Technical Field

[0001] The present invention relates to the technical field of burners, and in particular to a boiler burner and a use method thereof. Background Art

[0002] The pre-chamber injection of the boiler burner is a preventive measure taken to prevent coking in the pre-chamber. By injecting the bottom of the pre-chamber once every one or two minutes, the unburned coal powder and coal slag particles that have settled to the bottom are blown out in time to prevent coking due to long-term burning under high temperature.

[0003] An existing boiler burner (Announcement No.: CN219640258U) has at least the following disadvantages: when the device uses a blower to input airflow to the burner, the airflow can only be regulated by controlling the speed of the blower. However, directly reducing the speed to reduce the airflow will also synchronously cause the airflow velocity to slow down, thereby affecting the normal operation of the burner. For this reason, the present invention is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a boiler burner and a method of using the same.

The clamping cylinder close to the blower is fixed at the air outlet of the blower, and the clamping cylinder close to the burner body is fixed at the air inlet of the burner body. A clamping groove is provided on the inner wall of the clamping cylinder, and the clamping ring is slidably arranged with the outer wall of the clamping groove. A gear ring is fixed on the outer wall of the adjusting cylinder, and a first gear, a second gear and a third gear are respectively arranged above the connecting seat from front to back.

[0008] As a further solution of the present invention, the diameter ratio of the first gear to the gear ring is two to one, the diameter ratio of the first gear to the gear ring is four to one, and the diameter ratio of the third gear to the gear ring is eight to one.

[0009] As a further solution of the present invention, a driving frame is fixed to the top surface of the connecting seat, and the internal rotation of the driving frame is connected to the driving rod. A driving motor is fixed to the rear side of the driving frame, and the output shaft end of the driving motor is fixed to the rear end of the driving rod. Three driving gears are fixed to the outer wall of the driving rod, and the front sides of the first gear, the second gear and the third gear are all fixed with driven gears, and the driving gear and the driven gear are driven by toothed belt meshing.

[0010] As a further solution of the present invention, a support frame is fixed between the burner body and the blower, and three driven gears are respectively rotatably connected to one side of the support frame.

[0011] As a further solution of the present invention, an oxygen tank is fixed on the top surface of the blower, a bleed valve is installed at the front end of the oxygen tank, a delivery pipe is fixed at the air outlet end of the bleed valve, and the front end of the delivery pipe is connected and fixed to the rear end of the burner body.

[0012] As a further solution of the present invention, the shock absorbing mechanism includes a mounting base arranged below the connecting seat, two shock absorbing frames are fixed on the top surface of the mounting base, a fixing rod is fixed inside the shock absorbing frame, two sliding plates are slidably arranged on the outer wall of the fixing rod, a spring and a damper are respectively fixed between the sliding plate and the inner side of the shock absorbing frame, the spring is movably sleeved on the outer wall of the fixing rod, the top surface of the sliding plate is rotatably connected with a linkage rod, two rotating seats are fixed on the bottom surface of the connecting seat, and four linkage rods are rotatably connected to the front and rear ends of the two rotating seats respectively.

[0013] As a further solution of the present invention, mounting plates are fixed on both left and right sides of the top surface of the mounting base, and mounting holes are opened on the top surface of the mounting plates.

[0014] As a further solution of the present invention, limiting rods are fixed at the four corners of the bottom surface of the connecting seat, and limiting cylinders are fixed at the four corners of the top surface of the mounting base, and the limiting rods are slidably inserted into the interior of the limiting cylinders.

[0015] A method for using a boiler burner comprises the following steps:

[0016] S1: Install the burner body and the boiler, then install the mounting base at the working point by inserting bolts into the mounting holes to complete the arrangement of the device, then start the blower to generate airflow and input it into the inside of the regulating cylinder, then the airflow passes through three sets of parallel fins and inputs into the inside of the burner body, then start the burner body for operation.

