Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a burner for low-quality coal. Background Technology

[0002] In the energy sector, low-quality coal is widely used in industrial boilers, power plant boilers, and other equipment due to its abundant reserves and relatively low cost. However, low-quality coal typically has characteristics such as low volatile matter, high ash content, and low calorific value, which makes it difficult to burn, easily leading to incomplete combustion, low thermal efficiency, and high pollutant emissions. Therefore, burner design is crucial to improving the combustion efficiency of low-quality coal and reducing pollutant emissions.

[0003] Existing low-quality coal burners have some shortcomings in use. On the one hand, different furnace bodies have different heights, while the height of existing burners is mostly fixed, making it difficult to adjust flexibly according to the actual height of the furnace body. This results in poor compatibility between the burner and the furnace body, affecting the combustion effect. On the other hand, during combustion, due to the complex combustion characteristics of low-quality coal, the horizontal position of the burner needs to be adjusted according to the combustion conditions to achieve uniform fuel distribution and efficient combustion. However, existing burners often cannot adjust the horizontal position in real time, making it difficult to adapt to the dynamic changes in the combustion process of low-quality coal, resulting in incomplete combustion and serious energy waste. Utility Model Content

[0004] This invention addresses the above problems by providing a simple and easily adjustable burner for low-quality coal.

[0005] The technical solution of this utility model is as follows: a low-quality coal burner, comprising a burner body and a mounting plate, wherein two movable seats are slidably connected to the upper surface of the mounting plate, and a support rod is slidably connected inside each of the two movable seats, and a support base is installed at the other end of the support rod. The burner body is installed inside the two support seats, and a first threaded plate is installed between the two movable seats. A connecting plate is installed on the bottom surface of each of the two support seats, and a T-shaped plate is slidably connected inside each of the two connecting plates. A second threaded plate is installed between the two T-shaped plates, and a driving mechanism is provided in the middle of the upper surface of the mounting plate.

[0006] Preferably, the drive mechanism includes a U-shaped plate mounted on the upper surface of the mounting plate, a first support plate is installed inside the U-shaped plate, and a drive shaft, a first driven shaft and a second driven shaft are rotatably mounted between the first support plate and one side wall of the U-shaped plate.

[0007] Preferably, a first one-way bearing is mounted on the outer surface of the drive shaft, and a first synchronous pulley is mounted on the outer surface of both the first one-way bearing and the first driven shaft. The two first synchronous pulleys are connected by a first synchronous belt drive.

[0008] Preferably, a first reciprocating screw is rotatably mounted between the first support plate and the other side wall of the U-shaped plate, and the first reciprocating screw is connected to one end of the first driven shaft, and the first threaded plate is threadedly connected to the first reciprocating screw.

[0009] Preferably, a second one-way bearing is mounted on the outer surface of the drive shaft, and a second synchronous pulley is mounted on the outer surface of both the second driven shaft and the second one-way bearing. The two second synchronous pulleys are connected by a second synchronous belt drive.

[0010] Preferably, a third driven shaft is rotatably mounted inside the U-shaped plate, and the third driven shaft and the second driven shaft are connected by a bevel gear set. A second support plate is mounted on the outer surface of the first support plate. A second reciprocating screw is rotatably mounted between the second support plate and the inner top wall of the U-shaped plate. A third synchronous pulley is fixedly connected to the outer surface of both the second reciprocating screw and the third driven shaft. The two third synchronous pulleys are connected by a third synchronous belt. The second threaded plate is threadedly connected to the outer surface of the second reciprocating screw.

[0011] Preferably, a motor is mounted on the outer surface of the U-shaped plate, and the output end of the motor is connected to one end of the drive shaft.

[0012] In operation, this invention employs a drive mechanism that, when the motor rotates forward, drives the second reciprocating screw to rotate, causing the second threaded plate to move up and down. This, in turn, allows for height adjustment of the burner body via a connecting plate and support rod. When the motor rotates in reverse, it drives the first driven shaft and the first reciprocating screw to rotate, causing the first threaded plate to move horizontally. This, along with the moving seat and support rod, allows for horizontal position adjustment of the burner body. This effectively solves the problems of poor adaptability and inability to adjust the horizontal position of the burner according to the combustion conditions of low-quality coal in existing burners, thereby significantly improving the combustion effect of low-quality coal.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-5 As shown, a low-quality coal burner includes a burner body 1 and a mounting plate 2. Two movable seats 3 are slidably connected to the upper surface of the mounting plate 2. Support rods 4 are slidably connected inside the two movable seats 3, and support seats 5 are installed at the other end of the support rods 4. The burner body 1 is installed inside the two support seats 5. A first threaded plate 14 is installed between the two movable seats 3. A connecting plate 22 is installed on the bottom surface of the two support seats 5. T-shaped plates are slidably connected inside the two connecting plates 22. A second threaded plate 21 is installed between the two T-shaped plates. The sliding connection between the support rods 4 and the movable seats 3 ensures that the support seats 5 can move synchronously with the movable seats 3 when they move horizontally, and can slide up and down along the movable seats 3 when the height is adjusted. The sliding cooperation between the T-shaped plates and the connecting plates 22 allows the connecting plates 22 to move along the T-shaped plates when the second threaded plate 21 moves the T-shaped plates up and down. When the burner body 1 moves horizontally, the connecting plates 22 and the T-shaped plates can slide relative to each other, avoiding structural interference.

