Description

Technical Field

[0001] This application relates to the technical field of pyrolysis heating furnaces, and in particular to a heat preservation structure for pyrolysis heating furnaces. Background Technology

[0002] In asphalt thermal pyrolysis tests, asphalt is usually poured into a flask and then placed in the heating tank of a heating furnace. The control console controls the heating tubes in the heating tank to heat the flask. With the development of technology, heating furnaces have been widely used in the field of asphalt thermal pyrolysis tests, which has greatly promoted the progress of related research and production.

[0003] However, most heating furnaces are currently designed to be open, with the flasks exposed outside the heating bath, resulting in uneven heating, which seriously affects the accuracy of the test results. Furthermore, the installation and fixing of the flasks is cumbersome and inconvenient, greatly reducing work efficiency and increasing the labor intensity of the operators. Summary of the Invention

[0004] To improve heating uniformity and facilitate flask installation and operation, this application provides a heat preservation structure for a pyrolysis heating furnace.

[0005] This application provides a heat insulation structure for a pyrolysis heating furnace, which adopts the following technical solution:

[0006] A heat insulation structure for a pyrolysis heating furnace, comprising:

[0007] Console;

[0008] The heating furnace has a heating groove on its top wall for placing flasks, and heating tubes are installed inside the heating groove;

[0009] A clamping frame is used to hold and secure the neck of a flask.

[0010] A sealing cap fits into the heating chamber. The top wall of the sealing cap has a through slot for the neck of the flask to pass through. A sealing sleeve is provided at the through slot to fill the gap between the flask and the through slot, so that the sealing cap and the heating furnace form a sealed heating chamber in the heating chamber.

[0011] By adopting the above technical solution, the flask is placed in the heating groove on the top wall of the heating furnace, providing a stable placement space for the subsequent heating process. Then, the neck of the flask is clamped and fixed using a clamping frame to ensure the stability of the flask during the heating process and reduce the possibility of shaking affecting the heating effect. Then, the sealing cap is placed on the heating groove, and the sealing sleeve fills the gap between the flask and the slot, thereby forming a sealed heating chamber. This effectively reduces heat loss, improves heating efficiency, and allows the heating gas to flow in the heating chamber, improving heating uniformity. The heating of the flask is more stable and efficient, ultimately ensuring the smooth progress of the pyrolysis heating process and improving the reliability and accuracy of the overall test or production.

[0012] Optionally, the clamping frame includes a base, a support rod, a horizontal bar, and a clamping clip. The support rod is connected to the top of the base, the horizontal bar is installed on the top of the support rod, and the clamping clip is connected to the horizontal bar. The clamping clip is located on the top of the heating bath and is used to clamp and fix the neck of the flask.

[0013] By adopting the above technical solution, the base provides support and a stable foundation for the entire clamping frame. The support rod is connected to the top of the base and extends upward to a certain height, so that the clamping part is in a suitable position. The horizontal bar is installed on the top of the support rod to determine the lateral position of the clamping clip. The clamping clip is connected to the horizontal bar and located at the top of the heating tank, which can accurately clamp and fix the neck of the flask. All components work together, which can easily and quickly fix the neck of the flask in actual operation, reducing the possibility of cumbersome traditional installation and fixing methods, and greatly improving the convenience and efficiency of operation.

[0014] Optionally, the clamping clamp includes a first clamping plate, a second clamping plate, and a torsion spring. One end of the first clamping plate is connected to a horizontal bar, one side of the second clamping plate is connected to the torsion spring, and the end of the torsion spring away from the first clamping plate is connected to the second clamping plate. The first clamping plate is rotatably connected to a hinge rod, and the hinge rod is rotatably connected to the second clamping plate. The outer wall of the first clamping plate is in contact with the inner wall of the second clamping plate, and the ends of the first and second clamping plates away from the torsion spring form a clamping end.

[0015] By adopting the above technical solution, when it is necessary to clamp the neck of the flask, the elastic action of the torsion spring will cause the first clamp and the second clamp to tend to move closer to each other. The first clamp and the second clamp can rotate around the hinge rod to adjust their positions so as to better fit the neck of the flask. This allows the operator to easily open and close the clamping ends of the first clamp and the second clamp, thereby achieving rapid fixing and disassembly of the neck of the flask. The operation is simple, saves time and manpower, and improves the efficiency of flask installation and fixing.

