[0038] Example

[0039] In order to solve the problem that the heater used to heat the flute tip in the prior art cannot be adjusted in height and angle, reference is made to Figure 1 As shown, the present application discloses an adjustable steam heating device, comprising: a frame 10;

[0040] Two support frames 20, the two support frames 20 are respectively fixed on both sides of the upper part of the frame 10;

[0041] Two steering gears 30, the two steering gears 30 are respectively fixed on the top of the two supporting frames 20, and the two steering gears 30 are connected by a transmission shaft 50;

[0042] The up-down adjustment motor 40 is arranged above one of the support frames 20 and its output shaft is connected to the steering gear 30 on the support frame 20;

[0043] Two worm gears 60, the two worm gears 60 are respectively connected to the inside of the two steering gears 30 and extend to the upper and lower sides;

[0044] Two inverted L-shaped plates 70, fixing members 80 are obliquely arranged above the two inverted L-shaped plates 70, and the two worms 60 are connected to the two fixing members 80 respectively;

[0045] A steam heater 90, which is disposed between the two inverted L-shaped plates 70 and connected to the two inverted L-shaped plates 70 via a rotating shaft 100;

[0046] When the steam heater 90 is raised and lowered, the up and down adjustment motor 40 drives the transmission shaft 50. At this time, the two rotators will drive the worm 60 to perform the lifting movement. Since the steam heater 90 is connected to two inverted L-shaped plates 70, the steam heater 90 can be raised and lowered.

[0047] A large gear 110, which is disposed outside one of the inverted L-shaped plates 70 and connected to the rotating shaft 100 on the inverted L-shaped plate;

[0048] The small gear 120 is arranged on the same side as the large gear 110 on the outside of one of the inverted L-shaped plates 70, and the small gear 120 is meshingly connected with the large gear 110. A rotating shaft 130 is provided in the small gear 120 and is rotatably connected to the inverted L-shaped plate 70, or a rotating adjustment motor connected to the small gear 120 is provided on the inverted L-shaped plate 70.

[0049] When adjusting the angle of the steam heater 90, the operator can twist the small gear 120 to cooperate with the large gear 110 to drive the steam heater 90 to rotate and adjust, or set a rotation adjustment motor on the inverted L-shaped plate 70 to drive the small gear 120 to rotate and cooperate with the large gear 110 to drive the steam heater 90 to rotate and adjust. In specific implementation, these two methods can be used at will, and the utility model only discloses a schematic diagram of setting a rotating shaft 130 on the inverted L-shaped plate 70.

[0050] In one specific embodiment, guide sleeves 140 are respectively provided inside the two sides of the frame 10, and the bottoms of the two worm gears 60 are respectively connected with guide pillars 150 passing through the guide sleeves 140, and the two guide pillars 150 are respectively fixed to the two fixing members 80. When the two worm gears 60 are lifted and lowered, the guide pillars 150 can be lifted and lowered in the guide sleeves 140, so that the steam heater 90 can be lifted and lowered smoothly.

[0051] The present application may choose that the fixing member 80 is a fixing sleeve, and the guide post 150 is inserted into the interior of the fixing sleeve by interference fit, which is convenient and quick to assemble and has strong practicality.

[0052] As a preferred embodiment of the present application, in order to ensure that the two guide pillars 150 have a strong balancing performance, a balancing rod 160 is connected below the two guide pillars 150 .

[0053] refer to Figure 2-Figure 5 As shown, the following is a structure of a steam heater 90 disclosed in this application:

[0054] The steam heater 90 of the present application includes a heating plate 91, and the interior of the heating plate 91 is sequentially provided with a low-temperature and low-pressure steam section 911, a high-temperature and high-pressure steam section 912 and a steam spray chamber 913 from top to bottom. The low-temperature and low-pressure steam section 911 is communicated with the steam spray chamber 913. The low-temperature and low-pressure steam in the low-temperature and low-pressure steam section 911 is heated by conduction of the high-temperature and high-pressure steam in the high-temperature and high-pressure steam section 912 to form low-pressure and high-temperature steam, which is then buffered in the steam spray chamber 913. A spray orifice plate 92 is installed on the top of the heating plate 91 to spray the low-pressure and high-temperature steam in the steam spray chamber 913 outward. In order to ensure that there is no steam adhesion on the spray orifice plate 20, the upper surface of the spray orifice plate 92 of the present application is coated with an anti-stick coating (not marked in the present application).

