Description

Technical Field

[0001] This invention relates to the field of packaging technology, specifically to an intelligent integrated device for transferring and packaging biomass fuel. Background Technology

[0002] Biomass fuel, an environmentally friendly new energy source processed from agricultural and forestry waste such as straw, rice straw, rice husks, peanut shells, and corn cobs, occupies an important position in the energy supply system due to its renewable and low-pollution characteristics. In the large-scale production process of biomass fuel, transfer and packaging are crucial links in ensuring product storage, transportation, and end-use applications, directly affecting the product's commercial value and utilization efficiency.

[0003] Existing biomass fuel baling equipment mostly adopts the traditional conveying-filling-packaging model. Its core structure typically only includes basic components such as a conveying mechanism, hopper, and baling rack. Its function is concentrated on simple material transfer and quantitative packaging, lacking the ability to finely process the integrity of the material. In actual production, biomass fuel (especially in cylindrical, pellet, or flake form) inevitably produces powdery debris and broken particles due to collision and compression during processing and transportation. These substandard materials mix with intact materials and directly enter the baling stage through existing equipment, leading to the following problems:

[0004] On the one hand, the packaged materials contain a large amount of powdery and broken materials, which not only reduces the overall purity and combustion stability of the product, but may also cause secondary breakage due to vibration during storage and transportation, further affecting the end-user's experience. On the other hand, powdery and broken materials with recycling value cannot be effectively separated, either packaged together with intact materials or scattered and wasted due to untimely separation, resulting in low resource utilization and failing to meet the requirements of energy-saving and environmentally friendly industrial development. Summary of the Invention

[0005] This invention provides an intelligent integrated biomass fuel transfer and packaging device, capable of packaging high-quality materials.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0007] An intelligent biomass fuel transfer and baling integrated device includes: a baling frame and a fence installed on the baling frame, a ladder fixed to the outside of the baling frame, a support frame fixed above the baling frame, and a feeding hopper fixed to the support frame; and further includes:

[0008] The material limiting hopper is fixed above the material discharging hopper; the material dispersing pipe is fixed above the material limiting hopper; the negative pressure separator is fixed to the material dispersing pipe and the mounting plate, used to suck up broken materials; the material discharging component is fixed to the material discharging hopper; the material discharging vibrator is fixed to both sides of the material discharging hopper; the controller is fixed to the packing frame; the dispersing vibrator is fixed to the material dispersing pipe; the vibrating crossbar is fixed to the dispersing vibrator and located inside the material dispersing pipe; and the mounting plate is fixed to the packing frame.

[0012] Furthermore, the negative pressure separator also includes:

[0013] The first intercepting net is fixed to the air inlet of the first slag separating pipe; the first slag separating flange is fixed to the air outlet of the first slag separating pipe; the second intercepting net is fixed to the air inlet of the second slag separating pipe; the second slag separating flange is fixed to the air outlet of the second slag separating pipe; the third intercepting net is fixed to the air inlet of the third slag separating pipe; the third slag separating flange is fixed to the air outlet of the third slag separating pipe.

[0014] Furthermore, the negative pressure separator also includes:

[0015] The drive motor is fixed on the first, second, and third slag distribution pipes; the valve plate is rotatably disposed inside the first, second, and third slag distribution pipes; the first bevel gear set has its input end fixed on the drive motor shaft and its output end fixed on the valve plate shaft.

[0016] Furthermore, the negative pressure separator also includes:

[0018] Furthermore, the unloading component includes:

[0019] The motor base plate is fixed on the feeding hopper; the feeding motor has its base fixed on the motor base plate; the drive shaft is rotatably mounted on the motor base plate; the second bevel gear set has an input bevel gear fixed on the feeding motor and an output bevel gear fixed above the drive shaft; the cone column is fixed on the drive shaft; the scraper plate is fixed on the cone column; and the spiral blade is fixed on the drive shaft and fixedly connected to the bottom of the cone column.

[0022] Furthermore, the controller processing steps are as follows:

[0023] Step S1: Receive pressure signals from the first differential pressure sensor, the second differential pressure sensor, the third differential pressure sensor, and the vacuum pressure sensor in real time, and synchronously acquire the operating status signal of the conveyor line to establish a multi-source signal acquisition matrix;

[0024] Step S2: Based on the multi-source signal acquisition matrix in step S1, the effective control parameters are separated by feature extraction algorithm, and the raw data is converted into standardized control commands;

[0025] Step S3: Control the start and stop of the feeding motor, high-pressure centrifugal fan and drive motor according to the standardized control instructions in step S2;

[0026] Step S4: Match the frequency and interval of the feeding vibrator and the dispersing vibrator according to the material conveying rhythm to form a basic linkage control closed loop, ensuring that the material is dispersed and then separated and falls.

[0027] Furthermore, the controller processing steps are as follows:

[0028] Step S5: Collect real-time pressure data of the vacuum generating U-tube using the second differential pressure sensor and the vacuum pressure sensor;

[0029] Step S6: Use the real-time pressure data from step S5 to generate the power regulation coefficient of the high-pressure centrifugal fan using a PID algorithm;

[0030] Step S7: Adjust the output of the high-pressure centrifugal fan according to the power adjustment coefficient in step S6 to achieve vacuum generation and negative pressure regulation in the U-tube;

[0031] Step S8: Receive the pressure data of the first and second separation tubes fed back by the first differential pressure sensor, and drive the corresponding drive motor to operate in combination with the result of step S7;

[0032] Step S9: The driving force is transmitted to the valve plate through the first bevel gear set. The opening and closing degree of the valve plate in the first slag separation pipe, the second slag separation pipe and the third slag separation pipe are adjusted to achieve dynamic matching of negative pressure and slag separation airflow, and to accurately separate powdery and broken materials.

