Technical Field

[0001] This utility model belongs to the field of water-reducing agent production technology, specifically a water-reducing agent production and addition device. Background Technology

[0002] Water-reducing agents are one of the most important chemical additives in concrete admixtures. Their main function is to significantly reduce the amount of mixing water while maintaining the workability of concrete (such as slump), thereby improving the strength, durability, and workability of concrete. With the development of modern construction technology towards high-performance concrete (HPC) and ultra-high-performance concrete (UHPC), the research and application of water-reducing agents has become one of the core topics in concrete materials science.

Agglomeration areas will cause uneven dispersion of cement particles and obvious gradients in the distribution of hydration products.

[0004] Therefore, this utility model provides a water-reducing agent production and addition device. Utility Model Content

A slidable screening box 12 is connected to the upper part of the housing 4. The screening box 12 is located below a pair of material troughs 7. A transmission component is provided inside the housing 4. The transmission component is used to drive the baffle 9. During operation, by setting the base 1, a mixing tank 3 and a detachable housing 4 are set on the top of the base 1. The operator can pour the water-reducing agent raw material into the inclined material trough 7. The raw material automatically slides down to the feed port 8 due to gravity. The baffle 9 is controlled to open and close by the transmission component to realize quantitative feeding and avoid excessive material entering, which will cause material accumulation and make it difficult to screen and mix. The material falls into the screening box 12 through the feed port 8 to screen out lumps or impurities. The housing 4 is detachable to facilitate cleaning of residual particles in the screening box 12. The screened material enters the mixing tank 3 and is mixed evenly with other components.

[0024] The transmission assembly includes a ring 13 and a transmission unit; the ring 13 is slidably connected inside the housing 4; a pair of second connecting blocks 14 are fixedly connected to the inner circular wall of the ring 13; one side of each pair of second connecting blocks 14 is fixedly connected to the outside of the screening box 12; a set of support rods 15 are fixedly connected to the top of the ring 13; the top of each set of support rods 15 passes through a set of first connecting blocks 11 and is slidably connected inside the first connecting blocks 11; a pair of push rods 16 are fixedly connected inside the screening box 12; the pair of push rods 16 are respectively fixedly connected to the bottom of the baffle 9. During operation, by setting the ring 13 inside the housing 4 and allowing the ring 13 to slide inside the housing 4, the ring 13 can act as a transmission hub, driving the screening box 12 to move upward as a whole, causing the push rods 16 to push the baffle 9 upward, so that the material inside the trough 7 can fall downward into the screening box 12 for screening. The rigid connection between the push rods 16 and the baffle 9 allows the opening and closing of the discharge port 8 to be controlled synchronously when the screening box 12 is raised and lowered.

[0025] The transmission unit includes a rotating ring 17; the rotating ring 17 is rotatably connected inside the mixing tank 3; a set of connecting shafts 18 are fixedly connected to the outer circular wall of the rotating ring 17; one end of each set of connecting shafts 18 is fixedly connected to a connecting column 19; each set of connecting columns 19 is rotatably connected inside the mixing tank 3; a set of first protrusions 20 are fixedly connected to the bottom end of the ring 13; a set of second protrusions 21 are fixedly connected to the top end of each set of connecting columns 19; the second protrusions 21 are slidably connected to the bottom end of the first protrusions 20. During operation, by setting the rotating ring 17 rotatably connected inside the mixing tank 3, when the rotating ring 17 rotates, the connecting shafts 18 will drive the set of connecting columns 19 to rotate, causing the set of second protrusions 21 to contact the first protrusions 20. The ring 13 can act as a transmission hub to lift the ring 13, thereby driving the screening box 12 to complete the lifting and lowering movement, realizing the quantitative feeding of the equipment.

[0026] A cylinder 22 is fixedly connected to the bottom of the mixing tank 3; a motor 23 is fixedly connected to the top of the connecting plate 5; a first rotating rod 24 is provided at the output end of the motor 23; one end of the first rotating rod 24 passes through the inside of the mixing tank 3 and is rotatably connected to the top of the cylinder 22; the rotating ring 17 is fixedly connected to the first rotating rod 24. During operation, by setting the cylinder 22 inside the mixing tank 3 and fixing the motor 23 to the top of the connecting plate 5, when the motor 23 rotates, the rotating ring 17 will drive the connecting column 19 to rotate, so that the second protrusion 21 can lift the ring 13. When the connecting shaft 18 rotates, it can mix the raw materials inside the mixing tank 3.

[0027] A set of first connecting blocks 11 are respectively fixed to the bottom end of springs 25; the other end of each set of springs 25 is fixed to the top end of the ring 13. During operation, by fixing springs 25 to the bottom end of the first connecting blocks 11, after the motor 23 lifts the screening box 12 and then falls, the springs 25 can absorb the impact energy and increase the screening efficiency of the screening box 12.

[0028] The mixing tank 3 has a discharge port 26 at the bottom end, and the discharge port 26 passes through the base 1; a piston 27 is provided inside the discharge port 26. During operation, the mixed material can be discharged by opening the discharge port 26 at the bottom end of the mixing tank 3 and passing through the base 1.

[0029] Working Principle: A base 1 is installed, with a mixing tank 3 and a detachable housing 4 at its top. Workers can pour the water-reducing agent raw material into the inclined trough 7. The raw material automatically slides down to the discharge port 8 due to gravity. The baffle 9 is controlled to open and close via a transmission assembly, achieving quantitative feeding and preventing excessive material accumulation that would hinder screening and mixing. The material falls through the discharge port 8 into the screening box 12, where lumps or impurities are removed. The detachable housing 4 facilitates cleaning of residual particles within the screening box 12. The screened material enters the mixing tank 3 for uniform mixing with other components. A circular ring 13 is installed inside the housing 4, allowing it to slide within the housing. This ring acts as a transmission hub, driving the screening box 12 upwards. The push rod 16 then pushes the baffle 9 upwards, allowing the material in the trough 7 to fall into the screening box 12 for screening. The rigid connection between the push rod 16 and the baffle 9 ensures that the discharge port 8 opens and closes synchronously during the lifting and lowering of the screening box 12. By setting a rotating ring 17 inside the mixing tank 3, when the ring 17 rotates, the connecting shaft 18 will drive a set of connecting columns 19 to rotate, so that a set of second protrusions 21 contact the first protrusion 20. The ring 13 can act as a transmission hub to lift the ring 13, thereby driving the screening box 12 to complete the lifting and lowering movement, realizing the quantitative feeding of the equipment. By setting a cylinder 22 inside the mixing tank 3, and fixing a motor 23 to the top of the connecting plate 5, when the motor 23 rotates, the ring 17 will drive the connecting column 19 to rotate, so that the second protrusion 21 can lift the ring 13. When the connecting shaft 18 rotates, the raw materials inside the mixing tank 3 can be mixed. By fixing a spring 25 to the bottom of the first connecting block 11, when the motor 23 lifts the screening box 12 and then falls, the spring 25 can absorb the impact energy and increase the screening efficiency of the screening box 12. By opening a discharge port 26 at the bottom of the mixing tank 3 and penetrating the base 1, the mixed material can be discharged.
