Description

Technical Field

[0001] The utility model relates to the field of glass production equipment, and more specifically, to a temperature measuring device for a clarification channel of a glass kiln. Background Art

[0002] Glass kilns are used to melt raw materials such as glass slag and silicon dioxide to form molten glass. After meeting the required requirements, the molten glass is guided to the clarification channel for further clarification and cooling. The temperature requirement is high during the clarification process, and the temperature at the bottom of the molten glass needs to be frequently collected to ensure product quality.

[0003] Traditional temperature sensors (thermocouples) are directly inserted into the clarification channel for measurement. Since the temperature of the molten glass is relatively high, usually reaching over 1000°C, the service life of the temperature sensor will be greatly reduced. If the temperature sensor located at the top is inserted vertically to measure the temperature at the bottom of the clarification channel, the line will be directly damaged by the heat radiation.

[0004] Therefore, there is a need for a temperature measuring device for a glass furnace clarification channel that can solve the above problems. Utility Model Content

[0005] One purpose of the utility model is to solve the problem of low service life of the existing temperature measuring device for the clarification channel of a glass kiln.

[0006] According to one aspect of the utility model, a temperature measuring device for a clarification channel of a glass kiln is provided, comprising a clarification channel and a temperature sensor, wherein a through hole is arranged transversely through the bottom of the clarification channel, a protective roller is slidably connected in the through hole, the temperature sensor is embedded in the protective roller, and the protective roller is driven to move left and right by a driving mechanism; a temperature measuring hole is arranged at the bottom of the clarification channel, and the temperature sensor can be exposed from the temperature measuring hole when driven by the driving mechanism.

[0007] Through this solution, the protective roller is moved left and right to expose the temperature sensor to the temperature measuring hole for temperature measurement, and re-enter the through hole after the temperature measurement is completed, thereby avoiding long-term exposure to the glass melt, which helps to improve the service life.

[0008] Preferably, the protective roller comprises a core shaft and a protective sleeve, the protective sleeve is arranged on the core shaft, a plurality of mounting holes are arranged on the protective sleeve, and the temperature sensor is embedded in the mounting holes.

[0009] Through this solution, the core shaft can improve the strength of the protective roller and avoid breakage of the protective roller when moving after the installation hole is opened; the protective sleeve has a high temperature resistance and is easy to process, so that the temperature sensor is flush with the surface of the protective sleeve, which is convenient for movement in the through hole.

[0010] Preferably, the core shaft is a hollow structure, and the line of the temperature sensor is arranged through the core shaft to the outside of the clarification channel.

[0011] This solution can provide better protection for the lines.

[0012] Preferably, the driving mechanism comprises a driving frame and a driving cylinder, the driving frame is U-shaped and connected to both ends of the protective roller, and the driving cylinder drives the driving frame to move.

[0013] Through this solution, the protection roller and the driving frame form a frame structure, the thrust on the protection roller is balanced during movement, the deformation of the protection roller during movement is reduced, and the rupture caused by radial force is avoided.

[0014] Preferably, a slide rail is provided below the driving frame, and the driving frame is slidably connected to the slide rail.

[0015] Through this solution, the movement accuracy of the drive frame is further improved, ensuring that the force on the protective roller is located in the axial direction.

[0016] Preferably, a plurality of the protective rollers are connected side by side to the driving frame, and each protective roller is provided with at least two temperature sensors.

[0017] Through this solution, the movement of the driving frame can drive multiple temperature sensors to measure the temperature of the clarification channel at multiple positions at the same time, thereby reducing the number of driving mechanisms and reducing equipment costs.

[0018] Preferably, the temperature sensors on different protection rollers are arranged in a staggered manner.

[0019] Through this solution, the back and forth movement of the driving cylinder can drive different sensors to alternately pass through the temperature measuring holes to measure the temperature, thereby preventing a single temperature sensor from being subjected to high temperature for a long time while ensuring real-time monitoring.