[0033] Furthermore, the controller processing steps are as follows:

[0034] Step S10: Integrate the feed motor speed, the frequency of the dispersed vibrator, the pressure of the third differential pressure sensor, and the weighing signal of the conveyor line to generate a real-time working condition feature vector;

[0035] Step S11 identifies the feeding speed trend based on the real-time working condition feature vector of step S10, adjusts the intensity of the dispersed vibrator, and synchronously sends a coordination signal to the controller.

[0036] Step S12: After receiving the coordination signal from step S11, the controller adjusts the negative pressure adsorption force of the first separation tube and the second separation tube to achieve linkage adaptation of material dispersion and separation.

[0037] Step S13: When the weighing signal reaches the preset threshold, a coordinated action is triggered to stop the feeding motor and release the hydraulic rod driving the clamping plate.

[0038] Step S14: During the execution of step S13, record each parameter, sensor data and action sequence, and generate a traceable log with timestamps to ensure the integrity of the bagged materials.

[0039] The above-described solution of the present invention has at least the following beneficial effects:

[0040] This invention generates a directional negative pressure field through a negative pressure separator, which, in conjunction with a dispersing vibrator, drives a vibrating crossbar to disperse the material. This ensures that powdery and broken materials are fully exposed to the adsorption areas of the first and second separation pipes, while intact columnar materials fall into the material bag under their own weight through the negative pressure zone. This effectively prevents broken materials from being mixed in, significantly improving the integrity and quality of the material entering the bag. Through the airflow guidance of the vacuum-generated U-tube and the graded interception design of the first, second, and third slag separation pipes, combined with the precise control of the valve plate, powdery materials and broken materials of different specifications enter their respective pipes. They are then classified and recycled through the slag block pipe and each slag separation flange, reducing resource waste and facilitating subsequent reprocessing. The controller's coordinated control further optimizes the separation rhythm by dynamically adjusting the negative pressure intensity and vibration frequency to ensure a stable and efficient separation process, ultimately achieving the dual benefits of high-quality bagging of intact materials and precise recovery of broken materials.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0056] like Figures 1 to 10 As shown, an embodiment of the present invention provides an intelligent biomass fuel transfer and packaging integrated device, including: a packaging frame 1 and a fence 2 set on the packaging frame 1, a ladder 3 fixed to the outside of the packaging frame 1, a support frame 4 fixed above the packaging frame 1, and a feeding hopper 5 fixed to the support frame 4, and further including: a limiting hopper 6 fixed above the feeding hopper 5; a dispersing pipe 7 fixed above the limiting hopper 6; a negative pressure separator 8 fixed on the dispersing pipe 7 and a mounting plate 14 for absorbing broken materials; a feeding component 9 fixed on the feeding hopper 5; a feeding vibrator 10 fixed on both sides of the feeding hopper 5; a controller 11 fixed on the packaging frame 1; a dispersing vibrator 12 fixed on the dispersing pipe 7; a vibrating crossbar 13 fixed on the dispersing vibrator 12 and located inside the dispersing pipe 7; and a mounting plate 14 fixed on the packaging frame 1.

[0057] A vacuum generating U-tube 801 is fixed to the mounting plate 14; a first separation tube 802 extends one end into the vacuum generating U-tube 801 and the other end is fixed to the material distribution pipe 7; a second separation tube 803 is fixed one end to the first separation tube 802 and the other end to the material distribution pipe 7; a high-pressure centrifugal fan 804 is fixed above the packing rack 1; an airflow pipe 805 is fixed one end to the output end of the high-pressure centrifugal fan 804 and the other end extends into the vacuum generating U-tube 801; and a first slag separating pipe 806... The first slag distribution pipe 806 is fixed on the end of the vacuum generating U-tube 801 away from the gas flow pipe 805; the second slag distribution pipe 807 is fixed on the end of the vacuum generating U-tube 801 away from the gas flow pipe 805 and is located directly below the first slag distribution pipe 806; the third slag distribution pipe 808 is fixed on the end of the vacuum generating U-tube 801 away from the gas flow pipe 805 and is located directly below the second slag distribution pipe 807; the slag block pipe 809 is fixed on the end of the vacuum generating U-tube 801 away from the gas flow pipe 805 and is located directly below the third slag distribution pipe 808.

[0058] Specifically, the packing rack 1 serves as the main frame of the device, with the top of it supported by the support frame 4 to support the unloading hopper 5. The outer fence 2 and the ladder 3 respectively provide safety protection and maintenance access. The vibrating crossbar 13 driven by the dispersing vibrator 12 assists in dispersing the material. The controller 11 coordinates the operation of each component to achieve integrated operation of transfer, separation and packing.

[0059] In a preferred embodiment of the present invention, the negative pressure separating component 8 further includes: a separating flange 8010, fixed on the end of the first separating pipe 802 and the second separating pipe 803 away from the vacuum generating U-tube 801; a hollow cover 8011, bolted to the separating flange 8010; a limiting ring 8012, fixed inside the first separating pipe 802 and the second separating pipe 803; a filter plate 8013, fixed inside the first separating pipe 802 and the second separating pipe 803, and located between the hollow cover 8011 and the limiting ring 8012; and a material limiting orifice plate 8014, fixed inside the first separating pipe 802 and the second separating pipe 803, and located at the junction of the first separating pipe 802 and the second separating pipe 803 and the material dispersing pipe 7.

[0060] The negative pressure separation component 8 also includes: a first intercepting net 8015, fixed on the air inlet of the first slag separating pipe 806; a first slag separating flange 8016, fixed on the air outlet of the first slag separating pipe 806; a second intercepting net 8017, fixed on the air inlet of the second slag separating pipe 807; a second slag separating flange 8018, fixed on the air outlet of the second slag separating pipe 807; a third intercepting net 8019, fixed on the air inlet of the third slag separating pipe 808; and a third slag separating flange 8020, fixed on the air outlet of the third slag separating pipe 808.

