Description

Technical Field

[0001] The utility model relates to the field of glass kilns, and more specifically, to a temperature measuring device for 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 in 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 melt of the glass kiln during temperature measurement and pulled out after the temperature measurement is completed, this method also requires the temperature sensor to be in the kiln for a long time. If it needs to be completely pulled out, it will cause ventilation at the temperature measuring hole, resulting in heat waste.

[0004] Therefore, a new type of temperature measuring 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 measuring device is always in a high temperature environment, which affects its service life.

[0006] According to one aspect of the utility model, a glass kiln temperature measuring device is provided, including a kiln body and a temperature sensor, wherein a sampling hole is arranged at the bottom of the kiln body, a temperature measuring cavity is arranged below the sampling hole, a sampler is connected to the sampling hole, and the sampler is used to sample the glass melt in the sampling hole into the temperature measuring cavity, wherein the temperature sensor is arranged in the temperature measuring cavity.

[0007] Through this solution, the sampler samples the molten glass in the kiln body through the sampling hole and transfers it to the temperature measuring chamber for temperature measurement. There is no need to directly extend the temperature sensor into the kiln for temperature measurement, which can reduce the baking time in the kiln. In addition, the sampler can isolate the heat radiation from the kiln to the temperature sensor, which helps to increase the service life of the temperature sensor.

[0008] Preferably, the sampler comprises a sampling roller and a driving mechanism, the sampling roller is rotatably connected to the sampling hole, the diameter of the sampling roller is consistent with the sampling hole, a sampling groove is provided on the sampling roller, and the driving mechanism drives the sampling roller to rotate.

[0009] Through this solution, the rotation of the sampling roller can drive the molten glass that falls into the sampling groove through the sampling hole to the temperature measuring cavity below. The molten glass falls into the temperature measuring cavity under the action of gravity to complete the temperature measurement; due to the viscosity of the molten glass, it will not flow into the temperature measuring cavity through the gap.

[0010] Preferably, the driving mechanism comprises a driving motor and a driving shaft, and the driving shaft passes through the sampling roller and is rotatably connected to the kiln body.

[0011] Through this solution, the drive shaft is made of tungsten steel, and the drive shaft passes through the sampling roller to improve the strength of the sampling roller, so as to improve the reliability of working under high temperature.

[0012] Preferably, the middle parts of both ends of the sampling roller extend outward to form a protection part, and the protection part is arranged concentrically with the driving shaft.

[0013] Through this solution, the protective part can protect the drive shaft and reduce the impact of high temperature on the life of the drive shaft.

[0014] Preferably, the area below the sampling hole is enlarged to form a mounting cavity, the sampling roller is mounted in the mounting cavity, and the length and width of the mounting cavity are both larger than the sampling hole.

[0015] Through this solution, the sampling roller can cover the sampling hole, reduce the gap between the sampling hole and the sampling roller, maintain a certain sealing performance of the kiln body, and avoid the loss of molten glass and heat.

[0016] Preferably, the temperature measuring cavity is a groove at the bottom of the kiln body, and a blocking mechanism is provided below the kiln body for blocking or opening the temperature measuring cavity.

[0017] Through this solution, it is convenient to discharge the waste glass melt after the temperature measurement is completed and carry out the next temperature measurement.

[0018] Preferably, the blocking mechanism comprises a blocking plate and a driving cylinder, a piston rod of the driving cylinder is hinged to the blocking plate, and one side of the blocking plate is hinged to the bottom of the kiln body.

[0019] Through this solution, the driving cylinder is located at the bottom of the sealing plate and will not be affected by the burning of the flowing molten glass, thereby increasing the service life.

[0020] One of the technical effects of the utility model is that, by using the glass kiln temperature measuring device of the present application, there is no need for the temperature sensor to be directly inserted into the kiln body for long-term measurement. Only intermittent sampling and temperature measurement are required, which helps to greatly increase the service life of the temperature sensor. Moreover, due to the isolation of the sampler, unnecessary loss of temperature in the kiln will not occur.

[0021] Other features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] like Figures 1 to 5As shown, a glass kiln temperature measuring device in an embodiment of the present application includes a kiln body 100 and a temperature sensor 104. A sampling hole 101 is provided at the bottom of the kiln body 100, a temperature measuring cavity 102 is provided below the sampling hole 101, a sampler 200 is connected to the sampling hole 101, and the sampler 200 is used to sample the glass melt in the sampling hole 101 into the temperature measuring cavity 102, and a temperature sensor 104 is provided in the temperature measuring cavity 102.

