Embodiment 1

[0044] Such as figure 1 , 3 As shown, the automatic sorting method of this embodiment includes the following steps.

[0045] In step 1, the construction waste is crushed by a crusher, and the construction waste is broken into multiple material blocks, and the size of each material block is smaller than or equal to a preset size, for example, the preset size is 120mm in diameter.

[0046] Step 2, remove the ferromagnetic impurities and light waste in the material blocks in turn, the remaining material blocks are mainly concrete material blocks and brick material blocks, and send multiple material blocks to the transmission plate of the transmission device 2; this embodiment In this method, the front end of the conveying device 2 is provided with a feeding trough 1; in this step 2, a plurality of material blocks are placed in the feeding trough 1, and the material blocks flow from the outlet of the feeding trough 1 to the conveying plate of the conveying device 2 superior. In...

Embodiment 2

[0053] The scheme of this embodiment is basically the same as that of Embodiment 1, the difference is that in this embodiment, step 3 also includes the step of identifying the weight feature of the current material block through the pressure sensor installed at the bottom of the conveying plate, so as to obtain the weight Identification data; in this embodiment, the pressure sensor is installed at the bottom of the material guide gate.

[0054] In step 4, the pre-stored data includes pre-stored weight data, and the threshold includes a third threshold; if the similarity between the weight identification data and the pre-stored weight data is greater than the third threshold (for example, the similarity between the weight identification data and the pre-stored weight data is greater than 80%) ), then perform step 5; otherwise perform step 6; in this embodiment, in order to ensure that the pressure sensor is always in a high-precision state, when the weight of the current materia...

Abstract

The invention discloses an automatic sorting method for construction waste. The automatic sorting method comprises the following steps that firstly, the construction waste is crushed into material blocks; secondly, ferromagnetic impurities and light waste materials are removed, and the material blocks are conveyed to a conveying plate of conveying equipment; thirdly, feature identification is carried out on the current material blocks to obtain identification data; fourthly, the identification data are compared with the pre-stored data, and the similarity value of the identification data and the pre-stored data is obtained; if the similarity value is greater than or equal to the threshold value, the fifth step is executed; and otherwise, the sixth step is executed; fifthly, a material guide gate of the conveying plate below the current material blocks is driven to open so that the material guide gate can leak the current materials downward and the third step can be executed; and sixthly, the current material blocks are continuously conveyed forward, and the third step is executed. By the adoption of the automatic sorting method for the construction waste, the construction waste canbe effectively identified and sorted, the automatic diversion of brick materials and concrete materials is effectively realized, the sorting efficiency is improved, the harm to workers is avoided, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, more specifically, the invention is an automatic sorting method for construction waste. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, demolition or repair of various buildings by construction units or individuals. If the construction waste cannot be cleaned up in time, it will damage the environment, endanger people's health, bring inconvenience to people's life, and restrict the development of the city. At present, it is an effective measure for sustainable development to make use of the resource properties of construction waste and regenerate building materials through construction waste. [0003] Aiming at the problem of a wide variety of incoming construction waste, the traditional method is to rely on manual differentiation and sorting. This method has the followin...
