[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used herein in the specification of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0056] As Figures 1 to 9 shown, the present application proposes a dust removal and cooling dust removal fan, which comprises a main body assembly 100, the main body assembly 100 comprising a driving motor 101, a fan blade shell 103, an air inlet pipe 104 and an air outlet pipe 105, the driving motor 101 being used to drive the rotation of the fan blade in the fan blade shell 103, the air inlet pipe 104 and the air outlet pipe 105 being fixed on the air inlet and the air outlet of the fan blade shell 103 respectively, the external air being sucked into the fan blade shell 103 from the air inlet pipe 104 and being discharged from the air outlet pipe 105; further comprising a cooling assembly 200; the cooling assembly 200 comprising a ventilation pipe 201, a baffle 204, a connecting pipe 205, a collecting groove 206, a water suction head 207, a spray head 208, a water delivery pipe 209 and a copper pipe 2041;

[0057] The printing and dyeing factory produces high-temperature gas in the drying process to increase the air temperature. The high-temperature air enters the fan shell 103 through the air inlet pipe 104. A plurality of baffles 204 are fixed in the air inlet pipe 104. The air entering from the air inlet pipe 104 contacts the baffles 204. The copper pipes 2041 are fixed on the two side walls of the baffles 204 and are continuously bent into S-shaped. One end of the copper pipes 2041 is communicated with the water storage tank 202 through the connecting pipe 205. The cold water stored in the water storage tank 202 enters the copper pipes 2041 through the connecting pipe 205 by the water pump. The other end of the copper pipes 2041 is communicated with the temporary storage tank 203 through the connecting pipe 205. The air entering the air inlet pipe 104 contacts the copper pipes 2041. The heat in the air is absorbed by the water flowing in the copper pipes 2041, so that the temperature of the air entering the fan shell 103 is reduced. The warm water flowing out of the copper pipes 2041 is temporarily stored in the temporary storage tank 203.

[0058] The ventilation pipe 201 is fixed on the side wall of the air outlet pipe 105. The ventilation pipe 201 and the air outlet pipe 105 are communicated. The air outlet of the ventilation pipe 201 faces the surface of the driving motor 101. Part of the air blown out of the air outlet pipe 105 is blown to the surface of the driving motor 101 through the ventilation pipe 201. The collecting groove 206 is fixed on the inner side wall of the air outlet pipe 105. The top of the air outlet pipe 105 is connected with the pipeline for conveying air. The water droplets attached to the air outlet pipe 105 and the pipeline for conveying air slide along the side wall of the air outlet pipe 105 and fall into the collecting groove 206. The collecting groove 206 is used for collecting the water droplets attached to the inner side wall of the air outlet pipe 105. The water outlet of the water delivery pipe 209 is located at the air outlet of the ventilation pipe 201. The water suction head 207 is fixed on the water delivery pipe 209. The water collected in the collecting groove 206 is delivered to the water suction head 207 through the water delivery pipe 209. The water suction head 207 is located at the air outlet of the ventilation pipe 201. The water suction head 207 can store the collected water. The water on the water suction head 207 is blown to the driving motor 101 in the form of small water droplets by the air blown out of the air outlet of the ventilation pipe 201, and the water droplets are gasified. The water droplets absorb the heat in the air in the process of gasification.

[0059] Preferably, the number of the spray heads 208 in the air outlet pipe 105 is 12 to 18.

[0060] Preferably, the waterproof level of the driving motor 101 is IPX6.

[0061] Preferably, the collecting groove 206 is a rectangular ring with a groove on the upper side, and the collecting groove 206 is attached to the side wall of the air outlet pipe 105. The air entering the air outlet pipe 105 is mixed with the water mist sprayed by the spray head 208. The water mist will condense into water droplets after contacting the side wall of the air outlet pipe 105. The condensed water droplets flow along the inner side wall of the air outlet pipe 105 and fall into the groove on the collecting groove 206. The water delivery pipe 209 is fixed at the bottom of the collecting groove 206. The water delivery pipe 209 is in communication with the inside of the groove on the upper side of the collecting groove 206. The bottom of the groove on the collecting groove 206 is an inclined surface, which is lowest at the connection with the water delivery pipe 209, so that the water entering the groove can flow into the water delivery pipe 209.

