Description

Technical Field

[0001] The utility model relates to a dry - burning prevention protection device for an electric steam boiler, belonging to the technical field of electric steam boilers. Background Technique

[0002] As a device that converts electrical energy into heat energy and then heats water to generate steam, the electric steam boiler plays an important role in modern industry and life. To ensure its safe operation, preventing the occurrence of dry - burning is crucial.

[0003] Chinese published patent (Publication No.: CN 218864144 U) discloses an electric steam boiler, including an electric steam boiler body and a purification box. An electric heating plate is installed at the bottom inside the electric steam boiler body. A first water level sensor is installed at the bottom of one end inside the electric steam boiler body, and a second water level sensor is installed at the top near the first water level sensor inside the electric steam boiler body. A first water pump is installed at the top of the electric steam boiler body near the first water level sensor. The utility model is equipped with a water suction pipe, a second water pump, a connecting pipe, and a heating pipe. During use, the second water pump pumps out the liquid inside the electric steam boiler body, and then the liquid flows back into the electric steam boiler body through the heating pipe, enabling the liquid inside the electric steam boiler body to circulate, so that all the liquid can be in full contact with the electric heating plate, thereby making the liquid heated evenly and being beneficial to improving the working efficiency of the device;

[0004] However, when the above - mentioned technology is used, once the liquid inside the tank is heated, if heating continues, the tank will be in a high - temperature state for a long time, which may lead to a decrease in metal strength and thus damage the equipment. In addition, the existing electric steam boilers may lack effective means to observe the water level, making it difficult to control the dry - burning phenomenon of the boiler. This situation not only easily causes equipment damage but also may increase the safety risks during operation.

[0005] Therefore, a dry - burning prevention protection device for an electric steam boiler is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the accompanying drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1

[0029] As Figures 1-5 shown, the embodiment of the present invention provides a dry - burning prevention protection device for an electric steam boiler, including a tank body 1. A monitoring mechanism 2 is provided at the top of the tank body 1. The monitoring mechanism 2 includes a floating ball 201, a sliding rod 202, and a fixing block 203. The floating ball 201 is arranged inside the tank body 1. The bottom of the fixing block 203 is fixedly connected to the top of the sliding rod 202. The bottom of the sliding rod 202 penetrates to the inside of the tank body 1, and the bottom of the sliding rod 202 is fixedly connected to the top of the floating ball 201. A water injection pipe 3 is fixedly communicated with the left side of the tank body 1. A sliding block 4 is provided at the top of the tank body 1. A travel groove 5 is formed on the surface of the sliding block 4. A limiting ring 6 is slidably connected to the surface of the sliding rod 202. The other side of the limiting ring 6 is slidably connected to the inside of the travel groove 5. A pressure sensor 7 is provided at the top of the limiting ring 6. Both the pressure sensor 7 and the limiting ring 6 are slidably connected to the surface of the sliding rod 202.

[0030] Through the monitoring mechanism 2, the water level can be observed in a timely manner, and the device can be operated in a timely manner. By setting the pressure sensor 7, when the water level is too low, the bottom of the fixing block 203 squeezes the top of the pressure sensor 7, causing the pressure sensor 7 to emit an electrical signal to control the overall device to stop working and protect the tank body 1.

[0031] Embodiment 2

[0032] In one embodiment, positioning blocks 8 are fixedly connected to both the front and rear sides of the limit ring 6. Cavities 9 are formed inside the two positioning blocks 8. A positioning mechanism 10 is provided inside the cavity 9. The positioning mechanism 10 includes a moving rod 1001, a positioning rod 1002, and a tension spring 1003. The moving rod 1001 is located inside the cavity 9. The lower end of the moving rod 1001 penetrates through the positioning block 8 and extends to the bottom of the positioning block 8. The tension spring 1003 is fixedly connected to the left side inside the cavity 9. The left side of the moving rod 1001 is fixedly connected to the right side of the tension spring 1003. The positioning rod 1002 is fixedly connected to the surface of the moving rod 1001. A fixing groove 11 is formed on the surface of the sliding block 4. The left side of the positioning rod 1002 penetrates through the positioning block 8 and extends to the inside of the fixing groove 11. A limiting rod 12 is fixedly connected to the inner wall of the cavity 9. The left side of the limiting rod 12 penetrates into the inside of the positioning rod 1002. A limiting groove 13 is formed inside the cavity 9. A limiting rod 14 is fixedly connected to the rear side of the moving rod 1001. The rear side of the limiting rod 14 penetrates into the inside of the limiting groove 13.

[0033] Through the positioning mechanism 10, different liquid levels can be adjusted. By pulling the moving rod 1001, the moving rod 1001 drives the positioning rod 1002 to move. It can be adjusted at any time according to the different required reserved liquid level heights, increasing the applicability of the overall device. By providing the fixing groove 11, when the positioning rod 1002 is inserted and fixed, it can be accurately inserted into the inside of the fixing groove 11 to ensure the normal use of the structure.

[0034] When the present utility model is working: First, pull the moving rod 1001. The moving rod 1001 drives the positioning rod 1002 to move. While the positioning rod 1002 is moving, it stretches the tension spring 1003, making the positioning rod 1002 move into the cavity 9. At this time, it can be adjusted at any time according to the different required reserved liquid level heights. After that, release the moving rod 1001. Through the pulling force of the tension spring 1003, the stabilizing rod is inserted back into the fixing groove 11. When the liquid inside the tank 1 drops, the floating ball 201 drives the sliding rod 202 to move downward. The sliding rod 202 drives the fixing block 203 to move downward. When the bottom of the fixing block 203 contacts the top of the pressure sensor 7, the pressure sensor 7 emits an electrical signal, causing the overall device to stop working and emit an alarm, prompting the staff to add liquid to the inside of the tank 1 in time to prevent dry burning inside the tank 1.

[0035] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
