Description

Technical Field

[0001] The present invention relates to the technical field of ceramic processing, and particularly to a lead-free ceramic raw material mixer. Background Art

[0002] Lead-free ceramic raw materials are an environmentally friendly material, mainly used for manufacturing lead-free piezoelectric ceramics. It does not contain lead elements, avoiding the harm of lead toxicity to human health and the ecological environment. Common lead-free ceramic raw materials include barium titanate, sodium potassium niobate, bismuth layer structure compounds, etc. These materials have a perovskite structure or a bismuth layer structure. Through specific preparation processes, lead-free piezoelectric ceramics with excellent performance can be made and widely used in electronic components such as sensors, resonators, and filters.

[0003] In current ceramic processing production, the design of the ceramic raw material mixer used has limitations, mainly manifested as a single structure and a fixed stirring direction, which greatly limits the flexibility and efficiency of stirring. Especially with a fixed stirring direction, it is easy to cause the material to accumulate in certain areas, making it difficult to achieve uniform mixing in all directions and difficult to ensure the uniformity and fineness of the raw material mixing. In addition, although the raw materials need to be screened to remove impurities and large particles before stirring, it is inevitable that there will be omissions in actual operation. Due to the physical property differences of the raw materials and the limitations of manual operation, it is still inevitable that some impurities and particles are not completely screened out. These unscreened particles and impurities will affect the quality of the ceramic finished product. Therefore, a lead-free ceramic raw material mixer is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, mainly manifested as a single structure and a fixed stirring direction, which greatly limits the flexibility and efficiency of stirring. Especially with a fixed stirring direction, it is easy to cause the material to accumulate in certain areas, making it difficult to achieve uniform mixing in all directions. Due to the physical property differences of the raw materials and the limitations of manual operation, it is still inevitable that some impurities and particles are not completely screened out, and to propose a lead-free ceramic raw material mixer.

The rotation of the mixing rod drives the mixing plates on the mixing rod to rotate, and the rotation of the mixing rod drives the mixing blades to rotate accordingly. The rotating mixing blades rotate self-reliantly through the fixed rods, so that the mixing blades and the mixing plates on the mixing rods stir the materials in different directions respectively. The rotation of the rotating rod and the threaded blade transports the materials at the bottom to the upper part, so that the materials are circularly stirred. Jitter assemblies are symmetrically arranged inside the mixing tank. The two jitter assemblies include a connecting block and a movable rod that are movably connected inside the mixing tank, and a filter plate that is movably connected inside the mixing tank.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] Such as Figures 1 - 7As shown in the figure, a lead-free ceramic raw material mixer proposed by the present invention includes a mixing tank 1. A mixing assembly is provided on the mixing tank 1. The mixing assembly includes mixing blades 11, mixing rods 4 and fixing rods 10 that are symmetrically and rotatably connected inside the mixing tank 1, and a rotating rod 6 and a threaded blade 7 that are rotatably connected inside the mixing tank 1. The rotation of the mixing rod 4 drives the mixing plates on the mixing rod 4 to rotate. The rotation of the mixing rod 4 drives the mixing blades 11 to rotate accordingly. The rotating mixing blades 11 rotate self-rotationally through the fixing rods 10, so that the mixing blades 11 and the mixing plates on the mixing rods 4 stir the materials in different directions respectively. The rotation of the rotating rod 6 and the threaded blade 7 transports the materials at the bottom to the upper part, so that the materials are cyclically stirred. Jitter assemblies are symmetrically arranged inside the mixing tank 1. The two jitter assemblies include a connecting block 23 and a movable rod 27 that are movably connected inside the mixing tank 1, and a filter plate 17 that is movably connected inside the mixing tank 1. The rotation of the mixing rod 4 drives the connecting block 23 to rotate. The rotation of the connecting block 23 drives the movable rod 27 to move up and down. The up and down movement of the movable rod 27 causes the filter plate 17 to move accordingly, so that the materials are screened and fully and evenly fused through the filter plate 17.

[0031] A first motor 3 is fixedly connected to the upper part of the mixing tank 1. The end of the output shaft of the first motor 3 is fixedly connected to a first gear 19. One end of the mixing rod 4 close to the first motor 3 is fixedly connected to a second gear 20. The start of the first motor 3 drives the first gear 19 to rotate. The rotation of the first gear 19 drives the mixing rod 4 to rotate through the second gear 20.