[0062] Preferably, the connecting pipe 205 is a copper metal pipe.

[0063] Preferably, as shown in Figure 6 The water absorption head 207 includes a water storage ring 2071, a fixed ring 2072, a connecting rod 2073, and a water absorption brush 2074.

The control valve 210 can control the amount of water delivered to the water absorption head 207 by the water delivery pipe 209. The end of the water delivery pipe 209 is provided with a water outlet. The water storage ring 2071 is a circular ring, which is fixed to the end of the connecting rod 2073 and is fixed to the water delivery pipe 209 through the connecting rod 2073. A plurality of annular grooves are formed in the water storage ring 2071, which are in communication with each other. A groove for water flow is formed in the connecting rod 2073. The water in the water delivery pipe 209 flows out of the water outlet and flows into the grooves in the water storage ring 2071 through the groove in the connecting rod 2073, and flows in the grooves in the water storage ring 2071 by capillary effect. A plurality of fixed rings 2072 are fixed to the water storage ring 2071. The fixed rings 2072 are circular rings with water guiding property. The water in the water storage ring 2071 flows to the fixed rings 2072 by capillary effect. The water absorption brush 2074 is fixed outside the fixed rings 2072. The water flowing to the fixed rings 2072 can be stored in the gaps between the water absorption brushes 2074 by capillary effect. The airflow blown by the fan blows off the water stored between the water absorption brushes 2074.

[0064] Preferably, the water pump located in the temporary storage box 203 is a high-pressure water pump, which can make the water sprayed by the spray head 208 form a small water mist. The temperature of the water mist sprayed by the spray head 208 is between 50℃ and 60℃, which can make the water mist suspended in the air for a longer time, thereby improving the dust capturing effect of the water mist.

[0065] Preferably, the fixing ring 2072 is a hollow rubber ring, the inside of the fixing ring 2072 is filled with cotton yarn, a plurality of annular grooves are formed on the fixing ring 2072, the cotton yarn inside the fixing ring 2072 extends into the grooves on the water storage ring 2071, the water on the water storage ring 2071 flows to the fixing ring 2072 by capillary effect, and the cotton yarn filled in the inside of the fixing ring 2072 stores the water; a plurality of round holes are formed on the fixing ring 2072, the water absorbing brush 2074 is fixed in the round holes, the part of the water absorbing brush 2074 located in the fixing ring 2072 is in contact with the cotton yarn, and the water stored in the cotton yarn in the fixing ring 2072 flows to the bristles of the water absorbing brush 2074 by capillary effect.

[0066] Preferably, the bristles of the water absorbing brush 2074 are made of natural fiber material, water is adsorbed on the bristles by capillary effect, and the gaps between the bristles can temporarily store water.

[0067] Preferably, the material of the bristles of the water absorbing brush 2074 is coconut fiber.

[0068] Preferably, the top of the water storage tank 202 is fixed with a support frame 102, the support frame 102 is used for fixing the driving motor 101, the rotating shaft of the driving motor 101 extends into the fan blade shell 103, the fan blade is fixed at the end of the rotating shaft of the driving motor 101, the fan blade is located in the fan blade shell 103, the upper side of the water storage tank 202 is fixed with a fixing frame 106, the fan blade shell 103 is fixed on the water storage tank 202 by the fixing frame 106, the water storage tank 202 stores tap water for cooling the air entering the fan, and the temperature of the tap water is between 15℃ and 20℃.

