Problems solved by technology
Using manual operation, the workload is heavy and the operation time is long. Usually, the ambient temperature in front of the burner is relatively high and the conditions are relatively harsh, so there are certain potential safety hazards.
With the development of modern technology, the stand-alone capacity of industrial furnaces and kilns is increasing, the number and number of burners on the equipment are increasing, and the amount of manual operation in front of the burners is also increasing, and it is extremely unsafe and prone to operation ACCIDENT

Embodiment Construction
[0026] As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the synchronous linkage control device in front of the multi-burner mouth of the present invention includes a manual hoisting device 1, an actuator 2, a weight 4, and a control device for controlling the passage of the gas pipeline in front of the burner. A plurality of valves 3 that are disconnected. In this embodiment, the actuator 2 is an air cylinder or an oil cylinder. The end of the piston rod 21 of the air cylinder or oil cylinder is limited by the limit switch 9 arranged on the frame. The rope 11 is connected with the piston rod 21, the valve 3 is arranged between the actuator 2 and the weight 4, the handle 31 of each valve 3 is connected in series through the connection device 5, and one end of the connection device 5 is connected to the piston rod 21 through the first flexible steel cable 6. The other end is connected with the weight 4 through the second flexible steel cable 7. The connection device 5 and the pist...

Description
technical field [0001] The invention relates to the field of thermal equipment, in particular to a synchronous linkage control device for an industrial furnace with multiple burners. Background technique [0002] At present, domestic large-scale industrial furnaces are usually equipped with multiple rows of burners, and the number of burners in each row is several or even dozens, and most of the operations before the burners are manually controlled. Manual operation requires heavy workload and long operation time. Usually, the ambient temperature in front of the burner is relatively high and the conditions are relatively harsh, so there are certain potential safety hazards. With the development of modern technology, the stand-alone capacity of industrial furnaces is increasing, the number and number of burner rows on the equipment are increasing, and the amount of manual operation in front of the burners is also increasing, and it is extremely unsafe and prone to operation ...
