As shown in fig. 1 to 4, the receiving portion 2 in the present embodiment includes a plurality of inclined receiving plates 21, and specifically, the receiving portion 2 is formed by enclosing the plurality of inclined receiving plates 21;

Specifically, the inclined receiving plates 21 are in one-to-one correspondence with the side walls of the lining flues 1, the bottom end of each inclined receiving plate 21 is arranged at the top of the corresponding side wall of the lining flues 1, and each inclined receiving plate 21 is inclined outwards from bottom to top along the radial direction of the lining flues 1;

By adopting the design, before construction, workers can manufacture lining devices (inner side flues and bearing parts) with different sizes according to the inner diameter of a needed reserved opening, and after the manufacture is finished, the lining devices and the bearing parts are connected in an adhesion mode (such as gluing and other modes, namely, the lining devices and the bearing parts are fastened with each other), so that the lining devices are convenient to install; economic, reasonable and efficient;

In other embodiments, the inner flue and the receiving part can be connected by welding;

Or in other embodiments, the connection between the inner chimney and the receptacle may be made by bending, folding or locking the shape of the object.

Preferably, the sealing connection part 3 in this embodiment is a fireproof sealant, and the fireproof sealant has the following advantages:

(1) Excellent fireproof performance: the fireproof sealant has high fireproof performance, can effectively inhibit flame spreading and smoke generation, can form a high-temperature resistant sealing layer at high temperature, and can prevent fire spreading to other areas, so that the fireproof performance of a flue is ensured;

(2) High temperature resistance is good: the fireproof sealant can keep stable performance in a high-temperature environment, cannot be melted or lose efficacy due to high temperature, can provide long-time fireproof protection when a fire disaster occurs, and cannot generate toxic gas so as to ensure the connection stability between the inner side flues;

(3) The weather resistance is strong: the fireproof sealant has good weather resistance, can be used for a long time under different climatic conditions without being influenced, can resist corrosion of factors such as ultraviolet rays, wind and rain, oxidation and the like, and can maintain a long-term fireproof effect so as to ensure the service life of an inner flue;

(4) Good isothermicity: the isothermal properties of the fire-resistant sealants are good, i.e., relatively stable physical and chemical properties are maintained at different temperatures. The fire-proof device is not affected by temperature change, and can correctly play a fire-proof role in a wide temperature range, so that the fire-proof performance of the flue is ensured;

If α is greater than this range, the gap between the support portion 2 and the lining flue 1 is too large, and the too large gap may cause insufficient filling or uneven dispersion of glue, so that the bonding area between the support portion 2 and the lining flue 1 is reduced, thereby reducing the strength and stability of the connection, which may result in an increased risk of loosening, falling or breaking the connection;

Further, an excessive gap may cause the fireproof sealant to be not effectively sealed between the support 2 and the lining flue 1, thereby possibly causing leakage of liquid or gas, possibly causing a safety problem, and causing a decrease in system performance;

Further, too large a gap may require more fire-resistant sealant to fill, which increases cost and waste, while too much fire-resistant sealant may increase the difficulty of cleaning and maintenance after bonding.

If α is smaller than this range, the gap between the support portion 2 and the lining flue 1 is too small, and the too small gap may cause difficulty in fully filling and distributing the fireproof sealant, so that the adhesion effect between the lining flues 1 is poor, thereby affecting the strength and stability of the connection;

Further, too small a gap may cause excessive stress applied when the fire-resistant sealant is filled, resulting in cracking or damage of the support 2 and the lining flue 1, which may affect the reliability and life of the entire connection;

further, too small a gap may increase difficulty in mounting and dismounting, may require the application of more force or the use of special tools, and may further make it more difficult to maintain and clean the connection members.

Proper gap size is very important for glue filled joints, proper gap can achieve good filling and distribution, and strength, stability and tightness of the joint are improved to the greatest extent.

if L and D are greater than this range, the length of the receiving portion formed by enclosing the inclined receiving plate 21 is too long, which occupies unnecessary space, increases the size and weight of the inner flue, which may result in waste of resources and increase of manufacturing cost, and causes space waste:

Further, excessive length may make the installation and removal of the liner stack difficult, requiring more space and tools to operate.

Further, excessive bay length may result in stress concentrations between lining flues, especially in the case of torsion or compression, which may increase the vulnerability of the connection and the risk of failure.

If L and D are less than this range, too little land length may not provide sufficient connection strength and stability, which may lead to loosening, sloughing, or breakage between lining flues;

Further, too small a joint length may result in a reduced contact area between the lining flues, making the connection unstable, which may result in small movements or loosening of the lining flues under vibration or external forces;

Further, too small a land length may be critical to control dimensional tolerances of the liner stack, making the manufacturing and assembly process more difficult.

Therefore, when designing the receiving part, the length of the receiving part needs to be reasonably controlled according to the length of the lining flue, and the length needs to be reasonably planned according to specific application and connection requirements so as to ensure the strength, stability and reliability of connection. A proper length can achieve a good connection effect, and meanwhile unnecessary resource waste and manufacturing complexity are avoided;

(2) Reliable connection: the plate-shaped side walls provide a larger connection contact area, and can realize more reliable connection, so that the connection is more compact and firm.

(3) Easy to process and manufacture: the machining and manufacturing of the plate-shaped side walls is relatively simple compared to complex shapes (e.g. arcs), and the plate-shaped structure is generally easier to achieve by machining processes such as cutting, bending, stamping, etc.

In other embodiments, the cross section of the inclined receiving plate 21 is formed in an arc shape, and the inclined receiving plate 21 has the advantage of being in an arc shape:

(1) Uniform stress distribution: the curved sidewalls may provide a more uniform stress distribution, particularly under external forces such as loading or vibration, which may help to mitigate stress concentrations and improve the life and reliability of the connection.

(2) Stress concentration is reduced: the shape of the curved side walls is such that no sharp edges or taper angles are created during the nesting process, thereby reducing the risk of stress concentrations, which helps to prevent cracking and localized damage.

(3) Accommodation error: the curved side walls are designed to accommodate dimensional deviations or manufacturing tolerances of the connecting members to some extent, which provides some flexibility and adaptability to make the connection easier.

The appropriate shape may be selected according to the actual assembly requirements.

As shown in fig. 1 to 4, the susceptor 2 and the lining flue 1 in the present embodiment are made of the same material, and are designed such that the susceptor 2 and the lining flue 1 have similar physical properties including thermal expansion coefficient, strength, rigidity, etc., which means that they may respond in a similar manner under temperature and stress changes, thereby reducing engineering problems caused by mismatched materials;

Further, if the inner flue and the receiving portion are made of the same corrosion resistant material, such as stainless steel, they may all have similar corrosion resistance properties, which is critical to the flue system because the flue is often exposed to high temperature, humidity, and corrosive gases, etc.;

Further, the use of the inner flue and the receiving portion of the same material simplifies the design and construction process, and because they have the same material properties, the proper assembly and connection can be more easily selected, and complex material-to-material conversions are reduced.

Further, the inner flue and the receiving part of the same material can improve the performance consistency of the system, have the same thermal characteristics and mechanical characteristics, and can better cooperate to improve the performance and stability of the whole flue system.

Specifically, the assembly process of the interlayer interface structure of the lining flue comprises the following steps:

The inner lining flue 1 of the layer is fixedly assembled firstly, then fireproof sealant is fully filled around the inner side wall of the receiving part 2, before the glue curing time is reached, the receiving part 2 on the lower inner lining flue 1 is jointed with the bottom of the inner lining flue 1, and after the glue is cured, the two inner lining flues 1 can be completely and hermetically connected.
