Abstract
Description
Technical Field
[0001] The utility model discloses a kitchen waste oil-water separation device, belonging to the technical field of waste treatment equipment. Background Art
[0002] Large amounts of food waste are generated in kitchens in homes, restaurants, and hotels. This waste primarily consists of solid waste, water, and grease. Currently, the conventional treatment method involves filtering the waste, leaving behind a mixture of oil and water that is then discharged into the city's pipe network and subsequently transported to a sewage treatment plant for treatment.
[0003] At present, due to the presence of oil in the oil-water mixture, when the oil-water mixture is discharged into the urban pipeline network, the oil will accelerate the aging of the urban pipeline network, and a small amount of tiny solids in the oil-water mixture will be deposited in the urban pipeline network, which will cause the urban pipeline network to be blocked over time. Therefore, it is necessary to separate the oil and water from the oil-water mixture generated by food waste.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0005] The purpose of the present invention is to solve the above-mentioned problem and to provide a kitchen waste oil-water separation device, which has the effect of separating oil and liquid in kitchen waste.
[0006] The utility model achieves the above-mentioned purpose through the following technical scheme, including a separation box, a separation chamber is provided in the separation box, a feed port connected to the separation chamber is provided at the upper left end of the separation box, an inclined separation plate is provided in the separation chamber, the left end of the separation plate is connected to the side wall of the separation box, and the right end of the separation plate extends obliquely downward to the right, a groove is provided in the middle of the separation plate, a plurality of through holes are provided at the bottom of the groove, an oil-absorbing and hydrophobic sponge is provided at the groove of the separation plate, an oil collecting barrel is provided at the corresponding groove on the lower side of the separation plate in the separation chamber, a water collecting barrel is provided on the right side of the separation chamber, and the right end of the separation plate extends to the upper side of the water collecting barrel.
[0007] By adopting the above technical solution, after the oil-water mixture is poured into the separation chamber in the separation box from the feed port, the oil-water mixture falls on the left end of the separation plate, and flows to the right under the action of the inclined state of the separation plate. When the oil-water mixture flows through the oil-absorbing and hydrophobic sponge on the groove, the oil in the oil-water mixture is absorbed by the oil-absorbing and hydrophobic sponge. When a lot of oil is absorbed, the oil flows downward through the through hole under the action of gravity and falls into the oil collecting barrel, while the water in the oil-water mixture continues to flow to the right through the oil-absorbing and hydrophobic sponge and flows into the water collecting barrel, thereby completing the oil-water separation of the oil-water mixture. At the same time, the design of extending the right end of the separation plate to the upper side of the water collecting barrel can effectively ensure that the water separated from the oil-water mixture flows stably into the water collecting barrel.
[0008] Preferably, an extrusion device is provided at the position of the groove corresponding to the upper end of the separation box, and the extrusion device includes a cylinder, an extrusion plate and a piston rod arranged in the cylinder. The cylinder is arranged at the upper end of the separation box and the piston rod extends into the separation chamber. The extrusion plate is arranged in the separation chamber and is located on the upper side of the groove. The extrusion plate is arranged at an angle and the inclination angle is the same as the inclination angle of the separation plate. The upper end of the extrusion plate is connected to the piston rod.
[0009] By adopting the above technical solution, the cylinder can drive the piston rod to move downward, driving the extrusion plate connected to the piston rod to move downward, and the extrusion plate is tilted and the inclination angle is the same as the inclination angle of the separation plate. The extrusion plate arranged on the upper side of the groove can squeeze the oil-absorbing and hydrophobic sponge after moving downward, thereby squeezing out the grease in the oil-absorbing and hydrophobic sponge and causing it to pass downward through the through hole and fall into the oil collecting barrel, effectively improving the efficiency of the device in collecting oil.
[0010] Preferably, the separation box is provided with a filter sleeve at the feed inlet, the filter sleeve is detachably sleeved on the inner side of the feed inlet, and a filter screen is provided inside the filter sleeve.
[0011] By adopting the above technical solution, the tiny solids in the oil-water mixture can be filtered through the filter mesh in the filter sleeve to complete solid-liquid separation, thereby preventing the tiny solids from clogging the device and affecting the oil-water separation effect of the device. The design of the filter sleeve being detachably mounted on the feed inlet allows the filter sleeve to be easily disassembled for cleaning and replacement, making the device easier to clean and maintain.
[0012] Preferably, an oil baffle is provided at the rightmost end of the groove corresponding to the lower side of the separation plate.
[0013] By adopting the above technical solution, an oil baffle can be set to block the grease and guide the grease to flow downward into the oil collecting barrel, preventing the grease from flowing along the lower side of the separation plate to the right end of the separation plate after passing through the through hole, resulting in the grease not flowing into the oil collecting barrel.
[0014] Preferably, the front side of the separation box is provided with an openable and closable box door.
[0015] By adopting the above technical solution and providing an openable and closable box door, the device can be easily cleaned and maintained regularly, thereby improving the maintainability and operating convenience of the device.
[0016] Preferably, the oil-absorbing and hydrophobic sponge is made of graphene material.
[0017] By adopting the above technical solutions, graphene materials, with their excellent oil absorption and hydrophobicity, provide a more efficient and environmentally friendly solution for oil-water separation.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] Firstly, the device effectively separates oil and water from kitchen waste by using an inclined separation plate with grooves and an oil-absorbing and hydrophobic sponge. The special material of the oil-absorbing and hydrophobic sponge selectively absorbs oil and repels water, thereby improving the efficiency and accuracy of oil-water separation. In addition, the through-holes at the bottom of the groove and the oil collection bucket allow the separated oil to be collected smoothly, avoiding secondary contamination.
[0020] Secondly, the squeezing device is designed to automatically squeeze the oil-absorbing and hydrophobic sponge, which helps to discharge the absorbed grease more thoroughly into the oil collection barrel, improves the grease recovery efficiency and the reuse rate of the sponge, and reduces the trouble and cost of manual operation;
[0021] Thirdly, the design of the filter sleeve and filter screen provides a preliminary filtration function for the kitchen waste before it enters the separation chamber, which can effectively remove tiny solids and protect the separation plate and oil-absorbing hydrophobic sponge from being blocked, thus extending the service life of the entire device and improving the separation effect;
[0022] Fourthly, the oil baffle design further prevents the overflow and outflow of grease during the separation process, ensuring that the grease can accurately flow into the oil collection barrel, thereby improving the accuracy of oil-water separation and the cleanliness of the device.

