Asbestos Finishing Materials Removing Apparatus}

The present invention relates to an asbestos finishing material demolition apparatus, and more particularly, to remove asbestos dust when scattering the asbestos finishing material installed on the indoor ceiling of a building, to protect workers from asbestos dust, and to work wet. The present invention relates to an asbestos finish demolition device that facilitates work.

Asbestos is widely used as a building material, especially as a finishing material because of its low price, excellent bonding with other materials, excellent mechanical strength, excellent incombustibility, durability, insulation, and thermal insulation.

However, inhalation of asbestos dust for a long time is known to cause asbestos lung (pulmonary necrosis), lung cancer and the like. Therefore, workers dealing with asbestos often suffer from asbestos lungs or die from lung cancer. In particular, asbestos dust during the demolition of buildings causes serious problems, and the disposal of the removed asbestos also requires attention.

Due to problems in the removal of asbestos, domestic law stipulates many laws. In particular, the Industrial Health Regulations (Labor Decree No. 308) must isolate the place where asbestos is used from other places of work (art. 227), and keep it moist while working (art. 231). In case of asbestos dismantling and removal, the place should be sealed, wetted and maintained at negative pressure (Article 239), and the waste must be sealed after being sealed in an impermeable container or bag, etc. Article 240), and the provision of preventing asbestos dust from scattering (Article 241).

In addition, in order to transport the removed asbestos waste, asbestos should be sprayed with an absorbent such as moisture absorbent to prevent dust from being generated and a containment agent to prevent dust from being released to the outside.

Currently, in order to remove asbestos, workers should wear work clothes and gas masks that completely block the body and the outside of the worker. However, these measures do not completely protect workers from asbestos dust. In addition, the asbestos dust is scattered in the work space where asbestos is removed, worker's work clothes, various equipment required for asbestos removal, and may later threaten the health of workers and others.

The present invention has been made to overcome the above-mentioned problems, when removing the asbestos finishing material installed on the ceiling of the building, asbestos dust is not scattered and protects the workers from asbestos dust and work so as to work To facilitate the purpose.

In order to achieve the above object, the present invention is an apparatus for removing the asbestos finishing material installed on the indoor ceiling of the building, which is open to the upper side, the upper edge is in close contact with the indoor ceiling; A support for supporting a work space from an indoor floor of the building; A glove protruding into the working space part on at least one side of the working space part and allowing an external worker to work in the working space part by inserting a hand; A water supply unit installed inside the work space to supply water to the work space; And it is installed on the other side of the work space, and provides an asbestos finish dismantling device comprising a finish outlet opening sized to discharge the asbestos finish from the inside of the work space to the outside.

It is provided inside the working space portion further comprises a drug injection unit for injecting a wetting agent or a containment agent into the working space portion, or the water injection unit is capable of spraying water mixed with the wetting agent or the containment agent.

It is preferable to further include a barrier that can block the finish outlet. The blocking door may be open to the outside of the work space and preferably has a pressing portion made of an elastic material for pressing the closing door to close.

The container may further include a container fixing part for fixing a waste container or a bag for storing the finish material discharged through the finish material discharge port, and blocking the inside of the waste container or bag from outside air.

The support may further include an elevating unit for elevating the work space, an answer plate located on the side, and a wheel located below the operator.

According to the present invention described above, since the worker works to remove the asbestos finish of the ceiling of the building in the closed working space using gloves, the worker and the surrounding environment can be protected from asbestos dust. The contaminated air and water in the working space can be purified by the air intake and the water intake and discharged or recycled to the outside. Cleaning of the removed asbestos finish with water and spraying of medicaments such as absorbents, containment agents and the like can be done in the working space. Treated asbestos finishes are transferred to waste containers through finish outlets, and the opportunity to contact the outside environment is blocked. In addition, the lifting unit, the answer plate, the wheel, the receiving unit and the like can be easily operated by the operator.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention. Further configurations and effects of the present invention will be described more clearly below.

1 is an overall perspective view of an asbestos finishing material demolition apparatus according to the present invention.

