[0002] Feeding equipment is generally used for the feeding support of material processing, providing continuous feeding for the processing of the device to ensure the continuous and stable processing of the device.

[0003] When fine powder materials are fed during processing, due to their small volume, their weight will be greater under the same volume, resulting in greater pressure on the feeding device. However, the existing feeding equipment only transports materials through a single feeding pipeline, causing the pipeline to bear excessive pressure and easily resulting in pipeline rupture and damage, affecting the safety and stability during the use of the device.

[0004] Therefore, we provide a fine powder material pressure-reducing feeding device. Content of the Utility Model

[0027] Embodiment 1: A pressure-reducing feeding device for fine powder materials, as Figure 1 - Figure 4 shown, includes a first feeding mechanism and a second feeding mechanism.

[0028] The first feeding mechanism includes a first feeding cylinder 1, a flow cone 2, a shunt plate 3, and a shunt cylinder 4. The first feeding cylinder 1 is installed above the flow cone 2, the shunt plate 3 is installed inside the flow cone 2, the shunt cylinder 4 is installed below the flow cone 2. There are at least two shunt plates 3, and the connection part of the two shunt plates 3 is located directly below the first feeding cylinder 1, and each of the two shunt plates 3 guides a shunt cylinder 4, and the two shunt cylinders 4 are evenly distributed at the lower end of the flow cone 2.

[0029] The second feeding mechanism includes a second feeding cylinder 13, a connecting cylinder 14, a flow pipe 15, and a diversion pipe 16. The flow pipe 15 is installed outside the second feeding cylinder 13, the connecting cylinder 14 is installed between the flow pipe 15 and the diversion pipe 16, and both the flow pipe 15 and the diversion pipe 16 are inserted into the connecting cylinder 14.

[0030] Among them, there are at least two second feed cylinders 13, and both of the two second feed cylinders 13 are installed at the upper end of the flow cone 2. One end of the diversion pipe 16 away from the connection cylinder 14 is installed outside the shunt cylinder 4.

[0031] Under the shunt support of the shunt plate 3, the fine powder material flowing into the interior of the flow cone 2 through the first feed cylinder 1 is evenly divided into two parts and flows into the interiors of the two shunt cylinders 4 respectively. Then, under the guiding flow of the two shunt cylinders 4, the fine powder material flowing through the middle is separated and flowed, so as to relieve the situation of excessive simultaneous flow pressure. At the same time, a small amount of fine powder material is added to the interiors of the two second feed cylinders 13, and under the guiding of the flow pipe 15 and the diversion pipe 16, it directly flows into the interior of the shunt cylinder 4. And under the connection and sealing of the connection cylinder 14, the specifications of the flow pipe 15 and the diversion pipe 16 can be replaced to adjust the flow rate of the material inside. Under the simultaneous feeding support of the two second feed cylinders 13, the materials flow into the interior of the shunt cylinder 4 respectively, so that while the materials are separated and flowed to relieve the flow pressure, the flow feeding speed is ensured. Thus, under the combined use of the first feeding mechanism and the second feeding mechanism, the device can be dispersed from one feeding part into three feeding parts, and the same material is flowed through three times of separation, which can relieve the pressure of each flow part, reduce the flow time of each part, and improve the flow efficiency.

[0032] As Figure 1 - Figure 4 shown, the first feed cylinder 1 is located between the two second feed cylinders 13, and there are at least two flow pipes 15, diversion pipes 16, and connection cylinders 14.

[0033] The first feed cylinder 1 is internally connected to the flow cone 2, and the flow cone 2 is internally connected to the shunt cylinder 4.

[0034] The second feed cylinder 13, the flow pipe 15, the diversion pipe 16, the connection cylinder 14, and the shunt cylinder 4 are internally connected.

[0035] Under the feeding support of the two second feed cylinders 13 and one first feed cylinder 1, and setting their positions on the same side, it is convenient to feed separately. At the same time, under the support of the corresponding flow part, the stability and reliability of the device's feeding are ensured, and the stability of the device's feeding pressure reduction is improved.

[0036] Embodiment 2: A fine powder material pressure-reducing feeding device, as Figure 1 - Figure 4 shown, a flow vertical pipe 5 is arranged below the shunt cylinder 4. The flow vertical pipe 5 is simultaneously connected to the two shunt cylinders 4, and a stirring mechanism is arranged inside the shunt cylinder 4.

[0037] Under the guiding and assisting of the flow vertical pipe 5, the stability of the material flow direction is ensured, and the safety and accuracy of the overall operation of the device are improved.

[0038] As Figure 1 - Figure 4 shown in the figure, the stirring mechanism includes a rotating rod 6, a stirring rod 7, and a rotating motor 8. The rotating rod 6 is installed at the output end of the rotating motor 8, the stirring rod 7 is installed outside the rotating rod 6, the rotating motor 8 is installed outside the vertical flow pipe 5, the rotating rod 6 and the stirring rod 7 are rotatably installed inside the vertical flow pipe 5, and a rotating rod 6 and a stirring rod 7 are provided below each shunt cylinder 4.

[0039] The stirring mechanism further includes a transmission rod 9, a spiral feeder 10, a driving motor 11, and a flow cylinder 12. The transmission rod 9 is installed at the output end of the driving motor 11, the driving motor 11 is installed outside the transmission rod 9, and the transmission rod 9 is located at the junction of the flow cylinder 12 and the vertical flow pipe 5.

[0040] When the material flows into the vertical flow pipe 5, first start the rotating motor 8 to drive the rotating rod 6 and the stirring rod 7 to rotate inside the vertical flow pipe 5, stir the flowing and accumulated materials, improve the refinement degree of the materials, and at the same time ensure the rapidity when it continues to flow downward. Then start the driving motor 11 to drive the transmission rod 9 and the spiral feeder 10 to rotate synchronously. Under the spiral feeding of the spiral feeder 10, the agitated materials are moved to the next processing step, and under the spiral feeding of the spiral feeder 10, the material flow space can be limited, and the materials flow downward stably and slowly, ensuring the sufficiency of the stirring of the rotating rod 6 and the stirring rod 7, thereby preventing the situation that the materials themselves continuously accumulate and generate excessive pressure, and improving the pressure reduction effect when the device feeds materials.

[0041] Working principle: First, add materials into the first feeding cylinder 1 and the two second feeding cylinders 13 at the same time, so that the fine powder materials flowing into the flow cone 2 through the first feeding cylinder 1 are evenly divided into two parts and flow into the two shunt cylinders 4 respectively. Under the guiding flow of the two shunt cylinders 4, the fine powder materials flowing through the middle are distinguished and flowed, so as to relieve the situation of excessive simultaneous flow pressure. The materials flowing through the second feeding cylinder 13 flow directly into the shunt cylinder 4 under the guiding of the flow pipe 15 and the guiding pipe 16, further dispersing and relieving the pressure generated when the materials flow. At the same time, under the stirring of the rotating rod 6 and the stirring rod 7, and the spiral limiting feeding of the spiral feeder 10, the situation that the materials themselves continuously accumulate and generate excessive pressure is prevented, and the pressure reduction effect when the device feeds materials is improved.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
