Description

Technical Field

[0001] The invention relates to the technical field of cellulose powder production, in particular to a cellulose crushing and throwing device. Background Art

[0002] As an important biomass resource, cellulose is widely used in food, medicine, chemical industry and other fields. In the process of cellulose processing, the cellulose crushing and throwing device is used to crush the cellulose and throw it into storage or further processing. However, the traditional cellulose crushing and throwing device mainly relies on the crushing knife roller to crush the cellulose, and the mechanical power generated is used to throw the cellulose powder into the conveying trough. In order to get the powder to the target location, it is usually combined with a conveyor belt or other open pipeline transportation methods. However, there are obvious defects in the design, which are mainly manifested in the following aspects:

[0003] Environmental pollution: The traditional cellulose crushing and throwing device adopts an open throwing design. The powder is easy to leak and spread in the air during the pipeline transportation process, causing serious pollution. This not only has an adverse impact on the production environment, but also may threaten the health of operators. Since cellulose powder is fine particles, long-term exposure to hazards may cause safety problems and increase safety hazards during operation. In addition, the scattered powder also increases the cleaning and maintenance costs and affects production efficiency.

[0004] Raw materials: Due to the lack of effective sealing measures, a large amount of cellulose powder leaks out during pipeline transportation, resulting in a waste of raw materials. The cellulose powder after crushing is small and light, and it is difficult to control its flow direction, especially in an open environment, it is easily consumed and dispersed by the airflow, and cannot be effectively transported to the designated location. Supply waste not only increases production costs, but also reduces overall production efficiency.

[0005] Low conveying efficiency: Traditional devices rely on mechanical power and conveyor belts to transport cellulose powder through pipelines, but their pipeline transportation efficiency is low. Due to the lack of accurate terminal control, the throwing distance and direction of cellulose powder are difficult to adjust, resulting in the powder being dispersed or accumulated during the transportation process, affecting the final transportation effect. At the same time, the use of conveyor belts increases the complexity of the system, occupies more space, and is prone to blockage and other problems, affecting continuous production.

[0006] Inflexible control of throwing direction: The throwing direction of traditional cellulose crushing throwing devices is fixed and cannot be flexibly adjusted according to actual needs. This design limits the application of the device in different production scenarios, especially when precise delivery to target locations is required for different situations. Traditional equipment cannot meet production needs, resulting in poor throwing accuracy and low work efficiency.

[0007] In summary, traditional cellulose crushing and throwing devices have problems such as environmental pollution, waste of raw materials, low pipeline transportation efficiency, and uncontrollable throwing direction. An improved device is urgently needed to solve these technical defects, optimize the cellulose crushing and throwing process, improve production efficiency, and reduce the impact on the environment. Summary of the invention

[0008] The present invention aims to solve the problems of environmental pollution, raw material waste and low pipeline transportation efficiency existing in the cellulose crushing and throwing device in the prior art, and to provide a cellulose crushing and throwing device with optimized structure, stable pipeline transportation and accurate throwing.

[0009] To this end, the technical solution adopted in the present invention is:

[0010] A cellulose crushing and throwing device comprises a control base, an air-powder mixing mechanism, a powder throwing mechanism and a flexible connecting pipe; the air-powder mixing mechanism is installed on the control base, and its top surface is connected to the powder throwing mechanism through a flexible connecting pipe and can be adjusted. The air-powder mixing mechanism provides airflow through an air inlet seat, and finally enters a mixing chamber through an aeration cylinder. Aeration holes are arranged inside the mixing chamber, and finally the air is fully mixed with cellulose powder. The powder throwing mechanism accelerates the air-powder mixture through a multi-stage axial flow impeller, and controls the angle of the beam nozzle by adjusting the steering gear to achieve directional throwing of the air-powder mixture.

[0011] Based on this technology, the cellulose crushing and throwing device of the present invention can realize an efficient conveying scheme of cellulose powder by correcting the airflow and assisting the high-speed axial flow impeller, and at the same time significantly improve the throwing accuracy and work efficiency by precisely controlling the throwing direction and angle.

[0012] In a preferred example of the present invention, the air-powder mixing mechanism includes an aeration cylinder, an air inlet seat and an air distribution assembly. The air inlet seat is fixed to the bottom end of the aeration cylinder. The air distribution assembly includes a first air distribution ring and a second air distribution ring. A cyclone air nozzle is arranged inside the first air distribution ring, and an excitation air nozzle is arranged inside the second air distribution ring. Finally, the powder is blown into the mixing chamber through these cyclone air nozzles and the excitation air nozzle to fully mix the powder.

