Description

Technical Field

[0001] This invention relates to the field of steam boiler technology, specifically a water-circulating steam boiler. Background Technology

[0002] A steam boiler is a device that heats water to boiling point to produce steam. Steam, as an energy carrier, is widely used in various fields such as industrial production and domestic heating. Working principle of a steam boiler: Fuel combustion: Boilers generate heat by burning fuel; Water heating: Heat is transferred to the water inside the boiler, causing the water to heat up; Water boiling: When the water temperature rises to the boiling point, the water begins to boil and produce steam; Steam output: The generated steam is delivered to equipment that needs to use steam through steam pipelines; In the working principle of the steam boiler described above, the steam boiler needs to use fuel in the process of heating water. The fuel is burned to heat the water. There are many types of fuels that can be selected, such as coal, wood, and biomass pellets. However, during the heating process of a steam boiler, especially when using fuels such as wood and coal, solid impurities such as charcoal and coal ash are produced after the combustion of these fuels. If these impurities accumulate inside the boiler, they will fill the pores between the wood and coal during subsequent use of the steam boiler, reducing the oxygen content between the wood and coal. This will lead to incomplete combustion of the wood and coal, reduced heat utilization efficiency, and consequently, a decline in the performance of the steam boiler.

[0015] Example 1: like Figures 1 to 10 As shown; a water-circulating steam boiler includes a boiler body; the boiler body includes a combustion chamber 1, an evaporation chamber 2, and a water supply chamber 3.

