DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] like Figure 1-4As shown, the slag discharge device of the inclined rotating cone burner of the embodiment of the utility model, the burner 1 has a chamber 11 and a slag discharge port 12, the slag discharge port 12 is arranged on the wall surface of the burner 1 and is connected with the chamber 11. The slag discharge device 2 includes a stopper 21, a rotating shaft 22 and a stopper 23. The stopper 21 is arranged on the inner wall surface of the chamber 11 and rotates between a first position 31 and a second position 32 relative to the inner wall surface of the chamber 11. When the stopper 21 is located at the first position 31, the stopper 21 is used to close the slag discharge port 12, and when the stopper 21 is located at the second position 32, the stopper 21 is away from the slag discharge port 12. The rotating shaft 22 is arranged on the burner 1 and can rotate relative to the burner 1, and at least part of the stopper 21 is connected to the rotating shaft 22. The stopper 23 is arranged on the inner wall surface of the chamber 11, and the rotating shaft 22 is located between the slag discharge port 12 and the stopper 23, and the stopper 23 is used to limit the stopper 21. Specifically, one end of the limiting member 23 is fixedly connected to the inner wall surface of the chamber 11 , and the other end of the limiting member 23 extends along the diameter of the chamber 11 toward the center of the chamber 11 .

[0024] The slag discharge device of the inclined rotating cone burner of the utility model embodiment, when the baffle 21 is in the first position 31, the baffle 21 closes the slag discharge port 12, so that the material in the chamber 11 is not easy to leak through the slag discharge port 12, and when the baffle 21 is in the second position 32, the baffle 21 is away from the slag discharge port 12, and the slag discharge port 12 is in an open state, so that the ash and slag in the chamber 11 are easy to be discharged from the slag discharge port 12, and the baffle 21 is rotated between the first position 31 and the second position 32, so that the burner 1 can be switched between the "normal operation" and "slag discharge" states, thereby realizing the online slag discharge function of the burner 1, effectively solving the problem of poor slag discharge of the burner 1, and improving the combustion efficiency of the material in the burner 1, and the limit member 23 plays a role of limiting the baffle 21 when it rotates toward the second position 32, thereby limiting the movable range of the baffle 211, so that the baffle 211 can be easily rotated from the second position 32 to the first position 31.

[0025] Specifically, Figure 3 As shown, when the inclined rotating cone burner 1 is in the slag discharge operation state, the inclined rotating cone burner 1 rotates clockwise, and the surface running direction of the material layer composed of fuel and ash in the chamber 11 is as shown by the arrow. When the slag discharge port 12 on the burner 1 rotates to the bottom, the blocking member 21 rotates from the first position 31 to the second position 32. Due to the limitation of the limit member 23, the impact force of the moving particles cannot push the blocking member 21, and the slag discharge port 12 is in an open state, which is convenient for the ash in the chamber 11 to be discharged.

[0026] like Figure 4As shown, when the inclined rotating cone burner 1 is in normal operation, the inclined rotating cone burner 1 rotates counterclockwise, and the surface running direction of the material layer composed of fuel and ash in the chamber 11 is as shown by the arrow. When the slag discharge port 12 on the burner 1 rotates to the bottom, the blocking member 21 rotates from the second position 32 to the first position 31, and the impact force of the moving particles pushes down the blocking member 21 and covers the slag discharge port 12. The slag discharge port 12 is in a closed state, so that the material in the chamber 11 is not easily discharged from the chamber 11.

[0027] Specifically, the size of the slag discharge port 12 is 1.2 times of the largest fuel slag block in the chamber 11 , so that the fuel slag block can be discharged from the slag discharge port 12 .

[0028] In some embodiments, the baffle 21 includes a baffle 211, a connecting rod 212 and a weight 213, the connecting rod 212 is connected to the rotating shaft 22, one end of the connecting rod 212 is located in the chamber 11 and connected to the baffle 211, and the other end of the connecting rod 212 is located outside the chamber 11 and connected to the weight 213.

