Description

Technical Field

[0001] The utility model relates to the technical field of ignition equipment, in particular to a plasma burner. Background Art

[0002] A plasma burner is a burner that uses high-temperature plasma generated by a plasma generator to ignite pulverized coal, and belongs to a type of internal combustion burner. Its working principle is to use direct current to strike an arc in the plasma carrier air, and obtain plasma under the control of a strong magnetic field. Through the high-temperature zone formed by its own primary combustion cylinder, the pulverized coal particles are broken and pulverized within microseconds to achieve the combustion process. Compared with the mainstream product of the igniter market, the high-energy igniter, the plasma igniter can ignite combustion media such as low-calorie fuels and pulverized coal, and has the advantages of fuel saving, environmental protection, low maintenance cost, high combustion efficiency, simple structure, high safety, and convenient installation. It is mainly applied to the field of thermal power combustion control.

[0003] The prior art such as the utility model with the publication number of CN206001505U discloses a plasma burner. The patent adopts a burner body with a channel running through both ends of the burner body. The burner body is provided with a burner nozzle. One end of the burner body is an oxygen channel for introducing oxygen into the channel, and the other end of the burner body is an input channel for introducing atomized water or hydrocarbon gas into the channel; an anode device and a cathode device insulated from the medium introduced into the channel are arranged in the channel, and an arc-striking space is formed between the anode device and the cathode device. The arc-striking space is communicated with the burner nozzle, and a high-frequency power supply for energizing the anode device and the cathode device to form an arc in the arc-striking space between the anode device and the cathode device. Under the action of the arc, the medium introduced into the channel undergoes an ionization chemical reaction and forms a high-temperature flame that sprays out from the burner nozzle; the plasma burner of the utility model has low input cost, the input medium is easy to obtain, and it will not pollute the air, solving the problems that the current equipment and technology of arc plasma are relatively simple, the design is unreasonable, affecting the use of plasma, and at the same time, the heat generated by the plasma cannot be reasonably utilized.

[0004] During the process of ignition operation with the help of a plasma burner, there are movable plasma burners on the existing market, which mostly rely on the design of rollers to achieve free movement. When the equipment is working, due to the lack of a limiting structure for the equipment rollers, the equipment will shake during the operation, resulting in changes in the shape and position of the flame generated by the equipment, affecting the uniformity and stability of combustion. At the same time, being in a shaking state for a long time will cause damage to the overall structure of the burner and reduce the service life of the equipment. Summary of the Utility Model

A U-shaped frame is rotatably connected to the surface of the connecting slider. A positioning hole is provided on the surface of the U-shaped block. The U-shaped frame is rotatably connected to the inner wall of the positioning hole.

[0009] Preferably, the number of the guide rods is two. The two guide rods are symmetrically arranged about the positioning plate.

Through the arc-shaped buckling frames installed below the connecting pressing plate, the position of the damping gasket can be restricted to ensure that the damping gasket can be stably pressed against the surface of the roller.

[0011] Preferably, the damping gasket is arc-shaped. Through the damping gasket installed below the arc-shaped buckling frame, when contacting the roller, the resistance of the roller can be increased to restrict the roller, thereby increasing the stability of the roller in the static state.

[0013] Preferably, the connecting slider is slidably connected to the lower part of the positioning plate, and the connecting slider is cross-shaped.

When locking the roller, the switch of the servo motor is turned on, and the servo motor is energized to drive the bidirectional threaded shaft. The bidirectional threaded shaft meshes with the connecting sliders on both sides and cooperates with the connecting sliders to push the U-shaped frame. The U-shaped frame pushes the U-shaped block under force, and the U-shaped block pushes the connecting pressing plate downward under the action of the U-shaped frame. The connecting pressing plate pushes the arc-shaped buckle frame downward under the guidance of the guide rod, and the arc-shaped buckle frame pushes the damping gasket, so that the damping gasket abuts against the surface of the roller. When the damping gasket is squeezed on the surface of the roller, the damping gasket cooperates with the arc-shaped buckle frame to lock the state of the roller, and then the locking operation of the roller can be realized. By setting the auxiliary component, the roller of the device can be locked, thereby reducing the problem that the roller is in a movable state during the ignition of the device, resulting in shaking and interfering with the flame during the ignition process of the device, and further improving the stability of the device during the ignition operation and the service life of the device.

[0030] Specifically, the damping gasket 515 is arc-shaped. Through the damping gasket 515 installed below the arc-shaped buckle frame 514, when contacting the roller 3, the resistance of the roller 3 can be increased to restrict the roller 3, thereby increasing the stability of the roller 3 in the stationary state.
