Description

Technical Field

[0001] The utility model relates to the technical field of plate type rising film evaporators, in particular to a plate type rising film evaporator. Background Art

[0002] The plate evaporator is a new type of high-efficiency evaporator made of a series of corrugated metal sheets stacked together. Thin rectangular channels are formed between the plates, and heat is transferred through the plates to form thin film evaporation. The evaporated solution is heated and boiled in the evaporator and then quickly vaporized. Evaporation will drive the liquid to rise, forming a liquid film along the heat exchange wall, so that the liquid flows over the heated surface in the form of a liquid film and evaporates and vaporizes quickly, thereby shortening the heating residence time and enhancing the evaporation effect. It has the characteristics of high heat transfer coefficient, high evaporation intensity and short contact time. The special corrugated plate design makes the fluid produce high-intensity turbulence. At the same time, it can also make the cold and hot fluids flow evenly on the entire plate, without heat exchange dead zones, and can obtain good evaporation effects.

[0003] However, it still has some disadvantages. For example, when installing the metal sheets, the metal sheets need to be clamped. After all the metal sheets are installed, the staff needs to manually push the pressure plate to clamp the clamping plate to the metal sheets. Manual pushing is troublesome and inconvenient when the metal sheets need to be cleaned, which increases labor and reduces efficiency.

[0004] In order to solve the above problems, a plate type rising film evaporator is proposed in the present application. Utility Model Content

Through the right-handed threaded rod 11 and the left-handed threaded rod 13, the No. 1 connecting rod 16 and the No. 2 connecting rod 17 can be driven to be adjusted.

[0022] In this embodiment, Figure 4As shown, the outer walls of the right-handed threaded rod 11 and the left-handed threaded rod 13 are both threadedly connected with a movable connecting block 14, and the movable connecting block 14 is slidably connected to the groove 8.

[0023] Working principle:

[0024] When installing a plate-type rising film evaporator, the evaporator plate 7 needs to be installed. First, the evaporator plate 7 is placed between the movable clamping plate 6 and the installation fixed plate 3. The evaporator plate 7 is tightly fixed by moving the movable clamping plate 6. It is only necessary to start the driving motor 10 to make the right-handed threaded rod 11 and the left-handed threaded rod 13 rotate at the same time. At this time, the movable connecting blocks 14 on the outer walls of the right-handed threaded rod 11 and the left-handed threaded rod 13 move closer to each other. Since the No. 1 connecting rod 16, the No. 2 connecting rod 17 and the movable connecting block 14 are movably connected, when the movable connecting block 14 moves relative to each other, the two ends of the No. 1 connecting rod 16 and the No. 2 connecting rod 17 move relative to each other. At this time, the No. 1 connecting rod 16 and the No. 2 connecting rod 17 drive the push plate 18 to the movable clamping plate One side of the plate 6 moves until the push plate 18 contacts the movable clamping plate 6 and pushes the movable clamping plate 6 to move to one side of the evaporator plate 7 until the evaporator plate 7 is clamped between the movable clamping plate 6 and the mounting fixed plate 3. At this time, after the mounting fixed plate 3 and the fixing bolts on both sides of the movable clamping plate 6 are installed, the installation can be completed. There is no need to move the movable clamping plate 6 manually, which is more convenient, saves time, and improves the efficiency of installation and disassembly. When disassembling and cleaning the evaporator plate 7, it is only necessary to drive the motor 10 to rotate the left-handed threaded rod 13 and the movable connecting block 14 in the opposite direction, and the push plate 18 is moved away from the movable clamping plate 6 through the No. 1 connecting rod 16 and the No. 2 connecting rod 17. At this time, it is convenient to disassemble the evaporator plate 7 for cleaning.

[0025] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
