[0018] Embodiment 1

[0019] As Figure 1 , Figure 2 The novel steam heater in the example includes a cylinder body 1, a heating pipe 5, a cylinder head one 2, a cylinder head two 3 and an even gas ring 7, the cylinder body 1 is a common cylindrical shape, the fixed plate 4 is arranged at both ends of the cylinder body 1, for example, bolted, the fixed plate 4 seals the end cylinder port of the cylinder body, the cylinder head one 2 and the cylinder head two 3 are connected with the fixed plate 4 at the end of the corresponding cylinder body 1 through bolts.

[0020] A plurality of heating pipes 5 are installed in the barrel 1, and the two ends of the heating pipes 5 are connected with the fixed plates 4 at the corresponding end portions of the barrel 1, respectively. The left end portions of the heating pipes 5 extend into the chamber of the barrel head one 2 and are communicated. The chamber of the barrel head two 3 is divided into an upper portion 31 and a lower portion 32 by a partition plate. The feeding port 33 is installed at the top wall of the chamber of the upper portion 31, and the discharging port 34 is installed at the bottom wall of the chamber of the lower portion 32. The end portions of some of the heating pipes 5 extend into the chamber of the upper portion 31 and are communicated, and the end portions of some of the heating pipes 5 extend into the chamber of the lower portion 32 and are communicated. In use, the material input from the feeding port 33 into the chamber of the upper portion 31 flows into the barrel head one through the heating pipes, and then flows into the heating pipes communicated with the barrel head one, and then is transported into the chamber of the lower portion of the barrel head two, and then is discharged through the discharging port.

[0021] In this example, the air inlet 6 is installed at the barrel 1 adjacent to the barrel head one 2. The air inlet 6 is connected with the inlet 75 of the uniform gas ring 7 installed in the barrel 1. In use, the steam input from the air inlet flows into the uniform gas ring, and then flows into the barrel chamber through the air outlet holes of the uniform gas ring. The heating pipes pass through the ring mouth of the uniform gas ring, which can better heat the heating pipes.

[0022] In this example, the uniform gas ring 7 is of an upper and lower split type, such as the upper half ring 71 and the lower half ring 72 embedded and fixed type. The two end ring mouth end faces of the upper half ring are formed with embedded grooves, and the two ring mouth end faces of the lower half ring are formed with protrusions. The protrusions are embedded in the embedded grooves to make the upper half ring and the lower half ring embedded and fixed as a whole. The inner ring walls of the upper half ring 71 and the lower half ring 72 are formed with a plurality of air outlet holes 74. The air inlet 6 is opposite to the inlet 75 of the upper half ring 71.

[0023] A semicircular notch is formed at the corresponding peripheral wall of the barrel 1 below the air inlet 6. The notch is sealed with the cover plate 8. The size of the notch can allow the upper half ring and the lower half ring to enter and exit.

[0024] The left and right side faces of the upper half ring 71 of the uniform gas ring 7 are partially outwardly protruding. The inner wall of the barrel 1 is formed with a sliding groove 10, such as a semicircular sliding groove 10 extending along the circumference of the barrel 1. The groove opening is horizontally oriented. The outwardly protruding portions 73 of the left and right side faces of the upper half ring 71 are inserted into the groove opening and are slidingly fitted on the circumference of the barrel 1. The upper half ring can be slid to gradually disengage from the end portion of the sliding groove. The sliding groove limits the disengagement of the upper half ring from the barrel, which improves the stability.

[0025] The bottom surface of the cover plate 8 is outwardly protrudingly formed with a support block 81, such as a semicircular support block 81. When the cover plate 8 is fixed in the notch, the support block abuts against the lower half ring to form a support, which helps to improve the stability of the uniform gas ring in the barrel.

[0026] To facilitate the butt joint of the cover plate and the notch, the inlet of the notch is outwardly protruding from the barrel. The bottom surface of the cover plate 8 is grooved, and the outwardly protruding ring ridge of the inlet of the notch is in the groove cavity of the bottom surface of the cover plate 8. The ring ridge can be screwed into the threaded hole on the ring ridge through the bolt from the cover plate.

[0027] In addition, the drain 9 can be formed on the side of the barrel of the cover plate 8 to drain the condensed water.

[0028] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
