Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline electric heaters, specifically a high-efficiency adjustable pipeline electric heater. Background Technology

[0002] Pipeline electric heaters are electric heating devices used to heat pipelines or internal media. They are mainly used for steam heating in water systems such as heating, factory process water, and power plant raw water.

[0003] Pipeline electric heaters are typically designed with adjustable temperature and power. They consist of several parts, including multiple tubular electric heating elements and a cylinder. During the heating process, the low-temperature fluid medium enters the inlet through the pipeline under pressure and flows along the heat exchange channel inside the air heating container, causing the temperature of the heated medium to rise.

[0004] During the heating process inside a pipe, the fluid's physical properties, such as viscosity and density, change with temperature. This can easily lead to uneven distribution of the fluid inside the pipe, resulting in uneven heat distribution. Uneven heat distribution reduces heat transfer efficiency, increases energy loss, and thus affects heating efficiency.

[0005] Therefore, this utility model provides a high-efficiency adjustable pipeline electric heater. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 6As shown in the figure, a high-efficiency adjustable pipeline electric heater according to an embodiment of the present invention includes a pipeline body 1; an air inlet pipe 10 and a drain pipe 11 are provided in the middle of the pipeline body 1; the air inlet pipe 10 and the drain pipe 11 are arranged opposite to each other; a liquid inlet pipe 12 is provided at the end of the pipeline body 1; a heater body 14 is installed at the end of the pipeline body 1 away from the liquid inlet pipe 12; a mounting base 13 is provided in the middle of the heater body 14; a disturbance component 2 and a monitoring component 3 are installed inside the pipeline body 1; the disturbance component 2 includes a motor 21; the motor 21 is installed at the end of the pipeline body 1; the output end of the motor 21 passes through the pipeline body 1. At the end; a gear 23 is fixedly connected to the output end of the motor 21; a gear ring 22 is meshed in the middle of the gear 23; the gear ring 22 is rotatably connected to the end of the pipe body 1; the gear ring 22 is located inside the pipe body 1; a rotating seat 24 is fixedly connected to the end of the pipe body 1 away from the gear ring 22; a spiral plate 25 is fixedly connected to the middle of the gear ring 22 and the rotating seat 24; multiple metal plates 26 are fixedly connected to the middle of the spiral plate 25; the multiple metal plates 26 are equidistantly distributed; a cleaning component 4 is installed in the middle of the disturbance component 2; during operation, the heater body 14 is installed through the mounting seat 13 through the end of the pipe body 1, and the pipe body is started. 1. Internal medium flow, power is turned on, target temperature and over-temperature alarm threshold are set by the temperature controller, and the temperature of heater body 14 is adjusted. During the heating process, the heat is evenly distributed by the disturbance component 2, so that the medium is heated quickly. At the same time, the liquid level inside the pipe body 1 is monitored by the monitoring component 3. When the heater body 14 heats the inside of the pipe body 1, the control motor 21 is turned on, so that its output end drives the gear 23 to rotate. During the rotation of the gear 23, the gear ring 22 rotates at the end of the pipe body 1. Part of the heat generated by the heater body 14 is transferred to the surface of the metal plate 26. The metal plate 26 transfers heat to the medium in various parts as the spiral plate 25 rotates. The spiral plate 25 drives the rotating seat 24 to rotate at the end of the pipe body 1, which disturbs the internal medium and makes the heat transfer efficient. Through the above structure, the spiral plate 25 generates strong disturbance to the fluid in the pipe body 1, forming a complex turbulent state, so that the heat distribution between the fluid parts is uniform, increasing the contact area between the fluid inside the pipe body 1 and the heating surface, accelerating the heat exchange rate between fluid layers of different temperatures inside the pipe body 1, reducing the temperature gradient, and thus improving the heat transfer efficiency.

[0026] like Figure 2 and Figure 3As shown, the monitoring component 3 includes a fixed rod 31; the fixed rod 31 is fixed inside the pipe body 1; the fixed rod 31 is located at the bottom of the pipe body 1; a float 32 is installed in the middle of the fixed rod 31; a probe 34 is installed in the middle of the pipe body 1; a sensor 33 is installed in the middle of the probe 34; the sensor 33 is located outside the pipe body 1; an alarm 35 is installed in the middle of the sensor 33; during operation, the float 32 moves upward with the medium liquid level. When the liquid level gradually decreases, the float 32 descends in the middle of the fixed rod 31. When the liquid level is low, the bottom of the float 32 contacts the probe 34, and the probe 34 transmits a signal, which triggers the alarm 35 through the sensor 33, reminding the staff to handle the situation in time. Through the above structure, the liquid level or fluid presence inside the pipe body 1 can be monitored in real time, reducing the occurrence of dry burning inside the pipe body 1, reducing the damage of the heating element to high temperature, and reducing the maintenance cost and replacement frequency of the equipment.

