Description

Technical Field

[0001] The utility model relates to the field of glass kilns, and more specifically, to a protective device for a temperature sensor of a glass kiln. Background Art

[0002] Glass kilns have high requirements for temperature and require frequent temperature measurements to ensure product quality.

[0003] Traditional temperature sensors are directly inserted into the kiln for measurement. Due to the high temperature inside the kiln, which usually reaches over 1500℃, the service life of the temperature sensor will be greatly reduced. If it is replaced after the furnace is shut down, the production efficiency will be greatly reduced. If a movable temperature measuring mechanism is used, that is, it is inserted into the glass kiln during temperature measurement and withdrawn after the temperature measurement is completed, it is necessary to set a temperature measuring hole on the side wall of the kiln, which greatly reduces the sealing of the kiln and affects its insulation effect.

[0004] Therefore, a new type of temperature sensor protection device for a glass furnace is needed to solve the above problems. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that the existing glass furnace temperature sensor has poor protection effect or affects the heat preservation effect of the furnace.

[0006] According to one aspect of the utility model, a glass kiln temperature sensor protection device is provided, including a protection tube, a temperature sensor is fixed to the bottom end of the protection tube, the top end of the protection tube extends into the furnace body through a temperature measuring hole, a driving cylinder is connected to the protection tube, the driving cylinder is used to drive the protection tube to extend into or pull out of the temperature measuring hole, the protection tube is connected to a micro fan, and the micro fan is used to draw air in the furnace body to the temperature sensor.

[0007] Through this solution, if temperature measurement is required, the protective tube is inserted into the temperature measuring hole, and the temperature is measured using the air extracted by the micro fan. This can reduce the high temperature compared to directly inserting the temperature into the furnace body. By correlating the temperature of the sucked out hot air with the temperature inside the furnace body, the current temperature inside the furnace body can be known. When temperature measurement is not required, the micro fan can be turned off and the protective tube can be pulled out of the furnace body. This can reduce the long-term impact of the temperature inside the furnace on the temperature sensor and increase its service life.

[0008] Preferably, a sealing block is provided at the top of the protection tube, the diameter of the sealing block is consistent with the temperature measuring hole, and an air suction hole is provided on one side of the top of the protection tube.

[0009] Through this solution, when there is no need to measure the temperature, the temperature measuring hole on the furnace body is sealed with a sealing block, which can not only avoid heat loss, but also avoid the high temperature directly burning the protective tube and the temperature sensor therein, thereby increasing the service life of the device.

[0010] Preferably, the temperature sensor is fixed to one side of the protection tube, and the diameter of the temperature sensor is smaller than the inner diameter of the protection tube.

[0011] Through this solution, when the micro fan is turned on, the high-temperature gas can smoothly pass through the temperature sensor so that it is wrapped by the high-temperature gas, thereby helping to measure the temperature more accurately.

[0012] Preferably, the arrangement direction of the micro-fans is consistent with the radial direction of the protection tube.

[0013] Through this solution, the Bernoulli principle is utilized to form negative pressure on one side of the micro fan, and hot air is sucked in after the cold air is discharged. Compared with the direct suction of the fan axial arrangement, more heat can be avoided from being discharged and the thermal insulation effect can be improved.

[0014] Preferably, the micro fans connected to adjacent protection tubes are connected through a connecting tube.

[0015] Through this solution, the air flow rate in the connecting pipe is increased, thereby improving the efficiency of air suction and reducing the detection time.

[0016] Preferably, a connecting portion is sleeved on the connecting pipe, and the driving cylinder is connected to the connecting portion.

[0017] Through this solution, the driving cylinder can drive multiple protective tubes to move at the same time, thereby improving synchronization and detection accuracy.

[0018] One of the technical effects of the utility model is that, by adopting the glass kiln temperature sensor protection device, the temperature measuring hole can be sealed to avoid heat loss while ensuring accurate temperature measurement. At the same time, it can protect the temperature sensor to avoid long-term exposure to high temperature environment affecting its service life.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] like Figures 1 to 4 As shown, a protective device for a glass kiln temperature sensor 110 in an embodiment of the present application comprises a protective tube 100, wherein the temperature sensor 110 is fixed to the bottom end of the protective tube 100, wherein the top end of the protective tube 100 extends into the furnace body through the temperature measuring hole 001, and a driving cylinder 310 is connected to the protective tube 100, wherein the driving cylinder 310 is used to drive the protective tube 100 to extend into or out of the temperature measuring hole 001, and a micro fan 200 is connected to the protective tube 100, wherein the micro fan 200 is used to draw air in the furnace body to the temperature sensor 110.

