Technical Field
[0001] This utility model relates to the field of separation technology, and in particular to a device for solid-liquid separation and collection of fungal fermentation broth. Background Technology
[0002] In laboratory experiments on fungi, the fungi are first cultured and fermented, and then the fermented mixture is separated into solid and liquid components. The liquid is then extracted for subsequent experiments or component analysis.
[0003] A search revealed a Chinese patent publication number CN222287595U, which discloses a centrifugal compound solid-liquid separation device. The device includes a separation body with an upper feeding plate, multiple solid-liquid separation cylinders connected to the feeding plate via connecting pipes, and centrifugal separation components located within each solid-liquid separation cylinder. The feeding plate distributes the compound solution to be separated into equal amounts within the centrifugal cylinders for batch centrifugal solid-liquid separation, facilitating the simultaneous processing of large quantities of compound solutions. Furthermore, the inner walls of the centrifugal cylinders are coated with a corrosion-resistant material, enabling them to withstand centrifugal force at high speeds and potentially corrosive liquids.
[0004] The above-mentioned patent has the following shortcomings: it cannot dry the separated solids. Since some fungi will still remain in the separated solids, if the solids are not dried, the fungi carried by the solids may ferment and multiply again, resulting in fungal contamination.
[0005] To address this, a device for solid-liquid separation and collection of fungal fermentation broth is proposed. Utility Model Content

The rotating centrifuge chamber is rotatably connected to the inner wall of the shell via a rotating shaft, and the top of the shell and the rotating centrifuge chamber are fitted with a shell cover. The bottom outer wall of the shell is fixed with a motor by bolts, and the output shaft of the motor is connected to the end of the rotating shaft via a coupling. The inner wall of the rotating centrifuge chamber is fixedly embedded with a heating wire.
[0007] In some embodiments, the top inner wall of the rotating centrifuge chamber is provided with a plurality of concentric grooves, and the bottom of the shell cover is rotatably connected with a plurality of sealing rings that cooperate with the grooves.
[0008] In some embodiments, the cross-section of the groove and the sealing ring is a trapezoid with a smaller bottom and a larger top.
[0009] In some embodiments, a cavity shell is fixed to the inner wall of the outer shell, an electrode plate is fixed to the inner wall of the cavity shell, and an elastic electrode head electrically connected to the heating wire is fixed to the bottom of the rotating centrifugal cavity.

[0010] In some embodiments, the opening of the cavity shell is rotatably sealed with an end cap, and the exposed portion of the elastic electrode head located between the rotating centrifuge chamber and the end cap is covered with an insulating layer.
[0011] In some embodiments, the elastic electrode head includes a fixed column fixed to the outer wall of the bottom of the rotating centrifuge chamber and an elastic column slidably connected to the inner wall of the bottom of the fixed column. The end of the elastic column is provided with a ball bearing that rolls against the outer wall of the electrode sheet. A spring is fastened to the opposite side of the elastic column and the fixed column.
[0012] In some embodiments, a drain hole is provided on the bottom inner wall of the housing, and a drain pipe is fixed on the outer wall of the housing at the drain hole, so that the separated liquid can be discharged through the drain hole and the drain pipe.

[0014] In some embodiments, the longitudinal portion of the drain pipe is fixed with a fixing ring and slidably connected with a pressure ring, and the end of the drain pipe is fixed with a protrusion. The pressure ring and the fixing ring are fastened to the opposite side by the same spring.
[0015] The present invention has the following advantages due to the adoption of the above technical solution:

On the one hand, the liquid is removed to prevent further fermentation of fungi, and on the other hand, the high temperature can also extinguish the fungi remaining on the solid, thereby preventing fungal contamination.
[0017] 2. A device for solid-liquid separation and collection of fungal fermentation broth, wherein a groove and a sealing ring are provided, which work together to seal the inside of the rotating centrifuge chamber, thereby preventing incomplete separation caused by solid leakage from the top of the rotating centrifuge chamber during high-speed centrifugation.

