Description
Technical Field
[0001] The utility model relates to the technical field of smoke purification, in particular to a smoke purification device for rail grinding and rust removal. Background Art
[0002] During the grinding process of long rail welding joints, a large amount of fine metal particles and a small amount of mixed gas will be generated. If they are not fully treated and allowed to diffuse in the air, workers who have been engaged in this operation for a long time will inhale them, which will have adverse effects on their health and even cause occupational diseases such as pneumoconiosis, which will damage the health of workers. Therefore, strengthening the fume purification of rail welding joint grinding is an important task to protect the health of workers.
[0003] The splashing particles generated by grinding rails with grinding wheels are mainly aluminum oxide particles and a small amount of metal mixed gas from the burning of iron, carbon, silicon, manganese, phosphorus, sulfur and other oxides by high-temperature sparks. People who have been engaged in grinding operations for a long time will inhale harmful gases containing metal particles into their bodies, which will harm their lungs and easily form silicosis, seriously affecting their lives and health. Therefore, it is necessary to collect and treat the generated metal particles and harmful mixed gases to avoid diffusion in the surrounding air, keep the workshop air clean, and minimize the inhalation of harmful gases by operators. With the development of society, purification devices are used when smoke purification is required during the grinding and rust removal process of rails.
[0004] When workers use the purification device, the purification device will suck harmful smoke into the pipe through the dust suppression hood. The pipe will guide the smoke into the purifier so that the purifier can purify the smoke. However, the purification device requires huge power support in the process of absorbing the smoke, causing the noise generated inside the purifier to be transmitted to the dust suppression hood through the pipe, thereby causing the noise generated by the purifier during use to be exposed outside the equipment.
[0005] Embodiment 1: By setting up a noise reduction device, the worker places the first baffle and the second baffle on the dust suppression hood in turn, and the plug plates at the bottom ends of the first baffle and the second baffle will be inserted into the positioning block. When the top plate at the top end of the second baffle contacts the surface of the top end of the first baffle, the support bar contacts the surface of the storage sleeve. The worker rotates the positioning rod, and the positioning rod is inserted into the threaded mouth and threadedly connected. When noise is transmitted from the dust suppression hood, the first baffle and the second baffle will block the noise.
[0006] Embodiment 2: By setting up a replacement device, the worker pulls the insertion rod, the insertion rod slides and detaches from the dust suppression cover, the worker pulls the damaged dust shield frame, the damaged dust shield frame drives the placement block, the placement block detaches from the card block, when the placement block detaches from the card block, the worker replaces the damaged dust shield frame.