The first connecting pipe 32, the second connecting pipe 33, the third connecting pipe 34, the first vent pipe 35, and the second vent pipe 36 are located on the same side; The lower ends of the combustion chamber 1, evaporation chamber 2 and water supply chamber 3 are provided with a base 7. The middle part of the base 7 is hollow. Multiple ventilation holes 71 are opened on the side of the base 7. The lower ends of the evaporation chamber 2 and water supply chamber 3 are closed to the middle part of the base 7. The lower end of the combustion chamber 1 is connected to the middle part of the base 7. The end of the combustion chamber 1 away from the evaporation chamber 2 is provided with a discharge port 11. The lower end of the combustion chamber 1 is provided with a ash removal component 8, which is used to clean the combustion chamber 1. The dust removal component 8 includes; Plate 81 and Plate 82 are disposed at the lower end of the combustion chamber 1, with the opening at the lower end of the combustion chamber 1 located between Plate 81 and Plate 82. Plate 81 is located at the lower end of the side of the combustion chamber 1 away from the evaporation chamber 2. An adjustment groove 83 is provided in the middle of the lower end of both Plate 81 and Plate 82. Plate 81 and Plate 82 are located inside the cavity in the middle of the base 7. A fixing post 72 is provided inside the cavity of the base 7. The fixing post 72 is located in the middle of the first plate 81 and the second plate 82. A first hinge plate 73 and a second hinge plate 74 are rotatably connected to the fixing post 72. A first telescopic plate 731 is slidably connected to the first hinge plate 73 and the end away from the second hinge plate 74. A second telescopic plate 741 is slidably connected to the end of the second hinge plate 74 away from the first hinge plate 73. A blocking block 732 is provided at the upper end of the first hinge plate 73 near the second hinge plate 74. The lower end of the first plate 81 is slidably connected to the first slide plate 84. The first slide plate 84 is provided with a first hinge block 841 on the side near the second plate 82. The end of the first telescopic plate 731 away from the first hinge plate 73 is hinged to the first hinge block 841. The lower end of the second plate 82 is slidably connected to a rectangular frame 821. In the initial state, the rectangular frame 821 is located inside the adjustment groove 83 at the lower end of the second plate 82. A second hinge block 822 is provided on the side of the lower end of the rectangular frame 821 that is close to the first plate 81. The end of the second telescopic plate 741 that is away from the first hinge plate 73 is hinged to the second hinge block 822. A drive plate 86 is provided on the lower end of the first slide plate 84 away from the second slide plate 82. The drive plate 86 has an L-shaped structure and extends out of the base 7 on the side away from the second slide plate 82, so that the vertically downward end of the drive plate 86 is located outside the base 7. A drive groove 75 is provided on the side of the base 7. The drive plate 86 is slidably connected to the inside of the drive groove 75. A drive motor 76 is provided on the outside of the base 7. A gear is provided on the output shaft of the drive motor 76. The gear meshes with the outer side of the vertically downward end of the drive plate 86. The specific workflow is as follows; When using the steam boiler, first connect the water injection pipe 31 on one side of the lower annular pipe 5 of the water supply chamber 3 to the external water pipe. Water is then injected into the lower annular pipe 5 below the water supply chamber 3 through the water injection pipe 31. The water inside the lower annular pipe of the water supply chamber 3 flows into the evaporation pipe 6 of the water supply chamber 3, causing the water level inside the evaporation pipe 6 on the side wall of the water supply chamber 3 to rise until it reaches the upper annular pipe 4 above the water supply chamber 3. Subsequently, the water flows into the No. 1 connecting pipe 32 on one side of the upper annular pipe 4 of the water supply chamber 3. Through the No. 1 connecting pipe 32, the water flows from the upper annular pipe 4 of the water supply chamber 3 into the lower annular pipe 5 of the combustion chamber 1. Because the combustion chamber 1... The lower annular pipe 5 is connected to the lower annular pipe 5 of the evaporation chamber 2 through the second connecting pipe 33, and the lower annular pipes 5 of adjacent evaporation chambers 2 are connected through the third connecting pipe 34. So when water enters the lower annular pipe 5 below the combustion chamber 1, it will then enter the lower annular pipe 5 inside the evaporation chamber 2 through the second connecting pipe 33 and the third connecting pipe 34. As water is continuously injected into the water injection pipe 31, the water level in the lower annular pipe 5 below the combustion chamber 1 and the evaporation chamber 2 rises, and then enters the evaporation pipe 6 on the outer wall of the combustion chamber 1 and the evaporation chamber 2. The water level in the evaporation pipe 6 on the outer wall of the combustion chamber 1 and the evaporation chamber 2 rises. After water injection is complete, biomass pellet fuel can be added into the combustion chamber 1 through the discharge port 11, or the vent 71 at the bottom of the combustion chamber 1 can be opened and fuel such as wood can be added into the combustion chamber 1 through the vent 71. After the fuel enters the combustion chamber 1, it burns. The heat generated by the combustion is transferred to the walls of the combustion chamber 1. Since the walls of the combustion chamber 1 are made of evaporation tubes 6, which contain water, the heat of combustion heats the water inside the evaporation tubes 6. After the water is heated, it boils and produces steam. The steam inside the evaporation tubes 6 on the combustion chamber 1 rises and enters the upper annular pipe 4 on the combustion chamber 1. The upper annular pipe 4 on the combustion chamber 1 and the upper annular pipe 4 on the evaporation chamber 2 are connected by a first vent pipe 35, allowing steam to enter the evaporation chamber through the first vent pipe 35. Inside the evaporation chamber 2, the two evaporation chambers 2 are connected by a second vent pipe 36, so steam will enter the upper annular pipe 4 in each of the two evaporation chambers 2. Since the upper end of the upper annular pipe 4 of the evaporation chamber 2 is provided with an outlet pipe 37, the steam will flow out through the outlet pipe 37. A connecting plate 61 is provided between the evaporation pipes 6, and a through hole 62 is opened on the connecting plate 61, so that the hot gas generated by combustion in the combustion chamber 1 can enter the evaporation chamber 2 through the through hole 62, thereby heating the chamber wall of the evaporation chamber 2. This heats the water inside the evaporation pipe 6 on the evaporation chamber 2, generating steam. The steam generated after the water inside the evaporation pipe 6 on the evaporation chamber 2 is heated directly enters the upper annular pipe 4 above it, and then flows out through the outlet pipe 37 at the upper end of the upper annular pipe 4 of the evaporation chamber 2. Furthermore, a ash-cleaning assembly 8 is installed below the combustion chamber 1; a first plate 81 and a second plate 82 are installed below the combustion chamber 1, such that adjustment grooves 83 are opened at the lower ends of the first plate 81 and the second plate 82, and a first sliding plate 84 is slidably connected inside the first plate 81, and a rectangular frame 821 is slidably connected inside the adjustment groove 83 at the lower end of the second plate 82. A fixing post 72 is installed inside the base 7, located in the middle of the first plate 81 and the second plate 82. A first hinge plate 73 and a second hinge plate 74 are fitted on the fixing post 72, and a first telescopic plate 731 and a second telescopic plate 74 are slidably connected to the ends of the first hinge plate 73 and the second hinge plate 74 that are far apart from each other. 741, the end of the first telescopic plate 731 away from the second telescopic plate 741 is hinged to the first hinge block 841 on the inner side of the first plate 81, and the end of the second telescopic plate 741 away from the first telescopic plate 731 is hinged to the second hinge block 822 on the lower side of the rectangular frame 821. A drive plate 86 is provided on the side of the first sliding plate 84. The drive plate 86 is L-shaped. The vertically downward end of the drive plate 86 is located on the outer side of the base 7. A drive groove 75 is provided on the inner wall of the base 7. The drive plate 86 is slidably connected to the inside of the drive groove 75. A drive motor 76 is provided on the outer side of the base 7. A gear is provided on the output shaft of the drive motor 76. The gear meshes with the side of the drive plate 86. After combustion chamber 1 is used, the operator controls the drive motor 76 to rotate. The gear on the drive motor 76 meshes with the drive plate 86, causing the drive plate 86 to slide upward inside the drive groove 75. The drive plate 86 drives the first slide plate 84 to slide upward at the lower end of the first plate 81. The first slide plate 84 drives the first hinge block 841 to move upward. As the first hinge block 841 slides upward, it enters the sliding groove 85 opened inside the first plate 81. The sliding groove 85 satisfies the upward movement of the first hinge plate 73, causing the first hinge block 841 to drive the first hinge plate 73 to rotate clockwise. During this process, due to the first hinge block 841 and... The distance between the fixed columns 72 changes, so the first telescopic plate 731 will extend and retract inside the first hinge plate 73 to accommodate the rotation of the first hinge plate 73. When the first hinge plate 73 rotates, since the fuel is located above the first hinge plate 73 and the second hinge plate 74, the rotation of the first hinge plate 73 causes impurities such as coal dust and charcoal after combustion to move towards the position of the second hinge plate 74 until the first hinge plate 73 rotates to be parallel to the second hinge plate 74. At this time, a blocking block 732 is set at one end of the first hinge plate 73 near the second hinge plate 74, so that when the first hinge plate 73 is parallel to the second hinge plate 74, the lower end face of the blocking block 732 is parallel to the upper end face of the second hinge plate 74. Upon contact, as plate 81 continues to move upward, it causes the blocking block 732 to rotate. The blocking block 732 then presses against hinge plate 74, causing it to rotate clockwise. Since one end of hinge plate 74 is slidably connected to telescopic plate 741, and the end of telescopic plate 741 away from hinge plate 74 is hinged to hinge block 822 on the side of the rectangular block, the rotation of telescopic plate 741 causes hinge block 822 to move downward. Telescopic plate 741 extends from inside hinge plate 74, and rectangular frame 821 extends and retracts from the adjusting groove 83 below plate 82. A spring within the adjusting groove 83 inside plate 82 provides elastic tension. This allows the middle part of the rectangular frame 821 to extend from inside the second plate 82. Since the first hinge plate 73 and the second hinge plate 74 are in an inclined state, the coal ash and charcoal residues on the first hinge plate 73 and the second hinge plate 74 after combustion flow out from the space in the middle of the rectangular frame 821 and into the cavity inside the base 7. This cleans the inside of the combustion chamber 1, so that when the combustion chamber 1 is refilled with fuel, the residual coal ash and charcoal from the previous combustion will not affect the new fuel inside the combustion chamber 1, thereby improving combustion efficiency and the utilization efficiency of the steam boiler. Furthermore, by opening the other ventilation openings 71 on the base 7, it is convenient to clean the charcoal and other impurities inside the base 7. After cleaning is completed, the drive motor 76 reverses, causing the first slide plate 84 to move downwards, thus resetting all components.

