Description

Technical Field

[0001] This utility model belongs to the field of fermentation equipment technology, and specifically relates to a liquid-solid two-phase fermenter equipped with a uniform heating structure. Background Technology

[0002] A liquid-solid two-phase fermenter is a bioreactor that integrates liquid and solid-state fermentation functions, primarily used for the large-scale production of microbial preparations (such as fungicides and insecticides) or biofuels (such as straw ethanol). However, existing liquid-solid two-phase fermenters still have drawbacks. In the solid-state fermentation unit, due to differences in material bulk density (e.g., the bottom layer of straw is more compacted than the surface layer) and low thermal conductivity, it is difficult for a single-sided heating plate or bottom heat source to penetrate the material layer. Furthermore, high-viscosity fermentation broth (such as enzymatic hydrolysis mash containing 10% cellulose) forms localized overheating zones and low-temperature dead zones due to poor fluidity. This not only causes metabolic disorders in the microorganisms but also damages the agitator sealing structure due to thermal stress. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a liquid-solid two-phase fermenter with a uniform heating structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a liquid-solid two-phase fermenter with a uniform heating structure, comprising: a transmission assembly and a gear ring, wherein the transmission assembly is installed on the top surface of the top cover of the device housing, and the transmission assembly includes a driving wheel and a driven wheel for transmission;

[0005] The driving wheel and the driven wheel are driven by a belt. A stirring shaft for stirring is installed below the driving wheel. A gear is installed below the driven wheel via a transmission shaft. The gear meshes with the inner side of a gear ring installed on the lower surface of the top cover. An electric heating wire is installed below the gear ring.

[0006] In a preferred embodiment, the device housing has an inner liner inside, and a rotating cavity is formed between the inner liner and the device housing. A cold air pipe is provided through the bottom left side of the rotating cavity, and an exhaust pipe is provided through the bottom right side of the rotating cavity.

[0007] In a preferred embodiment, the heating wire has a spiral structure, is located inside the rotating cavity, and the top of the heating wire is connected and fixed to the lower surface of the gear ring via two sets of connecting rods.

[0008] In a preferred embodiment, the gear ring is installed inside a placement cavity opened on the lower surface of the top cover, and a motor is installed on the top. The lower output end of the motor is connected to the top of the drive wheel through a coupling.

[0009] In a preferred embodiment, the driving wheel and the driven wheel have the same specifications, and a protective shell is installed on the outside of the driving wheel and the driven wheel.

[0010] In a preferred embodiment, the top of the stirring shaft is connected to the bottom of the drive wheel, the stirring shaft extends downward into the inner liner, and a stirring component is installed at the upper and lower positions of the part of the stirring shaft inside the inner liner.

[0011] In a preferred embodiment, the stirring assembly includes four sets of stirring blades of the same specifications and a fixing sleeve. Each set of stirring blades is inclined at a 30-degree angle, and the inner side of the fixing sleeve is sleeved and fixed to the outer side of the stirring shaft.

[0012] In a preferred embodiment, a feed pipe is provided through the front side of the top cover, a liquid discharge pipe is provided through the front side of the lower part of the device housing, and a solid discharge pipe is provided through the bottom of the device housing.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up a transmission component, a gear ring, and an electric heating wire, in actual use, the motor drives the drive wheel to rotate, the drive wheel drives the driven wheel to rotate through the belt, and thus the driven wheel drives the gear below it to rotate, the gear rotation drives the gear ring to rotate, so the rotation of the gear ring can drive the spiral structure electric heating wire to rotate inside the rotating cavity. The inner liner adopts a single-layer structure design, which is more conducive to heat transfer. The electric heating wire rotates at a uniform speed and continuously inside the rotating cavity, thus significantly improving the heating uniformity inside the inner liner.

[0014] 2. By setting up a stirring shaft and stirring components, in actual use, the stirring shaft rotates inside the inner tank under the drive of the drive wheel, thereby driving the two sets of stirring components to rotate. The stirring components consist of four sets of stirring blades of the same specifications at a 30-degree angle and a fixing sleeve for fixing. Therefore, the stirring blades can stir the liquid on the one hand, and the angle design is more conducive to cutting into the interior of the fixed material, thus facilitating the stirring of the fixed material. Therefore, by setting up the stirring components and stirring shaft, the liquid and solid materials can be stirred better, so that the liquid and solid materials are heated evenly, which helps to increase the uniformity of heating.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As the first embodiment of this utility model: a liquid-solid two-phase fermenter with a uniform heating structure, including: a transmission assembly 200 and a gear ring 300. The transmission assembly 200 is installed on the upper surface of the top cover 110 on the top of the device housing 100. The transmission assembly 200 includes a driving wheel 210 and a driven wheel 220 for transmission.

