Description
Technical Field
The utility model belongs to the technical field of the technique of mortar production facility and specifically relates to a dry-mixed mortar conveyor is related to.
Background
The dry-mixed mortar is a mixture prepared by mixing cement serving as a main cementing material with dry-screened fine aggregate, a mineral admixture and an additive according to a certain proportion, and is a further revolution of building materials and building construction processes after concrete commercialization. With the need of social development, dry-mixed mortar is necessary to replace the traditional mortar.
However, the dry-mixed mortar still has many technical problems to be solved in the aspects of actual production and application, wherein one key problem is the 'segregation' problem of the dry-mixed mortar, which is known as the 'segregation' technical problem in the industry. The dry-mixed mortar is a mixture of discrete powdery and granular materials, and after the powdery and granular materials are mixed, secondary separation of powder and granules can occur in the processes of storage, transportation and use due to different properties of the powdery and granular materials, and the phenomenon is the 'segregation' phenomenon of the dry-mixed mortar.
If the segregation phenomenon can not be effectively controlled, the quality of the finished product of the dry-mixed mortar and the construction quality are seriously influenced. The segregation phenomenon of the dry-mixed mortar is a problem which is inevitably encountered and can not be avoided by all dry-mixed mortar production enterprises. In order to solve the problem, technicians in the industry finally find the reason for generating the 'segregation' of the dry-mixed mortar through methods such as analysis, investigation, experiment, adjustment and the like.
One of the reasons for the "segregation" of dry-mixed mortar is: because the angle of repose of the powder material (cement) and the particle material (sand) are different, when the dry-mixed mortar naturally forms a cone shape in the stacking process, the powder naturally stacks upwards along with the cone, and the particle materials such as sand and the like naturally slide downwards from the periphery of the cone, so that the generation of segregation is finally caused. The size of the drop height of the baiting determines the weight of the segregation of the powder material and the particle material. Different particulate materials "segregate" differently, such as river sand "segregates" less than other sand.
The second reason for the "segregation" of the dry-mixed mortar is: whether the materials in the material storage tank fall integrally or fall in a core-pulling manner, and whether the materials fall smoothly, are the key for causing the dry-mixed mortar to be separated. Most storage tank body's unloader all has the problem at present, and these devices are not being smooth and easy in the unloading of help material, but impel material "segregation".
The dry-mixed mortar is separated for the third reason: whether loading, pumping or storage tank blanking, the loading and blanking amount is large and the speed is high. Experiments show that the problem of 'segregation' of dry-mixed mortar with small material quantity, low blanking speed and high blanking speed is serious.
The utility model discloses a utility model that the bulletin number of authorizing is CN218465554U provides a continuous type mortar stirring conveyor, and the theory of operation is: the screw conveyer conveys the dry-mixed mortar in the movable silo into the stirrer, and the stirrer adds water into the dry-mixed mortar and uniformly stirs the dry-mixed mortar and then falls into a hopper of a mortar pump. The dry-mixed mortar in the movable silo is piled into a cone shape when falling into the spiral conveyer, and the particle materials in the dry-mixed mortar slide down from the periphery of the cone to cause segregation, so that the particle materials are not uniformly distributed in the powder materials when the dry-mixed mortar is conveyed to the dry-mixed mortar of the stirrer by the spiral conveyer, and the performance of the dry-mixed mortar is reduced.
