Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a floating oil purification tank. Background Art

[0002] The oil slick purification tank is a device specially designed to separate and remove oil from water bodies. It is widely used in industrial wastewater treatment, marine oil pollution emergency treatment, and kitchen wastewater treatment in the catering industry. Its main function is to efficiently separate and recover oil substances floating on the water surface from the water to protect the environment from oil pollution and realize the resource recycling of oil products. The oil slick purification tank uses the natural characteristics of the difference in oil and water density to collect the oil layer floating on the water surface through physical means. If the oil slick is discharged directly into natural water bodies, it will seriously affect the water quality and ecosystem. Oil substances will cover the water surface, hinder the exchange of oxygen, cause aquatic plants and animals to die of hypoxia, and destroy the ecological balance.

[0003] A purification pool for removing floating oil, with Chinese patent application number 202222514748.6, includes an oil retaining weir, an oil discharge pipe, and a pool wall. The oil retaining weir is located on the inner side of the pool wall, and the oil retaining weir encloses an oil retaining area, and a clear water area is formed between the pool wall and the oil retaining weir. One end of the oil discharge pipe is located at the upper part of the oil retaining area, and the other end is connected to the outside world for discharging the floating oil in the oil retaining area; the oil retaining area is connected to the bottom of the clear water area. Sewage continuously enters from the bottom of the purification pool and fills the entire purification pool. Since the dirty oil in the sewage will surge upward after entering from the bottom of the purification pool, the oil retaining weir collects the dirty oil in the oil retaining area. Since the dirty oil floats on the water surface, and the oil retaining area is connected to the bottom of the clear water area, the dirty oil can be kept in the oil retaining area, and the sewage from which the dirty oil is removed enters the clear water area; since the dirty oil forms floating oil on the sewage surface in the oil retaining area, the oil discharge pipe can discharge the floating oil from the purification pool.

[0004] During use, the existing floating oil purification tank is not convenient for dynamically pushing the oil-water mixture inside the purification tank, and it is difficult to adjust the volume of the sedimentation space inside the purification tank according to the characteristics of the oil-water mixture, thereby reducing the purification and separation efficiency of the oil-water mixed wastewater.

[0023] Beneficial effects of the present invention:

[0024] 1. The present invention can facilitate oil-water separation of wastewater containing floating oil by setting a baffle separation mechanism. The first baffle and the push flow plate first block the wastewater in the liquid inlet chamber, so that the wastewater slowly enters the separation chamber for sedimentation. By utilizing the principle of gravity sedimentation, the slag and water sink because their density is greater than that of the oil, and the floating oil continues to rise and enters the oil collecting chamber through the second baffle, thereby improving the separation effect.

[0025] 2. The present invention can also dynamically promote the flow of wastewater by setting a baffle separation mechanism, avoid stagnation or too slow flow rate in local areas, and ensure that oil, water and slag are continuously in an effective separation environment. Especially when dealing with oil-water mixtures with high viscosity or containing a large amount of solid impurities, this design helps to reduce blockage, accelerate the separation process, and improve separation efficiency. During dynamic promotion, the piston rod of the first hydraulic cylinder is extended and retracted to drive the lifting member to move, and the lifting member drives the connecting rope to move when it moves up and down, so that the push flow plate rotates left and right. During the rotation process, the flow speed of the wastewater in the liquid chamber to the separation chamber is accelerated, and when the push flow plate rotates to the left, the first rotating member drives the first The left end of the spring rotates upward, and the first spring drives the left end of the connecting rod to move downward through the second rotating member, so that the right end of the connecting rod rotates upward, and the connecting rod rotates around the limit rod and drives the inclined rod to tilt to the upper left. During the tilting process, it slides at the bottom of the sliding seat and drives the second baffle to move upward. The second baffle stretches the second spring and blocks the floating oil in the inner cavity of the oil collecting chamber to prevent the floating oil in the inner cavity of the oil collecting chamber from flowing back into the separation chamber. When the push plate rotates to the right to push the waste water, the first spring is reset, so that the connecting rod, the inclined rod and the sliding seat are reset synchronously. At this time, the second spring drives the second baffle to retract into the frame, so that the floating oil can pass smoothly through the top of the second baffle.

