Description

Technical Field

[0001] The present invention relates to the technical field of burners, and more particularly, to a rotary boiler. Background Art

[0002] In a rotary boiler, primary air is usually introduced to supply combustion-supporting air to the boiler to ensure that the fuel in the rotary cone can burn normally.

[0003] In the related art, to improve the combustion efficiency of the fuel, the primary air inlet pipe is usually installed on the conical wall of the rotary cone so that the introduced primary air can fully contact the fuel in the rotary cone. However, this also causes the air outlet holes of the inlet pipe to be easily blocked by the fuel, reducing the intake air volume of the primary air and resulting in poor applicability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rotary boiler in view of the defects and deficiencies of the prior art. The rotation of the rotary cone of the rotary boiler drives the anti-blocking block to reciprocate in the exhaust cavity of the exhaust rib, thereby disturbing the ash slag blocking the air outlet holes, realizing periodic cleaning of the air outlet holes, ensuring that the primary air can smoothly enter the combustion cavity from the intake cavity, and improving the applicability of the rotary boiler.

[0005] The rotary boiler according to an embodiment of the present invention includes: a housing and a rotary cone. The rotary cone is rotatably disposed in the housing and defines a combustion cavity, and the central axis of the rotary cone is inclined upward in a direction away from the horizontal plane. The rotary cone has an intake cavity; a air distribution assembly, the air distribution assembly includes a plurality of exhaust ribs arranged circumferentially along the rotary cone. The exhaust ribs have a plurality of exhaust cavities arranged along their length directions. The exhaust cavity has an intake hole and an air outlet hole. The intake cavity is communicated with the exhaust cavity through the intake hole, and the combustion cavity is communicated with the exhaust cavity through the air outlet hole. An anti-blocking block is disposed in the exhaust cavity. The rotation of the rotary cone can drive the anti-blocking block to move in the exhaust cavity, and the movement of the anti-blocking block can open or close the air outlet hole.

[0006] According to the rotary boiler of an embodiment of the present invention, the rotary cone is rotatably arranged in the shell and defines a combustion chamber, and the central axis of the rotary cone is inclined upward in a direction away from the horizontal plane. The rotary cone has an air inlet chamber. The air distribution assembly includes a plurality of exhaust fins arranged circumferentially along the rotary cone. The exhaust fins have a plurality of exhaust chambers arranged along their length directions. The exhaust chambers have air inlet holes and air outlet holes. The air inlet chamber is communicated with the exhaust chambers through the air inlet holes. The combustion chamber is communicated with the exhaust chambers through the air outlet holes. And an anti-blocking block is arranged in the exhaust chamber. The rotation of the rotary cone can drive the anti-blocking block to move in the exhaust chamber. The movement of the anti-blocking block can open or close the air outlet hole. Thus, in the rotary boiler of the present application, after the primary air is introduced into the air inlet chamber, the primary air can enter the exhaust chamber through the air inlet hole, and then enter the combustion chamber through the air outlet hole. The rotation of the rotary cone and the introduced primary air can make the fuel in the combustion chamber in a fluidized combustion state, improving the combustion efficiency of the rotary boiler. And when the rotary cone rotates, the exhaust fins will also rotate accordingly. At this time, the relative height positions on both sides of the exhaust fins will change. Correspondingly, the lowest point of the exhaust chamber will also change continuously. And under the action of gravity, the anti-blocking block is always located at the lowest point of the exhaust chamber. Thus, the rotation of the exhaust fins will drive the anti-blocking block to reciprocate in the exhaust chamber. The reciprocating anti-blocking block can disturb the ash slag blocking the air outlet hole, thereby realizing the periodic cleaning of the air outlet hole, ensuring that the primary air can smoothly enter the combustion chamber from the air inlet chamber, and improving the applicability of the rotary boiler.

The hoop plates surround the outer circumferences of the plurality of air delivery pipes.

[0009] In some embodiments, the rotary boiler further includes an air inlet assembly. The air inlet assembly is communicated with a plurality of the air delivery pipes to supply air to the air delivery pipes.

[0010] In some embodiments, the air inlet assembly includes a gas distribution box. The gas distribution box is rotatably penetrated through the shell through a bearing. The air delivery pipe is communicated with the gas distribution box.

[0011] In some embodiments, the intake assembly further includes a pressing disc and a plurality of air inlet pipes passing through the pressing disc. A plurality of first docking holes are provided on the inner plate of the air distribution box facing the rotary cone, and one end of each of the plurality of gas delivery pipes facing the air distribution box is correspondingly inserted into one of the plurality of first docking holes. A plurality of second docking holes opposite to the first docking holes are provided on the outer plate of the air distribution box facing away from the rotary cone. The pressing disc is pressed against the outer plate of the air distribution box by an elastic member, and the plurality of air inlet pipes are opposite to the plurality of second docking holes.

