Description

Technical Field

[0001] The utility model relates to the technical field of sintered mesh processing, in particular to an anti-vibration device for a sintering furnace of a high-strength pressure-resistant sintered mesh. Background Art

[0002] Sintered mesh is a special filtering material, which is formed by heating and sintering tiny particles (such as metals, plastics, etc.) and has a mesh structure with many small holes. This mesh structure enables the sintered mesh to be used to filter various fluids, such as liquids and gases, to remove impurities, particles, pollutants, etc. therein, so as to achieve the purpose of purifying the fluid. The sintered mesh has high mechanical strength and wear resistance, can withstand large frictional forces and pressures, and ensures the stable operation of the filtering equipment. During the processing of the sintered mesh, it needs to be processed through a sintering furnace.

[0003] For example, the patent application number disclosed by the Chinese Patent Network is: 201220205165.9, and the patent name is: Wire Mesh Sintering Furnace, which includes a furnace body composed of a furnace wall and a furnace chamber. A hydraulic mechanism is arranged above the furnace body. A first through hole is opened on the furnace wall. A second through hole is opened at a position corresponding to the first through hole above the sintering chamber. The hydraulic jack of the hydraulic mechanism passes through the first through hole and the second through hole. The hydraulic jack includes a heat-resistant jack at the top and a metal support rod behind the heat-resistant jack. While sintering, the pressure between the mesh sheets in the sintered mesh network is increased, so that it is formed in one sintering. Compared with the existing process of using sintering, cold rolling, re-sintering or multiple cycles, the energy consumption is reduced, thus reducing the production cost; not only saving the isolation layer, reducing the cleaning process, and improving the work efficiency; but also reducing the occurrence of problems that damage the stainless steel material, making the filtering accuracy of the sintered mesh more uniform.

[0004] However, the structure of the existing sintering furnace is relatively simple. The sintered mesh is mainly connected to the sintering furnace in a plug-in manner. During the operation of the sintering furnace, a high-strength circulating air flow will be generated inside. When the plug-in sintered mesh contacts the air flow, it will generate impact vibration, resulting in the phenomenon that tiny particles on the surface of the sintered mesh fall off.

[0005] Therefore, it is necessary to design and transform an anti-vibration device for a sintering furnace of a high-strength pressure-resistant sintered mesh. Content of the Utility Model

The adjustment structure can drive the linkage plate to vertically lift and lower.

[0011] Preferably, the adjustment structure includes a connecting frame communicated with the bottom of the inner wall of the furnace body.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1 to 4 shown, a sintering furnace anti-vibration device for a high-strength pressure-resistant sintering mesh provided by the present utility model includes a furnace body 1 capable of forming a vacuum state inside;

[0030] Guide rails 2 fixedly connected to both sides of the inner wall of the furnace body 1;

[0031] A sintering mesh frame 3 inserted inside the furnace body 1 and located inside the guide rails 2;

[0032] Positioning structures 4 are provided on both sides of the inner wall of the furnace body 1. The positioning structure 4 includes connecting blocks 5 fixedly connected to both sides of the inner wall of the furnace body 1. A pressing plate 6 is movably connected to the surface of the connecting block 5 through a pin shaft. One side of the pressing plate 6 away from the connecting block 5 contacts the bottom of the sintering mesh frame 3. A stress rod 7 is fixedly connected to one side of the pressing plate 6 close to the connecting block 5. A linkage plate 9 is installed at the bottom of the inner wall of the furnace body 1 through an adjusting structure 8. Pressing rods 10 are fixedly connected to both ends of the linkage plate 9. One side of the pressing rod 10 away from the linkage plate 9 extends to the bottom of the stress rod 7. The outer surface of the pressing rod 10 contacts the surface of the stress rod 7. The adjusting structure 8 can drive the linkage plate 9 to vertically lift and lower.

[0033] Referring to Figure 3 , the adjusting structure 8 includes a connecting frame 11 communicated with the bottom of the inner wall of the furnace body 1. A metal corrugated cover 12 is communicated with the top of the connecting frame 11. The metal corrugated cover 12 can be folded and contracted. The top of the metal corrugated cover 12 is fixedly connected to the bottom of the linkage plate 9.

[0034] As a technical optimization scheme of the utility model, by adopting a combination of a metal corrugated cover 12 and a linkage plate 9, the stretching characteristics of the metal corrugated cover 12 in a vacuum state are utilized to automatically drive the linkage plate 9 to rise and fall without the need for an external power source, thereby achieving automatic adjustment, simplifying the equipment structure, and reducing energy consumption and costs.

