[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a coal-saving high-temperature boiling furnace, comprising a support seat 1 and a boiling furnace body 16, a fixed seat 2 is fixedly connected to the top of the support seat 1, a limiting plate 19 is fixedly connected to the other side of the top of the support seat 1, a support frame 3 is fixedly connected to one side of the fixed seat 2, a cylinder 8 is fixedly connected to the top of the fixed seat 2, a blocking plate 9 is fixedly connected to the output end of the cylinder 8, a slide groove 7 is arranged in the fixed seat 2, both sides of the blocking plate 9 are slidably connected in the slide groove 7, a fixing ring 4 is fixedly connected to the top surface of the middle part of both sides of the slide groove 7, a connecting ring 5 is fixedly connected to the top of the fixing ring 4, a coal feeding hopper 6 is fixedly connected to the top of the connecting ring 5, an opening 10 is arranged on the blocking plate 9, and a lower coal pipe 11 is fixedly connected to the bottom of the blocking plate 9 corresponding to the opening 10.

[0024] A coal inlet hole 17 is provided on one side of the boiling furnace body 16, and a furnace door 18 is provided on the front side of the boiling furnace body 16. The output end of the cylinder 8 penetrates and slides in the middle of the rear side of the support frame 3. A fixed shaft 13 is fixedly connected to the rear side of the lower coal pipe 11, and connecting rods 12 are rotatably connected on both sides of the fixed shaft 13. Two groups of connecting rods 12 are fixedly connected with movable plates 14, so that the coal in the lower coal pipe 11 can effectively fall onto the conveying plate 15. A conveying plate 15 is fixedly connected to the top of one side of the support seat 1, and the conveying plate 15 is fixedly connected to the coal inlet hole 17 on the boiling furnace body 16. The limit plate 19 abuts against the movable plate 14, which effectively controls the opening and closing of the movable plate 14 on the lower coal pipe 11.

[0025] Working principle: when feeding carbon to the boiling furnace body 16, the coal is poured into the coal inlet hopper 6, and the coal in the coal inlet hopper 6 falls into the lower coal pipe 11 through the opening 10. The movable plate 14 at the bottom of the lower coal pipe 11 is abutted and closed by the limit plate 19, and the cylinder 8 is started. The cylinder 8 drives the blocking plate 9 to slide in the support frame 3. When the blocking plate 9 slides to one side of the support frame 3, the limit plate 19 is separated from the movable plate 14, and the movable plate 14 is opened by gravity. The coal in the lower coal pipe 11 falls onto the conveying plate 15 and slides toward the coal inlet hole 17. The coal slides into the boiling furnace body 16 through the coal inlet hole 17. When the blocking plate 9 moves on the support frame 3, the blocking plate 9 blocks the fixed ring 4 on the side away from the opening 10 to prevent the coal from falling, thereby saving a large amount of coal resources.
