Description

Technical Field

[0001] The invention specifically relates to a radioactive liquid vitreous temperature measuring device and a glass solidification device. Background Art

[0002] In recent years, the glass solidification process has been used to treat radioactive liquids. The glass solidification process first pre-treats the radioactive liquid through calcination to convert it into an oxide, and then mixes it with a glass substrate in a certain proportion in a calcination furnace, melts it, and pours it. After annealing, the radioactive nuclides are fixed in the glass network to form a stable glass solid body.

[0003] Temperature is one of the important parameters in the glass solidification process. However, due to the radioactivity, high temperature and electrical conductivity of the liquid glass in the calcining furnace, traditional temperature measuring devices are often corroded and have a short service life. In addition, due to the non-compact structure, it is difficult to replace the device over a long distance. Furthermore, it is difficult to accurately determine the depth when extending into the furnace, resulting in inaccurate positioning, which affects the temperature measurement of the furnace and ultimately affects the operation of glass solidification. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a radioactive liquid vitreous temperature measuring device in view of the above-mentioned deficiencies in the prior art, which has a compact structure, reasonable arrangement, convenient long-distance replacement, long service life, accurate positioning, and ensures temperature measurement reliability. The present invention also provides a glass solidification device.

[0005] The present invention provides a radioactive liquid vitreous body temperature measuring device, comprising a temperature measuring tube, a thermocouple assembly and a first flange. The thermocouple assembly is used to measure the temperature. The thermocouple assembly is accommodated inside the temperature measuring tube and penetrates into the shell of the device to be measured to separate the thermocouple assembly from the internal area of ​​the shell of the device to be measured, and the part of the temperature measuring tube located outside the shell of the device to be measured is detachably connected to the shell of the device to be measured through the first flange.

[0006] Furthermore, the thermocouple assembly includes a temperature measuring part, a pipe well and a buckle. The pipe well passes through the first flange to connect the inside and outside of the temperature measuring tube. The temperature measuring part is detachably connected to the end of the temperature measuring tube protruding from the pipe well through the buckle. The detection end of the temperature measuring part protrudes into the temperature measuring tube along the pipe well. The temperature measuring part can leave the pipe well together with the detection end after the buckle is loosened.

[0007] Furthermore, the temperature measuring part includes a thermocouple wire, a shell and a thermocouple tube. The thermocouple tube is sleeved and connected in the pipe well. The thermocouple wire serves as the detection end of the temperature measuring part. One end of the thermocouple wire is inserted into the thermocouple tube, and the other end is fixedly connected to the shell. The shell is detachably connected to the pipe well by a snap.

[0008] Furthermore, the buckle includes a connecting block, an elastic member and a lever, the connecting block is connected to the pipe well, the connecting block and the lever are hinged to each other, presenting a structure that interlocks with each other around the hinge, and the connecting block and the lever are provided with concave areas on the engaging surfaces, and after interlocking, the concave areas are connected to form a through hole with a diameter smaller than the diameter of the outer shell cross section, and the elastic member is connected between the connecting block and the lever, so that the lever remains engaged with the connecting block under the action of the elastic member.

[0009] Furthermore, the thermocouple assembly and the temperature measuring tube are arranged in a vertical direction, and the thermocouple assembly is provided with multiple groups, and each group of thermocouple assemblies is located in the temperature measuring tube with a different length to obtain the temperature at different depth positions in the device to be measured.

[0010] Furthermore, the radioactive liquid vitreous body temperature measuring device also includes a second flange, which is connected to the end of the temperature measuring tube located outside the shell of the temperature measuring device to be measured. The thermocouple assembly is connected to the second flange and is relatively fixed to the temperature measuring tube through the second flange to ensure mutual insulation between the thermocouple assembly and the temperature measuring tube.

[0011] Furthermore, the radioactive liquid vitreous body temperature measuring device also includes an insulating block. The first flange is arranged on the outer wall of the temperature measuring tube, connecting the temperature measuring tube and the shell of the temperature measuring equipment to be measured. The insulating block is arranged between the first flange and the second flange to ensure that the second flange and the first flange are insulated from each other.

[0012] Furthermore, the first flange is provided with fasteners and guide pins, and the first flange determines the connection position with the housing of the temperature-measured device through the guide pins, and is fixedly connected to the housing of the temperature-measured device through the fasteners.

