[0024] Please refer to Figure 1 - Figure 3 , wherein Figure 1 It is a structure diagram of a steam distribution cylinder in an embodiment of the utility model, the steam distribution cylinder comprises a distribution assembly 1 and a heating rod 2, the distribution assembly 1 comprises an air inlet pipe 11, a distribution pipe 12, a plurality of air outlet pipes 13 and a drain pipe 14, the distribution pipe 12 is horizontally arranged, the air inlet pipe 11 and the air outlet pipe 13 are located above the distribution pipe 12 and are communicated with the distribution pipe 12, the drain pipe 14 is located below the air outlet pipe 13 and is communicated with the distribution pipe 12, one end of the heating rod 2 penetrates the drain pipe 14 and extends into the drain pipe 14, and the other end of the heating rod 2 is connected with an external power supply.

[0025] In the embodiment, the heating structure is formed by the arrangement of the heating rod 2, and the heating rod 2 is installed in the drain pipe 14, so that the staff can be installed or overhauled conveniently, and at the same time, all the condensed water generated by all the steam can be heated twice when passing through the drain pipe 14, so that part of the condensed water can be evaporated twice, the steam evaporated twice can be used twice in the distribution pipe 12, the loss caused by the condensed water is compensated, and the steam effect is effectively improved.

[0026] Further, the end of the heating rod 2 extending into the drain pipe 14 is annular and suspended in the drain pipe 14.

[0027] In one of the embodiments, the outer surfaces of the air inlet pipe 11, the distribution pipe 12, each air outlet pipe 13 and each drain pipe 14 are wrapped with heat preservation cotton 15, polyurethane foam 16 and sheath 17 in sequence.

[0028] In this embodiment, the thermal insulation cotton 15 and the polyurethane foam 16 are both flame-retardant materials, which are used to improve the heat preservation of the pipeline and reduce the loss of steam heat; the sheath 17 is made of stainless steel, which is used to protect the thermal insulation material and prolong the service life.

[0029] In one of the embodiments, the side wall of the drain pipe 14 is provided with a through hole 141, and the heating rod 2 is sleeved in the through hole 141.

[0030] In this embodiment, one end of the heating rod 2 is arranged in the drain pipe 14, and the other end of the heating rod 2 is fixed with a fixed disc after penetrating the through hole 141. The fixed disc is located outside the drain pipe 14, is coaxially arranged with the through hole 141, and is sealingly screwed on the outside of the drain pipe 14. The side of the fixed disc away from the drain pipe 14 is connected with a power supply for power supply of the heating rod 2. The heating principle of the heating rod is the prior art, and therefore will not be described in detail.

[0031] In one of the embodiments, a rubber sealing block 142 is filled between the heating rod 2 and the through hole 141.

[0032] In this embodiment, the main function of the rubber sealing block 142 is to avoid leakage, and the part where the heating rod 2 and the fixed disc are connected is also sleeved with a rubber sealing block 142, which effectively improves the sealing performance of the connection part.

[0033] In one of the embodiments, the air inlet pipe 11 is provided with an air inlet valve 111.

[0034] In this embodiment, the air inlet valve 111 is used to control the opening and closing of the air inlet valve 111 and the flow rate of the steam.

[0035] In one of the embodiments, each air outlet pipe 13 is provided with an air outlet valve 131.

[0036] In this embodiment, the air outlet valve 131 is used to control the opening and closing of the air outlet pipe 13 and the flow rate of the steam. Each air outlet pipe 13 and each air outlet valve 131 do not interfere with each other and can independently operate, which is convenient for the staff to open the corresponding air outlet valve 131 according to the work requirements.

[0037] In one of the embodiments, the inner wall of the drain pipe 14 is provided with a threaded groove 143.

[0038] In this embodiment, the threaded groove 143 is used to slow down the flow rate of the condensed water. Because the flow rate of the condensed water is not high, the condensed water will flow along the inner wall of the pipeline. Through the arrangement of the threaded groove 143, the flow path of the condensed water is increased, and thus the heating time of the condensed water by the heating rod 2 is increased, so that more condensed water is evaporated again. According to the principle that hot gas moves upward, the steam formed by the secondary evaporation will compensate for the steam in the air distribution pipe 12, thereby improving the steam effect.

[0039] In one embodiment, the drain pipe 14 is provided with a drain valve 144, and the drain valve 144 is located below the threaded groove 143.

[0040] In this embodiment, the drain valve 144 controls the opening and closing of the drain pipe 14 and the flow rate of the condensed water. The drain valve 144 is located below the threaded groove 143 to avoid blocking the steam obtained by secondary evaporation by the drain valve 144, so that the steam obtained by secondary evaporation can flow more smoothly into the gas distribution pipe 12.

[0041] Furthermore, the drain valve 144 can also be installed above the heating rod 2. When the heating rod 2 needs to be overhauled, the drain valve 144 can be closed, which does not affect the normal operation of the air inlet pipe 11, the gas distribution pipe 12 and each gas outlet pipe 13. If the overhaul time is relatively long, the drain valve 144 can be opened regularly to clean the condensed water in the lower gas distribution pipe 12. If the overhaul time is relatively short, the drain valve 144 can be opened after the overhaul to restore the use of the drain pipe 14.

[0042] In one embodiment, the bottom end of the gas distribution pipe 12 is fixedly connected with a support frame 18.

[0043] In this embodiment, the support frame 18 supports the gas distribution pipe 12 to a certain height, facilitates the installation of the drain pipe 14, and makes the condensed water flow downward and be discharged from the drain pipe 14.

[0044] In one embodiment, the top end of the support frame 18 is arc-shaped and matched with the outer wall of the gas distribution pipe 12.

[0045] In this embodiment, the outermost layer of the gas distribution pipe 12 is wrapped with a sheath 17, and the top end of the support frame 18 is matched with the shape of the sheath 17, so as to increase the contact area between the support frame 18 and the sheath 17 and improve the stability of the support.

[0046] In order to better understand the present application, the following will be described in detail in combination with Figures 1 to 3 The technical scheme of the present application will be described in detail as follows:

[0047] First, open the inlet valve 111, outlet valve 131 and drain valve 144, heating rod 2 power heating to the preset temperature; then, steam from the inlet pipe 11 into the gas pipe 12, then from the gas pipe 12 into each outlet pipe 13, in the process, the condensed water generated will along with the gas pipe 12 into the drain pipe 14; finally, the condensed water along with the thread groove 143 down the flow of heating rod 2, under the action of heating rod 2, part of the condensed water will be secondary evaporation, secondary evaporation of steam, using the principle of hot gas upward movement, into the gas pipe 12 after the secondary use, and the remaining condensed water is not secondary evaporation with drain pipe 14 back to the boiler to get secondary use, the process effectively compensates for the loss caused by the steam in the gas pipe 12 into condensed water, effectively improve the steam effect.

[0048] The specific embodiments of the present application above do not constitute a limitation on the scope of protection of the present application, and any various other corresponding changes and modifications made according to the technical concept of the present application shall be included in the scope of protection of the claims of the present application.
