Problems solved by technology

[0005] The above-mentioned dry-mixed mortar metering equipment has the following defects: (1) About 150g to 200g of admixture is needed to produce 1 ton of dry-mixed mortar. The amount of admixture used is extremely small, and uneven mixing will lead to fluctuations in product quality and affect the use of mortar and performance
In order to ensure the mixing effect, it is usually necessary to prolong the stirring time, which undoubtedly increases the wear and damage of the stirring shaft and the stirring blade, shortens the service life of the mixer, and reduces the production efficiency at the same time.
(2) During the process of measuring the admixture by the load cell, due to the large vibration generated by the mixer when it is working, the mixing building is in an obvious swing environment, and the sensitive load cell is severely disturbed by the surrounding environment, and the sensor cannot distinguish whether it is from the surrounding environment. The load of the environment is still the load of falling materials, so the accuracy of the measurement results of the weighing scale cannot be guaranteed.
(3) The cementitious materials, admixtures and aggregates are directly leaked into the mixer, and the materials cause the gas in the limited space to rush out, which is likely to affect the accuracy of the metering equipment and also reduce the service life of the metering equipment
Therefore, the existing dry-mixed mortar metering equipment is difficult to meet the needs of mortar production

Abstract

The invention discloses a system for preparing dry-mixed mortar. The system comprises a conveying device (8), a spiral material conveying device (9), a lifter (10) and a two-stage metering device (11); the lifter (10) is composed of a bend (19) and a packing auger arranged in the bend (19), and the other end of the bend (19) is communicated with a stirrer (2); the two-stage metering device (11) is composed of a coarse additive bin (20), a fine additive bin (21), a vibrating disk A (22), a vibrating disk B (23), a weighing sensor A (24), a weighing sensor B (25), an overturning motor A (26) and an overturning motor B (27); and slopes are arranged on the top surface of the vibrating disk A (22) and the top surface of the vibrating disk B (23), and the vibrating disk B (23) is arranged below the discharging end of the coarse additive bin (20). The system has the beneficial effects that the production efficiency of the dry-mixed mortar is improved, the service life of the system is prolonged, accurate adding of an additive is achieved, and mixing of the additive is even.

Description

technical field [0001] The invention relates to the technical field of dry-mixed mortar preparation, in particular to a system and method for preparing dry-mixed mortar. Background technique [0002] Dry-mixed mortar is the most widely used type of ready-mixed mortar, and it is also the ultimate direction of the development of green building materials. As mortar for construction, dry-mixed mortar plays the role of bonding, lining, protection and decoration in thin layers in buildings and structures. With the improvement of the construction capacity of the modern construction industry, dry-mixed mortar is used as a flexible and sustainable construction The material not only meets the building performance, but also meets the construction needs of fast mechanized construction, large quantities, and rapid growth in instantaneous demand. It is widely used in construction and decoration projects. [0003] Dry-mixed mortar is made by mixing cementitious materials, aggregates, admi...
