Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and in particular to a high-efficiency boiler-type steam electric heater. Background Technology

[0002] In the field of heating equipment, traditional heating equipment mostly uses coal-fired steam boilers or coal-fired water boilers for heating, and then heat exchangers are used to exchange heat in the room to keep the room temperature within a constant range. This heating method requires coal boilers, stokers, etc. Coal-fired steam boilers or coal-fired water boilers are complicated to use, have high labor costs, and pose significant safety hazards. Therefore, the emergence of electric heating boilers can greatly reduce the above-mentioned defects.

[0003] Patent number CN217082501U provides an electric heater for boiler steam, belonging to the field of electric heater technology. It includes a boiler body, a heating component, a stirring component, and a driving component. The heating component is disposed inside the boiler body for heating water. The driving component is installed inside the boiler body, and the stirring component is disposed on one side of the driving component. The driving component drives the stirring component to rotate, thereby agitating the water inside the boiler body. In this embodiment, the heating component heats the water inside the boiler body to generate steam. The driving component drives the stirring component to rotate, thus agitating the water inside the boiler body, improving the contact effect between the water and the heating component, thereby improving the heating effect of the water. Compared with the prior art, this achieves efficient heating of the water, with advantages of good heating effect and high heating efficiency.

[0004] However, the aforementioned type of electric heater for boiler steam still has the following shortcomings:

[0005] In the above-mentioned device, the steam needs to pass through the drive component during the rising process, and the steam needs to pass through between several blades, which greatly reduces the steam rate. At the same time, when passing through the fan-type drive component, the steam temperature is easily reduced, which leads to condensation loss and increases energy consumption. In view of this, we propose a high-efficiency boiler-type steam electric heater. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high-efficiency boiler-type steam electric heater to solve the technical problems in the current device where the steam needs to pass through the drive component during the rising process, and the steam needs to pass through several blades, which greatly reduces the steam rate. At the same time, when passing through the fan-type drive component, the steam temperature is easily reduced, thereby causing condensation loss and increasing energy consumption.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: designing a high-efficiency boiler-type steam electric heater, including an electric boiler body, wherein an auxiliary mechanism is provided in the middle of the electric boiler body;

[0008] The auxiliary mechanism includes a positioning frame, which is fixed to the top center of the electric boiler body. A motor is installed inside the positioning frame, and a rotating shaft is connected to the movable end of the motor. Several stirring rods are evenly distributed on the surface of the rotating shaft. A scraper is fixed to the end of each stirring rod away from the rotating shaft. A metal wire mesh is installed above the top of the stirring rods.

[0009] Preferably, the rotating shaft is fixedly connected to a plurality of stirring rods, and the stirring rods have a teardrop-shaped cross-section.

[0010] Preferably, the scraper is fixedly connected to the rotating shaft via a metal wire mesh, and the highest water level inside the main body of the electric boiler is located at the horizontal center of the metal wire mesh.

[0011] Preferably, the electric boiler body includes a boiler body, a bracket is fixedly mounted on the outside of the boiler body, a water inlet is provided on one side of the top of the boiler body, a sealing cover is provided on the inner side of the top of the water inlet, an exhaust port is provided on the other side of the top of the boiler body, a flange is fixedly mounted on the outer side of the top of the exhaust port, and a drain port is provided at the bottom of the boiler body.

[0012] Preferably, the outer side of the scraper is in contact with the inner wall of the boiler body.

[0013] Preferably, both the water inlet and the drain outlet are equipped with valves, and the water inlet and the sealing cover are connected by threads.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model effectively drives the rotating shaft to rotate via a motor, thereby driving the stirring rod and scraper to rotate. The rotating stirring rod agitates the water source, improving the heating effect. At the same time, the teardrop-shaped stirring rod can effectively balance the stirring efficiency and steam flow resistance by delaying boundary layer separation, reducing the wake region, and reducing pressure resistance, thus reducing energy loss. The rotating scraper, in conjunction with the wire mesh, can effectively break up the foam layer generated by stirring, release trapped steam, and inhibit coking. Furthermore, the scraper can assist in subsequent slag removal and sewage discharge treatment.

