Description

Water sealing type movable duct of dust collector

The present invention relates to a mobile dust collecting duct which is configured to collect dusts discharged from a working machine while moving together along a working machine moving a certain area, and is capable of maintaining a tight air tightness using a fluid. .

In general, a dust collector including a suction duct for collecting dust emitted from the work machine and a dust collector main body connected to the outlet of the suction duct to filter dusts transferred through the suction duct is essential. It is provided.

Among them, a dust collector other than the above is required to collect dust emitted from a mobile work machine that performs work while moving a certain section.

As shown in FIG. 1, the conventional mobile dust collector includes a dust collector main body 1 and a bellows suction duct 2 connected to the dust collector main body 1 so that the bellows suction duct 2 is a mobile work machine (A). It is designed to collect dust emitted from the mobile work machine (A) while moving along a certain section along).

However, since the dust collector main body 1 is fixed at a predetermined position in the mobile dust collector, the length of the suction duct 2 must also be extended together with the moving section of the working machine. Therefore, as the moving section of the working machine becomes longer, the length and weight of the suction duct 2 become excessive, and thus the durability of the suction duct 2 is greatly weakened, and the suction duct 2 sags downwards. Interference with the same peripherals increases the risk of causing an accident during operation.

Recently, a sealed mobile dust collection duct has been developed to solve this problem.

"It is discharged through the male duct 20 to the water sealing portion 32 of the water sealing duct 30, in this process heavy dust is collected in contact with the fluid contained in the immersion portion 31, light dust that does not contact the fluid They are sucked into the dust collector main body 40 and processed.

Therefore, when the dust collecting device is configured using the water-sealed mobile dust collection duct, it is possible to manufacture a simple structure by using the same small suction duct regardless of the moving section of the working machine (A). Therefore, the problems caused by the length of the suction duct can be solved at once.

However, the conventional water-sealed mobile dust collecting duct has the following problems.

First, dust collected by the fluid contained in the immersion part 31 does not go to the bottom of the submerged duct 30, so it needs to be periodically cleaned, and the bottom of the submerged duct 30 is narrow and closed, so the cleaning is performed. Very difficult to do

"자형 덕트(20)가 이동흡입덕트(10)를 따라 이동할 때 유체와의 저항이 발생하게 된다. 따라서, 이동흡입덕트(10)가 이동할 때 침지부(31)에 담겨진 유체가 출렁거리게 되고 심할 경우 유체가 외부로 넘쳐 흘러 주변을 오염시키는 문제가 있다.second, "

"When the female duct 20 moves along the moving suction duct 10, resistance with the fluid is generated. Therefore, when the moving suction duct 10 moves, the fluid contained in the immersion part 31 is slack and severe. In this case, there is a problem that the fluid overflows to the outside and pollutes the surroundings.

Third, since the immersion part 31 has a structure in which the upper part is opened, rainwater is easily introduced into the dust collecting device mainly installed outdoors or the fluid contained in the immersion part 31 is easily evaporated.

"자형 덕트(20)의 단부(21)가 수면 아래로 잠기면서 집진장치가 정상적으로 동작되지 않게 되고, 침지부(31)에 담겨진 유체가 외부로 넘쳐 흘러 주변을 오염시키게 된다.If rainwater is continuously introduced and the level of the fluid contained in the immersion unit 31 becomes too high, "

"The end 21 of the female duct 20 is locked below the surface of the water, the dust collector is not normally operated, the fluid contained in the immersion unit 31 overflows to the outside to pollute the surroundings.

"자형 덕트(20)를 빠져나온 분진들이 유체에 채집되기 힘들게 되므로 정상적인 집진기능을 발휘할 수 없게 된다.If the fluid is evaporated and the level of the immersion part 31 becomes too low,

"The dust coming out of the duct 20 is difficult to be collected in the fluid is not able to exhibit the normal dust collection function.

Therefore, the worker periodically pays attention to whether the fluid contained in the immersion unit 31 is within a range of a certain level, and it is very troublesome to adjust the changed level one by one.

