Description

Technical Field

[0001] The utility model relates to a pressurizing device, in particular to an oil storage and filling machine. Background Art

[0002] A filling machine is a device used to fill liquids such as lubricating oil and butter, and is usually used in scenarios such as automobile maintenance and industrial production. In industrial production, when the filling point is far away from the filling machine, such as in a filling environment such as a dock or mine, the filling machine does not have enough pressure to input the fluid into the filling point. Therefore, there is an urgent need for a device that can transport the fluid output by the filling machine to a distant filling point. Utility Model Content

[0003] The utility model aims to provide an oil storage and filling machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] The oil storage and filling machine comprises: an oil cylinder, a piston is arranged inside the oil cylinder, the piston can separate the inside of the oil cylinder into an upper cavity and a lower cavity in the up and down directions, the oil cylinder is provided with a feed port and a discharge port connected to the upper cavity; an oil filling pump, an access end of which is connected to an oil filling pipe, the oil filling pipe is connected to the lower cavity, and an oil filling interface is provided on the oil filling pipe.

[0006] The technical solution has at least the following beneficial effects: the oil filling interface is connected to an external filling machine through a pipeline, and the oil outlet end of the oil filling pump is connected to an external filling point through a pipeline. When in use, the filling machine inputs fluid from the oil filling interface into the oil filling pipe and flows into the lower cavity. The fluid fills the lower cavity, pushing the piston in the oil cylinder upward, reducing the space in the upper cavity, so that the gas or liquid in the upper cavity is discharged from the discharge port. After the fluid in the lower cavity reaches a certain height, the fluid is stopped from being input from the oil filling interface, and the fluid is pressurized and output outwardly through the oil filling pump. At the same time, the feed port can be connected to an external air pump or hydraulic pump, and the air pump or hydraulic pump pushes the piston downward to assist the fluid in being pressurized and output outwardly. In this way, the fluid output by the filling machine can be transported to a farther filling point by temporarily storing the fluid in transit and then pressurizing it for delivery, thereby realizing long-distance filling and improving the control accuracy of the filling amount.

[0007] As a further improvement of the above technical solution, the feed port is used to input gas, and the discharge port is used to discharge the gas in the upper cavity. The upper cavity is pressurized or depressurized by gas. Specifically, when the piston moves upward, the gas in the upper cavity is discharged outward from the discharge port. When the fluid in the lower cavity needs to be discharged, compressed gas is introduced from the feed port to push the piston downward.

[0008] As a further improvement of the above technical solution, a magnetic strip is connected to the piston, and a magnetic sensor is arranged on the outside of the oil cylinder. When the piston moves up and down, the magnetic strip is also driven to move up and down. When passing through the magnetic sensor, the magnetic sensor can sense the magnetic strip and send a signal, so as to facilitate the piston position.

[0009] As a further improvement of the above technical solution, a plurality of magnetic sensors are arranged at intervals along the vertical direction. There are a plurality of magnetic sensors arranged, so as to conveniently know whether the piston is in a high position or a low position.

[0010] As a further improvement of the above technical solution, a switch valve is provided on the oil filling interface. When the filling machine delivers oil to the oil filling interface through the pipeline, the switch valve on the oil filling interface is opened, and when the fluid needs to be output from the oil filling pump, the switch valve on the oil filling interface is closed.

[0011] As a further improvement of the above technical solution, a plurality of sealing rings are sleeved on the outer side of the piston at intervals in the vertical direction. The piston abuts against the inner wall of the oil cylinder through the plurality of sealing rings on the outer side, which can more effectively separate the internal space of the piston in the vertical direction and improve the sealing performance of the upper cavity and the lower cavity.

[0012] As a further improvement of the above technical solution, the outer side of the piston is provided with a plurality of annular sealing grooves at intervals along the up-down direction, and the plurality of sealing rings are respectively sleeved in the plurality of annular sealing grooves. The plurality of sealing rings can be limited by the plurality of annular sealing grooves on the outer side of the piston, effectively reducing the displacement of the sealing rings relative to the piston, and preventing the sealing rings from falling out when the piston moves up and down.

[0013] As a further improvement of the above technical solution, the piston includes a plurality of mutually stacked connection disks, an annular step is provided on the outer side of the connection disk, the annular step forms the annular sealing groove, and a connecting screw is inserted and connected in the middle of the plurality of connection disks. The piston is composed of a plurality of mutually stacked connection disks, and the sealing ring can be quickly pre-positioned by using the annular step on the outer side of the connection disk, and the adjacent connection disks can form an annular sealing groove at the position of the annular step to limit the sealing ring from axially escaping, and finally the connecting screw is inserted in the middle of the plurality of connection disks to connect and fix the plurality of connection disks.

[0017] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them.

In addition, all the connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0018] Reference Figure 1 The oil storage and filling machine comprises: an oil cylinder 100, in which a piston 110 is arranged, and the piston 110 can separate the interior of the oil cylinder 100 into an upper cavity and a lower cavity along the up and down directions, and the oil cylinder 100 is provided with a feed port 114 and a discharge port 115 connected to the upper cavity; an oil filling pump 200, the access end of which is connected to an oil filling pipe 210, and the oil filling pipe 210 is connected to the lower cavity, and an oil filling interface 211 is provided on the oil filling pipe 210.

