Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil production technology, specifically to a quantity control device for adding amino acid ingredients in rapeseed oil production. Background Technology

[0002] In rapeseed oil production, adding amino acids to the oil system is a key process to enhance the nutritional value and functional properties of the oil. As a natural nutritional fortifier, amino acids can supplement the deficiency of essential amino acids in rapeseed oil, optimize the balance ratio of fatty acids and amino acids, and play a role in regulating interfacial activity during refining processes such as degumming and decolorization, thereby improving the separation efficiency of oil and impurities.

[0003] To facilitate faster and better dispersion of amino acids in rapeseed oil, factories typically add liquid amino acids. Liquid amino acids are usually viscous aqueous solutions, and the polar groups in their molecular structure give them strong adhesion to surfaces such as metals and plastics. Current technology generally uses a rotor flow meter to monitor the addition of liquid amino acids and a traditional method of direct delivery via plastic pipes. However, this type of equipment exhibits significant drawbacks when handling highly viscous liquids: the liquid amino acids form a stagnant film on the inner wall of the delivery pipe, resulting in an actual flow rate lower than the set value. Furthermore, as operating time increases, the adhesion layer gradually solidifies into a "gelatinous scale layer," further clogging the flow channel and causing an even greater discrepancy between the actual and set amount of amino acids added.

[0004] Therefore, there is an urgent need to design a quantity control device for adding amino acid ingredients in rapeseed oil production, in order to solve the technical problem in the existing technology that the amino acid solution has a high viscosity and is easy to adhere to the inside of the conveying pipe, resulting in a large deviation between the actual amount of amino acid added and the set amount. Utility Model Content

[0005] The present invention aims to provide a quantity control device for adding amino acid ingredients in rapeseed oil production, so as to solve the technical problem in the prior art that the amino acid solution has a high viscosity and is easy to adhere to the inside of the conveying pipe, resulting in a large deviation between the actual amount of amino acid added and the set amount of added.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] 1) A flow control device for adding amino acid ingredients in rapeseed oil production, characterized in that it includes a storage cylinder, a pushing member slidably fitted inside the storage cylinder, the pushing member dividing the storage cylinder from bottom to top into a liquid chamber and a gas chamber; multiple discharge nozzles are provided at the bottom of the storage cylinder, each discharge nozzle having a discharge hole in its center, the discharge hole communicating with the liquid chamber; an air hole is provided on the top wall of the storage cylinder, the air hole communicating with the gas chamber; an air pump is provided on one side of the storage cylinder, the air pump being connected to the air hole via a pipe, a volumetric flow meter being installed on the pipe; and a microprocessor is also included, the air pump and the volumetric flow meter being electrically connected to the microprocessor.

[0008] This invention features four discharge nozzles. The oil bottle is placed below the discharge nozzle of a storage cylinder filled with amino acid solution. A target addition amount is set in the microprocessor, and then the air pump is started and the exhaust mode is switched. Gas enters the gas chamber through a volumetric flow meter, increasing the pressure in the gas chamber. This pressure pushes the liquid chamber downwards, allowing the amino acid solution to be discharged from the discharge nozzle. During gas delivery, the volumetric flow meter monitors the gas injection volume in real time and uploads the data to the microprocessor. The value monitored by the volumetric flow meter is set as the measured value. The microprocessor compares the set value with the measured value. When the measured value equals the set value, it issues a command to shut down the air pump. Simultaneously, the microprocessor resets the measured value to zero upon issuing the command to shut down the air pump, preparing for the next monitoring. After the amino acid has been added to the oil bottle, the bottle with added amino acids is removed, and a new bottle without added amino acids is placed below the discharge nozzle. Then, the air pump is started to add amino acids to the new bottle without added amino acids.

[0009] This invention allows the amino acid solution to be directly extruded by a pusher, avoiding residue buildup caused by flowing through long pipes. It solves the technical problem in existing technologies where the high viscosity of the amino acid solution causes it to easily adhere to the conveying pipe, resulting in a large deviation between the actual and set dosage. Furthermore, the volumetric flow meter can be used to measure high-viscosity liquids with high accuracy, reducing errors; multiple nozzles allow for simultaneous amino acid addition to multiple oil bottles, increasing efficiency.

