Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0042] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0043] In order to solve the technical problem in the prior art that the steam furnace is large in size and needs to occupy more installation space; for this purpose, an embodiment of the utility model provides a superheated steam furnace.

[0044] The following is a detailed description of the specific structure of a superheated steam furnace provided by the present utility model. Figure 1-4 As shown in FIG. 1 , the specific structure of the superheated steam furnace includes an outer shell 1 , a heat pipe 2 , a support frame 3 , a heating coil 4 and a heating controller.

[0045] According to the attached Figure 2 As shown, a receiving cavity 11 is formed in the outer shell 1; specifically, the receiving cavity 11 is used to accommodate the heat pipe 2, the support frame 3, the heating coil 4 and the heating controller, thereby preventing the high temperature generated by the heating coil 4 and the heat pipe 2 from scalding the staff or other objects when heating.

[0046] Part of the heat conducting pipe 2 is disposed in the accommodating cavity 11 , and the inlet end 23 and the outlet end 24 of the heat conducting pipe 2 are respectively connected to the water supply machine and the heated equipment.

[0047] Specifically, water or other liquids are heated in the steam furnace to be converted into steam. The heating source in the furnace (for example, through the heating coil 4) provides sufficient energy to increase the temperature of the water or liquid to above the boiling point, thereby forming steam. Subsequently, the steam flows along the outlet end 24 of the heat pipe 2. The steam is transmitted in the heat pipe 2 due to the pressure difference and the temperature difference, and is finally transmitted to the heated equipment through the outlet end 24.

[0048] It should be noted that, due to the heat conduction property of the tube wall of the heat-conducting tube 2, the heat inside the steel tube can be transferred to the outside, thereby achieving the heat transfer effect of steam.

[0049] It can be understood that the heated equipment in the embodiment of the utility model is a domestic steam boiler, an industrial boiler, a power generation boiler or a marine boiler, etc., without specific limitation; and the heat conduction pipe 2 in the embodiment of the utility model is a steel pipe, an alloy steel pipe, a stainless steel pipe or a copper pipe, without specific limitation.

[0050] The support frame 3 is built into the bottom of the accommodating cavity 11 , and a plurality of support holes 322 for the heat conducting pipes 2 to pass through are formed through the support frame 3 .

[0051] Specifically, when each heat pipe 2 is respectively passed through a plurality of support holes 322 on the support frame 3, the support frame 3 is used to support the entire heat pipe 2, thereby preventing the heat pipe 2 from shaking violently when transferring steam.

[0052] It should be noted that the outer diameters of the multiple support holes 322 on the aforementioned support frame 3 are all compatible with the outer diameters of each heat pipe 2. The hole walls of the support holes 322 are in contact with the outer sides of the heat pipes 2 to fix the heat pipes 2. This arrangement improves the stability of the heat pipes 2.

[0053] The heating coil 4 is wound on the heat-conducting tube 2 located in the accommodating chamber 11. Specifically, the heating coil 4 is wound along the height of the heat-conducting tube 2 located in the accommodating chamber 11, so that the heating effect can be further enhanced. When water flows into the heat-conducting tube 2 located in the accommodating chamber 11, by transferring the current to the heating coil, the heating coil at this time has a resistance loss, and releases a large amount of heat and this part of the heat can be transferred to the side wall of the heat-conducting tube 2. Since the heat-conducting tube 2 has an excellent heat conduction effect, the water flowing into the heat-conducting tube 2 can be quickly heated, so that it is heated to form steam, and finally transferred to the heated equipment.

[0054] It can be understood that the heating coil 4 of the embodiment of the utility model is composed of multiple resistance wires, and the resistance wires are nickel-chromium alloy heating wires or tungsten wires, which are not specifically limited.

[0055] The heating controller includes a control module and a power supply, the power supply is electrically connected to the heating coil 4, and the control module is controlled and connected to the power supply. Specifically, by connecting the power supply to the armature of the heating coil, the power supply provides voltage and current, so when the power supply is powered on, the current can be transmitted to the heating coil.

[0056] In order to ensure the safety and stability of heating, the control module is used to monitor and control the heating process of the heating coil to ensure that the heating temperature is within a safe range.

[0057] In summary, when water flows into the heat pipe 2 located in the accommodating chamber 11, a large amount of heat is released through the heating coil and transferred to the side wall of the heat pipe 2, and the water flowing into the heat pipe 2 is quickly heated to form steam, which is finally transferred to the heated equipment, thereby improving the heating effect of the steam furnace. Compared with the existing large steam furnaces, the superheated steam furnace in the embodiment of the utility model is smaller in size.

[0058] According to the attached Figure 3 As shown, in some specific embodiments, the superheated steam furnace also includes a temperature measuring screw 5, a detection end (temperature sensor) of the temperature measuring screw 5 is passed through the heat pipe 2, and the temperature measuring screw 5 is connected to the control module for signal transmission to detect the temperature inside the heat pipe 2.

[0059] Specifically, a temperature sensor is provided inside the temperature measuring screw 5. The temperature sensor is a thermistor (RTD) or a thermocouple sensor. The thermistor is a device that can change with temperature. When the temperature rises, the resistance value of the thermistor increases; conversely, when the temperature decreases, the resistance value decreases. The temperature sensor of the temperature measuring screw 5 is connected to the control module through signal transmission. The resistance value of the temperature sensor changes with temperature, and then the resistance value is converted into a corresponding temperature value (realized by pre-calibrating and calibrating the resistance-temperature relationship of the sensor). Finally, the measured temperature value is displayed on the display screen of the peripheral device.

