Description

Technical Field

[0001] This utility model relates to the field of biological separation and processing, specifically a separation device for microbial extraction. Background Technology

[0002] In the field of microbial research and application, environmental microorganisms are diverse and numerous, with varying requirements for energy, nutrients, and physicochemical conditions, including differences in the types and concentrations of various factors. By appropriately optimizing existing culture media, it is possible to isolate and culture new microorganisms. Microbial isolation and culture technology plays a crucial role in the study of microbial environmental functions, the elucidation of metabolic pathways, the verification of specific functions, and applications in basic experiments and production practices; its importance is self-evident.

[0003] Solid-liquid separation is an essential step in the production of microbial inoculants. Currently, existing solid-liquid separation devices for microbial inoculant production mainly employ either compression or centrifugation for solid-liquid separation. However, when using centrifugation, the liquid passes directly through the mesh of the centrifuge tube and is discharged, while the solid remains inside. If too much solid accumulates and clogs the mesh, it will affect subsequent separation (as disclosed in patent application CN202321143289.3). Therefore, after a period of use, the centrifuge tube must be stopped, and workers must open the lid and remove the solid from inside the tube. Cleaning with water is then necessary, which is cumbersome and makes it difficult to completely remove the solid from the centrifuge tube. Utility Model Content

[0004] Therefore, to address the aforementioned shortcomings, this utility model provides a separation device for microbial extraction. This device employs a vertically placed and rotating separation cylinder to perform solid-liquid separation of the microbial extract. During rotation, the liquid passes through the mesh of the separation cylinder and falls into the separation tank, exiting through the discharge pipe. The solid remains inside the separation cylinder and rotates at high speed, achieving solid-liquid separation. Furthermore, the combination of the slag discharge pipe at the bottom of the separation cylinder and the internal water guide plate prevents the microbial extract discharged from the top feed pipe from being directly discharged through the slag discharge pipe. This facilitates centrifugal rotation of the microbial extract for separation and allows the solid to pass through the gap between the water guide plate and the inner wall of the separation cylinder under gravity when the separation cylinder stops, flowing into the slag discharge pipe and being discharged, thus simplifying the method of cleaning the separation cylinder.

[0005] This invention is achieved by providing a separation device for microbial extraction, including a separation tank that is kept vertical by a support column;

[0006] The separator is installed inside the separator tank and keeps rotating;

[0007] The feed pipe is located at the top of the separator tank and is connected to the center of the top of the separator cylinder.

[0008] The discharge pipe is located at the bottom of the separator and remains connected to the interior.

[0009] The slag discharge pipe is located at the bottom of the separator and is connected to the center of the bottom of the separator cylinder;

[0010] The water guide plate is located at the bottom center of the separator and maintains a gap with the inner wall of the separator.

[0011] Preferably, the two ends of the separation cylinder are tapered, the slag discharge pipe is fixed to the tapered end at the bottom of the separation cylinder, and a connecting cylinder is provided on the tapered end at the top of the separation cylinder. The connecting cylinder is kept in communication with the feed pipe and is rotatably connected through a first bearing.

[0012] Preferably, the top of the slag discharge pipe is connected to the bottom of the separation cylinder, the bottom of the slag discharge pipe extends to the outside of the separation tank, and a transmission wheel is provided on the slag discharge pipe outside the separation tank to drive the slag discharge pipe and the separation cylinder to rotate. The slag discharge pipe is rotatably connected to the separation tank through a second bearing.

[0013] Preferably, the water guide plate is shaped like a truncated cone, with its large end mounted on the center of the bottom of the separator via a support foot.

[0014] Preferably, the inner wall of the separator is provided with several drain holes for liquid discharge.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] First, the separation device uses a vertically placed and rotating separation cylinder to perform solid-liquid separation of microbial extract. This design allows the liquid to efficiently pass through the mesh of the separation cylinder during rotation, fall directly into the separation tank outside the separation cylinder, and be smoothly discharged from the discharge pipe, while the solid remains in the separation cylinder and rotates at high speed, thus achieving efficient solid-liquid separation.

[0017] Secondly, by combining the slag discharge pipe at the bottom of the separation cylinder with the internal water guide plate, the direct discharge of microbial extract from the top feed pipe through the slag discharge pipe is effectively prevented. This not only ensures that the microbial extract can fully undergo centrifugal rotation for separation, improving the separation effect and making the entire separation process more stable and reliable, but also allows the solids to smoothly pass through the gap between the water guide plate and the inner wall of the separation cylinder under gravity when the separation cylinder stops rotating, flowing into the slag discharge pipe and being discharged. This design simplifies the cleaning method of the separation cylinder, eliminating the need for frequent shutdowns for manual cleaning as required by existing centrifugal separators, greatly reducing the tediousness of cleaning work and improving the continuity and stability of production.

[0018] Finally, the separation device has an ingenious structural design, is easy to operate, and is easy to maintain and service. It can not only effectively solve the problems of residue and cleaning trouble in existing centrifugal separation devices, but also improve production efficiency and reduce production costs while ensuring solid-liquid separation effect.

