Description

Technical Field

[0001] This utility model relates to the field of rotary kilns, and more specifically, to a rotary kiln dispersion combustion device. Background Technology

[0002] In the field of rotary kilns, as an important thermal equipment, rotary kilns are widely used in industries such as cement, metallurgy, and chemicals for processes such as heating and calcining materials. Through the rotation of the kiln body, the materials are continuously tumbled and moved within the kiln, achieving uniform heating and reaction. The combustion device, as a key component of the rotary kiln, directly affects the combustion efficiency and temperature distribution within the kiln. The emergence of rotary kiln dispersion combustion devices aims to provide a more efficient and stable combustion method for rotary kilns.

[0003] The nozzles of existing rotary kiln dispersion combustion devices are usually connected by threaded tightening and multi-part nested clamping, which is a complex installation structure. During long-term operation of the rotary kiln, the nozzles are prone to wear and blockage, requiring frequent replacement. The complex structure greatly increases the difficulty of replacement, seriously reduces equipment maintenance efficiency, leads to production process obstruction, significantly increases labor and time costs, and raises the overall production cost.

[0004] Furthermore, during the operation of a rotary kiln, different stages of material calcination require different air intake volumes to achieve optimal combustion and temperature control. However, the existing rotary kiln combustion device's air intake adjustment mechanism is not flexible enough, making it difficult to precisely adjust the air intake volume according to actual needs. This may lead to incomplete combustion within the kiln, resulting in energy waste, or uneven temperature distribution, affecting the calcination quality of the material.

[0005] Therefore, we have made improvements to this by proposing a rotary kiln dispersion combustion device. Utility Model Content

[0035] To address the technical problems in the background art, the following rotary kiln dispersion combustion device is provided:

[0036] Combination Figure 1 - Figure 6 As shown, the rotary kiln dispersion combustion device provided by this utility model includes a heat insulation sleeve 1. A nozzle 2 is provided inside one end of the heat insulation sleeve 1, and an oil cavity 3 is opened in the middle of the surface of the nozzle 2. Multiple nozzles 4 are installed on the surface of the nozzle 2, and a connecting mechanism 5 is provided between the nozzles 4 and the nozzle 2. An air inlet adjustment mechanism 6 is provided on the outside of the heat insulation sleeve 1. The connecting mechanism 5 includes a mounting groove 501, which is opened on the front surface of the nozzle 2. A number of mounting holes 502 are opened on the surface of the mounting groove 501, and the nozzles 4 are connected to the mounting holes 502 by a snap-fit ​​connection. A retaining ring 503 is snapped inside the mounting groove 501, and a number of holes 504 are opened on the surface of the retaining ring 503. The diameter of the holes 504 is smaller than the diameter of the nozzles 4.

[0037] In this embodiment: The nozzle 2 inside one end of the insulation sleeve 1 has an oil cavity 3 in the middle of its surface for fuel flow. Multiple nozzles 4 on the nozzle 2 are conveniently installed through a connecting mechanism 5. The nozzles 4 are engaged with the mounting holes 502.

The insulation sleeve 1 is provided with an air intake adjustment mechanism 6. This design makes the device more advantageous in terms of nozzle replacement and air intake adjustment, ensuring efficient and stable combustion in the rotary kiln.

[0038] In a preferred embodiment, slots 505 are provided around the inner wall of the mounting groove 501, and a locking block 506 is slidably connected inside the slot 505.

Slots 508 are provided around the outer surface of the retaining ring 503, and the slots 508 and the locking block 506 are connected by a snap-fit ​​connection.

[0039] In this embodiment: the inner wall of the mounting groove 501 has slots 505 around its perimeter, and the internal sliding connection of the locking block 506 can be held in place by the elastic force of the spring 507. When the retaining ring 503 is inserted into the mounting groove 501, the locking block 506 will be inserted into the corresponding slot 508 on the outer surface of the retaining ring 503, achieving a stable locking connection.

[0040] In a preferred embodiment, a connecting groove 509 is provided on one side surface of the slot 505, and a connecting rod 510 is slidably connected inside the connecting groove 509. The connecting rod 510 is fixedly connected to the locking block 506, and a push block 511 is fixedly installed on one side surface of the connecting rod 510.

[0041] In this embodiment: the connecting groove 509 opened on one side surface of the slot 505 provides sliding space for the internal components. The connecting rod 510 slides in the connecting groove 509, and because it is fixedly connected to the locking block 506, it can drive the locking block 506 to move synchronously. The push block 511 fixed on the connecting rod 510 provides the operator with a convenient point of force application, which makes it easy to push the locking block 506 out of the slot 508 to remove the retaining ring 503, making the nozzle replacement operation simpler.

