Description

Technical field:

[0002] The utility model relates to a device for removing iron from construction waste aggregates. Background technology:

[0004] Applying construction waste to the production of concrete bricks can turn these construction wastes into treasures, which not only solves the problem of construction waste disposal, but also solves the problem of raw materials caused by the lack of local mountain resources to a certain extent, and improves the competitiveness of products. In addition to construction waste, waste cement slurry generated in the pipe making process of the pipe pile factory is also used to reuse cement and water resources. However, before these construction wastes are processed into concrete porous bricks, metal impurities such as iron blocks and steel bars mixed in them need to be removed. The current common iron removal method requires pouring construction waste into an iron removal device for iron removal. This method is inefficient, labor-intensive, and has poor iron removal effects.

[0005] In order to overcome this problem, Chinese patent publication number CN204769117U discloses a deironing device for construction waste, which includes a conveying mechanism and a deironing mechanism, wherein the conveying chain of the conveying mechanism is arranged around the upper conveying roller and the lower conveying roller, and the upper conveying roller is coaxially provided with a first sprocket on one side, the first sprocket is connected to the second sprocket through a transmission chain, the second sprocket is coaxially connected to the conveying motor, the deironing mechanism is arranged on the upper side of the conveying curtain, the guide roller support of the deironing mechanism is installed on the upper side of the upper support, and the deironing belt is arranged around the transmission roller and the guide roller, wherein the transmission roller is coaxially provided with a first pulley on one side, the first pulley is connected to the second pulley through a transmission belt, the second pulley is coaxially connected to the deironing motor, and the deironing motor is installed at one end of the upper support. However, although the above patent achieves the deironing effect and reduces the labor intensity, it does not directly contact with the construction waste during the entire deironing process, and some metal impurities are easily mixed in the construction waste and not adsorbed away, resulting in the deironing quality being affected. For this reason, it is necessary to improve this technical problem, and this case is born. Utility model content:

[0007] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a device for removing iron from construction waste aggregates.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a device for removing iron from construction waste aggregates, comprising a conveying mechanism for conveying construction waste aggregates, and an iron removal belt arranged above the conveying mechanism, a temporary aggregate storage cylinder with an open top is arranged below the output end of the conveying mechanism, a roller corresponding to the output end position of the conveying mechanism is arranged above the temporary aggregate storage cylinder, a plurality of groups of iron removal rod groups for contacting the construction waste aggregates are arranged on the outer surface of the roller, and a removal component for removing metal impurities adsorbed on the iron removal rod group is arranged on the side of the roller away from the conveying mechanism.

[0009] Furthermore, the roller is arranged longitudinally and driven to rotate by a de-ironing motor, and several groups of de-ironing rod groups are evenly spaced along the axial direction of the roller, each de-ironing rod group includes multiple de-ironing rods, and the multiple de-ironing rods are evenly distributed around the axis of the roller, and the de-ironing rods extend along the radial direction of the roller.

[0010] Furthermore, the iron removing rod is made of a permanent magnet.

[0011] Furthermore, the rejecting component includes a longitudinally arranged rejecting slide plate, which is inclined with the left end higher and the right end lower. The left end of the rejecting slide plate is provided with a plurality of makeshift slots evenly spaced along the longitudinal direction, and the plurality of makeshift slots correspond to the positions of a plurality of groups of de-ironing rod groups. The makeshift slots are convenient for the de-ironing rods with corresponding positions to pass through when they rotate. When the de-ironing rods pass through the makeshift slots, the metal impurities on the de-ironing rods are limited by the rejecting slide plate and separated from the de-ironing rods.

[0012] Furthermore, a collection frame for placing metal impurities sliding down along the material removing slide plate is provided directly below the lower end of the material removing slide plate.

[0013] Furthermore, the width of the relief slot is 2-5 mm larger than the diameter of the iron removal rod.

[0014] Compared with the prior art, the utility model has the following effects: the utility model has a reasonable structural design. On the basis of the original iron removal belt, a rotatable iron removal rod group is arranged on the output side of the conveying mechanism of the construction waste aggregate. During the rotation of the iron removal rod group, the iron removal rod group contacts the construction waste aggregate and absorbs the metal impurities mixed therein. The double iron removal is combined to effectively improve the iron removal effect on the construction waste aggregate. Description of the drawings:

[0021] like Figures 1-2 As shown, the utility model is a device for removing iron from construction waste aggregates, comprising an existing conveying mechanism 1 for conveying construction waste aggregates, and an iron removal belt 2 arranged above the conveying mechanism, specifically: an aggregate temporary storage cylinder 3 with an open top is arranged below the output end of the conveying mechanism 1, and the construction waste aggregates fall from top to bottom into the aggregate temporary storage cylinder 3, and the aggregate temporary storage cylinder 3 is used to temporarily store the construction waste aggregates output by the conveying mechanism; a roller 4 corresponding to the output end position of the conveying mechanism 1 is arranged above the aggregate temporary storage cylinder 3, and a plurality of groups of iron removal rod groups 5 are arranged on the outer surface of the roller 4, and the iron removal rod groups 5 are in contact with the construction waste aggregates falling from top to bottom, and the iron removal rod groups 5 use magnetic force to absorb metal impurities mixed in the construction waste aggregates, and a removal component 6 for removing metal impurities adsorbed on the iron removal rod group is arranged on the side of the roller 4 away from the conveying mechanism 1. On the basis of the original iron removal belt, a rotatable iron removal rod group is arranged on the output side of the conveying mechanism of the construction waste aggregate. The iron removal rod group contacts the construction waste aggregate during rotation and adsorbs the metal impurities mixed in it. The double iron removal is combined to effectively improve the iron removal effect of the construction waste aggregate.

[0022] It should be noted that the conveying mechanism for conveying construction waste aggregates and the iron removal belt arranged above the conveying mechanism are both based on existing technologies. For example, Chinese Patent Publication No. CN204769117U discloses an iron removal device for construction waste. This embodiment is improved on the basis of the existing technology, specifically: newly adding aggregate temporary storage cylinder, roller, iron removal rod group and removal assembly and other structures.

When the de-iron rods 8 pass through the make way slots 10, the metal impurities on the de-iron rods are limited by the rejecting slide plate and separated from the de-iron rods, thereby achieving the removal of the metal impurities on the de-iron rods, and then the metal impurities slide down along the rejecting slide plate.

[0027] In this embodiment, a collecting frame 11 is provided directly below the lower end of the ejecting slide plate 9, and the collecting frame is used to place the metal impurities sliding down along the ejecting slide plate.
