Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of biomass material and rubber composite production, specifically relates to a kind of biomass short fiber and liquid rubber pretreatment device. BACKGROUND

[0002] In the production process of biomass material and rubber composite material, pretreatment of biomass short fiber and liquid rubber is a crucial step. Biomass short fiber is usually derived from natural fiber, such as wood fiber, bamboo fiber, etc. They are used as reinforcing materials mixed with liquid rubber to improve the performance and sustainability of the composite material. The pretreatment process involves the transportation, dispersion and mixing of biomass short fiber with liquid rubber, which is crucial for ensuring the quality and performance of the final product.

[0003] Existing pretreatment technology usually involves feeding biomass short fiber into a mixing container through mechanical transportation, and then adding liquid rubber. This method includes the following steps or equipment: biomass short fiber is fed into a mixing tank using a conveyor belt or screw conveyor. Liquid rubber is transported into the mixing tank by pumping or other mechanical means. In the mixing tank, mechanical stirring is carried out by a stirrer to achieve the mixing of fiber and rubber. The existing mechanical stirring method may not ensure uniform dispersion of biomass short fiber in liquid rubber, which may lead to agglomeration and affect the performance of the composite material. The process of mechanical transportation and stirring may be relatively slow, resulting in low efficiency of the entire pretreatment process and affecting production speed. During the transportation of biomass short fiber, due to the lack of effective dispersion and transportation mechanism, fiber loss and breakage may occur, affecting the utilization rate of raw materials.

[0004] In view of this, a biomass short fiber and liquid rubber pretreatment device is proposed to solve the above problems by wind force feeding and precise stirring to improve the quality and efficiency of the pretreatment process. SUMMARY

[0005] The present invention aims to solve the technical problems of the existing biomass short fiber and liquid rubber pretreatment technology in terms of mixing uniformity, efficiency, loss, safety and stability.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A biomass short fiber and liquid rubber pretreatment device, comprising a mixing tank and a wind force feeder, the mixing tank is provided with a feeding port A for feeding liquid rubber and a feeding port B for feeding biomass short fiber; the wind force feeder is used to feed biomass short fiber into the feeding port A by wind force blowing, so as to disperse the biomass short fiber into the mixing tank;

[0008] The pneumatic feeder includes a feeding hopper, a screw conveyor, a blower, and a feeding pipe. The discharge port A at the bottom of the feeding hopper is connected to the inlet A on the screw conveyor. The discharge port B of the screw conveyor is connected to the inlet B of the feeding pipe. The air inlet on the feeding pipe is connected to the air outlet of the blower. The feeding hopper extends upward and is connected to the feeding port B.

[0009] Preferably, the mixing tank is mounted on the support using four mounting feet arranged in a ring at equal intervals. The equal spacing of the four mounting feet ensures the stability of the mixing tank on the support, preventing shaking caused by stirring or external factors during the mixing process.

[0010] Preferably, the fan and screw conveyor are fixed to the mounting base, which is fixed to the bottom wall of the support frame. Fixing the fan and screw conveyor to the mounting base can reduce vibration during operation and ensure the stability of the entire system.

[0011] Preferably, the feed port B has a threaded outlet with a flared discharge port located inside the mixing tank. The flared discharge port helps to better guide the short biomass fibers and prevents clogging during feeding. The flared discharge port also promotes uniform distribution of the material within the mixing tank, improving mixing efficiency.

[0012] Preferably, the outer side of the hopper is equipped with a hopper frame fixed to the support. The hopper frame can provide additional support for the hopper and enhance the stability of the entire feeding system.

[0013] Preferably, the top of the feeding hopper is covered with a cover plate, which slides and is guided inside a rectangular guide frame. The rectangular guide frame is provided with a U-shaped limiting rod that is pulled out to match the cover plate. The cover plate is limited to the top of the feeding hopper or the limiting of the cover plate is released by pulling out the U-shaped limiting rod.

[0014] The rectangular guide frame is connected to the bracket on both sides by support rods.

[0015] The sliding guide and limiting design of the cover plate allows operators to easily open and close the top of the hopper. The rectangular guide frame design ensures precise positioning of the cover plate when closing the hopper, maintaining its sealing performance. The connection between the support rod and the bracket enhances the structural stability of the rectangular guide frame, ensuring the reliability of the entire feeding system.

[0016] Preferably, the bottom of the mixing tank is equipped with a discharge port with a valve. The discharge port with a valve can precisely control the discharge speed and amount of material, avoiding waste or overflow caused by material flowing out too quickly.

