Description

Technical Field

[0001] This application relates to the technical field of closed cooling towers, and more particularly, to a closed cooling tower that facilitates adjusting the spraying angle. Background Art

[0002] Closed cooling towers are commonly used for circulating water cooling in industrial production or civil equipment, and can cool high-temperature water to a temperature close to the atmospheric temperature. In a closed cooling tower, the circulating water is cooled in a closed loop, and only the heat energy carried by the circulating water is dissipated to the external atmospheric environment, ensuring that the circulating medium has no contact with the external environment, and having the advantages of unchanged circulating medium composition, no evaporation, no consumption, and no impurities.

[0003] When a closed cooling tower is in use, the spraying assembly inside the machine case directly sprays on the surface of the coil. Due to the large distance between adjacent nozzles, the area of the water surface sprayed by the nozzles covering the coil is not comprehensive enough, resulting in some areas of the coil not being able to contact the sprayed water source, affecting the spraying cooling effect. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application provides a closed cooling tower that facilitates adjusting the spraying angle to solve the problem that the distance between adjacent nozzles is large, the area of the water surface sprayed by the nozzles covering the coil is not comprehensive enough, resulting in some areas of the coil not being able to contact the sprayed water source, affecting the spraying cooling effect.

[0005] A closed cooling tower that facilitates adjusting the spraying angle according to an embodiment of this application includes: a box-type main body mechanism, a spraying water circulation mechanism, and a spraying mechanism.

[0006] The box-type main body mechanism includes a machine case, a chassis, a net plate, an exhaust fan, and a coil. The chassis is arranged at the bottom of the machine case. An air outlet is formed at the top of the machine case, and the exhaust fan is installed inside the air outlet. Air inlets are arranged around the lower section of the machine case, and the net plate is embedded inside the air inlets. A water outlet is arranged at the bottom of the machine case, and the coil is arranged inside the machine case;

[0007] The spraying water circulation mechanism includes a spraying pump, a water collecting hopper, a return pipe, and a water outlet pipe. The water collecting hopper is installed at the bottom of the machine case and is located below the water outlet. One end of the return pipe is connected to the bottom of the water collecting hopper, and the other end of the return pipe is connected to the water inlet port of the spraying pump. One end of the water outlet pipe is connected to the water outlet port of the spraying pump;

[0008] The spray mechanism includes a spray branch pipe, a nozzle, a first cross bar, a rotation drive assembly, a collar, an interface pipe and a connecting hose. A plurality of the spray branch pipes are equidistantly arranged above the coil, and the spray branch pipe is connected to the other end of the water outlet pipe. A plurality of the interface pipes are equidistantly connected and arranged at the bottom of the spray branch pipe. The top end of the connecting hose is connected to the bottom end of the interface pipe, and the bottom end of the connecting hose is connected to the nozzle. The collar is fixedly sleeved on the outside of the nozzle, and adjacent collars are fixed to the two ends of the first cross bar. The first cross bar close to one side of the chassis rotates and passes through the side wall of the chassis. The rotation drive assembly is installed on the outside of the chassis, and the rotation drive assembly drives the first cross bar to rotate.

[0009] When the water temperature inside the coil is between 32°C and 45°C, the exhaust fan runs to draw air from the inside of the chassis, and the outside air is supplied into the chassis through the mesh panel on the side of the chassis, so that the air inside the chassis circulates quickly, that is, the temperature on the coil is quickly brought out to the outside of the chassis.

[0010] When the water temperature inside the coil exceeds 45°C, the spray pump activates. It draws water from the bottom of the chassis through the return pipe and water collection hopper. The pressurized water then flows through the outlet pipe into the spray branch pipe. The spray branch pipe then directs the pressurized water through the bottom interface pipe and connecting hose, ultimately spraying it out of the nozzle. The sprayed water then falls onto the outer surface of the coil, rapidly cooling the hot water inside.

[0011] While the spray pump is running and pressurizing the nozzle, the rotating drive assembly drives the first crossbar to rotate forward and reverse. The rotating crossbar simultaneously rotates the collar, which in turn rotates the nozzle, thereby adjusting the nozzle's spray angle. Adjusting the nozzle's spray angle allows the water at the spray point to contact a larger area of the coil below, increasing the contact area between the spray water source and the coil. This, combined with the exhaust fan, drives the warm water source to quickly flow out of the chassis, further improving the coil's cooling efficiency.

