Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation, in particular to an oil-water separation device for a kitchen sink. Background Art

[0002] In modern catering and daily life, the wastewater discharged from the kitchen sink often contains a large amount of grease and food residues. If these oily wastewaters are discharged directly into the sewer without treatment, it will not only easily cause sewer blockage and increase cleaning and maintenance costs, but may also cause environmental pollution. Therefore, it is necessary to separate the oily wastewater from water.

[0003] For example, patent publication number CN116078045 A discloses an oil-water separation treatment device for a kitchen. The device divides the area in the separation box into a primary separation zone, a secondary separation zone and a tertiary separation zone by arranging four partitions in the separation box. The primary separation zone can intercept solid impurities very finely and discharge impurities well by means of a separation filter etc. The secondary separation zone can effectively precipitate the remaining impurities etc. by means of the partitions etc., and can also discharge them conveniently. The tertiary separation zone can realize oil-water separation by floating the oil on the upper layer after standing still through the principle of oil-pollution separation, and then discharge the upper water through the overflow pipe. The overall structure is easy to use, reliable and stable.

[0004] When using the above device, during the standing process of the oil and water in the upper device, due to the uncertainty of the use time of the kitchen sink, the oil and water in the sink will move to the separation device due to use, which will affect the original standing effect of the oil and water, increase the time originally needed to achieve standing separation, and cause the oil-water separation efficiency to become lower.

[0046] The collecting assembly 12 includes a collecting cylinder 1201, the outer wall of the collecting cylinder 1201 is threadedly connected to the box body 1, the collecting cylinder 1201 is internally slidably connected with a placing plate 1202, a No. 1 spring 1203 is fixedly connected between the placing plate 1202 and the collecting cylinder 1201, a toothed part 1204 is fixedly connected to the bottom end of the placing plate 1202, a limiting part 1205 is internally slidably connected to the collecting cylinder 1201, and a No. 2 spring 1206 is fixedly connected between the limiting part 1205 and the collecting cylinder 1201.

[0047] The oil-water mixture in the kitchen sink can be moved to the position of the filter cartridge 2 of the housing 1 through a set water pipe, the oil and water are moved to the inside of the sieve drum frame 301, the oil and water are moved to the outer area of ​​the filter cartridge 2 through the sieve drum frame 301 and the filter cartridge 2, the outer area of ​​the filter cartridge 2 is moved to the static area through the oil-water buffer, the dynamic separation layer structure is in the area to be static, the oil and water in the area to be static are moved to the dynamic separation layer structure, the static state is completed, and the oil-water separation is achieved.

[0048] The output end of the No. 1 motor 303 rotates, the sleeve 304 and the limiting frame 307 rotate, and the transmission rod 308 rotates through the transmission of the No. 1 gear member 311, the transmission gear member 312 and the No. 2 gear member 313. The output end of the No. 1 motor 303 rotates, the sleeve 304 rotates, and the crank 305 rotates through the transmission of the main bevel wheel 309 and the slave bevel wheel 310. The outer wall of the crank 305 contacts the inner wall of the limiting frame 307, and then the limiting frame 307 and the transmission rod 308 are affected by the rotation of the crank 305, so that the limiting frame 307 and the transmission rod 308 can be moved up and down. Movement, since the top and bottom ends of the limiting frame 307 are rotatably connected to the moving rod 306 and the transmission rod 308 respectively, the position between the limiting frame 307 and the No. 2 transmission component is relatively fixed, and during the up and down movement of the limiting frame 307, the No. 2 transmission component will also move up and down synchronously, and will not affect the transmission effect of the No. 2 transmission component. The output end of the No. 1 motor 303 has a speed limit, and there will be no overspeed. Limiting the output speed of the No. 1 motor 303 can avoid the situation where the service life of the filter component 3 is reduced due to the excessive speed of the filter component 3.

[0049] Therefore, the rotation of the output end of motor No. 1 303 can realize the up and down movement of transmission rod 308 during the rotation process, thereby making the brush member 302 move up and down during the rotation process, and the brush member 302 can clean the inside of the screen drum frame 301, and the outer wall of the screen drum frame 301 is provided with filter holes that can be used for filtering, and the oil and water can move to the outer area of ​​the screen drum frame 301 through the filter holes, and move to the outer wall area of ​​the filter drum 2 through the filter drum 2. Through the setting of transmission assembly No. 1 and transmission assembly No. 2, the output end of motor No. 1 303 rotates, and the crank 305 rotates through the transmission assembly No. 1, thereby making the limiting frame 307 move up and down, and the sleeve 304 rotates, and the limiting frame 307 rotates through the transmission assembly No. 2, thereby making the limiting frame 307 move up and down during the rotation process, thereby making the brush member 302, the spiral conveying rod 314 and the push rod 315 move up and down during the rotation process, thereby ensuring the feasibility of the filter assembly 3.

[0050] The spiral conveying rod 314 moves up and down during the rotation, so that impurities can be moved to the collecting barrel 1201. When the impurities are compressed, the oil and water are easily squeezed out when compressed, and then moved to other positions. The impurities in the collecting barrel 1201 will be on the placement plate 1202. The push rod 315 moves up and down, and applies force to the placement plate 1202 through the impurities, so that the placement plate 1202 moves, the No. 1 spring 1203 is compressed, and the toothed part 1204 moves. During the movement of the toothed part 1204, the limiting part 1205 moves due to the tooth shape of the toothed part 1204, and the No. 2 spring 1206 is compressed. Due to the tooth shape of the toothed part 1204 and the action of the No. 2 spring 1206, the limiting part 1205 limits the toothed part 1204, so that the toothed part 1204 can only move in a single direction.

