[0026] All terms used in the present disclosure have the same meaning as understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as those, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.
[0027] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be regarded as part of the specification.
[0028] Reference Figure 1 , the present disclosure provides a plugging device, including: a liquid-cooled main body 1, the liquid-cooled main body 1 includes a plugging end 2 and a mounting end 3, the liquid-cooled main body 1 gradually expands outward along the direction from the plugging end 2 to the mounting end 3, the inside of the liquid-cooled main body 1 is hollow to form a cooling cavity 4 for accommodating a coolant, and the plugging end 2 can be inserted into the pore to be plugged; a liquid inlet pipe 5, one end of the liquid inlet pipe 5 is communicated with the cooling cavity 4, and the other end is communicated with a coolant supply device; a liquid outlet pipe 6, one end of the liquid outlet pipe 6 is communicated with the cooling cavity 4, and the other end is communicated with a coolant collection device. The water-cooled main body includes a housing 7 and a cover plate 8, the housing 7 and the cover plate 8 are fixedly and hermetically connected, the end where the cover plate 8 is located is the mounting end 3, and the end of the housing 7 far from the cover plate 8 is the plugging end 2. The coolant supply device is a water tank and a circulation pump, the circulation pump is connected to the liquid inlet pipe 5, the coolant collection device is also a water tank, the water tanks of the coolant supply device and the coolant collection device can be connected, and a heat dissipation structure or a refrigeration device (wherein the heat dissipation structure and the refrigeration device adopt the prior art) can be provided on the pipeline connecting the two. The coolant can preferably be water, and water has low cost and a large specific heat capacity.
[0029] Taking the plugging of the furnace wall of a glass furnace as an example, the plugging end 2 of the liquid-cooled main body 1 is the end directly in contact with the leakage position of the glass furnace tank wall. The shape of the liquid-cooled main body 1 is set to gradually become larger along the direction from the plugging end 2 to the mounting end 3, which is convenient for the plugging end 2 to be smoothly inserted into the inside of the leakage part, so as to directly cool the high-temperature glass liquid inside the leakage part, make it quickly solidify to form solid glass, so as to realize the rapid plugging of the leakage part, and the solidified glass can further plug the inside of the leakage part and isolate the high-temperature glass liquid, so that the inside of the leakage part is not easily contacted with the high-temperature glass liquid again, thereby avoiding the situation that the leakage part is still in long-term contact with the high-temperature glass liquid and causing further expansion of the leakage part, and making the plugging effect better.
[0030] In some embodiments, the housing 7 is an integrally formed part, and the housing 7 is a wedge-shaped structure or a conical structure. The housing 7 is preferably integrally processed by machining or casting using a metal material, and the method of processing by welding plates is avoided, so as to avoid the problem of cracking of the housing 7 during the use of the liquid-cooled main body 1 to the greatest extent, and the service life of the liquid-cooled main body 1 can be extended. The furnace wall of a glass furnace is usually built with refractory bricks, and the gaps between the refractory bricks are easily eroded parts. Due to the different gap positions, the shapes of the leakage positions caused by erosion are also different. When the gap between the refractory bricks face to face is corroded, the shape of the leakage position is approximately rectangular, and a liquid-cooled main body 1 with a wedge-shaped structure can be selected for plugging; when the gap between the corners of the refractory bricks is corroded, the shape of the leakage position is approximately circular, and a liquid-cooled main body 1 with a conical structure is selected for plugging.
