The lower end of the cathode suspension rod is connected to the cathode of the electric dust collector to be supported, and the upper end of the cathode suspension rod passes through the insulating porcelain bottle, the support piece, and the anti-collapse suspension bracket in sequence before being sleeved with a fixed nut. The bottom of the anti-collapse suspension bracket is fixed with an insulating porcelain column, and a spring is arranged below the insulating porcelain column. This support structure can prevent the collapse of the cathode system of the electric dust collector. However, there are still the following problems. The components composed of the convex-concave gasket, the fixed nut, the cathode suspension rod, the support piece, and the insulating porcelain bottle in the utility model do not have a buffering structure themselves, and only rely on the simple buffering of the spring, the insulating porcelain column, and the anti-collapse suspension bracket. In the event of an accident, the components composed of the convex-concave gasket, the fixed nut, the cathode suspension rod, the support piece, and the insulating porcelain bottle are prone to damage. In addition, the components composed of the convex-concave gasket, the fixed nut, the cathode suspension rod, the support piece, and the insulating porcelain bottle also have the problems of poor sealing, poor high-temperature resistance, etc. SUMMARY

[0018] The utility model will be further described in combination with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and can be implemented, but the embodiments are not as the limitation of the utility model.

[0019] EMBODIMENT

[0020] An electric precipitator hanging anti-collapse device, such as Figures 1-2As shown, including the electric precipitator shell 1, two support porcelain columns 2 symmetrically fixed above the electric precipitator shell 1, an anti-collapse suspension frame 3 fixedly installed above the two support porcelain columns 2, and a cathode hanging component 4 installed through the anti-collapse suspension frame 3.

[0021] The cathode hanging component 4 comprises a cathode hanging support channel steel 41 welded with the electric precipitator shell 1, a bottom disc assembly 42 supported through the cathode hanging support channel steel 41, a protection sleeve 43 welded below the bottom disc assembly 42, an insulating sleeve 44 fixedly installed above the bottom disc assembly 42 and coaxial with the protection sleeve 43, a tubular heater 45 installed around the insulating sleeve 44, an upper disc assembly 46 fixed above the insulating sleeve 44, a hanging steel pipe 47 penetrating through the upper disc assembly 46 and then through the insulating sleeve 44, the bottom disc assembly 42 and the protection sleeve 43 in sequence, a gland 48 sleeved on the upper end of the hanging steel pipe 47 and embedded in the upper disc assembly 46, and a compression nut 49 screwed on the upper end of the hanging steel pipe 47 and compressing the gland 48.

[0022] It should be further explained that the core anti-collapse structure of the utility model adopts two support porcelain columns 2 cooperating with the anti-collapse suspension frame 3 to form a primary bearing system, and the cathode hanging component 4 forms a secondary buffer system.

[0023] The bottom disc assembly 42 comprises an annular bottom disc 421, a steel ring pad 422 welded at the bottom of the annular bottom disc 421 and in contact with the cathode hanging support channel steel 41, a bottom disc steel sleeve 423 welded above the annular bottom disc 421, a lower base plate 424 abutting above the annular bottom disc 421 and used for contacting the insulating sleeve 44, and a bottom disc water glass sealing body 425 filled between the insulating sleeve 44 and the bottom disc steel sleeve 423.

[0024] The annular bottom disc 421 and the steel ring pad 422 adopt a stepped stacking structure, and the bottom disc steel sleeve 423 and the annular bottom disc 421 form a concentric cylinder through vertical welding, specifically, the bottom disc steel sleeve 423 and the annular bottom disc 421 can ensure vertical stress.

[0025] Specifically, the annular bottom disc 421, the steel ring pad 422 and the bottom disc steel sleeve 423 jointly act to effectively disperse and uniformly transmit the external applied load, which helps to reduce excessive local pressure and prevent local structure from being damaged due to excessive load bearing, and the bottom disc steel sleeve 423 and the annular bottom disc 421 are fixed through vertical welding to ensure the rigidity and stability of the structure. This design enhances the bearing capacity of the system, so that the entire cathode hanging component 4 can better withstand vibration and external force during work.