[0012] In some embodiments, the rotary boiler further includes a secondary combustion cone. The secondary combustion cone is inserted through the housing, and the secondary combustion cone has an exhaust passage communicating with the combustion chamber. A feed inlet communicating with the exhaust passage is provided on a portion of the secondary combustion cone located outside the housing.

[0013] In some embodiments, an air inlet is provided at one end of the secondary combustion cone away from the housing.

Detailed implementation manners

[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0024] As Figures 1-5 shown, the rotary boiler of the embodiment of the present invention includes a shell 1, a rotating cone 2 and an air distribution assembly 3.

[0025] Specifically, the rotating cone 2 is rotatably arranged in the shell 1 and defines a combustion chamber, and the central axis of the rotating cone 2 is inclined upward in a direction away from the horizontal plane. The rotating cone 2 has an air intake chamber. The air distribution assembly 3 includes a plurality of exhaust fins 31 arranged circumferentially along the rotating cone 2. The exhaust fins 31 have a plurality of exhaust cavities 33 arranged along their length directions. The exhaust cavity 33 has an air inlet hole 34 and an air outlet hole 35. The air intake chamber is communicated with the exhaust cavity 33 through the air inlet hole 34. The combustion chamber is communicated with the exhaust cavity 33 through the air outlet hole 35. And an anti-blocking block 32 is arranged in the exhaust cavity 33. The rotation of the rotating cone 2 can drive the anti-blocking block 32 to move in the exhaust cavity 33, and the movement of the anti-blocking block 32 can open or close the air outlet hole 35.

[0026] It can be understood that the air intake chamber can be arranged in the cone wall of the rotating cone 2. After the primary air is introduced into the air intake chamber, the primary air can enter the exhaust cavity 33 through the air inlet hole 34, and then enter the combustion chamber through the air outlet hole 35. Thus, the primary air cooperates with the rotation of the rotating cone 2 to make the fuel in a fluidized combustion state, improving the combustion efficiency of the rotary boiler.

[0027] It can be understood that in the rotary boiler of the present application, the rotating cone 2 is inclined upward and arranged in the shell 1 (such as Figure 1 shown in the up and down direction). When the rotating cone 2 rotates, the exhaust fins 31 will also rotate accordingly. For example, in Figure 3The exhaust fins 31 at the lowest position will rotate to the highest position. At this time, the relative positions on both sides of the exhaust fins 31 will change. The side far from the central axis of the rotary cone 2 will change from the lowest point of the exhaust fins 31 to the highest point, and the side close to the central axis of the rotary cone 2 will change from the highest point of the exhaust fins 31 to the lowest point. Correspondingly, the lowest point of the exhaust cavity 33 will also change continuously. Under the action of gravity, the anti-blocking block 32 is always located at the lowest point of the exhaust cavity 33. Thus, the rotation of the exhaust fins 31 will drive the anti-blocking block 32 to reciprocate in the exhaust cavity 33. The reciprocating anti-blocking block 32 can disturb the ash slag blocked at the air outlet 35, thereby realizing the periodic cleaning of the air outlet 35, ensuring that the primary air can smoothly enter the combustion cavity from the intake cavity, and improving the applicability of the rotary boiler.

[0028] It should be noted that in the rotary boiler of the present application, since the rotary cone 2 is inclined, the fuel in the rotary cone 2 always covers the exhaust fins 31 at the lower position. Therefore, as Figure 3 shown, the air outlet 35 can be arranged on the side of the exhaust fins 31 far from the central axis of the rotary cone 2. When the exhaust fins 31 rotate to the lower position, the anti-blocking block 32 also drops to the side of the exhaust fins 31 far from the central axis of the rotary cone 2. At this time, the anti-blocking block 32 can block the air outlet 35 to prevent the fuel covering the exhaust fins 31 from falling into the exhaust cavity 33 through the air outlet 35, which affects the normal operation of the anti-blocking block 32. When the exhaust fins 31 rotate to the higher position, the anti-blocking block 32 drops to the other side. At this time, the air outlet 35 is opened, and the intake cavity can input the primary air into the combustion cavity from the exhaust cavity 33 without obstruction.