[0017] Preferably, a servo geared motor is installed at the top of the mixing tank, and an agitator is rotatably connected inside the mixing tank. The output shaft of the servo geared motor is drive-connected to the input shaft of the agitator. The servo geared motor can provide precise speed control, ensuring that the agitator operates at a predetermined speed and angle to achieve the best mixing effect.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are:

[0019] This pretreatment device for biomass short fibers and liquid rubber is mainly based on a combination of pneumatic feeding and mechanical conveying. The mixing tank, as the core mixing container, receives liquid rubber and biomass short fibers through two feed ports. The biomass short fibers first enter the feed hopper, then pass through a screw conveyor and feed pipe, where airflow generated by a blower blows them to feed port B of the mixing tank, achieving material dispersion and mixing.

[0020] The effective dispersion of the pneumatic feeder prevents the agglomeration of short biomass fibers, reduces losses during transport, and improves raw material utilization. The closed-system design also reduces dust and harmful gas emissions, improving the safety of the working environment. Overall, this device improves the efficiency of the pretreatment process, reduces waste, enhances operational stability, and provides an efficient and environmentally friendly solution for mixing biomass materials with liquid rubber.

[0027] 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.

[0028] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0029] This application discloses a pretreatment device for biomass short fibers and liquid rubber, including a mixing tank 1 and a pneumatic feeder 4. The mixing tank 1 is mounted on a support 16 by four mounting feet 15 arranged in a ring at equal intervals. The equal-distance arrangement of the four mounting feet 15 ensures the stability of the mixing tank 1 on the support 16, preventing shaking caused by stirring or external factors during the mixing process. The equal-distance arrangement also helps maintain the symmetry of the mixing tank 1, resulting in a more uniform mixing effect during operation. The design of the mounting feet 15 makes the installation and disassembly of the mixing tank 1 more convenient. The ring-shaped mounting feet 15 design increases the structural strength of the connection between the mixing tank 1 and the support 16.

[0030] The mixing tank 1 is equipped with a feeding port A2 for feeding liquid rubber and a feeding port B3 for feeding biomass short fiber;

[0031] The bottom of the mixing tank 1 is equipped with a discharge port 24 with a valve. The discharge port 24 with the valve allows for precise control of the material discharge speed and quantity, preventing waste or overflow caused by excessively rapid material flow. It allows for rapid discharge of the mixed material from the mixing tank 1, improving production efficiency. The valve design ensures that material will not accidentally flow out when not in operation, enhancing operational safety.

[0032] A servo geared motor 25 is installed on the top of the mixing tank 1. An agitator is rotatably connected inside the mixing tank 1, and the output shaft of the servo geared motor 25 is drive-connected to the input shaft of the agitator. The servo geared motor 25 can provide precise speed control, ensuring that the agitator operates at a predetermined speed and angle to achieve the best mixing effect. The agitator is designed to effectively promote the mixing of materials in the mixing tank 1, improving mixing uniformity and efficiency.

[0033] The pneumatic feeder 4 is used to feed biomass short fibers to the feeding port A2 by pneumatic blowing, so as to disperse the biomass short fibers into the mixing tank 1;

[0034] The pneumatic feeder 4 includes a feeding hopper 5, a screw conveyor 6, a blower 7, and a feeding pipe 8. The blower 7 and screw conveyor 6 are fixed to a mounting base 17, which is fixed to the bottom wall of a support 16. Fixing the blower 7 and screw conveyor 6 to the mounting base 17 reduces vibration during operation and ensures the stability of the entire system. The mounting base 17 helps reduce mechanical wear caused by vibration, extending the equipment's service life. The fixed installation method reduces the risk of accidental injury caused by equipment movement.

[0035] The discharge port A9 at the bottom of the feeding hopper 5 is connected to the inlet A10 on the screw conveyor 6. The discharge port B11 of the screw conveyor 6 is connected to the inlet B12 of the feeding pipe 8. The air inlet 13 on the feeding pipe 8 is connected to the air outlet 14 of the blower 7. The feeding hopper 5 extends upward and is connected to the feeding port B3.

[0036] The feed port B3 has a threaded outlet with a flared outlet 18 located inside the mixing tank 1. The flared outlet 18 helps to better guide the short biomass fibers and prevents clogging during feeding. The flared outlet 18 also helps to distribute the material evenly within the mixing tank 1, improving the mixing effect.

[0037] The outer side of the feeding hopper 5 is equipped with a hopper frame 19 fixed to the bracket 16. The hopper frame 19 provides additional support for the feeding hopper 5, enhancing the stability of the entire feeding system. The hopper frame 19 also provides some protection, preventing the feeding hopper 5 from falling off or shifting in case of accidents. The hopper frame 19 helps to better utilize space and maintain a clean and orderly production site.

