Description

Technical Field

[0001] The invention relates to the technical field of fermentation tank equipment, in particular to an asymmetric container structure and a rapid volume measurement method thereof. Background Art

[0002] A fermenter is an industrial device used for microbial fermentation. Its main body is typically a cylindrical stainless steel plate with a volume ranging from 1m³ to several hundred m³. Design and fabrication require a rigorous and rational structure, resistance to steam sterilization, operational flexibility, minimal internal attachments (to avoid dead corners), strong material and energy transfer capabilities, and adjustable features for easy cleaning and reduced contamination. These tanks are suitable for the production of a variety of products while minimizing energy consumption. Fermenters used for anaerobic fermentation (such as alcohol and solvent production) can be relatively simple in structure. Fermenters used for aerobic fermentation (such as the production of antibiotics, amino acids, organic acids, and vitamins) require continuous flow of large quantities of sterile air, and to optimize air utilization, their structures are relatively complex. Commonly used fermenters include mechanically agitated, bubbling, and airlift types. Dairy and alcohol fermentation is a sterile, pollution-free process. Fermenters utilize aseptic systems to avoid and prevent contamination from airborne microorganisms, significantly extending the shelf life and purity of the products. Specially designed sterile breathing vents or sterile positive pressure fermentation systems are installed within the tanks. Milo plates or labyrinth-style jackets are installed within the tanks to allow for circulation of heating or cooling media. Fermenter capacities range from 300 to 15,000 liters. Fermenters can be categorized by application, including small-scale laboratory fermenters, pilot production fermenters, and large-scale fermenters.

[0003] Patent No. CN105004395B This invention discloses a device, container, and method for measuring the volume of liquid in a container based on pressure sensing, wherein the measuring device includes a compression member, which can be sealed and connected to the container to be detected to form a sealed space in the container, and can compress the gas in the sealed space under the action of an external force, and the volume value of the compressed gas is a certain value; a pressure sensor and a force transmission member, the force transmission member can convert the air pressure in the sealed space into a pressure applied to the pressure sensor, the area value of its force-bearing surface is a certain value, and the pressure sensor can detect the pressure value from the force transmission member before and after compression; an air pressure sensor for detecting the ambient air pressure value; and a controller. The present invention can accurately measure the volume of liquid in a container, can effectively eliminate the influence of liquid shaking on the measurement results, and has good measurement stability; it can be used with containers of different materials, functions, and capacities, and has strong versatility.

[0004] However, there are several issues with measuring liquid levels within existing fermentation tanks. 1. Current fermentation tank level gauges can only measure the height of the liquid level. Due to the presence of elliptical heads, air inlet pipes, baffles, agitator shafts, and paddles at various locations within the fermentation tank, it's difficult to directly convert height into liquid volume or weight using a fixed formula. This makes it inconvenient for operators and eliminates the convenience of using a level gauge. 2. Current fermentation tanks lack a device to detect the direction of fluid flow within their interior. This can easily lead to uneven mixing due to corners forming during stirring, reducing product quality and making it difficult to detect design flaws within the tank. Summary of the Invention

[0005] The object of the present invention is to provide an asymmetric container structure and a rapid volume measurement method thereof to solve the problems raised in the above background technology.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: an asymmetric container structure, comprising a fermentation tank, a volume measurement component disposed on the surface of the fermentation tank, and a fluid measurement component disposed inside the fermentation tank;

[0007] The bottom of the fermentation tank is detachably connected to a base;

[0008] The volume measurement assembly includes a connecting plate fixedly connected to the surface of the base, a horizontal plate detachably connected to one side of the connecting plate, and a controller detachably connected to the surface of the horizontal plate. The controller measures the interior of the fermenter to obtain a data graph, and the internal volume of the fermenter is measured using the data graph.

[0009] The first connecting block and the second connecting block are made of conductive material.

