Description

Technical Field

[0001] This utility model belongs to the field of fermentation equipment technology, specifically relating to a rapid breaking and separation device for vitamin B2 fermentation foam. Background Technology

[0002] Foaming is a common phenomenon during the fermentation of vitamin B2. If the foam is not eliminated in time, it will occupy a large amount of tank volume, affecting the flow rate of excipients. Furthermore, vitamin B2 fermentation requires aeration and stirring; excessive foam hinders gas exchange during metabolism, thus reducing production efficiency. In existing technologies, the fixed position of the defoaming components in the fermenter results in poor defoaming effect and low efficiency, which is detrimental to fermentation production. Therefore, there is an urgent need for a rapid foam breaking and separation device for vitamin B2 fermentation to solve the above technical problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a rapid foam breaking and separation device for vitamin B2 fermentation. The device includes a fermentation tank containing a stirring paddle. The stirring paddle comprises a vertical stirring shaft and a stirring rod fixed to the stirring shaft. The upper end of the stirring shaft extends outside the fermentation tank and is connected to a drive assembly. A foam breaking assembly, movable vertically, is mounted on the stirring shaft inside the fermentation tank and is located on the stirring shaft above the stirring rod. The drive assembly drives the stirring shaft to rotate, and the stirring rod stirs the material inside the fermentation tank.

[0004] The foam breaking assembly includes a circular defoaming net and a vertical telescopic rod. The vertical telescopic rod can be an electric push rod or a hydraulic rod. The stirring shaft passes through the center of the defoaming net and has a vertical channel inside. The channel coincides with the central axis of the stirring shaft. Two vertical elongated through holes are symmetrically arranged on the side wall of the stirring shaft inside the fermentation tank, and the two elongated through holes communicate with the channel. The fixed end of the vertical telescopic rod is fixed to the top of the stirring shaft, and the telescopic end of the vertical telescopic rod extends into the channel and is connected to two horizontal connecting rods. The connecting rods pass through the corresponding elongated through holes and are fixedly connected to the defoaming net. The extension and retraction of the vertical telescopic rod can drive the defoaming net to move up and down inside the fermentation tank, thereby achieving the defoaming effect. At the same time, the defoaming net can rotate with the stirring shaft, and can cut the foam in the horizontal direction, further improving the defoaming effect.

[0005] Preferably, the drive assembly includes a motor, a first bevel gear, and a second bevel gear. The first bevel gear is fixed to a stirring shaft outside the fermenter, and the second bevel gear meshes with the first bevel gear. The motor is fixed to the fermenter, and its output shaft is connected to the second bevel gear. The vertical telescopic rod is an electric push rod, which is connected to a power source via a conductive slip ring or is battery-driven. This configuration allows the vertical telescopic rod to extend and retract without affecting its own extension and retraction while rotating with the stirring shaft.

[0006] Preferably, the lower surface of the defoaming net is fixed with multiple defoaming spikes, which are distributed in an Archimedean spiral pattern on the defoaming net. The defoaming spikes can improve the foam breaking effect when the defoaming net rotates with the stirring shaft, resulting in a better defoaming effect.

[0007] Preferably, the defoaming spikes are triangular pyramidal in shape. They can cut the foam at different angles, further improving the defoaming effect.

[0008] Preferably, the defoaming net is equipped with a foam-absorbing component, which includes a foam-absorbing tube, an annular fixed tube, and an annular rotating tube. The annular fixed tube is fixed to the inner wall of the top of the fermentation tank and is connected to a conduit. One end of the conduit extends out of the fermentation tank and is connected to a foam storage tank. A pump is connected to the conduit. The outer ring surface of the annular rotating tube is rotatably connected to and communicates with the inner ring surface of the annular fixed tube through a bearing. The inner ring surface of the annular rotating tube is fixedly connected to a stirring shaft. A foam inlet tube is fixedly connected to the lower surface of the annular rotating tube. The foam inlet tube is connected to the foam-absorbing tube through a spring tube. The foam-absorbing tube is fixed to the defoaming net, and foam-absorbing holes are provided on the side wall of the foam-absorbing tube. This setup allows unremoved foam to be sucked into a foam storage tank for recycling. During the suction process, the suction tube rotates with the defoaming net, suctioning foam from different locations in the fermentation tank above the defoaming net. This further improves the effectiveness and efficiency of foam removal in the fermentation tank. The suction tube remains positioned on the defoaming net, enhancing its stability and effectively preventing the material inside the fermentation tank from being sucked away.

