[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0026] Reference Figures 1 to 6As shown, a strip steel water spraying device of the utility model comprises a strip steel sprayer 11 and an L-shaped support plate 12 fixedly installed at the bottom edge position of one side of the strip steel sprayer 11, a strip steel plate 13 movably sleeved on the inner wall surface of the strip steel sprayer 11, a support column 14 fixedly installed at the edge position of one side of the top of the strip steel sprayer 11, a spray pipe 112 is fixedly installed on the inner wall surface of the strip steel sprayer 11 and at the top edge position of the strip steel plate 13, a direct current pipe 113 is fixedly installed on the top surface of the strip steel sprayer 11, a lap sleeve 114 is fixedly connected to the top surface of the direct current pipe 113, a cold liquid concentration box 116 is fixedly installed on one side surface of the strip steel sprayer 11 and at the edge position of one side of the support column 14, a hot steam counter-mixing unit is fixedly installed on the top outer surface of the support column 14, and the hot steam counter-mixing unit comprises a condensing tank 141 fixedly connected to the top surface of the support column 14, a condensing tank 142 is fixedly connected to the top surface of the support column 14, and a condensing tank 143 is fixedly connected to the top surface of the support column 14. A sealed rotating disk 143 is movably connected to the inner wall surfaces of both sides of the tank 141, a motor 146 arranged on the surface of one side of the sealed rotating disk 143 is fixedly installed on the surface of one side of the strip steel sprayer 11, and a hollow tube a1 movably connected to the inner wall surface of the condensation tank 141 is fixedly connected to the output end of the motor 146, and a guide fan blade 144 is fixedly connected to the inner wall surfaces of the two sealed rotating disks 143 and on the outer surface of the hollow tube a1, a water collecting cylinder 142 is fixedly connected to the bottom surface of the condensation tank 141 and at a middle position, a return pipe 147 is fixedly connected to the top surface of the condensation tank 141 and at a middle position, an air guide pipe 148 is fixedly connected to the top surface of the condensation tank 141 and at the edge positions on both sides, a cooling condensation rod a4 is fixedly connected to the outer surface of the hollow tube a1 and at a middle position between the two one-way honeycomb disks 145, and a circulation guide pipe a3 is provided on the surface of one side of the cold liquid concentration box 116.
[0027] During operation, the spray pipe 112 is used to spray cold water onto the top surface of the strip steel plate 13. When the cold water contacts the surface of the strip steel plate 13, the cold water will evaporate due to the high temperature on the surface of the strip steel plate 13. When the cold water on the surface of the strip steel plate 13 evaporates, the steam generated will accumulate inside the strip steel sprayer 11. At the same time, the motor 146 is used to rotate the hollow tube a1 and the sealing rotating disk 143 at the same time, thereby driving the guide blades 144 on the outer surface of the sealing rotating disk 143 to rotate. The arc shape on the surface of the guide blades 144 is used to drive the gas around the guide blades 144 to concentrate toward the middle position of the condensation tank 141 when the guide blades 144 rotate. As the gas on the inner wall surfaces at both ends of the condensation tank 141 continues to decrease, the gas inside the condensation tank 141 will drive the gas to accumulate. The hot steam accumulated in the strip steel shower 11 flows, and the flowing hot steam passes through the direct current pipe 113, the overlapping casing 114 and the air guide pipe 148 into the interior of the condenser 141. The hot steam concentrated in the middle part of the condenser 141 will gradually cool and liquefy. The liquefied liquid will drip to the inside of the condenser 141 due to its own gravity and slide into the inside of the water collecting cylinder 142 to collect the liquid, so as to achieve the effect of using the guide blade 144 to cause gas flow under the rotation, and then transport and guide the hot steam accumulated in the strip steel shower 11, so as to avoid the hot steam in the strip steel shower 11 from accumulating in the strip steel shower 11. When the hot steam accumulates to a certain extent, the hot steam will leak out from the openings at both ends of the strip steel shower 11, thereby polluting the outside air.
