Description

Technical Field

[0001] The present application relates to the technical field of detection instruments and equipment, and in particular to a detection device. Background Art

[0002] In the current steelmaking production process, the high-temperature molten steel coming out of the steelmaking furnace will be transported or stored for a short period of time in different ladles. At this time, the molten steel needs to be adjusted, purified, and tested. During the detection of the molten steel, the temperature of the molten steel is very high, reaching more than 1000 degrees. Ordinary detection devices cannot adapt to the high temperature environment and cannot perform liquid level measurement. In addition, the molten steel body has a red flame, and infrared rays cannot be used for long-distance temperature measurement. The measured value is inaccurate, which affects the subsequent molten steel processing. In addition, when the detection component is working, its processor has a higher ambient temperature requirement at work, and its processor temperature requirement at work is slightly higher than its scanning end. Continuous use of constant temperature control will cause errors in the measurement data and is not conducive to extending the life of the device. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0032] Reference Figure 1-Figure 3 , the present application embodiment provides a detection device, including:

[0033] The box body 1 has a detection port 2 formed at the bottom thereof;

[0034] A radar component 3 is disposed in the box 1, and a detection end of the radar component 3 is disposed toward the detection port 2;

[0035] a mica plate 4, disposed below the radar assembly 3, the mica plate 4 separating the radar assembly 3 from the object to be detected and allowing the radar signal of the radar assembly 3 to pass through; and

[0036] The cooling component includes an air inlet connector 5 disposed on the box body 1 , and the cooling component introduces cooling gas into the box body 1 through the air inlet connector 5 to cool the radar component 3 .

[0037] The box body 1 provides a location for the radar assembly 3 to be installed and placed. The box body 1 is provided with a detection port 2, and the radar assembly 3 located inside the box body 1 can detect the part to be detected through the detection port 2. When the part to be detected is a high-temperature material such as high-temperature molten iron, the mica board 4 located below the radar assembly 3 has a heat insulation effect to prevent the radar assembly 3 from being damaged by high-temperature thermal radiation, and the mica board 4 will not block the radar signal. The radar signal of the radar assembly 3 can pass through the mica board 4 to detect the part to be detected. Therefore, the detection device provided in the present application can detect high-temperature materials and can ensure the service life of the radar assembly 3. In addition, cooling gas is introduced into the box body 1 through the cooling assembly, and the cooling gas can cool down the radar assembly 3, further ensuring the reliability of the radar assembly 3.

[0038] The existing general liquid level radar cannot measure high-temperature molten iron, mainly because the liquid level radar needs to be arranged directly above the liquid. The thermal radiation of the high-temperature molten iron will damage the liquid level radar, and the smoke raised by the molten iron will interfere with the signal of the liquid level radar. The antenna 32 transmitting system inherited by the lower part of the liquid level radar is sealed in the plastic sphere and cannot withstand high temperatures. When the thermal radiation temperature is too high, the plastic sphere will melt, causing the liquid level radar to fail. In order to avoid the melting of the plastic sphere, a metal partition can be placed in front of the radar antenna 32, but the metal partition will also block the radar signal while insulating. In addition, in order for the liquid level radar to work properly, the temperature of the working environment of its internal electronic components is not easy to be too high. Therefore, the present application uses a mica plate 4 to block the antenna 32 of the liquid level radar and the molten iron. The mica plate 4 will not block the radar signal while isolating the temperature, and the reliable use of the radar component 3 can be guaranteed.

[0039] The mica board 4 can be made by bonding mica paper with organic silica gel water and then heating and pressing. For example, the mica board 4 can be an HP-8 hard gold mica board 4. The mica board 4 can withstand a high temperature of about 850°C under continuous use conditions and a high temperature of about 1050°C under intermittent use conditions. This structure ensures that only the mica board 4 blocks the antenna 32 of the radar assembly 3 and the molten iron level of the to-be-detected part. The mica board 4 can effectively ensure that the radar wave can easily penetrate, thereby achieving the purpose of accurate measurement.

[0040] Reference Figure 1-Figure 3 In some embodiments, a support plate 6 is disposed in the box 1, the support plate 6 is located above the mica board 4 and the radar assembly 3 is disposed on the support plate 6, the main body 31 of the radar assembly 3 is located above the support plate 6, and the antenna 32 of the radar assembly 3 passes through the support plate 6 and is disposed toward the mica board 4. The support plate 6 supports and fixes the radar assembly 3, and provides an installation position for the radar assembly 3.

[0041] Specifically, the radar assembly 3 includes a main body 31 and an antenna 32 connected to each other. The main body 31 is located above the support plate 6 , and the antenna 32 passes through the support plate 6 and is located on a side of the support plate 6 facing the mica board 4 .

[0042] The support plate 6 is provided with an air guide hole 7, through which the air inside the box 1 is connected, ensuring that the cooling gas can be passed into the radar component 3 no matter where the air inlet connector 5 is arranged, thereby cooling the radar component 3.