[0016] Example 2: like Figures 1 to 8 As shown; a strip groove 77 is provided through the first hinge plate 73, the first telescopic plate 731, the second hinge plate 74, and the second telescopic plate 741; The first hinge block 841 is slidably connected to the side of the first slide plate 84, and the second hinge block 822 is slidably connected to the side of the rectangular frame 821. The specific workflow is as follows; By providing strip grooves 77 through the first hinge plate 73, the first telescopic plate 731, the second hinge plate 74, and the second telescopic plate 741, the permeability of the lower end of the first hinge plate 73, the first telescopic plate 731, the second hinge plate 74, and the second telescopic plate 741 is improved after the fuel is placed on them, which increases the amount of oxygen entering between the fuel and improves the combustion efficiency of the fuel. Furthermore, by slidably connecting the first hinge block 841 to the side of the first slide plate 84, and slidably connecting the second hinge block 822 to the side of the rectangular frame 821, and since both the first hinge plate 73 and the second hinge plate 74 are fitted onto the fixed post 72, the first hinge plate 73 and the second hinge plate 74 can slide on the fixed post 72. Therefore, when it is necessary to clean the surface of the first hinge plate 73 and the second hinge plate 74, the vent 71 below the combustion chamber 1 can be opened, and the first hinge plate 73 and the second hinge plate 74 can be slid out from the vent 71 below the combustion chamber 1 for cleaning, thereby improving the cleaning efficiency of their surfaces.

