Description

Separable asbestos collector with a flow guide formed in inlet portion}

The present invention relates to a sound pressure device, and more particularly, an upper body with a blower and a lower body with a filter unit are detachably detachable and capable of inducing fluid flow into an inlet formed at a lower end of the lower body. It relates to a sound pressure machine in which a slant is formed.

Asbestos is a type of igneous rock and is a fibrous silicate compound taken from the minerals of serpentine and hornblende in the natural world.

Asbestos is a generic term for natural mineral fiber, and it is classified into blue asbestos, brown asbestos and white asbestos. Blue asbestos and brown asbestos have been designated as prohibited substances since January 2000. White asbestos has been approved since July 1991. Permission to use it.

Exposure to asbestos is known to cause fatal diseases such as lung cancer, malignant mesothelioma, asbestos, as well as blood injuries, respiratory diseases, and incubation periods of 10 to 30 years. have.

Such asbestos has been used in many building materials because of its excellent insulation, heat resistance, insulation, good tensile strength, durability and abrasion resistance to chemical substances such as acids and alkalis, and low cost. Asbestos-based building materials are used as insulation materials for walls and ceilings and steel frameworks for decoration and heat dissipation, and as insulation for piping, ducts, boilers and hot water tanks to prevent heat transfer and condensation. Thermal system insulation (TSL), batak tiles, ceiling tiles (tex), slate, nightlights and other miscellaneous materials.

In the case of dismantling and dismantling of building materials containing such asbestos, harmful asbestos dust is scattered in a large amount and adversely affects workers and the surrounding environment.In accordance with related laws, the head of the local labor authority when dismantling and removing asbestos-using building materials is approved. The removal and removal procedures are very complex and tricky.

Looking at the process of removing the ceiling material during the removal of such asbestos, first, all the exits and walls, including windows, entrances and the like to maintain the vinyl to seal the workplace. Next, spray the humectant sufficiently before operation to prevent the asbestos dust from scattering. Thereafter, a local exhaust system (also called a negative pressure device) is used in the workplace to maintain the negative pressure so that asbestos dust in the workplace does not leak to the outside. After that, the ceiling material is removed so as not to be crushed by using an electric drill, and the double vinyl is packaged at the same time. The sticker on the asbestos-containing material is additionally loaded at the designated loading place and processed according to the waste disposal regulations.

1 is an exemplary view showing a state in which the vinyl is provided on the outlet and the wall to dismantle and remove the ceiling material used asbestos. When dismantling the building materials such as the ceiling material 1, all the exits and the wall surfaces are relieved by using the vinyl sheet 2 and the tape such as blue tape. That is, in the field, the vinyl sheet is cut to a suitable size in consideration of the height and width of the wall surface, and then attached to the wall surface using a blue tape or the like. Thereafter, asbestos dust generated during dismantling of the ceiling material is purified while passing through the filter of the sound pressure device 5 installed in the workplace, and then discharged to the outside.

2 is an external perspective view of a conventional sound pressure device. The conventional sound pressure device 10 is composed of a main body case 11 made of a thin metal plate and a filter and a blower mounted therein. The filter is usually composed of one or two pretreatment filters and a HEPA filter, and a blower is disposed behind the filter. The suction port 12 is formed on one side of the main body, and the discharge port connected to the blower is formed on the opposite side. The main body 11 is typically formed with a carrying handle 13, the moving wheel 14 is mounted on the bottom surface of the main body (11).

Sound pressure gauges vary in size depending on the volume of the treatment, and weigh less than 90 kg to more than 200 kg. In order to use this asbestos demolition site, several workers should work together by hand. However, since the size of the sound pressure machine is often too large and heavy, it is not a laborious task for the worker to transport it to the site. In addition, if there is a staircase in the field, the transport of the sound pressure is more difficult, and when the size of the sound pressure is large, it is difficult to pass through the door of the site. However, there is a problem that if the sound pressure regulator is designed too small, the processing volume or capacity becomes small and inefficient.

In addition, in the conventional sound pressure device, the suction port is mainly formed on the upper surface or one side of the sound pressure device. In this case, there is a problem that asbestos dust scattered in the room, which is the workplace, is not efficiently sucked. Therefore, there is a need to improve the structure that can more safely and efficiently suck asbestos dust scattered in the air or asbestos dust scattered on the floor.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to improve the transport of the large and heavy sound pressure to a separate type to facilitate transport and movement. By doing so, the worker's fatigue is reduced and safety accidents are prevented.

It is still another object of the present invention to improve the structure of the suction port of the negative pressure unit so that asbestos dust flying in the air can be removed reliably and efficiently.

In order to solve the above technical problem, in the present invention, a discharge port is formed through the outer surface and an inlet is formed through the upper body 110 and the lower end side in which the blower connected to the discharge hole is mounted, and the suction port is formed inside the discharge port. It provides a sound pressure, characterized in that the lower body 120 is mounted to be connected to the filter unit is connected to be detachable by the fastening means.

Here, it is preferable that a gasket is mounted on the coupling surface where the upper body and the lower body contact each other.

The suction port is formed on the front, rear, left, and right sides of the lower end of the lower body, it is preferable that the inclined body of the lower light reciprocation is formed inside the suction port.

As the fastening means, a fastening means composed of a set of hooks and latches may be selected.

