Description

Technical Field

[0001] This invention belongs to the field of construction waste treatment technology, specifically relating to a green and environmentally friendly construction waste recycling device. Background Technology

[0002] With the acceleration of industrialization and urbanization, the construction industry has also developed rapidly, resulting in an increasing amount of construction waste. Construction waste refers to the slag, waste soil, waste materials, silt, and other waste generated by construction units or individuals during the construction, laying, demolition, and repair of various buildings, structures, pipelines, etc. If it is not treated and reused in a timely manner, it will inevitably have adverse effects on society, the environment, and resources. Among them, the dust in construction waste will become dust in subsequent garbage sorting, exacerbating the air pollution problem in the process of urban construction. At the same time, there are still many recyclable and useful materials in construction waste. With proper treatment, resources can be saved. Currently, a lot of garbage is directly discarded, and a lot of resources are wasted. Some garbage can be recycled, but the later processing is complicated and the workload is large.

[0003] The document with authorization announcement number CN212943301U discloses a dust removal and crushing equipment for construction waste, including a crushing device and a dust removal device. The dust removal device includes an induced draft fan, a blower, a dust collection box, atomizing nozzles, and a water tank. When the induced draft fan is turned on, dust is blown into a filter cover. Simultaneously, the blower is turned on, and the suction generated by the blower draws dust from the crushing box through the filter cover into the dust collection box. The atomizing nozzles inside the dust collection box can wet and clean the dust absorbed from the crushing box. The collection box, with its loading and unloading ports, is slidably positioned within the recycling area.

[0004] However, due to the complex composition of construction waste, directly crushing it all increases the difficulty of subsequent screening and separation, resulting in low efficiency and high economic costs. Summary of the Invention

Detailed Implementation Example

[0029] This embodiment provides a green and environmentally friendly construction waste recycling device, as shown in the attached figure. Figure 1 As shown, it includes a base 1, a main housing 21 mounted on the base 1, a feed inlet 22 and a water inlet pipe 23 mounted on the upper end of the main housing 21, a water outlet pipe 24 mounted on the lower end of the main housing 21, a retrieval component 31 mounted on the upper end of the interior of the main housing 21, a retrieval port 32 mounted on the side wall of the main housing 21, a retrieval box 33 mounted on the side end of the main housing 21 and communicating with the retrieval port 32, an adsorption component 41 mounted on the lower end of the retrieval component, an opening 42 mounted on the side wall of the main housing 21, and a stripping box 43 mounted on the side end of the main housing 21 and communicating with the opening 42.

[0030] In this embodiment, as shown in the appendix Figure 2As shown, the salvage component 31 includes an equipment box 311 disposed on the upper side wall of the main box 21, a motor 312 disposed on the side end of the equipment box 311, a drive rod 313 rotatably disposed in the equipment box 311 and connected to the motor 312, a main gear 314 disposed on the drive rod 313, two rotating rods 315 distributed on both sides of the drive rod 313 and rotatably connected to the equipment box 311, and two auxiliary gears 316 respectively disposed on the two rotating rods 315 and meshing with the main gear 314. The rotating rods 315 extend into the main box 21, and a salvage plate 317 is disposed on the rotating rods 315. Among them, two auxiliary gears 316 are distributed and mesh with the two sides of the main gear 314. The main gear 314 drives the two auxiliary gears 316 to rotate in the same direction and speed. Finally, the two auxiliary gears 316 drive the two rotating rods 315 to rotate, thereby driving the salvage plate 317 to strike the water surface and send the lightweight material floating on the water surface into the salvage box 33.

[0031] In this embodiment, as shown in the appendix Figure 3 As shown, the retrieval box 33 includes a retrieval box body 331, a screen plate 332 disposed inside the retrieval box body 331 and located at the lower end of the retrieval port 32, and a water outlet 333 disposed at the bottom of the retrieval box body 331.

