DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 , a boiler economizer support structure, comprising a bottom block 1, an economizer body 2 is arranged outside the bottom block 1, and a shock-absorbing support device 3 is arranged outside the bottom block 1;

[0021] The shock-absorbing support device 3 includes a bidirectional threaded rod 301, a motor 302, a sliding rod 303, a mounting block 304, a shock-absorbing rubber 305, a spring damper 306, a support frame 307, a filter plate 308, an auxiliary rod 309 and an electric slide rail 310. The bidirectional threaded rod 301 is arranged inside the bottom block 1, the motor 302 is arranged inside the bottom block 1, the sliding rod 303 is arranged inside the bottom block 1, the outer surface of the bidirectional threaded rod 301 is threadedly connected with the mounting block 304, the inner bottom wall of the mounting block 304 is fixedly installed with a shock-absorbing rubber 305, the spring damper 306 is arranged inside the mounting block 304, the outside of the mounting block 304 is arranged with a support frame 307, the bottom of the economizer body 2 is provided with a filter plate 308, the auxiliary rod 309 is fixedly installed inside the support frame 307, and the electric slide rail 310 is fixedly installed inside the support frame 307.

[0022] Specifically, Figure 2 As shown, the purpose of setting the filter plate 308 is to filter the flue gas before it exchanges heat from bottom to top in the economizer body 2 during use, so as to prevent the particulate matter in the flue gas from damaging the economizer body 2, and at the same time appropriately reduce the impact force of the flue gas on the economizer body 2.

[0023] Specifically, Figure 2As shown, during use, the economizer body 2 will generate vibrations, and these vibrations will be transmitted to the U-shaped plug through the support frame 307. After encountering the vibration, the U-shaped plug will move downward with the two support frames 307 and the economizer body 2, and squeeze the spring damper 306 on the second mounting plate, thereby squeezing the first mounting plate and the shock-absorbing rubber 305. The purpose of shock-absorbing the equipment is achieved through the cooperation of the shock-absorbing rubber 305 and the spring damper 306.

[0024] Specifically, Figure 2 As shown, the material of the spring damper 306 is made of high damping spring shock absorber. The springs are treated with heat treatment, ED anti-rust, paint and other procedures. The seismic grade has excellent pressure resistance, and has simple structure, convenient assembly, corrosion resistance, acid and alkali resistance, and high temperature resistance. The shock-absorbing rubber 305 is also called rubber shock-absorbing product, which is mainly used to eliminate or reduce the transmission of mechanical vibration to achieve the purpose of shock absorption, silencing and reducing the harm caused by impact. This material has excellent high elasticity and viscoelasticity, and can effectively absorb and disperse the vibration energy generated by the source, especially in preventing the synchronous vibration caused by the resonance effect generated by the vibration wave.

[0025] When implementing, follow these steps:

[0026] 1) First, turn on the motor 302 to drive the bidirectional threaded rod 301 to rotate, thereby driving the two mounting blocks 304 to move;

[0027] 2) Then, a suitable support frame 307 is plugged in through the plug-in block and the U-shaped plug-in block, and fixed by bolts;

[0028] 3) Place the economizer body 2 inside the two support frames 307 and fix it by means of the electric slide rail 310 and the pressing plate;

[0029] 4) Finally, the spring damper 306 and the shock-absorbing rubber 305 are used to provide shock-absorbing treatment to the device when it is in use.

[0030] To summarize, the boiler economizer support structure, when the motor 302 is turned on, drives the bidirectional threaded rod 301 to rotate, thereby driving the two mounting blocks 304 to move. After moving to a position suitable for the economizer body 2, a support frame 307 of a suitable size for the economizer body 2 is plugged in through the plug-in block and the U-shaped plug-in block, and fixed by bolts. The economizer body 2 is then placed inside the two support frames 307. The electric slide rail 310 is then turned on to drive the pressing plate to move downward along the auxiliary rod 309 to fix the economizer body 2. The shock-absorbing rubber 305 and the spring damper 306 are then used to dampen the device during use, thereby achieving the purpose of supporting and fixing economizer bodies 2 of different sizes while damping them.
