Description

Technical Field

[0001] The invention relates to the technical field of rotary kiln burners, in particular to a rotary kiln denitration multi-stage burner with an anti-vibration shock function. Background Art

[0002] A rotary kiln burner is a device used to inject gas or oil fuel into the furnace of a rotary kiln to calcine materials. It is also called a rotary kiln burner or a rotary kiln burner. The main function of a rotary kiln burner is to provide enough heat to allow the materials in the rotary kiln to reach the required heat treatment temperature. In addition, the base of the rotary kiln burner usually connects the central pipe to the burner body through a rotary connection, which is mainly used to transport combustion-supporting gas or denitrification medium into the kiln.

[0003] The existing rotary kiln denitrification multi-stage burner does not have the anti-vibration function when transporting fuel through the central pipe, which can easily cause obvious axial movement and radial runout of the pipeline. This will not only increase the vibration and stress concentration during equipment operation, but may also have a negative impact on combustion efficiency, burner positioning accuracy and pipeline service life, and even cause more serious equipment safety hazards. Summary of the invention

[0004] The object of the present invention is to provide a rotary kiln denitrification multi-stage burner with an anti-vibration function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: the rotary kiln denitrification multi-stage burner with anti-vibration impact function comprises a rotary kiln and a burner, a central pipe is arranged in the burner, and a fixed seat is installed on the burner, a fixed frame is installed on the fixed seat, two groups of vertical rods are symmetrically installed on the fixed frame, and slide plates are slidably installed on the two groups of vertical rods, and the upper and lower ends of the slide plates are respectively connected to the fixed frame through buffer springs, and a sliding bearing is installed on the slide plate, and a butt pipe is installed in the sliding bearing, and a connecting flange is installed at one end of the butt pipe, and the connecting flange is connected to the central pipe, and a fixing rod is installed at the bottom of the fixing seat, and a feeding port is installed on the fixing rod, and a distributor is rotatably installed on the feeding port, and the distributor is fixedly connected to the other end of the butt pipe, and a gas distributor is arranged on the distributor. The body tube and the liquid tube, the gas tube is connected with the butt tube, the liquid tube passes through the butt tube and extends into the central tube. When the mixed fuel enters the feed port, the gas combustion and liquid fuel can be respectively transported to the burner through the central tube through the gas tube and the liquid tube on the distributor to form multi-stage combustion. At the same time, when the central tube undergoes radial runout or axial movement, since the slide plate can slide on the vertical rod and the slide plate can compress the buffer spring during movement, the elastic deformation of the buffer spring can be used to absorb and eliminate the radial runout generated by the central tube during operation, thereby ensuring that the equipment maintains stability under vibration or impact force. The sliding bearings set at the connection of the central tube can also be used to enable the tube to freely adapt to axial movement, thereby effectively avoiding stress concentration or structural damage caused by limited axial displacement.

[0006] As a preferred technical solution, the burner is provided with a rotary primary utilization component, a rotary secondary utilization component and a support component, and the rotation of the central pipe is used to provide operating driving force for the rotary primary utilization component, the rotary secondary utilization component and the support component.

[0007] As a preferred technical solution, the rotary primary utilization assembly includes a driving wheel, a fixed plate, a rotating shaft, a transmission wheel, a reciprocating screw, a transmission bevel gear, a driven bevel gear, a first transmission belt, a fixed ring, a rotating ring, a linkage rod, a driven ring wheel, a gas detector and a second transmission belt;

