Description

Technical Field

[0001] The invention relates to the technical field of spray cooling, in particular to a spray cooling device for a spinning room air conditioning unit. Background Art

[0002] In the polyester filament production system, the spinning process is the core process link. The precise control of its various process parameters directly affects the physical performance indicators of the final product. The environment of the spinning room is also a factor that affects the cooling and forming of polyester filaments. In the spinning workshop, due to equipment operation and raw material processing, the return air often carries a high content of oil and dust. At the same time, the workshop temperature is also high. In order to improve this situation, a spray section water spray system is usually used to conduct a comprehensive washing, dust reduction and humidification control on the air source entering the air conditioning system.

[0003] There are defects in the existing technology: There is a shortcoming in using this spray humidification technology. Industrial water is generally not completely purified, and its water quality usually contains a large amount of suspended impurities and other particulate matter. After long-term operation, these impurities will enter the spray system with the water flow, and gradually accumulate in the spray pipes and nozzles, forming blockages. This will not only lead to uneven distribution of water mist and reduced spraying effect, but may also cause the humidification and dust reduction functions in some areas to fail. Summary of the Invention

[0004] The object of the present invention is to provide a spray cooling device for a spinning room air conditioning unit to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: the spray cooling device includes a spray device, one end of which is equipped with an air inlet pipe and a sewage tank, and the other end of which is equipped with an air outlet pipe. A coarse filter device, a fine filter device, and a bottom plate are sequentially installed above the spray device along the direction of water flow, and a clean water tank is installed on the bottom plate. Water flows into the coarse filter device, which removes large impurities in the water flow. The filtered water flows into the fine filter device, which removes fine impurities in the water flow. The filtered water flows into the clean water tank for storage. The water in the clean water tank flows into the spray device, spraying and cooling the return air entering from the air inlet pipe. The treated return air is discharged from the air outlet pipe, and the sewage after spraying enters the sewage tank.

[0006] The coarse filtration device includes a support platform, which is installed on the spray device. A cyclone is installed on the support platform. A first water inlet pipe is installed on one side of the cyclone. A siphon is installed inside the cyclone. One end of the siphon is installed on the fine filtration device. A slag discharge pipe is installed at one end of the cyclone. A slag discharge valve is installed in the slag discharge pipe, and the slag discharge valve is connected to the control system.

[0007] The siphon includes a low siphon section, one end of which is connected to a high siphon section, one end of which is connected to a siphon outlet section, one end of which is connected to a drainage section, and one end of which is mounted on a fine filtration device. Water flows into the cyclone from the first water inlet pipe. After entering the cyclone, the water forms a high-speed rotating vortex. Large impurities are subjected to a strong centrifugal force, forced to move outward and settle to the bottom, thereby achieving preliminary separation and filtration. When the water level in the cyclone rises to the high siphon section, the water flows into the low siphon section, passes through the high siphon section, reaches the siphon outlet section, and finally is discharged from the drainage section into the second water inlet pipe. When the water level drops to the low siphon section, the water stops flowing, ensuring that impurities suspended in the water have sufficient time to settle, further improving the efficiency of the entire filtration process.

[0008] The fine filtering device includes a base, which is mounted on the spray device, and a first water pump is mounted on the spray device. A shell is mounted on the base, and a filter cartridge is slidably connected to the interior of the shell. A connecting column and a connecting pipe are mounted on one end of the filter cartridge, and a resist column is mounted in the connecting pipe. A scraper structure is mounted between the shell and the filter cartridge, and a cylinder, a second water inlet pipe, a suction pipe and a backwash pipe are mounted on one end of the shell. A drain pipe is mounted on the other end of the shell, and the drain pipe is connected to the sewage tank through a pipe. A one-way valve is mounted in the backwash pipe, and the drainage section is mounted on the second water inlet pipe. One end of the first water pump is mounted on the clean water tank, and the other end of the first water pump is mounted on the suction pipe. The connecting pipe slides in the backwash pipe, the cylinder rod of the cylinder is mounted on the filter cartridge, the connecting column is located below the second water inlet pipe, and the first water pump and the cylinder are connected to the control system. Water flows into the shell from the second water inlet pipe and enters the filter cartridge from the outside of the filter cartridge. The filter cartridge filters the fine impurities in the water flow. The control system controls the first water pump to start, and the first water pump pumps the water flow inside the filter cartridge into the clean water tank through the pumping pipe.

