Description

Technical Field

[0001] This utility model relates to the field of bacterial activation technology, specifically to an aerobic bacteria activation reaction device. Background Technology

[0002] In order for aerobic bacteria strains to form colonies after cultivation, the usual practice is to place the bacterial powder into an activation reaction device, contact it with the nutrient solution, and strictly control the stability and aeration rate.

[0003] For example, Chinese utility model patent CN215799480U, entitled "An Activation Reaction Device for Aerobic Bacteria," includes a reaction vessel, a heater, a feed pipe, an aeration pipe, and a discharge pipe. The reaction vessel consists of an outer shell and an inner liner. The outer shell is hollow, and the inner liner is located inside the outer shell. The outer wall of the inner liner is sealed to the bottom of the outer shell, forming a water bath chamber between the inner liner and the outer shell. The heater is installed on the outer wall of the outer shell. A cover is provided at the top of the inner liner, and several aeration pipes and several feed pipes are installed on the cover. A discharge pipe is provided at the bottom of the inner liner. A water inlet and a water outlet are provided on the outer shell. Several support legs are installed at the bottom of the outer shell. This device heats the bacterial solution in the reaction vessel through a water bath heating method to better control the temperature of the bacterial solution and avoid the problem of bacterial death caused by localized heating. By combining the aeration pipe with the stirring rod, the stirring rod is powered by gas flow instead of motor drive, simplifying the stirring structure.

[0004] However, when using water bath heating, heating the inner tank through the outer shell is an indirect heating method, which has low heat transfer efficiency and may result in a slow rise in the temperature of the bacterial solution (especially in low-temperature environments). Furthermore, the water temperature control is not precise, which affects the activation rate of the bacterial community. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of low heat transfer efficiency affecting the activation rate of microbial communities when using water bath heating, this invention provides an aerobic bacteria activation reaction device. This device enables simultaneous heating of the material within the annular cavity by installing a first heating element 210 and a second heating element 220 on the circumferential sidewall and bottom inner wall of the annular cavity, respectively. This results in high heat transfer efficiency. Furthermore, at least one first stirring element 230 is installed within the annular cavity to continuously circulate the heating medium, further enhancing heat transfer efficiency and ensuring the activation rate of the microbial communities.

[0021] Please see Figure 1 Figure 2 , Figure 1This is a schematic diagram of the structure of an aerobic bacteria activation reaction device according to an embodiment of the present invention. The aerobic bacteria activation reaction device includes: a reaction vessel 100, a heating component 200, and an aeration component 300. The reaction vessel 100 is hollow inside and has a receiving cavity for receiving materials. The circumferential sidewall of the reaction vessel 100 has an annular cavity for temporarily storing the heating medium. The heating component 200 includes at least one first heating element 210, a second heating element 220, and at least one first stirring element 230. The first heating element 210 is disposed on the circumferential sidewall of the annular cavity and connected to the reaction vessel 100. The second heating element 220 is disposed on the bottom sidewall of the annular cavity and connected to the reaction vessel 100. The first stirring element 230 is rotatably housed within the annular cavity. The aeration component 300 is housed within the receiving cavity.

[0022] Compared with the prior art, this device, by setting a first heating element 210 and a second heating element 220 on the circumferential sidewall and bottom inner wall of the annular cavity respectively, can simultaneously heat the material in the cavity, resulting in high heat transfer efficiency. At the same time, at least one first stirring element 230 is also set in the annular cavity, which can drive the heating medium in the annular cavity to flow continuously, which helps to improve heat transfer efficiency and ensure the activation rate of bacteria. This solves the technical problem in the prior art where the heat transfer efficiency is low when using water bath heating, thus affecting the activation rate of bacteria.

[0023] Furthermore, the reactor 100 here is a commercially available and readily procurable reactor 100 structure with a jacketed heating chamber. Aerobic bacteria strains are introduced into the inner cavity of the reactor 100, and a heating medium, such as water, is introduced into the jacketed space to transfer the heat generated by the first heating element 210 and the second heating element 220.

