Specific implementation

[0028] In order to make the person in the technical field better understand the technical scheme in the utility model, the technical scheme in the embodiment of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiment of the utility model, obviously, the described embodiment only is a part of the embodiment of the utility model, and is not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor should belong to the protection scope of the utility model.

[0029] As Figures 1-3 The utility model discloses an embodiment of a kind of bioreactors, including reaction tank 1, reaction tank 1 top is equipped with motor 2, and the output end of motor 2 is equipped with stirring rod 201. Raw material is sent into reaction tank 1 from feed inlet, and motor 2 is started, and motor 2 drives stirring rod 201 rotation and mixes uniformly in reaction tank 1 reaction liquid. Collecting mechanism is installed in reaction tank 1, and the foam accumulated on the surface of reaction liquid is collected by collecting mechanism, as far as possible avoid foam accumulation on the surface of reaction liquid, make gas transmission be blocked, cause the oxygen required by microorganism to be difficult to enter reaction liquid, influence the growth and metabolism of microorganism in reaction liquid, make the reaction efficiency reduce.

[0030] As Figures 2-3As shown, the collecting mechanism comprises a first collecting plate 301 which is slidingly mounted outside the stirring rod 201, a plurality of breaking needles 3011 are mounted on the side of the first collecting plate 301 close to the foam, and a second collecting plate 302 is mounted at one end of the first collecting plate 301. During the rotation of the first collecting plate 301 with the stirring rod 201, the breaking needles 3011 on the first collecting plate 301 break the sparse large bubbles, and the bubbles that cannot be broken by the breaking needles 3011 are gathered on the second collecting plate 302 along the first collecting plate 301 during the rotation of the first collecting plate 301, so that the foam is separated from the surface of the reaction liquid and is prevented from accumulating on the surface of the reaction liquid to form a barrier as much as possible.

[0031] As shown in the drawings, Figure 3 The collecting mechanism further comprises an annular float 303 for supporting the first collecting plate 301. Since the annular float 303 is always floating on the surface of the reaction liquid and the first collecting plate 301 is sliding on the upper part of the annular float 303, the first collecting plate 301 can collect the foam accumulated on the surface of the reaction liquid at different liquid levels, thereby expanding the application range of the collecting mechanism to a certain extent.

[0032] The model of the motor 2 can be Y80M1-2, and users can also select different models according to actual market demand. The motor 2 is electrically connected with an external power supply, and since the motor 2 is a common knowledge in the art, the specific structure, switching mode and working principle are not described in detail here.

[0033] As shown in the drawings, Figure 3 The second collecting plate 302 is provided with a third collecting plate 305 above for static defoaming, the reaction tank 1 is provided with a supporting assembly for supporting the third collecting plate 305, and the reaction tank 1 is provided with a limiting component for limiting the position of the third collecting plate 305. When the second collecting plate 302 rotates and the edge of the second collecting plate 302 at the connection with the first collecting plate 301 contacts the edge of the third collecting plate 305, the second collecting plate 302 continues to rotate until the edge of the third collecting plate 305 gradually scrapes off the foam accumulated on the second collecting plate 302, so that the foam stays on the third collecting plate 305 and is gradually broken to complete defoaming after a period of static state.

[0034] For example, when the second collecting plate 302 rotates clockwise and the edge of the second collecting plate 302 at the connection with the first collecting plate 301 contacts the edge of the third collecting plate 305, the second collecting plate 302 continues to rotate until the second collecting plate 302 gradually rotates to the bottom of the third collecting plate 305 and gradually coincides with the third collecting plate 305. In this process, the foam on the second collecting plate 302 is scraped off by the edge of the third collecting plate 305, and finally the foam stays on the third collecting plate 305 for static defoaming.

[0035] As shown in the drawings, Figure 3As shown, the support assembly can be a support rod 304 connected to the bottom of the third collecting plate 305 in a sliding manner, and the support rod 304 is fixedly connected to the second collecting plate 302. The support rod 304 supports the third collecting plate 305 while limiting the height of the third collecting plate 305, so that the third collecting plate 305 is close to the support rod 304, and the situation that the third collecting plate 305 slides over the second collecting plate 302 and cannot scrape the foam accumulated on the second collecting plate 302 is avoided as much as possible.

[0036] As shown in the Figure 5 As shown, the limiting component includes a limiting sliding groove 306 matched with the third collecting plate 305, and the limiting sliding groove 306 is arranged on the inner wall of the reaction tank 1. The limiting component prevents the third collecting plate 305 from rotating as much as possible, so that the foam on the second collecting plate 302 is smoothly transferred to the third collecting plate 305.

[0037] As shown in the Figure 5 As shown, a flow guide groove 307 is arranged on the upper surface of the third collecting plate 305, and a liquid discharge hole 3071 is arranged at one end of the flow guide groove 307 close to the inner wall of the reaction tank 1. The reaction liquid left after the foam is broken slides along the flow guide groove 307 and the liquid discharge hole 3071 and drops back into the reaction tank 1. To some extent, the change of the concentration of the reaction liquid is avoided, and the growth of microorganisms and the normal progress of the reaction are affected.

[0038] As shown in the Figure 7 As shown, the third collecting plate 305 is provided with a limiting baffle 3051 for limiting the foam area. The limiting baffle 3051 can avoid the foam from falling back to the surface of the reaction liquid from the edge of the third collecting plate 305 as much as possible.

[0039] As shown in the Figures 1-6 As shown, the reaction tank 1 is provided with an adsorption mechanism for controlling the starting of the collecting mechanism.

[0040] As shown in the Figures 1-6 As shown, the adsorption mechanism includes a first magnet 101 which is detachably installed on the reaction tank 1, and the annular float 303 is provided with a second magnet 3031 matched with the first magnet 101. When the foam accumulated on the surface of the reaction liquid affects the reaction, the first magnet 101 is pulled away upward, the first magnet 101 is away from the second magnet 3031, and then the second magnet 3031 loses the suction force, so that the annular float 303 falls to the surface of the reaction liquid to collect the foam.

[0041] As shown in the Figure 2 As shown, the reaction tank 1 is provided with a visual window 102. The staff can observe the foam on the surface of the reaction liquid in the reaction tank 1 at any time through the visual window 102, so as to control the adsorption mechanism

[0042] During use, when the foam accumulated on the surface of the reaction liquid hinders the effective contact and mass transfer between the reaction liquid and the gas, the collecting mechanism is placed on the surface of the reaction liquid, the motor 2 of the bioreactor drives the collecting mechanism to rotate, the foam accumulated on the surface of the reaction liquid is collected on the third collecting plate 305 away from the surface of the reaction liquid, and the foam is settled to avoid the foam from affecting the normal reaction of the microorganisms in the bioreactor as much as possible.

[0043] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
