Description

Technical Field

[0001] This invention relates to the field of degassing tank technology, and in particular to a degassing tank with adjustable degassing mode. Background Technology

[0002] Gas buildup in the cooling water system can cause air lock, hindering system circulation and affecting normal operation. At the same time, air bubbles in the water reduce heat transfer efficiency, and oxygen in the water can cause oxygen corrosion, shortening the service life of the equipment. Therefore, a degassing tank is needed to degas the cooling water.

[0003] In actual use of cooling water, when the cooling water is urgently needed, it needs to be degassed quickly so that it can be used as soon as possible. When the cooling water is not urgently needed or when more thorough degasing is required, it needs to be thoroughly degassed. However, existing cooling water degasing tanks cannot adjust the degasing method according to actual usage needs. Summary of the Invention

[0004] In order to solve the problem that degassing tanks for cooling water cannot adjust the degassing mode according to actual usage needs, this invention proposes a degassing tank with an adjustable degassing mode.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a degassing tank with adjustable degassing method, comprising a tank body, a tank cover installed at the upper port of the tank body, and a water inlet mechanism for uniformly spraying water into the tank body installed on the outer side of the tank body near the upper port. A water injection pipe is fixed on the right side of the tank body near the lower end, and a second valve is installed on the water injection pipe. Multiple evenly distributed support legs are fixed at the lower end of the tank body, and a drain pipe is fixed at the lower end of the tank body, with a third valve installed on the drain pipe. A flow stabilizing mechanism for collecting and guiding the sprayed water downward to the bottom of the inner side of the tank body is installed on the inner side of the tank body below the water inlet mechanism. An ultrasonic transmission mechanism is provided on the inner side of the tank body, penetrating downward through the center of the flow stabilizing mechanism. The lower end of the ultrasonic transmission mechanism is near the bottom of the inner side of the tank body, and the upper end of the ultrasonic transmission mechanism passes through the tank cover and is connected to an ultrasonic generator. A drive mechanism for driving the entire ultrasonic transmission mechanism to rotate is fixed on the upper surface of the tank cover, and an air extraction pipe is fixed on the upper surface of the tank cover near the right side, with one end of the air extraction pipe connected to a vacuum pump.

[0006] By adopting the above technical solution, when rapid degassing of cooling water is required and the degree of degassing is not critical, a vacuum pump is used to evacuate the tank, and water is quickly introduced into the tank through a water injection pipe. The water entering the tank is agitated by an ultrasonic transmission mechanism driven by a drive mechanism, causing residual gas to quickly precipitate. When the degassing speed requirement is not high, but the degree of degassing is critical, a vacuum pump is used to evacuate the tank, and water is then introduced into the tank in a mist form through a water inlet mechanism, causing the gas in the water to quickly precipitate. The water is then smoothly introduced into the bottom inner side of the tank through a flow stabilizing mechanism. At this point, the ultrasonic transmission mechanism sends ultrasonic waves emitted by an ultrasonic generator into the water for ultrasonic vibration, causing the gas in the water to precipitate and slowly rise to the surface. Simultaneously, the drive mechanism drives the ultrasonic transmission mechanism to rotate slowly, thus providing comprehensive ultrasonic vibration to the water, making the degassing process more thorough. The degassing method can be adjusted according to actual usage requirements.

[0007] Optionally, the water inlet mechanism includes an annular tube fitted around the outside of the tank, with multiple nozzles fixed on the inner circumferential surface of the annular tube, and one end of each nozzle passing through the side wall of the tank. A water inlet pipe is fixed to the outside of the annular tube, and a first valve is installed on the water inlet pipe.

[0008] By adopting the above technical solution, the water inlet pipe sends water into the annular pipe and sprays it evenly onto the inside of the tank through multiple nozzles.

[0009] Optionally, the flow stabilizing mechanism includes a water collection box, with evenly arranged water inlet holes on the upper surface of the water collection box, and multiple evenly arranged guide pipes fixed on the lower side of the water collection box near the edge, with the edge of the water collection box in close contact with the inner wall of the tank.

[0010] By adopting the above technical solution, the water collection box collects the water entering the tank through the water inlet and sends it directly to the bottom of the tank through multiple guide pipes, thereby avoiding water surging that would affect the upward floating of gas.

[0011] Optionally, the ultrasonic transmission mechanism includes a rotating frame, with ultrasonic transducers installed on the lower side of the rotating frame near both ends. A conductive slip ring is fixed to the upper end of the rotating frame. The output end of the conductive slip ring is connected to the ultrasonic transducer via a wire, and the input end of the conductive slip ring is connected to the ultrasonic generator via a wire. The conductive slip ring is fixed to the can lid by a second support plate.

