Technical Field

[0001] The utility model relates to the technical field of hot blast stoves, in particular to a hot blast stove which is easy to clean. Background Art

[0002] Hot blast furnace is a thermal power machine. It began to be widely used in my country in the late 1970s. It has become a replacement product for electric heat source and traditional steam power heat source in many industries. There are many varieties and series of hot blast furnaces. They are divided into manual burning and machine burning according to the coal adding method, and divided into coal, oil, gas furnaces, etc. according to the type of fuel.

[0003] During the use of the hot blast furnace, coal blocks are usually burned as raw materials, so that the heat after combustion enters the furnace body and heats the furnace body; with the long-term use of the hot blast furnace, thicker dirt usually appears on the inner wall of the hot blast furnace. In severe cases, it will affect the normal use of the hot blast furnace, and the dirt on the inner wall of the hot blast furnace needs to be cleaned regularly; however, the current cleaning structure in the hot blast furnace is relatively simple and only plays a cleaning role. The cleaned dirt falls downward to the corner of the bottom of the hot blast furnace due to gravity, and the staff is required to perform secondary cleaning on the fallen dirt, which brings inconvenience to the staff.

[0004] Therefore, we propose a hot blast stove that is easy to clean, so as to solve the above-mentioned problems. Utility Model Content

[0009] Furthermore, the top of the collecting box is fixedly connected to the same mounting ring through a plurality of connecting rods, and the mounting ring is connected to the "ring-shaped" movable frame by means of threads.

[0010] Furthermore, there are multiple scrapers, and a certain gap is left between adjacent scrapers.

[0011] Furthermore, a smoke exhaust port is provided on the top of the furnace body.

[0012] Beneficial effects of the utility model:

[0013] The utility model is provided with a scraper on the outer surface of the "ring-shaped" movable frame. In the process of the "ring-shaped" movable frame driving the scraper to move up and down, the scraper can clean the dirt on the inner wall of the furnace body; a collecting box is provided at the lower part of the "ring-shaped" movable frame, so that the cleaned dirt can directly fall into the collecting box, avoiding the cleaned dirt from falling into the furnace body again, reducing the cleaning process of the staff, and thus providing convenience for the staff.

[0020] 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 belong to the scope of protection of the utility model.

[0021] A hot blast furnace that is easy to clean comprises a furnace body 1, wherein an air inlet is arranged at the bottom of the furnace body 1, through which heat can enter the furnace body 1 and heat the furnace body 1, and a smoke exhaust port 15 is arranged at the top of the furnace body 1, through which smoke in the furnace body 1 can be discharged from the smoke exhaust port 15; a cleaning port 7 is arranged at the lower part of the furnace body 1, and a sealing plate 8 is placed in the cleaning port 7, it should be noted that: the sealing plate 8 is semicircular, and second mounting seats 10 are fixed at both ends of the sealing plate 8, and a first mounting seat 9 is symmetrically fixed on the outer surface of the furnace body 1, it should be noted that: the first mounting seat 9 is arranged close to the end of the cleaning port 7, and when the sealing plate 8 is installed inside the cleaning port 7, the first mounting seat 9 and the second mounting seat 10 that fit together are connected by bolts 11, thereby playing a role in fastening the sealing plate 8.

[0022] A heating tube 2 is arranged inside the furnace body 1. It should be noted that the heating tube 2 is located above the cleaning port 7. Through the arrangement of the heating tube 2, the outside air can enter the furnace body 1 for heat exchange treatment. It should be noted that the heating tube 2 is arranged in a "spiral" shape, which can increase the heat exchange area and improve the heat exchange effect. The input and output ends of the heating tube 2 extend to the outside of the furnace body 1 respectively and are fixed with flanges 16. The arrangement of the flange 16 plays a role in fixing the pipeline to the outside.

[0023] An electric telescopic rod 3 is installed on the top of the furnace body 1. The number of electric telescopic rods 3 is one. Of course, multiple electric telescopic rods 3 can also be installed according to user needs, and the telescopic end of the electric telescopic rod 3 extends to the interior of the furnace body 1 and is installed with a "ring-shaped" moving frame 5, and the outer surface of the "ring-shaped" moving frame 5 is fixed with a number of scrapers 6 at equal intervals in an inclined form, and a certain gap is left between adjacent scrapers 6, so that when the scraper 6 moves upward and cleans the dirt on the inner wall of the furnace body 1, the cleaned dirt can flow downward along the slope of the scraper 6, so that when the scraper 6 moves downward and cleans the dirt on the inner wall of the furnace body 1, the cleaned dirt can fall directly downward, thereby playing a role in cleaning the dirt on the inner wall of the furnace body 1.

[0024] A collecting box 12 is provided at the lower part of the "ring-shaped" movable frame 5. It should be noted that the collecting box 12 is also in a "ring" shape, and the outer surface of the collecting box 12 is in contact with the inner wall of the furnace body 1. Through the setting of the collecting box 12, it plays a role in collecting the dirt after cleaning, and reduces the dirt from falling into the interior of the furnace body 1, thereby facilitating the cleaning of the furnace body 1, and a plurality of connecting rods 13 are fixed to the top of the collecting box 12 along the circumferential direction, and the connecting rods 13 are fixedly connected to the same mounting ring 14, and the mounting ring 14 is threadedly connected to the inner wall of the "ring-shaped" movable frame 5, thereby playing a role in disassembling and installing the collecting box 12.

[0025] During use, a heating furnace can be installed under the furnace body 1 (the heating furnace is already a prior art and will not be described in detail in this application); after the coal blocks are burned in the heating furnace, the heat in the heating furnace can enter the furnace body 1, and then the gas pipeline that needs heat exchange is connected to the heating tube 2, so that after the gas enters the interior of the heating tube 2, the heat in the furnace body 1 can be used to exchange heat with the gas in the heating tube 2, so that after the gas heat exchange is completed, it can be discharged from the heating tube 2.

[0026] With the long-term use of the furnace body 1, a large amount of dirt will inevitably be generated on the inner wall of the furnace body 1. At this time, the electric telescopic rod 3 can be opened, and the telescopic shaft of the electric telescopic rod 3 can drive the "annular" moving frame 5 to move downward, and the dirt on the inner wall of the furnace body 1 is cleaned by the scraper 6 on the outer surface of the "annular" moving frame 5, and the cleaned dirt can fall directly into the collection box 12. After the dirt in the furnace body 1 is cleaned, the telescopic end of the electric telescopic rod 3 is extended to the longest and drives the "annular" moving frame 5 and the collection box 12 to move downward. If the collection box 12 is moved to be opposite to the cleaning port 7, the sealing plate 8 can be opened from the furnace body 1, and then the collection box 12 can be taken out from the bottom of the "annular" moving frame 5, and the dirt in the collection box 12 can be processed.