[0008] A driving wheel is installed on the material distributor. Two fixing plates are symmetrically installed on the fixed seat. Rotating shafts are installed on both of the two fixing plates in a rotating manner. Driving wheels are installed at the relative ends of the two rotating shafts. A reciprocating lead screw is installed at the center of the end of the driving wheel away from the rotating shaft. A transmission bevel gear is installed at the other end of the reciprocating lead screw. A driven bevel gear is installed on the fixed seat. Both of the two transmission bevel gears are engaged with the driven bevel gear. A first transmission belt is sleeved on the driving wheel and one of the driving wheels. A fixing ring is fixedly installed on one side of the burner close to the connecting flange. A rotating ring is rotatably installed in the fixing ring. A linkage rod is installed on the rotating ring. A driven ring gear is installed on the linkage rod. A second transmission belt is sleeved on the driven ring gear and the other driving wheel. A gas detector is arranged on the driven ring gear. When the central pipeline rotates, the central pipeline can drive the driving wheel on the material distributor to rotate synchronously through the docking pipe, so that the driving wheel can drive one of the driving wheels to rotate in the same direction through the first transmission belt. At this time, the driving wheel can drive one of the transmission bevel gears to rotate synchronously through the reciprocating lead screw. Through the meshing action of the two transmission bevel gears and the driven bevel gear, the reverse rotation of the other driving wheel can be realized, so that the other driving wheel can drive the driven ring gear to rotate through the second transmission belt, which is beneficial to driving the gas detector to rotate synchronously during the rotation of the driven ring gear, realizing that the rotation direction of the gas detector is opposite to the rotation direction of the central pipeline, and further improving the detection efficiency of the gas detector.

[0009] As a preferred technical solution, the rotary multi-stage utilization component includes a sliding seat, a transmission rod, a pressing plate, a bottom plate, a driving airbag, a sliding hole, a sliding rod, a stress ring, a connecting ring, a driven airbag, a transmission ring and a connecting rod;

[0010] Sliding seats are installed on both of the reciprocating lead screws. A transmission rod is installed on the sliding seat, and an extrusion plate is installed on the transmission rod. Two groups of bottom plates are symmetrically installed on the fixed seat. The two sides of the extrusion plate are respectively connected to two bottom plates in one group through driving air bags. A sliding hole is formed in the driven ring gear, and a sliding rod is slidably installed in the sliding hole. A stress ring is installed at the end of the sliding rod close to the fixed ring. A connecting ring is rotatably installed on the stress ring. The connecting ring and the fixed ring are connected through a driven air bag. The input end of the driven air bag and the output end of the driving air bag are connected through a one-way air pipe. The other end of the sliding rod is installed with a transmission ring. A connecting rod is installed on the transmission ring, and a gas detector is installed on the connecting rod. When the reciprocating lead screw rotates, the sliding seat on the reciprocating lead screw can be horizontally reciprocated. By using the horizontal reciprocating movement of the sliding seat, the corresponding two driving air bags can be alternately driven to operate, so that the driving air bag continuously supplies air to the driven air bag through the one-way air pipe. Through the volume expansion of the driven air bag under the action of the air flow, the driven air bag can push the stress ring to move horizontally, so that the stress ring can drive the transmission ring to move synchronously through the sliding rod, which is beneficial for the transmission ring to drive the gas detector to move to the joint of the central pipe and the connecting flange through the connecting rod.

[0011] As a preferred technical solution, a one-way air suction pipe is installed on the input end of the driving air bag, and a pressure stabilizing valve and an exhaust valve are installed on the output end of the driven air bag. Through the setting of the pressure stabilizing valve, the driven air bag can be continuously kept in an expanded state, and the driven air bag can be prevented from bursting. The connecting ring and the fixed ring are connected through an elastic tie belt. Through the setting of the exhaust valve, after the exhaust valve is opened, the stress ring can be driven to move back and reset under the pulling force of the elastic tie belt.

[0012] As a preferred technical solution, the support assembly includes a connecting plate, a rotating column, an electric ejector rod, a pressing plate, a curved track, an annular track, a fixed block, a sliding track, a sliding block, a driving shaft, a linkage rod and a support block;

[0013] A connecting plate is installed on the fixed plate near the feeding port. A rotating column is rotatably installed on the connecting plate. An electric ejector rod is installed at the end of the rotating column close to the fixed plate. A tightening plate is installed on the electric ejector rod. A curved track and an annular track are provided on the rotating column. The curved track is connected to the annular track. A fixed block is installed on the fixed seat. A slide track is opened on the fixed block. A slider is slidably installed in the slide track. A driving shaft is installed at the upper end of the slider. The driving shaft slidably penetrates in the curved track. A connecting rod is installed at the lower end of the slider. A supporting block is installed on the connecting rod. When the burner operates, the electric ejector rod can control the tightening plate to be close to the rotating shaft, so that the rotating shaft can drive the rotating column to rotate synchronously through the electric ejector rod. When the rotating column rotates, due to the extrusion force of the curved track on the driving shaft, the driving shaft can be moved along the curved track into the annular track, so that the driving shaft can drive the slider to move in the slide track, so that the slider can drive the supporting block to be close to the feeding port through the connecting rod, forming continuous support of the supporting block for the feeding port, and the feeding port can be prevented from being damaged under axial displacement.

