Description

Technical Field

[0001] This utility model relates to the field of rapid cooling technology for silicon carbide sintering furnaces, and more specifically, to a rapid cooling device for reaction sintering silicon carbide sintering furnaces. Background Technology

[0002] The reaction sintering silicon carbide sintering furnace is a large-scale high-temperature equipment, mainly used for the high-temperature sintering of silicon carbide cantilever propellers for solar photovoltaic equipment. After each processing cycle, the furnace needs to be cooled internally before the next processing cycle can begin. Therefore, a rapid cooling device is required to quickly cool the internal components. Existing rapid cooling devices have fixed connection end models, making connection to different external sintering furnaces cumbersome. They also lack suitable connection adjustment mechanisms, and these mechanisms have poor stability after adjustment. Furthermore, they lack suitable quick-locking mechanisms. In addition, the height of the rapid cooling device needs to be adjusted for different external installation heights, which is also cumbersome. Utility Model Content

[0029] Please see Figures 1-3 , Figure 5 and Figure 6 A rapid cooling device for a reaction sintering silicon carbide sintering furnace includes a housing 1. Compressors 2 are installed at both the upper and lower ends inside the housing 1. Connecting rods 3 connect the compressors 2 and the housing 1, and multiple connecting rods 3 are provided. A fan 4 penetrates the right end face of the housing 1, and a dust cover 5 is provided on the housing 1 corresponding to the fan 4. An exhaust pipe 6 penetrates the left end face of the housing 1, and a connecting seat 7 is rotatably installed at the upper end of the exhaust pipe 6. A connecting pipe 8 penetrates the outer end face of the connecting seat 7, and multiple connecting pipes 8 are arranged circumferentially relative to the connecting seat 7. The multiple connecting pipes 8 are of different models. Support legs 9 are provided at the four corners of the lower end face of the housing 1. Support sleeves 10 are slidably installed on the outer end faces of the multiple support legs 9. A base plate 11 is connected to the bottom end of the multiple support sleeves 10, and a limiting mechanism is provided on each of the multiple support sleeves 10 corresponding to the support legs 9.

[0030] In this embodiment, a suitable connecting pipe 8 is selected according to the usage requirements. The connecting seat 7 drives the suitable connecting pipe 8 to rotate to a suitable position, opens the control valve on the corresponding connecting pipe 8, closes the control valve on other connecting pipes 8, and the connecting pipe 8 used is installed and locked with the external pipeline through its own flange.

[0031] More specifically, the support sleeve 10 slides relative to the support leg 9 for adjustment. After the height is adjusted appropriately, the limiting mechanism tightens the adjustment. When the device is in use, the automatic control system starts the compressor 2 and the fan 4. After the cold air and air are mixed, they are transmitted to the sintering furnace connected to the outside through the air outlet pipe 6, the connecting seat 7 and the connecting pipe 8 to achieve rapid cooling.

[0032] Please see Figure 5 As one embodiment of the connecting seat 7: a sealed bearing 12 is provided inside the connecting seat 7 corresponding to the air outlet pipe 6.

[0033] Specifically, when the connecting seat 7 rotates relative to the air outlet pipe 6, the sealing bearing 12 ensures the rotation position and sealing effect.

[0034] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5As one embodiment of rotational locking: an adjusting ring 13 is slidably provided on the air outlet pipe 6, a locking rod 14 is provided on the upper end face of the adjusting ring 13, and multiple locking rods 14 are provided in the circumferential direction. A locking ring 25 is provided on the connecting seat 7, and locking holes 15 are provided on the locking ring 25 corresponding to multiple locking rods 14. A fixing ring 16 is provided on the air outlet pipe 6, and the fixing ring 16 is installed below the adjusting ring 13. A first spring 17 is provided between the fixing ring 16 and the adjusting ring 13. The first spring 17 is fitted on the outer end of the air outlet pipe 6. A locking block 18 is symmetrically provided on the inner wall of the adjusting ring 13, and a locking groove 19 is provided on the air outlet pipe 6 corresponding to two locking blocks 18. A gripping rod 20 is provided on the outer end face of the adjusting ring 13, and multiple gripping rods 20 are provided in the circumferential direction relative to the adjusting ring 13.

[0035] Specifically, before rotation adjustment, hold the gripping rod 20 and slide the adjusting ring 13 downward relative to the air outlet 6 to squeeze the first spring 17. The locking block 18 and the locking groove 19 cooperate to slide and guide, and the locking rod 14 is taken out from the locking hole 15. After rotation adjustment is completed, release the gripping rod 20, the first spring 17 rebounds, and drives the adjusting ring 13 and the locking rod 14 to slide upward and reset. The locking rod 14 and the locking hole 15 cooperate to lock the state after rotation.

[0036] Please see Figure 1 and Figure 6 As one implementation method for height adjustment: multiple limiting mechanisms each include a limiting rod 21 and a limiting ring 22. The limiting rod 21 is installed through the support sleeve 10. The support leg 9 has a limiting hole 23 corresponding to the limiting rod 21. Multiple limiting holes 23 are spaced apart. The limiting ring 22 is installed on the outer end of the limiting rod 21. A second spring 24 is connected between the multiple limiting rings 22 and the support sleeve 10. The second spring 24 is fitted on the outer end of the limiting rod 21.

[0037] Specifically, by grasping the limiting ring 22 and pulling the limiting rod 21 outward, the second spring 24 is stretched. After the height is adjusted appropriately, the limiting ring 22 is released, the spring retracts, and the limiting rod 21 is reset and inserted into the appropriate limiting hole 23 to achieve a tight fit for the height adjustment.

[0038] In summary, the overall equipment is in use:

[0039] When adjusting the height before use, adjust the overall height of the device according to the height of the connection position of the external sintering furnace. The support sleeve 10 slides relative to the support leg 9. Before sliding, grasp the limiting ring 22 and pull the limiting rod 21 outward. The second spring 24 is stretched. After the height adjustment is completed, release the limiting ring 22, the spring retracts, and the limiting rod 21 resets and inserts into the appropriate limiting hole 23 to achieve limiting and tightening of the installation.

[0040] When in the connection adjustment state, hold the gripping rod 20 and pull the adjusting ring 13 downward to compress the first spring 17. The locking block 18 and the locking groove 19 cooperate to guide the sliding. The locking rod 14 is taken out from the locking hole 15. The connecting seat 7 is rotated relative to the air outlet pipe 6 to adjust to a suitable position. Release the gripping rod 20, the first spring 17 rebounds, and the adjusting ring 13 drives the locking rod 14 to slide back to its original position. After the locking rod 14 is inserted into the corresponding locking hole 15, the locking operation is realized. The connecting pipe 8 is locked by cooperating with the external pipe through its own flange. The opening and closing of the control valves on the multiple connecting pipes 8 are adjusted. The connected connecting pipes 8 are then put into use.

[0041] When in cooling mode, the built-in control system starts the compressor 2 and fan 4. The cold air and air are mixed and delivered to the connecting seat 7 and connecting pipe 8 through the air outlet pipe 6. The air is then delivered to the connected sintering furnace through the connecting pipe 8 to achieve rapid cooling.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