[0026] 3. The present invention can drive the sliding part to slide left and right on the top of the purification tank body by setting a second hydraulic cylinder. The sliding part drives the first baffle to slide in the inner cavity of the purification tank body, thereby changing the space ratio between the liquid inlet cavity and the separation cavity. By adjusting the ratio of the two cavities, the separation efficiency can be optimized according to the characteristics of the actual oil-water mixture being treated. For mixtures with high oil content or that require longer sedimentation time, the space of the separation tank can be increased to provide more time and space for oil-water separation, and vice versa.

[0027] 4. The present invention provides a basket filter mechanism, which can facilitate filtering of large particle residues in the wastewater entering the liquid inlet chamber. After the wastewater enters the first filter frame and the second filter frame, the filter screens at the bottom of the first filter frame and the second filter frame block the residue. When the interior of the basket filter mechanism needs to be cleaned, the limit pin is rotated ninety degrees so that the clamping head and the socket on the surface are aligned. Then the limit pin is removed from the first baffle, the second clamping seat and the socket on the second filter frame, the second clamping seat is moved upward, the second clamping seat is removed from the top of the first baffle, the first clamping seat is moved upward, and the first clamping seat is removed from the top of the septic tank body, thereby realizing disassembly and cleaning of the first filter frame and the second filter frame. When the position of the first baffle changes, the first baffle drives the second filter frame to move through the second clamping seat, and the rod body on the second filter frame slides inside the slide groove to change the extension length of the second filter frame, so that the basket filter mechanism can adapt to liquid inlet chambers of different spatial volumes.

[0028] 5. The present invention can facilitate the discharge of water and slag accumulated at the bottom of the separation chamber by arranging a collecting mechanism. The water and slag enter the inner cavity of the collecting cylinder through the feed port. The output shaft of the reduction motor drives the spiral rod to rotate, so that the water and slag enter the filter cylinder. The water is discharged through the filter holes on the filter cylinder, and the slag enters the discharge head. When there is too much slag, the discharge head will be pushed forward, and the discharge head will drive the sliding rod to slide inside the support plate and compress the third spring. When the discharge port is separated from the inner cavity of the filter cylinder, the slag is discharged through the discharge port. When the slag is discharged, the third spring drives the discharge head to reset and continue to block the slag.

[0029] 6. The present invention can facilitate secondary separation of floating oil in the inner cavity of the oil collecting chamber through the coordinated use of an oil discharge mechanism and an electromagnetic separator. First, a high-frequency coil establishes a high-frequency electric field. The dielectric constants of oil and water are different, which means that their behaviors in the electric field will be different. In the high-frequency electric field, oil droplets are more easily attracted or repelled by the electric field than water due to their lower dielectric constant, thereby changing the movement trajectory or aggregation form, so that the floating oil is adsorbed around the shell, and the spiral rod drives the driving wheel to rotate. The driving wheel drives the driven wheel and the center rod to rotate through the transmission belt. The center rod drives several floating oil collection containers to rotate. The floating oil collection container collects the floating oil through the collection groove inside it and transports it to the top of the oil discharge hopper. The liquid pump at the bottom of the oil discharge hopper extracts the water at the bottom of the inner cavity of the oil collecting chamber and transports it to the oil-water separator driven by the coalescence separation filter element to remove the trace floating oil in the water.

DETAILED DESCRIPTION

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] Embodiment 1, as Figure 1-14 As shown, this embodiment provides a floating oil purification tank, including a purification tank body 100, a liquid inlet chamber 101 is provided on the left side of the inner cavity of the purification tank body 100, a separation chamber 102 connected to the liquid inlet chamber 101 is provided at the middle end of the inner cavity of the purification tank body 100, and an oil collecting chamber 103 connected to the separation chamber 102 is provided on the right side of the inner cavity of the purification tank body 100.

[0047] It also includes a baffle separation mechanism 200, which is installed in the inner cavity of the purification tank body 100. The baffle separation mechanism 200 includes a first baffle plate 201 and a second baffle plate 212. The bottom of the first baffle plate 201 is rotatably connected to a push plate 215, and the surface of the second baffle plate 212 is movably sleeved with a frame body 211.

[0048] By setting up the baffle separation mechanism 200, it is possible to facilitate oil-water separation of wastewater containing floating oil. The first baffle plate 201 and the push flow plate 215 first block the wastewater in the inner cavity of the liquid inlet chamber 101, so that the wastewater slowly enters the separation chamber 102 for sedimentation. By utilizing the principle of gravity sedimentation, the slag and water sink because their density is greater than that of the oil, and the floating oil continues to rise and enters the oil collecting chamber 103 through the second baffle plate 212, thereby improving the separation effect.

