AI Technical Summary
During the operation process, the existing heating furnace inner barrels are poor in stability due to rigid contact connections, which easily generate vibration and cause noise.
A new type of inner barrel is designed, which is provided with an annular projecting convex edge near the upper end on the outer side of the body, and a flexible sealing ring is installed at the upper end. The outer diameter of the sealing ring is larger than the convex edge and has an annular concave sealing groove to avoid rigid contact between the inner barrel and the outer shell and absorb vibration through the sealing ring.
It effectively avoids the connection gap between the inner barrel and the outer shell, improves the stability of the heating furnace, and reduces vibration and noise through the buffering effect of the sealing ring.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to a new inner barrel of a heating furnace. Background Art
[0002] The inner barrel of the heating furnace, also often called the furnace, furnace tube or reaction chamber, is one of the core components of the heating furnace. Its main function is to provide a controlled heating environment for the material in a closed or semi-closed space.
[0003] The inner barrel of the heating furnace is a key component to ensure that the heating process is efficient, safe and in compliance with specific process requirements. Its design and manufacturing quality directly affects the efficiency of the entire heating process and the quality of the product.
[0004] The existing inner barrel is usually cylindrical and directly connected to the outer shell of the heating furnace by rigid contact. The connection stability is relatively poor. In addition, the inner barrel may vibrate during operation because it is not stably positioned, resulting in poor stability. The vibration during operation also generates noise. Summary of the invention
[0005] The purpose of the utility model is to provide a new inner barrel of a heating furnace with high stability and compact structure in view of the above problems existing in the prior art.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A new inner barrel of a heating furnace comprises a cylindrical body, the lower end of the body is closed and the upper end is open, and the characteristic is that the outer side of the body has an annular protruding ridge close to the upper end of the body, and also comprises a flexible sealing ring, the above-mentioned sealing ring is sleeved on the body and the lower part of the sealing ring abuts against the ridge, the outer diameter of the sealing ring is larger than the outer diameter of the ridge, and the upper part of the sealing ring has an annular concave sealing groove.
[0008] The new inner barrel of the heating furnace creatively sets a ring-shaped protruding convex edge on the outer side of the body near its upper end. After the sealing ring is sleeved on the body, the convex edge stably supports the lower part of the sealing ring. Such a structure can ensure that the sealing ring is stably located at the upper end of the body.
[0009] After the inner barrel and the outer shell are installed, the sealing ring is tightly pressed between the inner barrel and the outer shell. Such a structure can avoid rigid contact between the inner barrel and the outer shell.
[0010] Specifically, since the outer diameter of the sealing ring is larger than the outer diameter of the flange, the outer edge of the sealing ring extends out of the flange. During installation, the outer edge of the sealing ring is squeezed, and the outer edge of the sealing ring is folded to cover the outer side of the flange, and the folded part of the sealing ring is tightly pressed between the inner barrel and the outer shell. Such a structure can effectively avoid rigid contact between the inner barrel and the outer shell, and the vibration during the operation of the heating furnace can also be absorbed and buffered by the sealing ring, further improving its stability.
[0011] In addition, the provision of the sealing groove can enable the outer edge of the sealing ring to be folded more stably.
[0012] In the novel inner barrel of the heating furnace, along the axial direction of the body, the sealing groove is located inside the convex edge and is adjacent to the outer edge of the convex edge.
[0013] After the outer edge of the sealing ring is squeezed by the outer shell, the outer edge can be stably folded downward.
[0014] In the novel inner barrel of the heating furnace described above, the size of the sealing groove at the end is larger than the size of its bottom.
[0015] Such a structure can facilitate the outer edge of the sealing ring to be stably folded after being subjected to force.
[0016] In the novel inner barrel of the above-mentioned heating furnace, the flange and the body are an integrated structure.
[0017] This can appropriately improve the structural compactness of the inner barrel.
[0018] In the novel inner barrel of the heating furnace, the number of the sealing grooves is several, and the several sealing grooves are arranged from inside to outside with the same center as the axis of the body.
[0019] The arrangement of multiple sealing rings can make the sealing rings fold downward more stably when subjected to force.
[0020] In the novel inner barrel of the above-mentioned heating furnace, the depth dimension of the sealing groove is 1 / 4-1 / 3 of the thickness dimension of the sealing ring.
[0021] Such a structure can ensure the strength of the sealing ring while also enabling the sealing ring to fold stably after being stressed.
[0022] In the novel inner barrel of the heating furnace described above, the opening end of the sealing groove has a smoothly transitioned deformation portion.
[0023] In the novel inner barrel of the heating furnace described above, the deformation portion is a chamfer at the opening end of the sealing groove.
[0024] In the novel inner barrel of the heating furnace described above, the deformation portion is a rounded corner at the opening end of the sealing groove.
[0025] The deformation part has two functions:
[0026] First, eliminate the angular structure at the end of the sealing groove;
[0027] Secondly, the size of the upper end of the sealing groove is made larger than the size of the bottom of the sealing groove, so that the outer edge of the sealing ring can be stably folded when subjected to force.
[0028] In the novel inner barrel of the heating furnace described above, the length dimension of the sealing ring extending out of the flange is smaller than the thickness dimension of the flange.
[0029] Such a structure can prevent too many sealing rings from being pressed between the flange and the outer shell. When an appropriate amount of sealing rings are pressed between the flange and the outer shell, the inner barrel can be stably positioned in the outer shell.
[0030] Compared with the prior art, the new inner barrel of the heating furnace has a structure that, when the inner barrel is connected to the outer shell, the outer edge of the sealing ring can be stably folded downward after being squeezed by the outer shell, and the folded portion of the sealing ring is tightly pressed between the convex edge and the outer shell. Such a structure can effectively eliminate the connection gap between the inner barrel and the outer shell, and the sealing ring that is tightly pressed during operation can also play a buffering role, effectively improving the stability of the heating furnace with the inner barrel.
[0031] At the same time, the sealing ring can be directly put on the main body, so the entire inner barrel structure is relatively simple, compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
