Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and more specifically to an environmentally friendly recycling device for waste steel bars from building demolition. Background Technology

[0002] Environmentally friendly building demolition waste steel bar recycling devices are widely used in the field of construction waste treatment, greatly improving the efficiency of steel bar recycling and resource reuse rate, and playing an important role in promoting green demolition and circular economy construction.

[0003] The main structure of an environmentally friendly building demolition waste steel bar recycling device typically includes a mechanical body (consisting of a base, rotating platform, telescopic arm, gripping mechanism, and crushing head, enabling flexible multi-angle operation), a hydraulic drive system, an intelligent identification and control system, and a multi-functional end-of-life processing module. The end-of-life processing module is equipped with specialized tools such as gripping clamps, hydraulic shears, crushing devices, and conveyor belts according to actual working conditions. These components work together to automate tasks such as identification and positioning of waste steel bars, gripping and sorting, cutting and crushing, and conveying and collecting. This method is characterized by high efficiency, low energy consumption, and environmental friendliness. However, the above-mentioned working method still has the following shortcomings: 1. Existing... 1. The equipment requires manual cleaning of concrete blocks from the surface of the reinforcing bars, or the pretreatment and crushing processes are operated independently. If the concrete is not stripped before entering the crushing unit, it will lead to increased wear on the crushing rollers. Moreover, the reinforcing bars will contain concrete residue after crushing, requiring secondary sorting, which reduces efficiency and does not meet the core requirements of "environmentally friendly and efficient". 2. The pretreatment unit and the sorting unit are usually driven by independent motors, and their speed and frequency are not linked. When the pretreated material enters the screening, if the pretreatment rhythm is faster than the screening speed, it is easy to cause screen blockage. 3. The dust collection of the existing equipment is prone to blockage after long-term operation, requiring shutdown to replace or clean the filter screen, which reduces work efficiency.

A nozzle adjusting rod 16 is located below the first cleaning roller brush 14, and a first filter plate 17 is located below the nozzle adjusting rod 16. The pretreatment box 11... A crushing box 2 is located at the bottom right side of the pretreatment box 11. A dust collection mechanism 3 is located on the front and rear sides of the crushing box 2. A dust collection box 31 is located in the middle of the dust collection mechanism 3. A sorting mechanism 4 is located at the bottom left side of the pretreatment box 11. A sorting box 41 is located in the middle of the sorting mechanism 4. The pretreatment box 11 is used to pre-treat the materials for subsequent crushing and processing, while reducing dust pollution. A water circulation mechanism is used to ensure the water demand for pretreatment and reduce water waste. The crushing box 2 is used to process the steel bars, while the dust collection mechanism 3 collects the dust generated during the process.

[0027] Reference Figure 1 , Figure 2 and 4 The pretreatment box 11 has two adjustment slots 111 on its front side. The top inner side of the feed inlet 12 is provided with a horizontal nozzle 122. The top of the horizontal nozzle 122 is provided with a protective plate 121. The right side of the feed inlet 12 is provided with two first water inlets 123. Two pre-pressure rollers 112 are distributed inside the pretreatment box 11. The side of the pre-pressure roller 112 is provided with four bidirectional spiral pressure strips 1121. The front side of the first cleaning roller brush 14 is provided with a cam 141. The outer side of the cam 141 is provided with a linkage rod 142. The bottom of the linkage rod 142 is movably connected to the top of the first filter plate 17. The top of the first filter plate 17 is provided with a filter plate nozzle 171.

[0028] The protective plate 121 protects the transverse nozzle 122 to prevent damage during feeding. The first water inlet 123 is connected to the water supply port 133 through a pipeline to ensure water supply during processing. The four bidirectional spiral pressure strips 1121 on the side of the pre-pressure roller 112 ensure sufficient pretreatment of the steel bars and remove residual large concrete blocks. Through the combined action of the linkage rod 142 and the cam 141, the pretreated concrete blocks are filtered and the steel bars are guided to the sorting mechanism for subsequent processing. The filter plate nozzle 171 ensures the cleanliness of the surface of the first filter plate 17 and prevents concrete accumulation.

[0029] Reference Figure 4The front side of the second cleaning roller brush 15 is fixedly connected to the first drive wheel 151, and the outer side of the first drive wheel 151 is provided with the first belt 1511. The front side of the first drive wheel 151 is fixedly connected to the second drive wheel 152.