[0035] refer to Figure 4 Support plates 13 are fixedly connected to both sides of the inner wall of the metal corrugated cover 12. The side of the support plate 13 away from the metal corrugated cover 12 penetrates the connecting frame 11 and extends to the bottom of the connecting frame 11. The support plate 13 is slidably connected to the connecting frame 11.

[0036] As a technical optimization solution of the utility model, by setting the support plate 13, not only additional support is provided for the metal corrugated cover 12 to prevent it from deformation or damage during the extension process, but also through the sliding connection with the connecting frame 11, the stability of the metal corrugated cover 12 during the extension and contraction process is ensured, thereby further improving the reliability and service life of the equipment.

[0037] refer to Figure 4 The top of the linkage plate 9 is fixedly connected with an elastic frame 14, and the side of the elastic frame 14 away from the linkage plate 9 is in contact with the bottom of the sintering mesh frame 3, and the elastic frame 14 is elastic.

[0038] As a technical optimization solution of the utility model, the elastic frame 14 fixed on the top of the linkage plate 9 contacts the bottom of the sintering mesh frame 3, providing additional support and buffering for the sintering mesh frame 3. During the sintering process, the elastic frame 14 can absorb part of the vibration energy, reduce the shaking of the sintering mesh frame 3, and protect the sintering mesh frame 3 from damage.

[0039] refer to Figure 4 The bottom of the pressing plate 6 is fixedly connected with a reinforcing rib 15, and the side of the reinforcing rib 15 away from the pressing plate 6 is fixedly connected to the surface of the force-bearing plate.

[0040] As a technical optimization solution of the utility model, the reinforcing ribs 15 fixed at the bottom of the pressing plate 6 are connected to the surface of the force-bearing plate, thereby enhancing the strength and rigidity of the pressing plate 6, making it less likely to deform when the pressing plate 6 is under pressure, and being able to more effectively transfer the pressure to the sintering mesh frame 3 to maintain its stability.

[0041] refer to Figure 4 Guide rods 16 are fixedly connected to both sides of the bottom of the inner wall of the furnace body 1. The side of the guide rod 16 away from the furnace body 1 passes through the linkage plate 9 and extends to the top of the linkage plate 9. The linkage plate 9 is slidably connected to the guide rod 16.

[0042] As a technical optimization solution of the present utility model, the guide rod 16 fixed at the bottom of the inner wall of the furnace body 1 passes through the linkage plate 9 and is slidably connected thereto, restricting the moving direction of the linkage plate 9 to ensure that it can only move vertically, improving the accuracy and stability of the lifting of the linkage plate 9, and preventing equipment failures and damage to the sintering mesh frame 3 caused by deviation or inclination.

[0043] The working principle and usage process of the present utility model: The sintering mesh frame 3 is inserted into the inner side of the guide rail 2 inside the furnace body 1 and is located at an appropriate position. When the installation of the sintering mesh frame 3 is completed, the user closes the furnace body 1, and a vacuum state is formed inside the furnace body 1 of the sintering furnace, preparing for the sintering process. Due to the pressure difference between the inside and outside of the furnace body 1, the metal corrugated cover 12 begins to stretch upward, driving the linkage plate 9 to rise vertically. During the rising process of the linkage plate 9, the pressure rods 10 at both ends thereof gradually come into contact with and press the stress rods 7, and the stress rods 7 then transfer the pressure to the pressing plate 6. As the linkage plate 9 continues to rise, the pressing plate 6 gradually presses the bottom of the sintering mesh frame 3 under the action of the stress rods 7. The reinforcing ribs 15 at the bottom of the pressing plate 6 increase the rigidity and stability of the pressing plate 6, ensuring that the sintering mesh frame 3 is firmly fixed. At the same time, the elastic frame 14 also comes into contact with the bottom of the sintering mesh frame 3 as the linkage plate 9 rises, providing additional support and buffering. Under the pressing action of the pressing plate 6, the sintering mesh frame 3 remains stable inside the furnace body 1, reducing the jitter caused by temperature changes or air flow disturbances. When the sintering process is completed, the temperature of the furnace body 1 gradually decreases, the vacuum state is released, and the metal corrugated cover 12 gradually contracts back to its original position after losing the external pressure, driving the linkage plate 9 to descend.

[0044] In summary: The anti-jitter device for the sintering furnace of the high-strength pressure-resistant sintering mesh effectively prevents the movement and jitter of the sintering mesh frame 3 during the sintering process by arranging the positioning structure 4 on both sides of the inner wall of the furnace body 1 and using the contact between the pressing plate 6 and the bottom of the sintering mesh frame 3, improving the stability of the sintering process and ensuring the quality of the sintered mesh products.