[0013] The present invention ensures that the cellulose powder is evenly mixed in the mixing chamber through the swirl flow and the exciting air nozzle generated by the air distribution component, avoids powder deposition, and effectively improves the mixing efficiency.

[0014] In another preferred example, the powder throwing mechanism includes a jet cylinder, a booster cylinder and a beam nozzle. Several axial flow impellers are installed in the middle of the booster cylinder. The axial flow impellers are driven by a motor to accelerate the gas-powder mixture. The beam nozzle is used to further adjust the ejection direction and angle of the gas-powder mixture.

[0015] The working effect of the present invention is that the multi-stage axial flow impeller in the booster cylinder can accelerate the gas-powder mixture step by step, improve the momentum of the thrown material, so that the cellulose powder can be efficiently and directionally thrown to the specified position, avoid the dispersion of the thrown material, and improve the accuracy of the thrown material and the stability of pipeline transportation.

[0016] Through the above improvements, the present invention effectively solves the problems of environmental pollution, raw material waste and low throwing efficiency existing in the traditional cellulose crushing and throwing device, and significantly improves the working efficiency, accuracy and environmental protection performance of the device.

[0017] The good effects achieved by the present invention are:

[0018] 1. In the present invention, by adopting the design of flexible connecting pipe and closed air-powder mixing mechanism, the leakage of powder caused by open throwing in the traditional cellulose crushing and throwing device is effectively avoided, thereby reducing the pollution to the environment. In addition, the closed structure reduces the loss of powder, reduces the waste of raw materials, significantly improves the utilization efficiency of raw materials, ensures that the powder can accurately reach the target area during the entire throwing and conveying process, and avoids ineffective waste and pollution.

[0019] 2. In the present invention, through the ingenious combination of multi-stage axial flow impeller and swirl air nozzle, the airflow and powder can form a stable swirl effect in the mixing chamber, thereby greatly improving the mixing uniformity of the powder and airflow. This design not only optimizes the projection effect of cellulose powder, but also enables the powder to always maintain a uniform state during pipeline transportation, effectively solving the problem of low efficiency of pipeline transportation of traditional cellulose powder devices, and improving the stability and overall efficiency of pipeline transportation of cellulose.

[0020] 3. In the present invention, the powder throwing mechanism is equipped with an adjustable angle design, which, combined with a customized control system, can achieve precise control of the throwing direction and angle. By adjusting the horizontal and vertical angles of the throwing device, it is ensured that the cellulose powder can be accurately thrown to the specified position according to work requirements, which greatly improves the accuracy of cellulose throwing. At the same time, by adjusting the throwing momentum of the gas-powder mixture, the energy utilization efficiency in the throwing process is further optimized, solving the problems of insufficient throwing accuracy and inflexible direction control of traditional equipment.

[0034] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific implementations and attached drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Example

[0035] like Figures 1 to 8 As shown, the present invention provides a cellulose crushing and throwing device, comprising a control base 100, an air-powder mixing mechanism 200, a powder throwing mechanism 300 and a flexible connecting pipe 400. The device realizes efficient pipeline transportation and throwing of cellulose powder by mixing airflow and powder, accelerating delivery and directional throwing.

[0036] Control base 100: A drive base 110 is installed on the control base 100, and a vertical axis support rod 111 and an angle adjustment support rod 112 are arranged at the output end of the drive base 110. The vertical axis support rod 111 is used to support and control the horizontal rotation of the powder throwing mechanism 300, and the angle adjustment support rod 112 is used to adjust the vertical angle of the powder throwing mechanism 300. The drive base 110 drives the vertical axis support rod 111 and the angle adjustment support rod 112 through the steering gear to perform precise angle control, so that the powder throwing mechanism 300 can flexibly adjust the throwing direction.

