Machine-made sand sampling system and sampling method thereof

Abstract

The invention discloses a machine-made sand sampling system which comprises a stock bin (1), an air compressor (2), a collecting tank (3), a conveying device (4), an S-shape pipe (21), a first butterfly valve (5) and a second butterfly valve (6).The outlet end of the first butterfly valve (5) is connected with the upper end of the S-shape pipe (21), the lower end of the S-shaped pipe (21) is connected with the inlet end of the second butterfly valve (6), the outlet end of the second butterfly valve (6) stretches into the collecting tank (3), the side wall of the collecting tank (3) is provided with a stop valve (8), an annular pipe (9) is connected with the air compressor (2), an included angle is formed between a connecting wire which is arranged between a drive pulley (13) and a driven pulley (14) and the ground, and a conveyor belt (15) is located under the outlet end of a third butterfly valve (12).The invention further discloses a sampling method.The machine-made sand sampling system has the advantages of being safe, reliable, convenient to sample, capable of effectively preventing the dead mass phenomenon from occurring and rapid to respond.

Description

technical field [0001] The invention relates to the technical field of machine-made sand sampling for construction, in particular to a machine-made sand sampling system and a sampling method thereof. 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 engineering. [0003] Sand used in construction as construction ...

Problems solved by technology

The first step in testing the quality of machine-made sand is to obtain a sample of machine-made sand. In the past, machine-made sand was often not sampled, or tested after production, with a strong lag, and the environmental protection of the operating technology is also poor.

The purpose of this invention is to propose a new machine-made sand sampling system, which overcomes the disadvantages that machine-made sand cannot be detected or detected later

[0005] In addition, the machine-made sand in the silo is easy to accumulate tightly, and the phenomenon of accumulation and crushing occurs (immediately open the main outlet, the machine-made sand will still not fall under the action of gravity). To generate mechanical vibration around the warehouse to ease the accumulation of materials, which undoubtedly increases the labor intensity and reduces the production safety factor
