Description

Technical Field

[0001] This utility model relates to the technical field of wood chip processing equipment, and in particular to a wood chip feeding, storage and conveying device. Background Technology

[0002] Wood chips are fine wood particles or fibrous waste produced during wood processing. They mainly originate from the logging, sawing, planing, and crushing stages of timber. Wood chips are a widely distributed and high-volume renewable resource. Wood chip feeding, storage, and conveying devices are specialized equipment for processing wood chips, ensuring efficient processing and utilization of wood chips and promoting the transformation of wood chips from industrial waste into high-value resources.

[0003] Traditional sawdust feeding, storage, and conveying devices consist of a vertical cylindrical silo, a conveying device, a feed pipe, and a blower. The sawdust is stored in the vertical cylindrical silo and then conveyed into the feed pipe via the conveying device. In the pipeline conveying process, the airflow generated by the blower propels the sawdust to flow within the feed pipe. However, during use, sawdust accumulates at the bottom of the vertical cylindrical silo, causing blockages, and the top cover eventually fails to prevent rainwater from entering, causing the sawdust to become damp and unusable.

[0004] Existing technologies improve the silo section by using a sealed silo for storage, with a conical or inclined bottom design to prevent sawdust from accumulating and causing blockages, thus reducing maintenance costs. However, in actual use, the blower cannot flexibly switch between negative and positive pressure airflow modes, making the blower inflexible and unable to work in different production scenarios. Furthermore, over time, sawdust residue can cause pipe blockages, requiring cleaning and increasing maintenance costs. Utility Model Content

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 and Figure 4This utility model provides an embodiment of a sawdust feeding, storage, and conveying device, including a hopper 1 as the core storage component for temporarily storing sawdust to be processed, providing raw material reserves for the entire system. A conveying assembly 8 is installed at the bottom of the hopper 1, mainly for conveying the sawdust in the hopper 1 to subsequent processing stages. A lifting assembly 6 is installed at the rear of the hopper 1 for adjusting the height of the hopper 1 to adapt to different working conditions and improve the system's flexibility. A blower 3 is installed on the left side of the hopper 1 to provide wind power, pushing the sawdust through airflow. The flow of wood chips is improved to reduce wood chip retention. The output end of the blower 3 is equipped with a conveying pipe 2, which is responsible for conveying wood chips to the blower 3. The right end of the conveying pipe 2 is equipped with an anti-blocking mechanism 4 to prevent wood chips from clogging during the conveying process. The outer wall of the blower 3 is equipped with a connecting mechanism 5, which is used to quickly connect or disconnect the conveying pipe 2 to switch between negative pressure and positive pressure airflow modes. The left side of the hopper 1 is equipped with a separation component 7 to separate and screen the processed materials, separating qualified wood chips from impurities or unqualified wood chips, ensuring that the purity and specifications of the output wood chips meet the standards.

[0036] The anti-blocking mechanism 4 includes a conveying pipe 401. Wood chips pass through the main channel of the anti-blocking mechanism 4. The left end of the conveying pipe 401 is connected to the right end of the conveying pipe 2. A screening inclined plate 402 is provided inside the left end of the conveying pipe 401 to perform preliminary screening of the incoming wood chips and intercept oversized pieces. A conical groove 403 is provided on the left side of the screening inclined plate 402 to receive the wood chips after screening. The conical structure gathers the material and reduces dispersion resistance. A rotating shaft 404 is rotatably connected to the left side of the inner wall of the conical groove 403. Multiple rotating blades 405 are fixedly connected to the right end of the outer wall of the rotating shaft 404. The rotating shaft 404 acts as a power transmission component to drive the rotating blades 405 to rotate, making them rotate at high speed in a crushing cone. The sawdust conveyed by the trough 403 is prevented from clogging the pipe and ensures that the particle size of the material meets the conveying requirements. A motor 406 is fixedly connected to the left end of the rotating shaft 404 to provide power to the rotating shaft 404 and the rotating blades 405. A screening plate 407 is set at the bottom of the multiple rotating blades 405 to perform secondary screening on the crushed sawdust, ensuring that only sawdust that meets the particle size requirements passes through. A separation plate 408 is fixedly connected to the left end of the inner wall of the conveying pipe 401, which can change the flow direction of the sawdust or form a buffer to prevent the high-speed flowing sawdust from directly impacting the inner wall of the conveying pipe 2. An arc-shaped guide plate 409 is fixedly connected to the left end of the inner wall of the conveying pipe 401 to guide the processed sawdust smoothly into the next stage along the arc-shaped path.

