Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a polycarboxylate high-performance water-reducing agent feeding device. Background Technology

[0002] Polycarboxylate superplasticizer is a high-performance water-reducing agent and a cement dispersant used in cement concrete. It is widely used in highway, bridge, dam, tunnel, and high-rise building projects. This product is environmentally friendly, non-flammable, non-explosive, and can be safely transported by train and truck.

[0003] Existing polycarboxylate superplasticizer feeding devices typically add the superplasticizer at a fixed location, a single point. This limitation of the addition method and the area covered by the addition increases the mixing and reaction time between the added superplasticizer and the material, thereby reducing production efficiency.

[0026] The filling assembly 4 includes a rotating arm 15, a connecting rod 16, and a piston 17. A support 12 is provided on the filling cylinder 3. The rotating arm 15 is rotatably mounted on the support 12. The connecting rod 16 is hinged to the rotating arm 15. The piston 17 is hinged to the connecting rod 16 and slidably mounted inside the filling cylinder 3. The bottom of the filling cylinder 3 is provided with a filling pipe 13 and a suction pipe 14. The suction pipe 14 extends into the storage tank 2, and the filling pipe 13 extends into the mixing tank 1. Several sets of filling pipes 13 are provided, and the sets of filling pipes 13 are arranged in a ring array. A first one-way valve 36 is provided on the filling pipe 13, and a second one-way valve 37 is provided on the suction pipe 14. A groove 20 is provided on the rotating arm 15. A lead screw 18 is rotatably mounted in the groove 20. A slider 19 is threadedly connected to the lead screw 18. The slider 19 is slidably mounted in the groove 20, and the connecting rod 16 is hinged to the slider 19.

[0027] The mixing assembly 5 includes a stirring shaft 21 and a stirring paddle 22. The stirring shaft 21 is rotatably disposed inside the mixing tank 1, and the stirring paddle 22 is disposed on the stirring shaft 21.

[0028] Drive assembly 6 includes a motor 23, a first pulley 24, a second pulley 25, a first transmission belt 26, a third pulley 27, a fourth pulley 28, a second transmission belt 29, a first bevel gear 30, and a second bevel gear 31. The motor 23 is mounted on the storage box 2. The first pulley 24 is sleeved on the output shaft of the motor 23. A first rotating shaft 32 is rotatably mounted on the bracket 12. A rotating arm 15 is mounted on the first rotating shaft 32. The second pulley 25 is sleeved on the first rotating shaft 32. A transmission belt 26 is sleeved on the first pulley 24 and the second pulley 25, a third pulley 27 is sleeved on the output shaft of the motor 23, a second rotating shaft 33 is rotatably mounted on the top of the mixing tank 1, a fourth pulley 28 is sleeved on the second rotating shaft 33, a second transmission belt 29 is sleeved on the third pulley 27 and the fourth pulley 28, a first bevel gear 30 is sleeved on the second rotating shaft 33, and a second bevel gear 31 is sleeved on the stirring shaft 21 and meshes with the first bevel gear 30.

[0029] In practical use, the polycarboxylate high-performance water-reducing agent is added to the storage tank 2, and the material is added to the mixing tank 1. When in use, the motor 23 is started, which drives the first pulley 24 and the third pulley 27 to rotate. The first pulley 24 drives the second pulley 25 to rotate through the first transmission belt 26. The second pulley 25 drives the first rotating shaft 32 to rotate. The first rotating shaft 32 drives the rotating arm 15 to rotate. The rotating arm 15 drives the piston 17 to reciprocate up and down through the connecting rod 16. When the piston 17 rises, the polycarboxylate high-performance water-reducing agent in the storage tank 2 is drawn into the filling cylinder 3. When the piston 17 falls, the polycarboxylate high-performance water-reducing agent in the filling cylinder 3 is sent into the mixing tank 1 through the filling pipe 13. The polycarboxylate high-performance water-reducing agent can be added at multiple points through several sets of filling pipes 13. The polycarboxylate high-performance water-reducing agent can be added intermittently in small amounts through the reciprocating up and down of the piston 17. The water-reducing agent enters the mixing tank 1 and mixes with the material. The third pulley 27 drives the fourth pulley 28 to rotate through the second transmission belt 29. The fourth pulley 28 drives the second rotating shaft 33 to rotate. The second rotating shaft 33 drives the first bevel gear 30 to rotate. The first bevel gear 30 drives the second bevel gear 31 to rotate. The second bevel gear 31 drives the stirring shaft 21 and the stirring paddle 22 to rotate, thus stirring the water-reducing agent and the material.

[0030] According to actual usage requirements, the reciprocating stroke distance of piston 17 can also be adjusted. To adjust, simply rotate screw 18, which drives slider 19 to move. By adjusting the position of slider 19, the stroke distance of piston 17 can be adjusted, thereby changing the amount of water-reducing agent added at one time.

[0031] In summary, this solution includes a filling assembly 4 with several sets of filling pipes 13. These pipes allow for multi-point filling of the polycarboxylate superplasticizer, while the filling assembly 4 enables intermittent, small-volume filling, facilitating more thorough and uniform mixing of the superplasticizer and the material, reducing mixing time, and improving production efficiency. The screw 18 drives the slider 19, and adjusting the position of the slider 19 adjusts the stroke distance of the piston 17, allowing for changes in the single filling amount of the superplasticizer according to actual needs. The motor 23 drives the piston 17 to reciprocate, adding the superplasticizer, and simultaneously drives the stirring shaft 21 and the stirring paddle 22 to mix the material and the superplasticizer.
