Description

Technical Field

[0001] This utility model relates to an oil-water separator, and more particularly to a filter basket mounting structure for an oil-water separator. Background Technology

[0002] In food waste treatment, oil-water separators are common devices for separating oil and water. Existing technologies, such as patent application number "201821752557.0" entitled "An Under-Sink Oil-Water Separator," use solid-liquid separation before oil-water separation, filtering the solids in the oil and water through a filter frame. However, this structure has the following shortcomings:

[0003] 1. The filter frame has a side pull-out structure. With this structure, a sealing ring needs to be installed on the side to prevent water leakage. However, after a period of use, the sealing ring is easily damaged due to the long-term exposure to oil and water, which can lead to water leakage.

[0004] 2. With pull-out filter frames, oil and water inside can easily leak out from the side during the removal process, requiring subsequent cleaning, which is also very inconvenient. Summary of the Invention

[0005] The purpose of this utility model is to provide a filter basket installation structure for an oil-water separator. By using this structure, the ease of placing and removing the filter basket can be ensured, while also preventing water leakage.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a filter basket installation structure for an oil-water separator, comprising a filter basket installed inside the oil-water separation chamber of the oil-water separator. The oil-water separator includes a housing, and an inlet communicating with the oil-water separation chamber is provided on the right side wall of the housing. The filter basket is located beside the inlet.

[0007] Two support plates are spaced apart on the right side of the oil-water separation chamber, and the top plane of the support plates is located below the bottom plane of the liquid inlet.

[0008] The filter basket has outwardly extending extension plates on both sides of its top. The filter basket is placed between two support plates, and each extension plate abuts against the top surface of one of the support plates.

[0009] The oil-water separation chamber is also provided with a liquid inlet bend. The right end of the liquid inlet bend is detachably inserted into the liquid inlet. The liquid inlet bend is rotatably connected to the liquid inlet. The left end of the liquid inlet bend is inserted into the filter basket, and the left end of the liquid inlet bend is located close to the left inner wall of the filter basket.

[0010] In the above technical solution, an annular protrusion is provided on the outer surface of the right end of the liquid inlet bend, and the right side of the annular protrusion abuts against the right inner wall of the oil-water separation chamber.

[0011] In the above technical solution, the liquid inlet bend on the right side of the annular protrusion is inserted into the liquid inlet. An elastic sealing layer is provided on the outer surface of the liquid inlet bend on the right side of the annular protrusion. The outer surface of the elastic sealing layer abuts against the inner wall of the liquid inlet. The elastic sealing layer seals the connection between the liquid inlet and the liquid inlet bend.

[0012] In the above technical solution, the distance between the left end of the inlet bend and the inner wall of the left side of the filter basket is less than the length of the inlet bend on the right side of the annular protrusion.

[0013] In the above technical solution, the outlet at the left end of the inlet bend is positioned downwards.

[0014] In the above technical solution, a handle is provided on the front side and the rear side of the top of the filter basket.

[0015] In the above technical solution, each of the support plates has a support slot at its top, and each of the extension plates is placed in the support slot. The length of the support slot is greater than or equal to the length of the extension plate.

[0016] In the above technical solution, the top of the box is provided with a through groove that communicates with the oil-water separation chamber, and the through groove is positioned directly opposite the filter basket.

[0017] In the above technical solution, a cover plate that opens and closes the through slot is movably installed on the top of the box.

[0018] In the above technical solution, a slide rail is provided on the top of the box on the front and rear sides of the through groove, the left end of the slide rail is located on the left side of the through groove, and the bottom of the cover plate is slidably mounted on the slide rail;

[0019] When the cover plate slides to the rightmost end of the slide rail, the cover plate closes the through slot; when the cover plate slides to the leftmost end of the slide rail, the through slot is opened.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] 1. In this utility model, the filter basket adopts a hollow structure with an open top. The filter basket is placed directly on the support plate and supported by the support plate. A rotatable inlet bend is inserted into the liquid inlet, so that the oil-water mixture entering the liquid inlet passes through the inlet bend and directly enters the filter basket for solid-liquid separation. When the filter basket is removed, it is only necessary to rotate the inlet bend and remove it to quickly remove the filter basket. This not only prevents water leakage but also does not affect the convenience of removing and placing the filter basket.

