Description

Technical Field

[0001] The present invention particularly relates to a powdered food conveying device, belonging to the technical field of food processing. Background Art

[0002] In the food processing industry, the conveying of powdered foods (such as milk powder, condiments, flour, etc.) places extremely high demands on hygiene, efficiency, and material loss control. Traditional powder conveying methods, such as screw conveyors and belt conveyors, suffer from issues such as material residue, contamination, and low conveying efficiency, making it difficult to meet the strict hygiene standards and efficient production needs of the food industry. While some pneumatic conveying equipment can increase conveying speeds, they lack air recycling mechanisms, consume high energy, and are prone to causing dust to fly, impacting the workshop environment and operator health. Furthermore, existing equipment often experiences internal wall adhesion and clogging during material conveying, increasing maintenance costs and making it difficult to ensure production continuity.

[0003] Through searching, Chinese patent publication number CN222743405U discloses a belt conveyor device for food processing, comprising: an equipment frame, two pulleys, a motor, and a conveyor belt. Two first protrusions and two adjacent second protrusions form a box-shaped placement position on the outer surface of the conveyor belt, and the raw materials to be conveyed are placed in the placement position. During the conveyor belt transmission process, the raw materials are blocked by the first protrusion and the second protrusion, and can be kept relatively stably in the placement position. In addition, some of the raw materials may enter the first protrusion. During the movement of the conveyor belt, when the placement position passes through the pulley, the first protrusion changes from a straight line to an arc, causing the first protrusion to deform accordingly, so that the raw materials entering the first protrusion can fall more easily. The beneficial effects are: simple structure, stable transmission of granular raw materials, and prevention of raw materials falling from the conveyor belt.

[0004] Regarding the above-mentioned related technologies, the inventors found the following defects: the above-mentioned device is mainly suitable for the transportation of granular raw materials. For powdered materials, due to the obvious differences in their fluidity and adhesion with granular raw materials, the traditional conveyor belt transmission method is difficult to effectively solve the problems of powder accumulation and adhesion, and lacks wind circulation transportation and inner wall cleaning mechanisms for powdered materials, and cannot meet the special needs of powdered food transportation.

[0045] like Figure 1 and Figure 2 The figure shows a powdered food conveying device, comprising a conveyor drum assembly 1. The conveyor drum assembly 1 comprises a conveyor drum body 101 that cooperates with a feeding mechanism 4 to convey material, and a discharge pipe 102 for discharging the material. A base 103 is fixedly connected to the bottom of the conveyor drum body 101, and a first sealing side plate 104 is fixedly mounted on one side of the conveyor drum body 101.

[0046] like Figure 1 and Figure 2 As shown, a feed assembly 2 is mounted on one side of the conveyor drum assembly 1. This assembly comprises a transfer chamber housing 201 positioned between the second bevel gear 406 and the air outlet pipe 302. A feed hopper 202 is fixedly mounted on the top of the transfer chamber housing 201 for feeding powdered material into the interior of the transfer chamber housing 201. Feed hopper 202 facilitates rapid loading by humans or equipment. Transfer chamber housing 201 temporarily stores powdered material and, in conjunction with the wind circulation mechanism 3, bridges the gap between temporary storage and directional conveying.

[0047] like Figures 1 to 3As shown, a wind circulation mechanism 3 is provided on one side of the feeding assembly 2, and the wind circulation mechanism 3 includes an air outlet pipe 302 for blowing gas to the transfer chamber shell 201, a first servo motor 306 for driving the impeller inside the impeller chamber 305 to rotate, and a return pipe 308 for extracting the air inside the conveying cylinder body 101. The wind output by the air outlet pipe 302 blows the powder inside the transfer chamber shell 201 into the interior of the conveying cylinder body 101; the first servo motor 306 drives the impeller to generate a directional airflow, the air outlet pipe 302 converts the airflow into power to push the powder to move, and the return pipe 308 recovers the air in the conveying cylinder to form a closed-loop airflow circulation, thereby reducing energy consumption and maintaining the system air pressure stable.

[0048] like Figure 2 and Figure 3 As shown, the return pipe 308 draws the air inside the conveying cylinder body 101 into the inside of the air inlet chamber housing 307, completing the internal circulation of air from the transfer chamber housing 201 to the impeller chamber 305. The wind circulation mechanism 3 also includes a bracket 301 for fixedly installing the air outlet chamber housing 303 and the air inlet chamber housing 307. The first servo motor 306 is fixedly installed on the top of the bracket 301. A worm gear tube 304 is fixedly installed on one side of the impeller chamber 305. The impeller chamber 305 is connected to the air outlet chamber housing 303 through the worm gear tube 304. The left and right ends of the return pipe 308 are respectively connected to the air inlet chamber housing 307 and the conveying cylinder body 101. The air inlet and air outlet of the impeller chamber 305 are respectively connected to the air inlet chamber housing 307 and the air outlet chamber housing 303. The bracket 301 provides rigid support for the wind circulation mechanism 3, the worm gear 304 guides the airflow to be output smoothly, the air inlet chamber housing 307 and the air outlet chamber housing 303 cooperate with the impeller chamber 305 to form an air flow path, and the return pipe 308 realizes air recycling to ensure the continuity and stability of wind power transmission.

