Description

Technical Field

[0001] The present application relates to the field of combustion equipment, and in particular to a gas supply device for a gasification burner. Background Art

[0002] In the prior art, materials often need to be dried or preheated during production in industries such as steel and metallurgy. Drying materials can prevent splashing and explosion accidents when water-containing materials enter the furnace, which is of great significance to ensuring production safety. Preheating materials can make room temperature materials reach a temperature closer to the smelting temperature in the furnace, which is of great significance to improving production efficiency and saving energy and reducing consumption. Burners have been widely used because of their high combustion temperature and high heating efficiency.

[0003] Burners mostly use a technology in which gas pipes, air pipes and oxygen pipes are mixed in the burner and then directly sprayed out for combustion. However, existing combustion devices are generally only connected to one gas pipe, one air pipe and one oxygen pipe. If one of the pipes is damaged or leaks, combustion cannot continue in the furnace, seriously affecting production efficiency and production quality. In addition, during use, the combustion area is relatively concentrated, and oxygen and natural gas are not mixed evenly, resulting in incomplete combustion. The incompletely burned gas will produce harmful gases and pollutants, causing pollution to the environment. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a gas supply device for a gasification burner, which can solve the technical problem of achieving non-stop maintenance when a leak occurs during the gas supply to the burner.

[0005] The embodiment of the present application provides an air supply device for a gasification burner, comprising a cylinder, an air inlet end of the cylinder is provided with a mixing cavity, a peripheral wall of the mixing cavity is connected with a plurality of air inlet pipes, an air inlet mechanism is provided on the air inlet pipes, and a mixing mechanism is provided in the mixing cavity;

[0006] The air intake mechanism comprises a mounting plate, a rotating assembly and a plurality of connecting assemblies, wherein the plurality of connecting assemblies are circumferentially fixedly arranged on the rotating assembly, the rotating assembly is rotatably mounted on the mounting plate, and the mounting plate is connected to the air intake pipe.

[0007] Furthermore, the rotating assembly includes a rotary disk and a first motor. The rotary disk is rotatably mounted in the mounting disk, and the first motor drives the mounting disk to rotate.

[0008] Furthermore, at least two through holes are formed on the swirl cake, and a sealing ring is provided on the surface of the swirl cake that contacts the mounting plate.

[0009] Furthermore, the connecting assembly includes a connecting pipe and a sleeve, the sleeve is threadedly connected to the outer wall of the connecting pipe, the connecting pipe is fixedly arranged on the rotary disk, and the connecting pipe is connected to the through hole.

[0010] Furthermore, a clamping strip is spirally provided on the inner wall of the sleeve that is connected to the trachea.

[0011] Furthermore, a gas flow rate meter is provided on the air inlet pipe.

[0012] Furthermore, a pipeline control valve is provided on the air intake pipe.

[0013] Furthermore, the mixing mechanism includes a second motor, a rotating block and a plurality of stirring blades. The rotating block is arranged in a conical shape and is rotatably installed in the mixing chamber. The second motor drives the rotating block to rotate, and the plurality of stirring blades are respectively spirally fixed on the side walls of the rotating block.

[0014] Beneficial effects of the utility model:

[0015] The air intake mechanism provided by the utility model comprises a mounting plate, a rotating assembly and a plurality of connecting assemblies. By connecting various ventilation pipes with the connecting assemblies, a plurality of gases are allowed to enter the mixing chamber at the same time, and are mixed by the mixing mechanism and then discharged from the cylinder to the burner. If the ventilation pipe leaks, the connecting assembly can be driven to rotate by the rotating assembly, so that another ventilation pipe is connected to the mixing chamber. The leaking ventilation pipe can be stopped and repaired quickly without affecting the normal operation of the burner, thereby ensuring the production efficiency and production quality of the combustion chamber.

[0016] Through the setting of the mixing mechanism, the second motor drives the rotating block to rotate in the mixing chamber, which can effectively stir and mix the combustion gases discharged from multiple intake pipes, so that the multiple gases are evenly mixed and burned more fully.
