Embodiment Construction
[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.
[0030] Such as figure 1 As shown, a method for determining the pouring time of gypsum slurry comprises the following steps:
[0031] 1) Extract the structural model according to the actual gypsum slurry pouring bin, the upper half of the gypsum slurry pouring bin involved in the present invention is a cylindrical bin, and the lower half is a structure of a conical hopper, such as figure 2 shown;
[0032] 2) The establishment of the slurry flow formula at the outlet of the gypsum slurry filling bin. According to the structural model established in step 1), considering that the gypsum slurry is a uniform solid-liquid mixed viscous non-Newtonian fluid, the viscous fluid ...

The invention discloses a gypsum slurry pouring time calculation method. The gypsum slurry pouring time calculation method particularly comprises the following steps of (1) gypsum slurry pouring bin structural model extraction, (2) gypsum slurry pouring bin discharge hole flow formula building, (3) cylinder stress analysis, (4) cone stress analysis, (5) calculation of pressure difference delta p at a discharge hole of a pouring funnel, and (6) gypsum slurry pouring time calculation model formula building. The gypsum slurry pouring time calculation method is applied to a pouring mechanism in a gypsum stirring bin commonly adopted in gypsum block production lines, complex mechanical properties in the gypsum slurry pouring process are analyzed, the gypsum slurry pouring time calculation method is obtained under the guidance of the mechanics of viscous fluids, the complex way of artificial experiments is replaced, gypsum slurry pouring time is accurately calculated, and the failure occurrence rate of the production lines is decreased.
Description
technical field [0001] The invention relates to the technical field of gypsum block production, in particular to a calculation method for obtaining a suitable pouring time of gypsum slurry through the theory of viscous fluid mechanics. Background technique [0002] With the improvement of people's awareness of environmental protection, gypsum blocks, as a recognized green and energy-saving material, are widely used in architectural decoration and other fields due to their excellent performance. . Therefore, the research on the production process and equipment of gypsum blocks has always been one of the important topics of many scientific research institutions and manufacturers. [0003] The production process of gypsum blocks includes powder distribution, mixing and molding, slurry pouring, demoulding and other processes, and there is a timing coordination between each step-by-step process. The timing of each process of gypsum block production is subject to the initial set...
