Description

Technical Field

[0001] This application relates to the field of kiln technology, specifically to a kiln hybrid oxygen combustion system. Background Technology

[0002] Kilns are key equipment used in industrial production for high-temperature heating and processing of materials. They are widely used in industries such as ceramics, glass, metallurgy, and building materials. Their core function is to create a high-temperature environment in a closed or semi-closed space through fuel combustion or electric heating to achieve processes such as melting, sintering, calcination, and heat treatment of materials.

[0003] There are two heating methods for kilns: side firing and top firing. In top firing, a combustion torch is installed on the kiln arch, and the fuel is sprayed directly toward the surface of the glass tank furnace. Because the flame formed by the combustion of fuel in the top firing torch directly acts on the batch material layer and the surface of the molten glass, the heat transfer efficiency is high and the batch material melts quickly. In side firing, the torch is installed on the breast wall of the kiln, and the flame formed by the combustion of fuel is parallel to the surface of the glass tank furnace. The kiln combustion space mainly transfers energy to the glass tank furnace through the radiation heat transfer of the flame and the convection heat transfer between the high-temperature flue gas and the surface of the molten glass.

[0004] The two heating methods mentioned above each have their own advantages and disadvantages, and are therefore suitable for different application environments. Therefore, the problem of how to freely switch between the two heating methods or use both heating methods at the same time in a kiln needs to be solved. Summary of the Invention

The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0054] Please refer to Figures 1-4 This embodiment provides a kiln hybrid oxygen combustion system, including a melting pool 100 extending along a first direction and topped with a large arch 110.

A sealing component is provided inside the mounting hole 201, and a quick-connect component is provided at its end corresponding to the lance 300.

[0055] In this embodiment, the large arch 110 is located above the melting pool 100, and forms a closed combustion space above the melting pool 100 through the front wall 120, the rear mountain wall 130, and the breast wall 140 respectively; at the same time, nozzle bricks 200 are evenly arranged along the first direction on the large arch 110 and the breast wall 140 respectively, so that the corresponding burner 300 can be arranged according to the usage requirements.

[0056] In a preferred embodiment, the sealing assembly includes a first sliding plate 210 and a second sliding plate 220 located on both sides of the mounting hole 201; the first sliding plate 210 and the second sliding plate 220 are slidably connected to the nozzle brick 200 and slide in the same direction; the nozzle brick 200 is provided with grooves corresponding to the first sliding plate 210 and the second sliding plate 220, which communicate with the mounting hole 201.

[0058] In a preferred embodiment, the end of the first slide plate 210 is provided with a matching first mating groove 211 corresponding to the mounting hole 201, and the two sides are respectively provided with mutually parallel racks 212; the first mating groove 211 is semi-circular and has the same diameter as the mounting hole 201; the two sides of the slide groove are respectively provided with corresponding drive gears 230 corresponding to the racks 212, for driving the first slide plate 210 to slide relative to each other.

[0059] In this embodiment, the first sliding plate 210 is provided with a first docking groove 211 at one end near the mounting hole, and the first docking groove 211 is semi-circular. When the first sliding plate 210 is in the first state, the first docking groove 211 and the mounting hole 201 are coaxial, and the mounting hole 201 is in a connected state. When the first sliding plate 210 is in the second state, the first docking groove 211 is located on the side of the mounting hole 201 near the second sliding plate 220, thereby making the mounting hole 201 in a blocked state.

[0060] In this embodiment, racks 212 are provided on both sides of the first slide plate 210; at the same time, corresponding drive gears 230 are provided on the nozzle brick 200 corresponding to the two racks 212 respectively. By controlling the rotation of the drive gears 230, the first slide plate 210 can be effectively driven to slide relative to each other.

[0062] In this embodiment, the two drive gears 230 are respectively sleeved on the corresponding transmission shafts 232 and are rotatably connected to the nozzle brick 200 through the transmission shafts 232; at the same time, a worm gear 231 is also sleeved on the transmission shafts 232, so that the two transmission shafts 232 can be driven and connected to the same worm 240 respectively, thereby realizing the synchronous drive of the two drive gears 230.

[0065] In this embodiment, the second sliding plate 220 is slidably installed in the corresponding groove. One end near the mounting hole 201 is provided with a second mating groove 221 that matches the mounting hole 201, and the other end away from the mounting hole 201 is installed by abutting against the corresponding spring 222. When the second sliding plate 220 is in the reset state, the second mating groove 221 and the mounting hole 201 are in a coaxial position, thereby making the mounting hole 201 in a connected state. Conversely, when it is pressed by the first sliding plate 210, the second sliding plate 220 will press the spring 222, thereby blocking the mounting hole 201 by the first sliding plate 210.

[0066] In a preferred embodiment, the combustion gun 300 includes a coaxial oxygen pipe 310 and a gas pipe 320; the oxygen pipe 310 has a relatively large diameter and is sleeved on the gas pipe 320; the gas pipe 320 has a relatively long length, with both ends extending to the outside of the oxygen pipe 310.

[0068] In this embodiment, the gas pipe 320 is relatively long, with its end extending to the outside of the oxygen pipe 310. In operation, since the oxygen pipe 310 is relatively short, when oxygen is sprayed out, an airflow will be formed on the surface of the gas pipe 320, which can not only assist combustion but also cool the air.

[0070] In this embodiment, the snap-fit ​​plate 250 is provided with baffles on both sides of the through hole; the side of the baffle near the through hole is flat, and the side away from the through hole is curved, and the end of the curved surface is also curved along the axial direction, so that it can be connected to the snap-fit ​​plate 250 and form a snap-fit ​​groove with the snap-fit ​​plate 250; between the two snap-fit ​​grooves is a snap-fit ​​channel for the snap-fit ​​part to enter and exit.

[0071] In this embodiment, a clamp head 311 is fitted onto the oxygen tube 310; the clamp head has two symmetrical clamping parts about the oxygen tube 310; when installing the burner 300, first align the clamping parts on both sides of the clamp head 311 with the clamping channels on the clamping plate 250, and then clamp it with the clamping groove by rotating it.

[0072] In a preferred embodiment, the baffle has a matching groove at the middle of the snap-fit ​​portion for snapping with the snap-fit ​​portion; the snap-fit ​​plate 250 has a liftable elastic element corresponding to the groove for pressing the snap-fit ​​portion into the groove.

[0073] In this embodiment, a radially extending groove is provided in the middle of the baffle, and the opening of the groove faces one side of the snap-fit ​​plate 250, so that the snap-fit ​​part entering the snap-fit ​​groove can be further snap-fitted and positioned.

[0074] In this embodiment, a retractable elastic element is also provided on the corresponding groove of the snap-fit ​​plate 250; a through hole is provided on the snap-fit ​​plate 250 corresponding to the elastic element; the elastic element extends to the top of the snap-fit ​​plate 250 through the through hole, and has inclined surfaces on both sides, so that it can both provide elastic support for the snap-fit ​​part and allow the snap-fit ​​part to slide in and out through the inclined surfaces.
