Description

Technical Field

[0001] This utility model relates to the field of construction waste resource utilization technology, and in particular to an automatic sorting device for construction waste resource utilization. Background Technology

[0002] The construction, renovation, and expansion of buildings generate a large amount of construction waste. Randomly dumping or landfilling this waste occupies a significant amount of land. During the dumping process, some harmful substances, such as heavy metals, can seep into the soil, causing soil pollution. Other pollutants, through rainwater runoff and leaching, can enter surface and groundwater, causing water pollution. Therefore, it is necessary to sort this waste and recycle it.

[0003] However, construction waste is large in quantity and diverse in type, making it difficult to sort in a unified manner. For example, when large quantities of bricks, concrete blocks, mortar, metals, and other waste are piled together, manual sorting is labor-intensive and inefficient. Furthermore, prolonged contact with waste may have a negative impact on workers' health, making it unsuitable for situations requiring the processing of large amounts of construction waste. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, to solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic sorting device for construction waste resource utilization, which includes:

[0006] The support unit includes a fixed platform, on one side of which a support frame is mounted;

[0007] The conveying unit includes a drive roller and a cylinder, which are rotatably connected to a support frame. A conveyor belt is fitted onto the surface of the drive roller and the cylinder, and a separator strip is installed on the conveyor belt.

[0008] A screening unit includes a screening box with sieve holes. A connecting rod and a control rod are rotatably connected to the screening box. The bottom end of the connecting rod is rotatably connected to a support frame. One end of the control rod is rotatably connected to an eccentric block, and the center of the eccentric block is installed at one end of a transmission roller.

[0009] The collection unit includes a first collection box and a second collection box. Sliders are installed on both sides of the first and second collection boxes. The sliders are slidably connected in a groove opened on the support frame. A magnetic block A is installed on the front of the first collection box, and a magnetic block B is installed on the back of the second collection box.

[0010] As a preferred embodiment of the automatic sorting device for construction waste resource utilization described in this utility model, a fan and a filter screen are installed on one side of the fixed platform. The filter screen is covered at the air intake of the fan. When the fan is started, a negative pressure is formed at the dust intake, drawing light materials and air into the fixed platform. Dust and light materials are filtered through the filter screen, and air is discharged from the exhaust port of the fan.

[0011] As a preferred embodiment of the automatic sorting device for construction waste resource utilization described in this utility model, a dust extraction port is installed on the other side of the fixed platform, and a dust collection tray is provided below the dust extraction port. Light materials and dust enter the fixed platform through the dust extraction port and are collected by the dust collection tray.

[0012] As a preferred embodiment of the automatic sorting device for construction waste resource utilization described in this utility model, the cylinder is equipped with magnetic poles inside, and a sprocket is fitted at one end of the cylinder. A chain meshes with the surface of the sprocket, and the driving force is transmitted through the chain to make the two sprockets rotate. The magnetic poles are made of permanent magnet materials such as strontium ferrite permanent magnet blocks. These materials have high remanence and coercivity and can generate a stable magnetic field without electricity, so that the material is subjected to the magnetic field when passing through the cylinder.

[0013] In a preferred embodiment of the automatic sorting device for construction waste resource utilization described in this utility model, the sprocket is driven by a drive motor, which is mounted on a support frame. When the drive motor is started, it provides a rotational driving force to the sprocket.

[0014] As a preferred embodiment of the automatic sorting device for construction waste resource utilization described in this utility model, the bottom of the first collection box and the second collection box are equipped with pulleys. The slider is inserted into the groove, and the sliding of the pulley facilitates the placement and positioning of the first collection box and the second collection box.

[0015] The beneficial effects of this utility model are:

[0016] In operation, the driving force provided by the drive motor enables the conveying and screening units to operate. The screening unit sorts the waste materials by size, allowing different sized waste materials to fall onto the conveyor belt in batches. By starting the fan to extract dust, light materials and air are drawn into the fixed platform through the dust extraction port. Light materials and dust fall into the dust collection drawer. When the conveying unit transports heavy materials, the magnetic field of the magnetic poles inside the cylinder affects the attraction of metal materials such as steel bars and iron wires. Bricks, stones, and soil blocks fall directly into the second collection box. Metal materials fall into the first collection box after moving away from the cylinder area. This completes the automatic sorting of waste resources, solving the problems of high labor intensity and low efficiency of manual sorting without requiring workers to handle waste for extended periods.

