[0002] With the acceleration of the urbanization process, the construction industry has developed vigorously, and at the same time, a large amount of waste building materials have been generated. Among these waste building materials, some such as plastics and pipes have certain recyclable value. However, the current treatment of these recyclable waste building materials still faces many challenges.

[0003] Traditional waste building material recycling devices have obvious deficiencies in grading and screening. Their screen designs are often relatively single and cannot achieve multi-stage fine screening, resulting in uneven particle size distribution of the screened materials and making it difficult to meet the requirements of subsequent different processing technologies for the particle size of the materials. At the same time, traditional recycling devices have poor effects in removing iron filings. Due to the lack of an effective magnetic separation device, metal substances, especially iron wires and iron filings, in waste building materials are difficult to be fully separated, which not only affects the purity of the recycled materials but also may damage subsequent processing equipment, reducing the recycling efficiency and resource utilization rate.

The screening assembly is arranged in the screening chamber 4 to screen and classify the crushed materials. The screening assembly includes two layers of inclined screens 5. The aperture of the upper screen 5 is larger than that of the lower screen 5. An oscillating motor 14 is fixedly arranged at the bottom of both screens 5. A magnetic separation device is also included. The magnetic separation device is arranged in the screening chamber 4 and above the screen 5 to separate metal substances in the waste building materials. The magnetic separation device includes a rectangular frame 7 fixedly arranged inside the screening chamber 4. A strong magnet array 8 is fixedly arranged inside the rectangular frame 7. The strong magnet array 8 is composed of several electromagnets arranged in a corrugated shape.

[0029] A waste building material resource recycling device further includes a dust suction device. The dust suction device includes a dust collector 10 fixedly arranged outside the screening chamber 4. The dust suction port of the dust collector 10 extends into the crushing chamber 2 and the screening chamber 4 through a dust suction pipe 6.

[0031] The working principle of the waste building material resource recycling device of the present utility model is as follows: This waste building material resource recycling device mainly relies on the coordinated action of functions such as crushing, screening, and magnetic separation to achieve the effective recycling of waste building materials. Waste building materials are first fed into the crushing chamber from the feed hopper. The crushing assembly (double-roll crusher) crushes them, breaking large pieces of materials into smaller particles. The crushed materials fall into the screening chamber and are screened and classified on two layers of inclined screens with different apertures. The aperture of the upper screen is larger, which is used to screen out materials with larger particles; the aperture of the lower screen is smaller, further screening out finer particles. The oscillating motor at the bottom of the screen provides vibration to promote the rapid screening of materials. At the same time, the magnetic separation device (strong magnet array inside the rectangular frame) above the screen uses the magnetic field generated by the electromagnets to adsorb metal substances in the materials, achieving metal separation. The dust suction device absorbs the generated dust through the dust collector and the dust suction pipe during the operation of the device to keep the working environment clean.

[0032] The specific use process of the waste building material resource recycling device of the present utility model is as follows:

[0033] 1. Before starting the equipment, comprehensively check the status of each component, including the feeding hopper 1, crushing chamber 2, screening chamber 4, screen 5, magnetic separation device, dust collection device, etc., to ensure no faults and unobstructed discharge ports. At the same time, confirm that the electromagnet is in the demagnetized state.

[0034] 2. Pour the waste building materials into the feeding hopper 1, and the materials will naturally slide into the crushing chamber 2 by gravity.

[0035] 3. Start the crushing component 3, and the two rollers of the double-roll crusher rotate relative to each other to efficiently crush the incoming waste building materials.

[0036] 4. After the crushed materials fall into the screening chamber 4, first start the magnetic separation device. The strong magnet array 8 composed of electromagnets bent in a corrugated shape starts to be magnetized, generating a strong magnetic field to fully adsorb metal substances such as iron wires and iron filings in the materials, significantly improving the purity of the recycled materials and reducing the adverse effects of metal impurities on subsequent processing.

[0037] 5. After magnetic separation is completed, the materials are screened. They fall on the upper screen 5. At this time, the oscillating motor 14 operates to drive the screen 5 to vibrate. The materials with larger particles slide along the inclined direction of the upper screen and are discharged from the discharge port one 9 at the lower end of the inclination.

[0038] 6. The smaller particles of the materials pass through the sieve holes of the upper screen and fall onto the lower screen for screening again. The fine particle materials that meet the aperture of the lower screen are discharged from its discharge port one 9 at the lower end of the inclination.

[0039] 7. The dust collection device operates synchronously. The vacuum cleaner 10 sucks in the dust generated during the crushing and screening processes through the dust collection pipe 6.

[0040] 8. When the metal substances adsorbed on the electromagnet accumulate to a certain extent, control the electromagnet to demagnetize to facilitate the removal of the adsorbed iron filings.

[0041] 9. The finest materials passing through the two-layer screen are discharged from the discharge port two 11 at the center of the bottom of the screening chamber 4.

[0042] 10. After the equipment has run for a period of time, check the working conditions of the internal components through the inspection window 12 on the front of the screening chamber, and perform maintenance and cleaning if necessary.

[0043] 11. After the work is completed, turn off the power of the equipment, clean the equipment and the surrounding environment, and classify and store the collected different materials.

[0044] The above description is about the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the gist of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
