Description

Technical Field

[0001] The utility model relates to the technical field of construction waste recycling, in particular to an iron removal device for a composite admixture used in construction waste recycling. Background Technique

[0002] Construction waste refers to the general term for muck, waste concrete, waste bricks and stones and other waste generated in the production activities of the construction industry such as demolition, construction, decoration, and repair. Classified by the source of generation, construction waste can be divided into engineering muck, decoration waste, demolition waste, engineering slurry, etc.; classified by the composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick and tile fragments, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc. Construction waste refers to the construction waste generated due to human or natural reasons during the project, including waste muck, abandoned soil, silt, and waste materials. These materials are of no help to the building itself, but are substances generated during the construction process and need to be processed accordingly in order to achieve the ideal construction project. During the pretreatment of construction waste, large-volume sundries are removed manually. However, some iron filings or small-volume iron materials cannot be completely removed. Then the remaining iron materials will enter the subsequent treatment process - roller press pre-grinding together with the construction waste. In this way, the remaining iron materials will have an adverse impact on the performance of the recycled composite admixture. Content of the Utility Model

[0019] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] As Figures 1-4As shown in the figure, a device for removing iron from a composite admixture for recycled construction waste includes four groups of support columns 1. A conveying mechanism 2 is arranged on the upper sides of the four groups of support columns 1. A mechanism 3 for removing iron is arranged at a position near the front side on the upper side of the conveying mechanism 2. The conveying mechanism 2 includes two mounting frames 21 fixedly arranged at the upper ends of the four groups of support columns 1. A connecting frame 22 is fixedly welded at a position near the rear side on the upper sides of the two mounting frames 21. A feeding hopper 23 is fixedly arranged on the upper side of the connecting frame 22. A first motor 24 is fixedly installed at a position near the lower side at the rear of the feeding hopper 23. A limiting wheel 25 is fixedly connected to the front end of the first motor 24. Baffles 26 are fixedly connected to the lower ends of the feeding hopper 23 near both sides and the rear side. A hydraulic rod 27 is fixedly installed at the rear end of one of the two mounting frames 21 near one side. Movable plates 28 are movably arranged on the upper sides of the two mounting frames 21. Activity grooves 29 are formed at positions corresponding to the two movable plates 28 on the upper sides of the two mounting frames 21. Fixed shaft frames 210 are fixedly arranged at positions near the front and rear sides at the upper ends of the two movable plates 28. Two conveying wheels 211 are movably arranged inside the four fixed shaft frames 210. A conveyor belt 212 is movably sleeved on the outer sides of the two conveying wheels 211. A second motor 213 is fixedly installed at the front side of one of the two mounting frames 21 near the other side.

[0021] In this embodiment, the limiting wheel 25 is located at a position near the lower side inside the feeding hopper 23. The three baffles 26 are located at the upper side of the conveyor belt 212. The two movable plates 28 are limited and slidably arranged inside the two activity grooves 29. One of the two movable plates 28 near one side is fixedly connected to the hydraulic rod 27. The rotating shaft of the second motor 213 penetrates through the front side position of one of the two mounting frames 21 near the other side and is fixedly connected to the front side conveying wheel 211.

[0022] Specifically, first, the raw materials of construction waste are put into the feeding hopper 23. By starting the first motor 24, the feeding hopper 23 is driven to rotate. Then, the rotating feeding hopper 23 drives the raw materials of construction waste to be fed in a limited amount, avoiding the direct accumulation of construction waste on the upper side of the conveyor belt 212 and causing damage to it. At this time, the second motor 213 is started to drive the two conveying wheels 211 and the conveyor belt 212 to rotate, and convey the raw materials forward. At the same time, the hydraulic rod 27 is started to make its telescopic rod extend and retract, thereby driving the two movable plates 28 to slide back and forth inside the two activity grooves 29. Thus, the two conveying wheels 211 and the conveyor belt 212 are driven to move back and forth through the four fixed shaft frames 210. According to the inertia of the raw materials, they are jolted to be laid flat on the upper side of the conveyor belt 212, realizing the uniform conveying of the raw materials of construction waste and making them in a flat state, avoiding mutual occlusion, facilitating the subsequent iron removal, and thus improving the iron removal efficiency.

[0023] In this embodiment, the iron removal mechanism 3 includes four support rods 31 fixedly arranged at the upper sides of the two groups of mounting frames 21. Two connecting frames 32 are fixedly arranged at the upper sides of the four support rods 31. Synchronous wheels 33 are movably arranged near both sides inside the two connecting frames 32. A synchronous belt 34 is movably sleeved outside the two synchronous wheels 33. A third motor 35 is fixedly installed at one side of the front group of the two connecting frames 32. A scraper 36 is fixedly arranged near one side inside the two connecting frames 32. A iron storage box 37 is arranged below the scraper 36. The synchronous belt 34 is magnetically set. The rotating shaft of the third motor 35 penetrates through one side of the front group of the two connecting frames 32 and is fixedly connected with one of the two synchronous wheels 33 on one side. The scraper 36 is attached to the synchronous belt 34.

[0024] Specifically, by starting the third motor 35, the two synchronous wheels 33 and the synchronous belt 34 are driven to rotate. Then, the iron filings or small-volume iron materials mixed in the construction waste raw materials are adsorbed by the rotating synchronous belt 34. When it is transported to the upper side of the iron storage box 37, it is scraped off by the scraper 36 and falls into the iron storage box 37, realizing the automatic removal of iron filings or small-volume iron materials, avoiding the remaining iron materials from entering the subsequent treatment process together with the construction waste, and thus preventing the remaining iron materials from having an adverse impact on the performance of the recycled composite admixture.

[0025] Working principle:

[0026] During use, first put the construction waste raw materials into the feeding hopper 23. By starting the first motor 24, drive the feeding hopper 23 to rotate. Then, drive the construction waste raw materials to discharge in a limited amount through the rotating feeding hopper 23, avoiding the direct accumulation of construction waste on the upper side of the conveyor belt 212 and causing damage to it. At this time, start the second motor 213 to drive the two sets of conveyor wheels 211 and the conveyor belt 212 to rotate, and convey the raw materials forward. At the same time, start the hydraulic rod 27 to make its telescopic rod extend and retract, and then drive the two sets of movable plates 28 to slide back and forth inside the two sets of movable grooves 29. Thus, drive the two sets of conveyor wheels 211 and the conveyor belt 212 to move back and forth through the four sets of fixed shaft frames 210, and make it spread flat on the upper side of the conveyor belt 212 according to the inertia jitter of the raw materials, realizing the uniform conveying of the construction waste raw materials and making them in a flat state, avoiding mutual occlusion, facilitating subsequent iron removal, and then facilitating the improvement of the iron removal efficiency. In addition, by starting the third motor 35 to drive the two sets of synchronous wheels 33 and the synchronous belt 34 to rotate, and then adsorb the iron filings or small-volume iron materials mixed in the construction waste raw materials through the rotating synchronous belt 34.
