Referring to fig. 1 and 2, the present embodiment provides an annular combustor 100, including a first annular flow path 110 disposed below an object placing groove 105, and a second annular flow path 120 concentrically disposed with the first annular flow path 110, where the first annular flow path 110 is located at an inner ring of the second annular flow path 120, the first annular flow path 110 is provided with a plurality of first nozzles 115, the second annular flow path 120 is provided with a plurality of second nozzles 122, the first nozzles 115 and the second nozzles 122 face the object placing groove 105, the first annular flow path 110 is used for flowing gas and oxygen, and the second annular flow path 120 is used for flowing compressed air.

It should be noted that, first, the number of the first nozzles 115 and the second nozzles 122 is not specifically limited in the embodiment of the present invention, for example, the number of the first nozzles 115 and the number of the second nozzles 122 may be respectively set to 3 to 20, for example, the number of the first nozzles 115 and the number of the second nozzles 122 may be respectively set to 5, 8, 12, or 16, and the like, and may be flexibly set according to needs. In addition, the number of the first nozzles 115 and the second nozzles 122 may be equal or may not be equal. For example, the first nozzle 115 and the second nozzle 122 are each provided in 8, or the first nozzle 115 is provided in 8 and the second nozzle 122 is provided in 12.

Second, the first and second

annular flow paths

110 and 120 have a predetermined distance from the bottom of the housing 105 to ensure that the gas is normally combusted at the first nozzle 115 and the compressed air is normally injected at the second nozzle 122. In addition, the first annular flow path 110 and the second annular flow path 120 may be located on the same plane or may be located on different planes. For example, the distances between the first annular flow path 110 and the bottom of the housing container 105 and the second annular flow path 120 may be set to be equal to each other, or the distance between the first annular flow path 110 and the bottom of the housing container 105 may be set to be smaller than the distance between the second annular flow path 120 and the bottom of the housing container 105.

Thirdly, acetylene or methane can be used as the fuel gas, so long as the requirement of providing the required heat value for discharging in a short time can be met. The first nozzle 115 and the second nozzle 122 face the object placing groove 105, so that the bottom of the object placing groove 105 can directly receive the heat value of the first nozzle 115 and can also directly receive the cooling of the second nozzle 122, and the material unloading process can be better controlled. Before unloading, the raw materials in the object placing groove 105 are in a heat preservation state, but the bottom channel of the object placing groove 105 can be solidified to form a physical plug, so that the raw materials cannot flow out of the channel, when the bottom of the object placing groove 105 is heated through the first annular flow path 110, the physical plug formed by the bottom channel of the object placing groove 105 through solidification is heated and melted, and finally the raw materials flow out through the channel. If the discharge is to be terminated, the bottom of the holding tank 105 is cooled by the second annular flow path 120 so that the material in the channel gradually solidifies to form a physical plug to terminate the discharge.

According to the annular combustor 100 provided by the embodiment of the invention, through the first annular flow path 110 arranged below the object placing groove 105 and the plurality of first nozzles 115 arranged on the first annular flow path 110, when the first annular flow path 110 is introduced with gas and oxygen to circulate the gas and the oxygen in the first annular flow path 110, the first nozzles 115 of the first annular flow path 110 can be combusted and heated to achieve the purpose of discharging. When compressed air is introduced into the second annular flow path 120 through the second annular flow path 120 concentrically arranged with the first annular flow path 110 and the plurality of second nozzles 122 provided in the second annular flow path 120, the compressed air is jetted through the second nozzles 122 to rapidly cool the material. The annular combustor 100 provided by the embodiment of the invention has two functions of heating and cooling, can quickly unload materials and control the unloading amount, and is beneficial to normal implementation of defect countermeasures and production emergencies.

As shown in fig. 1, the annular combustor 100 further includes a first air inlet passage 130 communicated with the first annular flow path 110, the first air inlet passage 130 includes a first branch 132 and a second branch 134, the first branch 132 is used for introducing fuel gas, and the second branch 134 is used for introducing oxygen gas.

Specifically, the first branch 132 is communicated with a gas source of fuel gas, the second branch 134 is communicated with a gas source of oxygen, the first annular flow path 110 is communicated with the gas source of fuel gas through the first branch 132, and the second branch 134 is communicated with a gas source of residual oxygen in the first annular flow path 110, so that a combustion environment at the position of the first nozzle 115 can be provided, and the stability of discharging is ensured.

As shown in fig. 1 and 2, the first annular flow path 110 includes a first annular conduit 112, and a second annular conduit 114 disposed outside the first annular conduit 112, the first annular conduit 112 is in communication with a first branch 132, the second annular conduit 114 is in communication with a second branch 134, and the first nozzle 115 is in communication with the first annular conduit 112 and the second annular conduit 114, respectively.
