured to provide an attachment surface of varying width, by utilizing multiple modular frames. In the illustrated embodiment,frame 104 a has a width of 2 units, whileframe 104 b has a width of 3 units. The total width of therack 100 is thus 5 units. A unit may be defined as a measure of distance, such as 1 unit=1 foot. Alternatively, a unit may be defined as sufficient width to attach asingle extraction column 106. By utilizing one or more modular frames, a user may configure therack 100 to take on different total widths. For example, where modular frames can have widths of 2 or 3 units, therack 100 can be configured to have any integral total width N>=2. The maximum total rack width of a rack is limited by the strength of the through bolts that connect frames to each other and the legs. While the strength of the bolts will vary with the exact bolt material, dimensions, and thread spacing, a typical one-half inch bolt has a pull-out strength measured in the tens of thousands of pounds. In practice, an extra leg section can be inserted mid-span or every five or six feet of run. A six foot run supports 6 columns per side. Additionally, longer runs can be broken up into individual stand-alone sections, with legs at each end. - In general, if a modular frame has a width of W units, the total rack width is expressed as N=M*W, where M is the number of modular fames employed, and W is the width of a frame module. As discussed, modular frames of differing widths can be used. For example, given modules of width W1 and modules of width W2 (W1<>W2), the total rack width can be expressed as N=M1*+M2*W2.
- The described modular rack provides numerous benefits. First, as discussed above, it can be configured to take on different total widths, thereby adapting to particular applications or environments. Second, the frame can be readily disassembled and collapsed for storage or shipment.

Eachattachment device 502 includes acollet 601 that clamps onto a corresponding steel pin that is welded onto each column. A collet is a segmented band or sleeve that is put around a spindle or shaft and tightened so as to grip the shaft. The collet sleeve has a conical shape, which is compressed into aconical housing 603 as anut 602 is tightened. When the nut is loosened, it impinges on a shelf on the mounting pin, breaking internal friction to push it out. The exploded view ofattachment device 502 illustrates how thenut 602 encloses theperforated collet 601 and compresses it into the receivinghousing 603, which is welded to theframe 104. -
