Description

Technical Field

[0001] This utility model relates to the field of evaporative cooling pad devices, and in particular to a device for recycling evaporative cooling water. Background Technology

[0002] Evaporative cooling is a widely used and highly efficient evaporative cooling technology in greenhouse cultivation. Its core principle is to utilize the physical property of water evaporation absorbing heat; the cooled air is then introduced into the greenhouse through the evaporative cooling pad, thereby regulating the greenhouse environment. Evaporative cooling pads are typically made of honeycomb paper or plastic materials, possessing a large specific surface area and good water absorption performance. However, traditional evaporative cooling systems use a single-use water flow design, directly discharging unevaporated water, failing to achieve efficient recycling and resulting in low water resource utilization. Utility Model Content

[0003] The purpose of this invention is to provide a water recycling device for evaporative cooling, which can collect and recycle the water that has not yet come down from the evaporative cooling pad and collect and utilize rainwater from the outside, thereby saving water resources.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wet curtain cooling water recycling device, characterized in that it includes a wet curtain, a circulating water tank, a water pump, and a collection device for collecting rainwater. A spray system is provided above the wet curtain, and a water collection trough is provided below the wet curtain. The circulating water tank is located below the outlet of the water collection trough. The outlet on the left side of the circulating water tank is connected to the inlet of the water pump through a first connecting water pipe. The outlet of the water pump is connected to the inlet of the spray system through a second connecting water pipe. A filter element is provided at the outlet. The collection device is externally mounted and located behind the wet curtain. The collection device is connected to the first inlet on the upper side wall of the circulating water tank through a third connecting water pipe.

[0005] Furthermore, the filter element is a filter cotton or a filter screen.

[0006] Furthermore, the collection device includes a support plate and a collection bucket. An electric telescopic rod is fixed on the support plate, and the collection bucket is located above the electric telescopic rod. A fixing plate is provided on the rear side of the collection bucket, and the other end of the electric telescopic rod is fixed on the connecting plate. Telescopic connecting rods are provided on both sides of the collection bucket, and multiple filter components are provided inside the collection bucket.

[0007] Furthermore, multiple filter components are provided, and the multiple filter components are arranged vertically.

[0008] Furthermore, the filter assembly includes a first connecting rod and a second connecting rod. The first connecting rod is hinged to both sides of the rear side wall inside the collection bucket, and the second connecting rod is hinged to both sides of the front side wall inside the collection bucket. The first connecting rod and the second connecting rod are hinged together, and filter cotton is provided on both the first connecting rod and the second connecting rod.

[0009] Furthermore, a gravity block is connected to the hinge joint of the first connecting rod and the second connecting rod.

[0010] Furthermore, the sprinkler system includes multiple nozzles and a fourth connecting water pipe. The inlet of the first connecting water pipe is connected to the outlet of the second connecting water pipe. The nozzles are distributed below the fourth connecting water pipe and are connected to the fourth connecting water pipe.

[0011] Furthermore, a second water inlet is provided on the upper side wall of the circulating water tank, and a float switch for controlling the water intake of the second water inlet is provided inside the circulating water tank.

[0012] The beneficial effects of this invention are as follows: Water from the circulating water tank is pumped out and evenly sprayed onto the wet curtain via a spray system. Under gravity, the water slowly flows down the surface of the wet curtain. When hot outside air flows over the wet curtain, it exchanges heat with the moist surface, causing the water to evaporate and absorb heat, thus lowering the air temperature. The cooled air then enters the room, achieving cooling. The flowing water is collected in the circulating water tank, filtered by a filter, and then pumped back for recycling. If it rains, rainwater can be collected using a collection device. An electric telescopic rod drives the collection bucket and the filter cotton inside to open, filtering the rainwater. The rainwater then flows directly into the circulating water tank by gravity, replenishing the existing water supply. This forms a water circulation system, achieving both cooling and water conservation. Attached Figure Description