[0031] Reference Figure 1, in some embodiments, both the liquid inlet pipe 5 and the liquid outlet pipe 6 extend into the cooling cavity 4 from the cover plate 8. The distance from the port at the end of the liquid inlet pipe 5 extending into the cooling cavity 4 to the cover plate 8 is 2 / 3 or more of the distance from the plugging end 2 to the cover plate 8. The distance from the port at the end of the liquid outlet pipe 6 extending into the cooling cavity 4 to the cover plate 8 is less than 20 mm. The length of the part of the liquid inlet pipe 5 extending into the cooling cavity 4 is much longer than the length of the part of the liquid outlet pipe 6 extending into the cooling cavity 4. After the coolant flows into the cooling cavity 4 from the liquid inlet pipe 5, the coolant can start to flow from the deep part (plugging end) of the cooling cavity 4. The plugging end 2 is the direct contact part with the leakage position. It is preferred to ensure that the coolant introduced into the cooling cavity starts to flow from the plugging end 2 first, so that the plugging end can quickly cool and solidify the glass liquid at the leakage position, preventing the glass liquid from further eroding the kiln wall. Affected by the pressure, the coolant flows out towards the direction of the liquid outlet pipe 6. Since the part of the liquid outlet pipe 6 extending into the cooling cavity 4 is short, the coolant can flow through the entire cooling cavity 4 more completely, making full use of the heat exchange between the coolant and the housing 7 to reduce the temperature of the housing 7. During the manual operation of the staff, the liquid inlet pipe 5 should be above the liquid outlet pipe 6 in the height direction. The coolant enters the cooling cavity 4 from the liquid inlet pipe 5 on one side of the plugging end 2. After absorbing the heat conducted from the housing 7, the temperature of the coolant rises and its density becomes smaller, so it floats upwards in the cooling cavity 4 and is squeezed towards the liquid outlet pipe 6 located below the cooling cavity under the push of the subsequently flowing coolant. Through this process, the coolant can exchange heat with the housing 7 in the cooling cavity 4 to the greatest extent, improving the utilization rate of the coolant.
[0032] In some embodiments, both the liquid inlet pipe 5 and the liquid outlet pipe 6 include a hard pipe section 9 and a flexible pipe section 10, so as to be fixedly connected to the cover plate 8 via the hard pipe section 9, and the flexible pipe section 10 is hermetically connected to the part of the hard pipe section 9 extending out of the cooling cavity 4. The hard pipe section 9 is the grasping position for the staff to operate the liquid cooling body 1 for plugging. Due to the deformable characteristic of the flexible pipe section 10, it is convenient to adjust the position of the liquid cooling body 1.
[0033] In some embodiments, the outer wall of the hard pipe section 9 is coated with an insulating layer (coated with insulating tape or rubber sleeve), and the flexible pipe section 10 is an insulating flexible pipe, and the insulating flexible pipe can be a rubber pipe. The glass liquid in the glass melting furnace with the electro - melting - assisting function is charged, and the insulating layer effectively prevents the occurrence of safety accidents.
[0034] In some embodiments, a solenoid valve 11 may be provided at the end of the flexible hose section of the liquid outlet pipe. A temperature sensor is also provided in the cooling chamber 4. The temperature sensor is in signal connection with the solenoid valve 11, and the solenoid valve 11 is configured to adjust its opening degree according to the temperature signal detected by the temperature sensor. The temperature sensor controls the opening degree of the solenoid valve 11 by monitoring the temperature of the coolant in the cooling chamber 4. The higher the temperature of the coolant, the larger the opening degree of the solenoid valve 11; the lower the temperature, the smaller the opening degree of the solenoid valve. The temperature of the coolant is always controlled below 50 °C to ensure the heat exchange efficiency of the coolant. The temperature sensor may also be in signal connection with the circulation pump in the coolant supply device. The higher the temperature of the coolant, the faster the circulation pump pumps water; the lower the temperature, the slower the circulation pump pumps water.
[0035] In some embodiments, the specific operation steps of the present disclosure are as follows: when it is found that there is a leakage in the pool wall of the glass furnace, the staff holds the rigid pipe section 9 of the present disclosure, opens the coolant supply device so that the entire cooling chamber 4 is filled with coolant, and inserts the plugging end 2 of the liquid cooling body 1 into the leakage position until it is completely plugged, effectively controlling the leakage position and providing a good working environment for subsequent repairs.
