Description

Technical Field

[0001] This invention relates to the field of construction waste treatment, and more particularly to a low-energy construction waste resource utilization and treatment device. Background Technology

[0002] Construction waste accounts for 30%-40% of total urban solid waste. If it is not efficiently and rationally treated and utilized, it will not only occupy a large amount of land resources but also cause serious pollution to soil, water, and air due to the seepage of harmful substances and dust dispersion, exacerbating ecological and environmental pressures. Against this backdrop, the resource utilization of construction waste has become a key measure to achieve green and sustainable development in the construction industry, and the development of efficient, low-energy-consumption construction waste treatment equipment is a core element in realizing this goal. Currently, existing construction waste treatment equipment still has many technical shortcomings in practical applications, which seriously restrict the efficiency and quality of construction waste resource utilization. These shortcomings are mainly reflected in the following aspects: First, existing construction waste treatment equipment generally lacks an efficient feeding mechanism. Because construction waste is mostly in block or loose form, and the processing volume is large, hoisting equipment is needed to transport the waste to the feed inlet of the treatment equipment, or the waste must be manually dumped into the inlet at the top of the equipment, making processing inconvenient. Secondly, existing processing procedures lack effective pretreatment steps for wet construction waste with high moisture content. Concrete blocks, bricks, and other waste generated during construction often contain a large amount of moisture due to rainwater soaking and residual construction water, which increases the operating resistance of the crushing mechanism, reduces crushing efficiency, and increases the difficulty and energy consumption of wastewater treatment. Finally, in the resource recycling stage after construction waste is crushed, existing equipment struggles to achieve efficient separation and recycling of concrete and iron products. Construction waste typically contains steel bars, nails, and other iron products. Effective recycling of these iron products can enable resource reuse and prevent damage to subsequent concrete aggregate processing equipment. Therefore, we propose a low-energy construction waste resource utilization and treatment device. Summary of the Invention

[0003] Purpose of the Invention: The purpose of this invention is to provide a low-energy-consumption construction waste resource utilization and processing device. By optimizing the feeding structure design, it realizes automated feeding of construction waste, eliminating the need for traditional hoisting equipment or manual handling, significantly reducing labor and equipment input costs, solving the problems of inconvenient feeding and low efficiency of existing devices, and reducing the environmental impact of dust diffusion during the feeding process, thus improving the convenience and environmental friendliness of the overall processing flow. Another purpose of this invention is to provide the aforementioned low-energy-consumption construction waste resource utilization and processing device, which integrates a high-efficiency pretreatment module and an intelligent separation mechanism. On the one hand, it can quickly dehydrate and drain wet construction waste with high water content, reducing the operating resistance of the subsequent crushing mechanism, avoiding energy waste and reducing the difficulty of sewage treatment. On the other hand, it can accurately separate steel bars, nails, and other iron products mixed in after the construction waste is crushed, realizing the secondary recycling of iron resources and effectively avoiding wear or malfunctions caused by iron products to subsequent concrete aggregate processing equipment. Ultimately, it achieves the comprehensive goal of low energy consumption, high resource utilization rate, and high environmental protection in the construction waste processing process, providing technical support for the green and sustainable development of the construction industry.

[0008] Furthermore, the screening mechanism includes two guide frames. The left sides of the two guide frames are fixedly connected to the front right side and the rear right side of the housing, respectively. A water storage box is provided between the two guide frames. The front and rear surfaces of the water storage box are slidably connected to lifting sleeves inside the two guide frames. A screening frame is provided inside the water storage box. The front and rear surfaces of the screening frame are provided with cylinders inside the two lifting sleeves. The opposite ends of the two cylinders penetrate to the opposite sides of the two guide frames and are fixedly connected to gears. Springs are fixedly connected to the opposite sides of the lifting sleeves and the screening frame, located outside the cylinders. Connecting plates are fixedly connected to the outer walls of the two lifting sleeves, located on the opposite sides of the two guide frames.

[0009] Furthermore, L-shaped toothed plates are fixedly connected to the upper left side of each of the two guide frames facing away from each other. The L-shaped toothed plates on the same vertical plane are adapted to the gears. Racks are fixedly connected to the right side of each of the two guide frames facing away from each other. A shaft is rotatably connected to the lower inner side of the connecting plate via a rotating shaft. A disk is fixedly connected to the end of the shaft away from the guide frame.

