Description

Technical Field

[0001] This invention belongs to the field of nitrogen tank auxiliary equipment, and particularly relates to a nitrogen tank cooling spray device. Background Technology

[0002] With the development of the times, the transportation industry is booming. As an important hub for waterway transportation, port enterprises are also bearing an increasingly heavy workload. Nitrogen is a commonly used storage and purging gas in port enterprises, and the demand for nitrogen at the port is very large. However, with the increase in workload, the number of nitrogen tanks at the port is insufficient. Port enterprises will pressurize the nitrogen supplied by the nitrogen source before storing it in the nitrogen tank. In order to improve the nitrogen storage efficiency, sometimes multiple pressurization components are turned on at the same time. This creates a new problem, that is, after multiple pressurization components compress nitrogen at the same time, the temperature of nitrogen will rise rapidly. Especially in hot weather, high temperature and high pressure nitrogen poses a significant safety hazard. Therefore, there is a need to provide a nitrogen tank spraying device that can uniformly cool the nitrogen tank when multiple pressurization components are operating at the same time. Summary of the Invention

[0003] The purpose of this invention is to provide a nitrogen tank cooling spray device to solve the problem that the temperature of nitrogen rises rapidly after compression, especially in hot weather. High temperature and high pressure nitrogen poses a significant safety hazard. Therefore, there is a need to provide a nitrogen tank spray device that can uniformly cool the nitrogen tank.

[0004] To achieve the above objectives, the specific technical solution of the present invention is as follows: A nitrogen tank cooling spray device is disclosed for cooling a nitrogen storage tank that is simultaneously pressurized by multiple pressurizing components. The device includes a base, a rotating disk, and an outer peripheral wall. The rotating disk is sleeved on the base and rotatably connected to it. The outer peripheral wall is rotatably connected to the rotating disk, and the connection between the outer peripheral wall and the rotating disk is sealed, forming a water storage cavity between them. A driving blade is provided on the side wall of the rotating disk within the water storage cavity. An elastic nozzle is movably disposed on the outer peripheral wall. As the rotating disk rotates, the driving blade strikes the end of the elastic nozzle that extends into the water storage cavity, causing the water outlet direction of the elastic nozzle to change after being struck by the driving blade. With this design, the device is fixed to the outer surface of the nitrogen tank. Water flow drives the rotating disk to rotate, and the driving blade of the rotating disk continuously strikes the elastic nozzle, causing the elastic nozzle to vibrate continuously and spray water evenly onto the nitrogen tank.

[0005] Furthermore, both the rotating disk and the base have arc-shaped grooves on their opposing surfaces, each groove enclosing a number of balls. The arc length of the arc-shaped groove is one-quarter of the circumference of the balls, and the balls are evenly held in the arc-shaped grooves by a retainer. This design reduces friction between the balls and the base during relative rotation, and the retainer evenly holds the balls around the arc-shaped grooves.

[0006] Furthermore, the base is hollow inside, and an opening is provided on the bottom surface of the base that fits against the nitrogen tank. A magnet of a suitable shape is installed inside the base, with some of the magnet protruding from the opening and coplanar with the bottom surface of the base. With this design, since the nitrogen tank is made of metal, the magnet can be directly attracted to it. Part of the magnet is enclosed within the base, while another part is exposed and can directly contact the nitrogen tank, strengthening the attraction force while pressing the base firmly onto the nitrogen tank.

[0007] Furthermore, the two ends of the rotating disk bulge outwards radially, forming a recess in the middle section. The drive paddles are arranged in a circumferential array in the recess, and the cross-sectional shape of the drive paddles along the axial direction of the rotating disk is an acute-angled triangle. The drive paddles are obliquely fixed to the rotating disk. With this design, the drive paddles can maintain a vertical position relative to the incoming water flow to the greatest extent possible, using the thrust of the water flow to drive the rotating disk to rotate.