[0061] The negative pressure separator 8 also includes: a drive motor 8021, fixed on the first slag separating pipe 806, the second slag separating pipe 807 and the third slag separating pipe 808; a valve plate 8022, rotatably disposed inside the first slag separating pipe 806, the second slag separating pipe 807 and the third slag separating pipe 808; and a first bevel gear set 8023, with its input end fixed on the shaft of the drive motor 8021 and its output end fixed on the valve shaft of the valve plate 8022.

[0062] The negative pressure separation component 8 also includes: a first differential pressure sensor 8024, fixed on the first separation tube 802 and the second separation tube 803; a second differential pressure sensor 8025, fixed on the vacuum generating U-tube 801; a third differential pressure sensor 8026, fixed on the first slag separating tube 806, the second slag separating tube 807 and the third slag separating tube 808; and a vacuum pressure sensor 8027, fixed below the vacuum generating U-tube 801.

[0063] Specifically, the separation flange 8010 and the hollow cover 8011 work together to achieve a detachable connection between the first separation tube 802 and the second separation tube 803, and the internal limiting ring 8012 fixes the filter plate 8013 to intercept large particulate impurities.

[0064] In a preferred embodiment of the present invention, the unloading component 9 includes: a motor base plate 901, fixed on the unloading hopper 5; an unloading motor 902, the base of which is fixed on the motor base plate 901; a transmission shaft 903, rotatably mounted on the motor base plate 901; a second bevel gear set 904, the input bevel gear fixed on the unloading motor 902, and the output bevel gear fixed above the transmission shaft 903; a cone column 905, fixed on the transmission shaft 903; a scraper plate 906, fixed on the cone column 905; and a spiral blade 907, fixed on the transmission shaft 903 and fixedly connected to the lower part of the cone column 905.

[0065] The unloading component 9 includes: a side support plate 908, fixed on the mounting plate 14; an electric telescopic rod 909, with its non-telescopic end fixed on the side support plate 908; a bag support plate 9010, fixed on the electric telescopic rod 909; a hydraulic rod 9011, with its non-telescopic end fixed on the side support plate 908; and a clamping plate 9012, fixed on the hydraulic rod 9011.

[0066] Specifically, the motor base plate 901 provides fixed support for the feeding motor 902. The feeding motor 902 drives the transmission shaft 903 to rotate through the second bevel gear set 904. The conical column 905 on the transmission shaft 903, together with the scraper plate 906, rotates along the inner wall of the feeding hopper 5 to prevent material accumulation and blockage. The spiral blade 907 below realizes stable quantitative conveying of materials. The side support plate 908 serves as the load-bearing base. The electric telescopic rod 909 drives the bag support plate 9010 to adjust the height to adapt to different specifications of material bags. The hydraulic rod 9011 drives the clamping plate 9012 to cooperate with the bag support plate 9010 to fix the bag opening, ensuring the stability of the bag when the material falls, forming a continuous operation link of "conveying-bagging".

[0067] Working principle: The baling rack 1 is set up on the conveyor line. When baling is being carried out, the conveyor line will stop running. After baling is completed and sealed, the conveyor line will transport the material bag to the next stage. The feeding hopper 5 and the limiting hopper 6 contain columnar particles. The columnar particles are made from straw, rice straw, rice husks, peanut shells, corn cobs, camellia shells, cottonseed husks, sawdust, waste wood and "three residues" through processing. They belong to columnar environmentally friendly new energy. The form is not limited to columnar, but can also be granular or flake.

[0068] When the feeding motor 902 is started, its rotation will drive the second bevel gear set 904 to rotate, which in turn drives the transmission shaft 903 to rotate. The rotation of the transmission shaft 903 will drive the cone column 905, the scraper 906, and the spiral blade 907 to rotate. The scraper 906 will rotate along the inner wall of the limiting hopper 6 to avoid material blockage. The rotation of the spiral blade 907 can stably and quantitatively transport the material in the limiting hopper 6 to the dispensing pipe 7, and then the material will be discharged from the dispensing pipe 7.

[0069] The worker folds the opening of the material bag outwards and places the folded edge onto the bag support plate 9010. The electric telescopic rod 909 is activated, allowing the position of the bag support plate 9010 to be adjusted according to different bag sizes. Then, the hydraulic rod 9011 is activated, extending and causing the clamping plate 9012 to move towards the bag support plate 9010, thus pressing down on the edge of the material bag. Material is output from the material distribution pipe 7. Using the built-in weighing function on the conveyor belt, the spiral blade 907 stops rotating when the material reaches the preset weight.

[0070] During production or transportation, columnar particles inevitably break. The broken columnar particles enter the material bag through the dispensing pipe 7, which reduces the quality of the material in the material bag. Therefore, it is necessary to start the high-pressure centrifugal fan 804 for separation. The high-pressure centrifugal fan 804 draws in outside air, filters it, and forms a high-speed airflow. The airflow enters the airflow pipe 805 and then enters the vacuum generating U-tube 801. At the same time, the pressure difference between the vacuum generating U-tube 801 and the outside is detected by the second differential pressure sensor 8025, and the negative pressure value at the junction of the vacuum generating U-tube 801 and the airflow pipe 805 is detected by the vacuum pressure sensor 8027 to see if the negative pressure value has reached the preset state.

[0071] The first separation tube 802 and the second separation tube 803 are connected to the negative pressure area of ​​the vacuum generating tube 801, so that negative pressure is generated inside the first separation tube 802 and the second separation tube 803. The first differential pressure sensor 8024 detects whether the pressure difference between the first separation tube 802 and the second separation tube 803 and the outside world reaches a preset state. The first separation tube 802 and the second separation tube 803 are connected to the material dispensing tube 7. The negative pressure inside the first separation tube 802 and the second separation tube 803 can be used to extract powdery or broken columnar particles.