Referring to FIG. 1, a work space 12 is formed on an upper portion of the asbestos finishing material demolition apparatus 10 according to the present invention. The working space 12 is cut off inside and outside except for the open upper side, and a close contact 14 is formed at the upper edge of the working space 12. The close contact portion 14 is a part that is in close contact with the indoor ceiling of the building when the asbestos finishing material dismantling work, and blocks the inside and outside of the work space 12. Thus, when the close contact portion 14 is in close contact with the indoor ceiling of the building, the interior of the work space 12 is isolated from the outside. Thus, the asbestos dust inside the working space 12 is not discharged to the outside.

Water is accumulated in the lower portion of the work space 12. Water is supplied using a water injector 20 or the like to be described later. Asbestos dust is scattered from the ceiling when nails or screws are removed and asbestos finish is removed from the ceiling to demolish the asbestos finish from the interior ceiling of the building. Absorbed by water accumulated in the lower portion 12. In order for the asbestos dust to flow into the work space 12 without being scattered into the space above the ceiling, the inside of the work space 12 must be maintained at a negative pressure, which is described below. And by the air purification system 44.

A pair of gloves 16 are attached to at least one side of the work space 12. The glove 16 is installed to protrude into the work space 12, and a worker may fit his or her hand and arm to the glove 16 from the outside of the work space 12. The glove 16 isolates the worker's hand and arm from the work space 12. The worker proceeds with asbestos finish removal work in the working space 12 using the glove (16). The pair of gloves 16 is preferably movable left and right to adjust the interval according to the body shape of the operator. It is preferable that a pair of gloves 16 are provided on a plurality of side surfaces of the work space 12 so that a plurality of workers can work in cooperation.

The transparent window 18 is installed above the glove 16 at the side of the work space 12. The worker can work while wearing the gloves 16 while looking inside the work space 12 using the transparent window 18.

The water injector 20 for spraying water into the work space 12 is installed inside the work space 12. The water injector 20 is used to supply water that collects in the lower portion of the work space 12. In addition, the water injector 20 keeps the interior of the working space 12 in a wet state. Then, the water injector 20 is used to remove the asbestos dust from the asbestos finish surface by spraying water with the asbestos finish (W) that the operator removed from the indoor ceiling of the building (see Figure 2). Meanwhile, although FIG. 1 and FIG. 2 illustrate the washing of the asbestos finish material W by spraying water through the water injector 20, the work space part is supplied by supplying water into the work space part 12 in another manner. (12) It is also possible to provide a space in which water accumulates, and to immerse the asbestos finish in a space where water accumulates.

The water injector 20 may spray together not only water but also drugs such as a humectant and a containment agent. The wetting agent causes the removed asbestos finish to contain moisture, reducing the generation of dust from the asbestos finish. The containment agent coats the surface of the removed asbestos finish to reduce dust emissions. Alternatively, in addition to the water injector 20, an injector (not shown) for injecting a drug such as a humectant or a sequestrant may be separately provided. In this case, there is an advantage that the removal of asbestos dust using water and the post-treatment using chemicals can be selected according to the situation, but the space inside the piping and working space 12 is complicated.

The treated asbestos finish is treated as waste and discharged to the outside through a finish outlet 22 installed on the side of the work space 12. The finish outlet 22 is located on the side where the gloves 16 and the transparent window 18 are not installed so as not to disturb the operator.

Referring to the cross-sectional view of FIG. 3, the finish outlet 22 is opened and closed by a blocking door 24. The blocking door 24 may be opened outward, and the pressing part 26 of an elastic material such as a spring attached to the blocking door 24 presses the closing door 24 to close. When the worker works in the work space 12, the pressurizing portion 26 closes the blocking door 24 so that the asbestos dust inside the work space 12 is not discharged to the outside. When the worker pushes the asbestos finish (W) toward the finish discharge port 22, the door 24 is opened and can discharge the asbestos finish (W) to the outside.

Outside the finish outlet 22 is a container or bag (C) for receiving asbestos finish (W) is located. The container or bag (C) is an impervious container or bag as defined in Article 240 of the Regulation on Industrial Health Standards. The container or bag (C) is a container or bag (B) when the asbestos finishing material (W) is transported and disposed of. C) Do not scatter asbestos dust from inside to outside. That is, according to the present invention, the asbestos finishing material W removed from the ceiling and processed in the work space 12 is immediately received in the container or bag C without an intermediate process.

