[0036] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific embodiments described below.

[0037] like Figures 1 to 4 As shown, the utility model provides a stirring reaction device, which includes a tank body 1, an end cover 2, a stirring assembly 3 and a cleaning assembly 4. The end cover 2 can be buckled with the tank body 1 to form a reaction chamber, which is suitable for accommodating materials for biological reactions. The stirring assembly 3 includes a stirring member 31 and a driving member 32. The stirring member 31 is arranged in the reaction chamber, and the driving member 32 can drive the stirring member 31 to rotate. The cleaning assembly 4 includes a water supply pipe 41 and an air supply unit 42. The water supply pipe 41 and the air supply unit 42 are both detachably connected to the end cover 2. One end of the water supply pipe 41 is connected to the liquid supply device, and the other end passes through the end cover 2 and extends into the reaction chamber to supply water to the reaction chamber; one end of the air supply unit 42 is connected to the air supply device, and the other end passes through the end cover 2 and extends into the reaction chamber to supply air to the reaction chamber.

[0038] Based on the above technical solution, the stirring assembly 3 can be used to stir the material in the reaction chamber, so that the reaction of the material is more uniform. The air supply unit 42 can also be used to supply air to the reaction chamber to achieve an aerobic reaction. During the cleaning process, water can be sprayed into the reaction chamber through the water supply pipe 41, and the stirring assembly 3 can stir the water in the reaction chamber to clean the reaction chamber and the components in the reaction chamber, thereby reducing the cleaning burden. During the cleaning process, air can be supplied to the reaction chamber through the air supply unit 42 to achieve aeration cleaning, thereby improving the cleaning effect. In addition, most of the components in the reaction chamber can be moved with the end cover 2 and removed from the reaction chamber or placed in the reaction chamber, thereby reducing the need to insert hands and installation tools into the reaction chamber, thereby reducing the risk of introducing contaminants into the reaction chamber, and the water supply pipe 41 and the air supply unit 42 can be detachably connected to the end cover 2, so that the water supply pipe 41 and the air supply unit 42 can be disassembled for further deep cleaning after disassembly, thereby improving the cleaning effect of the stirring reaction device.

[0039] like Figure 4 As shown, the stirring member 31 can be arranged at the bottom of the reaction chamber, so that when the stirring member 31 rotates, it drives the material in the reaction chamber to circulate up and down, which can make the material mixing more uniform and is conducive to the full reaction of the material. During the cleaning process, only less water needs to be injected into the reaction chamber, and the inner wall of the entire tank body 1 can be flushed under the drive of the stirring member 31, which can have a certain water-saving effect.

[0040] The gas supply unit 42 includes a gas supply pipe 421 and a gas equalizing pipe 422. One end of the gas supply pipe 421 passes through the reaction chamber and is connected to the gas supply device, and the other end is connected to the gas equalizing pipe 422. The gas equalizing pipe 422 is arranged at the bottom of the reaction chamber. The arrangement of the gas equalizing pipe 422 can evenly distribute the gas entering the reaction chamber, and the gas will move upward after entering the reaction chamber. Therefore, arranging the gas equalizing pipe 422 at the bottom of the reaction chamber can enable the gas to fully contact with the material during the upward movement, which is conducive to a fully uniform aerobic reaction of the material. In the cleaning process, the gas will be ejected from the gas equalizing pipe 422 in the form of small bubbles. The ejected small bubbles can burst when they hit the wall of the reaction chamber and the parts in the reaction chamber, so as to pry the materials attached to the wall and parts to obtain a better cleaning effect.

[0041] It can be understood that a gap can be reserved between the stirring member 31 and the bottom wall of the reaction chamber, and the gas equalizing pipe 422 is arranged in the gap between the stirring member 31 and the bottom wall of the reaction chamber, so that the gas ejected from the gas equalizing pipe 422 can be further broken down and refined by the stirring member 31 during the upward movement, so that the gas can be more evenly dispersed into the reaction chamber, which is conducive to the aerobic reaction of the material. In the cleaning process, the bubbles ejected from the gas equalizing pipe 422 can be broken into smaller bubbles by the stirring member 31 and thrown to all corners of the reaction chamber, which can more effectively clean the dead corners in the reaction chamber.

[0042] Specifically, if Figures 7 to 10 As shown, the air equalizing pipe 422 is detachably connected to the air supply pipe 421 so that the air equalizing pipe 422 and the air supply pipe 421 can be cleaned separately, so as to shorten the distance between the inner wall of each section of the pipe that needs to be cleaned, and reduce the number of bends of the inner wall of each section of the pipe that needs to be cleaned or reduce the degree of bends, so as to obtain a better cleaning effect. The air equalizing pipe 422 is evenly distributed on one side of the bottom wall facing the reaction chamber, and the air outlet 4221 is directed downward to deliver oxygen to the material at the bottom of the reaction chamber, so that the aerobic reaction is more uniform, and during the cleaning process, the aeration cleaning of the bottom wall of the reaction chamber can be achieved, and the cleaning effect is better. In addition, it can be understood that, if Figure 9 As shown, the air equalizing pipe 422 can have multiple models, and the size and density of the air outlet 4221 on each model of the air equalizing pipe 422 are different, so that different air equalizing pipes 422 can be selected to connect with the air supply pipe 421 according to the oxygen consumption requirements. Generally, the greater the oxygen consumption, the larger the air outlet 4221 on the air equalizing pipe 422 used and the denser the arrangement; the smaller the oxygen consumption, the smaller the air outlet 4221 on the air equalizing pipe 422 used and the denser the arrangement. The air outlet 4221 can be a circular or polygonal hole, such as a regular hexagonal hole, and the closer the air outlet 4221 is to a circular hole, the better, so as to reduce dead angles and facilitate cleaning of the air outlet 4221.

