[0012] The method of the fermentation tank defoaming system based on foam sensing comprises the following steps:

[0013] S1: Before the device starts working, if multiple tanks need to be connected, the operator will bring two adjacent tanks close to each other, make two adjacent threaded rods correspond to each other, and the threaded rods will enter the adjacent double-threaded tubes. The double-threaded tubes will be rotated, and the double-threaded tubes will be able to connect the two adjacent threaded rods. Then the operator will transport the fermentation liquid into the tank, and then place the connection cover on the top of the tank, insert the cross rod at the bottom of the transmission rod into the cross groove at the top of the rotating rod, and insert the insertion rod into the hole at the top of the adjacent connecting rod, thereby completing the installation of the fermentation tank;

[0014] S2: When the device starts working, the motor is started by an external power supply, the motor drives the transmission rod to rotate, the transmission rod drives the rotating rod to rotate through the cross rod, the rotating rod drives the stirring rod to rotate, the stirring rod stirs the fermentation liquid, after the stirring is completed, the fermentation liquid ferments, during the stirring and fermentation process, a large amount of foam will be generated, this scheme will adopt two ways to eliminate foam, which are respectively suitable for fermentation liquids and foams of different volumes;

[0015] S3: When the fermentation liquid volume inside the tank body contacts the floating plate, the floating plate will float upward, and the floating plate will drive the arc rod and the second T-block to move upward, and the floating plate will drive the fan-shaped filter plate, the movable ring, the adjustment plate, the movable plate and the first T-block to move upward, so that the fan-shaped filter plate is located on the surface of the fermentation liquid within the moving range of the second T-block, and then the motor drives the rotating rod to rotate through the transmission rod and the cross rod, and the rotating rod drives the movable plate to rotate through the first T-block, and the movable plate will contact the fixed plate during the rotation process, and the movable plate will drive the movable ring to rotate through the fixed plate, and the movable ring drives the adjustment plate to rotate, and the adjustment plate will contact the connecting plate during the rotation process, and the adjustment plate will drive the fan-shaped filter plate to rotate through the connecting plate, and the fan-shaped filter plate drives the limiting column to rotate, and the fan-shaped filter plate rotates on the top of the floating plate, and during the rotation of the fan-shaped filter plate, the foam on the surface of the fermentation liquid will be eliminated;

[0016] S4: If the foam capacity inside the tank exceeds the rotation elimination speed of the fan-shaped filter plate, after the foam contacts the foam sensing probe, the foam sensing probe will close the electromagnet through electrical connection. After the electromagnet is closed, the magnet loses attraction, and the swing plate swings from a horizontal state to a vertical state, while the arc frame loses the restriction of the swing plate. The arc frame will move downward rapidly due to the weight of the internal defoamer. During the downward movement of the arc frame, the elastic plate will contact the surface of the connecting cover, and the elastic plate will drive the baffle to swing. During the swinging of the baffle, the arc plate inside the arc frame will move downward, and the arc plate will drive the elastic rope to stretch, and one side of the bottom of the arc plate will contact the solid The fixed column and the side of the curved plate that does not contact the fixed column will cause the curved plate to be in an inclined state. When the curved plate is in an inclined state, the defoamer on the top of the curved plate will quantitatively flow into the bottom of the inner cavity of the curved frame and flow out through the holes at the bottom of the curved frame. The defoamer will flow into the tank body, thereby eliminating the foam inside the tank body. The first transparent plate and the second transparent plate on the surface of the tank body can observe the positions of the fermentation liquid, foam and foam sensing probe inside the tank body. The position of the foam sensing probe can be moved manually by pulling the rope. The rope drives the foam sensing probe to move through the adjustment ring and the elastic rod. After the rope is released, the foam sensing probe will return to its initial position.

