Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving pumps, and more specifically to an adjustable-speed gas-liquid mixing pump. Background Art

[0002] In aquaculture aeration, a gas-liquid mixing pump forcibly mixes air with water to form a large number of tiny bubbles, significantly increasing the dissolved oxygen content in the water and providing sufficient oxygen guarantee for high-density aquaculture. Its unique gas-liquid shearing technology enables oxygen molecules to be evenly diffused to every corner of the aquaculture pond, effectively improving the problem of insufficient local oxygen supply in traditional aeration methods, and at the same time reducing energy consumption. It has become a key device for improving aquaculture efficiency and ecological benefits in modern intelligent fishery. The patent with the application number CN202011001325.3 discloses a gas-liquid mixing air pump, which includes a main body, blades and liquid flow channels. A number of the blades are circumferentially spaced along the rotation direction on the main body and are used for radially discharging air. A number of the liquid flow channels are circumferentially spaced along the rotation direction on the main body. The outlet of the liquid flow channel faces the radial outside of the main body. The inlet of the liquid flow channel is close to the radial inside of the main body and is used to receive the liquid provided by the liquid supply pipe. The liquid is centrifugally discharged radially along the liquid flow channel. When the existing gas-liquid mixing pump is applied in aquaculture, the water inlet end is located at the bottom of the aquaculture water source to suck the water with a lower oxygen content for aeration, which is beneficial to quickly increase the oxygen content in the water. However, the pipe for sucking water is located at the bottom of the water source, and the pipe is easily blocked by the excrement and silt of the animals in the water, which affects the aeration working process. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides an adjustable-speed gas-liquid mixing pump to solve the problems raised in the above background art.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An adjustable-speed gas-liquid mixing pump includes a speed-regulating motor. A gas-liquid mixing pump is fixedly connected to the right side of the speed-regulating motor. A discharge pipe is fixedly connected to the top of the gas-liquid mixing pump. An intake pipe is fixedly connected to the right side of the gas-liquid mixing pump. A liquid inlet pipe is fixedly connected to the right side of the gas-liquid mixing pump. An anti-blocking component is fixedly connected to the right side of the liquid inlet pipe. A floating component is fixedly connected to the outer wall of the anti-blocking component. The anti-blocking component includes: A drive box, which is fixedly connected to the right side of the liquid inlet pipe; A liquid inlet branch pipe, which is fixedly connected to the front of the drive box; A filter screen, which is fixedly connected to the front of the liquid inlet branch pipe.

[0005] Preferably, a spiral rod is movably connected inside the liquid inlet branch pipe, a prying rod is fixedly connected to the outer wall of the spiral rod at the back of the filter screen, and a raised block is fixedly connected to the back of the filter screen at a position corresponding to the prying rod.

[0006] Preferably, when water flows through the liquid inlet branch pipe, the spiral rod is pushed to rotate, and the spiral rod is driven to rotate with the prying rod.

[0007] Preferably, a rotating blade is movably connected inside the driving box, a push rod is fixedly connected to the top of the rotating blade, a movable frame is fixedly connected to the outer wall of the liquid inlet branch pipe, a spring is provided on the outer wall of the movable frame, and a push scraper is movably connected to the outer wall of the movable frame on the left side of the movable frame.

[0008] Preferably, the pushing rod is driven to rotate by the rotating blade to push the pushing scraper and then compress the spring. If the pushing scraper is not pushed by the spring, the pushing scraper will be pushed to reset.

[0009] Preferably, the floating assembly comprises a spiral plate, the spiral plate is fixedly connected to the bottom of the rotating blade and is located at the bottom of the driving box, and the outer wall of the driving box is fixedly connected with a guide plate.

[0010] Preferably, the top of the rotating blade is movably connected to a universal joint, and the top of the universal joint is movably connected to an air chamber.

[0011] Preferably, the outer wall of the driving box is movably connected to two movable rods, the top of the movable rod is fixedly connected to a limiting block, and the bottom of the driving box is provided with two support plates, the two support plates are movably connected to the corresponding bottom of the movable rod respectively, and the outer walls of the two movable rods are located on the top of the support plates and are fixedly connected to limiting protrusions.

[0012] The present invention provides a speed-adjustable gas-liquid mixing pump having the following beneficial effects: 1. The adjustable speed gas-liquid mixing pump rotates around the axis of the rotating blades with the push rod, so that the push rod pushes the push scraper to slide along the surface of the movable frame. During the sliding process, the push scraper will scrape the outside of the filter to scrape off the attachments on the surface of the filter to avoid impurities clogging the filter and affecting the oxygenation work.

[0013] 2. The adjustable speed gas-liquid mixing pump drives the prying rod to rotate by pushing the spiral rod to be driven by the water flow, so that the prying rod passes through the inclined surface on the raised block to push the filter outward. When the prying rod is separated from the inclined surface of the raised block, the filter will rebound, thereby loosening the impurities filtered on the surface of the filter and making it easy to separate from the surface of the filter, thereby preventing the impurities from clogging the filter and affecting the oxygenation work.