[0012] In some embodiments of the present application, the rotation drive assembly includes a servo motor, a first driving pulley, a first driven pulley and a first transmission belt, the output shaft end of the servo motor is connected to the end of one of the first cross bars, the first driving pulley and the first driven pulley are respectively fixedly mounted on the outside of adjacent first cross bars, and the first transmission belt is connected to the first driving pulley and the first driven pulley.

[0013] In some embodiments of the present application, a bracket seat is fixedly provided on one side of the chassis, and the servo motor is installed on the top of the bracket seat.

[0014] In some embodiments of the present application, the chassis includes a lower chassis shell, an upper chassis shell, and gusset plates. The four gusset plates are respectively fixedly arranged at the four corners of the lower chassis shell and the upper chassis shell, and the mesh plate is fixedly arranged between adjacent gusset plates.

[0015] In some embodiments of the present application, the exhaust fan includes a housing, a fan blade, and a driving motor. The housing is fixedly arranged inside the air outlet, the fan blade is located inside the housing, and the output shaft end of the driving motor is connected to the fan blade.

[0016] In some embodiments of the present application, a fixing frame is arranged outside the driving motor, and the fixing frame is fixedly arranged inside the air outlet.

[0017] In some embodiments of the present application, a plurality of steel bars are arranged on the top of the housing.

[0018] In some embodiments of the present application, a first valve is arranged on the return water pipe.

[0019] In some embodiments of the present application, a second valve is arranged on the water outlet pipe.

[0020] In some embodiments of the present application, a filter screen is fixedly arranged inside the water collecting hopper.

[0021] Although the water source sprayed and dissipated by the spray head of the closed cooling tower that is convenient for adjusting the spray angle increases the contact area with the coil, the sprayed water source is mainly sprayed onto the upper arc surface of the coil pipeline, and the contact area between the sprayed water source and the bottom arc surface of the coil is small.

[0022] The closed cooling tower that is convenient for adjusting the spray angle further includes a spray water dispersion mechanism. The spray water dispersion mechanism includes a second cross bar, a blade plate, a first connection transmission member, a second connection transmission member, and a third connection transmission member. A plurality of the second cross bars are respectively arranged at equal intervals in layers inside the gap of the coil. Three of the blade plates are fixedly arranged in a circular array outside the second cross bar, and both ends of the second cross bar respectively penetrate through the side wall of the chassis in a rotating manner. The first connection transmission member is connected to one end of a first cross bar and one end of a second cross bar. The second connection transmission member is respectively connected to the ends of the laterally adjacent second cross bars. The third connection transmission member is respectively connected to the ends of the vertically adjacent second cross bars on one side.

[0023] In some embodiments of the present application, the first connection transmission member includes a driving sprocket, a driven sprocket, and a chain. The driving sprocket is fixedly sleeved on one end of a first cross bar, the driven sprocket is fixedly sleeved on one end of a second cross bar, and the chain is connected to the driving sprocket and the driven sprocket.

[0024] While the servo motor in the rotational drive assembly drives the first crossbar to rotate, it drives the second crossbar to rotate through the cooperation of the driving sprocket, driven sprocket and chain in the first connecting transmission member. The rotating second crossbar drives the external blade plate to rotate, and the rotating blade plate splashes part of the sprayed water source reversely to the bottom arc surface of the coil pipe, so that both the top arc surface and the bottom arc surface of the coil pipe can be more fully contacted with the sprayed water source, further improving the cooling efficiency of the coil.

[0025] The rotating second crossbar drives the external blade plate to rotate, and the rotating blade plate drives the surrounding air to flow. It has the function of a fan while rotating. Cooperating with the exhaust fan on the top of the chassis can make the air inside the chassis flow more rapidly. The flowing air contacts more with the heat on the surface of the water source, quickly taking away the heat in the sprayed water source inside the chassis, that is, further rapidly improving the cooling efficiency of the coil.

[0026] In some embodiments of the present application, the second connecting transmission member includes a second driving pulley, a second driven pulley and a second transmission belt. The second driving pulley and the second driven pulley are respectively fixedly sleeved on the ends of the second crossbars adjacent horizontally, and the second transmission belt is connected between the second driving pulley and the second driven pulley.

