Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, and particularly relates to an oil-water separation device. Background Art

[0002] With the booming development of the catering industry, the generation amount of oily wastewater in the kitchen has increased significantly. In addition to the oil substances existing in the forms of floating oil, emulsified oil and dissolved oil, a large amount of suspended substances enter the drainage pipeline. After bonding with the oil, it is easy to block the drainage pipe network and subsequent equipment and produce malodors, affecting the environment. At the same time, after such wastewater is discharged into the water body, the oil substances float on the water surface, affecting the reoxygenation of the water body and its natural purification process, endangering the water body ecosystem and seriously polluting the surrounding environment.

[0003] At present, the catering industry generally uses a simple oil interceptor to separate oil and water from oily sewage. Because the oil interceptor has a low cost and a simple process, it has been widely used in the catering industry. However, the oil interceptor only separates the oil from the oil-water mixture by using the different specific gravities of oil and water. This method can only do simple oil-water collection, and its treatment effect is poor. And after simple treatment, the wastewater is directly discharged into the sewer, which will cause problems such as oil accumulation, caking and deterioration, difficult to clean out, and pipeline blockage.

An oil and grease separation device provided by an embodiment of the present utility model is mainly applied to the treatment of waste oil and grease and residues generated in kitchens such as canteens, and after residue, oil and water separation, it is discharged into the municipal pipe network to avoid environmental pollution.

[0045] As Figures 1 to 5 shown, the oil and water separation device includes: a slag storage chamber 1, a first oil and water separation chamber 2, a water storage chamber 3, a cleaning chamber 4, and an oil storage chamber 5; the slag storage chamber 1 is provided with a water inlet 1a and a water outlet 1b, and a slag retaining plate 11 is arranged therein near the water outlet 1b; the first oil and water separation chamber 2 is formed by enclosing a side plate 23, a bottom plate 21, a first oil retaining plate 22, and the side wall of the slag storage chamber 1; the side plate 23 is fixedly connected to the side wall of the slag storage chamber 1; one side edge of the bottom plate 21 abuts against the side wall of the slag storage chamber 1, and the other side edge of the bottom plate 21 away from the side wall of the slag storage chamber 1 is connected to the first oil retaining plate 22 through a horizontal rotating shaft 24, and the bottom plate 21 and the first oil retaining plate 22 can rotate around the axis along with the horizontal rotating shaft 24; the horizontal rotating shaft 24 is fixed on the side plate 23; the bottom plate 21 is provided with a first filtering hole 211; the water outlet 1b of the slag storage chamber is communicated with the first oil and water separation chamber 2; the water storage chamber 3 is arranged at the bottom of the bottom plate 21, and its top is provided with a top plate 31, and the top plate 31 is provided with a second filtering hole 311, and the first filtering hole 211 is communicated with the water storage chamber 3 through the second filtering hole 311; the cleaning chamber 4 is arranged on one side of the first oil and water separation chamber 2, and the first oil retaining plate 22 and the bottom plate 21 can respectively rotate into the cleaning chamber 4; a water spraying device 41 containing an oil remover is arranged in the cleaning chamber 4 for flushing the bottom plate 21 and the first oil retaining plate 22; the oil storage chamber 5 is arranged on one side of the first oil and water separation chamber 2; an opening 22a is arranged at the top of the first oil retaining plate 22, and the opening 22a is communicated with the oil inlet 5a of the oil storage chamber.

[0046] Among them, the main purpose of the slag storage chamber 1 is to remove the residues in the kitchen waste. It is usually arranged under the kitchen sewage drain, formed by digging earthwork, and its top is an open end. The waste oil and grease and residues generated in the kitchen are discharged into the slag storage chamber 1 through the sewer.

[0047] On one side of the slag storage chamber 1, a water outlet 1b is provided. A slag baffle 11 is vertically placed in front of the water outlet 1b of the slag storage chamber, facilitating the interception of residues within the slag storage chamber 1. The slag baffle 11 can be designed as a perforated plate or a filter screen. The residues are intercepted within the slag storage chamber 1, and the oil-water mixture passes through the slag baffle 11 and is discharged from the water outlet 1b of the slag storage chamber. The slag baffle 11 can also be a side wall of the slag storage chamber 1, and the perforations or filter holes are the water outlet 1b of the slag storage chamber.

