Embodiment Construction

[0022] Figure 1 ~ Figure 2 It is a specific embodiment of the present invention.

[0023] 1. Mechanical part

[0024] Unloading trolley: The device for transporting the ash accumulated in the air box of the ring cooler is a cuboid iron box whose size can be designed and processed according to the amount of ash. The upper opening is the ash inlet, and four wheels are installed below. In order to ensure that the trolley runs normally along the track driven by the motor, safety facilities are added to each rotating part of the trolley.

[0025] Trolley track: ring-shaped, used for walking and positioning of the ring-cooled trolley. The worm valve is used to unload ash, and the electric lever of the motor drives the worm valve to unload ash, and it has a remote ash unloading control circuit.

[0026] Safety facilities: In order to ensure the safety of the trolley during walking, an audible and visual alarm is installed to remind others that the trolley is running, please pay a...

Abstract

The invention discloses an automatic dust unloading control system of a recirculation cooler trolley, belonging to the technical field of dust unloading of a recirculation cooler. The automatic dust unloading control system comprises an approach switch positioning system, a weighting sensor metering system, a wireless communication system and a PLC (programmable logic controller) control system; the lower part of a dust hopper adopts an annular dust unloading track for positioning a dust unloading trolley and enabling the dust unloading trolley to travel; a scroll valve is adopted for unloading dust, is driven by an electric deflector rod of a motor to unload dust, and is provided with a remote dust unloading control loop; and the aim of automatic dust unloading of the recirculation cooler trolley can be achieved through the approach switch positioning system, the weighting sensor metering system, the wireless communication system and the PLC control system, and the dust unloading of the recirculation cooler is ensured to meet the process requirement. The invention has the advantages of changing the running mode of manual dust unloading of the recirculation cooler, optimizing the dust unloading flow, and improving the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of ash unloading of annular coolers, and in particular provides an automatic ash unloading control system for a trolley of an annular cooler, which can be used for automatic ash unloading of a trolley of a sintering annular cooler, and can also be used for unloading ash of a trolley of a pelletizing annular cooler. It can be popularized and applied to automatic ash unloading in other metallurgical industries. Background technique [0002] The cooling equipment of the 360-square-meter sintering machine in the mining sintering plant is a 415-square-meter annular cooler. The ash unloading system of the annular cooler unloads the fine sintered material stored in the bellows of the annular cooling process to the annular cooling trolley through the worm valve, and then discharges the annular cooler The sintered material stored in the trolley is transported to the belt. [0003] There are 22 ash hoppers in the low...