[0022] 2. The filter basket in this utility model adopts a lift-type pick-and-place method to prevent water leakage during the pick-and-place process. It is also convenient to pick up and place, and it is easy to quickly clean the solid matter in the filter basket. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: See Figure 1-5 As shown, a filter basket mounting structure for an oil-water separator includes a filter basket 1, which is installed inside the oil-water separation chamber 2 of the oil-water separator. The oil-water separator includes a housing 3, and a liquid inlet 4 communicating with the oil-water separation chamber 2 is provided on the right side wall of the housing 3. The filter basket 1 is located beside the liquid inlet 4.

[0031] Two support plates 5 are provided on the right side of the oil-water separation chamber 2 at intervals, and the top plane of the support plate 5 is located below the bottom plane of the liquid inlet 4.

[0032] The filter basket 1 has outwardly extending extension plates 6 on both sides of its top. The filter basket 1 is placed between two support plates 5, and each extension plate 6 abuts against the top surface of one of the support plates 5.

[0033] The oil-water separation chamber 2 is also provided with an inlet bend 7. The right end of the inlet bend 7 is detachably inserted into the inlet port 4. The inlet bend 7 is rotatably connected to the inlet port 4. The left end of the inlet bend 7 is inserted into the filter basket 1, and the left end of the inlet bend 7 is located close to the left inner wall of the filter basket 1.

[0034] In this embodiment, the oil-water separation chamber is used for oil-water separation. The side wall of the chamber is also equipped with a water outlet 8 and an oil outlet 9. The water outlet discharges the water after oil-water separation, and the oil outlet discharges the grease after oil-water separation. When the oil-water mixture (liquid) is fed into the oil-water separation chamber, it enters through the inlet, passes through the inlet bend, and exits through the outlet at the left end of the inlet bend. The outlet at the left end of the inlet bend faces downwards, so the liquid flows directly downwards into the filter basket. The filter basket has a perforated structure with an open top, which filters the solids in the liquid, achieving solid-liquid separation. The liquid enters the oil-water separation chamber for oil-water separation, while the solids remain in the filter basket. When the solids in the filter basket reach a certain level and need to be cleaned, the operator lifts the filter basket away from the support plate and detaches it from the chamber for quick cleaning of the solids. It is then reinserted into the oil-water separation chamber, supported by the support plate on the extension plate. In this embodiment, to facilitate the easy placement and removal of the filter basket without obstruction by the inlet bend, the right end of the inlet bend is detachably inserted into the inlet and rotatably connected to it. The left end of the inlet bend is inserted into the filter basket and positioned close to the left inner wall of the filter basket. In this way, during normal use, the liquid fed into the inlet will smoothly enter the filter basket through the inlet bend for solid-liquid separation. Furthermore, if the inlet bend moves to the left to disengage from the inlet, it will be limited by the filter basket, thus ensuring normal liquid intake through the inlet bend. When the filter basket needs to be removed, the operator grasps the inlet bend and rotates it so that the left end of the inlet bend faces upwards. At this point, the left end of the inlet bend will rotate to the top of the filter basket, and the filter basket will no longer restrict the leftward movement of the inlet bend. The operator then moves the inlet bend to the left and pulls it out of the inlet port, thus disassembling the inlet bend and the inlet port. Now that the filter basket is no longer restricted by the inlet bend, it can be directly removed and disassembled from above. After cleaning the debris from inside the filter basket, place it directly between the two support plates, with the extension plate resting against the corresponding support plate, thus providing support and restraint for the filter basket. Next, insert the right end of the inlet bend into the inlet, with the left end of the inlet bend facing upwards. After inserting the right end of the inlet bend into the inlet, rotate the inlet bend so that the left end faces downwards and is inserted into the filter basket. This uses the filter basket to restrict the inlet bend from moving to the left and disengaging from the inlet. In this invention, the filter basket is placed vertically to prevent leakage and facilitates easy placement and removal.

[0035] See Figure 3-5 As shown, an annular protrusion 10 is provided on the outer surface of the right end of the liquid inlet bend 7, and the right side of the annular protrusion 10 abuts against the right inner wall of the oil-water separation chamber 2.