[0048] The residues stored in the slag storage chamber 1 can be manually removed regularly, or a perforated container 12 separated from the slag storage chamber 1 can be provided within the slag storage chamber 1. The perforated container 12 is provided with a handle 121. The residues are intercepted in the perforated container 12. When it reaches a certain capacity, by lifting the handle 121, the perforated container 12 is taken out of the slag storage chamber 1. After residue recovery and cleaning, it is put back into the slag storage chamber 1 again. By repeatedly extracting and putting back the perforated container 12 like this, a large amount of residues discharged from the sewer can be recovered. The perforated container 12 saves time and effort compared to manual removal and is convenient to operate. The perforated container 12 can usually be a perforated bamboo basket, a perforated iron bucket made of stainless steel, etc.

[0049] The top of the slag storage chamber 1 can be designed as an open end, and its top is sealed by a cover plate 13.

[0050] A waterproof layer can be provided on the inner side wall of the slag storage chamber 1 to waterproof the slag storage chamber 1, preventing the waste oil and residues generated from the kitchen from seeping into the underground soil or overflowing onto the ground, causing environmental pollution.

[0051] The first oil-water separation chamber 2 is arranged on the side of the slag storage chamber 1 and is surrounded by a side plate 23, a bottom plate 21, a first oil baffle 22, and the side wall of the slag storage chamber 1.

[0052] There are usually two side plates 23, which are relatively fixedly arranged on the outer side wall of the slag storage chamber 1. The bottom plate 21 and the first oil baffle 22 are connected by a horizontal rotating shaft 24 and can rotate around the horizontal rotating shaft 24, where the horizontal rotating shaft 24 is fixed between the two side plates 23.

[0053] Specifically, movable holes are respectively provided at the bottom of one side of the two side plates 23 away from the side wall of the slag storage chamber 1, and both ends of the horizontal rotating shaft 24 are respectively inserted into the two movable holes to achieve the fixation and axial rotation of the horizontal rotating shaft 24.

[0054] The oil-water mixture discharged from the water outlet 1b of the slag storage chamber enters the first oil-water separation chamber 2. Since the density of oil substances is less than that of water, under the action of gravity, the oil substances float above the water surface, realizing automatic oil-water stratification.

[0055] A water storage chamber 3 is provided at the bottom of the first oil-water separation chamber 2. The water phase is discharged into the lower water storage chamber 3 through the first filter holes 211 at the bottom of the bottom plate 21, and the oil phase remains in the first oil-water separation chamber 2.

[0056] A storage oil chamber 5 is arranged on the side of the first oil-water separation chamber 2. When the oil level is close to the opening 22a of the first baffle 22 or when there is less water phase remaining in the first oil-water separation chamber 2, the bottom plate 21 and the first baffle 22 are rotated by rotating the horizontal rotating shaft 24 to tilt towards the side where the storage oil chamber 5 is located, and the oil phase flows out obliquely from the opening 22a into the storage oil chamber 5.

[0057] The opening 22a can be communicated with the storage oil chamber 5 through an oil pipe, and the oil phase flows into the storage oil chamber 5 through the oil pipe, or the top of the storage oil chamber 5 is designed to be open, and the oil phase flows out from the opening 22a of the first baffle 22 and is poured into the storage oil chamber 5 from the open top.

[0058] After the pouring is completed, the bottom plate 21 and the first baffle 22 are rotated back to their original positions again to receive the oil and water flowing out from the slag storage chamber 1. Repeating the above back-and-forth pouring multiple times can ensure the continuous separation process of the oil and water.

[0059] When the bottom plate 21 rotates upward along with the horizontal rotating shaft 24, a separation occurs between the bottom plate 21 and the slag storage chamber 1. In order to prevent a large amount of oil and water discharged from the slag storage chamber 1 from being injected into the water storage chamber 3, a top plate 31 is arranged at the top of the water storage chamber 3. After the bottom plate 21 deviates, the top plate 31 receives the discharged oil and water. At this time, the top plate 31, the bottom plate 21, the side plate 23, and the outer side wall of the slag storage chamber 1 form a second oil-water separation chamber. The top plate 31 is provided with a second filter hole 311, and the water phase continues to flow into the water storage chamber 3 through the second filter hole 311.

[0060] Furthermore, an aeration device 26 that can supply oxygen to the oil and water can be arranged in the first oil-water separation chamber 2 to reduce the foul smell generated after the oil-containing sewage ferments and deteriorates.

