Description

Technical Field

[0001] This invention relates to the field of dye processing technology, and more specifically, to an organic dye and its preparation process. Background Technology

[0002] Pure natural organic dyes are mainly plant dyes, which can be classified according to their chemical composition into carotenoids, anthraquinones, naphthoquinones, flavonoids, curcumin, indigo compounds, and chlorophyll compounds, etc.

[0003] Solvent extraction is widely used because of the low cost of extractants, simple equipment, and convenient operation. Solvent extraction methods include maceration, percolation, decoction, and reflux extraction.

[0004] Natural pigments can be extracted using water as a solvent through maceration and decoction. The former is suitable for raw materials whose active ingredients are soluble in water and are stable to moisture and heat and do not easily volatilize. For extraction with organic solvents, reflux extraction can be used.

[0005] Curcumin in turmeric can be extracted using organic solvents such as methanol, ethanol, acetone, and ethyl acetate.

[0006] However, the solvent extraction methods mentioned above all require the plant dye raw materials and extractant to be placed in a container and kept at a certain temperature. When using organic solvents as extractants, the container must be kept sealed to avoid the toxic gases produced by the evaporation of organic solvents from posing health risks to the operators. However, this also makes it inconvenient for operators to stir the plant dye raw materials and extractant. Summary of the Invention

[0007] To increase the convenience of small-batch dye extraction operations and reduce the difficulty of stirring and the health effects of extractant vapors, this invention adopts the following technical solution:

[0008] The purpose of this invention is to provide a solution for placing a closed spherical container in a constant temperature container. Plant dye raw materials and extractants are added into the closed spherical container. By shaking the spherical container, the closed nature of the spherical container and its easy rolling characteristics are utilized to reduce the difficulty of stirring and the health effects of extractant vapor.

[0009] To achieve the above objectives, the present invention provides a process for preparing organic dyes, comprising the following steps:

[0010] Step 1: Inject the plant dye raw materials and extractant into the spherical tank;

[0011] Step 2: Place the ball tank in a constant temperature chamber, add water to the chamber and control the water temperature to be consistent with the temperature required for dye extraction;

[0012] Step 3: Control the shaking and rolling of the spherical tank in the constant temperature chamber to ensure that the plant dye raw materials and extractant in the spherical tank can come into full contact.

[0013] The organic dyes prepared using the organic dye preparation process of this application are one of the following: carotenoids, anthraquinones, naphthoquinones, flavonoids, curcumin, indigo, and chlorophyll. Attached Figure Description

Detailed Implementation

[0024] To increase the convenience of small-batch dye extraction operations and reduce the difficulty of stirring and the health effects of extractant vapors, this invention provides an organic dye preparation process, comprising the following steps:

[0025] Step 1: Inject the plant dye raw materials and extractant into the spherical tank 21;

[0026] Step 2: Place the ball tank 21 in the constant temperature chamber 11, add water to the constant temperature chamber 11 and control the water temperature to be consistent with the temperature required for dye extraction;

[0027] Step 3: Control the spherical tank 21 to shake and roll inside the constant temperature chamber 11 so that the plant dye raw materials and extractant inside the spherical tank 21 can come into full contact.

[0028] The organic dyes prepared using the organic dye preparation process of this application are one of the following: carotenoids, anthraquinones, naphthoquinones, flavonoids, curcumin, indigo, and chlorophyll.

[0029] The following describes specific embodiments of the present invention.

[0030] Reference Figure 4-5 The illustration shows an embodiment of the organic dye preparation process provided by the present invention, in which the rotating receiving roller 16 drives the spherical tank 21 to roll within the constant temperature chamber 11:

[0031] The constant temperature chamber 11 of this application is equipped with two receiving rollers 16 on its inner side. The side surface of the ball tank 21 can abut against the side of the receiving roller 16, and multiple ball tanks 21 can be placed on the two receiving rollers 16 at the same time.

[0032] The receiving roller 16 can be rotatably installed inside the constant temperature chamber 11. The rotation of the receiving roller 16 can be driven by a motor. Start the motor to drive the spherical tank 21 to roll inside the constant temperature chamber 11, so that the plant dye raw materials and extractant inside the spherical tank 21 can be fully contacted.

