Description

Technical Field

[0001] This invention relates to the field of kitchen oil-water treatment technology, specifically to an integrated kitchen oil-water separation device. Background Technology

[0002] Kitchen oily wastewater is characterized by high grease content, numerous solid impurities, and complex composition. Direct discharge can easily cause blockages in municipal pipe networks, eutrophication of water bodies, and environmental pollution. This is one of the key environmental remediation areas of focus in the field of water pollution control equipment manufacturing. Currently, most common kitchen oil-water separation equipment on the market is a simple gravity-type grease trap. Its core principle is to utilize the density difference between oil and water to achieve natural separation by having grease float and water sink.

[0003] Existing kitchen oil-water separators require some water to be added to the oil-water separation tank before use. When using the equipment, the oil-water mixture is poured into the filter frame, which intercepts solid waste, while the oil-water mixture enters the separation tank. Due to density differences, grease floats to the top and is discharged through a guide plate, while the water at the bottom is discharged through a drain pipe, thus achieving oil-water separation. However, the filter frame on top of existing kitchen oil-water separators can only filter large solid waste in the oil-water mixture. Tiny particles such as peppercorns and fine sand still pass through the filter holes and enter the separation tank along with the oil and water. These small particles are denser than water, so they settle at the bottom of the separation tank. Over time, these solid particles clog the drain pipe at the bottom of the separation tank. During subsequent cleaning, the water inside the separation tank cannot be discharged through the drain pipe, requiring the user to unclog it. This not only increases the user's maintenance workload but also causes wastewater retention and odor spread due to untimely cleaning, further exacerbating kitchen environmental pollution. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated kitchen oil-water separation device to solve the problem mentioned in the background art where small solid particles clog the waste drain pipe at the bottom of the separation tank. When cleaning the inside of the separation tank later, the water inside the separation tank cannot be discharged through the waste drain pipe, and the user needs to unclog the waste drain pipe. This not only increases the user's maintenance workload, but also causes wastewater retention and odor diffusion due to untimely cleaning, further aggravating the problem of kitchen environmental pollution.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated kitchen oil-water separation device, comprising a cabinet and a filter mechanism disposed on the top of the cabinet, a separation tank fixedly installed at one end inside the cabinet, an installation shell fixedly installed at the bottom of the separation tank, a filter cylinder disposed inside the installation shell, a through hole opened at the top of the filter cylinder, limit strips fixedly installed on both sides of the filter cylinder, and limit grooves opened on both sides of the inner wall of the installation shell, the two limit grooves respectively cooperating with the two limit strips, a sealing cap threadedly connected to one end of the installation shell, a connecting bracket rotatably installed on the side of the sealing cap near the filter cylinder, a pressing mechanism disposed inside the installation shell, and a limit mechanism disposed inside the sealing cap.

[0006] Preferably, the filtration mechanism includes a top cover, which is rotatably connected to the cabinet. The top cover has a garbage disposal port and a collection trough at its two ends, respectively. A filter basket is provided above the collection trough, which is rotatably connected to the top cover. A connecting pipe is connected to the bottom of the collection trough, and the connecting pipe corresponds to the position of the separation bucket.

[0007] Preferably, an L-shaped drainage pipe is fixedly installed at one end of the separation tank, a guide plate is fixedly installed on the top of one side of the separation tank, a waste discharge pipe is connected to the bottom of the mounting shell, and a valve is fixedly installed inside the waste discharge pipe.

[0008] Preferably, the extrusion mechanism includes a threaded rod, the end of which is rotatably connected to the sealing cover, and a connecting post is threaded onto the external thread of the end of the threaded rod near the filter cylinder. The connecting post is slidably connected to the connecting bracket, and an extrusion plate is fixedly installed on the side of the connecting post away from the threaded rod.

[0009] Preferably, two symmetrically arranged inserts are fixedly installed on the side of the filter cartridge near the connecting bracket. The top and bottom of the connecting bracket near the filter cartridge are provided with slots. The two slots cooperate with the two inserts respectively. The ends of the two inserts near the two slots are fitted with fixing bolts.

