[0023] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.
[0024] The present application is described below with reference to Figure 1 A gasification furnace 10 according to an embodiment of the present application is described below, which comprises a gasification furnace body 11, a positioning block 12 and a detection piece 13.
[0025] A gasification cavity 111 is formed in the gasification furnace body 11, which is adapted to accommodate materials. The positioning block 12 is arranged on the gasification furnace body 11, and at least part of the positioning block 12 is located in the gasification cavity 111. The detection piece 13 is arranged on the gasification furnace body 11, and the detection piece 13 is formed with a detection end 131 extending into the gasification cavity 111, which is adapted to detect a signal of the positioning block 12 to determine the material level in the gasification cavity 111.
[0026] At present, whether the furnace condition in the gasification furnace is stable often depends on whether the material level in the gasification furnace is stable, and whether the material level is stable also determines whether the entire device can be safely and efficiently operated. In order to detect the material level in the gasification furnace, the existing gasification furnace is generally provided with a material level meter inside, which is generally a radiation source material level meter, a blocking material level meter, a temperature sensor, a radar material level meter, etc. However, the above-mentioned material level meter is easily affected by the temperature, pressure, feeding and radiation of the gasification furnace, which affects the detection of the material level meter, resulting in that the material level meter has great limitations in use.
[0027] To this end, the embodiment of the present application provides a gasification furnace 10, which can include a gasification furnace body 11, a positioning block 12 and a detection member 13. The gasification furnace body 11 can be internally formed with a gasification cavity 111, which can be used to accommodate materials. The positioning block 12 can be arranged on the gasification furnace body 11. Optionally, the positioning block 12 and the gasification furnace body 11 are detachably connected through screws, bolts, or detachably connected through clamping or insertion, or fixed through adhesion or welding.
[0028] The detection member 13 can be arranged on the gasification furnace body 11, and the detection member 13 can be formed with a detection end 131 extending into the gasification cavity 111, and the detection end 131 can detect the signal of the positioning block 12 to determine the material level in the gasification cavity 111.
[0029] It should be noted that the positioning block 12 can be arranged at the lower end of the gasification furnace body 11, i.e., at the lowest value of the required added material in the gasification cavity 111. The detection member 13 determines whether the material reaches the lowest value by detecting the signal of the positioning block 12. If the material is too little, it will affect the subsequent gasification. Alternatively, the positioning block 12 can be arranged at the upper end of the gasification furnace body 11, i.e., at the highest value of the required added material in the gasification cavity 111. The detection member 13 determines whether the material reaches the highest value by detecting the signal of the positioning block 12. If the material is too much, it will lead to incomplete gasification.
[0030] The signal of the positioning block 12 can be a light signal, a temperature signal, a sound signal, etc. The signal of the positioning block 12 is detected by the detection member 13 to determine the position of the material in the gasification cavity 111, thereby ensuring that the gasification furnace 10 can operate safely and efficiently. Since the detection member 13 and the positioning block 12 are fixed to the gasification furnace body 11, they are not easily affected by the environment in the furnace, have higher reliability, and have wider applicability.
[0031] In short, the gasification furnace 10 of the embodiment of the present application has the gasification furnace body 11, the positioning block 12 and the detection member 13. The positioning block 12 and the detection member 13 are connected to the gasification furnace body 11, and at least part of the positioning block 12 can extend into the gasification cavity 111. The detection member 13 is formed with a detection end 131 extending into the gasification cavity 111. The detection end 131 can detect the signal of the positioning block 12 to determine the material level in the gasification furnace body 11, ensure that the material level in the gasification furnace body 11 meets the requirements, and make the gasification furnace 10 operate stably and efficiently. Moreover, the detection member 13 and the positioning block 12 are not easily affected by the environment in the furnace, thereby improving the reliability and applicability of the gasification furnace 10.
[0032] As Figure 1As shown in the figure, in some embodiments of the present application, the number of positioning blocks 12 can be multiple, and the multiple positioning blocks 12 can be arranged at intervals along the first direction on the gasifier body 11. It can be understood that the first direction can be the height direction of the gasifier 10. By arranging multiple positioning blocks 12, the detection member 13 can detect the specific position of the material in the gasifier body 11, so as to determine whether the material in the gasifier body 11 needs to be continuously added. For example, the detection member 13 can determine whether the material reaches the required minimum content or maximum content by detecting the signals of the multiple positioning blocks 12, and then determine whether the material in the gasifier 10 is stable.
[0033] As shown in the figure, Figure 1 As shown in the figure, in some embodiments of the present application, the distance between the detection end 131 and the bottom of the gasifier body 11 along the first direction is h1. It should be noted that the bottom of the gasifier 10 is defined as the base surface, and the bottom referred to herein can be any position at the bottom end of the gasifier 10. h1 can be the distance between the detection end 131 and the base surface in the height direction. The maximum distance between the positioning block 12 and the bottom of the gasifier body 11 is h2. It should be noted that the number of positioning blocks 12 can be multiple, and the maximum distance between the positioning block 12 and the bottom of the gasifier body 11 can refer to the distance between the positioning block 12 close to the upper end of the gasifier body 11 and the base surface in the height direction. The distance between the detection end 131 and the bottom of the gasifier body 11 and the maximum distance between the positioning block 12 and the bottom of the gasifier body 11 satisfy the relationship h1≥h2. It can be understood that the detection end 131 can be kept horizontal with the positioning block 12 close to the upper end of the gasifier body 11 or the detection end 131 can be higher than the positioning block 12 close to the upper end of the gasifier body 11. For example, the detection end 131 can be installed at the upper empty layer part of the material layer of the gasifier 10. Such arrangement can ensure that the detection end 131 can timely detect the signals of all positioning blocks 12, avoid that the material in the gasifier body 11 is too much and blocks the detection end 131 to affect the normal detection of the detection end 131, and ensure the reliability of the detection member 13.

The multiple first mounting holes 112 can be arranged one-to-one corresponding to the multiple positioning blocks 12, to ensure that the gasifier body 11 provides a certain space for the installation of the positioning blocks 12, and at the same time, to ensure that at least part of the positioning blocks 12 can extend into the gasification cavity 111 for detection by the detection member 13. The gasifier body 11 can also be formed with a second mounting hole 113 arranged through in the second direction, and the detection member 13 can be arranged through the second mounting hole 113, to ensure that the gasifier body 11 provides a certain space for the installation of the detection member 13.
