Abstract
Description
Technical Field
[0001] This invention patent relates to the field of construction waste pipeline transportation technology, and more specifically, to a closed dustproof device for vertical transportation of construction waste from high-rise buildings. Background Technology
[0002] With the acceleration of urbanization, high-rise buildings are becoming increasingly common in cities. The disposal of construction waste generated during the construction and demolition of high-rise buildings has become a significant issue. Traditional methods of construction waste disposal typically involve manual handling or elevator transport, which is not only inefficient but also poses safety hazards and easily leads to chaos and environmental pollution at the construction site. To improve the efficiency of construction waste disposal and reduce the impact on the construction site, vertical transport pipelines for high-rise construction waste have emerged. This pipeline system uses vertical transport to directly transport construction waste from high-rise buildings to the ground by gravity, greatly improving transportation efficiency, reducing the risks of manual handling, and also helping to maintain a clean and safe construction site.
[0003] The existing vertical transport pipeline mainly consists of main components such as floor garbage inlets, main pipelines, deceleration gates, garbage outlets, special garbage bins, and pipeline-structure connectors. The pipeline can be directly fixed to the main components of the building under construction, such as beams, columns, and walls. It is flexible in installation and can be reused multiple times. However, the existing vertical transport pipeline is not equipped with a good dust suppression device. Since construction waste generates a lot of dust, if it cannot be effectively handled, it will affect the safety of construction workers and the urban environment.
[0004] Therefore, there is an urgent need for a closed dustproof device for the vertical transportation of waste from high-rise buildings to solve the problems existing in the current technology. Summary of the Invention
[0005] In view of this, this invention patent proposes a closed dustproof device for vertical transportation of waste from high-rise buildings, aiming to solve the problem of poor dustproof effect of existing vertical transportation pipelines.
[0006] This invention patent provides a closed dustproof device for vertical transportation of construction waste from high-rise buildings, comprising: A garbage transport pipeline, wherein the garbage transport pipeline is provided with a plurality of disposal ports, the disposal ports are used for disposing of garbage, and each of the plurality of disposal ports is provided with a sealing and blocking part; The dust removal mechanism includes a dust settling section and a dust removal pipe. The dust removal pipe is located outside the garbage transport pipe, and a dust removal air duct is formed between the dust removal pipe and the garbage transport pipe. The dust settling section is fixedly connected to the dust removal pipe, and the dust removal section is used to adsorb dust in the dust removal air duct. An isolation mechanism is fixedly connected to the inner wall of the waste transport pipeline, and the isolation mechanism is located below several of the disposal ports; A spraying mechanism is located on the lower surface of the isolation mechanism and is fixedly connected to the isolation mechanism. The spraying mechanism is used to spray water mist.
[0007] Furthermore, the dust collection unit includes negative pressure adsorption pipes, vents, and fans. Several negative pressure adsorption pipes are provided, and these pipes are located on one side of the dust collection pipe and on one side of the discharge ports. Several vents are provided on the side wall of the waste transport pipe, and these vents connect the waste transport pipe and the dust collection pipe. Several fans are provided inside the dust collection pipe, and these fans are used to blow air upwards. These fans are located below the discharge ports and are fixedly connected to the side wall of the dust collection pipe.
[0008] Furthermore, the sealing and blocking part includes a first sealing plate and a second sealing plate, which are located on the downward sides of the dispensing port and are hinged to the dispensing port.
[0009] Furthermore, the isolation mechanism includes several isolation plates and torsion springs. Several of the isolation plates are hinged to the inner wall of the waste transport pipe, and a torsion spring is provided on one side of the hinge point between several of the isolation plates and the waste transport pipe.
[0010] Furthermore, the spraying mechanism includes an atomizing spray pipe, a water supply pipe, and a protective section. The atomizing spray pipe is fixedly connected to the inner wall of the waste transport pipe, and the atomizing spray pipe is located inside the protective section. The protective section is fixedly connected to the inner wall of the waste transport pipe, and the water supply pipe is fixedly connected to the atomizing spray pipe.
[0011] Furthermore, the protective part includes a protective box, a spray nozzle, and reinforcing ribs. The protective box has an internal hollow structure. The protective box has a spray nozzle facing the garbage transport pipeline. The spray direction of the atomizing spray pipe faces the spray nozzle. Several reinforcing ribs are provided inside the protective box.
[0012] Furthermore, the waste transport pipeline comprises several pipe sections.
[0013] Furthermore, it also includes a waste collection mechanism and a collection port. The collection port is located below the waste transport pipe, and the waste collection mechanism is located below the waste transport pipe. The waste collection mechanism can be removed / placed through the collection port.