[0014] As a preferred technical solution, the electric ejector rod is electrically connected to the burner, and the central pipeline rotates counterclockwise.

[0015] As a preferred technical solution, the inner ring wall of the annular track close to the curved track is threaded. The fixed rod and the connecting rod are connected by a supporting elastic sheet. When the burner stops operating, the electric ejector rod can control the tightening plate to disengage from the rotating shaft, so that under the elastic force of the supporting elastic sheet, the driving supporting block can disengage from the feeding port, which is beneficial to enabling the driving shaft to move back from the annular track into the curved track, and is beneficial to the subsequent use of the supporting block.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] When the central pipeline has radial runout or axial displacement, since the sliding plate can slide on the vertical rod, the buffer spring can be compressed during the movement of the sliding plate, and the elastic deformation of the buffer spring can be used to absorb and eliminate the radial runout generated during the operation of the central pipeline, ensuring the stability of the equipment under the action of vibration or impact force. The sliding bearing provided at the connection of the central pipeline can also be used to enable the pipeline to freely adapt to axial displacement, thus effectively avoiding stress concentration or structural damage caused by limited axial displacement.

[0018] In this application, through the provided rotary primary utilization component, the central pipeline can drive the driving wheel to rotate synchronously, enabling the driving wheel to drive a transmission wheel to rotate in the same direction. Then, through the meshing action of two transmission bevel gears and a driven bevel gear, the reverse rotation of another transmission wheel can be achieved. As a result, the other transmission wheel can drive the driven ring wheel to rotate through the second transmission belt, which is beneficial for the driven ring wheel to drive the gas detector to rotate synchronously during rotation, realizing that the rotation direction of the gas detector is opposite to that of the central pipeline, and further improving the detection efficiency of the gas detector.

[0019] In this application, through the provided rotary secondary utilization component, the transverse reciprocating movement of the sliding seat can alternately drive two corresponding driving air bags to operate, forming continuous air supply from the driving air bags to the driven air bags through the one-way air pipes, enabling the driven air bags to push the force-bearing ring to move horizontally, which is beneficial for the transmission ring to drive the gas detector to move to the joint of the central pipeline and the connecting flange.

[0020] In this application, through the provided support component, the rotating shaft can drive the rotating column to rotate synchronously through the electric ejector rod, enabling the drive shaft to move along the curved path into the annular path. Thus, the drive shaft can drive the slider to move within the slideway, and the slider can drive the support block to closely adhere to the feeding port through the linkage rod, forming continuous support of the support block for the feeding port, which can prevent the feeding port from being damaged under axial movement.

A second transmission belt 1714 is sleeved on the driven ring gear 1712 and the other transmission wheel 1704. A gas detector 1713 is arranged on the driven ring gear 1712. When the central pipeline 3 rotates, the central pipeline 3 can drive the driving wheel 1701 on the material distributor 13 to rotate synchronously through the docking pipe 10, so that the driving wheel 1701 can drive one of the transmission wheels 1704 to rotate in the same direction through the first transmission belt 1708. At this time, the transmission wheel 1704 can drive one of the transmission bevel gears 1706 to rotate synchronously through the reciprocating lead screw 1705.

