Background

In the treatment of building decoration garbage, various garbage with different volumes, different qualities, different purposes, different properties, different densities and the like need to be sorted. Generally, since construction and decoration garbage contains a large amount of foamed concrete, and the foamed concrete is incombustible and can be reused as raw materials or auxiliary materials of other construction materials, the most common method in construction and decoration garbage is to sort the unusable garbage such as sand, formwork, ironwork, steel bar, rag, paper, plastic and the like in the construction aggregate from the recyclable aggregate such as foamed concrete by various methods such as water separation, air separation, magnetic separation, vibration and the like. However, since the foamed concrete contains a large amount of bubbles and has a low density, it is difficult to separate and sort light impurities such as paper sheets, rags, plastic sheets, wood chips and the like from the foamed concrete, which hinders the recycling of the foamed concrete.

In order to solve the problems, the foamed concrete is crushed by utilizing the characteristic of high brittleness of the foamed concrete, and then the foamed concrete is subjected to water separation. The volume ratio of bubbles in each foamed concrete particle is reduced, the density of the foamed concrete particle is increased compared with that of foamed concrete, namely, the foamed concrete particle can sink in water, and light substance impurities mixed in the foamed concrete are separated by utilizing the buoyancy of the water. Thus, it is required that, in crushing the foamed concrete, the foamed concrete is merely crushed, and unusable light impurities such as gravel, formwork, ironwork, reinforcing steel, rag, paper, plastic, etc. mixed in the foamed concrete cannot be crushed.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

As shown in fig. 1, the utility model provides a foamed concrete selects separately crushing roller, establish cylinder roller 11 on roller 12 including roller 12 and cover, the roller surface of cylinder roller 11 sets up to the smooth surface. The roll surface of the cylindrical roll 11 is wavy along the axial direction thereof.

Among the above-mentioned technical scheme, the roll surface that utilizes cylinder roller 11 sets up to the smooth surface, does not tear the closed angle, when carrying out the breakage to the concrete, because the fragility of foaming concrete, the crushing roller of this structure only extrudees the breakage to foaming concrete hard material like this, but because light material impurity has plastic deformation's ability, when light material impurity passes through between two crushing rollers, by two crushing rollers extrusion, only its physical form can change or the fracture appears, but can not take place the breakage and the floating ability that the crushing condition kept light material impurity. That is, the crushing roller of the present construction has the ability to selectively crush compared to a cylindrical roller or a toothed roller.

As shown in fig. 1, at least two limiting grooves 14 are formed in the inner circumferential surface of the cylindrical roller 11, the limiting grooves 14 are parallel to the axis and penetrate through two ends of the cylindrical roller 11, positioning blocks 13 corresponding to the limiting grooves 14 are arranged on the outer circumferential surface of the roller shaft 12, and the positioning blocks 13 are in transition fit with the limiting grooves 14. With cylinder roller 11 and roller 12 separately set up, be convenient for change when the circumstances such as wearing and tearing take place in the crushing work for a long time at cylinder roller 11, save the cost.

The first embodiment is as follows:

as shown in fig. 2, the wavy roll surface of the cylindrical roll 11 is formed by alternately arranging semicircular convex arc surfaces 111 and non-variable-diameter cylindrical arc surfaces 112, and the semicircular convex arc surfaces 111 and the non-variable-diameter cylindrical arc surfaces 112 are smoothly connected.

Example two:

as shown in fig. 3, the wavy roll surface of the cylindrical roll 21 is formed by alternately arranging semi-circular convex arc surfaces 211 and semi-circular concave arc surfaces 212, and the semi-circular convex arc surfaces 211 and the semi-circular concave arc surfaces 212 are smoothly connected.

Example three:

as shown in fig. 4, the wavy roll surface of the cylindrical roll 31 is formed by alternately arranging minor arc convex arc surfaces 311 and minor arc concave arc surfaces 312, and the minor arc convex arc surfaces 311 and the minor arc concave arc surfaces 312 are smoothly connected.

Example four:

as shown in fig. 5, the wavy roll surface of the cylindrical roll 41 is formed by alternate semicircular convex arc surfaces 411 and inferior arc concave arc surfaces 412, and the semicircular convex arc surfaces 411 and the inferior arc concave arc surfaces 412 are smoothly connected.