[0029] According to the rotary boiler of the embodiment of the present invention, the rotating cone is rotatably arranged in the shell and defines a combustion chamber, and the central axis of the rotating cone is inclined upward in a direction away from the horizontal plane. The rotating cone has an air inlet chamber. The air distribution assembly includes a plurality of exhaust fins arranged circumferentially along the rotating cone. The exhaust fins have a plurality of exhaust chambers arranged along their length directions. The exhaust chambers have air inlet holes and air outlet holes. The air inlet chamber is communicated with the exhaust chambers through the air inlet holes. The combustion chamber is communicated with the exhaust chambers through the air outlet holes. And an anti-blocking block is arranged in the exhaust chamber. The rotation of the rotating cone can drive the anti-blocking block to move in the exhaust chamber. The movement of the anti-blocking block can open or close the air outlet hole. Thus, in the rotary boiler of the present application, after the primary air is introduced into the air inlet chamber, the primary air can enter the exhaust chamber through the air inlet hole, and then enter the combustion chamber through the air outlet hole. The rotation of the rotating cone and the introduced primary air can make the fuel in the combustion chamber in a fluidized combustion state, improving the combustion efficiency of the rotary boiler. And when the rotating cone rotates, the exhaust fins will also rotate accordingly. At this time, the relative height positions on both sides of the exhaust fins will change. Correspondingly, the lowest point of the exhaust chamber will also change continuously. And under the action of gravity, the anti-blocking block is always located at the lowest point of the exhaust chamber. Thus, the rotation of the exhaust fins will drive the anti-blocking block to reciprocate in the exhaust chamber. The reciprocating anti-blocking block can disturb the ash slag blocking the air outlet hole, thereby realizing the periodic cleaning of the air outlet hole, ensuring that the primary air can smoothly enter the combustion chamber from the air inlet chamber, and improving the applicability of the rotary boiler.

[0030] It can be understood that the gravity of the anti-blocking block 32 itself needs to be greater than the centrifugal force received by the rotation of the anti-blocking block 32, so as to prevent the anti-blocking block 32 from always being located on the side of the exhaust fin 31 away from the central axis of the rotating cone 2 under the action of the centrifugal force, ensuring that the anti-blocking block 32 can reciprocate with the rotation of the rotating cone 2.

[0031] Further, as Figure 1 and Figure 3 shown, the exhaust fin 31 extends in a direction close to the central axis, and the exhaust fin 31 is inclined in the rotation direction of the rotating cone 2.

[0032] It should be noted that as the rotation speed of the rotating cone 2 increases, the fuel in the rotating cone 2 will successively present six motion states: sliding, slumping, rolling, cascading, throwing, and centrifugal. Among them, in the rolling state, the fuel can maintain a fluidized combustion state and the rotation speed of the rotating cone 2 is relatively low at this time, which can not only improve the combustion efficiency but also have a certain economy. And in the rotary boiler of the present application, a plurality of exhaust fins 31 are inclined in the rotating cone 2, and their inclination directions are consistent with the rotation direction of the rotating cone 2. Thus, when the rotating cone 2 rotates, the exhaust fins 31 can also provide a stirring effect on the fuel in the rotating cone 2, so as to realize that at a low rotation speed of the rotating cone 2, the fuel in the rotating cone 2 can quickly enter the rolling state, further improving the economy of the rotary boiler.

[0033] It is understandable that the inclination angle of the exhaust fins 31 should be less than the sliding friction angle of the fuel. Thus, the exhaust fins 31 can quickly make the fuel roll, while also avoiding excessive impact of the rolling fuel on the exhaust fins 31 and enhancing the durability of the exhaust fins 31.

[0034] Furthermore, as Figure 1 and Figure 2 shown, the rotary cone 2 includes a plurality of gas delivery pipes 21 arranged along its circumferential direction. The gas delivery pipes 21 have a plurality of gas delivery holes arranged along their length direction, and the gas delivery holes are communicated with the air inlet holes 34. The rotary cone 2 further includes a plurality of hoop plates (not shown) arranged at intervals along the extension direction of its central axis, and the hoop plates surround the outer periphery of the plurality of gas delivery pipes 21.

[0035] In other words, the gas delivery pipes 21 and the hoop plates cooperate to form the cone wall of the rotary cone 2 in a net frame shape. At this time, the flow channel of the gas delivery pipes 21 can be used as an air inlet chamber for introducing primary air into the combustion chamber, and the hoop plates connect the plurality of gas delivery pipes 21 in sequence in the form of an annular plate, thereby enhancing the structural strength of the rotary cone 2 and ensuring the durability of the rotary cone 2.

[0036] It is understandable that the circumferentially arranged gas delivery pipes 21 optimize the distribution of primary air, enabling the primary air to act uniformly on the fuel combustion and ensuring full combustion of the fuel.

[0037] Preferably, a grille can be arranged within the net frame formed by the gas delivery pipes 21 and the hoop plates, thereby preventing unburned garbage from falling through the net frame, ensuring full combustion of the fuel, and allowing the residues generated from the fuel combustion to fall through the grille.

