Description

Technical Field

[0001] The present invention relates to the technical field of wood vinegar purification, and particularly to a purification and extraction device for antibacterial active components of wood vinegar. Background Art

[0002] Wood vinegar is an organic liquid obtained by condensing, recovering, and separating the gas generated during the pyrolysis and carbonization of biomass such as wood containing cellulose and hemicellulose. It is a green chemical product that is non-toxic to humans and animals, and contains various components with antibacterial and antioxidant effects. Therefore, people often extract the active components with antibacterial effects from wood vinegar according to the usage requirements.

[0003] The relatively common extraction device in the existing technology is the centrifugal extraction device. Centrifugal extraction (extraction) is an efficient liquid-liquid extraction and separation technology, which mainly realizes separation based on the difference in the solubility of substances in different solvents and the action of centrifugal force. In the existing technology, when carrying out extraction and purification work through the centrifugal extraction device, the raw material and the extraction liquid need to be mixed and reacted outside the centrifugal equipment to generate an emulsion, and then the emulsion is injected into the centrifugal extraction equipment, and then the centrifugal extraction device is started for centrifugal extraction. This working method of mixing first and then injecting requires the cooperation of multiple devices, increasing the production cost and prolonging the working time, and thus the working efficiency is relatively low and cannot meet the actual production requirements.

Detailed implementation manners

[0035] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0036] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below. Embodiment

[0037] Referring to Figures 1 - 11 , which is an embodiment of the present invention, includes a purification and extraction device for the antibacterial active components of wood vinegar liquid, including a receiving unit 1 and a driving unit 2. The driving unit 2 includes a motor 21, an adapter seat 22 disposed below the motor 21 and extending into the receiving unit 1, a driving component 23 vertically inserted into the axis of the adapter seat 22, a plurality of groups of limiting components 24 equally divided and disposed below the adapter seat 22, and a stirring component 25 disposed on the driving component 23; the motor 21 provides the power for stirring and mixing and centrifugally rotating the drum 13, the driving component 23 and the limiting component 24 are used to limit and assist the stirring component 25 to perform the stirring and mixing operation, and the stirring component 25 is used to stir and mix the raw materials and the extraction liquid located in the drum 13;

[0038] The limiting component 24 includes symmetrically arranged first limiting rod 241 and second limiting rod 242, and a plurality of groups of teeth 243 opened on the inner side surface of the first limiting rod 241; combined with Figure 9, since the outer end of the stirring member 25 is limited by the first limiting rod 241 and the second limiting rod 242, and the first limiting rod 241 is fixedly connected to the end of the adapter base 22, when the driving member 23 pushes the stirring member 25 through the thread on the threaded shaft 231, the stirring member 25 can displace in the vertical direction along the threaded shaft 231 under the limitation of the limiting member 24;

[0039] The stirring member 25 includes a mounting base 251 connected to the driving member 23, a clamping assembly 252 rotatably connected below the mounting base 251, a support spring 253 sleeved on the clamping assembly 252, and multiple groups of stirring assemblies 254 distributed outside the mounting base 251; Figure 11 , when the threaded shaft 231 rotates, it can drive the mounting base 251 to move vertically along its axis through its own thread, thereby assisting in achieving the purpose of stirring and mixing at different depth positions in the drum 13, and the clamping assembly 252 rotatably connected below the mounting base 251 will also move vertically following the mounting base 251;

[0040] The clamping assembly 252 includes a sleeve shaft 2521 sleeved on the threaded shaft 231, the top end of the sleeve shaft 2521 is rotatably connected inside the mounting base 251, a second clamping seat 2522 fixedly arranged at the lower end of the sleeve shaft 2521, and a slider 2523 horizontally and fixedly connected inside the sleeve shaft 2521;

[0041] The stirring assembly 254 includes a horizontal shaft 2541 horizontally and rotatably connected outside the mounting base 251, a gear 2542 fixedly arranged on the horizontal shaft 2541, and the gear 2542 meshes with the teeth 243 inside the first limiting rod 241.

[0042] Among them, the clamping assembly 252 further includes a support spring 253 located between the clamping assembly 252 and the mounting base 251, the number of the stirring assemblies 254 is the same as the number of the limiting members 24, and the support spring 253 always elastically supports between the mounting base 251 and the clamping assembly 252.

