Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial technology, in particular to an industrial fan with high-efficiency refrigeration. Background Art
[0002] With the continuous development of society and the continuous advancement of science and technology, fans as refrigeration devices are becoming more and more well-known. Since fans achieve the effect of cooling by changing the flow rate in the air, there is a method to increase the wind force to improve the cooling effect. However, when the external air temperature is very high, increasing the wind speed often does not have a cooling effect. In order to solve the cooling problem, water-cooled fans were invented. However, since they will consume a lot of water resources, in order to solve this drawback, a high-efficiency cooling industrial fan was invented to improve the cooling effect.
[0003] Existing industrial refrigeration fans often use the principle of water evaporation to absorb heat during the cooling process to reduce the temperature of the air blown out by the fan. However, this method often causes the cooling effect to decrease over time due to long-term lack of water replacement. At the same time, additional power is required in the fan to inject water into the condenser plate, which is not in line with the contemporary theme of energy conservation. Utility Model Content
[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. When performing the refrigeration process, the existing refrigeration industrial fans often reduce the temperature of the blown air by absorbing heat through the evaporation of water. However, this method often causes the cooling effect to decrease over time due to long-term non-replacement of water. At the same time, additional power is required in the fan to inject water into the condensing plate, which is not in line with the theme of energy conservation. Instead, a high-efficiency refrigeration industrial fan is proposed.

[0008] Preferably, a refrigeration component is installed in the air outlet chamber, and the refrigeration component also includes a piston cylinder, a second piston plate, an airbag, and a circular push rod. The piston cylinder is fixedly connected to one side of the air outlet chamber, one end of the airbag is fixedly connected to the end of the piston cylinder close to the water tank, the second piston plate is slidably connected to the end away from the airbag, one end of the circular push rod is slidably connected to the piston cylinder, and a spring is installed between the outer surface of the circular push rod and the piston cylinder.

[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. When the wind in the bellows is discharged through the air outlet box, the high-speed airflow will push the second fan blade to move and drive the second rotating shaft to rotate, pushing the second piston plate to move in the piston cylinder through the connecting rod and the second rotating rod, and allowing the gas in the piston rod to enter the airbag. The airbag expands and pushes the circular push rod and the first piston plate to move. The first piston plate squeezes the water in the water tank, so that the water in the water tank can be injected into the condensation plate at a certain pressure, eliminating labor and additional power devices, greatly reducing economy and energy.
[0015] 2.

