[0002] High-efficiency refrigeration industrial fans are industrial fans specially designed to provide efficient refrigeration effects. In specific applications, high-efficiency refrigeration industrial fans can not only effectively reduce indoor temperature and provide a comfortable working environment, but also provide powerful ventilation functions when needed to ensure the freshness and quality of the air.

[0004] In the process of transmitting wind, although the sprayed water mist can effectively absorb the heat in the air and achieve the effect of air cooling, this sprayed water mist will also quickly gather dust particles in the air, pollute the inside of the fan, interfere with the normal operation of the fan, and reduce its efficiency.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1: Figures 1 to 9 As shown, a high-efficiency refrigeration industrial fan according to an embodiment of the present invention comprises a wind cabinet 1 on which an air inlet pipe 2 is arranged.

[0036] A filter screen 4 is provided on the air inlet pipe 2, a water storage box 10 is provided at the top of the inner wall of the air inlet pipe 2, an atomizing nozzle is provided at the bottom of the water storage box 10, a water receiving box 3 is fixedly installed at the bottom of the inner wall of the air inlet pipe 2, a water inlet 11 is provided at the top of the water receiving box 3, and a water circulation component is provided on the air inlet pipe 2 for conveying the water in the water receiving box 3 to the inside of the water storage box 10;

[0037] The sprayed water can flow into the interior of the water receiving box 3 through the water inlet 11 opened on the water receiving box 3.

[0038] When the wind cabinet 1 is started, the air flow will enter the interior of the wind cabinet 1 through the air inlet pipe 2. The dust in the air flow can be filtered through the filter 4, and then the filtered air flow is sprayed with water through the atomizing nozzle. The water mist is used to filter the smaller dust particles in the air flow. The water mist can also absorb the heat energy in the air flow by spraying the air flow, so as to cool the incoming air flow.

[0039] The water circulation component can be set up to recycle the water after spraying, saving water resources to a certain extent.

[0040] A rotating rod 27 is rotatably installed inside the air inlet pipe 2, and water-absorbing sponges 22 are fixedly installed on both sides of the rotating rod 27. A tensioning assembly is provided inside the air inlet pipe 2 to unfold the water-absorbing sponge 22 and fit it against both sides of the inner wall of the air inlet pipe 2.

[0041] The water-absorbing sponge 22 is unfolded by the set tensioning component, and the water-absorbing sponge 22 blocks the inside of the air inlet pipe 2. When the airflow enters the wind cabinet 1, the airflow carrying water mist will pass through the gaps in the water-absorbing sponge 22. The water molecules in the airflow can be absorbed by the water-absorbing sponge 22, so that the airflow entering the wind cabinet 1 carries fewer water molecules, reducing the influence of water vapor on the wind cabinet 1, thereby increasing the service life of the wind cabinet 1.

[0042] As a preferred embodiment of the present invention, the water circulation component includes a water pump 7, a water suction pipe 9 and a water outlet pipe 8. The water pump 7 is fixedly installed at the top of the air inlet pipe 2, one end of the water suction pipe 9 is fixedly connected to the input end of the water pump 7, and the other end of the water suction pipe 9 extends to the inside of the water receiving box 3, one end of the water outlet pipe 8 is fixedly connected to the output end of the water pump 7, and the other end of the water outlet pipe 8 extends to the inside of the water storage box 10.

[0043] By starting the water pump 7, the water in the water receiving box 3 can be sucked out through the water suction pipe 9, and transported to the inside of the water storage box 10 through the water outlet pipe 8, and finally sprayed out through the atomizing nozzle.

[0044] As a preferred embodiment of the present invention, the tensioning assembly includes a rotating shaft 23, a first pull rope 24 and a torsion spring 25. The rotating shaft 23 is fixedly installed inside the air inlet pipe 2, one end of the first pull rope 24 is fixedly connected to the rotating shaft 23, and the other end is fixedly connected to the absorbent sponge 22. One end of the torsion spring 25 is fixedly connected to the outer wall of the rotating shaft 23, and the other end is fixedly connected to the inside of the air inlet pipe 2.

