Description

Technical Field

[0001] This utility model relates to the field of oil-water filtration technology, and in particular to an oil-water filtration device for gas stations. Background Technology

[0002] Gas station oil-water filtration systems utilize principles such as gravity, filtration, centrifugation, and coalescence to separate oil and water. They consist of a filtration section (including filter screens and filter elements), a separation section (such as an oil separator or grease trap), and auxiliary components (pumps, valves, etc.). Common types include gravity-type, centrifugal-type, and membrane-type systems. Regular inspection of all components is necessary, including cleaning or replacing filter screens and filter elements, and checking for leaks, to ensure proper operation and effective separation.

[0003] Currently, most gas station oil-water filtration devices are connected to the storage tanks containing the oil-water mixture via flanges. While this method is relatively simple to operate, it involves numerous bolts, making installation and disassembly time-consuming and resulting in low installation efficiency. Furthermore, the two flanges are mostly sealed with gaskets. Although gaskets are inexpensive, they may deform over time, failing to fit tightly against the flange surface and affecting the sealing effect. Therefore, this application proposes an oil-water filtration device for gas stations to meet this requirement. Utility Model Content

[0004] In order to overcome the shortcomings of low connection efficiency between existing devices and storage tanks and poor sealing effect of gaskets, this utility model provides an oil-water filtration device for gas stations.

[0005] The technical implementation scheme of this utility model is as follows: an oil-water filtration device for gas stations, including a filter tank, an inlet pipe installed on the top of one side of the filter tank, a connecting pipe connected to a storage tank on one side of the inlet pipe, a first connecting seat and a second connecting seat fixedly connected to one end of the inlet pipe and the connecting pipe respectively, a connecting component and a sealing component provided at the connection between the first connecting seat and the second connecting seat, an oil drain pipe installed on the top of the other side of the filter tank, and a drain pipe installed at the bottom of the other side of the filter tank.

[0006] Optionally, the connecting assembly includes a mounting groove, a mounting block, a mounting hole, a first connecting groove, and a mounting rod. The mounting groove is formed on one side surface of the second connecting seat. The mounting block is fixedly connected to one side surface of the second connecting seat and is adapted to the size of the mounting groove. The mounting hole passes through the mounting block. The first connecting groove is formed on one side inner wall of the mounting groove. The mounting rod is movably connected to the first connecting groove and is adapted to the size of the mounting hole.

[0007] Optionally, the connecting assembly further includes a rotating groove, a rotating ring, and a first connecting block. The rotating groove is formed inside the first connecting seat and communicates with the bottom of the first connecting groove. The rotating ring is rotatably connected to the rotating groove. The first connecting block is movably connected to the first connecting groove and its two ends are respectively fixedly connected to the mounting rod and the rotating ring.

[0008] Optionally, the connecting assembly further includes a slide groove, a slider, and a spring. The slide groove is formed on the other side surface of the first connecting seat and communicates with the rotating groove. The slider is fixedly connected to the rotating ring and slidably connected to the slide groove. The spring is installed inside the slide groove and its two ends are respectively fixedly connected to one side of the slider and one side of the inner wall of the slide groove.

[0009] Optionally, the sealing assembly includes a sealing groove, an annular groove, and a sealing ring. The sealing groove is formed on one side surface of the second connecting seat, the annular groove is formed on one side surface of the first connecting seat, the sealing ring is installed inside the annular groove and, after expansion, adapts to the size of the sealing groove, and the sealing ring is made of rubber and is hollow inside.

[0010] Optionally, the sealing assembly further includes an air chamber, a piston, and a connecting hole. The air chamber is located inside the first connecting seat, the piston is slidably connected to the air chamber and is sized to match it, and the connecting hole is located on the inner wall of one end of the air chamber and communicates with the sealing ring.

[0011] Optionally, the sealing assembly further includes a second connecting groove, a second connecting block, and a connecting rod. The second connecting groove is formed on the inner wall of the bottom of the slide groove and communicates with the air chamber. The second connecting block is movably connected to the second connecting groove and fixedly connected to the bottom of the slider. The connecting rod is movably connected to the air chamber and the second connecting groove and its two ends are respectively fixedly connected to the second connecting block and the piston.

