DETAILED DESCRIPTION

[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0023] Reference Figures 1 to 4 The utility model provides a refrigeration evaporative condenser, including a box body 1, a fan 2, a water baffle 3, a sprayer 4, a condensation tube 5 and a water storage tank 6 arranged in sequence inside the box body 1, a filter plate 7 is provided between the sprayer 4 and the condensation tube 5, and the filter plate 7 includes a connecting frame 701 connected to the box body 1 in pairs, a spacer plate 702 arranged between the connecting frames 701, and a descaling agent 703 filled between the connecting frames 701 and the spacer plate 702.

[0024] One end of the sprayer 4 is connected to the water tank 6. During the spraying operation, the spray liquid in the sprayer 4 first passes through the filter plate 7 and then contacts the condenser 5. The contact between the spray liquid and the condenser 5 accelerates the heat dissipation rate. Through holes are provided on the partition plate 702 and the connecting frame 701. The spray liquid passes through the filter plate 7. The descaling agent 703 in the filter plate 7 can be an ion exchange resin, a phosphate additive, etc., to treat calcium, magnesium and other ions in the water in the spray liquid to reduce the generation of scale.

[0025] Rotating shafts 8 are provided at both ends of the connecting frame 701 , and the rotating shaft 8 passes through one side of the box body 1 and is connected to a turning mechanism 9 .

[0026] One of the rotating shafts 8 is rotatably connected to the housing 1, and the other rotating shaft 8 is connected to the flip mechanism 9. The filter screen is provided with a double-layer descaling agent 703, which is separated by a partition plate 702. When the filtering effect of one side of the filter screen decreases, the flip mechanism 9 can drive the filter plate 7 to flip, thereby improving the filtering efficiency and extending the service life of the filter plate 7.

[0027] The flip mechanism 9 is specifically provided with a rotating handle 901, which is fixed to the end of the rotating shaft 8; a limit block 902 is sleeved on the rotating shaft 8, one end of the limit block 902 is fixedly connected to the box body 1, and a fan-shaped displacement groove 9021 and a locking groove extending upward from the end of the displacement groove 9021 are provided inside the limit block 902; a locking assembly 903 is arranged in the locking groove, and a fan-shaped end 801 corresponding to the displacement groove 9021 is provided on the outer periphery of the rotating shaft 8. After the rotating shaft 8 rotates a predetermined angle, the locking assembly 903 presses down the fan-shaped end 801.

[0028] There are at least two sets of locking grooves and locking components 903. After the rotating shaft 8 rotates 180 degrees, the locking components 903 press down the fan-shaped end 801. By turning the handle 901 for manual rotation, the rotating shaft 8 drives the fan-shaped end 801 to rotate synchronously along the displacement groove 9021. The rotating shaft 8 also drives the filter plate 7 to flip. When the fan-shaped end 801 rotates from one end of the locking groove to the other end, the filter plate 7 flips 180 degrees. At this time, the fan-shaped end 801 is located below the locking component 903. The locking component 903 presses down the fan-shaped end 801 to make it fit tightly with the locking groove, and the flipping of the filter plate 7 is completed.

[0029] The locking assembly 903 is specifically provided with a telescopic spring 9031, one end of which is fixed to the bottom of the locking groove; a telescopic rod 9032 is fixedly connected to the other end of the telescopic spring 9031, and the end of the telescopic rod 9032 is hemispherical and point-contacts the surface of the fan-shaped end 801. The locking assembly 903 is close to the outer edge of the fan-shaped end 801, and the corner of the fan-shaped end 801 is provided with a circular chamfer.

[0030] The telescopic spring 9031 makes the telescopic rod 9032 fit tightly with the fan-shaped end 801 with a certain pre-tightening force, and the end of the telescopic rod 9032 contacts the outer edge of the fan-shaped end 801. When the fan-shaped end 801 rotates in the opposite direction, the telescopic rod 9032 is compressed along the arc chamfer to facilitate the reverse push of the fan-shaped end 801.

[0031] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