[0045] By setting the torsion spring 25, the rotating shaft 23 can always keep the first pull rope 24 rolled up, so that the water-absorbing sponge 22 can be guaranteed to be in the unfolded state, and the water passing through the airflow can be better filtered. At this time, the rotation of the rotating rod 27 can be controlled to roll up the water-absorbing sponges 22 on both sides, and the pulling force given by the first pull rope 24 can be used to squeeze out the water in the water-absorbing sponge 22. By regularly squeezing out the water in the water-absorbing sponge 22, the water filtering effect of the water-absorbing sponge 22 is guaranteed.

[0046] As a preferred embodiment of the present invention, the rotating rod 27 is hollow, and a water inlet hole 28 is provided on the outer wall of the rotating rod 27. A rotating block 30 is rotatably installed at the bottom end of the rotating rod 27, and a connecting chamber 31 is provided inside the rotating block 30. A first water hole 34 is provided at the bottom end of the rotating rod 27, and a second water hole 35 is provided at the top end of the rotating block 30. The connecting chamber 31 is connected to the water suction pipe 9 through the connecting pipe 29.

[0047] After the second water hole 35 is driven to rotate by the rotating block 30 and is aligned with the first water hole 34, the inner cavity of the rotating rod 27 will be connected to the connecting chamber 31 through the first water hole 34 and the second water hole 35. Since the connecting chamber 31 is connected to the water suction pipe 9 through the connecting pipe 29, when the water suction pipe 9 absorbs water, as long as the rotating block 30 is connected with the inner cavity of the rotating rod 27, the inner cavity of the rotating rod 27 will be under negative pressure under the action of the connecting pipe 29, and the water inlet hole 28 will also be under negative pressure.

[0048] When the rotating rod 27 rolls up the absorbent sponge 22, the absorbent sponge 22 will wrap the water inlet hole 28, connecting the rotating block 30 with the inner cavity of the rotating rod 27. When the water absorption pipe 9 extracts water from the water receiving box 3, it will also extract the water in the absorbent sponge 22 through the water inlet hole 28. Combined with the squeezing of the absorbent sponge 22, the drainage effect of the absorbent sponge 22 can be further improved.

[0049] As a preferred embodiment of the present invention, a guide block 32 is fixedly installed on the top of the rotating block 30, a guide groove 33 for the guide block 32 to slide is provided at the bottom end of the rotating rod 27, and a transmission rod 14 is rotatably installed inside the air inlet pipe 2, and the transmission rod 14 is connected to the rotating block 30 through a first transmission assembly.

[0050] By cooperating with the guide block 32 and the guide groove 33, the rotation angle between the rotating block 30 and the rotating rod 27 can be limited. When the rotating block 30 drives the guide block 32 to slide from one end of the guide groove 33 to the other end, the correspondence and separation of the first water hole 34 and the second water hole 35 can be achieved.

[0051] The first transmission component can be a common pulley transmission. When the transmission rod 14 rotates, it will drive the rotating block 30 to rotate. Since the length of the guide groove 33 is limited, when the guide block 32 slides to the end of the guide groove 33, the continuous rotation of the rotating block 30 will drive the rotating rod 27 to rotate synchronously. The rotating block 30 drives the guide block 32 to rotate, so that the first water hole 34 corresponds to the second water hole 35. As the rotating block 30 drives the rotating rod 27 to continuously reel in the water-absorbing sponge 22, not only can the water in the water-absorbing sponge 22 be squeezed out, but also the negative pressure given by the water absorption pipe 9 can be used to make the water in the water-absorbing sponge 22 be sucked out by the water inlet hole 28, thereby reducing the water content of the water-absorbing sponge 22, thereby improving the water filtering effect of the water-absorbing sponge 22.

[0052] As a preferred embodiment of the present invention, two rotating rods 27, water-absorbing sponges 22 and rotating blocks 30 are provided and symmetrically arranged. The two rotating blocks 30 are connected by a second transmission assembly, and the connecting chambers 31 opened inside the two rotating blocks 30 are connected.