[0017] S5: When the work is finished, the operator first takes out the connecting cover upwards, takes the connecting cover out from the top of the tank body, restores the position of the arc frame, pushes the arc frame upwards, and after the top of the arc frame contacts the L-shaped plate, starts the electromagnet and adjusts the swing plate, so that the magnet on one side of the swing plate contacts and adsorbs the electromagnet, limits the arc frame, adjusts the position of the baffle, and adjusts the arc plate to the top of the baffle. When the defoaming agent inside the arc frame is insufficient, the operator takes out the sealing plug, pours a small amount of defoaming agent into the arc frame through the feed pipe, and then moves the rotating rod upward. The rotating rod drives the stirring rod to move upward, and the rotating rod drives the fan-shaped filter plate upward through the stirring rod. The fan-shaped filter plate will gradually move away from the floating plate, and the rotating rod will move away from the vertical rod at the same time, so that the rotating rod and the surface of the fan-shaped filter plate can be cleaned more comprehensively, and the inside of the tank can also be cleaned more comprehensively.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention can realize that when the foam inside the tank body contacts the foam sensing probe, the foam sensing probe will turn off the electromagnet through electrical connection, and after the electromagnet is turned off, the magnet loses its magnetic attraction, the swing plate will be in a vertical state, the arc frame will move downward quickly, the arc frame will drive the elastic plate and the baffle to move, the elastic plate will swing after contacting the surface of the connecting cover, the arc plate inside the arc frame will move downward, one side of the bottom of the arc plate will contact the fixed column, the arc plate will tilt, and the defoaming agent on the top of the arc plate will flow into the tank body, thereby achieving a defoaming effect, the threaded rod and the double-threaded tube can connect multiple tank bodies, and the connecting cover can be taken out from the top of the tank body;

[0020] Through the mutual cooperation among the rotating rod, the fan-shaped filter plate, the vertical rod, the floating plate and other structures, the motor can drive the rotating rod to rotate through the transmission rod and the cross rod, and the rotating rod stirs the fermentation liquid inside the tank body through the stirring rod. At the same time, the rotating rod drives the fixed plate to rotate through the movable plate, and the fixed plate drives the movable ring and the adjusting plate to rotate. The adjusting plate drives the fan-shaped filter plate to rotate through the connecting plate, and the fan-shaped filter plate can eliminate foam intermittently. When the rotating rod needs to be disassembled, first take out the connecting cover, and then take out the rotating rod from the surface of the vertical rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The method of the fermentation tank defoaming system based on foam sensing comprises the following steps:

[0048] S1: Before the device starts working, if multiple tank bodies 1 need to be connected, the operator brings two adjacent tank bodies 1 close to each other, and makes two adjacent threaded rods 11 correspond to each other. The threaded rod 11 will enter the adjacent double-threaded tube 10, and the double-threaded tube 10 will be rotated. The double-threaded tube 10 can connect the two adjacent threaded rods 11. Then the operator transports the fermentation liquid into the tank body 1, and then places the connecting cover 2 on the top of the tank body 1, inserts the cross rod 7 at the bottom end of the transmission rod 6 into the cross groove at the top of the rotating rod 29, and inserts the insertion rod 43 into the hole at the top of the adjacent connecting rod 12, thereby completing the installation of the fermentation tank;

[0050] S3: When the fermentation liquid volume inside the tank body 1 contacts the floating plate 39, the floating plate 39 will float upward, and the floating plate 39 will drive the arc rod 38 and the second T-block 40 to move upward, and the floating plate 39 will drive the fan-shaped filter plate 31, the movable ring 32, the adjustment plate 33, the movable plate 35 and the first T-block 36 to move upward, so that the fan-shaped filter plate 31 is located on the surface of the fermentation liquid within the moving range of the second T-block 40, and then the motor 5 drives the rotating rod 29 to rotate through the transmission rod 6 and the cross rod 7, and the rotating rod 29 drives the movable plate 31 through the first T-block 36. 5 is rotated, the movable plate 35 will contact the fixed plate 34 during the rotation process, the movable plate 35 will drive the movable ring 32 to rotate through the fixed plate 34, the movable ring 32 will drive the adjusting plate 33 to rotate, the adjusting plate 33 will contact the connecting plate 45 during the rotation process, the adjusting plate 33 will drive the fan-shaped filter plate 31 to rotate through the connecting plate 45, the fan-shaped filter plate 31 drives the limiting column 37 to rotate, the fan-shaped filter plate 31 rotates on the top of the floating plate 39, and during the rotation process of the fan-shaped filter plate 31, the foam on the surface of the fermentation liquid will be eliminated;

[0051] S4: If the foam capacity inside the tank body 1 exceeds the rotation elimination speed of the fan-shaped filter plate 31, after the foam contacts the foam sensing probe 17, the foam sensing probe 17 will close the electromagnet 44 through electrical connection. After the electromagnet 44 is closed, the magnet 28 loses attraction, and the swing plate 27 swings from a horizontal state to a vertical state, and the arc frame 14 loses the restriction of the swing plate 27.