[0069] The dust removal and cooling fan of the embodiment of the application has the following advantages in actual use:

[0070] The fan rotates under the drive of the driving motor 101, so that the high-temperature air from the air inlet pipe 104 enters the fan shell 103. The water pump sends the cold water in the water storage tank 202 to the copper pipe 2041 in the air inlet pipe 104. The high-temperature air in the air inlet pipe 104 contacts the copper pipe 2041, the water flowing in the copper pipe 2041 carries away the heat in the air, and the temperature of the water in the copper pipe 2041 rises. The warm water flowing out of the copper pipe 2041 is stored in the temporary storage tank 203. The water pump drives the warm water in the temporary storage tank 203 to be sprayed into the air outlet pipe 105 from the spray head 208 to form water mist. The air blown out of the air outlet pipe 105 blows the water mist into the air, and the water mist floating in the air wets the dust suspended in the air. The water mist sprayed from the air outlet pipe 105 is partially attached to the air outlet pipe 105 and the ventilation pipe 201 to form water droplets. The water droplets are collected by the collecting groove 206, and the water is transported to the water suction head 207 through the water conveying pipe 209. The air blown out of the fan is partially blown to the surface of the motor from the ventilation pipe 201, and the water stored on the water suction head 207 is blown to the surface of the motor in the form of small water droplets. The blown water droplets vaporize to reduce the temperature of the air, thereby absorbing the heat emitted by the driving motor 101, realizing local cooling of the surface of the motor during the operation of the fan, avoiding accumulation of heat to increase the temperature of the motor, and eliminating the dust floating in the air.

[0071] Example two: considering that the printing and dyeing plant will generate a large amount of dust during the drying process of the fabric, part of the dust will float in the air. The dust floating in the air will adhere to the surface of the driving motor 101, and the water consumption during the fabric production process is large, so that the air humidity is large, which causes water droplets to condense on the surface of the driving motor 101. The mixture of dust and water droplets adhering to the surface of the driving motor 101 will form dirt. The dirt adhering to the surface of the driving motor 101 will affect the heat dissipation effect of the driving motor 101, and the dirt adhering to the gap of the driving motor 101 is difficult to clean. Therefore, in view of the above problems, further improvement is made, specifically as follows:

[0072] As Figures 10 to 17As shown, the sidewall of the ventilation pipe 201 is provided with a rectangular opening, and the gas delivery pipe 211 is fixed on the rectangular opening of the sidewall of the ventilation pipe 201. The gas delivery pipe 211 is in communication with the inside of the ventilation pipe 201, and the airflow entering the ventilation pipe 201 is delivered to the surface of the driving motor 101 through the gas delivery pipe 211. The gas delivery pipe 211 is a bent rectangular pipe, the water suction head 207 is fixed on the end of the gas delivery pipe 211, and the inside of the water suction head 207 is provided with an annular channel in communication with the gas delivery pipe 211. The airflow blown out of the gas delivery pipe 211 enters the annular channel in the inside of the water suction head 207. The water delivery pipe 209 is fixed on the water suction head 207, and the water collected in the collecting groove 206 is delivered to the inside of the water suction head 207 through the water delivery pipe 209. The sidewall of the water suction head 207 is parallel to the end surface of the driving motor 101, and the side of the water suction head 207 facing the driving motor 101 is provided with an air outlet. The water delivered into the water suction head 207 through the water delivery pipe 209 is blown out of the air outlet of the water suction head 207 under the action of the airflow delivered by the gas delivery pipe 211. The blown airflow flows along the axial direction of the driving motor 101 and is blown towards the sidewall of the driving motor 101. The airflow flows along the direction of the heat dissipation fins on the surface of the driving motor 101, and the dust attached to the heat dissipation fins of the driving motor 101 is blown off in the process of airflow. The blown airflow can also make the water droplets mixed in the airflow vaporize on the surface of the driving motor 101, thereby absorbing the heat generated by the driving motor 101.

[0073] Preferably, as shown in Figure 17 As shown, the water suction head 207 is a circular ring, and the rotating shaft of the driving motor 101 passes through the middle of the water suction head 207. The water spraying pipes 2075 are distributed around the driving motor 101, and a gap is left between the water spraying pipes 2075 and the driving motor 101. The diameter of the central hole of the water suction head 207 is greater than the diameter of the driving motor 101, so that the airflow blown out of the water spraying pipes 2075 flows along the sidewall of the driving motor 101.