[0032] In this embodiment, the salvage component 31 and the salvage box 33 cooperate to inject water into the main tank 21 through the water inlet pipe 23. When the water level reaches the lower end of the salvage port 32, the lower end of the salvage plate 317 strikes the water surface, sending the lightweight material floating on the water along with the water through the salvage port 32 into the salvage box 33. The lightweight material is intercepted by the screen plate 332, and the water passes through the screen plate 332 and is discharged from the salvage box body 331 through the outlet 33 for recycling. The water level in the main tank 21 is controlled by the flow rate valve 242 on the water inlet pipe 23 and the water outlet pipe 24 to ensure that the water level remains stable.

[0033] In this embodiment, as shown in the appendix Figure 4 Appendix Figure 5 and appendix Figure 6As shown, the adsorption component 41 includes a fixing rod 411, a plurality of magnetic vertical plates 412 disposed on the fixing rod 411, a sealing plate 413 disposed at the end of the fixing rod 411 and located outside the opening 42, a control rod 414 disposed on the sealing plate 413 and extending to the outside of the unloading box 43, and a push plate 415 disposed at the end of the control rod 414; there are two control rods 414 symmetrically disposed on both sides of the sealing plate 413, and the two control rods 414 are provided with protrusions 416 on their side ends, and the two protrusions 416 are slidably connected to two grooves 439 opened on the side walls of the unloading box. The magnetic vertical plates 412 are of the same size, parallel to each other and spaced apart, and are used to adsorb magnetic materials that fall onto the adsorption component 41, and the two sides of all the magnetic vertical plates 412 are connected and fixed by the fixing rod 411. The sealing plate 413 is made of non-magnetic material, located inside the unloading box 43, and is used to seal the opening 42 to prevent water leakage. If necessary, a sealing strip can be provided on the surface of the sealing plate 43 to secure the connection between the sealing plate 413 and the opening 42. The two control rods 414 are also located inside the unloading box 43 and can be pulled out of the unloading box 43 by the operator pulling the push plate 415 from the outside. The sliding connection between the protrusion 416 and the groove 439 serves to improve the stability of the adsorption component 41 and to provide support for the fixed rod 411 and the magnetic vertical plate 412 structure located inside the main box 21, ensuring that the magnetic vertical plate 412 remains vertical and increasing the effective adsorption area. The other end of the fixed rod 411 away from the sealing plate 413 is provided with an identical sealing plate, and the distance between the two sealing plates is less than or equal to the width of the main box 21 and less than or equal to the width of the unloading box 43.

[0034] In this embodiment, as shown in the appendix Figure 7 and attached Figure 8As shown, the stripping box 43 includes a stripping box body 431, an air outlet pipe 432 disposed at the upper end of the interior of the stripping box body 431, multiple nozzles 433 disposed on the air outlet pipe 432, a fan 434 disposed on the outer side wall of the stripping box body 431, an air inlet pipe 435 for connecting the air outlet pipe 432 and the fan, a receiving box 436 disposed at the bottom end of the interior of the stripping box body 431, a first discharge port 437 disposed on the side end of the stripping box body 431, and a vertical sealing plate 438 disposed on the side end of the receiving box 436 and extending to the outer end of the stripping box body 431. The vertical sealing plate 438 is provided with a handle 438a. The functions of the fan 434, the air outlet pipe 432, and the nozzles 433 are twofold: first, to blow away the magnetic material adsorbed on the adsorption component 41; and second, to dry the magnetic material. The receiving box 436 is used to receive the blown magnetic material, and after receiving the magnetic material, the handle 438a is operated to move the receiving box 436 from the first discharge port 437 out of the unloading box body 431 to transfer the collected magnetic material.