[0028] When the hot steam in the middle of the condensation tank 141 is liquefied, the dripping water source will be concentrated in the water collecting tube 142, and at the same time, the low-temperature water source in the water collecting tube 142 will be injected into the cold liquid concentration tank 116 in cooperation with the guide tube on the outer surface of the water collecting tube 142, and at the same time, the cold water in the cold liquid concentration tank 116 that has been cooled will be injected into the hollow tube a1 in cooperation with the circulation guide tube a3. When the low-temperature water source circulates in the hollow tube a1, the low-temperature water source will quickly cool down the surface of the hollow tube a1 and the cooling condensation rod a4. The cooled hollow tube a1 and the cooling condensation rod a4 will contact the hot steam in the condensation tank 141, and the temperature difference will be used to make the hot gas and the low-temperature gas exchange heat quickly, thereby quickly absorbing the high temperature inside the hot steam. At the same time, the motor 146 will cooperate with the motor 146 to The rotation of the hollow tube a1 and the cooling condensation rod a4 increases the stirring and mixing of the cooling condensation rod a4 and the hot steam inside the condensation tank 141, thereby contacting the hot steam at different positions inside the condensation tank 141. The water droplets condensed on the surface of the cooling condensation rod a4 are thrown onto the inner wall of the condensation tank 141 under the centrifugal shaking of the cooling condensation rod a4, and then the water droplets slide downward through the curvature of the inner wall of the condensation tank 141. The water source gathered at the bottom of the inner side of the condensation tank 141 will enter the water collecting tube 142 to collect the water source, thereby achieving the effect of swinging the hollow tube a1 and the cooling condensation rod a4 by the motor 146, thereby increasing the mixing and contact of the cooling condensation rod a4 with the hot steam inside the condensation tank 141, thereby increasing the contact range and area between the cooling condensation rod a4 and the hot steam.
[0029] When the guide blades 144 are rotating, the hot steam inside the condensation tank 141 will be concentrated in the middle part of the condensation tank 141. As the hot steam in the middle part of the condensation tank 141 continues to accumulate, some hot steam that has not yet been liquefied but has been cooled will pass through the return pipe 147 into the interior of the overlap shell 114, and mix with some hot steam that has just been diverted from the strip steel sprayer 11, thereby achieving the effect of initially cooling the hot steam and accelerating the liquefaction speed of the subsequent diverted hot steam in the middle part of the condensation tank 141.
[0030] Further, such as Figures 1 to 6As shown, a hose is fixedly connected to the bottom surface of the water collecting cylinder 142, and one end of the hose extends to the inner wall of the cold liquid collecting tank 116. A conveying roller 111 that is movably sleeved on the upper and lower surfaces of the strip steel plate 13 is provided on the inner wall of the strip steel sprayer 11. A shielding strip 115 is provided at the junction between the top of the direct current pipe 113 and the overlapping shell 114. The top surface of the return pipe 147 extends to the inner wall of the overlapping shell 114. The top surface of the air guide pipe 148 extends to the inner wall of the overlapping shell 114. Two one-way honeycomb disks 145 are fixedly connected to the outer surface of the hollow tube a1. A movable sleeve head a2 is movably sleeved on one side surface of the sealing rotating disk 143, and one end of the circulating guide pipe a3 is fixedly connected to the outer surface of the movable sleeve head a2.
[0031] During operation, a plurality of conveying rollers 111 are sleeved on the upper and lower surfaces of the strip steel plate 13 to limit the position of the strip steel plate 13. When water is sprayed onto the surface of the strip steel plate 13 through the spray pipe 112, a large amount of hot steam will be generated when the water source contacts the high-temperature strip steel plate 13. The generated hot steam will accumulate on the top inner wall of the strip steel sprayer 11. At the same time, the direct current pipe 113 is used to guide the hot steam inside the conveying roller 111 into the inside of the overlapping shell 114, and the bottom surface of the overlapping shell 114 is used to The air guide pipe 148 on the surface injects the hot steam inside the overlapping shell 114 into the interior of the condenser 141. As the hot steam in the middle position of the condenser 141 continues to accumulate, some hot steam that has not yet been liquefied but has already cooled down will pass through the return pipe 147 into the interior of the overlapping shell 114, and mix with some hot steam that has just been diverted from the strip steel sprayer 11, thereby achieving the effect of initially cooling the hot steam and accelerating the liquefaction speed of the subsequent diverted hot steam in the middle part of the condenser 141.