By adjusting the fixing nuts 161, the angle of the flushing nozzle 163 can be adjusted as needed, thereby adjusting according to the feeding amount to ensure the best flushing effect on the surface of the steel bar. The power is transmitted to the sorting mechanism below through the first belt 1511 to ensure the linkage operation between the two.

[0030] Reference Figure 3 and Figure 7 A water supply base plate 131 is provided on the left side of the water supply mechanism 13. A water inlet 133 is provided on the top of the water supply mechanism 13. A water inlet 132 is provided on the bottom of the water supply mechanism 13. A water supply main shaft 135 is provided on the front side of the water supply mechanism 13. A water supply drive wheel 134 is provided on the outside of the water supply main shaft 135. A bevel gear 1341 is provided inside the water supply drive wheel 134. A water supply belt 137 is provided on the outside of the water supply drive wheel 134. Six first slots 1351 are opened on the side of the water supply main shaft 135. Two first springs 1353 are provided inside the first slots 1351. A bevel block 1352 is provided on the top of the first springs 1353. A flywheel 136 is provided at the front end of the water supply main shaft 135.

[0031] Power is transmitted to the water supply mechanism 13 via the water supply belt 137, thereby ensuring the coordinated operation of the equipment. At the same time, through the one-way power transmission between the inclined block 1352 and the water supply drive wheel 134, the water supply mechanism 13 can run for a period of time under the action of the flywheel 136 after the water supply belt 137 stops working, thereby preventing the leakage of internal dust.

[0032] Reference Figure 2 and Figure 6 The crushing box 2 has dust collection ports 21 on both the front and rear sides. The crushing box 2 is equipped with a first crushing roller 22 and a second crushing roller 23 below the first crushing roller 22. A conveyor belt 24 is installed at the bottom of the first crushing roller 22. A second belt 241 is installed on the front side of the conveyor belt 24. A steel bar collection box 25 is installed on the right side of the conveyor belt 24. The dust generated by the two crushing rollers during operation enters the dust collection box 31 through the dust collection ports 21. The crushed steel bars are transported to the steel bar collection box 25 through the conveyor belt 24.

[0033] Reference Figure 5The dust collection box 31 has an air inlet 311 inside, an air guide plate 312 inside the right side of the dust collection box 31, a balance port 313 at the top of the dust collection box 31, a dust collection bracket 32 ​​at the rear of the dust collection box 31, a first motor 321 at the top of the dust collection bracket 32, a filter drive roller 322 connected inside the first motor 321, two filter drive rollers 322, a dust collection filter 323 outside the filter drive roller 322, a fan fixing plate 324 inside the dust collection filter 323, two dust collection fans 3241 on the front side of the fan fixing plate 324, a dust collection box 33 inside the dust collection box 31, a movable plate 331 on the right side of the dust collection box 33, and a first filter 332 at the top of the dust collection box 33.

[0034] The dust generated inside the crushing box 2 is sent into the dust collection box 33 by the dust collection fan 3241. The dust is first preliminarily adsorbed and filtered by the dust collection filter 323. As the dust collection filter 323 is running, when the dust-containing side of the dust collection filter 323 rotates to the other side of the dust collection fan 3241, it is automatically blown off by the wind and enters the dust collection box 33 through the air guide plate 312. The balance port 313 is used to balance the internal and external pressure to ensure the normal operation of the equipment. The dust collection box 33 can be pulled out for cleaning after it is full.

[0035] Reference Figure 2 and Figure 6 The sorting box 41 has a coarse aggregate collection box 411 on the left side, a fine aggregate collection box 412 below the coarse aggregate collection box 411, a water collection box 42 on the right side of the fine aggregate collection box 412, a circulation pipe port 421 on the front side of the water collection box 42, a circulation filter screen 43 on the top of the water collection box 42, a filter screen scraper 432 on the left side of the circulation filter screen 43, a third belt 431 on the rear side of the circulation filter screen 43, and a sorting bucket 44 above the circulation filter screen 43.

[0036] The circulating filter 43 filters the wastewater generated above and simultaneously conveys it to the left. The filter scraper 432 cleans the filtered aggregate on the circulating filter 43 to ensure subsequent filtration operations. The filtered water is collected in the water collection tank 42 and supplied to the water inlet 132 through the circulation pipe 421, thereby completing the water circulation operation and reducing water waste.