[0043] Among them, the stirring assembly 254 further includes two groups of limiting disks 2543 symmetrically arranged on both sides of the gear 2542, and the two groups of limiting disks 2543 respectively abut against both sides of the limiting member 24, and the outer end of the horizontal shaft 2541 passes through between the first limiting rod 241 and the second limiting rod 242; Figure 11 , multiple groups of blades are arranged on the horizontal shaft 2541, and the end of the horizontal shaft 2541 is rotationally limited and connected to the mounting base 251, so the mounting base 251 can synchronously drive the stirring assembly 254 to displace in the vertical direction. When the stirring assembly 254 displaces in the vertical direction, the vertically moving gear 2542 will mesh with the teeth 243 (refer to Figure 9Therefore, the entire stirring component 254 rotates around the horizontal axis 2541, thereby realizing the action of self-rotation stirring.

[0044] Among them, the top end of the driving component 23 is connected to the motor 21 upward, and the end extends downward into the accommodating unit 1. The driving component 23 includes a threaded shaft 231 connected to the motor 21, and the threaded shaft 231 is provided with threads. A smooth shaft 232 is arranged at the end of the threaded shaft 231, and the outer wall of the smooth shaft 232 is smooth without threads. And a limiting groove 233 is vertically opened on the threaded shaft 231 and extends into the smooth shaft 232, and the slider 2523 is slidably inserted into the limiting groove 233. Combined with Figure 4 , the stirring component 25 is threadedly connected to the threaded shaft 231, so it can be pushed by the threads within the threaded range of the threaded shaft 231. However, the smooth shaft 232 does not have threads. Therefore, when the stirring component 25 moves onto the smooth shaft 232, it will disconnect the threaded connection with the threaded shaft 231. Since the slider 2523 is inserted into the limiting groove 233, and there is no obstruction in the circumferential direction between the mounting seat 251 and the clamping component 252, the threaded shaft 231 can drive the mounting seat 251 and the clamping component 252 to move in the vertical direction, and at the same time drive the clamping component 252 to rotate circumferentially. The second clamping seat 2522 can be clamped with the first clamping seat 131. Therefore, when the second clamping seat 2522 is clamped with the first clamping seat 131, the clamping component 252 can be connected to the rotating drum 13, and the rotating drum 13 can be driven to rotate circumferentially synchronously.

[0045] During use, the extractant and the raw material are placed in the rotating drum 13. The motor 21 is started to drive the driving component 23 to rotate. The rotating driving component 23 drives the mounting seat 251 to move through the threads of the threaded shaft 231. Under the cooperation and limitation of the limiting component 24, the mounting seat 251 will drive the entire stirring component 25 to move in the vertical direction. During the vertical movement of the stirring component 25, the limiting component 24 rotates around the horizontal axis 2541 through the meshing of the gear 2542 and the limiting groove 233. The rotating stirring component 254 can directly stir and mix the extractant and the raw material located in the rotating drum 13, simplifying the operation steps in the prior art of mixing externally and then injecting it into the rotating drum 13, thereby shortening the operation time required, and further achieving the purpose of improving work efficiency. And through the mutual cooperation of the vertical displacement of the stirring component 25 and the self-rotation stirring of the stirring component 254, the device can stir the liquid at different depth positions, thereby avoiding the generation of mixing dead angles, ensuring the mixing effect, and forming multiple stirring turbulences in different latitudes, enhancing the stirring effect, making the raw material mixing more uniform, and further ensuring the mixing effect of the raw material and the extractant.

[0046] The accommodating unit 1 includes a base 11, a shell 12 arranged on the base 11, a drum 13 vertically inserted into the shell 12, a first holder 131 arranged on the inner side of the axial position of the bottom end of the drum 13, and an infusion component 14 arranged at the top of the shell 12. The base 11 provides support for the entire device, the shell 12 is an external protection measure for the device, the drum 13 is a place for the raw material and the extractant to react, and the drum 13 is rotatably connected in the shell 12, and the infusion component 14 is a channel for the raw material, the extractant and the purified substances to enter or be discharged.

[0047] Among them, combined Figure 8 The infusion component 14 includes a cover plate 141 arranged on the top of the shell 12, and the inner cavity of the cover plate 141 is connected with the drum 13 as a whole, a first weir plate 142 is arranged inside the infusion component 14, and one end of the first weir plate 142 extends outward through the cover plate 141 to the outside, a second weir plate 143 is arranged above the first weir plate 142, and the outer end of the second weir plate 143 extends outward to the outside of the cover plate 141, a first injection pipe 144 and a second injection pipe 145 are symmetrically arranged on both sides of the top of the cover plate 141, and the first injection pipe 144 and the second injection pipe 145 are both connected with the inside of the cover plate 141, the first injection pipe 144 and the second injection pipe 145 are used to inject raw materials and extractants, and the second weir plates 143 and the second weir plates 143 are used to discharge substances to be extracted by centrifugal separation.

