[0046] The application also provides a use method of the glass steel stirring tank leak detection device, which comprises the following steps:

[0047] S1, pre-sealing treatment, before the tank body is produced and used, the valve body is closed, the feeding cover is sealed with the tank body, and the position between the feeding cover and the tank body is locked through the gate valve;

[0048] S2, leak detection, the external gas conveying equipment continuously conveys gas into the tank body through the gas inlet pipe, whether the tank body has a leak is detected, when the tank body has a leak, the gas pressure in the tank body is increased to drive the piston piece to move towards the blocking piece side and to move above the exhaust hole for exhaust, the piston piece is moved to drive the top column to move upwards, the first conductive piece is contacted with the second conductive piece, the circuit is conducted to make the signal lamp emit light, that is, the tank body does not have a damage leak, otherwise, there is a leak;

[0049] S3 Leakage Point Coarse Location: When a leak is found in the tank, the transmission assembly drives each rotating component to rotate, causing the movable component to move to the lowest point of the outer wall of the tank. Then, through the angle adjustment components, the angle of the corresponding sealing component is changed, and it cooperates with the sealing component on the movable component to form a ring shape that abuts against the outer wall of the tank, sealing the annular area of ​​the tank. External gas supply equipment continuously supplies gas into the tank. When the indicator light is on, the leak area of ​​the tank is within the current annular area; otherwise, it is not within the area. The transmission assembly drives the movable component to move sequentially to detect the approximate leak location of the tank.

[0050] The S4 leak precision positioning system detects the approximate leak location of the tank and then sequentially drives each angle adjustment component to separate the seal from the outer wall of the tank. Once the seal is separated, the indicator light goes out, confirming that the location is the accurate leak location of the tank.

[0051] The fiberglass mixing tank leak detection device of the present invention has the following advantages over the prior art:

[0052] (1) The external gas supply equipment delivers gas into the tank through the inlet pipe. As the internal gas pressure of the tank increases, the gas pressure will push the movable part of the pressure relief component to move above the exhaust port to relieve pressure. This allows for overall leakage detection of the tank. The corresponding seals are made to abut against the outer wall of the tank by the angle adjustment components and form a ring shape with the seals on the moving part of the linear adjustment component. This allows for leakage detection of the ring area of ​​the tank. The ring structure is moved along the vertical direction of the tank by the linear adjustment component, allowing for a rough detection of the leakage location of the tank. Furthermore, by sequentially driving the angle adjustment components, the seals are separated from the outer wall of the tank. When the signal light goes out after separation, the exact leakage location of the tank is determined. Thus, this device can detect leakage of the fiberglass mixing tank and identify the specific location of the damage or crack, facilitating the repair of the fiberglass tank.

[0053] (2) During the leak detection, the piston moves and the top column moves upward, so that the first conductive part contacts the second conductive part, and the circuit is connected to make the indicator light light up, which can intuitively show the leakage situation inside the tank and facilitate direct observation by the staff.

[0054] (3) The device is applicable to leak detection before tank production, and also meets the requirements for leak detection during tank production. It can continuously detect the leakage of the tank during production. When the leak is detected, the leak can be plugged immediately to avoid causing significant economic losses.

[0069] It should be noted that the number of support pieces 11 and lug blocks 12 in the embodiment is four, and the four support pieces 11 and lug blocks 12 are arranged in a ring-shaped array, and the array distribution of the support pieces 11 can stably install the tank body 1 on the ground; by opening the feeding cover 13, the materials to be mixed and stirred can be added into the tank body 1, and then the feeding cover 13 is locked in position with the tank body 1 by the gate valve 14, which is suitable for solid materials to be put and stirred; in another embodiment, a plurality of feeding pipes are fixedly installed on the side of the tank body 1 away from the ground, each feeding pipe is connected with the inside of the tank body 1, and each feeding pipe is provided with a feeding valve, the other end of the feeding pipe is connected with the liquid supply equipment outside, and at the same time, a corresponding counterweight system can be provided to transport materials with a specified specific gravity into the tank body 1 for stirring, and the feeding valve can cut off the feeding pipe and the liquid supply equipment outside, which is suitable for liquid materials to be transported and stirred, and the mixed materials in the tank body 1 can be discharged by opening the valve body 15, and this part of the structure is prior art and will not be described here.

[0070] The air inlet pipe 2 of the embodiment is arranged on the side of the tank body 1 away from the ground and is connected with the inside of the tank body 1 for conveying gas into the tank body 1.

[0071] It should be noted that one end of the air inlet pipe 2 extends to the inside of the tank body 1, and the other end is connected with the external gas supply device, and the gas delivered by the external gas supply device can be hot gas or cold gas, wherein the delivered gas can be set according to the mixing and stirring requirements between the materials.

