Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, in particular to a magnesium phosphate cement concrete mixing device. Background Art

[0002] Magnesium phosphate cement is mainly made of dead-burned magnesium oxide, phosphate and retarder in a certain proportion. It is a cementitious material that forms strength by producing chemical bonds through chemical reactions. Its performance is between that of ceramics and cement. It has the advantages of fast hardening and early strength, strong adaptability to environmental temperature, high bonding strength with old concrete, small volume deformation, and good durability such as wear resistance, frost resistance, and resistance to salt-freeze erosion.

[0003] The Chinese utility model patent with the announcement number CN218593322U discloses a magnesium phosphate cement concrete mixing device, including a mixing box, a mounting frame, a double-shaft motor, a speed reduction mixing structure, an electromagnetic clutch, a driving screw, a scraper ring, a lower pressure rod, a sliding plate, a fixed plate, a reducer, a mixing shaft, a mixing rod, a feeding port, and a discharging pipe. A mounting frame is fixedly installed above the mixing box, and a double-shaft motor is fixedly installed on the mounting frame; a speed reduction mixing structure is installed on the mixing box; an electromagnetic clutch is fixed on the upper end of the mounting frame, and the electromagnetic clutch is connected to the upper output end of the double-shaft motor, and a driving screw is fixedly installed on the upper end of the electromagnetic clutch; a scraper ring is slidably embedded in the mixing box, and two lower pressure rods are fixed on the scraper ring, and the lower pressure rod slides upward through the upper wall of the mixing box, and a sliding plate is fixedly connected to the upper end of the lower pressure rod, and the sliding plate is snap-fitted on the driving screw. The application completes the cleaning operation of the inner wall of the mixing box that has solidified and bonded through the up and down movement of the scraper ring.

It is easy for the magnesium phosphate cement and water to be insufficiently mixed, resulting in the formation of magnesium phosphate cement particles and cannot be used normally.
