Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical glass bottle production technology, specifically a stirring device for producing heat insulation materials. Background Technology

[0002] In the production process of thermal insulation materials, the mixing process is crucial and directly affects the quality and performance of the product. Thermal insulation materials are usually made up of a mixture of raw materials with different properties, particle sizes and densities, including fiber materials, foaming agents, binders, etc. These raw materials need to be fully and evenly mixed to ensure that the final product has stable and good thermal insulation performance.

[0003] Traditional mixing devices mostly employ a single rotating mixing mode with a fixed mixing shaft. For complex material systems like thermal insulation materials, this mode has numerous drawbacks. Within the mixing tank, there are significant dead zones in material flow. Relying solely on rotational mixing cannot ensure sufficient contact and mixing of raw materials in all areas. In particular, materials with higher density or stronger viscosity tend to accumulate at the bottom or corners of the mixing tank, making them difficult to mix evenly. This results in large fluctuations in product quality, making it difficult to meet ideal standards in key indicators such as thermal insulation performance and strength.

[0004] Therefore, we propose a novel stirring device for the production of thermal insulation materials. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a design that allows for both vertical and horizontal stirring while rotating, continuously altering the material's flow path. Materials that were previously difficult to stir and were concentrated in corners or near the tank walls are forcibly drawn into the stirring area, promoting vertical convection within the mixing tank. Under the influence of convection, materials at different levels exchange positions more quickly, further enhancing the mixing effect. This is especially beneficial for raw materials with significantly different properties in insulation materials, allowing them to come into contact more quickly and comprehensively, thereby significantly improving mixing efficiency, reducing stirring time, and increasing production efficiency while ensuring product quality.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-7As shown, this utility model provides a technical solution: a stirring device for producing heat insulation materials, including a shell 1, a second rotating rod 6 mounted on the upper end of the shell 1 via a bearing, a stirring motor 9 fixedly mounted on the upper end of the second rotating rod 6, the bottom end of the second rotating rod 6 extending into the interior of the shell 1 and slidably connected to a first rotating rod 4, a limiting member provided between the second rotating rod 6 and the first rotating rod 4, a plurality of first stirring shafts 5 and second stirring shafts 13 fixedly mounted on the outer surface of the first rotating rod 4, a sliding groove 401 with a T-shaped longitudinal section opened on the upper end of the first rotating rod 4, the bottom end of the second rotating rod 6 extending into the sliding groove 401 and fixedly mounted with a limiting block 601, upper and lower springs 16 fixedly mounted on the upper end of the first rotating rod 4, the upper and lower springs 16 sleeved on the outer surface of the second rotating rod 6, an upper mounting plate 8 fixedly mounted on the upper end of the upper and lower springs 16, the upper mounting plate 8 fixedly mounted on the outer surface of the second rotating rod 6, a lower pressing member 7 provided at the bottom end of the upper mounting plate 8, and a crushing member provided inside the shell 1;

[0026] A feed pipe 2 is fixedly installed at the upper end of the outer casing 1, and a discharge pipe 3 is fixedly installed at the bottom end of the outer casing 1.

[0027] In an optional embodiment: the pressing member 7 includes a guide block 701, a rolling ball 702 and a connecting rod 703. The connecting rod 703 is fixedly installed at the bottom end of the upper mounting plate 8, the rolling ball 702 is fixedly installed at the bottom end of the connecting rod 703, and the bottom end of the guide block 701 is fixedly installed with a lower mounting plate 403. The lower mounting plate 403 is fixedly installed at the upper end of the first rotating rod 4.

[0028] It should be noted that when the upper mounting plate 8 rotates, it can also rotate the connecting rod 703 and the rolling ball 702. When the rolling ball 702 moves along the inclined wall of the guide block 701, it can move downward against the guide block 701, thereby causing the first rotating rod 4 to move downward, which stretches the upper and lower springs 16. When the rolling ball 702 passes the guide block 701, it moves upward with the first rotating rod 4 under the elastic force of the upper and lower springs 16.

[0029] In an optional embodiment: the limiting member includes a limiting groove 402, which is formed at the upper end of the first rotating rod 4. The limiting groove 402 communicates with the sliding groove 401. A limiting strip 602 is slidably connected in the limiting groove 402. The limiting strip 602 is fixedly installed on the outer surface of the second rotating rod 6.

