Description

Technical Field

[0002] Cement mortar is an important building material, usually a gray powdery substance, mainly used in the preparation of concrete, mortar and other composite materials. Cement mortar is widely used in the construction field for wall construction, paving, manufacturing prefabricated components, and repairing and reinforcing structures.

[0003] When making cement mortar, cement mixing is required. Cement mixing refers to the process of mixing a certain amount of cement, coarse material, fine material and water in a mixing barrel to obtain cement mortar with specific properties. Finally, the mixed cement mortar is transferred to the required location in the construction project through the grouting equipment.

[0004] At present, in the existing cement mixing device for cement mortar in construction engineering, when mixing, generally a certain amount of cement and water are first injected into the mixing barrel and stirred to form cement liquid, and then the coarse material pipe and the fine material pipe are all put into the mixing barrel for stirring and mixing. Moreover, the coarse material pipe, the fine material pipe and the mixing barrel are mostly in a fixed feeding state with each other, which reduces the effective feeding contact area of ​​the cement liquid when the coarse material and the fine material are put into the mixing barrel. In addition, since the coarse material and the fine material cannot be quantitatively mixed and put into the mixing barrel respectively, the sufficient mixing degree between the mixing barrel and the cement liquid put into the coarse material and the fine material is low, thereby reducing the mixing quality of the final cement mortar product of the cement mixing device for cement mortar in construction engineering.

According to the prior art, the amount of coarse material and fine material quantitatively put into the mixing barrel 1 can be controlled respectively by the metering controller.

[0026] The first injection opening 13 and the second injection opening 14 are both rectangular long strip openings. The coarse material pipe 32 is longitudinally slidably connected to the first injection opening 13, and the fine material pipe 42 is longitudinally slidably connected to the second injection opening 14, so as to realize the longitudinal reciprocating feeding effect of the coarse material pipe 32 and the fine material pipe 42 respectively, and realize the effect of dispersing the feeding, contacting with the cement liquid and fully mixing.

[0027] The bulk material tray 63 is arranged at the top end of the main shaft 62. The top end of the bulk material tray 63 is an arc-shaped structure and does not contact the lower end surface of the injection tube 11. When the unmixed liquid of cement and water is injected into the mixing barrel 1 through the injection tube 11, the cement and water fall on the top end of the bulk material tray 63 and are evenly dispersed and fall into the mixing barrel 1, so as to prepare for comprehensive and sufficient stirring in the later stage to form a cement liquid effect.

[0028] There are six stirring blades 7 arranged in a circle, and three mixing ports 71 arranged in transverse directions, each group of four stirring blades arranged vertically and passing through the stirring blades 7. When the stirring blades 7 rotate at a uniform speed, cement liquid, coarse material and fine material can pass through each mixing port 71 and form multiple thin streams, which greatly improves the mixing effect.

[0030] The top cross-section of the fixed plate 2 is a T-shaped structure, and the connecting frame 51 is a Z-shaped structure as a whole and is fixed to the piston rod of the reciprocating cylinder 5 and the mixing barrel 1 respectively. The reciprocating cylinder 5 can realize the reciprocating movement of the mixing barrel 1 along the guide groove 21 according to a certain longitudinal reciprocating distance through the guide slide rod 22.

[0031] The guide slide groove 21 and the guide slide rod 22 form a group, which are two symmetrically arranged groups in total. The guide slide rod 22 is fixed to the mixing barrel 1. The sliding connection part between the guide slide rod 22 and the guide slide groove 21 has a trapezoidal structure in the front view cross section, which ensures the stability of the guide slide rod 22 sliding longitudinally along the guide slide groove 21 and avoids slipping.

[0032] Working method: first start the motor 6 to drive the stirring blade 7 to rotate at a uniform speed, then inject a certain amount of unmixed liquid of cement and water into the mixing barrel 1 through the injection pipe 11, the cement and water fall on the top of the bulk material plate 63, and then disperse and fall evenly and are fully stirred and mixed by the stirring blade 7 and the mixing port 71 to form cement liquid, further improving the stirring and mixing degree of the formed cement liquid.

[0033] Next, when the cement liquid is formed, the coarse material adjusting pump 31 and the fine material adjusting pump 41 can be started, and the reciprocating cylinder 5 can be started at the same time, thereby driving the mixing barrel 1 to move back and forth longitudinally. The coarse material adjusting pump 31 will draw a certain amount of coarse material from the coarse material tank 3, and then scatter it longitudinally and reciprocatingly in the mixing barrel 1 evenly through the coarse material pipe 32 and the first injection port 13. At the same time, the fine material adjusting pump 41 will draw a certain amount of fine material from the fine material tank 4, and then scatter it longitudinally and reciprocatingly in the mixing barrel 1 evenly through the fine material pipe 42 and the second injection port 14. The evenly scattered coarse material and fine material will be fully and effectively stirred and mixed with the cement liquid, thereby achieving that the coarse material and fine material put into the mixing barrel 1 greatly increase the effective feeding contact area with the preset cement liquid, and then fully mix and stir, thereby improving the overall sufficient mixing degree between the mixing barrel 1 put into the coarse material and fine material and the cement liquid, thereby improving the mixing quality of the cement mixing device for cement mortar in the construction project for the final cement mortar product.
