Description

A super hydrophobic cold surface air condensation water making device

Technical Field

The present invention relates to the technical field of air condensation water production equipment, and in particular to a super hydrophobic cold surface air condensation water production equipment.

Background Art

The super-hydrophobic cooling surface air condensation water production device is often composed of solar photovoltaic panels, compressors, condensers, throttling devices, water storage tanks, condensation plates and batteries.

When the current super-hydrophobic cooling surface air condensation water production device uses a condensation plate to cool the air, the water vapor in the air condenses on the surface of the condensation plate under forced convection or natural convection with the air. However, after the water vapor in the air condenses on the condensation plate, the condensed water droplets on the condensation plate will not fall immediately, but will be adsorbed on the condensation plate, thereby reducing the heat exchange area between the condensation plate and the air, hindering the water vapor in the air from releasing heat to the condensation plate to condense new water droplets; and when the air flow rate injected into the water tank decreases, if the coolant in the cooling tube body inside the condensation plate maintains a stable flow rate, the cooling efficiency of the coolant will be reduced.

To this end, we proposed a super-hydrophobic cold surface air condensation water production device.

The U-shaped plate 10 and the annular groove 9 slide against each other, and the U-shaped plate 10 will not interfere with the rotation of the circular tube 8. When the circular tube 8 slides in the vertical direction, it will drive the U-shaped plate 10 to move synchronously.

The inner walls at both ends of each telescopic airbag 35 are commonly fixedly connected to a return spring 36 .

An electronic valve is installed inside the air outlet hole 39. The one-way air outlet pipe 33 only allows the piston 41 to squeeze the air inside the box body 31 into the telescopic airbag 35. When the piston 41 slides to the left in a sealed manner inside the box body 31 (refer to Figure 3), no air is squeezed into the telescopic airbag 35 at this time. The electronic valve is connected to the controller. Then, the electronic valve inside the air outlet hole 39 is opened by the controller. The controller can control the electronic valve by means of interval time, etc. This is a prior art and will not be described in detail here. Under the pulling force of the return spring 36, the telescopic airbag 35 is contracted from the extended state. The air outlet hole 39 is opposite to the condensation plate 3, so that the air inside the telescopic airbag 35 can contact the condensation plate 3 again to form water droplets to achieve the purpose of water production. At the same time, the telescopic airbag 35 drives the scraper 37 to slide in the opposite direction.

A bracket 2 is fixedly connected to the inner wall at the bottom of the water making tank 1, and a condensing plate 3 is fixedly connected to the bracket 2. The condensing plate 3 is tilted, and a cooling tube body is provided inside the condensing plate 3. The liquid inlet pipe 5 and the cooling tube body built into the condensing plate 3 are fixedly connected. The external cooling liquid is injected into the cooling tube body of the condensing plate 3 through the liquid inlet pipe 5 and circulates, thereby enabling the condensing plate 3 to achieve the purpose of cooling and condensing the air. The cooling liquid circulating in the liquid inlet pipe 5 can circulate in the cooling tube body of the condensing plate 3 and reflux for cooling again. A supporting plate 40 is fixedly connected to the inner wall of the water making tank 1, and the bottom end of the main shaft 6 is rotatably connected to the top wall of the supporting plate 40.

In the present invention, the air required for water production is circulated from the inside of the air inlet pipe 4 to the inside of the water production tank 1. The air required for water production has a certain initial kinetic energy, and then when passing through the impeller 7, it will drive the impeller 7 to rotate rapidly, and the impeller 7 will drive the main shaft 6 to rotate synchronously, and the main shaft 6 will drive the rotating rod 13 set on its side wall to rotate, and the rotating rod 13 will drive the V-shaped rods 14 set at both ends to move synchronously, and each V-shaped rod 14 will drive the floating ball 15 fixedly connected at one end thereof to rotate with the main shaft 6 as the center of the circle. The floating ball 15 itself has a certain gravity, so when the floating ball 15 rotates rapidly, it will move upward under the action of centrifugal force.