[0072] The exhaust cylinder 3 of the embodiment is arranged on the side of the tank body 1 away from the ground and is connected with the inside of the tank body 1, and the outside of the exhaust cylinder 3 is provided with exhaust holes 300; the pressure relief assembly 4 is arranged in the exhaust cylinder 3, and the pressure relief assembly 4 has a movable part that can move linearly along the axial direction of the exhaust cylinder 3, and the movable part moves linearly to the exhaust holes 300 to relieve the pressure of the gas in the tank body 1.

[0073] It should be noted that the gas delivered by the external gas supply device enters the tank body 1 through the air inlet pipe 2, and under the condition that the tank body 1 has no leakage, as the internal gas pressure of the tank body 1 increases, the gas pressure will drive the movable part of the pressure relief assembly 4 to move towards the side of the exhaust holes 300, and the exhaust holes 300 will be connected with the inside of the tank body 1 for pressure relief, which can detect the leakage of the tank body 1.

[0074] As a preferred embodiment, the pressure relief assembly 4 in the embodiment includes a piston 41, a blocking piece 42, a top column 43, and a resilient piece 44, wherein the piston 41 is slidingly connected to the inside of the exhaust cylinder 3, and the outside wall of the piston 41 abuts against the inside wall of the exhaust cylinder 3, and the piston 41 serves as the movable part of the pressure relief assembly 4; the blocking piece 42 is fixedly arranged on the inside of the exhaust cylinder 3 and located on the side of the piston 41 away from the tank body 1, and the blocking piece 42 is provided with a guide hole 420; the top column 43 is fixed on the side of the piston 41 close to the blocking piece 42 and slidingly connected in the guide hole 420 and extends outwardly through the guide hole 420; and the resilient piece 44 is sleeved on the outside of the top column 43, and the two side ends of the resilient piece 44 abut against the side end faces opposite to the piston 41 and the blocking piece 42, respectively.

[0075] It should be noted that as the internal gas pressure of the tank body 1 increases, the gas pressure will drive the piston 41 to move towards the side of the blocking piece 42, and the piston 41 moves above the exhaust holes 300, thereby making the exhaust holes 300 connected with the inside of the tank body 1 for pressure relief, and in the moving process, the top column 43 slides in the guide hole 420 to guide the movement of the piston 41, and at the same time, the piston 41 moves to compress the resilient piece 44 to a stressed and compressed state, and when the pressure in the tank body 1 decreases, the resilient piece 44 removes the pressure to drive the piston 41 to reset.

[0076] Specifically, the number of the exhaust holes 300 in the embodiment is several, and the several exhaust holes 300 are distributed in a ring-shaped equidistant array with the axis of the exhaust cylinder 3 as the center, and the exhaust holes 300 are located between the piston 41 and the blocking piece 42.

[0077] It should be noted that when the upper surface of the piston member 41 is in close contact with the lower surface of the blocking member 42, the lower surface of the piston member 41 is above the exhaust hole 300 at this time, avoiding the piston member 41 from blocking the position of the exhaust hole 300 when moving to the topmost position.

The sealing member 7 is arranged on the side of the moving part of the linear adjustment assembly 5 and the adjustment part of the angle adjustment assembly 6 close to the tank body 1. The adjustment part makes the corresponding sealing member 7 abut against the outer wall of the tank body 1, forming a ring shape to detect the leakage of the side wall of the tank body 1 in this area.

[0080] It should be noted that the corresponding sealing member 7 abuts against the outer wall of the tank body 1 through the angle adjustment assembly 6, and cooperates with the sealing member 7 on the moving part of the linear adjustment assembly 5 to form a ring shape, thereby detecting the leakage of the ring-shaped area of the tank body 1.

[0081] As a preferred embodiment, the linear adjustment assembly 5 in the embodiment includes a rotating member 51, a movable member 52, a guide member 53, and a transmission assembly 54. The rotating member 51 is rotatably connected between the support member 11 and the corresponding ear block 12 through a bearing, and one end of the rotating member 51 extends through the support member 11 and is arranged to extend towards the ground side. The movable member 52 is threadedly connected to one side of the rotating member 51, and the movable member 52 serves as the movable part of the linear adjustment assembly 5. The guide member 53 is fixed between the support member 11 and the corresponding ear block 12, and one end of the guide member 53 extends through the movable member 52 and is slidably connected to the movable member 52. The transmission assembly 54 is arranged between the outer sides of the ends of the rotating members 51 extending out of the support member 11, and is used to drive the rotating members 51 to rotate synchronously and in the same direction.

