Description

Technical Field

[0001] The utility model relates to the technical field of microbial inoculant production, in particular to an exhaust mechanism for a fermentation tank in microbial inoculant production. Background Technique

[0002] A microbial inoculant refers to a live microbial preparation made by using a porous substance as an adsorbent (such as peat and vermiculite) to adsorb the fermentation broth of the target microorganism (effective bacteria) after industrial production and propagation. This kind of inoculant is used for seed dressing or root dipping, and has the functions of directly or indirectly improving the soil, restoring soil fertility, preventing soil-borne diseases, maintaining the balance of the rhizosphere microbial flora, and degrading toxic and harmful substances. The proper use of agricultural microbial inoculants can increase the yield of agricultural products, improve the quality of agricultural products, reduce the use of chemical fertilizers, reduce costs, improve the soil, and protect the ecological environment. When producing microbial inoculants, an exhaust device for the fermentation tank is required.

[0003] In the prior art, when exhausting the gas inside the fermentation tank, it is often necessary to suck out the gas inside the fermentation tank through an exhaust pipe and a suction fan. However, since this kind of exhaust mechanism has a relatively single function and can only play the role of exhausting gas, it does not have the function of removing odors. When the gas with odors is discharged, it will pollute the surrounding environment, and some gases will pose a threat to the health of users, and it cannot well meet the usage requirements of people. Therefore, it is necessary to propose an exhaust mechanism for a fermentation tank in microbial inoculant production to solve the above-mentioned problems. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: An exhaust mechanism for a fermentation tank in microbial inoculant production, including a cylinder body, a connecting pipe penetrating and connected to the lower side of the cylinder body, and a suction fan. A limiting ring is fixedly connected inside the cylinder body. A first O-shaped groove is opened at the upper end of the limiting ring, and a first sealing ring is installed inside the first O-shaped groove. A filling ring is inserted inside the cylinder body and is pressed against the upper side of the first sealing ring. The lower side of the inner wall of the filling ring is fixedly connected with a mesh plate. Activated carbon located above the mesh plate is filled inside the filling ring. The upper end of the filling ring abuts against a cover plate. The upper end of the cover plate is fixedly connected with a connecting ring. A second O-shaped groove is opened on the outer wall of the connecting ring, and a second sealing ring that is pressed against the inner wall of the cylinder body is installed inside the second O-shaped groove. The upper end of the connecting ring is fixedly connected with a mounting plate located above the cylinder body. The suction fan is installed on the upper end of the mounting plate and its air inlet end penetrates through the mounting plate;

[0006] Both the left and right sides of the cylinder body are fixedly connected with fixing plates. The lower ends of the two fixing plates all penetrate and are threadedly connected with screw rods. The upper ends of the two screw rods are all rotatably connected with moving plates. The upper ends of the two moving plates are all rotatably connected with connecting shafts. The upper ends of the two connecting shafts are all fixedly connected with pressing plates that are pressed against the left and right sides of the upper end surface of the mounting disc.

[0007] In order to facilitate the discharged gas to pass through the cover plate, as an optimization of the exhaust mechanism of the microbial inoculant production fermentation tank of the present utility model, a plurality of uniformly distributed ventilation holes located inside the connecting ring are penetrated and opened on the upper end surface of the cover plate.

[0008] In order to facilitate improving the stability of the movement of the two moving plates, as an optimization of the exhaust mechanism of the microbial inoculant production fermentation tank of the present utility model, the two moving plates are respectively slidably connected with the left and right sides of the cylinder body through slide rails.

[0009] In order to prevent the positions of the two pressing plates from shifting during fixation, as an optimization of the exhaust mechanism of the microbial inoculant production fermentation tank of the present utility model, grooves are opened on both the left and right sides of the upper end surface of the mounting disc, and convex blocks that cooperate with the two grooves are fixedly connected to the lower ends of the two pressing plates.

[0010] In order to facilitate rotating the two screw rods, as an optimization of the exhaust mechanism of the microbial inoculant production fermentation tank of the present utility model, handles are fixedly connected to the lower ends of the two screw rods.

[0011] In order to facilitate connecting and fixing the exhaust port of the fermentation tank with the connecting pipe, as an optimization of the exhaust mechanism of the microbial inoculant production fermentation tank of the present utility model, a flange is installed at the lower end of the connecting pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By inserting the filling ring filled with activated carbon into the interior of the cylinder body, then inserting the cover plate and the connecting ring into the interior of the cylinder body, and the second sealing ring is pressed against the inner wall of the cylinder body, thereby the extrusion part between the two can be sealed. Then rotate the two pressing plates to make the positions of the two convex blocks vertically correspond to the two grooves, and then move the two pressing plates downward to press the filling ring downward until the filling ring is tightly pressed against the first sealing ring, thereby the extrusion part between the two can be sealed to complete the installation. During operation, the suction fan can suck the gas inside the fermentation tank out through the connecting pipe and the cylinder body, and the activated carbon removes the odor in the gas, further achieving the purpose of removing the odor of the discharged gas, thereby avoiding environmental pollution and preventing threats to the health of users.

[0033] Working principle:

[0034] First, add activated carbon into the interior of the filling ring 6, then insert the filling ring 6 into the interior of the cylinder body 2 until the filling ring 6 contacts the first sealing ring 5. Then insert the cover plate 8 and the connecting ring 9 into the interior of the cylinder body 2 until the cover plate 8 contacts the filling ring 6. At this time, the second sealing ring 11 is pressed against the inner wall of the cylinder body 2, and thus the extrusion part between the two can be sealed. Then, rotate the two pressing plates 17 respectively along with the two connecting shafts 16 until the positions of the two bumps 19 are vertically corresponding to the two grooves 18.
