Description

Technical Field

[0001] This invention relates to the field of biomass fiber processing technology, specifically to a conveyor-type continuous biomass fiber processing device. Background Technology

[0002] Biomass fiber, as a renewable and environmentally friendly material, has broad application prospects in various fields such as textiles, building materials, and biodegradable products. The efficiency and quality of its processing directly affect the performance and production cost of the final product. Currently, the processing flow of biomass fiber typically includes multiple stages such as washing, conveying, drying, crushing, screening, and feeding. However, existing processing methods generally suffer from the following problems: Traditional biomass fiber processing often employs segmented operations, with each processing step relying on independent equipment. This necessitates manual transfer of materials between different machines, resulting in long processing cycles, high labor intensity, and significant material loss and secondary pollution, making it difficult to meet the demands of large-scale continuous production. In the cleaning stage, existing equipment often uses immersion or uneven spraying methods, making it difficult to thoroughly remove impurities from the material surface. Furthermore, the wastewater discharge after cleaning is inefficient, affecting subsequent processing. Simultaneously, the high moisture content of the cleaned material, if not dried promptly or evenly, can easily lead to clumping, causing blockages in subsequent conveying and crushing processes.

[0003] In terms of the coordinated processing of conveying and drying, existing equipment lacks an effective linkage design. During the drying process, materials tend to accumulate in the conveying channel, which not only reduces drying efficiency but may also cause equipment failure due to blockage. Although some devices are equipped with anti-blocking structures, they are mostly passive cleaning methods and cannot achieve real-time anti-blocking and simultaneous improvement of drying effect. In the crushing stage, the crushing rollers of existing equipment are mostly driven by a single drive or have insufficient meshing precision, resulting in uneven crushing of materials. Furthermore, the connection between screening and crushing stages is not tight, and substandard materials cannot be returned for timely processing, affecting the stability of product quality.

[0004] Quantitative control during the feeding process is one of the key steps in biomass fiber processing. Existing quantitative feeding devices mostly use valve throttling or screw conveyor methods, which suffer from low feeding accuracy and material adhesion at the discharge port, leading to poor feeding flow. This makes it difficult to achieve uniform and accurate quantitative discharge, thus affecting the continuity of subsequent packaging or reprocessing processes. In addition, the existing processing devices have dispersed units, resulting in a complex overall structure, large footprint, and a lack of centralized collaborative control mechanisms. The operating parameters of each device are difficult to match precisely, leading to low processing efficiency and high energy consumption.

[0005] In summary, current biomass fiber processing equipment suffers from drawbacks such as low continuity, poor coordination between stages, susceptibility to clogging, inadequate drying and pulverizing effects, and insufficient quantitative feeding accuracy, which hinder the large-scale and efficient development of the biomass fiber industry. Therefore, developing an integrated, continuous, and highly automated biomass fiber processing device that effectively addresses the technical challenges in cleaning, drying, clogging prevention, pulverizing, and quantitative feeding is of significant practical importance and application value.

[0006] Based on this, this solution proposes a conveyor-type continuous processing device for biomass fibers. Summary of the Invention

[0007] The purpose of this invention is to provide a conveying-type continuous processing device for biomass fibers to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a conveying type continuous processing device for biomass fibers, comprising a support foundation and sequentially linked cleaning unit, conveying and pushing unit, drying and anti-clogging unit, crushing and screening unit, and quantitative feeding unit. Each unit is integrated and installed on the support foundation to realize continuous automated processing of biomass fibers from cleaning to quantitative discharge.

[0010] Using the above technical solution, the base and supporting steel structure form a stable installation foundation. Through mechanical optimization design, the weight of each unit can be effectively distributed to ensure stable operation of the device. Each component is precisely assembled with bolts to ensure coaxiality and perpendicularity, providing structural support for linkage operation. The control panel integrates a PLC controller and a touch screen display, which can receive operating signals in real time and output precise control commands to achieve stepless adjustment of each parameter and ensure matching of the operating status of each unit.

[0011] Preferably, the cleaning unit includes a water tank, a water pump, a fixed pipe, nozzles, and a first conveyor belt. The first fixed frame and the second fixed frame are fixed to the top of the mounting plate. The first conveyor belt is rotatably mounted between the two fixed frames and has a water leakage hole.