[0037] Reference Figure 6The sorting bin 44 is equipped with a magnet fixing frame 441 inside. The front and rear sides of the magnet fixing frame 441 are fixedly connected to the inner side of the sorting box 41. Three sector-shaped permanent magnets 442 are fixedly connected to the left side of the magnet fixing frame 441. A second filter plate 413 is provided on the left side of the sorting bin 44. A third filter plate 414 is provided below the sorting bin 44. A cleaning scraper 45 is provided on the right side of the sorting bin 44. Four second springs 451 are provided on the top of the cleaning scraper 45. A first fixing plate 452 is provided on the top of the second springs 451. A material guide plate 443 is provided on the top of the sorting bin 44. The right side of the material guide plate 443 is fixedly connected to the inner side of the sorting box 41. The right side of the cleaning scraper 45 is movably connected to the inner side of the sorting box 41.

[0038] Since the right side of the magnet fixing frame 441 is not equipped with a sector permanent magnet 442, when the sorting barrel 44 drives the steel bar to rotate through this area, the steel bar will fall off due to the weakening of the magnetic force. At the same time, combined with the action of the cleaning scraper 45, the steel bar on the sorting barrel 44 is successfully detached and sent to the next processing unit through the third filter plate 414.

[0039] The working principle of this invention: In the pretreatment stage, after the device is started, the two pre-pressure rollers 112 inside the device rotate, driving the first cleaning roller brush 14 and the second cleaning roller brush 15 below them. Then, the second drive wheel 152 at the end of the second cleaning roller brush 15 transmits power to the water supply mechanism 13, causing the water supply mechanism 13 to supply water stored in the water collection tank 42 to various locations. Through the supply of water by the water supply mechanism 13, two rows of horizontal spray nozzles 122 set on the top of the pretreatment tank 11 form a water curtain at the top of the feed inlet 12, preventing dust generated during the pretreatment process from spreading outward. During the feeding process, the water curtain formed by the two rows of horizontal spray nozzles 122 at the top of the feed inlet 12 is also affected. The protective plate 121 protects the transverse nozzle 122 to prevent concrete blocks from damaging the nozzle 122 and thus affecting dust suppression. The remaining concrete blocks are broken up by two pre-compression rollers 112. The cleaning action of the first cleaning roller 14 and the second cleaning roller 15 further cleans the concrete residue on the surface of the pre-compression roller 112 and the surface of the reinforcing steel. Combined with the flushing nozzle 163 on the nozzle adjusting rod 16 to rinse the surface of the reinforcing steel, the concrete residue is removed to the greatest extent. The pre-treated reinforcing steel and concrete blocks are concentrated above the sorting bin 44 by the action of the first filter plate 17 and the material guide plate 443 for sorting operation.

[0040] During the sorting stage, the sorting bin 44 is driven by the first belt 1511 to synchronously adjust the amount of pre-processed steel bars to avoid accumulation. The steel bars are attracted by three fan-shaped permanent magnets 442 fixed inside the sorting bin 44 and not rotating with the sorting bin 44. The rotation of the sorting bin 44 rotates the steel bars to the right cleaning scraper 45. Under the combined action of weakened magnetic force and cleaning scraper 45, the steel bars fall onto the third filter plate 414, while larger pieces of concrete fall onto the coarse aggregate collection box 411 through the left second filter plate 413, completing the sorting operation.

[0041] During the water filtration process, fine debris and wastewater generated in the pretreatment stage fall onto the lowest circulating filter screen 43 under gravity. The circulating filter screen 43 filters out the fine aggregate in the water, and the filtered water flows into the collection tank 42 for subsequent recycling. Simultaneously, driven by the third belt 431, the filter scraper 432 scrapes off the fine aggregate from the circulating filter screen 43, which is then collected by the fine aggregate collection box 412. The system needs to be stopped to replace or clean the filter screen.

[0042] In the fine processing stage, the sorted steel bars are further cut as needed by the first crushing roller 22 and the second crushing roller 23, and the processed steel bars are transported into the steel bar collection box 25 by the bottom conveyor belt 24.

[0043] During the synchronous dust collection stage, while the fine processing stage is underway, the dust collection mechanisms 3 located on both sides of the crushing box 2 are activated simultaneously. Through the action of the dust collection fan 3241, the dust generated in the crushing box 2 is sucked into the dust collection box 31 through the air inlet 311. The dust is filtered and adsorbed by the dust collection filter 323 on the side closer to the crushing box 2. The dust collection filter 323 is driven by the first motor 321 to continuously change position. When the side with adsorbed dust moves to the side away from the crushing box 2, the dust on the filter is automatically blown off by the dust collection fan 3241. The dust is then concentrated inside the dust collection box 33 by the guiding action of the air guide plate 312.
