Description

Technical Field

[0001] The utility model relates to the technical field of biomass hot blast stoves, in particular to a Shakron interface for biomass hot blast stoves. Background Art

[0002] Cyclone separator is a highly efficient gas-solid separation device that uses the centrifugal force principle to separate solid particles from the gas. In the hot blast furnace system, cyclone separator plays a vital role, mainly used to capture and separate the smoke and particulate matter generated during the operation of the hot blast furnace to ensure that the exhaust gas meets the strict requirements of environmental protection and effectively protect the subsequent processing equipment from potential damage caused by particulate matter.

[0003] Therefore, the design and connection method of the Shaklon interface are directly related to the operating performance and stability of the entire system. The Shaklon interface is a key link in the production design of hot blast furnaces. At present, the Shaklon interface is generally installed with a flange structure, which provides two main installation methods:

[0004] The first is welding installation. This installation method can provide a stable connection, but the welding process is time-consuming, and the high heat generated during the welding process may cause thermal deformation at the Shakron interface, thereby affecting the sealing of the interface and the overall performance of the equipment.

[0005] The second is the flange butt installation method, which is to connect the two flanges tightly together by bolts. However, there is a significant problem with this connection method: although the flanges can fit tightly, the bolt connection will inevitably leave a small gap between the flanges. These gaps may become potential channels for smoke and particulate matter to leak. In order to compensate for this defect, airtight fillers are usually filled in the gaps to improve the sealing. However, these fillers may gradually fail during use due to various factors (such as temperature differences in the working state of the hot air furnace), and their airtightness effect will deteriorate over time. What's more serious is that under extreme temperature conditions, the fillers may be deformed or even damaged due to the influence of high temperature pressure or thermal expansion and contraction, which will adversely affect the stability and performance of the entire system.

[0006] Therefore, we provide Shaklon interface for biomass hot air furnace to solve the above problems. Utility Model Content

[0007] In view of the problems existing in the above-mentioned prior art, the utility model provides a Shakron interface for a biomass hot air furnace, which realizes efficient production and reliable sealing of the equipment through modular design and optimized sealing structure, thereby greatly improving production efficiency, reducing maintenance costs, and ensuring the stability and safety of the equipment in long-term operation.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts a Shakron interface for a biomass hot air furnace, comprising a main shell and an auxiliary shell, wherein the Shakron connection port of the main shell is connected to the connection port of the auxiliary shell through a connection assembly, wherein the connection assembly comprises two relatively arranged flanges, wherein the two flanges are fixed by bolts, and the bolt connection mode has greater flexibility, allowing fine adjustment during assembly, and a gap is left at the connection between the two flanges, wherein two elastic members are relatively arranged and installed at the gap, wherein one side of the elastic members is in contact with the flange, and a first sealing member is installed between the two elastic members, and one side of the first sealing member is in contact with the elastic member, thereby effectively preventing leakage of gas or particulate matter, wherein:

[0009] The elastic member includes a pressing part, a raised part and a plane part from the outside to the inside, the pressing part is arc-shaped and the inner concave surface of the pressing part contacts the outer circumferential surface of the first seal and squeezes the first seal, one end of the raised part is connected to the pressing part and the other end is connected to the plane part, an annular groove for accommodating the raised part is provided on the flange, the raised end of the raised part is arranged in the above-mentioned annular groove, and the plane part is arranged parallel to the above-mentioned first seal to ensure that when the first seal is deformed, the elastic member can provide uniform and sufficient extrusion force, thereby improving the sealing effect.

[0010] The first seal includes a pressure-bearing portion and a sealing portion, wherein the pressure-bearing portion is arranged in coordination with the above-mentioned pressing portion, the sealing portion extends inwardly along the pressure-bearing portion and one side of the sealing portion contacts the flange while the other side contacts the sealing portion arranged oppositely, the pressure-bearing portion is arc-shaped and is arranged parallel to the pressing portion, and a double arc structure is adopted to ensure the coordination effect between the pressure-bearing portion and the pressing portion, thereby improving the sealing ability of the first seal, and in order to further enhance the extrusion effect, the above-mentioned bolts can also be designed to sequentially penetrate the flange, the pressing portion and the pressure-bearing portion along a penetration path.

[0011] As a further optimization of the above scheme, the elastic member is annular or fan-shaped. When the elastic member is fan-shaped, the number of the elastic members in the same circumferential direction is multiple and arranged in a circular array with equal spacing. Therefore, the utility model provides a new type of sealing structure by introducing two different designs of elastic members, annular and fan-shaped. The annular design simplifies the installation process, while the fan-shaped design improves the uniformity and reliability of the sealing effect through the synergistic effect of multiple independent elastic members. Specifically, each fan-shaped elastic member can independently supply the protruding part to the pressing part, thereby ensuring uniform force on the seal at multiple points, effectively avoiding deformation or leakage of the seal due to local uneven force.

[0012] As a further optimization of the above scheme, an annular concave surface is opened on the upper side of the sealing part, and the second sealing member is embedded in the annular concave surface. One side of the second sealing member contacts the above flange and the other side contacts the sealing part. The second sealing member assists the sealing part of the first sealing member to seal the gap between the two flanges, thereby further improving the sealing effect of the flanges.

[0013] The Shakron interface for the biomass hot air furnace of the utility model has the following beneficial effects:

[0014] 1. The Shaklon interface for the biomass hot air furnace of the utility model realizes efficient production and reliable sealing of the equipment through modular design and optimized sealing structure, thereby greatly improving production efficiency, reducing maintenance costs, and ensuring the stability and safety of the equipment in long-term operation. Specifically, through the structure of the elastic part with the first sealing part, the elastic part provides uniform and sufficient extrusion force, which effectively compensates for the slight deformation of the first sealing part caused by temperature, pressure and other factors during use, ensures that the first sealing part and the flange always maintain a close fit, thereby achieving an excellent sealing effect.