[0038] The top of the feeding hopper 5 is covered with a cover plate 20. The cover plate 20 is slidably guided on the inside of the rectangular guide frame 21. The rectangular guide frame 21 is provided with a U-shaped limiting rod 22 that cooperates with its pull-out. By pulling out the U-shaped limiting rod 22, the cover plate 20 is limited to the top of the feeding hopper 5 or the limitation on the cover plate 20 is released.

[0039] The two sides of the rectangular guide frame 21 are connected to the bracket 16 via support rods 23.

[0040] The sliding guide and limiting design of the cover plate 20 allows operators to easily open and close the top of the feeding hopper 5. The design of the rectangular guide frame 21 ensures that the cover plate 20 can be precisely positioned when closing the feeding hopper 5, maintaining the sealing performance of the feeding hopper 5. The connection between the support rod 23 and the bracket 16 enhances the structural stability of the rectangular guide frame 21, ensuring the reliability of the entire feeding system.

[0041] This pretreatment unit for biomass short fibers and liquid rubber primarily utilizes a combination of pneumatic feeding and mechanical conveying. Mixing tank 1 is the main container for mixing the biomass short fibers and liquid rubber. It has two inlets, inlet A2 and inlet B3. The liquid rubber enters mixing tank 1 through inlet A2. This is typically achieved through pumping or other mechanical means.

[0042] Biomass short fibers are fed into mixing tank 1 via pneumatic feeder 4. The specific process is as follows: Biomass short fibers first enter feeding hopper 5, and through discharge port A9 at the bottom of feeding hopper 5, they are fed into inlet A10 of screw conveyor 6. Screw conveyor 6 is responsible for conveying biomass short fibers to discharge port B11. Discharge port B11 is connected to inlet B12 of feeding pipe 8, and biomass short fibers continue to move upward along feeding pipe 8. Air inlet 13 of feeding pipe 8 is connected to air outlet 14 of blower 7, and the airflow generated by blower 7 blows biomass short fibers to feeding port B3 of mixing tank 1. Through feeding port B3, biomass short fibers are dispersed and fed into the interior of mixing tank 1.

[0043] Pneumatic feeding effectively disperses biomass short fibers, preventing agglomeration and improving mixing efficiency. Combining mechanical and pneumatic feeding increases the feeding speed of biomass short fibers, thereby improving the overall efficiency of the pretreatment process. Pneumatic feeding also reduces fiber loss during transport, ensuring high raw material utilization. The entire pretreatment process is conducted within a closed system, reducing dust and harmful gas emissions and improving the safety of the working environment.

[0044] This pretreatment device for biomass short fibers and liquid rubber employs a combination of pneumatic feeding and mechanical conveying. The mixing tank 1, serving as the core mixing container, has two feeding ports, one for liquid rubber and the other for biomass short fibers. Liquid rubber is pumped or fed into feeding port A2 via other mechanical means, while biomass short fibers are fed in via a pneumatic feeder 4. Specifically, the biomass short fibers first enter the feeding hopper 5, then pass through the screw conveyor 6 and feeding pipe 8, and are finally blown by the airflow generated by the blower 7 to the feeding port B3 of the mixing tank 1, achieving material dispersion and mixing.

[0045] The design of this device ensures the stability of the mixing tank 1 on the support 16. The connection strength is enhanced by the equidistantly arranged mounting feet 15 and the annular structure, allowing the mixing tank 1 to maintain a uniform mixing effect during operation, while also facilitating installation and disassembly. Furthermore, precise speed control of the agitator and adjustment of the stirring angle improve mixing uniformity and efficiency.

[0046] The discharge port 24 with a valve at the bottom of the mixing tank 1 allows for precise control of the material discharge speed and amount, reducing waste and improving production efficiency. It also ensures that materials will not accidentally leak out during non-operational periods, increasing work safety. The sliding guide and limit design of the feeding hopper 5 allows operators to easily open and close the top cover 20, maintaining the sealing performance of the feeding hopper 5 and enhancing the stability of the entire feeding system.

[0047] The pneumatic feeder 4 effectively disperses biomass short fibers, preventing agglomeration, reducing losses during transport, and improving raw material utilization. Simultaneously, the enclosed system design reduces dust and harmful gas emissions, improving the safety of the working environment. The hopper frame 19 further enhances the stability of the feeding system and helps maintain a clean and orderly production site.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
