[0039] Example

[0040] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0041] A biomass steam boiler, comprising:

[0042] Steam boiler 1;

[0043] A protective plate 2 is fixed to one side of the steam boiler 1;

[0044] A connecting hole 4 is provided at one side end of the protective plate 2;

[0045] An ignition device 3 is arranged on one side of the protective plate 2. An ignition head is arranged on one side end of the ignition device 3. The ignition head passes through the protective plate 2 and is connected to the steam boiler 1.

[0046] Two slots 5 are provided, both starting from one side end of the protective plate 2;

[0047] A fixing plate 17, fixed on the ignition device 3;

[0048] There are two plug blocks 6, both of which are fixed to one side of the fixing plate 17 and are movably inserted into the two slots 5 respectively;

[0049] The fixing mechanism is provided with two groups, and is used to fix the two inserting blocks 6 in the two slots 5 .

[0050] In a specific embodiment of the utility model, in the device, a base 20 is provided at the bottom of the steam boiler 1, and the steam boiler 1 is fixed to the top of the base 20 through a plurality of connecting seats 19, and is connected to the steam boiler 1 through an ignition device 3, and an ignition head on the ignition device 3 is ignited to start combustion in the steam boiler 1, and the degree of combustion of the ignition head can be controlled according to actual conditions, thereby controlling the degree of combustion in the steam boiler 1, and improving the combustion efficiency of the steam boiler 1. It should be noted that the ignition device 3 is a prior art, and how to ignite, as well as its internal structure and working principle, are also common knowledge of those skilled in the art. , no further elaboration is given to this. The ignition device 3 is installed on one side of the steam boiler 1, and the protective plate 2 is used to connect the ignition device 3. The connecting hole 4 provided on the protective plate 2 facilitates the ignition head to enter the steam boiler 1. When the ignition head of the ignition device 3 is inserted into the connecting hole 4, the ignition device 3 drives the plug block 6 to move through the fixing plate 17, so that the two plug blocks 6 are respectively inserted into the two slots 5. The two plug blocks 6 can be fixed in the two slots 5 by using the fixing mechanism. The two slots 5 are symmetrical based on the connecting hole 4, so that the ignition device 3 is more stable when fixed, so that the connection between the ignition head and the steam boiler 1 is more stable and not easy to loosen.

[0051] Specifically, each set of fixing mechanisms includes:

[0052] A card slot 7 is provided at one side end of the insert block 6;

[0053] A slide groove 9 is provided on an inner wall of one side of the slot 5;

[0054] The card block 8 is slidably connected in the slide groove 9, one end of the card block 8 is movably inserted in the card groove 7, and one side surface of the card block 8 is partially inclined;

[0055] A spring 10, one end of which is fixed to one side of the block 8, and the other end of which is fixed to one inner wall of the slide groove 9;

[0056] The limiting component is arranged in the slide groove 9 to limit the position of the clamping block 8.

[0057] In this embodiment: the plug block 6 is inserted into the slot 5 and first contacts the block 8. The side of the block 8 close to the plug block 6 is inclined. Therefore, when the plug block 6 contacts the block 8, the block 8 will be compressed into the slide groove 9 along the inclined surface. At the same time, the plug block 6 continues to extend inward. When the block 8 moves into the slide groove 9, the spring 10 is squeezed. When the plug block 6 is inserted into the slot 5 and reaches the bottom wall, the slot 7 on the plug block 6 matches the block 8. The elasticity of the spring 10 can reset the block 8 to be embedded in the slot 7, so as to achieve the block 6 being stuck and the plug block 6 cannot be pulled out, so that the ignition device 3 can be stably fixed to one side of the protective plate 2, so that the ignition head of the ignition device 3 is stably located in the steam boiler 1 and is not easy to loosen.

[0058] Specifically, each set of limiting components consists of two limiting grooves 12 and two limiting blocks 13. The two limiting grooves 12 are respectively opened on the inner walls on both sides of the slide groove 9, and the two limiting blocks 13 are respectively fixed on the two side ends of the clamping block 8. The two limiting blocks 13 are respectively slidably connected to the two limiting grooves 12.

[0059] In this embodiment: when the block 8 is compressed into the slide groove 9 and moves through the elastic reset of the spring 10, the block 8 drives the limit block 13 to slide in the limit groove 12. Both ends of the limit groove 12 are not open, so the position of the block 8 is limited and can only move in a straight line. It will not pop out into the slot 5, but only the inclined surface part will pop out into the slot 5, which is convenient for squeezing the block 8.

[0060] Specifically, a U-shaped pull rod 11 is provided on one side of the protective plate 2, and both ends of the U-shaped pull rod 11 are movable from one side of the protective plate 2 to the two slide grooves 9, and both ends of the two U-shaped pull rods 11 pass through two springs 10 and are fixed to the ends of the two blocks 8.

[0061] In this embodiment: through the U-shaped pull rod 11, when the ignition device 3 needs to be pulled out, the U-shaped pull rod 11 is pulled outward, and the U-shaped pull rod 11 can drive the two blocks 8 to move into the slide groove 9, so that the block 8 is disengaged from the slot 7, so that the plug block 6 can be pulled out of the slot 5, which is convenient for taking out the ignition device 3. The U-shaped pull rod 11 passes through the two springs 10, so that the springs 10 are not easily elastically deformed when compressed or reset.

[0062] Specifically, a sealing ring 14 is fixed to one end of the protection plate 2 close to the ignition device 3, so as to provide better sealing performance.

[0063] Specifically, threaded holes 16 are provided at four corners of the protection plate 2 , and the protection plate 2 is fixed to the steam boiler 1 by a plurality of bolts 15 .

[0064] In this embodiment, the protection plate 2 is threadedly penetrated through the threaded holes 16 by a plurality of bolts 15 and extends to the steam boiler 1, so that the protection plate 2 is fixed to the steam boiler 1, and is not easy to loosen and is easy to disassemble and assemble.

[0065] Preferably, a support plate 18 is fixed to one side end of the steam boiler 1. When the ignition device 3 is installed on one side of the steam boiler 1, the bottom of the ignition device 3 contacts the top of the support plate 18. The support plate 18 can further support the ignition device 3, making the ignition device 3 more stable.

[0066] Working principle and use process of the utility model: when installing the ignition device 3 of the device, first align the ignition head on the ignition device 3 with the connecting hole 4, and align the two plug blocks 6 with the two slots 5 respectively. At this time, push the ignition device 3 in the direction of the steam boiler 1 so that the ignition head is connected to the steam boiler 1. The plug block 6 is inserted into the slot 5 and first contacts the card block 8. The card block 8 will be compressed into the slide groove 9 along the inclined surface. The spring 10 will be squeezed when the card block 8 moves into the slide groove 9. When the plug block 6 is inserted into the slot 5 and reaches the bottom wall, the card groove 7 on the plug block 6 matches the card block 8. The elasticity of the spring 10 can make the card block 8 reset and embed into the card groove 7, so as to achieve the jamming of the plug block 6, so that the plug block 6 cannot be pulled out, so that the ignition device 3 can be stably fixed to one side of the protective plate 2, so that the ignition head of the ignition device 3 is stably located in the steam boiler 1 and is not easy to loosen.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
