[0002] Construction waste refers to the garbage generated after the demolition and renovation of old concrete houses, such as concrete blocks, sand and gravel blocks, etc. In order to improve environmental protection requirements, some usable construction waste is usually required to be recycled and processed by crushing. Since the obtained construction waste mixed materials will contain some iron materials, the iron materials will have an adverse effect on the performance of recycled composite admixtures, so the iron removal device will be used to remove the iron materials in the construction waste mixed materials.

[0003] A Chinese utility model (publication number: CN220328949U) discloses an iron removal device for preparing recycled composite admixture using construction waste, including a material transmission mechanism support frame, a first conveyor belt, an array of iron-absorbing components, an iron-collecting pipeline, a first motor, an iron-absorbing actuator component and a control box; the iron-absorbing actuator component includes a plurality of connecting seats fixed to the top of the inner wall of the iron-absorbing component, a second transmission mounting frame connected to the connecting seats, a transition roller, an active roller and a driven roller arranged on the second transmission mounting frame, a second belt sleeved on the transition roller, the active roller and the driven roller, and an iron-absorbing device arranged at the bottom of the second transmission mounting frame. The utility model arranges a first conveyor belt to transmit the mixed material of the construction waste, and uses an array of iron-absorbing components and an iron-absorbing actuator component to absorb the iron material in the mixed material and discharge it into the iron-collecting pipeline.

[0004] In the process of realizing the above-mentioned utility model, since the iron-absorbing actuator is located at the top of the inner wall of the iron-absorbing assembly, the iron-absorbing device is located above the first conveyor belt used to transmit the construction waste mixed material, the iron-absorbing device absorbs the iron material on the first conveyor belt and moves it to the iron collecting pipe along with the second belt. The inventor found that there are at least the following problems in this technology. This iron removal method will result in that when there is a large amount of mixed material on the first conveyor belt, the iron material buried at the bottom of the mixed material cannot be removed well, and iron material may be missed. Therefore, a iron removal device for preparing recycled composite admixtures using construction waste is now proposed. Utility Model Content

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Please refer to Figure 1 and Figure 2 A deironing device for preparing recycled composite admixture using construction waste comprises a deironing equipment shell 1, and a deironing mechanism 6 installed on the top of the inner wall of the deironing equipment shell 1 for removing iron materials, and a spreading mechanism 3 installed on the front side below the deironing mechanism 6 for adjusting the thickness of the construction waste mixed material. The spreading mechanism 3 is arranged between the deironing mechanism 6 and the inclined plate 8, which can spread the construction waste mixed material put into the deironing equipment shell 1 and reduce the thickness of the construction waste mixed material.

[0034] Among them, an inclined plate 28 for discharging the construction waste mixed material is arranged below the paving mechanism 3, and one side of the inclined plate 28 is connected to the mixed material discharge port 4, an inclined plate 1 7 for discharging iron material is arranged at the rear side below the iron removal mechanism 6, and one side of the inclined plate 1 7 is connected to the iron material discharge port 5, and a feed port 2 for inputting the construction waste mixed material is arranged on the top side of the iron removal equipment shell 1. After the construction waste mixed material is input into the iron removal equipment shell 1 through the feed port 2, it falls on the inclined plate 2 8. The inclined plates 1 7 and 2 8 can make the materials above them slide backward under the action of gravity and fall into the iron material discharge port 5 and the mixed material discharge port 4 respectively. The iron material is discharged from the iron material discharge port 5 along the inclined plate 1 7, and the remaining materials are discharged from the mixed material discharge port 4 along the inclined plate 2 8.

[0035] Reference Figure 2 and Figure 3 The iron removal mechanism 6 includes an iron material conveyor belt 601 arranged in parallel inside the iron removal equipment shell 1, an electromagnet 602 is arranged inside the iron material conveyor belt 601, and a scraper plate 604 is installed below the iron material conveyor belt 601. The iron material reaching the bottom of the electromagnet 602 is adsorbed on the iron material conveyor belt 601 at the bottom of the electromagnet 602, so that the electromagnet 602 can fully absorb the iron material in the construction waste mixture to reduce omissions.