[0010] Preferably, the limiting mechanism includes a chuck and an annular seat. The chuck is fixedly connected to the connecting bracket. Guide rods are slidably sleeved at both ends of the annular seat. Both guide rods are fixedly installed inside the sealing cover. Multiple evenly distributed guide rods are fixedly installed on one side of the inner wall of the annular seat. A limiting seat is slidably sleeved on the outside of one end of the multiple guide rods. Multiple evenly distributed slots are opened at the end of the limiting seat near the chuck. The multiple slots cooperate with the chuck. Springs are sleeved on the outside of the multiple guide rods. A first transmission assembly is provided at the top and bottom of the annular seat. Two symmetrically arranged second transmission assemblies are provided inside the annular seat.

[0011] Preferably, the first transmission assembly includes a T-shaped plate, which is slidably connected to an annular seat. A push rod is provided on the side of the T-shaped plate away from the annular seat, and the push rod is slidably connected to a sealing cover.

[0012] Preferably, the second transmission assembly includes a transmission groove and a rotating bracket. The transmission groove is located on one side of the connecting column. The rotating bracket has a first groove and a second groove at its two ends. A first transmission rod is movably installed inside the first groove and is fixedly connected to an annular seat. A second transmission rod is movably installed inside the second groove. A transmission arm is fixedly installed outside the second transmission rod and is rotatably connected to the inner wall of the sealing cover. A third transmission rod is fixedly installed at the end of the transmission arm away from the second transmission rod and is slidably installed inside the transmission groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention collects small particles settled at the bottom of the separation tank by installing a filter cylinder. Before treating the wastewater inside the separation tank, the small particle impurities inside the filter cylinder are compressed by a squeezing mechanism, and the space below the through hole is unblocked, allowing the wastewater to be discharged quickly. This solves the problem in the prior art where small particle impurities accumulate at the bottom of the separation tank, causing blockage of the wastewater discharge pipe and requiring the user to unclog the pipe before the wastewater can be discharged. This not only reduces the user's maintenance workload but also avoids further aggravating kitchen environmental pollution, meeting the technological development needs of the field of water pollution environmental protection equipment manufacturing.

[0014] 2. By setting a limiting mechanism, after the sealing cover is removed, the limiting mechanism fixes the angle between the connecting bracket, the filter cylinder and the sealing cover. After the filter cylinder is pulled out, the filter cylinder cannot rotate, thus avoiding the problem that the filter cylinder will rotate freely after being pulled out, causing the through hole to face downwards, and causing small particles of impurities inside the filter cylinder to fall to the ground, increasing the user's maintenance workload.

The top and bottom of the connecting bracket 18 near the filter cartridge 13 are provided with slots 23. The two slots 23 cooperate with the two inserts 22 respectively. The ends of the two inserts 22 near the two slots 23 are fitted with fixing bolts 24.

[0023] The limiting mechanism includes a chuck 25 and an annular seat 26. The chuck 25 is fixedly connected to the connecting bracket 18. Guide rods 27 are slidably sleeved at both ends of the annular seat 26. Both guide rods 27 are fixedly installed inside the sealing cover 17. Multiple evenly distributed guide rods 28 are fixedly installed on one side of the inner wall of the annular seat 26. A limiting seat 29 is slidably sleeved on the outside of one end of the multiple guide rods 28. Multiple evenly distributed slots 30 are opened at the end of the limiting seat 29 near the chuck 25. The multiple slots 30 cooperate with the chuck 25. Springs 31 are sleeved on the outside of the multiple guide rods 28. A first transmission assembly is provided at the top and bottom of the annular seat 26. Two symmetrically arranged second transmission assemblies are provided inside the annular seat 26.

[0024] The first transmission assembly includes a T-shaped plate 32, which is slidably connected to an annular seat 26. A push rod 33 is provided on the side of the T-shaped plate 32 away from the annular seat 26, and the push rod 33 is slidably connected to the sealing cover 17.

[0025] The second transmission assembly includes a transmission groove 34 and a rotating bracket 35. The transmission groove 34 is located on one side of the connecting column 20. The rotating bracket 35 has a first groove 36 and a second groove 37 at its two ends. A first transmission rod 41 is movably installed inside the first groove 36 and is fixedly connected to the annular seat 26. A second transmission rod 38 is movably installed inside the second groove 37 and a transmission arm 39 is fixedly installed outside the second transmission rod 38. The transmission arm 39 is rotatably connected to the inner wall of the sealing cover 17. A third transmission rod 40 is fixedly installed at the end of the transmission arm 39 away from the second transmission rod 38 and slides inside the transmission groove 34.

