Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mixing mechanisms, specifically a mixing mechanism for low-carbon cementitious materials. Background Technology
[0002] Low-carbon cementitious materials are a new type of building material prepared by physical activation or chemical stimulation using industrial solid waste (such as fly ash, slag, red mud, etc.) as the main raw materials. They are characterized by low energy consumption, low emissions, low cost, and excellent durability. Their core components include calcium oxide, silicon dioxide, aluminum oxide, and trace metal elements. Performance is optimized by adjusting the raw material ratio (such as limestone, perlite, attapulgite). The mixing process is crucial in the preparation and construction process. Through physical mixing, chemical activation, and performance optimization, low-carbon cementitious materials can be efficiently applied in fields such as building engineering (such as ready-mixed concrete and bridge construction), environmental protection engineering (such as heavy metal solidification), and road and water conservancy, thus promoting green building and sustainable development.
[0003] Existing low-carbon cementitious material mixing mechanisms often suffer from incomplete mixing of cementitious material particles and residual paste-like mixtures due to the material's inherent viscosity. These adhered substances are tightly bonded to the wall surface. Because cementitious materials have a certain setting property, they gradually harden over time, making cleaning extremely difficult. Workers must spend considerable time and effort repeatedly scraping and rinsing with specialized tools to remove them, increasing labor costs. Furthermore, some hardened or difficult-to-remove material is forcibly scraped off and discarded during cleaning, resulting in unnecessary waste of raw materials. Frequent and forceful cleaning can also cause wear and tear on the inner wall of the mixing mechanism, affecting its subsequent mixing efficiency and service life. Therefore, we propose a new low-carbon cementitious material mixing mechanism. Utility Model Content
[0004] The purpose of this invention is to provide a low-carbon cementitious material mixing mechanism to solve the problem mentioned in the background art: when existing low-carbon cementitious material mixing mechanisms are used, some cementitious material particles that are not completely mixed evenly adhere to their inner walls, as well as a paste-like mixture remaining due to the material's own viscosity. These adhered substances are tightly stuck to the wall surface. Because cementitious materials have certain solidification characteristics, they gradually harden over time, making cleaning extremely difficult. Workers need to spend a lot of time and energy, using specialized tools to repeatedly scrape and rinse to remove them. This not only increases additional labor costs, but also causes unnecessary waste of raw materials because some hardened or difficult-to-remove materials are forcibly scraped off and discarded during the cleaning process. At the same time, frequent and forceful cleaning may also cause wear to the inner wall of the mixing mechanism, affecting its subsequent mixing effect and service life.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-carbon cementitious material mixing mechanism, comprising an outer frame, a mixing tank centrally located within the outer frame, a vertical rod centrally located within the mixing tank, a mixing paddle fixedly mounted on the surface of the vertical rod, a first motor centrally located at the top of the outer frame, an upper groove centrally located at the top of the mixing tank, lower connecting plates fixedly connected to the bottom positions of both sides of the outer frame's outer wall, a second motor fixedly mounted on the top of each of the two lower connecting plates, cams centrally located at the front ends of each of the two second motors, rolling grooves centrally located on the outer walls of each of the two cams, connectors centrally located at the upper ends of each of the two cams, rolling balls rotatably mounted on the lower ends of each of the two connectors, guide rods fixedly connected to the center of the top of each of the two connectors, guide plates fixedly connected to the top positions of both sides of the outer frame's outer wall, side grooves centrally located on both sides of the outer frame's outer wall, fixing plates fixedly connected to the center positions of the surfaces of the two guide rods, a first spring sleeved on the top positions of the surfaces of the two guide rods, and second springs fixedly connected to the four corner positions of the top and bottom of the mixing tank.