[0024] Furthermore, the aeration component 300 here is a common and readily available aeration structure on the market, providing the necessary aerobic environment for the activation of aerobic bacteria. This can be seen in Chinese Utility Model Patent No. CN215799480U, entitled "An Activation Reaction Device for Aerobic Bacteria". The aeration component 300 here is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0025] In this embodiment, the first heating element 210 includes at least two first electric heaters, which are uniformly arranged along the circumferential sidewall of the annular cavity and are all connected to the reactor 100.

[0026] Multiple spaced first electric heaters are provided on the circumferential sidewall of the annular cavity to uniformly heat the heating medium and the material in the cavity.

[0027] Furthermore, the first electric heater here is elongated and set along the height of the reactor 100. The first electric heater is a common and readily available resistance heating element on the market, and it is waterproof. This can be found in Chinese Utility Model Patent with publication number CN215799480U, entitled "An Activation Reaction Device for Aerobic Bacteria". The first electric heater here is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0028] In some embodiments, the second heating element 220 includes at least two second electric heaters, which are disposed along the bottom of the annular cavity to uniformly heat the bottom of the cavity. The second electric heaters are conventional configurations known to those skilled in the art and will not be described in detail here.

[0029] In this embodiment, as Figure 1 As shown, the aerobic bacteria activation reaction device also includes a temperature detection unit 400, which is built into the receiving cavity and electrically connected to the first heating element 210 and the second heating element 220 respectively.

[0030] By setting a temperature detection unit 400 in the containment cavity to monitor the temperature, when the system is started or the ambient temperature is low, the first heating element 210 and the second heating element 220 can simultaneously heat the heating medium. When the temperature is higher than the preset value, the second heating element 220 stops heating, and the first heating element 210 continues to keep the material in the containment cavity warm.

[0031] Furthermore, the temperature detection unit 400 here is a common and readily available temperature sensor on the market, which is corrosion resistant. This is a common and readily available device on the market, and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0032] In one embodiment, as shown in the figure, the aerobic bacteria activation reaction device further includes a control component 500, which is connected to the reaction vessel 100 and electrically connected to the first heating element 210, the second heating element 220 and the temperature detection unit 400.

[0033] By setting the control component 500 to be electrically connected to the first heating element 210, the second heating element 220 and the temperature detection unit 400, the heating component 200 can be automatically controlled. The first heating element 210 and the second heating element 220 can be automatically and intelligently controlled according to the temperature change detected by the temperature detection unit 400.

[0034] Furthermore, the control component 500 here is a common and readily available device on the market. The control component 500 includes a PLC controller, a driver, and a controller. This is a conventional setup known to those skilled in the art and will not be described in detail here.

[0035] In this embodiment, as shown in the figure, the first stirring element 230 includes a first stirring blade 231 and a first rotating shaft 232. The first stirring blade 231 is built into an annular cavity, and the first rotating shaft 232 is arranged along the height direction of the annular cavity. One end of the first rotating shaft 232 is connected to the first stirring blade 231, and the other end is rotatably connected to the reactor 100.

[0036] Driven by the first rotating shaft 232, the first stirring blade 231 can rotate relative to the inner wall of the annular cavity, thereby stirring the heating medium inside the annular cavity.

[0037] Furthermore, the first stirring blade 231 here is a common and readily available stirring paddle structure on the market, arranged in a spiral shape and with corrosion resistance. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0038] In this embodiment, as shown in the figure, the other end of the first rotating shaft 232 is externally placed in the reactor 100. The heating assembly 200 also includes at least one driving component 240. The driving component 240 includes a first gear 241, a second gear 242, and a driving motor 243. The first gear 241 is rotatably connected to the reactor 100, and the second gear 242 is sleeved on the other end of the first rotating shaft 232. The fixed end of the driving motor 243 is connected to the reactor 100, and the output shaft is connected to the first gear 241, which is used to drive the first rotating shaft 232 and the first stirring blade 231 to rotate relative to the annular cavity.

[0039] The first stirring blade 231 and the first rotating shaft 232 are driven by a drive motor 243, and the meshing of the first gear 241 and the second gear 242 is used to transmit motion.

[0040] Furthermore, by setting a transmission ratio of a certain proportion, the stirring rate can be adjusted according to specific circumstances. Here, a reasonable selection needs to be made based on the specific circumstances, which will not be elaborated further.

