[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, provides a material transport mechanism, including a containing component 100 and a transport component 200, which solves the problem that conventional reaction containers require manual continuous addition of activated carbon or stirring or heating to enhance the adsorption and decolorization effect.

[0032] Specifically, the containing assembly 100 includes a bin body 101 and an elastic member 102 ; the elastic member 102 is movably disposed inside the bin body 101 .

[0033] Furthermore, the transport component 200 includes a stirring member 201 and a lifting member 202, wherein the stirring member 201 is vertically installed inside the bin body member 101, and the lifting member 202 is sleeved in the interlayer of the bin body member 101, and the two are connected to each other.

[0034] During use, the staff pours the activated carbon and the fermentation liquid into the bin body 101. At this time, the elastic member 102 is pressed down by gravity, so that the elastic member 102 is sealed to prevent the reactants from flowing out to other working spaces; then the stirring member 201 is started, and the reacting substances are fully stirred at this time, so that the activated carbon can fully absorb the substances in the fermentation liquid and enhance the decolorization effect; then when the fermentation liquid is taken out, the gravity on the upper part of the elastic member 102 is reduced and bounced up. At this time, the elastic member 102 is separated inside, revealing a cavity. Due to the rise of the elastic member 102, the stirring member 201 adheres to its surface and sends the adsorbed activated carbon to the next working space. At this time, the lifting member 202 connected to the stirring member 201 rotates synchronously and transports the activated carbon vertically to the upper part of the bin body 102. The transportation process can be used as its storage.

[0035] In summary, by providing the bin body parts and elastic parts, when the fermentation liquid is taken out, the internal activated carbon can be cleaned and enter the conveying stage. By providing the stirring parts and lifting parts, the reaction substances can be stirred. After completion, the used activated carbon can be swept into the space of the next stage and collected. This finally solves the problem that conventional reaction containers require manual continuous addition of activated carbon or stirring or heating to enhance the adsorption and decolorization effect.

[0036] Example 2

[0037] Reference Figure 1~Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment:

[0038] Specifically, the bin body 101 includes an inner bin 101a, an outer bin 101b and a bin cover 101c, wherein the inner bin 101a is coaxially sleeved inside the outer bin 101b, and there is an interlayer A between the two, and there is also an interlayer B on the bin wall of the inner bin 101a for installing the heating wire 301a. The bin cover 101c is connected to the outer bin 101b by a clamp.

[0039] Preferably, the connection between the bin cover 101c and the outer bin 101b is specifically a hinged and clamped connection, that is, when the bin cover 101c needs to be covered, the bin cover 101c is first lifted vertically and then opened, so that the output end of the motor 201c can be smoothly plugged into the main rod 201a.

[0040] Furthermore, the elastic member 102 includes a compression spring 102a, a pressure plate 102b and a sealer 102c, wherein the edge of the pressure plate 102b is in contact with the inner wall of the inner bin 101a and movably sealed, and the sealer 102c is arranged on the side wall and the lower part of the pressure plate 102b, including a blanking hole 102c-1 and a sealing plug 102c-2, which are used to control the sealing and opening of the blanking hole 102c-1 on the side wall of the pressure plate 102b, and several blanking holes 102c-1 are opened through the side wall of the pressure plate 102b, and the sealing plug 102c-2 is vertically installed at the bottom of the inner bin 101a, and the compression spring 102a is placed at the lower part of the pressure plate 102b, which is used to realize the downward pressure and upward movement of the pressure plate 102b.

[0041] Preferably, when the pressing plate 102b is pressed down, the sealing plug 102c-2 is inserted into the blanking hole 102c-1, and the two are in sealed contact. When the pressing plate 102b is rebounded, the sealing plug 102c-2 is separated from the blockage of the blanking hole 102c-1. At this time, the rebounding pressing plate 102b is close to the stirring member 201, so that the activated carbon on the upper part of the pressing plate 102b is stirred and fully falls from the blanking hole 102c-1 into the next functional space.

[0042] Furthermore, the stirring member 201 includes a main rod 201a, a sweeping piece 201b and a motor 201c, wherein the motor 201c is installed on the outside of the bin cover 101c, and its output end passes through the bin cover 101c and is connected to the main rod 201a; the sweeping piece 201b is evenly circumferentially connected to the rod body of the main rod 201a for stirring the reactants; the other end of the main rod 201a passes through the pressure plate 102b, and is connected to the lifting member 202 through the connecting rod 202a-1.

[0043] Furthermore, the lifting member 202 includes a spiral sleeve 202a, a lower discharge port 202b and an upper feed port 202c, wherein the spiral sleeve 202a is installed in the interlayer A and fits with the two vertical side walls of the interlayer A, the lower discharge port 202b is penetrated through the lower side wall of the inner warehouse 101a, and the upper feed port 202c is penetrated through the upper side wall of the inner warehouse 101a.

[0044] Preferably, the positions of the lower discharge port 202b and the upper feed port 202c avoid the position of the heating wire 301a, and a storage box is also provided on one side of the upper feed port 202c for temporarily storing activated carbon or other reactants, which can be added to the inner bin 101a from the upper feed port 202c.

