Description

Technical Field

[0001] This utility model relates to the field of biphenyl vaporization furnace technology, and in particular to an automatic steam temperature monitoring device for a biphenyl vaporization furnace. Background Technology

[0002] The biphenyl vaporization furnace (hereinafter referred to as biphenyl furnace) is a high-efficiency and energy-saving heating equipment widely used in industries such as chemical fiber, chemical, textile, printing and dyeing, plastics, and rubber. Its main purpose is to convert liquid biphenyl into gaseous state through heating, so that the heat of gaseous biphenyl can be used to heat other substances or processes. This type of heating furnace is particularly important in chemical fiber production, as it can provide a stable high-temperature environment to ensure the quality of chemical fiber products and production efficiency.

[0003] In the prior art, a temperature-controlled biphenyl vaporization furnace, as described in patent publication number CN214119989U, includes a vaporization chamber with an internal liquid level detector, liquid temperature detector, and heating rod. A raw material inlet connected to the external biphenyl raw liquid is also located on one side wall. The heating rod and liquid temperature detector are positioned below the liquid level detector. This device ensures that the temperature of the biphenyl vapor entering subsequent processes remains within a certain range, thus achieving a constant raw material temperature. However, this device does not have multiple monitoring instruments installed on the outer wall of the biphenyl vaporization furnace, making it impossible to effectively monitor the steam temperature inside the furnace. This inaccurate monitoring can easily lead to improper temperature control within the furnace, affecting subsequent conveying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic steam temperature monitoring device for a biphenyl vaporization furnace, in order to solve the problem that such devices do not have multiple monitoring instruments installed on the outer wall of the biphenyl vaporization furnace, thus failing to monitor the steam temperature inside the furnace effectively. This inaccurate monitoring can lead to improper temperature control inside the furnace, thereby affecting the subsequent transmission effect.

[0005] To achieve the above objectives, an automatic steam temperature monitoring device for a biphenyl vaporization furnace is provided, comprising a base plate, two bottom frames fixed to the top of the base plate, an outer frame fixed to the inner side of the left bottom frame, a biphenyl vaporization furnace body disposed inside the outer frame, a furnace top fixed to the top of the biphenyl vaporization furnace body, a discharge chute penetrating the left side of the furnace top, a discharge hood fixed to the inner side of the discharge chute, a heating box fixed to the inner side of the right bottom frame, the heating box being connected to the biphenyl vaporization furnace body via a transmission pipe, a first temperature sensor and a second temperature sensor respectively fixed to the outer side of the biphenyl vaporization furnace body and the furnace top, both of which are electrically connected to an external power supply.

[0006] According to the automatic steam temperature monitoring device for a biphenyl vaporization furnace, the inner side of the outer frame is fixed with support frames at both the front and rear ends along the transverse direction, and multiple support frames are fixed with electric heating tubes on their inner sides. The outer side of the outer frame is fixed with controllers at both the front and rear ends, and each electric heating tube is electrically connected to the corresponding controller.

[0007] According to the automatic steam temperature monitoring device for a biphenyl vaporization furnace, the outer frame is embedded with snap-fit ​​blocks around its top four sides, the main body of the biphenyl vaporization furnace is snapped into the inner side of multiple snap-fit ​​blocks, and pressure blocks are fixed around the outer perimeter of the outer frame. The multiple pressure blocks are connected to the corresponding snap-fit ​​blocks by reinforcing bolt threads.

[0008] According to the automatic steam temperature monitoring device for a biphenyl vaporization furnace, a buffer sponge block is fixed to the bottom inner side of the outer frame, and the main body of the biphenyl vaporization furnace is fixed to the top side of the buffer sponge block.

[0009] According to the automatic steam temperature monitoring device for a biphenyl vaporization furnace, the inner sides of the multiple snap-fit ​​blocks are all arc-shaped.

[0010] According to the aforementioned automatic steam temperature monitoring device for a biphenyl vaporization furnace, a control valve is installed at the top of the transmission pipe.

[0012] According to the automatic steam temperature monitoring device for a biphenyl vaporization furnace, the discharge hood is integrally convex.

