Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid waste-based soil solidification production technology, and in particular to a raw material mixing device. Background Technology
[0002] Solid waste-based soil solidification production is a technology that uses certain components from industrial solid waste or municipal solid waste as the main raw materials to prepare soil and then applies it to soil solidification. In the production process, a mixing device is usually used to mix the raw materials.
[0003] However, existing technologies have some problems: existing raw material mixing devices usually pour the raw materials directly into the mixing chamber for mixing. However, there may be large solid pieces in the raw materials, which require a long time to mix and can easily damage the mixing blades. At the same time, existing raw material mixing devices directly pour the additives into the mixing chamber, making it difficult to control the additive ratio and the mixing speed is slow. Therefore, we propose a raw material mixing device. Summary of the Invention

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.
[0022] like Figures 1 to 4 As shown in the figure, the present invention provides a raw material mixing device, including a support 1, which is welded from multiple sets of stainless steel pipes. The main function of the support 1 is to support the entire device and ensure its stable operation.
[0023] Furthermore, a conveyor platform 2 is fixedly connected to the support 1, and the conveyor platform 2 is equipped with a conveyor belt 3. The conveyor belt 3 is used to transport the raw materials crushed by the crushing platform 4 to the mixing chamber 11 for mixing.
[0024] Furthermore, a crushing table 4 is fixedly connected to the conveyor table 2, and a feed hopper 10 is fixedly connected to the crushing table 4. The feed hopper 10 is funnel-shaped and is used to add raw materials to the device.
[0025] Furthermore, a crushing assembly 6 is provided inside the crushing table 4. The crushing assembly 6 includes a first rotating shaft 61 and a second rotating shaft 62. Both the first rotating shaft 61 and the second rotating shaft 62 are rotatably connected inside the crushing table 4. Crushing blades 63 are fixedly connected to both the first rotating shaft 61 and the second rotating shaft 62. The crushing blades 63 are arranged alternately. A baffle 64 is fixedly connected to the inner wall of the crushing table 4. The baffle 64 is set in the gap between the crushing blades 63 and the crushing table 4 to prevent uncrushed raw materials from leaking out of the crushing table 4 through the gap.
[0026] Furthermore, a first motor 65 is fixedly connected to the crushing table 4, and a first rotating shaft 61 is connected to the output end of the first motor 65 via a coupling. A first gear 66 is fixedly connected to one end of the first rotating shaft 61, and a second gear 67 is fixedly connected to one end of the second rotating shaft 62. The first gear 66 and the second gear 67 mesh.
[0027] Specifically, when raw materials are added to the device through the feed hopper 10, the first motor 65 starts and drives the first rotating shaft 61 to rotate. The first rotating shaft 61 then drives the first gear 66 to rotate, which in turn drives the second gear 67 to rotate, thereby causing the second rotating shaft 62 to rotate. This, in turn, causes the crushing blades 63 fixedly connected to the first rotating shaft 61 and the second rotating shaft 62 to rotate, thereby crushing the raw materials and accelerating the subsequent stirring speed.
[0028] Furthermore, a support frame 7 is fixedly connected to the conveyor table 2, a material conveying cylinder 8 is fixedly connected to the support frame 7, a material conveying assembly 9 is provided on the material conveying cylinder 8, the material conveying assembly 9 includes an outlet 91 and an inlet 92, the outlet 91 and the inlet 92 are respectively fixedly connected to the two ends of the material conveying cylinder 8, and a storage tank 93 is fixedly connected to the inlet 92.
[0029] Specifically, multiple sets of support frame 7, conveying cylinder 8 and conveying assembly 9 are provided. Storage tank 93 is used to store additives such as curing agent and stabilizer. Discharge port 91 is located directly above the middle of conveyor belt 3 and is used to convey additives to raw materials.
[0030] Furthermore, a conveying shaft 94 is rotatably connected inside the conveying cylinder 8, a spiral blade 95 is fixedly connected to the outer wall of the conveying shaft 94, a second motor 96 is fixedly connected to the conveying cylinder 8, and the conveying shaft 94 is connected to the output end of the second motor 96 through a coupling.
[0031] Specifically, after the raw materials are crushed by the crushing component 6, they need to be transported to the mixing chamber 11 by the conveyor belt 3 on the conveyor table 2 for mixing. At this time, the second motor 96 starts and drives the conveying shaft 94 to rotate. The conveying shaft 94 then drives the spiral blade 95 to rotate, thereby conveying the additive in the storage tank 93 from the discharge port 91 to the raw materials, accelerating the subsequent mixing rate. At the same time, by controlling the speed of the second motor 96, the conveying rate of the additive can be controlled, thereby controlling the proportion of the additive.
[0032] Furthermore, a mixing chamber 11 is fixedly connected to the support 1, and a mixing component 5 is provided on the mixing chamber 11. A discharge hole is opened at one end of the mixing chamber 11, which is used to discharge the mixed raw materials from the mixing chamber 11.
[0033] Specifically, the stirring assembly 5 includes a first stirring shaft 51 and a second stirring shaft 52. Both the first stirring shaft 51 and the second stirring shaft 52 are rotatably connected in the stirring chamber 11. Both the first stirring shaft 51 and the second stirring shaft 52 are fixedly connected with stirring blades 53, which are arranged alternately.
[0034] Furthermore, the stirring assembly 5 also includes a third motor 54, and a first stirring shaft 51 is connected to the output end of the third motor 54 via a coupling. A third gear 55 is fixedly connected to one end of the first stirring shaft 51, and a fourth gear 56 is fixedly connected to one end of the second stirring shaft 52. The third gear 55 and the fourth gear 56 mesh.
[0035] Specifically, after the conveyor belt 3 transports the crushed and additive-added raw materials into the mixing chamber 11, the third motor 54 starts and drives the first mixing shaft 51 to rotate. After the first mixing shaft 51 rotates, it drives the third gear 55 to rotate. The third gear 55 then drives the fourth gear 56 to rotate, thereby causing the second mixing shaft 52 to rotate synchronously. This causes the mixing blades 53 on the first mixing shaft 51 and the second mixing shaft 52 to rotate, thus mixing the raw materials transported into the mixing chamber 11 evenly.
[0036] The working principle of this utility model is as follows:
[0037] This utility model is equipped with a crushing component 6. When raw materials are added to the device through the feed hopper 10, the first motor 65 starts and drives the first rotating shaft 61 to rotate. The rotation of the first rotating shaft 61 drives the first gear 66 to rotate, and the first gear 66 drives the second gear 67 to rotate, thereby causing the second rotating shaft 62 to rotate. This, in turn, causes the crushing blades 63 fixedly connected to the first rotating shaft 61 and the second rotating shaft 62 to rotate, thereby crushing the raw materials and accelerating the subsequent stirring speed.
[0038] This utility model is equipped with a material conveying component 9. After the raw material is crushed by the crushing component 6, it needs to be conveyed to the mixing chamber 11 by the conveyor belt 3 on the conveying platform 2 for mixing. At this time, the second motor 96 starts and drives the material conveying shaft 94 to rotate. The material conveying shaft 94 then drives the spiral blade 95 to rotate, thereby conveying the additive in the storage tank 93 from the discharge port 91 to the raw material, accelerating the subsequent mixing rate. At the same time, by controlling the speed of the second motor 96, the conveying rate of the additive can be controlled, thereby controlling the proportion of the additive.

It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
