Description

Technical Field

[0001] This utility model relates to the field of cement processing technology, and in particular to a multifunctional mixing device for cement processing. Background Technology

[0002] Cement, as a widely used building material, is mainly used to make concrete, mortar, and certain types of composite materials. In the cement processing, raw materials such as limestone, clay, and iron ore need to be calcined at high temperatures to form clinker. The clinker is then mixed with an appropriate amount of gypsum and ground into fine powder. Existing mixing and stirring devices still rely on a single stirring mode, which makes it difficult to meet the synergistic requirements of high-speed dispersion and low-speed homogenization. The actual mixing uniformity is limited. At the same time, although the existing mixing rack is equipped with scraper blades to scrape off the residues adhering to the inner wall of the mixing tank, the scraper blades themselves have a certain degree of extension, which causes some material to stick to the scraper blades, affecting the scraping effect and resulting in material waste.

[0003] To address the aforementioned issues, a multifunctional mixing device for cement processing has been developed. Utility Model Content

[0004] To overcome the shortcomings of existing mixing devices that struggle to simultaneously meet the demands of high-speed dispersion and low-speed homogenization, resulting in limited actual mixing uniformity, and the fact that while existing mixing racks are equipped with scraping blades to remove residues adhering to the inner wall of the mixing drum, the scraping blades themselves have a certain degree of extension, causing some material to stick to the scraping blades, affecting the scraping effect and leading to material waste, this utility model provides a multifunctional mixing device for cement processing.

[0005] The technical implementation scheme of this utility model is as follows: a multifunctional mixing device for cement processing includes a mixing drum, a feed inlet on the upper left side of the mixing drum, a mounting base connected to the upper middle part of the mixing drum, a drive motor mounted on the mounting base, a centrifugal stirring frame connected to the output shaft of the drive motor, a stirring assembly rotatably connected to the mixing drum, the stirring assembly rotating at a speed lower than the centrifugal stirring frame, a rotating shaft rotatably connected to the upper part of the mixing drum, a pulley assembly provided between the upper part of the rotating shaft and the output shaft of the drive motor, a first gear connected to the rotating shaft, a second gear connected to the upper part of the stirring assembly, the second gear meshing with the first gear, a lifting component slidably connected to the lower part of the mixing drum, a locking component engaging the lifting component and the mixing drum, a mounting frame connected to the lower part of the mixing drum, a striking component slidably connected to the mounting frame, a spring connecting the striking component and the mounting frame, a drive motor mounted on the mounting frame, a cam connected to the output shaft of the drive motor, the cam contacting the striking component.

[0006] Furthermore, the stirring assembly is connected to four sets of stirring blades and two sets of scrapers. The scrapers can scrape off the material remaining on the inner wall of the mixing tank, and all the scrapers are arc-shaped structures that fit the inner wall of the mixing tank.

[0007] Furthermore, the second gear has a larger specification than the first gear.

[0008] Furthermore, the upper part of the lifting component has an inclined structure.

[0009] Furthermore, the card has an assistive component on its right side.

[0010] Furthermore, the left side of the striking component has a spherical structure.

[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes the combined action of a centrifugal mixing rack and a mixing component to create a strong centrifugal force field and a slow shearing effect, enabling rapid mixing of materials, preventing material clumping, and effectively improving mixing uniformity. Furthermore, the scraper on the mixing component can dynamically adhere to the inner wall of the mixing tank, scraping away adhering materials in real time, reducing the frequency of manual cleaning and minimizing material waste. Simultaneously, the impact component generates high-frequency pulse vibration through the interaction of a cam and a spring, effectively disrupting the electrostatic adsorption and mechanical interlocking between cement particles, preventing blockages during unloading, and thus ensuring smooth unloading.

Detailed Implementation

[0019] 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.