[0074] Preferably, as shown in Figure 12 As shown, the sidewall of the water suction head 207 facing the driving motor 101 is fixed with a plurality of water spraying pipes 2075, and the water suction head 207 is provided with an annular cavity in communication with the water delivery pipe 209. The water delivery pipe 209 is in communication with the water spraying pipes 2075 through the annular cavity, and the water in the water delivery pipe 209 flows into the water spraying pipes 2075 through the annular cavity. The water spraying pipes 2075 are in communication with the gas delivery pipe 211 through the annular channel in the water suction head 207, and the airflow blown out of the gas delivery pipe 211 can be blown towards the driving motor 101 from the water spraying pipes 2075. The water spraying pipes 2075 are fixed with driving fans 213, and the driving fans 213 are driven by brushless motors. The driving fans 213 are used to increase the flow speed of the air in the water spraying pipes 2075, so that the water droplets blown out of the water spraying pipes 2075 can be refined into smaller water mist. The water mist can vaporize faster in the air, and the blown airflow can blow out the dust attached to the gaps of the heat dissipation fins of the driving motor 101.

[0075] Preferably, the water absorption head 207 is fixed with 8 to 12 water spraying pipes 2075.

A plurality of partitions 2042 are fixed on the two sidewalls of the baffle 204, and the partitions 2042 are located between the copper pipes 2041 and can contact the air entering the air inlet pipe 104 to absorb the heat carried by the high-temperature air entering the air inlet pipe 104. The partitions 2042 contact the copper pipes 2041, and the heat absorbed by the partitions 2042 is transferred to the copper pipes 2041, and the heat is carried away by the water flowing in the copper pipes 2041.

[0077] Preferably, the partition 2042 is a copper plate, which can transfer the heat in the air to the copper plate.

[0078] Preferably, the driving fan 213 is driven by a brushless motor, and each water spraying pipe 2075 is fixed with a driving fan 213.

[0079] Preferably, as shown in Figure 9 The copper pipes 2041 on the baffle 204 are connected to each other, and each copper pipe 2041 is fixed with a connecting head 2043 at both ends, which is used to fix the connecting pipe 205 on the copper pipe 2041. Each copper pipe 2041 on the baffle 204 is connected through the connecting pipe 205, so that the water in the water storage tank 202 can flow through each copper pipe 2041 on the baffle 204, and the water flowing in the copper pipe 2041 carries away the heat absorbed from the air.

[0080] In actual use, on the basis of the above embodiment, under the driving of the driving motor 101, part of the air entering the air outlet pipe 105 enters the air conveying pipe 211 through the ventilation pipe 201, the air in the air conveying pipe 211 enters the annular channel inside the water suction head 207, the water spraying pipe 2075 and the annular channel inside the water suction head 207 are communicated, so that the air entering the water suction head 207 is blown from the water spraying pipe 2075 to the surface of the driving motor 101, the axis of the water spraying pipe 2075 is parallel to the axis of the driving motor 101, so that the air blown by the water spraying pipe 2075 flows along the axis of the driving motor 101, blows off the dust attached to the surface of the driving motor 101, avoids the dust from being attached to the surface of the driving motor 101 to form dirt, at the same time, the air blown from the water spraying pipe 2075 can blow out the water conveyed by the water conveying pipe 209 into the water spraying pipe 2075, under the action of the driving fan 213, the water droplets are blown into fine water droplets, the water droplets absorb the heat emitted by the driving motor 101, and the driving fan 213 can also accelerate the flow speed of the air blown by the water spraying pipe 2075, blows off the dirt attached to the gap of the heat dissipation fin of the driving motor 101, realizes the cooling of the motor, and cleans the dirt mixed with the water droplets attached to the surface of the motor between the heat dissipation fins.

