Abstract
Description
Technical Field
[0001] This application relates to the field of material feeding technology, and more specifically, to a pneumatic conveying material feeding device. Background Technology
[0002] A pneumatic conveying system is a device that uses the flow energy of gas to transport materials. It mainly consists of a feeder, conveying pipeline, air source unit, and control system. The feeder evenly delivers material into the conveying pipeline, while the air source unit provides gas with a certain pressure and flow rate, propelling the material along the pipeline to the designated location. The control system monitors and regulates the entire conveying process, ensuring stable and efficient material transport. It is widely used in industries such as chemical, food, and building materials, enabling automated material transport, reducing manual labor intensity, and improving production efficiency.
[0003] In traditional pneumatic conveying systems, damp or sticky materials tend to clump and stick together during transport, leading to pipe blockages and conveying interruptions. Existing systems lack efficient material dispersion and drying mechanisms, relying on manual unblocking or frequent shutdowns for cleaning, resulting in high labor intensity and low production efficiency.
[0004] In view of this, this application proposes a pneumatic conveying and feeding device. Utility Model Content
[0005] The purpose of this application is to provide a pneumatic conveying and feeding device that solves the technical problems in the background art and achieves the technical effect of a pneumatic conveying and feeding device.
[0006] This application provides a pneumatic conveying and feeding device, including a feeding pipe, a fan at one end of the feeding pipe, a feed pipe fixedly connected to the upper part of the outer wall of one end of the feeding pipe, a dispersing mechanism provided at the upper part of the inside of the feed pipe, and a filter plate fixedly connected inside the feed pipe; the dispersing mechanism includes a sealed box located at the upper part of the inside of the feed pipe, a first bevel gear rotatably connected to one side of the inside of the sealed box, a second bevel gear rotatably connected to the upper part of the inside of the sealed box, a third bevel gear rotatably connected to the lower part of the inside of the sealed box, a rotating cylinder fixedly connected to the lower end of the third bevel gear, and the rotating cylinder extending out of the sealed box, multiple second heating rods fixedly connected to both sides of the outer wall of the rotating cylinder, an extension rod fixedly connected to the lower end of the second bevel gear, and the extension rod sequentially passes through the third bevel gear and the rotating cylinder, a rotating frame fixedly connected to the lower end of the extension rod, and multiple first heating rods fixedly connected to both sides of the inner wall of the rotating frame.
[0007] Optionally, an air inlet pipe is fixedly inserted into the outer wall of one end of the blower, and an air outlet pipe is fixedly inserted into one end of the blower, with the other end of the air outlet pipe sleeved onto one end of the feeding pipe.
[0008] Optionally, a rotating rod is fixedly connected inside the feed pipe, and one end of the rotating rod extends out of the feed pipe. Multiple material distribution plates are fixedly connected to the outer wall of the rotating rod.
[0009] Optionally, one end of the first bevel gear is fixedly connected to a drive shaft, and the drive shaft passes through one side of the sealing box and one side of the feed pipe in sequence. One end of the drive shaft and the rotating rod are both fixedly connected to a drive wheel, and a drive belt is connected between the two drive wheels.
[0010] Optionally, a fixing frame is fixedly connected to the upper part of the outer wall of the feed pipe, and a motor is fixedly connected to the front end of the fixing frame, and the output end of the motor is fixedly connected to the transmission wheel.
[0011] Optionally, support rods are fixedly connected to all four sides of the lower end face of the sealing box, and one end of the support rod is fixedly connected to the inner wall of the feed pipe.
[0012] Optionally, the first bevel gear meshes with the second bevel gear and the third bevel gear respectively, and the first heating rod and the second heating rod are staggered.
[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:
[0014] 1. This application utilizes a drive shaft to drive a first bevel gear within a sealed box, which in turn drives a second and third bevel gear to rotate in opposite directions. The second bevel gear drives a rotating frame and a first heating rod on an extension rod, while the third bevel gear drives a rotating cylinder and a second heating rod, forming an alternating, counter-rotating heating rod assembly. This design effectively breaks down adhered materials through the combined effects of mechanical shearing force and heat, while simultaneously evaporating moisture to prevent the materials from re-agglomerating due to dampness. Large, incompletely broken-down pieces of material are intercepted by the filter screen, preventing them from entering the feed pipe and causing blockages. The filter screen and the heating rod assembly work together to ensure that only dry, dispersed materials pass through, significantly improving the reliability of the conveying system.
[0015] 2. This application utilizes a rotating rod to drive the distribution plate to rotate. The distribution plate, on one hand, evenly conveys the material to the feeding pipe through rotation; on the other hand, it forms a mechanical barrier, preventing strong airflow generated by the fan from entering the feeding pipe. This effectively avoids airflow interference with material descent, ensures a stable feeding rate, and prevents material accumulation or splashing due to air pressure fluctuations.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.
[0021] Reference Figures 1-3 This application provides a pneumatic conveying and feeding device, including a feeding pipe 1, a fan 2 at one end of the feeding pipe 1, and a feed pipe 5 fixedly connected to the upper part of the outer wall of one end of the feeding pipe 1. A dispersing mechanism 8 is provided above the inside of the feed pipe 5, and a filter plate 9 is fixedly connected inside the feed pipe 5. The dispersing mechanism 8 includes a sealing box 801 located above the inside of the feed pipe 5. A first bevel gear 804 is rotatably connected to one side of the inside of the sealing box 801, a second bevel gear 805 is rotatably connected to the upper part of the inside of the sealing box 801, and a third bevel gear 806 is rotatably connected to the lower part of the inside of the sealing box 801. A rotating cylinder 807 is fixedly connected to the lower end of the third bevel gear 806. A sealing box 801 extends from 807. Multiple second heating rods 811 are fixedly connected to both sides of the outer wall of the rotating cylinder 807. An extension rod 810 is fixedly connected to the lower end of the second bevel gear 805, and the extension rod 810 passes through the third bevel gear 806 and the rotating cylinder 807 in sequence. A rotating frame 808 is fixedly connected to the lower end of the extension rod 810. Multiple first heating rods 809 are fixedly connected to both sides of the inner wall of the rotating frame 808. The first bevel gear 804 meshes with the second bevel gear 805 and the third bevel gear 806 respectively. The first heating rods 809 and the second heating rods 811 are staggered. The rotation of the first bevel gear 804 drives the second bevel gear 805 and the third bevel gear 806 to rotate in opposite directions.
