Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and in particular to a self-cleaning boiler core. Background Technology

[0002] Existing boiler cores are designed to provide a specific space for fuel combustion. Within this relatively enclosed space, fuel (such as coal) is thoroughly mixed with air and ignited to undergo a vigorous oxidation reaction, releasing a large amount of heat energy.

[0003] However, it does not have a self-cleaning function. After combustion, if the traditional furnace core adopts the natural settling method, the waste needs to stay for a long time to completely settle to the bottom of the furnace. After that, it still needs to be cleaned manually. The manual cleaning process is cumbersome, requiring opening the furnace door and entering the furnace to operate. The whole process takes a long time and reduces the operating efficiency of the boiler. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a self-cleaning boiler core. After combustion, the extrusion plate is inserted into the combustion chamber. The combustion waste on the placement plate can be quickly and repeatedly shaken by an electric push rod and a spring, which can accelerate the separation process of combustion waste from the placement plate. Compared with the traditional natural settling or manual cleaning method, the cleaning time is shortened. Smaller waste will fall directly from the screen holes, while larger waste will come into contact with the crushing cone on the extrusion plate during the shaking and be collided into smaller particles before falling from the screen holes. This ensures that the waste can pass through the screen holes quickly and completely for cleaning. The fallen waste will enter the semi-pipe along the feed plate and be pushed out by the auger, which speeds up the cleaning process.

[0005] This utility model also provides a boiler core with the aforementioned self-cleaning function, comprising: a combustion chamber, a heating tank fixedly connected to the upper surface of the combustion chamber, a flue pipe connected to the upper surface of the combustion chamber, a fuel inlet provided on the combustion chamber, two through holes provided on the combustion chamber, a sliding groove provided on the two opposite inner surfaces of the through holes, a sliding plate slidably connected to the inner surface of the sliding groove, a placement plate fixedly connected between the two sliding plates, a plurality of sieve holes provided on the placement plate, and a movable side plate fixedly connected to the opposite side surfaces of the two sliding plates. The combustion chamber has stationary side plates fixedly connected to its two side surfaces. A spring is fixedly connected between the moving side plate and the stationary side plate. An electric push rod is fixedly connected between the moving side plate and the stationary side plate. The combustion chamber has a second sliding groove. An extrusion plate is movably connected to the inner surface of the second sliding groove. A crushing cone is fixedly connected to the lower surface of the extrusion plate. Two feeding plates are fixedly connected to the inner surface of the combustion chamber. A half-pipe is fixedly connected between the two feeding plates. An auger is rotatably connected to the inner surface of the half-pipe. The combustion chamber has an ash discharge hole that communicates with the half-pipe.

[0006] According to the present invention, a self-cleaning boiler core is provided, wherein a motor is fixedly connected to the front surface of the combustion chamber, and the auger is driven by the motor.

[0007] According to the present invention, a self-cleaning boiler core is provided, wherein a sealing cover is movably connected to the front surface of the fuel inlet, and a handle is fixedly connected to the front surface of the sealing cover.

[0008] According to the present invention, a self-cleaning boiler core is provided, wherein a locking block is fixedly connected to the rear surface of the sealing cover, and the locking block is movably connected to the inner wall of the fuel inlet.

[0009] According to the present invention, a self-cleaning boiler core is provided, wherein a frame is connected through the sealing cover, and heat-resistant glass is fixedly connected to the inner wall of the frame.

[0010] According to the present invention, a self-cleaning boiler core is provided, wherein a connecting block is fixedly connected to the front surface of the combustion chamber, and the connecting block is located on both sides of the sealing cover.

[0011] According to the present invention, a self-cleaning boiler core is provided, wherein both the connecting block and the sealing cover are provided with insertion holes, and the inner surface of the insertion hole is movably connected with a pin.

[0012] Compared with existing technologies, this self-cleaning boiler core inserts an extrusion plate into the combustion chamber after combustion. An electric push rod, combined with a spring, quickly and repeatedly agitates the combustion waste on the plate, accelerating the separation of the waste from the plate. Compared to traditional natural settling or manual cleaning methods, this shortens the cleaning time. Smaller waste pieces fall directly through the screen holes, while larger pieces are crushed into smaller particles by contacting the crushing cone on the extrusion plate during agitation before falling through the screen holes. This ensures that the waste passes through the screen quickly and completely for cleaning. The fallen waste then enters the semi-pipe along the feed plate and is pushed out by the auger, further accelerating the cleaning process. Attached Figure Description

[0027] Working principle: Before use, the operator holds handle 2 to open the sealing cover 1, removes the extrusion plate 15 from the combustion chamber 8, and then puts fuel (such as coal) into the combustion chamber 8 through the fuel inlet 13. The fuel comes into full contact with the air in the combustion chamber 8 and undergoes a vigorous oxidation reaction to release heat energy. The heating tank 7 is connected to the upper surface of the combustion chamber 8 and can receive the heat generated by combustion for heating water or other media. The exhaust pipe 6 discharges the flue gas generated by combustion. After combustion, the extrusion plate 15 is inserted into the slide groove 28 on the combustion chamber 8, and the electric push rod 11 starts to work, which, together with the spring 22, makes the placement plate 17 quickly and repeatedly bounce. The placement plate 17 is installed in the combustion chamber 8 through the cooperation of the moving side plate 21, the sliding plate 27 and the chute 26, and can slide stably. During the shaking process, smaller wastes fall directly from the screen holes 18 of the placement plate 17, while larger wastes collide with the crushing cone 16 on the extrusion plate 15 during the shaking process. They are then crushed into smaller particles and fall from the screen holes 18. The fallen wastes enter the half-pipe 14 along the feed plate 25. The motor 5 drives the auger 20 to rotate. The auger 20 rotates in the half-pipe 14 and pushes the wastes from one end of the half-pipe 14 to the ash discharge hole 19, and finally discharges them from the combustion chamber 8, completing the entire process of cleaning up the combustion waste.