[0008] Furthermore, the elastic nozzle includes a tube body and a spring. The diameter of the tube body is smaller than the mounting hole on the outer peripheral wall through which the tube body passes. Two protrusions are provided on the tube body, located on opposite sides of the outer peripheral wall. The spring provides elastic support between the protrusions located on the outer side of the outer peripheral wall and the outer peripheral wall. With this design, the tube body's diameter is smaller than the mounting hole, allowing for a certain degree of rotation. The spring's elastic support keeps the elastic nozzle stable under normal conditions. When the drive lever strikes the tube body, the water outlet angle of the elastic nozzle vibrates, thus uniformly spraying the nitrogen tank.

[0009] Furthermore, the protrusion on the inner side of the outer peripheral wall of the elastic nozzle is a spherical protrusion, and a spherical groove is formed at the part of the outer peripheral wall that abuts against the spherical protrusion. The shape of the spherical groove is adapted to the shape of the spherical protrusion. With this design, the elastic nozzle rotates more smoothly, and the adaptation relationship between the spherical groove and the spherical protrusion also allows the elastic nozzle to remain stable when it is not hit by the drive lever.

[0010] Furthermore, the rotating disk is rotatably connected to the outer peripheral wall via two large-diameter bearings, each mounted at one end of the rotating disk. This design allows the rotating disk and the outer peripheral wall to rotate relative to each other.

[0011] Furthermore, the large-diameter bearing also includes a sealing ring, which is fixedly installed on the outer ring of the large-diameter bearing. This design allows the sealing ring to maintain a certain degree of airtightness within the water storage chamber.

[0012] Furthermore, the outer peripheral wall is also provided with an inlet and an outlet. The diameter of the inlet is larger than that of the outlet. The water inlet's direction is coordinated with the drive lever to push the drive lever, thereby driving the rotating disk. With this design, the water flow drives the drive lever, which in turn drives the rotating disk to rotate.

[0013] The beneficial effects of this invention are as follows: This invention is fixed on the outer surface of the nitrogen tank, and the rotating disk is driven to rotate by the water flow. The driving paddle of the rotating disk continuously hits the elastic nozzle, causing the elastic nozzle to vibrate continuously and spray water evenly onto the nitrogen tank. The water evaporates and absorbs heat, reducing the temperature of the nitrogen tank. Attached Figure Description

[0015] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0016] like Figures 1 to 9 As shown.

[0017] Example 1

[0018] A nitrogen tank cooling spray device is used to cool a nitrogen storage tank that is simultaneously pressurized by multiple pressurizing components 23. The device includes a base 1, a rotating disk 2, and an outer peripheral wall 3. The rotating disk 2 is sleeved on the base 1 and rotatably connected to it. The outer peripheral wall 3 is rotatably connected to the rotating disk 2. The connection between the outer peripheral wall 3 and the rotating disk 2 is sealed, forming a water storage cavity 4 between them. A driving blade 5 is provided on the side wall of the rotating disk 2 within the water storage cavity 4. An elastic nozzle 6 is movably disposed on the outer peripheral wall 3. When the rotating disk 2 rotates, the driving blade 5 can strike the end of the elastic nozzle 6 that extends into the water storage cavity 4, causing the water outlet direction of the elastic nozzle 6 to change after being struck by the driving blade 5.

[0019] The above embodiment is implemented as follows: the pressurization component 23 is provided with multiple sets (including at least one set of conventional pressurization components, at least one set of standby pressurization components, and at least one set of auxiliary pressurization components). When the nitrogen storage tank needs to be replenished quickly, multiple sets of pressurization components 23 will be activated simultaneously. Under this condition, the pressurization component 23 will compress the nitrogen stored in the nitrogen tank and then store it in the nitrogen tank to increase the nitrogen storage capacity of the nitrogen tank. Since the volume of the nitrogen storage tank is fixed, but the nitrogen temperature will rise rapidly when the nitrogen is compressed; at the same time, if the external environment of the nitrogen storage tank is in a hot summer, the temperature rise of the nitrogen storage tank will cause great safety hazards, so it is necessary to cool down the nitrogen tank at this time.

