Description

Technical Field

[0001] This utility model relates to the field of admixture device technology, specifically to an admixture device for concrete water-reducing agents. Background Technology

[0002] A mixing device is a piece of equipment used to mix different substances together, commonly found in industrial production. For example, in concrete production, a mixing device can be used to mix cement, sand, water, and other additives together to make concrete.

[0003] Common mixing devices typically use a mixing tank to mix concrete raw materials and water-reducing agents together. A motor provides power to drive components such as a drive shaft and a mixing rod. The mixing rod stirs the concrete raw materials and water-reducing agents in the mixing tank to ensure thorough mixing.

[0004] However, when mixing concrete raw materials with water-reducing agents, water-reducing agents need to be added during the mixing of concrete raw materials. During the concrete mixing process, due to the mechanical mixing action, the water-reducing agent may be drawn into the agglomerates of cement particles, making it difficult to distribute evenly in the concrete raw materials. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mixing device for concrete water-reducing agents, thereby solving the problem mentioned in the background art that when concrete raw materials are mixed with water-reducing agents, water-reducing agents need to be added during the mixing of concrete raw materials. However, during the concrete mixing process, due to the mechanical stirring action, the water-reducing agent may be entrained into the agglomerates of cement particles, making it difficult to distribute evenly in the concrete raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for concrete water-reducing agents, comprising:

Figure 3 The outlet of water tank 11 is equipped with a water pipe 12. Please refer to [link / reference]. Figure 2 A fixing bracket 13 is installed in the middle of the upper surface of the mounting bracket 2, and a hydraulic telescopic rod 14 is installed at the bottom of the fixing bracket 13. Please refer to [link / reference]. Figure 3 A water delivery plate 15 is installed at the bottom end of the hydraulic telescopic rod 14. The water pipe 12 communicates with the inner cavity of the water delivery plate 15. Please refer to [link / reference]. Figure 5 Spray nozzles 16 are evenly distributed at the bottom of the water conveying plate 15;

[0028] Please see Figure 4 Mounting plate 17 is set on the upper surface of conveying pipe 8. Connection holes 18 are opened on the upper surface of mounting plate 17 and the corresponding position of nozzle 16. Nozzle 16 is inserted into the interior of connection hole 18. Feed pipe 19 is installed at the bottom of mixing box 3.

[0029] The starting motor 10 drives the auger 9 to rotate, which in turn moves the concrete raw materials along the inside of the conveying pipe 8. The water-reducing agent is conveyed to the water conveying plate 15 through the water pipe 12, and the hydraulic telescopic rod 14 pulls out the nozzle 16 to clean the outlet of the nozzle 16 and prevent it from being blocked. This allows the nozzle 16 to spray the water-reducing agent into the conveying pipe 8.

The stirring rod 6 further mixes the concrete raw materials and the water-reducing agent, effectively preventing the water-reducing agent from being entrained in the cement particle agglomerates. The water-reducing agent is evenly distributed in the concrete raw materials.

[0032] Please see Figure 4 A connecting plate 22 is installed on the inner wall of the mounting frame 2, and a connecting bracket 23 is installed on the surface of the connecting plate 22. The connecting bracket 23 is connected to the bottom of the conveying pipe 8, so that the conveying pipe 8 can be stably installed on the surface of the mounting frame 2.

[0033] Please see Figure 5 All surfaces of the nozzle 16 are fitted with sealing rings 24. Please refer to [link / reference].

[0034] Please see Figure 3 A water pump 26 is installed at the outlet of the water tank 11. The water pump 26 is connected to the inlet of the water pipe 12. Starting the water pump 26 can draw the water-reducing agent from the water tank 11 and inject it into the water delivery plate 15 through the water pipe 12.

[0035] The working process of this device is as follows: First, concrete raw materials are placed into the lower hopper 7. The motor 10 is started to drive the auger 9 to rotate. The auger 9 drives the concrete raw materials to move along the inside of the conveying pipe 8. Then, the water pump 26 is started to draw water-reducing agent from the water tank 11 and inject it into the water conveying plate 15 through the water pipe 12. The water-reducing agent is sprayed into the conveying pipe 8 through the nozzle 16. The auger 9 is used to fully mix the concrete raw materials and water-reducing agent, and then the mixture is conveyed to the mixing box 3. Finally, the motor 4 is started to drive the auger 9 to rotate. Rotating rod 5 drives the mixing rod 6 to rotate, which in turn mixes the concrete raw materials and water-reducing agent again. This effectively prevents the water-reducing agent from being incorporated into the cement particle agglomerates, ensuring that the water-reducing agent is evenly distributed in the concrete raw materials. Finally, activating the hydraulic telescopic rod 14 pulls out the nozzle 16 to clean its outlet and prevent it from becoming clogged. After cleaning the nozzle 16, the hydraulic telescopic rod 14 is activated again to insert the nozzle 16 into the connecting hole 18.