[0012] Using the above technical solution, the feeding funnel has a funnel-shaped structure with a polished inner wall to prevent material adhesion and retention. The first conveyor belt is made of corrosion-resistant, high-strength material, and the surface drainage holes can quickly discharge sewage to prevent small materials from falling. The running speed is adjustable, and the fixed pipe maintains a reasonable distance from the conveyor belt. The nozzle adopts a high-pressure atomization design to achieve all-round, dead-angle-free rinsing. The water tank is made of stainless steel, and the water filling pipe is equipped with a flow control valve. The internal liquid level sensor can monitor the water level in real time. The water pump is a self-priming centrifugal pump with stable flow and high head to ensure cleaning effect.

[0013] Preferably, the conveying and pushing unit includes a lower slide plate, a pushing tube, a spiral pushing rod, and a first motor.

The feeding tube is located at the discharge end of the pushing tube and is connected to it.

[0014] The above technical solution features a tilted sliding plate with an anti-slip surface, ensuring smooth material flow into the push tube. The push tube is a cylindrical steel pipe with a smooth inner wall and a flared opening at the feed end. The spiral push rod blades adopt a gradually increasing spiral angle design to facilitate the reception and uniform pushing of materials, preventing compression and clumping. The material is high-strength alloy steel. The first motor is a variable frequency geared motor, driven by a coupling, allowing for precise speed adjustment. The connection between the feed tube and the push tube has a rounded transition to reduce material retention.

[0015] Preferably, the drying anti-clogging unit includes a fan, an air inlet pipe, a feeding pipe, a second motor, a rotating shaft, striking cams, a striking plate, a return spring, and striking rods. Two air inlet pipes with check valves are fixed to the top of the feeding pipe, and a fan is installed at the top of both. The fan has a heating wire inside, and a drain hole is opened at the bottom of the feeding pipe. The second motor and a fixing rod are fixed on the supporting steel frame. The rotating shaft is fixedly sleeved on the output shaft of the second motor, and two striking cams are fixed on it. Three striking rods are slidably installed on the fixing rod, and the same striking plate is fixed at the bottom. The striking rods are sleeved with a return spring, and the striking cams are adapted to the striking plate.

[0016] Using the above technical solution, the blower is a centrifugal hot air blower, the heating wire is made of nickel-chromium alloy, which has high heating efficiency and adjustable heating temperature. The air inlet pipes are symmetrically distributed, the check valve can prevent material or hot air backflow, the inner wall of the feed pipe is coated with Teflon to reduce material adhesion, the bottom drain hole can drain condensed water in time, the second motor is a stepper motor, the speed is precisely controllable, when the striking cam rotates, it drives the striking plate and striking rod to reciprocate, the reset spring ensures smooth reset, and achieves real-time anti-clogging and improved drying uniformity.

[0017] Preferably, the crushing and screening unit includes a crushing box, a receiving funnel, crushing rollers, a third motor, a linkage gear, and a screening screen. The receiving funnel is fixed to the top of the crushing box and connects the feeding pipe to the feeding end of the crushing box. Two crushing rollers are rotatably installed inside the crushing box, and a linkage gear is fixed to one end of each roller and they mesh with each other. The third motor is fixed to the crushing box, and its output shaft is fixed to the corresponding crushing roller. The screening screen is located below the crushing rollers.

[0018] Using the above technical solution, the receiving funnel can ensure that the material enters the crushing box smoothly. The two crushing rollers are driven by the meshing of the linkage gears and rotate in opposite directions, which can fully squeeze and shear the material. The crushing roller surface is equipped with wear-resistant tooth patterns to improve the crushing effect. The third motor is a geared motor to provide sufficient torque. The screen is a detachable structure and the aperture can be selected according to the needs. Unqualified materials can be returned for re-crushing.

[0019] Preferably, the quantitative feeding unit includes a feeding pipe, a fixed box, a fourth motor, a rotating disk, a double-section connecting rod, a movable block, a sealing plate, and a fixed block. The feeding pipe is connected to the discharge end of the crushing box, and fixed boxes are fixed on both sides. A fourth motor is installed at the bottom of each fixed box. A movable hole is opened at the junction of the fixed box and the feeding pipe, and a sealing plate is slidably installed inside. The sealing plate is fixed to the fixed block, and a movable block is slidably installed on it. The rotating disk is connected to the output end of the fourth motor and is hinged to the movable block through the double-section connecting rod. A second conveyor belt is provided below the quantitative feeding unit, which is installed on the base and evenly distributed with partition plates.

[0020] Using the above technical solution, the fourth motor is a stepper motor that drives the rotating disk to rotate. Through the double-section connecting rod, the movable block and the sealing plate slide back and forth to realize the opening and closing of the feeding pipe and control the feeding amount. The surface of the sealing plate is coated with a wear-resistant coating to reduce material adhesion. The fixed box provides guidance and protection for the sealing plate. The partition plate on the second conveyor belt forms an independent feeding area to further ensure quantitative accuracy and adapt to subsequent packaging or reprocessing processes.