[0010] 2) The quantity control device for adding amino acid ingredients in rapeseed oil production as described in 1), wherein: a conveyor belt is provided under the storage cylinder, and a plurality of positioning sleeves for placing oil bottles are evenly spaced along the conveying direction of the conveyor belt, the distance between the centers of two adjacent positioning sleeves is the same as the distance between the centers of two adjacent discharge holes, and a stepper motor for driving the conveyor belt to perform conveying motion is provided on the side of the conveyor belt along its conveying direction.

[0011] When installing the conveyor belt, it must be adjusted so that the discharge nozzle is vertically aligned with the center of the positioning sleeve. Place the oil bottle into the positioning sleeve and start the stepper motor. The conveyor belt will move the oil bottle periodically and step-by-step according to the set step distance. The step distance refers to the linear distance the conveyor belt moves for each pulse signal received by the stepper motor. The stepper motor receives a fixed number of pulse signals each cycle. By setting the conveyor belt to move exactly the distance of the four positioning sleeves each cycle, each time the conveyor belt stops, four new oil bottles without added amino acids are aligned with the four discharge nozzles. When the oil bottle stops directly below the discharge nozzle, start the air pump, and the discharge nozzle begins the filling process. The spacing between two adjacent positioning sleeves matches the spacing between two adjacent discharge holes in a 1:1 ratio, ensuring one nozzle per bottle positioning sleeve. Hard positioning of the oil bottle prevents leakage caused by bottle movement. The cooperation between the conveyor belt and the positioning sleeves supports continuous production and improves production efficiency.

[0012] 3) The quantity control device for adding amino acid ingredients in rapeseed oil production as described in 2), wherein: a photoelectric sensor is provided on the side of the conveyor belt along its conveying direction, the photoelectric sensor is electrically connected to the control system, and the control system is electrically connected to the air pump.

[0013] When the oil bottle is delivered to the photoelectric sensor, the infrared light emitted by the photoelectric sensor is reflected back to the photoelectric sensor and sends a signal to the control system. The control system then controls the air pump to start. With this structure, when the oil bottle stops directly below the discharge nozzle, the dispensing action of the discharge nozzle can be triggered synchronously, making the production process more automated.

[0014] 4) The quantity control device for adding amino acid ingredients in rapeseed oil production according to 3), wherein: the control system includes a signal processing module, a counting control module and a start control module, the signal processing module is connected to the photoelectric sensor, the counting control module is connected to the signal processing module, and the counting control module and the air pump are both connected to the start control module.

[0015] The signal processing module is connected to the photoelectric sensor, which receives electrical signals and converts them into counting pulses. The counting control module is connected to the signal processing module, which accumulates the number of counting pulses and outputs a start control signal when the count reaches a preset value of 4. The start control module is connected to the counting control module and the air pump, which responds to the start control signal by turning on the air pump to add amino acids. With this structure, the air pump can automatically turn on and off during the amino acid addition process, that is, it can automatically switch the adding and stopping actions of the dispensing nozzle, which can basically achieve automation without manual intervention and save labor costs.

[0016] 5) The quantity control device for adding amino acid ingredients in rapeseed oil production as described in 1), wherein: the outer wall of the storage cylinder is provided with multiple scale lines, and the multiple scale lines are evenly spaced along the sliding direction of the pusher.

[0017] The storage cylinder of this invention is made of transparent material, allowing manual observation of the scale value corresponding to the position of the pushing component, which can be cross-verified with data from a volumetric flow meter. This mutual verification between the mechanical scale and the volumetric flow meter improves system reliability.

[0018] 6) The quantity control device for adding amino acid ingredients in rapeseed oil production according to 1), wherein: the pushing member includes a bottom plate, the periphery of the bottom plate is slidably engaged with the inner wall of the storage cylinder, a surrounding plate is fixedly provided on the bottom plate, the bottom edge of the surrounding plate is fixedly connected to the outer periphery of the bottom plate, and the outer periphery of the surrounding plate is completely flush with the periphery of the bottom plate; the bottom plate is made of soft rubber, and the surrounding plate is made of hard rubber.