[0038] Furthermore, as Figure 1 shown, the inclined combustion cone further includes an air inlet assembly 4, and the air inlet assembly 4 is communicated with a plurality of gas delivery pipes 21 to supply air to the gas delivery pipes 21.

[0039] It is understandable that the air inlet assembly 4 can introduce primary air into a plurality of gas delivery pipes 21 simultaneously, thereby ensuring the uniformity of the primary air supply.

[0040] Furthermore, as Figure 1 shown, the air inlet assembly 4 includes a gas distribution box 41. The gas distribution box 41 is rotatably penetrated through the housing 1 by means of a bearing 42, and the gas delivery pipes 21 are communicated with the gas distribution box 41.

[0041] It is understandable that the gas distribution box 41 is connected to the combustion cone through the gas delivery pipes 21. Thus, the gas distribution box 41 rotates synchronously with the rotary cone 2, ensuring a sufficient supply of primary air.

[0042] Furthermore, as Figure 1As shown, the air intake assembly 4 also includes a clamping plate 44 and a plurality of air inlet pipes 43 inserted through the clamping plate 44, a plurality of first docking holes are provided on the inner plate of the air distribution box 41 facing the rotating cone 2, a plurality of air supply pipes 21 are correspondingly inserted into the plurality of first docking holes at one end facing the air distribution box 41, a plurality of second docking holes opposite to the first docking holes are provided on the outer plate of the air distribution box 41 away from the rotating cone 2, the clamping plate 44 is pressed against the outer plate of the air distribution box 41 by an elastic member (not shown), and the plurality of air inlet pipes 43 are opposite to the plurality of second docking holes.

[0043] In other words, on the side of the air distribution box facing the rotating cone 2, the air distribution box and the rotating cone 2 form an integrated structure through the air supply pipe 21 passing through the first docking hole, and the air distribution box rotates together with the rotating cone 2, and on the other side of the air distribution box away from the rotating cone 2, the elastic member presses the clamping plate 44 against the air distribution box, thereby, the air inlet pipe 43 and the air distribution box are rotatably sealed and connected, that is, the flow channel in the air inlet pipe 43 is intermittently connected with the second docking hole, thereby minimizing the loss of primary air and improving the utilization rate of primary air.

[0044] Furthermore, if Figure 1 As shown, the inclined combustion cone also includes a secondary combustion cone 5, which is penetrated through the shell 1 and has an exhaust passage connected to the combustion chamber. The portion of the secondary combustion cone 5 located outside the shell 1 is provided with a feed port 51 connected to the exhaust passage.

[0045] In other words, the fuel can fall from the feed port 51 through the exhaust channel into the rotating cone 2, and the smoke generated by the combustion of the fuel can be discharged through the exhaust channel. In the exhaust channel, the soot mixed in the smoke can continue to undergo secondary combustion and decomposition under high temperature conditions, thereby purifying the exhaust smoke and improving the environmental friendliness of the rotary boiler.

[0046] Furthermore, if Figure 1 As shown, an air inlet 52 communicating with the exhaust passage is provided at one end of the secondary combustion cone 5 away from the shell 1 .

[0047] It is understandable that secondary air can be input into the exhaust channel through the air inlet 52. Under the action of the secondary air, the flue gas generated by the fuel combustion forms a vortex gas, which increases the residence time of the flue gas in the secondary combustion cone 5, thereby ensuring that the ash in the flue gas can be fully decomposed by high temperature.

[0048] Furthermore, if Figure 1 As shown, the cross-sectional area of ​​the exhaust passage gradually decreases in a direction away from the housing 1 .

[0049] It can be understood that the tapered exhaust passage can create a throttling and speed-increasing effect on the combustion flue gas, thereby improving the mixing effect of the secondary air and the flue gas.

[0050] Furthermore, if Figure 1As shown, the inclined combustion cone further includes a slag discharging assembly 53. The slag discharging assembly 53 includes a screw conveyor shaft 61 and a driving member (not shown). The housing 1 has a slag discharging chamber for installing the screw conveyor shaft 61. The slag discharging chamber communicates with the combustion chamber, and the slag discharging chamber has a slag outlet 62. The driving member can drive the screw conveyor shaft 61 to rotate, and the rotation of the screw conveyor shaft 61 can convey the ash discharged from the combustion chamber to the slag outlet 62 for discharging.

[0051] It can be understood that the slag discharging chamber can be arranged below the rotary cone 2. Thus, during the process of incinerating garbage, the ash generated by the combustion of the garbage in the combustion chamber will fall from the rotary cone 2 into the slag discharging chamber for discharging, avoiding excessive accumulation of ash in the housing 1 and improving the combustion efficiency of the rotary boiler.