Each floating ball 15 will drive the V-shaped rod 14 fixedly connected thereto to rotate a certain angle with the rotating rod 13 as the axis, then the V-shaped rod 14 will drive the cross plate 11 to move downward along the axis direction of the main shaft 6 for a distance through the inclined rod 12, then the cross plate 11 will drive the round tube 8 to slide downward for a distance synchronously, because the U-shaped plate 10 and the annular groove 9 opened on the side wall of the round tube 8 slide against each other, then the round tube 8 will drive the U-shaped plate 10 to move downward for a distance through the annular groove 9, then the U-shaped plate 10 will drive the cross bar 17 fixedly connected thereto to move synchronously, and the cross bar 17 moves with the top rod 16 as the center. The center of the circle rotates a certain angle, and then the end of the cross bar 17 away from the U-shaped plate 10 will drive the connecting rod 18 to move upward for a certain distance, and the connecting rod 18 drives the adjusting rod 21 rotatably connected to it to rotate a certain angle. Since the adjusting rod 21 is fixedly connected to the side wall of the rotating rod 19, and the sealing plate 20 is fixedly connected to the side wall of the rotating rod 19, the adjusting rod 21 will drive the sealing plate 20 to rotate a certain angle through the rotating rod 19, so that the initial state of the sealing plate 20 and the liquid inlet pipe 5 in a sealed state begins to change, and the coolant can enter the cooling pipe body of the condensing plate 3 through the liquid inlet pipe 5 for circulation.

When the air flow rate inside the intake pipe 4 is greater, the rotation speed of the air-driven impeller 7 is greater, the rotation speed of the main shaft 6 is faster, the centrifugal force on the two floating balls 15 is greater, the upward swing amplitude of the floating ball 15 is greater, and the downward displacement of the circular tube 8 is greater. Then, under the action of the U-shaped plate 10, the cross bar 17 and the connecting rod 18 and other structures, the rotation angle of the rotating rod 19 is greater, the opening and closing degree of the sealing plate 20 and the liquid inlet pipe 5 is greater, and the flow rate of the coolant flowing into the liquid inlet pipe 5 is faster, which is convenient for continuous cooling and condensation of a large amount of air overflowing from the intake pipe 4, so as to achieve the purpose of adjusting the flow rate of the coolant flowing inside the condensation plate 3 according to the size of the intake volume.

During the rotation of the main shaft 6, the main shaft 6 will also drive the half gear 22 to rotate, and the tooth part of the half gear 22 is meshed with the rack 24. When the half gear 22 and the rack 24 are meshed, the half gear 22 will drive the rack 24 to slide a certain distance inside the slide rail 23, and then the rack 24 will drive one end of the bellows 27 to deviate from the sliding direction of the rack 24 by a certain angle through the L-shaped rod 26. Then, after the air enters the bellows 27 from the intake pipe 4, the flow direction will change and overflow along the direction of the deviation of the bellows 27. When the half gear 22 and the rack 24 are disengaged, at this time, under the elastic force of the tension spring 25, the rack 24 will slide in the reverse direction, and then the rack 24 will slide back and forth inside the slide rail 23. The rack 24 drives the bellows 27 to swing back and forth in the horizontal plane through the L-shaped rod 26, so that the air flowing out of the bellows 27 contacts with different surface parts of the condensation plate 3, thereby improving the range and effect of air cooling and condensation.

And during the rotation of the main shaft 6, the main shaft 6 will also drive the circular plate 28 fixedly connected to its top to rotate, then the circular plate 28 will drive the circular shaft 29 eccentrically fixedly connected to its top to rotate synchronously, and the circular shaft 29 will drive the push rod 30 rotatably connected to its side wall to move, so that the push rod 30 drives the piston 41 rotatably connected to it to slide back and forth in a sealed manner inside the box body 31, then the piston 41 will draw the uncondensed air at the top of the water making tank 1 into the box body 31 through the one-way air inlet pipe 32, and then squeeze the air into the two telescopic air bags 35 through the one-way air outlet pipe 33. The telescopic air bags 35 are made of elastic material and can be telescopic and changed along their axial direction, then the two telescopic air bags 35 will drive the scraper 37 to scrape on the condensation plate 3, promote the aggregation of the small water droplets condensed on the condensation plate 3, and then these small water droplets gather together and flow to the bottom of the inner cavity of the water making tank 1 for water making and collection.