[0009] Working principle: During fermentation in the fermenter, the stirring shaft rotates, driving the stirring rod to stir the material. At the same time, the defoaming net can rotate with the stirring shaft, cutting the foam horizontally to defoam. When rotation is not required, the vertical telescopic rod moves the defoaming net up and down to defoam. In other words, the defoaming net can move up and down and rotate with the stirring shaft, defoaming foam at different heights. At the same time, the foam suction component can suck up the remaining foam into the foam storage tank for centralized treatment, further improving the defoaming effect.

[0010] This invention has the following advantages: the defoaming net can move up and down and rotate with the stirring shaft, which can defoam foam at different heights in the fermentation tank. At the same time, the foam suction component can suck the undefoamed foam into the foam storage tank for centralized treatment. The defoaming effect is good and the efficiency is high, which is beneficial to fermentation production. Attached Figure Description

A foam breaking assembly that can move up and down is provided on the stirring shaft 2 inside the fermentation tank 1. The foam breaking assembly is located on the stirring shaft 2 above the stirring rod. The driving assembly drives the stirring shaft 2 to rotate, and the stirring rod stirs the material in the fermentation tank 1.

[0016] The foam breaking assembly includes a circular defoaming net 3 and a vertical telescopic rod 6. The vertical telescopic rod 6 can be an electric push rod or a hydraulic rod. The stirring shaft 2 passes through the center of the defoaming net 3. The stirring shaft 2 has a vertical channel inside, which coincides with the central axis of the stirring shaft 2. Two vertical elongated through holes 5 are symmetrically arranged on the side wall of the stirring shaft 2 inside the fermentation tank 1, and the two elongated through holes 5 communicate with the channel. The fixed end of the vertical telescopic rod 6 is fixed to the top of the stirring shaft 2, and the telescopic end of the vertical telescopic rod 6 extends into the channel and is connected to two horizontal connecting rods 10. The connecting rods 10 pass through the corresponding elongated through holes 5 and are fixedly connected to the defoaming net 3. The extension and retraction of the vertical telescopic rod 6 can drive the defoaming net 3 to move up and down inside the fermentation tank 1, thereby achieving the defoaming effect. At the same time, the defoaming net 3 can rotate with the stirring shaft 2, and the defoaming net 3 can cut the foam in the horizontal direction, further improving the defoaming effect.

[0017] The drive assembly includes a motor 9, a first bevel gear 7, and a second bevel gear 8. The first bevel gear 7 is fixed to the stirring shaft 2 outside the fermentation tank 1, and the second bevel gear 8 meshes with the first bevel gear 7. The motor 9 is fixed to the fermentation tank 1, and the output shaft of the motor 9 is connected to the second bevel gear 8. The vertical telescopic rod 6 is an electric push rod, which is connected to a power source through a conductive slip ring or is battery-driven. This design allows the vertical telescopic rod 6 to extend and retract while rotating with the stirring shaft 2 without affecting its own extension and retraction.

[0018] The lower surface of the defoaming net 3 is fixed with a plurality of defoaming spikes 4, which are distributed in an Archimedean spiral pattern on the defoaming net 3. The defoaming spikes 4 can improve the foam breaking effect when the defoaming net 3 rotates with the stirring shaft 2, thus making the defoaming effect better.

[0019] The defoaming spikes 4 are triangular pyramidal in shape. They can cut the foam at different angles, further improving the defoaming effect.

[0020] Example 2 like Figure 3-5As shown, the difference between this embodiment and Embodiment 1 is that the defoaming net 3 is equipped with a foam-absorbing component. The foam-absorbing component includes a foam-absorbing tube 11, an annular fixed tube 13, and an annular rotating tube. The annular fixed tube 13 is fixed on the inner wall of the top of the fermentation tank 1. The annular fixed tube 13 is connected to a conduit 16. One end of the conduit 16 extends out of the fermentation tank 1 and is connected to a foam storage tank. A material pump 17 is connected to the conduit 16.

Foam-absorbing holes 18 are provided on the side wall of the foam-absorbing tube 11. This setup allows unremoved foam to be sucked into a foam storage tank for recycling. During the foam suction process, the suction tube 11 rotates with the defoaming net 3, suctioning foam from different positions in the fermentation tank 1 above the defoaming net 3. This further improves the effectiveness and efficiency of foam removal in the fermentation tank 1. The suction tube 11 is always positioned on the defoaming net 3, which improves the stability of the suction tube 11 and effectively prevents the material in the fermentation tank 1 from being sucked away.
