Description

Exhaust line piping cleaning system {Exhaust line Piping Cleaning System}

The present invention relates to a pipe cleaning system, and more particularly, to an exhaust line pipe cleaning system at the rear end of a vacuum pump or a scrubber.

Scrubbers play a role in purifying harmful substances discharged from various types of industrial facilities. The scrubber accepts harmful substances through inlets connected to various void chambers, processes them wet or dry, and discharges purified air through outlets. Several scrubbers are deployed at industrial sites, and each scrubber outlet includes a pipe. Each scrubber outlet pipe is connected to the main duct, and in most cases has a complicated path leading to the main duct. That is, the pipe extending upward from the top of the scrubber has several curved portions to implement a complex path. Such a scrubber pipe may contain some untreated dust in addition to gas, which accumulates in the pipe over a long period of time, resulting in clogging of the pipe or performance deterioration in which discharge is not discharged through the pipe in an originally calculated state. It is necessary to solve the problem of pipe clogging or performance deterioration of the pipe in the discharge section while the life of the scrubber is sufficiently remaining.

As a related prior art document, Patent Publication No. 10-2003-0081592 installs a filter and a dust collector to manage pipes. However, since these facilities do not actively clean the pipes, problems may arise in management during long-term use.

Accordingly, an object of the present invention is to provide a cleaning system capable of cleaning a scrubber pipe without disassembly and disassembly.

According to the present invention, there is provided a pipe cleaning system having a nozzle head that can be injected into the pipe and can pass through the curved part freely while implementing a bending operation.

The nozzle head portion is composed of a rear spray nozzle that sprays water in a direction opposite to the direction of travel in the pipe, and surrounds and supports the end of the rear spray nozzle so that the rear spray nozzle can proceed without causing friction in the pipe. A plurality of wings It is provided with a screw-type support having a.

In addition, the nozzle head part has a predetermined section of an elastic body, a bellows, or a spring-type elastic part extending from the rear injection nozzle and the screw-type support so as to be able to pass while being bent along the curved portion of the pipe.

In addition, an endoscope camera is installed at the foremost part of the nozzle head unit to photograph the inside of the pipe and transmit the image to the display unit of the pipe cleaning system.

In addition, the cable connected to the nozzle head unit includes a high-pressure hose for supplying water to the rear nozzle, a transmission line for an endoscope camera, and a loader with tension so that the cables can be propeled with appropriate tension. The entire outer skin of the bundle is taped with low-friction film. The high-pressure hose is connected to a pump, and a lubricant is applied to the outside of the taped cable.

The cable is wound around a roller, and is unwound and supplied from the roller as the nozzle head proceeds. A distance meter is installed on the roller to measure the moving distance of the nozzle head in real time and transmit it to the display unit of the pipe cleaning system.

As the cable proceeds inside the pipe together with the nozzle head, the high-pressure water sprayed backward from the rear nozzle carries dust, powder, and foreign substances accumulated inside the pipe into the high-pressure water so that the high-pressure water flows in the opposite direction to the direction the cable travels inside the pipe. and flows into the tank-type collection part connected to the end of the pipe (entry part of the cable and nozzle head), and the collection part is emptied as needed.

In addition, a glove box is installed to assist the supply of the cable in the pipe so that the operator manually supplies propulsive force to the cable while wearing a glove.

A motor and a motor control button may be installed so that the cable is automatically unwound from the cable roller and supplied into the pipe.

According to the present invention, a scrubber pipe cleaning system capable of cleaning the inside of a pipe with high pressure water without disassembly and disassembly of the pipe having a complicated path over the top of the scrubber is provided. In addition, a pipe cleaning system that can be applied to cleaning of an exhaust line at a rear end of a vacuum pump is provided.

The scrubber pipe is located in a high place and has a plurality of elbows bent at an angle of 90 degrees, so there is a difficulty in that general nozzles cannot proceed along such a path. It allowed free passage through the true elbow section.

In addition, the nozzle provided in the nozzle head of the present invention is a rear nozzle that sprays high-pressure water in a direction opposite to the direction the nozzle travels. Thanks to the high-pressure water, the nozzle gains a thrust in the direction of travel.

