Description

Technical Field

[0001] The utility model relates to the technical field of steam generators, in particular to an electric heating steam generating device with a protective device. Background Art

[0002] A steam generator is a device that generates water vapor by vaporizing water through heat. Steam generators are more common in the fields of heating and power generation. Common steam generators usually use electric heating, coal heating, gas heating, and waste heat heating.

[0003] Existing electric heating steam generating devices will generate a large amount of water vapor when working. Due to pipeline flow restrictions, high temperature inside the device resulting in more steam generation, etc., it is easy to cause the air pressure inside the device to increase. In order to prevent the device from being cracked by the air pressure of the water vapor, various pressure relief structures are usually set up to discharge excess water vapor, but direct discharge to the outside is likely to cause waste. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an electrically heated steam generating device with a protective device to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an electric heating steam generating device with a protective device, comprising a device main body, a shell connected to the top of the device main body, and a connecting hole is opened at the lower part of the shell, a sealing plate is connected to the inside of the shell, an adjusting screw passes through one side of the bottom of the shell, and a pressure plate is connected to one side of the adjusting screw, a spring is connected between the sealing plate and the pressure plate, a pressure relief pipe is connected to the top of the shell, an outer shell is connected on both sides of the top of the device main body, and a second insulation shell is connected to the inside of the outer shell.

[0006] By adopting the above technical solution, when the air pressure in the device is too high, water vapor will push up the sealing plate and be discharged through the connecting hole and the pressure relief pipe. While circulating, the water vapor transfers heat to the second insulation shell through the copper pressure relief pipe, thereby preheating the water in the second insulation shell and reducing heat waste. The pressure relief pipe is serpentine to extend the residence time of water vapor in the second insulation shell and increase the contact area with water. The position of the pressure plate is adjusted by rotating the adjusting screw to force the spring to contract, thereby changing the air pressure required for the water vapor to push open the sealing plate during pressure relief.

[0007] Furthermore, the sealing plate is slidably connected to the connecting hole.

[0008] By adopting the above technical solution, when the air pressure in the device is too high, water vapor will lift up the sealing plate and be discharged through the connecting hole and the pressure relief pipe, thereby reducing the pressure in the main body of the device.

[0009] Furthermore, the pressing plate is slidably connected to the shell.

[0010] By adopting the above technical solution, when the air pressure in the device is too high, water vapor will push up the sealing plate and be discharged through the connecting hole and the pressure relief pipe, and the position of the pressure plate can be adjusted by rotating the adjusting screw, thereby changing the air pressure required for water vapor to push open the sealing plate during pressure relief.

[0011] Furthermore, the pressing plate is threadedly connected to the adjusting screw, and the adjusting screw is rotationally connected to the shell.

[0012] By adopting the above technical solution, the staff can adjust the position of the pressure plate by rotating the adjusting screw to make the spring contract under force, thereby changing the air pressure required for the water vapor to push open the sealing plate during pressure relief.

[0013] Furthermore, the pressure relief pipe is serpentine-shaped and is made of copper material.

[0014] By adopting the above technical solution, water vapor transfers heat to the second insulation shell through the copper pressure relief pipe while circulating, and the serpentine shape of the pressure relief pipe prolongs the residence time of water vapor in the second insulation shell and increases the contact area with water.

[0015] Furthermore, the pressure relief pipe is located inside the second insulation shell.

[0016] By adopting the above technical solution, water vapor transfers heat to the second insulation shell through the copper pressure relief pipe while circulating, thereby preheating the water in the second insulation shell.

[0017] Furthermore, a water inlet is connected to one side of the top of the outer shell, a first heat-insulating shell is connected to the inside of the device body, an electric heating rod is installed inside the first heat-insulating shell, and an air outlet is arranged above the outer surface of the device body.

[0018] By adopting the above technical solution, the staff allows water to pass through the second insulation shell and the solenoid valve into the first insulation shell through the water inlet. At this time, the staff turns on the electric heating rod. After the electric heating rod is started, it generates heat to heat the water. When the water temperature rises to the boiling point, a large amount of water evaporates to produce water vapor, and then the water vapor is discharged through the air outlet.

[0019] Furthermore, a solenoid valve is installed between the shell and the device body.

[0020] By adopting the above technical solution, the staff opens the solenoid valve to allow the water in the second insulation shell to enter the first insulation shell, and the staff closes the solenoid valve after the water is added.

[0021] Furthermore, two electric heating rods are provided, and the two electric heating rods are symmetrically distributed.

[0022] By adopting the above technical solution, the electric heating rod generates heat to heat the water after being started. When the water temperature rises to the boiling point, a large amount of water evaporates to generate water vapor.

[0023] Furthermore, a motor is installed on one side of the bottom of the device body, and a magnetic stirrer is connected to the output end of the motor.

[0024] By adopting the above technical solution, the motor drives the magnetic stirrer to rotate, and the magnetic stirrer stirs the water after rotating, so that the water in the second heat-insulating shell is evenly heated.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] The utility model is provided with a pressure relief pipe, a second insulation shell, a shell, a connecting hole, a sealing plate, a spring, a pressure plate and an adjusting screw. When the air pressure in the device is too high, water vapor will push up the sealing plate and pass through the connecting hole and the pressure relief pipe to be discharged. While circulating, the water vapor transfers heat to the second insulation shell through the copper pressure relief pipe, thereby preheating the water in the second insulation shell and reducing heat waste. The pressure relief pipe is serpentine to extend the residence time of the water vapor in the second insulation shell and increase the contact area with the water. The position of the pressure plate is adjusted by rotating the adjusting screw to force the spring to contract, thereby changing the air pressure required for the water vapor to push up the sealing plate during pressure relief. The water vapor discharged during pressure relief is used for waste heat recovery, thereby reducing waste. BRIEF DESCRIPTION OF THE DRAWINGS