According to the present invention, there is an advantage in that the sound pressure unit is formed to be separated into a lower body including a filter unit and an upper body including a blower, thereby facilitating transport and movement of the sound pressure device into the workplace. Thus, steep stairs or narrow entrances can pass safely, thereby reducing worker fatigue and preventing safety accidents.

In addition, in the present invention, the suction port is formed on the front surface of the lower end of the sound pressure unit, and an inclined body having an inclined surface is provided at the center thereof to smoothly flow the fluid, thereby increasing the suction efficiency of asbestos dust and the like.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the technical features of the present invention.

3 is a front view of the sound pressure device according to the present invention, FIG. 4 is a right side view of the sound pressure device of FIG. 3, and FIG. 5 is a left side view of the sound pressure device of FIG. 3.

As shown, the sound pressure device 100 of the present invention is largely configured by separating the upper body 110 and the lower body 120. The upper body 110 and the lower body 120 is separated or combined as necessary using the fastening means 123. In the illustrated embodiment, the hook 123a is attached to the lower body 120 and the latch 123b is attached to the upper body 110 to function as the fastening means 123. However, in addition to the upper body 110 and the lower body 120 may be variously selected fastening means for easily coupling or separating. For example, the upper body 110 and the lower body 120 may be coupled or separated by means such as bolts and nuts.

The front of the upper body 110 is provided with a control panel 113 on which the on-off switch or the differential pressure gauge is mounted, one side of the left and right sides is discharged to discharge the purified air after filtering the asbestos dust inhaled ) Is formed. The discharge port 111 is connected to the discharge port of the blower (not shown) built in the upper body (110).

An inlet 121 for sucking asbestos dust and the like is formed on the entire lower surface of the lower body 120, and inclined surfaces 122a, 122b, 122c, and a central portion between the four inlets 121 facing each other. An inclined body 122 having 122d) is formed. The inclined body 122 has a shape of a downlighted upper side, which induces asbestos dust, which flows into the inlet 121, to flow well toward a filter located above the inclined body 122. Play a role. In the conventional general negative pressure machine, only the conventional openings are formed in the suction port, so that the suction efficiency is not satisfactory, and in order to increase the suction effect, one having to select a large blower capacity has to be selected. However, in this case, the size and weight of the entire sound pressure increases, so there is a problem that transportation is not easy, and there was a problem that the safety accident rate is high during transportation. However, when the inclined body 122 is formed in the suction port 121 so that scattering particles such as asbestos dust can flow well, even if only the blower having the same efficiency and capacity can suck the asbestos dust much more efficiently. It will be possible. The reason why the inclined body 122 is formed to have an inclined surface in a down light negotiation manner is that dust or the like is more easily guided toward the filter on the inclined surfaces 122a, 122b, 122c, and 122d along the air flow that the blower inhales. To make it possible. Therefore, unlike the illustrated embodiment, it is possible to form the shape of the inclined body 122 in the shape of a cone, a pyramid, a truncated cone or a pyramid.

Carrying handles 114 and 124 are formed on the side surfaces of the upper body 110 and the lower body 120 so as to separate and transport the sound pressure device 100.

6 is an exploded perspective view of a lower body of the sound pressure device of FIG. 3, and FIG. 7 is a schematic cross-sectional view of the filter unit embedded in the lower body of FIG. 6. Inside the lower body 120, a filter unit 130 as shown in FIG. 7 is mounted. The filter unit 130 is for discharging fresh air by filtering asbestos dust introduced through the inclined body 122, and the primary filter 131, the secondary filter 132, and the tertiary filter 1330. The primary filter 131 is a pre-filter, the secondary filter 132 is called a medium filter, and the tertiary filter 133 is a hepa filter. The pre-filter filters out relatively large particles (5 μm or less in diameter) to extend the life of the expensive HEPA filter, and the intermediate filter is also used to reduce the dust load on the expensive HEPA filter. It is possible to use those classified as 65%, 85%, and 95% of the removal efficiency for the particles, and the HEPA filter has a removal efficiency of 99.97% when passing 0.3 μm Di-Octyl-Phthalate (DOP), which is an artificial dust. The above filter says.

As shown in Figure 6, the sound pressure device 100 of the present invention can be easily separated into the upper body 110 and the lower body 120 by the operation of the fastening means 123, and used in combination with each other again in use There is a characteristic to. Therefore, a gasket 120a made of a material such as rubber is mounted on the coupling surface to which the upper body 110 and the lower body 120 are coupled. The gasket 120a is for preventing air from leaking from the coupling portion between the upper body 110 and the lower body 120, and any one coupling surface selected from the upper body 110 and the lower body 120. Alternatively, it may be formed on both side engaging surfaces.

As the blower mounted in the upper body 110, a centrifugal blower or an axial blower may be used, but it is preferable to use a centrifugal blower having a relatively high pressure structure.

Although not shown, it is preferable to connect a differential pressure gauge to the filter unit 130. The differential pressure gauge may be connected to each of the primary, secondary and tertiary filters or may be connected to the entire filter unit 130. If the filter differential pressure is too low, there is a gap somewhere, indicating that the sucked dust is leaking. If the filter differential pressure is too high, the filter is clogged and the amount of air sucked is very small. In this case, the filter should be replaced.