[0041] In one embodiment, such as Figure 4 As shown, the aerobic bacteria activation reaction device also includes a stirring assembly 500. The stirring assembly 500 includes at least one second stirring element 510. The second stirring element 510 includes a second stirring blade 511 and a second rotating shaft 512. The second stirring blade 511 is built into the receiving cavity and is spaced apart from the aeration assembly 300. The second rotating shaft 512 is arranged along the axial direction of the reaction vessel 100, and one end of the second rotating shaft 512 is connected to the second stirring blade 511, and the other end is rotatably connected to the reaction vessel 100.

[0042] By installing a second stirring element 510 inside the containment cavity, the efficiency of heat transfer can be improved, allowing the material inside the containment cavity to be heated evenly.

[0043] Further, the second stirring blade 511 here is a commonly commercially available and easily purchasable stirring impeller structure, arranged in a spiral shape and having corrosion resistance, which is a conventional arrangement well known to those skilled in the art, and will not be elaborated herein.

[0044] In one embodiment, as shown in Figure 1 , Figure 2 the other end of the second rotating shaft 512 is disposed outside the reaction kettle 100. The stirring assembly 500 further includes at least one transmission member 520. The transmission member 520 includes a third gear 521, a transmission gear 522 and a linear driving portion 523. The third gear 521 is sleeved on the other end of the second rotating shaft 512. The transmission gear 522 is disposed between the first gear 241 and the third gear 521 and can rotate relative to the reaction kettle 100. The linear driving portion 523 has a fixed end and a telescopic end. The fixed end of the linear driving portion 523 is connected to the reaction kettle 100, and the telescopic end is connected to the third gear 521, for driving the transmission gear 522 to slide relative to the first gear 241 and the third gear 521, to mesh with the first gear 241 and the third gear 521 at the same time, and the linear driving portion 523 is electrically connected to the control assembly 500.

[0045] The transmission member 520 is disposed between the second rotating shaft 512 and the first rotating shaft 232, which can realize motion transmission, thereby reducing the number of driving motors 243 and simplifying the structure.

[0046] Further, here the linear driving portion 523 is used to drive the transmission gear 522 to slide relative to the first gear 241 and the third gear 521, so that the accommodating cavity can be stirred according to different use scenarios. When the reaction has proceeded for a period of time and the stirring resistance in the reaction kettle 100 is high, the rotation of the second stirring blade 511 relative to the reaction kettle 100 can provide additional torque, and the rotation of the stirring blade generates a vortex to enhance the circulation of the bacterial liquid; when the stirring resistance in the reaction kettle 100 is normal, the second stirring blade 511 is not connected to the transmission member 520.

[0047] In addition, in some embodiments, as shown in Figure 3 , the transmission member 520 further includes a bracket 524. The bracket 524 is in a "C" shape. The third gear 521 is rotatably embedded in the bracket 524, and the bracket 524 is connected to the telescopic end of the linear driving portion 523, which can realize the sliding of the transmission gear 522 relative to the first gear 241 and the third gear 521, and at the same time, the transmission gear 522 can also mesh with the first gear 241 and the third gear 521.

[0048] Further, the linear driving portion 523 here is a small-sized push rod motor that is commonly available on the market and easy to purchase, which is a conventional arrangement well known to those skilled in the art, and will not be elaborated herein.

[0049] In one embodiment, such as Figure 1 , Figure 2 As shown, the heating assembly 200 has two first stirring elements 230, and the two first stirring blades 231 are spaced apart along the extension direction of the annular cavity. The stirring assembly 500 has two second stirring elements 510, and the two second stirring blades 511 are spaced apart along the circumference of the aeration assembly 300. The transmission gear 522 and the third gear 521 are arranged in a one-to-one correspondence and can mesh with the third gear 521 and the first gear 241 at the same time.

[0050] To improve heat transfer efficiency, there are two of each of the first stirring element 230 and the second stirring element 510, and the transmission element 520 is set in a one-to-one correspondence with the second stirring element 510.

[0051] In one embodiment, such as Figure 1 As shown, the aerobic bacteria activation reaction device also includes a pressure detection unit 600, which is built into the receiving cavity and connected to the reaction vessel 100. The pressure detection unit 600 is electrically connected to the control component 500 and the linear drive unit 523.