[0020] Water flows into the water storage chamber 4 at an angle approximately 90° to the drive lever 5. The drive lever 5 is pushed by the water flow, causing the rotating disk 2 to rotate. As the end of the elastic nozzle 6 extends into the water storage chamber 4, the drive lever 5 will continuously collide with the elastic nozzle 6 while the rotating disk 2 is rotating. The elastic nozzle 6 will vibrate after being collided, causing the water outlet direction to change, thereby achieving the purpose of uniform spraying.

[0021] Example 2

[0022] The rotating disk 2 and the base 1 are fitted with arc-shaped grooves 7 on their opposite surfaces. The two arc-shaped grooves 7 enclose a number of balls 8. The arc length of the cross section of the arc-shaped groove 7 is one-quarter of the circumference of the balls 8. The balls 8 are evenly held on the arc-shaped grooves 7 by the retainer 9.

[0023] The base 1 is hollow inside, and an opening 11 is provided on the bottom surface of the base 1 that is in contact with the nitrogen tank. A magnet 10 with a matching shape is installed inside the base 1, and part of the magnet 10 protrudes from the opening 11 and is coplanar with the bottom surface of the base 1.

[0024] The two ends of the rotating disk 2 bulge outwards radially, forming a depression in the middle section. The drive paddles 5 are arranged in a circular array in the depression. The cross-sectional shape of the drive paddles 5 in the axial direction of the rotating disk 2 is an acute triangle. The drive paddles 5 are obliquely fixed on the rotating disk 2.

[0025] The above embodiment is implemented as follows: the two sides of the drive lever 5 have different functions. The side that interacts with the water flow of the inlet 21 is the thrust side, and the side that impacts the elastic nozzle 6 is the impact side.

[0026] Example 3

[0027] The elastic nozzle 6 includes a tube body 12 and a spring 13. The diameter of the tube body 12 is smaller than the mounting hole 14 on the outer peripheral wall 3 through which the tube body 12 passes. Two protrusions 15 are provided on the tube body 12. The two protrusions 15 are respectively located on both sides of the outer peripheral wall 3. The spring 13 is elastically supported between the protrusions 15 located on the outer side of the outer peripheral wall 3 and the outer peripheral wall 3.

[0028] The elastic nozzle 6 has a spherical protrusion 16 on the inner side of the outer peripheral wall 3. A ball groove 17 is provided at the part of the outer peripheral wall 3 that cooperates and abuts against the spherical protrusion 16. The shape of the ball groove 17 is adapted to the shape of the spherical protrusion 16.

[0029] The rotating disk 2 is rotatably connected to the outer peripheral wall 3 via large-diameter bearings 18. Two large-diameter bearings 18 are provided, and the two large-diameter bearings 18 are respectively installed at both ends of the rotating disk 2.

[0030] The large-diameter bearing 18 also includes a sealing ring 19, which is fixedly installed on the outer ring 20 of the large-diameter bearing 18.

[0031] The above embodiment is implemented as follows: the diameter of the tube body 12 is smaller than that of the mounting hole 14, so the tube body 12 can rotate to a certain extent. The elastic support of the spring 13 makes the elastic nozzle 6 stable and stationary under normal conditions. When the drive plate 5 hits the tube body 12, the water outlet angle of the elastic nozzle 6 vibrates. The design of the spherical boss 16 and the ball groove 17 also makes the rotational and static states of the elastic nozzle 6 more stable. With this design, when the cooling water in the water storage chamber 4 is sprayed out through the elastic nozzle 6, the angle of the water flow sprayed out by the elastic nozzle 6 changes due to the continuous impact of the drive plate 5 on the elastic nozzle 6. The area of ​​the water sprayed on the outer surface of the nitrogen storage tank is expanded, thereby improving the cooling effect of the nitrogen storage tank and accelerating the cooling speed of the nitrogen storage tank.

[0032] Example 4

[0033] The outer peripheral wall 3 is also provided with an inlet 21 and an outlet 22. The diameter of the inlet 21 is larger than that of the outlet 22. The water inlet 21 is in the direction of water inlet 21 and is coordinated with the drive lever 5 to drive the drive lever 5 and thus drive the rotating disk 2.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