[0043] The gas equalizing pipe 422 can be configured to include a main body 4222 and at least one auxiliary body 4223. The main body 4222 is detachably connected to the gas supply pipe 421, and the auxiliary body 4223 is detachably connected to the main body 4222. The main body 4222 and the auxiliary body 4223 are configured to make way for the stirring member 31 so that the gas equalizing pipe 422 can be installed in the gap between the stirring member 31 and the bottom wall of the reaction chamber.

[0044] Specifically, if Figure 8As shown, in a feasible embodiment, the main body 4222 is configured to be semicircular, the middle part of the tube body of the main body 4222 is connected to the air supply pipe 421, and two auxiliary tube bodies 4223 are configured, each auxiliary tube body 4223 is circular, and is smaller than a quarter of a circle, so that after the two ends of the main body 4222 are screwed with the corresponding auxiliary tube bodies 4223, they form an open ring structure with a clearance gap. The clearance gap is provided, on the one hand, so that when the air supply unit 42 has sufficient space for horizontal movement, the base on the stirring member 31 for connecting to the inner bottom wall of the tank body 1 can pass through the clearance gap to facilitate the removal of the air supply unit 42. On the other hand, if the air supply unit 42 does not have sufficient space for horizontal movement, the auxiliary tube body 4223 can also be unscrewed first to facilitate the removal of the air supply unit 42.

[0045] like Figure 10 As shown, in another feasible embodiment, the main body 4222 can also be set to a semicircular arc shape, the middle part of the tube body of the main body 4222 is connected to the air supply pipe 421, the auxiliary tube body 4223 is semicircular, and a slot 4224 is formed on one of the connecting ends of the main body 4222 and the auxiliary tube body 4223, and a convex ring 4225 that cooperates with the slot 4224 is formed on the other end. The insertion direction of the convex ring 4225 in the slot 4224 is perpendicular to the axial direction of the main body 4222 and the auxiliary tube body 4223, and the auxiliary tube body 4223 is clamped with the main body 4222 through the cooperation of the convex ring 4225 and the slot 4224, thereby forming a complete annular air distribution pipe 422, so as to achieve more uniform The gas is evenly distributed, and the snap-on connection method can achieve quick disassembly and assembly. In addition, it can be understood that when the slot 4224 can be a U-shaped slot, but is not limited to a U-shaped slot, as long as the convex ring 4225 can be snapped into the slot 4224, there will be no relative movement between the main body 4222 and the auxiliary tube body 4223 in the horizontal direction, and the convex ring 4225 can be received by the slot 4224 or the slot 4224 can be hung on the convex ring 4225, so that there will be no relative movement between the main body 4222 and the auxiliary tube body 4223 in the vertical direction, and there is no need to set a seal at the snap-on connection between the main body 4222 and the auxiliary tube body 4223, and the gas escaping from the snap-on connection can also be used as part of the gas equalization function.

[0046] The stirring assembly 3 can be a magnetic stirrer, and the corresponding stirring member 31 is as follows Figure 6 The stirring paddle shown in the figure has a driving member 32 placed on the outside of the tank body 1 and in contact with the outer bottom wall of the tank body 1. The driving member 32 and the stirring paddle can be electromagnetically coupled to drive the stirring paddle to rotate (this is a prior art and will not be described here). The stirring assembly 3 uses a magnetic stirrer to facilitate the removal of the stirring member 31 from the reaction chamber for cleaning and to improve the sealing of the reaction chamber.

[0047] Further, if Figure 5 As shown, the portion of the water supply pipe 41 located in the reaction chamber is provided with a plurality of water outlet holes 411 , and the water flow ejected from the water outlet holes 411 can be more evenly directed onto the wall surface of the reaction chamber, thereby enabling the wall surface of the reaction chamber to be cleaned more evenly.

[0048] In addition, if Figures 1 to 3 As shown, the cleaning component 4 may further include a liquid collecting tank 43 for collecting waste liquid generated when cleaning the reaction chamber. Accordingly, the bottom of the tank body 1 is opened, and the liquid collecting tank 43 is provided with a liquid inlet, which is connected to the liquid outlet via a pipeline, and a crushing device (such as a shear stirring paddle) is provided at the liquid inlet to crush large-sized solid materials in the reaction chamber for easy collection. It can be understood that the crushing device can also be provided at the liquid outlet to prevent clogging of the pipeline. In addition, a one-way valve can also be provided on the end cover 2 to discharge the gas in the reaction chamber to ensure that the gas pressure in the reaction chamber is within a safe range.

However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.