[0025] The driving wheel 210 and the driven wheel 220 are driven by a belt 230. A stirring shaft 211 for stirring is installed below the driving wheel 210. A gear 222 is installed below the driven wheel 220 via a drive shaft 221. The gear 222 meshes with the inner side of the gear ring 300 installed on the lower surface of the top cover 110. An electric heating wire 310 is installed below the gear ring 300.

[0026] An inner liner 130 is provided inside the outer casing 100 of the device. A rotating cavity 140 is formed between the inner liner 130 and the outer casing 100 of the device. A cold air pipe is provided through the bottom left side of the rotating cavity 140, and an exhaust pipe is provided through the bottom right side of the rotating cavity 140.

[0027] The electric heating wire 310 has a spiral structure and is located inside the rotating cavity 140. The top of the electric heating wire 310 is connected and fixed to the lower surface of the gear ring 300 through two sets of connecting rods.

[0028] The gear ring 300 is installed inside the placement cavity opened on the lower surface of the top cover 110, and a motor 120 is installed on the top. The output end of the motor 120 is connected to the top of the drive wheel 210 through a coupling.

[0029] The driving wheel 210 and the driven wheel 220 have the same specifications, and a protective shell is installed on the outside of the driving wheel 210 and the driven wheel 220.

[0030] A feed pipe is provided through the front side of the top cover 110, a liquid discharge pipe is provided through the front side of the lower part of the device housing 100, and a solid discharge pipe is provided through the bottom of the device housing 100.

[0031] In actual use, the raw material enters the inner liner 130 through the feed pipe. The feed pipe adopts a large-diameter tubular structure, allowing both liquid and solid raw materials to enter. At this time, the motor 120 is started (motor 120 is existing technology, and its model can be selected according to the models available on the market, which will not be described in detail). The motor 120 intermittently drives the drive wheel 210 in the transmission assembly 200 to rotate. The drive wheel 210 drives the driven wheel 220 to rotate through the belt 230. After the driven wheel 220 rotates, it drives the gear 222 to rotate through the transmission shaft 221 below. The outer side of the gear 222 is connected to the top. The gear ring 300 installed below the cover 110 engages, thus driving the gear ring 300 to rotate. After the gear ring 300 rotates, it drives the spiral electric heating wire 310 to rotate at a uniform and slow speed inside the rotating cavity 140 through a pair of connecting rods (a battery is built into the lower surface of the gear ring 300, and the electric heating wire is heated through the wires embedded in the two sets of connecting rods). The inner liner 130 adopts a single-layer structure design, which is more conducive to heat transfer. Through the uniform and continuous rotation of the electric heating wire 310 inside the rotating cavity 140, the heating uniformity inside the inner liner 130 can be significantly improved.

[0032] Please see Figures 1-4 As a second embodiment of the present invention: based on the description in the above embodiments, further, the top of the stirring shaft 211 is connected to the bottom of the drive wheel 210, the stirring shaft 211 extends downward into the inner liner 130, and a stirring component is installed at the upper and lower positions of the part of the stirring shaft 211 inside the inner liner 130.

[0033] The stirring assembly includes four sets of identical stirring blades 212 and a fixed sleeve. Each set of stirring blades 212 is inclined at a 30-degree angle, and the inner side of the fixed sleeve is fitted and fixed to the outer side of the stirring shaft 211.

[0034] In actual use, when the motor 120 drives the drive wheel 210 to rotate, the transmission component 200 drives the gear ring 300 to drive the electric heating wire 310 to rotate slowly and uniformly. This can improve the uniformity of heating and is beneficial to fermentation. This process is described in detail in Example 1 and will not be repeated here. When the drive wheel 210 rotates, the stirring shaft 211 below it rotates inside the inner liner 130. A pair of stirring components at the upper and lower positions on the outer side of the stirring shaft 211 follow the stirring shaft 211 and rotate inside the inner liner 130. The stirring blades 212 of the stirring components are designed with a 30-degree inclination angle. On the one hand, they can stir the liquid raw materials, and on the other hand, they can better cut into the solid raw materials for stirring. Moreover, the upper and lower position design can better stir the upper and lower layers of liquid and solid raw materials evenly, so that the liquid and solid raw materials are heated more evenly and the uniformity of heating is improved.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