[0009] The scraper structure includes a circular ring, which is rotatably installed at the bottom of the shell. A support plate is installed inside the circular ring, a first rotating shaft is installed on one side of the support plate, the first rotating shaft is located inside the sewage pipe, a first drainage fan is installed on one end of the first rotating shaft, an L-shaped plate is installed on one end of the circular ring, and a brush is provided on one side of the L-shaped plate. After a period of use, the first water pump drains the water inside the filter cartridge, the control cylinder starts, and the cylinder rod drives the filter cartridge to slide in the shell toward the cylinder until the connecting column blocks the second water inlet pipe. At this time, the bottom of the filter cartridge leaves the ring, and the column pushes the one-way valve open. The water in the clean water tank flows from the backwash pipe to the connecting pipe and enters the inner side of the filter cartridge from the connecting pipe. The water flows from the inside of the filter cartridge to the outside of the filter cartridge, quickly carrying away the impurities deposited on the outside of the filter cartridge from the surface of the filter cartridge, and the cleaned sewage flows out from the sewage pipe. The sewage drives the first drain fan to rotate, the first drain fan drives the first rotating shaft to rotate, the first rotating shaft drives the support plate to rotate, the support plate drives the ring to rotate, the ring drives the L-shaped plate to rotate around the filter cartridge, and the L-shaped plate drives the brush to thoroughly scrape off the stubborn dirt that is difficult to be washed away by simple water flow due to surface tension or adhesion, thereby achieving all-round cleaning of the filter cartridge.

A main water spray pipe and a drainage structure are installed inside the box body, one end of the main water spray pipe is installed on the clean water tank, and the main water spray pipe is located above the drainage structure. An auxiliary water spray pipe and a water spray structure are installed at one end of the main water spray pipe, one end of the auxiliary water spray pipe is installed on the clean water tank, and one end of the auxiliary water spray pipe is installed with a temperature sensing structure.

[0011] The temperature sensing structure includes an intake pipe mounted on one end of the auxiliary water spray pipe. A fixed plate is mounted within the intake pipe, and a guide column is slidably connected to the fixed plate. A plunger is mounted on one end of the guide column, and a plunger head is mounted on one end of the plunger. A return spring is mounted between the plunger and the fixed plate. A limit block is mounted on the guide column, and a bimetallic block is slidably connected between the fixed plate and the limit block. Filtered water flows from the clean water tank into the main and auxiliary water spray pipes. Water flow in the auxiliary water spray pipe is blocked by the plunger head. When return air enters the tank through the intake pipe, the return air enters through the intake pipe. When the bimetallic block senses a rise in temperature, it bends to one side, driving the limit block to move. The limit block drives the guide column to slide away from the fixed plate. The guide column drives the plunger to move, and the plunger drives the plunger head to move. Water flows from the auxiliary water spray pipe to the main water spray pipe, increasing the water flow rate and simultaneously driving the second drainage fan to rotate faster.

[0012] The water spray structure includes a second rotating shaft, which rotates inside the main water spray pipe. A second drainage fan, a first bevel gear, a first support block and a swing structure are installed on the second rotating shaft. A third rotating shaft is installed at one end of the first support block. A second bevel gear is installed at one end of the third rotating shaft. The first bevel gear and the second bevel gear are meshed. A universal joint is installed at one end of the universal joint. A fourth rotating shaft is installed at one end of the fourth rotating shaft. A nozzle seat is installed at one end of the nozzle seat. A nozzle is installed at one end of the nozzle seat. The external rotation of the nozzle seat is connected to a nozzle shell. A bellows is installed at one end of the nozzle shell. A nozzle pipe is installed at one end of the bellows. The nozzle pipe is installed on the main water spray pipe.

