Description

Double-pouring stirring arrangement structure for aerated concrete production Technical Field The utility model relates to the technical field of aerated concrete production, in particular to a double-pouring stirring arrangement structure for aerated concrete production. Background The common batching system of the aerated concrete production line is that the bottom of a powder bin is connected with a screw conveyor to convey powder to a powder scale, the outlet of the bottom of the powder scale is connected with a control valve and then connected with the screw conveyor, and the weighed powder is conveyed to a pouring mixer. And when the beat is slow, the production line adopts a pouring stirrer, and the pouring stirrer is correspondingly provided with a set of batching system. And the large production line, because of fast beat, sometimes needs to be provided with two pouring mixers, and correspondingly two independent batching systems are provided. At this time, the powder balance and the screw conveyor are provided with two sets, and the cost is high. In addition, because of the large number of devices and large occupied space, the batching plant is correspondingly large, and the civil construction cost is high. The prior reference CN202121768584.9 double-mold pouring mixer is characterized in that a material distribution adjusting plate is further arranged at the joint of the tee joint in the middle of the discharge pipe, so that raw materials capable of stirring two molds at one time are poured into two molds, and the production efficiency is improved. The comparison document adopts the fine adjustment of the material distribution adjusting plate to enable the pipelines at two sides to be fed with the raw materials with the same quantity of the die, firstly, how the material distribution adjusting plate is adjusted is not described, and the adjustment is performed through what feedback is not described, and the person in the field can only judge the feeding quality by adding a weighing structure in the die, so that the deviation of the powder adjusting plate is adjusted through an external structure by the mass, and the die powder quality is overloaded easily. The mixed powder needs to be poured in the pouring mixer, the specific mass is needed, otherwise, the corresponding gas generating agent, water and gas stabilizing agent all need to be changed proportionally, and for practical addition convenience, the mass of the mixed powder needs to be controlled from a powder scale, so that the stirring and the subsequent process can be realized by adding other ingredients into the pouring mixer in equal quantity. A special screw conveyor pipe is required to realize the sharing of two groups of powder scales.