[0006] Compared with the prior art, the beneficial effects of this utility model are:
[0007] This low-carbon cementitious material mixing mechanism, through the design of an outer frame, a second motor, a guide plate, a fixed plate, a guide rod, a first spring, a second spring, a connector, rolling balls, a cam, and a rolling groove, utilizes the design of the second motor to drive the cam to rotate. The low-friction rolling of the rolling balls within the rolling groove converts the rotational motion into vertical reciprocating vibration of the guide rod. The vibration energy is transmitted to the mixing tank via the fixed plate and the first spring. Combined with the elastic support of the second spring, this causes micro-vibrations in the inner wall and side grooves of the mixing tank. This design effectively disrupts the adhesion between the cementitious material and the inner wall of the tank, causing material not carried by the mixing paddle to automatically detach under the vibration, preventing stubborn residues in dead zones. Simultaneously, the vibration energy acts directly on the entire mixing tank, ensuring sufficient vibration of the inlet and outlet pipes, preventing blockage of the pipes. Replacing manual cleaning with physical vibration not only reduces material waste but also simplifies subsequent maintenance processes, shortens the cleaning time after each mixing cycle, and significantly improves production efficiency, meeting the high-efficiency and environmentally friendly application requirements of low-carbon cementitious materials.

Detailed Implementation
[0014] 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.
[0015] Please see Figure 1-5 This utility model provides a technical solution: a low-carbon cementitious material mixing mechanism, including an outer frame 1, a mixing tank 2 centrally located within the outer frame 1, a vertical rod 3 centrally located within the mixing tank 2, a mixing paddle 4 fixedly mounted on the surface of the vertical rod 3, a first motor 5 centrally located at the top of the outer frame 1, an upper groove 6 centrally located at the top of the mixing tank 2, lower connecting plates 7 fixedly connected to the bottom positions on both sides of the outer wall of the outer frame 1, a second motor 8 fixedly mounted on the top of each of the two lower connecting plates 7, a cam 18 centrally located at the front end of each of the two second motors 8, and an opening on the outer wall of each of the two cams 18. There is a rolling groove 19, and the upper end of each of the two cams 18 is provided with a connector 16. The lower end of each of the two connectors 16 is rolled with a ball bearing 17. The center of the top of each of the two connectors 16 is fixedly connected to a guide rod 11. The top positions of both sides of the outer wall of the outer frame 1 are fixedly connected to a guide plate 9. The center of both sides of the outer wall of the outer frame 1 is provided with a side groove 15. The center position of the surface of each of the two guide rods 11 is fixedly connected to a fixing plate 10. The top position of the surface of each of the two guide rods 11 is fitted with a first spring 12. The four corner positions of the top and bottom of the mixing tank 2 are fixedly connected to a second spring 13.
[0016] The No. 1 motor 5 is fixedly installed on the top of the outer frame 1 through the connecting bracket. The upper end of the vertical rod 3 extends through the outside of the upper groove 6, so that the mixing tank 2 will not be obstructed by the mixing mechanism when it moves up and down. The No. 1 motor 5 is fixedly connected to the No. 1 main shaft through its bottom output end. The bottom of the No. 1 main shaft extends through the inside of the outer frame 1 and is fixedly connected to the top of the vertical rod 3 through the coupling. The No. 1 motor 5 is connected to the vertical rod 3 through the coupling of the No. 1 main shaft, and the rotational torque is directly transmitted to the mixing paddle 4 to ensure mixing efficiency and material uniformity.
[0017] The second motor 8 is fixedly connected to the second spindle through the output end of its front surface. The front ends of the two second spindles are fixedly connected to the rear surfaces of the two cams 18 respectively. The second motor 8 drives the cams 18 to rotate. Through the contact between the contour of the cams 18 and the rolling ball 17, the rotational motion is converted into the vertical reciprocating motion of the guide rod 11, which in turn drives the mixing tank 2 to vibrate, thereby breaking the adhesion between the cementitious material and the inner wall and reducing residue.
[0018] Two fixed plates 10 extend through the outside of two side grooves 15 on opposite sides and are fixedly connected to the center of both sides of the mixing tank 2. A guide groove is provided on one side of the bottom of the guide plate 9. The upper end of the guide rod 11 extends through the outside of the guide groove, and the surface of the guide rod 11 slides in contact with the inner wall of the guide groove. The lower ends of two rolling balls 17 extend through the inside of two rolling grooves 19 and contact the bottom of the rolling grooves 19. The sliding contact between the guide groove of the guide plate 9 and the guide rod 11 ensures that the vibration is transmitted vertically. The fixed plate 10 directly applies the displacement of the guide rod 11 to the mixing tank 2. With the avoidance design of the side grooves 15, the vibration energy is efficiently applied to the mixing tank 2.