[0014] Furthermore, the collection port is provided with the sealing barrier.
[0015] Compared with existing technologies, the beneficial effects of this invention patent are as follows: This invention patent constructs multiple dust control mechanisms during the vertical transportation of construction waste in high-rise buildings. The closed pipeline and dynamically sealed discharge port block the diffusion path of dust into the building environment, eliminating the risk of cross-contamination in the construction area. The isolation mechanism forms a rigid barrier below the discharge port, buffering the impact of falling waste and weakening the initial dust generation intensity. The spray mechanism is deployed at the bottom of the isolation layer, forming a water mist coverage area at the most active dust descent point, promoting the agglomeration and settling of suspended particles and suppressing secondary re-entrainment. The annular negative pressure space formed by the dust removal pipeline enveloping the transportation pipeline... By continuously sucking up fine dust that escapes into the gaps between the pipe walls, preventing it from circulating and accumulating within the shaft, this dual-pipe structure enables directional dust diversion. Combined with the deep purification by the dust suppression unit, it forms a closed-loop treatment system with zero dust discharge. The enclosed structure isolates high-concentration dust exposure, reducing occupational health risks. The buffer isolation layer simultaneously absorbs impact energy, reducing noise interference to the surrounding environment. Water consumption is optimized through targeted spray coverage, achieving dust suppression by only wetting key dust-active areas. The continuous sealed design ensures uninterrupted transportation, avoiding downtime losses caused by traditional dust removal. The overall structure extends service life by dispersing impact loads.

[0022] See Figure 1 As shown, this embodiment provides a closed dustproof device for vertical transportation of waste from high-rise buildings, including: a waste transportation pipeline 1, which has several inlets for discharging waste, and each inlet is equipped with a sealing barrier. The dust removal mechanism includes a dust settling section and a dust removal pipe 2. The dust removal pipe 2 is located outside the garbage transport pipe 1. A dust removal air duct 3 is formed between the dust removal pipe 2 and the garbage transport pipe 1. The dust settling section is fixedly connected to the dust removal pipe 2. The dust removal section is used to adsorb dust in the dust removal air duct 3. The isolation mechanism is fixedly connected to the inner wall of the waste transport pipe 1, and the isolation mechanism is located below several disposal ports; The spray mechanism is located on the lower surface of the isolation mechanism and is fixedly connected to the isolation mechanism. The spray mechanism is used to spray water mist.
[0023] In some embodiments of this application, the dust collection unit includes a negative pressure adsorption pipe 4, a vent 5, and a fan 6. Several negative pressure adsorption pipes 4 are provided, and the several negative pressure adsorption pipes 4 are opened on one side of the dust collection pipe 2. The negative pressure adsorption pipes 4 are located on one side of several inlets. Several vents 5 are opened on the side wall of the garbage transport pipe 1. The several vents 5 connect the garbage transport pipe 1 and the dust collection pipe 2. Several fans 6 are provided in the dust collection pipe 2. The several fans 6 are used to blow air upwards. The several fans 6 are located below the inlets and are fixedly connected to the side wall of the dust collection pipe 2.
[0024] Specifically, the garbage transport pipe 1 is located inside the dust removal pipe 2. When garbage is put into the garbage transport pipe 1 through the inlet, the atomized water sprayed by the spraying mechanism first reduces dust pollution. However, the spraying mechanism cannot completely remove dust. Therefore, several ventilation openings 5 are opened on the side wall of the garbage transport pipe 1. The ventilation openings 5 connect the garbage transport pipe 1 and the dust removal pipe 2. The fan 6 of the dust suppression section continuously blows air towards the top of the garbage transport pipe 1 and the dust removal pipe 2. At this time, the dust will enter the dust removal duct 3 under the action of the ventilation openings 5. Driven by the wind, the dust moves upwards. The negative pressure adsorption pipe 4 is located inside the dust removal pipe 2. Multiple negative pressure adsorption pipes 4 adsorb the dust in the dust removal duct 3 under negative pressure. Some dust does not enter the ventilation opening 5, but it will also drift upwards under the wind. It will be continuously sprayed by the spraying mechanism to continuously reduce the dust. As the dust moves upwards, it will also enter other ventilation openings 5 and be adsorbed by the negative pressure adsorption pipes 4. The negative pressure adsorption pipes 4 achieve negative pressure adsorption through an external vacuum pump or fan.
[0025] In some embodiments of this application, the sealing and blocking part includes a first sealing plate 7 and a second sealing plate 8, which are located on the downward sides of the dispensing port and are hinged to the dispensing port.