[0049] like Figure 1 and Figure 5As shown, a feeding mechanism 4 is provided on the other side of the feed assembly 2. The feeding mechanism 4 includes a gear transmission assembly for driving the conveying assembly, a flow guide assembly for guiding the flow of powder, and a conveying assembly for conveying powdered materials. The gear transmission assembly of the feeding mechanism 4 includes a motor mounting plate 401 fixedly mounted on the top of the conveying barrel body 101. A second servo motor 402 is fixedly mounted on one side of the motor mounting plate 401. A driving gear 403 is fixedly mounted on the output end of the second servo motor 402. One side of the driving gear 403 meshes with a driven gear 404. The bottom of the driven gear 404 is fixedly connected to a first bevel gear 405. One side of the first bevel gear 405 meshes with the second bevel gear 406, and the other side of the first bevel gear 405 meshes with the third bevel gear 407. The motor mounting plate 401 firmly fixes the second servo motor 402. The gear transmission assembly accurately transmits and divides the motor power. The bevel gear changes the transmission direction, achieving synchronized and coordinated operation of multiple components such as the feeding barrel 408 and the scraper.

[0050] like Figure 6 and Figure 7 As shown, the gear transmission assembly includes a third bevel gear 407 for driving the feed barrel 408 to rotate clockwise and a second bevel gear 406 for driving the second scraper 411 to rotate counterclockwise, the transmission assembly includes a feed barrel 408 for conveying materials and a second scraper 411 for scraping off the powder on the inner wall of the feed barrel 408, and a guide hole 409 is provided on one side of the feed barrel 408. The transmission assembly of the feeding mechanism 4 includes a first scraper 410 fixedly connected to the outer wall of the feed barrel 408, which is used to convey the powder material inside the barrel body 101, and a guide hole 409 is provided on one side of the feed barrel 408. The second scraper 411 includes two groups of spiral scrapers, and the two groups of spiral scrapers are fixedly connected to the second support rod 413 through the first support rod 412, and the setting direction of the first support rod 412 is perpendicular to that of the second support rod 413. When the feeding barrel 408 rotates, the material is pushed through the guide hole 409 and the first scraper 410 on the outer wall. The second scraper 411 rotates in the opposite direction to remove the residual powder on the inner wall. The spiral scraper design enhances the scraping effect, avoids material adhesion and blockage, and ensures the conveying efficiency.

[0051] like Figure 7 and Figure 8As shown, the edges of the two sets of spiral scrapers of the second scraper 411 that contact the feed barrel 408 are made of elastic material. The guide assembly of the feeding mechanism 4 includes a guide cover 414 fixedly mounted on one side of the second scraper 411. The outer shell of the guide cover 414 is conical and is used to guide the powder blown by the air outlet pipe 302 to fall to the inner wall of the return pipe 308. The side of the guide cover 414 close to the air outlet pipe 302 is fixedly mounted with an elastic diaphragm 415. The elastic diaphragm 415 and the guide cover 414 together form a closed cavity. The elastic diaphragm A vibration block 416 is fixedly connected to one side of 415, which is used to vibrate the elastic diaphragm 415 and clean the powdered material on the surface of the elastic diaphragm 415 and the deflector 414. The vibration block 416 is electrically connected to the vibrator 417. A second sealing side plate 418 is fixedly installed on the side of the deflector 414 away from the elastic diaphragm 415 to prevent powder from entering the interior of the vibrator 417. The two sets of spiral scrapers of the second scraper 411 are made of flexible rubber material, and their outer edges form an elastic contact seal with the inner wall of the feed barrel 408. The edges of the elastic scrapers ensure a close fit with the inner wall of the feed barrel 408, effectively removing residual material. The conical deflector 414 guides the powder to flow accurately to the return pipe 308. The elastic diaphragm 415 cooperates with the vibration block 416 to periodically clean the powder adhering to the surface. The second sealing side plate 418 prevents powder from contaminating the vibrator 417, ensuring the long-term stable operation of the equipment.

[0052] Example: Material transportation in flour processing plant production line:

[0053] In the automated production line of a flour mill, the powdered food conveyor is used to transport flour from the storage tank to the mixing equipment. The specific usage process is as follows:

[0054] To initialize the equipment and prepare for feeding, the operator first secures the conveyor drum body 101 to the production line bracket via the base 103, ensuring a tight seal between the first sealing side plate 104 and the conveyor drum body 101. Flour is then poured into the transfer chamber housing 201 via the feed hopper 202. The funnel-shaped structure of the feed hopper 202 ensures smooth flow of flour into the transfer chamber housing 201. At this point, the first servo motor 306 of the wind circulation mechanism 3 is not yet activated, and the second servo motor 402 of the feed mechanism 4 is in standby mode.