[0026] The lower cushion plate 424 is in close contact with the insulating sleeve 44, providing additional protection against wear and tear of the insulating sleeve during operation. The bottom disc water glass seal 425 filled between the insulating sleeve 44 and the bottom disc steel sleeve 423 effectively increases the sealing of the system, preventing the leakage of internal dust or gas, while also providing protection for the insulating sleeve, avoiding direct damage from high temperature, high voltage, high dust and other environments. The bottom disc water glass seal 425 has good high temperature resistance and corrosion resistance, and can maintain its sealing effect in a high temperature working environment, ensuring the long-term stable operation of the system, avoiding the common failure of sealing materials due to high temperature or contact with corrosive substances.

[0027] Most importantly, the bottom disc assembly has a certain buffering effect, the insulating sleeve 44 is supported by the lower cushion plate 424 and fixed by the bottom disc water glass seal 425, which can effectively reduce the impact of vibration and impact on the equipment, improve the overall anti-seismic ability, and prolong the service life of the equipment.

[0028] The tubular heater 45 is close to the bottom disc assembly 42. Specifically, when the tubular heater 45 is powered and heated, it can avoid the formation of a conductive water film on the surface of the insulating sleeve 44 due to condensation, prevent high-voltage creepage short circuit, and eliminate thermal stress cracks in the insulating sleeve 44 caused by sudden temperature changes.

[0029] The upper disc assembly 46 includes an annular upper disc 461, an upper disc outer steel sleeve 462 welded to the outside of the annular upper disc 461, an upper cushion plate 463 attached to the bottom of the annular upper disc 461, an upper disc water glass seal 464 filled between the insulating sleeve 44 and the upper disc outer steel sleeve 462, a steel pipe sheath 465 welded to the inside of the annular upper disc 461 below, and a glass fiber rope 466 filled inside the steel pipe sheath 465 and tightly hanging around the steel pipe 47.

[0030] Specifically, the upper disc water glass seal 464 is filled between the insulating sleeve 44 and the upper disc outer steel sleeve 462, enhancing the sealing, effectively preventing gas leakage and internal dust from entering, ensuring the sealing performance of the system in a high temperature working environment, thereby improving the safety and stability of the equipment, and the annular upper disc 461 and the upper disc outer steel sleeve 462 are welded to improve the rigidity of the entire assembly, enhance its ability to withstand external loads, prevent structural deformation due to external forces or vibration, and maintain the stability of the system during operation.

[0031] It needs to be further explained that the glass fiber rope 466 filled inside the steel pipe sheath 465 forms a sealing protective layer. By densely filling the glass fiber rope and under the pressure of the compression nut 49 applied to the compression gland 48, the glass fiber rope not only achieves good sealing effect, but also plays the good high temperature resistance performance of the glass fiber rope, which can effectively isolate the leakage of gas and dust and provide additional protection. This design has special significance in high temperature or high voltage, high dust environment.

[0032] Most importantly, the combination of the steel pipe sheath 465 and the glass fiber rope 466 not only provides sealing protection, but also provides a certain buffering effect to the upper disc assembly, reduces the impact of vibration or impact suffered by the equipment during use, and improves the shock resistance and reliability of the equipment.

[0033] The hanging steel pipe 47 is a steel pipe with threads at both ends.

[0034] The anti-loose nut 471 and the end sealing nut 472 are rotatably installed on the upper end of the hanging steel pipe 47, the quartz sleeve 473 is sleeved on the middle section of the hanging steel pipe 47, and the support nut 474 for supporting the quartz sleeve 473 is rotatably installed on the lower end of the hanging steel pipe 47.

[0035] The design of the anti-loose nut 471 can effectively prevent the hanging steel pipe 47 from loosening or falling off due to vibration or external force during use, thereby improving the safety and reliability of the system, and the end sealing nut 472 is rotatably installed on the upper end of the hanging steel pipe 47, which provides good sealing effect and prevents external substances from entering the inside of the hanging steel pipe, while enhancing the sealing performance, avoiding gas leakage, and ensuring the sealing performance of the system in high temperature or special working environment.

[0036] The above embodiments of the utility model are not a limitation on the protection scope of the utility model, and the implementation manner of the utility model is not limited to this. According to the above content of the utility model, according to the ordinary technical knowledge and conventional means in the art, other various forms of modification, replacement or change of the above structure of the utility model are made without departing from the above basic technical idea of the utility model, and all should fall within the protection scope of the utility model.