[0032] Working principle: cold water is sprayed onto the top surface of the steel strip 13 in cooperation with the spray pipe 112. When the cold water contacts the surface of the steel strip 13, the cold water will evaporate due to the high temperature on the surface of the steel strip 13. The steam generated by the evaporation of the cold water on the surface of the steel strip 13 will accumulate inside the steel strip sprayer 11. At the same time, the motor 146 is used to rotate the hollow tube a1 and the sealing rotating disk 143 at the same time, thereby driving the guide blades 144 on the outer surface of the sealing rotating disk 143 to rotate. The arc shape on the surface of the guide blades 144 is used to drive the gas around the guide blades 144 to concentrate toward the middle position of the condensation tank 141 when the guide blades 144 rotate. As the gas on the inner wall surfaces at both ends of the condensation tank 141 continues to decrease, the gas inside the condensation tank 141 will drive the stacking The hot steam accumulated in the strip steel shower 11 flows, and the flowing hot steam passes through the direct current pipe 113, the overlapping casing 114 and the air guide pipe 148 into the interior of the condenser 141. The hot steam concentrated in the middle part of the condenser 141 will gradually cool and liquefy. The liquefied liquid will drip to the inside of the condenser 141 due to its own gravity and slide into the inside of the water collecting cylinder 142 to collect the liquid, so as to achieve the effect of using the guide blade 144 to cause gas flow under the rotation, and then transport and guide the hot steam accumulated in the strip steel shower 11, so as to avoid the hot steam in the strip steel shower 11 from accumulating in the strip steel shower 11. When the hot steam accumulates to a certain extent, the hot steam will leak out from the openings at both ends of the strip steel shower 11, thereby polluting the outside air.
[0033] When the hot steam in the middle of the condensation tank 141 is liquefied, the dripping water source will be concentrated in the water collecting tube 142, and at the same time, the low-temperature water source in the water collecting tube 142 will be injected into the cold liquid concentration tank 116 in cooperation with the guide tube on the outer surface of the water collecting tube 142, and at the same time, the cold water in the cold liquid concentration tank 116 that has been cooled will be injected into the hollow tube a1 in cooperation with the circulation guide tube a3. When the low-temperature water source circulates in the hollow tube a1, the low-temperature water source will quickly cool down the surface of the hollow tube a1 and the cooling condensation rod a4. The cooled hollow tube a1 and the cooling condensation rod a4 will contact the hot steam in the condensation tank 141, and the temperature difference will be used to make the hot gas and the low-temperature gas exchange heat quickly, thereby quickly absorbing the high temperature inside the hot steam. At the same time, the motor 146 will cooperate with the motor 146 to The rotation of the hollow tube a1 and the cooling condensation rod a4 increases the stirring and mixing of the cooling condensation rod a4 and the hot steam inside the condensation tank 141, thereby contacting the hot steam at different positions inside the condensation tank 141. The water droplets condensed on the surface of the cooling condensation rod a4 are thrown onto the inner wall of the condensation tank 141 under the centrifugal shaking of the cooling condensation rod a4, and then the water droplets slide downward through the curvature of the inner wall of the condensation tank 141. The water source gathered at the bottom of the inner side of the condensation tank 141 will enter the water collecting tube 142 to collect the water source, thereby achieving the effect of swinging the hollow tube a1 and the cooling condensation rod a4 by the motor 146, thereby increasing the mixing and contact of the cooling condensation rod a4 with the hot steam inside the condensation tank 141, thereby increasing the contact range and area between the cooling condensation rod a4 and the hot steam.
[0034] When the guide blades 144 are rotating, the hot steam inside the condensation tank 141 will be concentrated in the middle part of the condensation tank 141. As the hot steam in the middle part of the condensation tank 141 continues to accumulate, some hot steam that has not yet been liquefied but has been cooled will pass through the return pipe 147 into the interior of the overlap shell 114, and mix with some hot steam that has just been diverted from the strip steel sprayer 11, thereby achieving the effect of initially cooling the hot steam and accelerating the liquefaction speed of the subsequent diverted hot steam in the middle part of the condensation tank 141.
[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