[0012] By adopting the above technical solution, the conductive slip ring transmits the ultrasonic signal generated by the ultrasonic generator to the ultrasonic transducer, thereby generating ultrasonic waves and transmitting them to the water in the tank, thus promoting the rapid release of gas from the water.

[0013] Optionally, the rotating frame includes a transverse support tube, a rotating tube fixed at the upper middle position of the support tube, and hanging tubes fixed at both ends of the lower side of the support tube. A first annular retaining rib is fixed at the outer side of the hanging tube near the lower end.

[0014] By adopting the above technical solution, the rotating frame is rotatably mounted on the can lid using a rotating tube, and is driven to rotate by the rotating tube in conjunction with the drive mechanism.

[0015] Optionally, a connecting pipe is fixed to the upper end of the ultrasonic transducer, and a sleeve is connected to the upper end of the connecting pipe. A second annular retaining rib is fixed near the upper end of the connecting pipe, and an annular retaining groove is opened on the inner side of both the upper and lower ends of the sleeve.

[0016] By adopting the above technical solution, the ultrasonic transducer is fixedly connected to the connecting pipe and the sleeve pipe, and the sleeve pipe is fixedly connected to the hanging pipe, thereby realizing the fixed connection between the ultrasonic transducer and the rotating frame.

[0017] Optionally, the drive mechanism includes a motor and a rotating gear fixedly mounted on the rotating tube. One side of the motor is fixed to the can lid by a fixed bracket, and a drive gear that meshes with the rotating gear is fixed on the output shaft of the motor.

[0018] By adopting the above technical solution, the motor drives the drive gear to rotate, and the rotating drive gear drives the rotating gear to rotate, thereby further driving the rotating tube to rotate.

[0019] Optionally, a movable support frame is provided at the bottom of the tank, and the legs at the bottom of the tank are fixed to the support frame.

[0020] By adopting the above technical solution, the tank body is supported by a movable support frame, which facilitates the adjustment of the tank body's position.

[0021] Optionally, the support frame includes an upper first support plate and a lower lifting plate. The lower surface of the first support plate is fixed with support columns that penetrate downward through the lifting plate near the four corners. The lower surface of the lifting plate is fixed with evenly distributed roller legs. The upper surface of the first support plate is fixed with lifting motors near the front and rear sides. The lower end of the output shaft of the lifting motor passes through the first support plate and is fixed with a threaded rod that penetrates the lifting plate.

[0022] By adopting the above technical solution, the first support plate is fixedly supported by the support column, thereby fixing the first support plate to the entire degassing tank, and the roller support legs are moved by the descent of the lifting plate.

[0023] Optionally, an annular connecting plate is fixed to the upper port edge of the tank body, and a sealing ring is fixed to the upper surface of the connecting plate. An mounting plate is fixed to the lower port edge of the tank cover, and the mounting plate is fixedly connected to the connecting plate by screws.

[0024] By adopting the above technical solution, the tank body uses screws to fix the mounting plate and connecting plate together, thereby completing the fixed connection between the tank cover and the tank body.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] Firstly, when rapid degassing of cooling water is required and the degree of degassing is not critical, a vacuum pump is used to create a vacuum inside the tank. Water is then quickly introduced into the tank through a water injection pipe. The water entering the tank is agitated by an ultrasonic transmission mechanism driven by a drive mechanism, causing residual gas to be quickly released. When the degassing speed requirement is not high but the degree of degassing is critical, a vacuum pump is used to create a vacuum inside the tank. Water is then introduced into the tank in a mist form through a water inlet mechanism, causing gas in the water to be released rapidly. The water is then smoothly introduced into the bottom of the tank through a flow stabilizing mechanism. At this point, ultrasonic waves generated by an ultrasonic generator are sent into the water through the ultrasonic transmission mechanism, causing the gas in the water to be released and slowly rise to the surface. Simultaneously, the drive mechanism drives the ultrasonic transmission mechanism to rotate slowly, thus providing comprehensive ultrasonic vibration to the water, resulting in a more thorough degassing process. The degassing method can be adjusted according to actual usage requirements for a more thorough treatment.

[0027] Secondly, the water is smoothly delivered into the bottom of the tank by the set flow stabilizing mechanism, which can avoid the water at the bottom of the tank from surging, so as not to affect the gas rising to the surface.

[0028] Finally, the support frame uses support columns to fix the first support plate, thereby fixing the first support plate to the entire degassing tank. The lowering of the lifting plate allows the roller outriggers to touch the ground for movement, thus facilitating the switching between fixed support and moving support for the entire degassing tank.

