Technical Field

[0001] This utility model belongs to the technical field of falling film evaporators, and in particular relates to a falling film evaporator that enhances heat transfer efficiency. Background Technology

[0002] Falling film evaporators are primarily used to increase the concentration of a solution by heating and partially vaporizing the solvent. These evaporators are particularly suitable for low-temperature concentration operations in the food, chemical, and environmental industries, producing substances such as milk, glucose, starch, and xylose.

[0003] To achieve a tighter connection between the evaporator and the separator, a falling film evaporator with enhanced heat transfer efficiency was designed. This structure adds a convex sealing ring, a first reinforcing ring, a second reinforcing ring, and a sealing sleeve ring at the connection between the inlet pipe and the double-ended connecting pipe. This seals and reinforces the connection between the inlet pipe and the double-ended connecting pipe, resulting in a tighter connection between the evaporator and the separator. This ensures a more airtight seal during heat transfer, reducing heat loss. Utility Model Content

The top of the air inlet pipe is provided with an annular groove, and the inner cavity of the annular groove is fitted with a convex sealing ring. The surface of the air inlet pipe and the bottom surface of the double-ended connecting pipe are slidably connected with a first reinforcing ring. The two first reinforcing rings are fixedly connected to a second reinforcing ring on opposite sides, and the surfaces of the two second reinforcing rings are jointly fitted with a sealing sleeve.

[0006] Preferably, the bottom end of the double-ended connecting pipe is provided with a groove, the surface of the convex sealing ring is filled in the inner cavity of the groove, and the sealing sleeve is a rubber sealing sleeve.

[0007] Preferably, both the bottom surface of the double-ended connecting pipe and the top surface of the air intake pipe are fixedly connected with perforated reinforcing rings, and the surface of the first reinforcing ring is provided with screw holes.

[0008] Preferably, the inner cavities of the first reinforcing ring and the perforated reinforcing ring are connected by a fixing bolt, and the surface of the fixing bolt is connected by a nut.

[0009] Preferably, the inner cavity of the double-ended connecting pipe is fitted with a sealing gasket ring, and an annular groove is provided on the opposite side of each of the two second reinforcing rings.

[0010] Preferably, rubber sealing rings are fixedly connected to both the upper and lower sides of the inner cavity of the sealing sleeve, and the surface of the rubber sealing rings fills the inner cavity of the annular groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model achieves a sealing effect between the air inlet pipe and the double-ended connecting pipe by filling the surface of the convex sealing ring into the groove at the bottom of the double-ended connecting pipe. Then, by adding a sealing ring, a sealing effect is achieved between the two second reinforcing rings. This makes the connection between the evaporator and the separator more tight, so that the heat conduction between the evaporator and the separator is more sealed, thereby reducing heat loss.

[0013] 2. By setting a sealing gasket, this utility model can provide a flexible buffer between the top of the air intake pipe and the inner cavity of the double-ended connecting pipe. The special material of the sealing gasket itself also provides a tightening force when the air intake pipe and the double-ended connecting pipe are fixedly connected, which can make the connection between the air intake pipe and the double-ended connecting pipe more airtight.

[0014] 3. By using the combination of the annular groove and the rubber sealing ring, this utility model can make the inner cavity of the sealing ring and the surface of the second reinforcing ring fit more tightly after the sealing ring is fitted onto the surface of the second reinforcing ring, thus achieving a better sealing effect at the joint between the air intake pipe and the double-ended connecting pipe.

Example 2

[0026] Figure 1-6This invention illustrates an embodiment of a falling film evaporator for enhanced heat transfer efficiency, comprising: an evaporator tank 1 and a separation tank 2; both the top of the evaporator tank 1 and the separation tank 2 are connected to an inlet pipe 3, and the two inlet pipes 3 are connected by a double-ended connecting pipe 4; the top of the inlet pipe 3 has an annular groove, and the inner cavity of the annular groove is fitted with a convex sealing ring 5; the surface of the inlet pipe 3 and the bottom surface of the double-ended connecting pipe 4 are slidably connected to a first reinforcing ring 6; a second reinforcing ring 7 is fixedly connected to one side of each of the two first reinforcing rings 6; the surfaces of the two second reinforcing rings 7 are jointly fitted with a sealing collar 8; and the inner surfaces of the first reinforcing ring 6 and the perforated reinforcing ring 9 are... The cavity is connected to a common threaded bolt 10, and the surface of the bolt 10 is connected to a nut 11. The two second reinforcing rings 7 are provided with annular grooves 13 on opposite sides. Through the cooperation of the annular grooves 13 and the rubber sealing rings 14, the sealing ring 8 can be fitted onto the surface of the second reinforcing ring 7, so that the inner cavity of the sealing ring 8 can fit more tightly with the surface of the second reinforcing ring 7, and the joint between the air intake pipe 3 and the double-ended connecting pipe 4 can achieve a better sealing effect.
