Description
Technical Field
[0001] This utility model relates to the field of powder conveying, and more specifically, to a powder conveying mechanism. Background Technology
[0002] In order to achieve automated transfer of powder materials, reduce manual handling, and improve the efficiency and smoothness of the production line, powder conveying devices are usually used in large powder plants and food processing plants to change the problem of time-consuming and labor-intensive traditional manual handling of powder materials.
[0003] Powder conveying devices are specialized equipment used in the food processing industry to transport powders. They can efficiently and safely transfer powders from one location to another and are commonly found in production scenarios such as powder factories, pasta processing plants, and bakeries. However, existing powder conveying mechanisms are prone to powder clumping during the powder conveying process, which can cause material jams and blockages, affecting conveying efficiency and making it impossible to ensure uniform powder feeding.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a powder conveying mechanism to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] The powder conveying mechanism includes a powder hopper, a finished product metering tank at the bottom of the powder hopper, and a pneumatic valve at the bottom of the finished product metering tank via two sets of loose flanges. A metal hose is connected to the bottom of one set of loose flanges, and a transition hopper is connected to the bottom of the metal hose. A powder dispersing and conveying assembly is installed inside the transition hopper. A processing box is installed at the bottom of the powder dispersing and conveying assembly, and a post-processing conveying assembly is installed at the bottom of the processing box.
[0008] Furthermore, in order to dynamically control the powder flow rate in the metal hose 1 through the feeding metering controller and prevent the powder from stagnating or accumulating in the metal hose 1, a feeding metering controller is installed in the metal hose 1, and a loose flange 1 is installed at the bottom of the metal hose 1.
[0009] Furthermore, after the powder is conveyed to the transition hopper through the metal hose, the unagglomerated powder falls through the filter plate into the processing box for subsequent processing, while the agglomerated powder generates strong kinetic energy under the action of the high-speed rotating airflow nozzle, forming a continuous impact and dispersion effect on the powder in the transition hopper, breaking up the agglomerated powder. At the same time, the high-speed rotating airflow nozzle provides additional driving force to the powder through high-speed airflow. After being broken up, it is conveyed to the finished product screw output mechanism and collected through the powder filling outlet. The powder breaking and conveying assembly includes a filter plate installed inside the transition hopper, with a finished product screw output mechanism on one side of the filter plate and a powder filling outlet at the bottom of the finished product screw output mechanism; a dough breaking box is installed on one side of the transition hopper, and a high-speed rotating airflow nozzle is installed inside the dough breaking box.
[0010] Furthermore, in order to vibrate the processing box under the action of two sets of vibrating motors, prevent the powder from clumping or accumulating in the processing box, facilitate the movement of the powder inside the metal hose II in the later stage, break the static adhesion of the powder, maintain fluidity, and promote uniform powder feeding, the post-processing conveying assembly includes vibrating motors installed on both sides of the processing box. The bottom of the processing box is provided with two sets of connecting pipes. The bottom of the connecting pipes is provided with a loose flange II. The bottom of the loose flange II is provided with a metal hose II. The bottom of the metal hose II is provided with a dispensing outlet.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. By setting up a finished product metering tank and a feeding metering controller, this utility model can not only ensure the stable flow of powder and avoid excessive or insufficient material during the feeding process, but also dynamically control the flow rate of powder in the metal hose to prevent powder from stagnating or accumulating in the metal hose.
[0013] 2. This utility model, by setting up a powder dispersing and conveying component, allows the powder to be conveyed to the transition hopper through a metal hose. Unclumped powder falls into the processing box through a filter plate for subsequent processing, while powder with clumps generates strong kinetic energy under the action of a high-speed rotating airflow nozzle, which continuously impacts and disperses the powder in the transition hopper, breaking up the clumps. At the same time, the high-speed rotating airflow nozzle provides additional driving force to the powder through high-speed airflow. After dispersing, the powder is conveyed to the finished product screw output mechanism and collected through the powder filling outlet.
[0014] 3. This utility model, by setting up a post-processing conveying component, can vibrate the processing box under the action of two sets of vibrating motors, to prevent powder from clumping or accumulating in the processing box, to facilitate the movement of powder inside the metal hose II in the later stage, to break the static adhesion of powder, maintain fluidity, and promote uniform powder feeding.

[0022] According to an embodiment of the present invention, a powder conveying mechanism is provided.
[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-3As shown, the powder conveying mechanism according to an embodiment of the present utility model includes a powder hopper 1, a finished product metering tank 2 is provided at the bottom of the powder hopper 1, and a pneumatic valve 4 is provided at the bottom of the finished product metering tank 2 through two sets of loose flanges 3. A metal hose 5 is provided at the bottom of one set of loose flanges 3, and a transition hopper 6 is connected to the bottom of the metal hose 5. A powder dispersing and conveying assembly 7 is provided inside the transition hopper 6, a processing box 8 is provided at the bottom of the powder dispersing and conveying assembly 7, and a post-processing conveying assembly 9 is provided at the bottom of the processing box 8.
[0024] In one embodiment, the metal hose 5 is provided with a feeding metering controller 10 and a loose flange 3 at the bottom end of the metal hose 5. The powder flow rate in the metal hose 5 can be dynamically controlled by the feeding metering controller 10 to prevent the powder from stagnating or accumulating in the metal hose 5.
