Description

Technical Field

[0001] This utility model relates to the field of high-temperature baking equipment technology, and in particular to the outer shell of a heating tube furnace. Background Technology

[0002] The heating tube furnace body heats the raw materials inside a quartz shroud to produce sintered objects. The outer shell of the heating tube furnace body is subjected to prolonged high-temperature baking, making it highly susceptible to oxide scale formation. When the furnace is opened, the change in room temperature causes this oxide scale to flake off, making it extremely easy to contaminate the sintered objects inside the quartz shroud when handling them. This renders the outer shell unusable when large-scale oxide scale flakes occur. Furthermore, the prolonged transition between high and low temperatures makes the shell prone to cracking, leading to insufficient sealing during the product sintering process. Summary of the Invention

[0003] This utility model provides an outer shell for a heating tube furnace to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this utility model provides an outer shell for a heating tube furnace, comprising a shell with openings at both ends and an annular base installed at the openings at both ends of the shell.

[0005] The bottom of the annular base is provided with a groove, and a sealing sheet is provided in the groove. A sealing channel is formed between the inner wall of the groove and the sealing sheet.

[0006] The port of the sealed channel is connected to a cooling device, which introduces coolant into the sealed channel.

[0007] Preferably, the annular base is made of stainless steel.

[0008] Preferably, the groove is arranged circumferentially along the annular base.

[0009] Preferably, the sealing sheet is made of stainless steel.

[0010] Preferably, the sealing sheet is welded and fixed to the groove.

[0025] The outer shell of the heating tube furnace body provided by this utility model, such as Figures 1 to 3 As shown, the furnace includes a shell 10 with openings at both ends and an annular base 20 installed at the openings at both ends of the shell 10. The annular base 20 serves as a support for the overall furnace body and is connected to the bottom cover (not shown) at the bottom, so that the bottom cover and the shell form a sealed cavity. The sintering purpose is achieved by heating the sealed cavity.

[0026] The bottom of the annular base 20 is provided with a groove 30, and a sealing sheet 31 is provided in the groove 30. A sealing channel is formed between the inner wall of the groove 30 and the sealing sheet 31.

[0027] The ports of the sealed channel are respectively connected to a cooling device (not shown). The cooling device introduces coolant into the sealed channel, thereby keeping the outer shell at a low temperature during use. Even if the furnace is frequently opened during the product process operation, it will not affect the normal use of the outer shell.

[0028] In some embodiments, the annular base 20 may be made of stainless steel, and the sealing sheet 31 may also be made of stainless steel. The sealing sheet 31 may be welded and fixed to the groove 30 to ensure that the formed sealing channel is unobstructed and leak-free.

[0029] In some embodiments, please refer to Figures 1 to 3 The groove 30 is arranged around the circumference of the annular base 20 to ensure uniform cooling at both ends of the entire shell and improve the cooling effect.

[0030] In some embodiments, please refer to the following: Figure 3 The bottom surface of the sealing sheet 31 is flush with the bottom surface of the annular base 20; the port of the sealing channel is connected to an inlet / outlet interface 32, one end of the inlet / outlet interface 32 is connected to the port of the sealing channel, and the other end protrudes from the upper surface of the annular base 20. This ensures that the setting of the sealing channel will not affect the installation and support function of the annular base 20, and also ensures the aesthetics of the annular base 20.

[0031] In some embodiments, please refer to the following: Figure 1The inlet / outlet interface 32 is positioned close to the cooling equipment to facilitate communication between the cooling equipment and the sealed channel, thereby reducing messy wiring.

[0032] In summary, the outer shell of the heating tube furnace body provided by this utility model includes a shell 10 with openings at both ends and an annular base 20 installed at the openings at both ends of the shell 10. A groove 30 is formed at the bottom of the annular base 20, and a sealing plate 31 is provided within the groove 30. A sealing channel is formed between the inner wall of the groove 30 and the sealing plate 31. The ports of the sealing channel are respectively connected to a cooling device, which supplies coolant into the sealing channel. This utility model, by adding coolant pipes to the annular base 20 at both ends of the shell 10, effectively avoids drastic temperature fluctuations caused by the heating and cooling of the high-temperature furnace body, thus preventing the shell temperature from becoming extremely cold or hot. Thanks to this optimized temperature control, the service life of the shell is significantly improved, specifically extended from approximately 2 years to approximately 4 years, greatly improving the durability and economy of the equipment.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
