Description

Technical Field

[0001] This invention belongs to the field of building materials technology, and specifically relates to a waste building materials recycling and processing equipment. Background Technology

[0002] Construction waste refers to building debris generated during construction projects due to human or natural causes, including slag, excavated soil, silt, and other waste materials. These materials offer no benefit to the building itself, but are generated during the construction process and require appropriate treatment to achieve the desired project outcome. Because it is a holistic process, consideration of each stage is crucial. Current urban waste disposal methods typically involve landfilling, which wastes vast amounts of land, manpower, and resources, hindering modern energy recycling and environmental protection. Another approach is to crush all construction waste for use in brick, tile, and ceramic tile production. However, construction waste contains lightweight impurities such as wood chips, plastics, and cardboard, resulting in poor fire resistance in the produced materials. Furthermore, the presence of metal shavings within the waste, if not crushed, makes the materials brittle, impairing their usability and posing safety hazards.

[0004] Therefore, we propose a new production equipment for the recycling of waste building materials. Summary of the Invention

[0040] Considering environmental protection principles, a dust removal assembly 40 is provided above the crushing cylinder 26. The dust removal assembly 40 includes a base plate 40-1 fixed above the crushing cylinder 26, a top plate 40-2 above the base plate 40-1, multiple elastic support rods 40-6 between the base plate 40-1 and the top plate 40-2, and a corrugated cylinder 40-3 between the base plate 40-1 and the top plate 40-2. The base plate 40-1 has multiple air inlets 40-4 extending into the crushing cylinder 26, and the top plate 40-2 has an exhaust port 40-5. One-way valves are provided at the air inlets 40-4 and the exhaust ports 40-5. The top plate 40-2 also has a vertical rod 40-7 that slides through the base plate 40-1 and the crushing cylinder 26, and a gravity ball 40-8 is provided at the end of the vertical rod 40-7. The exhaust port 40-5 is connected to the dust removal pipe 42 provided on the water tank 11 through an exhaust pipe 41. When in use, the dust removal component 40 uses the vibration of the crushing cylinder 26 to move the vertical rod 40-7 up and down, thereby extracting the airflow containing a large amount of dust generated during the operation of the coarse crushing component, the metal sorting component, and the fine crushing component 43, and purifying it with water in the water tank 11, thereby reducing air pollution.

[0041] Considering that some dust particles will fall when construction waste is put into the conveyor cylinder 1, in order to facilitate their collection, the bottom of the conveyor cylinder 1 is inclined downward from both ends to the middle. The lowest position of the bottom of the conveyor cylinder 1 is provided with a slag discharge port 1-1, and a collection box 46 is provided below the slag discharge port 1-1.

[0042] The specific working principle of this invention is as follows: First, the controller 44 controls the extension of the telescopic end of the electric push rod 39, causing the receiving plate 37-1 to be in an inclined state. Then, motor one, motor two 43-5, dual-shaft motor 27, and water pump 16 are started. When motor one is working, the conveyor belt 5 is driven; when motor two 43-5 is working, the extrusion roller 43-2 begins to rotate relative to each other; when dual-shaft motor 27 is working, the beater plate 35 moves up and down; when water pump 16 is working, it draws water filtered by filter 14 and then delivers the water to housing one 17-1. The water flow impacts the fan blade one 17-5, causing the rotating rod one 17-4 to rotate. The rotating rod one 17-4 drives the rotating tube 19 to rotate through the reducer 18, and then... Water flows out from outlet 17-3 and into housing 23-4 via water supply hose 17-6. The water flow impacts the fan blade 23-8, causing the rotating rod 23-7 to rotate. Then, the water flows into the spray pipe 22 and sprays onto the conveyor chain 5. In addition, when the rotating rod 23-7 rotates, the flue gas in the conveyor cylinder 1 is discharged from the exhaust port, discharged through the discharge pipe 45 to the connector 20, and then discharged into the water through the jet nozzle 19-1 on the rotating pipe 19 for adsorption and cooling treatment.

[0043] The specific processing of construction waste is as follows: First, the construction waste is transported to the first feeding bin 3 via a conveying device. The construction waste falls onto the conveyor chain 5 inside the conveyor cylinder 1. As the conveyor chain 5 rotates, the construction waste is heated by flames sprayed from the nozzle. This process requires heating the construction waste to no less than 500 degrees Celsius and maintaining it for more than 30 seconds, causing the cardboard and plastic in the construction waste to burn or decompose. Then, the high-temperature construction waste is sprayed with water to cool it down quickly and break its structural strength. Next, the construction waste enters the crushing cylinder 26 through the second feeding bin 25 and is crushed by the beating plate 35. Common metal building materials inside are also exposed. The crushed construction waste then falls onto the receiving plate 37-1, where the electromagnet 37-2 attracts and removes the metal. Then, the construction waste is crushed again by a pair of extrusion rollers 43-2 and can be recycled for subsequent use.

[0044] It should be noted that the water in water tank 11 will be consumed in large quantities during use, and staff will need to replenish the water as needed.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
