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] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the multi-burner synchronous linkage control device in front of the nozzle of the present invention includes a manual hoisting device 1, an actuator 2, a weight 4, and a plurality of valves 3 for controlling the on-off of the gas pipeline in front of the burner. The device 2 is a cylinder or an oil cylinder, and the end of the piston rod 21 of the cylinder or the oil cylinder is limited by a limit switch 9 arranged on the frame. Between the actuator 2 and the weight 4, the handle 31 of each valve 3 is connected to a connection device 5, one end of the connection device 5 is connected to the piston rod 21 through the first flexible steel cable 6, and the other end is connected to the piston rod 21 through the second flexible steel cable. Cable 7 links to each other with weight 4. The connection device 5 and the piston rod 21 adopt a flexible connection method, which greatly reduces the friction force dur...

Abstract

The invention discloses a multi-burner front synchronous linkage control device with stable performance, low price and suitable for various gas flows. The device includes a manual hoisting device, an actuator, a heavy hammer and multiple valves for controlling the on-off of the gas pipeline. The handles are all connected to a connecting device, one end of the connecting device is connected with the actuator through the first flexible steel cable, and the other end is connected with the weight through the second flexible steel cable.

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 ...