[0036] In addition, a scraper telescopic rod 606 is installed at the rear end of the scraper plate 604, and the end of the scraper telescopic rod 606 is connected to a scraper cylinder 605. The telescopic end of the scraper cylinder 605 is fixedly connected to the scraper telescopic rod 606. The scraper cylinder 605 provides a power source for the forward and backward movement of the scraper plate 604. The top of the scraper plate 604 and the lower end of the iron material conveyor belt 601 are located on the same horizontal plane.

[0037] In addition, conveying wheels 603 wrapped inside the iron material conveyor belt 601 are provided on the front and rear sides of the electromagnet 602, and the scraper plate 604 is moved forward and backward in the iron removal equipment shell 1 through the scraper telescopic rod 606 and the scraper cylinder 605. The scraper plate 604 moving forward and backward can scrape off the iron material adsorbed on the iron material conveyor belt 601.

[0038] Reference Figure 2 and Figure 4 The material spreading mechanism 3 includes a material spreading rod 301, and the ends of the inclined plates 1 7 and 2 8 close to the material spreading rod 301 are higher than the ends away from the material spreading rod 301. The material spreading rod 301 is located on the rear side of the vertical plane where the feed port 2 is located. A guide groove is provided at the connection between the material spreading rod 301 and the iron removal equipment shell 1, and the guide groove can play a guiding role in the lifting and lowering of the material spreading rod 301. Lifting blocks 302 are installed at the front and rear ends of the material spreading rod 301, and a connecting nut 305 is installed inside the lifting block 302. The connecting nut 305 is connected to a lifting screw rod 303. The material spreading rod 301 is lifted and moved in the iron removal equipment shell 1 through the lifting block 302, the connecting nut 305 and the lifting screw rod 303.

[0039] Among them, when the lifting screw rod 303 rotates, it can drive the lifting block 302 to move up and down through the connecting nut 305, thereby adjusting the height of the paving rod 301 and adjusting the distance between the paving rod 301 and the inclined plate 8. The distance between the paving rod 301 and the inclined plate 8 is based on a particle diameter slightly larger than that of the input construction waste mixed material.

[0040] At the same time, a fixing part 304 is arranged below the lifting block 302, and the fixing part 304 is fixed on the left and right sides of the iron removal equipment shell 1. The fixing part 304 is used to support the lifting screw rod 303. The diameter of the material laying rod 301 can be changed according to the actual feeding amount to avoid a large amount of material passing over the material laying rod 301.

[0041] The implementation principle of the utility model is as follows: after the construction waste mixed material is put into the iron removal equipment shell 1 through the feed port 2, it falls on the inclined plate 8, slides downward and gradually approaches the paving rod 301. Since the distance between the paving rod 301 and the inclined plate 8 is limited, only materials that meet the height can continue to fall. The lifting block 302 can be moved up and down by rotating the lifting screw rod 303, which drives the paving rod 301 to move up and down, and the distance between the paving rod 301 and the inclined plate 8 is adjusted. The distance between the paving rod 301 and the inclined plate 8 is slightly larger than the particle diameter of the input construction waste mixed material. In this way, the input construction waste mixed material can be spread on the inclined plate 8 in a single layer to the maximum extent. The diameter of the paving rod 301 can be changed according to the actual amount of material put in to avoid the material being too large. Most of the materials pass over the spreading rod 301, and the excess materials stay on the leftmost side of the inclined plate 8 and continue to wait, so as to achieve the leveling of the materials. The iron materials reaching the bottom of the electromagnet 602 are adsorbed on the iron material conveyor belt 601 at the bottom of the electromagnet 602, and the remaining materials are discharged from the mixed material outlet 4 along the inclined plate 28. The iron materials on the iron material conveyor belt 601 are transmitted backwards by the rotating transmission wheel 603 until the gravity of the iron materials is greater than the magnetic force between the iron materials and the electromagnet 602. At the same time, the scraper cylinder 605 can be started, and the scraper telescopic rod 606 is pulled to move backwards, driving the scraper plate 604 to move backwards to scrape off the iron materials adsorbed on the iron material conveyor belt 601, and the iron materials fall on the inclined plate 1 7, and are discharged from the iron material outlet 5 along the inclined plate 1 7.

[0042] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