In addition, the present invention surrounds the rear nozzle and configures a screw-shaped pedestal so that the portion in contact with the pipe wall is small, so that the nozzle moves along the pipe wall to reduce the frictional force and reduce the force required for progress.

In addition, the endoscope camera provided at the front end of the nozzle head of the present invention captures the state of the inner wall of the pipe as an image and transmits the image to the display unit, so that the operator can control the moving speed of the nozzle while checking the state of the inside of the pipe in real time.

In addition, in the present invention, a loader having tension is added to the cable connected to the nozzle head in addition to the high-pressure hose and the endoscope camera transmission line, so that the three cable bundles have appropriate tension as a whole to facilitate the nozzle head to move smoothly.

In addition, while the cable is automatically or manually unwound from the roller, the travel distance of the nozzle head can be known through a distance measuring device that measures the unwinding length. can figure it out

In addition, the scrubber pipe cleaning system of the present invention is configured in the form of a movable cabinet, so that it can be easily moved to the place where the scrubber needs pipe cleaning to perform cleaning work, and the collection box for collecting contaminants as long as the cleaning is performed is also movable and convenient. can be moved

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the overall configuration of the scrubber pipe cleaning system of the present invention.

1 shows that the scrubber pipe 20 extending upward from the top of the scrubber 10 is connected to the main duct 30 through a complicated path. The pipe 20 reaches the main duct through several bent elbows, and although only one scrubber pipe is shown in FIG. 1, pipes from multiple scrubbers may be connected to the main duct. The scrubber pipe cleaning system 100 of the present invention for cleaning the inside of the scrubber pipe 20 is configured as a movable type that can move close to the scrubber. The scrubber pipe cleaning system 100 has a docking pipe so that the nozzle for cleaning the inside of the scrubber pipe 20 can enter the pipe, and as the pipe 20 is cleaned, washing water and foreign substances are collected together. The tank type collection unit 150 is also movably installed.

In the case of pipe cleaning work, it is not difficult to clean the pipe that extends downward, such as sewage, but it is not difficult to advance the cleaning nozzle, but since the scrubber pipe extends upward and has many elbows bent at 90 degrees, existing pipe cleaning equipment cannot be cleaned with

Therefore, it is necessary to have the flexibility to pass while bending along the curved elbow part and the elasticity to go straight again after passing through the elbow, and the propulsive force must be reduced by reducing the friction with the inner wall of the pipe.

In addition, the washing water must be high-pressure water that can wash foreign substances such as dust and powder inside the pipe 20, and is cleaned by the high-pressure water so that contaminated water containing foreign substances does not flow into the main duct of the scrubber and the pipe 20 ) and flow backward to the collection unit 150.

Accordingly, the present invention applies the rear spray nozzle 210 as shown in FIG. Since the rear injection nozzle is commercially available, a description of its structure is omitted. The rear injection nozzle 210 injects water in the opposite direction to the direction of the nozzle, that is, to the back of the nozzle head, and a plurality of water injection holes are formed along the circumference of the nozzle shaped like a crown to form a high pressure in a 360-degree direction like a fountain. number is sprayed. On the right side of FIG. 2 , a scene in which water is strongly sprayed backward by the rear spray nozzle is shown as a photograph.

Since the rear spray nozzle 210 moves forward while spraying the high-pressure water backward inside the scrubber pipe 20, the contaminated water flows to the back of the pipe while washing foreign substances accumulated on the pipe wall. The high-pressure water sprayed backward provides a driving force to the relatively rear spray nozzle 210 to help the nozzle advance.

On the other hand, when cleaning the inside of the pipe by the rear spray nozzle 210, an endoscope camera 230 that can see the inside of the pipe is installed at the front of the nozzle so that the inside of the pipe can be cleaned a little longer or proceed faster depending on the state of the inside of the pipe do. 3 shows the configuration of the nozzle head 200 including the endoscope camera 230 as a whole.