[0072] The interior of the first separation pipe 802 and the second separation pipe 803 is a negative pressure area. Outside air is drawn in through the filter plate 8013. The separated airflow drawn in from the outside passes through two areas at the junction of the first separation pipe 802 and the second separation pipe 803 and the material distribution pipe 7, bringing the powdery material and broken material from the material distribution pipe 7 into the first separation pipe 802 and the second separation pipe 803.

[0073] By controlling the rotation speed of the feeding motor 902, the feeding speed of the spiral blade 907 can be controlled; when the dispersing vibrator 12 is started, the vibration of the dispersing vibrator 12 drives the vibration cross bar 13 to vibrate, and when the columnar material is output from the spiral blade 907, it is dispersed by the vibration of the vibration cross bar 13.

[0074] The negative pressure in the first separation tube 802 and the second separation tube 803 will absorb powdery or broken columnar particles. Particles with higher integrity will pass through the negative pressure area by their own weight, while powdery and broken materials will be carried away by the two areas at the junction of the first separation tube 802 and the second separation tube 803 and the bulk material tube 7, and enter the vacuum generating U tube 801, and then enter the other end along the vacuum generating U tube 801.

[0075] The drive motor 8021 is started, and its rotation drives the first bevel gear set 8023 to rotate, which in turn drives the valve plate 8022 to rotate. The rotation of the drive motor 8021 controls the opening and closing of the valve plate 8022 in the first slag distribution pipe 806, the second slag distribution pipe 807, and the third slag distribution pipe 808, thereby controlling the airflow and allowing powdery materials to enter these pipes. Larger, broken materials fall into the slag block pipe by their own weight. Inside 809; the first slag distribution pipe 806, the second slag distribution pipe 807, and the third slag distribution pipe 808 are connected to external pipelines through the first slag distribution flange 8016, the second slag distribution flange 8018, and the third slag distribution flange 8020 to realize the recovery of powdery materials; the slag block pipe 809 realizes the recovery of broken materials by connecting to external flanges; the first intercepting net 8015, the second intercepting net 8017, and the third intercepting net 8019 on the first slag distribution pipe 806, the second slag distribution pipe 807, and the third slag distribution pipe 808 can restrict broken materials from entering the slag distribution pipes.

[0076] After the bulk material pipe 7 sucks up powdery and broken materials through the negative pressure, the columnar material output from the bulk material pipe 7 is relatively intact. Then, the columnar material is put into the material bag to ensure the quality of the columnar object in the material bag.

[0077] like Figures 10 to 12 As shown, an embodiment of the present invention provides an intelligent biomass fuel transfer and packaging integrated device, and the controller 11 processes the following steps:

[0078] Step S1: Receive pressure signals from the first differential pressure sensor 8024, the second differential pressure sensor 8025, the third differential pressure sensor 8026, and the vacuum pressure sensor 8027 in real time, synchronously acquire the operating status signal of the conveyor line, and establish a multi-source signal acquisition matrix.

[0079] By employing the steps described in S1 above, the controller 11 receives, in real time, pressure difference signals of 10-30 kPa (reflecting the adsorption force of the two separation pipes on the material in the bulk material pipe 7) collected by the first differential pressure sensor 8024 (installed on the inner wall of the first separation pipe 802 and the second separation pipe 803), pressure difference signals of 15-40 kPa (reflecting the negative pressure intensity in the vacuum generating U-tube 801) collected by the second differential pressure sensor 8025 (installed on the outer wall of the vacuum generating U-tube 801), pressure difference signals of 5-20 kPa (reflecting the ability of the airflow to carry material in the slag separating pipes) collected by the third differential pressure sensor 8026 (installed at the inlet of the first slag separating pipe 806, the second slag separating pipe 807, and the third slag separating pipe 808), and vacuum pressure sensor via its built-in interface. The -50 to -10 kPa absolute pressure signal (directly reflecting the negative pressure reference inside the vacuum generating U-tube 801) is collected by device 8027 (installed at the bottom of the vacuum generating U-tube 801); at the same time, a status signal of 0.5 to 2 m / s (running) or 0 (stopped) is obtained through the conveyor line status sensor (to determine whether the packaging process needs to be started); these signals are collected synchronously at a frequency of 50 times per second and integrated into a multi-source signal matrix in the format of "timestamp + sensor type + signal value", such as "16:20:30.123 + first differential pressure sensor + 20 kPa (adsorption force of first separation tube 802 meets the standard); 16:20:30.123 + conveyor line status + 1 m / s (ready to receive material bag)", to provide data support for subsequent separation actions.

[0080] Step S2: Based on the multi-source signal acquisition matrix in step S1, the effective control parameters are separated by feature extraction algorithm, and the raw data is converted into standardized control commands.

[0081] By employing the multi-source signal acquisition matrix based on S1 in step S2 above, the controller 11 uses a feature extraction algorithm to filter effective parameters, such as the 20kPa negative pressure value inside the first separation tube 802 (sufficient to adsorb powdery materials) and the "running" status of the conveyor line (material feeding can be started); then, the data is converted through normalization processing, for example, (20-10) ÷ (30-10) = 0.5 (the standardized value of the negative pressure in the first separation tube 802, reflecting moderate adsorption force), and the conveyor line status "1" remains unchanged; finally, according to the preset logic (the material feeding is started when the conveyor line is running and the negative pressure in the separation tube is ≥15kPa), a standardized instruction of "feeding motor 902 + start + 1500r / min" is generated (ensuring that the material can be effectively separated after entering the bulk material pipe 7).

[0082] Step S3: Control the start and stop of the feeding motor 902, the high-pressure centrifugal fan 804 and the drive motor 8021 according to the standardized control instructions in step S2.