[0010] Preferably, a liquid inlet pipe is embedded and connected to the surface of the fermentation tank, and an air inlet pipe is detachably connected to the surface of the fermentation tank.

[0011] Preferably, a stirring shaft is provided inside the fermentation tank, and a plurality of stirring blades are detachably connected to the surface of the stirring shaft.

[0012] Preferably, a plurality of filter screens are detachably connected to the surface of the stirring shaft, and a plurality of baffles are detachably connected to the interior of the fermentation tank.

[0013] Preferably, a liquid level meter is provided inside the fermentation tank, and a flow meter is provided inside the fermentation tank.

[0014] Preferably, the fluid measurement assembly comprises a shell detachably connected to the inner wall of the fermentation tank, a slot is provided inside the shell, and a vertical block is cooperatively connected to the top of the inner side of the slot.

[0015] Preferably, the surface of the vertical block is detachably connected to a first connecting block, and the sides of the vertical block are cooperatively connected to a rotating shaft.

[0016] Preferably, one end of the rotating shaft is detachably connected to a vertical plate, and one end of the vertical plate is inlaid with a second connecting block.

[0017] Preferably, a wire is connected to the surface of the second connection block, and the second connection block is connected to the first connection block when it is movable. A signal transmitter is detachably connected to the surface of the shell, and a control box is detachably connected to one side of the base.

[0018] A method for rapidly measuring the volume of an asymmetric container structure comprises the following steps:

[0019] Step 1: When measuring, the controller measures the liquid volume in the fermentation tank through the liquid level meter and flow meter, and obtains the pre-calibration value through the liquid level meter. The pre-calibration value is the liquid level height input by the liquid level meter. Water is added to the container using the flow meter. The accumulated liquid volume of the flow meter is checked at each position where the composition of the components in the tank changes. The data is entered from the first to the most groups respectively from the least to the most. After each entry, click the corresponding record button;

[0020] Step 2: After completing all data, the system generates a two-point calibration algorithm for each adjacent two groups. The algorithm is: if the fourth group's signal value is less than the previous value and less than the fifth group's signal value, the calibration value is equal to ((fifth group standard value - fourth group standard value) / (fifth group signal value - fourth group signal value)) * (previous value - fourth group signal value) + fourth group standard value. The remaining group items are calculated using this algorithm.

[0021] Step 3: Connect the fermentation tank through the base. Place the fermentation tank on the base surface. Connect the base to the connecting plate. Fix the horizontal plate through the connecting plate. Connect the controller through the horizontal plate. An air intake pipe runs through the interior of the connecting plate. Connect one end of the air intake pipe to the interior of the fermentation tank.

[0022] Step 4: A liquid inlet pipe is connected to the top of the fermentation tank, and liquid is introduced into the fermentation tank through the liquid inlet pipe. A stirring shaft is detachably connected to the fermentation tank, and the inside of the fermentation tank is stirred by stirring blades detachably connected to the surface of the stirring shaft. The stirring process is assisted by a baffle and a filter.

[0023] Step 5: Multiple shells are connected inside the fermenter, and the shells are distributed in different areas of the inner wall of the fermenter. When the fermenter is stirred, water flows through the slots opened on the surface of the shells, that is, the water flow pushes the vertical plate to tilt, thereby tilting the second connecting block detachably connected to one end of the vertical plate. The vertical plate is connected to the inside of the slot via a rotating shaft, and the vertical plate is moved by the rotating shaft;

