Description
Technical Field
[0001] The present invention belongs to the field of building materials, and particularly relates to an integrated instrument and working method for dust removal and cleaning of recycled aggregates from construction waste. Background Art
[0002] With the acceleration of urban development, a large amount of construction waste is generated during renovation, expansion, and demolition. Using the waste in engineering construction can not only reduce the exploitation of natural stone materials but also realize the resource utilization of construction waste, which is the main method for waste disposal.
[0003] Due to the extensive management in the processes of construction waste generation, sorting, and stacking, the aggregate surface is often covered with dust. Compared with natural aggregates, the surface of recycled aggregates is rougher. Common methods such as manual cleaning, soaking, and rinsing are inefficient, have high labor costs, and cannot effectively remove impurities such as dust and wood blocks on the surface of recycled aggregates. If the mud content and dust content of construction waste are relatively high, direct cleaning will reduce the cleaning efficiency and effect, thus affecting the performance of structures prepared using recycled aggregates. Only by performing dust removal and cleaning on recycled aggregates in sequence can the cleaning effect of recycled aggregates be improved. However, there is currently a lack of a highly efficient, easy-to-operate, and standardized instrument for dust removal and cleaning of recycled aggregates.
[0004] After retrieval, the patent document with the publication number CN221086568U discloses a water-saving cleaning device for coarse aggregates of recycled concrete, including a water filtration bin, a storage bin, a cleaning bin, a cover plate, and a sedimentation tank. The upper end of the water filtration bin is threadedly connected to the storage bin, a filter plate is fixed inside the storage bin, the cleaning bin is covered on the upper end of the storage bin, the cover plate is fixed on the upper end of the cleaning bin, and a motor is fixed at the center of the upper end of the cover plate; a sedimentation tank is also arranged outside the water filtration bin; two symmetrically distributed connecting ears are fixed on the outer circumferences of the water filtration bin and the cleaning bin, and a screw rod is movably connected between the two connecting ears on the outer circumferences of the water filtration bin and the cleaning bin that are on the same vertical line. The present invention solves the problems of excessive water consumption and increased cost during the cleaning of coarse aggregates of recycled concrete; and the problem that the coarse aggregates are heavy and inconvenient to take out after cleaning by setting a sedimentation tank, a cleaning bin, a storage bin, a water filtration bin, a screw rod, and a filter plate.
[0005] This patent document mainly performs precipitation after cleaning the coarse aggregates, and only has simple cleaning steps, which cannot guarantee the cleaning quality and efficiency of recycled aggregates. Especially when the dust content in the recycled aggregates is relatively high, the cleaning effect of the recycled aggregates is reduced, and multiple rounds of cleaning are required, reducing the cleaning efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention is an integrated instrument for dust removal and cleaning of construction waste recycled aggregate, including a device unit and a control unit.

[0027] As Figure 1 shown, an integrated instrument for dust removal and cleaning of construction waste recycled aggregates of the present invention is composed of a device unit and a control unit, wherein the device unit includes a storage module, a dust removal module and a cleaning module.
[0028] As Figure 1 and Figure 2 shown, the storage module includes a storage bin 12, a rotating cross beam 16 and a storage lifting rod 19, wherein the storage lifting rod 19 is installed in a storage column 20, and a storage filter screen 14 is arranged at the bottom of the storage bin 12; As Figure 3As shown in the figure, a crystal resonator 13 is arranged above the storage filter screen 14. The vibration of the recycled aggregate in the storage bin 12 is realized through the crystal resonator 13. A positioning convex structure 15 is arranged below to fix the position of the storage bin. The storage bin 12 is connected to the hollow collar 17 through the rotating cross beam 16. The hollow collar 17 is rotatably connected to the storage lifting rod 19. The storage bin 12 can rotate freely through the rotating cross beam 16 and the hollow collar 17. The hollow collar 17 is rotatably connected to the storage lifting rod 19. The storage bin 12 moves up or down through the storage lifting rod 19. A limit bolt 18 is arranged on the storage lifting rod 19 to limit the positions of the hollow collar 17 and the storage bin 12 on the storage lifting rod 19.