[0015] 2. The utility model provides a new type of sealing structure by introducing two different designs of elastic parts, annular and fan-shaped. The annular design simplifies the installation process, while the fan-shaped design improves the uniformity and reliability of the sealing effect through the synergistic effect of multiple independent elastic parts. Specifically, each fan-shaped elastic part can independently supply the convex part to the pressed part, thereby ensuring uniform force on the seal at multiple points, effectively avoiding deformation or leakage of the seal due to uneven local force.

[0016] 3. The biomass hot air furnace of the utility model uses a Shakron interface, and the second sealing member assists the sealing part of the first sealing member to seal the gap between the two flanges, thereby further improving the sealing effect of the flanges.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Please refer to the instruction manual Figures 1-4 The utility model provides a first embodiment of a Shakron interface for a biomass hot blast stove, the Shakron interface comprises a main shell 1 and an auxiliary shell 2, and the Shakron connection port of the main shell 1 and the connection port of the auxiliary shell 2 are tightly connected through a connection assembly 3. The connection assembly 3 is mainly composed of two oppositely arranged flanges 31, and the two flanges 31 are pressed and fixed by bolts 32. This connection method allows fine adjustment during the assembly process to ensure accurate docking of the interface.

[0027] Specifically, a gap 33 is provided at the connection of the two flanges 31 for installing two oppositely arranged elastic members 4, one side of the elastic member 4 contacts the flange 31, and the middle holds the first sealing member 5. Through the squeezing effect of the elastic member 4, a tight sealing state is formed between the first sealing member 5 and the flange 31, effectively preventing the leakage of gas or particles.

[0028] In this embodiment, the elastic member 4 includes a pressing portion 41, a convex portion 42 and a plane portion 43 from outside to inside. The pressing portion 41 is arc-shaped, and its inner concave surface is tightly fitted to the outer circumferential surface of the first sealing member 5 and applies a uniform extrusion force thereto. One end of the convex portion 42 is connected to the pressing portion 41, and the other end is connected to the plane portion 43. The shape of the convex end matches the annular groove 311 provided on the flange 31, ensuring that the elastic member 4 can be stably installed on the flange 31. The plane portion 43 is arranged in parallel with the first sealing member 5, providing uniform support for the sealing member.

[0029] The first sealing member 5 is composed of a pressure-bearing portion 51 and a sealing portion 52. The pressure-bearing portion 51 is arc-shaped and arranged in cooperation with the pressing portion 41 of the elastic member 4. The double arc-shaped structure design ensures a good cooperation effect between the two and improves the sealing ability. The sealing portion 52 extends inwardly along the pressure-bearing portion 51, one side of which is in close contact with the flange 31, and the other side is in contact with the sealing portion 52 arranged oppositely, forming a complete sealing structure.

[0030] To further enhance the sealing effect, the bolt 32 of the present invention is designed to sequentially penetrate the flange 31, the compression portion 41 of the elastic member 4 and the compression portion 51 of the first sealing member 5 along the penetration path, making the entire connection structure more stable and the extrusion effect more significant.

[0031] As an optimization solution of the utility model, the elastic member 4 can be designed in an annular or fan-shaped manner. The annular design simplifies the installation process and improves the installation efficiency; while the fan-shaped design improves the uniformity and reliability of the sealing effect through the synergistic effect of multiple independent elastic members 4. Each fan-shaped elastic member 4 can independently supply extrusion force to the pressure-bearing part 51 of the first sealing member 5, thereby ensuring uniform force on the sealing member at multiple points, effectively avoiding deformation or leakage problems caused by uneven local force.

[0032] In addition, to further improve the sealing effect, an annular concave surface 6 is provided on the upper side of the sealing portion 52 of the first sealing member 5 for embedding the second sealing member 7. One side of the second sealing member 7 is in close contact with the flange 31, and the other side is in close contact with the sealing portion 52 of the first sealing member 5, forming a second sealing barrier, further improving the sealing performance of the interface.

[0033] The core of the above technical solution is to ensure the tight connection between the main housing 1 and the auxiliary housing 2 through the precisely designed connection assembly 3 and the sealing structure, so as to effectively prevent the leakage of gas or particles. The specific working principle is as follows:

[0034] Sealing mechanism of the connection assembly 3: The connection assembly 3 is composed of two oppositely arranged flanges 31 and bolts 32, and a gap is provided between the flanges 31 for installing the elastic member 4 and the first sealing member 5. The elastic member 4 is squeezed by the pressing action of the bolts 32, thereby forming a tight sealing state between the first sealing member 5 and the flange 31.

[0035] Function of elastic member 4: elastic member 4 provides extrusion force to ensure sealing, and its design also allows fine adjustment during assembly to adapt to slight deviations of the interface and ensure accurate docking. At the same time, its structural design ensures the stability of installation and improves the sealing effect.

[0036] Double sealing design: On the basis of the first sealing member 5, a second sealing member 7 is added to form a double sealing barrier, thereby further enhancing the sealing performance of the interface, enabling it to withstand higher gas pressures or better prevent particle leakage.

[0037] To sum up, by adopting the above technical scheme, the sealing performance of the Shaklon interface for the biomass hot air furnace of the utility model has been significantly improved, which effectively prevents the leakage of gas or particulate matter, ensures the stable operation of the biomass hot air furnace, and improves the use effect and safety of the equipment.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