[0024] Step 6. A vertical block is fixedly connected to the top of the inner side of the slot, and the first connecting block is embedded and connected on both sides of the surface of the vertical plate. When the second connecting block is tilted, it will touch the first connecting block. When the first connecting block and the second connecting block are in contact, electricity will be supplied, and signals will be transmitted through the wires. The signals contacted at different positions will be transmitted to the outside world through the signal transmitter detachably connected to the surface of the shell.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. During measurement, the controller measures the liquid volume in the fermentation tank through the liquid level meter and flow meter, and obtains the pre-calibration value through the liquid level meter. The pre-calibration value is the liquid level height input by the liquid level meter. Water is added to the container using the flow meter, and the accumulated liquid volume of the flow meter is checked at the position where the composition of each tank component changes. The data is entered from the first to the most groups from least to most. After each entry, the corresponding record button is clicked. After completing all the data, the system generates a 2-point correction algorithm in each adjacent 2 groups, that is, the fourth group signal recording value < the previous value ≤ the fifth group signal recording value, the post-calibration value = ((fifth group standard value - fourth group standard value) / (fifth group signal value - fourth group signal value)) * (previous value - fourth group signal value) + fourth group standard value. The remaining group items are all calculated using this algorithm formula, so that the height can be directly converted into liquid volume or weight through a fixed formula. It is easy for operators to use and increases the convenience of the liquid level meter.

[0027] 2. Connect multiple shells inside the fermentation tank, and the shells are distributed in different areas of the inner wall of the fermentation tank. When the fermentation tank is stirred, water flows through the slots opened on the surface of the shells, that is, the water flow pushes the vertical plate to tilt, thereby tilting the second connecting block detachably connected to one end of the vertical plate. The vertical plate is connected to the inside of the slot through a rotating shaft, and the vertical plate is moved by the rotating shaft to facilitate the vertical plate to swing due to the water flow, thereby increasing the mobility. The vertical block is fixedly connected to the top of the inner side of the slot, and the first connecting block is embedded on both sides of the surface of the vertical plate. When the second connecting block tilts, it engages with the first connecting block. The first connecting block and the second connecting block are made of conductive material, so that they are energized when in contact, and the signal is transmitted through the wire. The signal transmitter detachably connected to the surface of the shell transmits the signal of the signal transmitter in contact at different positions to the outside world, so that the regional flow direction at different positions can be recorded, thereby increasing the overall detectability. Then, the fermentation tank is provided with a device for detecting the direction of the fluid in various parts thereof, so that when stirring in the tank body, the occurrence of uneven stirring caused by the appearance of four corners at a certain place is reduced, the product quality is improved, and the design defects at a certain place in the tank are easily detected.

[0045] A method for rapidly measuring the volume of an asymmetric container structure comprises the following steps:

[0046] Step 1: During measurement, the controller 503 measures the liquid volume in the fermentation tank 1 using the liquid level meter 11 and the flow meter 10. The pre-calibration value is obtained by the liquid level meter 11. The pre-calibration value is the liquid level height input by the liquid level meter 11. Water is added to the container using the flow meter 10. The accumulated liquid volume of the flow meter 10 is checked at each position where the composition of the components in the tank changes. The data is entered into the first to the most groups from least to most, and the corresponding record button is clicked after each entry.

[0047] Step 2: After completing all data, the system generates a two-point calibration algorithm for each adjacent two groups. The algorithm is: if the fourth group's signal value is less than the previous value and less than the fifth group's signal value, the calibration value is equal to ((fifth group standard value - fourth group standard value) / (fifth group signal value - fourth group signal value)) * (previous value - fourth group signal value) + fourth group standard value. The remaining group items are calculated using this algorithm.

[0048] Step 3: Connect the fermentation tank 1 through the base 2. Place the fermentation tank 1 on the surface of the base 2. Connect the base 2 to the connecting plate 501. Fix the horizontal plate 502 through the connecting plate 501. Connect the controller 503 through the horizontal plate 502. An air intake pipe 4 runs through the interior of the connecting plate 501. Connect one end of the air intake pipe 4 to the interior of the fermentation tank 1.

