Description

Technical Field

[0001] This utility model relates to the technical field of compressor oil tank structure design. More specifically, this utility model relates to an oil tank with a baffle tube. Background Technology

[0002] The compressor's lubrication system mainly consists of a lubricating oil tank, oil pump, filter, cooler, piping, and lubricating oil. The lubricating oil tank stores the lubricating oil, while the oil pump draws the oil from the tank and delivers it to all lubrication points on the compressor. The filter removes impurities from the lubricating oil, preventing them from entering the compressor. The cooler lowers the temperature of the lubricating oil, ensuring its quality. The piping delivers the lubricating oil to each lubrication point, ensuring adequate lubrication for all parts of the compressor. The oil tank provides the compressor with a sufficient quantity and quality of lubricating oil, ensuring its normal operation.

[0003] Marine compressors need to operate at sea for extended periods. When ships sail on the sea, they are prone to tilting or rolling, and the lubricating oil in the oil tank can easily overflow from the tank's breather cap. Currently, the main solutions to this problem are to install additional buffer oil tanks, buffer oil pipes, or to install an electrically controlled gyroscope structure that balances the ship's movement. These structures are all large and complex, and there is currently a lack of simple and effective structural designs to prevent lubricating oil from overflowing during ship vibration. Summary of the Invention

[0004] The purpose of this invention is to provide an oil tank with a baffle tube to solve the technical problem that existing compressor oil tanks installed on ship hulls lack a simple and effective anti-vibration overflow design.

[0005] To achieve these objectives and other advantages according to this utility model, an oil tank with a baffle tube is provided, including a tank body. An oil inlet pipe is connected to one side of the lower end of the tank body, and an oil outlet pipe is connected to the other side. A baffle tube is connected to the top of the tank body and extends upward. Baffle plates are arranged vertically at intervals and cross each other inside the baffle tube. The outer ends of the baffle plates are arranged beyond the central axis inside the baffle tube. A layer of mesh is radially connected to the top of the baffle plates inside the baffle tube. A breather cap is detachably connected to the top of the baffle tube to balance the air pressure inside and outside the connected baffle tube and the tank body.

[0006] Preferably, the bottom of the box is symmetrically welded with mounting base plates, which are then fixedly connected to the hull.

[0007] Preferably, the baffle tube includes a housing, the baffle plate is fixedly connected to the inner wall of the housing, the partition mesh is detachably connected to the inner wall of the housing, the housing is integrally welded to the box body, and the oil inlet pipe and the oil outlet pipe are respectively welded and fixed to the box body.

[0008] Preferably, the upper end of the baffle tube is connected to the breathing cap by a thread.

[0009] Preferably, the lower outer side of the breathing cap is connected to the upper inner side of the shell by a thread. The structure of the mesh includes two layers of rubber rings, the outer diameter of which is matched with the inner diameter of the shell. A downwardly recessed arc-shaped grid is fixedly connected in the middle of the two rubber rings. A limit strip is connected to the inner wall of the shell below the two rubber rings. The top of the two rubber rings abuts against the bottom of the breathing cap screwed into the shell.

[0010] Preferably, the limiting strip is a minor arc-shaped line segment structure and is symmetrically arranged in the horizontal direction.

[0011] Preferably, each of the baffles is arranged facing the central axis of the baffle tube and inclined downwards.

[0012] Preferably, the lower outer wall of the baffle tube is provided with a ring of toothed plates extending downward and outward toward the inside of the box.

[0013] Preferably, the toothed plate includes uniformly spaced convex tooth structures, and the distance between adjacent convex tooth structures is less than the width of the convex tooth structure.

[0014] This utility model has at least the following beneficial effects: The oil tank with baffle tube of this utility model includes a tank body, a baffle tube, and a breather cap. The tank body is used to store lubricating oil. An oil inlet pipe is connected to one side of the lower end of the tank body, and an oil outlet pipe is connected to the other side. The top of the tank body is connected to the baffle tube. Baffle plates are arranged vertically at intervals and cross each other inside the baffle tube.

The overall structure is simple, easy to fix and install, and occupies little space. It is especially suitable for use with marine compressors.

[0015] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1-2 As shown, the oil tank with baffle tube of this utility model includes a tank body 3. An oil inlet pipe 5 is connected to one side of the lower end of the tank body 3, and an oil outlet pipe 6 is connected to the other side. A baffle tube 2 is connected to the top of the tank body 3. Baffle plates 7 are arranged vertically at intervals and cross each other inside the baffle tube 2. The outer end of the baffle plate 7 is set beyond the central axis inside the baffle tube 2. A layer of mesh 9 is radially connected to the top of the baffle plate 7 inside the baffle tube 2. A breather cap 1 is detachably connected to the top of the baffle tube 2 to balance the air pressure inside and outside the connected baffle tube 2 and tank body 3.

