Description

Technical Field

[0001] This utility model relates to the technical field of sugar beet making equipment, specifically to a sugar water heater. Background Technology

[0002] In the beet sugar production process, beet sugar factories mainly rely on two heating devices: steam heaters and heat exchangers. Steam heaters efficiently and evenly transfer heat to beet syrup using saturated steam, accelerating sugar desorption and increasing sugar content. Heat exchangers, on the other hand, utilize the principle of heat exchange to allow high-temperature hot water or steam to exchange heat with low-temperature beet syrup, gently raising the syrup temperature.

[0003] Traditional heat exchangers have a short heat exchange time, mainly because although the internal piping is designed with serpentine pipes to extend the flow path of the sugar water, the short residence time of the hot water in the tank leads to significant heat energy consumption due to the need for a continuous supply of hot water and the rapid discharge of hot water. A single heater cannot meet the heating demand, requiring multiple heating devices connected in series to achieve the required heating temperature. Furthermore, the design, while aiming for a longer residence time of hot water in the tank, results in a complex internal structure. During maintenance, internal water drainage is difficult, requiring disassembly for complete drainage. After disassembly, the internal water cannot be controlled and may leak into the surrounding environment. If the water is not completely cooled, it can even scald maintenance personnel. Utility Model Content:

[0004] To address the shortcomings of existing technologies, this utility model provides a sugar water heater. This heater features a looped pipeline to extend the flow path of the sugar water, and also includes cavities to prolong the time the hot water spends within the heater, thereby improving the heating efficiency.

After the drain hole 4.1 is opened, water will enter the inner side of the drain pipe 4 along the drain hole 4.1, and the water entering the inner side of the drain pipe 4 will then be discharged from the guide holes 5.1 of the inner sealing pipe 5. A movable sealing element is provided between the inner sealing pipe 5 and the drain pipe 4.

Figure 7 The flow direction is maintained, which prolongs the time that sugar water and hot water remain in tank 1. When operation is required, the valves at the inlet 1.1 and outlet 1.2 are closed. Water remains in tank 1. After the drive motor 8 is rotated to a specified angle, the water baffle 5.2 is no longer aligned with the drain hole 4.1, and the drain hole 4.1 opens to drain water. Water first enters the drain hole 4.1 and then enters along the guide hole 5.1 on the inner sealing pipe 5. The water in the inner cavity 10 of the circulation baffle 3 is discharged. After the water baffle 5.2 is opened, the water in the outer cavity 10 of the circulation baffle 3 first enters the drain trough 12. The water in the drain trough 12 then enters the drain pipe 4 through the drain hole 4.1 and finally enters through the guide hole 5.1 of the inner sealing pipe 5. The drainage work is finally completed on the outer side of the circulation baffle 3 through the drain trough 12 below the bottom plate 11.
