Description

Technical Field

[0001] This utility model relates to the technical field of building material processing equipment, specifically a mixing and stirring device for environmentally friendly thermal insulation materials used in buildings. Background Technology

[0002] In the construction process, the application of environmentally friendly thermal insulation materials is becoming increasingly widespread. The quality of their mixing directly affects the construction effect and thermal insulation performance of the project. Currently, traditional mixing devices on the market generally have the following problems: First, insulation material easily remains on the inner wall of the mixing chamber, not only causing material waste but also affecting the mixing purity of subsequent batches; second, the mixing method is mostly unidirectional rotational mixing, which easily leads to the formation of vortex-like accumulation of materials within the chamber, resulting in insufficient uniformity of mixing of different components of the insulation material; third, for some environmentally friendly thermal insulation materials containing fibrous components, traditional mixing devices struggle to achieve uniform fiber dispersion, easily causing fiber agglomeration and reducing the overall performance of the insulation material. To address the aforementioned technical problems, this utility model proposes a mixing and stirring device for environmentally friendly building insulation materials. By optimizing the mixing structure and cleaning design, it improves the uniformity of material mixing, reduces material residue, and meets the high-efficiency mixing requirements of environmentally friendly building insulation materials.

[0015] Please see Figure 1-4This utility model provides a technical solution: a mixing device for environmentally friendly thermal insulation materials used in construction, comprising a mixing chamber 1, a support base 2, a drive assembly, and a cleaning assembly. The support base 2 is fixedly installed on the lower side of the mixing chamber 1, the drive assembly is located on the top of the mixing chamber 1, and the cleaning assembly is fitted against the inner wall of the mixing chamber 1. A shock-absorbing pad is provided at the bottom of the support base 2. The shock-absorbing pad is made of nitrile rubber and has anti-slip textures on its bottom to reduce vibration and displacement during device operation.

[0016] The mixing tank 1 has a feed inlet 8 at the top and a discharge outlet 9 at the center of the bottom. An electrically controlled valve is installed at the discharge outlet 9. The inner wall of the mixing tank 1 is covered with a wear-resistant coating, and the surface of the wear-resistant coating has a smooth arc-shaped structure, which reduces the material adhesion area and reduces the friction and wear of the material on the inner wall.

[0017] The drive assembly includes a drive motor 3, a transmission shaft 4, and a stirring frame 5. The drive motor 3 is fixed to the top of the mixing chamber 1 by a motor bracket. One end of the transmission shaft 4 is connected to the output end of the drive motor 3 by a coupling, and the other end extends through the top of the mixing chamber 1 into the interior of the mixing chamber 1. The stirring frame 5 is fixed to the outside of the transmission shaft 4. The stirring frame 5 includes a main stirring rod 51 and an auxiliary stirring rod 52. The main stirring rod 51 is arranged radially along the transmission shaft 4. The auxiliary stirring rod 52 is inclined at a 45° angle to the main stirring rod 51, and a number of dispersion holes 53 are opened on the surface of the auxiliary stirring rod 52.

[0018] Both the main stirring rod 51 and the auxiliary stirring rod 52 are made of stainless steel, and their surfaces are treated with anti-corrosion coating to extend the service life of the device and adapt to acidic or alkaline environments for environmentally friendly insulation materials. The auxiliary stirring rod 52 is cylindrical, and the dispersion holes 53 are evenly distributed on it, enabling multi-directional stirring of materials and improving the uniformity of material mixing.

[0019] The cleaning assembly includes an annular cleaning frame 6 and an elastic scraper 7. The annular cleaning frame 6 is sleeved on the outside of the drive shaft 4 and is fixedly connected to the drive shaft 4 via a second stirring blade 12. The elastic scraper 7 is fixed to the outside of the annular cleaning frame 6 and fits tightly against the inner wall of the mixing chamber 1. The elastic scraper 7 is made of wear-resistant rubber to ensure cleaning effectiveness while avoiding excessive friction. The second stirring blade 12 is symmetrically arranged at an inclined center on the inner side of the annular cleaning frame 6, and the second stirring blade 12 and the annular cleaning frame 6 form an integrated structure. The rotation of the annular cleaning frame 6 also has a stirring effect through the second stirring blade 12, increasing the functionality of the annular cleaning frame 6.

[0020] An observation window is also provided on the outside of the mixing chamber 1. The observation window is made of high-temperature resistant transparent glass and has a sealing strip on the edge, which facilitates observation of the mixing state of the materials inside the chamber and ensures that the chamber is sealed.

[0021] The top of the mixing tank 1 is also provided with a pressure relief port 10, and a pressure valve is installed on the pressure relief port 10. When the pressure inside the mixing tank 1 exceeds the preset value, the pressure valve will automatically open to relieve pressure and ensure the safe operation of the device.

[0022] The lower end of the transmission main shaft 4 is fixed with a stirring blade 11 to improve the stirring effect. The stirring blade 11 is spiral in shape and is located directly above the discharge port 9. It can stir the material in the discharge port 9, avoid the presence of stirring dead corners in the discharge port 9, and ensure that the material is mixed evenly.

[0023] Specifically, when using this building environmentally friendly thermal insulation material mixing and stirring device, environmentally friendly thermal insulation materials of different components are added through the feed inlet 8 at the top of the mixing tank 1 according to the preset ratio, and the feed inlet 8 cover is closed after feeding is completed. Start the drive motor 3, which drives the transmission shaft 4 to rotate, thereby driving the mixing rack 5 and the cleaning components to operate synchronously: the main mixing rod 51 pushes the material in a circular motion along the radial direction, the auxiliary mixing rod 52 is tilted at 45° to shear and tumble the material, and the dispersion hole 53 guides some material through the rod to form convection, breaking the material vortex and fiber agglomeration, and achieving uniform mixing; at the same time, the annular cleaning rack 6 drives the elastic scraper 7 to rotate against the inner wall of the box, removing the material attached to the inner wall in real time to avoid residue; During the mixing process, the second mixing blade 12 follows the annular cleaning frame 6 to carry out the mixing work, increasing the mixing effect of the device. At the same time, the synchronous rotation of the first mixing blade 11 at the lower end of the drive shaft 4 stirs the material at the discharge port 9, effectively preventing the material from settling in the discharge port 9 and forming dead corners, ensuring that the material is mixed evenly. The mixing state of the materials in the chamber can be observed in real time through the observation window. If uneven mixing is found, such as fiber agglomeration, the stirring speed can be adjusted or the stirring time can be extended. If the pressure in the chamber rises abnormally, such as due to exothermic reaction of the materials, the pressure valve will automatically open to release pressure and ensure the safety of the device. Once the materials are mixed to the preset requirements, the electrically controlled valve is opened, and the mixed environmentally friendly insulation material is discharged from the discharge port 9 and enters the subsequent construction stage. During the discharge process, the drive motor 3 can continuously drive the transmission shaft 4 to rotate, the stirring blades 11 can accelerate the discharge rate, and the cleaning components can further remove the residue on the inner wall of the box to prepare for the next mixing.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
