Description

Technical Field

[0001] The utility model belongs to the technical field of burners, and particularly relates to a novel burner prefabricated part. Background Art

[0002] A burner can be understood as the abbreviation of "burning nozzle". A burner is also called a combustor. A combustor is one of the most common heat source devices and is widely used in fields such as boilers, heating furnaces, and industrial kilns. A burner prefabricated part usually refers to a component installed on a combustion device, which is responsible for controlling the mixing and injection of fuel and air and determines the shape and characteristics of the final flame.

[0003] Many domestic kilns use a direct injection nozzle burner prefabricated part for calcining products. This kind of burner prefabricated part usually has only one flame outlet. The biggest defect of this method is that the fuel and air cannot be fully mixed, resulting in incomplete combustion of the fuel, thus affecting the heating rate and causing waste of fuel. Content of the Utility Model

[0004] In view of this, in order to solve the problems existing in the prior art, the purpose of the utility model is to provide a novel burner prefabricated part, which has the effect of enabling full mixing of fuel and air, and can effectively control the mixing ratio of fuel and air and the flame outlet state.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A novel burner prefabricated part, comprising: a body, a combustion chamber is formed in the body, a feed port communicating with the combustion chamber is opened at one end of the body, a first flame outlet communicating with the combustion chamber is opened at the other end of the body, a plurality of second flame outlets are opened on the outer side wall of the body, each second flame outlet penetrates through the outer side wall of the body to the combustion chamber, and each second flame outlet extends obliquely downward towards the direction close to the feed port;

[0007] A plurality of plugging components, the plurality of plugging components are all arranged on the outer side wall of the body, the plugging components are arranged in one-to-one correspondence with the second flame outlets, and one end of the plugging component can operably plug the second flame outlet.

[0008] The specific technical effects are as follows: By providing a number of second flame nozzles on the outer side wall of the main body, after the fuel burns, it can be ejected from the side wall, which can effectively control the mixing ratio of the fuel and air, promote full mixing and uniform combustion, thereby improving the thermal efficiency and reducing pollutant emissions. Moreover, by designing the number and shape of the second flame nozzles according to the actual situation, it can also be used to control the shape and size of the combustion flame to meet the calcination requirements of different products in the kiln. A blocking component is provided on each second flame nozzle, which can operably block or open the second flame nozzle, effectively controlling the flame ejection state and meeting the calcination requirements of different products.

[0009] Further, each of the blocking components includes a connecting member, a left blocking member, and a right blocking member. The connecting member is disposed on the outer side wall of the main body and close to the second flame nozzle. One end of the left blocking member is rotatably connected to the connecting member, and the other end of the left blocking member operably blocks a part of the second flame nozzle. One end of the right blocking member is rotatably connected to the connecting member, and the other end of the right blocking member operably blocks another part of the second flame nozzle.

[0010] The specific technical effects are as follows: The left blocking member and the right blocking member approach or move away from each other, thereby blocking or opening the second flame nozzle.

[0011] Further, each of the blocking components further includes a movement component. Both ends of the movement component are respectively disposed on the other ends of the left blocking member and the right blocking member, and the middle part of the movement component is threadedly connected through a double-headed nut.

[0012] The specific technical effects are as follows: Through the threaded connection between the movement component and the double-headed nut, the left blocking member and the right blocking member can approach or move away from each other, thereby playing a role in blocking the second flame nozzle.

[0013] Further, the movement component includes a left connecting rod, a right connecting rod, a left support seat, and a right support seat. The left support seat is disposed on the other end of the left blocking member. One end of the left connecting rod penetrates through the left support seat, and the other end of the left connecting rod is threadedly connected to the left end of the double-headed nut. The right support seat is disposed on the other end of the right blocking member. One end of the right connecting rod penetrates through the right support seat, and the other end of the right connecting rod is threadedly connected to the right end of the double-headed nut.

[0014] The specific technical effect is as follows: The other end of the left connecting rod is threadedly connected to the left end of the double-headed nut, and the other end of the right connecting rod is threadedly connected to the right end of the double-headed nut.

[0015] Further, the body is arranged in a frustum structure, and the diameters of both the combustion chamber and the body gradually decrease in the direction from the feed port to the first flame outlet.

[0016] The specific technical effect is as follows: With the design of the frustum structure, the air enters from the feed port with a larger diameter and a slower air flow velocity. When it reaches the first flame outlet with a smaller diameter, due to the sudden decrease in area, according to the continuity equation, the air flow will accelerate and eject. Appropriate high-speed air flow is beneficial to the good mixing of fuel and air, forming a uniform and stable flame; the first flame outlet with a smaller diameter will increase the jet adhesion force, and the flame is easily attached around the nozzle opening, thereby enhancing the stability of the flame and avoiding the phenomena of flame drift or backflow.

[0017] Further, each of the second flame outlets is arranged in a cylindrical structure.

[0018] The specific technical effect is as follows: The design of the second flame outlet with a cylindrical structure can make the air flow distribution uniform.

[0019] Further, an angle α is formed between the axis of each second flame outlet and the generatrix of the body, and the range of α is 125° to 130°.

[0020] The specific technical effect is as follows: By reasonably designing the angle α, the space of the combustion chamber can be utilized to the maximum extent, achieving full combustion and improving the thermal efficiency.

[0021] Further, a plurality of the second flame outlets are arranged in an annular array around the axis of the body.

[0022] The specific technical effect is as follows: The design of the annular array makes the positions of the ejected flames more uniform.

[0023] The beneficial effects of the present utility model are as follows:

[0024] (1) By providing a plurality of second flame outlets on the outer side wall of the body, the fuel can be ejected from the side wall after combustion, which can effectively control the mixing ratio of fuel and air, promote full mixing and uniform combustion, thereby improving the thermal efficiency and reducing pollution emissions.