[0019] The outer sheath (hard rubber) provides structural support and maintains the vertical movement trajectory; the inner sheath (soft rubber) can deform and fill the tiny uneven areas of the cylinder wall, completely scrape the liquid off the cylinder wall, and also better adapt to air pressure, extending its service life.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention features four discharge nozzles. The oil bottle is placed below the discharge nozzle of a storage cylinder filled with amino acid solution. A target addition amount is set in the microprocessor, and then the air pump is started and the exhaust mode is switched. Gas enters the gas chamber through a volumetric flow meter, increasing the pressure in the gas chamber. This pressure pushes the liquid chamber downwards, allowing the amino acid solution to be discharged from the discharge nozzle. During gas delivery, the volumetric flow meter monitors the gas injection volume in real time and uploads the data to the microprocessor. The value monitored by the volumetric flow meter is set as the measured value. The microprocessor compares the set value with the measured value. When the measured value equals the set value, it issues a command to shut down the air pump. Simultaneously, the microprocessor resets the measured value to zero upon issuing the command to shut down the air pump, preparing for the next monitoring. After the amino acid has been added to the oil bottle, the bottle with added amino acids is removed, and a new bottle without added amino acids is placed below the discharge nozzle. Then, the air pump is started to add amino acids to the new bottle without added amino acids.

[0022] This invention allows the amino acid solution to be directly extruded by a pusher, avoiding residue buildup caused by flowing through long pipes. It solves the technical problem in existing technologies where the high viscosity of the amino acid solution causes it to easily adhere to the conveying pipe, resulting in a large deviation between the actual and set dosage. Furthermore, the volumetric flow meter can be used to measure high-viscosity liquids with high accuracy, reducing errors; multiple nozzles allow for simultaneous amino acid addition to multiple oil bottles, increasing efficiency.

[0033] Please see Figures 1-3 This utility model relates to a quantity control device for adding amino acid ingredients in rapeseed oil production. It includes a storage cylinder 1, with a slidingly fitted pusher 2 inside the storage cylinder 1, dividing the storage cylinder 1 from bottom to top into a liquid chamber and a gas chamber. Multiple discharge nozzles 3 are located at the bottom of the storage cylinder 1, each with a discharge hole in the center, connected to the liquid chamber. Air holes are located on the top wall of the storage cylinder 1, connected to the gas chamber. An air pump is located on one side of the storage cylinder 1, connected to the air holes via a pipe 4, on which a volumetric flow meter is installed. The device also includes a microprocessor, with the air pump and volumetric flow meter electrically connected to it. In this embodiment, there are four discharge nozzles 3. The air pump can be a TPN23-2A1, the volumetric flow meter can be an LC13-P25, and the microprocessor can be an STM32F103C8T6.

[0034] In this utility model, the initial position of the pusher 2 in the quantity control device for adding amino acid ingredients in rapeseed oil production is to abut against the bottom wall of the storage cylinder 1. Before adding amino acid ingredients to the oil bottle 6, the storage cylinder 1 needs to be filled with amino acid solution. The operation steps are as follows: First, place the container containing amino acid solution below the storage cylinder 1, and immerse the outlet 3 below the liquid surface of the container filled with amino acid solution. Then, turn on the air pump and switch the suction mode. The air pump extracts the gas from the gas chamber, the pressure in the gas chamber decreases, the pusher 2 moves upward, and the amino acid solution is sucked into the liquid chamber through the outlet 3. When the pusher 2 abuts against the upper wall of the storage cylinder 1, the storage cylinder 1 is filled with amino acid solution, and the air pump can be turned off at this time.

[0035] After the amino acid solution is loaded, oil bottle 6 is placed below the outlet 3 of the storage cylinder 1 filled with amino acid solution. The target addition amount is set in the microprocessor, and then the air pump is started and the exhaust mode is switched. Gas enters the gas chamber through the volumetric flow meter, increasing the pressure in the gas chamber. The pusher 2 then forces the liquid chamber downwards, allowing the amino acid solution to be discharged from the outlet 3. During gas delivery, the volumetric flow meter monitors the gas injection volume in real time and uploads the data to the microprocessor. The value monitored by the volumetric flow meter is set as the measured value. The microprocessor compares the set value with the measured value. When the measured value equals the set value, it issues a command to shut down the air pump. Simultaneously, the microprocessor is set to reset the measured value to zero at the same time as issuing the command to shut down the air pump, in preparation for the next monitoring. After amino acid is added to oil bottle 6, the bottle with added amino acids is removed, and a new bottle without added amino acids is placed below the outlet 3. Then, the air pump is started to add amino acids to the new bottle without added amino acids.

