Anti-sticking and self-cleaning powder particle conveying system

Abstract

A self-cleaning, anti-sticking powder conveying system belongs to the field of powder conveying technology. It includes a receiving hopper with a negative pressure fan at its top. A material passage pipe is installed inside one port of the negative pressure fan, and several guiding mechanisms are installed inside the material passage pipe. A cleaning mechanism is installed on the surface of each guiding mechanism. Through the arrangement of the guiding mechanism, cleaning mechanism, and material passage pipe, powder particles adhering to the inner wall of the pipe can be effectively blown off. Simultaneously, the system automatically removes accumulated dust during operation. Utilizing the interaction between airflow and particle movement, powder particles adhering to the inner wall of the pipe are blown off, and a certain degree of vibration is applied to the inside of the pipe, carrying the particles away with the airflow. This reduces the adhesion rate of powder during conveying, ensuring smooth and stable conveying, thereby improving production efficiency and reducing maintenance costs. The introduction of micro-vibration breaks down powder adhesion forces, reducing blockage.

[0001] This invention relates to the field of powder and particle conveying technology, specifically to an anti-sticking and self-cleaning powder and particle conveying system. Background Technology

[0002] Powder conveying refers to the process of transporting solid particles or powders from one place to another using specific technologies and equipment. This process is very important in industrial production because it involves the manufacturing and processing of many products. It is mainly used to transport bulk, dry powder particles or powders from one location to another through specific equipment and pipelines, especially in industries such as chemical, pharmaceutical, and food, where the requirements for the accuracy and cleanliness of powder conveying are even higher.

[0003] However, in existing systems, when conveying powder particles, the powder particles inside the conveying pipes become damp, causing problems such as adhesion and blockage, and the inside of the pipe walls is difficult to clean. Summary of the Invention

[0004] The purpose of this invention is to provide a non-stick, self-cleaning powder particle conveying system, which solves the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a non-sticking self-cleaning powder particle conveying system, comprising a receiving hopper, a negative pressure fan at the top of the receiving hopper, a material passage pipe inside one port of the negative pressure fan, a plurality of guiding mechanisms inside the material passage pipe, a cleaning mechanism installed on the surface of the guiding mechanism, and a mixing mechanism at the top of the receiving hopper near the negative pressure fan.

[0006] Furthermore, the guiding mechanism includes a guide rail disposed inside the feed tube, the surface of the guide rail is provided with a guide groove, the inside of the guide groove is provided with a toothed groove, one end of the guide rail is provided with a mounting hole, the other end of the guide rail is fixedly connected with a connecting block, and the surface of the guide rail near the guide groove is also provided with a sliding groove.

[0007] Furthermore, the cleaning mechanism includes a rotating roller installed inside a sliding groove on the surface of the guide rail. An L-shaped rod is rotatably connected inside the rotating roller, and an arrangement ring is fixedly connected to the end of the L-shaped rod. The surface of the arrangement ring has several circular arc openings, and a peeling component is rotatably connected through the surface of the circular arc openings. One of the peeling components has a hollow sleeve tooth on its surface. A first drive motor is fixedly connected to the side of the arrangement ring surface near the hollow sleeve tooth. A first rotating gear is fixedly connected to the output end of the first drive motor. A second rotating tooth is provided on the inner ring of the arrangement ring near the first rotating gear. The surface of the second rotating tooth meshes with the hollow sleeve tooth and the first rotating gear. The surface of the first rotating gear near the rotating roller meshes with the tooth groove inside the guide groove.

[0008] Furthermore, a connecting short rod is rotatably connected to the surface of the peeling assembly, a C-shaped rod is rotatably connected to the surface of the connecting short rod, a limiting rod is rotatably connected to the inside of the C-shaped rod, a peeling block is rotatably connected to the end of the limiting rod, a baffle is fixedly connected to the inside of the peeling block, a shovel plate is fixedly connected to one side of the peeling block, and several conical holes are opened on the other side of the peeling block.

[0009] Furthermore, the mixing mechanism includes a second drive motor disposed at the top of the receiving hopper, and a sinking rod is fixedly connected to the output end of the second drive motor.

Through the arrangement of a guiding mechanism, a cleaning mechanism, and a feed pipe, powder particles adhering to the inner wall of the pipe can be effectively blown off. Simultaneously, the system automatically removes accumulated dust during operation. Utilizing the interaction between airflow and particle movement, powder particles adhering to the inner wall of the pipe are blown off, creating a certain degree of vibration within the pipe, and are carried away by the airflow. This reduces the adhesion rate of powder during conveying, ensuring smooth and stable conveying, thereby improving production efficiency and reducing maintenance costs. Furthermore, by introducing micro-vibration, the adhesive force of the powder is broken, reducing blockage.