[0043] Optionally, the radar component 3 is arranged in the middle position of the support plate 6 to ensure that the radar component 3 can be located directly above the molten iron, thereby facilitating the determination of the position of the radar component 3 inside the box 1 and ensuring the accuracy of the data detected by the radar component 3.

[0044] Of course, the cooling assembly also includes an air outlet joint 8 and a purge joint 9 provided on the box 1, an air duct 10 is connected between the air outlet joint 8 and the purge joint 9, the air outlet joint 8 is connected to the radar assembly 3, and the purge end of the purge joint 9 faces the bottom of the mica board 4; the cooling gas after passing through the radar assembly 3 can be discharged from the box 1 through the air outlet joint 8 to ensure the circulation of the cooling gas inside the box 1. In addition, the air outlet joint 8 and the purge joint 9 are connected through the air duct 10, and the gas flowing out from the inside of the box 1 will be blown toward the bottom of the mica board 4 through the purge joint 9, thereby purging the bottom of the mica board 4, purging the high-temperature and high-speed dust particles brought up by the thermal convection of the molten iron, preventing the particles from accumulating under the mica board 4, agglomerating and slagging, thereby affecting the penetration of the radar wave, and the purged gas can also isolate the hot air to prevent the temperature of the mica board 4 from rising due to thermal radiation.

[0045] Reference Figure 1-Figure 3 The mica board 4 includes a first end and a second end that are relatively arranged, the first end and the second end are respectively connected to the box body 1, and the first end is located above the second end; by tilting the mica board 4, the purge effect of the gas purge under the mica board 4 can be further improved.

[0046] For the convenience of description, the interior of the box 1 is divided into an upper chamber and a lower chamber through the mica board 4, wherein the space area above the mica board 4 is the upper chamber, and the space area below the mica board 4 is the lower chamber; the purge joint 9 is arranged opposite to the first end of the mica board 4, and the gas blown out of the purge joint 9 toward the mica board 4 will move along the inclined direction of the mica board 4 under the inclined setting of the mica board 4, thereby improving the purging effect of smoke and dust. In addition, through the inclined setting of the mica board 4, the gas will form a purge gas path in the lower chamber of the protective device: after the gas enters the lower chamber, it forms a downward cyclone under the action of the mica board 4, which purges the high-temperature and high-speed dust particles brought up by the thermal convection of the molten iron.

[0047] At the same time, when the mica plate 4 is tilted, the cooling gas enters the upper cavity and forms a cooling gas path. After the gas enters the upper cavity, it forms an upward cyclone under the action of the mica plate 4, cools the body of the radar assembly 3 and the antenna 32 of the radar assembly 3, and finally flows out from the drainage interface and enters the air duct 10. The cooling gas can also increase the pressure of the upper cavity, forming a back pressure, so that the surrounding dust cannot enter the upper cavity, isolating the dust, thereby protecting the radar assembly 3.

[0048] Optionally, the air inlet connector 5 is connected to the space between the mica board 4 and the support plate 6, and the air outlet connector 8 is connected to the space above the support plate 6. The cooling gas in the upper cavity flows out through the air guide holes 7 on the support plate 6, thereby guiding the flow of the cooling gas and improving the cooling effect.

[0049] Optionally, the cooling gas may be compressed air or nitrogen. In the present application, nitrogen is used as the cooling gas.

[0050] Reference Figure 1-Figure 4 The bottom of the box 1 is provided with a mounting seat 11, and the mounting seat 11 is provided with a connector 14 for assembly; the mounting seat 11 is assembled and connected to any position to be detected by setting the connector 14, so as to realize the stable assembly of the box 1. Of course, the internal skeleton of the box 1 can be connected by angle steel welding, and the outer shell is a steel shell. The use of a hard shell can prevent external impact and protect the internal components of the internal radar. Adjacent steel shells can be tightened and fixed by screws. Similarly, the connector 14 can also be a screw or a bolt, which is convenient for installation and debugging.

[0051] Handles 13 may also be provided on two symmetrical sides of the box body 1 , and the handles 13 are used to facilitate carrying the box body 1 .

[0052] The inner side of the box 1 is provided with a heat insulating member 12, which provides heat insulation to the external environment and the inside of the box 1, thereby preventing damage to the radar assembly 3. Optionally, the heat insulating member 12 is a heat insulating board, which may be an asbestos rubber board, and can provide good sealing and heat insulating effects.

[0053] The outer peripheral side of the box body 1 is provided with a high temperature resistant component to ensure the reliability of the box body 1. Optionally, the high temperature resistant component is an acrylic polyurethane heat-resistant and anti-corrosion topcoat coated on the outer side of the box body 1.

[0054] Reference Figure 1-Figure 4 In summary, the detection device provided in the embodiment of the present application solves the problem of being unable to accurately measure the liquid level of high-temperature molten iron. The device solves the cooling and smoke interference of the radar component 3 through a cooling air path and a purge air path, and prevents the mica plate 4 from slagging and causing the radar wave to be unable to penetrate.
