Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, specifically to an electric heating steam generator. Background Technology

[0002] A steam generator, also called a steam heat source machine (commonly known as a boiler), is a mechanical device that uses the heat energy of electricity or other energy sources to heat water into steam.

[0003] Currently, most common steam generators are electrically heated. These generators consist of a furnace body and an electric heater installed inside the furnace body. In existing technology, the electric heater is usually directly installed inside the furnace body, and multiple heaters typically face the same side, increasing the furnace diameter and making the steam generator's water capacity exceed 30 liters. This results in failure to meet national inspection-exemption requirements. Therefore, there is an urgent need to design an electrically heated steam generator to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide an electric heating steam generator to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An electric heating steam generator includes a furnace body, a support cylinder 1 welded to one outer wall of the furnace body, a support cylinder 2 welded to the outer wall of the furnace body away from the support cylinder 1, an electric heater 1 installed inside the support cylinder 1, an electric heater 2 installed inside the support cylinder 2, an exhaust pipe welded to the top outer wall of the furnace body, and a water inlet pipe welded to the center of the bottom end of the furnace body.

[0006] Furthermore, a support cylinder three is welded to one side of the outer wall of the furnace body, and an electric heater three is installed inside the support cylinder three. The support cylinder three is perpendicular to the support cylinder one, and the support cylinder three and the support cylinder one are distributed at different heights.

[0007] Furthermore, a support cylinder four is welded to one side of the outer wall of the furnace body, and an electric heater four is installed inside the support cylinder four. The support cylinder four is perpendicular to the support cylinder one.

[0008] Furthermore, a level gauge is connected to one side of the outer wall of the furnace body, and a base is fixed to the bottom of the furnace body.

[0009] Furthermore, a pressure gauge and a safety valve are respectively installed on the top outer wall of the furnace body.

[0010] Furthermore, the inner wall of the furnace body is provided with an anti-scaling layer, and the outer wall of the furnace body is provided with a corrosion-resistant layer.

[0011] Furthermore, support cylinder one and support cylinder two are symmetrical, and support cylinder three and support cylinder four are symmetrical.

[0012] In the above technical solution, the electric heating steam generator provided by this utility model has the following advantages: by welding support cylinder 1 and support cylinder 2 to both sides of the furnace body, and installing electric heater 1 and electric heater 2 inside support cylinder 1 and support cylinder 2 respectively, the diameter of the furnace body can be reduced, achieving the effect of the steam generator having a water volume of less than 30 liters, thereby meeting the national inspection exemption requirements; by installing electric heater 3 and electric heater 4 on the side of the furnace body, the effect of four electric heaters working simultaneously is achieved, thereby making the steam generator have a high steam output efficiency. Furthermore, electric heater 1 and electric heater 3 are installed at different heights, ensuring that the installation of electric heater 1, electric heater 2, electric heater 3 and electric heater 4 do not interfere with each other without increasing the diameter of the furnace body.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the following will be described in conjunction with the appendix. Figure 1-5 This utility model will be described in further detail. Example 1

[0021] This utility model provides an electric heating steam generator, such as... Figure 1 and Figure 5 As shown, the furnace includes a furnace body 1 with a circular cross-section. A support cylinder 2 is welded to one outer wall of the furnace body 1, and a second support cylinder 3 is welded to the outer wall of the furnace body 1 away from the first support cylinder 2. Both the second support cylinder 3 and the first support cylinder 2 are connected to the furnace body 1, and their axes are the same. An electric heater 4 is installed inside the first support cylinder 2, and an electric heater 5 is installed inside the second support cylinder 3. Both the second electric heater 5 and the first electric heater 4 are existing electric heating components, preferably model JSD-FBFL. A steam outlet pipe 14 is welded to the top outer wall of the furnace body 1. A water inlet pipe 10 is welded to the center of the bottom of the furnace body 1, through which water to be heated enters the furnace body 1. A level gauge 15, also existing technology, is connected to one outer wall of the furnace body 1 to detect the water level inside the furnace body 1. A solenoid valve is also installed at the water inlet pipe 10 to allow the level gauge 15 to detect the water level. When the water level is too high or too low, it transmits an electrical signal to the host computer, which then controls the solenoid valve to close and open, thereby maintaining the water level inside the furnace body 1 within a certain range. A base 11 is fixed to the bottom of the furnace body 1. A pressure gauge 13 and a safety valve 12 are respectively installed on the top outer wall of the furnace body 1. The safety valve 12 is also existing technology, which can automatically release pressure when the internal pressure of the furnace body 1 is too high. The pressure gauge 13 is used to display the internal pressure of the furnace body 1, and a controller can be installed at the side interface where the pressure gauge 13 is installed. When the pressure sensor of the controller detects that the pressure is too high or too low, the controller can adjust the power of the heater. The specific principle is existing technology. The inner wall of the furnace body 1 is provided with an anti-scaling layer 17, which is a graphite coating, to prevent scale from condensing on the inner wall of the furnace body 1. The outer wall of the furnace body 1 is provided with a corrosion-resistant layer 16, which is a rust-preventive oil, making the outer wall of the furnace body 1 less prone to rust. Example 2

[0022] The basic structure in this embodiment is the same as that in Embodiment 1, such as... Figure 2 As shown, the difference is that a support cylinder 3 6 is welded to one side of the outer wall of the furnace body 1, and an electric heater 3 7 is installed inside the support cylinder 3 6. The support cylinder 3 6 is perpendicular to the support cylinder 1 2, and the support cylinder 3 6 and the support cylinder 1 2 are distributed at different heights. By adding the electric heater 3 7, the steam generation efficiency of the steam generator is improved. Example 3

[0023] The basic structure in this embodiment is the same as that in embodiment 2, such as... Figure 3 and Figure 4 As shown, the difference lies in that a support cylinder 4 8 is welded to one side of the outer wall of the furnace body 1, and an electric heater 4 9 is installed inside the support cylinder 4 8. The support cylinder 4 8 is perpendicular to the support cylinder 1 2. The support cylinder 1 2 and the support cylinder 2 3 are symmetrical, and the support cylinder 3 6 and the support cylinder 4 8 are symmetrical. By installing the electric heater 3 7 and the electric heater 4 9 on the side of the furnace body 1, the effect of four electric heaters working simultaneously is achieved, which makes the steam generator have a high steam output efficiency. Furthermore, the electric heater 1 4 and the electric heater 3 7 are installed at different heights, which ensures that the installation of the electric heater 1 4, the electric heater 2 5, the electric heater 3 7 and the electric heater 4 9 do not interfere with each other without increasing the diameter of the furnace body 1.

[0024] Working principle: When in use, water is introduced into the furnace body 1 through the water inlet pipe 10, and the water is heated simultaneously by electric heater 1 4, electric heater 2 5, electric heater 3 7 and electric heater 4 9, so that the water turns into steam and flows out from the steam outlet pipe 14.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