[0033] Since the spherical tank 21 is closed, the plant dye raw materials and extractant inside the spherical tank 21 can be stirred by controlling the rotation of the spherical tank 21. This can increase the convenience of small-batch dye extraction operations and reduce the difficulty of stirring and the health effects of extractant vapor.

[0034] The constant temperature chamber 11 and the receiving roller 16 have built-in electric heating components, which can be heating wires or electric heating rods.

[0035] Reference Figure 3 The diagram illustrates the specific structure of the oscillation aid used in the organic dye preparation process provided by this invention:

[0036] The spherical tank 21 of this application is provided with an oscillation aid. The oscillation aid is detachably installed inside the spherical tank 21, and the end of the oscillation aid and the outer surface of the spherical tank 21 can be on the same virtual spherical surface.

[0037] Specifically: The main body of the oscillation aid is a group of multiple intercepting columns 23. The two ends of the multiple intercepting columns 23 are respectively fixedly connected to the disk body 24. The disk body 24 is fixedly connected to the spherical cover 26 through a group of multiple springs 25. The two ends of the springs 25 are respectively welded and fixedly connected to the disk body 24 and the spherical cover 26. The spherical cover 26 is detachably fixedly connected to the spherical tank 21 by magnetic adsorption or fasteners.

[0038] The spherical cover 26 and the outer surface of the spherical can 21 can be on the same virtual sphere, which increases the free rolling effect of the spherical can 21.

[0039] Reference Figure 3-6 The illustration shows an example of the organic dye preparation process provided by the present invention, which uses an oscillation aid to further increase the contact effect between the plant dye raw material and the extractant in the spherical tank 21:

[0040] The spherical tank 21 of this application has openings at both ends, and two spherical covers 26 can seal the openings at both ends of the spherical tank 21. Specifically:

[0041] The projected size of the spherical cover 26 at one end along the opening direction is the same as the opening size, and it can slide freely inside and outside the opening; the spherical cover 26 at the other end is provided with a limiting edge, which can be embedded in the embedding edge 22 installed at the end opening of the corresponding spherical tank 21.

[0042] Due to the use of multiple springs 25 on both sides, during the rolling and shaking of the spherical tank 21, the springs 25 further drive the two discs 24 and multiple intercepting columns 23 to shake together, increasing the contact effect between the plant dye raw materials and the extractant inside the spherical tank 21.

[0043] Furthermore, the use of multiple springs 25 on both sides to open and close the spherical cover 26 on one side increases the efficiency of adding and discharging plant dye raw materials and extractants into the spherical tank 21.

[0044] The diameter of the disc 24 is not greater than the diameter of the end opening of the spherical tank 21.

[0045] Multiple protrusions 231 are fixedly connected to the inner side of the intercepting column 23. Under the limiting action of the protrusions 231, the plant dye raw material is fully moved during the shaking of the two discs 24 and the multiple intercepting columns 23.

[0046] Among them, filter gauze can be wrapped around the outside of multiple interception columns 23 to increase the convenience of collecting organic dye products;

[0047] By using non-powdered plant dye raw materials and combining them with the above-mentioned scheme of this application, it is possible to remove residues while ensuring dye extraction efficiency.

[0048] The gauze can be made of one of the following materials: plastic, cotton, or steel wire.

[0049] Reference Figure 4-8 The following is a specific embodiment illustrating the organic dye preparation process provided by the present invention, which increases the contact effect between the plant dye raw material and the extractant in the spherical tank 21:

[0050] As a further improvement of this application, a movable pressure roller 14 and a rotating abutment roller 15 are installed on the upper side of the ball tank 21 to further limit the movement range of the ball tank 21 and increase the stability of the ball tank 21 during the shaking motion.

[0051] Specifically: the sides of the movable pressure roller 14 and the rotating abutment roller 15 can abut against the spherical tank 21, thereby increasing the limiting effect on the spherical tank 21 and improving the shaking efficiency and stability of the spherical tank 21 when there is less material inside the spherical tank 21. In this state, the receiving roller 16 is fixedly connected inside the constant temperature box 11.