[0020] A multifunctional mixing device for cement processing, such as Figures 1-5 As shown, the system includes a mixing tank 1 with a feed inlet on the upper left side. A mounting base 2 is connected to the upper middle part of the mixing tank 1, and a drive motor 3 is mounted on the mounting base 2. A centrifugal stirring frame 4 is connected to the output shaft of the drive motor 3. A stirring assembly 5 is rotatably connected to the mixing tank 1. The stirring assembly 5 rotates at a speed lower than that of the centrifugal stirring frame 4. The stirring assembly 5 has four sets of stirring blades and two sets of scrapers. The scrapers can remove residual material from the inner wall of the mixing tank 1. All scrapers are arc-shaped structures that conform to the inner wall of the mixing tank 1. A rotating shaft 6 is rotatably connected to the upper part of the mixing tank 1. A pulley assembly 7 is provided between the upper part of the rotating shaft 6 and the output shaft of the drive motor 3. A first gear 8 is connected to the rotating shaft 6. The upper part of the mixing tank 1 is connected to a second gear 9, which meshes with the first gear 8. The second gear 9 is larger than the first gear 8. The lower part of the mixing tank 1 is slidably connected to a lifting component 10. The upper part of the lifting component 10 is a sloping structure. A locking component 11 is engaged between the lifting component 10 and the mixing tank 1. A booster is provided on the right side of the locking component 11. The lower part of the mixing tank 1 is connected to a mounting frame 12. A striking component 13 is slidably connected to the mounting frame 12. The left side of the striking component 13 is a spherical structure. A spring 14 is connected between the striking component 13 and the mounting frame 12. A drive motor 15 is mounted on the mounting frame 12. A cam 16 is connected to the output shaft of the drive motor 15. The cam 16 is in contact with the striking component 13.

[0021] It should be noted that cement is a widely used building material, mainly used to make concrete, mortar, and certain types of composite materials. In the cement processing, raw materials such as limestone, clay, and iron ore are calcined at high temperatures to form clinker. The clinker is then mixed with an appropriate amount of gypsum and ground into a fine powder. This device can improve the material mixing effect, making the mixture more uniform. First, materials are sequentially injected into the mixing tank 1 through the feed inlet. Then, the drive motor 3 is started, driving the pulley assembly 7 to rotate, causing the shaft 6 to rotate, which in turn causes the first gear 8 and the second gear 9 to rotate successively, thereby driving the mixing assembly 5 to rotate. The mixing assembly 5 moves the upper layer of materials. The four sets of mixing blades on the mixing assembly 5 perform slow shearing and tumbling of the materials, ensuring uniform distribution of the fine powder. Two sets of scrapers rotate close to the inner wall of the mixing tank 1, scraping off adhering materials in real time to prevent clumping and affecting the uniformity of mixing. At the same time, the drive motor 3 directly drives the centrifugal mixing frame 4 to rotate at high speed, thereby generating a strong centrifugal force field to mix the materials... The material at the bottom of barrel 1 is rapidly thrown against the inner wall of mixing barrel 1, forming a vortex motion, which in turn allows the material at the top and bottom to be fully mixed. The mixed material will move downward with the inclined structure at the bottom of mixing barrel 1, and the mixing operation will be repeated to make the mixing more uniform. After the mixing is completed, the operator locks the lifting component 10 by contacting the locking component 11 with the auxiliary component. The mixed material will be discharged from the bottom of mixing barrel 1, completing the discharge. To avoid blockage, the drive motor 15 can be started. The output shaft of the drive motor 15 rotates, driving the cam 16 to rotate. The cam 16 will intermittently contact the striking component 13. When the outward protrusion of the cam 16 contacts the striking component 13, it will drive the striking component 13 to move to the right. At this time, the spring 14 is compressed. When the cam 16 does not contact the striking component 13, the striking component 13 will return to the left under the reaction force of the spring 14. During this process, the striking component 13 will intermittently contact the mixing barrel 1, breaking the electrostatic adsorption and mechanical interlocking between the materials, preventing blockage during unloading, and thus ensuring smooth unloading.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
