Description

Technical Field

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

[0002] The evaporator is a very important component among the four major parts of refrigeration. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, vaporize and absorb heat to achieve the refrigeration effect. The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The plate evaporator refers to an evaporation device that uses metal plates instead of round tubes as heat transfer elements. This type of evaporator is cheap and the scale layer accumulated on the plate is easy to remove, but the stiffness and strength of the plate are much lower than that of the round tube. In order to improve the stiffness and strength of the metal plate, various heating elements with different structures have appeared, such as spiral plate heating elements, expansion plate heating elements, etc.

[0003] The plate evaporator clamps and fixes the plate by means of a fixed clamping plate and a movable clamping plate, and the fixed clamping plate and the movable clamping plate are limited and fixed by means of a plurality of long bolts. When disassembling, the long bolts need to be disassembled one by one, and the installation steps are similar, which is relatively cumbersome. Therefore, a new plate evaporator is proposed.

A support rod 5 is installed on the end of the upper guide rod 2 and the lower guide rod 3 away from the fixed pressing plate 1. A rotating rod 14 is rotatably connected to the side of the support rod 5 away from the upper guide rod 2 near the top position. One end of the rotating rod 14 passes through the support rod 5 and extends to the inside of the upper guide rod 2, and one end of the rotating rod 14 is fixedly connected to the first threaded rod 10. Rotating the rotating rod 14 drives the first threaded rod 10 to rotate, and the first threaded rod 10 rotates When the second connecting block 13 moves on the outside, it cooperates with the first connecting block 12 to slide on the connecting rod 11, driving the movable pressing plate 6 to slide on the lower guide rod 3, and adjusting the distance between the movable pressing plate 6 and the fixed pressing plate 1. A plurality of plates 7 are arranged between the fixed pressing plate 1 and the movable pressing plate 6. The top and bottom of the plates 7 are respectively provided with mounting grooves adapted to the upper guide rod 2 and the lower guide rod 3. The top of the movable pressing plate 6 is symmetrically installed with fixed plates 8, and a roller 9 is rotatably connected between the two fixed plates 8.

[0022] like Figure 3 and Figure 4 As shown, the top of the movable pressing plate 6 is provided with a slide groove adapted to the upper guide rod 2, and the slide groove at the top of the movable pressing plate 6 is fixedly connected to the first connecting block 12 and the second connecting block 13.
