A kind of dust-reducing environment-friendly concrete aggregate mixing device and using method thereof

Abstract

The invention discloses a dust-reducing and environment-friendly concrete aggregate mixing device and a method for using the same, which belong to the technical field of concrete processing and can be equipped with a special dust-proof linkage component and a material transporting component. Fill the aggregate into the hopper, then put the dust cover on the outside of the hopper, and control the start of feeding by pulling the handle ring on the outside of the dust cover, so that when feeding into the mixing box , the dust cover can play a role of sealing protection, effectively prevent dust from overflowing, and then effectively prevent dust from polluting the environment and endangering the health of workers, significantly improving environmental protection performance and practicability, and can effectively avoid aggregate Friction and collision with the inner wall of the feed pipe can significantly reduce the generation of dust, and through the settings of the water tank, micro-water pump, atomizing nozzle, and power supply components, the dust generated when loading aggregates into the hopper can be significantly reduced .

Description

technical field [0001] The invention relates to the technical field of concrete processing, and more particularly, to a dust-reducing and environment-friendly concrete aggregate mixing device and a method for using the same. Background technique [0002] Concrete aggregate is concrete aggregate, which refers to the granular loose material that plays the role of skeleton or filling in concrete. Divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, gravel, etc., and fine aggregate refers to natural sand, artificial sand, etc. Aggregates with a particle size larger than 4.75mm are called coarse aggregates, commonly known as stones. Commonly used are gravel and pebbles. Crushed stone is a rock particle with a particle size larger than 4.75mm, which is made of natural rock or rock by mechanical crushing and screening. The aggregate with a particle size of 4.75mm or less is called fine aggregate, commonly known as sand. Sand is divided into nat...

Problems solved by technology

[0004] In the production process of mixed aggregate concrete, it is necessary to mix coarse aggregate and fine aggregate. When feeding the existing concrete aggregate mixing device, the aggregate is usually directly fed into the device through the feeding pipe. The friction and collision between the aggregate and the inner wall of the feeding pipe, as well as the impact when it falls to the bottom of the device, will cause dust to rise up, and since the feeding pipe cannot be sealed during feeding, a large amount of dust will pass through the feeder. The overflow of the material pipe will not only pollute the environment, is not conducive to environmental protection, but also endanger the health of the staff. Therefore, we propose a dust reduction and environmental protection concrete aggregate mixing device and its use method
