Description

Technical Field

[0001] The invention relates to the field of drying furnaces, in particular to a drying furnace based on integrated coal combustion. Background Art

[0002] A coal-fired drying furnace is a type of drying equipment that uses coal as a heat source. It is mainly used to dry materials by evaporating moisture at high temperatures. It usually adopts a drum design, heats the air through a hot air furnace, and then sends the hot air into the drying drum under the action of the air supply system, directly exchanging heat with the high-humidity material, strongly evaporating moisture to achieve the purpose of drying.

[0003] A coal-fired drying furnace is usually composed of a combustion furnace and a drum dryer. When drying materials, the materials need to be fed into the drum first, and high-temperature hot air is fed into the drum to dry the materials. Existing Chinese public patent document: CN118376052B discloses a drying converter, in which the position of the slider is positioned by the number of turns of the traction rope wound around the winding wheel. The greater the distance the slider moves, the greater the distance the push plate pushes the annular plate to move. Later, when the block pops out and is inserted into the arc groove, the collar needs to drive the annular plate to rotate a larger angle to prompt one end of the insertion rod to move out of the insertion hole, and multiple notches are spirally distributed on the guide tube. Therefore, through the above structure According to the different positions of the slider, the slot corresponding to the slider can rotate with the guide pipe to the vicinity of the through slot, so as to clean the material adhered to the inner wall of the furnace body. Through this structure, the inner wall of the furnace body can be inspected, which is beneficial to clean the material adhered to the inner wall of the furnace body, thereby avoiding fire. Although it can solve the problem of material sticking in the furnace body, when the material is fed into the drum, due to the high humidity between the materials, the material will accumulate inside the drum, making it difficult for the material in the middle position to be dried in the first time when the drum is drying the material, so that the drying rate of the material close to the drum is higher than that of the material in the middle position, which is prone to uneven drying, affecting the production quality of the material.

Two equidistantly distributed positioning shafts 27 are rotatably mounted on the outer side of the drying cylinder 5. The inner side of the mounting cylinder 1 Two symmetrically distributed annular sleeves 28 are fixedly installed, and the outer side of the positioning shaft 27 is rotatably installed on the inner side of the annular sleeve 28 to provide support for the drying cylinder 5 and improve the stability of the rotation of the drying cylinder 5; it also includes: a drying mechanism, which is used to make the mounting cylinder 1 dry the material evenly, and the drying mechanism is installed on the inner side of the mounting cylinder 1; a scraping mechanism, which is used to dry materials with more particle sizes in the mounting cylinder 1, and the scraping mechanism is installed between the two mounting plates 2; a dredging mechanism, which is used to ensure the normal discharge of materials in the feed pipe 4, and the dredging mechanism is installed on the inner side of the feed pipe 4.

[0022] The drying mechanism includes a drying cylinder 5 rotatably installed between two mounting plates 2, a gear ring 6 is fixedly installed on the outer side of the drying cylinder 5, a positioning frame 7 is fixedly installed on the outer side of the mounting plate 2 located on the right side of the mounting cylinder 1, a motor 8 is fixedly installed on the outer side of the positioning frame 7, a convex plate rotatably installed on the output end of the power supply machine 8 is provided on the outer side of the mounting cylinder 1, a gear 9 matched with the gear ring 6 is fixedly installed on the output end of the motor 8, so that the motor 8 drives the drying cylinder 5 to rotate through the gear 9 and the gear ring 6, a circular box 10 is rotatably installed on the corresponding side of the two mounting plates 2, a positioning cylinder 19 is fixedly installed between the two circular boxes 10, four mounting rods 11 distributed symmetrically with respect to the center are arranged between the two circular boxes 10, and a plurality of equidistantly distributed mounting rods 11 are arranged on the outer side of the mounting rods 11 The material-scraping plate 12 is used to scoop up the materials to achieve uniform drying of the materials. The material-scraping plate 12 is in an inclined structure, which is convenient for pushing the dried materials. The material-scraping plates 12 on the four mounting rods 11 are staggered, which is convenient for comprehensively scooping up the materials in the drying cylinder 5, and the materials are quickly separated by the unloading of the materials and the pushing of the material-scraping plates 12. A rotating cylinder 13 is fixedly installed on the outside of the circular box 10 on the right side of the mounting cylinder 1. A synchronous belt 14 is rotatably installed between the outside of the rotating cylinder 13 and the output end of the motor 8, so that the rotation direction of the material-scraping plate 12 is opposite to that of the drying cylinder 5, which is convenient for quickly scooping up the materials. A discharging cylinder 26 is fixedly installed on the outside of the mounting plate 2 on the left side of the mounting cylinder 1. The discharging cylinder 26 is located below the coal-fired furnace 3 and is used to discharge the materials after drying. The motor 8 can drive the gear ring 6 to rotate through the gear 9, so that the gear ring 6 drives the drying cylinder 5 to rotate between the two mounting plates 2, which can drive the material in the drying cylinder 5 to roll. At the same time, the motor 8 can drive the rotating drum 13 to rotate through the synchronous belt 14, so that the rotating drum 13 drives the four mounting rods 11 to rotate synchronously through the circular box 10. Since the rotation direction of the drying cylinder 5 is opposite to that of the circular box 10, the mounting rod 11 can scoop up the material in the drying cylinder 5 through the scooping plate 12, and the gap between the scooping plates 12 is used to quickly separate the material. The scooping plates 12 on the four mounting rods 11 are staggered, so that the material in the drying cylinder 5 can be repeatedly scooped up. When the material falls, the material can be quickly dried. The scooping plates 12 with an inclined structure can gradually transport the material to the discharge cylinder 26, which is convenient for discharging the dried material, thereby achieving a uniform drying effect.

[0023] Working principle: First, the staff connects the material conveying pipeline with the feed pipe 4, so that the material passes through the feed pipe 4 and enters the drying cylinder 5. Then, the staff starts the coal-fired furnace 3 to input hot air into the drying cylinder 5. At this time, the staff starts the motor 8, and the motor 8 drives the gear ring 6 to rotate through the gear 9, and the gear ring 6 drives the drying cylinder 5 to rotate between the two mounting plates 2. At the same time, the motor 8 drives the rotating drum 13 to rotate synchronously through the synchronous belt 14, so that the rotating drum 13 drives the corresponding circular box 10 to rotate, and the circular box 10 drives another circular box 10 to rotate synchronously through the positioning cylinder 19. The two circular boxes 10 can drive the four mounting rods 11 to rotate synchronously, so that the mounting rods 11 drive the swiping plate 12 It moves along the inner side of the drying cylinder 5 and scoops up the materials in the drying cylinder 5. The gaps between the multiple scooping plates 12 on the same mounting rod 11 are used to quickly separate the materials accumulated in the drying cylinder 5 to prevent agglomeration. Since the scooping plates 12 on the four mounting rods 11 are staggered, the scooping plates 12 can repeatedly scoop up the materials in the drying cylinder 5 as the four mounting rods 11 rotate. When the materials are discharged, the hot air in the drying cylinder 5 quickly dries the materials. At the same time, the inclined scooping plates 12 can push the materials to the discharge cylinder 26 when rotating. Finally, the dried materials are discharged from the discharge cylinder 26, thereby achieving a uniform drying effect and improving the drying efficiency of the materials.
