Door frame type sintering cake crushing equipment

Abstract

The invention relates to door frame type sintering cake crushing equipment, and belongs to the technical field of stepping sintering machine equipment. The door frame type sintering cake crushing equipment adopts the technical scheme that the door frame type sintering cake crushing equipment comprises a positioning machine (1), door frames (2), a hydraulic system (3), an ore discharging machine (4) and a crushing machine (5), wherein the door frames (2) include a movable door frame (6) and a stationary door frame (8), the stationary door frame (8) is connected with the movable door frame (6) by virtue of a lifting cylinder (11), groove-shaped trolley tracks (9) are arranged on both sides of the movable door frame (6), groove-shaped positioning tracks (10) are arranged on both sides of thestationary door frame (8), the positioning machine (1) is arranged on the groove-shaped positioning tracks (10), and the ore discharging machine (4) and the crushing machine (5) are respectively arranged on both sides of the door frames (2). The door frame type sintering cake crushing equipment has the beneficial effects that the ventilation negative pressure of an exhaust fan at a cooling sectionis reduced, so that the operating power of the exhaust fan at the cooling section is reduced, the operating power consumption of the cooling process is reduced by 60% approximately, and energy consumption is greatly reduced.

Description

[0002] The planar circulation stepping sintering machine is the main equipment for the sinter production of iron and steel enterprises. There are three sealing devices on the bellows table of the planar circulation stepping sintering machine: the head sealing plate, the middle sealing plate and the machine tail sealing plate. The sintering section is between the head sealing plate and the middle sealing plate, and the cooling section is between the middle sealing plate and the tail sealing plate. The sintering section and the cooling section are arranged in series on the same axis, and the sintering waste gas in the sintering section is treated with environmental protection. Finally, it is discharged by the exhaust fan in the sintering section, and the dusty exhaust gas in the cooling section is discharged by the exhaust fan in the cooling section after environmental protection treatment; The trolleys arranged in the axial direction move forward synchronously. At the tail of the sintering section, the sintered hot mineral cake with high density and physical structure strength after the sintering process leaves the intermediate seal and enters the cooling section for exhaust cooling. Due to the existence of hot mineral cake Larger density and physical strength Poor air permeability, greater air cooling resistance, higher air pressure required, higher operating power, resulting in a lot of waste of energy
