Method and apparatus for preparing mixture and removing sticky material on scale

Abstract

The invention relates to a method and apparatus for preparing a mixture, and discloses a method and apparatus for preparing the mixture and removing a sticky material on a scale. The method for removing the sticky material on the scale is characterized in that a first solid material scours the sticky material on the scale at a predetermined speed, the sticky material on the scale is formed by a second solid material adhered to the scale (1), and the adhesiveness of the second solid material is higher than that of the first solid material. The method and the apparatus can well remove the sticky material on the scale, and avoid corrosion and other adverse influences on a metering device and relevant electrical devices.

Description

technical field [0001] The invention relates to a preparation method and equipment for mixed materials, in particular, to a method and device for removing sticky materials from a weighing hopper. On this basis, the present invention also relates to a method and equipment for preparing the mixed material. Background technique [0002] Dry-mixed mortar is one of the emerging dry-mixed materials in the field of building materials, and is also commonly referred to as hydraulic cement-mixed mortar. Dry-mixed mortar is made by mixing dry and sieved sand, powder and additives in proportion. Among them, typically, the sand is quartz sand, the powder is an inorganic gel material such as cement, and the additive may be a polymer for enhancing physical properties. After the dry-mixed mortar is transported to the construction site in bags or in bulk, it can be used directly after adding water and mixing, which can effectively improve the project quality and construction environment, a...

Problems solved by technology

On the one hand, in order to ensure the cleaning effect, the vibrating force of the vibrator needs to be set relatively large, which will cause the installation of the scale bucket 1 to be not stable enough, which will affect the measurement accuracy in the subsequent measurement, and easily cause the weld seam of the scale bucket 1 to crack, affecting service life; on the other hand, practice has proved that the cleaning effect by vibration is not ideal, and some materials still remain on the inner wall of the scale bucket 1 after cleaning

[0006] In addition, in the related field, methods and devices for removing sticky material by setting cleaning devices on the inner wall of the weighing hopper and flushing with water are provided, but these methods are not suitable for the preparation of dry-mixed mortar.

[0007] In fact, in the process of metering and preparing other mixed materials than dry-mixed mortar, it is often inconvenient to implement the method for removing sticky material in the weighing hopper provided in the above-mentioned prior art

For example, in some metering equipment, it is necessary to avoid contact with water vapor as much as possible to reduce the corrosion of metal or the influence of related electrical equipment, so the cleaning method of water flushing cannot be implemented

[0008] In addition, in the preparation of some mixed materials, although the requirements for the ratio of each component in the mixed material may not be strict, if the mixed material to be prepared does not need (or temporarily) to add water, it is also not possible to use water to rinse. method of removal

[0009] In summary, there is a technical problem that the sticky material in the scale bucket is not easy to remove in the preparation of proportional dry mixture such as dry-mixed mortar. In view of this, it is necessary to provide a new method and device for removing the sticky material in the scale bucket