[0016] 2. The sealing cover on the inner side of the top of the water inlet in this utility model is used to seal and protect the opening of the water inlet, reducing the possibility of foreign objects entering the water inlet. The steam transmission pipeline and the exhaust port can be effectively connected by fasteners and flanges. During subsequent slag removal, the impurities cleaned from the inside of the boiler body can be discharged through the drain port. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] A high-efficiency boiler-type steam electric heater, see [link / reference] Figures 1 to 4 It includes an electric boiler body 1, and an auxiliary mechanism 2 is provided in the middle of the electric boiler body 1;

[0026] The auxiliary mechanism 2 includes a positioning frame 201, which is fixed to the top middle of the electric boiler body 1. A motor 202 is installed inside the positioning frame 201. A rotating shaft 203 is connected to the movable end of the motor 202. Several stirring rods 204 are evenly distributed on the surface of the rotating shaft 203. The rotating shaft 203 and the stirring rods 204 are fixedly connected. The cross-section of the stirring rods 204 is teardrop-shaped. A scraper 205 is fixedly connected to the end of the stirring rod 204 away from the rotating shaft 203. A metal wire mesh 206 is provided above the top stirring rods 204. Furthermore, the scraper 205 is fixedly connected to the rotating shaft 203 through the metal wire mesh 206. The highest water level line inside the electric boiler body 1 is located at the middle of the horizontal direction of the metal wire mesh 206. This invention effectively drives the rotating shaft 203 to rotate via the motor 202, thereby driving the stirring rod 204 and scraper 205 to rotate. The rotating stirring rod 204 agitates the water source, improving the heating effect. At the same time, the teardrop-shaped stirring rod 204 can effectively balance the stirring efficiency and steam flow resistance by delaying boundary layer separation, reducing the wake region, and reducing pressure difference resistance, thus reducing energy loss. The rotating scraper 205, in conjunction with the metal wire mesh 206, can effectively break the foam layer generated by stirring, release trapped steam, and inhibit coking. Furthermore, the scraper 205 can assist in subsequent slag removal and sewage discharge treatment.

[0027] It is worth noting that the main body 1 of the electric boiler includes a boiler body 101, wherein the outer side of the scraper 205 is attached to the inner wall of the boiler body 101, a bracket 102 is fixedly installed on the outer side of the boiler body 101, a water inlet 103 is provided on one side of the top of the boiler body 101, a sealing cover 104 is provided on the inner side of the top of the water inlet 103, an exhaust port 105 is provided on the other side of the top of the boiler body 101, a flange 106 is fixedly installed on the outer side of the top of the exhaust port 105, and a drain port 107 is provided at the bottom of the boiler body 101. Furthermore, valves are provided on both the water inlet 103 and the drain port 107, and the water inlet 103 and the sealing cover 104 are connected by threads. In this utility model, the sealing cover 104 on the inner side of the top of the water inlet 103 is used to seal and protect the opening of the water inlet 103, reducing the possibility of foreign objects entering the interior of the water inlet 103. The steam transmission pipeline can be effectively connected to the exhaust port 105 by fasteners and flange 106. During subsequent slag cleaning, the impurities cleaned from the interior of the boiler body 101 can be discharged through the drain port 107.

[0028] Working principle: Water is injected into the boiler body 101 through the inlet 103 until the water level is in the middle of the horizontal direction of the wire mesh 206. Then, the opening of the inlet 103 is sealed and protected by the sealing cover 104. The steam transmission pipe is connected to the exhaust port 105 through fasteners and flange 106. At the same time, the boiler body 101 is powered on for heating. The motor 202 drives the rotating shaft 203 to rotate, which in turn drives the stirring rod 204 and scraper 205 to rotate. The rotating stirring rod 204 agitates the water source to improve the heating effect. At the same time, the teardrop-shaped stirring rod 204 balances the stirring efficiency and steam flow resistance by delaying boundary layer separation, reducing the wake zone, and reducing pressure resistance, thereby reducing energy loss. The rotating scraper 205, in conjunction with the wire mesh 206, can break the foam layer generated by stirring, release trapped steam, and inhibit coking. The scraper 205 can also assist in subsequent slag removal and sewage discharge. The impurities cleaned out of the boiler body 101 can be discharged through the sewage outlet 107.