[0045] like Figure 1 As shown, a degassing tank with adjustable degassing method includes a tank body 3. A tank cover 1 is installed at the upper port of the tank body 3. A water injection pipe 32 is fixed on the right side of the tank body 3 near the lower end, and a second valve is installed on the water injection pipe 32. An ultrasonic transmission mechanism 7 is provided inside the tank body 3, penetrating downward through the center of a flow stabilizing mechanism 9. The lower end of the ultrasonic transmission mechanism 7 is near the bottom of the inner side of the tank body 3, and the upper end of the ultrasonic transmission mechanism 7 passes through the tank cover 1 and is connected to an ultrasonic generator. A drive is fixed on the upper surface of the tank cover 1. The entire ultrasonic transmission mechanism 7 is driven by a rotating drive mechanism 8, and an air extraction pipe 6 is fixed on the upper surface of the tank cover 1 near the right side. One end of the air extraction pipe 6 is connected to a vacuum pump. When rapid degassing of cooling water is required and the degree of degassing is not high, the vacuum pump is used to evacuate the tank 3, and water is quickly sent into the tank 3 through the water injection pipe 32. The water entering the tank 3 is stirred by the ultrasonic transmission mechanism 7 driven by the drive mechanism 8, which causes the residual gas to be quickly released.

[0046] A water inlet mechanism 2 is installed on the outer side of the tank 3 near the upper port, which sprays water evenly into the tank 3. Multiple evenly distributed support legs 31 are fixed to the lower end of the tank 3, and a drain pipe 4 is also fixed to the lower end of the tank 3. A third valve is installed on the drain pipe 4. A flow stabilizing mechanism 9 is installed on the inner side of the tank 3, below the water inlet mechanism 2, to collect the sprayed water and guide it downwards to the bottom of the inner side of the tank 3. When the degassing speed requirement is not high, but the degassing degree requirement is high, a vacuum is drawn inside the tank 3 using a vacuum pump. At this time, the water is atomized by the water inlet mechanism 2. The water is fed into the tank 3, causing the gas in the water to be released quickly. The water is then smoothly fed into the bottom of the inner side of the tank 3 through the flow stabilizing mechanism 9. At this time, the ultrasonic wave generated by the ultrasonic generator is sent to the water through the ultrasonic transmission mechanism 7 to cause ultrasonic vibration, which causes the gas in the water to be released and slowly float to the surface. At the same time, the drive mechanism 8 drives the ultrasonic transmission mechanism 7 to rotate slowly, thereby performing ultrasonic vibration on the water body, making the degassing treatment more thorough. The degassing method can be adjusted according to the actual use requirements.

[0047] like Figure 2 As shown, the water inlet mechanism 2 includes an annular tube 23 fitted around the outside of the tank body 3. Multiple nozzles 24 are fixed on the inner circumferential surface of the annular tube 23, and one end of the nozzle 24 passes through the side wall of the tank body 3. The annular tube 23 sends the water supplied by the water inlet pipe 21 into the tank body 3 in a spray manner through the nozzles 24.

[0048] An inlet pipe 21 is fixed to the outside of the annular pipe 23. A first valve 22 is installed on the inlet pipe 21. By opening the first valve 22, the water pump sends water to the inlet pipe 21. The inlet pipe 21 sends water into the annular pipe 23 and sprays it evenly onto the inside of the tank 3 through multiple nozzles 24.

[0049] like Figure 3 As shown, the flow stabilizing mechanism 9 includes a water collection box 92. The upper surface of the water collection box 92 is provided with evenly arranged water inlet holes 91, and a plurality of evenly arranged guide pipes 93 are fixed on the lower side of the water collection box 92 near the edge. The edge of the water collection box 92 is in close contact with the inner wall of the tank 3. The water collection box 92 collects the water entering the tank 3 through the water inlet holes 91 and sends it directly to the bottom of the water in the tank 3 through the plurality of guide pipes 93, thereby preventing the water from surging and affecting the upward floating of the gas.

[0050] like Figure 4 As shown, the ultrasonic transmission mechanism 7 includes a rotating frame 73. Ultrasonic transducers 74 are installed on the lower side of the rotating frame 73 near both ends. A conductive slip ring 71 is fixed on the upper end of the rotating frame 73. The output end of the conductive slip ring 71 is connected to the ultrasonic transducer 74 through a wire, and the input end of the conductive slip ring 71 is connected to the ultrasonic generator through a wire. The conductive slip ring 71 can be used to conduct electrical transmission while the rotating frame 73 is rotating.

[0051] The conductive slip ring 71 is fixed to the tank cover 1 by the second support plate 72. The conductive slip ring 71 transmits the ultrasonic signal generated by the ultrasonic generator to the ultrasonic transducer 74 to generate ultrasonic waves and transmit them to the water in the tank 3, thereby promoting the rapid release of gas from the water.

