Description

Technical Field

[0001] The utility model relates to a sintering kiln, in particular to a wire shelf used for carrying heating elements in the kiln. Background Art

[0002] A sintering kiln is a continuous process kiln, particularly used for the sintering of magnetic materials, with a sintering temperature above 1000°C. Currently, sintering kilns use silicon-molybdenum rods as heating elements to heat the furnace. The heating elements are generally located on the roof of the kiln, and a wire shelf (a thin plate made of refractory material) is provided in the roof structure, on which the heating elements are supported. For example, the wire shelf support structure of a push-plate kiln disclosed in publication number CN204987888U includes: a plurality of beams arranged perpendicular to the length of the kiln, with the ends of each beam respectively fixed to the two side walls of the kiln; a plurality of wire shelves for supporting the heating elements, with each wire shelf being arranged on a corresponding beam; and a plurality of central pillars for supporting the beams, with each central pillar being vertically arranged in the center of the kiln.

[0003] In order to meet the high-temperature sintering in the sintering furnace, the temperature of the heating element itself is often higher. In order to prevent the high-temperature heating element from sticking to the wire shelf, it is usually necessary to spread silicon crystal stone powder on the surface of the wire shelf. However, due to the air flow disturbance in the kiln, the silicon crystal stone powder on the wire shelf gradually spreads less, which eventually causes the heating element to stick to the wire shelf, which is not conducive to the extension of the silicon molybdenum rod and causes breakage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wire shelf structure for a sintering furnace in response to the above-mentioned prior art, and to reduce the adhesion between the heating element and the wire shelf by reducing the contact area between the two.

[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: a wire shelf of a sintering kiln, including a base plate, characterized in that: a support is provided on the surface of the base plate, the support is higher than the surface of the base plate, a plurality of the supports are spaced apart along the length direction of the base plate for supporting heating elements, and a plurality of rows of the supports are spaced apart along the width direction of the base plate for supporting multiple heating elements.

[0006] As an embodiment, the support platform is in an elongated strip shape, and the length direction of the support platform structure is perpendicular to the length direction of the substrate, so that the heating element can be reliably supported on the support platform surface.

[0007] As an embodiment, the distance between the support surface of the support platform and the surface of the substrate is 3-10 mm, so that the heating element is free relative to the substrate surface and sufficient heat dissipation space is left.

[0008] As an embodiment, the interval between adjacent pallets along the length direction of the substrate is 50-60 mm.

[0009] As an implementation manner, the distance between adjacent said supporting platforms along the width direction of the substrate is 70 - 80 mm.

[0010] As an implementation manner, at least one stopper is arranged between adjacent two columns of supporting platforms, and a distance of 40 - 60 mm is respectively reserved between the stopper and the supporting platforms on both sides along the width direction of the substrate. The function of the stopper is to separate the heating elements to avoid contact and collision between the heating elements on both sides.

[0011] Compared with the prior art, the advantages of the present utility model are as follows: The present utility model arranges supporting platforms on the surface of the wire laying plate, and uses the supporting platforms to support the heating elements (silicon molybdenum rods), so that the wire laying plate is vacated relative to the substrate, improving the heat generation efficiency of the heating elements, being beneficial to the extension of the heating elements, not easily breaking, and inhibiting and avoiding the adhesion between the heating elements and the wire laying plate.

[0015] The following further describes the present utility model in detail with reference to the drawings. The embodiments are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. The text description in this embodiment corresponds to the drawings, and the description of directions is also based on the drawings, and should not be construed as limiting the protection scope of the present utility model.

[0016] As Figures 1 - 3 shown, the wire laying plate of the sintering kiln furnace in this embodiment includes a substrate 1, the thickness of the substrate 1 is 20 mm, the length is 310 mm, and the width is 200 mm. A supporting platform 2 is arranged on the surface of the substrate 1, the supporting platform 2 is 5 mm higher than the surface of the substrate 1, the supporting platform 2 is strip-shaped, 24 mm long, and a plurality of supporting platforms 2 are distributed at intervals along the length direction of the substrate 1 to form a column for supporting one heating element (silicon molybdenum rod), and multiple columns of supporting platforms 2 are distributed at intervals along the width direction of the surface of the substrate 1 for supporting multiple heating elements.

[0017] The centers of adjacent two supporting platforms in the same column of supporting platforms are 60 mm apart, and adjacent two columns of supporting platforms are horizontally aligned, and the centers of the horizontally aligned two supporting platforms are 80 mm apart.

[0018] A stopper 3 is provided on the surface of the substrate 1. The shape of the stopper 3 is consistent with that of the support 2. The stopper 3 is located between two adjacent rows of supports, and the stopper 3 is not horizontally aligned with the support 2. In this embodiment, the stopper 3 is located in the middle position at the ends of the two rows of supports. When an abnormal situation occurs in which the heating element rolls off the support, the stopper 3 can prevent collision and contact between the two heating elements.

[0019] The wire shelf of the above structure adopts a support structure to support the heating element, so that the heating element is free relative to the substrate, effectively avoiding the adhesion of the heating element to the wire shelf, improving the heating efficiency of the heating element, and being conducive to the extension of the silicon-molybdenum rod, and the silicon-molybdenum rod is not easy to break.