[0032] The first gear 19 meshes with the second gear 20. The mixing rod 4 is movably connected to the fixing rod 10. A support plate 2 is fixedly connected to one side of the mixing tank 1 close to the first motor 3. The rotation of the mixing rod 4 drives the mixing plates on the mixing rod 4 to stir the raw materials in the mixing tank 1.

[0033] The fixing rod 10 is fixedly connected to the support plate 2. First helical gears 12 are symmetrically and fixedly connected to the outside of the fixing rod 10. Second helical gears 13 are fixedly connected to one side of the mixing blades 11 close to the first helical gears 12.

[0035] The end of the output shaft of the second motor 5 is fixedly connected to the rotating rod 6, and the rotating rod 6 is fixedly connected to the threaded blade 7. A circulating feed port 8 is provided inside the mixing tank 1. The start of the second motor 5 drives the rotating rod 6 to rotate, and the rotation of the rotating rod 6 drives the threaded blade 7 to rotate accordingly.

[0036] In this embodiment, the material is fed through the feeding port on the mixing tank 1 so that the material enters the inside of the mixing tank 1. At this time, the start of the first motor 3 drives the first gear 19 to rotate. The rotation of the first gear 19 drives the mixing rod 4 to rotate through the second gear 20. The rotation of the mixing rod 4 drives the mixing plate on the mixing rod 4 to stir the raw materials in the mixing tank 1. Moreover, the rotation of the mixing rod 4 drives a plurality of mixing blades 11 to rotate accordingly. The rotation of the mixing blades 11 rotates self - by means of the second bevel gear 13 and the first bevel gear 12. In this way, the mixing plate and the mixing blades 11 on the mixing rod 4 stir the materials inside the mixing tank 1 in different directions respectively. When the raw materials at the bottom of the mixing tank 1 pass through the funnel plate 14 and reach the threaded blade 7 through the first channel 9, the start of the second motor 5 drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 drives the threaded blade 7 to rotate accordingly. The rotation of the threaded blade 7 makes the material enter the mixing tank 1 again through the circulating feed port 8. In this way, the raw materials are circularly stirred to make the raw materials fully stirred and evenly mixed.

A piston 16 is movably connected inside the second channel 15. An electric valve 18 is movably connected to the side of the first channel 9. When the electric valve 18 is opened, the evenly - stirred material can pass through.

[0039] One end of the mixing rod 4 far from the first motor 3 is fixedly connected with a third bevel gear 21. A fixed plate 26 is fixedly connected inside the mixing tank 1. A fourth bevel gear 22 is rotatably connected to the outside of the fixed plate 26. The fourth bevel gear 22 meshes with the third bevel gear 21. A movable rod 27 is movably connected to the fixed plate 26. The rotation of the third bevel gear 21 drives the fourth bevel gear 22 to rotate, and the rotation of the fourth bevel gear 22 drives the connecting block 23 to rotate accordingly.

[0040] One end of the fourth bevel gear 22 far from the third bevel gear 21 is fixedly connected to the connecting block 23. One end of the connecting block 23 far from the fourth bevel gear 22 is movably connected to a connecting rod 24. One end of the connecting rod 24 far from the connecting block 23 is movably connected to the movable rod 27. The filter plate 17 moves up and down following the movable rod 27.

A spring 25 is fixedly connected to the outside of the fixed plate 26, and the spring 25 is fixedly connected to the movable rod 27. The movement of the movable rod 27 is made more stable by the spring 25.

[0042] In this embodiment, as described in the previous step, the material is collected at the bottom through the funnel plate 14. At this time, the rotation of the stirring rod 4 drives the rotation of the third bevel gear 21, the rotation of the third bevel gear 21 drives the rotation of the fourth bevel gear 22, and the rotation of the fourth bevel gear 22 drives the connecting block 23 to rotate accordingly. The rotation of the connecting block 23 drags the movable rod 27 to move up and down through the connecting rod 24. The movement of the movable rod 27 is made more stable by the spring 25. The filter plate 17 moves up and down following the movable rod 27, enabling the material to be screened and fully and evenly mixed through the filter plate 17. At this time, the opening of the electric valve 18 allows the evenly stirred material to pass through, thereby collecting the stirred material. At this time, the unqualified or larger materials stay above the filter plate 17. When the material collection is completed, by pulling the piston 16 outwards, the unqualified or larger materials roll out of the mixing tank 1 through the second channel 15.