The first bevel gear drives the third bevel gear to rotate, the third bevel gear drives the fifth rotating shaft to rotate, the fifth rotating shaft drives the cylinder to rotate, the cylinder drives the cam groove, the cam groove drives the L-shaped cam to rotate around the fixed block, one end of the L-shaped cam drives the nozzle shell to swing, the nozzle shell drives the nozzle seat and the bellows to swing, the nozzle seat swings while rotating, which can change the water outlet angle of the nozzle, forming a constantly changing spray trajectory, ensuring that the sprayed water flow can cover the entire return air area, avoiding dead corners such as missed spraying or insufficient spraying.

[0014] The drainage structure includes a first gear mounted on one end of a second rotating shaft. A water collection trough is mounted within the housing, and a spiral rod is mounted within the trough. The spiral rod rotates on the housing. A second gear is mounted on one end of the spiral rod. A belt is mounted on the second gear and the first gear. The other end of the spiral rod is located in the sewage tank. A second water pump is mounted on the housing, one end of the second water pump is mounted on the sewage tank, and the other end of the second water pump is mounted on the first water inlet pipe. The second water pump is connected to a control system. The second rotating shaft drives the first gear to rotate, which in turn drives the belt. The belt drives the second gear, which in turn drives the spiral rod. The spiral rod transports the sprayed sewage to the sewage tank. After a period of time, the second water pump is activated to pump the sewage from the sewage tank into the first water inlet pipe, thereby achieving water recycling and saving industrial water.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The coarse filtration device of the present invention uses a cyclone. When water flows into the cyclone, it forms a high-speed rotating vortex. Large impurities are subjected to a strong centrifugal force, forced to move outward and settle to the bottom, thereby achieving preliminary separation and filtration. At the same time, a siphon is used to intermittently discharge the filtered water in the middle. The residence time of the water in the cyclone is extended, allowing the suspended impurities in it to have sufficient time to settle, further improving the efficiency of the entire filtration process.

[0017] 2. The fine filtration device of the present invention adopts a backwashing structure. After the filter cartridge has been used for a period of time, suspended particles, oil stains and other fine impurities from the fluid will inevitably accumulate on the filter cartridge surface. Backwashing the filter cartridge quickly removes the deposited impurities from the filter cartridge surface. At the same time, the scraper structure moves smoothly along the filter cartridge surface under the push of the backwash water flow. The brush on the scraper exerts its physical friction to thoroughly scrape off stubborn dirt that is difficult to be washed away by simple water flow due to surface tension or adhesion. This achieves all-round cleaning of the filter cartridge, can extend the service life of the filter cartridge, and reduce the equipment maintenance frequency and operating costs.

[0018] 3. The spray device of the present invention is driven by the kinetic energy of the water flow. The nozzle can rotate and swing at the same time under the action of the water flow, so that the nozzle can change the water outlet angle during operation to form a constantly changing spray trajectory, ensuring that the sprayed water flow can cover the entire return air area, avoiding the problem of dead corners such as leakage or insufficient spraying. At the same time, it can increase the water flow rate according to the increase in temperature, accelerate the rotation and swing speed of the nozzle, and ensure that the sprayed water mist acts on the air with a higher frequency and a denser coverage method, further promoting the evaporation and heat absorption of water, and achieving faster cooling. The speed of the drainage system will also be increased accordingly to avoid excessive accumulation of water in the spray area and affect the subsequent spraying effect. This positive feedback mechanism enables the entire system to automatically adjust according to environmental changes. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example: Figures 1-9 As shown, the present invention provides a technical solution. The spray cooling device includes a spray device 6. An air inlet pipe 1 and a sewage tank 7 are installed at one end of the spray device 6, and an air outlet pipe 2 is installed at the other end of the spray device 6. A coarse filter device 3, a fine filter device 4, and a bottom plate 8 are installed above the spray device 6 in the direction of water flow. A clean water tank 5 is installed on the bottom plate 8. Water flows into the coarse filter device 3, which removes large impurities from the water flow. The filtered water flows into the fine filter device 4, which removes fine impurities from the water flow. The filtered water flows into the clean water tank 5 for storage. The water in the clean water tank 5 flows into the spray device 6, spraying and cooling the return air entering from the air inlet pipe 1. The treated return air is discharged from the air outlet pipe 2, and the sewage after spraying enters the sewage tank 7.

