Embodiment Construction
[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0030] Such as Figure 1 to Figure 5 As shown, a layered multi-stage concrete mortar preparation and mixing process uses a concrete mortar preparation device, which includes a mixing cylinder 1, a processing unit 2, an additive cylinder 3 and a water injection unit 4 The method for mixing concrete by using the above-mentioned concrete mortar preparation device also includes the following steps:
[0031] S1, feeding operation: import sand and cement from the feeding port 22 into the processing cylinder 21 by manual or mechanical assistance;
[0032] S2. Milling operation: the sandstone and cement introduced into the processing cylinder 21 in the step S1 are stirred and milled by the milling mechanism 25 to form mortar;
[0033] S3. Adding operation...

The invention relates to a hierarchical multi-grade type concrete mortar preparation material mixing treatment technology adopting a concrete mortar preparing device. The concrete mortar preparing device comprises a mixing cylinder, a treatment unit, an additive cylinder and a water feeding unit. The treatment unit is arranged at the upper end of the mixing cylinder. The left end of the mixing cylinder is connected with the water feeding unit through a pipeline. The right end of the treatment unit is connected with the additive cylinder through a pipeline. By designing the pagoda type multi-grade structure of the material mixing device, the manner of feeding sand, stone and cement at the first grade, feeding various additives at the second grade, feeding water at the third grade is adopted, each step of the technology is treated in a separated manner, and then the problem that since residual additives and moisture can conduct a reaction with the sand, stone and cement earlier, the strength of the concrete is lowered is solved. According to the hierarchical multi-grade type concrete mortar preparation material mixing treatment technology, by feeding the mortar at a fixed quantity and then feeding water at a fixed volume, the problem that due to excessively fed water, the strength and viscosity of the concrete are influenced is solved.
Description
technical field [0001] The invention relates to the technical field of construction material preparation, in particular to a layered and multistage concrete mortar preparation and mixing process. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. . Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. [0003] The following problems often exist in the process of preparing concrete mortar and mixing materials: 1. The existing equipment often adds raw materials in a mixing drum for mixing and stirring. This process will cause a small amount of additives and moisture to...