[0038] As Figures 1 - 8 shown, the rotary multi-stage utilization component 18 includes a sliding seat 1801, a transmission rod 1802, a pressing plate 1803, a bottom plate 1804, a driving air bag 1805, a sliding hole 1806, a sliding rod 1807, a stress ring 1808, a connecting ring 1809, a driven air bag 1810, a transmission ring 1811 and a connecting rod 1812;

[0039] A sliding seat 1801 is slidably mounted on each of the two reciprocating lead screws 1705. A transmission rod 1802 is mounted on the sliding seat 1801, and an extrusion plate 1803 is mounted on the transmission rod 1802. Two groups of bottom plates 1804 are symmetrically mounted on the fixed seat 4. The two sides of the extrusion plate 1803 are respectively connected to two bottom plates 1804 in a group through a driving airbag 1805. A sliding hole 1806 is formed in the driven ring gear 1712.

A connecting ring 1809 is rotatably mounted on the stress ring 1808. The connecting ring 1809 is connected to the fixed ring 1709 through a driven airbag 1810. The input end of the driven airbag 1810 is connected to the output end of the driving airbag 1805 through a one-way air pipe. The other end of the sliding rod 1807 is mounted with a transmission ring 1811. A connecting rod 1812 is mounted on the transmission ring 1811. A gas detector 1713 is mounted on the connecting rod 1812. When the reciprocating lead screw 1705 rotates, the sliding seat 1801 on the reciprocating lead screw 1705 can be horizontally reciprocated. By using the horizontal reciprocating movement of the sliding seat 1801, the corresponding two driving airbags 1805 can be alternately driven to operate, forming continuous air supply from the driving airbag 1805 to the driven airbag 1810 through the one-way air pipe. Through the volume expansion of the driven airbag 1810 under the action of the air flow force, the driven airbag 1810 can push the stress ring 1808 to move horizontally, so that the stress ring 1808 can drive the transmission ring 1811 to move synchronously through the sliding rod 1807, which is beneficial for the transmission ring 1811 to drive the gas detector 1713 to move to the joint of the central pipe 3 and the connecting flange 16 through the connecting rod 1812.

Through the setting of the exhaust valve, after the exhaust valve is opened, the stress ring 1808 can be driven to move back to the original position under the pulling force of the elastic lace.

[0041] As Figures 1 - 4 and Figures 7 - 8 shown, the support assembly 19 includes a connecting plate 1901, a rotating column 1902, an electric ejector rod 1903, a pressing plate 1904, a curved track 1905, an annular track 1906, a fixed block 1907, a slide track 1908, a slider 1909, a driving shaft 1910, a linkage rod 1911 and a support block 1912;

[0042] A connecting plate 1901 is installed on the fixed plate 1702 near the feeding port 12. A rotating column 1902 is rotatably installed on the connecting plate 1901. An electric ejector rod 1903 is installed at the end of the rotating column 1902 close to the fixed plate 1702. A pressing plate 1904 is installed on the electric ejector rod 1903. A curved track 1905 and an annular track 1906 are arranged on the rotating column 1902. The curved track 1905 is connected to the annular track 1906. A fixed block 1907 is installed on the fixed seat 4. A slide track 1908 is formed on the fixed block 1907. A slide block 1909 is slidably installed in the slide track 1908. A driving shaft 1910 is installed at the upper end of the slide block 1909. The driving shaft 1910 is slidably inserted into the curved track 1905.

When the burner 2 operates, the electric ejector rod 1903 can control the pressing plate 1904 to press against the rotating shaft 1703, so that the rotating shaft 1703 can drive the rotating column 1902 to rotate synchronously through the electric ejector rod 1903. When the rotating column 1902 rotates, due to the extrusion force of the curved track 1905 on the driving shaft 1910, the driving shaft 1910 can be made to move along the curved track 1905 into the annular track 1906, so that the driving shaft 1910 can drive the slide block 1909 to move in the slide track 1908, and then the slide block 1909 can drive the supporting block 1912 to closely adhere to the feeding port 12 through the linkage rod 1911, forming continuous support of the supporting block 1912 for the feeding port 12, and preventing the feeding port 12 from being damaged under axial movement.

[0043] The electric ejector rod 1903 is electrically connected to the burner 2, and the central pipeline 3 rotates counterclockwise.