[0031] Example 1

[0032] Reference Figure 1 -5, the first embodiment of this utility model, provides an automatic sorting device for construction waste resource utilization, the structure of which includes:

[0033] The support unit 100 includes a fixed platform 101, with a support frame 102 installed on one side of the fixed platform 101; a fan 1011 and a filter screen 1012 are installed on one side of the fixed platform 101, with the filter screen 1012 covering the exhaust port of the fan 1011; a dust extraction port 1013 is installed on the other side of the fixed platform 101, and a dust collection tray 1014 is provided below the dust extraction port 1013; when the fan 1011 is started, a negative pressure is formed at the dust extraction port 1013, drawing light materials and air into the fixed platform 101 through the dust extraction port 1013, filtering dust and light materials through the filter screen 1012, and exhausting the air from the exhaust port of the fan 1011, while the light materials and dust fall into the dust collection tray 1014 for unified cleaning;

[0034] The conveying unit 200 includes a drive roller 201 and a cylinder 202, which are rotatably connected to a support frame 102. A conveyor belt 203 is fitted onto the surfaces of the drive roller 201 and the cylinder 202, and a separator strip 204 is installed on the conveyor belt 203. A magnetic pole 2021 is installed inside the cylinder 202, and a sprocket 2022 is fitted onto one end of the cylinder 202. A chain 2023 is meshed onto the surface of the sprocket 2022. The sprocket 2022 is driven by a drive motor 2024, which is mounted on... On the support frame 102; start the drive motor 2024 to make the sprocket 2022 rotate, and transmit the driving force through the chain 2023 to make the two sprockets 2022 rotate, which in turn drives the transmission roller 201 and the cylinder 202 to rotate, so that the conveyor belt 203 transports the heavy materials forward. When the garbage passes through the cylinder 202, it is affected by the magnetic field of the magnetic pole 2021. Metal materials such as steel bars and iron wires are attracted, while bricks, stones and soil blocks fall directly into the second collection box 402. Metal materials fall into the first collection box 401 after moving away from the area of ​​the cylinder 202.

[0035] The screening unit 300 includes a screening box 301 with screen holes. A connecting rod 302 and a control rod 303 are rotatably connected to the screening box 301. The bottom end of the connecting rod 302 is rotatably connected to the support frame 102. One end of the control rod 303 is rotatably connected to an eccentric block 304. The center of the eccentric block 304 is installed at one end of the transmission roller 201. The rotation of the transmission roller 201 drives the eccentric block 304 to rotate, which in turn drives the end of the control rod 303 connected to the eccentric block 304 to rotate. Under the support of the connecting rod 302, the control rod 303 will drive the screening box 301 to shake, thereby screening the waste material in the screening box 301. The size of the screen holes decreases from left to right, so that waste materials of different sizes fall onto the conveyor belt 203 in batches and are separated by the separating strips 204.

[0036] The collection unit 400 includes a first collection box 401 and a second collection box 402. Slider blocks 403 are installed on both sides of the first and second collection boxes 401 and 402, respectively. The sliders 403 are slidably connected to grooves opened on the support frame 102. A magnetic block A 404 is installed on the front of the first collection box 401, and a magnetic block B 405 is installed on the back of the second collection box 402. A pulley 4011 is installed at the bottom of the first and second collection boxes 401 and 402. The slider 403 is inserted into the groove on the support frame 102, and the first collection box 401 is pushed inward. The sliding of the pulley 4011 causes the slider 403 to slide into the bottom of the groove, thus completing the installation of the first collection box 401. Similarly, the second collection box 402 is pushed between the support frames 102, causing the magnetic blocks A 404 and B 405 to attract each other, thus completing the installation of the second collection box 402.

[0037] During use, the garbage is first poured onto the screening box 301. The drive motor 2024 is started to make the sprocket 2022 rotate. The driving force is transmitted through the chain 2023, causing the two sprockets 2022 to rotate, which in turn drives the transmission roller 201 and the cylinder 202 to rotate. The rotation of the transmission roller 201 drives the eccentric block 304 to rotate, which in turn drives the end of the control rod 303 connected to the eccentric block 304 to rotate. With the support of the connecting rod 302, the control rod 303 will drive the screening box 301 to shake, thereby screening the garbage material in the screening box 301. The size of the screen holes decreases from left to right, so that garbage materials of different sizes fall onto the conveyor belt 203 in batches.

[0038] Then, the separating strips 204 on the conveyor belt 203 separate the waste, and the blower 1011 is started to create negative pressure at the dust extraction port 1013, drawing light materials and air into the fixed platform 101 through the dust extraction port 1013. The dust and light materials are filtered through the filter screen 1012, and the air is discharged from the exhaust port of the blower 1011. The light materials and dust fall into the dust collection tray 1014 for unified cleaning.

[0039] Finally, the rotation of the transmission roller 201 and the cylinder 202 causes the conveyor belt 203 to transport heavy materials forward. When the garbage passes through the cylinder 202, it is affected by the magnetic field of the magnetic pole 2021. Metal materials such as steel bars and iron wires are attracted, while bricks, stones and soil blocks fall directly into the second collection box 402. After moving away from the area of ​​the cylinder 202, the metal materials fall into the first collection box 401.

[0040] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
