Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a variable multi-angle swirler. Background Art

[0002] The swirler, also known as the swirl generator, is a component installed on the burner to rotate the airflow and form a rotating jet. The Chinese utility model patent with the authorization announcement number CN217356865U discloses a burner head swirler for improving the quality of clinker, which relates to the field of cement clinker processing auxiliary equipment. The patent includes an inner swirl column, the outer wall of which is provided with an inclined first ventilation groove that runs through the upper and lower ends of the inner swirl column, and the first ventilation groove is inclined at 35° to achieve the purpose of improving the flame quality and improving the quality of clinker.

[0003] In the prior art, such as the above-mentioned patent, the cyclone of the cyclone is mainly to open an inclined wind slot to achieve the function of generating a swirl. However, in actual work, taking a pulverized coal burner as an example, when the calorific value and fine particle size of the pulverized coal change, the air volume and wind direction need to be adjusted. At this time, the staff needs to replace the cyclone based on experience to adjust the swirl wind direction, and then adjust the flame by adjusting the air volume and other operations to make the burner reach the best state. In this process, the cyclone needs to be replaced and adjusted many times, which is labor-intensive and time-consuming for the staff. Utility Model Content

[0004] The utility model aims to provide a variable multi-angle cyclone, which has the effect of being able to adjust the cyclone angle and convenient to adjust.

[0006] By adopting the above technical solution, the locking mechanism is unlocked, the threaded sleeve is rotated, and the swirl injection tube is tilted under the drive of the second mounting part until it is adjusted to the required position. The locking mechanism locks the position of the threaded sleeve, thereby fixing the inclination angle of the swirl injection tube.

[0007] The swirl injection tube is movably connected to the second mounting portion, so that when the swirl injection tube is tilted, the end portion thereof will not be twisted by the second mounting portion.

[0008] The utility model is further configured as follows: the first mounting portion is ring-shaped.

[0009] A further setting of the present utility model is that: the second mounting portion is annular, a plurality of first through holes are provided on the second mounting portion, spherical grooves are formed at the first through holes, a spherical portion is formed at the end of the swirl injection pipe, and the spherical portion is embedded in the spherical groove.

[0010] By adopting the above technical solution, the spherical portion of the swirl injection pipe is embedded in the spherical groove of the second mounting portion, realizing the movable connection between the swirl injection pipe and the second mounting portion.

[0011] A further setting of the present utility model is that: the swirl injection pipe is a corrugated pipe.

[0012] By adopting the above technical solution, the swirl injection pipe has a certain deformation ability, and the swirl injection pipe will not be pulled off during the adjustment of the inclination angle.

[0013] A further setting of the present utility model is that: the swirl injection pipe is a metal corrugated pipe.

[0014] A further setting of the present utility model is that: a plurality of first through holes are provided on the first mounting portion, the swirl injection pipe passes through the first through holes, a blocking portion is provided at the end of the swirl injection pipe, a rubber sleeve is sleeved on the swirl pipe, and the rubber sleeve is located between the blocking portion and the first mounting portion.

[0015] By adopting the above technical solution, during the adjustment of the inclination angle of the swirl injection pipe, the rubber sleeve can also deform, which can not only provide a certain buffer distance, but also ensure that the swirl injection pipe is still in a straight state after the adjustment is completed.

[0016] A further setting of the present utility model is that: the material of the rubber sleeve is high-temperature resistant rubber.

[0017] A further setting of the present utility model is that: the number of the rubber sleeves is one or more.

[0018] By adopting the above technical solution, the staff can select the number of rubber sleeves according to the actual situation and needs.

[0019] A further setting of the present utility model is that: the blocking portion is annular, and the blocking portion is threadedly connected to the swirl injection pipe.

[0020] By adopting the above technical solution, rotating the blocking portion can remove it from the swirl injection pipe to replace the rubber sleeve.

[0021] The further setting of the present utility model is as follows: The locking mechanism includes a first seat body fixed on the outer wall of the threaded sleeve, and two second seat bodies fixed on the outer wall of the cyclone body. The first seat body is located between the two second seat bodies. A locking bolt is threadedly connected to each second seat body, and the locking bolt abuts against the first seat body.

[0022] By adopting the above technical solution, the two locking bolts respectively abut against both ends of the first seat body, so as to lock the positions of the first seat body and the threaded sleeve. Rotating the two locking bolts to disengage them from the first seat body can unlock the positions of the first seat body and the threaded sleeve.

[0023] The beneficial effect of the present utility model is that the present utility model realizes the locking and unlocking of the position of the threaded sleeve through the locking mechanism. When the threaded sleeve is unlocked, rotating the threaded sleeve can adjust the inclination angle of the swirl injection pipe relative to the central axis of the cyclone body, so as to adjust the swirl direction. When adjusting the swirl wind direction, there is no need to replace the cyclone on the burner, which greatly reduces the labor intensity and time consumption of the operators.