[0029] As Figure 1 and Figure 2 shown in the figure, the dust removal module includes a dust removal lifting rod 3 and a dust removal bin 5. A dust removal cross beam 1 is arranged above the dust removal lifting rod 3. The end of the dust removal cross beam 1 is connected to the dust removal bin 5. A dust removal ventilation opening 4 is arranged above the dust removal bin 5. A dust removal fan 8 is arranged in the dust removal bin 5. A dust removal filter screen 7 is arranged at the bottom of the dust removal bin 5. A dustproof cover 6 is arranged around the dust removal bin 5. A dust removal column 11 is arranged directly below the dust removal bin 5. A bearing platform 9 is arranged above the dust removal column 11. The bearing platform 9 is provided with a first groove 10, which matches the positioning convex structure 15 and is used to fix the position of the storage bin 12.
[0030] The dust removal cross beam 1 is fixedly installed on the dust removal lifting rod 3 through a fixing bolt 2.
[0031] See Figure 3 , four crystal resonators 13 are arranged above the storage filter screen 14. The vibration frequency of the crystal resonator 13 is related to the particle size of the recycled aggregate. When the particle size of the recycled aggregate is not greater than 4.75 mm, the vibration frequency of the crystal resonator 13 is 60 - 80 Hz; when the particle size of the recycled aggregate is greater than 4.75 mm, the vibration frequency of the crystal resonator 13 is 30 - 50 Hz.
[0032] The cleaning module includes a cleaning bin 21. A second groove 22 and a cleaning column 23 are arranged at the bottom of the cleaning bin 21 to fix the position of the storage bin 12 through the second groove 22. A liquid outlet 25 is arranged at the bottom of the cleaning bin 21. A piston 24 for opening or closing is arranged at the liquid outlet 25.
[0033] A filter lifting rod 26 is arranged on the right side of the cleaning bin 21. The top of the filter lifting rod 26 is connected to a filter screen cross beam 28 through a fixing ring 27. A folding filter screen 29 is arranged on the filter screen cross beam 28. An electromagnet 44 is arranged inside the folding filter screen 29. The folding filter screen 29 is located above the cleaning bin 21.
[0034] As Figure 1As shown in the figure, the control unit includes a first control unit, a second control unit, and a third control unit. The first control unit includes a rotary crossbeam control button 34, a storage lift rod up button 35, a storage lift rod down button 36, a vibration frequency knob 37, a PID controller 38, and a first motor 39. The first motor 39 is electrically connected to the hollow collar 17. The rotation direction of the first motor 39 is controlled by the rotary crossbeam control button 34 and the PID controller 38. The first motor 39 drives the hollow collar 17 to rotate around the storage lift rod 19, realizing the rotation of the storage bin 12. When the rotary crossbeam control button 34 is in the "dust removal" position, the storage bin 12 rotates above the bearing platform 9. When the rotary crossbeam control button 34 is in the "cleaning" position, the storage bin 12 rotates above the cleaning bin 21. The storage lift rod up button 35 and the storage lift rod down button 36 control the lifting of the storage lift rod 19 through a second motor, thereby driving the lifting of the storage bin 12, making it accurately located above the bearing platform 9 or above the cleaning bin 21, and restricting the position of the storage bin 12 through the first groove 10 and the second groove 22. The vibration frequency knob 37 adjusts the vibration frequency of the crystal resonator 13 according to the particle size of the recycled aggregate.
[0035] The second control unit includes a dust removal lift rod up button 30, a dust removal lift rod down button 31, a dust removal pressure adjustment button 32, a pressure reducing valve 33, and a third motor. The dust removal lift rod up button 30 and the dust removal lift rod down button 31 control the lifting of the dust removal lift rod 3 through the third motor, thereby controlling the vertical movement of the dust removal bin 5. The vibration of the recycled aggregate in the storage bin 12 is realized through the crystal resonator 13. The dust removal pressure adjustment button 32 controls the pressure of the dust removal fan 8 through the pressure reducing valve 33. During each stage of the dust removal process, when the crystal resonator 13 vibrates for 3 min to 5 min, the pressure of the dust removal fan 8 can be reduced by half.
