Description

Technical Field

[0001] This utility model relates to the field of mortar mixing technology, and in particular to a green building environmentally friendly mortar mixing device. Background Technology

[0002] Green building environmentally friendly mortar is a new type of gel material adapted to modern green building concepts. Its raw materials use industrial solid waste, such as fly ash, slag ash, and recycled fine aggregates from construction waste, to replace some of the traditional cement and natural sand. This reduces resource extraction and solid waste accumulation pollution, and also lowers carbon emissions during the production process. The production of green building environmentally friendly mortar requires the use of mixing equipment to blend and stir the cement, sand, and industrial solid waste.

[0003] Existing mortar mixing equipment typically involves directly pouring various dry raw materials into a mixing tank and adding water. Then, a motor-driven agitator is used to mix the raw materials. Unmixed raw materials are prone to forming clumps when mixed with water, which prevents the raw materials from being evenly distributed in the mortar. This prolongs the mixing time and reduces the mixing efficiency of the mortar.

[0004] Therefore, it is necessary to develop a green building environmentally friendly mortar mixing device to address the above-mentioned shortcomings. Utility Model Content

[0022] It is understood that all electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned in this article are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices. Therefore, this utility model will not explain the control method and circuit connection in detail. At the same time, all parts not described in detail in this utility model are common technologies known to those skilled in the art.

[0023] In one specific embodiment of this utility model, such as Figure 1As shown, the system includes a mixing tank 1 and a premixing chamber 2. The top of the mixing tank 1 is fixedly connected to a tank cover 3, and the side wall is fixed and connected to a water inlet 7. The premixing chamber 2 is fixedly connected to the top surface of the tank cover 3. Several feed hoppers 4 are fixedly connected to the top surface of the premixing chamber 2. A motor 5 is fixedly connected to the middle position of the top surface of the premixing chamber 2. A rotating shaft 6 is coaxially fixedly connected to the output end of the motor 5. The rotating shaft 6 passes through the premixing chamber 2 and the tank cover 3 and extends into the bottom of the inner cavity of the mixing tank 1. A first stirring component is provided in the premixing chamber 2, and a second stirring component is provided in the mixing tank 1.

[0024] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the first mixing assembly includes several first mixing rods 8, which are fixedly connected at intervals to the outer wall of the rotating shaft 6. The rotating shaft 6 is driven to rotate by the motor 5, causing the first mixing rods 8 to rotate in the premixing chamber 2, which disperses and initially mixes the dry raw materials fed from different feed hoppers 4, avoiding the accumulation of single raw materials and affecting subsequent mixing with water.

[0025] Specifically, the inner wall of the bottom surface of the premixing chamber 2 is a conical structure with a discharge port 9 in the middle. A discharge cylinder 10 is fixed and connected to the discharge port 9, and the bottom end of the discharge cylinder 10 extends into the inner cavity of the mixing tank 1. The first stirring rod 8 located at the bottom of the premixing chamber 2 is fixedly connected to a first scraper 11 at the end away from the rotating shaft 6. The first scraper 11 is in contact with the bottom surface of the premixing chamber 2. The rotation of the rotating shaft 6 drives the first scraper 11 to rotate, scraping off the raw materials remaining on the bottom surface of the premixing chamber 2.

[0026] Specifically, an auger 12 is installed inside the discharge cylinder 10. The auger 12 is fixedly sleeved on the outer wall of the rotating shaft 6 and has a gap between it and the inner wall of the discharge cylinder 10. When the rotating shaft 6 rotates, the auger 12 rotates synchronously, conveying the dry raw materials falling from the premixing chamber 2 into the mixing tank 1, avoiding local accumulation of raw materials due to concentrated gravity falling. At the same time, the auger 12 can further break up any lumps that may exist in the raw materials, improving the premixing effect.

[0027] Specifically, a trumpet-shaped distributing cylinder 13 is fixedly sleeved on the outer wall of the rotating shaft 6 below the discharge cylinder 10. Several strip-shaped discharge holes 14 are opened through the outer wall of the distributing cylinder 13. After the dry raw materials conveyed by the auger 12 fall into the distributing cylinder 13, they generate centrifugal force as the rotating shaft 6 rotates, and are scattered into the mixing tank 1 through the discharge holes 14 and the end of the powder cylinder 13, further dispersing the raw materials in the mixing tank 1 and avoiding the agglomeration of single raw materials or the agglomeration of the mixture in the middle of the mixing tank 1.

[0028] Specifically, a fixing rod 15 is fixedly connected to the inner wall of the mixing tank 1, and a second scraper 16 is fixedly connected to the top of the fixing rod 15. The second scraper 16 is in contact with the outer wall of the distributing cylinder 13. When the distributing cylinder 13 rotates, the second scraper 16 can scrape off the dry raw materials adhering to its outer wall.

[0029] In one specific embodiment of this utility model, such as Figure 1 As shown, the second stirring assembly includes several second stirring rods 17, which are fixedly connected at intervals to the outer wall of the rotating shaft 6. A third scraper 18 is fixedly connected to one end of each second stirring rod 17 near the inner wall of the mixing tank 1, and the third scraper 18 is in contact with the inner wall of the mixing tank 1. When the rotating shaft 6 drives the second stirring rods 17 to rotate, the dry raw materials and water are thoroughly stirred and mixed. At the same time, the third scraper 18 can scrape off the mortar remaining on the tank wall, preventing lumps from accumulating and affecting the mixing efficiency, and ensuring the cleanliness of the tank wall.

[0030] Specifically, the bottom of the mixing tank 1 has a conical structure with a discharge port 19 in the middle. A valve is installed at the discharge port 19 to facilitate the discharge of mortar after mixing. A third stirring rod 20 is fixedly connected to the outer wall of the bottom end of the rotating shaft 6, and a fourth scraper 21 is fixedly connected to the top of the third stirring rod 20. The fourth scraper 21 is in contact with the bottom surface of the mixing tank 1. During the mixing process, the fourth scraper 21 rotates with the rotating shaft 6 and can scrape off the raw materials or mortar deposited at the bottom of the tank.

[0031] In one specific embodiment of this utility model, such as Figure 1 As shown, a support rod 22 is fixedly connected to the inner wall of the top of the mixing tank 1. A bearing hole adapted to the rotating shaft 6 is opened at the center of the support rod 22. The bottom of the rotating shaft 6 passes through the bearing hole and is rotatably connected to it. The support rod 22 provides bottom support for the rotating shaft 6, preventing the rotating shaft 6 from shaking or bending due to excessive length or load, ensuring stable rotation of the first and second stirring components, improving stirring accuracy and extending the service life of the device.

[0032] Working principle of this utility model: When using this utility model, cement, sand, and industrial solid waste are fed into the premixing chamber 2 from the feed hopper 4. The motor 5 is started, driving the rotating shaft 6 to rotate. The first stirring rod 8 disperses and initially mixes the raw materials. The premixed material converges along the conical surface to the discharge port 9. After entering the discharge cylinder 10, the auger 12 on the rotating shaft 6 evenly conveys the premixed material to the distribution cylinder 13. The centrifugal force generated by the rotation of the distribution cylinder 13 causes the premixed material to be discharged into the mixing tank 1 through the discharge hole 14. An appropriate amount of water is injected into the mixing tank 1 through the water inlet 7. The second stirring rod 17 stirs the dispersed premixed material and water. The third scraper 18 removes residue from the tank wall, and the third stirring rod 20 and the fourth scraper 21 prevent sedimentation at the bottom of the tank. After mixing is complete, the valve of the discharge port 19 at the bottom of the mixing tank 1 is opened to discharge the mortar.