[0027] In some embodiments of the present application, the third connecting transmission member includes a third driving pulley, a third driven pulley and a third transmission belt. The third driving pulley and the third driven pulley are respectively fixedly sleeved on the ends of the second crossbars adjacent vertically on one side, and the third transmission belt is connected between the third driving pulley and the third driven pulley.

[0028] The water source inside the closed cooling tower chassis that is convenient for adjusting the spraying angle cannot be added and supplemented in time.

[0029] This closed cooling tower that is convenient for adjusting the spraying angle further includes a water adding component. The water adding component includes a water injection connecting pipe, a water injection inlet pipe, a water inlet valve and a ball valve. The water inlet valve is connected to one end of the water injection connecting pipe and the water injection inlet pipe. The other end of the water injection connecting pipe penetrates through the side wall of the chassis, and the water injection connecting pipe is located below the mesh plate. The ball valve is located inside the chassis, and the ball valve is butt - mounted with the end of the water injection connecting pipe.

[0030] The water injection inlet pipe is communicated with an external water adding source pipe, and the water inlet valve is opened. When the water level at the bottom side inside the chassis decreases, the ball valve opens, and the water source is replenished into the bottom side inside the chassis through the water injection connecting pipe. The gradually rising water level drives the sphere in the ball valve to move gradually upward until the ball valve closes. That is, this method can automatically supplement the water source into the chassis.

[0031] The beneficial effects of the present application are as follows: A closed cooling tower that facilitates the adjustment of the spraying angle obtained through the above design. During use, while the spraying pump operates to pressurize and perform spraying operations from the nozzles, the rotation drive assembly can drive the first crossbar to rotate forward and backward for adjustment. The rotating first crossbar simultaneously drives the collar to rotate, and the rotating collar drives the nozzle to rotate, thereby adjusting the spraying angle of the nozzle. After the spraying angle of the nozzle is adjusted, the water source at the spraying location can come into contact with the coil below over a larger area, enhancing the contact area between the spraying water source and the coil. In cooperation with the exhaust fan, the temperature in the spraying water source is quickly discharged outside the chassis, further improving the cooling efficiency of the coil.

[0046] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0047] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0049] A closed cooling tower with a conveniently adjustable spraying angle according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0050] Please refer to Figures 1 - 10 , a closed cooling tower with a conveniently adjustable spraying angle according to an embodiment of the present application includes: a box-shaped main body mechanism 10, a spraying water circulation mechanism 20, and a spraying mechanism 30.

[0051] Among them, hot water enters the interior of the box-shaped main body mechanism 10. The spraying water circulation mechanism 20 and the spraying mechanism 30 cooperate with each other, and the nozzles 320 with adjustable angles increase the spraying area and improve the cooling and refrigeration effect.

[0052] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 7The box-type main body mechanism 10 includes a chassis 110, a base frame 120, a mesh panel 130, an exhaust fan 140 and a coil 160. The base frame 120 is arranged at the bottom of the chassis 110, an air outlet 150 is opened at the top of the chassis 110, and the exhaust fan 140 is installed inside the air outlet 150. Air inlets are provided on all four sides of the lower section of the chassis 110, and the mesh panel 130 is embedded inside the air inlet. A water outlet is provided at the bottom of the chassis 110, and the coil 160 is arranged inside the chassis 110. The spray water circulation mechanism 20 includes a spray pump 210, a water collecting hopper 220, a return pipe 230 and a water outlet pipe 240. The water collecting hopper 220 is installed at the bottom of the chassis 110, and the water collecting hopper 220 and the chassis 110 are fixed by bolts, and a sealing gasket is provided between the water collecting hopper 220 and the chassis 110; and the water collecting hopper 220 is located below the water outlet. A first valve 250 is provided on the return pipe 230. A second valve 260 is provided on the outlet pipe 240. A filter is fixedly provided inside the water collecting bucket 220 to filter impurities in the spray water. One end of the return pipe 230 is connected to the bottom of the water collecting bucket 220, and the other end of the return pipe 230 is connected to the water inlet port of the spray pump 210. One end of the outlet pipe 240 is connected to the water outlet port of the spray pump 210. The spray mechanism 30 includes a spray branch pipe 310, a nozzle 320, a first cross bar 330, a rotation drive assembly 340, a collar 350, an interface pipe 360 and a connecting hose 370. Multiple spray branch pipes 310 are equidistantly arranged above the coil 160, and the spray branch pipes 310 are connected to the other end of the outlet pipe 240. Several interface pipes 360 are equidistantly connected and arranged at the bottom of the spray branch pipe 310. The top end of the connecting hose 370 is connected to the bottom end of the interface tube 360, and the bottom end of the connecting hose 370 is connected to the nozzle 320. The collar 350 is fixedly mounted on the outside of the nozzle 320, and the collar 350 and the nozzle 320 are fixed by bolts. The collars 350 are fixed to the ends of the first crossbar 330, and the collars 350 and the first crossbar 330 are fixed by welding. The first crossbar 330 on the side closest to the chassis 110 rotates and extends through the side wall of the chassis 110. The rotation drive assembly 340 is installed on the outside of the chassis 110, and the rotation drive assembly 340 drives the rotation of the first crossbar 330.