[0013] Beneficial effects: Through the automatic lifting and feeding of the hoisting mechanism, there is no need for manual handling or external hoisting equipment. On the one hand, it reduces the labor intensity of workers and the equipment investment cost, and reduces the overall operation cost. Through the compound vibration of "left - right swing + front - back sway", the screening mechanism can efficiently dehydrate the construction waste with a high water content, so that the water is concentrated and collected in the water storage box through the mesh holes of the screening frame, effectively reducing the water content of the construction waste when it enters the crushing link. This pretreatment process can significantly reduce the running resistance of the crushing roller, avoid the reduction of crushing efficiency and motor overload caused by the adhesion of wet materials, reduce the energy consumption in the crushing link, and achieve the low - energy connection of the "pretreatment - crushing" link. Relying on the collaborative design of "intermittent conveying + magnetic adsorption + scraping off by a scraper", the recycling mechanism can complete the separation of iron products without additional separation power devices, and only through the synchronous transmission in the crushing link: the concrete blocks slide down and are recycled naturally when the conveyor belt stops, and the iron products are adsorbed by the magnetic block and accurately conveyed to the designated position by the conveyor belt and scraped off, realizing the classified recycling of "concrete aggregate - iron resources". It not only improves the secondary utilization rate of iron resources, but also avoids the wear of iron products on the subsequent concrete aggregate processing equipment, extends the equipment life, and at the same time improves the overall resource utilization efficiency of construction waste, meeting the core invention purpose of "resource utilization". All the core actions of the device are driven by a single electric motor to achieve linkage: in the recycling mechanism, one electric motor simultaneously drives the crushing roller to rotate and the conveyor belt to convey intermittently; in the hoisting mechanism, one electric motor synchronously drives two winding wheels to complete the lifting of the screening frame and the power supply for pretreatment. There is no need to configure power sources separately for crushing, conveying, lifting and other links, reducing the number and energy consumption of power devices, simplifying the device structure, reducing the equipment maintenance difficulty, and fully achieving the invention goal of "low energy consumption". The recycling mechanism's "intermittent conveying" ensures thorough separation of concrete and iron products, avoiding mixing and interference; the screening mechanism's "composite vibration + adaptive tilting discharge" ensures sufficient dehydration and precise material introduction; and the hoisting mechanism's "synchronous lifting" ensures seamless connection between feeding and pretreatment. The entire process requires no manual intervention or adjustment, forming a closed loop from feeding, pretreatment, crushing to separation and recycling, reducing process interruptions caused by human error and improving the overall operational stability and processing efficiency of the equipment.

