Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, specifically to a temperature-controlled carbon powder dust removal device. Background Technology
[0002] Currently, in hydro-generator units, the collector ring chamber is typically open-styled, with most protective covers consisting of mesh grilles. The openings are too large to create an effective airflow, rendering the carbon dust recovery device ineffective and failing to collect dust. During unit operation, carbon brush wear, combined with fan effects and inadequate sealing of the baffles, causes carbon dust to fly around. This, along with oil mist from leaking oil receivers, leads to carbon dust adhering to the rotor collector rings, busbars, brush holders, and excitation wires. This results in frequent rotor single-point grounding faults and severe contamination of the stator bars and other equipment within the generator head, directly jeopardizing the safe and stable operation of the unit.
[0003] To address this issue, various toner dust collection solutions exist on the market, such as dual-airflow toner dust collection devices and simple toner dust collection devices. However, these products suffer from key defects such as low dust collection efficiency and short service life. Furthermore, they cause the temperature of the collector ring chamber to increase during use, posing safety hazards during operation. Moreover, disassembly and maintenance during maintenance require significant manpower and time, impacting the power plant's time costs.
[0004] Therefore, it is necessary to develop a temperature-controlled carbon dust removal device to solve the above problems. Utility Model Content

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] Please see Figures 1-2 This utility model provides a temperature-controlled carbon powder dust removal device, comprising: a main shaft 1, a slip ring 2, a stainless steel dust cover 3, a temperature-regulating breather 4, a first ventilation duct 5, a second ventilation duct 6, a temperature detection module 7, an air supply module 8, a dust collection module 9, a dust collection auxiliary module 10, an electrical system module 11, a dust storage module 12, an openable observation window 13, an alarm 14, and a dust-proof brush 15; the dust-proof brush 15 is disposed on the outside of the main shaft 1, and N temperature-regulating breathers 4 are disposed on the slip ring 2, with the temperature detection module 7 disposed on the outside of the N temperature-regulating breathers 4. A stainless steel dust cover 3 is positioned above the collector ring 2; the stainless steel dust cover 3 has N openable observation windows 13; one end of the first ventilation duct 5 is connected to the stainless steel dust cover 3 via a socket joint, and the opposite end is connected to the auxiliary dust collection module 9 via a socket joint; the auxiliary dust collection module 10 and the dust collection module 9 are integrated; one end of the second ventilation duct 6 is connected to the stainless steel dust cover 3 via a socket joint, and the opposite end is connected to the air supply module 8 via a socket joint; the air supply module 8 and the electrical system module 11 are integrated; an alarm 14 is installed at the top of the electrical system module 11.
[0025] Specifically, both the first ventilation duct 5 and the second ventilation duct 6 use stainless steel flexible hoses.
[0026] Specifically, the dust-proof brush 15 and the main shaft 1 are sealed by motion.
[0027] Working Principle: When the unit is running, the temperature-controlled toner dust collector shown in this application automatically connects to the power supply. Under the control of the electrical system module 11, the dust collection module 9 starts working, allowing the low-temperature air outside the stainless steel dust cover 3 to enter the collector ring 2 position through the temperature regulating breather 4 and suck out the dust generated during unit operation. The dust collection auxiliary module 10 is in standby mode, and the air is filtered through the dust collection bag. At the same time, the air supply module 8 starts working, supplying air to the collector ring 2 position. When the temperature-controlled toner dust collector is connected to the power supply, the temperature detection module 7 immediately starts and is in real-time detection mode. When the detected temperature is higher than the set value, a signal is transmitted and the alarm 14 is activated. At the same time, the dust collection auxiliary module 10 starts working, increasing the internal and external airflow, improving the heat dissipation effect, and controlling the temperature within the set value, ensuring that the collector ring 2 position is dust-free and the temperature is controllable for safe operation.
[0028] To ensure unobstructed airflow and facilitate operation and maintenance, both the first and second ventilation ducts 6 are made of stainless steel flexible hoses. The pipe connections are fastened with threads. The dust collection ducts are heat-resistant, have good sealing properties, and are flexible, safe, and reliable to install. The dust-proof brush 15 is sealed to the main shaft 1 to improve the sealing effect of the collector ring 2 chamber and enhance the dust collection function.
[0029] To facilitate routine observation and maintenance of the unit, an openable observation window 13 is installed at the position of the stainless steel dust cover 3. During operation and maintenance, some maintenance work on the slip ring 2 can be carried out through the openable observation window 13 without disassembling the stainless steel dust cover 3.
[0030] All key components of the temperature-controlled carbon dust removal device (temperature detection module 7, air supply module 8, dust collection module 9, dust collection auxiliary module 10, electrical system module 11, dust storage module 12) are modularly designed, making inspection and maintenance extremely convenient, installation and replacement easy, and saving time and costs for power plant inspection and maintenance.
[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