[0052] like Figure 5 As shown, the rotating frame 73 includes a horizontal support tube 733, and a rotating tube 732 is fixed at the middle position of the upper side of the support tube 733. The rotating frame 73 is rotatably mounted on the can cover 1 by means of the rotating tube 732, and is driven to rotate by means of the rotating tube 732 in conjunction with the drive mechanism 8.

[0053] The support pipe 733 is fixed with a hanging pipe 731 near both ends on the lower side. The hanging pipe 731 is fixed with a ring-shaped first retaining rib 734 near the lower end on the outer side. The support pipe 733 is connected to the sleeve pipe 742 by the hanging pipe 731, and the hanging pipe 731 is locked in place with the retaining groove 741 in the sleeve pipe 742 by the first retaining rib 734.

[0054] like Figure 6 As shown, a connecting pipe 744 is fixed to the upper end of the ultrasonic transducer 74, and a sleeve pipe 742 is connected to the upper end of the connecting pipe 744. The ultrasonic transducer 74 is fixedly connected to the sleeve pipe 742 by the connecting pipe 744, and the sleeve pipe 742 is fixedly connected to the hanging pipe 731, thereby realizing the fixed connection between the ultrasonic transducer 74 and the rotating frame 73.

[0055] The connecting pipe 744 is fixed with an annular second retaining rib 743 near the upper end. The inner sides of the upper and lower ends of the sleeve pipe 742 are provided with annular grooves 741. The connecting pipe 744 is inserted into the inner side of the sleeve pipe 742 and is clamped and fixed by the second retaining rib 743 and the grooves 741.

[0056] like Figure 7 As shown, the drive mechanism 8 includes a motor 82 and a rotating gear 83 fixedly mounted on the rotating tube 732. One side of the motor 82 is fixed to the can lid 1 by a fixed bracket 81, and a drive gear 84 that meshes with the rotating gear 83 is fixed on the output shaft of the motor 82. The motor 82 drives the drive gear 84 to rotate, and the rotating drive gear 84 drives the rotating gear 83 to rotate, thereby further driving the rotating tube 732 to rotate.

[0057] like Figure 1 As shown, a movable support frame 5 is provided below the tank body 3, and the support leg 31 at the lower end of the tank body 3 is fixed on the support frame 5. The tank body 3 is moved and supported by the movable support frame 5, which facilitates the adjustment of the position of the tank body 3.

[0058] like Figure 8 As shown, the support frame 5 includes an upper first support plate 52 and a lower lifting plate 54. The lower surface of the first support plate 52 is fixed with support columns 53 that penetrate downward through the lifting plate 54 near the four corners. The lower surface of the lifting plate 54 is fixed with evenly distributed roller support legs 55. The support columns 53 are used to fix and support the first support plate 52, so that the first support plate 52 fixes and supports the entire degassing tank. The lowering of the lifting plate 54 allows the roller support legs 55 to touch the ground and move.

[0059] Lifting motors 51 are fixed on the upper surface of the first support plate 52 near the front and rear sides. The lower end of the output shaft of the lifting motor 51 passes through the first support plate 52 and is fixed with a screw 56 that is threaded through the lifting plate 54. The lifting motor 51 drives the screw 56 to rotate, and the rotating screw 56 drives the lifting plate 54 to rise and fall.

[0060] like Figure 9 As shown, an annular connecting plate 33 is fixed to the upper port edge of the tank body 3, and an mounting plate 11 is fixed to the lower port edge of the tank cover 1. The mounting plate 11 is fixedly connected to the connecting plate 33 by screws. The tank body 3 uses screws to fix the mounting plate 11 and the connecting plate 33, thereby completing the fixed connection between the tank cover 1 and the tank body 3.

[0061] A sealing ring 34 is fixed on the upper surface of the connecting plate 33. The sealing ring 34 is used for sealing when the connecting plate 33 and the mounting plate 11 are mated.

[0062] In this embodiment, when degassing the cooling water, a vacuum pump and a vacuum pipe 6 are used to create a vacuum inside the tank 3. The first valve 22 is opened to allow the water pump to send water to the inlet pipe 21. The inlet pipe 21 sends the water into the annular pipe 23 and sprays it evenly onto the inside of the tank 3 in the form of a spray through multiple nozzles 24. The gas in the mist-like water is separated under vacuum. The water entering the tank 3 falls onto the upper surface of the water collection box 92 and is collected by the water inlet hole 91. The water is then sent directly to the bottom of the tank 3 through multiple guide pipes 93. At this time, the ultrasonic generator sends a signal to the ultrasonic transducer 74 to convert the vibration wave into a signal that is transmitted to the water. The vibration wave separates the gas in the water. The degassed water is then discharged by opening the third valve. The above are preferred embodiments of the present invention. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
