Description

Technical Field

[0001] The utility model relates to the technical field of kiln burners, in particular to an energy-saving burner for high-speed stirring and mixing fuels. Background Art

[0002] The kiln burner is an important component of the kiln combustion system. It is used to mix fuel and air and send them into the kiln for combustion. The kiln burner can directly affect the combustion efficiency and production effect of the kiln. The current kiln burner is composed of a shell, a fuel center tube, an air vane, an air nozzle, an ignition electrode, etc. When the fuel and air are mixed, they are ignited by the ignition electrode to generate a high-temperature flame. The high-temperature flame will be sprayed into the kiln to burn the ceramics.

[0003] However, the sealing piece in the current burner is fixed inside the burner, which will make the fuel and air mix quickly, resulting in too short a mixing time for the fuel and air. In a short time, the fuel and air are difficult to mix evenly, which will cause carbon deposits in the burner due to incomplete combustion. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is that the mixing time of fuel and air in the current kiln burner is too short, which leads to incomplete combustion of the fuel and carbon deposits in the burner.

[0006] (II) Technical solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: an energy-saving burner for high-speed stirring mixed fuel, comprising a shell and an air duct located on one side of the shell, a flange fixedly connected to the air duct, a fuel pipe is arranged in the air duct, an air wind blade matched with the fuel pipe is arranged at one end of the air duct, an air inlet pipe matched with the air wind blade is arranged at the upper end of the shell, at least one ventilation hole uniformly arranged in a ring shape is arranged in the air wind blade, an annular electrode mounting plate matched with the fuel pipe and the air wind blade is arranged at one end of the air duct, at least one inner wall inclined guide plate uniformly arranged in a ring shape is fixedly connected in the air duct, a relatively high-temperature resistant bearing is arranged on one side of the inner wall inclined guide plate on the fuel pipe, and at least one forward blade and a reverse blade uniformly arranged in a ring shape are respectively fixedly connected to the high-temperature resistant bearings on both sides.

[0008] As an improvement, the annular electrode mounting plate is provided with at least one ignition electrode which is evenly arranged in an annular shape.

[0009] As an improvement, a gas pressure sensor is provided in the shell.

[0010] As an improvement, the flange is fixed on the air duct by bolts.

[0011] As an improvement, the inclination angle of the forward blade is the same as the inclination angle of the inner wall inclined guide plate, and the inclination angle of the reverse blade is opposite to the inclination angle of the forward blade.

[0012] (III) Beneficial effects

[0013] The advantages of the utility model compared with the prior art are: with the cooperation of the inclined guide plate on the inner wall, the forward blades and the reverse blades, the air flowing in the air duct will produce a swirl, and the rate of outflow from the air vanes can be slowed down, which can increase the contact time between air and fuel, and the swirl can make the air and fuel fully mixed, so that the fuel can be fully burned and carbon deposits can be avoided.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2 As shown, an energy-saving burner for high-speed stirring mixed fuel includes a shell 1 and an air duct 2 located on one side of the shell 1, a flange 5 is fixedly connected to the air duct 2, and the flange 5 is fixedly installed on the air duct 2 by bolts, a fuel pipe 3 is arranged in the air duct 2, one end of the air duct 2 is provided with an air wind blade 4 matched with the fuel pipe 3, an upper end of the shell 1 is provided with an air inlet pipe 6 matched with the air wind blade 4, the air wind blade 4 is provided with at least one ventilation hole evenly arranged in a ring shape, a gas pressure sensor is provided in the shell 1, which can be used to detect the gas pressure in the shell 1, one end of the air duct 2 is provided with an annular electrode mounting plate 7 matched with the fuel pipe 3 and the air wind blade 4, and the annular electrode mounting plate 7 is provided with at least one ignition electrode evenly arranged in a ring shape.

[0022] Through the above structure, the combustion-supporting air and fuel flowing out through the ventilation hole and the fuel pipe 3 respectively can be burned under the action of the ignition electrode. How to achieve efficient and full combustion of the fuel? The specific structure is as follows:

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, at least one inner wall inclined guide plate 11 is fixedly connected to the air duct 2 and is evenly arranged in a ring shape. On one side of the inner wall inclined guide plate 11, a relatively arranged high temperature resistant bearing 8 is provided on the fuel pipe 3. At least one forward blade 9 and a reverse blade 10 are fixedly connected to the high temperature resistant bearings 8 on both sides and are evenly arranged in a ring shape. The inclination angle of the forward blade 9 is the same as the inclination angle of the inner wall inclined guide plate 11, and the inclination angle of the reverse blade 10 is opposite to the inclination angle of the forward blade 9.

[0024] Through the above structure, before the combustion air flows out from the ventilation hole, with the cooperation of the inclined guide plate 11 on the inner wall, the forward blades 9 and the reverse blades 10, a swirl can be generated, and the flow rate when flowing out of the ventilation hole can be slowed down, so that the combustion air and the fuel can be fully mixed, and the mixing time is prolonged, which can achieve efficient and complete combustion of the fuel.

[0025] During the specific implementation of the utility model, during use, fuel is input through the fuel pipe and flows out through one end of the fuel pipe close to the air blade, air is input through the air inlet pipe, and then the air flows out through the ventilation holes in the air blade, and the ignition electrode on the annular electrode mounting sheet ignites the fuel and air, so that the fuel and air that flow out and mix together burn to generate flames;

[0026] When the air flows in the air duct, it will first pass through the inclined guide plate on the inner wall arranged in a ring. At this time, the air will swirl forward. The air after the forward swirl will pass through the forward blades. Under the action of the high-temperature resistant bearings, the forward blades will also rotate forward, promoting the air to maintain a forward swirl state. The air of the forward swirl will pass through the reverse blades after passing through the forward blades. At this time, the reverse blades will rotate in the opposite direction due to the air blowing, which can both disturb the air and cause the air to swirl. The air of the forward swirl will slow down and swirl in the opposite direction after being disturbed by the reverse blades, and finally flow out through the vents. In this way, the air flow rate will be reduced, and the air will swirl, which can improve the mixing efficiency of air and fuel, and increase the mixing time of air and fuel, so that the fuel can be fully burned.
