Description

Technical Field

[0001] The utility model belongs to the technical field of biotechnology research and development, and particularly relates to a biodegradation tank for biotechnology research and development. Background Art

[0002] Biodegradation refers to the process by which microorganisms metabolize and degrade organic matter into simple organic or inorganic substances, thereby facilitating the disposal of organic waste. Therefore, people attach great importance to accelerating the research and development and practicality of microbial decomposition devices.

[0003] The biodegradation tank is an important equipment for biotechnology research and development experiments. Reactants are placed in the reaction tank and reagents are added to accelerate the decomposition of the reactants. At present, biomass samples are usually crushed before being placed in the reaction tank, but there is often insufficient crushing, which affects the decomposition rate. Therefore, a crushing device is also installed in the tank to facilitate further crushing of the biomass samples.

[0049] Further, by Figure 1 and Figure 2As shown, in this embodiment, two fixed seats 41 are symmetrically fixed to the outer wall of the tank body 3, two rolling rollers 42 are distributed in parallel, and are rotatably mounted between the two fixed seats 41 using a fixed shaft 421, a No. 1 drive motor 43 is fixed on the fixed seat 41, and is used to drive the rolling roller 42 to rotate, and a gear 44 is fixed on each of the two fixed shafts 421, and the two gears 44 are meshed. After adopting the above scheme, when in use, the No. 1 drive motor 43 is started to drive the rolling roller 42 to rotate, and the two rolling rollers 42 are rotated on the two gears 44. The two rollers 42 rotate relative to each other under the meshing action, and the biomass sample is put into the tank body 3 from the feeding port 311. The biomass sample is first crushed and pulverized by the two relatively rotating crushing rollers 42. Then the biomass sample falls into the tank body 3, and the reagent is added and the stirring mechanism 5 is started to quickly mix the biomass sample with the reagent to decompose the biomass sample. The decomposed sample liquid is discharged from the feeding port 32. The utility model crushes and pulverizes the biomass sample by the two crushing rollers 42, and the crushing is more sufficient, so that the decomposition efficiency is effectively improved.

[0050] It should be noted that valves are evenly arranged on the loading port 311 and the unloading port 32. The valves need to be closed during the decomposition period, and the corresponding valves are opened in the loading and unloading stages respectively.

[0051] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, a material guiding mechanism 6 is further included, which is fixed on the bottom surface of the top cover 31 and communicated with the feeding port 311, and the material guiding mechanism 6 includes: a circular tube section 61, a flared transition section 62 and a rectangular tube section 63.

After adopting the above scheme, the biomass sample put into the feeding port 311 will fall into the circular tube section 61, and then be discharged along the flared transition section 62 and the rectangular tube section 63. The rectangular tube section 63 can reliably ensure that the biomass sample will fall into the inner space of the two rolling rollers 42, ensuring that the biomass sample is fully crushed and crushed.

[0052] Optionally, by Figure 1 and Figure 3As shown, in this embodiment, the stirring mechanism 5 includes: a rotating column 51, a stirring rod 52 and a No. 2 driving motor 53. The rotating column 51 is rotatably installed on the bottom surface of the top cover 31, the stirring rod 52 is detachably installed on the rotating column 51, and the No. 2 driving motor 53 is fixed to the top surface of the top cover 31 to drive the rotating column 51 to rotate. After adopting the above scheme, when in use, the No. 2 driving motor 53 is started to drive the rotating column 51 to rotate, and the rotating column 51 drives the stirring rod 52 to rotate to stir the biomass sample and the reagent, so that the biomass sample and the reagent are quickly mixed and the biomass sample is decomposed.

[0053] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, it also includes: an internal threaded tube 511, the internal threaded tube 511 is fixed on the rotating column 51, the stirring rod 52 has an external thread and is screwed into the internal threaded tube 511 through a threaded engagement method, thereby realizing the detachable installation of the stirring rod 52.

The cleaning plate 10 is elastically connected to the adapter plate 9, and the rubber scraper 11 is bonded and fixed to the cleaning plate 10. After adopting the above scheme, when the stirring rod 52 rotates, it will simultaneously drive the adapter plate 9, the cleaning plate 10 and the rubber scraper 11 to make a circular motion, and the rubber scraper 11 will scrape off the raw materials adhered to the inner wall of the tank body 3.

[0055] Optionally, by Figure 1 、 Figure 3 and Figure 5 As shown, this embodiment also includes: an adjusting screw 12, an adjusting nut 13 and a telescopic spring 14.

In order to avoid the adapter plate 9 from rotating during operation, a plurality of equally spaced sleeves 91 are fixed on the adapter plate 9, and the end of the stirring rod 52 is directly inserted into the sleeve 91.

[0057] It should be further explained that when the adapter plate 9 is made of elastic material, the stirring rod 52 can also be rotatably connected to the adapter plate 9 using bearings and other structures. When installing or removing the stirring rod 52, the adapter plate 9 can be bent to avoid it, and the adapter plate 9 can also be directly fixed to the end of one of the stirring rods 52. The above-mentioned effect can also be achieved by using welding, bolts and other fixing methods without affecting the installation and removal of the stirring rod 52.
