Description

Technical Field

[0001] This utility model relates to the field of engineering raw material production equipment, and in particular to a batching device for producing concrete water-reducing agents. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of mixing water while maintaining a relatively constant concrete slump. Most water-reducing agents are anionic surfactants, including lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixes, they disperse cement particles, improve workability, reduce water consumption per unit area, and enhance the fluidity of the concrete mixture.

[0003] The production of concrete water-reducing agents requires heating and stirring of raw materials to ensure thorough mixing. However, during mixing, the raw materials may clump together, sinking to the bottom of the mixing tank. Conventional mixing rollers are inconvenient for breaking up these clumps, preventing proper mixing. Therefore, a batching device for concrete water-reducing agent production is needed to easily break up the clumps at the bottom of the mixing tank, thereby improving the mixing efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the defect that the raw material blocks of water-reducing agent that sink to the bottom of the mixing tank are inconvenient to break up, and to provide a batching device for the production of concrete water-reducing agent.

[0005] The technical solution to achieve the above objective is: a batching device for producing concrete water-reducing agent, comprising a mixing tank, a feed pipe at the top of the mixing tank, a discharge pipe at the bottom of the mixing tank, a drive motor connected to the top of the mixing tank, a drive shaft connected to the output end of the drive motor, a plurality of main mixing rods connected to the side wall of the drive shaft, a drive mechanism provided inside the mixing tank, and a crushing mechanism provided on the drive mechanism and the drive shaft.

[0006] Preferably, the bottom of the drive shaft is located at the inner bottom of the mixing tank, and the main stirring rod is located inside the mixing tank.

[0007] Preferably, the driving mechanism includes a bottom cylinder, a rotating ring, a steering gear, a rotating shaft, a driving gear, and a gear ring. The bottom of the mixing tank has a rotating groove, and a rotating ring is rotatably connected in the rotating groove. The top of the rotating ring is connected to the bottom cylinder, and the top of the bottom cylinder has a rotating hole. The side wall of the rotating hole is rotatably connected to the driving shaft, and the bottom of the driving shaft is connected to the driving gear. The inner side wall of the bottom cylinder is connected to the gear ring, and the bottom of the mixing tank is rotatably connected to the rotating shaft. The side wall of the rotating shaft is connected to the steering gear.

[0008] Preferably, the sidewall of the steering gear meshes with the ring gear, and the steering gear meshes with the drive gear.

[0009] Preferably, both the steering gear and the drive gear are located inside the bottom cylinder.

[0010] Preferably, the crushing mechanism includes a first base plate, a first tooth groove, a first crushing tooth, a second base plate, a second tooth groove, and a second crushing tooth. The bottom sidewall of the drive shaft is connected to multiple first base plates. The bottom sidewall of the first base plate has multiple first tooth grooves. The bottom end of the first base plate is also connected to multiple first crushing teeth. The sidewall of the bottom cylinder is connected to a second base plate. The top end of the second base plate has multiple second tooth grooves. The top end of the second base plate is also connected to multiple second crushing teeth.

[0011] Preferably, the first base plate is located above the bottom cylinder, the width of the first tooth groove is equal to the width of the second tooth groove, the width of the first crushing tooth is equal to the width of the second crushing tooth, and the width of the first crushing tooth is less than the width of the first tooth groove.

[0012] Preferably, the first tooth groove and the second crushing tooth are matched vertically, the second tooth groove and the first crushing tooth are matched vertically, the first crushing tooth and the second crushing tooth are both pyramidal, and the bottom end of the side wall of the second base plate is connected to an inclined plate.

[0013] The beneficial effects of this utility model are as follows: the bottom cylinder drives the second bottom plate to rotate, while the drive shaft drives the first bottom plate to rotate, so that the rotation direction of the first bottom plate is opposite to that of the second bottom plate, allowing the first bottom plate and the second bottom plate to rotate in a staggered manner. This allows the first crushing tooth to pass through the second tooth groove during rotation, while the second crushing tooth passes through the first tooth groove, thereby breaking and cutting the raw material clumps located between the first bottom plate and the second bottom plate, thus improving the mixing efficiency of the raw materials. At the same time, the second bottom plate drives the inclined plate to rotate, which can scoop up the raw material clumps in contact with the bottom of the mixing tank, allowing the raw material clumps to be better mixed.