[0016] Optionally, the support rod is slidably connected to a lifting block, and the lifting block is threadedly connected to a lifting locking component. One end of the lifting locking component is pressed against the support rod, and the horizontal bar is installed on the lifting block.

[0017] By adopting the above technical solution, the support rod can be height-adjusted through the lifting block and lifting locking component, so that the horizontal rod installed on the lifting block can drive the clamping clamp to achieve height adjustment, thereby better adapting to the clamping and fixing needs of flasks of different heights, and making the clamping operation of the clamping frame on the neck of the flask more flexible and convenient.

[0018] Optionally, the lifting block is threadedly connected to a horizontal locking element, which abuts against the horizontal bar.

[0019] By adopting the above technical solution, the horizontal locking component presses against the horizontal bar, making the lifting block relatively fixed to the horizontal bar. When it is necessary to remove the sealing cap and flask from the heating tank, the clamp can be easily moved to move the clamp away from the top of the heating tank, making it easier for the sealing cap and flask to detach from the heating tank and facilitating subsequent operations.

[0020] Optionally, the heating tube is spiral-shaped, with the diameter of the top spiral being larger than that of the bottom spiral.

[0021] By adopting the above technical solution, the spiral heating tube with a larger diameter at the top than at the bottom increases the contact area between the heating tube and the flask, allowing for better heating around the flask. The larger diameter at the top heats more of the upper part of the flask, while the smaller diameter at the bottom adapts to the shape of the flask's bottom. This ensures appropriate heating coverage for all parts of the flask from top to bottom, guaranteeing uniform heating and reducing experimental errors.

[0022] Optionally, the sealing cover is spherical, and a limiting ring is connected to the bottom wall of the sealing cover. When the sealing cover is closed on the heating furnace, the inner wall of the limiting ring abuts against the outer wall of the heating furnace.

[0023] By adopting the above technical solution, the spherical sealing cover and the limiting ring cooperate to accurately position the cover, so that the sealing cover is more stably covered on the heating furnace, and the limiting ring abuts against the outer wall of the heating furnace, further preventing heat from being lost from the connection between the sealing cover and the heating furnace.

[0024] Optionally, a sealing ring is connected to the bottom wall of the sealing cover. When the sealing cover is closed on the heating furnace, the side of the sealing ring away from the sealing cover is in contact with the heating furnace.

[0025] By adopting the above technical solution, when the sealing cover is closed on the heating furnace, the sealing ring is attached to the heating furnace, which further enhances the sealing performance between the sealing cover and the heating furnace, significantly reduces heat loss, and greatly improves heating efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Place the flask in the heating groove on the top wall of the heating furnace to provide a stable placement space for the subsequent heating process. Then, use a clamping frame to clamp and fix the neck of the flask to ensure the stability of the flask during the heating process and reduce the possibility of shaking affecting the heating effect. Then, put the sealing cap on the heating groove, so that the sealing sleeve fills the gap between the flask and the slot, thereby forming a sealed heating chamber, effectively reducing heat loss, improving heating efficiency, allowing the heating gas to flow in the heating chamber, improving heating uniformity, and making the heating of the flask more stable and efficient. Ultimately, this ensures the smooth progress of the pyrolysis heating process and improves the reliability and accuracy of the overall test or production.

[0028] 2. The base provides support and a stable foundation for the entire clamping frame. The support rod is connected to the top of the base and extends upward to a certain height, so that the clamping part is in a suitable position. The horizontal bar is installed on the top of the support rod to determine the lateral position of the clamping clip. The clamping clip is connected to the horizontal bar and located at the top of the heating tank, which can accurately clamp and fix the neck of the flask. All components work together to easily and quickly fix the neck of the flask in actual operation, reducing the possibility of cumbersome traditional installation and fixing methods, and greatly improving the convenience and efficiency of operation.