An endoscope camera 230 is installed at the forefront of the nozzle head 200 to photograph the inside of the pipe and transmits the image to the display unit provided in the scrubber pipe cleaning system 100. The endoscope camera is connected to the transmission line and electrically connected to the display unit. The display unit is provided with an image processing module, and displays images in real time on a display installed on the outer wall of the cabinet-type scrubber pipe cleaning system 100 so that the operator can adjust the nozzle progress while grasping the pipe interior situation.

In addition, in order to reduce the frictional force experienced between the rear spray nozzle 230 and the inner wall of the pipe, a nozzle support 220 having a structure capable of reducing an area in contact with the pipe wall is assembled to the nozzle end. In this embodiment, a screw-type support 220 is applied, which protrudes a plurality of wings at predetermined intervals, like a support supporting a rocket body, so that the nozzle body does not directly contact the inner wall of the pipe, but the blades of the wings touch. This reduces the contact area with the pipe. When the rear spray nozzle rotates, the screw-type support can also rotate with it, and only a few blades always touch the bottom of the pipe. A support having an appropriately deformed structure may be applied in a form other than the screw type as long as it can reduce friction and help the movement of the nozzle.

In addition, as described above, the pipe 20 has a plurality of elbows and bends several times to reach the main duct. The elastic part 240 is provided with a predetermined length. The elastic part 240 has a length sufficient to cover the start and end points of the elbow, and may be approximately 15 to 25 cm long. Although the elastic part 240 may be composed of an elastic material such as rubber. Preferably, it is composed of springs or bellows. The embodiment of the present invention applied a metal spring.

On the other hand, the high-pressure hose for supplying water to the rear spray nozzle 210 is connected to the rear spray nozzle, and the end thereof is connected to the high-pressure water supply unit. In this embodiment, the water bottle 160 and the pump 300 for supplying water at high pressure ) is connected to (see FIG. 5). The high-pressure hose has a sufficient length and is connected to the latter spray nozzle, and is located in the elastic part 240 at the nozzle head part.

The rear spray nozzle 210 is connected to a high-pressure hose and a transmission line of an endoscope camera, and since the tension of the cable is not sufficient with only these two cables, it is insufficient to obtain propulsive force inside the pipe. Therefore, the present invention adds a separate loader capable of strengthening the tension together with the high-pressure hose and the transmission line of the endoscope camera.

4 shows a detailed configuration of the cable 250.

The high-pressure hose 270 that supplies high-pressure water to the rear spray nozzle 210, the endoscope camera transmission line 280, and the loader 290 that strengthens the tension to receive the propulsive force well are bundled and supplied as one cable 250 do. Substantially, the entire cable 250 composed of a bundle of three cables enters the elastic portion 240 at the nozzle head portion 200, and the bundled cable is taped with a tape having a small friction coefficient, and the tape may be in the form of a hose. there is. In addition, to further reduce friction, a lubricant is applied to the outside of the tape and supplied into the pipe.

5 is a schematic diagram showing the overall configuration of the scrubber pipe cleaning system 100 of the present invention. Since it is a schematic diagram, it should be considered that some of the actual situations have been omitted and simplified.

The cable 250 is wound around the roller 600 and then unwound to enter the inside of the pipe. As described above, the cable 250 is composed of a high-pressure hose, a transmission line, and a loader, and the high-pressure hose has an end connected to the pump 300 connected to the water bottle 160, and is not shown in FIG. Through the rollers of the cable roller 600 is incorporated, and the transmission line is also incorporated into the cable roller 600 in the same way. That is, in the process of going to the roller 600 through a separate roller before entering the roller 600, a part of the end side of the high pressure hose and the transmission line becomes bundled with the loader, and the cable 250 in the bundled state is connected to the roller 600 to prepare for entering the pipe, and the nozzle head is mounted on the end of the bundled cable to enter the pipe.

The cable 250 unwound from the roller 600 passes through the glove box 400 and enters the connection pipe 120 connected to the end of the scrubber pipe. The glove box 400 may add a driving force so that a worker puts his/her hand into the glove box, grabs the cable 520, and proceeds in a moving direction. However, as the cable is automatically unwound from the roller 600 by the motor without manual assistance, the rear spray nozzle can be moved by the propulsive force of the cable.

