Description

Technical Field

[0001] This application relates to the field of boiler technology, and in particular to an energy-saving boiler. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of heat.

[0003] Currently, existing boilers mainly heat the top of the boiler body without effectively utilizing the steam inside the boiler body, resulting in significant waste of thermal energy. Furthermore, when adding water, water is introduced from outside the boiler and then heated to the specified temperature, leading to low heating efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide an energy-saving boiler that can improve thermal energy utilization and heating efficiency to overcome the defects mentioned in the background art.

[0005] An energy-saving boiler includes: An outer pot, one end of which is equipped with a heating device; An inner pot, located at the other end inside the outer pot, has an overflow hole on one side of its top; and A liquid inlet pipe, one end of which passes through the outer pot and extends to the bottom of the inner pot.

[0006] As a preferred embodiment of the energy-saving boiler in this utility model, the top of the outer pot is also provided with a steam outlet and a gas valve.

[0007] As a preferred embodiment of the energy-saving boiler in this utility model, the steam outlet and the steam valve are located above the inner pot.

[0008] As a preferred embodiment of the energy-saving boiler in this utility model, a connecting pipe is provided on one side of the outer pot, and liquid level sensors are provided at intervals inside the connecting pipe.

[0009] As a preferred embodiment of the energy-saving boiler in this utility model, the liquid level sensor includes at least two, and the volume of the outer pot corresponding to the two liquid level sensors that are furthest apart is not greater than the volume of the inner pot.

[0010] As a preferred embodiment of the energy-saving boiler in this utility model, one end of the liquid inlet pipe abuts against the bottom of the inner pot, and a liquid outlet is provided on one side.

[0011] The beneficial effects of this utility model are: This invention integrates the inner pot and the outer pot into one unit. The outer pot is the heating element, and the inner pot is the pre-storage device. When the liquid in the outer pot decreases, the liquid inlet pipe replenishes the liquid to the bottom of the inner pot. The liquid in the upper part of the inner pot is automatically added to the outer pot. Since the inner pot is inside the outer pot, the liquid temperature in the inner pot has already reached the boiling point. The outer pot does not need to heat the added liquid from a low temperature to boiling. This effectively utilizes heat energy and improves the overall heating efficiency. Attached Figure Description

[0020] Example This embodiment provides an energy-saving boiler, such as Figure 1 and Figure 2 As shown, the device includes an outer pot 1000, an inner pot 2000, and a liquid inlet pipe 3000. The inner pot 2000 is located at the top inside the outer pot 1000. The liquid inlet pipe 3000 passes through the top of the outer pot 1000 and extends to the bottom of the inner pot 2000. The inner pot 2000 is pre-stored with liquid. When the outer pot 1000 needs to be replenished with liquid, the external liquid flows into the inner pot 2000 through the liquid inlet pipe 3000, and the liquid in the upper part of the inner pot 2000 flows into the outer pot 1000.

[0021] The aforementioned boiler integrates the outer pot 1000 and the inner pot 2000 into one unit. The outer pot 1000 is the heating element, and the inner pot 2000 is the pre-storage liquid device. When the liquid in the outer pot 1000 decreases, the liquid inlet pipe replenishes the liquid to the bottom of the inner pot, and the water in the upper part of the inner pot is automatically added to the outer pot. Since the inner pot is inside the outer pot, the liquid temperature in the inner pot has already reached the boiling point, and the outer pot does not need to heat the added liquid from a low temperature to boiling. This effectively utilizes thermal energy and improves the overall heating efficiency.

[0022] The outer pot 1000 is also provided with a steam outlet 4000 and a valve 5000 on its top, and the steam outlet 4000 and the valve 5000 are located above the inner pot 2000.

[0023] The steam outlet 4000 and the valve 5000 are used to control the discharge of steam inside the outer pot 1000. The parts of the steam outlet 4000 and the valve 5000 that extend into the outer pot 1000 are not directly connected, but are indirectly connected to the outer pot 1000 by extending into the inner pot 2000. When the liquid in the outer pot 1000 boils, the solid particles splashed up will not directly hit the steam outlet 4000, thereby reducing the formation of scale at the steam outlet 4000 and reducing the chance of blockage.

[0024] The outer pot 1000 can be divided into a heating zone and a steam zone, with the bottom of the inner pot 2000 serving as the boundary between them. A detection device for detecting the internal liquid level is provided on one side of the outer pot 1000, which includes a connecting pipe 6000. One end of the connecting pipe 6000 is located in the heating zone, and the other end is located in the steam zone. Liquid level sensors 7000 are spaced apart inside the connecting pipe 6000.

[0025] The liquid level sensor 7000 includes at least two. The height of the uppermost liquid level sensor 7000 does not exceed the height of the bottom of the inner pot 2000. The volume of the outer pot 1000 corresponding to the two liquid level sensors 7000 that are furthest apart does not exceed the volume of the inner pot 2000, and is preferably half the volume of the inner pot 2000. This ensures that after the liquid in the inner pot 2000 enters the outer pot 1000, the temperature of the liquid inside the outer pot 1000 drops little, and steam generation can be maintained continuously.

[0026] The top of the inner pot 2000 is connected to the top of the interior of the outer pot 1000, and one side of it is connected via a... Figure 3 The overflow hole 2100 shown is connected to the outer pot 1000, and the bottom of the outer pot 1000 is provided with a heating device 1100 for heating the internal liquid.

[0027] One end of the liquid inlet pipe 3000 is connected to an external liquid supply device, and the other end extends through the outer pot 1000 to the bottom of the inner pot 2000 and abuts against it. A liquid outlet 3100 is provided on one side of the pipe.

[0028] When the liquid level in the outer pot 1000 is lower than the lowest liquid level sensor 7000, the liquid replenishment device replenishes the inner pot 2000 through the liquid inlet pipe 3000. The preheated liquid in the inner pot 2000 flows out of the outer pot 1000. The replenishment stops when the liquid level reaches the set liquid level sensor 7000 or the highest liquid level sensor 7000.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