[0055] When the control switch is pressed, the first servo motor 306 begins to drive the impeller in the impeller chamber 305 at high speed. The suction force generated by the impeller's rotation draws air from the conveyor drum body 101 through the return pipe 308. The air then enters the air inlet housing 307 through the return pipe 308, passes through the worm gear 304, and enters the impeller chamber 305. Finally, the air is discharged from the impeller chamber 305 into the air outlet housing 303, and then blown through the air outlet pipe 302 toward the transfer chamber housing 201. This high-speed airflow lifts the flour in the transfer chamber housing 201 and, through the connection between the feed assembly 2 and the conveyor drum assembly 1, carries the flour into the conveyor drum body 101 along with the airflow.

[0056] The feeding mechanism operates synchronously with material transfer. The second servo motor 402 is activated, and the driving gear 403 at its output engages and drives the driven gear 404. The first bevel gear 405 at the bottom of the driven gear 404 simultaneously drives the second and third bevel gears 406, 407 on either side. The second bevel gear 406 drives the second scraper bar 411 counterclockwise, while the third bevel gear 407 drives the feed drum 408 clockwise. The first scraper bar 410 on the outer wall of the feed drum 408 rotates with the drum, pushing the flour from the bottom of the conveyor drum 101 forward. The second scraper bar 411 on the inner wall of the feed drum 408, using two sets of spiral scrapers, continuously scrapes away flour adhering to the drum wall, preventing any residual material.

[0057] During the conveying process, the wind circulation system operates continuously, with airflow from the outlet pipe 302 continuously blowing the flour inside the transfer chamber housing 201 into the conveying drum body 101. The return pipe 308 maintains air circulation within the drum, preventing dust accumulation. When the flour reaches the end of the conveying drum body 101, it is discharged through the discharge pipe 102 into the mixing and stirring equipment below, completing the material conveying.

[0058] During equipment shutdown and maintenance, after production is complete, the second servo motor 402 is turned off. After the feed barrel 408 and the second scraper 411 stop rotating, the first servo motor 306 is turned off. At this point, the vibrator 417 of the diversion assembly automatically starts, driving the vibration block 416 to vibrate the elastic diaphragm 415, cleaning any residual flour from the surfaces of the diversion cover 414 and the elastic diaphragm 415. The second sealing side plate 418 effectively prevents powder from entering the vibrator 417, ensuring the cleanliness of the equipment.

[0059] The implementation principle of a powdered food conveying device of the present invention is as follows:

[0060] First, powdered material is fed into the transfer chamber housing 201 through the feed hopper 202. The first servo motor 306 drives the impeller in the impeller chamber 305 to rotate, and the generated airflow is blown into the transfer chamber housing 201 through the air outlet pipe 302. The high-speed airflow blows the powder in the transfer chamber up, is guided by the guide component, and enters the interior of the conveying cylinder body 101 through the guide hole 409, completing the initial feeding and establishing the wind conveying power.

[0061] Secondly, the second servo motor 402 drives the third bevel gear 407 and the second bevel gear 406 through the meshing transmission of the driving gear 403, the driven gear 404 and the first bevel gear 405, so that the feeding barrel 408 rotates clockwise and the second scraper 411 rotates counterclockwise. The first scraper 410 on the outer wall of the feeding barrel 408 rotates with the barrel body, pushing the powder forward along the inner wall of the conveying barrel body 101; the spiral flexible scraper elastic material of the second scraper 411 is tightly attached to the inner wall of the feeding barrel 408, and scrapes off the residual powder on the inner wall when rotating in the opposite direction to avoid material accumulation.

[0062] Next, the conical air guide hood 414 guides the powder blown by the air outlet duct 302 to fall accurately onto the inner wall of the return pipe 308, ensuring that the material enters the conveying cylinder along the predetermined path. The cleaning structure composed of the elastic diaphragm 415 and the vibration block 416 vibrates periodically under the drive of the vibrator 417 to remove the powder attached to the surface of the air guide hood 414 and the elastic diaphragm 415 to prevent blockage; the second sealing side plate 418 isolates the vibrator 417 from the powder to ensure the safety of the components.

[0063] Next, the impeller chamber 305 is connected to the air outlet chamber housing 303 through the worm gear tube 304, and the return pipe 308 draws the air in the conveying cylinder body 101 back to the air inlet chamber housing 307, forming an internal air circulation of "transfer chamber housing 201 → conveying cylinder → impeller chamber 305". This process maintains the internal air pressure of the system stable, avoids dust overflow, and at the same time continuously provides blowing power for the air outlet pipe 302 to ensure the continuity of wind transportation.

[0064] Finally, the powder is pushed by the feeding cylinder 408 and the first scraper 410, and moves along the conveying cylinder body 101 to the discharge pipe 102, and is finally transported through the discharge pipe 102. During the whole process, the gear transmission assembly drives the feeding and cleaning simultaneously, the guide assembly optimizes the powder flow direction, and the wind circulation mechanism 3 provides power and maintains air pressure balance. The various components work together to achieve efficient and clean transportation of powdered food. At the same time, the elastic sealing and vibration cleaning design can reduce residue and improve equipment reliability.
