First, the inner wall of the lining tank 10 is treated with a fluororesin lining 12.

The vent hole 11 is composed of a pipe having a screw thread formed on the inner circumferential surface and is installed by welding while penetrating the lining tank 10 so that the end is close to the fluororesin lining 12. Therefore, when the fluororesin lining 12 is damaged by the chemical reaction of the chemical, the liquid generated from the chemical leaks through the vent hole 11.

The leak detection member 100 includes a sensor body 110 in which an internal space is formed, a mounting part 120 formed on the sensor body 110 and mounted in the vent hole 11 of the lining tank 10, and a lining tank ( 10) includes a detection sensor unit 130 for detecting leakage leaking through the vent hole 11, and a leak display unit 140 for displaying a location when detection information is generated by the detection sensor unit 120.

First, the internal space formed in the lining tank 10 is filled with chemicals such as acid, alkali, waste, and the like.

In the sensor body 110, an inner space is opened on one side and a cable connected to the controller 200 to be described later passes through the other side. The closing plate 111 is coupled to one side of the sensor body 110 with a bolt or the like, so that the inner space of the sensor body 110 can be closed. The cable is detachably connected to the sensor controller 150 through a terminal and a socket.

The mounting portion 120 is composed of a pipe having a screw thread formed on the outer circumferential surface so as to be coupled to the lining tank 10. This mounting portion 120 is formed to pass through the closing plate 111 that closes the sensor body 110 . And it may be formed to penetrate directly into the sensor body 110.

As the conductive pattern is formed, it is electrically connected to the sensor control unit 150 and detects liquid or gaseous leakage generated from a chemical solvent, which is a chemical substance.

When the end of the fluororesin lining 12 is damaged, the sensor pin 131 contacts the leaked fluid through the vent hole 11, so that the leaked fluid can be immediately detected.

The fixing block 132 is forcibly inserted into the mounting portion 120 and fixed, and the fixing holes 132a into which the sensor pins 131 are respectively inserted and fixed are distributed. This fixing block 132 can be closed by being fixed to the mounting part 120 . When the sensor pins 131 are inserted into and fixed to the fixing holes 132a of the fixing block 132, they are kept spaced apart from each other and can be forcibly separated and replaced with new products without interfering with each other.

The leak display unit 140 is controlled by the sensor control unit 150 to be described later in a state provided on the outside of the body 110 and consists of an LED displaying light or an alarm displaying sound. Therefore, the manager can visually check the light displayed by the leak display unit 140 or listen to the sound to check the corresponding leak detecting member 100 that detected the chemical leak.

The socket 152 is formed in such a way that the sensor pins 131 of the detection sensor unit 130 are inserted and connected to each other through dispersive connection holes.

Therefore, in a state in which the sensor pins 131 pass through the fixing block 132 and are fixed, the fixing block 132 is forcibly inserted into the mounting part 120 to be fixed.

Then, while inserting the sensor pins 131 into the socket 152 of the sensor controller 150, the closing plate 111 is coupled to the sensor body 110.

In this state, the leak detection member 100 is mounted in the vent hole 11 of the lining tank 10.

In addition, the sensor controller 150 may be operated and controlled by power supplied from the controller 200 through a wire. In addition, when the sensor control unit 150 is wirelessly controlled by the controller 200, a battery supplying power to the sensor control unit 150 may be built into the inner space of the sensor body 110.

In addition, the leakage detection member 100 includes a sensor body 110, a mounting part 120, a detection sensor part 130, a leakage display part 140, and a sensor control part 150.

A flange fixed to the mounting portion 120 is formed around the end. Since the sensor sheet 133 is forcibly inserted into the mounting portion 120 and fixed, it can be forcibly separated and replaced with a new product.

Also, the flange of the sensor sheet 133 may be close to the fluororesin lining 12 .

Therefore, when the sensor sheet 133 is forcibly inserted into the mounting portion 120, the connection pin 134 protrudes through the closing plate 111 of the sensor body 110.

The sensor control unit 150 includes an information processing unit 151 and a socket 152.

The information processing unit 151 is configured in the same manner as described above, and detailed description thereof will be omitted. The socket 152 is formed with spaced apart connection holes through which the connection pins 134 are inserted and connected.

Therefore, when the closing plate 111 is coupled to the sensor body 110, the connection pins 134 are inserted into the connection holes of the socket 152 to be connected.

The leak detection member 100 configured as described above may be configured in plurality and installed in a distributed manner in the upper, middle, lower, left, and right directions in the lining tank 10.

The controller 200 includes an information verification unit 210 that checks the leakage detection information and ID information provided by the leakage detection member 100, and a leakage detection member 100 corresponding to the ID information confirmed by the information verification unit 210. ) Includes a location display operation unit 220 that operates the leak display unit 140 and an information transmission unit 230 that transmits leak detection information and ID information confirmed by the information confirmation unit 210 to an external management server do.