[0021] A drive mechanism is provided in the middle of the upper surface of the mounting plate 2. The drive mechanism includes a U-shaped plate 6 mounted on the upper surface of the mounting plate 2. A first support plate 7 is installed inside the U-shaped plate 6. A drive shaft 8, a first driven shaft 9, and a second driven shaft 10 are rotatably mounted between the first support plate 7 and one side wall of the U-shaped plate 6. A motor 23 is mounted on the outer surface of the U-shaped plate 6. The output end of the motor 23 is connected to one end of the drive shaft 8. The motor 23 is a power source and transmits power through the drive shaft 8.

[0022] A first one-way bearing 11 is mounted on the outer surface of the drive shaft 8. A first synchronous pulley 12 is mounted on the outer surface of both the first one-way bearing 11 and the first driven shaft 9. The two first synchronous pulleys 12 are connected by a first synchronous belt. The first one-way bearing 11 transmits torque only when the drive shaft 8 rotates in reverse. At this time, the first synchronous pulley 12 drives the first driven shaft 9 to rotate through the first synchronous belt. When the drive shaft 8 rotates forward, the first one-way bearing 11 rotates freely and the first driven shaft 9 does not participate in the transmission.

[0023] A first reciprocating screw 13 is rotatably installed between the first support plate 7 and the other side wall of the U-shaped plate 6, and the first reciprocating screw 13 is connected to one end of the first driven shaft 9. The first threaded plate 14 is threadedly connected to the first reciprocating screw 13. When the first driven shaft 9 rotates, it drives the first reciprocating screw 13 to rotate. The first threaded plate 14 is threadedly engaged with the first reciprocating screw 13, converting the rotational motion into linear motion, thereby driving the first threaded plate 14 to move horizontally, and thus driving the moving seat 3 and the burner body 1 to adjust their horizontal positions.

[0024] A second one-way bearing 15 is mounted on the outer surface of the drive shaft 8. A second synchronous pulley 16 is mounted on the outer surface of both the second driven shaft 10 and the second one-way bearing 15. The two second synchronous pulleys 16 are connected by a second synchronous belt. The second one-way bearing 15 transmits torque only when the drive shaft 8 rotates forward. At this time, the second synchronous pulley 16 drives the second driven shaft 10 to rotate through the second synchronous belt. When the drive shaft 8 rotates in reverse, the second one-way bearing 15 rotates freely, and the second driven shaft 10 does not participate in the transmission.

[0025] A third driven shaft 17 is rotatably mounted inside the U-shaped plate 6. The third driven shaft 17 and the second driven shaft 10 are connected by a bevel gear set. A second support plate 18 is mounted on the outer surface of the first support plate 7. A second reciprocating screw 19 is rotatably mounted between the second support plate 18 and the inner top wall of the U-shaped plate 6. A third synchronous pulley 20 is fixedly connected to the outer surface of both the second reciprocating screw 19 and the third driven shaft 17. The two third synchronous pulleys 20 are connected by a third synchronous belt. A second threaded plate 21 is threadedly connected to the outer surface of the second reciprocating screw 19. The bevel gear set consists of two bevel gears. One bevel gear is mounted on the outer surface of the second driven shaft 10, and the other bevel gear is mounted on the outer surface of the third driven shaft 17. The two bevel gears mesh with each other. When the second driven shaft 10 rotates, it drives the third driven shaft 17 to rotate through the bevel gear set. The third synchronous pulley 20 and the third synchronous belt transmit power to the second reciprocating screw 19. The second threaded plate 21 is threaded with the second reciprocating screw 19, causing it to move up and down. In turn, the T-shaped plate and the connecting plate 22 drive the support base 5 and the burner body 1 to adjust their height up and down.

[0026] In a specific application, when the motor 23 rotates forward, the drive shaft 8 drives the second one-way bearing 15 to rotate. The second one-way bearing 15 drives the second driven shaft 10 to rotate through the second synchronous pulley 16 and the second synchronous belt. The second driven shaft 10 drives the third driven shaft 17 to rotate through the bevel gear set. The third driven shaft 17 drives the second reciprocating screw 19 to rotate through the third synchronous pulley 20 and the third synchronous belt. The second threaded plate 21 moves up and down along the second reciprocating screw 19, and drives the connecting plate 22, the support seat 5 and the burner body 1 to move up and down through the T-shaped plate to achieve height adjustment. At this time, the first one-way bearing 11 rotates idling, and the first driven shaft 9 and the first reciprocating screw 13 do not participate in the transmission.

[0027] When the motor 23 reverses, the drive shaft 8 drives the first one-way bearing 11 to rotate. The first one-way bearing 11 drives the first driven shaft 9 to rotate through the first synchronous pulley 12 and the first synchronous belt. The first driven shaft 9 drives the first reciprocating screw 13 to rotate. The first threaded plate 14 moves horizontally along the first reciprocating screw 13, causing the moving seat 3 to slide on the mounting plate 2. The moving seat 3 drives the support seat 5 and the burner body 1 to move horizontally through the support rod 4, realizing horizontal position adjustment. At this time, the second one-way bearing 15 rotates idling, and the second driven shaft 10 and the second reciprocating screw 19 do not participate in the transmission.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
