Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of material conveying, especially a spiral conveying device of Raymond mill. BACKGROUND

[0002] In the traditional mill conveying system, there are many problems that cannot meet the diversified production needs. On the one hand, for the material with fast discharge rate and particle diameter of 3-5mm, the conventional spiral conveying blade and matching cylinder cannot realize fast and efficient conveying. The conveying blade with single pitch design cannot meet the conveying speed when facing a large amount of such material, which leads to material accumulation at the mill discharge port, seriously affecting the continuity and production efficiency of the grinding operation, and cannot meet the rhythm of large-scale production.

[0003] On the other hand, when dealing with slow discharge rate and fine material, the traditional conveying structure lacks precise control ability. The blade with large pitch is easy to cause the material to slide and block during conveying, which cannot guarantee stable and accurate conveying of the material, reduces the adaptability of the mill to such material, and cannot meet the process requirements of fine material processing. SUMMARY

[0004] The utility model aims at at least one of the technical problems in the related art to some extent.

[0010] A connecting cylinder, the input port of each group of the connecting cylinder is connected with the output port of each group of the cylinder;

[0012] The spiral conveying device of the Raymond mill of this utility model effectively prevents materials from slipping or getting blocked during the conveying process, ensuring that the materials are conveyed stably and accurately.

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The spiral conveyor of the Raymond mill according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown in the figure, the screw conveyor of the Raymond mill in this embodiment of the present invention may include:

[0027] Main conveyor frame 1;

[0028] The inner wall of the main conveyor frame 1 is provided with multiple sets of cylinders 2;

[0029] The first spiral conveying blade 3 is in multiple sets. Each set of cylinders 2 is rotatably connected to a set of first spiral conveying blades 3. The outer wall of the main conveying frame 1 is fixed with multiple sets of first motors 4. Each set of first motors 4 is connected to one end of the first spiral conveying blade 3.

[0030] Connecting cylinder 5, the input port of each group of connecting cylinder 5 is connected to the output port of each group of cylinder 2 respectively;

[0031] The output port of the connecting cylinder 5 is connected to the interior of the collection rack 6.

[0032] Specifically, for grinding mills producing materials with a high discharge rate and particle diameter of 3mm-5mm, the corresponding first spiral conveying blade 3 can have a larger pitch to quickly convey the material. The corresponding inner diameter of the cylinder 2 is designed to be 250mm, and the length is 2500mm. For grinding mills producing materials with a slower discharge rate and finer particles, the corresponding first spiral conveying blade 3 has a smaller pitch to ensure stable material conveying. The corresponding inner diameter of the cylinder 2 is 150mm, and the length is 1800mm. Multiple sets of first motors 4 are fixed to the outer wall of the main conveyor frame 1. Each set of first motors 4 is connected to one end of the first spiral conveying blade 3. The first motors 4 drive the first spiral conveying blade 3 to rotate inside the cylinder 2, thereby realizing the material conveying. Furthermore, the first motors 4 can be equipped with a frequency converter to flexibly adjust the speed according to the feeding rate.

[0033] In one embodiment of the present invention, a second spiral conveying blade 7 is further included. The second spiral conveying blade 7 is rotatably connected inside the collecting frame 6. A second motor 8 is fixed on the outer wall of the collecting frame 6. The output end of the second motor 8 is connected to one end of the second spiral conveying blade 7.

[0034] Specifically, after the first screw conveying vane 3 converges the materials with different properties into the collection frame 6, the rotation of the second screw conveying vane 7 can deeply mix and homogenize the materials. For example, in the production of ceramic raw materials, the clay, feldspar, quartz and other materials processed by different grinding machines are conveyed to the collection frame 6 by the first screw conveying vane 3. The second screw conveying vane 7 continuously stirs and pushes the materials with different particle sizes and densities to fully interweave, thereby laying a solid foundation for the quality stability of subsequent ceramic products.

[0035] For another use case, in the face of fluctuation in the material flow conveyed by the first screw conveying vane 3, the second screw conveying vane 7 can realize accurate regulation and control with the help of the speed regulation device of the second motor 8. In the pharmaceutical industry, when the raw materials processed by different grinding machines enter the collection frame 6, if the conveying amount of the first screw conveying vane 3 instantaneously increases due to the failure of the upstream equipment, the second motor 8 can quickly increase the rotating speed to 1200 rpm, so as to ensure that the materials pass through the collection frame 6 quickly and orderly, and avoid blockage. When the material amount decreases, the rotating speed can be accurately reduced to 400 rpm, so as to maintain a stable material flow.

[0036] In an embodiment of the present application, a communication frame 9 is further included, and the surface of the communication frame 9 is provided with a plurality of groups of communication pipes 10.

[0037] Specifically, the plurality of groups of powder outlets are used to connect the grinding machines.

[0038] In an embodiment of the present application, the communication pipe 10 is in a cylindrical shape, and the outer wall of the communication pipe 10 is provided with an anti-falling block 11.

[0039] Specifically, the communication pipe 10 can be connected with a hose of the grinding machine, and the anti-falling block 11 can ensure the connection between the communication pipe 10 and the hose.

[0040] In actual use, the materials conveyed by the first screw conveying vane 3 to the collection frame 6 are continuously stirred and pushed by the second screw conveying vane 7, so that the materials with different particle sizes and densities are fully interwoven

[0041] In summary, the screw conveying device of the Raymond grinding machine can effectively prevent the materials from sliding and blocking during the conveying process, and ensure that the materials are stably and accurately conveyed.
