Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bypass light pipe having a pressurizing unit and a mining system including the same,

The present invention relates to a bypass pipeline for mining deep-sea mineral resources and a mining system including the same, and more particularly, to a mining system including a bypass pipeline for mining deep- The present invention relates to a bypass light pipe having a pressurizing portion capable of preventing the falling slurry from being backwardly conveyed back to the positive pump.

Due to the increasing demand for mineral resources and the unstable international situation, securing of mineral resources has become a very important issue in the national strategy and policy level.

In order to cope with the supply and demand uncertainty of future mineral resources, it is urgent to secure long-term stable supply sources of strategic metals resources in Korea. The manganese nodules at about 5,000m below sea level contain a large amount of useful metals such as manganese, nickel, cobalt and copper and are evaluated as a new alternative for future mineral resources.

A pumping system that lifts manganese nodules at depths of about 5,000 m is composed of a pumping system, a buffer system and an oil-related system, which are classified as a hydraulic pumping system and an air-pumping system.

However, if the flow of the nodules is interrupted for unexpected reasons, the slurry of the nodules accumulates in the light pipe, which may make it impossible to restart the system. To prevent this, a device for desludging the nodules is desperately needed .

On the other hand, the conduit is installed to move the fluid in one direction, and various valves are installed to control the supply of the fluid.

These valves are equipped with check valves, which are installed in the pipeline to prevent backflow of the fluid flowing in the pipeline and to flow only in one direction. The check valves are opened by the fluid pressure, When the valve stops or flows backward, the valve automatically closes due to gravity or a spring that presses the valve plate.

Such check valves are used in general piping, sewerage, waterworks, factory-used pressure piping or automobile engines to prevent damage to the gears and threads of the drive motors.

Here, a water hammer is a water hammer that can cause water hammer. When a fluid flows inside a pipe, sudden pump operation is stopped due to power failure or malfunction. Accordingly, the kinetic energy of the fluid is converted into pressure energy as the pressure in the tube rises or falls rapidly due to a sudden change in the flow rate of the fluid flowing through the tube, and a high pressure is generated immediately before the valve. .

Such a water hammer causes the valve plate to abruptly repeatedly bump into the valve seat, resulting in abrasion or damage such as damage to pipes, valves, and peripheral devices, thereby shortening the service life.

Therefore, the check valve must be designed so that it does not affect the pressure drop or the state of the flow in order to prevent backflow while preventing such a water hammer, it must be easy to open and completely pass the fluid, Should not.

In addition, the water tightness must be large enough to prevent reverse flow, and there should be no damage to parts in all emergency situations during operation.

Conventional check valves to meet these requirements include swing check valves, dual plate check valves, axial flow check valves, and the like.

The swing check valve is the most commonly used type of check valve. It has the advantages of easy opening, closing, opening and closing of the disk by the arm and rod pin, no restriction of pressure and size, and relatively low pressure loss.

However, there is a problem that breakage of split pins, disc nuts, connecting parts, and the like may occur, and there is a limit not suitable for vertical piping.

The dual plate check valve has a low noise level at any position, has a relatively low pressure loss, and has no limitation in installation direction.

 However, there is a problem that pipes, valves, and peripheral devices may be easily damaged such as abrasion or damage due to sudden repetitive collision of the plate with the valve seat.

Axial flow check valve has advantages of short operating distance of disk, simple structure, small shock, vibration and noise due to valve operation, and stable control of flow.

However, when the pressure in the tube rises suddenly due to a sudden change in the flow rate of the fluid that has flowed through the tube due to electrostatic breakdown or failure due to the top shape of the disk, the fluid abruptly and repeatedly bumps into the disk, There is a limit that can not be avoided.

Therefore, even when the abnormal fluid such as the clogging of the pipeline or the operation stop of the pump is generated and the fluid that has been transferred abruptly descends in the reverse direction, not only the falling fluid is prevented from flowing back to the pump again, A high watertightness is ensured, and a means is required to minimize wear and damage even if the fluid suddenly and repeatedly bumps into the valve.

One end of the housing 160 is connected to the support shaft fixing part 150 and the second light pipe through the second connection part 162 and the other end is connected to the first light pipe through the first connection part 161 , 4c and 6), and a discharge portion 120 for discharging the slurry in the reverse direction to at least a part thereof. Here, the discharge unit 120 is preferably formed on both sides of the housing 160.