[0052] By electrically connecting the pressure detection unit 600 to the control component 500 and the linear drive unit 523, automated and intelligent control of the second stirring component 510 can be achieved.

[0053] Furthermore, the pressure detection unit 600 here is a common and readily available pressure sensor on the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0054] In addition, in some implementations, in order to avoid the transmission between gears being affected by the environment or dust, this application also includes a dust cover. The dust cover is installed on the first gear 241, the second gear 242, the transmission gear 522 and the third gear 521. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0055] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: The reactor 100 has a receiving cavity for containing materials, and an annular cavity for containing heating medium is also formed on the circumferential sidewall of the reactor 100. A first heating element 210 is disposed on the circumferential sidewall of the annular cavity, a second heating element 220 is disposed on the bottom sidewall of the annular cavity, and a first stirring element 230 is rotatably built into the annular cavity. An aeration assembly 300 is built into the receiving cavity. Compared with the prior art, by respectively arranging the first heating element 210 and the second heating element 220 on the circumferential sidewall and the bottom inner wall of the annular cavity, the materials in the receiving cavity can be heated simultaneously, resulting in high heat transfer efficiency. At the same time, the presence of at least one first stirring element 230 in the annular cavity can continuously drive the heating medium in the annular cavity to flow, which helps to improve heat transfer efficiency and ensure the activation rate of the microbial community. This solves the technical problem in the prior art where the low heat transfer efficiency when using water bath heating affects the activation rate of the microbial community.

[0056] The specific working process of this utility model is as follows: After the device is started, the heating system begins to work; the first heating element 210 (multiple first electric heaters) located on the circumferential annular cavity sidewall of the reactor 100 and the second heating element 220 (second electric heater) located at the bottom of the cavity are activated simultaneously to heat the heating medium such as water in the annular cavity. The heat is evenly transferred to the internal containment cavity through the jacketed structure, causing the temperature of the bacterial solution to rise; A temperature detection unit 400 (temperature sensor) built into the containment cavity monitors the temperature of the bacterial solution in real time and transmits the data to a control component 500 (such as a PLC controller). The control component 500 compares the measured temperature with a set value (e.g., 20-35℃, suitable for the activation of aerobic bacteria) and automatically adjusts the operating status of the heating elements. For example, during startup or in low-temperature environments, the first heating element 210 and the second heating element 220 can work simultaneously at full capacity to rapidly raise the temperature; when the temperature approaches or reaches the set value, the second heating element 220 stops working, and only the first heating element 210 maintains the temperature to ensure temperature stability and prevent local overheating from damaging the bacteria.

[0057] Furthermore, at the same time as heating begins, the aeration component 300 is activated, injecting air into the bacterial solution in the containment chamber in the form of tiny bubbles; this not only provides the necessary oxygen for the metabolism and activation of aerobic bacteria, but the rising movement of the bubbles also initially plays a role in stirring the bacterial solution.

[0058] Furthermore, the first stirring element 230 (first stirring blade 231 and first rotating shaft 232) located in the annular cavity rotates slowly under the drive of the drive motor 243, stirring the heating medium (such as water), which can effectively break the temperature stratification in the water bath medium and promote the heat to be transferred to the bacterial liquid more quickly and evenly through the vessel wall.

[0059] Furthermore, the second stirring element 510 (second stirring blade 511 and second rotating shaft 512) located in the containment cavity directly mechanically stirs the bacterial solution. It is linked to the drive system of the first stirring element 230 through a disengageable transmission element 520 (such as a gear set). When the control component 500 determines that it is necessary to enhance stirring based on the pressure sensor signal or a preset program (such as when the bacterial solution has high viscosity), the linear drive unit 523 will be activated, causing the transmission gear 522 to simultaneously mesh with the first gear 241 and the third gear 521, thereby transmitting power from the heating medium stirring system to the bacterial solution stirring system, making them rotate synchronously.

[0060] This application, through the aforementioned structure, solves the technical problem in the prior art where low heat transfer efficiency during water bath heating affects the activation rate of bacterial communities. The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