[0035] In this embodiment, the adsorption component 41 and the dewatering box 43 cooperate. First, the lever 438a is operated to place the fixing rod 411, i.e., the magnetic vertical plate 412, inside the main box 21, and the sealing plate 413 blocks the opening 42. After water is supplied to the preset water level by the inlet pipe 23, the sinking magnetic material is adsorbed onto the magnetic vertical plate 412 as it passes through it, and the remaining material continues to settle to the bottom of the main box 21. After the material has settled, the outlet pipe 24 discharges and collects the water, and a filter screen 241 is installed on it to prevent the settled material from being discharged with the water. The lever 438a is operated to pull the fixing rod 411, i.e., the magnetic vertical plate 412, out of the main box 21, and all the magnetic vertical plates 412 are located inside the dewatering box body 431. The high-speed gas sprayed from the nozzle 433 blows off the magnetic material adsorbed by the magnetic vertical plates 412, and it is collected in the receiving box 436 at the lower end.

[0036] In this embodiment, as shown in the appendix Figure 2 As shown, it also includes a heating box 61 disposed on the same side of the retrieval box body 331 and the unloading box body 431, a heating plate 62 disposed inside the heating box 61, and a control panel 63 disposed on the outer wall of the heating box 61. The height of the heating box 61 covers the entire side of the retrieval box body 331 and the unloading box body 431, and is used to heat the retrieval box body 331 and the unloading box body 431. Its functions are twofold: first, to dry the retrieved lightweight materials and magnetic substances inside the retrieval box body 331 and the unloading box body 431; and second, to reduce the magnetism of the magnetic vertical plate 412 inside the unloading box body 431, thereby facilitating the nozzle 433 to quickly blow the magnetic substances off.

[0037] In this embodiment, as shown in the appendix Figure 9 As shown, the system also includes a support plate 51 located on the inner wall of the main housing 21 and above the outlet pipe 24; a filter box 52 mounted on the support plate 51; a filter screen 53 mounted on the bottom plate of the filter box 52; a second discharge port 54 located on the side wall of the main housing 21 and above the support plate 51; and a sealing door 55 hinged to the outer wall of the main housing 21 for closing the second discharge port 54. The filter box 52 collects substances that settle into the main housing 21. The second discharge port 54 is used to remove the filter box 52 from the second discharge port 54 after the water in the main housing 21 has been drained, thereby collecting the settled substances. The sealing door 55 is equipped with a plug 551 that connects to the outer wall of the main housing 21 to enhance the connection strength between the sealing door 55 and the main housing 21, thereby effectively sealing the second discharge port 54 and preventing leakage.

[0038] In this embodiment, as shown in the appendix Figure 1 As shown, the base 1 is also provided with a placement plate 11 for placing the filter box 52.

[0039] The working principle of this invention is as follows: Water is filled into the main tank 21 to a preset water level, and the water level is maintained in balance through the inlet pipe 23 and outlet pipe 24. Construction waste is then fed into the main tank 21 through the inlet 22. A large amount of dust enters the water and is adsorbed. Lighter materials in the waste are first screened by the buoyancy of the water and sent to the retrieval box 33 via the retrieval component 31. The settled waste is screened by the adsorption component 41 within the main tank 21, and magnetic materials are adsorbed and fixed by the magnetic vertical plate 412. Finally, the waste settles to the bottom of the main tank 21 and is collected by the filter box 52. After all the water is drained, the adsorption component 41 is transferred to the unloading box 43. Simultaneously, the blower 434 and heating plate 62 are activated to remove moisture from the materials in the retrieval box 33 and the unloading box 43, while the magnetic materials are blown into the receiving box 436 for collection.

[0040] The advantage of this invention lies in avoiding dust generation during the screening process by soaking construction waste in water. Simultaneously, it can quickly separate lightweight materials, magnetic substances, and sediment from the construction waste, especially the high-value magnetic substances, thus increasing its economic value. Compared to traditional equipment that requires crushing and separating all construction waste, this invention's process of first separating the waste, then classifying, crushing, and recycling it significantly improves work efficiency and offers advantages such as ease of operation and high economic benefits.