[0021] Compared with the prior art, the beneficial effects of the present invention are: I. Continuous integrated design significantly improves processing efficiency: This invention integrates cleaning, conveying, drying and anti-clogging, crushing and screening, and quantitative feeding units into the same support base. Each unit operates in sequence without the need for manual material handling, completely solving the problems of high labor intensity and long processing cycles in traditional segmented operations. Through the control panel, the motors, fans, and water pumps are coordinated and controlled. The entire process from material feeding to quantitative discharge is automated and continuous, which reduces material loss and secondary pollution, meets the needs of large-scale production, and significantly improves overall processing efficiency.

[0022] II. Optimized Drying and Anti-clogging Synergy to Ensure Smooth Processing and Material Quality: An innovative design combining hot air drying and active anti-clogging is adopted. Hot air generated by the fan is evenly introduced into the discharge pipe through the air inlet duct, working in conjunction with the drainage holes at the bottom of the discharge pipe to achieve rapid and uniform drying of the material, preventing clumping. Simultaneously, a second motor drives a striking cam to reciprocate and strike the discharge pipe, preventing material blockage in real time. The material also shakes under the striking action, further improving drying uniformity. Compared to traditional passive anti-clogging devices that are disconnected from drying, this design effectively reduces the risk of equipment failure, ensures a continuous and smooth processing flow, and improves the quality of material drying.

[0023] III. Precise and controllable crushing and quantitative control enhance product stability and subsequent adaptability: The crushing process uses a double crushing roller meshing drive to ensure uniform material crushing, and the screening screen filters out qualified materials in real time to ensure consistent product particle size; the quantitative feeding unit adopts a dual-motor driven double-section linkage mechanism, which drives the sealing plate to reciprocate to open and close the feeding pipe, and works with the second conveyor belt with a partition plate to achieve precise and uniform quantitative discharge; this design solves the problems of uneven crushing, low quantitative accuracy, and poor feeding in traditional methods, which not only improves the quality stability of biomass fiber products, but also accurately adapts to subsequent packaging or reprocessing processes, reducing subsequent production errors.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6 The present invention provides a technical solution: a conveying type continuous processing device for biomass fibers, including a supporting foundation and a washing unit, a conveying and pushing unit, a drying and anti-clogging unit, a crushing and screening unit and a quantitative feeding unit connected in sequence. Each unit is integrated and installed on the supporting foundation to realize continuous automated processing of biomass fibers from washing to quantitative discharge.

[0028] When implementing this embodiment, it is necessary to first check the tightness of the connection parts of each unit, especially the meshing gap between the crushing roller 23 and the linkage gear 29, and the coaxiality between the spiral push rod 13 and the push tube 14, to ensure that there is no looseness or jamming. At the same time, verify the stability of the circuit connection between the control panel 2 and each motor, fan 5, and water pump 38 to avoid power outages or signal interruptions during operation.

[0029] Combination Figure 1-6 As shown, in this embodiment, the nozzle 34 of the cleaning unit adopts a detachable design, the water tank 37 has a built-in liquid level sensor, the spiral push rod 13 blade of the conveying and pushing unit has a gradually changing spiral angle structure, the impact cam 20 of the drying and anti-clogging unit and the impacted plate 18 have an adaptive curved surface design, the screen 25 of the crushing and screening unit can be replaced as needed, and the sealing plate 40 of the quantitative feeding unit has a wear-resistant coating on its surface.

[0030] In this embodiment, before starting the equipment, clean water is injected into the water tank 37 through the water inlet pipe 36. The water level threshold of the water tank 37 is set according to the characteristics of the raw materials. At the same time, the screen 25 with the corresponding aperture is selected according to the required particle size, and the speed parameters of the fourth motor 28 are adjusted. The opening and closing frequency and stroke of the sealing plate 40 are preset to ensure the accuracy of quantitative feeding.

[0031] Combination Figure 1-6 As shown, in this embodiment, the heating wire inside the fan 5 is made of nickel-chromium alloy, the air inlet pipe 12 is equipped with a check valve, the inner wall of the discharge pipe 11 is coated with Teflon and has a drain hole at the bottom, when the second motor 16 drives the striking cam 20 to rotate, the striking rod 22 realizes the reciprocating striking action under the action of the return spring 21, and the double crushing rollers 23 realize the reverse synchronous rotation through the linkage gear 29.