[0013] The present invention also provides a glass solidification device, including a calcining furnace and the above-mentioned radioactive liquid glass temperature measuring device, wherein the calcining furnace is used to accommodate and calcine the radioactive liquid glass; the radioactive liquid glass temperature measuring device is connected to the calcining furnace and penetrates into the calcining furnace to measure the internal temperature of the calcining furnace.

[0014] The radioactive liquid vitreous temperature measuring device of the present invention has a temperature measuring tube and a housing of a device to be measured that are detachably connected by a flange, which facilitates direct remote operation and replacement of the entire radioactive liquid vitreous temperature measuring device. The temperature measuring tube is connected to the housing of the device, and the temperature measuring tube itself can also serve as a positioning basis for the thermocouple assembly. The accurate insertion position for temperature measurement can be obtained by combining the installation dimensions between the thermocouple assembly and the temperature measuring tube with the dimensions of the thermocouple assembly itself.

[0015] More importantly, a temperature measuring tube is used to separate the thermocouple assembly used for temperature measurement from the internal area of ​​the housing of the device to be measured, so that the thermocouple assembly can be inside the furnace while avoiding direct contact with the liquid in the furnace. Compared with the current conventional temperature measuring device that directly extends into the furnace for temperature measurement, it can effectively avoid corrosion of the thermocouple assembly caused by the liquid in the furnace, extend its service life, and still be able to fully collect temperature data.

[0016] And precisely because the influence of the slurry is reduced by the isolation method, the possibility of the conductive slurry being connected to the temperature measuring thermocouple can be avoided, thereby further reducing the adverse effect on the temperature measurement accuracy and greatly improving the temperature measurement reliability of the thermocouple assembly.

[0025] Example 1

[0026] like Figure 1 As shown, the radioactive liquid glass temperature measuring device of this embodiment includes a temperature measuring tube 1, a thermocouple assembly 2 and a first flange 3. The thermocouple assembly 2 is used to measure the temperature. The thermocouple assembly 2 is accommodated inside the temperature measuring tube 1 and penetrates into the housing of the device to be measured to separate the thermocouple assembly 2 from the internal area of ​​the housing of the device to be measured, and the portion of the temperature measuring tube 1 located outside the housing of the device to be measured is detachably connected to the housing of the device to be measured through the first flange 3. The device of this embodiment belongs to the technical field of radioactive high-temperature liquid glass temperature measurement, and specifically relates to a device for measuring the temperature of radioactive high-temperature liquid glass, which is used to measure the temperature of glass in a calcining furnace, a melting furnace, and a temperature measuring device.

[0027] The temperature measuring tube 1 of the device is detachably connected to the housing of the device to be measured by flange, which is convenient for direct remote operation and replacement of the entire radioactive liquid vitreous temperature measuring device. The temperature measuring tube 1 is used to connect the device housing, and the temperature measuring tube 1 itself can also serve as the positioning basis of the thermocouple assembly 2. The accurate insertion position for temperature measurement can be obtained by combining the installation dimensions between the thermocouple assembly 2 and the temperature measuring tube 1 with the dimensions of the thermocouple assembly 2 itself. When there are multiple thermocouple assemblies 2, they can all be accommodated in the same temperature measuring tube 1, and the temperature measuring tube 1 is used to connect to the device housing, which not only avoids their respective dispersion and has good integrity, but also can use the same position as the positioning reference, making it easier to determine the temperature measurement position, with a smaller relative error, and avoiding the problem that each temperature measuring component needs to be determined separately due to the curved structure of the device housing.

[0028] More importantly, the temperature measuring tube 1 is used to separate the thermocouple assembly 2 used for temperature measurement from the internal area of ​​the housing of the device to be measured, so that the thermocouple assembly 2 can be inside the furnace and avoid direct contact with the liquid in the furnace. Compared with the current conventional temperature measuring device directly extending into the furnace for temperature measurement, it can effectively avoid the corrosion of the thermocouple assembly 2 caused by the liquid in the furnace, extend the service life, and still be able to fully collect temperature data.

[0029] And precisely because the influence of the slurry is reduced by the isolation method, the possibility of the conductive slurry being connected to the temperature measuring thermocouple can be avoided, thereby further reducing the adverse effect on the temperature measurement accuracy and greatly improving the temperature measurement reliability of the thermocouple assembly 2.

