DETAILED DESCRIPTION

[0037] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0038] In the present disclosure, unless otherwise specified, directional words such as "inner" and "outer" are defined with respect to the outline of the corresponding component. The use of the terms "first", "second", etc. is intended to distinguish different components and does not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0039] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, a boiler assembly is provided, which may include a boiler body 1, a ceramic insulation layer 2, a silicon material insulation layer 3 and an ash collecting trough 4. The boiler body 1 may be hollow inside to form a receiving cavity, and a first opening is provided at the bottom of the receiving cavity. The ceramic insulation layer 2 may be coated on the inner wall of the boiler body 1, and the silicon material insulation layer 3 may be coated on the side of the ceramic insulation layer 2 away from the inner wall of the boiler body 1. The ash collecting trough 4 may be provided below the first opening, and communicated with the receiving cavity through the first opening, for collecting the furnace ash in the receiving cavity.

[0040] Through the above technical solution, an opening is formed at the bottom of the boiler body 1, and an ash collecting trough 4 is provided at the opening to collect ash, thereby reducing the possibility of ash accumulation in the furnace, reducing the corrosion of the inner wall of the boiler body 1, and improving the durability of the boiler components. In addition, a ceramic insulation layer 2 and a silicon insulation layer 3 are simultaneously coated on the inner wall of the boiler body 1. Compared with a single silicon material coating, coating a ceramic insulation layer 2 between the silicon insulation layer 3 and the boiler body 1 can not only improve the corrosion resistance of the inner wall of the boiler body 1 and reduce the impact of ash on the inner wall, but also improve the high temperature resistance of the boiler body 1 and the overall strength of the coating, so that the coating is not easy to fall off, so that the boiler components can operate stably for a long time, maintenance is more convenient, and the service life of the boiler components is increased.

[0041] It should be noted that the structure of the ash collecting trough 4 and the boiler body 1 can be that the edge of the ash collecting trough 4 is connected to the edge of the first opening, so that the boiler body 1 and the ash collecting trough 4 together constitute a closed structure, or the ash collecting trough 4 is an open structure, and the boiler body 1 is set in the ash collecting trough 4, which is not limited in the present disclosure. The first opening being located at the bottom can mean that the first opening is located at the bottom surface of the boiler body 1, or it can mean that it is located at the side wall of the lower part of the boiler body 1 near the bottom surface edge, which is also not limited in the present disclosure.

[0042] Furthermore, if Figure 1As shown, the boiler body 1 may include a boiler body 11 and a boiler lower body 12. The boiler lower body 12 may be connected below the boiler body 11. The boiler lower body 12 is a gradually contracting structure, and the first opening is arranged at the bottom of the gradually contracting structure. The gradually contracting structure of the boiler lower body 12 may effectively guide the ash out of the boiler body 1, thereby reducing the possibility of the ash gathering in the boiler.

[0043] According to one embodiment of the present disclosure, Figure 1 , Figure 3 and Figure 4 As shown, the ceramic insulation layer 2 may include an oxide ceramic layer 21 and a metal ceramic layer 22, the oxide ceramic layer 21 may be coated on the inner wall of the boiler body 11, and the metal ceramic layer 22 may be coated on the inner wall of the boiler lower body 12. Both the oxide ceramic layer 21 and the metal ceramic layer 22 may make the structural strength of the coating stronger. The silicon material insulation layer 3 may include an organic silicon primer layer 31 and an organic silicon middle coating layer 32. The organic silicon primer layer 31 may be coated on the side of the ceramic insulation layer 2 away from the inner wall of the boiler body 1, and the organic silicon middle coating layer 32 may be coated on the side of the organic silicon primer layer 31 away from the ceramic insulation layer 2. The provision of a double organic silicon layer may further enhance the heat resistance and corrosion resistance of the coating, and effectively extend the service life of the boiler components.

[0044] According to one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the ash collecting trough 4 may include a bottom wall 41, a side wall 42 and a baffle 44. The boiler body 1 may be placed on the bottom wall 41, the side wall 42 is arranged at the edge of the bottom wall 41 and extends in a direction away from the bottom wall 41, and a second opening 43 is provided on the side wall 42. The baffle 44 may be arranged in the second opening 43 in an openable and closable manner, and the baffle 44 matches the shape of the second opening 43. Although the ash collecting trough 4 may be an open structure without a top wall, due to the excessive external structure of the boiler body 1, directly cleaning the ash collecting trough 4 from the upper end will be affected by the external structure of the boiler body 1, and cleaning is inconvenient. For example, the structure of the boiler bracket 50 mentioned above will affect the movement of the cleaning tool when the cleaning tool extends into the ash collecting trough 4 from the top, resulting in inadequate cleaning. Therefore, a second opening 43 is provided from the side of the ash collecting trough 4, and an openable and closable baffle 44 is provided at the second opening 43 so that the cleaning tool can be extended from the side without causing conflict with the structure of the boiler body 1 and affecting the cleaning. Regarding the connection structure between the baffle 44 and the second opening 43, the baffle 44 and the second opening 43 may be hinged by a hinge or other structure to achieve rotational opening and closing, or may be a plug-in structure as described below, which is not limited in the present disclosure.