[0049] Step 4: A liquid inlet pipe 3 is connected to the top of the fermentation tank 1, and liquid is introduced into the fermentation tank 1 through the liquid inlet pipe 3. A stirring shaft 7 is detachably connected to the fermentation tank 1, and stirring blades 9 detachably connected to the surface of the stirring shaft 7 are used to stir the interior of the fermentation tank 1. The baffle 12 and the filter 8 play an auxiliary role in the stirring process;

[0050] Step 5: Multiple housings 1301 are connected inside the fermentation tank 1. The housings 1301 are distributed in different areas of the inner wall of the fermentation tank 1. When stirring inside the fermentation tank 1, water flows through the slots 1302 opened on the surface of the housings 1301. That is, the water flow pushes the vertical plate 1306 to tilt, thereby tilting the second connecting block 1307 detachably connected to one end of the vertical plate 1306. The vertical plate 1306 is connected to the inside of the slot 1302 via the rotating shaft 1305, and the vertical plate 1306 is moved by the rotating shaft 1305.

[0051] Step six: A vertical block 1303 is fixedly connected to the top inner side of the slot 1302, and a first connecting block 1304 is embedded and connected on both sides of the surface of the vertical plate 1306. When the second connecting block 1307 is tilted, it will touch the first connecting block 1304. When the first connecting block 1304 and the second connecting block 1307 are in contact, electricity will be supplied, and signal transmission will be carried out through the wire 1308. The signal of contact at different positions will be transmitted to the outside world through the signal transmitter 1309 detachably connected to the surface of the shell 1301.

[0052] During measurement, the controller 503 measures the liquid volume in the fermentation tank 1 through the liquid level meter 11 and the flow meter 10, and obtains the pre-calibration value through the liquid level meter 11. The pre-calibration value is the liquid level height input by the liquid level meter 11. Water is added to the container using the flow meter 10. The liquid volume accumulated by the flow meter 10 is checked at each position where the composition of the components in the tank changes. The data is entered into the first to the most groups from least to most. After each entry, the corresponding record button is clicked. After completing all the data, the system generates a 2-point correction algorithm in each adjacent 2 groups, that is, the fourth group signal record value < the previous value ≤ the fifth group signal record value, and the post-calibration value = ((fifth group standard value - fourth group standard value) / (fifth group signal value - fourth group signal value))*(previous value - fourth group signal value)+fourth group standard value, the remaining groups are calculated using this algorithm formula, so that the height can be directly converted into liquid volume or weight through a fixed formula, which is convenient for operators to use and increases the convenience of the liquid level meter 11. Multiple shells 1301 are connected inside the fermentation tank 1, and the shells 1301 are distributed in different areas of the inner wall of the fermentation tank 1. When the fermentation tank 1 is stirred, the water flows through the grooves 1302 opened on the surface of the shells 1301, that is, the water flow pushes the vertical plate 1306 to tilt, thereby tilting the second connecting block 1307 detachably connected to one end of the vertical plate 1306. The vertical plate 1306 is connected to the inside of the groove 1302 through the rotating shaft 1305, and the vertical plate 1306 is moved by the rotating shaft 1305 to facilitate the vertical plate 1306 to swing through the water flow, thereby increasing the activity. , a vertical block 1303 is fixedly connected to the top of the inner side of the slot 1302, and a first connecting block 1304 is embedded on both sides of the surface of the vertical plate 1306. When the second connecting block 1307 is tilted, it touches the first connecting block 1304. The first connecting block 1304 and the second connecting block 1307 are made of conductive material, so that when they touch, they are energized and transmit signals through the wire 1308. The signal transmitter 1309 detachably connected to the surface of the shell 1301 transmits the signal of the signal transmitter 1309 in contact at different positions to the outside world, so that the flow direction of the area at different positions can be recorded, thereby increasing the overall detectability. Then, the fermentation tank 1 has a device for detecting the fluid direction of various parts inside it, thereby reducing the occurrence of uneven stirring due to the appearance of four corners in a certain place during stirring in the tank body, improving product quality, and easily detecting design defects in a certain place in the tank.