[0042] In a preferred embodiment, the air intake adjustment mechanism 6 includes a fixed cover 601, which is fixedly installed on the outside of the insulation sleeve 1.

[0043] In this embodiment: the fixed cover 601 of the air intake adjustment mechanism 6 is securely installed on the outside of the insulation sleeve 1, providing support and protection for the internal adjustment components; the connecting ring 602 set inside the insulation sleeve 1 serves as the rotation base point, and the raw material pipeline for combustion of the device can pass through the connecting ring 602. The rotating rod 603 rotates flexibly on its outer surface, thereby driving the fixedly installed rotating blade 604 to rotate, thus realizing the initial adjustment of the air intake volume and creating conditions for subsequent precise adjustment of the air intake volume.

[0044] In a preferred embodiment, the other end of the rotating rod 603 extends out of the outside of the insulation sleeve 1, and an installation rod 605 is fixedly installed on the surface of the other end of the rotating rod 603. A sliding groove 606 is provided on the surface of the installation rod 605, and a rotating ring 607 is provided on one side of the installation rod 605. A fixing rod 608 is fixedly installed on the outer surface of the rotating ring 607, and the fixing rod 608 is slidably connected to the sliding groove 606.

[0045] In this embodiment: by rotating the rotating ring 607, the fixed rod 608 can slide in the slide groove 606, thereby driving the mounting rod 605 to rotate, and driving the rotating rod 603 and the rotating blade 604 on the surface to rotate, thereby adjusting the air intake volume.

[0046] In a preferred embodiment, a connector 609 is fixedly installed on the outside of the insulation sleeve 1, and a guide wheel 610 is rotatably connected inside the connector 609, with the rotating ring 607 rotating inside the guide wheel 610.

[0047] In this embodiment, the guide wheel 610 can limit the rotation ring 607 to ensure that the rotation ring 607 remains stable during rotation and avoids it from deviating or shaking, thereby ensuring the smoothness and accuracy of the operation of the air intake adjustment mechanism 6.

[0048] In a preferred embodiment, the inner wall of the rotating ring 607 is provided with a plurality of toothed grooves 611, a motor 612 is fixedly installed on the surface of the insulation sleeve 1, and a gear 613 is fixedly connected to the output end of the motor 612, and the gear 613 meshes with the plurality of toothed grooves 611.

[0049] In this embodiment: when the motor 612 starts, it can drive the rotating ring 607 to rotate precisely and stably through the meshing transmission of the gear 613 and the tooth groove 611, thereby driving the entire air intake adjustment mechanism 6 to operate, realizing precise adjustment of the air intake volume, and effectively improving the automation level and combustion efficiency of the rotary kiln dispersion combustion device.

[0050] Specifically, the working principle of this solution is as follows:

[0051] During use, fuel flows through the oil chamber 3 on the surface of the nozzle 2 and is then sprayed out through multiple nozzles 4 for combustion. The nozzles 4 are connected to the nozzle 2 via a connecting mechanism 5. During installation, the nozzle 4 is inserted into the mounting hole 502 on the surface of the mounting groove 501, and then the retaining ring 503 is inserted into the mounting groove 501. The locking block 506 in the groove 505 on the inner wall of the mounting groove 501 is locked into the locking groove 508 on the outer surface of the retaining ring 503 under the elastic force of the spring 507, achieving a stable connection. During disassembly, the push block 511 is pushed, and the locking block 506 is disengaged from the locking groove 508 through the connecting rod 510, so that the retaining ring 503 and the nozzle 4 can be removed. The operation is simple.

[0052] For air intake regulation, the motor 612 outside the insulation jacket 1 starts, and the gear 613 at its output end meshes with the toothed groove 611 on the inner wall of the rotating ring 607, driving the rotating ring 607 to rotate stably within the guide wheel 610. The fixing rod 608 on the outer surface of the rotating ring 607 slides within the sliding groove 606 on the surface of the mounting rod 605, causing the mounting rod 605 to rotate, which in turn causes the rotating rod 603 to rotate on the connecting ring 602, ultimately driving the rotating blade 604 to rotate, thereby regulating the air intake. The guide wheel 610 acts as a limit for the rotating ring 607, ensuring its stable operation and preventing deviation or shaking. This design effectively improves the automation level and combustion efficiency of the device, ensuring efficient and stable combustion within the rotary kiln.

[0053] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