[0061] A cleaning chamber 4 is arranged in the first oil-water separation chamber 2. A water spraying device 41 is installed in the cleaning chamber 4, and an oil remover is filled in the water spraying device 41. The purpose is to immediately clean the top plate 31, the bottom plate 21, and the first oil baffle 22 to prevent the filter holes from being blocked by oil stains.

[0062] Among them, the bottom plate 21 and the first oil baffle 22 can be rotated into the cleaning chamber 4 along with the rotation of the horizontal rotating shaft 24 and are rinsed by the water spraying device 41 in the cleaning chamber 4.

[0063] The top plate 31 can rotate around one of its sides and can be rotated into the cleaning chamber 4 to be rinsed by the water spraying device 41. Specifically, a vertical shaft 33 can be arranged at the top of the water storage chamber 3 close to the cleaning chamber 4. A shaft sleeve 32 is arranged in the middle of one side of the top plate 31, and the shaft sleeve 32 is sleeved on the vertical shaft 33 to realize the horizontal rotation of the top plate 31, and the top plate 31 can be integrally rotated into the cleaning chamber 4.

[0064] After the flushing is completed, the top plate 31, the bottom plate 21, and the first oil baffle 22 return to their original positions to continue receiving oil and water. By cycling in this way, oil-water separation in kitchen waste oil and grease can be achieved.

[0065] It should be noted that the water spraying device 41 can be installed on the top of the cleaning chamber 4 or on the inner wall of the cleaning chamber 4 on the side opposite to the first oil baffle 22, and is preferably set on the top of the inner wall. Multiple water spraying devices 41 can also be provided to perform all-round flushing on the bottom plate 21, the first oil baffle 22, and the top plate 31.

[0066] In the embodiment of the present utility model, by providing a rotatable first oil-water separation chamber 2 and filtering holes at the bottom, immediate recovery of the oil phase and the water phase can be achieved, avoiding the accumulation, caking, and deterioration of grease. At the same time, the bottom plate 21 and the top plate 31 for receiving oil and water can both be rotated into the cleaning chamber 4 for immediate oil removal and cleaning, avoiding blockage of the filtering holes, ensuring the continuous progress of the oil-water separation process, and having a good oil-water separation effect.

[0067] Embodiment 2:

[0068] Based on the same inventive concept, an oil and grease separation device provided in this embodiment is basically the same as that in Embodiment 1. For the sake of brevity in description, during the description of this embodiment, the same technical features as those in Embodiment 1 will not be described again, and only the differences between this embodiment and Embodiment 1 will be described:

[0069] A second oil baffle 25 is hinged to the bottom of the bottom plate 21. The second oil baffle 25 can block the first filtering hole 211 as the bottom plate 21 rotates upward. When the bottom plate 21 rotates into the cleaning chamber 4, the second oil baffle 25 and the top plate 31, the side plate 23, and the side wall of the slag storage chamber 1 form a second oil-water separation chamber.

[0070] The second oil baffle 25 is hinged to the bottom of the bottom plate 21. When the bottom plate 21 rotates upward, due to the action of gravity, the second oil baffle 25 can gradually fit the bottom plate 21 and cover one side surface of the bottom plate 21, that is, the second oil baffle 25 blocks the first filtering hole 211 of the bottom plate 21, which can prevent the oil phase in the second oil-water separation chamber from flowing into the space formed by the bottom plate 21 and the first oil baffle 22 through the first filtering hole 211 of the bottom plate 21. That is, when the bottom plate 21 and the first oil baffle 22 rotate into the cleaning chamber 4 for cleaning, the second oil baffle 25 plays a role in blocking oil for the first filtering hole 211, and the water spraying device 41 can continuously perform oil removal and flushing on the bottom plate 21, making the cleaning more thorough.

[0071] Further, in order to achieve overall coverage of the side surface of the bottom plate 21, the second oil baffle 25 can be designed as a foldable baffle. The length and width after its expansion are both greater than or equal to the length and width of the bottom plate 21. The hinged end of the second oil baffle 25 is hinged to the bottom edge of the rotating end of the bottom plate 21. As it rotates upward, the second oil baffle 25 unfolds, and its non-hinged end always remains in contact with the top plate 31, so that the side surface of the bottom plate 21 can be fully covered.

[0074] A through port 4a communicating with the oil inlet 5a of the oil storage chamber is provided on the side wall of the cleaning chamber 4; a rotatable oil guiding plate 42 is provided at the through port 4a in the cleaning chamber 4; when the first oil baffle 22 rotates into the cleaning chamber 4 and inclines downward to the through port 4a, the opening 22a of the first oil baffle 22 is connected to the through port 4a through the oil guiding plate 42.

