Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a construction waste sorting and recycling device. Background Technology

[0002] Construction waste refers to building debris generated during construction projects due to human or natural causes. Its composition is complex, primarily consisting of sand and gravel, concrete bricks, and metal blocks. Sand and gravel, as a crucial component of basic building materials, have considerable reuse value. After screening and processing, they can be used for road paving, concrete preparation, and other projects. Concrete bricks, through crushing and screening, can be transformed into recycled aggregates for reuse in the construction industry, achieving resource recycling. Metal blocks themselves have high recycling value; through recycling and smelting processes, they can be remanufactured into various metal products, reducing the need for mining primary metal resources.

[0003] However, existing construction waste collection and transportation equipment on the market has significant functional limitations, failing to effectively separate different types of construction waste. During the collection, transportation, and processing of construction waste, sand, gravel, concrete bricks, and metal blocks are often mixed together, forming a chaotic mixture. This mixed state poses significant challenges to subsequent construction waste treatment and reuse. On the one hand, the mixed construction waste increases the difficulty of processing, requiring more manpower, resources, and time for secondary sorting, leading to a substantial increase in processing costs. On the other hand, due to the varying physical and chemical properties of different components of construction waste, mixed processing may affect the quality of recycled products, reduce their reuse value, and even prevent the effective recycling and utilization of some valuable resources, resulting in serious resource waste. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a construction waste sorting and recycling device. This design effectively solves the problem that existing waste recycling devices have low efficiency in sorting and processing construction waste and are difficult to maximize the recycling and utilization of resources.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a fixed frame, on which a material distribution box is fixedly connected. The material distribution box contains a first material cavity and a second material cavity, with a partition plate between the first and second material cavities. A material distribution frame is located above the first material cavity and is fixedly connected to the material distribution box. A screening box is connected below the first material cavity, and a first hopper is connected below the screening box.

Both the first and second hoppers are fixedly connected to the fixed frame. A third hopper is fixedly connected to the fixed frame, and an electromagnetic iron removal component is located on the third hopper above the material distribution frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see the appendix Figure 1-5 This embodiment discloses a construction waste sorting and recycling device, comprising a fixed frame 1, a sorting box 2 fixedly connected to the fixed frame 1, a first material chamber 201 and a second material chamber 202 inside the sorting box 2, a partition plate 203 between the first material chamber 201 and the second material chamber 202, a sorting rack 3 above the first material chamber 201, the sorting rack 3 being fixedly connected to the sorting box 2, a screening box 4 connected below the first material chamber 201, a first hopper 5 connected below the screening box 4, a second hopper 6 connected to the side of the screening box 4, the second hopper 6 being connected above the second material chamber 202, both the first hopper 5 and the second hopper 6 being fixedly connected to the fixed frame 1, a third hopper 7 fixedly connected to the fixed frame 1, an electromagnetic iron removal component 8 on the third hopper 7, the electromagnetic iron removal component 8 being located above the sorting rack 3.

[0021] The fixed frame 1 is constructed from multiple welded square steel bars. A horizontal support platform is welded to the upper end of the fixed frame 1. The distribution box 2 is bolted to the fixed frame 1. The distribution box 2 is an open shell structure without a top or cover. The top of the distribution box 2 is used to receive construction waste. The interior of the distribution box 2 is divided into a first material chamber 201 and a second material chamber 202. Above the first material chamber 201 is a distribution frame 3. When construction waste enters the distribution box 2 from the top, larger pieces of construction waste slide down the distribution frame 3 into the second material chamber 202 under the action of the distribution frame 3, while smaller pieces of construction waste fall through the gaps in the distribution frame 3 into the screening box 4 below. The construction waste in the screening box 4 is then processed by the two... After screening, the construction waste is separated into the first hopper 5 and the second hopper 6. The second hopper 6 has two connection ports: one on the side for connecting to the screening box and the other on the top surface for connecting to the second material chamber 202. The first hopper 5 is used to collect small particles of waste such as sand and gravel, while the second hopper 6 is used to collect large pieces of waste such as concrete bricks. An electromagnetic iron removal component 8 is installed above the material distribution frame 3. When the metal blocks roll to the left with the material distribution frame 3, they are attracted by the electromagnetic iron removal component 8 and adhere to it. The metal blocks are then transported by the electromagnetic iron removal component 8 to the third hopper 7.