[0031] The coarse filtration device 3 includes a support platform 31, which is installed on the spray device 6. A cyclone 32 is installed on the support platform 31. A first water inlet pipe 33 is installed on one side of the cyclone 32. A siphon tube 35 is installed inside the cyclone 32.

Water flows into the cyclone 32 from the first water inlet pipe 33. After entering the cyclone 32, a high-speed rotating vortex is formed. Large impurities are subjected to a strong centrifugal force, forced to move outward and settle to the bottom, thereby achieving preliminary separation and filtration. When the water level in the cyclone 32 rises to the siphon high section 352, the water flows into the siphon low section 351, passes through the siphon high section 352, reaches the siphon outlet section 353, and finally is discharged from the drainage section 354 to the second water inlet pipe 45. When the water level drops to the siphon low section 351, the water stops flowing, which can ensure that the impurities suspended in the water have enough time to settle, further improving the efficiency of the entire filtration process.

An L-shaped plate 484 is installed at one end of the circular ring 481, and a brush is provided on one side of the L-shaped plate 484.

[0035] After a period of use, the first water pump 43 drains the water inside the filter cartridge 47, and the control cylinder 44 is started. The cylinder rod of the cylinder 44 drives the filter cartridge 47 to slide in the housing 42 toward the cylinder 44 until the connecting column blocks the second water inlet pipe 45. At this time, the bottom of the filter cartridge 47 leaves the ring 481, and the column pushes the one-way valve open. The water in the clean water tank 5 flows from the backwash pipe 49 to the connecting pipe 41, and enters the inner side of the filter cartridge 47 from the connecting pipe 41. The water flows from the inner side of the filter cartridge 47 to the outer side of the filter cartridge 47, and the outer side of the filter cartridge 47 is filled with water.

The second rotating shaft 651 drives the first gear 661 to rotate, the first gear 661 drives the belt 663 to rotate, the belt 663 drives the second gear 662 to rotate, and the second gear 662 drives the screw rod 665 to rotate. The screw rod 665 transports the sprayed sewage to the sewage tank 7. After a period of time, the second water pump is controlled to start and pump the sewage in the sewage tank 7 into the first water inlet pipe 33, thereby realizing water recycling and saving industrial water.

[0043] Working principle of the present invention:

[0044] The industrial water flows into the cyclone 32 from the first water inlet pipe 33. After entering the cyclone 32, a high-speed rotating vortex is formed. Large impurities are subjected to a strong centrifugal force, forced to move outward and settle to the bottom, thereby achieving preliminary separation and filtration. When the water level in the cyclone 32 rises to the siphon high section 352, the water flows into the siphon low section 351, passes through the siphon high section 352, reaches the siphon outlet section 353, and finally is discharged from the drainage section 354 to the second water inlet pipe 45. When the water level drops to the siphon low section 351, the water stops flowing, which can ensure that the impurities suspended in the water have enough time to settle, further improving the efficiency of the entire filtration process.

[0045] The filtered water flows into the shell 42 from the second water inlet pipe 45, and enters the filter cartridge 47 from the outside of the filter cartridge 47. The filter cartridge 47 filters the fine impurities in the water flow. The control system controls the first water pump 43 to start, and the first water pump 43 pumps the water flow inside the filter cartridge 47 into the clean water tank 5 through the pumping pipe 46.