[0075] The through port 4a and the oil inlet 5a of the oil storage chamber can be connected through an oil pipe.

[0076] When the first oil baffle 22 rotates into the cleaning chamber 4 and inclines downward to the through port 4a, adjust the rotation angle of the rotatable oil guiding plate 42 so that the first oil baffle 22 is connected to the through port 4a through the oil guiding plate 42. The oil phase tilts out from the opening 22a of the first oil baffle 22, flows into the through port 4a through the oil guiding plate 42, and then flows into the oil storage chamber 5 through the oil pipe.

[0077] After all the oil phase flows into the oil storage chamber 5, adjust the rotation angle of the oil guiding plate 42 to separate the first oil baffle 22 from the oil guiding plate 42, and it can continue to incline downward so that the bottom plate 21 and the first oil baffle 22 all rotate into the cleaning chamber 4.

[0078] Embodiment 4:

[0079] Based on the same inventive concept, an oil and water separation device provided in this embodiment is basically the same as that in Embodiment 3. For the sake of brevity in description, during the description of this embodiment, the same technical features as those in Embodiment 3 will not be described again, and only the differences between this embodiment and Embodiment 3 will be described:

[0080] The oil and water separation device further includes:

[0081] The first driving mechanism 6, whose rotating shaft is connected to the horizontal rotating shaft 24 to drive the horizontal rotating shaft 24 to rotate; the second driving mechanism 7, whose rotating shaft is connected to one side of the top plate 31 to drive the top plate 31 to rotate; and the third driving mechanism 8, whose rotating shaft extends into the cleaning chamber 4 and is connected to the oil guiding plate 42 to drive the oil guiding plate 42 to rotate.

[0082] Further, an oil level sensor 221 is provided at the opening 22a of the first oil baffle 22 for real-time detection of the oil level height in the first oil-water separation chamber 2.

[0083] The oil-water separation device further includes:

[0084] The control device 10 is electrically connected to the first driving mechanism 6, the second driving mechanism 7, the third driving mechanism 8, the water spraying device 41 and the oil level sensor 221, and is used for receiving the oil level height data detected in real time by the oil level sensor 221 and controlling the start of the first driving mechanism 6, the second driving mechanism 7, the third driving mechanism 8 and the water spraying device 41 according to the data.

[0085] Embodiment 5:

[0086] Based on the same inventive concept, an oil stain separation device provided in this embodiment is basically the same as that in Embodiment 1. For the sake of brief description, during the description of this embodiment, the same technical features as those in Embodiment 1 will not be described again, and only the differences between this embodiment and Embodiment 1 will be described:

[0087] The oil-water separation device further includes:

[0088] The purification device 9 includes an oil removal pipeline 91, a water outlet pipeline 92 and a water pump 93. The oil removal pipeline 91 is communicated with the outlet of the water storage chamber 3 through the water outlet pipeline 92; an oil-absorbing material is laminated inside the oil removal pipeline 91; the water pump 93 is arranged on the water outlet pipeline 92.

[0089] The water phase collected by the water storage chamber 3 flows into the oil removal pipeline 91 through the water pump 93, and the oil-absorbing material absorbs and removes the residual grease in the water phase, so that the finally discharged water phase contains very little grease and residue, meeting the requirements of urban sewage discharge.

[0090] The water pump 93 makes the flowing water have a large impact pressure, which can make the grease be fully absorbed by the oil-absorbing material, greatly reducing the grease content of the discharged sewage. The oil-absorbing material can be oil-absorbing cotton or oil-absorbing paper, and the oil removal pipeline 91 can be designed as a U-shaped, W-wave-shaped or spiral-shaped pipeline to increase the sewage flow path and improve the oil removal rate, but the oil-absorbing material and the oil removal pipeline 91 are not specifically limited in the embodiments of the present invention.

[0093] Refer to Figure 6 As shown, the water storage chamber 3 further includes a sealing plate 34 disposed between the bottom plate 21 and the top plate 31 and enclosing the gap therebetween to form a sealed space.

[0094] The sealing plate 34 functions to block, preventing the oil stain in the first oil-water separation chamber 2 from flowing out through the gap between the bottom plate 21 and the top plate 31 when the bottom plate 21 rotates upward.