[0029] 3. The spiral heating tube, with a larger diameter at the top than at the bottom, increases the contact area between the heating tube and the flask, allowing for better heating around the flask. The larger diameter at the top heats more of the upper part of the flask, while the smaller diameter at the bottom accommodates the shape of the flask's bottom. This ensures adequate heating coverage for all parts of the flask from top to bottom, guaranteeing uniform heating and reducing experimental errors. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0036] This application discloses a heat preservation structure for a pyrolysis heating furnace.

[0037] Reference Figure 1 and Figure 2 A heat preservation structure for a pyrolysis heating furnace includes a control console 1, a heating furnace 2, a clamping frame 3, and a sealing cover 4. The control console 1 is electrically connected to the heating furnace 2 and can control the operation of the heating tube 22 of the heating furnace 2. The clamping frame 3 is located near the heating furnace 2 to clamp and fix the neck of the flask 5. The top wall of the heating furnace 2 has a heating groove 21 for placing the flask 5. The heating tube 22 is installed in the heating groove 21. The sealing cover 4 is closed on the heating groove 21. The top wall of the sealing cover 4 has a through slot 41 for the neck of the flask 5 to pass through. A sealing sleeve 42 is provided at the through slot 41. The sealing sleeve 42 is used to fill the gap between the flask 5 and the through slot 41, so that the sealing cover 4 and the heating furnace 2 form a sealed heating cavity at the heating groove 21. The sealing sleeve 42 can be made of silicone or rubber, both of which have good elasticity and sealing performance.

[0038] When heating flask 5, place flask 5 in heating chamber 21, align the through slot 41 with the top of flask 5, and put the sealing cap 4 on the neck of flask 5 until the sealing cap 4 is closed with heating chamber 21 and the sealing sleeve 42 is tightly fitted on the neck of flask 5, so that the round bottom of flask 5 is completely in the heating chamber, effectively reducing heat loss, reducing the possibility of uneven heating due to heat loss, improving heating uniformity, and facilitating the installation and fixation of flask 5.

[0039] Reference Figure 1 and Figure 3The clamping frame 3 includes a base 31, a support rod 32, a horizontal rod 33, and a clamping clamp 34. The base 31 supports the entire clamping frame 3 and is generally made of a heavy metal material, such as cast iron, to ensure its stability and reduce the possibility of shaking during clamping. The support rod 32 is vertically and fixedly connected to the top wall of the base 31. The heating furnace 2 is fixed to the top wall of the base 31. The support rod 32 is slidably connected to a lifting block 35. The lifting block 35 has a sliding hole that matches the support rod 32, allowing the lifting block 35 to slide up and down along the support rod 32. The lifting block 35 is threadedly connected to a lifting locking member 36. One end is pressed against the outer wall of the support rod 32. In this example, the lifting locking part 36 is bolted. The horizontal rod 33 is installed on the top of the support rod 32. Specifically, the horizontal rod 33 is slidably connected to the lifting block 35. The sliding direction of the horizontal rod 33 is horizontal and perpendicular to the lifting direction of the lifting block 35. The lifting block 35 is threadedly connected to the horizontal locking part 37. In this example, the horizontal locking part 37 is bolted. The horizontal locking part 37 is pressed against the horizontal rod 33. The clamping clip 34 is fixedly connected to one end of the horizontal rod 33. The clamping clip 34 is located on the top of the heating tank 21. The clamping clip 34 is used to clamp and fix the neck of the flask 5.

[0040] When the position of the clamping clip 34 needs to be adjusted, the lifting locking member 36 is turned to separate it from the support rod 32, thereby adjusting the height of the lifting block 35. After moving the lifting block 35 to the appropriate height, the lifting locking member 36 is tightened so that one end of the lifting locking member 36 is firmly against the support rod 32, thus fixing the position of the lifting block 35. This changes the height of the horizontal rod 33 to accommodate flasks 5 of different heights. By turning the horizontal locking member 37 to separate it from the horizontal rod 33, the horizontal rod 33 can be moved, allowing it to slide horizontally. After moving the horizontal rod 33 to the appropriate height, the horizontal locking member 37 is tightened so that one end of the horizontal locking member 37 is firmly against the outer wall of the horizontal rod 33, thus fixing the horizontal position of the horizontal rod 33. This changes the height and horizontal position of the horizontal rod 33 to accommodate flasks 5 of different heights, further allowing for precise adjustment of the position of the clamping clip 34.