[0051] After the collection is completed, the collection cylinder 1201 is rotated to take the collection cylinder 1201 out of the box body 1. After the impurities in the collection cylinder 1201 are taken out, the limiting member 1205 is manually moved to separate the limiting member 1205 and the toothed member 1204. At this time, the placement plate 1202 will return to the original position under the action of the No. 1 spring 1203. Through the setting of the filter component 3, the oil and water are initially filtered through the screen drum frame 301, and the filter cylinder 2 can filter the oil and water again. During the filtering of the oil and water, the filter component 3 is used to realize the up and down movement of the brush member 302, the spiral conveying rod 314 and the push rod 315 during the rotation process, and the brush member 302 can realize the cleaning of the inside of the screen drum frame 301. The spiral conveying rod 314 can move the impurities inside the screen drum frame 301 to the collecting drum 1201, and the push rod 315 moves the placement plate 1202 through the impurities, thereby moving the placement plate 1202, thereby cleaning the screen drum frame 301 and moving the impurities, ensuring the filtering effect. The impurities are on the placement plate 1202, and the push rod 315 applies force to the placement plate 1202 through the impurities during the up and down movement process, thereby moving the placement plate 1202. The limiting member 1205 and the No. 2 spring 1206 make the placement plate 1202 only move in one direction. As the placement plate 1202 moves, the internal volume of the collecting drum 1201 becomes larger, and the collection of impurities is completed, thereby ensuring the practicability of the separation device.

[0052] The partition plate 10, the tank body 4 and the piston member 11 form a space with a variable volume. The telescopic end of the No. 1 telescopic member 901 contracts, so that the turntable 902 and the limiting block 904 contact and the piston member 11 moves, and the volume of the space becomes larger, so that the oil and water outside the tank body 4 move into the space through the one-way valve, and the push rod 903 moves upward, and the push rod 903 contacts the bottom of the rotating ring 804, and the rotating ring 804 and the moving platform 802 move upward. The No. 3 spring 803 is compressed. Since the limiting rod 806 will move along the track groove of the outer wall of the moving track tube 805, the track of the outer wall of the moving track tube 805 is set, when the limiting rod 806 moves upward to the maximum height, the telescopic end of the No. 1 telescopic member 901 is extended, and the rotating ring 804, the push rod 903 and the limiting rod 806 move downward. Move, the outer wall of the moving track cylinder 805 causes the limiting rod 806 to rotate during the descent process, and then the rotating ring 804 and the telescopic part No. 1 901 rotate, so that the telescopic part No. 1 901 rotates to another space with a variable volume, and the oil and water in the original space are initially stationary. At the same time, the turntable 902 rotates to the limiting block 904. At this time, the telescopic end of the telescopic part No. 1 901 continues to extend, and the turntable 902 moves the piston part 11, so that the space becomes smaller, and then the oil and water inside the space are moved to another area through the water outlet of the tank body 4 and the connecting pipe 6. The oil and water in another area can enter the container 501 through the water inlet hole of the container 501. When injecting oil and water into another area through the connecting pipe 6, the speed of injecting oil and water is controlled to avoid excessive speed affecting the static state of the oil and water in another area.

[0053] When the oil and water entering the container 501 are at rest, the water inlet of the container 501 is closed to prevent the outside area from affecting the oil and water inside the container 501. The detection device can detect the liquid level height inside the container 501 in real time, and adjust the position of the movable plate 502 through the second telescopic member 504 according to the liquid level height. The electrically controlled ventilation device includes an exhaust hole. The exhaust hole is opened at the top of the movable plate 502. An electrically controlled valve for controlling the opening or closing of the exhaust hole is installed at the exhaust hole position. The electrically controlled valve opens the exhaust hole of the movable plate 502 to facilitate the entry of liquid. The second telescopic member 504 makes the height of the movable plate 502 higher than the liquid level height inside the container 501, so as to prevent the liquid from flowing out of the exhaust hole of the movable plate 502. After the rest is completed, the exhaust hole is opened through the water outlet end of the container 501. The second telescopic member 504 pushes the movable plate 502 to move and discharge the water at the bottom. The density of the partition plate 503 is between water and oil, so that after the standing is completed, the partition plate 503 is between water and oil. Therefore, when the partition plate 503 contacts the bottom surface of the container 501, the water is discharged at this time, and the oil is discharged later, thereby realizing the separation of oil and water. Through the setting of the oil-water buffer, when the water tank is in use, the oil and water are moved to the standing area through the oil-water buffer, and the oil-water buffer performs preliminary standing of the oil and water to avoid the high-flow rate of oil and water affecting the originally standing oil and water, thereby affecting the original standing effect of the oil and water, and the discharge end of the oil-water buffer is slowly moved to the standing area to ensure the standing separation of the oil and water, and the preliminary standing and standing before separation of the oil and water are realized, thereby improving the oil-water separation efficiency.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