[0053] Through the two rotating rods 27 and the two water-absorbing sponges 22, when the first group of water-absorbing sponges 22 squeeze water, the second group of water-absorbing sponges 22 can still filter the moisture in the airflow, which can effectively ensure the squeezing work of the water-absorbing sponges 22 without stopping the machine.

[0054] The movement trajectories of the two groups of water-absorbing sponges 22 are opposite. When the first group of water-absorbing sponges 22 is rolled up and squeezed, the second group of water-absorbing sponges 22 is in an unfolded state. When the second group of water-absorbing sponges 22 is rolled up and squeezed, the first group of water-absorbing sponges 22 is in an unfolded state.

[0055] The second transmission assembly can also be a pulley drive. Both sets of rotating blocks 30 are provided with connecting pipes 29 , and the rear connecting pipe 29 is connected to the front connecting pipe 29 .

[0056] As a preferred embodiment of the present invention, a transmission shaft 15 is rotatably installed inside the air inlet pipe 2, a first bevel gear 12 is fixedly installed on one end of the transmission shaft 15 close to the transmission rod 14, a second bevel gear 13 is fixedly installed on the top of the transmission rod 14, and the first bevel gear 12 is meshed with the second bevel gear 13.

[0057] When the transmission shaft 15 rotates, the first bevel gear 12 is driven to rotate, and the second bevel gear 13 is driven to rotate through meshing, and the transmission rod 14 can rotate at this time.

[0058] As a preferred embodiment of the present invention, a ratchet 18 is rotatably installed inside the filter screen 4, a ratchet rod 21 for blocking the ratchet 18 is rotatably installed inside the filter screen 4, the side wall of the ratchet 18 is fixedly connected to the transmission shaft 15, and a mounting shell 19 is fixedly installed on the side wall of the filter screen 4, and a coil spring 20 is arranged between the mounting shell 19 and the transmission shaft 15.

[0059] The ratchet rod 21 is elastically installed inside the filter 4. The ratchet rod 21 can keep blocking the ratchet 18 through the elastic setting. When the ratchet 18 rotates, it drives the transmission shaft 15 to rotate. When the ratchet 18 rotates clockwise, it drives the transmission shaft 15 to rotate clockwise. At this time, the coil spring 20 will deform and store elastic potential energy. By rotating the ratchet rod 21, the blocking of the ratchet 18 is released, and the coil spring 20 releases the elastic potential energy, driving the transmission shaft 15 to rotate counterclockwise. At the same time, through the first bevel gear 12 and the second bevel gear 12, the transmission shaft 15 is rotated counterclockwise. With the cooperation of the bevel gear 13, the transmission rod 14 is controlled to rotate counterclockwise, and the first rotating block 30 is rotated counterclockwise through the first transmission assembly, which not only causes the rotating rod 27 to reel in the water-absorbing sponge 22, but also causes the first water hole 34 to correspond to the second water hole 35, and with the cooperation of the connecting pipe 29, the interior of the rotating rod 27 is made to be in a negative pressure state, and finally the water in the water-absorbing sponge 22 is further sucked out through the water inlet hole 28, thereby further reducing the water content of the water-absorbing sponge 22 and improving the filtering effect of the water in the airflow.

[0060] As a preferred embodiment of the present invention, a rotating rod 6 is rotatably installed inside the filter 4, and an impeller 5 is fixedly installed on the outer wall of the rotating rod 6. One end of the rotating rod 6 extends to the inside of the ratchet 18 and is elastically installed with a block 26. The ratchet 18 is provided with a slot 36 for the block 26 to engage, and both sides of the block 26 are inclined.

[0061] When the air flow enters the air inlet pipe 2, it will blow the impeller 5, causing the rotating rod 6 to drive the block 26 to rotate clockwise inside the ratchet 18. A pressure spring is provided between the block 26 and the rotating rod 6. When the rotating rod 6 rotates clockwise, the ratchet 18 is driven to rotate clockwise through the block 26. Under the action of the transmission shaft 15, the coil spring 20 is driven to rotate, causing the coil spring 20 to deform and store elastic potential energy. As the coil spring 20 continues to deform, the potential energy continues to increase until it is greater than the potential energy of the pressure spring. At this time, the rotating rod 6 drives the block 26 to rotate again, and cannot drive the ratchet 18 to continue rotating. At this time, the inclined surfaces set on both sides of the block 26 cooperate with the card slot 36, and the block 26 will be pushed into the interior of the rotating rod 6, and the rotation of the rotating rod 6 will not be blocked at this time.

