A fully sealed furnace body of a heating furnace

Abstract

The present invention provides a fully sealed furnace body for a heating furnace, comprising a furnace shell, a furnace frame, ceramic plates, and ceramic seals. The furnace shell is rectangular and has an inner cavity. The furnace frame is disposed in the inner cavity and abuts against the inner wall of the furnace shell. The furnace frame comprises a square outer frame and a furnace bottom plate that divides the inner cavity into a plurality of furnace chambers. The furnace bottom plate is horizontally fixed within the outer frame. The ceramic plates are arranged in a straight line on the furnace bottom plate. The cross-section of the ceramic plates is convex, and the sides of adjacent ceramic plates are closely attached to each other. The ceramic seals are disposed in grooves between adjacent ceramic plates and cover the gaps between the two ceramic plates. The layers of the furnace chambers are completely sealed from each other, and the gaps between the ceramic plates are blocked by the ceramic seals to prevent heat flow disturbances in the upper and lower furnace chambers.

Description

Technical Field

[0001] The invention belongs to the technical field of heating furnaces and relates to a fully sealed furnace body of a heating furnace. Background Art

[0002] When the heated sheet is relatively low, if the furnace chamber is relatively high, a large amount of heat will be wasted during heating due to the excessive space. Therefore, the single large chamber can be divided into separate, enclosed chambers, saving space and energy. This allows for simultaneous heating of multiple sheets, and each chamber can be independently temperature-controlled without interfering with each other. However, the metal divider, which expands at high temperatures, is used to support the sheet and seal the chamber. This expansion of the divider causes the ceramic sheets to shift, creating gaps between adjacent sheets. This can cause heat flow disturbances in the upper and lower chambers, making precise temperature control impossible and reducing the insulation effect. Summary of the Invention

[0003] The purpose of the present invention is to address the above problems in the existing technology and propose a fully sealed furnace body of a heating furnace, in which the layers of the furnace are completely sealed from each other, thereby improving the sealing effect of the furnace and preventing the furnaces from interfering with each other.

[0004] The objectives of the present invention can be achieved through the following technical solutions: a fully sealed furnace body of a heating furnace, characterized in that it includes a furnace shell, a furnace frame, a ceramic plate, and a ceramic seal. The furnace shell is rectangular and has an inner cavity. The furnace frame is arranged in the inner cavity and is in contact with the inner wall of the furnace shell. The furnace frame includes a square outer frame and a furnace bottom plate that divides the inner cavity into several furnace chambers. The furnace bottom plate is horizontally fixed in the outer frame. The ceramic plates are arranged in a line on the furnace bottom plate. The cross-section of the ceramic plates is "convex" shaped. The sides of adjacent ceramic plates are tightly attached to each other. The ceramic seal is arranged in the groove between adjacent ceramic plates and covers the gap between the two ceramic plates.

[0005] Furthermore, the ceramic seal is in the shape of an elongated strip with a rectangular cross section.

[0006] Furthermore, the ceramic seal is in the shape of an elongated strip, and its cross section is an equilateral triangle.

[0007] Furthermore, the ceramic sealing member has the same length as the ceramic plate.

[0008] Furthermore, the height of the ceramic seal is equal to one quarter of the height of the ceramic plate.

[0009] Compared with the existing technology, the fully sealed furnace body of this heating furnace has the following advantages:

[0010] 1. The layers of the furnace are completely sealed with each other, and the gaps between the ceramic plates are blocked by ceramic seals to prevent heat flow disturbance between the upper and lower furnaces.

[0011] 2. The large furnace is divided into multiple independently sealed small furnaces, and the temperature of each furnace is independently controlled without interfering with each other, so that multiple pieces with different temperature requirements can be heated at the same time.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0017] Example 1

[0018] like Figure 1 、 Figure 2 As shown, the fully sealed furnace body of the heating furnace includes a furnace shell 1, a furnace frame 2, a ceramic plate 3, and a ceramic seal 4. The furnace shell 1 is in the shape of a rectangular parallelepiped and has an inner cavity. The furnace frame 2 is arranged in the inner cavity and is in contact with the inner wall of the furnace shell 1. The furnace frame 2 includes a square outer frame 21 and a furnace bottom plate 22 that divides the inner cavity into several furnace chambers. The furnace bottom plate 22 is horizontally fixed in the outer frame 21. The ceramic plates 3 are arranged in a line on the furnace bottom plate 22. The cross-section of the ceramic plates 3 is in the shape of a "convex" character. The sides of adjacent ceramic plates 3 are tightly attached to each other. The ceramic seal 4 is arranged in the groove between adjacent ceramic plates 3 and covers the gap between the two ceramic plates 3.

[0019] The ceramic seal 4 is in the shape of an elongated strip with a rectangular cross section. The length of the ceramic seal 4 is the same as that of the ceramic plate 3 , and the height of the ceramic seal 4 is equal to one quarter of the height of the ceramic plate 3 .

[0020] The ceramic seal 4 is placed between two adjacent ceramic plates 3 to seal the gap between the ceramic plates 3 to prevent the heat of the furnace bottom plate 22 below the ceramic plates 3 from rising from the gap and affecting the temperature of the furnace at this layer.

[0021] Example 2

[0022] like Figure 3 As shown, the ceramic seal 4 is in the shape of an elongated strip, and its cross section is an equilateral triangle.

[0023] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
