Problems solved by technology
However, due to the height of nearly 4 meters from the top to the bottom of the silo, the materials are affected by air resistance during the falling process, and the materials with different specific gravity begin to stratify, and the material surface cannot drop smoothly when the material is discharged, and the material is affected by the angle of repose. segregation will also occur, which will affect the on-site use effect of dry-mixed mortar
[0004] In order to solve the segregation problem of dry-mixed mortar in bulk mobile silos, there are currently two methods: one is to reduce the falling height of materials; the other is secondary mixing, and the effect of these methods in practical applications is not obvious
The segregation problem of dry-mixed mortar has not been effectively solved. Some data show that after using the above two methods, the dispersion coefficient of 75um pass rate still reaches more than 20%, and the field use effect of dry-mixed mortar is not good.
[0005] It can be seen that the segregation problem of dry-mixed mortar transported to bulk mobile silos has not been effectively solved, and it is urgent to develop an effective method to solve the segregation problem of dry-mixed mortar to ensure the on-site use effect of dry-mixed mortar

Embodiment Construction
[0028] The purpose, technical solution and beneficial effects of the present invention will be further described in detail below.
[0029] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the claimed invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
[0030] In order to solve the segregation problem in the falling process of the dry-mixed mortar, the present invention dynamically adjusts the height difference between the dry-mixed mortar inlet and the material receiving surface, and stably sets the height difference within a certain range. Within this range of height difference, the falling time of the material is short, the stratification is not obvious, and at the same time, the falling of the material surface is stable.

The invention provides an anti-segregation device. The device comprises a material carrying component (1) for carrying a fallen material and a height adjusting mechanism (2), wherein the height adjusting mechanism (2) is used for adjusting a height difference between the material carrying component (1) and a material falling starting position. The invention also provides a dry mixed mortar bulk movable silo with the anti-segregation device. In the anti-segregation device and the dry mixed mortar bulk movable silo provided by the invention, because the height difference between a dry mixed mortar feed port and a material carrying surface is dynamically adjusted and stably set in a certain range, and the material carrying surface is controlled to stably fall, the problem of segregation during falling of the material is effectively solved.
Description
technical field [0001] The invention relates to the field of dry-mixed mortar transportation equipment, in particular to an anti-segregation device and a dry-mixed mortar bulk mobile silo provided with the anti-segregation device. Background technique [0002] Dry-mixed mortar is made by physically mixing aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) with different specific gravity and diameter after drying and screening in a certain proportion. A granular or powdery material. It is usually transported to the construction site in bags or in bulk, and can be used directly after mixing with water. Dry-mixed mortar can play the role of bonding, lining, protection and decoration in thin layers, and has been widely used in construction and decoration projects. [0003] For the transportation of dry-mixed mortar on the construction site, the pneumatic conveying method is mainly used to transport the dry-mixed...