[0026] In some embodiments of this application, the isolation mechanism includes a plurality of isolation plates 9 and a torsion spring 10. The plurality of isolation plates 9 are hinged to the inner wall of the garbage transport pipe 1, and a torsion spring 10 is provided on one side of the hinge of the plurality of isolation plates 9 and the garbage transport pipe 1.
[0027] Specifically, the first sealing plate 7 and the second sealing plate 8 are used to prevent dust from overflowing through the disposal port. When it is necessary to open the first sealing plate 7 and the second sealing plate 8, they are pushed inward, that is, pushed towards the garbage transport pipe 1. At this time, one end of the first sealing plate 7 and the second sealing plate 8 is connected to the disposal port, and the other end is against the garbage transport pipe 1. This can prevent the dust removal duct 3 from affecting the disposal port. Moreover, a negative pressure adsorption pipe 4 is set above each disposal port. That is, when the first sealing plate 7 and the second sealing plate 8 are opened, the sealing plate blocks the dust removal duct 3, and the dust is blocked from moving upward. Instead, it stops on both sides of the separation between the first sealing plate 7 and the second sealing plate 8 and is then adsorbed by the negative pressure adsorption pipe 4. When the garbage is put into the garbage transport pipe 1, the garbage first falls onto the isolation plate 9. When the garbage accumulates to a certain amount, that is, when the weight of the garbage is greater than the weight that the isolation plate 9 can bear, the isolation plate 9 opens. At this time, the garbage moves downward, and the isolation plate 9 is reset under the action of the torsion spring 10.
[0028] In some embodiments of this application, the spraying mechanism includes an atomizing spray pipe 11, a water supply pipe 12, and a protective section. The atomizing spray pipe 11 is fixedly connected to the inner wall of the garbage transport pipe 1, and the atomizing spray pipe 11 is located inside the protective section. The protective section is fixedly connected to the inner wall of the garbage transport pipe 1, and the water supply pipe 12 is fixedly connected to the atomizing spray pipe 11.
[0029] In some embodiments of this application, the protective part includes a protective box 13, a spray nozzle, and reinforcing ribs. The protective box 13 has an internal hollow structure. The protective box 13 has a spray nozzle on the side facing the garbage transport pipeline 1. The spraying direction of the atomizing spray pipe 11 is facing the spray nozzle. Several reinforcing ribs are provided inside the protective box 13.
[0030] Specifically, the atomizing spray pipe 11 is located inside the protective box 13, which protects it from being hit by garbage and prevents it from being damaged. The protective box 13 is equipped with reinforcing ribs to improve the protection level of the protective box 13.
[0031] In some embodiments of this application, the waste transport pipeline 1 includes several pipe sections.
[0032] In some embodiments of this application, a waste collection mechanism 15 and a collection port 14 are also included. The collection port 14 is provided below the waste transport pipe 1. The waste collection mechanism 15 is located below the waste transport pipe 1, and the waste collection mechanism 15 can be taken out / put in through the collection port 14.
[0033] In some embodiments of this application, the collection port 14 is provided with a sealing barrier.
[0034] Specifically, the garbage that is put in will eventually move to the bottom of the garbage transport pipe 1, where a special garbage collection mechanism 15 is set up. When the garbage collection mechanism 15 is full, it is taken out through the collection port 14 and then put back in through the collection port 14. Several pipe sections are fixedly connected.
[0035] The enclosed dust control device for vertical transportation of construction waste in the above embodiments establishes multiple dust control mechanisms during the vertical transportation process. The enclosed pipeline and dynamically sealed discharge port block the diffusion path of dust into the building environment, eliminating the risk of cross-contamination in the construction area. An isolation mechanism forms a rigid barrier below the discharge port, buffering the impact of falling waste and weakening the initial dust generation intensity. A spray system located at the bottom of the isolation layer forms a water mist coverage area at the most active dust descent point, promoting the agglomeration and settling of suspended particles and suppressing secondary re-entrainment. The dust removal pipeline 2 encloses the transportation pipeline, forming an annular negative pressure space. It continuously sucks up fine dust that escapes into the gaps between the pipe walls, preventing it from circulating and accumulating in the vertical shaft. This dual-pipe structure enables directional dust diversion. Combined with the dust suppression unit for deep purification, it forms a closed-loop treatment system with zero dust discharge. The closed structure isolates high-concentration dust exposure, reducing occupational health risks. The buffer isolation layer absorbs impact energy simultaneously, reducing noise interference to the surrounding environment. Water consumption is optimized through targeted spray coverage. Only the key dust-active areas need to be moistened to achieve dust suppression. The continuous sealing design ensures uninterrupted transportation, avoiding downtime losses caused by traditional dust removal. The overall structure extends service life by dispersing impact loads.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention is also intended to include these modifications and variations.