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a low-energy construction waste resource utilization and treatment device is provided, including a recycling mechanism 1; The recycling mechanism 1 includes a housing 101. Two crushing rollers 102 are rotatably connected to the upper part of the inner rear surface of the housing 101 via a rotating shaft. The front end of the central shaft of the crushing roller 102 extends through to the front of the housing 101 and is fixedly connected to a gear 103. The outer walls of the two gears 103 are meshed with gears 104. The two gears 104 are meshed together. A transmission wheel 105 is fixedly connected to the front surface of the gear 104 located on the left side of the front surface of the housing 101. Two drive rollers 106 are rotatably connected to the lower part of the inner rear surface of the housing 101 via a rotating shaft. The outer walls of the two drive rollers 106 are connected to a conveyor belt 107 for transmission. The front end of the central shaft of the drive roller 106 located on the left side inside the housing 101 extends to the front of the housing 101 and is fixedly connected to a gear 3 108. A transmission wheel 109 is rotatably connected to the front surface of the housing 101 near the gear 3 108 via a rotating shaft. An incomplete toothed ring 110 is fixedly connected to the outer side wall of the transmission wheel 109. The outer side wall of the transmission wheel 109 and the outer side wall of the transmission wheel 105 are connected together by a transmission belt 111. A through-type discharge port 112 is provided on the left side of the housing 101, and a through-type discharge port 113 is provided on the right side of the front surface of the housing 101. Two guide plates 114 are integrally formed on the top of the housing 101, and a cover plate 4 is engaged inside the discharge port 113. A magnetic block 115 is fixedly connected inside the housing 101 and on the inner side of the conveyor belt 107. A magnetic block 116 is fixedly connected on the inner side of the transmission roller 106 located on the right side inside the housing 101. A scraper 119 is fixedly connected to the lower inner surface of the housing 101. The top of the scraper 119 is in contact with the lower side of the outer wall of the conveyor belt 107. An L-shaped bracket 117 is fixedly connected to the front surface of the housing 101 and below the two gears 104. A motor 118 is fixedly connected to the inner side of the L-shaped bracket 117. The rear end of the output shaft of the motor 118 is fixedly connected to the front surface of the gear 104 located on the right side of the front surface of the housing 101. In use, first turn on motor 118 (fixed and supported by L-shaped bracket 117). The output shaft of motor 118 drives the right gear 104 to rotate. Because the two gears 104 mesh, the left gear 104 rotates in the opposite direction. The left gear 104 drives the meshing gear 103 to rotate, which in turn causes the two crushing rollers 102 to rotate in opposite directions inside the housing 101, forming a crushing and pulverizing effect on the construction waste. Meanwhile, the transmission wheel 105 at the front end of the left gear 2 104 drives the transmission wheel 2 109 to rotate via the transmission belt 111. The incomplete toothed ring 110 on the outer side of the transmission wheel 2 109 intermittently meshes with the gear 3 108. When the incomplete toothed ring 110 meshes with the gear 3 108, the gear 3 108 drives the left transmission roller 106 to rotate, thereby causing the conveyor belt 107 (which drives around the two transmission rollers 106) to move slowly. When the incomplete toothed ring 110 disengages from the gear 3 108, the conveyor belt 107 stops moving, thus achieving "intermittent conveying". The construction waste to be crushed is guided by two guide plates 114 at the top of the shell 101 and falls between two crushing rollers 102 to be crushed. The crushed mixture (concrete fragments + iron products) falls onto the surface of the conveyor belt 107. The magnetic block 115 on the inner side of the conveyor belt 107 generates a magnetic field, which attracts the iron products in the mixture to the surface of the conveyor belt 107. Since the concrete fragments are not magnetic, they slide directly off the surface of the conveyor belt 107 when the conveyor belt 107 stops moving and are discharged and recycled through the discharge port 112. Since the iron products can be adsorbed onto the surface of the conveyor belt 107, they can move together with the intermittent transmission of the conveyor belt 107. When the conveyor belt 107 moves the adsorbed iron products to the right transmission roller 106, the inner magnetic block 116 enhances the magnetic field, ensuring that the iron products pass around the transmission roller 106 with the conveyor belt 107. When the iron products move to the bottom of the conveyor belt 107, they are removed from the conveyor belt 107 by the scraping of the scraper 119 (which contacts the bottom of the outer wall of the conveyor belt 107). At this time, the cover plate 4 is opened, and the iron products are discharged and recycled through the discharge port 113.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a screening mechanism 2 is provided to the right of the recycling mechanism 1; The screening mechanism 2 includes two guide frames 201. The left sides of the two guide frames 201 are fixedly connected to the front right side and the rear right side of the housing 101, respectively. A water storage box 202 is provided between the two guide frames 201. The front and rear surfaces of the water storage box 202 are slidably connected to lifting sleeves 203 inside the two guide frames 201. A screening frame 204 is provided inside the water storage box 202. The front and rear surfaces of the screening frame 204 are provided with cylinders 205 inside the two lifting sleeves 203. The opposite ends of the two cylinders 205 pass through the opposite sides of the two guide frames 201 and are fixedly connected to gears 206. Springs 207 are fixedly connected to the opposite sides of the lifting sleeves 203 and the screening frame 204 and outside the cylinders 205. Connecting plates 208 are fixedly connected to the outer walls of the two lifting sleeves 203 on the opposite sides of the two guide frames 201. L-shaped toothed plates 209 are fixedly connected to the upper left side of the opposite sides of the two guide frames 201. The L-shaped toothed plates 209 on the same vertical plane are adapted to gear 4 206. Racks 210 are fixedly connected to the right side of the opposite sides of the two guide frames 201. A shaft 211 is rotatably connected to the lower inner side of the connecting plate 208 through a rotating shaft. A disc 212 is fixedly connected to