[0049] The first baffle 201 and the flow-pushing plate 215 are movably connected to the inner wall of the purification tank body 100, and the sliding parts 204 are fixedly connected to the front and rear sides of the top of the first baffle 201, and the sliding parts 204 are movably mounted on the top of the purification tank body 100. The second hydraulic cylinder 205 is fixedly installed on the left side of the sliding part 204, and the second hydraulic cylinder 205 is fixedly connected to the front and rear sides of the purification tank body 100. The first hydraulic cylinder 214 is fixedly connected to the front and rear sides of the right side of the first baffle 201, and the piston rod of the first hydraulic cylinder 214 is fixedly connected to the lifting member 202, and the lifting member 202 is slidably connected to the right side of the first baffle 201. The top of the lifting member 202 is fixedly connected to the connecting rope 203, and the end of the connecting rope 203 away from the lifting member 202 is fixedly connected to the bottom of the left side of the flow-pushing plate 215.

[0050] The right bottom of the push plate 215 is rotatably connected to the first rotating member 206, one end of the first rotating member 206 is fixedly connected to the first spring 207, one end of the first spring 207 is rotatably connected to the second rotating member 208, one end of the second rotating member 208 is rotatably connected to the connecting rod 209, the center of the connecting rod 209 is rotatably connected to the limiting rod 213, the front and rear ends of the limiting rod 213 are fixedly connected to the inner wall of the purification tank body 100, the right end of the connecting rod 209 is fixedly connected to the inclined rod 210, the top of the inclined rod 210 is slidably connected to the sliding seat 216, the sliding seat 216 is fixedly connected to the left side of the second baffle 212, a plurality of second springs 217 are fixedly connected to the bottom of the inner cavity of the frame 211, the top of the second spring 217 is fixedly connected to the bottom of the second baffle 212, and the frame 211 is fixedly installed inside the purification tank body 100.

[0051] The connecting rope 203 passes around the top of the first baffle 201 , and a pulley for guiding the connecting rope 203 is provided on the top of the first baffle 201 .

[0052] By setting up the deflection separation mechanism 200, the flow of wastewater can be dynamically promoted to avoid stagnation or slow flow in local areas, ensuring that oil, water and residue are continuously in an effective separation environment. Especially when dealing with oil-water mixtures with high viscosity or containing a large amount of solid impurities, this design helps to reduce blockage, accelerate the separation process, and improve separation efficiency. During dynamic pushing, the piston rod of the first hydraulic cylinder 214 is extended and retracted to drive the lifting member 202 to move, and the lifting member 202 drives the connecting rope 203 to move when it moves up and down, so that the push plate 215 rotates left and right. During the rotation process, the flow speed of the wastewater in the inner cavity of the liquid inlet chamber 101 to the separation chamber 102 is accelerated, and when the push plate 215 rotates to the left, the left end of the first spring 207 is driven to rotate upward through the first rotating member 206, and the first spring 207 is driven by the first rotating member 206 to rotate upward. The second rotating member 208 drives the left end of the connecting rod 209 to move downward, so that the right end of the connecting rod 209 rotates upward, and the connecting rod 209 rotates around the limit rod 213 and drives the inclined rod 210 to tilt to the upper left. During the tilting process, it slides at the bottom of the sliding seat 216 and drives the second baffle 212 to move upward. The second baffle 212 stretches the second spring 217 and blocks the floating oil in the inner cavity of the oil collecting chamber 103 to prevent the floating oil in the inner cavity of the oil collecting chamber 103 from flowing back into the separation chamber 102. When the push plate 215 rotates to the right to push the wastewater, the first spring 207 is reset, so that the connecting rod 209, the inclined rod 210, and the sliding seat 216 are reset synchronously. At this time, the second spring 217 drives the second baffle 212 to retract into the frame 211, so that the floating oil can pass smoothly through the top of the second baffle 212.

[0053] By setting up a second hydraulic cylinder 205, the sliding member 204 can be driven to slide left and right on the top of the purification tank body 100. The sliding member 204 drives the first baffle 201 to slide in the inner cavity of the purification tank body 100, thereby changing the space ratio between the liquid inlet cavity 101 and the separation cavity 102. By adjusting the ratio of the two cavities, the separation efficiency can be optimized according to the characteristics of the actual oil-water mixture being treated. For mixtures with high oil content or that require longer sedimentation time, the space of the separation tank can be increased to provide more time and space for oil-water separation, and vice versa.

[0054] The utility model further comprises a basket filter mechanism 300 , which is sleeved on the top of the purification tank body 100 and the baffle separation mechanism 200 .

