Description

Technical Field

[0001] This utility model relates to the field of sintering furnaces, specifically to a flat-top high-temperature sintering furnace. Background Technology

[0002] Currently, with the research and development of new materials in China, most new material products require high-temperature sintering furnaces for calcination and sintering treatment. There are also many types of high-temperature sintering furnaces, including vacuum furnaces, dome furnaces, and flat-top furnaces.

[0003] Currently, most domestically produced flat-top high-temperature sintering furnaces use a 90-degree right-angle connection between the side wall and the top, with holes around the top of the silicon molybdenum rods. These types of sintering furnaces commonly suffer from ceiling collapse and cracking and chipping between the holes of the silicon molybdenum rods, thus affecting the service life of the sintering furnace. Utility Model Content

[0004] To address the problem of cracking and chipping of the furnace top in existing flat-top sintering furnaces, this utility model proposes a flat-top high-temperature sintering furnace, the specific technical solution of which is as follows:

[0005] A flat-top high-temperature sintering furnace includes a side wall, a top wall, and several silicon molybdenum rods. The top wall has mounting holes through which the silicon molybdenum rods are mounted. Support blocks are arranged on both sides of the silicon molybdenum rods, and the support blocks are mounted on the side walls and provide support to the top wall.

[0006] Furthermore, the cross-section of the support block is trapezoidal.

[0007] Furthermore, the silicon molybdenum rods are divided into four groups, and correspondingly, there are also four groups of support blocks. The four groups of support blocks are arranged in an array along the four sides of the top wall. In any support block-silicon molybdenum rod group, a silicon molybdenum rod is arranged between adjacent support blocks.

[0008] Furthermore, within any support block-silicon molybdenum rod assembly, the projection of the space between two adjacent support blocks onto the lower plane of the top wall will cover the projection of the mounting hole for installing the silicon molybdenum rod located between them onto the lower plane of the top wall.

[0009] The beneficial effects of this utility model are as follows:

[0010] Setting support blocks on the side wall can protect and support the area near the mounting holes, solving the problem of cracking and falling off of the mounting holes, extending the service life of the top wall, and reducing production costs and equipment maintenance expenses; at the same time, it does not affect the normal use of the furnace space.

[0016] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0017] The present invention provides the following specific implementation scheme:

[0018] like Figure 1-3 As shown, this utility model provides a flat-top high-temperature sintering furnace, including a side wall 1, a top wall 2 and a plurality of silicon molybdenum rods 5. The top wall 2 and the side wall 1 are combined to form the heating chamber of the sintering furnace. The top wall 2 has mounting holes 4. The silicon molybdenum rods 5 for heating are mounted on the lower side of the top wall 2 through the mounting holes 4. Support blocks 3 are arranged on both sides of the silicon molybdenum rods 5. The support blocks 3 are mounted on the side wall 1 and provide support to the top wall 2 near the mounting holes 4.

[0019] Furthermore, the cross-section of support block 3 is trapezoidal.

[0020] Furthermore, the lower surface of the sidewall 1 is rectangular, and the silicon molybdenum rods 5 are divided into four groups. Correspondingly, there are also four groups of support blocks 3. The four groups of support blocks are arranged in an array along the four sides of the top wall 2. The silicon molybdenum rods 5 and support blocks 3 located on the same side form a support block-silicon molybdenum rod group. In any support block-silicon molybdenum rod group, a silicon molybdenum rod 5 is arranged between adjacent support blocks 3.

[0021] Furthermore, within any support block-silicon molybdenum rod group, the projection of the space between two adjacent support blocks 3 onto the lower plane of the top wall 2 will be used to cover the projection of the mounting hole 4 of the silicon molybdenum rod 5 located between them onto the lower plane of the top wall 2.

[0022] Furthermore, in the vertical direction, the height of support block 3 is 100mm.

[0023] A support block 3 is installed on the side wall 1 to protect and support the area near the mounting hole 4, solving the problem of cracking and falling off of the mounting hole 4, extending the service life of the top wall 2, reducing production costs and equipment maintenance expenses; at the same time, it does not affect the normal use of the furnace space.
