DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 A steam generator structure in this embodiment includes a casing 1, a water tank 2 is fixed on the right side of the casing 1, a heating device 3 is arranged in the casing 1, the water tank 2 is connected to the heating device 3 through a water inlet structure 4, water resources in the water tank 2 are extracted through the water inlet structure 4 and passed into the heating device 3 for heating to form water vapor, a separation mechanism 5 is also arranged in the casing 1, the water vapor formed in the heating device 3 is passed into the separation mechanism 5, which can play a role of buffering and stabilizing pressure, and the gas is discharged from the top of the separation mechanism 5, and the liquid is pumped into the water tank 2 through the bottom of the separation mechanism 5 for reuse.

[0028] A heating pipe 21 is fixed in the water tank 2 to preheat the water resources in the water tank 2 and improve the heating efficiency of the subsequent heating device 3 .

[0029] The heating device 3 includes a heating tube 301, an insulating layer 302 is fixed to the outside of the heating tube 301, a heating coil 303 is sleeved on the outside of the insulating layer 302, a bottom plate 304 is fixed to the bottom of the heating tube 301, a plurality of support seats 305 evenly distributed along the circumferential direction are fixed to the top of the bottom plate 304 for supporting the heating coil 303, a drainage pipe 306 extending to the bottom of the bottom plate 304 is fixed to the bottom end of the heating tube 301, a drainage valve 307 is fixed to the bottom end of the drainage pipe 306, and after water passes into the heating tube 301, it is heated by the heating coil 303 to generate water vapor.

[0030] As for how water enters the heating cylinder 301, the water inlet structure 4 includes a water inlet pump 401 fixed in the housing 1, and the water inlet of the water inlet pump 401 is fixed through a pipe with one end penetrating and extending into a water inlet pipe 402 in the water tank 2, and the water outlet of the water inlet pump 401 is connected to the bottom of the heating cylinder 301 through a water outlet pipe 403. When water needs to be inlet, the drain valve 307 is in a closed state, and by starting the water inlet pump 401, the water in the water tank 2 is pumped out by the water inlet pipe 402 and sent to the heating cylinder 301 through the water outlet pipe 403, and the water can be passed into the heating cylinder 301 for heating.

[0031] The water vapor in the heating cylinder 301 enters the separation mechanism 5 for gas-liquid separation. Figure 2 As shown, the separation mechanism 5 includes a separation tank 501 fixed to the top of the heating cylinder 301 and connected thereto, a steam exhaust pipe 502 connected thereto is fixed to the top of the separation tank 501, and two return pipes 503 connected thereto are also fixed to the bottom of the separation tank 501, steam is discharged through the steam exhaust pipe 502, and water flows downward from the return pipe 503.

[0032] The recovered water can also be returned to the water tank 2 for reuse. Figure 2 As shown, a water pump 504 and a small water tank 512 are arranged in the housing 1, a connecting pipe 505 is fixed to the water inlet of the water pump 504 through a pipe, two return pipes 503 and the connecting pipe 505 are connected to the small water tank 512, and a return pipe 506 is fixed at one end of the water outlet of the water pump 504 through a pipe and extends to the water tank 2. When the water pump 504 is started, the water flowing into the return pipe 503 returns to the water tank 2 cavity through the connecting pipe 505 and the return pipe 506.

[0033] In order to prevent the water pump 504 from extracting water vapor while pumping water, two groups of control valves 507 are connected to the reflux pipe 503, and a buffer bottle 508 is connected between the two groups of control valves 507. There is an observation glass on the front side of the buffer bottle 508, through which the buffer water level in the buffer bottle 508 can be observed. Before the water pump 504 extracts water in the reflux pipe 503, the bottom control valve 507 is in a closed state and the top control valve 507 is in an open state, and the water in the separation tank 501 can flow into the buffer bottle 508 through the reflux pipe 503. When the water level in the buffer bottle 508 reaches a high level, the top control valve 507 is closed and the bottom control valve 507 is opened, and the water can flow from the buffer bottle 508 into the small water tank 512, and then the water is pumped from the small water tank 512 into the water tank 2, and the steam in the separation tank 501 will not be pumped into the water tank 2.

[0034] Furthermore, since the bottom end of the drain valve 307 is also connected to the connecting pipe 505, when the drain valve 307 is opened, the water with scale can be pumped into the water tank 2 through the connecting pipe 505. Figure 3 As shown, a filter screen 22 is fixed in the water tank 2 to filter scale mixed in the circulating water.

[0035] In addition, a pressure gauge 509 and a safety valve 510 are installed on the top surface of the separation tank 501. When the pressure gauge 509 detects that the pressure in the separation tank 501 is too high, the pressure can be released through the safety valve 510 to improve the safety performance. The top surface of the separation tank 501 is also equipped with a liquid level gauge 511 whose sensing end extends into the heating cylinder 301. The liquid level gauge 511 can be used to determine when to perform the water replenishment operation.

[0036] By adopting the above steam generator structure, water resources can be fully utilized. The specific working method is as follows:

[0037] The heating pipe 21 in the water tank 2 can preheat the water resources. When water needs to be supplied, the drain valve 307 is in a closed state. By starting the water inlet pump 401, the water inlet pipe 402 draws the preheated water in the water tank 2 and sends it to the drain pipe 306 through the water outlet pipe 403. The water can then be passed into the heating cylinder 301. After a suitable amount of water is drawn in, the water inlet pump 401 is turned off, and the heating coil 303 heats the water to generate water vapor. The water vapor enters the separation tank 501, and the steam is discharged through the steam discharge pipe 502. A part of the water that has not been completely evaporated is discharged. The steam condenses into liquid and flows into the buffer bottle 508 through the reflux pipe 503 for storage. When the water level in the buffer bottle 508 is too high, the top control valve 507 is closed and the bottom control valve 507 is opened. The water in the buffer bottle 508 is retained in the small water tank 512, and the water pump 504 is started again. The water returns to the water tank 2 cavity through the connecting pipe 505 and the return pipe 506 for reuse. When the liquid level meter 511 detects that the water level in the heating cylinder 301 is insufficient, the water inlet pump 401 is started again to replenish the water in the heating cylinder 301.

[0038] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
