Example Embodiment

[0049] Example one

[0050] Such as figure 1 As shown, the two-stage brick-to-concrete separation process for construction waste provided in this embodiment includes the following steps:

[0051] S1, a brick-concrete sorting

[0052] The construction waste materials are sorted once to obtain the first material, the second material and the third material, and output the first material, the second material and the third material respectively;

[0053] S2, sorting

[0054] Sort the first material to remove the sundries in the first material;

[0055] S3, broken

[0056] Transport the sorted first material to the crusher for crushing:

[0057] S4, screening

[0058] The crushed first material is transported to the first screening device for screening to obtain muck, the first coarse material and the first fine material, and output the first fine material;

[0059] S5, secondary sorting

[0060] The first fine material is transported to the first flotation device for secondary separation to obtain...

Example Embodiment

[0065] Example two

[0066] The two-stage brick-to-concrete separation process of construction waste provided in this embodiment, on the basis of the first embodiment, provides a preferred process of brick-to-concrete separation in step S1, which is specifically as follows.

[0067] The step S1 specifically includes the following steps:

[0068] S1-1, transport the construction waste raw materials to the grate feeder, separate the third material through the grate gap of the grate feeder, and output the unseparated mixture of the first material and the second material:

[0069] S1-2, convey the unseparated mixture of the first material and the second material to the brick-concrete separator, implement the brick-concrete separation, and obtain the separated first material and the second material;

[0070] S1-3, crushing and removing iron from the separated first material: crushing the separated second material.

[0071] The construction waste materials can be shoveled out by an excavator a...

Example Embodiment

[0075] Example three

[0076] Example 1 shows the subsequent treatment process of the crushed first material with concrete as the main component. The two-stage brick-to-concrete separation process for construction waste provided in this example, except for those provided in Example 1 or Example 2. In addition to the process plan, it also includes the following specific process plan.

[0077] The step S4 also includes the following steps:

[0078] S4-1, returning the first coarse material to the crusher for re-crushing, and transporting it to the first screening device for screening to obtain muck, the first size coarse material and the first fine material;

[0079] S4-2, returning the coarse material of the first size to the crusher for re-crushing, and transporting it to the first screening device for screening to obtain muck, the coarse material of the second size and the first fine material;

[0080] S4-3: Return the coarse material of the second size to the crusher for re-crushing,...

Abstract

The invention relates to a two-time brick-concrete separating process for building wastes. The two-time brick-concrete separating process for the building wastes comprises the following steps: S1, carrying out brick-concrete separation for the first time, namely separating raw materials of building garbage for the first time to obtain first materials, second materials and third materials; S2, sorting, namely sorting the first materials to remove sundries in the first materials; S3, breaking, namely conveying the sorted first materials to a breaker and breaking the sorted first materials; S4, screening, namely conveying the broken first materials to a first screening device and screening the broken first materials to obtain muck, first rough materials and first fine materials; and S5, separating for the second time, namely conveying the first fine materials to a first flotation device, and separating the first fine materials for the second time to obtain brick materials and concrete materials. By the two-time brick-concrete separating process for the building wastes, brick and concrete in the building wastes are separated from each other, value of recycling of the concrete can be utilized to a maximum degree, and the integral utilization value of the building wastes is increased.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a two-time brick-concrete separation process for construction waste. Background technique [0002] The recycling process of construction waste is: raw material → crushing → sorting → crushing → screening → finished product. This process simply breaks construction waste from large pieces into small pieces, and cannot break the bricks and Concrete is used separately. [0003] The utilization rate and added value of the materials treated by the above processes in the prior art are low. In reality, enterprises have little profit and low enthusiasm for the treatment and utilization of construction waste, which is not conducive to environmental protection. Contents of the invention [0004] In order to overcome the above-mentioned technical problems existing in the prior art, the present invention provides a two-time brick-concrete separation process for constru...
