Description

Technical Field

[0001] This utility model belongs to the field of stirring rack technology, and specifically relates to a screw stirring structure. Background Technology

[0002] In many industrial production fields, such as chemical, food, pharmaceutical and building materials, mixing operations occupy an extremely important position. The core purpose of mixing is to promote the uniform mixing of materials, enhance the mass and heat transfer process, and thus improve production efficiency and product quality. Therefore, the mixing structure, as an important component of mixing equipment, plays a unique role in many scenarios.

[0003] For example, Chinese patent CN218505182U discloses a high wear-resistant alloy barrel screw, including a screw body, with multiple screw ribs fixedly connected to the outer wall of the screw body, and multiple stirring blocks fixedly connected to the outer wall of the screw body.

[0004] While the aforementioned patents have solved the problems of convenient operation and easy replacement and maintenance, the existing spiral stirring structure still has some defects that need to be improved. In actual industrial production, relying solely on a single spiral stirring blade to stir the material results in a relatively simple flow field, making it difficult to achieve a full and efficient mixing effect, which leads to a significant increase in mixing time and thus low production efficiency. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a screw stirring structure to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A screw stirring structure includes an assembly base plate, a drive motor fixedly connected to the top of the assembly base plate, a spiral stirring blade provided at the output end of the drive motor, a transmission stirring sleeve rotatably connected to the assembly base plate outside the spiral stirring blade, the transmission stirring sleeve being located outside the spiral stirring blade, a first stirring frame fixedly connected to the inner wall of the transmission stirring sleeve, a second stirring frame fixedly connected to the outer wall of the transmission stirring sleeve, a transmission assembly provided below the assembly base plate on one side of the drive motor, a limiting guide assembly provided on the upper side of the transmission stirring sleeve, and discharge holes provided on both sides of the transmission stirring sleeve.

[0008] As a preferred technical solution, the first stirring rack includes a first side plate, which is fixedly connected to the outer wall of the transmission stirring sleeve. The first side plate has through holes inside, and there are multiple through holes.

[0009] As a preferred technical solution, the second stirring rack includes a second side plate, which is fixedly connected to the inner wall of the transmission stirring sleeve. Both sides of the second side plate are fixedly connected with protrusions, and multiple sets of protrusions are provided.

[0010] As a preferred technical solution, the transmission assembly includes a drive gear, which is fixedly connected to the output end of the drive motor. A driven gear is meshed with one side of the drive gear, and a gear ring is meshed with one side of the driven gear. The gear ring is fixedly connected to the top of the transmission stirring sleeve. The gear ring is rotatably connected to the lower side of the mounting base plate through a limiting guide assembly. A transmission rod is fixedly connected to the output end of the drive motor near the drive gear, and the spiral stirring blade is fixedly connected to the transmission rod.

[0011] As a preferred technical solution, the limiting and guiding assembly includes a guide groove, which is formed inside the lower side of the assembly base plate. A guide ring is slidably connected inside the guide groove. One side of the guide ring is fixedly connected to one side of the transmission stirring sleeve. A limiting groove is formed inside the guide groove. A limiting ring is slidably connected inside the limiting groove. One side of the limiting ring is fixedly connected to one side of the guide ring.

[0012] In summary, the present invention has the following main advantages:

[0013] First, this utility model, by setting a spiral stirring blade and setting a transmission stirring sleeve outside the spiral stirring blade, fixes a first stirring frame to the outer wall of the transmission stirring sleeve and a second stirring frame to the inner wall of the transmission stirring sleeve. When the spiral stirring blade and the transmission stirring sleeve rotate synchronously, the flow fields generated by the two interfere with each other. The first stirring frame on the outer wall of the transmission stirring sleeve stirs the outer layer of material, and the second stirring frame on the inner wall stirs the inner layer of material. Under this multi-dimensional flow field, the material can be stirred in a shorter time, the reaction is more complete and faster, and the mixing effect is improved.

[0014] Secondly, by setting up a transmission component and a limiting guide component, this utility model enables one drive motor to drive the spiral stirring blade, the first stirring frame, and the second stirring frame to rotate synchronously, which simplifies the power structure of the equipment, reduces the number of drive motors, and lowers the manufacturing cost and maintenance difficulty of the equipment.

[0020] Example

[0021] refer to Figures 1 to 4 The screw stirring structure described in this embodiment includes an assembly base plate 1. A drive motor 2 is fixedly connected to the top of the assembly base plate 1. The output end of the drive motor 2 is provided with a spiral stirring blade 3. A transmission stirring sleeve 4 is rotatably connected to the assembly base plate 1 outside the spiral stirring blade 3. The transmission stirring sleeve 4 is located outside the spiral stirring blade 3. A first stirring frame 5 is fixedly connected to the inner wall of the transmission stirring sleeve 4, and a second stirring frame 6 is fixedly connected to the outer wall of the transmission stirring sleeve 4. A transmission component 8 is provided on one side of the drive motor 2 below the assembly base plate 1. A limiting guide component 9 is provided on the upper side of the transmission stirring sleeve 4. Discharge holes 7 are opened on both sides of the transmission stirring sleeve 4. With the above settings, under this multi-dimensional flow field, material stirring can be achieved in a shorter time, the reaction is more complete and faster, and the mixing effect is improved.

