Description

Technical Field

[0001] The invention relates to energy-saving cooling equipment, and more particularly to a cooling tower and a method for installing cooling tower filler. Background Art

[0002] A cooling tower is an evaporative heat dissipation device that uses water as a circulating coolant to dissipate waste heat generated in industry or refrigeration and air conditioning. When the cooling tower is working, dry cold air enters the air inlet grille on the side of the cooling tower, passes through the spray water, passes through the filler, and finally becomes humid hot air, which is then discharged to the outside atmosphere by the fan at the top of the cooling tower.

[0003] Traditional packing installation is to use packing rods to insert the packing pieces as a whole outside the tower body, and then use lifting equipment to hoist the packing into the tower body. Due to the limitation of the installation location of the cooling tower and the long-term use of the cooling tower, dust and impurities from the outside enter the cooling tower and come into contact with the aqueous solution. They are easily accumulated in the packing part composed of the packing pieces, causing blockage and affecting the flow rate and heat dissipation effect of the aqueous solution. Traditional packing is not easy to clean.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a cooling tower and a method for installing a cooling tower filler.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a cooling tower, comprising a tower body, the tower body is provided with a cooling fan and a water distribution tray located on both sides of the cooling fan, the tower body is provided with a heat exchange component and a filling block located below the water distribution tray, the filling block is movably connected in the tower body through a filling bracket, the filling block comprises a symmetrically arranged diamond filling block, the filling bracket comprises an axis rod and a guide rod passing through the diamond filling block, and the diamond filling block is provided with a guide arc groove with the axis rod as the center and accommodating the guide rod.

[0007] By adopting the above technical scheme, the water distribution trays on both sides of the cooling fan can realize that when the circulating water in the cooling tower flows to the water distribution trays, the water flows from top to bottom through the heat exchange component for heat exchange, and then cools the aqueous solution to be cooled, and increases the contact area between water and air through the filler blocks, thereby improving the cooling effect of the circulating water, and the filler blocks adopt two symmetrically arranged diamond filler blocks, which can realize the rotation of the shaft as the rotation axis to make the two adjacent diamond filler blocks rotate in opposite directions to each other. Therefore, when maintaining the cleanliness of the filler blocks in the cooling tower, the impurities adhering to the filler blocks can be cleaned by rotating the filler blocks with the help of a high-pressure water gun.

[0008] The present invention is further configured such that the top ends or bottom ends of adjacent diamond-shaped filling blocks are deflected away from the adjacent diamond-shaped filling blocks.

[0009] By adopting the above technical solution, the top or bottom of the diamond-shaped filling blocks are deflected in directions opposite to each other, which makes it easier for people to clean two adjacent diamond-shaped filling blocks and eliminates cleaning dead corners.

[0010] The present invention is further configured such that: the lower edge corners of the diamond-shaped filling blocks are inclined toward directly below the cooling fan.

[0011] By adopting the above technical solution, the lower end corners of the diamond-shaped filling blocks are inclined toward the bottom of the cooling fan, so that the circulating water that can flow through the filling blocks is guided to the bottom of the cooling fan in the middle of the cooling tower, and the wind pressure in the middle of the tower body is changed by the cooling fan, so that the circulating water can efficiently contact with the generated airflow during the falling stage, thereby cooling the circulating water and improving the cooling cycle efficiency of the aqueous solution in the cooling tower.

[0012] The present invention is further configured as follows: the diamond-shaped filling block includes a plurality of filling pieces with diamond-shaped cross-sections; a limit stopper is slidably connected to the shaft rod with the shaft rod as the rotation center; and the end of the limit stopper is detachably connected to the guide rod.

[0013] By adopting the above technical solution, the diamond-shaped filling block is made of stacked filling sheets, which is convenient for people to separate, clean and maintain, and the setting of the limit stopper can control the distance between the filling sheets, thereby facilitating people to clean.

[0014] The present invention is further configured such that the center of gravity of adjacent diamond-shaped filling blocks is biased to be located at the corners of their movable ends.

[0015] By adopting the above technical solution, the center of gravity of the diamond-shaped filling block is biased toward the corner of its movable end, so that after the two diamond-shaped filling blocks are assembled, the center of gravity of the two adjacent diamond-shaped filling blocks are respectively located on the same vertical plane between them, which can maintain the stability of the filling block when in use, and when the diamond-shaped filling block is rotated to deflect its center of gravity to just above the shaft, the two diamond-shaped filling blocks can be separated, which is convenient for cleaning the filling block, and when resetting, it only needs to deflect the diamond-shaped filling block to automatically reset.

[0016] The present invention is further configured as follows: the limit stopper is an arc-shaped structure, the end of the limit stopper is provided with a barb portion connected to the guide rod, and the limit stopper has elastic deformation capability to provide a force for the guide rod toward the shaft rod.

[0017] By adopting the above technical solution, the set limit stopper can limit the displacement of several filling pieces by sliding. At the same time, when the limit stopper is rotated, the hook portion at the end of the limit stopper is engaged with the guide rod and provides a force for the guide rod toward the direction of the shaft rod, thereby fixing the position of the limit stopper and limiting the filling piece.

[0018] The present invention is further configured as follows: a plurality of positioning grooves engaged with the barb portions are arranged at intervals on the guide rod.

[0019] By adopting the above technical solution and setting the positioning groove, the guide rod and the barb portion are clamped together, and the limit stopper is positioned to limit the displacement of the filler sheet. The structure is simple and easy to operate.

[0020] A method for installing a cooling tower filler is used for assembling or cleaning a filler block in a cooling tower, and is characterized in that the operation steps include:

[0024] S4: Install water retaining plates. After the packing blocks are installed on both sides of the tower body symmetrically, a plurality of parallel water retaining plates are arranged along the length direction of the tower body at the top edge of the packing blocks. The bottom ends of the two water retaining plates above the packing blocks are arranged to be inclined toward each other.