[0021] The oil tank is a container for storing lubricating oil in the compressor. The lubricating oil ensures the normal operation of the compressor. The oil tank draws in lubricating oil through the oil inlet pipe 5 and outputs lubricating oil through the oil return pipe to lubricate the compressor. The oil tank is connected to the atmosphere through the breather cap 1. The breather cap 1 can be a commercially available hydraulic oil tank breather cap with a G-thread rodless design to balance the internal and external air pressure. During the vibration of the hull, the lubricating oil in the oil tank is blocked and limited by the baffles 7 that are cross-set in the baffle tube 2. The baffles 7 do not affect the connection between the space inside the oil tank and the breather cap 1. Finally, a small amount is blocked by the mesh 9. The mesh of the mesh 9 should not be too small to prevent the lubricating oil from adhering and forming a film. By setting the baffle tube 2 section structure, the possibility of lubricating oil adhering to the lower inlet of the breather cap 1 can be reduced, which is conducive to ensuring the normal air pressure balance function of the breather cap 1. The oil tank with the baffle tube 2 has the function of storing lubricating oil and preventing lubricating oil from overflowing and polluting the environment during the vibration of the hull. The overall structure is simple, easy to fix and install, and occupies little space, making it particularly suitable for marine compressors.

[0022] In another technical solution, such as Figure 1 As shown, mounting base plates 4 are symmetrically welded to the bottom of the housing 3. The housing is fixedly connected to the hull through the mounting base plates 4, and the whole is firmly connected to the hull, ensuring the stability of the connection between the oil inlet pipe 5, the oil outlet pipe 6 and the other structures, as well as the operation of the compressor.

[0023] In another technical solution, such as Figure 1-2 As shown, the baffle tube 2 includes a housing 8, the baffle plate 7 is fixedly connected to the inner wall of the housing 8, the partition 9 is detachably connected to the inner wall of the housing 8, the housing 8 is integrally welded to the box body 3, the oil inlet pipe 5 and the oil outlet pipe 6 are respectively welded and fixed to the box body 3, and the baffle tube 2 is integrally connected to the top middle position of the oil tank box body 3, and is set slightly larger than the diameter of the oil inlet pipe 5 and the oil outlet pipe 6.

[0024] In another technical solution, such as Figure 1-2 As shown, the upper end of the baffle tube 2 is connected to the breathing cap 1 by a thread, and a sealing measure is set at the connection to improve the stability of the threaded connection.

[0025] In another technical solution, such as Figure 2 As shown, the lower outer side of the breathing cap 1 is connected to the upper inner side of the housing 8 by a thread. The structure of the mesh 9 includes two layers of rubber rings 10. The outer diameter of the rubber rings 10 is matched with the inner diameter of the housing 8. A downwardly recessed arc-shaped grid 11 is fixedly connected in the middle of the two layers of rubber rings 10. A limiting strip 12 is connected to the lower side of the two layers of rubber rings 10 on the inner wall of the housing 8. The top of the two layers of rubber rings 10 abuts against the bottom of the breathing cap 1 screwed into the housing 8.

[0026] The two rubber rings 10 are clamped together in the middle to fix the arc-shaped grid 11. The grid 11 can be made of stainless steel and forms a cone-shaped or spherical depression downwards, which separates the grid 11 from the bottom of the breather cap 1. At the same time, the downward-depressed part can change and guide the movement direction of the upward-vibrating splashed lubricating oil, which finally collects and drips from the lowest point of the depression. The two rubber rings 10 are pressed together by the bottom of the breather cap 1 screwed in by threads, which also serves to seal the threaded connection.

[0027] In another technical solution, such as Figure 2 As shown, the limiting strip 12 has a slightly curved line segment structure and is symmetrically arranged in the horizontal direction to facilitate the installation, removal and replacement of the rubber ring 10 structure and avoid dead angles.

[0028] In another technical solution, such as Figure 1-2As shown, each of the baffle plates 7 is oriented toward the central axis of the baffle tube 2 and is inclined downwards. In the radial plane, all the baffle plates 7 completely cover the lower port of the baffle tube 2. At the same time, the downward inclination can better prevent the lubricating oil from oscillating out of the baffle plates 7. A small amount of lubricating oil that oscillates and comes into contact with the upper side of the baffle plate 7 can be guided downwards along the inclination direction of the baffle plate 7 and flow back into the housing 3.

[0029] In another technical solution, such as Figure 2 As shown, a toothed plate 13 is provided on the lower outer wall of the baffle tube 2, which extends downward and outward toward the box 3. This further prevents the lubricating oil in the box 3 from entering the lower end of the baffle tube 2. The toothed plate 13 structure can avoid affecting the air pressure balance inside and outside the box 3.

[0030] In another technical solution, such as Figure 2 As shown, the toothed plate 13 includes a uniformly spaced convex tooth structure, and the distance between adjacent convex tooth structures is smaller than the width of the convex tooth structure, which improves the blocking effect on the lubricating oil vibration inside the housing 3.

[0031] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the drawings shown and described herein.