[0048] Further, combined with Figure 8 The diameter of the first weir plate 142 is smaller than the inner diameter of the cover plate 141, and the first weir plate 142 is coaxial with the cover plate 141. A first output groove 1421 is provided inside the first weir plate 142, and one side of the first output groove 1421 passes through the cover plate 141 and is connected to the outside. A first overflow port 1422 having a smaller diameter than the first weir plate 142 is provided at the bottom end of the first weir plate 142, and the inner cavity of the cover plate 141 is connected to the first output groove 1421 through the first overflow port 1422. There is a clearance opening between the outer wall of the first weir plate 142 and the inner wall of the drum 13. 1423, when the materials in the drum 13 and the cover plate 141 are subjected to centrifugal force and undergo centrifugal motion, the materials located near the axis position may be blocked by the first weir plate 142, and then enter the first output groove 1421 through the first overflow port 1422, and are output outward through the outer end of the first output groove 1421 to complete the centrifugal extraction work. However, since the diameter of the first weir plate 142 is smaller than the inner diameter of the drum 13, the materials close to the inner wall of the drum 13 may continue to be transported upward to the second weir plate 143 through the yield port 1423.

[0049] Further, combined with Figure 8, the second weir plate 143 is fixedly connected above the inner side of the cover plate 141. A second output groove 1431 is formed inside the second weir plate 143, and one side of the second output groove 1431 penetrates through the cover plate 141 to communicate with the outside. A second overflow port 1432 with a diameter smaller than that of the first weir plate 142 is formed at the center position of the second weir plate 143, and the second overflow port 1432 connects the inside of the cover plate 141 with the second output groove 1431. The substances transported to the second weir plate 143 will be blocked by it and guided into the second output groove 1431 through the second overflow port 1432, and finally output through the second output groove 1431.

[0050] Further, in combination with Figure 3 , blocking components 15 are installed in both the first injection pipe 144 and the second injection pipe 145. The blocking component 15 includes a hollow frame 151 fixedly connected inside the first injection pipe 144, a connecting shaft 152 inserted at the axial center position of the hollow frame 151, and a limiting piece is provided at the top end of the connecting shaft 152.

[0051] Further, the blocking component 15 further includes a sealing plate 153 fixedly connected to the end of the connecting shaft 152, and the diameter of the sealing plate 153 matches the inner diameter of the first injection pipe 144, and a return spring 154 sleeved on the connecting shaft 152 and having both ends respectively abutted against the limiting piece of the connecting shaft 152 and the hollow frame 151. The return spring 154 jacks up the connecting shaft 152 upward through elastic support, thereby driving the sealing plate 153 to block the end of the first injection pipe 144, preventing the substances in the rotating drum 13 from entering the first injection pipe 144 upward. However, when the first injection pipe 144 injects liquid downward, the liquid will squeeze the top surface of the sealing plate 153, thereby compressing the return spring 154. At this time, the sealing plate 153 moves downward to open the first injection pipe 144, and the liquid can be normally transported into the rotating drum 13 through the first injection pipe 144. The blocking component 15 in the second injection pipe 145 is the same.

[0052] During use, when the stirring component 25 is driven by the driving component 23 to move to the end of the driving component 23, the second clamping seat 2522 at the end of the clamping component 252 will be clamped with the first clamping seat 131. At this time, the mounting seat 251 moves to the optical axis 232 and is no longer threadedly connected to the threaded shaft 231. At this time, the stirring component 254 no longer performs the stirring action, while the clamping component 252 connects the driving component 23 and the rotating drum 13 together. At this time, the driving component 23 drives the entire rotating drum 13 to perform high-speed centrifugal rotation. Under the action of centrifugal force, the emulsion after the raw material and the extractant are mixed and reacted will be centrifugally separated, and the substances obtained after separation and purification will be discharged from the first output groove 1421 and the second output groove 1431 respectively according to the actual situation. During the centrifugal separation process, the emulsion will be divided into a heavy phase 6 with a heavier mass, a light phase 4 with the lightest mass, and an emulsion 5 located between the two (such as Figure 7As shown, the heavy phase 6 is mainly located at the inner wall of the drum 13 and is guided by the second weir plate 143 to be discharged from the second output groove 1431. The light phase 4 is located at the axial center position of the drum 13 and is guided by the first weir plate 142 to be discharged from the first output groove 1421. The emulsion 5 is located between the heavy phase 6 and the light phase 4 and continues to perform centrifugation operations following the rotation of the drum 13.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