[0022] The second bevel gear 805 drives the rotating frame 808 on the extension rod 810 and the first heating rod 809, while the third bevel gear 806 drives the rotating cylinder 807 and the second heating rod 811, forming an alternating, counter-rotating heating rod assembly. This design effectively breaks up adhered materials through the combined action of mechanical shearing force and heat, while simultaneously evaporating moisture to prevent the materials from re-agglomerating due to dampness. Large pieces of material that are not completely broken up are intercepted by the filter plate 9, preventing them from entering the feed pipe 1 and causing blockages. The filter plate 9 works in conjunction with the heating rod assembly to ensure that only dry, dispersed materials pass through, significantly improving the reliability of the conveying system.
[0023] An air inlet pipe 3 is fixedly inserted into the outer wall of one end of the blower 2, and an air outlet pipe 4 is fixedly inserted into the other end of the blower 2. The other end of the air outlet pipe 4 is sleeved onto one end of the feeding pipe 1. A rotating rod 10 is fixedly connected inside the feeding pipe 5, and one end of the rotating rod 10 extends out of the feeding pipe 5. Multiple distribution plates 11 are fixedly connected to the outer wall of the rotating rod 10. The rotation of the rotating rod 10 drives the distribution plates 11 to rotate. The distribution plates 11, on the one hand, evenly convey the material to the feeding pipe 1 through rotation, and on the other hand, form a mechanical barrier to prevent the strong airflow generated by the blower 2 from flowing back into the feeding pipe 5. This effectively avoids airflow interference with the material falling, ensures a stable feeding rate, and prevents material accumulation or splashing caused by air pressure fluctuations.
[0024] One end of the first bevel gear 804 is fixedly connected to a drive shaft 803, which passes through one side of the sealing box 801 and one side of the feed pipe 5. One end of the drive shaft 803 and the rotating rod 10 are both fixedly connected to a drive wheel 12. A drive belt 13 is connected between the two drive wheels 12. A fixed frame 6 is fixedly connected to the upper part of the outer wall of the feed pipe 5. A motor 7 is fixedly connected to the front end of the fixed frame 6, and the output end of the motor 7 is fixedly connected to the drive wheel 12. The motor 7 drives the two drive wheels 12 and the drive belt 13 to rotate synchronously, and at the same time drives the rotating rod 10 and the drive shaft 803 to rotate synchronously, thereby realizing the simultaneous breaking and conveying of materials.
[0025] Support rods 802 are fixedly connected to all four sides of the lower end face of the sealing box 801, and one end of the support rod 802 is fixedly connected to the inner wall of the feed pipe 5, which serves to fix and limit the sealing box 801.
[0026] Working principle: First, the feed pipe 5 is installed at the outlet of the material box. Simultaneously, the blower 2 and motor 7 are started. The blower 2 blows air into the air inlet pipe 3 through the air inlet pipe 3 and then discharges it from the feed pipe 1. The motor 7 drives the output end to rotate. The rotation of the output end drives one transmission wheel 12 to rotate. The rotation of the transmission wheel 12 drives the transmission belt 13 and another transmission wheel 12 to rotate synchronously. The rotation of the two transmission wheels 12 drives the transmission shaft 803 and the rotating rod 10 to rotate synchronously. The rotation of the rotating rod 10 drives multiple material distribution plates 11 to rotate. The material distribution plates 11 serve two purposes: on the one hand, they convey materials into the feed pipe 1, and on the other hand, they prevent strong air from rushing into the top of the feed pipe 5 and affecting the feeding rate.
[0027] The rotation of the drive shaft 803 drives the first bevel gear 804 inside the sealing box 801 to rotate. The rotation of the first bevel gear 804 drives the meshing second bevel gear 805 and third bevel gear 806 to rotate synchronously. At the same time, the second bevel gear 805 and the third bevel gear 806 rotate in opposite directions. The rotation of the second bevel gear 805 drives the extension rod 810 and the rotating frame 808 on the extension rod 810 to rotate synchronously. The rotation of the third bevel gear 806 drives the rotating cylinder 807 and the multiple second heating rods 811 on the rotating cylinder 807 to rotate synchronously. Since the second heating rods 811 and the first heating rods 809 on the rotating frame 808 are staggered, and the rotation direction of the extension rod 810 and the rotating cylinder 807 is opposite, the material enters the upper part of the feed pipe 5. Some of the material will stick together. If the sticky material directly enters the feed pipe 1, it will easily cause the feed pipe 1 to be blocked.
[0028] However, the filter plate 9 will block the sticky materials. The alternating rotation of the first heating rod 809 and the second heating rod 811 will break up the sticky materials and evaporate the excess moisture inside the materials, keeping the materials dry and preventing them from sticking together again after entering the feeding pipe 1. Finally, the broken materials will pass through the filter plate 9 and fall onto the distribution plate 11. The distribution plate 11 will then flip and convey the materials into the feeding pipe 1, where strong winds will transport the materials.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