[0083] By adopting the above steps S3, the controller 11 starts the feeding motor 902 through the relay output according to the standardized instructions of S2. The rotating shaft of the feeding motor 902 drives the transmission shaft 903 and the spiral blade 907 to rotate through the second bevel gear set 904 (to start pushing the columnar material in the limiting hopper 6 to the bulk material pipe 7), and controls the speed of 1500r / min with PWM signal (to control the falling speed of the material); the power supply frequency of the high-pressure centrifugal fan 804 is adjusted to 50Hz and started. The high-speed airflow generated by the high-pressure centrifugal fan 804 rushes into the vacuum generating U pipe 801 through the airflow pipe 805, forming a negative pressure in the vacuum generating U pipe 801 (to provide power for the separation pipe to adsorb broken materials); the drive motor 8021 is driven to run through the servo driver (to prepare to adjust the slag separation pipe valve plate); the high-pressure centrifugal fan 804 is started (to establish a stable negative pressure 3 seconds in advance), and the feeding motor 902 is started 3 seconds later. The sequential control equipment linkage is (to avoid the material entering the bulk material pipe 7 first but causing broken materials to be mixed in due to the lack of negative pressure).

[0084] Step S4: Match the frequency and interval of the feeding vibrator 10 and the dispersing vibrator 12 according to the material conveying rhythm to form a basic linkage control closed loop, ensuring that the material is dispersed and then separated and falls.

[0085] By adopting the above step S4, the feeding motor 902 is judged to have a medium-speed conveying rhythm of 1500 r / min (the material density in the bulk material pipe 7 is medium). The feeding vibrator 10 (fixed on the outer wall of the limiting hopper 6) is controlled to vibrate at a frequency of 30 Hz every 3 seconds (to shake off the material adhering to the inner wall of the limiting hopper 6 and avoid blockage). The dispersing vibrator 12 (fixed on the outer wall of the bulk material pipe 7) is controlled to vibrate continuously at a frequency of 40 Hz, driving the vibrating crossbar 13 (located in the bulk material pipe 7) to swing at a high frequency (to disperse the falling columnar material and separate the broken particles from the intact particles). The pressure fluctuation of the separation pipe is monitored by the first differential pressure sensor 8024. If it exceeds ±3 kPa (indicating that the material agglomeration leads to uneven adsorption), the frequency of the dispersing vibrator 12 is increased to 50 Hz (to enhance the dispersing effect). This forms a basic linkage closed loop of "vibration dispersion → negative pressure adsorption → pressure monitoring → vibration adjustment" (to ensure that the broken material can be effectively separated).

[0086] An embodiment of the present invention provides an intelligent integrated biomass fuel transfer and packaging device, wherein the controller 11 processes the following steps:

[0087] Step S5: Collect real-time pressure data of vacuum generating tube 801 through the second differential pressure sensor 8025 and vacuum pressure sensor 8027.

[0088] By employing the above step S5, the controller 11 receives the 25kPa pressure difference signal between the vacuum generating U-tube 801 and the outside environment collected by the second differential pressure sensor 8025 (the negative pressure inside the vacuum generating U-tube 801 is sufficient to drive the separation tube), and the -25kPa absolute pressure signal collected by the vacuum pressure sensor 8027 (the negative pressure inside the vacuum generating U-tube 801 is in the high-efficiency separation range) through the signal conditioning circuit. The controller converts the analog signal into a digital signal and stores it in real-time data in the format of "16:20:30.123--25kPa; 16:20:30.223--24kPa" at 100-millisecond intervals (real-time tracking of the negative pressure change inside the vacuum generating U-tube 801 to provide a basis for adjusting the separation force).

[0089] Step S6: Use the real-time pressure data from step S5 to generate the power regulation coefficient of the high-pressure centrifugal fan 804 using a PID algorithm.

[0090] By employing the above step S6, the controller 11 calls the PID algorithm to compare the real-time pressure of -25kPa in S5 with the preset optimal range (-20 to -30kPa). The calculated deviation is 0 (the target is the middle value of the range, -25kPa, at which point the adsorption force of the separator tube is stable), generating a power adjustment coefficient of 1.0 for the high-pressure centrifugal fan 804 (to maintain the current air volume); if the real-time pressure is -18kPa (deviation of 7kPa, insufficient negative pressure in the vacuum generating U-tube 801, and weak adsorption force of the separator tube), then an adjustment coefficient of 0.9 is generated (to reduce the fan power, reduce airflow impact, and avoid a sudden increase in negative pressure in the vacuum generating U-tube 801).

[0091] Step S7: Adjust the output of the high-pressure centrifugal fan 804 according to the power adjustment coefficient in step S6 to achieve negative pressure regulation in the vacuum generating U-tube 801.

[0092] By adopting the above step S7, the controller 11 sends the coefficient of 1.0 from S6 to the frequency converter of the high-pressure centrifugal fan 804 to maintain the power supply frequency of 50Hz to output the rated power, so that the negative pressure in the vacuum generating U tube 801 is stabilized at -20 to -30kPa (at this time, the first separation tube 802 and the second separation tube 803 can form an adsorption force of 15-25kPa through the negative pressure of the vacuum generating U tube 801, which is sufficient to suck up powdery and slightly damaged materials); if the coefficient is 0.9, the frequency is adjusted to 45Hz until the negative pressure enters the optimal range (to ensure that the adsorption force of the separation tube meets the standard).

[0093] Step S8: Receive pressure data from the first differential pressure sensor 8024 for the first separation tube 802 and the second separation tube 803, and combine the results of step S7 to drive the corresponding drive motor 8021 to operate.

[0094] By adopting the above step S8, the controller 11 receives the pressure data fed back by the first differential pressure sensor 8024, which shows that the pressure in the first separation tube 802 is 18 kPa (capable of adsorbing powdery materials) and the pressure in the second separation tube 803 is 14 kPa (insufficient adsorption force, difficult to remove moderately damaged materials). Combined with the optimal negative pressure of the vacuum generating U tube 801 in S7 (indicating that the vacuum generating U tube 801 has sufficient power), it is determined that the pressure in the second separation tube 803 is insufficient (<15 kPa) because the airflow in the corresponding slag separating tube is not smooth. The drive motor 8021 of the second slag separating tube 807 is driven to rotate forward (preparing to increase the opening degree of the valve plate 8022); if the pressure in the separation tube is ≥25 kPa (the adsorption force is too strong, and it may remove the whole material), the corresponding drive motor 8021 is controlled to rotate in reverse (reducing the opening degree of the valve plate 8022).