[0037] Specifically, the wood chips in hopper 1 enter conveying pipe 401 through conveying assembly 8. They first undergo preliminary screening by screening inclined plate 402, which intercepts wood blocks or impurities that are too large in diameter. These intercepted materials slide along the inclined plate to the conical groove 403 on the side. The conical structure gathers the dispersed wood chips into bundles and flows towards the rotating processing area. At this time, motor 406 drives rotating shaft 404 to drive rotating blade 405, which can break up the clumps of wood chips to ensure that they meet the conveying requirements. The broken wood chips undergo secondary screening through screening plate 407 to further control the particle size of the material. Qualified wood chips fall after passing through the screen holes. Then, under the obstruction of separation plate 408, the flow direction is changed to avoid high-speed airflow directly impacting the inner wall of the pipe and causing wear. Subsequently, under the guidance of arc-shaped guide plate 409, they enter conveying pipe 2 along a smooth arc path and then enter the blower 3.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The connecting mechanism 5 includes two connecting ports 501. The outer walls of the two connecting ports 501 are respectively fixedly connected to the right side and top of the outer wall of the blower 3. The connecting ports 501 serve as transitional connectors between the blower 3 and the conveying pipe 2, directly connecting to the blower 3 to form a channel. A flange 502 is fixedly connected to the left end of the outer wall of the conveying pipe 2, fixed to the end of the conveying pipe 2. By fitting against the flange face of the connecting port 501, the connection between the conveying pipe 2 and the blower 3 is transformed into a rigid connection between flanges, enhancing overall stability. The flange 502 and the outer walls of the two connecting ports 501 are all provided with... There are multiple threaded grooves 503, and the inner walls of the multiple threaded grooves 503 are threaded with bolts 504. The threaded grooves 503 provide a threaded mating base for the bolts 504, ensuring that the bolts 504 can be screwed in stably and generate axial preload, which tightly presses the flange 502 and the connection port 501 together to achieve mechanical fixation. A rubber sealing ring 505 is provided on the adjacent side of the right connection port 501 and the flange 502. The rubber sealing ring 505 fills the gap between the flange 502 and the connection port 501 by utilizing the elastic deformation characteristics of rubber. The rubber sealing ring 505 is threadedly connected to the corresponding multiple bolts 504.

[0039] Specifically, the core component of the connecting mechanism 5 is the connecting port 501. One connecting port 501 has its outer wall fixed to the output port on the right side of the blower 3, and the other connecting port 501 is fixed to the top of the outer wall of the blower 3. The right connecting port 501 serves as a transitional connector between the blower 3 and the conveying pipe 2. The left end of the outer wall of the conveying pipe 2 is fixedly connected to a flange 502 that matches the connecting port 501. By precisely fitting the flange face of the connecting port 501, the conveying pipe 2 is rigidly connected to the blower 3, ensuring the stability of the overall structure during operation and reducing loosening of the connection due to vibration and other factors. The flange 502 and the outer walls of the two connecting ports 501 are provided with multiple threads. The outer threads of multiple bolts 504 in the groove 503 match the inner threads of the groove 503. The groove 503 provides a stable threaded fit base for the bolts 504, ensuring that the bolts 504 can generate sufficient axial preload to tightly press the flange 502 and the connection port 501 together. A rubber sealing ring 505 is also provided between the flange 502 and the connection port 501 on the right side. Utilizing the good elastic deformation characteristics of rubber itself, when the flange 502 and the connection port 501 are pressed by the bolts 504, corresponding deformation occurs, thereby fully filling the gap between the flange 502 and the connection port 501, effectively preventing material leakage or airflow loss.