[0036] After each vibration cycle is completed in the dust removal stage, the fan pressure is automatically halved, balancing the dust removal efficiency and energy consumption, and being more energy-efficient than traditional methods.
[0037] Sealed structure design: Double protection of the dust cover 6 and the filter screen reduces the dust emission by more than 90%, significantly improving the working environment.
[0038] The cleaning mode of the cleaning bin 21 can be controlled by the vibration of the crystal resonator 13. When the crystal resonator 13 starts to vibrate, the cleaning bin 21 is in vibratory cleaning. When the crystal resonator 13 stops vibrating, the cleaning bin 21 is in immersion cleaning.
[0039] The third control unit includes a filter lift rod up button 40, a filter lift rod down button 41, a filter screen control button 42, an electromagnetic relay 43, and a fourth motor.
[0040] The filter lifting rod up button 40 and the filter lifting rod down button 41 control the lifting of the filter lifting rod 26 through the fourth motor, thereby controlling the lifting of the filter screen cross beam 28, and further controlling the position of the folding filter screen 29. The filter screen control button 42 controls the magnetism of the electromagnet 44 by controlling the electromagnetic relay 43, thereby controlling the state of the folding filter screen 29.
[0041] The usage process of the present invention is as follows: After loading the recycled aggregate into the storage bin 12, rotate the rotating cross beam control button 34 to the "dust removal" position, control the storage bin 12 to rotate above the bearing platform 9, and lower the storage bin 12 by the storage bin lifting rod down button 36. The position of the storage bin 12 is fixed by the positioning convex structure 15 and the first groove 10. Adjust the height of the dust removal lifting rod 3 by the dust removal lifting rod down button 31, so that the dust removal bin 5 is located above the storage bin 12. Rotate the dust removal pressure adjustment button 32 to turn on the dust removal fan 8, and turn the vibration frequency knob 37 to adjust the frequency of the crystal resonator 13 in combination with the particle size of the recycled aggregate. After the crystal resonator 13 vibrates for 3 min to 5 min, the pressure of the dust removal fan 8 can be reduced by half by the dust removal pressure adjustment button. After the dust removal is completed, press the dust removal lifting rod up button 30 to raise the position of the dust removal bin 5, and press the storage bin lifting rod up button 35 to separate the storage bin 12 from the bearing platform 9 and enter the cleaning program.
[0042] Rotate the rotating cross beam control button 34 to the "cleaning" position, control the storage bin 12 to rotate above the cleaning bin 21, and lower the storage bin 12 into the cleaning bin 21 by the storage bin lifting rod down button 36. Add cleaning liquid into the cleaning bin 21. When the crystal resonator 13 does not vibrate, the recycled aggregate is in the soaking and cleaning mode. After soaking, adjust the frequency of the crystal resonator 13 by the vibration frequency knob 37, and the recycled aggregate is in the vibrating cleaning mode. After the cleaning is completed, light substances such as wood blocks and paper scraps in the recycled aggregate float above the storage bin 12. Press the filter lifting rod down button 41 to lower the folding filter screen 29 into the storage bin 12. Press the filter screen control button 42 to control the magnetism of the electromagnet 44 through the electromagnetic relay 43 to open the folding filter screen 29, and press the filter lifting rod up button 40 to drive the folding filter screen 29 to move upward, so as to separate the light impurities in the recycled aggregate. Press the storage bin lifting rod up button 35 to raise the storage bin 12 out of the cleaning bin 21. Pull out the piston 24 to make the cleaning liquid flow out from the liquid outlet 25, and the cleaning process ends, and the cleaned recycled aggregate can be taken out.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications or equivalent replacements can still be made to the specific embodiments of the present invention, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the protection scope of the present invention.
