Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinning heating technology, specifically to a biphenyl furnace heater. Background Technology
[0002] In the spinning process, a biphenyl furnace is often used for heating. After the biphenyl is heated to a specified temperature, it turns into a gaseous state and flows from the biphenyl furnace to the spinning box, releasing heat to keep the spinning box warm. The heated biphenyl then flows back to the biphenyl furnace to be heated again. This cycle continues, keeping the temperature of the spinning box at the set value.
[0003] Authorization announcement number CN212870743U discloses a biphenyl furnace, including a furnace body, a tray disposed within the furnace body, and heating tubes disposed within the trays. The furnace body has an exhaust port at its top. Multiple trays are spaced apart along the axial direction of the furnace body, with gaps forming between the trays and the side walls of the furnace body. A feed pipe is located on the upper part of the side walls of the furnace body, with one end extending into the furnace body and corresponding to the topmost tray. Each heating tube corresponds to one tray, with both ends extending out of the furnace body. This application has the effect of increasing the steam generation rate.
[0004] In practical applications, the coils of biphenyl furnaces are often bonded to the surface of the tray. However, this brings a series of potential problems during transportation, use, or installation. Due to the bond between the coil and the heat sink, the coil is prone to shaking when subjected to bumps or impacts. This shaking may cause friction between the coil and the tray, resulting in the coating on the coil peeling off, affecting the normal use of the coil and its heat conduction effect. Utility Model Content
[0005] The purpose of this invention is to provide a biphenyl furnace heater to solve the technical problem that the coil and tray are prone to collision in the prior art.
[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0007] A biphenyl furnace heater includes a cap and a furnace body. The cap has a steam outlet at its top, and the cap and furnace body form a cavity. The heater also includes:
[0008] The heating plate and heating tube are provided. Several heating plates are arranged vertically on the inner wall of the heating furnace body. A gap is left between the heating plate and the side wall of the heating furnace body. Each heating plate is provided with a liquid level control structure. Several heating tubes are provided, and each is located on the top of the corresponding heating plate. Each heating plate and heating tube are fixed by a pressure plate. The bottom of the pressure plate has a fixing hole that matches the heating tube. The fixing hole on the pressure plate is engaged with the top of the heating tube. A locking component is provided between the pressure plate and the heating plate. An injection pipe is provided on the upper part of the side wall of the cap. One end of the injection pipe extends into the cap and corresponds to the top of the heating plate.
[0009] As a further embodiment of this utility model: a connecting platform is provided on the side of the connection between the cap and the heating furnace body, and the two connecting platforms are detachably connected by bolts or buckles.
[0010] As a further embodiment of this utility model: an umbrella-shaped gas collecting hood is provided on the inner side of the cap, the bottom of the gas collecting hood is connected to the side wall of the cap, and the top of the gas collecting hood is connected to the steam outlet.
[0011] As a further aspect of this utility model, the size of the heating plate gradually increases from the top of the heating furnace body downwards.
[0012] As a further embodiment of this utility model: the engaging assembly includes insert plates, and several insert plates are provided. Each insert plate is fixedly connected to the upper surface of the heating plate. Several through holes aligned with the insert plates are opened on the pressure plate. The insert plates are inserted into the corresponding through holes. A groove is opened horizontally through the insert plate. An elastic plate inclined to one side is provided inside the groove. The free end of the elastic plate abuts against the inner wall of the through hole. A locking block is provided on the top side of the insert plate away from the elastic plate. The locking block engages with the top side of the through hole.
[0013] As a further embodiment of this utility model, a lever is also provided on the top of the insert plate.
[0014] As a further embodiment of this utility model: a plurality of support frames corresponding to the heating plate are distributed on the inner side wall of the heating furnace body, and connecting screws are provided on the opposite side edges of the heating plate, the connecting screws passing through the side edges of the heating plate and threadedly connected to the support frames.

[0016] As a further embodiment of this utility model, the cap is provided with a lifting handle on both outer side walls.
[0017] As a further embodiment of this utility model: a second heating tube is also provided at the bottom of the heating furnace body, and both ends of the second heating tube extend to the outside of the heating furnace body.
[0018] The beneficial effects of this utility model are:
[0019] 1. In this utility model, the fixing hole at the bottom of the pressure plate abuts against the top of the heating tube, and then the locking assembly is used to fix the pressure plate so that the pressure plate contacts the heating tube and limits the heating tube, thereby preventing the heating tube from shaking and preventing the heating tube from rubbing against the upper surface of the heating plate.
