Technical Field

[0001] The utility model relates to the technical field of water reducing agent mixing equipment, and more specifically, to a mixing system of a low air entraining polycarboxylic acid type high efficiency water reducing agent. Background Art

[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Most of them are anionic surfactants, such as lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it has a dispersing effect on cement particles, which can improve its workability, reduce unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement.

[0003] When people use a mixing device to stir the water reducer, since more than two mixed raw materials need to be put into the tank, people need to feed from multiple feeding ports, so this process will consume people's extra time. After the water reducer is mixed, since it contains solids and liquids, it is easy to get blocked inside the discharge channel during discharge, which reduces people's mixing efficiency of the water reducer.

[0006] As a preferred technical solution of the utility model, both sides of the tank body are longitudinally connected with guide rods, both sides of the cover plate are connected with second fixing plates, and the second fixing plates are slidably connected to the guide rods; this facilitates improving the stability of the cover plate lifting and lowering.

[0007] As an optimal technical solution of the utility model, the scraper is processed into an annular plate structure, and the end of the pull rod close to the scraper is covered with an elastic component, and the two ends of the elastic component are respectively connected to the cover plate and the scraper; it is convenient to drive the scraper to automatically reset and save people's physical energy.

[0008] As a preferred technical solution of the utility model, the stirring rods are distributed on the rotating shaft in a rectangular array, and the ends of the stirring rods away from the rotating shaft are in contact with the inner wall of the scraper to prevent position conflict between the scraper and the stirring rods.

[0009] As a preferred technical solution of the utility model, the side of the bottom plate away from the rotating shaft is in contact with the groove, and one side of the discharge pipe corresponds to the groove and the spiral auger, so as to facilitate the discharge of the mixed material.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: by separating the tank body and the cover plate, the cover plate is raised and lowered by the cooperation between the cylinder and the guide rod, which makes it convenient for people to directly put the materials to be mixed into the tube body, opens up the space for feeding, greatly improves people's efficiency when feeding, and thus saves feeding time; the pull rod, elastic component and scraper arranged on the cover plate cooperate with each other to remove the materials attached to the inner wall of the tank body, which not only reduces the waste of materials, but also saves people's physical strength when cleaning, and facilitates people to clean the inside of the tank body in time; the spiral auger arranged at the bottom of the tank body can evenly discharge the stirred materials from the discharge port, thereby preventing the material from being blocked during discharge, and effectively improving the production efficiency of the water reducer.
