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; The distributor is equipped with a driving wheel, and two fixing plates are symmetrically installed on the fixing seat, and a rotating shaft is rotatably installed on the two fixing plates, and a transmission wheel is installed at the opposite ends of the two rotating shafts, and a reciprocating screw is installed at the center of the end of the transmission wheel away from the rotating shaft, and a transmission bevel gear is installed at the other end of the reciprocating screw, and a driven bevel gear is installed on the fixing seat, and the two transmission bevel gears are meshed with the driven bevel gear. A first transmission belt is sleeved on the driving wheel and a transmission wheel, and a fixing ring is fixedly installed on the side of the burner close to the connecting flange, and a swivel is rotatably installed in the fixing ring, a linkage rod is installed on the swivel, and a driven ring wheel is installed on the linkage rod, and a second transmission belt is sleeved on the driven ring wheel and another transmission wheel. A gas detector is arranged on the driven ring wheel. When the central pipe rotates, the central pipe can drive the driving wheel on the distributor to rotate synchronously through the docking pipe, so that the driving wheel can drive a driving wheel to rotate in the same direction through the first transmission belt. At this time, the driving wheel can drive a driving bevel gear to rotate synchronously through the reciprocating screw. Through the meshing action of the two driving bevel gears and the driven bevel gear, the other driving wheel can rotate in the opposite direction, so that the other driving 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 the rotation process, so that the rotation direction of the gas detector and the rotation direction of the central pipe are opposite to each other, thereby further improving the detection efficiency of the gas detector.

[0008] As a preferred technical solution, the rotary compound stage utilization assembly includes a slide seat, a transmission rod, an extrusion plate, a bottom plate, a driving airbag, a sliding hole, a sliding rod, a force ring, a connecting ring, a driven airbag, a transmission ring and a connecting rod; A slide seat is slidably mounted on the two reciprocating screws, a transmission rod is mounted on the slide seat, an extrusion plate is mounted on the transmission rod, two groups of base plates are symmetrically mounted on the fixed seat, the two sides of the extrusion plate are respectively connected with the two base plates in one group through a driving airbag, a sliding hole is opened on the driven ring wheel, a slide rod is slidably mounted in the sliding hole, a force ring is mounted on the end of the slide rod close to the fixed ring, a connecting ring is rotatably mounted on the force ring, the connecting ring is connected to the fixed ring through the driven airbag, the input end of the driven airbag is connected to the output end of the driving airbag through a one-way air pipe, and a transmission ring is mounted on the other end of the slide rod. A connecting rod is installed on the transmission ring, and a gas detector is installed on the connecting rod. When the reciprocating screw rotates, the slide on the reciprocating screw can be moved back and forth laterally. The lateral reciprocating movement of the slide can alternately drive the corresponding two driving airbags to operate, so that the driving airbag continuously supplies air to the driven airbag through the one-way air pipe. The volume expansion of the driven airbag under the force of the airflow can push the force ring to move laterally, so that the force ring can drive the transmission ring to move synchronously through the slide rod, which is beneficial for the transmission ring to drive the gas detector to move to the joint between the central pipe and the connecting flange through the connecting rod.

[0009] As a preferred technical solution, a one-way suction pipe is installed on the input end of the driving airbag, and a pressure-stabilizing valve and an exhaust valve are installed on the output end of the driven airbag. The setting of the pressure-stabilizing valve can ensure that the driven airbag continues to maintain an inflated state and can also prevent the driven airbag from rupturing. The connecting ring and the fixed ring are connected by an elastic band. Through the setting of the exhaust valve, after the exhaust valve is opened, the force ring can be driven to move back and reset under the tension of the elastic band.

[0010] As a preferred technical solution, the support assembly includes a connecting plate, a rotating column, an electric push rod, a tightening plate, a curved track, a ring track, a fixed block, a slideway, a slider, a driving shaft, a linkage rod and a support block; 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 push rod is installed on the end of the rotating column near the fixed plate, a tightening plate is installed on the electric push rod, a curved path and a ring path are arranged on the rotating column, the curved path is connected with the ring path, a fixing block is installed on the fixed seat, a slideway is provided on the fixing block, a slider is slidably installed in the slideway, a driving shaft is installed on the upper end of the slider, the driving shaft slides and is inserted in the curved path, a connecting rod is installed on the lower end of the slider, A support block is installed. When the burner is running, the electric push rod can control the top clamping plate to be close to the rotating shaft, so that the rotating shaft can drive the rotating column to rotate synchronously through the electric push rod. When the rotating column rotates, the squeezing force of the curved path on the driving shaft can make the driving shaft move along the curved path into the ring path, so that the driving shaft can drive the slider to move in the slideway, so that the slider can drive the support block to be close to the feeding port through the connecting rod, forming continuous support for the feeding port by the support block, which can avoid damage to the feeding port due to axial movement.