[0053] When the water source temperature inside the coil 160 is between 32°C and 45°C, the exhaust fan 140 runs to extract air from the inside of the chassis 110, and external air is supplied into the inside of the chassis 110 through the mesh panel 130 on the side of the chassis 110, so that the air inside the chassis 110 circulates quickly, that is, the temperature on the coil 160 is quickly brought out to the outside of the chassis 110.

[0054] When the water source temperature inside the coil 160 is higher than 45°C, the spray pump 210 starts to operate. The spray pump 210 extracts the water source from the bottom side inside the chassis 110 through the return pipe 230 and the water collecting hopper 220. The water source pressurized by the spray pump 210 then enters the spray branch pipe 310 through the outlet pipe 240. The spray branch pipe 310 sprays the pressurized water source through the interface pipe 360 and the connecting hose 370 at the bottom and finally sprays it out from the nozzle 320. The sprayed water source drenches the outer surface of the coil 160, causing the hot water inside the coil 160 to cool down rapidly.

[0055] While the spray pump 210 is operating and pressurizing for spraying operation from the nozzle 320, the rotation drive assembly 340 can drive the first cross bar 330 to rotate forward and backward. The rotating first cross bar 330 drives the collar 350 to rotate at the same time, and the rotating collar 350 drives the nozzle 320 to rotate, thereby adjusting the spraying angle of the nozzle 320. After the spraying angle of the nozzle 320 is adjusted, the water source at the spraying position can come into contact with the lower coil 160 over a larger area, enhancing the contact area between the sprayed water source and the coil 160. Cooperating with the exhaust fan 140 to quickly discharge the temperature in the sprayed water source to the outside of the chassis 110 further improves the cooling efficiency of the coil 160.

[0056] In the above specific implementation manner, please refer to Figure 6 , the rotation drive assembly 340 includes a servo motor 341, a first driving pulley 342, a first driven pulley 343, and a first transmission belt 344.

The servo motor 341 is installed on the top of the support base 345, that is, used to support the servo motor 341. The output shaft end of the servo motor 341 drives a first cross bar 330 to rotate, and drives all the first cross bars 330 to rotate through the cooperation of the first driving pulley 342, the first driven pulley 343, and the first transmission belt 344. The rotating first cross bar 330 drives the collar 350 and the nozzle 320 to rotate, that is, to adjust the spraying angle of the nozzle 320. The servo motor 341 rotates at 120° clockwise and counterclockwise repeatedly. The rotation of the servo motor 341 is controlled and adjusted by a corresponding control system. The control system for the angle rotation adjustment of the servo motor 341 is a publicly known technology and can be understood by those skilled in the art, so it will not be elaborated here.

[0057] Furthermore, please refer to Figure 2, the chassis 110 includes a lower chassis shell 111, an upper chassis shell 112, and gusset plates 113. Four gusset plates 113 are respectively fixedly arranged at the four corners of the lower chassis shell 111 and the upper chassis shell 112, and the mesh plate 130 is fixedly arranged between adjacent gusset plates 113. The lower chassis shell 111 is used to add a spray water source, and the gusset plates 113 are fixedly connected to the lower chassis shell 111 and the upper chassis shell 112 by welding.