[0022] The electromagnetic iron removal assembly 8 contains an iron separator 501, which mainly consists of an excitation coil, a screen, a cooling system, and a vibration system. When current is applied, a magnetic pole is generated at the center of the excitation coil, magnetizing the stainless steel screen; the magnetic field strength can reach 10,000-30,000 GS. When a metal object passes through the induction coil of the electromagnetic iron separator 501, under the action of the alternating electromagnetic field, the magnetic metal object is attracted to the area below the electromagnetic iron separator 501. After approximately 3 seconds, an electric trolley on the iron separator 501 transports the extractor to the material recovery box. The electromagnet is demagnetized to lower the metal plate, and the electric trolley brings the extractor back above the conveyor belt. When the electromagnetic separator 501 releases iron, it receives a signal from the metal detector and immediately returns to the upper part of the belt, waiting for the next metal object to be sucked in before releasing it. The separator 501 is existing technology, and this application does not improve the separator 501. It simply uses the principle of the separator 501 adsorbing iron blocks to screen iron blocks in construction waste. The separator 501 is supported on the outside by a lifting frame 502. Four lifting legs are installed under the lifting frame 502. Two of the lifting legs are installed on the fixed frame 1, and the other two are installed on the distribution box 2. The lifting legs are hydraulic telescopic rods. The distance between the lifting frame 502 and the separator 501 and the distribution frame 3 can be adjusted by the lifting legs. When the bricks on the distribution frame 3 are large, the lifting frame 502 is raised; when the bricks are small, the lifting frame 502 is lowered. To prevent interference between the lifting frame 502 and the distribution box 2, a groove 9 is opened on one side of the distribution frame 3.

[0023] The support rods 301 on the sorting rack 3 are horizontally mounted above the partition plate 203. Each support rod 301 has multiple cylindrical rods 302 inclined at 20° welded to its side wall. The ends of the cylindrical rods 302 are welded and fixed to the inner wall of the sorting box 2. The multiple cylindrical rods 302 form a grid-like flow guide structure, which allows the waste materials on the sorting rack 3 to be sorted and processed more quickly.

[0024] The bottom of the first material chamber 201 is connected to the screening box 4. A screen plate 10 is installed at a 30° angle inside the screening box 4. The bottom outlet of the screening box 4 is connected to the first hopper 5, and its side wall outlet is connected to the second hopper 6. The first hopper 5 and the second hopper 6 are both welded to the fixed frame 1. The discharge ports 11 of the first hopper 5 and the second hopper 6 face the front side of the fixed frame 1. In order to make the first hopper 5 and the second hopper 6 discharge material to the discharge port 11 more quickly, the inside of the first hopper 5 and the second hopper 6 has a smooth inclined surface that cleans towards the discharge port 11, reducing their own coefficient of friction.

[0025] Furthermore, in order to improve the screening efficiency of the screen plate 10 in the screening box 4, the screen plate 10 can be replaced by a vibrating screen, so that the fixed screen plate 10 becomes a vibrating screen. This can avoid the clogging of the screen holes and improve the screening efficiency. Vibrating screens are widely used in life and belong to existing technology, so they will not be introduced in detail here.

[0026] The overall workflow of this utility model is as follows: Construction waste is fed into the distribution frame 3 from above the distribution box 2. Small particles fall into the first material chamber 201 through the gap of the cylindrical rod 302, while large particles roll into the second material chamber 202. After the material in the first material chamber 201 enters the screening box 4, small-diameter crushed material falls into the first hopper 5 through the screen plate 10, and the remaining material enters the second hopper 6 from the side wall. Large particles in the second material chamber 202 fall directly into the second hopper 6, while ferromagnetic materials are adsorbed by the iron remover 501 when passing through the distribution frame 3.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
