DETAILED DESCRIPTION
[0019] See also Figure 1-4 The utility model provides a low-pressure rotary film deaerator, including a water tank 1, a deaerator tower head 2 is arranged on the top of the water tank 1, supports 3 are fixed on both sides of the bottom surface of the water tank 1, a rotating shaft 4 is rotatably connected at the middle position of the surface of one side of the water tank 1, one side of the rotating shaft 4 extends to the inner cavity position of the water tank 1, a motor 5 is fixed at the bottom position of the surface of one side of the water tank 1, a first gear 6 is fixedly sleeved on the output end of the motor 5, a second gear 7 is fixedly sleeved at the position of the outer circumference of the rotating shaft 4 near the first gear 6, the first gear 6 and the second gear 7 are meshedly connected, a connecting disk 10 is fixed at the position of the rotating shaft 4 extending to the inner cavity of the water tank 1, a connecting shaft 11 is fixed on one side of the connecting disk 10, and the connecting shaft 11 A rotating disk 14 is fixed on one side, and movable rods 17 are rotatably connected to the surfaces of both ends of the rotating disk 14. A sleeve 23 is sleeved on the outside of the movable rod 17, and a cleaning sleeve 24 is sleeved on the outer circumferential surface of the sleeve 23. A plurality of toggle plates 12 that are equidistantly distributed and arranged are fixed on the outer circumferential surface of the connecting shaft 11. By starting the motor 5, the rotating shaft 4 can be rotated, so that the rotating disk 14 can be rotated, so that the movable rod 17 can make a circular motion, so that the cleaning sleeve 24 can fit the inner circumferential surface of the water tank 1 and gradually perform friction cleaning, so that the scale attached to the inner circumferential surface of the water tank 1 can be removed, thereby ensuring the long-term use stability of the device and facilitating the cleaning of the inner circumferential surface of the water tank 1.
[0020] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that a gear ring 13 is fixed at a position of the inner cavity surface of the water tank 1 away from one side of the motor 5, and third circular gears 16 are meshed at both ends of the gear ring 13. A rotating shaft 15 is fixed through the middle position of the third circular gear 16, and the surface of one side of the rotating shaft 15 is rotatably connected with the surface of the rotating disk 14. A fourth circular gear 18 is meshed at a position of the third circular gear 16 away from one end of the gear ring 13, and the fourth circular gear 18 is fixedly sleeved and connected to a movable rod 17 at an adjacent position. When the rotating disk 14 rotates, the third circular gear 16 is driven to make a circular motion, so that the rotating shaft 15 can rotate under the meshing action of the third circular gear 16 and the gear ring 13, and the movable rod 17 can rotate under the meshing action of two adjacent third circular gears 16 and the fourth circular gear 18, and the rotation direction of the movable rod 17 is opposite to the rotation direction of the rotating disk 14.
[0021] Further as Figure 3 As shown, it is worth explaining in detail that an annular groove 19 is opened at the position of the inner cavity surface of the water tank 1 near the rotating disk 14, and a sealing ring 20 is slidably inserted inside the annular groove 19. The inner circumference of the sealing ring 20 is fixed to the outer circumference of the rotating disk 14. Since the sealing ring 20 extends to the inside of the annular groove 19, the inner cavity of the water tank 1 located on the side of the ring gear 13 and the inner cavity away from the side of the ring gear 13 can be blocked by the rotating disk 14, thereby preventing the liquid in the inner cavity of the water tank 1 from affecting the ring gear 13, the third circular gear 16 and the fourth circular gear 18.
[0022] Further as Figure 3 As shown, it is worth explaining in detail that the outer circumference of the two ends of the outer circumference of the movable rod 17 is provided with a T-shaped slot 21, and a T-shaped plug block 22 is inserted inside the slot 21. The ends of the two adjacent plug blocks 22 that are away from each other are fixed to the inner circumference of the sleeve 23. When the sleeve 23 needs to be inserted into the outer circumference of the movable rod 17, the two plug blocks 22 fixed on the inner circumference of the sleeve 23 are extended to the inside of the adjacent slots 21, so that the sleeve 23 can be sleeved on the outer circumference of the movable rod 17 at the adjacent position, and when the movable rod 17 rotates, the sleeve 23 can be rotated due to the interference between the slot 21 and the plug block 22, thereby driving the cleaning sleeve 24 to move along the movement trajectory of the sleeve 23.