[0012] This utility model has the following advantages:

[0013] 1. This utility model features an installation assembly. A sliding block along a groove compresses a spring. During this process, a rotating ring moves synchronously along the groove with the sliding block. The rotating ring, via a first connecting block, drives an installation rod to move synchronously within the first connecting groove. When the installation rod moves out of the groove and into the first connecting groove, the installation block of the second connecting seat is placed in the installation groove of the first connecting seat, aligning the installation hole with the installation rod. The sliding block is then released, causing the spring to rebound and drive the rotating ring to move in the opposite direction. At this point, the first connecting block moves the installation rod into the installation groove. When the installation rod is inserted into the installation hole, the installation block is fixed in the installation groove, thus completing the installation of the first and second connecting seats. This design simplifies and speeds up the connection between the inlet pipe and the connecting pipe, thereby improving installation efficiency.

[0014] 2. This utility model incorporates a sealing component. During the process of the slider compressing the spring, the rotating ring drives the piston to move synchronously within the air chamber via the second connecting block and the connecting rod, drawing air from the sealing ring into the air chamber through the connecting hole. When the sealing ring deflates and is submerged in the annular groove, the first and second connecting seats are connected. After the connection is complete, the spring rebounds and drives the slider to move in the opposite direction. At this time, the second connecting block drives the piston to move in the opposite direction along the air chamber via the connecting rod, sending air from the air chamber into the sealing ring. When the sealing ring expands to fit tightly against the sealing groove, the connection between the first and second connecting seats is sealed. Compared to a sealing gasket, this design effectively enhances the sealing performance between the water inlet pipe and the connecting pipe, thereby preventing leakage at the connection.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] An oil-water filtration device for gas stations includes a filter tank 1. A water inlet pipe 2 is installed on the top of one side of the filter tank 1. A connecting pipe 3 connected to a storage tank is provided on one side of the water inlet pipe 2. A first connecting seat 4 and a second connecting seat 5 are fixedly connected to one end of the water inlet pipe 2 and the connecting pipe 3, respectively. A connecting component 6 and a sealing component 7 are provided at the connection between the first connecting seat 4 and the second connecting seat 5. An oil drain pipe 8 is installed on the top of the other side of the filter tank 1, and a drain pipe 9 is installed at the bottom of the other side of the filter tank 1.

[0024] It should be noted that the connecting component 6 makes the connection and disassembly between the water inlet pipe 2 and the connecting pipe 3 simpler and faster, thereby improving assembly efficiency. The sealing component 7 can effectively enhance the sealing of the connection between the water inlet pipe 2 and the connecting pipe 3, thereby preventing leakage at the connection.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the connecting component 6 includes a mounting groove 61, a mounting block 62, a mounting hole 63, a first connecting groove 64, and a mounting rod 65. The mounting groove 61 is formed on one side surface of the second connecting seat 5. The mounting block 62 is fixedly connected to one side surface of the second connecting seat 5 and is adapted to the size of the mounting groove 61. The mounting hole 63 passes through the mounting block 62. The first connecting groove 64 is formed on one side inner wall of the mounting groove 61. The mounting rod 65 is movably connected to the first connecting groove 64 and is adapted to the size of the mounting hole 63.

[0026] It should be noted that the mounting block 62 is placed in the mounting groove 61, and then the mounting rod 65 is slid along the first connecting groove 64. When the mounting rod 65 is inserted into the mounting hole 63, the mounting block 62 can be fixed in the mounting groove 61, thereby completing the connection between the first connecting seat 4 and the second connecting seat 5.

[0027] like Figure 4 As shown, the connecting component 6 also includes a rotating groove 66, a rotating ring 67, and a first connecting block 68. The rotating groove 66 is opened inside the first connecting seat 4 and is connected to the bottom of the first connecting groove 64. The rotating ring 67 is rotatably connected to the rotating groove 66. The first connecting block 68 is movably connected to the first connecting groove 64 and its two ends are respectively fixedly connected to the mounting rod 65 and the rotating ring 67.

[0028] It should be noted that rotating the rotating ring 67 along the rotating groove 66 can drive the mounting rod 65 to move synchronously within the first connecting groove 64 via the first connecting block 68.

[0029] like Figure 5 As shown, the connecting assembly 6 also includes a slide groove 69, a slider 610 and a spring 611. The slide groove 69 is opened on the other side surface of the first connecting seat 4 and is connected to the rotating groove 66. The slider 610 is fixedly connected to the rotating ring 67 and slidably connected to the slide groove 69. The spring 611 is installed inside the slide groove 69 and its two ends are fixedly connected to one side of the slider 610 and the inner wall of one side of the slide groove 69, respectively.

