Dust-fall environment-friendly concrete aggregate mixing device and use method thereof

Abstract

The invention discloses a dust-fall environment-friendly concrete aggregate mixing device and a use method thereof, and belongs to the technical field of concrete machining. The dust-fall environment-friendly concrete aggregate mixing device is provided with a specially-made dustproof linkage assembly and a material conveying and guiding assembly, in the feeding process, aggregate can be firstly contained in a material conveying hopper, then the outer side of the material conveying hopper is covered with a dustproof cover, a hand pull ring arranged on the outer side of the dustproof cover can be pulled to control starting of feeding, so that when feeding is carried out in a mixing box, the dustproof cover can play a role in sealing protection, dust is effectively prevented from overflowing, the dust can be effectively prevented from polluting the environment and harming the body health of workers, the environmental protection performance and the practicability are remarkably improved, friction and collision between the aggregate and the inner wall of a feeding pipe can be effectively avoided, dust is remarkably reduced, and dust generated when the aggregate is contained in the material conveying hopper can be remarkably reduced through the arrangement of water tanks, micro water pumps, atomization spray heads and a power supply assembly.

Description

Technical field [0001] The present invention relates to the field of concrete processing techniques, and more particularly to a mixture of dust-free environmentally-protected concrete aggregate mixing devices and methods of use.

Rough bones refers to pebbles, gravel, etc., fine aggregate refers to natural sand, artificial sand, etc. The aggregate having a particle size greater than 4.75 mm is called a coarse aggregate, commonly known as the stone. Commonly used gravel and pebbles. Crushed stone is a rock or rock. The aggregate of 4.75 mm or less of the particle size is referred to as fine aggregate, commonly known as sand. Sand is divided into natural sand and artificial sand in accordance with the source.

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