[0027] like Figure 2 and Figure 4 As shown, the cleaning component 4 includes multiple springs 41; multiple springs 41 are fixedly connected to the middle of the spiral plate 25; mounting rods 42 are fixedly connected to the ends of multiple springs 41; mounting grooves 43 are opened in the middle of the mounting rods 42; scrapers 44 are installed in the middle of the mounting grooves 43; nuts 45 are threadedly connected to the ends of the mounting rods 42; during operation, the scrapers 44 are installed in the middle of the mounting grooves 43 from one end of the mounting rods 42, and the nuts 45 are rotated to fix the scrapers 44 inside the mounting rods 42. The elasticity of the springs 41 makes the scrapers 44 continuously adhere to the inner wall of the pipe body 1. The scrapers 44 clean the inner wall of the pipe body 1 as the spiral plate 25 rotates. Through the above structure, the attachments on the inner wall of the pipe body 1 are removed in time, reducing the accumulation of impurities in the pipe to form a thick layer of dirt, keeping the inner wall of the pipe body 1 clean, reducing the formation of scale from minerals in the water on the inner wall of the pipe body 1, reducing the roughness of the inner wall of the pipe, and reducing fluid flow resistance.

[0028] like Figure 1 and Figure 6 As shown, two positioning seats 5 are fixed to the end of the pipe body 1; the two positioning seats 5 are arranged on both sides of the mounting seat 13; a rubber pad 51 is fixed to the inner wall of the positioning seat 5; two positioning blocks 52 are fixed to the outer wall of the mounting seat 13; the two positioning blocks 52 are arranged in the middle of the corresponding positioning seats 5; when the heater body 14 is installed, the two positioning blocks 52 are placed in the corresponding positions of the positioning seats 5. The rubber pad 51 is flexible and the positioning block 52 is interference fit. After the mounting seat 13 is connected to the end of the pipe body 1, it is positioned by the positioning seats 5 and the positioning blocks 52. The above structure can make the end of the heater body 14 loose when the pipe body 1 is subjected to fluid impact, vibration or its own thermal expansion and contraction, thus maintaining the connection stability between the heater body 14 and the pipe.

[0029] like Figure 5 As shown, a flow guide 6 is provided inside the pipe body 1; the flow guide 6 is located at the bottom of the pipe body 1; both ends of the flow guide 6 are inclined surfaces; both sides of the flow guide 6 are inclined surfaces; during operation, when liquid is discharged from inside the pipe body 1, the liquid passes through the flow guide 6 and enters the drain pipe 11. The flow guide 6 guides the liquid, and the above-mentioned structure allows the flow guide 6 to drain the residual liquid when the machine is stopped, effectively reducing the problem of freezing and cracking caused by residual liquid when the ambient temperature is low in winter.

[0030] like Figure 1 As shown, a heat insulation cover 7 is provided in the middle of the pipe body 1; the heat insulation cover 7 is fixed to the outer wall of the pipe body 1; when the medium inside the pipe body 1 is heated during operation, the heat insulation cover 7 isolates the heat exchange between the inside of the pipe body 1 and the external airflow. The above structure can effectively reduce the heat loss inside the pipe body 1 and maintain the temperature inside the pipe body 1.

[0031] During operation, the heater body 14 is installed through the mounting base 13 at the end of the pipe body 1. The flow of the medium inside the pipe body 1 is initiated, the power is turned on, and the target temperature and over-temperature alarm threshold are set via the temperature controller. The temperature of the heater body 14 is adjusted accordingly. During the heating process, the disturbance component 2 promotes uniform heat distribution, allowing the medium to be heated rapidly. Simultaneously, the monitoring component 3 monitors the liquid level inside the pipe body 1. When the heater body 14 heats the inside of the pipe body 1, the control motor 21 is turned on, causing its output end to drive the gear 23 to rotate. During the rotation of the gear 23, the gear ring 22 rotates at the end of the pipe body 1. Some of the heat generated by the heater body 14 is transferred to the surface of the metal plate 26. The metal plate 26, along with the rotation of the spiral plate 25, transfers heat to various parts of the medium. The spiral plate 25 drives the rotating seat 24 to rotate simultaneously at the end of the pipe body 1, disturbing the internal medium and ensuring efficient heat transfer. The float 32 moves upward with the liquid level. As the liquid level gradually decreases, the float 32 descends in the middle of the fixed rod 31. When the float 32 is at a low temperature, its bottom contacts the probe 34. The probe 34 transmits a signal, which, through the sensor 33, activates the alarm 35, alerting staff to handle the situation promptly. The scraper 44 is then installed from one end of the mounting rod 42 into the middle of the mounting groove 43. The nut 45 is rotated to the corresponding end of the mounting rod 42, fixing the scraper 44 inside the mounting rod 42. The elasticity of the spring 41 keeps the scraper 44 in continuous contact with the inner wall of the pipe body 1. As the spiral plate 25 rotates, the scraper 44 cleans the inner wall of the pipe body 1, thus cleaning the heater. When the body 14 is installed, the two positioning blocks 52 are placed in the corresponding positions of the positioning seat 5. The rubber pad 51 is flexible and the positioning block 52 is interference fit. After the mounting seat 13 is connected to the end of the pipe body 1, it is positioned by the positioning seat 5 and the positioning block 52. When the liquid inside the pipe body 1 is discharged, the liquid is concentrated into the drain pipe 11 through the guide channel 6. The liquid is guided by the guide channel 6. When the medium inside the pipe body 1 is heated, the heat exchange between the inside of the pipe body 1 and the external airflow is isolated by the heat insulation cover 7.
