Description

Technical Field

[0001] This utility model relates to the field of heat exchanger tube processing, and in particular to a tube sintering kiln furniture. Background Technology

[0002] In the pressureless sintering process for preparing silicon carbide tubing, typically only one layer of tubing can be sintered at a time. High temperatures densify the silicon carbide tubing, increasing its structural strength and forming the tubing. In actual production, large quantities of silicon carbide tubing are often required to meet market demand. However, the limited output per sintering layer necessitates frequent loading, sintering, and unloading operations, significantly increasing the production cycle and reducing efficiency. Furthermore, uneven temperature distribution during pressureless sintering is a major cause of tubing deformation, and even with one layer sintered at a time, temperature unevenness can still occur.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4An embodiment of this utility model is provided: a pipe sintering kiln, comprising: a kiln body 1; a plurality of troughs 2 provided on the kiln body 1 for placing pipes 3; at least one or more kiln bodies 1 are stacked to hold a plurality of pipes 3.

[0027] In this embodiment, by setting several troughs 2 inside the kiln body 1 for placing the tubes 3 for sintering, multiple kiln bodies 1 can be heated simultaneously. The designed shape of the troughs 2 makes the tubes 3 heat more evenly and reduces the problem of tube deformation. The material of the tubes 3 is silicon carbide, and the material of the kiln body 1 is graphite.

[0028] The kiln furniture body 1 includes a base 11, and the two sides of the base 11 extend upward to form side plates 12.

[0029] In this embodiment, the height of the side plate 12 is higher than the diameter of the pipe 3. When the pipe 3 is placed inside the tank 2, it avoids squeezing the pipe 3 and causing deformation of the pipe 3.

[0030] The upper end face of the side plate 12 is provided with an upwardly extending protrusion 121; the lower end face of the side plate 12 is provided with an upwardly opening groove 122; two adjacent kiln furniture bodies 1 are engaged by the protrusion 121 and the groove 122.

[0031] In this embodiment, by providing protrusions 121 and grooves 122 on the side plate 12, the stacked kiln furniture bodies 1 are matched in a limiting manner to prevent misalignment of the kiln furniture bodies 1 from causing compression of the pipe 3.

[0032] Several first connecting grooves 123 are provided on the two side plates 12.

[0033] In this embodiment, by setting the first connecting groove 123, the temperature can be quickly conducted to the groove 2 inside the kiln body 1 to heat the pipe 3, so that the pipe 3 in the middle and the pipes 3 on both sides are heated at the same time, ensuring uniform heating.

[0034] Several parallel grooves 2 are provided on the base 11 for placing pipes 3.

[0035] The trough 2 includes a support section 21 and a connecting section 22. The support section 21 is an inclined surface, and the connecting section 22 is an arc surface with an arc of 60°-110°.

[0036] In this embodiment, the support sections 21 on both sides contact the pipe 3, and there is a certain gap between the connecting section 22 and the pipe 3, so that the pipe 3 and the tank 2 are in line contact, increasing the heating area of ​​the pipe 3. The curvature of the connecting section 22 is 60°-110°, preferably 90°, so that the pipe 3 is not easily deformed, and the sintered pipe 3 can ensure good roundness and curvature.

[0037] Two adjacent tanks 2 are directly connected by a support section 21 or by a partition plate 4.

[0038] In this embodiment, the tank 2 is either continuously arranged or separated by partitions 4. The continuously arranged tank 2 makes the heating temperature of the pipe 3 more uniform. By setting partitions 4, the kiln furniture body 1 has greater support, allowing more kiln furniture bodies 1 to be stacked and more pipes 3 to be sintered at one time.

[0039] A second connecting groove 41 is provided on the partition 4.

[0040] In this embodiment, if a partition 4 is provided, a second connecting groove 41 is opened on the partition 4. The number and position of the second connecting groove 41 correspond to the position of the first connecting groove 123, so that heat can be conducted quickly.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