[0019] In this oil storage filling machine, the filling interface 211 is connected to the external filling machine through a pipeline, and the oil outlet end of the filling pump 200 is connected to the external filling point through a pipeline. When in use, the filling machine inputs the fluid from the filling interface 211 into the filling pipe 210 and flows into the lower cavity. The fluid fills the lower cavity and pushes the piston 110 in the oil cylinder 100 upward. The space in the upper cavity is reduced, so that the gas or liquid in the upper cavity is discharged from the discharge port 115, and the lower cavity is filled with the fluid. After the fluid in the body reaches a certain height, stop inputting the fluid from the oil filling interface 211, and the fluid is pressurized and output outward through the oil filling pump 200. At the same time, the feed port 114 can be connected to an external air pump or hydraulic pump, and the air pump or hydraulic pump pushes the piston 110 downward to assist the fluid in being pressurized and output outward. In this way, the fluid output by the filling machine can be transported to a farther filling point by temporarily storing the fluid in transit and then pressurizing it for delivery, thereby realizing long-distance filling and improving the control accuracy of the filling amount.

[0020] Gas or liquid can be input into the upper cavity from the feed port 114 for pressurization to assist the piston 110 in discharging the fluid downward. In order to reduce interference with the fluid, in this embodiment, the feed port 114 is used to input gas, and the discharge port 115 is used to discharge the gas in the upper cavity. The upper cavity is pressurized or depressurized by gas. Specifically, when the piston 110 moves upward, the gas in the upper cavity is discharged outward from the discharge port 115. When the fluid in the lower cavity needs to be discharged, compressed gas is introduced from the feed port 114 to push the piston 110 downward.

[0021] In order to conveniently know the amount of fluid in the oil cylinder 100, in this embodiment, a magnetic strip 111 is connected to the piston 110, and a magnetic sensor 113 is arranged outside the oil cylinder 100. When the piston 110 moves up and down, the magnetic strip 111 is also driven to move up and down, and when passing through the magnetic sensor 113, the magnetic sensor 113 can sense the magnetic strip 111 and send a signal, so that the position of the piston 110 can be conveniently known.

[0022] In some embodiments, a plurality of magnetic sensors 113 are arranged at intervals along the vertical direction. For example, one magnetic sensor 113 can be installed at a low position outside the oil cylinder 100, and another magnetic sensor 113 can be installed at a high position outside the oil cylinder 100. There are a plurality of magnetic sensors 113 arranged, so that it is convenient to know whether the piston 110 is at a high position or a low position.

[0023] In some embodiments, a switch valve is provided on the oil filling interface 211. When the filling machine delivers oil to the oil filling interface 211 through the pipeline, the switch valve on the oil filling interface 211 is opened, and when the fluid needs to be output from the oil filling pump 200 to the outside, the switch valve on the oil filling interface 211 is closed.

[0024] The piston 110 can be made of an elastic material directly, or a structure with a rigid material inside and an elastic material outside. Specifically, a plurality of sealing rings 112 are sleeved on the outside of the piston 110 at intervals along the vertical direction. The piston 110 is pressed against the inner wall of the oil cylinder 100 through the plurality of sealing rings 112 on the outside, which can more effectively separate the internal space of the piston 110 along the vertical direction, thereby improving the sealing performance of the upper cavity and the lower cavity.

[0025] The sealing ring 112 can be directly sleeved on the outside of the piston 110. When the piston 110 moves up and down, the sealing ring 112 is easy to fall off from the piston 110. Therefore, a plurality of annular sealing grooves are arranged at intervals along the up and down directions on the outside of the piston 110, and the plurality of sealing rings 112 are respectively sleeved in the plurality of annular sealing grooves. The plurality of sealing rings 112 can be limited by the plurality of annular sealing grooves on the outside of the piston 110, effectively reducing the displacement of the sealing rings 112 relative to the piston 110, and preventing the sealing rings 112 from falling off when the piston 110 moves up and down.

[0026] If the elastic sealing ring 112 is directly expanded and deformed and then inserted into the annular sealing groove on the outside of the piston 110, the assembly is difficult. Therefore, the piston 110 can be disassembled into multiple module structures and then assembled. In this embodiment, the piston 110 includes multiple connecting disks stacked on each other, and an annular step is provided on the outside of the connecting disk, and the annular step forms the annular sealing groove. The middle of the multiple connecting disks is inserted and connected with a connecting screw. The piston 110 is composed of multiple connecting disks stacked on each other. The annular step on the outside of the connecting disk can be used to quickly pre-position the sealing ring 112, and the adjacent connecting disks can form an annular sealing groove at the position of the annular step to limit the sealing ring 112 from axially disengaging. Finally, the connecting screw is inserted in the middle of the multiple connecting disks to connect and fix the multiple connecting disks.

[0027] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