[0029] Specifically, by setting a weight 213, when the block 21 on the burner 1 rotates downward, under the action of its own gravity, the weight 213 drives the baffle 211 to move to the second position 32. When the block 21 on the burner 1 rotates to the bottom, the baffle 211 is located at the second position 32, and the slag discharge port 12 is opened. When the block 21 on the burner 1 rotates upward, the weight 213 moves toward the outer wall surface of the burner 1 under the action of its own gravity, so that the baffle 211 moves toward the first position 31. When the block 21 on the burner 1 rotates to the top, the baffle 211 is located at the first position 31, and the baffle 211 closes the slag discharge port 12. Thus, by rotating the burner 1, the baffle 211 can automatically rotate between the first position 31 and the second position 32, realizing the online slag discharge function of the burner 1, and the operation method is simple. Moreover, the structure of the block 21 is simple, easy to manufacture, and cost-saving.

[0030] Specifically, the connecting rod 212 is a heat-resistant metal rod.

[0031] In some embodiments, one end of the connecting rod 212 is connected to the side of the baffle 211 adjacent to the limiting member 23 , so that the baffle 211 can be more easily rotated between the first position 31 and the second position 32 under the driving action of the weight 213 .

[0032] In some embodiments, the connection between the connecting rod 212 and the rotating shaft 22 is located at the middle position in the length direction of the connecting rod 212. Specifically, the rotating shaft 22 is located at the middle position in the length direction of the connecting rod 212, and the length of the connecting rod 212 located in the chamber 11 is equal to the length of the connecting rod 212 located outside the chamber 11, so that the mass distribution of the connecting rod 212 on both sides of the rotating shaft 22 is uniform, and the stopper 21 and the weight 213 respectively arranged at both ends of the connecting rod 212 are more likely to swing with the rotating shaft 22 as the fulcrum, ensuring that the burner 1 switches between the two states of "normal operation" and "slag discharge" more smoothly.

[0033] In some embodiments, the connecting rod 212 and the weight 213 are integrally formed, thereby improving the stability and integrity of the connecting rod 212 and the weight 213 structures.

[0034] In some embodiments, the baffle 211 includes a first part 2111 and a second part 2112, the second part 2112 is arranged on the side of the first part 2111 adjacent to the limit member 23, the cross-sectional area of ​​the second part 2112 gradually decreases from one end of the second part 2112 adjacent to the first part 2111 to the end of the second part 2112 away from the first part 2111, and one end of the connecting rod 212 is connected to the side of the second part 2112 adjacent to the limit member 23.

[0035] Specifically, since the cross-sectional area of ​​the end of the second part 2112 away from the first part 2111 is smaller than the cross-sectional area of ​​the first part 2111, when the baffle 211 rotates to the second position 32, the second part 2112 is not easy to fit with the limit member 23, making it easier for the baffle 211 to rotate from the second position 32 to the first position 31 under the action of the weight 213.

[0036] In some embodiments, the cross-sectional area of ​​the baffle 211 is larger than the cross-sectional area of ​​the slag discharge port 12, so that when the baffle 211 blocks and closes the slag discharge port 12, the efficiency is higher.

[0037] In some embodiments, an angle 4 is formed between the side of the baffle 211 adjacent to the slag discharge port 12 and the slag discharge port 12, and the angle 4 is greater than or equal to 0° and less than or equal to 90°. Specifically, when the baffle 211 is located at the first position 31, the angle 4 between the side of the baffle 211 adjacent to the slag discharge port 12 and the slag discharge port 12 is 0°, and when the baffle 211 is located at the second position 32, the angle 4 between the side of the baffle 211 adjacent to the slag discharge port 12 and the slag discharge port 12 is less than or equal to 90°.

[0038] In some embodiments, there are at least two stoppers 21, and at least two stoppers 21 are evenly arranged at circumferential intervals around the burner 1, there are at least two rotating shafts 22, and at least two rotating shafts 22 are evenly arranged at circumferential intervals around the burner 1, and at least two rotating shafts 22 correspond one-to-one with at least two stoppers 21, and there are at least two stoppers 23, and at least two stoppers 23 are evenly arranged at circumferential intervals around the burner 1, and at least two stoppers 23 correspond one-to-one with at least two stoppers 21. Specifically, through the above-mentioned settings, the slag discharge efficiency of the slag discharge device 2 can be effectively improved, and the combustion efficiency of the burner 1 can be improved.