When the air pressure in the device is too high, water vapor will lift the sealing plate 14 and pass through the connecting hole 13 and the pressure relief pipe 6 to be discharged; an adjusting screw 17 is passed through one side of the bottom of the shell 12, and the adjusting screw 17 is rotatably connected to the shell 12. A pressure plate 16 is connected to one side of the adjusting screw 17, and the pressure plate 16 is slidably connected to the shell 12. The pressure plate 16 is threadedly connected to the adjusting screw 17. A spring 15 is connected between the sealing plate 14 and the pressure plate 16. The staff can adjust the position of the pressure plate 16 by rotating the adjusting screw 17 to make the spring 15 stressed. Contraction, thereby changing the air pressure required for the water vapor to push open the sealing plate 14 during pressure relief; a pressure relief pipe 6 is connected to the top of the shell 12, and the pressure relief pipe 6 is serpentine. The pressure relief pipe 6 is made of copper material. While the water vapor is circulating, it transfers heat to the second insulation shell 10 through the copper pressure relief pipe 6, thereby preheating the water in the second insulation shell 10 and reducing heat waste. The pressure relief pipe 6 is serpentine to extend the residence time of the water vapor in the second insulation shell 10 and increase the contact area with the water; the outer shell 4 is connected to both sides of the top of the device body 1, and the second insulation shell 10 is connected to the inside of the outer shell 4. The pressure relief pipe 6 is located inside the second insulation shell 10, and an electromagnetic valve 11 is installed between the outer shell 4 and the device body 1 to temporarily store part of the water for heat recovery.

[0035] See also Figure 1 and Figure 2 In the above embodiment, a water inlet 5 is connected to one side of the top of the shell 4, and water is input into the second insulation shell 10 through the water inlet 5; the first insulation shell 9 is connected to the inside of the device body 1 to reduce heat escape and thus reduce energy consumption; an electric heating rod 3 is installed inside the first insulation shell 9, and two electric heating rods 3 are provided, and the two electric heating rods 3 are symmetrically distributed. An air outlet 2 is provided above the outer surface of the device body 1. After the electric heating rod 3 is started, heat is generated to heat up the water. When the water temperature rises to the boiling point, a large amount of water evaporates to generate water vapor, and then the water vapor is discharged through the air outlet 2. Embodiment 2:

[0036] On the basis of the above-mentioned embodiment 1, although the water vapor discharged during pressure relief can be recovered as waste heat by arranging the pressure relief pipe 6, the second insulation shell 10, the shell 12, the connecting hole 13, the sealing plate 14, the spring 15, the pressure plate 16 and the adjusting screw 17, thereby reducing waste; however, the amount of water in the first insulation shell 9 is large, and it is difficult to heat it evenly, thereby prolonging the heating time; now, by arranging the motor 7 and the agitator, it is possible to stir the water conveniently so that the water is heated evenly.

[0037] See also Figure 1 and Figure 2 In the above embodiment, a motor 7 is installed on one side of the bottom of the device body 1, and an agitator is connected to the output end of the motor 7. The motor 7 drives the agitator to rotate. After the agitator rotates, the water is stirred, so that the water in the second insulation shell 10 is evenly heated. Embodiment three:

[0038] On the basis of the above-mentioned embodiment 2, although the water in the second insulation shell 10 can be evenly heated by arranging the motor 7 and the agitator 8; however, the ordinary agitator needs to penetrate the inner wall of the device body 1, and wear occurs between the rotation of the agitator and the seal, thereby increasing the possibility of water leakage; now, by arranging the motor 7 and the magnetic agitator 8, it is possible to penetrate the device body 1 without moving parts, thereby reducing the occurrence of seal wear and water leakage.

[0039] See also Figure 1 and Figure 2 In the above embodiment, a motor 7 is installed on one side of the bottom of the device body 1, and a magnetic stirrer 8 is connected to the output end of the motor 7. The motor 7 drives the magnetic stirrer 8 to rotate. After the magnetic stirrer 8 rotates, it stirs the water, so that the water in the second insulation shell 10 is evenly heated.

[0040] The implementation principle of the utility model is as follows: first, the staff inputs water into the second insulation shell 10 through the water inlet 5, and at the same time, the staff opens the solenoid valve 11 to allow the water in the second insulation shell 10 to enter the first insulation shell 9. After the water is added, the staff closes the solenoid valve 11, and at this time, the staff turns on the electric heating rod 3, which generates heat to heat the water after it is started. When the water temperature rises to the boiling point, a large amount of water evaporates to generate water vapor, and then the water vapor is discharged through the air outlet 2. At the same time, the motor 7 drives the magnetic stirrer 8 to rotate, and the magnetic stirrer 8 rotates to stir the water, so that the water in the second insulation shell 10 is evenly heated;

[0041] When the air pressure in the device is too high, water vapor will lift the sealing plate 14 and be discharged through the connecting hole 13 and the pressure relief pipe 6. While circulating, the water vapor transfers heat to the second insulation shell 10 through the copper pressure relief pipe 6, thereby preheating the water in the second insulation shell 10 and reducing heat waste. The pressure relief pipe 6 is serpentine to extend the residence time of water vapor in the second insulation shell 10 and increase the contact area with water. The staff can adjust the position of the pressure plate 16 by rotating the adjusting screw 17 to force the spring 15 to contract, thereby changing the air pressure required for the water vapor to push open the sealing plate 14 during pressure relief.

[0042] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
