[0035] Embodiment 2

[0036] Reference Figure 1 - Figure 6 , the present invention provides a new technical solution based on the first embodiment:

[0037] In the present invention, a second connecting pipe 18 is fixedly connected to the side of the tank body 1 away from the first connecting pipe 2, and the second connecting pipe 18 is fixedly connected to the diffusion pipe 6. The other end of the second connecting pipe 18 is fixedly connected to a buffer cylinder 19, and a piston 20 is slidably connected inside the buffer cylinder 19. A spring 21 is fixedly connected between the piston 20 and the inner wall of one end of the buffer cylinder 19, and the bottom of the buffer cylinder 19 is fixedly connected to an outlet pipe 15. When the impact force is large, the medium enters the buffer cylinder 19 through the second connecting pipe 18 and pushes the piston 20 to move. The piston 20 is supported by the spring 21, thereby reducing the impact force of the medium and improving the stability of medium diffusion.

[0038] In particular, the bottom of the curved pipe 3 is fixedly connected to an extension pipe 4, a filter cartridge 23 is inserted in the extension pipe 4, a slideway and a slide plate are provided between the filter cartridge 23 and the extension pipe 4 to prevent the filter cartridge 23 from rotating, a sealing cover 31 is fixedly connected to the bottom of the extension pipe 4, a support cylinder 32 for supporting the filter cartridge 23 is fixedly connected to the inner wall of one end of the sealing cover 31, the filter cartridge 23 extends into the curved pipe 3 to filter the incoming liquid, and when the medium passes through the curved pipe 3, the medium is filtered by the filter cartridge 23 in the extension pipe 4 to keep the cleanliness of the medium.

[0039] It should be noted that the bottom of the filter cartridge 23 is fixedly connected to a plurality of fixing rods 28, which are distributed in an annular manner. The bottom of the sealing cover 31 is fixedly connected to the fixing cylinder 24, and the bottom of the fixing cylinder 24 is fixedly installed with an air motor 25. An air inlet pipe 26 is provided on one side of the air motor 25, and the air inlet pipe 26 is fixedly connected to the air outlet pipe 15. One end of the output shaft of the air motor 25 is fixedly connected to a drive shaft 27, and one end of the drive shaft 27 passes through the sealing cover 31 and is fixedly connected to a rubber rod 29, which is connected to the plurality of fixing rods 28. When used in conjunction, the gas discharged from the air outlet pipe 15 enters the air motor 25 after passing through the one-way air outlet valve 16, thereby driving the output shaft of the air motor 25 to rotate, the air motor 25 drives the drive shaft 27 to rotate, and the drive shaft 27 drives the rubber rod 29 to rotate. The rubber rod 29 contacts one of the fixed rods 28 and then deforms. After then losing contact, the rubber rod 29 resets and collides with the other fixed rod 28, thereby causing the filter cartridge 23 to vibrate, facilitating the falling of impurities filtered by the filter cartridge 23, thereby improving the filtering effect of the filter cartridge 23.

[0040] In the present invention, a one-way air outlet valve 16 is installed on the circumference of the air outlet pipe 15, and a one-way air inlet valve 17 is fixedly installed at the bottom of the air outlet pipe 15. The one-way air inlet valve 17 is located between the one-way air outlet valve 16 and the buffer cylinder 19. The one-way air inlet valve 17 is used for air to enter the buffer cylinder 19.

[0041] In particular, pressure gauges 30 are fixedly installed on the circumference of the first connecting pipe 2 and the auxiliary pipe 12, and the pressure gauges 30 are convenient for people to observe.

[0042] It should be noted that a plurality of fixing columns 13 are fixedly connected to the circumferential inner wall of the hedge box 7 , and a plurality of clamps 14 are fixedly installed on the circumference of the diffuser 6 . The clamps 14 are fixed to the fixing columns 13 respectively, and the clamps 14 and the fixing columns 13 increase the stability of the diffuser 6 .

[0043] In the present invention, an inclined surface 22 is provided at one end of the diffuser tube 6, and the inclined surface 22 has an inclination angle of forty-five degrees.

[0044] In particular, the apertures of the first diffusion holes 9 and the second diffusion holes 10 are 15 mm to 30 mm respectively, and the spacing between adjacent first diffusion holes 9 and second diffusion holes 10 is 75 mm to 110 mm.

[0045] Working principle: When in use, the liquid enters the diffusion tube 6 through the elbow 3 and the first connecting tube 2, and diffuses the medium through the first diffusion hole 9 and the second diffusion hole 10 on the diffusion tube 6. At the same time, part of the medium enters the hedge box 7 through the auxiliary tube 12 and rushes out through the hedge hole 8. Since the hedge hole 8 corresponds to the first diffusion hole 9 and the second diffusion hole 10 respectively, the medium entering the tank body 1 is hedged, which effectively reduces the flow rate and kinetic energy of the oil entering the oil tank, thereby avoiding the impact force on the inner floating plate and the tank body 1, avoiding static electricity, and improving the storage safety and service life of the tank body 1;

[0046] After the medium rushes into the diffusion tube 6, when the impact force is large, the medium enters the buffer cylinder 19 through the second connecting tube 18, and at the same time pushes the piston 20 to move, and the piston 20 is supported by the spring 21, so as to reduce the impact force of the medium, improve the stability of the medium diffusion, and maintain the safety of the pipeline. At the same time, the gas when the piston 20 moves enters and exits through the outlet pipe 15;

[0047] When the medium passes through the bent pipe 3, the medium is filtered by the filter cartridge 23 in the extension pipe 4 to keep the cleanliness of the medium, and the gas discharged from the outlet pipe 15 enters the pneumatic motor 25 after passing through the one-way outlet valve 16, thereby driving the output shaft of the pneumatic motor 25 to rotate, and the pneumatic motor 25 drives the drive shaft 27 to rotate, and the drive shaft 27 drives the rubber rod 29 to rotate. The rubber rod 29 contacts one of the fixed rods 28 and then deforms. After then losing contact, the rubber rod 29 resets and collides with the other fixed rod 28, thereby causing the filter cartridge 23 to vibrate, facilitating the falling of impurities filtered by the filter cartridge 23, and improving the filtering effect of the filter cartridge 23.

[0048] However, as is well known to those skilled in the art, the working principle and wiring method of the pneumatic motor 25 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