[0095] Step S9: The driving force is transmitted to the valve plate 8022 through the first bevel gear set 8023. The opening and closing degree of the valve plate 8022 in the first slag separation pipe 806, the second slag separation pipe 807 and the third slag separation pipe 808 are adjusted to complete the dynamic matching of negative pressure and slag separation airflow, and accurately separate powdery and broken materials.

[0096] By employing the above step S9, the drive motor 8021 drives the valve plate 8022 to rotate via the first bevel gear set 8023. The valve plate 8022 of the first slag distribution pipe 806 opens to 70 degrees (strongest airflow, bringing powdery materials from the vacuum generating U-tube 801 into the first slag distribution pipe 806), the valve plate 8022 of the second slag distribution pipe 807 opens to 45 degrees (medium airflow, bringing moderately damaged materials into the second slag distribution pipe 807), and the valve plate 8022 of the third slag distribution pipe 808 opens to 15 degrees (weaker airflow, bringing larger damaged materials into the third slag distribution pipe 808). Larger slag blocks fall into the slag block pipe 809 due to their own weight. The pressure is monitored by the third differential pressure sensor 8026. If the pressure of the first slag distribution pipe 806 fluctuates by +3 kPa (too much powdery material causing airflow obstruction), the valve plate 8022 is adjusted to 75 degrees (increasing airflow to avoid blockage), thus completing the dynamic matching of negative pressure and slag distribution airflow (achieving the recycling of damaged materials according to size).

[0097] An embodiment of the present invention provides an intelligent integrated biomass fuel transfer and packaging device, wherein the controller 11 processes the following steps:

[0098] Step S10: Integrate the speed of the feeding motor 902, the frequency of the dispersive vibrator 12, the pressure of the third differential pressure sensor 8026, and the weighing signal of the conveyor line to generate a real-time operating condition feature vector.

[0099] By adopting the above step S10, the controller 11 integrates the following: the feeding motor 902 has a speed of 1800 r / min (the material falls relatively quickly), the dispersing vibrator 12 has a frequency of 40 Hz (the material is moderately dispersed), the third differential pressure sensor 8026 has a pressure of 12 kPa (the material load in the slag separation pipe is moderate), and the conveyor line has a 30 kg weighing signal (the material bag is half full). The normalized processing is (1800÷3000=0.6), (40÷50=0.8), ((12-5)÷15≈0.47), (30÷50=0.6), and generates a real-time working condition feature vector [0.6,0.8,0.47,0.6] (reflecting the current state of "relatively fast feeding + good dispersion + moderate separation load + half full material bag").

[0100] Step S11: Based on the real-time working condition feature vector from step S10, identify the feeding speed trend, adjust the intensity of the dispersed vibrator 12, and synchronously send a coordination signal to the controller 11.

[0101] By adopting the above step S11, the controller 11 analyzes the vector of S10 and determines the "acceleration" trend (material falls faster and is more likely to aggregate) by the rotation speed trend of 1700→1750→1800→1820→1850r / min for 5 consecutive cycles (each cycle is 200 milliseconds) (the increase exceeds 5%). The frequency of the dispersing vibrator 12 is increased to 45Hz (to enhance the dispersing force of the vibrating crossbar 13 and prevent material from agglomerating) and a coordinated signal of "high-speed feeding + recommended negative pressure -25 to -30kPa" is sent to the controller 11 (requiring the separation tube to enhance the adsorption force to cope with more broken material).

[0102] Step S12: After receiving the coordination signal from step S11, the controller 11 adjusts the negative pressure adsorption force of the first separation tube 802 and the second separation tube 803 to achieve linkage adaptation of material dispersion and separation.

[0103] By adopting the above step S12, after receiving the coordination signal of S11, the controller 11 adjusts the power coefficient of the high-pressure centrifugal fan 804 from 1.0 to 1.1 (increasing the negative pressure inside the vacuum generating U tube 801), or opens the valve plate 8022 of the first slag separating pipe 806 from 70 degrees to 80 degrees (enhancing the slag separating airflow), so that the negative pressure of the first separation pipe 802 and the second separation pipe 803 increases from 20kPa to 25kPa (enhancing the adsorption force), and sucks away more powdery and broken materials generated during high-speed falling from the material distribution pipe 7 (avoiding the mixing of intact materials), thus realizing the linkage adaptation of material dispersion and separation.

[0104] Step S13: When the weighing signal reaches the preset threshold, the feeding motor 902 is stopped and the hydraulic rod 9011 drives the clamping plate 9012 to release in a coordinated action.

[0105] By adopting the above step S13, when the weighing signal of the conveyor line reaches the preset threshold of 50kg (the material bag is full), the controller 11 immediately stops the feeding motor 902 (the spiral blade 907 stops rotating, terminating the material conveying), and after a delay of 0.5 seconds (ensuring that the remaining material in the bulk material pipe 7 is dispersed by the vibrating cross bar 13 and adsorbed by the separation pipe, leaving only complete material falling into the bag), the controller controls the hydraulic rod 9011 to retract, driving the clamping plate 9012 away from the bag support plate 9010 (releasing the bag opening), thus obtaining a material bag filled with complete columnar material. The time is precisely controlled by the internal clock of the controller 11 (ensuring that the residual material is completely processed).

[0106] Step S14: During the execution of step S13, record each parameter, sensor data and action sequence, and generate a traceable log with timestamps to ensure the integrity of the bagged materials.