[0055] The basket filter mechanism 300 includes a first filter frame 301 and a second filter frame 305. The surface of the second filter frame 305 is slidably connected to the inner wall of the first filter frame 301. A first clamping seat 302 is fixedly connected to the left side of the first filter frame 301. The first clamping seat 302 is movably mounted on the top of the first filter frame 301. A second clamping seat 304 is fixedly connected to the top of the second filter frame 305. The second clamping seat 304 is mounted on the top of the first baffle 201. A limit pin 303 is provided on the second clamping seat 304. The limit pin 303 passes through the first baffle 201, the second clamping seat 304 and the second filter frame 305 respectively.

[0056] The second filter frame 305 is fixedly connected with a rod body 306 . The first filter frame 301 is provided with slide grooves 307 on both the front and rear sides. Both the front and rear ends of the rod body 306 extend to the inner cavity of the slide groove 307 and are slidably connected with the inner wall thereof.

[0057] By setting up the basket filter mechanism 300, it is convenient to filter the large particle residue in the wastewater entering the liquid inlet chamber 101. After the wastewater enters the first filter frame 301 and the second filter frame 305, the filter screens at the bottom of the first filter frame 301 and the second filter frame 305 block the residue. When it is necessary to clean the inside of the basket filter mechanism 300, the limit pin 303 is rotated ninety degrees so that the clamp head and the socket on the surface are aligned, and then the limit pin 303 is taken out from the first baffle plate 201, the second clamp seat 304 and the socket on the second filter frame 305, and the second clamp seat 304 is moved upward. Take out the second holder 304 from the top of the first baffle plate 201, move the first holder 302 upward, and remove the first holder 302 from the top of the purification tank body 100 to achieve disassembly and cleaning of the first filter frame 301 and the second filter frame 305. When the position of the first baffle plate 201 changes, the first baffle plate 201 drives the second filter frame 305 to move through the second holder 304, and the rod body 306 on the second filter frame 305 slides inside the slide groove 307 to change the extension length of the second filter frame 305, so that the basket filter mechanism 300 can adapt to the liquid inlet cavity 101 of different spatial volumes.

[0058] The first baffle plate 201 , the second holder 304 and the second filter frame 305 are provided with plug holes for use with the limit pin 303 , and the limit pin 303 has clamping heads at both the upper and lower ends on the left side of the surface.

[0059] The collecting mechanism 400 is also included. The collecting mechanism 400 is installed at the bottom of the inner cavity of the purification tank body 100. The collecting mechanism 400 includes a collecting cylinder 401 located on the left side of the frame 211. The inner cavity of the collecting cylinder 401 is rotatably connected to a spiral rod 405.

[0060] The rear end of the spiral rod 405 passes through the purification tank body 100 and is fixedly connected to the reduction motor 406. The reduction motor 406 is fixedly installed on the rear side of the purification tank body 100. The front end of the collecting cylinder 401 passes through the purification tank body 100 and is fixedly connected to the filter cylinder 404. A plurality of filter holes 410 are arranged around the filter cylinder 404. A discharge head 407 is slidably connected to the inner wall of the filter cylinder 404. A discharge port 411 is arranged at the bottom of the discharge head 407. A sliding rod 408 is fixedly connected to the front end of the discharge head 407. A support plate 403 is movably sleeved on the surface of the sliding rod 408. A plurality of third springs 409 are installed around the opposite side of the support plate 403 and the discharge head 407. A fixing rod 402 is fixedly connected to the front end of the support plate 403. The rear end of the fixing rod 402 is fixedly connected to the front side of the purification tank body 100.

[0061] The collecting cylinder 401 is provided with a feed inlet.

[0062] By setting up the collecting mechanism 400, it is possible to facilitate the discharge of water and slag accumulated at the bottom of the inner cavity of the separation chamber 102. The water and slag enter the inner cavity of the collecting cylinder 401 through the feed port, and the output shaft of the reduction motor 406 drives the screw rod 405 to rotate, so that the water and slag enter the filter cylinder 404, and the water is discharged through the filter hole 410 on the filter cylinder 404, and the slag enters the discharge head 407. When there is too much slag, the discharge head 407 will be pushed forward, and the discharge head 407 drives the sliding rod 408 to slide inside the support plate 403 and compresses the third spring 409. When the discharge port 411 is separated from the inner cavity of the filter cylinder 404, the slag is discharged through the discharge port 411.
