[0002] Steam heaters utilize steel-aluminum composite finned tubes as the main heat exchanger element and are widely used in air separation equipment, petrochemicals, food processing, and metallurgy. They primarily use the heat released from steam to heat the required process gases. Due to the advanced composite process, the steam heater exhibits virtually no contact thermal resistance at temperatures below 210 degrees Celsius, combining the pressure resistance of steel with the high thermal conductivity of aluminum, resulting in excellent heat transfer performance. Furthermore, this design avoids direct contact between the steel tube and air, effectively improving corrosion resistance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-2This utility model provides an embodiment of a steam heater for easy descaling, comprising a housing 1, which provides protection and support for the equipment. A top cover 3 is detachably connected to the left surface of the housing 1, and a heating device 2 is fixedly installed on the left surface of the top cover 3. The heating device 2 heats the water in the housing 1 into steam and discharges it, thereby realizing the steam processing function of the equipment. A water inlet 4 is provided at the left end of the upper surface of the housing 1, and an exhaust port 5 is provided at the right end of the upper surface of the housing 1. An anti-clogging component 7 is provided at the axial center of the lower surface of the housing 1. Bases 6 are fixedly connected to both the left and right ends of the lower surface of the housing 1. A descaling component 8 is provided inside the housing 1.

[0026] Reference Figures 2-4 After the equipment has been running for a long time, the descaling component 8 is activated. The descaling component 8 includes a descaling ring 85, which is connected to the outer wall of the limiting rod 83 via a moving block 84. Slide rails 87 are fixedly connected to both the left and right surfaces of the descaling ring 85. The descaling motor 81 is activated, and the output shaft of the descaling motor 81 rotates, driving the reciprocating screw 82 to rotate. The descaling motor 81 is fixedly connected to the front end of the right surface of the housing 1, and the output shaft of the descaling motor 81 is fixedly connected to the reciprocating screw 82. The rotation of the reciprocating screw 82 causes the moving block 84 to reciprocate horizontally within the housing 1. The limiting rod 83 is fixedly connected to a groove in the inner wall of the housing 1. The front and rear of the descaling ring 85... Movable blocks 84 are fixedly connected to both ends. The movement of movable blocks 84 drives the movement of descaling rings 85, so that the descaling rings 85, together with the descaling blocks 86, can clean the inner wall of the equipment. The left surface of the movable block 84 is threaded to the outer wall of the reciprocating screw 82 at the shaft center, which prevents water vapor from adhering in the casing 1 for a long time and forming scale. The outer wall of the slide rail 87 is slidably connected to the descaling blocks 86. The outer wall of the descaling blocks 86 is in contact with the inner wall of the casing 1. When the descaling blocks 86 are squeezed, the scale is concentrated in the anti-clogging component 7 and then cleaned, which improves the cleaning effect inside the casing 1 and improves the convenience for staff to clean and maintain the scale in the machine.

[0027] Reference Figures 3-5When there is excessive scale in the waste bin 71, the anti-clogging component 7 is activated. The anti-clogging component 7 includes the waste bin 71, which is fixedly connected to the lower surface of the housing 1 at the center of the shaft. A waste pipe 73 is fixedly installed on the lower surface of the waste bin 71, and a display screen 72 is fixedly installed on the front surface of the waste bin 71. The operator can directly obtain the concentration status of scale inside the waste bin 71 through the display screen 72. The auxiliary motor 74 is activated. The auxiliary motor 74 is fixedly installed at the bottom shaft of the waste pipe 73. The rotation of the auxiliary motor 74 drives the conveying auger 75 to rotate, causing the scale to dissipate. Under the action of the conveying auger 75, the material enters the waste pipe 73 through the waste bin 71. The output shaft of the auxiliary motor 74 is fixedly installed with the conveying auger 75 to prevent scale from directly clogging the waste pipe 73. The front surface of the waste pipe 73 is connected to the drain pipe 77. The upper side of the drain pipe 77 is fixedly installed with a drain valve 76, which improves the anti-clogging performance of the equipment during the scale removal process. By opening the drain valve 76, the scale is finally discharged through the drain pipe 77. The drain valve 76 prevents the scale from flowing back and enhances the scale treatment effect of the equipment.

[0028] Working Principle: After the equipment has been running for a long time, the descaling component 8 is activated, and the descaling motor 81 is started. The output shaft of the descaling motor 81 rotates, driving the reciprocating screw 82 to rotate. The rotation of the reciprocating screw 82 causes the moving block 84 to reciprocate horizontally within the housing 1. The movement of the moving block 84 drives the descaling ring 85 to move, so that the descaling ring 85, in conjunction with the descaling block 86, cleans the inner wall of the equipment, preventing water vapor from adhering to the housing 1 for a long time and forming scale. When the descaling block 86 is squeezed, the scale is concentrated in the anti-clogging component 7 and then cleaned, improving the cleaning effect inside the housing 1 and improving the cleaning and maintenance by the staff. The machine facilitates the removal of scale. When there is excessive scale in the waste bin 71, the anti-clogging component 7 is activated. The operator can directly view the concentration of scale inside the waste bin 71 through the display screen 72. The auxiliary motor 74 is then activated, which rotates the conveying auger 75, allowing the scale to pass through the waste bin 71 into the waste pipe 73 under the action of the conveying auger 75. This prevents scale from directly clogging the waste pipe 73, improving the anti-clogging performance of the equipment during the scale removal process. By opening the drain valve 76, the scale is finally discharged through the drain pipe 77. The drain valve 76 prevents scale backflow, enhancing the equipment's scale removal effect.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