[0041] Specifically, the clamping clamp 34 includes a first clamping piece 341, a second clamping piece 342, and a torsion spring 343. One end of the first clamping piece 341 is fixedly connected to the horizontal rod 33. One side of the second clamping piece 342 is fixedly connected to the torsion spring 343. The end of the torsion spring 343 away from the first clamping piece 341 is fixedly connected to the second clamping piece 342. The first clamping piece 341 is rotatably connected to a hinge rod 344. The hinge rod 344 is rotatably connected to the second clamping piece 342. The outer wall of the first clamping piece 341 is in contact with the inner wall of the second clamping piece 342, thereby limiting the position of the first clamping piece 341, the second clamping piece 342, and the torsion spring 343 to achieve a clamping effect. The ends of the first clamping piece 341 and the second clamping piece 342 away from the torsion spring 343 form a clamping end, and the clamping side of the clamping end is arc-shaped.

[0042] When it is necessary to clamp the neck of flask 5, press the first clamp 341 and the second clamp 342 to overcome the elastic force of the torsion spring 343, put the neck into the clamping end, and then release. The elastic force of the torsion spring 343 will cause the first clamp 341 and the second clamp 342 to clamp the neck tightly. The torsion spring 343 plays the role of providing clamping force here. Of course, a spring structure can also be used to replace the torsion spring 343 to achieve a similar clamping function.

[0043] Reference Figure 2 The heating tube 22 is spiral in shape, and the diameter of the top spiral of the heating tube 22 is larger than that of the bottom spiral. When the flask 5 is placed in the heating tank 21, the spiral shell of the heating tube 22 is distributed along the bottom of the flask 5. The larger diameter top spiral can provide more heat, thus ensuring that the flask 5 is heated more evenly.

[0044] The sealing cover 4 is spherical, a shape that facilitates heat accumulation and improves heating efficiency. A limiting ring 43 is fixedly connected to the bottom wall of the sealing cover 4. When the sealing cover 4 is closed on the heating furnace 2, the inner wall of the limiting ring 43 abuts against the outer wall of the heating furnace 2, serving a positioning and auxiliary sealing function. A sealing ring 44 is also fixedly connected to the bottom wall of the sealing cover 4. When the sealing cover 4 is closed on the heating furnace 2, the side of the sealing ring 44 furthest from the sealing cover 4 adheres to the top wall of the heating furnace 2, further enhancing the sealing effect.

[0045] The implementation principle of the insulation structure for a pyrolysis heating furnace in this embodiment is as follows: Asphalt is poured into a flask 5, which is then placed stably into the heating tank 21 of the heating furnace 2. Based on the specific height of the flask 5, the lifting locking piece 36 on the lifting block 35 is loosened, and the lifting block 35 is moved up and down. After adjusting to a suitable height, the lifting locking piece 36 is tightened to fix the position of the lifting block 35. The sealing cap 4 is then placed on the heating tank 21, allowing the neck of the flask 5 to pass through the through slot 41 on the sealing cap 4. At this time, the sealing sleeve 42 fills the gap between the flask 5 and the through slot 41. Simultaneously, the inner wall of the limiting ring 43 abuts against the outer wall of the heating furnace 2, and the sealing ring 44 adheres to the heating furnace 2. The first clamping piece 341 of the clamping clip 34 is then pressed down. The second clamp 342 overcomes the elastic force of the torsion spring 343. Then, according to the position of the flask 5, the horizontal locking member 37 is adjusted, and the horizontal position of the horizontal rod 33 is finely adjusted so that the clamping clamp 34 is in a suitable position to accurately clamp the neck of the flask 5. The neck of the flask 5 is placed into the clamping end, the first clamp 341 and the second clamp 342 are released, and the neck is clamped by the elastic force of the torsion spring 343. The heating tube 22 is started through the control console 1 to heat the flask 5. The sealing cap 4, the sealing sleeve 42, the limiting ring 43 and the sealing ring 44 together construct a sealed heating chamber, thereby forming a sealed heating chamber, effectively reducing heat loss, improving heating efficiency, and allowing the heating gas to flow in the heating chamber, improving heating uniformity.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