[0030] In this embodiment, the thermocouple assembly 2 includes a temperature measuring part 21, a tube well 22 and a buckle 23. The tube well 22 passes through the first flange 3 to connect the inside and outside of the temperature measuring tube 1. The temperature measuring part 21 is detachably connected to the end of the tube well 22 protruding from the temperature measuring tube 1 through the buckle 23. The detection end of the temperature measuring part 21 protrudes into the temperature measuring tube 1 along the tube well 22. After the buckle 23 is loosened, the temperature measuring part 21 can leave the tube well 22 together with the detection end.

[0031] By providing a snap-on 23 (also called a snap-on connector) structure, not only can the entire device be disassembled and installed through the first flange 3, but the temperature measuring part 21 of a separate thermocouple assembly 2 can also be disassembled and installed, which is convenient for separate replacement and reduces the cost of replacement and maintenance.

[0032] In this embodiment, Figure 3 As shown, the temperature measuring part 21 includes a thermocouple wire 211, a shell 212 and a thermocouple tube 213. The thermocouple tube 213 is sleeved and connected in the pipe well 22. The thermocouple wire 211 serves as the detection end of the temperature measuring part 21. One end of the thermocouple wire 211 is inserted into the thermocouple tube 213, and the other end is fixedly connected to the shell 212. The shell 212 is detachably connected to the pipe well 22 through a buckle 23. When the thermocouple wire 211 needs to be replaced, the buckle 23 is opened, and the thermocouple wire 211 can be driven out of the thermocouple tube 213 by removing the shell 212.

[0033] In this embodiment, the buckle 23 includes a connection block 231, an elastic member 232 and a lever 233. The connection block 231 is connected to the pipe well 22. The connection block 231 and the lever 233 are hinged to each other, and are in a structure that is mutually engaged around the hinge. The buckling surfaces of the connection block 231 and the lever 233 are both provided with a concave area. After being engaged, the concave area is connected to form a through hole with a diameter smaller than the cross-sectional diameter of the shell 212, thereby clamping the shell 212 and making it difficult for it to move relative to the pipe well 22. The elastic member 232 is connected between the connection block 231 and the lever 233, so that the lever 233 remains engaged with the connection block 231 under the action of the elastic member 232.

[0034] In this embodiment, the elastic member 232 is a leaf spring. Figure 2 As shown, the lever 233 of the buckle 23 rotates around the small circular hole on the lever 233 to achieve the buckling and opening with the connecting block 231. An arc hole (arc direction is concentric with the small circular hole) can also be provided on the lever 233, and a clamping head can be provided on the connecting block 231, and the clamping head is embedded in the arc hole. When the lever 233 rotates, the arc hole and the clamping head can achieve a limiting effect.

[0035] In this embodiment, the thermocouple assembly 2 and the temperature measuring tube 1 are arranged in the vertical direction. There are multiple groups of thermocouple assemblies 2. The lengths of the thermocouple assemblies 2 in each group in the temperature measuring tube 1 are different to obtain the temperatures at different depths in the temperature measuring device.

[0036] In this embodiment, the device further includes a second flange 4, which is connected to the end of the temperature measuring tube 1 outside the housing of the device to be measured, and the thermocouple assembly 2 is connected to the second flange 4. The second flange 4 is used to achieve relative fixation with the temperature measuring tube 1 to ensure mutual insulation between the thermocouple assembly 2 and the temperature measuring tube 1, so that even if the feed liquid is connected to the temperature measuring tube 1, it will not affect the internal thermocouple assembly 2. Specifically, the temperature measuring tube 1 is a cylindrical structure with an open top and a closed bottom. The second flange 4 is sealed and connected to the top opening of the temperature measuring tube 1. A connection hole can be set on the second flange 4 for connecting the thermocouple assembly 2.

[0037] In this embodiment, the device also includes an insulating block 5. The first flange 3 is arranged on the outer wall of the temperature measuring tube 1 to connect the temperature measuring tube 1 and the shell of the temperature measuring device to be measured. The insulating block 5 is padded between the first flange 3 and the second flange 4 to ensure that the second flange 4 and the first flange 3 are insulated from each other, thereby ensuring that the shell of the temperature measuring device to be measured and the thermocouple assembly 2 are insulated from each other to prevent the charged liquid from being conductive to the thermocouple assembly 2.