[0020] 2. During the insertion process, the elastic plate deforms and is compressed inside the through hole. The elastic plate generates a reverse elastic force on the insertion plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figures 1-5 As shown, a biphenyl furnace heater includes a cap 1 and a furnace body 2. The cap 1 has a steam outlet 5 at its top. The cap 1 and the furnace body 2 form a cavity. Several support legs 10 are distributed at the bottom of the furnace body 2. Connecting platforms 3 are provided on the sides of the connection between the cap 1 and the furnace body 2. Two connecting platforms 3 are detachably connected by bolts or clips. Lifting handles 22 are provided on both outer walls of the cap 1. The cap 1 can be disassembled by removing the bolts or clips and holding the lifting handles 22 with both hands, facilitating later maintenance. The heater also includes heating plates 7 and heating tubes 8. Several heating plates 7 are provided and vertically fitted onto the inner wall of the furnace body 2. A gap is left between the heating plates 7 and the side walls of the furnace body 2. Each heating plate 7 is equipped with a liquid level control structure. Several heating tubes 8 are provided and are located on the top of their respective heating plates 7. Both heat pipe 8 and heating pipe 9 are used to transfer heat transfer oil and heat the biphenyl in the heating plate 7. Each heating plate 7 is fixed to the heating pipe 8 by a pressure plate 14. The bottom of the pressure plate 14 has a fixing hole 15 that matches the heating pipe 8. The fixing hole 15 on the pressure plate 14 engages with the top of the heating pipe 8. There are engaging components between the pressure plate 14 and the heating plate 7. The upper part of the side wall of the cap 1 is provided with an injection pipe 4. One end of the injection pipe 4 extends into the cap 1 and corresponds to the top of the heating plate 7. The two ends of the heating pipe 8 extend out of the heating furnace body 2. The fixing hole 15 at the bottom of the pressure plate 14 abuts against the top of the heating pipe 8. Then, the engaging components are used to fix the pressure plate 14 so that the pressure plate 14 contacts the heating pipe 8 and limits the heating pipe 8, thereby preventing the heating pipe 8 from shaking and preventing the heating pipe 8 from rubbing against the upper surface of the heating plate 7.
[0030] In some specific implementation plans, such as Figure 2 As shown, in order to prevent steam from accumulating above the cap 1, an umbrella-shaped gas collecting hood 6 is provided on the inner side of the cap 1. The bottom of the gas collecting hood 6 is connected to the side wall of the cap 1, and the top of the gas collecting hood 6 is connected to the steam outlet 5. The umbrella-shaped gas collecting hood 6 provides a guiding function for the steam.
[0031] In some specific implementation plans, such as Figure 2As shown, to ensure that each heating plate 7 is filled with a fixed amount of biphenyl, the size of the heating plate 7 gradually increases from the top of the furnace body 2 downwards. The liquid level control structure includes several equalization pipes 13, which are connected to the side wall of the heating plate 7. Biphenyl is injected into the top heating plate 7 from the injection pipe 4. When the biphenyl is injected to a level higher than the upper end of the equalization pipe 13, it can flow through the equalization pipe 13 into the lower heating plate 7 until all heating plates 7 are filled with biphenyl. The size of the heating plate 7 gradually increases to receive the biphenyl boiling in the previous heating plate 7. During the heating process, the heating plate 7 can divide the biphenyl into multiple portions, reducing the volume of heated biphenyl and enabling rapid steam generation, which speeds up the steam generation, saves resources, and reduces time.
[0032] In some specific embodiments, the engaging assembly includes several insert plates 17, each fixedly connected to the upper surface of the heating plate 7. A pressure plate 14 has several through holes 16 aligned with the insert plates 17, and the insert plates 17 are inserted into the corresponding through holes 16. A transversely extending groove 18 is formed on each insert plate 17, and an elastic plate 19 inclined to one side is disposed inside the groove 18. The free end of the elastic plate 19 abuts against the inner wall of the through hole 16. A locking block 20 is provided on the top side of the insert plate 17 away from the elastic plate 19, and the locking block 20 engages with the side of the through hole 16. The top of the insert plate 17 is also equipped with a lever 21. During use, the insert plate 17 is inserted into the corresponding through hole 16. During the insertion process, the elastic plate 19 deforms and is compressed inside the through hole 16. The elastic plate 19 generates a reverse elastic force on the insert plate 17. After the insertion is completed, the lever 20 is engaged with the top of the through hole 16, thereby fixing the pressure plate 14. Press the lever 21 towards the elastic plate 19 and pull the pressure plate 14 upward to disassemble the pressure plate 14, which facilitates the separation of the pressure plate 14 from the heating plate 7 and enables quick disassembly and assembly of the pressure plate 14.
[0033] In some specific implementations, in order to facilitate the replacement of the heating plate 7, several support frames 11 corresponding to the heating plate 7 are distributed on the inner side wall of the heating furnace body 2. Connecting screws 12 are provided on the opposite two side edges of the heating plate 7. The connecting screws 12 pass through the side edges of the heating plate 7 and are threadedly connected to the support frame 11. The heating plate 7 can be replaced by removing the connecting screws 12 on both sides.
[0034] In some specific implementations, in order to heat the biphenyl overflowing from the bottom of the heating furnace body 2, a second heating tube 9 is also provided at the bottom of the heating furnace body 2. Both ends of the second heating tube 9 extend to the outside of the heating furnace body 2. The biphenyl boiling in the heating plate 7 and falling into the bottom of the heating furnace body 2 is heated by the second heating tube 9, so that the biphenyl is fully utilized.
[0035] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
