[0043] Working principle: when it is necessary to recycle heat energy, hot flow carrying high-temperature heat energy enters the inside of the device through the hot flow inlet 2 at the top of the outer wall of the shell 1. Cold flow flows in synchronously through the cold flow inlet 4. After the hot flow enters, the flow direction thereof changes in a zigzag shape under the guidance of the baffle 7. The tube bundle 6 serves as a heat exchange core, the hot flow flows outside the tube bundle 6, and the cold flow flows inside the tube bundle 6, heat is transferred from the hot flow to the cold flow through the tube wall of the tube bundle 6, and the heat-exchanged cold flow and hot flow are discharged through the hot flow discharge outlet 3 and the cold flow discharge outlet 5 respectively.

At this time, the motor 9 can be energized and started, the rotation of the motor 9 drives the rotation of the gear 10, the rotation of the motor 9 is converted into the linear motion of the rack plate 14 and the fixed ring 13 due to the meshing of the gear 10 and the rack plate 14 on the inner wall of the fixed ring 13. The fixed ring 13 moves linearly along the path guided by the slide rod 12, driving the scraper 18 connected thereto to move. When encountering uneven scale, the blocking block 15 slides in the fixed ring 13, compressing the first spring 16, so that the scraper 18 always adheres to the surface of the scale.

[0045] When the cold flow enters the inside of the cold flow inlet 4, the cold flow passes through the filter screen 19 to filter impurities inside, when the filter screen 19 is used for a long time, the limiting block 20 is moved by pulling the sliding plate 24 on the surface of the cold flow inlet 4 through the rope 23. The clamping block 21 on one side of the limiting block 20 is separated from the clamping state of the 27 under the elastic force of the second spring 22, the filter screen 19 is quickly unlocked, and then the filter screen 19 can be taken out for cleaning.