[0017] Example 3: like Figures 1 to 10 As shown; the connecting plate 61 has a V-shaped structure; The through holes 62 on the connecting plate 61 are staggered, so that the flow trajectory of gas between adjacent connecting plates 61 is wavy. A settling chamber 9 is provided in the area between the combustion chamber 1 and the evaporation chamber 2 and between adjacent evaporation chambers 2. The gas passes through the settling chamber 9 when it flows between the combustion chamber 1, the evaporation chamber 2 and the water supply chamber 3. The specific workflow is as follows; By making the connecting plate 61 a V-shaped structure, compared with the straight plate connecting plate 61, the V-shaped structure has a larger contact area with the air, so that the heat dissipation effect of the steam boiler is better than that of the straight plate connecting plate 61 when it is not running. Furthermore, the through holes 62 on the connecting plate 61 are staggered, and the gas flows in a wave shape between adjacent connecting plates 61. This results in a larger contact area between the gas and the adjacent connecting plates 61 and the steam pipe when the gas flows inside the combustion chamber 1, which makes the heating effect of the heated gas on the steam pipe inside the evaporation chamber 2 better, thereby improving the evaporation effect of water vapor inside the steam pipe. Furthermore, by setting a settling chamber 9 between the combustion chamber 1 and the evaporation chamber 2, and because the through holes 62 between the adjacent connecting plates 61 and the evaporation pipe 6 are staggered, the gas flow trajectory fluctuates up and down. This allows the dust and impurities generated by combustion carried by the gas to settle in the settling chamber 9 after the gas enters the chamber, thus preventing the gas from flowing between the combustion chamber 1 and the evaporation chamber 2 and resulting in higher gas cleanliness.

[0018] Example 4: like Figures 2 to 9 As shown; a connecting water pipe 12 is provided between the annular pipe below the combustion chamber 1 and the annular pipe below the evaporation chamber 2, and a water level gauge 13 is provided on the connecting water pipe 12; The specific workflow is as follows; By setting a connecting water pipe 12 between the annular pipe below the combustion chamber 1 and the annular pipe below the evaporation chamber 2, and installing a water level gauge 13 on the connecting water pipe 12, the changes in the water level inside the evaporation pipe 6 on the combustion chamber 1 and the evaporation chamber 2 can be observed through the water level gauge 13, thereby enabling more precise control of the water level.