[0036] The liquid inlet bend 7 on the right side of the annular protrusion 10 is inserted into the liquid inlet 4. An elastic sealing layer 11 is provided on the outer surface of the liquid inlet bend 7 on the right side of the annular protrusion 10. The outer surface of the elastic sealing layer 11 abuts against the inner wall of the liquid inlet 4. The elastic sealing layer 11 seals the connection between the liquid inlet 4 and the liquid inlet bend 7.

[0037] The distance between the left end of the liquid inlet bend 7 and the inner wall of the left side of the filter basket 1 is a, and the length of the liquid inlet bend 7 on the right side of the annular protrusion 10 is b, where a is less than b.

[0038] The annular protrusion limits the insertion length of the right end of the inlet bend into the inlet. Simultaneously, the length of the right end of the inlet bend and the distance between its left end and the filter basket ensure that when the inlet bend moves to the left, its right end remains within the inlet when its left end rests against the filter basket. This guarantees the normal flow guidance function of the inlet bend, ensuring that all liquid entering the filter basket after passing through it undergoes solid-liquid separation. The elastic sealing layer increases the friction between the inlet bend and the inlet, preventing rotation or movement of the inlet relative to it under less than a certain external force. It also provides a seal, ensuring that liquid can only enter the filter basket through the inlet bend for solid-liquid separation.

[0039] In this embodiment, the inlet bend 7 includes a straight section 12, a curved section 13, and an outlet section 14. The axis of the straight section is parallel to the axis of the inlet. The right end of the curved section is connected to the left end of the straight section, and the top of the outlet section is connected to the left end of the curved section. An annular protrusion is provided at the connection between the curved section and the straight section, or the annular protrusion is provided on the straight section. The right end of the straight section is inserted into the inlet. An elastic sealing layer is covered on the outer surface of the straight section. Preferably, the elastic sealing layer is made of rubber or silicone. The outlet section can be inclined or perpendicular to the straight section. During normal use, the outlet section is inserted into the filter basket and is positioned close to the left inner wall of the filter basket. When the filter basket needs to be disassembled, the inlet bend is rotated so that the outlet section rotates upward and disengages from the filter basket, placing it above the filter basket. Then, the inlet bend is pulled to the left to disengage the straight section from the inlet, thus achieving disassembly of the inlet bend.

[0040] See Figure 5 As shown, a handle 15 is provided on the front side and the rear end of the top of the filter basket 1. The handles facilitate the operator to remove the filter basket from the oil-water separation chamber and make it easy to put the filter basket in and out.

[0041] See Figure 5As shown, each of the support plates 5 has a support slot 16 at its top, and each of the extension plates 6 is placed in the support slot 16. The length of the support slot 16 is greater than or equal to the length of the extension plate 6.

[0042] The two support plates not only support the filter basket but also restrict its movement to prevent it from moving left or right. In order to restrict the forward and backward movement of the filter basket, a support slot is also provided to limit its forward and backward movement.

[0043] See Figure 1 , 2 As shown, the top of the housing 3 has a through groove 17 that communicates with the oil-water separation chamber 2, and the through groove 17 is positioned directly opposite the filter basket 1. The through groove facilitates the placement and removal of the filter basket.

[0044] See Figure 1 , 2 As shown, a cover plate 18 is movably installed on the top of the housing 3 to open and close the through channel 17. The cover plate, during normal oil-water separation, closes the through channel, making it more aesthetically pleasing, environmentally friendly, and safer.

[0045] See Figure 1 , 2 As shown, a slide rail 19 is provided on the top of the box on the front and rear sides of the through groove 17, the left end of the slide rail 19 is located on the left side of the through groove 17, and the bottom of the cover plate 18 is slidably mounted on the slide rail 19.

[0046] When the cover plate 18 slides to the rightmost end of the slide rail 19, the cover plate 18 closes the through groove 17; when the cover plate 18 slides to the leftmost end of the slide rail 19, the through groove 17 is opened.

[0047] The sliding rails limit the movement of the cover plate, making it a translational rather than a rotating structure, thus reducing space occupation and preventing the cover plate from being lost.