[0036] In this invention, the amino acid solution is directly extruded by the pusher 2, avoiding residue caused by flowing through a long conveying pipe. This solves the technical problem in the prior art where the high viscosity of the amino acid solution easily adheres to the inside of the conveying pipe, resulting in a large deviation between the actual and set amount of amino acid added. Furthermore, the volumetric flow meter can be used to measure high-viscosity liquids with high measurement accuracy, reducing errors; multiple discharge nozzles 3 can simultaneously add amino acids to multiple oil bottles 6, resulting in higher efficiency.

[0037] In this embodiment: a conveyor belt 5 is provided under the storage cylinder, and multiple positioning sleeves 7 for placing oil bottles 6 are evenly spaced along the conveying direction of the conveyor belt 5. The distance between the centers of two adjacent positioning sleeves 7 is the same as the distance between the centers of two adjacent discharge holes. A stepper motor for driving the conveyor belt 5 to perform conveying motion is provided on one side of the conveyor belt 5. In this embodiment, the stepper motor model can be 57HS09.

[0038] When installing the conveyor belt 5, it needs to be adjusted so that the discharge nozzle 3 is vertically aligned with the center of the positioning sleeve 7. Place the oil bottle 6 into the positioning sleeve 7 and start the stepper motor. The conveyor belt 5 will move the oil bottle 6 periodically and stepwise according to the set step distance. The step distance refers to the straight-line distance the conveyor belt 5 moves for each pulse signal received by the stepper motor. The stepper motor receives a fixed number of pulse signals each cycle. By setting the conveyor belt 5 so that the distance moved by each cycle is exactly the distance of the four positioning sleeves 7, that is, each time the conveyor belt 5 stops, four new oil bottles 6 without added amino acids are aligned with the four discharge nozzles 3. When the oil bottle 6 stops directly below the discharge nozzle 3, start the air pump, and the discharge nozzle 3 begins the filling action. The spacing between two adjacent positioning sleeves 7 matches the spacing between two adjacent discharge holes in a 1:1 ratio, enabling one nozzle to one bottle positioning sleeve 7; hard positioning of the oil bottle 6 prevents leakage caused by bottle shaking; the cooperation between the conveyor belt 5 and the positioning sleeves 7 supports continuous production and improves production efficiency.

The photoelectric sensor 8 is electrically connected to the control system, and the control system is electrically connected to the air pump. The photoelectric sensor 8 can be model E3F-DS10C4.

[0040] When the oil bottle 6 is delivered to the photoelectric sensor 8, the infrared light emitted by the photoelectric sensor 8 is reflected back to the photoelectric sensor 8 and sends a signal to the control system. The control system controls the air pump to start. With this structure, when the oil bottle 6 stops directly below the discharge nozzle 3, the dispensing action of the discharge nozzle 3 can be triggered synchronously, making the production process more automated.

[0041] In this embodiment, the control system includes a signal processing module, a counting control module, and a start control module. The signal processing module is connected to the photoelectric sensor 8, the counting control module is connected to the signal processing module, and both the counting control module and the air pump are connected to the start control module.

The counting control module is connected to the signal processing module, which accumulates the number of counting pulses and outputs a start control signal when the count reaches a preset value of 4. The start control module is connected to the counting control module and the air pump, which responds to the start control signal to turn on the air pump and add amino acids. With this structure, the air pump can automatically turn on and off during the addition of amino acids, that is, it can automatically switch the adding and stopping actions of the dispensing nozzle 3, which can basically realize automation without manual intervention and save labor costs.

[0043] In this embodiment, the outer wall of the storage cylinder 1 is provided with multiple scale lines, which are evenly spaced along the sliding direction of the pusher 2.
