Description

[0002] The working principle of the heating steam generator is based on the conversion between electrical energy and thermal energy. Its core component is the electric heating element (such as electric heating tube or electric heating wire). When electric current passes through the electric heating element, the electrical energy is converted into thermal energy, which is directly transferred to the water, heating the water and evaporating it into steam. There is a closed heating cavity inside the generator. The water is heated to a boiling state in the cavity, and the generated steam can be transported to where it is needed through pipes.
[0003] At present, the existing steam generating device usually adopts electric heating tubes for heating. However, since the electric heating tubes are arranged closely, the gaps between the electric heating tubes are small, and it is not easy to clean the scale on the surface of the electric heating tubes, which will affect the service life of the electric heating tubes. At the same time, the traditional electric heating tubes are arranged in a horizontal assembly manner, and the assembly parts are sealed with sealing gaskets. The sealing gaskets are prone to aging, which may cause leakage at the fastening joints of the electric heating tubes.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0027] like Figures 1 to 6As shown, the fast energy-saving steam generating device of this embodiment includes a seamless tank body 1, the number of seamless tank bodies 1 is multiple, the seamless tank body 1 is cut and formed by food-grade seamless steel pipe, the tank body structure is formed by multi-section split welding, and adjacent seamless tank bodies 1 are connected by connecting pipes 2. By using the connecting pipes 2, the interiors of multiple seamless tank bodies 1 are kept connected, so as to realize the circulation of steam, and the lower ends of the multiple seamless tank bodies 1 are jointly installed with a connecting box body 3, and a dirt integration area 4 is formed inside the connecting box body 3, and the dirt integration area 4 is used to generate dirt when the water is heated. The impurities are precipitated, and a water inlet pipe 5 is installed at one end of the connecting box body 3. The external water source spreads from the inside of the connecting box body 3 to the inside of the seamless tank body 1 through the water inlet pipe 5. A sewage pipe 6 is installed at the bottom of the connecting box body 3. The sewage pipe 6 is used to discharge the dirt inside the dirt collection area 4. The upper end of the seamless tank body 1 is detachably installed with a mounting plate 7. The mounting plate 7 provides a carrier for the installation of the electric heating tube 8, and the mounting plate 7 can be disassembled later, so that the electric heating tube 8 on the mounting plate 7 can be removed for maintenance. The mounting plate 7 is arranged in a circular array. Several electric heating tubes 8 are arranged in a circular array to ensure the heating effect and ensure that there is a suitable gap between the electric heating tubes 8, which is convenient for cleaning the scale on the surface of the electric heating tubes 8 in the later stage. The electric heating tubes 8 are arranged vertically, and the scale on the electric heating tubes 8 will slide under the action of gravity, which effectively prevents the scale from staying on the electric heating tubes 8 for a long time and reduces the area where the scale stays on the electric heating tubes 8. The lower ends of the electric heating tubes 8 extend to the inside of the seamless tank body 1. When the electric heating tubes 8 are heated, only the scale inside the seamless tank body 1 is heated. Heating is performed. Since the electric heating tube 8 is at a certain height from the dirt collection area 4, the temperature difference between the heating area and the dirt collection area 4 is 18°C. Such a structure will make the dirt collection area 4 less likely to scale. A protective cover 9 is provided on the upper end of the mounting plate 7. The protective cover 9 is used to protect the upper part of the mounting plate 7. A steam generating pipe 10 is installed on the upper end of a connecting pipe 2. The steam generating pipe 10 is used to discharge the generated steam. A water level monitoring component is installed at one end of the connecting box body 3 at the rear of the water inlet pipe 5. The water level monitoring component is used to detect the water level inside the seamless tank body 1.
[0028] Specifically, the bottom end of the dirt collection area 4 is bucket-shaped, and the sewage pipe 6 is installed at the lower end of the connecting box 3, so that the dirt can be completely discharged during the subsequent sewage treatment. An electronic magnesium rod 12 is installed on the front end surface of the connecting box 3, and the electronic magnesium rod 12 extends to the inside of the dirt collection area 4. During the heating process, the inner wall of the seamless tank body 1 is easily corroded by chemical substances such as oxygen, chlorine and minerals dissolved in the water, resulting in corrosion problems. The magnesium rod acts as a "sacrificial anode" and its metallic properties are more active than iron. It can preferentially react with corrosive substances in the water, thereby protecting the seamless tank body 1 from corrosion and effectively extending the service life of the seamless tank body 1.
[0029] Furthermore, a water inlet solenoid valve 13 is installed on the water inlet pipe 5, and a water outlet solenoid valve 14 is installed on the sewage pipe 6. By opening the water inlet solenoid valve 13 and the water outlet solenoid valve 14 at the same time, an automatic sewage discharge structure can be realized, which is convenient for flushing the dirt inside the dirt collection area 4.