[0037] Air-powder mixing mechanism 200: The air-powder mixing mechanism 200 is fixedly mounted on the control base 100, and mainly includes an aeration cylinder 210, an air inlet seat 220, an air distribution assembly 230, and a mixing chamber 240. The air inlet seat 220 provides airflow through the aeration cylinder 210, and the airflow enters from the bottom of the air inlet seat 220, and a continuous and stable airflow is provided through the connected external air pump. A powder guide hopper 211 is provided on the surface of the aeration cylinder 210, which is used to guide cellulose powder into the mixing chamber 240. A plurality of evenly distributed aeration holes 241 are provided on the inner wall of the mixing chamber 240, and the airflow is fully mixed with the powder in the mixing chamber 240 through the aeration holes 241.

[0038] The air distribution assembly 230 includes a first air distribution ring 231 and a second air distribution ring 232. The first air distribution ring 231 is provided with a plurality of cyclone air nozzles 233, which are evenly distributed tangentially in the mixing chamber 240 to form a rotating airflow and promote the full mixing of the powder. The second air distribution ring 232 is provided with a plurality of excitation air nozzles 234, and the airflow is blown vertically from the excitation air nozzles 234 to the bottom of the mixing chamber 240 to prevent the powder from gathering at the bottom and improve the mixing effect of the powder. Through this air distribution method, the cellulose powder and the airflow are efficiently and evenly mixed in the mixing chamber 240.

[0039] Powder throwing mechanism 300: The powder throwing mechanism 300 includes a jet tube 310, a nozzle seat 340, a booster tube 330, a motor 320 and a steering gear 350. A plurality of axial flow impellers 331 are installed in the booster tube 330, and the axial flow impellers 331 are driven to rotate by the motor 320 to accelerate the gas-powder mixture in the booster tube 330. The booster tube 330 has a conical structure, and the inner diameter gradually shrinks along the airflow direction, thereby limiting and guiding the gas-powder mixture to prevent the mixture from being dispersed during the throwing process.

[0040] The nozzle seat 340 is installed at the front end of the injection tube 310, and the nozzle seat 340 is movably connected to the bundle nozzle 341, which is used to accurately control the injection direction of the gas-powder mixture. The direction-adjusting servo 350 is installed in the injection tube 310, and the output end of the direction-adjusting servo 350 is connected to the bundle nozzle 341 through the linkage rod 351. The rotation of the direction-adjusting servo controls the angle deflection of the bundle nozzle 341 to achieve accurate control of the throwing direction and angle. This design ensures that the cellulose powder is accurately thrown to the specified position, ensuring the accuracy of the throwing.

[0041] Flexible connecting pipe 400: The flexible connecting pipe 400 is used to connect the gas-powder mixing mechanism 200 and the powder throwing mechanism 300, ensuring that the gas-powder mixture can maintain stable pipeline transportation when the direction and angle of the powder throwing mechanism 300 are adjusted. The design of the flexible connecting pipe 400 allows greater flexibility during the operation of the powder throwing mechanism 300, while ensuring the continuity and stability of the flow.

[0042] System: The control base 100 and the steering servo 350 are equipped with a control system for adjusting the horizontal and vertical angles of the powder throwing mechanism 300 and controlling the motor 320, thereby accurately controlling the throwing momentum and throwing distance of the gas-powder mixture. The control system monitors the state of the gas-powder mixture in real time through sensors, and automatically adjusts the throwing parameters according to feedback to improve the efficiency and accuracy of the throwing. In addition, the control system can communicate with external monitoring equipment to achieve remote monitoring and adjustment. The operator can remotely adjust the direction, angle and distance of the throwing as needed, which greatly improves the flexibility of operation. Example

[0043] In another example, a gap is set between the mixing chamber 240 and the aeration cylinder 210 so that the gas can enter the mixing chamber 240 from the periphery and the axis. This double air intake method further improves the mixing effect of the gas and the powder, ensuring that the cellulose powder is evenly mixed during the pipeline transportation process, and avoiding the problem of powder aggregation. In addition, the multi-stage axial flow impeller 331 in the booster cylinder 330 is arranged in a continuous sequence along the booster cylinder 330, which can accelerate the gas-powder mixture step by step, effectively control the momentum of the thrown material, and make the throwing process more stable and uniform. Example

[0044] The device of the present invention is equipped with a remote control system, which is connected to an external monitoring device. The operator can view the working status and material throwing parameters of the device in real time through the remote monitoring system, and make real-time adjustments as needed, such as adjusting the angle of the powder throwing mechanism 300. This function greatly improves the automation and flexibility of production and ensures the accuracy of the material throwing process.