[0029] 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.

[0030] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0031] Combination Figures 1-11 A non-stick, self-cleaning powder particle conveying system includes a receiving hopper 1, a negative pressure fan 2 at the top of the receiving hopper 1, a material passage pipe 3 inside one of the ports of the negative pressure fan 2, a number of guide mechanisms 4 inside the material passage pipe 3, a cleaning mechanism 5 installed on the surface of the guide mechanism 4, and a mixing mechanism 6 at the top of the receiving hopper 1 near the negative pressure fan 2.

[0032] The feed pipe 3 is designed with left and right splicing, which facilitates the disassembly of the inside of the feed pipe 3. The left and right directions are fixed by bolts. In order to facilitate the installation of the guide mechanism 4 and the cleaning mechanism 5 inside the feed pipe 3, one port of the negative pressure fan 2 on the receiving hopper 1 is connected to the feed pipe 3, and the other port of the feed pipe 3 is connected to the internal cavity of the receiving hopper 1, which facilitates the conveying of powder particles inside the feed pipe 3.

[0033] Please see Figures 1-6The guiding mechanism 4 includes a guide rail 41 disposed inside the feed pipe 3. The surface of the guide rail 41 is provided with a guide groove 42. The inside of the guide groove 42 is provided with a toothed groove. One end of the guide rail 41 is provided with a mounting hole. The other end of the guide rail 41 is fixedly connected to a connecting block 43. The surface of the guide rail 41 near the guide groove 42 is also provided with a sliding groove.

[0034] One end of the guide mechanism 4 is provided with a mounting hole. When in use, it is used to connect the other end of the guide rail 41 with the connecting block 43. The curvature of the guide mechanism 4 can be adjusted according to the actual use, but it must be ensured that the cleaning mechanism 5 moves in a spiral direction inside the feed tube 3.

[0035] The cleaning mechanism 5 includes a rotating roller 51 installed inside a sliding groove on the surface of the guide rail 41. An L-shaped rod 52 is rotatably connected inside the rotating roller 51. An arrangement ring 53 is fixedly connected to the end of the L-shaped rod 52. The surface of the arrangement ring 53 has several circular arc openings. A peeling component 54 is rotatably connected through the surface of the circular arc openings. One of the peeling components 54 has a hollow sleeve tooth 55 on its surface. A first drive motor 56 is fixedly connected to the side of the arrangement ring 53 near the hollow sleeve tooth 55. A first rotating gear 57 is fixedly connected to the output end of the first drive motor 56. A second rotating tooth 58 is provided on the inner ring of the arrangement ring 53 near the first rotating gear 57. The surface of the second rotating tooth 58 meshes with the hollow sleeve tooth 55 and the first rotating gear 57. The surface of the first rotating gear 57 near the rotating roller 51 meshes with the tooth groove inside the guide groove 42.