[0082] It should be noted that the number of straight adjusting assemblies 5 in the embodiment is four, and the four rotating members 51 are simultaneously and synchronously rotated by the transmission assembly 54.

The output end of the driving member 543 is fixedly connected with the corresponding rotating member 51, and is used to drive the rotating member 51 to rotate circumferentially.

[0084] It should be noted that the driving member 543 drives the connected rotating member 51 to rotate, and the plurality of transmission members 541 are synchronously rotated through the transmission members 541 and the transmission belt 542, so that the four rotating members 51 are synchronously and synchronously rotated.

[0085] It can be understood that the transmission member 541 can be a chain wheel or a transmission wheel, and the transmission belt 542 can be a chain or a belt. The chain wheel is used in cooperation with the chain, and the transmission wheel is used in cooperation with the belt.

[0086] As a preferred embodiment, the angle adjusting assembly 6 in the embodiment includes an arc-shaped member 61 and a telescopic member 62. The movable member 52 is provided with an avoiding slot 520 on both sides in the radial direction of the rotating member 51. One end of the arc-shaped member 61 extends into the avoiding slot 520 and is hingedly connected with the movable member 52. The telescopic member 62 has a movable end and a fixed end. The movable end is hingedly connected with the outer wall of the arc-shaped member 61, and the fixed end abuts against the side wall of the movable member 52. The telescopic member 62 is adjusted in extension and retraction to change the angle of the arc-shaped member 61.

[0087] It should be noted that since the two ends of the telescopic member 62 are hingedly connected with the movable member 52 and the arc-shaped member 61 respectively, the extension and retraction of the movable end of the telescopic member 62 can adjust the extension posture of the arc-shaped member 61, so that the sealing member 7 can abut against the outer wall of the tank body 1.

[0088] The avoiding slot 520 can prevent the end of the arc-shaped member 61 hingedly connected inside the movable member 52 from being disturbed during movement, thereby ensuring the stability of the rotation of the arc-shaped member 61.

[0089] Specifically, the telescopic member 62 in the embodiment can be one of a pneumatic cylinder, an oil cylinder, and an electric cylinder.

[0090] In order to facilitate detection of people observing the leakage of the tank 1, the embodiment also provides an indication component 8, the indication component 8 includes a signal lamp 81, a power supply 82, a first conductive part 83 and a second conductive part 84, wherein the signal lamp 81 is fixedly arranged at the end of the exhaust cylinder 3 away from the tank 1; the power supply 82 is fixedly arranged on the inner wall of the exhaust cylinder 3, and is arranged opposite to the position of the blocking part 42; the first conductive part 83 and the second conductive part 84 are both arranged on the side of the power supply 82 close to the blocking part 42, and the second conductive part 84 has an elastic reset property and does not abut against the first conductive part 83 in the initial position; the output end of the power supply 82 is electrically connected with the first conductive part 83, the second conductive part 84 is electrically connected with the input end of the signal lamp 81, and the output end of the signal lamp 81 is electrically connected with the input end of the power supply 82; when the exhaust is normal, the piston part 41 drives the top column 43 to make the second conductive part 84 elastically deformed and contact the first conductive part 83, and the circuit is conducted to make the signal lamp 81 emit light.

[0091] It should be noted that when there is no leakage and damage in the tank 1, the piston part 41 pushes the top column 43 to move upward, the top column 43 moves upward to press and deform the second conductive part 84 to contact the first conductive part 83, so that the power supply 82 supplies power to the signal lamp 81 to make it emit light, reminding that there is no leakage in the tank 1; when leakage and damage occur in the tank 1, the signal lamp 81 does not emit light all the time when the gas supply equipment continuously supplies gas to the tank 1, which proves that leakage occurs in the tank 1.

[0092] The sealing parts 7 in the embodiment are fixed on the sides of the movable parts 52 and the arc-shaped parts 61 close to the tank 1; the other side of the sealing part 7 arranged on the movable part 52 abuts against the outer wall of the tank 1; and when the sealing part 7 on the arc-shaped part 61 abuts against the outer wall of the tank 1, the side surface thereof abuts against the surface adjacent to the adjacent sealing part 7.

[0093] Specifically, the sealing part 7 can be made of rubber or silica gel.