the end of the shaft 211 away from the guide frame 201. Multiple tooth blocks 213 are fixedly connected to the outer wall of the disc 212. The tooth blocks 213 are adapted to gear 4 206. Gear 5 214 is fixedly connected to the outer wall of the shaft 211 and located between the connecting plate 208 and the guide frame 201. Gear 5 214 meshes with the rack 210. The end of the shaft 211 away from the disc 212 passes through the interior of the water storage box 202 and is fixedly connected to the actuating cylinder 215. A cam groove 221 is provided on the outer wall of the actuating cylinder 215. An actuating column 216 is slidably connected to the inner side of the cam groove 221. A connector 217 is fixedly connected to the top of the actuating column 216. A push plate 218 is fixedly connected to the end of the connector 217 away from the actuating cylinder 215. The push plate 218 is in contact with the opposite side of the screening frame 204. Gear 6 219 is fixedly connected to the outer wall of the lifting sleeve 203 near the water storage box 202. An movable opening 220 is integrally formed on the upper inner side of the guide frame 201. Gear 6 219 and L-shaped tooth plate 209 on the same side are on the same vertical plane. The screening mechanism 2 is used for dewatering and grading wet construction waste. It needs to be used in conjunction with the hoisting mechanism 3. First, wet construction waste with high water content (such as concrete blocks and bricks soaked in rainwater) is put into the screening frame 204. Then, the hoisting mechanism 3 drives the connecting plate 208 to rise and fall along the guide frame 201. When the connecting plate 208 rises, the shaft 211 on its inner side moves upward. The gear 214 on the outer side of the shaft 211 meshes with the rack 210 on the right side of the guide frame 201. The rack 210 drives the gear 214 to rotate, which in turn makes the shaft 211 rotate synchronously. The disc 212 at one end of the shaft 211 rotates with the shaft 211. The tooth block 213 on the outer side of the disc 212 intermittently meshes with the gear 206, which drives the gear 206 to rotate in one direction and then resets, so that the screening frame 204 can swing slightly left and right. Meanwhile, the actuating cylinder 215 at the other end of the shaft 211 rotates inside the water storage box 202. The cam groove 221 on the outside of the actuating cylinder 215 drives the actuating column 216 to slide left and right. The actuating column 216 pushes the push plate 218 through the connector 217, so that the push plate 218 repeatedly pushes the screening frame 204. With the elastic reset effect of the spring 207 (sleeved on the outside of the cylinder 205, connecting the lifting sleeve 203 and the screening frame 204), the screening frame 204 swings back and forth. When the connecting plate 208 rises to the top, gear six 219 meshes with the L-shaped toothed plate 209 on the upper left of the guide frame 201. The L-shaped toothed plate 209 drives gear six 219 to rotate, causing the lifting sleeve 203 to rotate and drive the water storage box 202 to move. The opening tilts downward to the left. Utilizing the space provided by the movable opening 220, the shaft 211 can move inward to the inside of the movable opening 220 when the water storage box 202 moves, allowing the water storage box 202 to tilt normally without obstruction. At this time, the top opening of the screening frame 204 tilts to the left as well. As the tilt of the screening frame 204 gradually increases, the waste material finally passes above the guide plate 114 of the recycling mechanism 1 and enters the crushing stage. The bottom of the water storage box 202 has an interface for connecting to external pipes, which facilitates the drainage of water during the lifting and lowering process.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 11 As shown, a hoisting mechanism 3 is provided on the top of the screening mechanism 2; The hoisting mechanism 3 includes two mounting bases 301. The bottom of each mounting base 301 is fixedly connected to the top of two guide frames 201. The two mounting bases 301 are rotatably connected by a connecting rod 302 via a rotating shaft. Both ends of the connecting rod 302 pass through the two mounting bases 301 and are fixedly connected to a winding wheel 303. A traction rope 304 is fixedly connected to the outer wall of the winding wheel 303. The bottom end of the traction rope 304 is fixedly connected to the top of the connecting plate 208. An L-shaped bracket 305 is fixedly connected to the front surface of the mounting base 301 at the front end of the connecting rod 302. A motor 306 is fixedly connected to the inner side of the L-shaped bracket 305. The rear end of the output shaft of the motor 306 is fixedly connected to the front surface of the winding wheel 303 at the front end of the connecting rod 302. The hoisting mechanism 3 is used to realize the automated feeding of construction waste and the lifting drive of the screening mechanism 2, replacing the traditional manual or hoisting equipment, reducing the difficulty of feeding and energy consumption. When in use, the construction waste is first placed in the screening frame 204 (or the construction waste is directly fed to the screening frame 204 through the external auxiliary mechanism). Then, the motor 306 is started (fixed to the front mounting base 301 through the L-shaped bracket 305). The output shaft of the motor 306 drives the front winding wheel 303 to rotate. The winding wheel 303 drives the rear winding wheel 303 to rotate synchronously through the connecting rod 302. The two winding wheels 303 simultaneously wind up the traction rope 304 (the bottom end of the traction rope 304 is fixed to the top of the connecting plate 208). The traction rope 304 pulls the connecting plate 208 to slide upward along the guide frame 201, thereby driving the lifting sleeve 203, screening frame 204 and other components to rise, providing power for the vibration and tilting discharge of the screening frame 204, and driving the screening mechanism 2 from a low position to a high position to realize automatic feeding. After the screening frame 204 finishes discharging, the control motor 306 reverses, the winding wheel 303 releases the traction rope 304, and the connecting plate 208 slides down along the guide frame 201 under the action of gravity, driving the screening frame 204 to reset, so as to carry out the feeding and pretreatment of the next batch of construction waste. If it is necessary to adjust the feeding height or speed, the speed of the motor 306 can be adjusted to control the winding / unwinding speed of the winding wheel 303, so as to achieve precise control of the lifting speed of the screening frame 204 and ensure the stability of the feeding and pretreatment process.
