Description

Technical Field

[0001] The utility model relates to the field of water reducing agent preparation, in particular to a raw material mixing device for preparing a water reducing agent. Background Art

[0002] Water reducers are concrete admixtures that reduce mixing water consumption while maintaining a relatively constant concrete slump. Most are anionic surfactants, including lignin sulfonates and naphthalene sulfonate formaldehyde polymers. When added to the concrete mix, they disperse cement particles, improving workability, reducing specific water usage, and improving the flowability of the concrete mix. Alternatively, they reduce specific cement usage, conserving cement.

[0003] For example, the authorization announcement number CN 216910177 U discloses a mixing device for processing polycarboxylic acid water-reducing agent raw materials, which relates to the technical field of polycarboxylic acid water-reducing agent processing, and includes: a feeding box. The utility model can add different raw materials to the interior of the No. 1 silo and the No. 2 silo by setting a No. 1 feeding pipe and a No. 2 feeding pipe respectively. During this process, the No. 1 gravity sensor and the No. 2 gravity sensor inside the No. 1 movable door and the No. 2 movable door can respectively weigh the raw materials entering the No. 1 silo and the No. 2 silo. The No. 1 motor can drive the stirring shaft and the stirring blade to rotate. The rotation of the stirring shaft can drive the lifting sleeve to move upward. The movement of the lifting sleeve can drive the No. 1 movable door and the No. 2 movable door to rotate downward through the linkage rod. The raw materials inside the No. 1 silo and the No. 2 silo will fall into the feeding box. At this time, the rotating stirring blades can break up the falling raw materials, so that the multiple raw materials can mix and react with each other, effectively avoiding the stratification of raw materials.

When the hard rotating tube 3 rotates, the hard water distribution pipe 301 is synchronously driven to rotate. When the hard water distribution pipe 301 rotates, the water reducer raw materials are synchronously stirred to improve the mixing efficiency. After the water reducer raw materials inside the mixing device 1 are discharged, they are connected to the water source through the water supply pipe 401, and the water source is pressurized and sent into the hard rotating tube 3 through the water supply pipe 401 by the booster pump, so that the hard rotating tube 3 diverts the pressurized water source to multiple hard water distribution pipes 301, and sprays it from the flat nozzle 302 on the hard water distribution pipe 301, performing high-pressure flushing on the inside of the mixing device 1, and cleaning the residual raw materials inside the mixing device 1.
