Description

Technical Field

[0001] The invention belongs to the technical field of industrial fans, in particular to a high-efficiency refrigeration industrial fan. Background Art

[0002] High-efficiency refrigeration industrial fans are industrial fans specially designed to provide efficient cooling 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.

[0003] For example, the public patent: CN215333499U is a high-efficiency refrigeration industrial fan, which uses an atomizing nozzle at the bottom of the nozzle and the exhaust function of the turbine to achieve water mist cooling, increase the refrigeration effect, and improve the practicality of the product.

[0004] In the process of transmitting wind, the sprayed water mist can effectively absorb the heat in the air and achieve the effect of air cooling. However, 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. In addition, it may also have adverse effects on the indoor environment, such as deterioration of air quality, and may have a negative impact on human health.

One end of the torsion spring is fixedly connected to the outer wall of the rotating shaft, and the other end is fixedly connected to the inside of the air inlet pipe.

[0013] The rotating rod is hollow, and a water inlet hole is provided on the outer wall of the rotating rod.

At this time, the float slides downward, and the ratchet rod is pulled to rotate by the second pull rope to release the obstruction to the ratchet. The coil spring drives the transmission shaft to rotate counterclockwise, so that the rotating rod reels the water-absorbing sponge, and also makes the first water hole correspond to the second water hole. With the cooperation of the connecting pipe, the interior of the rotating rod is in a negative pressure state, and finally the water in the water-absorbing sponge is further sucked out through the water inlet hole, so as to further reduce the water content of the water-absorbing sponge and ensure the water filtering effect.

DETAILED DESCRIPTION

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

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

[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 mounted 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 transporting the water in the water receiving box 3 to the interior 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 provided filter 4. Then, the filtered air flow is sprayed with water through the provided atomizing nozzle. The water mist is used to filter the smaller dust particles in the air flow. The water mist spraying the air flow can also absorb the heat energy in the air flow, thereby cooling 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 air flow enters the wind cabinet 1, the air flow carrying water mist will pass through the gaps in the water-absorbing sponge 22. The water molecules in the air flow can be absorbed by the water-absorbing sponge 22, so that the air flow entering the wind cabinet 1 carries fewer water molecules, reducing the impact of water vapor on the wind cabinet 1, thereby improving the service life of the wind cabinet 1.

[0042] As a preferred embodiment of the present invention, the water circulation assembly 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 interior 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 interior 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 water-absorbing 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 reeled in, so that the water-absorbing sponge 22 is guaranteed to be in the unfolded state, which can better filter water from the passing air flow. At this time, the water-absorbing sponges 22 on both sides can be reeled in by controlling the rotation of the rotating rod 27, and the water in the water-absorbing sponge 22 can be squeezed out by cooperating with the tension given by the first pull rope 24. By regularly squeezing out the water in the water-absorbing sponge 22, the water filtering effect of the water-absorbing sponge 22 is ensured.

[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 with 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 reels the water-absorbing sponge 22, the water-absorbing sponge 22 will wrap around 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 draws water from the water receiving box 3, it will also draw water from the water-absorbing sponge 22 through the water inlet hole 28. Combined with the squeezing of the water-absorbing sponge 22, the drainage effect of the water-absorbing 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, and a guide groove 33 for the guide block 32 to slide is provided at the bottom end of the rotating rod 27. 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 assembly 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 and the second water hole 35 correspond to each other. 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, there are two rotating rods 27, water-absorbing sponges 22 and rotating blocks 30, which are 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] By means of the two rotating rods 27 and the two water-absorbing sponges 22, when the first group of water-absorbing sponges 22 is squeezing 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 out water, 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 out water, 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 a connecting pipe 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, and 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, it drives the first bevel gear 12 to rotate, and through engagement, it drives the second bevel gear 13 to rotate, and at this time, the transmission rod 14 can rotate.

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

[0059] The ratchet rod 21 is elastically mounted inside the filter 4. The ratchet rod 21 is elastically arranged to keep the ratchet wheel 18 blocked. When the ratchet wheel 18 rotates, the transmission shaft 15 rotates. When the ratchet wheel 18 rotates clockwise, the transmission shaft 15 rotates clockwise. At this time, the coil spring 20 is deformed and stores elastic potential energy. By rotating the ratchet rod 21, the blockage of the ratchet wheel 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, the first bevel gear 12 and the second bevel gear 12 rotate 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. 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 air flow.

[0060] As a preferred embodiment of the present invention, a rotating rod 6 is rotatably installed inside the filter screen 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 card block 26. The inside of the ratchet 18 is provided with a card slot 36 for the card block 26 to engage, and both sides of the card 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 can no longer drive the ratchet 18 to continue rotating. At this time, the inclined surfaces provided on both sides of the block 26 cooperate with the card groove 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.

[0062] As a preferred embodiment of the present invention, a float 17 is provided inside the water receiving box 3 , the top end of the float 17 is fixedly connected to the second pull rope 16 , and the other end of the second pull rope 16 is fixedly connected to the top end 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 drop. 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 the 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, 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. 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 improving 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 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 set filter 4, and then the filtered air flow is sprayed with water through the set atomizing nozzle to wash. The water mist is used to filter the smaller dust particles in the air flow, and the heat energy in the air flow can be absorbed by spraying the air flow with water mist, which can cool the incoming air flow. At this time, the air flow carrying water mist will pass through the gaps in the water-absorbing sponge 22, and the water molecules in the air flow can be absorbed by the water-absorbing sponge 22, so that the air flow entering the wind cabinet 1 carries fewer water molecules, reducing the impact of water vapor on the wind cabinet 1, thereby improving the service life of the wind cabinet 1.

[0066] The airflow enters the air inlet pipe 2 and blows the impeller 5, causing the rotating rod 6 to drive the block 26 to rotate the ratchet 18 clockwise, and under the action of the transmission shaft 15, the coil spring 20 is driven to rotate until the water-absorbing sponge 22 absorbs the water in the water receiving box 3 and the water level is lowered. 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, so that it releases the obstruction to the ratchet 18. At this time, the coil spring 20 releases its elastic potential energy, driving 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. 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.
