Induction melting furnace is an important equipment in the foundry industry. Induction melting furnace has the advantages of fast heating speed and high production efficiency. At the same time, the perfect dust removal system of the induction melting furnace is also one of its highlights. So what are the dust removal systems of the induction melting furnace? Today I will take everyone to understand in detail.
1. Dust removal inlet system of melting furnace
The air intake system includes air inlets, inlet throttles, wind deflectors, air deflectors, distribution screens, etc. Dust-containing air flows into each bag room through the conveying pipe, the wind speed is reduced, and most of the dust directly falls into the ash hopper, reducing the filter bag. The dust that has not been collected together with the flue gas passes through the air deflector through the distribution screen and enters the bag chamber, filling the entire space. The wind deflector and the distribution screen ensure that the dust-containing air flow and the dust-cleaning air flow are upwardly flowing in the direction of the filter bag . If the owner requires the equipment to be manufactured in-line cleaning, this airflow movement direction can greatly reduce the secondary fly ash during cleaning.
2.Smelting furnace dust removal and ash filtering system
Including filter bags, bag cages, flower plates, etc., each filter bag is sleeved on a bag cage, in order to prevent the cloth bag from being crushed. The flower plate is used to support the filter bag assembly and separate the bag room and the air purifying room, and serve as Maintenance platform for dust filter system components.
3.Induction melting furnace dust removal and dust removal system 炉
Including clean air pipe, compressed air pipe, pulse valve, poppet valve, venturi, etc., the clean air pipe is arranged in parallel in the pre-assembled top clean air chamber, each of which has a number of small air nozzles, these small air nozzles One for each Venturi tube on each filter bag. The clean air pipe is connected to the external compressed air pipe. The beginning of the pipe is inserted into the card slot, and the end is welded to the supporting angle steel and positioned with the pipe card. A compressed air pipe is installed on the top of the dust collector, and the pipe is connected to the air cleaner pipe. Compressed air is controlled by a pulse valve. The pulse valve is connected to a solenoid valve. The operation of the entire dust cleaning system is uniformly controlled by the control system of the dust collector. The sensors that detect the differential pressure at both ends of the dust collector are fixed at the outlet and inlet of the air pipe, and control the dust removal cycle of the dust collector according to the differential pressure signal detected by the differential pressure meter.
4. Induction melting furnace dust removal exhaust system
Dust collector purification gas discharge system including outlet throttle valve, exhaust pipe, etc.
5. Dust removal system for induction melting furnace
The dust removal of the precipitator adopts a single-point ash discharge mode with a closed scraper conveyor + double spiral humidifier. The ash discharge equipment includes: 8 star-shaped ash discharge valves, 2 first-level scraper conveyors, and 1 humidifier. When unloading the ash, the star-shaped ash unloading valve, the first-level scraper conveyor, the first-level scraper conveyor, and the humidifier can be sequentially opened, and multiple ash buckets cannot be unloaded at the same time.
6. Induction melting furnace dust removal control system
The electrical control part is the command center of the entire dust removal system. The reliability of the control part will directly affect the normal operation of the dust removal system. Therefore, the electrical control system should meet the process requirements, operate stably and reliably, be safe and economical, simple to operate, and easy to maintain.
