In large sintering furnaces, uneven heating of materials leads to a decline in sintering quality, especially as the material in the middle layer cannot receive sufficient radiant heat.
Design a storage rack with an inclined platform. The platform is evenly distributed from top to bottom, with the middle layer inclined outwards. Combined with the position of the heating source in the sintering furnace, this allows each layer of material to receive uniform radiant heat.
This ensures uniform heating of the materials and improves sintering quality.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of material placement technology in sintering furnaces, specifically relating to a storage rack in a large sintering furnace. Background Technology
[0002] The working principle of a sintering furnace is to control the atmosphere inside the furnace to achieve the sintering and hardening of ceramic materials. During the sintering process, the material is first placed into the furnace, and then the furnace temperature is raised to the required level using a heating device. The material is then transported to the furnace opening via a loading trolley, and fed into the furnace through rollers on the trolley and graphite plates installed inside the furnace, arranged neatly. After cleaning the dust inside the furnace, the furnace door is closed, and the vacuuming and heating processes begin.
[0003] To improve work efficiency, the furnace cavity is designed with a large volume to accommodate more materials to be processed. Generally, the materials are placed in a graphite support plate and heated inside the furnace. However, because the furnace is a vacuum environment, heat cannot be transferred through convection of the gas inside the furnace. That is, the heat transfer in the vacuum furnace is mainly radiant heat, which has a clear directionality. As the materials are stacked, the middle layer is blocked by the outer layer and cannot receive enough radiant heat, resulting in uneven heating of the materials and affecting the sintering quality. Utility Model Content
[0004] This utility model provides a storage rack for a large sintering furnace, which has a middle layer of the platform tilted outward at a certain angle so that each layer can receive uniform radiant heat. This ensures that the material is heated evenly and improves the sintering quality.
[0005] This utility model provides the following technical solution: a shelf in a large sintering furnace, comprising several support columns, with several load-bearing components inside the support columns. Each load-bearing component includes a loading platform, a first connecting seat, and a second connecting seat. The loading platforms are evenly distributed from top to bottom and are set at a certain tilt angle, tilting outward from the middle layer of the loading platform. There are heating sources at the top and sides of the sintering furnace, with the heating source located on the side facing the tilted surface of the loading platform.
[0006] The support column is fixedly connected to a second connecting seat, which has an adjustment cavity.
[0007] The stage is rotatably disposed at one end within the adjustment cavity, and the stage is rotatably connected to the second connecting seat via a rotating shaft.
[0008] The support column is fixedly connected to a first connecting seat, which has a support cavity, and the other end of the platform is located in the support cavity.
[0009] The height of the support cavity is greater than the thickness of the platform, and the bottom end of the first connecting seat is threaded with a support bolt for supporting the position of the platform. The support bolt is made of graphite.
[0010] The beneficial effects of this utility model are:
[0011] The loading assembly includes a loading platform, a first connecting seat, and a second connecting seat. Several loading platforms are evenly distributed from top to bottom and are set at a certain angle, tilting outward from the middle layer of the loading platform. There are heating sources in the sintering furnace located above the support column and on the side. The heating source on the side is opposite to the tilted surface of the loading platform, so that the middle layer of the loading platform is tilted outward at a certain angle, so that each layer can receive uniform radiant heat. This ensures that the material is heated evenly and improves the sintering quality of the material.
[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-4 The present invention provides the following technical solution: it includes several support columns 1, and several load-bearing components 2 are provided in the support columns 1. The load-bearing components 2 include a load platform 21, a first connecting seat 22 and a second connecting seat 23. The several load platforms 21 are evenly distributed from top to bottom. The load platforms 21 are set at a certain tilt angle and tilt outward from the middle layer of the load platform 21. There are heating sources in the upper part and the side of the sintering furnace. The heating source located on the side is opposite to the tilted surface of the load platform 21.
[0019] In this implementation scheme: the loading assembly 2 includes a loading platform 21, a first connecting seat 22, and a second connecting seat 23. Several loading platforms 21 are evenly distributed from top to bottom, and are set at a certain tilt angle, tilting outwards from the middle layer of the loading platform 21. Heating sources are located above and on the sides of the support column 1 inside the sintering furnace. These heating sources can reach the temperature required for sintering materials inside the sintering furnace. The side heating sources face the tilted surface of the loading platform 21, while the top heating sources face the front of the loading platform 21. The heating sources are located inside the sintering furnace and can be directed at each layer of material, ensuring that the middle layer of the loading platform 21... The material is tilted outward at a certain angle so that each layer is not blocked and receives uniform radiant heat. This ensures that the material is heated evenly and improves the sintering quality. The position of the platform 21 can be controlled by the first connecting seat 22 and the second connecting seat 23. The platform 21 is adjusted according to the amount of material placed on it to prevent the material from accumulating at the lower end of the platform 21 due to a large angle. When adjusting, the platform 21 can be rotated directly in the adjusting cavity 231 and its position can be changed in the supporting cavity 221. The supporting bolt 24 restricts the position of the platform 21.
[0020] A second connecting seat 23 is fixedly connected inside the support column 1. The second connecting seat 23 has an adjustment cavity 231. One end of the platform 21 is rotatably set in the adjustment cavity 231. The tilt angle of the platform 21 can be easily adjusted by directly adjusting the rotation of the platform 21 in the adjustment cavity 231.
[0021] More specifically, one end of the stage 21 is rotatably disposed in the adjustment cavity 231, and the stage 21 is rotatably connected to the second connecting seat 23 via the rotating shaft 25; when adjusting, the stage 21 can be directly rotated in the adjustment cavity 231 via the rotating shaft 25 to change to the required tilt angle.
[0022] A first connecting seat 22 is fixedly connected inside the support column 1. The first connecting seat 22 has a support cavity 221. The other end of the platform 21 is located inside the support cavity 221. After adjusting the tilt angle of the platform 21, its position inside the support cavity 221 will also change, and its position will change within the support cavity 221, thus limiting the position of the platform 21.
[0023] The height of the support cavity 221 is greater than the thickness of the platform 21. The bottom end of the first connecting seat 22 is threaded with a support bolt 24 for supporting the position of the platform 21. After the tilt angle of the platform 21 is adjusted to the correct position, it is further restricted and fixed by the support bolt 24.
[0024] The rack is placed inside the sintering furnace, and there can be several racks. Due to the inclined arrangement of the platform 21, each layer of platform 21 on the rack can be irradiated by the heating source, that is, receive the radiant heat of the heating source. This avoids the situation where the side heating source cannot irradiate the platform 21 in the traditional horizontal arrangement, and further improves the uniformity of material heating.