[0022] refer to Figure 2 The first stirring frame 5 includes a first side plate 51, which is fixedly connected to the outer wall of the transmission stirring sleeve 4. The first side plate 51 has through holes 52 inside, and there are multiple through holes 52. When the transmission stirring sleeve 4 rotates, the first side plate 51 moves synchronously with it. During the flow of material in the inner layer, part of it forms a jet stream through the through holes 52 on the first side plate 51, which improves the mixing effect.

[0023] refer to Figure 2 The second stirring frame 6 includes a second side plate 61, which is fixedly connected to the inner wall of the transmission stirring sleeve 4. Both sides of the second side plate 61 are fixedly connected to protrusions 62, and multiple sets of protrusions 62 are provided. When the transmission stirring sleeve 4 rotates, the second side plate 61 drives the protrusions 62 to rotate synchronously. When the protrusions 62 move in the material, they generate periodic disturbances to the surrounding fluid. The disturbances induce vortices inside the material, which, together with the spiral stirring blades 3, stir the material.

[0024] refer to Figure 3The transmission assembly 8 includes a drive gear 82, which is fixedly connected to the output end of the drive motor 2. A driven gear 83 is meshed with one side of the drive gear 82, and a gear ring 84 is meshed with one side of the driven gear 83. The gear ring 84 is fixedly connected to the top of the transmission stirring sleeve 4 and is rotatably connected to the lower side of the mounting base plate 1 through a limiting guide assembly 9. A transmission rod 81 is fixedly connected to the output end of the drive motor 2 near the drive gear 82, and the spiral stirring blade 3 is fixedly connected to the transmission rod 81. By setting the transmission assembly 8, the drive motor 2 drives the drive gear 82 to rotate, the drive gear 82 drives the driven gear 83 to rotate, and the driven gear 83 drives the gear ring 84 to rotate, thereby driving the transmission stirring sleeve 4 to rotate, realizing the simultaneous operation of multiple stirring structures.

[0025] refer to Figure 4 The limiting and guiding component 9 includes a guide groove 91, which is formed inside the lower side of the assembly base plate 1. A guide ring 92 is slidably connected inside the guide groove 91, and one side of the guide ring 92 is fixedly connected to one side of the transmission stirring sleeve 4. A limiting groove 93 is formed inside the guide groove 91, and a limiting ring 94 is slidably connected inside the limiting groove 93. One side of the limiting ring 94 is fixedly connected to one side of the guide ring 92. By setting the limiting and guiding component 9, when the transmission stirring sleeve 4 rotates, the guide ring 92 slides in the guide groove 91, and the limiting ring 94 slides synchronously in the limiting groove 93, preventing the transmission stirring sleeve 4 from axially moving, thereby facilitating the rotation of the transmission stirring sleeve 4.

[0026] Operating principle and advantages: When the drive motor 2 is started, it drives the transmission rod 81 to rotate, causing the spiral stirring blades 3 to begin rotating. Simultaneously, the drive motor 2 drives the fixed drive gear 82 at the output end to rotate. The drive gear 82 drives the driven gear 83 to rotate, transmitting power to the driven gear 83. The driven gear 83 then meshes with the gear ring 84, driving the gear ring 84 fixed at the top of the transmission stirring sleeve 4 to rotate, thereby driving the transmission stirring sleeve 4 to rotate. During the rotation of the transmission stirring sleeve 4, the second side plate 61 of the second stirring frame 6 fixed on the inner wall drives the protrusion 62 to rotate synchronously. The protrusion 62 moves in the material, generating periodic disturbances to the surrounding fluid, inducing vortices inside the material, and enhancing the stirring effect. The first side plate of the first stirring frame 5 fixed on the outer wall... 51 also moves synchronously with the transmission stirring sleeve 4. When the material flows in the inner layer, part of it forms a jet stream through multiple through holes 52 on the first side plate 51, colliding and mixing with the surrounding material. During this period, the guide rings 92 on both sides of the transmission stirring sleeve 4 slide in the guide groove 91 on the lower side of the assembly base plate 1, and the limiting rings 94 slide synchronously in the limiting groove 93, limiting the radial and axial displacement of the transmission stirring sleeve 4 and ensuring the stable rotation of the transmission stirring sleeve 4. Under the combined action of the spiral stirring blades 3, the first stirring frame 5 and the second stirring frame 6, the material forms a multi-dimensional complex flow field. Whether it is processing multi-component solutions in the chemical industry or high-viscosity sauces in the food industry, it can significantly shorten the mixing time, improve the reaction sufficiency, significantly improve the product mixing uniformity, and reduce the defect rate.