[0046] After a period of use, the first water pump 43 drains the water inside the filter cartridge 47, and the control cylinder 44 is started. The cylinder rod of the cylinder 44 drives the filter cartridge 47 to slide in the housing 42 toward the cylinder 44 until the connecting column blocks the second water inlet pipe 45. At this time, the bottom of the filter cartridge 47 leaves the ring 481, and the column pushes the one-way valve open. The water in the clean water tank 5 flows from the backwash pipe 49 to the connecting pipe 41, and enters the inner side of the filter cartridge 47 from the connecting pipe 41. The water flows from the inner side of the filter cartridge 47 to the outer side of the filter cartridge 47, and the outer side of the filter cartridge 47 is filled with water. The deposited impurities are quickly carried away from the surface of the filter cartridge 47, and the cleaned sewage flows out from the sewage pipe. The sewage drives the first drainage fan 483 to rotate, the first drainage fan 483 drives the first rotating shaft 485 to rotate, the first rotating shaft 485 drives the support plate 482 to rotate, the support plate 482 drives the ring 481 to rotate, the ring 481 drives the L-shaped plate 484 to rotate around the filter cartridge 47, and the L-shaped plate 484 drives the brush to completely scrape off the stubborn dirt that is difficult to be washed away by simple water flow due to surface tension or adhesion, thereby achieving all-round cleaning of the filter cartridge 47.

[0047] The filtered water flows from the clean water tank 5 into the main water spray pipe 62 and the auxiliary water spray pipe 63. The water flow in the auxiliary water spray pipe 63 is blocked by the plunger head. The water flow in the main water spray pipe 62 drives the second drainage fan 652 to rotate, the second drainage fan 652 drives the second rotating shaft 651 to rotate, the second rotating shaft 651 drives the first bevel gear 653 to rotate, the first bevel gear 653 drives the second bevel gear 654 and the third bevel gear 6573 to rotate, the second bevel gear 654 drives the third rotating shaft 656 to rotate, the third rotating shaft 656 drives the universal joint 655 to rotate, the universal joint 655 drives the fourth rotating shaft to rotate, the fourth rotating shaft drives the nozzle seat to rotate, and the nozzle The seat drives the water flow in the sprinkler head to rotate, the third bevel gear 6573 drives the fifth rotating shaft 6574 to rotate, the fifth rotating shaft 6574 drives the cylinder to rotate, the cylinder drives the cam slot 6575, the cam slot 6575 drives the L-shaped cam 6576 to rotate around the fixed block 6572, one end of the L-shaped cam 6576 drives the sprinkler head shell 659 to swing, the sprinkler head shell 659 drives the sprinkler head seat and the bellows 658 to swing, the sprinkler head seat swings while rotating, which can change the water outlet angle of the sprinkler head, forming a constantly changing spray trajectory, ensuring that the sprayed water flow can cover the entire return air area, avoiding the problem of dead corners such as missed spraying or insufficient spraying.

[0048] When the return air enters the box 61 from the air inlet pipe 1, the water flow sprayed by the nozzle sprays the return air to cool it down. When the return air passes through the air inlet pipe, the bimetallic block 646 senses the temperature increase and the bimetallic block 646 will bend to one side. The bimetallic block 646 drives the limit block 645 to move, and the limit block 645 drives the guide column 642 to slide in the fixed plate 641 away from the fixed plate 641. The guide column 642 drives the plunger 643 to move, and the plunger 643 drives the plunger head to move. Water flows from the auxiliary spray pipe 63 to the main spray pipe 62 to increase the water flow rate, and at the same time drives the second drainage fan 652 to rotate faster, which speeds up the rotation and swing speed of the nozzle, ensuring that the sprayed water mist acts on the air with a higher frequency and denser coverage, further promoting the evaporation and heat absorption of water, achieving faster cooling, and the speed of the drainage system will also be increased to avoid excessive accumulation of water in the spray area and affecting the subsequent spraying effect. This positive feedback mechanism enables the entire system to automatically adjust according to environmental changes.

[0049] The return air after spraying and cooling is discharged from the air outlet pipe 2. The second rotating shaft 651 drives the first gear 661 to rotate, the first gear 661 drives the belt 663 to rotate, the belt 663 drives the second gear 662 to rotate, and the second gear 662 drives the screw rod 665 to rotate. The screw rod 665 transports the sprayed sewage to the sewage tank 7. After a period of time, the industrial water is stopped from being transported to the first water inlet pipe 33, and the second water pump is controlled to start. The second water pump pumps the sewage in the sewage tank 7 into the first water inlet pipe 33, thereby realizing water recycling and saving industrial water.