The discharge unit 120 includes a discharge port 121 formed on both sides of the housing 160 and having a predetermined diameter and a bypass pipe 122 branched and extended downward from the discharge port 121 at a predetermined angle. The bypass pipe 122 functions as a passage for discharging the slurry in the reverse direction.

The branching angle of the bypass pipe 122 is preferably in the range of 10 to 45 degrees in order to reduce the friction with the slurry in the bypass pipe 121 at the time of transferring the slurry.

If the branching angle is excessively small, the diameter of the bypass pipe 122 must be increased. If the branch pipe diameter is excessively large, large damage due to friction occurs in the bypass pipe 122 at the branching point during slurry transfer, 2 durability of the light pipe is deteriorated.

The flow tube 110 includes a first opening portion 111 and a second opening portion 112. The first opening portion is connected to the first positive light pipe and the second opening portion 112 is connected to the second positive light pipe . Accordingly, when the forward slurry is transferred, the slurry flows into the housing 160 through the first opening 111 through the first light pipe by the pressure of the pump C,

The valve block 130 located in the flow tube 110 inside the housing 160 slides vertically along the inner wall of the flow tube 110 and opens and closes the outlet 121 of the flow tube 110 to feed the slurry in the forward direction Or the slurry in the reverse direction is transferred to the bypass pipe 122.

The valve block 130 includes a block body 132 for opening and closing the discharge port 121 and moving up and down, a receiving groove 133 for a space formed inside the block body 132, And a transfer tube 134 formed on both sides of the block body 132. [

The block body 132 preferably forms a central portion of the valve block 130. The transfer tube 134 is preferably formed to communicate with the flow tube 110 so that the forward slurry can be transferred.

The pressing portion 131 is formed at a lower portion of the block body 132 and is preferably formed to have a tapered cross section having a maximum width larger than the maximum diameter of the first opening portion 111. [

At this time, the flow rate passing through the valve block 130 may vary depending on the sizes of the transfer tube 134 and the pressing part 131. The size of the transfer tube 134 and the size of the pressing part 131 can be independently determined with respect to each other so that the size of the transfer tube 134 and the size of the pressing part 131 can be adjusted, It is possible to easily design and produce the display device 100.

The diaphragm 100 having the same size as the housing 160 has the same structure as that of the second diaphragm and the first diaphragm connected to the upper and lower portions, The flow rate can be determined according to the size of the pressurizing portion 131.

Particularly, since the pressing portion 131 protrudes downward from the valve body 132, even if the size of the transfer tube 134 is increased, the pressure from the pump C is not affected by the size of the transfer tube 134 I can receive it as it is. Furthermore, the larger the pressing portion 131, the wider the area where the pressing portion 131 is subjected to pressure weighting.

Even when the slurry is conveyed in the reverse direction, even when the size of the transfer pipe 134 is increased, the pressing portion 131 has a tapered cross-section having a maximum width larger than the maximum diameter of the first opening 111, 111) can be easily closed.

The maximum width of the tapered end face of the pressing portion 131 is preferably the width of the lower portion of the valve block 130 including the portion where the pressing portion 131 is protruded to both sides of the valve body 132, It is preferable that the width gradually decreases from the maximum width toward the center of the lower portion of the pressing portion 131. [ It is also preferable that the lower side of the tapered section, that is, the lower side of the pressing portion 131 has a curved shape.

The slurry is easily guided from the first opening 111 to the transfer pipe 134 of the valve block 130 at the time of transfer of the normal slurry by having the pressurizing portion 131 having a tapered cross- .

The supporting portion 140 preferably includes a supporting shaft 141, a pusher portion 142 and a damper spring 143. The supporting shaft fixing portion 150 preferably includes a feeding groove 151 and a fixing member 152 Do.

The support portion 140 is configured to allow the valve block 130 to stably move up and down. The support shaft 141 is preferably connected to one end of the support shaft 150 and the other end of the support shaft 141 is received in the receiving groove 133 of the valve block 130.

The pusher portion 142 is protrudingly formed on at least a part of the support shaft 141 and is disposed in contact with one end of the damper spring 143 located in the receiving groove 133. The damper spring 143 is disposed between the pusher portion 142 and the lower side surface of the receiving groove 133 so that when the pressure portion 131 receives pressure of the positive pump C, So that the distance d between the pusher portion 142 and the receiving groove 133 is narrowed and contracted.