[0058] For specific settings, please refer to Figure 3 , the exhaust fan 140 includes a housing 141, fan blades 142, and a drive motor 143. The housing 141 is fixedly arranged inside the air outlet 150, the fan blades 142 are located inside the housing 141, and the output shaft end of the drive motor 143 is connected to the fan blades 142. A fixing frame 144 is arranged outside the drive motor 143, and the fixing frame 144 is fixedly arranged inside the air outlet 150. A number of steel bars 145 are arranged on the top of the housing 141. The fixing frame 144 is used to fixedly install the drive motor 143, and the output shaft end of the drive motor 143 drives the fan blades 142 to rotate to discharge the air inside the chassis 110 to the outside of the chassis 110.

[0059] Although the water source sprayed and dissipated by the closed cooling tower nozzle 320 that is convenient for adjusting the spraying angle increases the contact area with the coil 160, the sprayed water source is mainly sprayed onto the upper arc surface of the coil 160 pipeline, and the contact area between the sprayed water source and the bottom arc surface of the coil 160 is small.

[0060] Please refer to Figure 8 and Figure 9 , the closed cooling tower that is convenient for adjusting the spraying angle further includes a spray water dispersion mechanism 40. The spray water dispersion mechanism 40 includes a second cross bar 410, a blade plate 420, a first connecting transmission member 430, a second connecting transmission member 440, and a third connecting transmission member 450.

Three blade plates 420 are fixedly arranged in a circular array outside the second cross bar 410, and the blade plates 420 and the second cross bar 410 are fixedly connected by welding; and both ends of the second cross bar 410 respectively penetrate through the side wall of the chassis 110 rotatably. The first connecting transmission member 430 is connected to one end of a first cross bar 330 and one end of a second cross bar 410. The second connecting transmission member 440 is respectively connected to the ends of the laterally adjacent second cross bars 410. The third connecting transmission member 450 is respectively connected to the ends of the vertically adjacent second cross bars 410 on one side. The first connecting transmission member 430 includes a driving sprocket 431, a driven sprocket 432, and a chain 433. The driving sprocket 431 is fixedly sleeved on one end of a first cross bar 330, and the driven sprocket 432 is fixedly sleeved on one end of a second cross bar 410, and the chain 433 is connected between the driving sprocket 431 and the driven sprocket 432. Among them, the diameter ratio of the driving sprocket 431 to the driven sprocket 432 is at least 7:1.

[0061] While the servo motor 341 in the rotational drive assembly 340 drives the first crossbar 330 to rotate, the first connecting transmission member 430 drives the second crossbar 410 to rotate through the cooperation of the driving sprocket 431, the driven sprocket 432 and the chain 433. The rotating second crossbar 410 drives the external blade plate 420 to rotate, and the rotating blade plate 420 splashes a part of the sprayed water source in the reverse direction to the bottom arc surface of the coil pipe 160, so that both the top arc surface and the bottom arc surface of the coil pipe 160 can be more fully contacted with the sprayed water source, further improving the cooling efficiency of the coil pipe 160.

[0062] The rotating second crossbar 410 drives the external blade plate 420 to rotate, and the rotating blade plate 420 drives the surrounding air to flow. During rotation, it has the function of a fan. Cooperating with the exhaust fan 140 at the top of the chassis 110 can make the air inside the chassis 110 flow more rapidly. The flowing air contacts more heat on the surface of the water source, quickly taking away the heat in the sprayed water source inside the chassis 110, that is, further rapidly improving the cooling efficiency of the coil pipe 160.

[0063] In some embodiments of the present application, please refer to Figure 9 , the second connecting transmission member 440 includes a second driving pulley 441, a second driven pulley 442 and a second transmission belt 443. The second driving pulley 441 and the second driven pulley 442 are respectively fixedly sleeved on the ends of the laterally adjacent second crossbars 410, and the second transmission belt 443 is connected to the second driving pulley 441 and the second driven pulley 442. The rotating first crossbar 330 drives the lateral second crossbar 410 to rotate through the cooperation of the second driving pulley 441, the second driven pulley 442 and the second transmission belt 443. The third connecting transmission member 450 includes a third driving pulley 451, a third driven pulley 452 and a third transmission belt 453.

The third driving pulley 451, the third driven pulley 452 and the third transmission belt 453 cooperate to drive the second crossbar 410 on one side vertically to rotate.

[0064] The water source inside the closed cooling tower chassis 110 that is convenient for adjusting the spraying angle cannot be added and replenished in time.
