[0002] A cooling tower is a device that uses water as a circulating coolant, absorbing heat from the system and discharging it into the atmosphere to lower the water temperature. Cooling tower fill is a key component in a cooling tower, increasing heat dissipation, extending the residence time of the cooling water, and increasing the heat exchange area, thereby improving heat exchange efficiency. However, after prolonged use, the fill will become covered with dirt, which can hinder the normal flow of water.

[0003] The current method for cleaning packing is generally to place the packing in a horizontal shape in a cleaning device and spray it with water. The water flow on the surface of the horizontal packing is poor, and dirt is easily retained on the surface of the packing, resulting in low cleaning efficiency of the packing.

[0029] When in use, the cooling tower filler to be cleaned is placed on the multiple connecting rods 16 of the carrier through the material hole 3, the upper part of the filler contacts the bristles 9 at the lower part of the annular belt 5, and the screw rod 17 is rotated. When the screw rod 17 rotates, the two clamping rods 15 move relative to each other until the two clamping rods 15 clamp the filler, and the screw rod 17 stops rotating. Therefore, the utility model can limit fillers of different widths, thereby increasing the scope of use;

[0030] Multiple spray heads spray water or cleaning agent to the filler to clean the filler surface. At the same time, the motor 14 drives the screw 13 to rotate clockwise (the clockwise rotation of the screw 13 is Figure 2clockwise rotation of the screw rod two 17, the two clamping rods 15 move away from each other, the limiting of the filler is released, the filler is taken out, the filler is reversed, and then is placed on the bearing frame in the box 1 again, and the above steps are repeated to clean the other side of the filler. Figure 2 from the left to the right, the slider 12 on the inner wall of the rear circular tube 8 is in the helical groove 11, and the slider 12 slides along the helical groove 11 while moving from the left to the right with the circular tube 8, thereby driving the rear circular tube 8 to rotate counterclockwise (the counterclockwise rotation of the rear circular tube 8 is shown in the perspective view of FIG. 6), the annular belt 5 rotates counterclockwise with the rear circular tube 8, and the bristles 9 at the lower part of the annular belt 5 brush the filler from the left to the right and also brush the filler backward, thereby driving the dirt remaining on the surface of the filler backward, and the dirt is driven to fall into the box 1 below the bearing frame through the rear end of the filler or the through slot 18 on the rear clamping rod 15. Similarly, when the motor 14 drives the screw rod two 17 to rotate counterclockwise, the bristles 9 drive the dirt remaining on the surface of the filler forward, and the dirt is driven to fall into the box 1 below the bearing frame through the front end of the filler or the through slot 18 on the front clamping rod 15; the sewage in the box 1 below the bearing frame flows out through the liquid outlet pipe 23.

[0031] After the motor 14 stops working, the screw rod two 17 is reversed to move the two clamping rods 15 away from each other, thereby releasing the limiting of the filler. After the filler is taken out, the filler is reversed and then is placed on the bearing frame in the box 1 again, and the above steps are repeated to clean the other side of the filler.