The damper spring 143 is loosened again when the slurry is conveyed in the reverse direction and the valve block 130 is immediately lowered to widen the distance d between the pusher portion 142 and the receiving groove 133. [

It is preferable that the support and retention part 150 is fixed by the fixing member 152 on the second connection part 162 of the housing 160 (see FIG. 4C). Accordingly, the second light pipe can be stably connected and fixed to the fixing member 152, but the second light pipe and the bypass light pipe according to the present invention are not limited to such a connection method.

It is preferable that the feed groove 151 is a groove configured so that the slurry in the forward direction or the reverse direction can pass through the support shaft fixing portion 150. The transfer groove 151 is preferably formed at a position corresponding to the second opening 112 so that the slurry passing through the second opening 112 can easily pass through the second diaphragm.

The operation of the bypass diaphragm having the pressurizing unit according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7 as follows.

Referring to the drawings, the light pipe includes a bypass pipe (not shown) having one side connected to the lower portion of the watercourse E, the other side connected to the positive pump C, And a flow pipe 110 in which a fluid pipe 120 is formed.

And a housing 160 surrounding the outer circumference of the flow pipe 110. The valve block 130 includes a valve block 130 that slides up and down along the inner wall of the flow tube 110 to open and close the outlet 121 at the branch point.

Normally, when the slurry is conveyed upward by the pressure of the pump C, the valve block 130 moves upward along the inner wall of the flow pipe 110 to close the discharge port 121, so that the slurry is normally transported.

At this time, the pressure body 131 is primarily subjected to the pressure of the light pump C, so that the block body 132 can move upward upward along the inner wall of the flow tube 110 more easily. The damper spring 143 is secondarily contracted due to the pressure from the downward direction to function as a shock absorber to prevent the valve block 130 from being damaged.

The damper spring 143 is accommodated in the valve block 130, so that the damping spring 143 is more stably shrunk and relaxed, and the durability is improved.

The slurry flowing through the first opening 111 and flowing into the housing 160 through the valve block 130 passes through the transfer pipe 134 and passes through the second opening 112, And is conveyed to the water-line E through the light pipe.

However, when an abnormal condition such as clogging of the first or second light pipe or interruption of the operation of the pump C is caused, the slurry to be conveyed abruptly drops downward.

At this time, the valve block 130 is immediately moved downward along the inner wall of the flow pipe 110 by the dropping hydraulic pressure and the action of the damper spring 143 so that the falling slurry is not transferred to the positive pump C, 131 closes the passage to the first light pipe.

That is, when the pressurizing portion 131 closes the first opening 111, the passage to the first light pipe, which is a pipe toward the forward pump C, is closed and the reverse slurry falls to the forward pump C Is effectively prevented.

Instead, the bypass pipe 122 at the branch point is opened, so that the slurry is conveyed through the bypass pipe 122, not the first diaphragm pipe directed to the positive pump C, and is discharged to the outside.

At this time, the damper spring 143 is loosened again by the elastic force and functions to push down the valve block 130 while the lower side of the pusher portion 142 and the receiving groove 133 is opened.

The bypass throttle tube of the present invention is operated by the pressure of the positive pump (C) in the forward direction, that is, the upward direction, and the pressure generated by the fluid flow of the falling slurry in the reverse direction, It is manufactured in a passive form to be operated.

As described above, even when the unfavorable situation such as clogging of the light pipe or interruption of the operation of the pump is caused and the slurry to be conveyed is rapidly dropped downward, And is conveyed through a bypass pipe instead of a conduit leading to the positive pump so as not to be conveyed back to the pump again.

In this way, even when the fluid that has been conveyed abruptly descends in the opposite direction due to occurrence of an abnormal situation such as occurrence of clogging of the pipeline or interruption of operation of the pump, the falling fluid is prevented from flowing back to the pump again so as to prevent damage to the pump .

In addition, a pressurizing portion can be provided to immediately close the pipeline to the light pump in an airtight manner, so that the falling slurry can be prevented from flowing back to the light pump.

Also, the size of the transfer tube and the size of the pressing portion can be determined independently of each other, so that the bypass tube can be easily designed and manufactured by adjusting the size of the transfer tube and the size of the pressing portion.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications may be made without departing from the spirit and scope of the invention.