[0026] Working principle: Before use, rotate the threaded rod 19, and the connecting column 20 and the extrusion plate 21 move synchronously. The extrusion plate 21 is located at the end of the filter cylinder 13 away from the sealing cover 17. Then, make the through hole 14 of the filter cylinder 13 face upward, and align the two limiting strips 15 on both sides of the filter cylinder 13 with the two limiting grooves 16 inside the mounting housing 10. Then, push the filter cylinder 13 into the interior of the mounting housing 10. Finally, rotate the sealing cover 17 to complete the sealing connection between the sealing cover 17 and the mounting housing 10. When the 17 is installed outside the mounting shell 10, the mounting shell 10 presses the two push rods 33. The two push rods 33 move towards their respective T-shaped plates 32. The two T-shaped plates 32 move towards the limiting seat 29 at the same time. The limiting seat 29 moves parallel to the corresponding guide rods 28 away from the chuck 25. The limiting seat 29 is retracted into the annular seat 26. At the same time, multiple springs 31 are compressed. At this time, the chuck 25 does not contact the limiting seat 29, so the sealing cover 17 can rotate freely. Then, pour a certain amount of clean water into the separation bucket 7, and place a garbage can below the garbage disposal port 3. Place a collection bucket for collecting oil at the position of the guide plate 9. When in use, pour kitchen garbage into the filter basket 5. The filter basket 5 intercepts solid garbage, while the oil-water mixture falls into the collection tank 4 through the filter holes of the filter basket 5, and then enters the separation bucket 7 through the connecting pipe 6. Then, rotate the filter basket 5 so that the solid garbage inside the filter basket 5 falls into the garbage can below through the garbage disposal port 3. Under the principle of density difference, the water in the lower layer is discharged through the L-shaped drain pipe 8, and the grease in the upper layer is discharged through the guide plate 9, thus achieving oil-water separation. When some small particles such as peppercorns and fine sand particles pass through the filter holes of the filter basket 5 and enter the separation tank 7 along with the oil and water, the small particles settle at the bottom of the separation tank 7 and enter the filter cylinder 13 through the through hole 14. When the wastewater inside the separation tank 7 needs to be treated, first rotate the threaded rod 19, which drives the connecting column 20 and the extrusion plate 21 to move synchronously to one side of the sealing cover 17. The extrusion plate 21 compresses the small particles inside the filter cylinder 13, and the space below the through hole 14 is cleared. Then, open the valve 12, and the wastewater inside the separation tank 7 enters the filter cylinder 13 through the through hole 14. Finally, it is quickly discharged through the waste discharge pipe 11. This solves the problem in the prior art where small particle impurities accumulate at the bottom of the separation tank 7, causing blockage of the waste discharge pipe 11, requiring the user to clear the wastewater before it can be discharged. This not only reduces the user's maintenance workload but also avoids further aggravation of kitchen environmental pollution, meeting the technical development needs of the water pollution environmental protection equipment manufacturing field. When the threaded rod 19 rotates and drives the extrusion plate 21 to move toward one side of the sealing cover 17, the two second transmission components move synchronously. The movement process of one of the second transmission components is as follows: In the initial state, the transmission rod 3 40 is located at the inclined part of one end of the transmission groove 34. When the connecting column 20 moves with the threaded rod 19, the transmission rod 3 40 moves to the horizontal part of the transmission groove 34. At this time, the transmission arm 39 rotates, which in turn drives the transmission rod 2 38 to rotate. The transmission rod 2 38 moves inside the groove 2 37, which in turn causes the rotating bracket 35 to rotate. The groove 1 36 rotates synchronously with the rotating bracket 35, and the transmission rod 1 41 inside the groove 1 36 moves accordingly. The movement process of the other second transmission component is the same as above. The two transmission rods 1 41 move synchronously and push the annular seat 26. The annular seat 26 moves horizontally toward the chuck 25 along the two guide rods 1 27. After the wastewater inside the separator 7 is discharged, the sealing cover 17 is rotated in the reverse direction. After the sealing cover 17 is separated from the mounting housing 10, the limiting seat 29 moves towards the chuck 25 under the action of multiple springs 31. At this time, the chuck 25 is engaged in multiple slots 30, and the angle between the connecting bracket 18 and the filter cylinder 13 is fixed. After the filter cylinder 13 is pulled out, the filter cylinder 13 cannot rotate, thus avoiding the problem that the filter cylinder 13 will rotate freely after being pulled out, causing the through hole 14 to face downwards, and causing small particles of impurities inside the filter cylinder 13 to fall to the ground, increasing the user's maintenance workload.
