The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 6 , which is the first embodiment of the utility model, and this embodiment provides an oil-water separator for compressible oil residue. The oil-water separator for compressible oil residue includes a main component 100 and a compression component 200. The two can cooperate to compress the oil residue after separating the oil and water, and the compressed oil residue can be collected.

[0030] The main component 100 includes an oil-water separator 101, a filter frame 102, an oil inlet 103, an oil outlet 104 and a water outlet 105. The filter frame 102 is located in the oil-water separator 101, the oil inlet 103 is arranged on one side of the filter frame 102, the oil outlet 104 is fixed on one side of the oil-water separator 101, and the water outlet 105 is fixed on one end of the oil-water separator 101.

[0031] The oil-water separator 101 is a device for separating a liquid mixed with oil and water. The filter frame 102 is used to filter the liquid entering the oil-water separator 101, remove impurities and solid particles therein, ensure the smooth progress of the separation process, and protect the equipment from damage. The oil inlet 103 is an inlet for inputting the liquid mixed with oil and water into the oil-water separator 101, and the raw liquid is introduced into the oil-water separator 101 through the oil inlet 103 for separation treatment. The oil outlet 104 is an outlet for taking out the separated oil substances from the oil-water separator 101. After the separation treatment, the oil substances will flow out from the oil outlet 104, which is convenient for collection and subsequent utilization. The water outlet 105 is an outlet for taking out the separated water substances from the oil-water separator 101. After the separation treatment, the water substances will flow out from the water outlet, which is convenient for discharge or further treatment.

[0032] The compression assembly 200 is arranged on the oil-water separator 101, and includes a compression member 201, a sealing member 202 and a trigger member 203. The compression member 201 is arranged on the top of the oil-water separator 101, the sealing member 202 is arranged on the filter frame 102, and the trigger member 203 is located on the compression member 201.

[0033] After using the oil-water separator 101 to separate the oil and water, the compression member 201 can be used to compress the oil residue remaining in the filter frame 102. By compressing the oil residue, the spillage and dispersion of the oil residue can be reduced, and the risk of environmental pollution can be reduced, which is beneficial to protecting the environment and the ecosystem. When compressing the oil residue remaining in the filter frame 102, the compression member 201 can be supported by the sealing member 202 so that the compression member 201 can compress the oil residue. After the compression of the oil residue is completed, the compression member 201 will rise. At this time, the rise of the compression member 201 can make the trigger member 203 drive the sealing member 202 to move, and the compressed oil residue is discharged from the filter frame 102. When the compression member 201 is pressed down, the trigger member 203 will not drive the sealing member 202 to move.

[0034] Example 2

[0035] Reference Figure 1 to Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the compression member 201 includes a compression plate 201a and a cylinder 201b. The compression plate 201a is disposed on the top of the filter frame 102, and the cylinder 201b is fixed on the top of the compression plate 201a.

[0037] When the oil residue in the filter frame 102 needs to be compressed, the cylinder 201b is started, and the movement of the cylinder 201b drives the compression plate 201a to move. At this time, the compression plate 201a moves in the filter frame 102, so that the oil residue in the filter frame 102 can be compressed.

[0038] Specifically, the compression member 201 further includes a positioning plate 201c and a support frame 201d. The positioning plate 201c is fixed to one side of the cylinder 201b, and the support frame 201d is fixed to the top of the oil-water separator 101.

[0039] The positioning plate 201c is fixed to the inner wall of the support frame 201d. The positioning plate 201c is used to support the cylinder 201b to prevent the cylinder 201b from deflecting. The support frame 201d is used to protect the cylinder 201b to prevent the cylinder 201b from being hit by external debris and causing damage.

[0040] Specifically, the closing member 202 includes a closing door 202a, a first rotating shaft 202b and a first torsion spring 202c. The closing door 202a is located at the bottom of the filter frame 102, the first rotating shaft 202b is fixed to one side of the closing door 202a, the first rotating shaft 202b is plugged into one side of the filter frame 102, the first rotating shaft 202b and the filter frame 102 are movably connected, one end of the first torsion spring 202c is fixed to one side of the closing door 202a, and the other end is fixed to one side of the first rotating shaft 202b.

