DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0017] Please refer to Figures 1-5This utility model provides a water-cooled dust removal device for high-temperature dust in a medium-frequency melting furnace, including a dust removal box 1. A dust removal hood 2 is provided on one side of the dust removal box 1, and an induced draft fan 3 is provided on the other side of the dust removal box 1. A filter cover 4 is provided inside the dust removal box 1 at a position corresponding to the induced draft fan 3. Wind baffles 5 are arranged vertically and vertically inside the dust removal box 1. A water-cooling chamber 6 is provided inside the wind baffles 5. A water inlet pipe 7 is connected to the lower front end of the dust removal box 1 and the water-cooling chamber 6. A water outlet pipe 8 is connected to the upper rear end of the dust removal box 1 and the water-cooling chamber 6. An air guide plate 9 is provided inside the dust removal box 1 and between two adjacent wind baffles 5. A dust removal chamber door 10 is provided at the lower rear side wall of the dust removal box 1.
[0018] During operation, the induced draft fan 3 is turned on, drawing the dust generated by the medium-frequency melting furnace into the dust collector 1 through the dust collector hood 2. A filter hood 4 is installed inside the dust collector 1 at a position corresponding to the induced draft fan 3. The filter hood 4 filters the dust inside the dust collector 1, preventing it from being discharged outside the dust collector 1 by the induced draft fan 3. Wind baffles 5 are installed inside the dust collector 1, with the baffles arranged in a staggered pattern to allow the dust to circulate back and forth within the dust collector 1. The deflection of airflow reduces the velocity of the dust, causing it to fall into the dust collector 1. Air guides 9 are installed between the baffles 5 to direct the airflow. A water-cooled chamber 6 is located inside the baffles 5, and cooling water is supplied to the chamber 6 via the inlet pipe 7. As the airflow passes through the baffles 5, the temperature of the dust and airflow is reduced. The cooling water, having completed heat exchange, is then discharged through the outlet pipe 8. When a significant amount of dust accumulates inside the dust collector 1, the dust collection chamber door 10 is opened to process the dust.
[0019] The dust collector 1 is provided with an air outlet 11 on the side near the induced draft fan 3. The induced draft fan 3 is connected to the dust collector 1 through the air outlet 11. The filter cover 4 is connected to the air outlet 11 through a connecting flange. The filter cover 4 is placed inside the dust collector 1 while connecting the induced draft fan 3 to the dust collector 1 through the discharge pipe 11.
[0020] The front and rear sides of the windbreak 5 are provided with water-cooled pipe ports 12 that penetrate the dust collection box 1. The water inlet pipe 7 and the water outlet pipe 8 are respectively connected to the water-cooled pipe ports 12 through pipes. By setting the water-cooled pipe ports 12, which penetrate the dust collection box 1, the water inlet pipe 7 and the water outlet pipe 8 are respectively connected to the front and rear sides of the windbreak 5.
[0021] The dust collection box 1 is provided with an air inlet 13 on the side near the dust collection hood 2. An air inlet pipe 14 is connected between the air inlet 13 and the dust collection hood 2. The dust collection hood 2 and the dust collection box 1 are connected through the air inlet 13 and the air inlet pipe 14.
[0022] The two adjacent air guide plates 9 are arranged at a perpendicular angle to each other, and the air guide plate 9 is arranged at a 45° angle to the windbreak plate 5. The airflow is guided by the specific structure of the air guide plate 9.