[0030] Furthermore, the water level monitoring component includes a connecting pipe 1101, a detection box 1102, a high water level detector 1103, a low water level detector 1104 and a return pipe 1105. The connecting pipe 1101 is installed at one end of the connecting box 3 at the rear of the water inlet pipe 5. The connecting pipe 1101 is L-shaped, and the detection box 1102 is installed at the upper end of the connecting pipe 1101. The high water level detector 1103 is installed at the upper end of the detection box 1102. The low water level detector 1104 is installed at the upper end of the detection box 1102 behind the high water level detector 1103. The high water level detector 1103 and the low water level detector 1104 detect Both ends extend into the interior of the detection box 1102. A return pipe 1105 is installed at the front end of the detection box 1102. One end of the return pipe 1105 is connected to the seamless tank body 1. The water inside the seamless tank body 1 enters the detection box 1102 through the connecting pipe 1101. Based on the principle of communicating vessels, the water level inside the detection box 1102 is the same as the water level inside the seamless tank body 1. The high water level detector 1103 and the low water level detector 1104 will send a signal when the water level reaches the highest or lowest water level, so that the water inside the seamless tank body 1 is always at a suitable water level. The return pipe 1105 is a universal threaded pipe.
[0031] Furthermore, a connecting plate 15 is installed at the upper end of the seamless tank body 1, and the diameter of the connecting plate 15 is larger than that of the seamless tank body 1. The size of the mounting plate 7 is the same as that of the connecting plate 15. A connecting ring 16 is installed on the surfaces of the mounting plate 7 and the connecting plate 15. A connecting assembly is installed at both ends of the connecting ring 16. A contact groove 18 is arranged on the inner surface of the connecting ring 16, and the contact groove 18 is concave. The mounting plate 7 and the connecting plate 15 are both located inside the contact groove 18. By placing the mounting plate 7 on the connecting plate 15, overlapping the connecting plate 15 and the mounting plate 7, and sleeved the connecting ring 16 on the outside of the connecting plate 15 and the mounting plate 7, the connecting assembly is used to combine and fix the connecting plate 15 and the mounting plate 7 to achieve flange assembly. The flange assembly has better sealing and is more convenient for maintenance.
[0032] Furthermore, the connecting assembly includes a connecting block 1701, a connecting rod 1702 and a threaded sleeve 1703. The connecting blocks 1701 are installed at both ends of the connecting ring 16. A connecting groove 19 is installed through one end of the connecting block 1701. A connecting rod 1702 is rotatably connected to the inside of a connecting groove 19 through a rotating shaft. A threaded groove is arranged at one end of the connecting rod 1702. A threaded sleeve 1703 is threadedly connected to the surface of the threaded groove. The diameter of the threaded sleeve 1703 is greater than the height of the connecting groove 19. By rotating the connecting rod 1702, the connecting rod 1702 is located inside the two connecting grooves 19, and then the threaded sleeve 1703 is installed on the threaded groove surface on the connecting rod 1702 to rotate the threaded sleeve 1703. Under the action of the threaded sleeve 1703, the two ends of the connecting ring 16 are brought closer, and under the action of the contact groove 18, the flange connection of the connecting plate 15 and the mounting plate 7 is realized.
[0033] Furthermore, a temperature probe 20 is installed on the upper end of the mounting plate 7 on one side of the electric heating tube 8. The temperature probe 20 is used to detect the temperature inside the seamless tank body 1. An anti-dry-burning electric heating tube probe 21 is installed on the mounting plate 7 on one side of the temperature probe 20. The anti-dry-burning electric heating tube probe 21 works by using the thermocouple effect. The thermocouple is composed of conductors or semiconductors of two different materials. When there is a temperature difference between the two, an electromotive force will be generated, thereby forming an electric current. This effect is called the Seebeck effect. When the surface temperature of the electric heating tube is too high, the probe will detect this change and send a signal, triggering a protection mechanism, thereby controlling the electric heating tube 8 to stop working and playing a protective role.
[0034] Furthermore, a steam secondary heating pipe 22 is provided on the lower surface of the connecting pipe 2 below the steam generating pipe 10, and one end of the steam secondary heating pipe 22 extends into the interior of the steam generating pipe 10. The steam secondary heating pipe 22 effectively increases the steam temperature and reduces the water content of the steam, thereby improving the efficiency of steaming food and achieving a rapid energy-saving effect.
[0035] The method of using this embodiment is as follows: during assembly, the mounting plate 7 is placed on the connecting plate 15, and the connecting plate 15 and the mounting plate 7 are overlapped, and the connecting ring 16 is sleeved on the outside of the connecting plate 15 and the mounting plate 7, so that the connecting rod 1702 is located inside the two connecting grooves 19, and then the threaded sleeve 1703 is installed on the threaded groove surface of the connecting rod 1702, and the threaded sleeve 1703 is rotated. Under the action of the threaded sleeve 1703, the two ends of the connecting ring 16 are brought close to each other, and under the action of the contact groove 18, the flange sealing connection of the connecting plate 15 and the mounting plate 7 is realized. When in use, the external water source is passed through the inlet. The water pipe 5 enters into the dirt collection area 4 and extends into the seamless tank body 1. The electric heating pipe 8 heats the water inside the seamless tank body 1. Since the electric heating pipe 8 and the dirt collection area 4 are at a certain distance, the electric heating pipe 8 and the inside of the dirt collection area 4 have a certain temperature, thereby effectively avoiding scaling in the dirt collection area 4. When the electric heating pipe 8 is heated, the water evaporates to generate water vapor, and the water vapor is discharged through the steam generating pipe 10. In this process, the steam secondary heating pipe 22 performs secondary heating on the water vapor, thereby increasing the steam temperature, reducing the water content of the steam, improving the efficiency of steaming food, and realizing the generation of steam.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
