Technical Field
[0001] This utility model belongs to the field of fan technology, specifically a high-speed evaporative cooling fan of the rotor impeller type. Background Technology
[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. In China, "fan" is a common abbreviation for gas compression and gas transportation machinery. The term "fan" usually includes ventilators, blowers, and wind turbines. In high-temperature environments such as industrial plants, agricultural greenhouses, and large public places, there is an urgent need for fans as efficient and energy-saving cooling equipment.
[0003] Although existing fans have low energy consumption, they are limited by their structure and airflow organization, resulting in slow cooling speeds, which makes it difficult to meet the demand for rapid cooling. Utility Model Content

[0006] The fixing mechanism includes an inner frame located inside the housing, with a wet curtain installed on the inner side of the inner frame. A vertical plate is fixedly connected inside the housing, and a positioning plate is fixedly connected to the side of the inner frame near the vertical plate, penetrating through the vertical plate. Two positioning rods are symmetrically fixedly connected to the outer side of the housing, and an outer frame is movably sleeved between the two positioning rods. A sealing gasket is fixedly connected to the side of the outer frame near the housing, and the sealing gasket fits against the housing. A filter plate is fixedly connected to the inner side of the outer frame, and a guide hopper is fixedly connected to the side of the outer frame near the wet curtain. Two limiting rods are symmetrically fixedly connected to the outer frame, with the ends of the two limiting rods away from the outer frame abutting against the inner frame.
[0007] Preferably, two L-shaped plates are symmetrically rotatably connected to the outer frame, and each L-shaped plate is fixedly connected with a retaining ring.
[0008] Preferably, the outer side of the housing is fixedly connected with a first fixed ring and a second fixed ring.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example 1, by Figure 1 This utility model relates to a high-speed evaporative cooling fan with a rotary impeller, including a housing 1, a fixing mechanism 2 on the housing 1, a water supply mechanism 3 on the fixing mechanism 2, a rotary impeller 4 inside the housing 1, and a motor installed inside the housing 1. The rotary impeller 4 is mounted on the motor. When the rotary impeller 4 rotates at high speed, it generates strong suction and thrust through the aerodynamic effect of the curved blade surface, forming a high-speed airflow. The rotary structure can reduce airflow turbulence loss and increase air volume and air pressure, making it suitable for scenarios that require rapid delivery of large amounts of air.
[0026] Specifically, by Figure 2-5The fixing mechanism 2 includes an inner frame 201 located inside the housing 1. A wet curtain 202 is provided on the inner side of the inner frame 201. A vertical plate 203 is fixedly connected inside the housing 1. A positioning plate 204 is fixedly connected to the side of the inner frame 201 near the vertical plate 203, penetrating the vertical plate 203. Two positioning rods 2012 are symmetrically fixedly connected to the outer side of the housing 1. An outer frame 205 is movably sleeved between the two positioning rods 2012. A sealing gasket 2011 is fixedly connected to the side of the outer frame 205 near the housing 1. The sealing gasket 2011 is connected to the machine... The outer frame 205 is fitted with a filter plate 209 fixedly connected to the inner side of the casing 1. The filter plate 209 is located at the air inlet of the casing 1 to facilitate the filtration of the air entering the casing 1. A dustproof net is installed at the air outlet of the casing 1 by bolts to prevent dust. A guide bucket 208 is fixedly connected to the side of the outer frame 205 near the wet curtain 202. By setting the guide bucket 208, the airflow can be guided to be evenly distributed across the entire surface of the wet curtain 202, avoiding uneven evaporation caused by excessively strong or weak local airflow. Two symmetrically fixed points are fixedly connected to the outer frame 205. Two limiting rods 2010, each with its end away from the outer frame 205, abut against the inner frame 201. Two L-shaped plates 207 are symmetrically rotatably connected to the outer frame 205, each L-shaped plate 207 having a fixed insert ring 2013. A first fixed ring 2014 and a second fixed ring 2015 are fixedly connected to the outer side of the housing 1. Two guide posts 2018 are symmetrically fixed between the first fixed ring 2014 and the second fixed ring 2015. A movable ring 206 is movably sleeved between the two guide posts 2018. The outer side of the movable ring 206... The two L-shaped plates 207 are respectively inserted into the two clearance grooves 2020. Two rods 2019 are symmetrically fixed to the outer side of the movable ring 206. The two rods 2019 are respectively inserted into the two rings 2013. The fixed ring 2014 is rotatably connected to the side of the fixed ring 2015 near the fixed ring 2015. The end of the screw 2016 away from the fixed ring 2014 passes through the fixed ring 2015 and is fixedly connected to the handwheel 2017. The movable ring 206 is threaded onto the outer side of the screw 2016.
[0027] In use, first place the inner frame 201 inside the housing 1, so that the positioning plate 204 passes through the upright plate 203. Then, fit the outer frame 205 onto the outside of the two positioning rods 2012 until the sealing gasket 2011 is in contact with the housing 1. Then rotate the two L-shaped plates 207 until they enter the two clearance slots 2020 respectively. Then rotate the handwheel 2017 to drive the screw 2016 to rotate and drive the movable ring 206 to slide along the two guide posts 2018. At the same time, the two insertion rods 2019 move horizontally until they are inserted into the two insertion rings 2013 respectively, fixing the outer frame 205 and the inner frame 201. This realizes the installation of the filter plate 209 for air filtration. At the same time, the wet curtain 202 is fixed inside the housing 1. When the airflow passes through the wet curtain 202, it comes into full contact with water. The water evaporates and absorbs heat, which lowers the air temperature and finally meets the need for rapid cooling.
[0028] Specifically, by Figure 6 The water supply mechanism 3 includes a spray pipe 301 fixed inside the inner frame 201. Multiple nozzles 304 are provided at equal intervals at the bottom of the spray pipe 301, all located above the wet curtain 202. A water supply pipe 303 is fixedly sleeved on the inner side of the upright plate 203. The top end of the water supply pipe 303 extends to the outer side of the housing 1. A side pipe 305 is fixedly connected to the outer side of the spray pipe 301. The side pipe 305 is sleeved on the outer side of the water supply pipe 303. A sealing ring 302 is fixedly connected to the side of the upright plate 203 near the spray pipe 301. The side pipe 305 is in contact with the sealing ring 302.
[0029] In use, when the inner frame 201 is placed inside the housing 1 so that the positioning plate 204 passes through the upright plate 203, the side tube 305 is sleeved on the outside of the water supply pipe 303 until the side tube 305 is in contact with the sealing ring 302, ensuring the sealing between the side tube 305 and the water supply pipe 303. Then, the top of the water supply pipe 303 is connected to the water pump, so that water enters the spray pipe 301 through the water supply pipe 303 and the side tube 305 and is sprayed out from each nozzle 304. Finally, the water is evenly covered on the surface of the wet curtain 202 to ensure that the wet curtain 202 is continuously moist.
