Description

Technical Field

[0001] The utility model relates to the technical field of combustion devices, in particular to a combustion device capable of full combustion. Background Art

[0002] Adding coal to the wet sand for cast iron can prevent sand adhesion defects on the surface of the casting, improve the surface finish of the casting, reduce sand inclusion defects, and improve the collapse function of the sand. For wet ductile iron parts, it can also effectively prevent the formation of subcutaneous pores. A circular vortex burner can be used without preheating the air.

[0003] In the existing coal-fired combustion device, coal is piled up at the bottom and the coal is not burned completely, which leads to waste of coal, low combustion efficiency and affected work efficiency.

[0004] When the coal-fired combustion device is in operation, it is inevitable that slagging will occur. The ash will stick to the heating surface and the furnace wall grate under high temperature. As time goes by, it will accumulate more and more. The slagging will reduce the heat absorption of the heating surface. If the combustion device is to achieve the desired effect, the combustion must be increased, resulting in a waste of fuel. At the same time, incomplete combustion of coal will also cause waste.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] First, the utility model can avoid coal ash accumulation by arranging a driving motor and a dispersing shaft. The driving motor drives the dispersing shaft to rotate through the output shaft, and the rotation of the dispersing shaft drives the coal to move, thereby avoiding the accumulation of coal in the box, improving the combustion efficiency of the coal, and thus improving work efficiency.

[0014] Second, the utility model can avoid the accumulation of ash on the inner wall of the box by arranging a scraping mechanism and a box body.

During combustion, the driving motor 5 drives the stirring shaft 10 to rotate through the output shaft, and the rotation of the stirring shaft 10 drives the coal to move, so as to avoid the coal accumulation in the box body 1, thereby improving the combustion efficiency of the coal. At the same time, the heat is collected and utilized by the heat exchanger 4. When the combustion is completed, the baffle 7 is pulled out by manpower, so that the burned coal is discharged through the ash discharge chute 9, and the inner wall of the box body 1 is cleaned by the scraping mechanism 8 to avoid slagging which will reduce the heat absorption of the heating surface.

[0022] Specifically, the scraping mechanism 8 includes a reciprocating motor 6, which is fixedly mounted on one side of the box body 1, and one end of the reciprocating motor 6 is connected to a bidirectional threaded rod 11 through an output shaft.

[0023] Through the above technical solution, the reciprocating motor 6 drives the bidirectional threaded rod 11 to rotate through the output shaft.

[0024] Specifically, the two ends of the bidirectional threaded rod 11 are respectively connected with the first scraper 12 and the second scraper 13 through threads, and the first scraper 12 and the second scraper 13 are respectively connected to the bidirectional threaded rod 11 in forward and reverse threads.

[0025] Through the above technical solution, since the threads at both ends of the bidirectional threaded rod 11 are in opposite directions, the first scraper 12 and the second scraper 13 are moved inward at the same time by rotating the threads in opposite directions. When the first scraper 12 and the second scraper 13 move inward, they are in close contact with the inner wall of the box body 1 to scrape off the ash attached to the inner wall of the box body 1.

[0026] Specifically, the middle of the bidirectional threaded rod 11 is connected to a limiting block 14 via a bearing.

[0027] Through the above technical solution, the bidirectional threaded rod 11 is connected to the limit block 14 through a bearing in the middle, which prevents the first scraper 12 and the second scraper 13 from moving inward and contacting the dispersing shaft 10 due to the lack of obstacles, thereby causing the dispersing shaft 10 to contact the first scraper 12 and the second scraper 13 when rotating and cause damage.

[0028] Specifically, the ends of the first scraper 12 and the second scraper 13 away from the bidirectional threaded rod 11 are movably connected with an optical axis guide rail 15 , and the optical axis guide rail 15 is fixedly installed in the box body 1 .

[0029] Through the above technical solution, the movable range of the first scraper 12 and the second scraper 13 is limited by the optical axis guide rail 15 .

[0030] Specifically, a plurality of legs 16 are fixedly mounted on the bottom end of the box body 1 .

[0031] Through the above technical solution, the legs 16 abut against the ground to provide support force for the box body 1.

[0032] When in use, the coal is added into the box body 1 from the feed port 2 by manpower with the help of tools, and the coal is ignited by the igniter 3 at this time. During combustion, the driving motor 5 drives the stirring shaft 10 to rotate through the output shaft, and the rotation of the stirring shaft 10 drives the coal to move, so as to avoid the coal from piling up in one place in the box body 1 and improve the combustion efficiency of the coal. At the same time, the heat is collected and utilized by the heat exchanger 4. When the combustion is completed, the baffle 7 is pulled out by manpower to discharge the burned coal through the ash discharge chute 9. When the inside of the box body 1 needs to be cleaned, the reciprocating motor 6 drives the bidirectional threaded rod 11 to rotate through the output shaft. Because the threads at both ends of the bidirectional threaded rod 11 are in opposite directions, the opposite The first scraper 12 and the second scraper 13 are moved inwardly at the same time by rotating the thread in the direction. When the first scraper 12 and the second scraper 13 move inwardly, they are in close contact with the inner wall of the box body 1 to scrape off the ash attached to the inner wall of the box body 1. The cleaning is completed by scraping off the ash on the inner wall of the box body 1, and the scraped ash is pushed toward the ash unloading chute 9 to avoid slagging which will reduce the heat absorption of the heated surface. At the same time, the two-way threaded rod 11 is connected to a limiting block 14 by a bearing in the middle to prevent the first scraper 12 and the second scraper 13 from moving inwardly without any obstacles and contacting the dispersing shaft 10, which may cause the dispersing shaft 10 to contact the first scraper 12 and the second scraper 13 when it rotates and cause damage.