[0041] After the oil is guided into the filter frame 102, the setting of the closed door 202a can prevent the oil from leaking from the bottom of the filter frame 102. A sealing ring is provided on the outer side of the closed door 202a to improve the sealing performance. When the residue in the filter frame 102 is compressed, the closed door 202a can also support the compression plate 201a so that the compression plate 201a can compress the residue in the filter frame 102. After the oil residue is compressed, the compression plate 201a will rise, and the compression plate 201a will close the closed door 202a when it rises. The closing of the closed door 202a can rotate the first rotating shaft 202b, and the first rotating shaft 202b can apply a torsional force to the first torsion spring 202c by rotating. After the oil residue is compressed, the closed door 202a needs to be opened, and the closed door 202a can be opened by the rotation force of the first torsion spring 202c.

[0042] Specifically, the closing member 202 further includes a locking rod 202d and a locking block 202e. The locking rod 202d is fixed to one side of the closing door 202a, and the locking block 202e is arranged on one side of the locking rod 202d.

[0043] A lock groove corresponding to the lock rod 202d is provided on the lock block 202e. After the closed door 202a is closed, the lock rod 202d will be engaged with the lock rod 202d, and the closed door 202a can be limited. When it is necessary to release the limit of the closed door 202a, the lock block 202e is moved to separate the lock block 202e from the lock rod 202d. At this time, the closed door 202a can be opened by the rotation force of the first torsion spring 202c.

[0044] Specifically, the closing member 202 also includes a second rotating shaft 202f, a second torsion spring 202g and a fixed plate 202h. The second rotating shaft 202f is inserted into one side of the locking block 202e, and the fixed plate 202h is sleeved on the outside of the second rotating shaft 202f. The fixed plate 202h is movably connected to the second rotating shaft 202f. One end of the second torsion spring 202g is fixed to one side of the second rotating shaft 202f, and the other end is fixed to one side of the fixed plate 202h.

[0045] When the second rotating shaft 202f rotates, the locking block 202e can be rotated, and when the locking block 202e rotates, a torsional force can be applied to the second torsion spring 202g. After the locking block 202e rotates and separates from the locking rod 202d, the rotational force of the second torsion spring 202g can return the locking block 202e to its original position for next use. There are two fixed plates 202h, both of which are fixed to one side of the filter frame 102. The second rotating shaft 202f can be supported by the setting of the fixed plate 202h to prevent the second rotating shaft 202f from deviating.

[0046] Specifically, the closure member 202 further includes a driving block 202i, a shift plate 202j and a stopper 202k. The driving block 202i is fixed to one end of the second rotating shaft 202f. The shift plate 202j is hinged to one side of the driving block 202i. The stopper 202k is fixed to the top of the driving block 202i.

[0047] When the compression plate 201a compresses the oil residue, the compression plate 201a will be pressed down, and the compression plate 201a will squeeze the paddle plate 202j when pressing down. At this time, the paddle plate 202j will move, thereby not driving the second rotating shaft 202f to rotate. After the compression of the oil residue is completed, the compression plate 201a rises, and the compression plate 201a will squeeze the paddle plate 202j when rising. At this time, the paddle plate 202j will be limited by the setting of the stopper 202k, so that the paddle plate 202j can be moved. The paddle plate 202j will drive the driving block 202i to rotate by moving, and the second rotating shaft 202f can be driven to rotate by the rotation of the driving block 202i.

[0048] Example 3

[0049] Reference Figure 2 to Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0050] Specifically, the closing member 202 also includes a third rotating shaft 202l and a third torsion spring 202m. The third rotating shaft 202l is fixed to one side of the dial plate 202j. The third rotating shaft 202l is plugged into one side of the driving block 202i. The third rotating shaft 202l and the driving block 202i are movably connected. One end of the third torsion spring 202m is fixed to one side of the driving block 202i, and the other end is fixed to one side of the third rotating shaft 202l.

