Description

technical field

The invention belongs to the technical field of alarm devices, and in particular relates to a high-temperature liquid leakage alarm device for optical glass smelting.

Background technique

The melting temperature of optical glass is high and the time is long. As the production continues, the thickness of the kiln is too thin or is eroded, and high-temperature liquid leakage will occur. How to detect high-temperature liquid leakage as early as possible is the key to preventing safety accidents and reducing property. Therefore, it is particularly important to install a high-temperature liquid leakage alarm device.

Since the degree of erosion of refractory bricks is difficult to accurately control, it is difficult to locate when and where leakage will occur. At present, most manufacturers use the method of manual inspection of the furnace body to check whether there is any leakage. Based on experience, it can be inferred whether there is a possibility of local leakage, which can give an early warning, but it is highly dependent on experience and cannot be continuously inspected in an all-round way. . Some manufacturers also install thermocouples in places where leakage is prone to occur, and realize alarms by sensing temperature changes, which can quickly and accurately send out alarm signals. However, because thermocouples measure temperature on a point-to-point basis, the monitoring range is small, and the cost of large-scale installation is high. , the lines are complicated, and the feasibility of implementation is poor. Simultaneously, above-mentioned two kinds of warning methods all have hysteresis, can not take measures such as plugging, delaying, or reducing the amount of leakage when leakage occurs.

detailed description

Various exemplary embodiments, features, and aspects of the invention will be described in detail below with reference to the accompanying drawings. The same reference numbers in the figures indicate functionally identical or similar elements. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

Embodiment 1 is shown in Figure 1. The liquid leakage alarm device provided by the present invention includes an induction tube 1 , a water flow sensor 2 and an alarm device 3 . The induction tube 1 is composed of an induction tube housing 6 and an induction tube built-in tube 7 . The induction tube housing 6 is made of plastic material, which has better compression resistance and toughness when the temperature is lower than 150°C, and can be melted and damaged when the temperature is higher than 150°C. The built-in tube 7 of the induction tube has three or more sections, is made of steel pipe, and the tube wall has holes distributed, and the end of the induction tube 5 is closed. The water flow sensor 2 is a liquid flow sensor of the LWGY type, which is connected in series between the water pipe 4 and the induction pipe 1, and can send a wireless signal when the liquid flows. Alarm 3 is an alarm of the LEPU-2000U model, which sends out a sound signal when receiving a signal.

When in use, the induction tube 1 is arranged in a physical fixing method at the places where high-temperature liquid leaks such as the brick joints of the glass furnace body and the furnace bottom gap must pass, and the tap water pipe 4 of the water flow sensor 2 is connected with the tap water, and the other end It is connected with the induction tube 1, and the alarm is placed where the staff can perceive it.

When the high-temperature liquid does not leak, because the plastic of the sensing tube shell 6 is not damaged, the water in the sensing tube 1 does not flow, the water flow sensor 2 will not send a signal, and the alarm 3 will not send an alarm signal.

When the high-temperature liquid leaks, the high-temperature liquid flows through the position where the induction tube 1 is located. Since the temperature of the liquid is higher than 150°C, the plastic wall of the induction tube shell 6 will melt, and the water will start to flow out, forming a water vapor mist, and at the same time causing the water in the induction tube to Flow, after the water flow sensor 2 senses that the water is flowing, it sends out a wireless signal, and after the alarm 3 receives the wireless signal, it sends out a sound alarm. The built-in tube 7 of the induction tube has good mechanical strength under the cooling of water, and will not cause the position deviation of the induction tube 1 . After hearing the alarm, the staff can quickly locate the location of the glass leak according to the water vapor mist and take measures. This device also has a self-sealing function. After the outer layer of the induction tube is broken, the water flowing out can cool the leak, which can achieve the effect of blocking and delaying the outflow of high-temperature liquid.

Embodiment 2 is shown in Fig. 2 and Fig. 3 . The high-temperature liquid leakage alarm device provided by the present invention includes an induction tube 11 , a pressure sensor 12 and an alarm 13 . The induction tube 11 includes a rectangular induction tube housing 10 and a built-in tube 14 . The built-in tube 14 in the induction tube 11 is made of stainless steel and is in the shape of a cuboid with holes on its large surface and sides. The induction tube shell 10 is made of low temperature resistant material, which has better compression resistance and toughness when the temperature is lower than 150°C, and can be melted and damaged when the temperature is higher than 150°C. The pressure sensor 12 is a gas pressure sensing device of the PMC131-A11F1D12 model, which is connected in series between the air pressure bag 8 and the induction tube 11 through the connecting pipe 9, and can send a wireless signal when the gas pressure decreases. Alarm device 13 is the alarm device of LEPU-2000U model, sends sound signal when receiving signal.

Before use, the induction tube 11 is arranged at a place where high-temperature liquid leakage is likely to occur, and is fixed by a physical method. When the high-temperature liquid leaks, the high-temperature liquid flows through the position where the induction tube 11 is located. Since the temperature of the liquid is higher than 150°C, the plastic wall of the induction tube housing 10 will be melted, and the gas will start to spray out. After the pressure sensor 12 senses the change in the air pressure , send a wireless signal, and the alarm 13 sends a sound alarm after receiving the wireless signal. After the staff hears the alarm sound, they can take measures to the location of the glass leakage.

This device also has a certain self-sealing function. After the induction tube shell 10 is broken, the gas can cool the leaking place, which can prevent and delay the high-temperature liquid from flowing out. At the same time, since the gas is non-conductive, this device can be used in places with dense circuits or where waterproofing is required. In addition, the induction tube 11 is for surface monitoring, and induction tubes of different shapes can be manufactured according to actual conditions, so as to achieve the purpose of comprehensively monitoring the leakage of high-temperature liquid.