[0038] In this embodiment, fasteners and guide pins 31 are provided on the first flange 3. The first flange 3 determines the connection position with the housing of the temperature measurement device through the guide pins 31, and is fixedly connected to the housing of the temperature measurement device through fasteners, further facilitating remote operation using automated equipment or a manipulator.

[0039] This embodiment provides a device for measuring the temperature of radioactive high-temperature liquid glass, and its main devices include: a buckle 23 connector, which is arranged on the top of the thermocouple assembly 2 for remote installation; an insulating block 5, which is arranged on the upper part of the first flange 3, and is used to separate the thermocouple assembly 2 from the furnace shell to prevent the thermocouple assembly 2 from conducting electricity and affecting the measurement accuracy; the thermocouple assembly 2, which is arranged in the temperature measuring tube 1, is used to measure the temperature of the liquid glass; and the temperature measuring tube 1 and the second flange 4. The above-mentioned component materials of this device (except the insulating block 5, the insulating block 5 can be made of insulating materials that meet the requirements) can be selected from corrosion-resistant alloys, which have excellent high-temperature corrosion resistance, and can further isolate the thermocouple assembly 2 from the furnace shell, and have a simple structure, which can meet the requirements of remote disassembly and assembly in the hot chamber.

[0040] Specifically, the bottom of the temperature measuring tube 1 penetrates into the equipment into the glass melting pool. A plurality of tube wells 22 may be arranged inside the temperature measuring tube 1, and a plurality of thermocouples may be integrated into one. The depths of the tube wells are different, and are used to measure the liquid levels at different depths of the air cavity inside the furnace and the melting pool.

[0041] Multiple thermocouple assemblies 2 can be provided to measure the temperature of the air cavity at different heights; the thermocouple assembly 2 is not in contact with the first flange 3 and the insulating block 5, but in contact with the second flange 4 to ensure that the thermocouple assembly 2 is non-conductive, and the diameter of the pipe well 22 outside the thermocouple assembly 2 is DN6. The temperature measuring part 21 can be installed in the pipe well 22 through a remote power mechanical device, and there are multiple thermocouple wires 211, and each thermocouple wire 211 has the same length and the same interface, and is interchangeable in design. In this embodiment, the thermocouple assembly 2 is integrated into one device, and the temperature at different positions in the furnace can be measured, and each thermocouple assembly 2 can be set to an interchangeable structure, which can well reduce the number of thermocouple spare parts.

[0042] The guide pin 31 can be used for guiding when the temperature measuring device is installed at a distance. The fastener of the first flange 3 can be a connecting bolt, which is used to connect the first flange 3 and the furnace equipment. The connecting bolt is provided with an anti-drop device, which can be operated at a distance. A lifting ring can also be provided on the first flange 3. The lifting ring cooperates with a special lifting device to realize the remote disassembly and assembly of the temperature measuring device.

[0043] The snap-on connector includes a connecting block 231, a leaf spring and a lever 233; the lever 233 and the connecting block 231 can also be connected to other devices for remote installation. When removed, the lever 233 and the connecting block 231 will not be completely tightly closed, and the through hole in the middle concave area facilitates the thermocouple wire 211 to extend into the thermocouple tube 213.

[0044] The insulating block 5 is arranged between the first flange 3 and the second flange 4 to avoid contact with the temperature measuring thermocouple, and can isolate the conductive shell of the furnace and the temperature measuring tube to ensure that the furnace shell is not electrified.

[0045] The thermocouple assembly 2 contains a thermocouple wire 211 inside, which needs to be inserted into the thermocouple tube 213. The thermocouple housing 212 cooperates with the connecting block 231 in the buckle 23 for remote disassembly and assembly. When the temperature measuring device is remotely disassembled and assembled, the lever 233 can be remotely moved through the power mechanical device, and the lever 233 is in a state of clamping the housing 212, and then changes to a relaxed state. Through the elasticity of the leaf spring, the buckle 23 is opened, and the thermocouple housing 212 is pulled out. The thermocouple wire 211 and the thermocouple housing 212 are pulled out from the temperature measuring tube 1 through the power mechanical device, so that the thermocouple can be replaced remotely.

[0046] When the temperature measuring device is disassembled and assembled remotely as a whole, the first flange 3 and the connecting bolts are removed by a power mechanical device, the temperature measuring device can be disconnected from the furnace equipment, and the temperature measuring device can be lifted out by a special lifting device to complete the remote disassembly and assembly of the temperature measuring device.

[0049] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