[0031] Through this embodiment, if temperature measurement is required, the protective tube 100 is inserted into the temperature measuring hole 001, and the temperature is measured using the air extracted by the micro fan 200. This can reduce the high temperature compared to directly inserting the temperature into the furnace body. By correlating the temperature of the sucked out hot air with the temperature inside the furnace body, the current temperature inside the furnace body can be known. When temperature measurement is not required, the micro fan 200 can be turned off and the protective tube 100 can be pulled out of the furnace body, which can reduce the long-term impact of the temperature inside the furnace on the temperature sensor 110 and increase its service life.

[0032] Before measuring the temperature, it is necessary to collect the temperature in each time period to develop a temperature change curve. Since the temperature inside the furnace will be different from the temperature of the hot air absorbed to the temperature sensor 110, a corresponding relationship table between the temperature inside the furnace and the temperature inside the tube is developed. After detecting the temperature inside the protective tube 100, the corresponding relationship table between the temperature inside the furnace and the temperature inside the tube is queried to obtain the corresponding temperature inside the furnace.

[0033] In one embodiment of the present application, a blocking block 120 is provided at the top of the protection tube 100, and the diameter of the blocking block 120 is consistent with the temperature measuring hole 001. An air intake hole 101 is provided on one side of the top of the protection tube 100. When it is not necessary to measure the temperature, the temperature measuring hole 001 on the furnace body is blocked by the blocking block 120, which can not only prevent the loss of heat, but also prevent the high temperature from directly burning the protection tube 100 and the temperature sensor 110 therein, thereby improving the service life of the device.

[0034] The protection tube 100 in this embodiment is made of, for example, tungsten steel, which has certain high temperature resistance and rigidity, or a high temperature resistant ceramic tube, which has higher high temperature resistance. The blocking block 120 is made of ceramic material or refractory bricks, which is not only high temperature resistant but also has a heat insulation effect to prevent a large amount of heat from entering the protection tube 100.

[0035] In one embodiment of the present application, the temperature sensor 110 is fixed to one side of the protection tube 100, and the diameter of the temperature sensor 110 is smaller than the inner diameter of the protection tube 100. When the micro-blower 200 is turned on, the high-temperature gas can smoothly pass through the temperature sensor 110 so that it is wrapped by the high-temperature gas, thereby facilitating more accurate temperature measurement.

[0036] The temperature sensor 110 is inserted into the central axis of the protection tube 100 , which can reserve enough space to discharge the cold air in the protection tube 100 and inhale the hot air.

[0037] In one embodiment of the present application, the arrangement direction of the micro fan 200 is consistent with the radial direction of the protection tube 100. By using the Bernoulli principle, negative pressure is formed on one side of the micro fan 200, and hot air is sucked in after cold air is discharged. Compared with the direct suction of the fan axial arrangement, more heat can be avoided from being discharged, thereby improving the heat preservation effect.

[0038] In one embodiment of the present application, the micro fans 200 connected to adjacent protection tubes 100 are connected through the connecting tube 320. The air flow rate in the connecting tube 320 is increased, thereby improving the efficiency of air suction and reducing the detection time.

[0039] In one embodiment of the present application, a connecting portion 330 is sleeved on the connecting pipe 320, and the driving cylinder 310 is connected to the connecting portion 330. The driving cylinder 310 can drive multiple protection pipes 100 to move at the same time, thereby improving synchronization and detection accuracy.

[0040] One technical effect of this embodiment is that by using the glass kiln temperature sensor protection device, the temperature measuring hole can be sealed to avoid heat loss while ensuring accurate temperature measurement. At the same time, it can protect the temperature sensor and prevent it from being exposed to high temperature environment for a long time, which affects its service life.

[0041] 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.