[0055] Among them, the low-temperature and low-pressure steam part 911 includes a plurality of low-temperature and low-pressure steam pipes 9111 opened at the lower part of the heating plate 91. Among the plurality of low-temperature and low-pressure steam pipes 9111, the diameters of the two low-temperature and low-pressure steam pipes 9111 on both sides are larger than the diameters of the other low-temperature and low-pressure steam pipes 9111. The middle parts of the plurality of low-temperature and low-pressure steam pipes 9111 are connected with a steam passage 9113. Two low-temperature and low-pressure steam inlets 9112 are arranged on one side of the outside of the heating plate 91, and the two low-temperature and low-pressure steam inlets 9112 are connected to the two low-temperature and low-pressure steam pipes 9111 on both sides. A plurality of steam string holes 914 are opened between the plurality of low-temperature and low-pressure steam pipes 9111 and the steam spray chamber 913.

[0056] Among them, the high-temperature and high-pressure steam section 912 includes a disc-type high-temperature and high-pressure steam pipe 9121 opened above a number of low-temperature and low-pressure steam pipes 9111. The diameter of the disc-type high-temperature and high-pressure steam pipe 9121 is arranged in the form of large on both sides and small in the middle. The outer side of the heating plate 91 is respectively provided with a high-temperature and high-pressure steam inlet 9122 and a high-temperature and high-pressure steam outlet 9123 connected to the two ends of the disc-type high-temperature and high-pressure steam pipe 9121.

[0057] When the low-pressure steam enters several low-pressure steam pipelines from the low-temperature and low-pressure steam inlet 9112, the low-pressure steam will move upward through the steam string hole 914. When the low-pressure steam passes through the disc-type high-temperature and high-pressure steam pipeline 9121, the high-pressure steam in the disc-type high-temperature and high-pressure steam pipeline 9121 will heat the low-pressure steam by heat conduction to make it become low-pressure and high-temperature steam and enter the steam spray chamber 913. Finally, the low-pressure and high-temperature steam in the steam spray chamber 913 will be sprayed outward through the spray orifice plate 92, thereby heating the flute tip.

[0058] In addition, by designing the diameters of the two low-temperature and low-pressure steam pipes 9111 on both sides to be larger than the diameters of the remaining low-temperature and low-pressure steam pipes 9111, it can be ensured that the low-pressure steam injected from the low-temperature and low-pressure steam inlet 9112 can flow quickly to several low-temperature and low-pressure steam pipes 9111.

[0059] By arranging the diameter of the disc-type high-temperature and high-pressure steam pipe 9121 to be larger on both sides and smaller in the middle, it can be ensured that the high-pressure steam injected from the high-temperature and high-pressure steam inlet 9122 quickly enters the disc-type high-temperature and high-pressure steam pipe 9121 and the high-pressure steam in the disc-type high-temperature and high-pressure steam pipe 9121 is quickly discharged.

[0060] In one specific embodiment, two support seats 93 are further included, and two rotating shafts 100 are rotatably arranged inside the two support seats 93. The same rectangular grooves 931 are opened inside the two support seats 93, and the two ends of the heating plate 91 are inserted into the two rectangular grooves 931 with interference fit. The main function of the two support seats 93 here is to facilitate the connection of the rotating shafts 100 or to fix the components that are auxiliary to the heating plate 91.

[0061] In one of the specific embodiments, a steam exhaust hood 94 is fixed to both sides above the two support seats 93 through a regular L-shaped plate 96, and a blowing pipe 95 blowing upward (air is simultaneously taken in from both ends) is fixed to one side of the two support seats 93 through two mounting blocks 97. A blowing and suction motor 98 is arranged above one of the support frames 20, and the suction port of the blowing and suction motor 98 is connected to the steam exhaust hood 94 (the specific connection method is not shown), and the blowing port 951 of the blowing and suction motor 98 is connected to the blowing pipe 95 (the specific connection method is not shown). During use, the blowing and suction motor 98 will continuously draw air from the steam exhaust hood 94 and blow air into the blowing pipe 95. At this time, the steam diffusing outward is blocked and will not diffuse outward. In addition, the steam sucked away by the steam exhaust hood 94 can be blown out again by the blowing and suction motor 98. Such a cycle makes full use of thermal energy, makes the workplace free of steam corrosion, avoids waste of resources, and reduces the production cost of the enterprise.

[0062] Specifically, a plurality of blowing ports 951 are provided in a straight line on the upper surface of the blowing pipe 95. When the blowing and suction motor 98 blows air toward the blowing pipe 95, the wind will be blown out through the plurality of air ports.
