Description

Technical Field

[0001] The utility model belongs to the technical field of phase change material premixing, and in particular relates to a full-automatic phase change material premixing device. Background Art

[0002] Phase change materials refer to substances that change their physical state and provide latent heat while keeping the temperature constant. The process of changing physical properties is called phase change. At this time, the phase change material will absorb or release a large amount of latent heat. Phase change materials can be divided into organic and inorganic phase change materials, as well as hydrated salt phase change materials and wax phase change materials.

[0003] A Chinese patent application (CN209791330U) discloses a premixing device for thermal insulation material raw materials. The device comprises a premixing container, a stirring mechanism, and a control unit. The stirring mechanism is disposed within the premixing container and is used to stir the contents. The control unit is electrically connected to the stirring mechanism and controls its on / off function and output power. The control unit controls the stirring mechanism's output power, thereby adjusting the stirring rate within the premixing container to meet the desired stirring rate and stirring time requirements for different raw materials. This allows for precise control of the premixing process, significantly improving the uniformity of the raw materials and effectively preventing damage to the raw materials due to mismatched stirring rates. Furthermore, the device improves the automation and production efficiency of the thermal insulation material production line, ensuring consistent product quality from the source. Phase change material raw materials may clump before premixing. This clumping can lead to uneven premixing, reducing both the quality and efficiency of the premixing process. To address this issue, a fully automatic phase change material premixing device is provided. Utility Model Content

[0004] The purpose of the utility model is to propose a fully automatic phase change material premixing device in order to solve the problem that the current phase change material is easily premixed unevenly and the premixing efficiency is slow due to material agglomeration.

[0005] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a fully automatic phase change material premixing device, comprising a mixing barrel, wherein the upper surface of the mixing barrel is provided with a feed port, a protective cover is fixedly mounted on the upper surface of the mixing barrel, a driving motor is fixedly mounted on the inner wall of the protective cover, a discharge pipe is connected and mounted on the lower surface of the mixing barrel, and a refinement component and a mixing component are provided on the inner wall of the mixing barrel;

[0006] The refinement assembly includes a screening plate and a rotating rod. The outer surface of the screening plate is fixedly connected to the inner wall of the mixing barrel. The upper surface of the screening plate is provided with a discharge port.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

When the rotating rod rotates, it drives the scraper to rotate synchronously, and also drives the push rod to move on the lower surface of the fixed disk through the mounting plate. At this time, under the action of the protrusion, the push rod drives the mounting frame to move up and down under the action of the telescopic spring, thereby driving the pressure roller to move up and down synchronously. The scraper gathers the material under the pressure roller and squeezes the material when the pressure roller moves up and down. The agglomerated material falls to the bottom of the mixing barrel after being squeezed. At the same time, the scraper rotates one circle and the crushed material falls to the bottom of the mixing barrel through the discharge port. The agglomerated material is ground before mixing to make the material particle size almost the same, which is beneficial to improve the uniformity of the phase change material premix and thus improve the quality of the material.

[0019] 2. In the utility model, a mixing assembly is provided. When the scraper rotates, the reciprocating screw is driven to rotate by the connecting rod. Under the action of the thread, the threaded block drives the mixing rod to move up and down in the mixing barrel. When the mixing rod moves up and down, it drives the transmission gear to move on the fixed rack. At this time, the transmission gear drives the mixing rod to rotate to mix the materials. The mixed materials are discharged through the discharge pipe, realizing mixing while rotating while mixing up and down, thereby improving the mixing range of the premixing device. At the same time, mixing at different positions can increase the mixing rate, thereby accelerating the mixing efficiency of the premixing device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation method is as follows: the phase change material is poured into the mixing barrel 1 through the feed port 2. At this time, the phase change material will fall to the upper surface of the screening plate 51. The phase change material with smaller particles will fall directly to the bottom of the mixing barrel 1, and the agglomerated phase change material will remain on the upper surface of the screening plate 51. The driving motor in the protective cover 3 drives the rotating rod 53 to rotate. When the rotating rod 53 rotates, it will drive the scraper 54 to rotate synchronously.

The agglomerated phase change material will remain on the upper surface of the screening plate 51. The driving motor in the protective cover 3 drives the rotating rod 53 to rotate. When the rotating rod 53 rotates, it will drive the scraper 54 to rotate synchronously. At the same time, it will also drive the top rod 59 to move on the lower surface of the fixed disk 510 through the mounting plate 55. At this time, under the action of the protrusion 511, the top rod 59 drives the mounting frame 57 to move up and down under the action of the telescopic spring 56, thereby driving the pressure roller 58 to move up and down synchronously, and the scraper 5 4 The materials are gathered under the pressing roller 58, and the pressing roller 58 is used to squeeze the materials when it moves up and down. The agglomerated materials fall to the bottom of the mixing barrel 1 after being squeezed.