[0030] It should be noted that when the slider 610 is slid along the groove 69 to compress the spring 611, the rotating ring 67 will move synchronously along the rotating groove 66 with the slider 610. When the slider 610 is released, the spring 611 will rebound and drive the rotating ring 67 to move in the opposite direction through the slider 610.

[0031] like Figure 2 and Figure 3 As shown, the sealing assembly 7 includes a sealing groove 71, an annular groove 72, and a sealing ring 73. The sealing groove 71 is formed on one side surface of the second connecting seat 5, and the annular groove 72 is formed on one side surface of the first connecting seat 4. The sealing ring 73 is installed inside the annular groove 72 and, after expansion, matches the size of the sealing groove 71. The sealing ring 73 is made of rubber and is hollow inside.

[0032] It should be noted that after the first connecting seat 4 and the second connecting seat 5 are connected, air is injected into the sealing ring 73 to make it expand. When the sealing ring 73 expands to fit tightly with the sealing groove 71, the connection between the first connecting seat 4 and the second connecting seat 5 can be sealed.

[0033] like Figure 6 As shown, the sealing assembly 7 also includes an air chamber 74, a piston 75, and a connecting hole 76. The air chamber 74 is located inside the first connecting seat 4. The piston 75 is slidably connected to the air chamber 74 and is sized to match it. The connecting hole 76 is located on the inner wall of one end of the air chamber 74 and is connected to the sealing ring 73.

[0034] It should be noted that by sliding the piston 75 along the air chamber 74, air in the air chamber 74 can be sent to the sealing ring 73 through the connecting hole 76, or air in the sealing ring 73 can be drawn into the air chamber 74.

[0035] like Figure 6 As shown, the sealing assembly 7 also includes a second connecting groove 77, a second connecting block 78, and a connecting rod 79. The second connecting groove 77 is opened on the inner wall of the bottom of the slide groove 69 and communicates with the air chamber 74. The second connecting block 78 is movably connected to the second connecting groove 77 and fixedly connected to the bottom of the slider 610. The connecting rod 79 is movably connected to the air chamber 74 and the second connecting groove 77 and its two ends are fixedly connected to the second connecting block 78 and the piston 75, respectively.

[0036] It should be noted that during the sliding of slider 610 along slide groove 69, piston 75 will move synchronously in air chamber 74 through second connecting block 78 and connecting rod 79.

[0037] In a specific application scenario, the slider 610 first slides along the groove 69 to compress the spring 611. During this process, the rotating ring 67 moves synchronously along the rotating groove 66 with the slider 610. The rotating ring 67 then drives the mounting rod 65 to move synchronously in the first connecting groove 64 via the first connecting block 68. At the same time, the rotating ring 67 drives the piston 75 to move synchronously in the air chamber 74 via the second connecting block 78 and the connecting rod 79, drawing the air in the sealing ring 73 into the air chamber 74 through the connecting hole 76. When the mounting rod 65 moves out of the mounting groove 61 and into the first connecting groove 64, and the sealing ring 73 deflates until it is submerged in the annular groove 72, the mounting block 62 of the second connecting seat 5 is placed in the mounting groove 61 of the first connecting seat 4, aligning the mounting hole 63 with the mounting rod 65. Then, the slider 610 is released, the spring 611 rebounds, and the slider 610 drives the rotating ring 67 to move in the opposite direction. At this time, the first connecting block 68 drives the mounting rod 65 to move towards the mounting groove 64. The mounting rod 65 moves within the mounting groove 61. When it is inserted into the mounting hole 63, the mounting block 62 is fixed in the mounting groove 61, thus completing the installation of the first connecting seat 4 and the second connecting seat 5. At the same time, the second connecting block 78 drives the piston 75 to move in the opposite direction along the air chamber 74 through the connecting rod 79, and sends the air in the air chamber 74 to the sealing ring 73. When the sealing ring 73 expands to fit tightly with the sealing groove 71, the connection between the first connecting seat 4 and the second connecting seat 5 is sealed. Then, oil and water are added to the filter tank 1 through the connecting pipe 3 and the water inlet pipe 2 to start the filtration work. The filtered oil can be discharged from the oil drain pipe 8, and the filtered water can be discharged from the drain pipe 9. When it is necessary to remove the filter tank 1, slide the slider 610 along the sliding groove 69 again to move the mounting rod 65 out of the mounting hole 63 and make the sealing ring 73 deflate. Then, the mounting block 62 is removed from the mounting groove 61 to complete the disassembly of the first connecting seat 4 and the second connecting seat 5.