[0062] As a preferred embodiment of the present invention, a floating block 17 is provided inside the water receiving box 3 , a second pull rope 16 is fixedly connected to the top of the floating block 17 , and the other end of the second pull rope 16 is fixedly connected to the top of the ratchet rod 21 .

[0063] The float 17 can slide inside the water receiving box 3 by buoyancy. When most of the water inside the water receiving box 3 is absorbed by the water-absorbing sponge 22, the water level inside the water receiving box 3 will be lowered. At this time, the float 17 will also slide downward inside the water receiving box 3. Through the setting of the second pull rope 16, the ratchet rod 21 can be pulled to rotate, so that it releases the obstruction of the ratchet wheel 18. At this time, the coil spring 20 releases its elastic potential energy, driving the transmission shaft 15 to rotate counterclockwise. At the same time, through the cooperation of the first bevel gear 12 and the second bevel gear 13, the transmission rod 14 is controlled to rotate counterclockwise. The rotating block 30 is rotated counterclockwise through the first transmission assembly, which not only makes the rotating rod 27 reel in the water-absorbing sponge 22, but also makes the first water hole 34 correspond to the second water hole 35, and with the cooperation of the connecting pipe 29, the interior of the rotating rod 27 is in a negative pressure state, and finally the water in the water-absorbing sponge 22 is further sucked out through the water inlet hole 28, so as to further reduce the water content of the water-absorbing sponge 22 and improve the filtering effect of water in the air flow.

[0064] After the water level rises, the floating block 17 slides upward, causing the ratchet rod 21 to block the ratchet wheel 18 again.

[0065] Working principle: When the wind cabinet 1 is started, the airflow will enter the interior of the wind cabinet 1 through the air inlet pipe 2. The dust in the airflow can be filtered through the filter net 4, and then the filtered airflow is sprayed with water through the atomizing nozzle. The smaller dust particles in the airflow are filtered by the water mist, and the heat energy in the airflow can be absorbed by spraying the airflow with water mist, so that the incoming airflow can be cooled. At this time, the airflow carrying water mist will pass through the gaps in the water-absorbing sponge 22, and the water molecules in the airflow can be absorbed by the water-absorbing sponge 22, so that the airflow entering the wind cabinet 1 carries fewer water molecules, reducing the influence of water vapor on the wind cabinet 1, thereby increasing the service life of the wind cabinet 1.

[0066] The airflow enters the air inlet pipe 2 and blows the impeller 5, so that the rotating rod 6 drives the card block 26 to rotate the ratchet 18 clockwise, and the coil spring 20 is driven to rotate under the action of the transmission shaft 15, until the water-absorbing sponge 22 absorbs the water in the water receiving box 3 to lower the water level. At this time, the floating block 17 will also slide downward inside the water receiving box 3. Through the setting of the second pull rope 16, the ratchet rod 21 can be pulled to rotate to release the obstruction to the ratchet 18. At this time, the coil spring 20 releases its elastic potential energy, drives the transmission shaft 15 to rotate counterclockwise, and at the same time, With the cooperation of the first bevel gear 12 and the second bevel gear 13, the transmission rod 14 is controlled to rotate counterclockwise, and the rotating block 30 is rotated counterclockwise through the first transmission assembly, which not only causes the rotating rod 27 to reel in the water-absorbing sponge 22, but also causes the first water hole 34 to correspond to the second water hole 35, and with the cooperation of the connecting pipe 29, the interior of the rotating rod 27 is in a negative pressure state, and finally the water in the water-absorbing sponge 22 is further sucked out through the water inlet hole 28, thereby further reducing the water content of the water-absorbing sponge 22 and ensuring the water filtering effect.
