Description

Technical Field

[0001] This utility model relates to the field of expanding agent production technology, specifically to a controllable expanding agent ratio compounding device. Background Technology

[0002] Expansive agents are widely used in many industries such as construction and chemical engineering. Different application scenarios often require compound products of expansive agents with different proportions to achieve specific performance requirements, such as controlling shrinkage cracks in concrete and adjusting the expansion coefficient of materials.

[0003] Chinese patent CN221558295U discloses a utility model relating to the field of expanding agent production technology, specifically an expanding agent metering and proportioning device. The device includes a base plate, a proportioning cylinder fixed to the base plate via several support legs, a stirring mechanism for agitating materials inside the proportioning cylinder, and a weighing cylinder fixed to the top surface of the proportioning cylinder via two fixed columns. A feeding pipe connected to the inner cavity of the proportioning cylinder is fixed to the bottom of the weighing cylinder. This utility model, by setting up a proportioning cylinder, stirring mechanism, and feeding pipe, can stir and mix the expanding agent raw materials added to the proportioning cylinder. By setting up a mounting plate, weighing instrument body, and pushing mechanism, the expanding agent raw materials can be weighed as needed, allowing a specified weight of expanding agent raw material to be added into the proportioning cylinder, thereby improving the performance of the produced expanding agent. It eliminates the need for manual weighing before proportioning, saving time and labor.

[0004] When existing expansion agents are mixed, a single agitator is used to stir the mixture. Due to the different densities of the raw materials, the denser raw materials tend to settle at the bottom of the mixing chamber. The stirring flow generated by the single agitator may not be able to effectively resuspend them and mix them evenly with other raw materials, resulting in an unsatisfactory mixing effect.

[0005] To address the aforementioned issues, a controllable expansion agent ratio compounding device is proposed. Utility Model Content

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1 , Figure 2This utility model discloses a controllable expansion agent ratio compounding device, comprising a controllable expansion agent compounding device body 1, an expansion agent mixing and stirring assembly 2 disposed on the top of the controllable expansion agent compounding device body 1, the expansion agent mixing and stirring assembly 2 including a stirring motor 201 disposed on the top of the controllable expansion agent compounding device body 1, a motor fixing plate 202 fixedly connected to the top of the stirring motor 201, a motor gear 203 fixedly connected to the output end of the stirring motor 201, a main stirring shaft 204 fixedly connected to the bottom of the motor gear 203, a main rotating shaft 205 disposed at the bottom of the main stirring shaft 204, and a fixed connection between the main rotating shaft 205 and the controllable expansion agent compounding device body 1, a transmission gear 206 meshing on the side of the motor gear 203, an auxiliary stirring shaft 207 fixedly connected to the bottom of the transmission gear 206, and the outer wall of the auxiliary stirring shaft 207 fixedly connected to...

The expanding agent proportioning component 3 includes a weighing box 301, which is fixedly connected to the main body 1 of the controllable expanding agent compounding device.

The main stirring shaft 204 forms a rotating structure with the main rotating shaft 205 through a motor gear 203, and the diameter of the motor gear 203 is larger than the diameter of the transmission gear 206.

[0026] When mixing the expanding agent, the stirring motor 201 is started. The stirring motor 201 drives the motor gear 203 and the main stirring shaft 204 to rotate around the main rotating shaft 205. The motor gear 203 drives the transmission gear 206, the auxiliary stirring shaft 207, and the stirring inclined plate 208 to rotate around the auxiliary rotating shaft 209, thus mixing the raw materials inside the device. By setting gears of different sizes, the main stirring shaft 204 and the auxiliary stirring shaft 207 rotate at different speeds, creating a speed difference. At the same time, when the inclined stirring inclined plate 208 rotates, it not only generates axial convection but also radial and tangential flow. This multi-directional flow can make the material form a more complex circulation path in the mixing chamber, thereby effectively avoiding the accumulation of material in local areas or insufficient mixing. The downward flow generated by the inclined stirring inclined plate 208 can re-entrain the settled raw materials into the main mixing stream, ensuring that all raw materials are fully mixed and improving the mixing efficiency of the device.