[0081] Embodiment three: considering that the high temperature generated in the drying process of the printing and dyeing plant will increase the environmental temperature, the fan needs to operate in a high temperature environment for a long time, and the high temperature environment will reduce the heat dissipation efficiency of the fan blade shell 103, so that the heat generated during the operation of the fan blade accumulates in the fan blade shell 103 and cannot be discharged in time, the fan blade of the fan will be overheated and expand, thereby causing vibration and noise, and aggravating the wear of the bearing; therefore, in view of the above problems, further improvement is made, specifically:

The air delivery pipe 211 is located on the upper side of the fan shell 103, and a gap is left between the air delivery pipe 211 and the fan shell 103. The air entering the air delivery pipe 211 from the air vent pipe 201 is blown to the fan shell 103 from the rectangular openings at the bottom of the air delivery pipe 211. The bottom of the air delivery pipe 211 is fixed with a water storage plate 215. The water storage plate 215 is a rectangular plate with a groove on the upper side. The water storage plate 215 stores water delivered by the water delivery pipe 209. The water delivery pipe 209 is fixed with a plurality of connecting pipes 205. The connecting pipes 205 make the water in the water delivery pipe 209 flow to the water storage plate 215. The width of the water storage plate 215 is smaller than the width of the rectangular opening at the bottom of the air delivery pipe 211. A gap is left between the water storage plate 215 and the air delivery pipe 211. The water storage plate 215 is fixed with a plurality of water absorbing brushes 2074 on both sides. The water absorbing brushes 2074 are located in the gap between the water storage plate 215 and the air delivery pipe 211. The water absorbing brushes 2074 are in communication with the groove on the water storage plate 215. The water in the water storage plate 215 can be stored in the gap between the bristles of the water absorbing brushes 2074. When the air is blown out from the rectangular openings at the bottom of the air delivery pipe 211, the water on the water absorbing brushes 2074 is blown off and gasified by the airflow. The heat inside the fan shell 103 is absorbed and dissipated through the fan shell 103, thereby avoiding the accumulation of heat in the fan shell 103, which can cause the temperature of the fan to be too high.

[0083] Preferably, the bottom of the collecting groove 206 is connected with two water delivery pipes 209. One of the water delivery pipes 209 delivers the water collected by the collecting groove 206 to the water absorbing head 207. The other water delivery pipe 209 delivers the water collected by the collecting groove 206 to the water storage plate 215 through the connecting pipe 205.

[0084] Preferably, the roots of the water absorbing brushes 2074 are made of cotton fibers. The material of the bristles of the water absorbing brushes 2074 is the same as that in the first embodiment, which is a natural fiber material.

[0085] Preferably, the water delivery pipe 209 is a copper metal pipe. The diameter of the water delivery pipe 209 connected to the water storage plate 215 is smaller than that of the water delivery pipe 209 connected to the water absorbing head 207.

[0086] Preferably, the bottom of the air delivery pipe 211 is provided with 6 to 8 rectangular openings. Each rectangular opening is fixed with a water storage plate 215.

[0087] In actual use, on the basis of the above embodiment, the air entering the air conveying pipe 211 from the ventilation pipe 201, part of which is delivered into the water suction head 207, and the other part is blown to the surface of the fan blade shell 103 through the rectangular opening at the bottom of the air conveying pipe 211. The water collecting groove 206 collects water, part of which is delivered into the water suction head 207 through the water conveying pipe 209, and the other part is stored on the water storage plate 215. The water storage plate 215 is fixed on both sides of the rectangular opening at the bottom of the air conveying pipe 211, and a gap is left between the water storage plate 215 and the air conveying pipe 211. The water suction brush 2074 is fixed on both sides of the water storage plate 215. The water stored in the water storage plate 215 flows to the water suction brush 2074 by capillary effect. Under the action of the wind generated by the fan, the water droplets adsorbed on the water suction brush 2074 are blown to the surface of the fan blade shell 103. The water droplets evaporate in the process of falling, and absorb the heat on the surface of the fan blade shell 103. The heat generated by the fan can be discharged through the fan blade shell 103, avoiding the accumulation of heat in the fan blade shell 103 and affecting the normal operation of the fan blade. The fan blade shell 103 is cooled when the fan is running, avoiding the accumulation of heat generated by the fan in the fan blade shell 103.
