DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] See also Figure 1-Figure 4 The present application provides a gasification hot blast furnace with controllable combustion speed, including a gasification hot blast furnace body 10 and a furnace ash and slag barrier assembly 20.

[0025] Among them, the gasification hot blast furnace body 10 can burn carbon to achieve gasification, thereby achieving heating, and the ash and slag blocking component 20 can intercept unburned ash to prevent unburned carbon from falling into the ash and slag chamber 110, causing incomplete combustion of carbon and wasting carbon resources.

[0026] See also Figure 1 and Figure 2 The gasification hot blast furnace body 10 includes a combustion chamber 120. Specifically, the combustion chamber 120 is located above the ash blocking net 210 and is also provided with an inspection door 121, which can facilitate the dredging of the ash blocking net 210 to prevent the ash blocking net 210 from being blocked. The bottom of the combustion chamber 120 is connected to the ash chamber 110; specifically, a support leg 160 is installed at the bottom of the ash chamber 110. An extractable ash bin 170 is arranged inside the ash chamber 110. A first handle 180 is installed on the outside of the ash bin 170. A blocking door is installed on the ash chamber 110. The combustion chamber 120 is connected to a hot air chamber 130, the top of the hot air chamber 130 is connected to a hot air outlet 140, and the side of the hot air chamber 130 is connected to a feed pipe 150. The fully burned ash falls into the ash bin 170 to collect the ash. When there is too much ash, open the blocking door, put on scald-proof gloves, grab the first handle 180, pull out the ash bin 170 and dump the ash for centralized treatment.

[0027] In this embodiment, the combustion speed inside the combustion chamber 120 can be controlled by controlling the air intake volume. The specific control method is known to those skilled in the art and will not be described in detail here.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The ash and slag retaining assembly 20 includes an ash retaining net 210. A pull-out opening is provided on the side of the combustion chamber 120. The ash retaining net 210 is detachably arranged inside the combustion chamber 120 through the pull-out opening. A connecting plate 220 is fixedly connected to the ash retaining net 210 at the pull-out opening. The connecting plate 220 is detachably connected to a limiting plate 230. Specifically, a second handle 250 is installed on the limiting plate 230, and the limiting plate 230 blocks the pull-out opening. Among them, when the carbon material enters the combustion chamber 120 through the feed pipe 150, it will fall on the ash blocking net 210. The fully burned carbon material will become ash slag and fall into the ash slag chamber 110 through the holes of the ash blocking net 210. The carbon-containing material that is not fully burned will still be blocked on the ash blocking net 210 and continue to burn. When the ash blocking net 210 will be burned thin after long-term use and needs to be replaced, pull the second handle 250 so that the limit plate 230 drives the ash blocking net 210 to be pulled out from the combustion chamber 120, and then the ash blocking net 210 can be replaced. After replacement, grab the second handle 250, align the ash blocking net 210 with the pull-out slot, and push the ash blocking net 210 into the combustion chamber 120 to continue working. By setting the ash blocking net 210, it can be ensured that the carbon-containing material that is not fully burned will not fall into the ash chamber 110, thereby ensuring that the carbon-containing material in the combustion chamber 120 can be fully burned, thereby preventing the waste of resources, saving resources, and reducing production costs. The ash blocking net 210 can be detachably set inside the combustion chamber 120, so that the ash blocking net 210 can be easily replaced, thereby ensuring the normal operation of the ash blocking net 210.

[0029] In this embodiment, auxiliary fixing members 240 are hingedly provided at both ends of the limiting plate 230, and the auxiliary fixing members 240 are tautly provided on the outside of the combustion chamber 120. The auxiliary fixing member 240 includes auxiliary fastening plates 241, one end of the two auxiliary fastening plates 241 is hingedly provided at both ends of the limiting plate 230, and the other two ends of the two auxiliary fastening plates 241 bypass the outside of the combustion chamber 120 and are detachably connected to each other. One end of the two auxiliary fastening plates 241 away from the limiting plate 230 is fixedly connected with an ear plate 242, and the two ear plates 242 are screwed with connecting bolts 243. Among them, when the ash blocking net 210 is pushed into the interior of the combustion chamber 120, the two auxiliary fastening plates 241 are rotated so that the two auxiliary fastening plates 241 can surround the combustion chamber 120, and then the two auxiliary fastening plates 241 are connected with connecting bolts 243, so that the limiting plate 230 can be fixed, thereby making the ash blocking net 210 more stable inside the combustion chamber 120, preventing gaps between the limiting plate 230 and the pull-out opening.

[0030] The working principle of the gasification hot air stove with controllable combustion rate:

[0031] When the carbon material enters the combustion chamber 120 through the feed pipe 150, it will fall on the ash net 210. The fully burned carbon material will become ash slag and fall into the ash slag chamber 110 through the holes of the ash net 210. The carbon-containing material that is not fully burned will still be blocked on the ash net 210 and continue to burn. When the ash net 210 is burned thin after long-term use and needs to be replaced, pull the second handle 250 so that the limit plate 230 drives the ash net 210 to be pulled out from the combustion chamber 120, and then the ash net 210 can be replaced. After replacement, grab the second handle 250, align the ash net 210 with the pull-out slot, and push the ash net 210 into the combustion chamber 120 to continue working. By setting the ash blocking net 210, it can be ensured that the carbon-containing material that is not fully burned will not fall into the ash chamber 110, thereby ensuring that the carbon-containing material in the combustion chamber 120 can be fully burned, thereby preventing the waste of resources, saving resources, and reducing production costs. The ash blocking net 210 can be detachably set inside the combustion chamber 120, so that the ash blocking net 210 can be easily replaced, thereby ensuring the normal operation of the ash blocking net 210.
