[0034] A steam boiler according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the utility model aims to provide an embodiment of a steam boiler.

[0036] In this embodiment, a steam boiler mainly includes a furnace body 100 and a feeding mechanism.

[0037] The furnace body 100 is used for heating and outputting steam. A fuel inlet 110 is provided at the top of one side of the furnace body 100 , so as to facilitate the delivery of biomass into the furnace body 100 through the fuel inlet 110 .

[0038] As for the loading mechanism, the loading mechanism is located on the side of the furnace body 100 close to the fuel inlet, and the loading mechanism includes an upright bracket 120, a hopper 130 and a drive assembly 140. The bracket 120 is provided with a guide rail 150 extending from bottom to top, and the hopper 130 cooperates with the guide rail 150 for guidance. The drive assembly 140 is used to drive the hopper 130 to lift and load.

[0039] It can be understood that the bracket 120 is arranged upright, and the guide rail 150 on the bracket 120 extends from bottom to top, and the biomass is loaded and transported upward through the hopper 130. The biomass on the hopper 130 will not slip or fall due to the excessive inclination angle between the guide rail 150 and the horizontal plane, so that the hopper 130 can transport the biomass from bottom to top along the guide rail 150 to the fuel inlet 110, thereby increasing the inclination angle between the guide rail 150 and the horizontal plane, and further, reducing the footprint of the loading mechanism, which is conducive to saving space.

[0040] The hopper 130 has two coaxially arranged first guide members 160 and two coaxially arranged second guide members 170, the two first guide members 160 are respectively arranged on both sides of the hopper 130, and the two second guide members 170 are respectively arranged on both sides of the hopper 130, the first guide member 160 is located above the second guide member 170, and the bracket 120 is provided with two guide rails 150, and one guide rail 150 cooperates with the first guide member 160 and the second guide member 170 on the same side of the hopper 130 to guide.

[0041] It is understandable that the first guide member 160 and the second guide member 170 on the same side of the hopper 130 can cooperate with a guide rail 150 for guidance at the same time, so that the guide rail 150 can limit the angle of the hopper 130 to prevent the hopper 130 from tilting or swinging after being loaded with biomass, causing the biomass in the hopper 130 to fall.

[0042] The top end of the guide rail 150 has a lifting guide portion 180 and a dumping guide portion 190, and the dumping guide portion 190 includes a first arc segment 200 and a second arc segment 210. The first arc segment 200 is located on the side of the second arc segment 210 close to the fuel inlet 110. One end of the first arc segment 200 and one end of the second arc segment 210 are both connected to the top end of the lifting guide portion 180. The other end of the first arc segment 200 extends toward the direction close to the fuel inlet 110 and has a first limiting baffle 220. The first arc segment 200 cooperates with the first guide member 160 for guidance, the first limiting baffle 220 is used to limit the first guide member 160, and the second arc segment 210 extends in an arc shape toward the direction close to the fuel inlet 110 with the axis of the first guide member 160 as the center when the first guide member 160 and the first limiting baffle 220 are abutted for limitation. The second arc segment 210 cooperates with the second guide member 170 for guidance, and the first arc segment 200 and the second arc segment 210 cooperate to guide the hopper 130 to flip and dump materials toward the fuel inlet 110.

[0043] It can be understood that when the driving assembly 140 drives the hopper 130 to lift, the first guide member 160 reaches the top of the lifting guide part 180 and then enters the first arc segment 200. When the first wire member moves to the first limit baffle 220, the first limit baffle 220 limits the first guide member 160, so that the first arc segment 200 can guide the bucket mouth of the hopper 130 to be located above the fuel inlet 110. At this time, the second guide member 170 reaches the top of the lifting guide part 180 and enters the second arc segment 210 and continues to move along the second arc segment 210, so that the hopper 130 can swing along the first guide member 160, and then the hopper 130 flips over to pour the biomass into the fuel inlet 110, making the lifting and pouring actions of the hopper 130 more coherent and smooth.

[0044] In some specific embodiments, the lifting guide portion 180 is arranged upright, thereby further reducing the floor space occupied by the loading mechanism and facilitating space saving.

[0045] In some specific embodiments, the second arc segment 210 has a second limiting baffle 230 at one end away from the lifting guide portion 180. The second limiting baffle 230 is used to limit the second guide member 170, thereby facilitating the limitation of the flipping angle of the hopper 130 and preventing the hopper 130 from flipping at an excessively large angle.

[0046] In some specific embodiments, the first guide member 160 is configured as a roller, and the first guide member 160 rolls within the guide rail 150, thereby reducing the friction resistance between the first guide member 160 and the guide rail 150, thereby making the lifting of the hopper 130 more labor-saving.

[0047] In some specific embodiments, the second guide member 170 is configured as a roller, and the second guide member 170 rolls within the guide rail 150, thereby reducing the friction resistance between the second guide member 170 and the guide rail 150, thereby making the lifting of the hopper 130 more labor-saving.

[0048] In some specific embodiments, the hopper 130 is hinged with a swing arm 240, and the hinge center of the swing arm 240 and the hopper 130 is located at the bottom of the hopper 130 and on the side of the line connecting the axis of the first guide member 160 and the axis of the second guide member 170 away from the furnace body 100, and the drive assembly 140 is connected to the free end of the swing arm 240.

[0049] It can be understood that the hinge center of the swing arm 240 and the hopper 130 is located at the bottom of the hopper 130 and on the side of the line connecting the axis of the first guide member 160 and the axis of the second guide member 170 away from the furnace body 100. When the first guide member 160 is lifted to the top of the lifting guide part 180, the gravity of the hopper 130 itself can drive the hopper 130 to tilt in the direction close to the furnace body 100, so that the first guide member 160 can automatically enter the first arc segment 200, avoiding the first guide member 160 from being stuck between the first arc segment 200 and the second arc segment 210.

[0050] Furthermore, the swing arm 240 includes two arm bodies 250 and a connecting rod 260. The bottom ends of the two arm bodies 250 are hinged to the two sides of the hopper 130 respectively. The connecting rod 260 connects the free ends of the two arm bodies 250. The drive assembly 140 is connected to the connecting rod 260, thereby making the support of the swing arm 240 to the hopper 130 more balanced.

[0051] In some specific embodiments, the driving assembly 140 includes a rope reel 270 rotatably arranged on the bracket 120, a rope 280 connected to the rope reel 270, and a first motor 290 that drives the rope reel 270 to rotate. The rope reel 270 rotates to reel in the rope 280 so that the rope 280 drives the hopper 130 to lift, and the rope reel 270 rotates in the opposite direction to unreel the rope 280 so that the hopper 130 descends, thereby making the structure of the driving assembly 140 simple and easy to manufacture.

[0052] Furthermore, two suspension ropes 280 are provided, and two rope reels 270 are provided correspondingly, thereby making the support of the drive assembly 140 to the hopper 130 more balanced.

[0053] In some specific embodiments, the inner wall of the hopper 130 is provided with a capacity scale 300, so as to facilitate observation and judgment of the amount of biomass added to the hopper 130 each time, and further facilitate control of the amount of fuel added each time, so that the amount of fuel added each time is more uniform.

[0054] In some specific embodiments, the opening of the hopper 130 is tilted downwardly away from the furnace body 100 , thereby facilitating pouring the biomass into the hopper 130 from the side of the opening of the hopper 130 away from the furnace body 100 .

[0055] Throughout this specification, references to terms such as "one embodiment, some embodiments, exemplary embodiments, examples, specific examples, or some examples" indicate that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, illustrative uses of these terms do not necessarily refer to the same embodiment or example.

[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
