DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Embodiment 1, referring to Figures 1-4 , a full-hydrogen bell-type furnace platform support structure, including a cover plate 1, a diffuser 2 is fixed to the upper end of the cover plate 1, the cover plate 1 and the diffuser 2 are integrally formed, a support ring 15 is placed in the diffuser 2, and the support ring 15 is in a funnel shape;

[0022] A air supply mechanism is installed on the cover plate 1. The air supply mechanism includes a servo motor 9 installed on the lower end surface of the cover plate 1, and the output end of the servo motor 9 extends above the cover plate 1 and is installed with a wind leaf 4;

[0023] Ventilation holes 3 are equidistantly arranged on the cover plate 1. By driving the impeller 4 to rotate through the servo motor 9, cold air from the outside can enter the support ring 15 through the ventilation holes 3;

[0024] The bottom end of the cover plate 1 is connected with a U-shaped frame 5, and a buffer assembly is connected to the U-shaped frame 5. The buffer assembly includes strip holes 12 opened on both sides of the U-shaped frame 5. Fixed rods 14 are installed in both strip holes 12. L-shaped support rods 7 are slidably sleeved on both fixed rods 14. The horizontal sections of the two L-shaped support rods 7 are respectively slidably clamped with the two strip holes 12. Springs 13 are sleeved on both fixed rods 14 above the horizontal sections of the L-shaped support rods 7. The bottom ends of the vertical sections of the two L-shaped support rods 7 are connected with a bottom plate 8;

[0025] Through the elastic support function of the spring 13, the impact force generated by vibration can be buffered, reducing the probability of component damage;

[0026] Limit rods 11 are fixed on both sides of the upper end surface of the bottom plate 8. Limit holes 10 are opened at both ends of the horizontal section of the U-shaped frame 5. The two limit rods 11 respectively form a plug-in fit with the two limit holes 10;

[0027] The U-shaped frame 5 is limited by the two limit rods 11, effectively preventing the cover plate 1 from shaking;

[0028] Bolt support feet 6 are screwed to the bottom end of the bottom plate 8, and four bolt support feet 6 are installed. The four bolt support feet 6 are respectively located at the four corners of the lower end surface of the bottom plate 8. By turning the four bolt support feet 6, the bottom plate 8 can be adjusted to be stable, thus avoiding shaking.

[0029] Working principle: The diffuser 2 and the cover plate 1 are set as an integral fixed type to ensure interchangeability and universality with on-site processes and equipment. Solve problems such as deformation of the original furnace platform cover plate, deformation and inclination of the support columns, cracking of the connecting plates, misalignment of the diffuser, jamming and damage of the motor impeller, and oxidation of the steel coil. By driving the impeller 4 to rotate through the servo motor 9, cold air from the outside can enter the support ring 15 through the ventilation holes 3. Through the elastic support function of the spring 13, the impact force generated by vibration can be buffered, reducing the probability of component damage;

[0030] Through nearly two months of effect observation, the improvement of this device has changed problems such as deformation of the original furnace platform cover plate, misalignment of the diffuser, jamming and damage of the motor impeller, and oxidation of the steel coil, and the operation effect is very good.

[0031] Description of the project's efficiency creation overview:

[0032] 1. Economic benefits: 1. Improve the operation rate of the furnace platform, which can reduce the failure time by 160 * 5 = 800 h / month. The production capacity of a single furnace platform is 1.82 tons / h, the profit per ton of steel is 500 yuan / ton, and the contribution coefficient of the heat treatment process is 0.2. The annual increased profit can be: 1.82 x 160 x 5 x 12 x 500 x 0.2 = 1.747 million yuan.

[0033] 2. Savings in maintenance costs

[0034] By comparing with and without the project, the annual maintenance cost savings per furnace can be 240,000 yuan. The total annual maintenance cost savings for 5 furnaces is 1.2 million yuan. After the major overhaul, the spare parts cost and maintenance cost are saved by 20 + 4 * 5 = 1.2 million yuan.

[0035] In total, the economic benefits of 5 furnace platforms can be increased by 1.747 + 1.2 = 2.947 million yuan.
