Detailed Description

In order that those skilled in the art will better understand the present utility model, a technical solution of the embodiments of the present utility model will be clearly and completely described below, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

As shown in fig. 1 to 5.

The utility model provides a high-efficient plate heat exchanger unit, includes posterior lateral plate 1 and preceding curb plate 2, and is equipped with slab group 3 between posterior lateral plate 1 and preceding curb plate 2, through screw rod 4 fixed connection, its characterized in that between posterior lateral plate 1 and the preceding curb plate 2: the outside of preceding curb plate 2 is equipped with rose box 21, and connection closing cap 22 is installed through the cooperation of connecting bolt 23 and fixation nut 24 in the outside of this rose box 21, the outside of preceding curb plate 2 and with the junction of rose box 21 be equipped with the draw-in groove 25 of the frame looks block of rose box 21, the inside of rose box 21 is equipped with filter screen 26, the fluting 27 that the diameter is greater than connecting bolt 23 has been seted up respectively to the both ends top that contacts with connecting bolt 23 in the rose box 21.

When the filter box is installed, firstly, the frame of the filter box 21 corresponds to the clamping groove 25 in the front side plate 2, one end of the filter box 21 is clamped into the clamping groove 25, one side, provided with a groove, of the filter box 21 faces one side of the connecting sealing cover 22, then, the connecting sealing cover 22 is installed, the bulge on the inner side of the connecting sealing cover 22 is clamped into the groove on the outer side of the filter box 21, finally, the connecting screw 23 sequentially penetrates through the filter box 21 and the connecting sealing cover 22 from the inner side of the front side plate 2, and the filter box 21 is fixed through the fixing nut 24, so that the filter box 21 is extruded and fixed between the front side plate 2 and the connecting sealing cover 22.
