[0021] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0022] See also Figure 1 to Figure 6 A device for detecting liquid leakage in a high-temperature oven comprises a pipe 1, a joint 2 and a detection mechanism. One side of the pipe 1 is connected to an oven 11 through a right-angle joint 10. When liquid leakage occurs in the oven 11, the leaked liquid flows into the pipe 1 through the right-angle joint 10. The other side is connected to the detection mechanism through the joint 2. The detection mechanism comprises a fixing seat 3. The fixing seat 3 is provided with a sealing gasket 4. The sealing gasket 4 is fixed in the fixing seat 3 through a fixing plate 7. Preferably, the fixing plate 7 is fixedly connected to the top of the fixing seat 3 through two screws. The fixing seat 3 is provided with a first conductive screw 5 and a second conductive screw 6. The first conductive screw 5 passes through the sealing gasket 4 and is fixed with a nut, and is externally connected to a positive electrode 91 of a liquid leakage detection belt. The second conductive screw 6 passes through the sealing gasket 4 and is fixed with a nut, and is externally connected to a negative electrode 92 of a liquid leakage detection belt.
[0023] Preferably, the pipe 1 is a hollow cylindrical structure, so that the leaked liquid is more likely to accumulate at the bottom, thereby increasing the sensitivity of the detection mechanism.
[0024] Specifically, the positive electrode 91 of the liquid leakage detection belt and the negative electrode 92 of the liquid leakage detection belt are both conductive wires.
[0025] Specifically, the first conductive screw 5 passes through the sealing gasket 4, and a nut is provided above the top and above the bottom to fix the first conductive screw 5 to the sealing gasket 4; the second conductive screw 6 passes through the sealing gasket 4, and a nut is provided above the top and above the bottom to fix the second conductive screw 6 to the sealing gasket 4.
[0026] Preferably, the joint 2 is a three-way joint, and the bottom of the joint 2 is a horizontal structure, so that the leaked liquid is at a horizontal height, to avoid that when the leak occurs in the furnace 11 and flows to the bottom of the joint 2 through the pipeline 1, the leaked liquid cannot cause a short circuit in the leakage detection belt due to the different heights, and thus cannot sound an alarm.
[0027] One end of the bottom of the connector 2 is connected to the pipe 1, preferably, the plug 8 is at the interface with the connector 2, and the other end of the bottom is provided with a plug 8 for sealing the connector 2, the top end of the connector 2 is connected to the fixing seat 3, and the plug 8 matches the inner diameter of the interface of the connector 2. Preferably, the plug 8 and the interface of the connector 2 are fixed by an interference fit to prevent liquid from flowing out of one end of the connector 2. After use, the plug 8 is removed to discharge the leaked liquid inside the connector 2.
[0028] The bottom of the first conductive screw 5 and the second conductive screw 6 are located in the joint 2, and the bottom of the first conductive screw 5 and the bottom of the second conductive screw 6 are located on the same horizontal line to avoid the first conductive screw 5 and the second conductive screw 6 being unable to connect and conduct when they are at different heights. The sensitivity of the leakage detection belt is related to the height of the bottom of the conductive screw from the joint 2. The closer the distance between the bottom of the first conductive screw 5 and the bottom of the second conductive screw 6 and the joint 2 is, the higher the sensitivity of the leakage detection belt is.
[0029] The fixing seat 3 is installed at the upper end of the joint 2, and a through hole is provided inside the fixing seat 3. Preferably, there are two through holes, the diameter of the through hole at the top is larger than the diameter of the through hole at the bottom, the outer diameter of the fixing seat 3 is larger than the outer diameter of the joint 2, and the diameter of the through hole at the bottom is smaller than the outer diameter of the joint 2, so that the fixing seat 3 can be fixed at the upper end of the joint 2.
[0030] The sealing gasket 4 is an insulating sealing gasket, which insulates the first conductive screw 5 and the second conductive screw 6 from the oven to avoid short circuit caused by contact with the oven and false alarm.
[0031] The positive electrode 91 and the negative electrode 92 of the liquid leakage detection belt are electrically connected to the oven alarm. When the liquid leakage detection belt is short-circuited, an electrical signal is sent to the oven alarm, causing the oven alarm to sound an alarm.
[0032] Working principle:
[0033] If there is coolant leakage in the high-temperature oven, the coolant flows into the pipe 1 through the right-angle joint 10, and flows along the pipe 1 to the joint 2. When the coolant reaches a certain height, the first conductive screw 5 and the second conductive screw 6 are connected and conducted by the coolant, and then the positive electrode 91 of the leakage detection belt and the negative electrode 92 of the leakage detection belt are short-circuited and an electrical signal is triggered. After receiving the electrical signal, the oven alarm sends out a leakage alarm. After the alarm is lifted, the plug 8 is removed to discharge the coolant inside the joint 2 and the pipe 1.
[0034] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
