Waste building block sorting device

Abstract

The invention discloses a waste building block sorting device and belongs to the field of waste building block treatment. The waste building block sorting device comprises a support. The support is connected with a conveying belt through a transmission shaft. A bottom plate is internally embedded in the conveying belt. A weighing plate is arranged on the bottom plate. By the adoption of the waste building block sorting device, waste blocks can be put on the weighing plate, a weighing sensor measures the weight of the blocks, when the blocks enter the lower portion of a shell, nitrogen is introduced into a sealed cavity through a gas inlet pipe, a deformable film is deformed along with increasing of the amount of the nitrogen in the sealed cavity and attached to the blocks gradually, when the deformable film abuts against a pressure sensor, the pressure sensor induces a pressure signal, when the pressure reaches a certain valve, the gas inlet pipe is closed, a gas outlet pipe is opened, the volume of the nitrogen is measured through a gas flowmeter on the gas outlet pipe, the volume in the shell is a fixed value, thus, the size of the blocks can be worked out, then the density of the blocks can be known, the blocks can be classified and subjected to crushing treatment correspondingly, the crushing effect is good, and the crushing efficiency is high.

Description

technical field [0001] The invention relates to the field of construction waste block processing, in particular to a construction waste block sorting device. Background technique [0002] A large amount of construction waste is generated when building or demolishing buildings, including waste concrete blocks, asphalt concrete blocks, metal blocks, bamboo wood blocks, etc. Due to the composition characteristics of construction waste and the fact that it is produced on the construction site, many construction wastes can be recycled. Therefore, it is very important to properly process and recycle construction waste. It not only meets the needs of ecological environment protection, but also meets the needs of sustainable development. When the existing devices process and recycle construction waste blocks, the construction waste blocks cannot be effectively and quickly screened. Separating and classifying, most of the different waste blocks are gathered together for crushing and...

Problems solved by technology

[0004] Aiming at the problems existing in the prior art that screening, separation and classification cannot be performed effectively and quickly, and materials of different densities are crushed at the same time, the effect of crushing treatment is not good, and the purpose of the present invention is to provide a sorting device for construction waste blocks, which Realize the separation of waste blocks of different densities and crush them separately, with good crushing effect