[0023] This solution has the following working process: in actual use, when it is necessary to clean the inner cavity of the water tank 1, water is added to the inner cavity of the water tank 1 through the water inlet pipe, and then the first gear 6 is rotated by starting the motor 5, so that the first gear 6 can mesh with the second gear 7 to rotate the rotating shaft 4, so that the connecting disk 10 can rotate, so that the connecting shaft 11 and the rotating disk 14 can rotate, and the rotation of the connecting shaft 11 can drive the toggle plate 12 to make a circular motion, so that the toggle plate 12 rotates and the water in the inner cavity of the water tank 1 is moved to the inner circumferential surface of the water tank 1, and the rotation of the rotating disk 14 drives the third circular gear 16 to make a circular motion, so that the meshing of the third circular gear 16 and the ring gear 13 can be achieved. The rotating shaft 15 can be rotated, so that the movable rod 17 can be rotated under the meshing action of the two adjacent third circular gears 16 and the fourth circular gear 18, and the rotation direction of the movable rod 17 is opposite to the rotation direction of the rotating disk 14, and when the movable rod 17 rotates, the sleeve 23 can be rotated under the interference of the slot 21 and the plug block 22, thereby driving the cleaning sleeve 24 to move along the movement trajectory of the sleeve 23, so that the cleaning sleeve 24 can fit the inner circumferential surface of the water tank 1 and make a self-rotation motion opposite to the rotation direction of the rotating disk 14 when making a circular motion, thereby increasing the friction between the cleaning sleeve 24 and the inner circumferential surface of the water tank 1, so that the scale attached to the inner circumferential surface of the water tank 1 can be removed, and then the valve of the drain pipe of the water tank 1 is opened to let the drain pipe mixed with scale flow out.
[0024] According to the above working process, it can be known that: by starting the motor 5, the rotating shaft 4 can rotate, thereby the rotating disk 14 rotates, so that the movable rod 17 makes a circular motion while rotating itself, so that the cleaning sleeve 24 can gradually rub and clean the inner surface of the water tank 1, so as to remove the scale attached to the inner surface of the water tank 1, thereby ensuring the long-term use stability of the device, and facilitating the cleaning of the inner surface of the water tank 1, thereby improving the convenience of use of the device.
[0025] Further as Figure 4 As shown, it is worth explaining in detail that a threaded hole 9 is provided at a position of the inner cavity surface of the water tank 1 near the side of the motor 5, and a threaded plug 8 is connected to the internal thread of the threaded hole 9. When the sleeve 23 and the cleaning sleeve 24 need to be replaced, the threaded plug 8 is rotated to separate the threaded plug 8 from the water tank 1 through the threaded structure, and then the sleeve 23 is pulled to the outside of the water tank 1 through the hole provided on one side surface of the sleeve 23, and then the replaced sleeve 23 and the cleaning sleeve 24 are extended to the inner cavity position of the water tank 1 by passing through the threaded hole 9, thereby ensuring the cleaning effect of the cleaning sleeve 24 during long-term use.
[0026] In summary: by starting the motor 5, the rotating shaft 4 can rotate, thereby the rotating disk 14 rotates, so that the movable rod 17 performs a circular motion while rotating itself, so that the cleaning sleeve 24 can gradually rub and clean the inner circumference of the water tank 1, so as to remove the scale attached to the inner circumference of the water tank 1, thereby ensuring the stability of the device during long-term use, and facilitating the cleaning of the inner circumference of the water tank 1, thereby improving the convenience of use of the device, and by rotating the threaded plug 8 when the sleeve 23 and the cleaning sleeve 24 need to be replaced, the threaded plug 8 is separated from the water tank 1 through the threaded structure, and then the sleeve 23 is pulled to the outside of the water tank 1 through the hole opened on one side surface of the sleeve 23, and then the replaced sleeve 23 and the cleaning sleeve 24 are extended to the inner cavity position of the water tank 1 through the threaded hole 9, thereby ensuring the cleaning effect of the cleaning sleeve 24 during long-term use.
[0027] The motor 5 can be purchased from the market. The motor 5 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
