Burner air supply device

Abstract

The invention discloses a burner air supply device. The burner air supply device comprises an air inlet box body, the air inlet box body is a cylindrical hollow box body, a through hole is formed in the outer wall of the air inlet box body in a penetrating mode, and a stirring column in the air inlet box body is driven by a servo motor to rotate; when the stirring column rotates, a piston plate at the tail end of a piston rod can be driven by a transmission plate to do piston motion in an air blowing sleeve, and when the piston plate moves towards an air supply box, air in the air blowing sleeve can be discharged into the air supply box along an air guide sleeve and is discharged through an air supply pipe; a traditional fan blade air guide mode is replaced with a piston type air supply mode, the air guide amount can be effectively increased, combustion of the burner is not affected, and hot air backflow can be effectively prevented through the air supply box and an air guide sleeve; and meanwhile, when a rotating shaft drives the stirring column to rotate, the fan blades can be driven to rotate in the air guide sleeve, the fan blades can drive air to circulate, and heat dissipation can be effectively conducted on the device.

Description

technical field [0001] The invention relates to the technical field of air supply devices, in particular to a burner air supply device. Background technique [0002] A burner is a general term for a device that makes fuel and air eject and mix and burn in a certain way. Burners are classified into industrial burners, burners, civil burners and special burners according to their types and application fields. Among them, the industrial burner has a larger volume and consumes more oxygen during combustion. Therefore, an air blower is required to send the outside air to the inside of the burner through an air supply pipe. However, most of the existing air supply devices for burners use a single motor to drive the fan blades to supply air when supplying air. Since the fan blades of the fan have insufficient wind power when guiding the wind, the air supply effect will be poor. When the wind power is large, it will affect the combustion of the burner, and when the wind force is t...

Problems solved by technology

However, most of the existing air supply devices for burners use a single motor to drive the fan blades to supply air during air supply. Because the fan blades of the fan have insufficient wind force when guiding the air, the air supply effect will be poor. When the fan blades When the wind force is strong, it will affect the combustion of the burner, and when the wind force is too strong, it will cause the air to flow back, and the return air contains a lot of hot gas, which will greatly shorten the service life of the device