Detailed Implementation
[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0030] Example 1: As Figures 1-5As shown, a device for solid-liquid separation and collection of fungal fermentation broth includes a shell 1 and a rotary centrifuge chamber 2. The rotary centrifuge chamber 2 is rotatably connected to the inner wall of the shell 1 via a rotating shaft 4. The top of the shell 1 and the rotary centrifuge chamber 2 are fitted together with a cover 3. The bottom outer wall of the shell 1 is fixed with a motor 5 by bolts. The output shaft of the motor 5 is connected to the end of the rotating shaft 4 via a coupling.
[0031] The cover 3 is fixedly fitted to the outer shell 1. In this embodiment, the fixing method is not limited. It can be fixed by bolts, buckles, threads, etc. It is only necessary to make the cover 3 fixed and detachable relative to the outer shell 1. All of the above are existing technologies.
[0032] A heating wire 8 is fixedly embedded in the inner wall of the rotating centrifuge chamber 2.
[0033] The top inner wall of the rotating centrifuge chamber 2 is provided with multiple concentric grooves 6, and the bottom of the cover 3 is rotatably connected with multiple sealing rings 7 that cooperate with the grooves 6.
[0034] The cross-sections of the groove 6 and the sealing ring 7 are trapezoidal, with the bottom being smaller and the top being larger.
[0035] When using this device, the fermentation liquid can be poured into the centrifuge chamber 2, and then the cover 3 can be fixed to the outer shell 1. At this time, the groove 6 and the sealing ring 7 cooperate to seal. Then, the motor 5 is started. The motor 5 drives the centrifuge chamber 2 to rotate at high speed through the rotating shaft 4, so that the liquid that is fixed inside the centrifuge chamber 2 and is subjected to centrifugal force enters the inner cavity of the outer shell 1 through the micropores, thus achieving separation. After separation, the heating wire 8 inside the centrifuge chamber 2 is energized to dry the residual solid at high temperature.
[0036] This device, by setting up an electric heating wire 8, can dry the separated solids at high temperature. On the one hand, it removes the liquid to prevent further fermentation of fungi, and on the other hand, the high temperature can also extinguish the fungi remaining on the solids, thereby preventing fungal contamination.
[0037] In addition, by setting the groove 6 and the sealing ring 7, the device can seal the inside of the rotating centrifuge chamber 2, thereby preventing the solid from leaking out from the top of the rotating centrifuge chamber 2 during high-speed centrifugation and causing incomplete separation.
[0038] In this embodiment, a cavity shell 10 is fixed to the inner wall of the outer shell 1, and an electrode plate 11 is fixed to the inner wall of the cavity shell 10. An elastic electrode head 23 electrically connected to the heating wire 8 is fixed to the bottom of the rotating centrifugal cavity 2. The elastic electrode head 23 is in contact with and electrically connected to the top of the electrode plate 11.
[0039] The opening of the cavity shell 10 is sealed with a rotating end cap 9, and the exposed portion of the elastic electrode head 23 located between the rotating centrifugal cavity 2 and the end cap 9 is covered with insulating skin.
[0040] Since the rotating centrifugal chamber 2 drives the heating wire 8 to rotate at high speed, it also makes it difficult to connect the power supply wire of the heating wire 8. This device, by setting up the elastic electrode head 23 and the electrode plate 11, can reliably supply power while the heating wire 8 rotates at high speed. At the same time, by setting up the end cover 9 and the insulating skin, it can seal the contact point between the electrode plate 11 and the elastic electrode head 23 on the one hand, and insulate the exposed part of the elastic electrode head 23 on the other hand, thereby increasing safety.
[0041] In this embodiment, the elastic electrode head 23 includes a fixed column 12 fixed to the bottom outer wall of the rotating centrifuge chamber 2 and an elastic column 13 slidably connected to the bottom inner wall of the fixed column 12. The end of the elastic column 13 is provided with a ball bearing 15 that rolls against the outer wall of the electrode sheet 11. A spring 14 is fastened to the opposite side of the elastic column 13 and the fixed column 12.
[0042] The electrode plate 11 can be connected to an external power supply with a switch. Then, the electrode plate 11 contacts the copper drum of the ball bearing 15 to achieve conductivity. Subsequently, a wire can be led out through the elastic post 13 and connected to the heating wire 8 to complete the power supply of the heating wire 8.
[0043] This device, by setting the elastic electrode head 23 as a combination of fixed post 12, elastic post 13 and ball 15, can reduce friction loss by utilizing the rolling friction of ball 15, and can provide elastic compensation for friction by the elastic force of spring 14, thus ensuring the reliability of contact between ball 15 and electrode plate 11.
[0044] In this embodiment, a drain hole 16 is provided on the bottom inner wall of the outer shell 1, and a drain pipe 17 is fixed on the outer wall of the outer shell 1 at the drain hole 16. The separated liquid can be discharged through the drain hole 16 and the drain pipe 17.
[0045] In this embodiment: When using this device, the fermentation liquid can be poured into the rotating centrifuge chamber 2, and then the shell cover 3 is fixed to the outer shell 1. At this time, the groove 6 and the sealing ring 7 cooperate to seal. Then, the motor 5 is started. The motor 5 drives the rotating centrifuge chamber 2 to rotate at high speed through the rotating shaft 4, so that the liquid that is fixed inside the rotating centrifuge chamber 2 is separated by the centrifugal force through the micropores. After separation, the heating wire 8 inside the rotating centrifuge chamber 2 is energized to dry the residual solid at high temperature. After drying, it can be scooped out, and the separated liquid can be discharged through the drain hole 16 and the drain pipe 17.
[0046] Example 2: A device for solid-liquid separation and collection of fungal fermentation broth. This example is based on Example 1 with the following improvements, such as... Figure 5 As shown, a valve 22 is installed on the drain pipe 17.
[0047] In this embodiment, the longitudinal portion of the drain pipe 17 is fixed with a fixing ring 21 and slidably connected with a pressure ring 19. The end of the drain pipe 17 is fixed with a protrusion 18. The pressure ring 19 and the fixing ring 21 are fastened with the same spring 20 on opposite sides.
[0048] In this embodiment: During centrifugation, valve 22 can be closed, and the liquid can be stored in the outer shell 1. When collecting, the opening of the collecting bag can be placed between the protrusion 18 and the pressure ring 19, and the bag opening can be fixed by the elastic force of spring 20. Then, the drain pipe 17 can be opened to collect the liquid.
[0049] This device, by setting valve 22, can temporarily store liquid, allowing for multiple fillings and collections in edible containers. At the same time, by setting components such as protrusion 18, pressure ring 19, spring 20, and fixing ring 21, it can fix the bag during collection, increasing the convenience of use.