Under the action of the inclined state of the separation plate 4, the oil-water mixture flows to the right. When the oil-water mixture flows through the oil-absorbing and hydrophobic sponge 6 on the groove, the grease in the oil-water mixture is absorbed by the oil-absorbing and hydrophobic sponge 6. When a lot of grease is absorbed, the grease flows downward through the through hole 5 under the action of gravity and falls into the oil collecting barrel 7, while the water in the oil-water mixture continues to flow to the right through the oil-absorbing and hydrophobic sponge 6 and flows into the water collecting barrel 8, thereby completing the oil-water separation of the oil-water mixture. At the same time, the design of the right end of the separation plate 4 extending to the upper side of the water collecting barrel 8 can effectively ensure that the water separated from the oil-water mixture flows stably into the water collecting barrel 8.
[0028] The upper end of the separation box 1 is provided with an extrusion device at the position corresponding to the groove, and the extrusion device includes a cylinder 9, an extrusion plate 10 and a piston rod 11 arranged in the cylinder 9. The cylinder 9 is arranged at the upper end of the separation box 1 and the piston rod 11 extends into the separation chamber 2. The extrusion plate 10 is arranged in the separation chamber 2 and is located on the upper side of the groove. The extrusion plate 10 is tilted and the inclination angle is the same as the inclination angle of the separation plate 4. The upper end of the extrusion plate 10 is connected to the piston rod 11. The cylinder 9 can drive the piston rod 11 to move downward, driving the extrusion plate 10 connected to the piston rod 11 to move downward. The extrusion plate 10 is tilted and the inclination angle is the same as the inclination angle of the separation plate 4.

A filter screen 13 is provided in the filter sleeve 12. The filter screen 13 in the filter sleeve 12 can filter the tiny solids in the oil-water mixture to complete the solid-liquid separation, thereby preventing the tiny solids from clogging the device and affecting the oil-water separation effect of the device. The design of the filter sleeve 12 being detachably mounted on the feed port 3 allows the filter sleeve 12 to be easily disassembled for cleaning and replacement, making the device easier to clean and maintain. An oil retaining wall is provided at the rightmost end of the corresponding groove on the lower side of the separation plate 4. Plate 14, by setting the oil baffle plate 14, the grease can be blocked and guided to flow downward into the oil collecting barrel 7, to prevent the grease from flowing along the lower side of the separation plate 4 to the right end of the separation plate 4 after passing through the through hole 5, resulting in the grease not flowing into the oil collecting barrel 7.

[0030] When the oil-water mixture of the kitchen waste needs to be separated, the oil-water mixture is poured into the separation chamber 2 from the filter sleeve 12 at the feed port 3. The oil-water mixture is filtered through the filter screen 13 in the filter sleeve 12 to separate the tiny solids, so that only the liquid oil-water mixture falls onto the separation plate 4 in the separation chamber 2. After the oil-water mixture falls onto the separation plate 4, due to the tilt of the separation plate 4, the oil-water mixture moves from the left end to the right end of the separation plate 4. When the oil-water mixture passes through the oil-absorbing and hydrophobic sponge 6 provided in the groove in the middle of the separation plate 4, the oil The oil in the water mixture is absorbed by the oil-absorbing and hydrophobic sponge 6, while the water still moves to the right end along the separation plate 4 and flows into the water collecting bucket 8. The oil absorbed by the oil-absorbing and hydrophobic sponge 6 passes downward through the through hole 5 under the action of gravity and flows into the water collecting bucket 8. When the oil-absorbing and hydrophobic sponge 6 absorbs more oil, the cylinder 9 starts to drive the piston rod 11 to extend and drive the squeezing plate 10 to move downward to squeeze the oil-absorbing and hydrophobic sponge 6, thereby squeezing the oil absorbed by the oil-absorbing and hydrophobic sponge 6 downward. Through this device, the oil-water mixture in food waste can be quickly and effectively separated from water.