[0051] When the paddle plate 202j moves, it will drive the third rotating shaft 202l to rotate. The rotation of the third rotating shaft 202l can apply a torsional force to the third torsion spring 202m. The movement of the paddle plate 202j will not drive the second rotating shaft 202f to rotate. Then, the rotation force of the third torsion spring 202m will drive the paddle plate 202j to return to its original position. Then, the compression plate 201a can squeeze the paddle plate 202j again when it rises.

[0052] Specifically, the trigger member 203 includes a pressing block 203a and a first moving rod 203b. The pressing block 203a is arranged above the dial plate 202j. One end of the first moving rod 203b is fixed to the top of the dial plate 202j, and the other end is fixed to the top of the compression plate 201a.

[0053] When the compression plate 201a moves, it will drive the first moving rod 203b to move. The movement of the first moving rod 203b will drive the pressing block 203a to move. At this time, the movement of the pressing block 203a can squeeze the prying plate 202j.

[0054] Specifically, the trigger member 203 also includes a driving plate 203c, a second moving rod 203d and a baffle 203e. The driving plate 203c is located below the closed door 202a. One end of the second moving rod 203d is fixed to the top of the driving plate 203c, and the other end is fixed to the top of the compression plate 201a. The baffle 203e is fixed to one side of the filter frame 102.

[0055] When the compression plate 201a moves, it will drive the second moving rod 203d to move. The movement of the second moving rod 203d will drive the driving plate 203c to move. The movement of the driving plate 203c can squeeze the closed door 202a, so that the closed door 202a can be closed. The closed door 202a can be limited by the setting of the baffle 203e, so that the closed door 202a opens in an inclined state, so that the compressed oil residue can be guided to enter the designated container, and it is convenient for the driving plate 203c to squeeze the closed door 202a.

[0056] During use, when it is necessary to squeeze the oil residue, first start the cylinder 201b. The movement of the cylinder 201b will drive the compression plate 201a to move. When the compression plate 201a moves, it will drive the first moving rod 203b to move. The movement of the first moving rod 203b will drive the pressing block 203a to move. At this time, the movement of the pressing block 203a can squeeze the paddle plate 202j. When the paddle plate 202j moves, it will drive the third rotating shaft 202l to rotate. The rotation of the third rotating shaft 202l can apply a torsional force to the third torsion spring 202m. The movement of the paddle plate 202j will not drive the second rotating shaft 202f to rotate, and then the rotation force of the third torsion spring 202m will drive the paddle plate 202j to return to its original position.

[0057] After the oil residue is compressed, the compression plate 201a will rise. When the compression plate 201a rises, it will drive the pressing block 203a to squeeze the paddle plate 202j. At this time, the paddle plate 202j will be limited by the setting of the stopper 202k, so that the paddle plate 202j can move. The paddle plate 202j will drive the driving block 202i to rotate through the movement. The rotation of the driving block 202i can drive the second rotating shaft 202f to rotate. When the second rotating shaft 202f rotates, the locking block 202e can be rotated. When the locking block 202e rotates, a torsional force can be applied to the second torsion spring 202g. The locking block 202e moves and separates from the locking rod 202d. At this time, the closed door 202a can be opened by the rotation force of the first torsion spring 202c. At this time, the closed door 202a can be limited by the setting of the baffle plate 203e, so that the closed door 202a opens in an inclined state, thereby guiding the compressed oil residue to enter the specified container.

[0058] The compression plate 201a will then continue to rise, at which time the compression block 203a will separate from the dial plate 202j, and then the locking block 202e can be returned to its original position through the force of the second torsion spring 202g rotating. When the compression plate 201a continues to rise, it will drive the second moving rod 203d to move, and the second moving rod 203d will drive the driving plate 203c to move. The movement of the driving plate 203c can squeeze the closed door 202a, thereby closing the closed door 202a, and then the closed door 202a will drive the locking rod 202d to engage with the locking rod 202d. At this time, the closed door 202a can be limited. A first door body is provided on one side of the oil-water separator 101. By opening the first door body, a container for collecting oil residue can be placed under the filter frame 102 to collect the compressed oil residue. A second door body is also provided at one end of the oil-water separator 101. By opening the second door body, the filter frame 102 can be disassembled, which is convenient for replacing or maintaining the filter frame 102.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