[0036] The rotating roller 51 on the cleaning mechanism 5 slides and rolls within the sliding groove on one side of the guide rail 41 on the guide mechanism 4 during operation. The first rotating gear 57 on the cleaning mechanism 5 always runs within the guide slot 42 on the guide rail 41 of the guide mechanism 4 and meshes with the tooth groove inside the guide slot 42. When the cleaning mechanism 5 is operating, the output end of the first drive motor 56 drives the first rotating gear 57 to work. At this time, the rotation of the first rotating gear 57 drives the second rotating gear 58 to rotate. When the second rotating gear 58 moves, it drives the hollow sleeve tooth 55 on one of the peeling components 54 to operate, causing the hollow sleeve tooth 55 to drive the peeling component 54 to rotate. The arrangement ring... The entire ring 53 is in an arc shape, and the part of the ring 53 that contacts the peeling component 54 and the interior of the peeling component 54 are both circular. The peeling component 54 is larger than the circular part of the ring 53, allowing the peeling component 54 to rotate. The part that does not contact the inner circular part of the peeling component 54 is O-shaped and larger than the inner circular part of the peeling component 54. This setting is to limit its movement and prevent unnecessary offset of the peeling component 54 during movement, which could lead to mechanical failure. When the second rotating tooth 58 works, it drives the hollow sleeve tooth 55 to rotate the peeling component 54. The rotation of the outer ring of the peeling component 54 will drive the C-shaped rod 542 to make a circular motion around the axis of the inner ring of the peeling component 54. The connecting short rod 541 will move when the C-shaped rod 542 moves. The range of motion of the C-shaped rod 542 is limited to prevent it from exceeding its operating trajectory. When the C-shaped rod 542 rotates, the peeling block 544 connected to it via the limiting rod 543 also performs a circular motion. The peeling block 544 rotates in a spiral trajectory inside the feed pipe 3 through the guide mechanism 4, scraping off the dust and large particles attached to it. The airflow inside the feed pipe 3, originating from the port furthest from the receiving hopper 1, is driven by the suction generated by the negative pressure fan 2 to transport the powder particles into the chamber of the receiving hopper 1. When the opening of the peeling block 544 faces away from the suction direction of the negative pressure fan 2, the scraped large particles and relatively moist dust are stored. Inside the opening of the peeling block 544, when the opening of the peeling block 544 faces the receiving hopper 1, it is sucked out by the suction generated by the negative pressure fan 2 and then sent into the cavity of the receiving hopper 1. When the peeling block 544 comes into contact with the cavity of the feed pipe 3, if the foreign matter present cannot be removed by hitting the inner wall of the pipe or scraping, the powder particles present inside the feed pipe 3 are scraped off by the inclined surface of the scraper plate 546. When the opening of the peeling block 544 faces away from the negative pressure fan 2, the inclined surface of the scraper plate 546 will be sent into the cavity of the peeling block 544 by the wind force through the inclined surface of the baffle 545. When the opening of the peeling block 544 faces the negative pressure fan 2, if its moisture or stickiness is too high, it will adhere to the right angle surface on the other side of the baffle 545.At this point, the debris remains inside the peeling block 544. When the entire device has finished transporting the powder particles, the cleaning mechanism 5 moves to the port of the feed pipe 3 furthest from the receiving hopper 1. At this time, the staff removes the debris from inside the peeling block 544. The peeling block 544, baffle 545, and scraper 546 on the cleaning mechanism 5 are all made of flexible material to prevent damage to the inner wall of the feed pipe 3 when they tap and scrape it inside the feed pipe 3, thus shortening its service life. The operating range of its first drive motor 56 is such that after moving from the inner edge of the feed pipe 3 port furthest from the receiving hopper 1 to the feed pipe 3 port near the negative pressure fan 2, its output end reverses and circulates inside the feed pipe 3.

[0037] The surface of the peeling assembly 54 is rotatably connected to a connecting short rod 541, the surface of the connecting short rod 541 is rotatably connected to a C-shaped rod 542, the inside of the C-shaped rod 542 is rotatably connected to a limiting rod 543, the end of the limiting rod 543 is rotatably connected to a peeling block 544, the inside of the peeling block 544 is fixedly connected to a baffle 545, one side of the peeling block 544 is fixedly connected to a shovel plate 546, and the other side of the peeling block 544 has several conical holes.

[0038] There are two C-shaped rods 542, which are connected to the surface of another peeling component 54 by connecting short rods 541. The peeling block 544 has several conical holes, with the holes on the side closer to the baffle 545 being smaller and the holes on the side farther from the baffle 545 being larger. This allows the airflow inside the baffle 545 to be increased when the opening of the peeling block 544 is close to the negative pressure fan 2, so that the objects inside the peeling block 544 can be sucked away by the wind. In addition, the opening on the side of the peeling block 544 closer to the shovel 546 is also smaller than the opening away from the shovel 546.

[0039] The mixing mechanism 6 includes a second drive motor 61 located at the top of the receiving hopper 1. The output end of the second drive motor 61 is fixedly connected to a sinking rod 62. Two sets of stirring rods 63 are arranged in a circumferential array on the surface of the sinking rod 62. A lever 64 is also provided on the side of the sinking rod 62 near the stirring rods 63.

[0040] In the process of using the device, when the powder particles inside the feed pipe 3 are conveyed to the inside of the receiving hopper 1, the second drive motor 61 on the mixing mechanism 6 starts to move. When the second drive motor 61 moves, it will drive the sinking rod 62 to rotate the lever 64 and the stirring rod 63. The length of the lever 64 is greater than the length of the stirring rod 63 in the middle, and the length of the stirring rod 63 in the middle is greater than the length of the stirring rod 63 below the second drive motor 61. Because the inner cavity of the receiving hopper 1 is a conical cavity that is larger at the top and smaller at the bottom, this is more conducive to the uniform mixing of the powder particles inside the receiving hopper 1 and facilitates the feeding.

[0041] Please see Figures 1-11 The surface of the feed tube 3 is provided with a plurality of L-mount plates 7, and the surface of the L-mount plates 7 is provided with mounting holes.