At the same time, the water in the water flow trough will also be collected through the water flow pipe for reuse to avoid water waste. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the condensation plate 12 protrudes into the air outlet chamber 4, and the water tank 5 is connected to the condensation plate 12 through a drain pipe 11. The water in the drain pipe 11 will directly inject cold water into the condensation plate 12. A water flow trough is provided on the bottom wall of the air outlet chamber 4. The water flow trough is slightly larger than the upper condensation plate 12 to ensure that the water on the condensation plate 12 will not flow into the air outlet chamber 4. A water flow pipe is provided between the water flow trough and the water tank 5. The water flow pipe can be connected to a water pump to pump the water back to the water tank 5. One end of the square push rod 8 is fixedly connected to the first piston plate 6, and the other end of the square push rod 8 passes through the side wall of the air outlet chamber 4 and is fixedly connected to the extrusion plate 13. The extrusion plate 13 is slightly wider than the condensation plate 12, which can increase the number of contacts between the extrusion plate and it.
[0023] A refrigeration component is installed in the air outlet chamber, and the refrigeration component also includes a piston cylinder 9, a second piston plate 20, an air bag 21, and a circular push rod 7. The piston cylinder 9 is fixedly connected to one side of the air outlet chamber 4 and maintains a certain distance from the air outlet chamber 4. One end of the air bag 21 is fixedly connected to the end of the piston cylinder 9 close to the water tank 5. The end of the air bag 21 away from the water tank 5 is equipped with an air inlet valve and an air outlet valve to facilitate the inflation and deflation of the air bag. The second piston plate 20 is slidably connected to the end away from the air bag 21. A sealing ring is installed on the circumference of the second piston plate 20 close to the inner wall of the piston cylinder 9 to prevent air leakage. A small hole is opened in the baffle at one end of the piston cylinder 9 close to the water tank 4, and a deflation switch is installed on the inner wall close to the water tank 5. One end of the circular push rod 7 is slidably connected to the piston cylinder 9, and a spring is installed between the outer surface of the circular push rod and the piston cylinder 9. Spring, after the airbag 21 is deflated, the circular push rod returns to its original position, and the second rotating shaft 15 is rotatably connected to the air outlet chamber 4. The outer surface of the second rotating shaft 15 is installed with a second fan blade 16 in a circular array. The material of the second fan blade 16 is thin plastic, which ensures the speed of the second rotating shaft 15. One end of the second rotating shaft 15 is fixedly connected to the first rotating rod 17, and the first rotating rod 17 is rotatably connected to the connecting rod 18. The end of the connecting rod 18 away from the first rotating rod 17 is rotatably connected to the second rotating rod 19. The second rotating rod is hinged to the second piston plate 20. A slide groove is provided on the side wall of the air outlet chamber 4, and the square push rod 8 passes through this slide groove. A slider 10 is slidably connected in the slide groove, and the slider 10 is fixedly connected to the square push rod 8. A baffle 14 is fixedly connected to the inner wall of the air outlet chamber 4, and the baffle 14 is placed at 45° to the inner wall of the air outlet chamber 4.
[0024] In the present invention, when in use, the motor drives the first rotating shaft 2 to rotate at a high speed. At this time, the first fan blade 3 on the first rotating shaft 2 draws air into the bellows 1. Since a large amount of air with speed continues to flow into the bellows 1, the air originally in the bellows is continuously accelerated. The accelerated air flows into the air outlet cavity 4. At this time, the air drives the second rotating shaft 15 installed with the second fan blade 16 in the air outlet cavity 4 to rotate. Since the second fan blade 16 is relatively thin, the speed of the second rotating shaft 15 will be faster, and the rotation of the second rotating shaft 15 will be The rod 17 drives the connecting rod 18 to rotate. The connecting rod 18 is located on one side of the end of the second rotating shaft 15. Therefore, one end of the connecting rod 18 will not be affected by the second rotating shaft 15 when it moves in a circular motion with the first rotating rod 17. The connecting rod 18 drives the second rotating rod 19 to rotate. The second rotating rod 19 drives the second piston plate 20 to reciprocate in the piston cylinder 9 and pushes the gas in the piston cylinder 9 into the airbag 21. At this time, a large amount of air flows into the airbag 21 and gradually begins to expand until it starts to push the circular push rod 7 to move toward the water tank 5. When the circular push rod 7 moves to the left end of the piston cylinder 9 near one end of the air bag 21, the circular push rod 7 will trigger the air release valve switch installed at one end of the piston cylinder 9, and the air bag 21 will start to deflate. The spring on the circular push rod 7 will pull the circular push rod 7 back to its original position. When the circular push rod 7 moves in the direction of the water tank 5, it will push the first piston plate 6 to move. At this time, the water in the water tank 5 will be squeezed into the drain pipe, so that the water in the water tank will be injected into the condensation plate 12 through the drain pipe. At the same time, the square push rod 8 connected to the first piston plate 6 starts to slide in the chute. The square push rod 8 extends into the air outlet chamber 4 and moves in the middle. The extrusion plate 13 at one end thereof moves back and forth, squeezing out the heated water on the condensation plate 12. The squeezed water flows into the water flow trough and is collected through the water flow pipe installed in the water flow trough, which is convenient for the recycling of water resources. The baffle 14 installed in the air outlet chamber 4 is arranged at an angle to ensure that the blown wind is guided by the baffle 14 and blown onto the condensation plate 12. At this time, the wind contacts the water on the condensation plate 12, and the water can have a better cooling effect on the blown wind.