[0045] Furthermore, if Figure 2As shown, a groove 431 may be provided at the edge of the second opening 43, and a matching block 441 matching with the groove 431 may be provided at the edge of the baffle 44, so that the baffle 44 can be pluggably arranged in the second opening 43. The baffle 44 is fixed to the side wall 42 by the matching of the groove 431 and the matching block 441. In the case where the baffle 44 is rectangular, the matching block 441 may be provided only at the lower edge of the baffle 44, and the groove 431 may also be provided only at the corresponding lower edge of the second opening 43, so that the baffle 44 can be more easily plugged in and out. The mating blocks 441 may also be arranged at the lower edge and both side edges at the same time, and grooves 431 may be arranged at the edges of the second opening 43. In this way, when the baffle 44 is inserted into the second opening 43, the grooves 431 at both sides of the second opening 43 may form a slideway structure with the mating blocks 441 at both sides of the baffle 44, which may fix the moving trajectory of the baffle 44, make the baffle 44 match the groove 431 more accurately, and increase the stability of the mating between the baffle 44 and the groove 431.

[0046] Furthermore, if Figure 2 As shown, the matching block 441 may be a structure whose thickness gradually decreases from the connection with the baffle 44 to the outside. That is, the thickness of the matching block 441 gradually decreases outward, and the shape of the groove 431 may also match the shape of the matching block 441. Compared with the matching block 441 structure with uniform thickness, the wedge-shaped structure with gradually decreasing thickness can facilitate the insertion and removal of the baffle 44 in the second opening 43.

[0047] According to one embodiment of the present disclosure, Figure 1 As shown, the boiler assembly may further include a boiler bracket 50, which may be connected to the outside of the boiler body 1 and may be placed on the bottom wall 41. The boiler bracket 50 may be a cylindrical frame structure, that is, two rings of the cylindrical frame are connected by a plurality of support rods arranged at intervals, one ring is connected to the outside of the boiler body 1, and the other ring is placed on the bottom wall 41 for support. It may also be a support structure composed of a plurality of rod-shaped bodies, which is not limited in the present disclosure. The boiler bracket 50 may serve as an extension of the boiler body 1, so that the boiler body 1 is supported more stably in the ash collecting trough 4, thereby improving the overall structural strength of the boiler assembly.

[0048] Furthermore, if Figure 1 and Figure 2As shown, the bottom wall 41 can also be provided with a first magnetic block 51, and a second magnetic block 52 that magnetically cooperates with the first magnetic block 51 can be provided on one side of the boiler support 50 near the bottom of the ash collecting trough 4. The second magnetic block 52 can be magnetically adsorbed with the first magnetic block 51, so that the boiler support 50 is fixed more firmly. Both the first magnetic block 51 and the second magnetic block 52 can be multiple and spaced, and the present disclosure does not limit this. In addition, since the ash produced in the boiler has a certain iron content, the first magnetic block 51 and the second magnetic block 52 also have a certain adsorption function for the ash, which is convenient for gathering the ash and is conducive to cleaning the ash collecting trough 4, so that the cleaning of the ash collecting trough 4 is more in place. In addition, a mosaic groove that cooperates with the first magnetic block 51 is opened on one side of the bottom wall 41 near the boiler body 1, and the first magnetic block 51 is arranged in the mosaic groove, and the surface of the first magnetic block 51 near the boiler body 1 and the surface of the bottom wall 41 near the boiler body 1 are located on the same horizontal line. In this way, the upper surface of the first magnetic block 51 can be flush with the upper surface of the bottom wall 41 after installation, thereby reducing the generation of cleaning dead corners.

[0049] According to one embodiment of the present disclosure, Figure 1 As shown, the boiler assembly may further include a pulverized coal bin 6, a main pulverized coal blowing path 7, and a pulverized coal blowing branch path 71. One end of the main pulverized coal blowing path 7 is connected to the boiler body 1, and the other end is connected to a fan for directing air into the boiler body 1. The fan can blow the gas in the main pulverized coal blowing path 7 into the boiler body 1. The two ends of the pulverized coal blowing branch path 71 are respectively connected to the pulverized coal bin 6 and the main pulverized coal blowing path 7, and the pulverized coal blowing branch path 71 is located between the fan and the boiler body 1. When the pulverized coal in the pulverized coal bin 6 is transported to the main pulverized coal blowing path 7 via the pulverized coal blowing branch path 71, the pulverized coal can be blown into the boiler body 1 through the pulverized coal blowing branch path 71. One end of the pulverized coal blowing branch path 71 is connected to the upper side of the main pulverized coal blowing path 7, and the other end extends to the upper side of the main pulverized coal blowing path 7, so that the pulverized coal in the pulverized coal bin 6 can slide from the pulverized coal blowing branch path 71 to the main pulverized coal blowing path 7 under the action of gravity.

[0050] In addition, it should be noted that the boiler assembly may further include a serpentine pipe 8, which may be connected to the top of the boiler body 1, thereby improving the heat exchange efficiency and ensuring the efficient operation of the boiler assembly.