[0107] By adopting the above step S13, during the execution of S13, the controller 11 records data in the format of "timestamp + feeding + parameter + action", such as "16:25:10.321 + feeding + speed + 0 r / min + motor stop (feeding terminated); 16:25:10.321 + separation tube + negative pressure + 22 kPa (adsorption force at the last moment); 16:25:10.821 + hydraulic pressure + pressure + 5 MPa + clamping plate released (bag completed sealing; hydraulic pressure is the value of hydraulic rod 9011)", forming a traceable log with timestamp (recording key data such as the complete material bagging amount and the amount of broken material separated) and uploading it periodically, finally obtaining qualified biomass fuel bags and classified recycling of powdery and broken materials.

[0108] Example 1 provides a basic intelligent biomass fuel transfer and packaging integrated device. The core structure includes a packaging frame 1 and a fence 2 set on the packaging frame 1. A ladder 3 is fixed to the outside of the packaging frame 1, and a support frame 4 is fixed on the top. The support frame 4 supports the feeding hopper 5. The device also includes a limiting hopper 6, a dispersing pipe 7, a negative pressure separator 8, a feeding component 9, a feeding vibrator 10, a controller 11, a dispersing vibrator 12, a vibrating crossbar 13, and a mounting plate 14. The limiting hopper 6 is connected to the bottom of the feeding hopper 5, the dispersing pipe 7 is connected to the bottom of the limiting hopper 6, the negative pressure separator 8 is fixed on the dispersing pipe 7 and the mounting plate 14, the feeding component 9 is installed on the feeding hopper 5, the feeding vibrator 10 is symmetrically fixed on both sides of the feeding hopper 5, the controller 11 is fixed on the packaging frame 1, the dispersing vibrator 12 is installed on the dispersing pipe 7, the vibrating crossbar 13 is connected to the dispersing vibrator 12 and is located inside the dispersing pipe 7, and the mounting plate 14 is fixed on the packaging frame 1 as a support base for the negative pressure component.

[0109] The core components of the negative pressure separation unit 8 include a vacuum generating U-tube 801, a first separation tube 802, a second separation tube 803, a high-pressure centrifugal fan 804, an airflow pipe 805, a first slag separating pipe 806, a second slag separating pipe 807, a third slag separating pipe 808, and a slag block pipe 809. The vacuum generating U-tube 801 is fixed on the mounting plate 14. One end of the first separation tube 802 extends into the vacuum generating U-tube 801, and the other end is connected to the material distribution pipe 7. One end of the second separation tube 803 is connected to the first separation tube 802, and the other end is connected to the material distribution pipe 7. The high-pressure centrifugal fan 804 is fixed above the packing frame 1. One end of the airflow pipe 805 is connected to the output end of the high-pressure centrifugal fan 804, and the other end is connected to the vacuum generating U-tube 801. The first slag separating pipe 806, the second slag separating pipe 807, the third slag separating pipe 808, and the slag block pipe 809 are distributed sequentially, one above the other, at the end of the vacuum generating U-tube 801 away from the airflow pipe 805.

[0110] The unloading component 9 includes a motor base plate 901, an unloading motor 902, a transmission shaft 903, a second bevel gear set 904, a cone 905, a scraper 906, and a spiral blade 907. The motor base plate 901 is fixed on the unloading hopper 5. The base of the unloading motor 902 is mounted on the motor base plate 901. The transmission shaft 903 is rotatably mounted on the motor base plate 901. The input end of the second bevel gear set 904 is connected to the unloading motor 902, and the output end is connected to the top of the transmission shaft 903. The cone 905 is fixed on the transmission shaft 903. The scraper 906 is connected to the cone 905. The spiral blade 907 is fixed below the transmission shaft 903 and connected to the cone 905.

[0111] During operation, the controller 11 drives the feeding motor 902 to rotate, which in turn drives the transmission shaft 903, cone column 905, scraper plate 906, and spiral blade 907 to rotate via the second bevel gear set 904. The scraper plate 906 rotates along the inner wall of the limiting hopper 6 to prevent blockage, and the spiral blade 907 conveys the material quantitatively to the bulk material pipe 7 at a rhythm matching the conveying line speed (0.5~2m / s). At the same time, the high-pressure centrifugal fan 804 is started, and a negative pressure is formed in the vacuum generating U-tube 801 through the airflow pipe 805, which generates a pressure difference of 10-30kPa in the first separation pipe 802 and the second separation pipe 803, adsorbing the powdery and broken materials in the bulk material pipe 7. The materials are then discharged separately through the first slag separation pipe 806, the second slag separation pipe 807, the third slag separation pipe 808, and the slag block pipe 809. The intact materials fall into the material bag, realizing the basic separation and packaging functions.

[0112] Example 2 is a further optimization based on Example 1. The negative pressure separation component 8 is supplemented with a separation flange 8010, a hollow cover 8011, a limiting ring 8012, a filter plate 8013, a material limiting orifice plate 8014, a first intercepting net 8015, a first slag separating flange 8016, a second intercepting net 8017, a second slag separating flange 8018, a third intercepting net 8019, and a third slag separating flange 8020. The separation flange 8010 is fixed to the end of the first separation pipe 802 and the second separation pipe 803 furthest from the vacuum generating U-tube 801. The hollow cover 8011 is secured with bolts. The limiting ring 8012 is fixed inside the separating pipe and the separating flange 8010. The filter plate 8013 is sandwiched between the hollow cover 8011 and the limiting ring 8012. The limiting plate 8014 is fixed at the connection between the separating pipe and the dispersing pipe 7. The first intercepting net 8015, the second intercepting net 8017, and the third intercepting net 8019 are respectively fixed at the air inlets of the first slag separating pipe 806, the second slag separating pipe 807, and the third slag separating pipe 808. The corresponding first slag separating flange 8016, the second slag separating flange 8018, and the third slag separating flange 8020 are fixed at the air outlets of each slag separating pipe.