[0017] S2: When the air flow of the blower needs to be adjusted, the drive motor is started to drive the drive rod to rotate, and the drive gear is driven to rotate. Under the action of the toothed belt meshing transmission between the drive gear and the driven gear, the first gear, the second gear and the third gear rotate synchronously, thereby driving the three gear rings to rotate respectively. When the diameter ratio of the first gear to the gear ring is two to one, the diameter ratio of the first gear to the gear ring is four to one, and the diameter ratio of the third gear to the gear ring is eight to one, after the first gear, the second gear and the third gear rotate one circle synchronously, the three gear rings and the adjusting cylinder rotate one half circle, one quarter circle and one eighth circle respectively, so that the fins inside the three adjusting cylinders cross each other, thereby reducing the air volume passing through the adjusting cylinder, while ensuring that the wind speed will not decrease, thereby ensuring the normal operation of the burner.

[0018] S3: When the blower and the burner body generate vibration during operation, the connecting seat vibrates up and down as a whole and causes the linkage rod to rotate on the rotating seat, thereby pushing the sliding plate to slide on the outer wall of the fixed rod and compressing the spring. At this time, the spring limits the sliding of the sliding plate on the outer wall of the fixed rod, thereby absorbing the vibration generated by the operation of the blower and the burner body, and then the damper has a damping effect on the spring.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By setting three adjusting cylinders and arranging a plurality of fins inside the adjusting cylinders, when it is necessary to adjust the amount of airflow input into the burner body, the three adjusting cylinders are rotated so that the three groups of fins inside the three adjusting cylinders are crossed, so that the flow gap between the fins is reduced, thereby realizing the adjustment of the air volume input into the burner body, and the fins are arranged parallel to the direction of airflow movement, which effectively reduces the direct impact of the airflow on the side of the fin, prevents the fin from deformation and damage, and increases the service life of the device.

[0021] By arranging the fins parallel to the direction of airflow movement, a narrower airflow channel with a longer stroke is formed when the three groups of fins cross, thereby effectively increasing the airflow velocity, so that the blower can ensure a higher airflow velocity when outputting a lower airflow volume, thereby ensuring the normal operation of the burner.

[0022] When the blower and the burner body generate vibration during operation, the connecting seat vibrates up and down as a whole and causes the linkage rod to rotate on the rotating seat, thereby pushing the sliding plate to slide on the outer wall of the fixed rod and compressing the spring. At this time, the spring limits the sliding of the sliding plate on the outer wall of the fixed rod, thereby absorbing the vibration generated by the operation of the blower and the burner body, and then the damper has a damping effect on the spring.

Under the action of the toothed belt meshing transmission between the driving gear 303 and the driven gear 304, the first gear 207, the second gear 208 and the third gear 209 rotate synchronously, thereby driving the three gear rings 206 to rotate respectively. When the diameter ratio of the first gear 207 to the gear ring 206 is two to one, the diameter ratio of the first gear 207 to the gear ring 206 is four to one, and the diameter ratio of the third gear 209 to the gear ring 206 is eight to one, after the first gear 207, the second gear 208 and the third gear 209 rotate synchronously for one circle, the three gear rings 206 and The regulating cylinder 201 rotates one half, one quarter and one eighth of a circle respectively, so that the fins 202 inside the three regulating cylinders 201 cross each other, thereby reducing the air volume passing through the regulating cylinder 201, while ensuring that the wind speed will not be reduced, thereby ensuring the normal operation of the burner. When the blower 102 and the burner body 101 vibrate during operation, the connecting seat 1 vibrates up and down as a whole and causes the linkage rod 605 to rotate on the rotating seat 606, thereby pushing the sliding plate 603 to slide on the outer wall of the fixed rod 602 and compressing the spring 604. At this time, the spring 604 limits the sliding plate 603 on the fixed rod 602. The sliding of the outer wall can absorb the vibration generated by the operation of the blower 102 and the burner body 101, and then the damper 607 can damp the spring 604. By setting the oxygen tank 5, when the oxygen content of the air input by the blower 102 to the burner body 101 is not enough to ensure the complete combustion of the oil mist inside the burner body 101, the air release valve 501 can be opened to supplement oxygen to the burner body 101, so as to ensure the complete combustion of the oil mist inside the burner body 101 and reduce the generation of harmful gases due to incomplete combustion. The limiting rod 8 can limit and support the connecting seat 1.