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0028] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0029] As described in the background section, existing centrifugal separation devices are troublesome to clean because the solids inside the centrifuge tube are difficult to remove, which affects subsequent use and the quality and efficiency of separation.

[0030] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:

[0031] Example 1,

[0032] Please see the appendix Figure 1 ~Appendix Figure 6 A separation device for microbial extraction includes a separation tank 1, which is kept vertical by a support column 2;

[0033] Separation cylinder 7 is installed inside separation tank 1 and keeps rotating;

[0034] The feed pipe 3 is located at the top of the separator tank 1 and is connected to the center of the top of the separator cylinder 7;

[0035] The discharge pipe 4 is located at the bottom of the separator 1 and is in communication with the interior.

[0036] The slag discharge pipe 5 is located at the bottom of the separator 1 and is connected to the center of the bottom of the separator cylinder 7.

[0037] The water guide plate 11 is located at the bottom center of the separator 7 and maintains a gap with the inner wall of the separator 7.

[0038] In this embodiment, in order to achieve solid-liquid separation of the microbial extract, so as to facilitate the discharge of liquid from the discharge pipe and solid from the slag discharge pipe, the two ends of the separation cylinder 7 are conical. The slag discharge pipe 5 is fixed on the conical end at the bottom of the separation cylinder 7. A connecting cylinder 8 is provided on the conical end at the top of the separation cylinder 7. The connecting cylinder 8 is kept in communication with the feed pipe 3 and is rotated through the first bearing 9. Several drainage holes for liquid discharge are evenly opened on the inner wall of the separation cylinder 7.

[0039] Furthermore, the top of the slag discharge pipe 5 is connected to the bottom of the separation cylinder 7, and the bottom of the slag discharge pipe 5 extends to the outside of the separation tank 1. A transmission wheel 6 is provided on the slag discharge pipe 5 outside the separation tank 1 to drive the slag discharge pipe 5 and the separation cylinder 7 to rotate. The slag discharge pipe 5 is rotatably connected to the separation tank 7 through the second bearing 10.

[0040] During use, the transmission wheel 6 is pre-connected to an external drive motor and transmission belt. After connection, the drive motor drives the transmission wheel 6 to rotate, which in turn drives the separation cylinder 7 to rotate at high speed inside the separation tank 1. Then, microbial extract is added into the separation cylinder 7 through the feed pipe 3. After entering the separation cylinder 7, the microbial extract falls onto the water guide plate 11 and splashes, causing the microbial extract to splash onto the inner wall of the separation cylinder 7. Under the high-speed rotation of the separation cylinder 7, the microbial extract is simultaneously driven to undergo centrifugal motion. The liquid passes through the drain hole of the separation cylinder 7 and splashes onto the inner wall of the separation tank 1, and is finally discharged from the discharge pipe 4. The solids remain in the separation cylinder 7 and rotate at high speed. When cleaning is required, the rotation of the separation cylinder 7 is stopped. The solids lose centrifugal force and, under the action of gravity, pass through the gap between the water guide plate 11 and the inner wall of the separation cylinder 7 and fall into the slag discharge pipe 5 for final discharge. After discharge, water can be injected into the separation cylinder 7 through the feed pipe 3 for further cleaning, thus completing the cleaning process.

[0041] Example 2,

[0042] Please see the appendix Figure 6 Based on Example 1, in order to prevent the microbial extract discharged from the feed pipe from falling directly into the slag discharge pipe, thus preventing it from contacting the separation cylinder and affecting centrifugal separation, the water guide plate 11 is shaped like a truncated cone, and its large end bottom is installed at the center of the bottom of the separation cylinder 7 through the support foot 12.

[0043] As mentioned above, the support feet are provided to facilitate the installation of the water guide plate inside the separator cylinder, maintaining a gap between the plate and the bottom of the separator cylinder, thereby allowing solids to pass through the gap and be discharged from the separator cylinder.

[0044] Example 3,

[0045] Based on Embodiment 2, in order to ensure that the water guide plate can be installed inside the separator, the separator 7 can be configured as a splice type, that is, the conical end at the bottom of the separator and the cylindrical end of the separator are separate. After the water guide plate is installed in the conical end at the bottom of the separator, it can be fixed to the cylindrical end by welding.

[0046] Example 4,

[0047] Please see the appendix Figure 1 and attached Figure 3Based on Example 1, in order to prevent the microbial extract from being discharged directly from the slag discharge pipe, a plug is provided at the end of the slag discharge pipe 5. The plug is movably connected to the slag discharge pipe 5 by means of a threaded connection.

[0048] As mentioned above, the plug connection method on the slag discharge pipe, compared with the traditional valve, can ensure that the slag discharge pipe can rotate at high speed along the drive wheel, avoiding the loss of stability during rotation caused by the installation of traditional valves, which would affect the high-speed rotation of the internal separation cylinder.

[0049] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