[0113] The unloading component 9 is equipped with a side support plate 908, an electric telescopic rod 909, a bag support plate 9010, a hydraulic rod 9011, and a clamping plate 9012. The side support plate 908 is fixed on the mounting plate 14. The non-telescopic end of the electric telescopic rod 909 is fixed on the side support plate 908. The bag support plate 9010 is connected to the telescopic end of the electric telescopic rod 909. The non-telescopic end of the hydraulic rod 9011 is fixed on the side support plate 908. The clamping plate 9012 is connected to the telescopic end of the hydraulic rod 9011.

[0114] The controller 11 synchronously acquires signals from the first differential pressure sensor 8024 (monitoring a 10-30 kPa pressure difference in the separation tube) and the second differential pressure sensor 8025 (monitoring a 15-40 kPa pressure difference in the vacuum generating U-tube 801) at a frequency of 50 times per second via its built-in interface, as well as the conveyor line status (0.5-2 m / s during operation, 0 m / s when stopped), forming a multi-source signal acquisition matrix of "timestamp + sensor type + signal value". Based on this matrix, the controller 11 extracts effective parameters (such as a negative pressure of 20 kPa in the separation tube, etc.). The conveyor line operation identifier "1" is normalized (e.g., (20-10) ÷ (30-10) = 0.5) to generate standardized control commands (e.g., starting the feeding motor 902 + 1500 r / min), and controlling the equipment start and stop according to the preset settings—first starting the high-pressure centrifugal fan 804 (power supply frequency 50Hz), and then starting the feeding motor 902 3 seconds later. At the same time, the parameters of the feeding vibrator 10 (30Hz frequency, 3-second interval vibration) and the dispersed vibrator 12 (40Hz continuous vibration) are matched to form a basic linkage closed loop.

[0115] During operation, the filter plate 8013 intercepts large particulate impurities, the material limiting orifice plate 8014 controls the adsorption flow rate, and each interception net further filters materials of different sizes; the bag support plate 9010 is adapted to different material bags through the electric telescopic rod 909, and the clamping plate 9012 fixes the bag mouth through the hydraulic rod 9011, which greatly improves the separation accuracy and operational adaptability.

[0116] Example 3, based on Example 2, achieves an intelligent upgrade. The negative pressure separator 8 is supplemented with a drive motor 8021, a valve plate 8022, a first bevel gear set 8023, a first differential pressure sensor 8024, a second differential pressure sensor 8025, a third differential pressure sensor 8026, and a vacuum pressure sensor 8027. The drive motor 8021 is fixed on each slag distribution pipe, the valve plate 8022 is rotatably installed inside the slag distribution pipe, the input end of the first bevel gear set 8023 is connected to the shaft of the drive motor 8021, and the output end is connected to the valve shaft of the valve plate 8022; the first differential pressure sensor 8024 monitors the pressure of the separation pipe, the second differential pressure sensor 8025 monitors the pressure of the vacuum generating U-tube 801, the third differential pressure sensor 8026 monitors the 5-20 kPa pressure difference in the slag distribution pipe, and the vacuum pressure sensor 8027 monitors the -50 to -10 kPa absolute pressure inside the vacuum generating U-tube 801.

[0117] The controller 11 acquires the real-time pressure of the vacuum generating U-tube 801 at 100-millisecond intervals, calls the PID algorithm to compare it with the optimal separation negative pressure range (-20 to -30 kPa), generates the power adjustment coefficient of the high-pressure centrifugal fan 804 (e.g., coefficient 1.0 when the pressure is -25 kPa, coefficient 0.9 when the pressure is -18 kPa), and adjusts the output of the high-pressure centrifugal fan 804 through the frequency converter controller (coefficient 1.0 corresponds to 50 Hz, 0.9 corresponds to 45 Hz); at the same time, it combines the first separation tube 802 (18 kPa) and the second The pressure feedback from the separator 803 (14kPa) drives the corresponding drive motor 8021 to operate, which in turn drives the valve plate 8022 to adjust the opening degree through the first bevel gear set 8023. The opening degree of the first slag separating pipe 806 is 70 degrees for light powdery materials, 45 degrees for the second slag separating pipe 807 for moderately damaged materials, and 15 degrees for the third slag separating pipe 808 for more damaged materials. If the pressure fluctuation of the slag separating pipe exceeds ±2kPa, the opening degree is finely adjusted (e.g., from 70 degrees to 75 degrees) to achieve dynamic matching between negative pressure and slag separating airflow.

[0118] The system integrates the rotational speed of the feeding motor 902 (1800 r / min, normalized 0.6), the frequency of the dispersive vibrator 12 (40 Hz, normalized 0.8), the pressure from the third differential pressure sensor (12 kPa, normalized 0.47), and the weighing value of the conveyor line (30 kg, normalized 0.6) to form a real-time operating condition feature vector [0.6, 0.8, 0.47, 0.6]. Through trend analysis (where the feeding speed increases by more than 5% for five consecutive cycles), an "acceleration" trend is determined. The frequency of the dispersive vibrator 12 is then increased to 45 Hz, and a coordinated signal of "high-speed feeding + recommended negative pressure -25 to -30 kPa" is sent to the controller 11. Upon response, the controller 11 increases the fan speed. Adjust the power (coefficient 1.0 to 1.1) or increase the opening degree of valve plate 8022 (70 degrees to 80 degrees) to increase the negative pressure of the separation tube from 20 kPa to 25 kPa; when the weighing reaches the 50 kg threshold, the feeding motor 902 is triggered to stop, and after a delay of 0.5 seconds, the hydraulic rod 9011 is driven to retract, causing the clamping plate 9012 to release, and the log is recorded in the format of "timestamp + feeding + parameter + action" (such as "16:25:10.321 + feeding + speed + 0 r / min + motor stop") to achieve full process traceability; during operation, through precise negative pressure adjustment and parameter matching, the integrity of the bagged material is ensured, which greatly improves the intelligence level of the device and the stability of product quality.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