[0020] One technical effect of the utility model is that the temperature measuring device of the clarification channel of the glass kiln can avoid the temperature sensor from contacting the glass melt for a long time, thereby improving the service life of the temperature sensor.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0029] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] like Figures 1 to 4 As shown, a temperature measuring device for a clarification channel of a glass kiln in an embodiment of the present application comprises a clarification channel 100 and a temperature sensor 300. A through hole 102 is arranged transversely through the bottom of the clarification channel 100. A protective roller 210 is slidably connected in the through hole 102. The protective roller 210 is embedded with the temperature sensor 300. The protective roller 210 is driven to move left and right by a driving mechanism. A temperature measuring hole 101 is arranged at the bottom of the clarification channel 100. The temperature sensor 300 can be exposed through the temperature measuring hole 101 under the drive of the driving mechanism.

[0033] Through the scheme of this embodiment, the protection roller 210 is moved left and right to expose the temperature sensor 300 to the temperature measuring hole 101 for temperature measurement, and re-enter the through hole 102 after the temperature measurement is completed, thereby avoiding long-term exposure to the glass melt, which helps to improve the service life.

[0034] Since the inner wall of the clarifying channel 100 is made of fireproof bricks or clay and has high high temperature resistance and heat insulation effect, the temperature of the outer wall of the clarifying channel 100 is only tens of degrees Celsius, which can avoid affecting the circuit of the temperature sensor 300.

[0035] The side wall of the temperature measuring hole 101 is sloped, which can reduce the resistance of the molten glass during its flow.

[0036] In one embodiment of the present application, the protection roller 210 includes a core shaft 212 and a protection sleeve 211. The protection sleeve 211 is set on the core shaft 212. The protection sleeve 211 is provided with a plurality of mounting holes 213, and the temperature sensor 300 is embedded in the mounting holes 213. The core shaft 212 can improve the strength of the protection roller 210 to avoid the protection roller 210 from breaking when moving after the mounting holes 213 are provided; the protection sleeve 211 plays a role of high temperature resistance and is easy to process, so that the temperature sensor 300 is flush with the surface of the protection sleeve 211, and is easy to move in the through hole 102.

[0037] The core shaft 212 is made of tungsten steel, has high rigidity, and can improve high temperature resistance; the protective sleeve 211 is made of corundum, ceramic or clay, etc., which not only has high temperature resistance, but also can improve surface smoothness and reduce friction with the through hole 102.

[0038] In one embodiment of the present application, the mandrel 212 is a hollow structure, and the circuit of the temperature sensor 300 is arranged outside the clarification channel 100 through the mandrel 212. It plays a better protection role for the circuit. One end of the mandrel 212 is open, and the extended circuit is connected to the control mechanism, which obtains the data collected by the temperature sensor 300 and performs calculations.

[0039] In one embodiment of the present application, the driving mechanism includes a driving frame 220 and a driving cylinder 230. The driving frame 220 is U-shaped and connected to both ends of the protection roller 210. The driving cylinder 230 drives the driving frame 220 to move. The protection roller 210 and the driving frame 220 form a frame structure, and the thrust on the protection roller 210 during the movement is balanced, reducing its deformation during the movement, and avoiding radial force and rupture.

[0040] In one embodiment of the present application, a slide rail 240 is disposed below the driving frame 220, the slide rail 240 is parallel to the protection roller 210, and the driving frame 220 is slidably connected to the slide rail 240. The moving accuracy of the driving frame 220 is further improved to ensure that the force on the protection roller 210 is located in the axial direction.

[0041] In one embodiment of the present application, a plurality of protective rollers 210 are connected in parallel to the driving frame 220, and at least two temperature sensors 300 are arranged on each protective roller 210. The movement of the driving frame 220 can drive the plurality of temperature sensors 300 to simultaneously measure the temperature of the clarification channel 100 at a plurality of positions, thereby reducing the number of driving mechanisms and reducing the equipment cost.

[0042] In one embodiment of the present application, the temperature sensors 300 on different protective rollers 210 are arranged alternately. The back and forth movement of the drive cylinder 230 can drive different sensors to alternately pass through the temperature measuring hole 101 for temperature measurement, thereby preventing a single temperature sensor 300 from being subjected to high temperature for a long time while ensuring real-time monitoring.

[0043] One technical effect of this embodiment is that the use of the temperature measuring device of the clarification channel of the glass kiln can prevent the temperature sensor from contacting the glass melt for a long time, thereby increasing the service life of the temperature sensor.

[0044] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