[0052] The rotating abutment roller 15 is rotatably mounted on the upper side of the constant temperature chamber 11, and a reduction motor for driving the rotating abutment roller 15 to rotate is installed on the outside of the constant temperature chamber 11.

[0053] On the other side of the constant temperature chamber 11, which is equipped with a rotating abutment roller 15, a movable pressure roller 14 is provided. The movable pressure roller 14 is fixedly connected to the L-shaped arm. The L-shaped arm is rotatably mounted on the slide block 13. The slide block 13 is slidably connected inside the U-shaped cover 12 on the side of the constant temperature chamber 11.

[0054] The position of the L-shaped arm on the slide block 13 is controlled to provide space for the ball tank 21 to be placed. When the movable pressure roller 14, the rotating abutment roller 15 and the two receiving rollers 16 simultaneously abut against the side of the ball tank 21, the range of movement of the ball tank 21 is limited.

[0055] The L-shaped arm is locked in position with the slide block 13 by fasteners.

[0056] Multiple anti-slip pads 141 are evenly spaced on the side of the movable pressure roller 14, and multiple anti-slip protrusions 151 are evenly spaced on the periphery of the rotating abutment roller 15.

[0057] The sides of the anti-slip pad 141 and the anti-slip protrusion 151 are connected to the outer side of the spherical tank 21 by friction drive.

[0058] Both the anti-slip pad 141 and the anti-slip protrusion 151 can be made of materials that can be elastically deformed, such as rubber.

[0059] The movement of the movable pressure roller 14 along its own axis can be achieved by installing a telescopic actuator on the U-shaped cover 12 to drive the movement of the slide block 13.

[0060] The telescopic actuator of this application can be an electric telescopic rod or a hydraulic cylinder;

[0061] Start the geared motor to drive the rotating abutment roller 15 to rotate. Under the action of the anti-slip protrusion 151, the spherical tank 21 continuously rolls between the movable pressure roller 14, the rotating abutment roller 15 and the two receiving rollers 16, so that the plant dye raw materials and extractant in the spherical tank 21 can be fully contacted.

[0062] Start the telescopic drive to drive the movable pressure roller 14 to move back and forth along its own axis. Under the action of the anti-slip pad 141 and the anti-slip protrusion 151, the spherical tank 21 is made to swing back and forth between the movable pressure roller 14, the rotating abutment roller 15 and the two receiving rollers 16, which further increases the contact effect between the plant dye raw materials and the extractant in the spherical tank 21.

[0063] Reference Figure 4 and Figure 6 The following is an example illustrating the organic dye preparation process provided by the present invention, which controls the spherical tank 21 to rotate and shake simultaneously, thereby increasing the contact effect between the plant dye raw materials and the extractant within the spherical tank 21:

[0064] One end of the rotating abutting roller 15 of this application extends outward to the constant temperature box 11 to form a driving end, and the other end of the rotating abutting roller 15 extends outward to the constant temperature box 11. A turntable 33 is fixedly installed at its end, and the turntable 33 is connected to the slide 13 through a synchronous driving assembly.

[0065] Specifically: The main body of the synchronous drive assembly is the connecting rod 31. The two ends of the connecting rod 31 are rotatably mounted with hinge joints. The hinge joints on both sides are rotatably connected to the extension arm 32 and the turntable 33, respectively. The extension arm 32 is fixedly connected to the slide block 13. A reduction motor for driving the rotating abutment roller 15 to rotate is installed on the outside of the constant temperature box 11. The output shaft of the reduction motor is connected to the drive end through a coupling.

[0066] Start the reduction motor and control the rotation of the rotating abutment roller 15 to rotate, so that the turntable 33 drives the extension arm 32 to move through the connecting rod 31, so that the slide 13 can slide back and forth in the U-shaped cover 12, thereby controlling the spherical tank 21 to rotate and shake at the same time.

[0067] During this process, the connecting rod 31 rotates with the hinge joints connected to both ends of the connecting rod 31, and the hinge joints on both sides rotate with the extension arm 32 and the turntable 33 respectively.

[0068] By controlling the spherical tank 21 to rotate and shake, the contact effect between the plant dye raw materials and the extractant inside the spherical tank 21 is increased, and the driving efficiency of the equipment is improved, while the number of driving components is reduced, thereby increasing economic benefits.