[0011] As a preferred technical solution, the electric push rod is electrically connected to the burner, and the central pipe rotates counterclockwise.

[0012] As a preferred technical solution, the inner wall of the ring on one side of the ring channel close to the curved channel is threaded, and the fixed rod is connected to the connecting rod by a supporting spring. When the burner stops operating, the electric push rod can control the tightening plate to disengage from the rotating shaft, so that under the elastic force of the supporting spring, the support block can be driven to disengage from the feeding port, which is conducive to the drive shaft being moved from the ring channel back to the curved channel, and is conducive to the subsequent use of the support block.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When radial runout or axial movement occurs in the central pipe, the slide plate can slide on the vertical rod and compress the buffer spring during movement. The elastic deformation of the buffer spring can be used to absorb and eliminate the radial runout of the central pipe during operation, ensuring that the equipment maintains stability under vibration or impact. The sliding bearings set at the connection of the central pipe 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.

[0014] The present application sets up a rotating primary utilization component, which can make the central pipeline drive the driving wheel to rotate synchronously, and the driving wheel drives a transmission wheel to rotate in the same direction. Then, through the meshing action of the two transmission bevel teeth and the driven bevel teeth, the reverse rotation of the other transmission wheel can be achieved, so that the other transmission wheel drives 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 the rotation process, so that the rotation direction of the gas detector and the rotation direction of the central pipeline are opposite to each other, thereby further improving the detection efficiency of the gas detector.

[0015] The present application sets up a rotary compound utilization component, which can alternately drive the corresponding two driving airbags to operate by utilizing the lateral reciprocating movement of the slide seat, so that the driving airbag continuously supplies air to the driven airbag through the one-way air pipe, allowing the driven airbag to push the force ring to move laterally, which is beneficial for the transmission ring to drive the gas detector to move to the joint between the central pipe and the connecting flange.

[0016] The support assembly set up in the present application can allow the rotating shaft to drive the rotating column to rotate synchronously through the electric push rod, and can allow the driving shaft to move along the curve into the ring track, so that the driving shaft can drive the slider to move in the slideway, and the slider can drive the support block to be close to the feed port through the connecting rod, forming continuous support for the feed port by the support block, which can prevent the feed port from being damaged due to axial movement.

When the burner 2 is running, the electric top rod 1903 can control the tightening plate 1904 to be close to the rotating shaft 1703, so that the rotating shaft 1703 can drive the rotating column 1902 to rotate synchronously through the electric top rod 1903. When the rotating column 1902 rotates, the squeezing force of the curved path 1905 on the driving shaft 1910 can make the driving shaft 1910 move along the curved path 1905 into the annular path 1906, so that the driving shaft 1910 can drive the slider 1909 to move in the slideway 1908, so that the slider 1909 can drive the support block 1912 to be close to the feed port 12 through the connecting rod 1911, so that the support block 1912 continuously supports the feed port 12, which can prevent the feed port 12 from being damaged due to axial movement.

[0028] Working principle of the present invention: 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.

[0029] 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.

[0030] 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.

[0031] When the burner 2 is running, the electric push rod 1903 can control the top plate 1904 to be close to the rotating shaft 1703, so that the rotating shaft 1703 can drive the rotating column 1902 to rotate synchronously through the electric push rod 1903. When the rotating column 1902 rotates, the squeezing force of the curved path 1905 on the driving shaft 1910 can make the driving shaft 1910 move along the curved path 1905 into the annular path 1906, so that the driving shaft 1910 can drive the slider 1909 to move in the slideway 1908, so that the slider 1909 can be moved through the linkage rod 1911 The support block 1912 is driven to be close to the feed port 12, so that the support block 1912 continuously supports the feed port 12, which can prevent the feed port 12 from being damaged due to axial movement. When the burner 2 stops operating, the electric push rod 1903 can control the tightening plate 1904 to separate from the rotating shaft 1703, so that under the elastic force of the supporting spring 1913, the support block 1912 can be driven to separate from the feed port 12, which is conducive to realizing that the drive shaft 1910 can be moved from the ring channel 1906 back to the curved channel 1905, which is conducive to the subsequent use of the support block 1912.