[0019] The top of spring 12 is fixedly connected to the bottom of guide plate 9, and the bottom of spring 12 is fixedly connected to the top of fixed plate 10. The upper and lower ends of the eight springs 13 arranged vertically are fixedly connected to the inner wall of outer frame 1. Spring 12 provides elastic restoring force during the reciprocating motion of guide rod 11 to avoid mechanical hard collisions. Spring 13 connects mixing tank 2 and outer frame 1 to balance the vibration energy distribution, prevent equipment overload, and assist mixing tank 2 to quickly return to its initial position, ensuring that the vibration frequency is controllable.
[0020] A feed pipe 21 and a discharge pipe 20 are fixedly connected to the top and bottom center of one side of the mixing tank 2, respectively. A pipe groove 14 is opened at the bottom center and the top of one side of the outer frame 1. One end of the feed pipe 21 and the discharge pipe 20 respectively extends to the outside of the two pipe grooves 14. The raw material is fed into the mixing tank 2 through the feed pipe 21. After the mixing is completed, the discharge operation is performed by opening the valve on the discharge pipe 20. The pipe groove 14 is used to provide a certain amount of movement space for the mixing tank 2 when it vibrates up and down.
[0021] Support legs are fixedly connected to the front and rear ends of the bottom of the two lower connecting plates 7, and stabilizing plates are fixedly connected to the bottom of the four support legs, which play a role in stabilizing the overall equipment.
[0022] Motor 5 drives the vertical rod 3 to rotate via the main shaft, which in turn drives the stirring paddle 4 to rotate inside the mixing tank 2 to mix the cementitious material. The upper end of the vertical rod 3 passes through the upper groove 6 at the top of the mixing tank 2 to ensure that the mixing tank 2 will not interfere with the transmission system during subsequent vibration. At this time, two motors 8 drive two cams 18 to rotate synchronously via the main shaft. The rolling groove 19 on the outer wall of the cam 18 forms a low-friction rolling contact with the rolling ball 17 at the lower end of the connector 16, converting the rotational motion of the cam 18 into the vertical reciprocating motion of the guide rod 11. The guide rod 11 slides along the guide groove of the guide plate 9, and transmits the vibration energy to the mixing tank 2 through the fixing plate 10, causing it to vibrate slightly. The first spring 12 provides elastic restoring force during the movement of the guide rod 11 to avoid mechanical hard collisions. The eight second springs 13 connected to the inner wall of the outer frame 1 at the four corners of the mixing tank 2 balance the distribution of vibration energy, prevent equipment overload, and at the same time assist the mixing tank 2 in quickly returning to its initial position, ensuring that the vibration frequency is controllable. The raw material is input into the mixing tank 2 through the feed pipe 21. After mixing is completed, the discharge pipe 20 valve is opened to discharge the material. The pipe groove 14 provides movement clearance space for the feed pipe 21 and the discharge pipe 20, and in conjunction with the vibration of the mixing tank 2, reduces the amount of slurry residue at pipe bends and on the inner wall of the tank.
[0023] In summary, this low-carbon cementitious material mixing mechanism, through the design of the outer frame 1, a second motor 8, a guide plate 9, a fixed plate 10, a guide rod 11, a first spring 12, a second spring 13, a connector 16, rolling balls 17, a cam 18, and a rolling groove 19, allows the second motor 8 to drive the cam 18 to rotate. The low-friction rolling of the rolling balls 17 within the rolling groove 19 converts the rotational motion into vertical reciprocating vibration of the guide rod 11. The vibration energy is transmitted to the mixing tank 2 via the fixed plate 10 and the first spring 12. Combined with the elastic support of the second spring 13, this causes slight vibrations in the inner wall and side grooves 15 of the mixing tank 2. This design effectively disrupts the adhesion between the cementitious material and the inner wall of the tank, causing materials not driven by the mixing paddle 4 to automatically detach under vibration, preventing stubborn residues in dead zones. Simultaneously, the vibration energy directly acts on the entire mixing tank 2, ensuring that the feed pipe 21 and the discharge pipe 20 also receive sufficient vibration, preventing blockage of the pipes by the slurry. Replacing manual cleaning with physical vibration not only reduces material waste but also simplifies subsequent maintenance processes, shortens cleaning time after each mixing cycle, and significantly improves production efficiency, meeting the application requirements of low-carbon cementitious materials for high efficiency and environmental protection.
