Technical Field

[0001] The utility model specifically relates to the technical field of porcelain boats, in particular to a double-layer porcelain boat for a high-temperature tube furnace. Background Art

[0002] In experiments such as gas phase sulfidation and phosphating, porcelain boats are usually used as reaction containers, and sulfur sources, phosphorus sources and other substances are placed upstream of the gas phase treatment. In the experiment, the contact area between the reactants and the reaction gas will affect the reaction results, and the existing porcelain boats are mostly single-layer designs. In the space where the gas flows, the reaction gas cannot fully contact and react with the reactants in the porcelain boat, that is, it flows to the outside, thereby affecting the test results of the reactants.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a double-layer porcelain boat for a high-temperature tube furnace, comprising:

[0005] The lower porcelain boat has a reaction slot 1 on the top for placing reactants;

[0006] An upper porcelain boat is arranged on the lower porcelain boat, a second reaction slot is arranged on the top of the upper porcelain boat, a partition is fixedly arranged in the reaction slot, and the partition can separate the second reaction slot into a smoke chamber and a storage chamber, wherein the smoke chamber occupies 1 / 3 of the volume of the second reaction slot, the storage chamber occupies 2 / 3 of the volume of the second reaction slot, and the smoke chamber can be connected with the first reaction slot and the storage chamber;

[0007] And a top cover, which is matched and pressed on the second reaction slot of the upper porcelain boat, and an exhaust hole is arranged at the right end of the top cover, and the exhaust hole is located above the storage cavity.

[0008] Further, preferably, the height of the partition is equal to 1 / 2 of the height of the upper porcelain boat.

[0009] Further, preferably, a protrusion is provided on the bottom surface of the upper porcelain boat to form a ring strip, and the ring strip can be matched and embedded in the reaction slot one.

[0010] Further, preferably, a plurality of evenly distributed smoke holes are provided on the bottom wall of the upper porcelain boat and located in the smoke cavity, and each of the smoke holes is located in the coil.

[0011] The utility model adopts the above technology and has the following beneficial effects compared with the existing technology:

[0012] 1. There are holes in one-third of the bottom of the upper porcelain boat, which can ensure that the volatilized gas from the lower porcelain boat passes through the smoke holes and fills the upper porcelain boat. There is a partition in the middle, and the height of the partition is half of the height of the upper porcelain boat, ensuring that the gas can enter the other side to react with the substance.

[0013] 2. A ring strip is arranged on the bottom surface of the upper porcelain boat, and the ring strip can be embedded in the reaction slot 1. On the one hand, it stabilizes the connection between the upper porcelain boat and the lower porcelain boat, and on the other hand, it can prevent the reaction gas from leaking out and make full use of the reaction gas.
