Description

Technical Field

[0001] The invention belongs to the technical field of micro boiler facilities, and in particular relates to a steam-water dual-purpose boiler. Background Art

[0002] Hot water and / or steam are commonly used in places such as clothing ironing, fabric dyeing and shaping, adhesive application, food production, biopharmaceutical production, tableware disinfection, sauna bathing, winter heating, and vehicle washing, etc. For example, water is usually not allowed to be used for cleaning the interior of a vehicle, and steam should be used for cleaning. Therefore, a micro steam-water dual-purpose boiler with good mobility will undoubtedly be favored by the car washing industry.

[0003] Technical information on dual-purpose steam-water boilers can be found in the public Chinese patent documents, such as the "a new dual-purpose steam-water boiler device" recommended by CN208253547U. Although this patent can achieve the technical effects summarized in paragraph 0009 of its specification, it has the following shortcomings: First, since this patent has not broken away from the constraints of the structural design concept of the fuel boiler, it will inevitably lead to a large volume and cannot be moved as needed; second, since the steam-water separation needs to be achieved through a relatively complex steam collecting and separating tank, not only is the manufacturing cost high, but it also loses the cheap advantage in use, and ultimately leads to a narrow application range. For example, it cannot be applied to the current large-scale car wash sites; third, since it requires both The use of a pot body connected to the furnace body requires the connection of the relatively complex gas collection and separation tank to the pot body, so the volume must be larger than 30L. The use of boilers larger than 30L requires a pressure vessel manufacturing license and a use license, which also limits its application field. Fourthly, because steam and water are led out from different interfaces, such as the upper steam outlet interface (called "steam outlet" in the patent) and the lower hot water outlet interface (called "water outlet" in the patent), and because the first steam-water separation plate, the second steam-water separation plate, the underwater orifice plate and the isolation plate need to be set in the gas collection and separation tank, the complexity of the entire equipment is further increased, and it is almost impossible to perform maintenance during daily use. In view of the above factors, it is necessary to make improvements, and the technical solution to be introduced below is produced in this context. Summary of the invention

[0032] In the present embodiment, the upper insulating sheath 522 and the lower insulating sheath 523 are ceramic sheaths; an external heating tank flange 513 is formed on the outer wall of the bottom of the external heating tank 51 and around the external heating tank 51, and external heating tank flange screw holes 5131 are spaced apart on the external heating tank flange 513, and the external heating tank flange 513 is fixed to the furnace body flange 45c at the bottom of the boiler furnace body 4 by the external heating tank flange fixing screws and after adding the external heating tank flange sealing ring; the electric heating wire spiral circle gap 5241 is formed by the gaps of two adjacent spiral circles above and below the aforementioned electric heating wire 524 spirally wrapped around the outside of the aforementioned water heating vaporization tube 521, and the electric heating wire spiral circle gap 5241 is filled with high-temperature resistant insulating ceramic filler.

[0033] In this embodiment, the number of water-heating vaporization tubes 521 of the structural system of the electric heating steam generating mechanism 5 is three, and the corresponding electric heating wires 524 and power connection devices 525 are also three, which are assembled in the external heating tank cavity 512 of the external heating tank 51. Since the three power connection devices 525 are all electrically connected to the aforementioned electrical controller 7, if they are all enabled as needed, the operator presses the aforementioned full-power switch 742, and if only two of the three are enabled, the half-power switch 743 is pressed. Since the aforementioned steam pressure controller 4711 is electrically connected to the electrical controller 7, the steam pressure in the furnace cavity 43 can be displayed by the aforementioned pressure display gauge 73.

[0034] The user presses the full-power switch 742 or the half-power switch 743. Taking the pressing of the full-power switch 742 as an example, the electric heating wires 524 wrapped around the three water heating vaporization tubes 521 are energized and operated, and the water flowing through the water heating vaporization tubes 521 is heated and vaporized by the electric heating wires 524 through the aforementioned insulating thermal conductive coating 5212. The water in the water heating vaporization tubes 521 is supplied to the water inlet joint 53112 of the water inlet manifold by the aforementioned electric heating water supply pipe 3331, and enters the water inlet manifold cavity 5311, and then enters the water heating vaporization tubes 521 from the water inlet manifold cavity 5311 through the water inlet manifold cover water through hole 5321. At the same time, the water heating vaporization tube 521 heats the external heating tank 51 by means of thermal radiation, and the steam from the water heating vaporization tube 521 is led to the furnace body cavity 43 from the hot water steam outlet 5211, so that the water in the furnace body cavity 43 is heated and steam is generated. At the same time, the water in the furnace body cavity 43 is heated and vaporized by the external heating tank 51.

As needed, a device such as a pump can be provided on the hot water outlet pipeline connected to the upper end of the hot water outlet pipe 41; when steam is to be used, the hot water outlet control valve 411 is closed and the steam outlet control valve 421 is opened. At this time, the upper end of the hot water outlet pipe 41, i.e., the area or pipe section located above the hot water outlet control valve 411, becomes the steam outlet pipe section.

[0036] In the above process, the water pump motor 31 of the diversion water supply mechanism 3 is in working state, and the water pump 32 is driven by the water pump motor shaft 311. The water in the water tank 2 enters the furnace body cavity 43 in sequence through the water tank outlet pipe 231, the water pump water inlet 321, the water pump water outlet 322, the check valve 3222, the water pump outlet pipeline 3221, the three-way joint first interface 331 of the three-way joint 33, the three-way joint second interface 332, the furnace body cavity water inlet pipe 3321 and the furnace body cavity water inlet interface 44. At the same time, it enters the water heating vaporization tube 521 through the three-way joint third interface 333 of the three-way joint 33 through the electric heating water supply pipe 3331 according to the process described above by the applicant.

[0037] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