[0032] In this embodiment, during the processing, the running speed of the first conveyor belt 30 and the water supply flow of the water pump 38 are monitored in real time to ensure that the atomization range of the nozzle 34 completely covers the surface of the conveyor belt during raw material cleaning. If the material flow speed in the feed pipe 11 is detected to slow down, the speed of the second motor 16 can be increased through the control panel 2 to enhance the anti-blocking effect. At the same time, the wind speed of the fan 5 is appropriately increased to accelerate the drying and conveying of materials.

[0033] Combination Figure 1-6 As shown, in this embodiment, the partition plates 4 evenly arranged on the second conveyor belt 3 form an independent feeding area, and their spacing matches the opening and closing cycle of the sealing plate 40. The fixed box 26 provides sliding guidance for the sealing plate 40, and the double-section connecting rod 41 realizes the power transmission between the rotating disk 42 and the movable block 39 through the hinge structure.

[0034] In this embodiment, when the amount of substandard material accumulated on the screening screen 25 reaches a certain level, the equipment operation can be paused, the maintenance door of the crushing box 9 can be opened, the large particles can be taken out and put back into the feeding funnel 6 for secondary crushing; after the operation is completed, all drive components are turned off, the cleaning mode is started through the control panel 2, and the water pump 38 is used to deliver clean water to rinse the inside of the nozzle 34, the first conveyor belt 30 and the push pipe 14 to avoid material residue clumping.

[0035] Combination Figure 1-6 As shown, in this embodiment, the supporting steel frame 8 is fixed to the base 1 by high-strength bolts. The mounting plate 7, pushing pipe 14, feeding pipe 11 and crushing box 9 are all precisely assembled on the supporting steel frame 8 to ensure the installation accuracy and linkage coordination of each unit. The control panel 2 integrates a PLC controller, which can realize real-time adjustment of various operating parameters and fault alarm.

[0036] In this embodiment, for biomass fiber raw materials with different humidity levels, the heating temperature and running time of the fan 5 can be adjusted through the control panel 2. When the humidity is high, the drying time can be extended and the heating temperature increased, while when the humidity is low, the parameters can be reduced to save energy. At the same time, the speed of the first motor 15 can be adjusted according to the raw material feed rate to match the pushing speed of the spiral pusher 13 with the feeding speed, so as to avoid the accumulation of materials in the pusher tube 14.

[0037] In this invention: During operation, biomass fiber raw materials are first fed into the feed funnel 6. The raw materials fall onto the first conveyor belt 30 with drainage holes. The control panel 2 starts the water pump 38, which transports water from the water tank 37 to the fixed pipe 33. The raw materials on the conveyor belt are thoroughly rinsed through the evenly distributed nozzles 34 at the bottom. Wastewater is discharged through the drainage holes. The cleaned raw materials smoothly enter the push pipe 14 through the sliding plate 35. Then, the first motor 15 drives the spiral push rod 13 to rotate, evenly pushing the raw materials to the discharge pipe 11. When the blower 5 is started, the hot air generated by its internal heating wire is sent into the feed pipe 11 through the air inlet pipe 12 with a check valve to dry the raw materials. The drain hole at the bottom of the feed pipe 11 can drain the water condensed during the drying process. During this period, the second motor 16 drives the rotating shaft 19 and the striking cam 20 to rotate. The cam repeatedly strikes the striking plate 18, causing the striking rod 22 to move up and down under the action of the return spring 21, continuously striking the bottom of the feed pipe 11, which not only prevents the raw materials from clogging, but also makes the raw materials shake to improve the uniformity of drying.

[0038] After drying, the raw materials enter the crushing box 9 through the receiving funnel 10. After the third motor 24 starts, it drives a pair of crushing rollers 23 to rotate synchronously through two meshing linkage gears 29 to crush the raw materials evenly. The materials that meet the particle size requirements fall into the feeding pipe 27 after being screened by the screening screen 25. In the quantitative feeding stage, the fourth motor 28 drives the rotating disk 42 to rotate. Through the double-section connecting rod 41, it drives the movable block 39 to slide back and forth on the fixed block 43, thereby driving the sealing plate 40 to move left and right in the movable hole at the junction of the fixed box 26 and the feeding pipe 27, realizing the repeated opening and closing of the discharge port of the feeding pipe 27, so that the material falls evenly onto the second conveyor belt 3 with the partition plate 4. The independent area formed by the partition plate 4 ensures the quantitative feeding effect, and finally completes the entire continuous processing process.

[0039] The contents not described in detail in this specification are prior art known to those skilled in the art. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