[0025] In one embodiment, the powder dispersing and conveying assembly 7 includes a filter plate 11 installed inside the transition hopper 6. A finished product screw output mechanism 12 is provided on one side of the filter plate 11, and a powder filling outlet 13 is provided at the bottom end of the finished product screw output mechanism 12. A dough dispersing box 14 is provided on one side of the transition hopper 6, and a high-speed rotating airflow nozzle 15 is provided inside the dough dispersing box 14. After the powder is conveyed to the transition hopper 6 through the metal hose 5, the unagglomerated powder falls into the processing box 8 through the filter plate 11 for subsequent processing. The powder with agglomerates generates strong kinetic energy under the action of the high-speed rotating airflow nozzle 15, which forms a continuous impact and dispersion effect on the powder in the transition hopper 6, dispersing the agglomerated powder. At the same time, the high-speed rotating airflow nozzle 15 provides additional driving force to the powder through high-speed airflow. After dispersing, it can be transmitted to the finished product screw output mechanism 12 and collected through the powder filling outlet 13.
[0026] In one embodiment, the post-processing conveying assembly 9 includes vibration motors 16 installed on both sides of the processing box 8. The bottom of the processing box 8 is provided with two sets of connecting pipes 17. The bottom of the connecting pipes 17 is provided with a loose flange 18. The bottom of the loose flange 18 is provided with a metal hose 19. The bottom of the metal hose 19 is provided with a dispensing outlet 20. Thus, the processing box 8 can be vibrated under the action of the two sets of vibration motors 16 to prevent powder from clumping or accumulating in the processing box 8, facilitate the movement of powder in the metal hose 19 in the later stage, break the static adhesion of powder, maintain fluidity, and promote uniform powder feeding.
[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0028] In practical applications, the powder is fed from the powder hopper 1 into the finished product metering tank 2. The finished product metering tank 2 accurately measures the amount of powder to ensure a stable flow rate and avoid over- or under-feeding. The powder flows through the pneumatic valve 4 into the metal hose 5. The powder flow rate is controlled by the feeding metering controller 10 in the metal hose 5 to prevent the powder from stagnating or accumulating in the metal hose 5. After passing through the metal hose 5, the powder falls into the transition hopper 6. The powder that meets the requirements and is not agglomerated will first fall into the processing box through the filter plate 11.
[0029] When powder clumps, the high-speed rotating airflow nozzle 15 is activated. The high-speed rotating airflow generated by the high-speed rotating airflow nozzle 15 brings strong kinetic energy, which continuously impacts and disperses the powder in the transition hopper 6, breaking up the clumps and maintaining the flowability of the material. For the broken powder, the high-speed rotating airflow nozzle 15 also provides additional driving force to the powder. After being broken up, it is transferred to the finished product screw output mechanism 12 and collected through the powder filling outlet 13. During the conveying process, the airflow ejected from the high-speed rotating airflow nozzle 15 forms turbulence in the transition hopper 6, reducing the frictional resistance between the powder and the finished product screw output mechanism 12, improving the conveying conditions of the powder in the finished product screw output mechanism 12, and preventing the powder from stagnating or being poorly conveyed due to excessive resistance.
[0030] The powder that falls into the processing box 8 in the early stage falls into the metal hose 19 and is collected through the dispensing outlet 20. During the dispensing process, the processing box 8 can be vibrated by two sets of vibration motors 16 to prevent the powder from clumping or accumulating in the processing box 8, to facilitate the movement of the powder inside the metal hose 19, to break the static adhesion of the powder, to maintain fluidity, and to promote uniform powder feeding.
[0031] It should be noted that the high-speed rotating airflow nozzle 15 disperses the powder by using the impact, shearing and disturbance of the high-speed airflow. The high-speed rotating airflow nozzle 15 generates a high-pressure airflow through a compressed air source (such as an air compressor). The airflow is sprayed at high speed through a special nozzle to form a high-kinetic-energy airflow jet. The airflow impacts the powder clumps at extremely high speed, subjecting them to strong kinetic energy, resulting in the separation and crushing of the particles.
[0032] The high-speed rotating airflow nozzle 15 is driven mainly by the airflow generating device and nozzle design. The compressor compresses the ambient air to a high pressure, usually in the range of 0.6-0.8MPa (6-8bar). The pressure energy of the gas is converted into kinetic energy through the nozzle to form a high-speed airflow.
[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, the present utility model, through the setting of the finished product metering tank 2 and the feeding metering controller 10, can not only ensure the stable flow of powder and avoid excessive or insufficient material during the feeding process, but also dynamically control the flow rate of powder in the metal hose-5, preventing powder from stagnating or accumulating in the metal hose-5. By setting the powder dispersing and conveying component 7, after the powder is conveyed to the transition hopper 6 through the metal hose-5, the un-clumped powder falls into the processing box 8 through the filter plate 11 for subsequent processing, while the clumped powder generates strong kinetic energy under the action of the high-speed rotating airflow nozzle 15, forming a continuous impact and dispersing effect on the powder in the transition hopper 6, breaking up the clumped powder. At the same time, the high-speed rotating airflow nozzle 15 provides additional driving force to the powder through high-speed airflow. After dispersing, the powder is conveyed to the finished product spiral output mechanism 12 and collected through the powder filling outlet 13. This invention, by setting up a post-processing conveying component 9, can vibrate the processing box 8 under the action of two sets of vibration motors 16, to prevent powder from clumping or accumulating in the processing box 8, to facilitate the movement of powder inside the metal hose 19 in the later stage, to break the static adhesion of powder, to maintain fluidity, and to promote uniform powder feeding.