"자형 덕트(20)는 단위길이당 유체의 사용량이 많고 이에 따라 고중량이다. 따라서, 유체의 사용량이 많고 덕트 자체의 강도보강도 요구되므로 별도의 지지부재나 설치바닥면에 대한 보강공사가 추가로 실시해야 할 필요가 있다.fourth, "

"The duct 20 has a large amount of fluid per unit length and thus a heavy weight. Therefore, since the amount of the fluid is used and the strength of the duct itself is also required, additional reinforcing work for a separate supporting member or installation floor is additionally performed. It needs to be done.

The present invention has been made to solve the above problems, it is easy to clean the sealing duct, while the resistance of the fluid and the moving duct contained in the immersion is minimized, the level of the fluid contained in the immersion is always constant It is an object of the present invention to provide a sealed mobile dust collection duct which is maintained and the amount of fluid used is reduced.

In order to achieve the above object, the present invention comprises a mobile suction duct for collecting dust emitted from the mobile work machine while moving a certain section along the mobile work machine; A “U” shaped duct formed at the bottom of the movable suction duct; It is installed along the movement path of the moving suction duct and the immersion part in which the fluid is contained so that the end of the "U" -shaped duct is exposed on the water surface, and the end of the "U" -shaped duct exposed on the water surface to the outside. A water sealing duct provided to block the water sealing duct connected to the dust collector main body; Outlets respectively formed at both ends of the bottom of the immersion unit to discharge dust accumulated on the bottom of the immersion unit; And installed on the lower end of the "U" -shaped duct, it characterized in that it comprises a dust transport means for moving the dust accumulated on the bottom of the immersion portion to the discharge port side when the "U" -shaped duct moves.

The present invention configured as described above has the following effects.

"자형 덕트에 비해 내부체적이 작으므로 내부에 담겨지는 유체의 양도 작아 단위길이당 유체의 사용량이 작고 이에 따라 저중량이다. 따라서, 종래와는 달리 덕트 자체의 강도보강도 요구되지 않고 별도의 지지부재나 설치바닥면에 대한 보강공사가 추가로 요구되지 않으므로 제작성이 용이하고 제작비를 절감할 수 있는 효과가 있다.First, the "U" duct of the present invention is a conventional "

"The internal volume is smaller than that of the duct, so the amount of fluid contained in it is small, so the amount of fluid used per unit length is small and therefore low weight. B There is no need for additional reinforcement work on the installation floor, so it is easy to manufacture and can reduce the production cost.

Second, the present invention is formed in the outlet for the discharge of dust in the bottom of the immersion and the brush attached to the "U" -shaped duct can easily clean the dust settled on the bottom of the immersion in the process of moving the "U" -shaped duct It has an effect.

Third, the present invention is formed by narrowing the end facing the moving direction of the "U" -shaped duct to minimize the resistance of the fluid contained in the immersion part, the fluid contained in the immersion part flows to the outside when the "U" -shaped duct moves Since the fall is prevented, the work area is cleaned.

Fourth, the present invention is a drain hole is formed on the upper end of the immersion part when the fluid of the immersion part is more than a certain level automatically discharges the fluid contained in the immersion part, the fluid supply means is provided in the lower part of the immersion part When the fluid is below a certain level, the fluid is automatically supplied into the immersion part. Therefore, since the level of the fluid contained in the immersion is automatically adjusted, there is an easy management effect.

The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings, and for clarity, only different parts will be mainly described so as not to overlap with similar parts as in the prior art.

As shown in Figure 4, the water-sealed mobile dust collection duct of the present invention is a mobile suction duct 110 to collect the dust discharged from the mobile working machine (A) while moving a certain section along the mobile working machine (A), An “U” shaped duct 120 formed at the lower end of the movable suction duct 110 and an end portion of the “U” shaped duct 120 are installed along the movement path of the movable suction duct 110. The dust collector body 132 is provided with an immersion portion 131 in which fluid is exposed so that 121 is exposed on the water surface, and a water sealing portion 132 for blocking the end 121 of the “U” -shaped duct 120 exposed on the water surface from the outside. A water sealing duct 130 connected to the 140 is basically provided.

The fluid contained in the immersion part 131 is suitable for water, and there is a risk of freezing in the winter, so the antifreeze may be mixed.

According to the present invention, discharge openings 133 for discharging dust accumulated on the bottom of the immersion unit 131 are formed at both ends of the bottom of the immersion unit 131, respectively. Discharge pipes 134 are connected to the discharge ports, respectively.