[0042] In actual use of the device, if the length of the feed pipe 3 is actually too long, resulting in a large weight and deformation, then the L-mount plate 7 is installed on the surface of the feed pipe 3, and the mounting holes of the L-mount plate 7 are bolted to the wall or a suitable location to stabilize the feed pipe 3.

[0043] Several connecting plates 8 are fixedly connected to the surface of the receiving bucket 1.

[0044] The connecting plate 8 is designed to fix the receiving bucket 1 and prevent the device from shaking. The extension rod 9 and the stabilizing leg 10 connected to the receiving bucket 1 by the connecting plate 8 are used to raise the height of the receiving bucket 1, so that the discharge pipe 11 can be installed. While raising the height of the receiving bucket 1, the extension rod 9 and the stabilizing leg 10 also facilitate the workers to promptly pack and load the powder particles sent from inside the receiving bucket 1 into the discharge pipe 11.

[0045] The bottom of the connecting plate 8 is threadedly connected to an extension rod 9, and the bottom of the extension rod 9 is fixedly connected to a stabilizing leg 10.

[0046] The bottom end of the receiving hopper 1 is fixedly connected to the discharge pipe 11, and a collar is fixedly installed at the edge of the other end of the discharge pipe 11. Specific Implementation

[0048] First, the device is fixedly installed in a suitable position. If necessary, such as when the feed pipe 3 is too long, the feed pipe 3 is limited and fixed by several L-shaped mounting plates 7 set on the surface of the feed pipe 3. Then, the powder or granules are fed into the port of the feed pipe 3 away from the receiving hopper 1. The external power supply starts the second drive motor 61 on the mixing mechanism 6 to transport the powder or granules into the feed pipe 3. The cleaning mechanism 5 starts to operate on the guide mechanism 4. The output end of the first drive motor 56 drives the first rotating gear 57 to work. At this time, the rotation of the first rotating gear 57 drives the second rotating gear 58 to rotate, so that the hollow sleeve gear 55 drives the peeling component 54 to rotate. When the second rotating gear 58 works, it drives the hollow sleeve gear 55 to make the peeling component 54 enter the... During operation, the outer ring of the peeling component 54 rotates, causing the C-shaped rod 542 to move in a circular motion around the peeling component 54. When the C-shaped rod 542 rotates, the peeling block 544 connected to it via the limiting rod 543 also moves in a circular motion. The peeling block 544 rotates in a spiral trajectory inside the chamber of the feed pipe 3, guided by the guide mechanism 4. The airflow inside the feed pipe 3 is driven by the suction generated by the negative pressure fan 2, which transports the powder particles. The suction generated by the negative pressure fan 2 draws them out and sends them into the chamber of the receiving hopper 1. At this time, the cleaning mechanism 5 scrapes and peels off the dust and large particles attached to the chamber of the feed pipe 3. When the opening of the peeling block 544 faces away from the negative pressure fan 2... When the object is inside the peeling block 544, the angled surface of the shovel plate 546 will be sent into the cavity of the peeling block 544 by the wind force through the angled surface of the baffle 545. When the opening of the peeling block 544 is facing the negative pressure fan 2, if the moisture or stickiness is too high, it will adhere to the right angled surface of the baffle 545 and remain inside the peeling block 544. The several conical holes on the peeling block 544 are smaller on the side closer to the baffle 545 and larger on the side farther from the baffle 545. This allows the airflow inside the baffle 545 to be increased when the opening of the peeling block 544 is close to the negative pressure fan 2, so that the object inside the peeling block 544 can be sucked away by the wind force. The cleaning mechanism 5 starts to move back and forth on the guide mechanism 4 when the whole device is working. In the reciprocating motion, when the powder or granules are conveyed into the receiving hopper 1, the second drive motor 61 drives the sinking rod 62 to rotate the lever 64 and the stirring rod 63, so that the powder or granules are mixed or dispersed inside the conical cavity of the receiving hopper 1. When the inside of the receiving hopper 1 reaches a certain volume or the mixing is completed, the discharge pipe 11 is opened, and a burlap sack is placed around the collar on the discharge pipe 11 to package and distribute the finished product. Alternatively, the collar on the discharge pipe 11 can be removed, and other devices can be connected to the discharge pipe 11 to introduce it into the next processing flow. When the height of the receiving hopper 1 is low, the extension rod 9 and the stabilizing leg 10 connected to the connecting plate 8 can be extended to raise the height of the receiving hopper 1, thereby ensuring normal discharge.