[0040] Reference Figure 5 , Figure 6 and Figure 7The lifting assembly 6 includes two fixed rods 601. The adjacent sides of the two fixed rods 601 are fixedly connected to the left and right sides of the hopper 1, respectively, serving as the support frame of the lifting assembly 6. This connects the hopper 1 to the lifting assembly 6, ensuring the stability of the hopper 1 during lifting and preventing tilting or shaking. A connecting plate 602 is fixedly connected to the rear side of each of the two fixed rods 601. Two sliders 603 are fixedly connected to the left and right sides of the rear end of the connecting plate 602. T-shaped guide rails 604 are slidably connected to the inner walls of the two sliders 603. The T-shaped guide rails 604 provide a guide track for the sliders 603. Through sliding cooperation with the sliders 603, the lifting movement of the hopper 1 is constrained to a fixed path. A lifting machine 605, the power source of the lifting assembly 6, is fixedly connected to the rear side of the connecting plate 602, driving the connecting plate 602 and the hopper 1 to move up and down, thereby achieving height adjustment. The separation component 7 includes a second conveying pipe 702. The right end of the second conveying pipe 702 is connected to the top left end of the hopper 1, connecting to the channel of the hopper 1 to convey the separated wood chips into the hopper 1. The left end of the second conveying pipe 702 is connected to a separator 701, the core equipment of the separation component 7, which processes the incoming wood chips to ensure the purity or specifications of the wood chips. The rear right end of the separator 701 is connected to a recovery pipe 703, which is used to remove the impurities separated by the separator 701. The rear end of the recovery pipe 703 is connected to a recovery box 704 to collect the separated material conveyed by the recovery pipe 703 for subsequent centralized processing. The conveying assembly 8 includes a connecting pipe 802, the top of which is connected to the bottom of the hopper 1, connecting the channel of the hopper 1 so that the material in the hopper 1 can smoothly enter the conveying assembly 8. The bottom end of the connecting pipe 802 is connected to the outer shell 801, which serves as a protective shell for the conveying assembly 8 and prevents sawdust from spilling during the conveying process. The left end of the outer shell 801 is fixedly connected to the right end of the conveying pipe 401. The inner wall of the outer shell 801 is equipped with a tubular chain conveyor 803, which is the core power component of the conveying assembly 8, and evenly conveys the sawdust along the pipe direction to the next stage.

[0041] Specifically, the fixed rod 601 is fixedly connected to the hopper 1 to ensure the stability of the hopper 1 during lifting and preventing tilting or shaking. First, the lifting machine 605 is started, which drives the connecting plate 602 to move up and down. Then, the slider 603 slides in the inner wall of the T-shaped guide rail 604 to limit the movement trajectory, ensuring smooth vertical movement during lifting and avoiding deviation. At the same time, the T-shaped guide rail 604 will bear the lateral force of the hopper 1, enhancing the stability of the overall structure. The wood chips are separated and screened by the separator 701 to ensure the purity or specifications of the output wood chips. The wood chips that pass through will enter the hopper 1 through the conveying pipe 702, while the wood chips that do not pass through will enter the recycling box 704 through the recycling pipe 703 for recycling and reprocessing, avoiding direct discharge that would cause waste or pollution. The sawdust in the hopper 1 enters the outer casing 801 through the bottom connecting pipe 802, and then goes to the tubular chain conveyor 803. The tubular chain conveyor 803 then moves inside the outer casing 801, conveying the sawdust along the pipe direction to the next stage. At this time, the outer casing 801 will prevent the sawdust from spilling during the conveying process.

[0042] Reference Figure 1 and Figure 2 A sensor 9 is fixedly connected to the front side of the outer wall of the silo 1. The sensor 9 is electrically connected to the blower 3 to monitor the material status in the silo 1 in real time and control the blower 3 in conjunction to achieve intelligent operation. A conveying pipe 3 10 is connected to the left side of the separator 701. A bag filter 11 is connected to the left side of the conveying pipe 3 10. The bag filter 11 is responsible for purifying dust-containing gas, achieving environmentally friendly emissions and recovering fine materials. The conveying pipe 3 10 serves as a channel connecting the separator 701 and the bag filter 11. An electromagnetic vibrator 12 is threadedly connected to the front side of the outer wall of the conveying pipe 401. The right end of the electromagnetic vibrator 12 is threadedly connected to the front side of the outer wall of the outer shell 801. High-frequency vibration prevents sawdust from clogging the conveying pipe 401 and the outer shell 801 and assists in material flow. The inner wall of the conveying pipe 401 is provided with an anti-stick coating to reduce the friction and adsorption between sawdust and the inner wall of the conveying pipe 401 and improve the smoothness of conveying.

