Description

Technical Field

[0001] The utility model belongs to the technical field of biodegradation, and in particular relates to a continuous flow reactor for microbial degradation test. Background Art

[0002] In the study of the reaction mechanism, metabolic pathway and mechanism of microbial degradation of drugs, a large number of continuous reactors need to be applied. In this type of degradation test, multiple reactors need to be connected to facilitate the introduction or discharge of gas into the interior. For example, the "Water Earthworm-Microbial Symbiosis System Mud and Water Degradation Continuous Flow Reactor and Application" disclosed in Application No. 200910099943.3.

[0003] However, in actual application, it is found that the lengths of the pipes used for input and discharge are different. For example, a long pipe is needed for input to pass the gas into the bottom of the reactor. Conversely, an end pipe is needed for exhausting the gas to prevent the internal substances from hindering the removal of the gas. The reactors in existing equipment are mostly fixed structures, which makes the docking position of the pipe on the top of the reactor fixed. Different degradation tests use different pipe connection methods. Fixed reactors will make subsequent pipe connections inconvenient, and obstructions are likely to occur between the pipes, affecting the connection work between the reactors.

[0004] Based on this, the present utility model is proposed. Utility Model Content

[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] Please refer to Figure 1-Figure 3As shown, a continuous flow reactor for microbial degradation test comprises a bottom plate 1 and a reactor body 3, mounting cross beams 2 are symmetrically arranged on both sides of the upper surface of the bottom plate 1, the reactor body 3 is suspended between the two mounting cross beams 2, a discharge pipe 32 is arranged at the bottom of the reactor body 3, a control valve is arranged inside the discharge pipe 32, so as to control the discharge at the bottom of the reactor body 3, a sliding sleeve 22 is slidably installed on the surface of the mounting cross beam 2, mounting seats 31 are symmetrically arranged on both sides of the reactor body 3, the mounting seats 31 are fixed on the sliding sleeve 22 by bolts, so that the reactor body 3 can slide along the surface of the mounting cross beam 2, and then adjust the distance between two adjacent reactor bodies 3, the reactor body 3 is hollow inside and the top is open, a sealing cover plate 4 is installed on the top of the reactor body 3, and the sealing cover plate 4 can be opened to inspect the internal position, or to directly load the material through the top opening, and the sealing cover plate 4 can be opened to inspect the internal position, etc. The cover plate 4 seals the top opening of the reactor body 3 to ensure that the interior of the reactor body 3 is in a sealed state during the test. A through hole is opened in the center of the sealing cover plate 4. A rotating disk 8 is rotatably installed in the central through hole of the sealing cover plate 4. The optional axis of the rotating disk 8 coincides with the axis of the reactor body 3. The cross-section of the rotating disk 8 is stepped, with a larger upper portion and a smaller lower portion. The lower portion of the rotating disk 8 is adapted to the internal size of the through hole. A sealing gasket 82 is provided on the outer side of the bottom of the rotating disk 8. The sealing gasket 82 is placed on the lower surface of the sealing cover plate 4 to form an I-shaped structure through the upper portion of the rotating disk 8 and the sealing gasket 82 to ensure that the rotating disk 8 can only rotate along the axis. Two insertion tubes 83 are symmetrically and vertically installed on the surface of the rotating disk 8. The bottoms of the two insertion tubes 83 are both placed inside the reactor body 3. One of the two insertion tubes 83 is a long tube and the other is a short tube. The long tube is used to pass gas into the interior, and the short tube is used to discharge gas.

[0022] Please refer to Figure 2 and Figure 3 As shown, limiting grooves 81 are symmetrically provided on both sides of the upper surface of the rotating disk 8, and the positions of the two limiting grooves 81 correspond to the insertion tubes 83, so that the rotating disk 8 can be effectively controlled through the limiting grooves 81. The front side of the upper surface of the sealing cover plate 4 is symmetrically provided with fixing bolts 5, and the surfaces of the two fixing bolts 5 are rotatably installed with swing rods 6. The two swing rods 6 are respectively placed on both sides of the rotating disk 8, and the sides of the two swing rods 6 close to each other at the rear ends are provided with clamping heads 61. The clamping heads 61 are adapted to the internal dimensions of the limiting grooves 81. The cooperation between the two can ensure that the rotating disk 8 cannot rotate, and then the positions of the two insertion tubes 83 of different lengths can be fixed.

[0023] Among them, a toggle bolt 62 is provided on the upper surface of the front end of the swing rod 6, and the toggle bolt 62 is placed on the outside of the sealing cover plate 4, so as to control the swing rod 6 through the outside. A tension spring 7 is connected between the two swing rods 6, and the tension spring 7 is placed between the fixing bolt 5 and the clamping head 61. The tension of the tension spring 7 is used to make the ends of the two swing rods 6 close to the clamping head 61 close to each other when no force is applied, so that the clamping head 61 can cooperate with the limiting groove 81 to keep it fixed.

[0024] Please refer to Figure 1 As shown, positioning holes 21 are evenly opened on the outer surfaces of the two mounting beams 2, and bolts matching the positioning holes 21 penetrate the outer sides of the sliding sleeves 22, so that the position of the reactor body 3 is kept stable through the cooperation between the bolts and the positioning holes 21.

[0025] A transparent observation window 33 is provided on one side of the reactor body 3 which is away from each other, so as to facilitate observation of the internal situation of the reactor body 3 , and scale values ​​are evenly engraved on the surface of the transparent observation window 33 .

[0026] The working principle of the utility model is as follows: the reactor body 3 on the inner side is kept in a suspended state by means of the mounting cross beams 2 on both sides, and the position of the reactor body 3 can be adjusted according to actual conditions to facilitate the connection of the top pipeline. When the reactor body 3 moves, the sleeves 22 at both ends thereof can be driven to move along the surface of the mounting cross beam 2, and then the sleeves 22 are kept fixed by the mutual cooperation of the bolts and the positioning holes 21. After the raw materials are poured in through the top of the reactor body 3, they are sealed by the sealing cover plate 4. The transparent observation window 33 can effectively observe the internal reaction conditions. Due to the tension of the tension spring 7, the two swing rods 6 have a force to approach each other on one side close to the clamping head 61, and then the overall stability of the rotating disk 8 can be maintained by the mutual cooperation of the clamping head 61 and the limiting groove 81. When the pipeline needs to be docked, the two toggle bolts 62 can be pinched by hand to make the two toggle bolts 62 close to each other, so that the two clamping heads 61 at the rear end are separated from the limiting groove 81, and then the rotating disk 8 can be rotated to adjust the position of the two insertion pipes 83 of different lengths to facilitate the docking of the pipeline.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