[0030] It should be noted that, with the cooperation of the limiting slide bar 602 and the limiting slide groove 402, the first rotating rod 4 will not rotate while the second rotating rod 6 is rotating.

[0031] In an optional embodiment: the crushing component includes a filter screen 14, a connecting rod 2 10 and a crushing roller 11. The filter screen 14 is fixedly installed on the inner side wall of the outer casing 1. The connecting rod 2 10 is rotatably installed on the outer side wall of the second rotating rod 6. The crushing roller 11 is fixedly installed on the outer surface of the connecting rod 2 10. One end of the connecting rod 2 10 is provided with a rotating component 12.

[0032] It should be noted that materials that are clumped together or have large particles are placed on the upper part of the filter screen plate 14. When the second rotating rod 6 rotates, it will also cause the crushing roller 11 to rotate. When the crushing roller 11 rotates, it will break the clumped or large particles into the required particle size, making the raw materials more delicate and helping to mix and react better with other raw materials.

[0033] In an optional embodiment: the rotating member 12 includes an annular groove 121, a gear 122 and an annular tooth groove 123. The annular groove 121 is formed inside the housing 1. The annular tooth groove 123 is fixedly installed at the bottom end of the annular groove 121. The gear 122 is fixedly installed at the side end of the connecting rod 10. The annular tooth groove 123 is meshed with the gear 122.

[0034] It should be noted that when the rolling mill 11 rotates, the gear 122 also rotates in the annular groove 121. Under the action of the annular tooth groove 123, the gear 122 can rotate, which in turn causes the connecting rod 10 to rotate, thereby rotating the rolling mill 11.

[0035] In an optional embodiment: a motor plate 15 is fixedly mounted on the upper end of the stirring motor 9, and the motor plate 15 is fixedly mounted on the upper end of the outer casing 1.

[0036] It should be noted that the stirring motor 9 is installed on the upper part of the outer casing 1.

[0037] In an optional embodiment: a cleaning groove 101 is provided at the upper end of the outer casing 1, and a sealing door 102 is provided at the upper end of the cleaning groove 101, and the sealing door 102 is hinged to the upper end of the outer casing 1.

[0038] It should be noted that the filter screen 14 can be cleaned periodically through the cleaning tank 101, or if there are any impurities inside that cannot be broken down, they can be cleaned to prevent clogging.

[0039] In practical use, the working principle of this utility model is as follows:

[0040] The heat insulation material is introduced into the outer shell 1 in batches through the feed pipe 2. Materials with normal particle size or no clumps pass through the filter screen 14. At this time, the stirring motor 9 starts, and the output end of the stirring motor 9 rotates, causing the second rotating rod 6 to rotate. During the rotation of the second rotating rod 6, with the cooperation of the limiting slide bar 602 and the limiting slide groove 402, it can continue to rotate the first stirring shaft 5, further rotating the material entering the outer shell 1, completing the rotation and stirring of the material. When the second rotating rod 6 rotates, it will also cause the upper mounting plate 8 to continue rotating. Simultaneously, the upper mounting plate 8 rotates, causing the connecting rod 703 and the rolling ball 702 to rotate as well. When the rolling ball 702 moves along the inclined wall of the guide block 701, it can move downward against the guide block 701, thereby causing the first rotating rod 4 to move downward, which stretches the upper and lower springs 16. When the rolling ball 702 passes the guide block 701, under the elastic force of the upper and lower springs 16, it carries the first rotating rod 4 upward. During the up and down movement, the flow path of the material is constantly changed. The material that was originally gathered in the corner or near the tank wall and was difficult to be stirred is forcibly drawn into the stirring range, making the stirring deeper and wider, and fully dispersing and blending the material. After the stirring is finished, it is discharged through the discharge pipe 3. The discharge of the discharge pipe 3 can be achieved by installing a valve on it.

[0041] Materials that are clumped together or have large particles flow onto the upper part of the filter screen plate 14. When the second rotating rod 6 rotates, it also drives the crushing roller 11 to rotate. When the crushing roller 11 rotates, the gear 122 also rotates in the annular groove 121. Under the action of the annular tooth groove 123, the gear 122 can rotate, which further causes the connecting rod 10 to rotate, thereby driving the crushing roller 11 to rotate. The rotating crushing roller 11 can break the clumped or large particles into the required particle size, making the raw materials finer and helping to mix and react better with other raw materials.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