[0043] Specifically, sensor 9 is installed on the front side of the outer wall of hopper 1 to accurately monitor the height and falling speed of wood chips. The system automatically adjusts the power of blower 3 or the conveying speed. When the material level is low, the power of blower 3 is increased to speed up the feeding speed; when the material level is high, the conveying speed is reduced to prevent wood chips from overflowing, achieving energy-saving operation. A bag filter 11 is installed to purify the wood chip dust, preventing it from being emitted into the air and reducing the harm to the human body from dust inhalation. The purified wood chips are then conveyed to separator 701 through conveyor pipe 3 10 for further separation and screening. Electromagnetic vibrator 12 causes micro-vibrations in conveyor pipe 1 401 through high-frequency vibration, thereby breaking up clumps of wood chips and shaking off adsorbed fibers, ensuring continuous flow of wood chips and avoiding conveying interruptions due to blockages. The anti-stick coating on the inner wall of conveyor pipe 1 401 reduces the friction between wood chip fibers and the pipe wall, and together with electromagnetic vibrator 12, forms a double protection, improving conveying efficiency.

[0044] Working principle: First, the sawdust is placed into the bag filter 11 to separate the light impurities and dust. Then, it is conveyed through the conveyor pipe 3 10 into the separator 701 for further separation and screening. The unqualified sawdust enters the collection box 704 through the recovery pipe 703, while the qualified sawdust enters the hopper 1 through the conveyor pipe 2 702. After that, the sawdust is conveyed by the connecting pipe 802 to the tubular chain conveyor 803. The tubular chain conveyor 803 then conveys the sawdust to the first conveyor pipe 401, and then the sawdust is screened again on the screening inclined plate 402. The qualified sawdust sinks into the conveying pipe 2, while the unqualified sawdust enters the conical trough 40. After step 3, motor 406 drives rotating shaft 404 to rotate, which in turn drives rotating blade 405 to crush wood chips. The wood chips are then screened by screening plate 407. Those that pass through sink into conveying pipe 2, while those that do not pass through continue to be crushed by rotating blade 405. The wood chips then change their flow direction under the obstruction of separation plate 408, and are then guided by arc-shaped guide plate 409 to enter conveying pipe 2 along a smooth arc path. The wood chips in conveying pipe 2 are then moved by blower 3. The wood chips adhering to the inner wall of conveying pipe 401 will fall off due to the vibration of electromagnetic vibrator 12, thereby preventing the conveying pipe 401 from being blocked.

[0045] When switching between negative and positive pressure airflow modes, the flange 502 on the feed pipe 2 must first be separated from the connection port 501 of the blower 3. Switching is achieved by connecting the top connection port 501 and the right connection port 501 of the blower 3. During disassembly, all rubber sealing rings 505 must first be loosened and removed from the threaded grooves 503 of the flange 502 and connection port 501, releasing the constraint between the flange 502 and connection port 501. As the bolts 504 are unscrewed, the compressed rubber sealing rings 505 will gradually return to their original shape. Once the rubber sealing rings 505 are completely removed, the disassembly of the feed pipe 2 is complete. Then, during the connection process, first connect the flange 502 to the connection port 501. Initial positioning is achieved through planar bonding of part 2. At this time, the rubber sealing ring 505 is clamped between the flange 502 and the connection port 501. Then, the bolt 504 is passed through the threaded groove 503 of the flange 502 and the connection port 501. By tightening, an axial preload is generated, which tightly presses the flange 502 and the connection port 501 together. At this time, the rubber sealing ring 505 undergoes elastic deformation under the preload of the bolt 504. Its surface is tightly bonded to the flange 502 and the connection port 501 to fill the gap and prevent wood chips from leaking out of the gap. Then, the material conveying pipe 2 and the blower 3 are connected. At this time, the flange 502 is tightly bonded to the end face of the conveying pipe 401, generating sufficient friction to resist the vibration of the equipment during operation and prevent the threaded connection from loosening.