And at the lower end of the "U" -shaped duct 120 is installed dust transport means. The dust transfer means pushes dust accumulated on the bottom of the immersion part 131 when the "U" -shaped duct 120 is moved to move toward the outlet 133. A door (not shown) is installed at the lower end of the discharge port 133, and the door is normally closed, and when dust is accumulated to some extent, the door is opened to discharge only the dust and close again.

As the dust transfer means, any material or shape can be used as long as the dust can be pushed and moved, such as a cloth or a panel, but the brush 122 is preferable. This is because the brush 122 can maintain the initial shape as it is while being immersed in the fluid and there is almost no resistance with the fluid during the movement, so that the brush 122 can move smoothly as if sweeping toward the outlet 133 without losing dust. The material of the brush 122 is a suitable synthetic resin.

As shown in FIG. 5, the “U” -shaped duct 120 preferably has narrow ends 121a and 121b facing the moving direction. This is to minimize friction with the fluid when the "U" -shaped duct 120 is moved. As such, when the end portions 121a and 121b facing the moving direction of the “U” -shaped duct 120 are formed to be narrow, the brush 122 is accumulated on the bottom of the immersion part 131 while the flow of fluid is minimized. It is possible to move to the outlet 133 side without losing them, and because the surface is not shaken, the fluid contained in the immersion unit 131 flows to the outside to prevent the phenomenon of polluting the surroundings. Here, the shapes of the end portions 121a and 121b facing the moving direction of the “U” -shaped duct 120 also include a streamlined shape.

As shown in FIG. 6, when the fluid in the immersion part 131 exceeds a predetermined level so that the fluid contained in the immersion part 131 does not flow out of the water sealing duct 130 at an upper end of the immersion part 131. A drain hole 135 for automatically discharging the fluid contained in the immersion unit 131 may be further formed. The drain hole 135 is connected to the drain pipe 136 for moving the fluid discharged to the outside through the drain hole 135 to one side.

Therefore, when the water-sealed mobile dust collecting duct of the present invention is installed outdoors, even if rainwater flows into the immersion part 131 and the level of the immersion part 131 increases, the water level in the immersion part 131 through the drain hole 135 is increased. Since the constant is adjusted so that the fluid flows into the end 121 of the "U" -shaped duct 120 or the fluid flows out of the immersion portion 131 and does not pollute the surroundings.

In addition, the immersion unit 131 may be provided with a fluid supply means 150 for automatically supplying the fluid into the immersion unit 1 when the fluid is below a certain level.

The fluid supply means 150 is rotatably coupled to the water supply pipe 151 installed in the immersion part 131, the on / off valve 152 provided on the upper side of the water supply pipe 151, and the on / off valve 152. The rod 153 is connected to open and close the on-off valve 152 according to the rotational state, and is connected to an end of the rod 153 to operate the rod 153 up and down according to a change in the water level in the immersion part 131. It consists of a mouthpiece 154 for starting or interrupting the supply of water into the branch 131.

Therefore, when the water level of the immersion portion 131 is lower than the normal water level, the float 154 is lowered, and the opening / closing valve 152 connected to the rod 153 is opened along the descending float 154. The fluid is discharged from the water supply pipe 151 through the opening / closing valve 152, thereby raising the level of the immersion part 131. When the water level of the immersion portion 131 reaches the normal level, the float 154 becomes horizontal and at the same time the open / close valve 152 is closed. Therefore, since no more fluid is supplied into the immersion part 131 through the water supply pipe 151, the normal water level is maintained. Of course, the normal water level should be set to a height lower than the end 121 of the "U" -shaped duct (120).

On the other hand, considering that the "U" -shaped duct 120 moves inside the immersion part 131, the fluid supply means 150 of the immersion part 131 so as not to interfere with the "U" -shaped duct 120 It is preferably installed at the front end or the rear end. In the present embodiment, for example, but is installed on the rear end of the immersion portion 131 is not necessarily limited thereto.

As described above, preferred embodiments of the present invention are described above with reference to the drawings, but the present invention is not limited to the above-described embodiments, and those skilled in the art may modify the present invention without departing from the spirit of the present invention. Possible, such modifications will fall within the scope of the invention.