[0045] When in use, the staff adds the reactants into the inner chamber 101a, and the gravity causes the pressing plate 102b to press down and insert into the sealing plug 102c-2, so that the pressing plate 102b can receive the liquid; the chamber cover 101c is closed, and the output end of the motor 201c is connected to the main rod 201a, and the motor 201c is started. At this time, the sweeping sheet 201b fully stirs the reactants to enhance the decolorization effect;

[0046] Next, when the decolorization is completed, the fermentation liquid is taken out, and the gravity is reduced at this time. The pressing plate 102b rises under the reaction of the compression spring 102a, and the drop hole 102c-1 is vacant. Under the stirring of the sweeping sheet 201b, the activated carbon that has not been taken out is fully dropped out of the drop hole 102c-1 and enters the functional space for lifting materials;

[0047] Since the rotating sleeve 202a is connected to the main rod 201a through the connecting rod 202a-1, the rotating sleeve 202a rotates synchronously, and the activated carbon at the bottom is scooped up and lifted to the upper feed port 202c through the threads on its surface wall, either for storage or feeding.

[0048] In summary, by providing the bin body parts and elastic parts, when the fermentation liquid is taken out, the internal activated carbon can be cleaned and enter the conveying stage. By providing the stirring parts and lifting parts, the reaction substances can be stirred. After completion, the used activated carbon can be swept into the space of the next stage and collected. This finally solves the problem that conventional reaction containers require manual continuous addition of activated carbon or stirring or heating to enhance the adsorption and decolorization effect.

[0049] Example 3

[0050] Reference Figure 4 , which is the third embodiment of the utility model, is based on the previous two embodiments, and the difference is that a heating device for fermentation liquid decolorization test is provided, which includes a heating component 300, which achieves the heating effect of the reaction process and the heating and desorption effect of the used activated carbon, and solves the problem of high cost of continuously adding activated carbon to increase the adsorption decolorization effect.

[0051] Specifically, the heating assembly 300 includes an electric heating induction member 301 and a swing member 302, wherein the swing member 302 is installed on the side wall of the bin cover 101c, and the electric heating induction member 301 is installed in the interlayer B and the bin cover 101c respectively, and the two are movably connected.

[0052] Furthermore, the electric heating induction component 301 includes a heating wire 301a, a positive and negative electrode brush head 301b and a positive and negative electrode brush disk 301c, wherein the positive and negative electrode brush head 301b is connected to both ends of the heating wire 301a, and the positive and negative electrode brush disk 301c is rotatably connected to the inside of the compartment cover 101c, and the heating wire 301a is spirally installed in the interlayer B.

[0053] Preferably, the heating wire 301a is formed by winding a long cylindrical ferromagnetic metal, and its two ends are parallel to each other and in the same plane, and the positive and negative brush heads 301b are installed at both ends and are also in the same plane. The side walls of the positive and negative brush disks 301c can be connected to the positive and negative voltages of the power supply. When the positive voltage surface of the positive and negative brush disks 301c contacts the positive brush head of the heating wire 301a, the negative voltage surface contacts the negative brush head. Specifically, the two ends of the heating wire 301a are alternately energized in the positive and reverse directions, and the bin body 101 is heated based on the eddy current principle. The carrier to be heated, such as the inner bin 101a or the spiral sleeve 202a, is made of ferromagnetic metal to facilitate the formation of eddy current phenomenon.

[0054] Furthermore, the swinging member 302 includes a gear 302a, a toothed disc 302b and a connecting rod 302c, wherein the gear 302a is connected to the side wall of the upper end of the main rod 201a, the toothed disc 302b is rotatably connected to the side wall of the bin cover 101c and offset from its axis, and the toothed disc 302b is meshingly connected to the gear 302a.

[0055] Furthermore, a first connecting shaft 302b-1 is connected to the side wall of the gear plate 302b, which is offset from the central axis, and a second connecting shaft 301c-1 is provided on the side wall of the positive and negative brush plates 301c, wherein both ends of the connecting rod 302c are rotatably connected to the first connecting shaft 302b-1 and the second connecting shaft 301c-1 respectively.

[0056] Preferably, when the motor 201c rotates in direction 3, the gear 302a drives the toothed disc 302b to rotate. At this time, the connecting rod 302c reciprocates in direction 4 and drives the positive and negative brush discs 301c to rotate clockwise or counterclockwise within a certain range through the second connecting shaft 301c-1.

[0057] Furthermore, an insulating partition 301c-2 is provided inside the positive and negative brush discs 301c, so that the positive and negative brush discs 301c are divided into two parts, which are respectively connected to the positive and negative poles of the power supply.

[0058] When in use, the staff covers the compartment cover 101c and starts the motor 201c. At this time, the gear 302a drives the toothed disc 302b to rotate, and makes the connecting rod 302c reciprocate in 4 directions, and drives the positive and negative brush discs 301c to rotate clockwise and counterclockwise within a certain range through the No. 2 connecting shaft 301c-1, and finally realizes that the energized positive and negative brush discs 301c alternately energize the heating wire 301a, thereby forming an eddy current phenomenon to heat the device.

[0059] In summary, by setting up electric heating induction parts and swinging parts, the effect of heating the reactants is achieved by using the eddy current phenomenon, and the activated carbon in the lifting and transportation process is heated and desorbed, so that the activated carbon in the device undergoes a desorption and adsorption cycle, which reduces costs and effectively enhances the decolorization effect of the fermentation liquid in the device.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