[0060] In some specific embodiments, two through-holes are formed on the top surface or the side surface of the outer shell 1 for the inlet end 23 and the outlet end 24 of the heat conducting pipe 2 to pass through respectively.

[0061] Specifically, the two through openings are a first through opening and a second through opening, the inlet end 23 of the heat conducting pipe 2 is penetrated into the accommodating cavity 11 through the first through opening, and the outlet end 24 of the heat conducting pipe 2 is penetrated out of the accommodating cavity 11 through the second through opening.

[0062] In a further embodiment, the outer diameters of the first opening and the second opening are larger than the inlet end 23 and the outlet end 24 of the heat pipe 2. This arrangement facilitates the inlet end 23 and the outlet end 24 of the heat pipe 2 to be respectively provided with the first opening and the second opening.

[0063] In a further embodiment, the first through-hole and the second through-hole are both covered with cover plates, and each cover plate is respectively mounted on the inlet end 23 and the outlet end 24 of the heat pipe 2. Such an arrangement can prevent the inlet end 23 and the outlet end 24 of the heat pipe 2 from shaking at the first through-hole and the second through-hole respectively.

[0064] According to the attached Figure 2-3As shown, in some specific embodiments, the inlet end 23 and the outlet end 24 of the heat pipe 2 are detachably provided with flanges 25. Specifically, the inlet end 23 and the outlet end 24 of the heat pipe 2 are respectively connected to different pipelines through the flanges 25, and at the same time, they can also play a sealing role, thereby ensuring the smooth flow of fluid or steam, thereby helping to maintain the normal operation of the boiler system.

[0065] In order to improve the space utilization of the accommodating chamber 11 and reduce the volume of the entire steam furnace; Figure 3 As shown, in some specific embodiments, the heat pipe 2 includes two sections of tube body that are interconnected; the front section of the tube body is straight, and the rear section of the tube body is curved or angled.

[0066] Specifically, by arranging multiple tubes into straight shapes, curved shapes, or angled shapes, the length of the entire heat pipe 2 can be extended in the limited accommodating cavity 11, and the limited installation space in the accommodating cavity 11 can be effectively utilized to ensure that when water passes through multiple sections of the tube, the heating coil is sufficient to heat the water to form steam. This arrangement can improve the heating effect of the steam furnace and further reduce the volume of the entire steam furnace.

[0067] According to the attached Figure 2-3 As shown, in some specific embodiments, the support frame 3 includes a base 31 and a support plate 32; the base 31 is fixedly disposed at the bottom of the accommodating cavity 11; the support plate 32 is detachably disposed on the top of the base 31; and each support hole 322 is formed on the support plate 32.

[0068] Specifically, the support plate 32 is supported by the base 31 so as to be at a certain distance from the bottom surface of the accommodating cavity 11. With such a configuration, when the heat pipe 2 is passed through each support hole 322, it is at a certain distance from the bottom surface of the accommodating cavity 11, and thus cannot collide with the bottom surface of the accommodating cavity 11.

[0069] It can be understood that the curved or angled tube body of the heat conducting tube 2 is at a certain distance from the bottom surface of the accommodating cavity 11 .

[0070] In order to improve the convenience of the support plate 32 during the disassembly process, so as to facilitate the subsequent disassembly of the heat pipe 2; Figure 4 As shown, in some specific embodiments, a plurality of fixing holes 311 are formed on the top surface of the base 31; a plurality of locking holes 321 corresponding to and connected to the fixing holes 311 are formed on the support plate 32; and a plurality of locking members are respectively and simultaneously inserted into the fixing holes 311 and the locking holes 321 to fix the support plate 32.

[0071] Specifically, when assembling the support plate 32, it is only necessary to connect the fixing hole 311 on the base 31 with the locking hole 321 on the support plate 32 accordingly, and then insert the locking piece into the locking hole 321 and the fixing hole 311 at the same time to fix the support plate 32 on the top of the base 31; conversely, when disassembling the support plate 32, it is only necessary to detach the locking piece from the fixing hole 311 and the locking hole 321, and then the support plate 32 can be taken out from the top of the base 31.

[0072] In some optional embodiments, the aforementioned locking member is a bolt, a screw or a screw, etc., which is not specifically limited.

[0073] In a further embodiment, each locking hole 321 is a waist-shaped hole. With this arrangement, the position of the support plate 32 can be adjusted within the length range of the waist-shaped hole. Subsequently, the support plate 32 can be fixed in the current position by only inserting the locking piece into the waist-shaped hole and the fixing hole 311 at the same time, thereby improving the flexibility of the support plate 32 during assembly.

[0074] According to the attached Figure 1 As shown, in some specific embodiments, the top surface, bottom surface and side surface of the outer shell 1 are penetrated with a plurality of heat dissipation holes 12. Since a large amount of heat is generated inside the outer shell 1 when the heating coil is heated, a plurality of heat dissipation holes 12 can provide ventilation channels, so that the heat inside the outer shell 1 can be quickly dissipated to the outside, thereby avoiding overheating inside the outer shell 1 and ensuring the stability of the working environment of the steam furnace.

[0075] In some specific embodiments, an opening communicating with the accommodating cavity 11 is formed through the side surface of the outer shell 1 , and a side plate 13 for opening or closing the opening is disposed in the opening.

[0076] Specifically, if maintenance is required on the components in the outer shell 1 , the side plate 13 is opened to open the opening, and then the relevant maintenance work can be performed on the components in the outer shell 1 , and then the opening can be closed through the side plate 13 .

[0077] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
