The main gas supply pipe 5a is mounted on the frame 1 or mounted on the cross rail 11, so that gas can be supplied to the plurality of gas heads 51. The control valve 5b may be a solenoid valve for remote control.

Referring to fig. 1 to 4, in the present application, the gas head 51 can rotate when the gas hose 52 supplies the pressure gas, which is mainly for rotating the gas head 51, the gas outlet end of the gas head 51 is disposed obliquely outward in the present application, that is, the direction of the sprayed gas is not parallel to the axial direction of the nozzle 53, and for this reason, the flame formed after the combustion of the gas sprayed from the gas head 51 at the later stage is not the same as the direction of the nozzle 53, so that the gas can be sprayed all-directionally, and especially the flame can enter the corner area of the mold to be baked. In order to realize the automatic rotation or passive rotation of the gas head 51, the gas head 51 comprises a rotating cylinder 511 and a plurality of nozzles 512, the outward end of the rotating cylinder 511 is closed, the plurality of nozzles 512 are obliquely and outwardly communicated with the outward end of the rotating cylinder 511, a neck 513 is arranged in the rotating cylinder 511, the diameter of the neck 513 is smaller than that of the two ends of the rotating cylinder 511, the neck 513 is movably sleeved on the outer wall of the air outlet end of the spray head 53 through a rotating ring frame 514, and the inner wall of the non-closed end of the rotating cylinder 511 is provided with a spiral rifling 515 or a spiral blade along the axial direction. Since the air outlet end of the nozzle 53 is disposed in the neck 513, the air flow rate in the neck 513 is significantly higher than the air flow rate outside, and according to bernoulli's principle, the pressure at the neck 513 is the smallest, and the neck 513 is a negative pressure region with respect to the atmospheric pressure outside and the pressure of the pressurized gas in the nozzle 53. Therefore, after the spray nozzle 53 sprays the pressure gas, outside air is inevitably driven to enter the rotating cylinder 511 from the unclosed end of the rotating cylinder 511, and finally the air and the pressure gas sprayed by the spray nozzle 53 are mixed and sprayed out from the nozzle 512, so that the outside ignition is facilitated. Since continuous air enters the rotary drum 511 from the unclosed end of the rotary drum 511, the flowing air flow interacts with the spiral rifling 515 or the spiral blades, so that the air flow provides a collision force to the spiral rifling 515 or the spiral blades, and when the speed of the pressure gas sprayed from the spray head 53 is high enough, that is, the negative pressure in the region of the neck 513 is low enough, the air flow pushes the rotary drum 511 to overcome the friction force between the rotary drum 511 and the spray head 53 to realize relative rotation. Due to the structural design, flame columns formed by the ignited combustible mixed gas sprayed by the spray nozzles 512 can rotate around the axial direction of the spray head 53, or form a certain included angle with the axial direction of the spray head 53, so that various special-shaped concave areas in the crystallizer can be conveniently baked, and the baking quality is improved.

As an improvement of the above technical solution, in order to reduce the trouble of manual ignition, an ignition rod 54 is coaxially arranged at the outward end of the spray head 53, the outward end of the ignition rod 54 movably penetrates through the closed end of the rotary cylinder 511, and an igniter 55 is arranged at the tail end of the ignition rod 54. The igniter 55 may be angled with respect to the ignition rod 54 such that the ignition end of the igniter 55 is adjacent the nozzle 512 for ignition purposes. In this embodiment, a sealing structure is provided between the outer wall of the ignition rod 54 and the closed end of the rotary cylinder 511 to realize the rotary sealing. While the igniter 55 can be routed within the spray head 53 and eventually out through the spray head 53 or the side wall of the gas hose 52 to communicate with external circuitry.

Referring to fig. 3 and 4, in order to better limit the position of the rotary cylinder 511 on the spray head 53, the output end of the spray head 53 is provided with a mounting step 56, the spray head 53 limits the rotary ring bracket 514 on the mounting step 56 through a locking nut 57, and the mounting step 56 is provided with a rotary bearing.

Referring to fig. 4, in the above embodiment, the aperture of the nozzle 53 is a fixed aperture, which is not suitable for baking of crystallizers of different specifications and is not beneficial to adjusting the flow rate of the pressure gas. In a modified embodiment of the present application, a cone 58 is disposed on the outer wall of the output end of the spray nozzle 53, a plurality of open slots 581 are uniformly disposed on the side wall of the cone 58 along the axial direction thereof, and the end of the spray nozzle 53 is divided into a plurality of tongues 582; the outer wall of one end of the spray head 53 close to the cone nozzle 58 is connected with an adjusting mechanism 59 through threads, the adjusting mechanism 59 can adjust the caliber of the output end of the cone nozzle 58, and the caliber of the output end of the cone nozzle 58 adjusted by the adjusting mechanism 59 is actually the closing caliber of the cone nozzle 58 formed by all the tongues 582.

Further, in order to simplify the structure and facilitate the adjustment, the adjusting mechanism 59 includes an adjusting nut 591, a limiting ring 592 and a connecting rod 593, the connecting rod 593 is provided with a plurality of groups, two ends of the plurality of groups of connecting rods 593 are respectively connected with the adjusting nut 591 and the limiting ring 592, the adjusting nut 591 is screwed on the outer wall of one end of the spray head 53 close to the cone nozzle 58, and the limiting ring 592 is movably sleeved on one end of the output of the cone nozzle 58. When the caliber of the output end of the conical nozzle 58 needs to be adjusted to be small, the limiting ring 592 moves along the conical nozzle 58 close to one end of the spray head 53 by rotating the adjusting nut 591, so that the tongue pieces 582 can be pressed to draw close inwards, the air outlet caliber of the conical nozzle 58 formed by all the tongue pieces 582 becomes small, and the effects of closing up and adjusting the flow rate of pressure gas sprayed by the spray head 53 are achieved. In fact, in some improved embodiments, the size of the flame column sprayed out by the nozzle 512 is adjusted to adapt to the drying work of crystallizers with different specifications. The nozzle 512 may also be provided with an adjustment mechanism 59 and a cone 58 to achieve the same effect as the spray head 53, which will not be described in detail herein.
