Biological fermentation tank convenient to clean

Abstract

The invention discloses a biological fermentation tank convenient to clean, which comprises a tank body. A bearing is connected to the bottom part of an inner wall of the tank body in a clamping way;a rotary shaft is inserted into the bearing; a first belt pulley is fixedly connected to the bottom end of the rotary shaft; a drive motor is fixedly connected to a lower surface of the tank body; anoutput shaft of the drive motor is fixedly connected with a second belt pulley; the first belt pulley and the second belt pulley are in transmission connection through a belt; a gear box is fixedly connected to the top end of the rotary shaft. According to the biological fermentation tank convenient to clean provided by the invention, the motor operates to drive a second bevel gear to rotate, thesecond bevel gear drives a threaded rod to rotate, and a screw thread is limited by a limiting rod and a slide sleeve so as to be incapable of rotating, so that the screw thread sleeves on the threaded rod so as to move along a direction of the threaded rod; a screw thread sleeve moves outwards to enable a scraper blade on the outer side of a stir rod to be in lap joint with the inner wall of thetank body, so that the stir rod can scrape residues attached to the inner wall of the tank body when rotating, and not only is the fermentation tank clean in discharging, but also the fermentation tank is convenient to clean.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a biological fermentation tank which is easy to clean. Background technique [0002] Fermentation tank refers to a device used in industry for microbial fermentation. Its main body is generally a main cylinder made of stainless steel plate, and the structure of the fermenter used for anaerobic fermentation (such as producing alcohol and solvent) can be relatively simple. The fermenter used for aerobic fermentation (such as the production of antibiotics, amino acids, organic acids, vitamins, etc.) needs to continuously feed a large amount of sterile air into the tank, and in order to consider the utilization rate of the air, the structure of the fermenter is comparatively comparative. Complex, commonly used mechanical stirring fermenter, bubbling fermenter and airlift fermenter. [0003] The fermenter needs to discharge the material after the fermentation is comp...