[0044] The inner circumferential wall of one side of the annular track 1906 close to the curved track 1905 is threaded. The fixed rod 11 and the linkage rod 1911 are connected by a supporting elastic sheet 1913. When the burner 2 stops operating, the electric ejector rod 1903 can control the pressing plate 1904 to disengage from the rotating shaft 1703, so that under the elastic force of the supporting elastic sheet 1913, the driving supporting block 1912 can disengage from the feeding port 12, which is beneficial to enabling the driving shaft 1910 to move back from the annular track 1906 into the curved track 1905, and is beneficial to the subsequent use of the supporting block 1912.

[0045] The working principle of the present invention:

[0046] When the mixed fuel enters the feed port 12, the gas combustion and liquid fuel can be respectively transported to the burner 2 through the central pipe 3 through the gas pipe 14 and the liquid pipe 15 on the distributor 13 to form multi-stage combustion. At the same time, when the central pipe 3 undergoes radial runout or axial movement, since the slide plate 7 can slide on the vertical rod 6, the slide plate 7 can compress the buffer spring 8 during movement. The elastic deformation of the buffer spring 8 can be used to absorb and eliminate the radial runout generated by the central pipe 3 during operation, ensuring that the equipment maintains stability under vibration or impact force. The sliding bearing 9 set at the connection of the central pipe 3 can also be used to allow the pipe to freely adapt to axial movement, thereby effectively avoiding stress concentration or structural damage caused by limited axial displacement.

[0047] When the central pipe 3 rotates, the central pipe 3 can drive the driving wheel 1701 on the distributor 13 to rotate synchronously through the docking pipe 10, so that the driving wheel 1701 can drive a driving wheel 1704 to rotate in the same direction through the first transmission belt 1708. At this time, the driving wheel 1704 can drive a driving bevel gear 1706 to rotate synchronously through the reciprocating screw 1705. Through the meshing action of the two driving bevel gears 1706 and the driven bevel gear 1707, the other driving wheel 1704 can rotate in the opposite direction, so that the other driving wheel 1704 can drive the driven ring wheel 1712 to rotate through the second transmission belt 1714, which is beneficial for the driven ring wheel 1712 to drive the gas detector 1713 to rotate synchronously during the rotation process, so that the rotation direction of the gas detector 1713 is opposite to the rotation direction of the central pipe 3, thereby further improving the detection efficiency of the gas detector 1713.

[0048] When the reciprocating screw 1705 rotates, the slide 1801 on the reciprocating screw 1705 can be moved back and forth laterally. The lateral reciprocating movement of the slide 1801 can alternately drive the corresponding two driving airbags 1805 to operate, so that the driving airbag 1805 continuously supplies air to the driven airbag 1810 through the one-way air pipe. The volume expansion of the driven airbag 1810 under the action of the airflow can push the force ring 1808 to move laterally, so that the force ring 1808 can drive the transmission ring 1811 to move synchronously through the slide rod 1807, which is beneficial for the transmission ring 1811 to drive the gas detector 1713 to move to the joint between the central pipe 3 and the connecting flange 16 through the connecting rod 1812.

[0049] When the burner 2 is operating, the electric ejector rod 1903 can control the pressing plate 1904 to press against the rotating shaft 1703, so that the rotating shaft 1703 can drive the rotating column 1902 to rotate synchronously through the electric ejector rod 1903. When the rotating column 1902 rotates, through the extrusion force of the curved track 1905 on the drive shaft 1910, the drive shaft 1910 can be moved along the curved track 1905 into the annular track 1906, so that the drive shaft 1910 can drive the slider 1909 to move in the slide track 1908, so that the slider 1909 can drive the support block 1912 to closely adhere to the feeding port 12 through the linkage rod 1911, forming continuous support of the support block 1912 for the feeding port 12, which can prevent the feeding port 12 from being damaged under axial movement. When the burner 2 is shut down, the electric ejector rod 1903 can control the pressing plate 1904 to disengage from the rotating shaft 1703, so that under the elastic force of the support spring piece 1913, the support block 1912 can be driven to disengage from the feeding port 12, which is beneficial to the drive shaft 1910 being able to move back from the annular track 1906 into the curved track 1905, and is beneficial to the subsequent use of the support block 1912.