[0014] 3. When the speed-adjustable gas-liquid mixing pump is in a state where the speed-adjusting motor is not working, the air chamber pulls the driving box through buoyancy. At the same time, since the driving box is restricted by the restricting block, the air chamber cannot pull the two movable rods upward together through buoyancy at this time. As a result, the liquid inlet branch pipe is restricted in a fixed position to prevent the liquid inlet branch pipe from getting too close to the soil and excrement at the bottom of the water, thus avoiding excessive impurities being sucked in at the filter screen and causing blockage, which may affect the oxygenation work.

[0015] 4. When the speed-adjustable gas-liquid mixing pump is operating and the speed-adjusting motor switches between low speed and high speed, the driving box rises and falls in the aquaculture water source to change its position, thereby changing the position of the liquid inlet branch pipe, enabling a wider range of water sources to be sucked, being able to suck water from multiple positions, and thus being able to better oxygenate the aquaculture water source.

[0016] 5. When the speed-adjustable gas-liquid mixing pump is operating and the speed-adjusting motor continuously switches between low speed and high speed, it will cause the driving box to continuously rise and fall in the aquaculture water source. As a result, the liquid inlet branch pipe will drive the filter screen to move up and down continuously, and at the same time, the pushing scraper will move up and down. This can make the pushing scraper scrape off the impurities, and the impurities will be carried away by the water flow, further preventing the filter screen from being blocked, and thus better oxygenating the aquaculture water source.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0021] Embodiment 1: Please refer to Figure 1-7 , the present invention provides a technical solution: an adjustable-speed gas-liquid mixing pump, including a speed-regulating motor 1, a gas-liquid mixing pump 2 is fixedly connected to the right side of the speed-regulating motor 1, a discharge pipe 3 is fixedly connected to the top of the gas-liquid mixing pump 2, an intake pipe 4 is fixedly connected to the right side of the gas-liquid mixing pump 2, a liquid inlet pipe 5 is fixedly connected to the right side of the gas-liquid mixing pump 2, an anti-blocking component 6 is fixedly connected to the right side of the liquid inlet pipe 5, and a floating component 7 is fixedly connected to the outer wall of the anti-blocking component 6; The anti-blocking component 6 includes: A drive box 601, and the drive box 601 is fixedly connected to the right side of the liquid inlet pipe 5; A liquid inlet branch pipe 602, and the liquid inlet branch pipe 602 is fixedly connected to the front of the drive box 601; A filter screen 603, and the front of the filter screen 603 is fixedly connected to the front of the liquid inlet branch pipe 602.

[0022] Fix the speed-regulating motor 1, place the discharge pipe 3 in a suitable position in the aquaculture water source, and at the same time allow the intake pipe 4 to suck in external air. Place the drive box 601 at the bottom of the water, start the speed-regulating motor 1, drive the gas-liquid mixing pump 2 through the speed-regulating motor 1, so that the gas-liquid mixing pump 2 sucks in air through the intake pipe 4, sucks in aquaculture water through the liquid inlet pipe 5, and mixes inside the gas-liquid mixing pump 2, and then discharges the water-vapor mixture into the aquaculture water source through the discharge pipe 3 to oxygenate the aquaculture water source.

[0023] When the liquid inlet pipe 5 sucks in the aquaculture water source, the water will pass through the filter screen 603 for filtration and enter the interior of the liquid inlet branch pipe 602, and then be sucked by the gas-liquid mixing pump 2 through the liquid inlet pipe 5 via the drive box 601.

[0024] A screw rod 604 is movably connected inside the liquid inlet branch pipe 602. A prying rod 605 is fixedly connected to the outer wall of the screw rod 604 on the back side of the filter screen 603. A raised block 606 is fixedly connected to the back side of the filter screen 603 at a position corresponding to the prying rod 605.

[0025] When water flows through the liquid inlet branch pipe 602, it will drive the screw rod 604 to rotate, and the screw rod 604 will drive the prying rod 605 to rotate.

[0026] When the water flows in the liquid inlet branch pipe 602, it will drive the screw rod 604 to rotate, and the screw rod 604 will drive the prying rod 605 to rotate. The prying rod 605 will pass through the inclined surface of the raised block 606 on the back side of the filter screen 603 and push the filter screen 603 outward. When the prying rod 605 disengages from the inclined surface of the raised block 606, the filter screen 603 will rebound, and the impurities filtered on the surface of the filter screen 603 will become loose and easily detached from the surface of the filter screen 603.

[0027] A rotating blade 607 is movably connected inside the drive box 601. A push rod 608 is fixedly connected to the top of the rotating blade 607. An activity frame 609 is fixedly connected to the outer wall of the liquid inlet branch pipe 602. A spring 610 is arranged on the outer wall of the activity frame 609. A push scraper 611 is movably connected to the outer wall of the activity frame 609 on the left side of the activity frame 609.