[0094] As shown in Figure 8 The application also provides a use method of the glass steel stirring tank leakage detection device, which comprises the following steps:

[0095] S1, pre-sealing treatment, before the tank 1 is produced and used, the valve body 15 is closed, the feeding cover 13 is sealed with the tank 1, and the position between the feeding cover 13 and the tank 1 is locked through the gate valve 14;

[0096] S2 leak detection, the outside gas supply equipment continuously sends gas to the tank 1 through the gas inlet pipe 2, and detects whether the tank 1 leaks. When the tank 1 leaks, the gas pressure in the tank 1 increases, pushing the piston 41 to move towards the blocking piece 42, and moving to the exhaust hole 300 to exhaust. The piston 41 moves upwards, driving the top column 43 to move upwards, so that the first conductive piece 83 and the second conductive piece 84 are in contact, the circuit is conducted, and the signal lamp 81 emits light. If the tank 1 does not leak, the signal lamp 81 does not emit light.

[0097] It should be noted that the outside gas supply equipment continuously sends gas to the tank 1 through the gas inlet pipe 2. When the gas pressure in the tank 1 reaches 0.8-1.0 MPa, the tank 1 is in a sealed state. At this time, the gas pressure in the tank 1 increases, pushing the piston 41 to move towards the blocking piece 42, ensuring that the tank 1 can normally release pressure.

[0098] S3 coarse positioning of the leakage point. When the tank 1 leaks, the transmission assembly 54 drives each rotating piece 51 to rotate, moving the movable piece 52 to the lowermost end of the outer wall of the tank 1. Then, through the angle adjusting assembly 6, the angle of the corresponding sealing piece 7 is changed, and the sealing piece 7 on the movable piece 52 is cooperated to form a ring shape and abut on the outer wall of the tank 1, sealing the ring-shaped area abutting on the tank 1. The outside gas supply equipment continuously sends gas to the tank 1. When the signal lamp 81 emits light, the leakage area of the tank 1 is in the current ring-shaped area, otherwise it is not in the area. By driving the movable piece 52 to move in sequence through the transmission assembly 54, the coarse leakage position of the tank 1 is detected.

[0099] It should be noted that the distance moved by the transmission assembly 54 each time the movable piece 52 moves is equal to the height of the sealing piece 7. When the movable piece 52 moves to the lowermost end of the outer wall of the tank 1, the bottom edge of the movable piece 52 coincides with the bottom edge of the tank 1. During the leak detection, the angle adjusting assembly 6 makes the corresponding sealing piece 7 abut on the wall of the tank 1, and the abutting time is 3-5 min. At this time, the outside gas supply equipment continuously sends gas to the tank 1 through the gas inlet pipe 2. When it is detected that the leakage area is in the current ring-shaped area, the sealing pieces 7 are opened in sequence through the angle adjusting assembly 6 in counterclockwise order. The signal lamp 81 emits light, and the minimum range area of the leakage point on the tank 1 is determined.

[0100] S4 fine positioning of the leakage. After detecting the coarse leakage position of the tank 1, the angle adjusting assembly 6 is driven in sequence to separate the sealing piece 7 from the outer wall of the tank 1. When the signal lamp 81 is extinguished after separation, it is determined that the position is the accurate leakage position of the tank 1.

[0101] It needs to be explained that considering that part of the material needs to be stirred in the tank 1 for a long time, the embodiment can also continuously detect the leakage of the tank 1 during the production process. When the leakage of the tank 1 is detected, the leakage of the tank 1 can be plugged in the first time to avoid causing great economic loss.

[0102] Wherein, before the tank 1 leakage detection starts, it is needed to judge whether the stirring motor of the tank 1 is in the running state. If the stirring motor is in the running state, it is obtained that the tank 1 in this case is in the production state, and vice versa, it is obtained that the tank 1 in this case is in the production stop state.

[0103] For the tank 1 in the production state, the opening and closing of the driving part 543 can be selectively started by system control or manually forced to open and close. When the leakage point of the tank 1 in the production is below the liquid level, the staff knows that the signal lamp 81 is turned off after determining the leakage point of the tank 1. The determination of the leakage point below the liquid level is that the liquid will flow out from the leakage point because the tank 1 is filled with liquid. Then the staff can manually drive the opening and closing of the driving part 543. The driving part 543 drives the movable part 52 to move to the height position of the leakage point, and then drives the sealing part 7 to abut against the outer wall of the tank 1 through the angle adjusting assembly 6 corresponding to the position of the leakage point, thereby temporarily plugging the tank 1, providing sufficient time for the maintenance personnel.

[0104] When the leakage point of the tank 1 is above the liquid level, the opening and closing of the driving part 543 is selected to be controlled by the system, so that the movable part 52 moves to detect the leakage point of the outer wall of the tank 1 in turn.

[0105] When the tank 1 is in the production stop state and there is no mixed liquid inside, the opening and closing of the driving part 543 is selected to be controlled by the system, so that the movable part 52 moves to detect the leakage point of the outer wall of the tank 1 in turn.

[0106] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
