Description

Technical Field

[0001] This utility model relates to the field of fermenter technology, specifically to a fermenter for intelligent cultivation and monitoring of COD-degrading bacteria. Background Technology

[0002] COD-degrading bacteria are a combination of bacterial strains with the ability to degrade various organic substances. They can be applied to the treatment of various industrial wastewaters. COD-degrading bacteria need to be cultivated in a fermenter.

[0003] For example, the announcement number is CN218539656U (titled "An Ecological Fermentation Tank for Cultivating Edible Fungi"), which includes a fermentation tank. The fermentation tank has multiple sets of support legs at its bottom. A control console is located on the left side of the fermentation tank, and an edible fungi supply port is installed above the control console. A stirring device is installed inside the fermentation tank. A baffle plate is installed on the bottom wall of the fermentation tank. A discharge pipe is installed at the right end of the fermentation tank and is connected to the interior of the fermentation tank. The stirring device is fixedly connected to the fermentation tank by fasteners and includes a rotating shaft. A crushing agitator is fixedly connected to the rotating shaft via a connecting rod. The mixing paddle has a gear fixedly connected to the rotating shaft. The gear is fixedly connected to the rotating shaft by a limiting block. The rotating shaft and the crushing mixing paddle are distributed in multiple groups in the fermentation tank. During use, the mixing device generates heat during mixing, reducing the energy supply of the external heating device and reducing resource loss. After mixing, some catalyst is added through the catalyst supply port to improve the reaction efficiency of edible fungi, enabling the edible fungi to decompose quickly and form fertilizer that can be reused. This solves the problem that existing fermentation tanks do not have a mixing device, which leads to uneven heating of edible fungi in the fermentation tank, prolongs the heating time, and causes waste of resources.

[0004] The aforementioned fermenters only improve the uniformity of heating during fermentation by setting up a stirring structure. However, they cannot be sampled at any time during fermentation, which leads to inconvenience in monitoring the fermentation process. To address this, we provide a smart fermenter for the cultivation and monitoring of COD-degrading bacteria. Utility Model Content

[0005] The purpose of this invention is to provide a smart fermenter for the cultivation and monitoring of COD-degrading bacteria, in order to solve the problem mentioned in the background art that existing fermenters only improve the uniformity of heating during fermentation by setting a stirring structure, but cannot take samples at any time during fermentation, resulting in inconvenience in monitoring during fermentation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a COD-degrading bacteria intelligent culture and monitoring fermenter, including a stainless steel tank body, an inner tank body is provided inside the stainless steel tank body, the inner tank body and the stainless steel tank body are an integral structure, and a discharge port is provided at the bottom of the inner tank body, the discharge port and the stainless steel tank body are an integral structure.

[0007] Also includes:

[0008] The top cover plate is fixed to the upper end of the stainless steel tank by bolts. A drive motor is set at the center of the upper end of the top cover plate.

A through rod seat is integrally formed at the top position of the piston rod of the hydraulic cylinder, and a crossbeam is integrally formed on the outer wall of the top end of the linkage rod. The crossbeam is connected to the through hole inside the through rod seat.

[0010] A guide ring is sleeved on the outside of the linkage rod, and the linkage rod and the guide ring are movable through and through each other. A cross-shaped connecting seat is integrally formed at the lower end of the linkage rod, and an extraction cylinder is integrally formed at the lower end of the cross-shaped connecting seat.

[0011] Preferably, a support rod is integrally formed on one side of the outer wall of the guide ring, and a mounting seat is integrally formed at one end of the support rod. The mounting seat is fixedly connected to the top cover plate by screws.

[0012] Preferably, the inner tank is equipped with a stirring shaft, and the output shaft of the drive motor passes through the top cover plate and is welded to the top of the stirring shaft.

[0013] Preferably, the outer part of the guide ring is integrally formed with a sealing cap, which is connected to the top of the injection port.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention involves installing the mounting base onto the upper part of the top cover plate, then placing the extraction cylinder inside the inner tank, and simultaneously inserting the crossbeam rod into the rod holder. When sampling is required, a hydraulic cylinder drives the linkage rod downward, causing the extraction cylinder to fall to the bottom of the inner tank to collect the fermentation material. Then, the hydraulic cylinder lifts the extraction cylinder, and finally, the mounting base is removed, and the crossbeam rod is taken off the rod holder, allowing the extraction cylinder to be removed from the inlet. This achieves the purpose of facilitating the extraction of fermentation material and monitoring the fermentation status inside the fermenter. It overcomes the problem that existing fermenters only improve the uniformity of heating during fermentation through a stirring structure, but cannot take samples at any time during fermentation, leading to inconvenience in monitoring the fermentation process.