[0028] When the water flows from the liquid inlet branch pipe 602 through the inside of the drive box 601 and into the liquid inlet pipe 5, it will drive the rotating blade 607 to rotate inside the drive box 601. The rotation of the rotating blade 607 will drive the push rod 608 to rotate around the axis of the rotating blade 607.

[0029] The push rod 608 driven by the rotating blade 607 to rotate will push the push scraper 611 and thus compress the spring 610. When the push scraper 611 is not pushed, the spring 610 will push the push scraper 611 to reset.

[0030] During the rotation, the push rod 608 will push the push scraper 611, allowing the push scraper 611 to slide along the surface of the movable frame 609. During the sliding process, the push scraper 611 will scrape the outer side of the filter 603 to scrape off the attachments on the surface of the filter 603, and allow the spring 610 to be compressed until the push rod 608 rotates and detaches from one side of the push scraper 611. At this time, the push rod 608 is no longer pushed by the push rod 608. At this time, the push scraper 611 will be pushed by the spring 610 and reset. During the reset process of the push scraper 611, it will move the outer side of the filter 603 again. The continuous rotation of the push rod 608 will push the push scraper 611 again.

[0031] Example 2: Please refer to Figure 1-8 , based on the first embodiment, the present invention provides a technical solution: The floating assembly 7 includes a spiral plate 701 , which is fixedly connected to the bottom of the rotating blade 607 and located at the bottom of the driving box 601 . A guide plate 708 is fixedly connected to the outer wall of the driving box 601 .

[0032] The rotating blade 607 is driven by the water flow passing through the inside of the driving box 601 to rotate, which will synchronously drive the spiral plate 701 at the bottom to rotate. The rotation of the spiral plate 701 will push the water at the bottom of the driving box 601, thereby generating a reaction force to push the driving box 601 upward. The guide plate 708 on the outer wall of the driving box 601 will play a guiding role to prevent the driving box 601 from changing direction during movement.

[0033] The top of the rotating blade 607 is movably connected to a universal joint 702, and the top of the universal joint 702 is movably connected to an air chamber 703. The internal cavity structure of the air chamber 703 will be affected by buoyancy in water. The universal joint 702 can provide the air chamber 703 with a more direct pulling force on the object, forming a stable mechanical connection with strong anti-interference ability.

[0034] When the speed regulating motor 1 is not working, the buoyancy of the air chamber 703 can pull the driving box 601 to float upward.

[0035] Two movable rods 704 are movably connected to the outer wall of the driving box 601, and a limiting block 705 is fixedly connected to the top of the movable rod 704. Two support plates 706 are arranged at the bottom of the driving box 601. The two support plates 706 are movably connected to the bottom of the corresponding movable rods 704 respectively, and the outer walls of the two movable rods 704 are fixedly connected to the top of the support plates 706 with limiting protrusions 707.

[0036] When the speed-regulating motor 1 is not working, the air chamber 703 pulls the driving box 601 upward by buoyancy. The driving box 601 will move upward along the movable rod 704 until the driving box 601 is restricted by the limiting block 705. At this time, the air chamber 703 cannot pull the two movable rods 704 upward together by buoyancy. When the speed-regulating motor 1 starts to work in the low-speed state, water will flow through the driving box 601, causing the rotating blade 607 to drive the spiral plate 701 to rotate. The generated driving force is not enough to push the driving box 601 to move upward with the two movable rods 704. When the speed-regulating motor 1 works in the high-speed state, the water inlet speed of the liquid inlet pipe 5 will be increased, and then the rotation speed of the rotating blade 607 will be increased to make the universal joint 702 rotate to obtain a larger driving force. When the driving box 601 drives the two movable rods 704 to rise, the two support plates 706 will rotate and contract inward under the action of the water resistance to reduce the upward resistance. When the speed-regulating motor 1 changes to the low-speed working state, the movable rod 704 will move downward due to gravity. At this time, the support plate 706 will expand under the action of the resistance and the expansion angle will be restricted by the limiting protrusion 707 to obtain a larger support area to stand the movable rod 704, thereby restricting the liquid inlet branch pipe 602 in a fixed position to prevent the liquid inlet branch pipe 602 from being too close to the soil and excrement at the bottom of the water.

[0037] When the speed-regulating motor 1 works and switches between low speed and high speed, the driving box 601 rises and falls in the aquaculture water source to change its position, and then changes the position of the liquid inlet branch pipe 602, so that the range of the sucked water source is wider and the water sources at multiple positions can be sucked.

[0038] When the speed-regulating motor 1 continuously switches between low speed and high speed, it will cause the driving box 601 to continuously rise and fall in the aquaculture water source. Then the liquid inlet branch pipe 602 will drive the filter screen 603 to move up and down continuously, and at the same time, the pushing scraper 611 will move up and down. This can make the pushing scraper 611 scrape off the impurities, and the impurities will flow away driven by the water flow, further preventing the filter screen 603 from being blocked.

[0039] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