A distance measuring sensor (not shown) for measuring the unwinding length of the cable 250 may be installed on the roller 600 to count the progress of the rear spray nozzle, and the unwinding length may be numerically displayed on the display unit.

There is a pressure sensor (not shown) in the glove box 400 to prevent excessive pressure from being applied to the glove box 400 due to a reverse flow of gas from the side of the pipe 20. The pressure value is displayed on the display and the pressure sensor measured value A switch is installed to stop all operations of the rear spray nozzle and the cable 250 supply roller 600 when a predetermined pressure is reached.

The scrubber pipe cleaning system 100 in the form of a cabinet includes a collection unit 150 movably outside the cabinet to collect cleaning water (contaminated water) after cleaning the pipe 20. This is because the collection unit 150 in the form of a water tank can be emptied frequently, so it is located outside the cabinet. However, you can also place the geography inside the cabinet. When the collecting unit 150 needs to be emptied, it can be easily moved to a designated place because it is movable with wheels.

There is a display unit 500 on one side of the cabinet, and a touch screen and an endoscope camera monitor are installed, so that various data such as the travel distance of the cable and the pressure in the glove box and the inside image of the pipe transmitted by the endoscope camera are displayed while viewing the rear spray nozzle. It is possible to perform operations such as progress or stagnation, progress speed, progress through an elbow, and backward movement.

In this way, the inside of the pipe can be cleaned without disassembly and disassembly of the pipe at the top of the scrubber. When cleaning is completed, the nozzle moves backward from the pipe 20 to come out, and the roller 600 reversely rotates the cable to a required extent to move the nozzle backward. The backward traveling process of the nozzle can also proceed while observing the field of view through the endoscope camera, and the passage of the elbow part proceeds smoothly due to the presence of the elastic part of the nozzle head part, as in the case of forward movement.

A fixing member for fixing the cable and the elastic part is mounted at the end of the elastic part 240 of the nozzle head part 200, and various members including the rear spray nozzle can be replaced in the nozzle head part as needed.

As described above, according to the present invention, cleaning can be performed by inserting a nozzle into the pipe and spraying high-pressure water in the place where the scrubber is located without disassembly and disassembly of the scrubber pipe.

The above embodiment can be slightly modified. For example, if there is a water supply facility near the scrubber, the water tank can be omitted and the faucet can be connected to the high-pressure hose. In this case, there is a possibility that the pump may also be omitted. That is, the high-pressure water supply unit capable of supplying high-pressure water to the nozzle of the nozzle head unit may be present in any form, and the water bottle does not necessarily need to be present.

In addition, there is a possibility that the collection box may be omitted as there is a drainage facility nearby.

A nozzle support in the form of a screw with multiple blades can also be transformed into a support with rollable balls or rollers. That is, a supporter equipped with a rollable ball or roller may be applied to an annular body that may be mounted at the end of the nozzle.

In addition, the display system of the display unit may be interlocked with a mobile terminal such as a smart phone or tablet computer of an operator, and a remote control module may be installed so that the pipe cleaning system can be turned on/off by the mobile terminal. In this case, the image of the endoscope camera and the cable running distance by the distance measuring device are displayed on the mobile terminal, so that the operator can operate one or more scrubber pipe cleaning systems almost simultaneously.

In addition, as the number of scrubber pipe cleaning increases, all variables such as pipe internal images, nozzle control pressure, delay time, and cable progression speed are all databased, and machine learning is performed by interlocking them to determine the pipe internal image and cable location. It will be possible to convert nozzle pressure, delay time, and progress speed to artificial intelligence automatic control as basic variables.

On the other hand, although this embodiment has described the pipe cleaning of the scrubber exhaust line, cleaning of the vacuum pump exhaust line of other semiconductors, displays, and various coating equipment can also be performed by the pipe cleaning system of the present invention.

In particular, it can be applied to cleaning of pipes connected to the scrubber in the vacuum pump exhaust line.