[0013] The above-mentioned solution has the following advantages: Liquid biphenyl is fed into the inner side of the biphenyl vaporization furnace body through a discharge hood. Then, the electric heating tube, under the control of the corresponding controller, is energized and heats up the inner part of the outer frame, promoting the rapid vaporization of liquid biphenyl. The heating temperature is controlled in a closed loop through feedback from the controller and temperature sensors. The vaporized biphenyl vapor is transported to the heating box through a transmission pipe. During the process, the steam flow is regulated by a control valve to ensure stable transmission. The sealing area formed by the baffle plate and the snap-fit ​​block prevents hot gas from escaping and maintains stable pressure inside the furnace. Furthermore, the first and second temperature sensors installed on the outer side of the biphenyl vaporization furnace body and the furnace top collect temperature data from different locations in real time. Multi-sensor fusion technology is used to compare and analyze the temperature signals from the two locations, eliminating single-point measurement errors and improving monitoring accuracy. When the temperature is abnormal, the system can automatically adjust the heating power or trigger an alarm, thereby enhancing its practicality.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model discloses an automatic steam temperature monitoring device for a biphenyl vaporization furnace, comprising a base plate 1, two base frames 2 fixed to the top of the base plate 1, an outer frame 3 fixed to the inner side of the left base frame 2, a biphenyl vaporization furnace body 4 disposed inside the outer frame 3, a furnace top 5 fixed to the top of the biphenyl vaporization furnace body 4, a discharge chute 6 penetrating through the left side of the top surface of the furnace top 5, a discharge hood 7 fixed inside the discharge chute 6, a heating box 8 fixed to the inner side of the right base frame 2, and a transmission pipe 9 connecting the heating box 8 to the biphenyl vaporization furnace body 4. A first temperature sensor 10 and a second temperature sensor 11 are respectively fixed to the outer sides of the biphenyl vaporization furnace body 4 and the furnace top 5. Both the first temperature sensor 10 and the second temperature sensor 11 are connected to the outer side of the furnace top 5. In existing technologies, such devices do not have multiple monitoring instruments installed on the outer wall of the biphenyl vaporization furnace, making it impossible to effectively monitor the steam temperature inside the furnace. This inaccurate monitoring can easily lead to improper temperature control within the furnace, affecting subsequent transmission efficiency. To address this issue, a first temperature sensor 10 and a second temperature sensor 11 can be fixed to the outer sides of the main body 4 and the furnace top 5 of the biphenyl vaporization furnace, respectively. This enables multi-sensor fusion monitoring, sensing the real-time temperature of the outer sides of the main body 4 and the furnace top 5 and outputting usable signals. This eliminates single-point measurement errors and improves the effectiveness of automatic steam temperature monitoring.

[0024] The outer frame 3 has support frames 12 fixed at both the front and rear ends of its inner side along the horizontal direction. Multiple support frames 12 have electric heating tubes 13 fixed inside. The outer frame 3 has controllers 14 fixed at both the front and rear ends of its outer side. Each electric heating tube 13 is electrically connected to the corresponding controller 14. By setting support frames 12 and electric heating tubes 13 at both the front and rear ends of the inner side of the outer frame 3, the temperature inside the outer frame 3 is increased by converting the electrical energy of the electric heating tubes 13 into heat energy, thereby enhancing the efficiency of converting liquid biphenyl into gas.

[0025] The outer frame 3 has snap-fit ​​blocks 15 embedded around its top four sides. The biphenyl vaporizer body 4 is snapped into the inner side of multiple snap-fit ​​blocks 15. The outer frame 3 is also fixed with pressure blocks 16 around its outer four sides. Multiple pressure blocks 16 are threadedly connected to the corresponding snap-fit ​​blocks 15 using reinforcing bolts 17. By setting snap-fit ​​blocks 15, pressure blocks 16 and reinforcing bolts 17, the outer side of the biphenyl vaporizer body 4 is snapped and fixed. The inner bottom of the outer frame 3 is fixed with a buffer sponge block 18. The biphenyl vaporizer body 4 is fixed to the top side of the buffer sponge block 18, which provides buffer support for the bottom of the biphenyl vaporizer body 4.

[0026] Multiple snap-fit ​​blocks 15 are all arc-shaped on the inside to avoid wear on the exterior of the biphenyl vaporizer body 4. A control valve 19 is provided at the top of the transmission pipe 9 to facilitate the control of the steam inside the biphenyl vaporizer body 4 and to transmit it to the heating box 8 through the transmission pipe 9.

[0027] The outer frame 3 has baffles 20 fixed on both the front and rear sides of the top. The two baffles 20 and multiple snap-fit ​​blocks 15 form a sealed area to prevent hot air from overflowing. The discharge hood 7 is convex in shape to increase the discharge area of ​​liquid biphenyl.

[0028] Working principle: First, liquid biphenyl is fed into the inner side of the biphenyl vaporization furnace body 4 through the discharge hood 7. Then, the electric heating tube 13 is energized and heated under the control of the corresponding controller 14, which heats the inside of the outer frame 3, causing the liquid biphenyl to vaporize rapidly. The heating temperature is controlled in a closed loop through feedback from the controller 14 and the temperature sensor. The vaporized biphenyl vapor is transported to the heating box 8 through the transmission pipe 9. During the process, the steam flow is regulated by the control valve 19 to ensure stable transmission. The sealing area formed by the baffle plate 20 and the snap-fit ​​block 15 prevents hot gas from escaping and maintains stable pressure inside the furnace. The first temperature sensor 10 and the second temperature sensor 11 installed on the outside of the biphenyl vaporization furnace body 4 and the furnace top 5 collect temperature data at different locations in real time. Multi-sensor fusion technology is used to compare and analyze the temperature signals from the two locations, eliminating single-point measurement errors and improving monitoring accuracy. When the temperature is abnormal, the system can automatically adjust the heating power or trigger an alarm to enhance its practicality.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