Around the outside of the finish discharge port 22 is provided with a container fixing portion 28 for fixing the container or bag (C) in close contact with the outer wall of the working space (12). The inlet of the container or bag C is fitted in the container holder 28 to isolate the internal space of the container or bag C from the outside. Thus, asbestos dust is prevented from being scattered from the asbestos finishing material accommodated in the inner space of the container or bag C, and that asbestos dust inside the working space 12 is scattered to the outside even though it is discharged through the finish material outlet 22. Is prevented

Referring back to FIG. 1, the work space 12 is connected with an air suction hose 30, a water suction hose 32, and a water supply hose 34. The air suction hose 30 is a hose for sucking air in the work space 12, and the water suction hose 32 is a hose for sucking water accumulated in the lower part of the work space 12. The supply hose 34 is a hose for supplying water to the water injector 20. Details of the operation of the air intake hose 30, the water intake hose 32 and the water supply hose 34 will be described later.

The working space 12 is supported by the support 36.

In FIG. 1, the lifting unit 38 is illustrated in a structure in which the height of the working space 12 is manually adjusted and then fixed with screws or pins. Alternatively, the lift unit 38 may be driven using a motor, a hydraulic pump, or the like.

The support plate 36 is provided with a response plate 40 on which the worker 16 can stand on the side where the glove 16 and the transparent window 18 are located. After the worker climbs up the answer plate 40, the worker puts his hands and arms on the gloves 16 and checks the inside of the work space 12 with the transparent window 18. The answer plate 40 is detachable from the support 36.

It is preferable that the wheel 42 is installed at the lower part of the support 36 in contact with the building floor. Using the wheel 42, the worker can work while moving the asbestos finishing material demolition apparatus 10. In order to fix the position of the asbestos finish dismantling device 10 during the work, it is preferable that the wheel 42 is further provided with a brake device.

The air purification system 44 is installed below the support 36. The air purification system 44 sucks air in the work space 12 through the air suction hose 30 by using an internal pump (not shown), and uses the internal filter (not shown) to draw air. Purify and discharge the purified air through the blowing fan 46. The air purification system 44 removes asbestos dust contained in the air inside the work space 12 to prevent the accumulation of asbestos dust in the work space, the worker's work clothes, various equipment required for asbestos removal, and the like. In addition, the air purification system 44 sucks air in the work space 12 to maintain the inside of the work space 12 at a negative pressure (Article 239, Article 3 of the "Rules on Industrial Health Standards"). Reference). Thus, asbestos dust generated from the ceiling is introduced into the working space 12.

The water purification system 48 is installed below the support 36. 4 shows an internal configuration of the water purification system 48.

1 and 4, water accumulated in the work space 12 is introduced into the water purification system 48 through the water suction hose 32. Water accumulated in the work space 12 is contaminated, including asbestos dust, and water introduced into the water purification system 48 is purified through the purification filter 50 in the water purification system 48. The purification filter 50 may be configured in multiple stages as necessary. The final stage of the multi-stage purification filter 50 is preferably composed of a high efficiency particulate air (HEPA) filter capable of removing fine dust. The water purified through the purification filter 50 may be pressurized by the pump 52 and supplied to the water injector 20 through the water supply hose 34.

Alternatively, the pump 52 may pressurize clean water supplied by an external tap water to supply the water injector 20. Water passing through the pump 52 may be discharged to the external waste water storage tank. When a medicament such as a humectant or a sequestrant is supplied to the water injector 20 together with water, a pipe for adding a humectant, a sequestrant or the like to purified water or externally supplied water may be provided. The water purification system 48 of FIG. 4 has been shown to be capable of selecting and operating the aforementioned functions.

On the other hand, when a medicament, such as a humectant, a containment agent, is supplied separately from water, a device for supplying a medicament, such as a humectant, a containment agent, may be provided separately from the water purification system 48.

On the other hand, although the air purification system 44 and the water purification system 48 are shown to be fixed to the support 36, they may be installed separately from the support 36. Although the air purification system 44 and the water purification system 48 are preferably fixed to the support 36 and can be moved simultaneously, the support (depending on the volume and weight of the air purification system 44 and the water purification system 48) It may not be fixed to 36).
