Description

Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to a homogenization device for premixed concrete admixtures. Background Technology

[0002] With the continuous advancement of science and technology, the requirements for various properties of building materials such as concrete, especially durability, are becoming increasingly stringent. Currently, most engineering construction projects in my country use ready-mixed concrete, and one of the effective methods to improve its performance is to add admixtures to replace part of the cement. In the past, only a single type of admixture was used, but now two or more admixtures are often used to complement each other, further improving the performance of concrete and extending its service life.

[0003] A search revealed that Chinese utility model patent CN211250805U discloses a premixed concrete admixture homogenization device, comprising a base and a conveyor belt. A mixing tank is fixedly connected to the upper surface of the base, and a machine box is fixedly connected to the upper surface of the mixing tank. A first motor is fixedly connected inside the machine box, and a first bearing passes through the surface of the mixing tank. The output shaft of the first motor passes through the first bearing. This device achieves the mixing of concrete inside the mixing tank through the rotation of a hollow shaft. However, in actual use, the concrete tends to stick to the inner wall of the mixing tank, requiring manual cleaning. Generally, the device needs to be stopped and cleaned after each homogenization of the concrete admixture, resulting in low homogenization efficiency. Utility Model Content

There is a stabilizing block 14, with two rotating through holes at its top. A stirring rod 15 is rotatably connected inside each of the two rotating through holes.

A circular rack 18 is fixedly connected inside the stirring opening. The rotating gear 17 meshes with the circular rack 18. After the concrete raw materials are poured into the mixing tank 2, the electric telescopic rod 7 will drive the stirring plate 9 closer to the mixing tank. After mixing tank 2, once the mixing block 16 and mixing rod 15 have entered the interior of mixing tank 2, the output end of the second motor 11 will drive the stabilizing block 14 to rotate, and drive multiple mixing rods 15 to rotate around the second motor 11. During the rotation of the mixing rods 15, the rotating gear 17 meshes with the ring rack 18, causing the mixing rods 15 to rotate around themselves. The mixing block 16 then thoroughly mixes the concrete inside the mixing tank 2.

[0026] Please see Figure 1 , Figure 4 and Figure 6Another connecting block 8 has a cleaning plate 10 fixedly connected to one end. The top of the cleaning plate 10 has a cleaning opening. An inner wall cleaning mechanism is fixedly installed inside the cleaning opening. The inner wall cleaning mechanism includes a third motor 19. Four support rods 20 are fixedly connected to the top of the cleaning plate 10. A fixing plate 21 is fixedly connected between the tops of the four support rods 20. The top of the fixing plate 21 is fixedly connected to one end of the third motor 19. The output end of the third motor 19 extends to the bottom end of the fixing plate 21 and is fixedly connected to a cleaning block 22. The outer wall of the cleaning block 22 is rotatably connected to the inside of the cleaning opening. A cleaning sleeve 23 is fixedly connected to the bottom end of the cleaning block 22. A cleaning brush 24 is fixedly connected to the outer wall of the cleaning sleeve 23. A cleaning rod 31 is fixedly connected to the bottom end of the cleaning block 22. A cleaning brush 24 is fixedly connected to the outer wall of the cleaning rod 31. A transmission sleeve 32 is fixedly connected, and a scraper 33 is fixedly connected to the outer wall of the transmission sleeve 32. When the electric telescopic rod 7 is activated, the stirring plate 9 is driven away from the mixing box 2. When the first motor 5 is powered on, the output end of the first motor 5 drives the transmission gear 6 to rotate. Through the meshing of the gear, the rotating block 4 is driven to rotate until the cleaning plate 10 approaches the mixing box 2. With the cooperation of the third motor 19, the cleaning block 22, the cleaning sleeve 23 and the cleaning brush 24, it contacts the inner wall of the mixing box 2 and rotates to carry out a thorough cleaning of the inside of the mixing box 2. This improves the convenience of cleaning the inner wall of the mixing box 2.

After the concrete passes through the interior of the mixing tank 2, it is conveyed to the interior of the discharge opening. When the fourth motor 27 is powered on, the output end of the fourth motor 27 drives the conveying shaft 28 to rotate and drives the conveying auger 29 to convey the concrete inside the conveying cylinder 25.

[0028] Please see Figure 1 Stable feet 34 are fixedly connected to the four corners of the bottom of the support plate 1 to support the position of the overall device and increase the height of the overall device.

[0029] In summary, when using this ready-mixed concrete admixture homogenization device, the concrete raw materials are first poured into the mixing tank 2. Then, with the activation of the electric telescopic rod 7, the mixing plate 9 is moved closer to the mixing tank 2 until the mixing block 16 and mixing rod 15 extend into the mixing tank 2. After the second motor 11 is energized, its output drives the stabilizing block 14 to rotate, causing multiple mixing rods 15 to rotate around the second motor 11. During the rotation of the mixing rods 15, the meshing of the rotating gear 17 and the ring rack 18 causes the mixing rods 15 to rotate around themselves. This, along with the mixing block 16, causes the mixing tank 2 to rotate. The concrete inside is thoroughly mixed. When the electric telescopic rod 7 is activated, the mixing plate 9 is moved away from the mixing tank 2. Then, when the first motor 5 is energized, its output drives the transmission gear 6 to rotate. Through the meshing of the gear, the rotating block 4 rotates until the cleaning plate 10 approaches the mixing tank 2. Then, when the third motor 19 is energized, its output drives the cleaning block 22 to rotate. This causes the cleaning sleeve 23 and the cleaning brush 24 to contact the inner wall of the mixing tank 2. Through rotation, the interior of the mixing tank 2 is thoroughly cleaned, improving the convenience of cleaning the inner wall of the mixing tank 2.