The management server is provided in the control center and is managed by an administrator.

Accordingly, when the leak detection information and the ID information are transmitted to the management server by the controller 200, the manager of the control center can recognize which leak detection member 100 has detected the leak.

And the controller 200 includes a location information management unit 240 that matches, stores, and manages sensor location information and ID information for the location where the leak detection member 100 corresponding to the ID information is installed in the lining tank 10. .

The sensor location information is information about the upper, middle, lower, front, rear, left, and right positions of the leak detection member 100 installed in the lining tank 10. Furthermore, the sensor location information may be set in detail as up, front (top to front), middle, back (middle to back).

Therefore, since the sensor location information is provided along with the ID information, the manager can quickly check the location of the leak detection member 100 that detects the leak in the relatively large and bulky lining tank 10.

That is, since it is known whether the corresponding leak detection member 100 is located at the top or the front of the lining tank 10, the corresponding leak detection member 100 can be found more quickly. As a result, quick action can be taken, and leakage of the leaked liquid through the vent hole 11 of the lining tank 10 can be prevented in advance.

In addition, as shown in FIGS. 8 to 11, the sensor body 110 is formed with through-holes 112 through which the cable and the leak indicator 140 are installed on the other side.

Protrusions and grooves are formed on the sensor body 110 and the closing plate 111, and when the closing plate 111 is coupled to the sensor body 110, the projections are forcibly inserted into the grooves and coupled. That is, it can be conveniently combined in a one-touch format.

The detection sensor unit 130 includes a terminal substrate 135 electrically connected to the sensor control unit 150, a first terminal unit 136 electrically coupled to the terminal substrate 135, and interference with the first terminal unit 136. and a second terminal unit 137 electrically coupled to the terminal board 135 without being disconnected.

The terminal board 135 is coupled and electrically connected to the sensor control unit 150 by bolts and nuts, and a plurality of terminal holes 135a are formed to be spaced apart at regular intervals. A first fixed terminal 136c and a second fixed terminal 137c to be described later are fixed to these terminal holes 135a and electrically connected to the sensor controller 150 .

Here, the sensor control unit 150 has a plurality of leakage display units 140 fixed on the rear side and a cable socket to which cables are connected is formed, passing through the through-holes 112 of the sensor body 110, so that the sensor body ( 110) protrudes to the outside.

The first terminal unit 136 includes a plurality of first sensor pins 136a for detecting leakage, a first ring 136b connected while the first sensor pins 136a are spaced apart at regular intervals, and a first ring 136b. ) and a first fixed terminal 136c which is inserted into and fixed to the terminal hole 135a of the terminal board 135.

The first sensor pins 136a are spaced apart at regular intervals and arranged in a circular shape.

The first ring 136b has a ring shape as a plurality of pieces bent in an arc shape are connected to the first sensor pins 136a. At this time, the convex middle parts of the pieces face the inside of the ring shape (see Fig. 10a).

As the first fixed terminal 136c is formed to be bent, its end protrudes to the inside of the first ring 136b and is fixed to the terminal hole 135a on one side.

The second terminal unit 137 includes a plurality of second sensor pins 137a for detecting leakage, a second ring 137b connected while the second sensor pins 137a are spaced apart at regular intervals, and a second ring 137b. ) and a second fixed terminal 137c inserted into and fixed to another terminal hole 135a of the terminal substrate 135.

The second ring 137b forms a ring shape as a plurality of pieces bent in an arc shape are connected to the second sensor pins 137a. At this time, the convex middle parts of the pieces face the outside of the ring shape (see Fig. 10b).

As the second fixed terminal 137c is formed to be bent, its end protrudes to the inside of the first ring 136b and is fixed to the terminal hole 135a on the other side.

Therefore, when the first fixed terminal 136c and the second fixed terminal 137c are respectively fixed to the terminal holes 135a of the terminal substrate 135, the first ring 136b and the second ring 137b do not interfere with each other. While not interfering with each other, the first sensor pins 136a and the second sensor pins 137a are positioned between each other.

In this way, even when the first terminal unit 136 and the second terminal unit 137 are disposed together on the terminal board 135, they do not interfere with each other. In addition, the shape of the first ring 136b and the second ring 137b can be applied to a narrow space, thereby minimizing the overall size of the present invention.

It is a very useful invention because it can be displayed outside and alerted to the control center.

Those skilled in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing its technical spirit or essential features. Therefore, the embodiments described above should be understood as illustrative and not limiting in all respects, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and the meaning and scope of the claims and their All changes or modified forms derived from the concept of equivalence should be construed as being included in the scope of the present invention.