[0034] Through the scheme of this embodiment, the sampler 200 samples the molten glass in the kiln body 100 through the sampling hole 101, and transfers it to the temperature measuring chamber 102 for temperature measurement. There is no need for the temperature sensor 104 to be directly inserted into the kiln for temperature measurement, which can reduce the baking time in the kiln. In addition, the sampler 200 can isolate the heat radiation from the kiln to the temperature sensor 104, which helps to increase the service life of the temperature sensor 104.

[0035] In one embodiment of the present application, the sampler 200 includes a sampling roller 210 and a driving mechanism. The sampling roller 210 is rotatably connected to the sampling hole 101. The diameter of the sampling roller 210 is consistent with the sampling hole 101. The sampling roller 210 is provided with a sampling groove 211. The driving mechanism drives the sampling roller 210 to rotate. The rotation of the sampling roller 210 can drive the molten glass that falls into the sampling groove 211 through the sampling hole 101 to the temperature measurement cavity 102 below. The molten glass falls into the temperature measurement cavity 102 under the action of gravity to complete the temperature measurement; due to the viscosity of the molten glass, it will not flow into the temperature measurement cavity 102 through the gap.

[0036] The sampling roller 210 in this embodiment is made of high temperature resistant materials such as ceramics, corundum, clay, etc., can withstand a temperature of about 1500°C, and has a certain strength to ensure its stable operation.

[0037] In one embodiment of the present application, the driving mechanism includes a driving motor 221 and a driving shaft 222. The driving shaft 222 penetrates the sampling roller 210 and is rotatably connected to the kiln body 100. The driving shaft 222 is made of tungsten steel, and the driving shaft 222 penetrates the sampling roller 210 to improve the strength of the sampling roller 210, so as to improve the reliability of working at high temperature.

[0038] In one embodiment of the present application, the middle parts of both ends of the sampling roller 210 extend outward to form a protective portion 212, and the protective portion 212 is arranged concentrically with the drive shaft 222. The protective portion 212 can protect the drive shaft 222 and reduce the impact of high temperature on the life of the drive shaft 222.

[0039] In one embodiment of the present application, the lower part of the sampling hole 101 is expanded to form a mounting cavity 103, and the sampling roller 210 is mounted in the mounting cavity 103. The length and width of the mounting cavity 103 are both larger than the sampling hole 101. The sampling roller 210 can cover the sampling hole 101, reduce the gap between the sampling hole 101 and the sampling roller 210, maintain a certain sealing of the kiln body 100, and avoid the loss of molten glass and the loss of heat.

[0040] The cross section of the mounting cavity 103 is circular, and the sampling roller 210 is matched with a cylindrical structure. Both ends of the mounting cavity 103 are provided with receiving grooves for inserting the protective part 212. The size of the receiving groove is consistent with the mounting part, further reducing the infiltration of the glass melt and the impact on the driving shaft 222.

[0041] In one embodiment of the present application, the temperature measurement cavity 102 is a groove at the bottom of the kiln body 100, and a blocking mechanism 300 is provided below the kiln body 100 for blocking or opening the temperature measurement cavity 102. It is convenient to discharge the waste gas molten glass after the temperature measurement is completed and perform the next temperature measurement.

[0042] In one embodiment of the present application, the blocking mechanism 300 includes a blocking plate 310 and a driving cylinder 320. The piston rod of the driving cylinder 320 is hinged to the blocking plate 310, and one side of the blocking plate 310 is hinged to the bottom of the kiln body 100. The driving cylinder 320 is located at the bottom of the blocking plate 310 and will not be affected by the outflowing molten glass, thereby increasing its service life.

[0043] The sealing plate 310 is provided with a plurality of grooves for guiding the flow direction of the molten glass, so as to facilitate the recovery of the discharged molten glass and prevent the lateral outflow from affecting the driving cylinder 320 .

[0044] One technical effect of this embodiment is that, by using the glass kiln temperature measuring device of the present application, there is no need for the temperature sensor 104 to be directly inserted into the kiln body 100 for long-term measurement. Only intermittent sampling and temperature measurement are required, which helps to greatly increase the service life of the temperature sensor 104. Moreover, due to the isolation of the sampler 200, unnecessary loss of temperature in the kiln will not occur.
