Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil-water separation, in particular to a high-efficiency intelligent oil-water separation tank. BACKGROUND

[0002] The horizontal oil-water separation tank is a device for separating oil from oil-containing sewage, which is usually long-shaped and composed of an end cover, a horizontal circular or elliptical tank wall and a saddle, aiming to efficiently and stably separate oil and water, and is widely used in sewage treatment in factories, mines, ports, terminals and oil depots.

[0004] However, when the above-mentioned separation tank separates, it is difficult to ensure that the oil-water mixture fills the entire tank body, and when the amount of oil liquid introduced is small, the liquid level of the mixture is lower than the oil discharge port, which prevents complete separation of the oil liquid. Furthermore, the position and size of the baffle in the above-mentioned separation tank are fixed, which results in fixed flow of the mixture in the tank body and fixed flow path. When the flow is too large, the oil liquid cannot be separated quickly, and when the flow is too small, the separation efficiency is reduced, making it difficult to achieve efficient oil-water separation.

[0035] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0036] First embodiment

[0037] As Figures 1-11 shown, the high-efficiency intelligent oil-water separation tank of the first embodiment of the present application comprises:

[0038] A separation shell 1 is horizontally arranged, and a liquid inlet 111 is arranged on the separation shell 1. A water outlet 112 and an oil outlet 142 are arranged at the bottom and the top of the separation shell 1 respectively, and the water outlet 112 and the oil outlet 142 are connected with a water valve 131 and an oil valve 143 respectively. The liquid inlet 111, the water outlet 112 and the oil outlet 142 are all in communication with the inner cavity of the separation shell 1.

[0039] A flow guide assembly is arranged along the length direction of the separation shell 1, which comprises fixed flow guide units 2 and movable flow guide units 3. The fixed flow guide units 2 comprise an upper baffle 21 and a lower baffle 22 which are fixedly connected with the inner top wall and the inner bottom wall of the separation shell 1 respectively. A turbulence interval 23 is arranged between the upper baffle 21 and the lower baffle 22. An upper through slot recess 211 and a lower through slot recess 221 are arranged at the top of the upper baffle 21 and the bottom of the lower baffle 22 respectively. The movable flow guide units 3 comprise a floating baffle 5 which moves in the vertical direction in the separation shell 1 and side baffles 4 which are attached to the two sides of the floating baffle 5 and are fixedly connected with the inner side walls of the separation shell 1. The side baffles 4 and the floating baffle 5 and the inner walls of the separation shell 1 form an upper turbulence port 31 and a lower turbulence port 32 which are located above and below the turbulence interval 23 respectively.

[0040] When the device is used, oil-water mixed liquid (hereinafter referred to as “mixed liquid”) is introduced into the horizontal separation shell 1 through the liquid inlet 111. After entering the inside of the separation shell 1, the oil liquid is guided by the flow guide assembly, bypasses the upper and lower sides of the floating baffle 5, i.e. passes through the upper turbulence port 31 and the lower turbulence port 32, and then passes through the turbulence interval 23 between the upper baffle 21 and the lower baffle 22. Then, the mixed liquid passes through the upper and lower sides of the next floating baffle 5. In this way, the mixed liquid is divided into two routes, and the upper and lower routes of the mixed liquid flow in a serpentine manner in the upper and lower parts of the separation shell 1 respectively, which increases the length of the flow path and makes the water with a larger density in the mixed liquid sink to the bottom and the oil with a smaller density rise to the upper part. After opening the oil valve 143, the oil liquid in the upper part is discharged through the oil outlet 142, and then the oil valve 143 is closed. Then, the water valve 131 is opened, and the water with a larger density is discharged from the bottom of the separation shell 1. In this way, the oil-water separation is completed efficiently and thoroughly.

[0041] The specific structure of the separation shell 1 in the embodiment is as shown in Figures 1-5As shown, the separation shell 1 comprises a horizontal tank body 11, the two ends of the tank body 11 are fixed with supports 18, the tank body 11 is supported above the ground through the supports 18; three drainage openings 112 are arranged on the bottom of the tank body 11 and are equidistantly distributed along the length direction of the tank body 11, the drainage openings 112 are connected with drainage pipes 13, and drainage valves 131 are arranged on the drainage pipes 13; a liquid inlet 111 is arranged at one end of the tank body 11, the liquid inlet 111 is connected with a liquid inlet pipe 12, and a liquid inlet valve 121 is arranged on the liquid inlet pipe 12; two oil bags 14 are fixedly arranged at the top of the tank body 11 at positions adjacent to the two ends, the top of the oil bag 14 is provided with a cover plate 141, the bottom of the side wall of the two oil bags 14 is provided with an oil outlet 142, and a cross pipe 19 is communicated between the two oil outlets 142, the middle part of the cross pipe 19 is fixedly communicated with an oil outlet pipe 149, and an oil outlet valve 143 is arranged on the oil outlet pipe 149.

[0042] Different from the fixed position and size baffle in the prior art, in the embodiment, the movable flow guide unit 3 mainly comprises two side baffles 4 and a floating baffle 5 located between the two side baffles 4, the thickness directions of the side baffles 4 and the floating baffle 5 and the thickness directions of the upper baffle 21 and the lower baffle 22 in the fixed flow guide unit 2 are all parallel to the length direction of the separation shell 1, one side of the side baffle 4 away from the floating baffle 5 is fixed to the inner side wall of the tank body 11, and the other side is sealingly attached to the side wall of the floating baffle 5, the floating baffle 5 can move vertically according to the liquid level in the tank body 11, so that the top of the floating baffle 5 is always below the liquid level before oil separation, so that the upper part of the mixed liquid can enter the turbulence interval 23 between the upper baffle 21 and the lower baffle 22 through the upper turbulence opening 31.

[0043] The top of the upper baffle 21 is provided with an upper through groove recess 211, the two ends of the upper through groove recess 211 respectively extend to the opposite two faces of the upper baffle 21, so as to facilitate the mutual communication of the oil in the upper part of the mixed liquid in the tank body 11, enter the oil bag 14, and then be discharged from the oil outlet 142 of the oil bag 14, and then be discharged in turn through the cross pipe 19 and the oil outlet pipe 149; correspondingly, the bottom of the lower baffle 22 is provided with a lower through groove recess 221, the two ends of the lower through groove recess 221 respectively extend to the opposite two faces of the lower baffle 22, so as to facilitate the mutual communication of the sewage in the lower part of the mixed liquid in the tank body 11, and be discharged to the outside through the drainage pipe 13 through the drainage opening 112.

[0044] Further improvement is that the floating baffle 5 is provided with an adjustable aperture adjusting through hole 33.

[0045] By setting the adjusting through hole 33, it is convenient for part of the mixed liquid to pass through the adjusting through hole 33 along the length direction of the tank body 11. By changing the aperture of the adjusting through hole 33, the flow rate of the mixed liquid can also be adjusted. Specifically, when the aperture of the adjusting through hole 33 is reduced, the resistance of the mixed liquid passing through the floating baffle 5 can be increased, thereby reducing the flow rate and flow of the mixed liquid. When the aperture of the adjusting through hole 33 is increased, the resistance of the mixed liquid passing through the floating baffle 5 can be reduced, thereby increasing the flow rate and flow of the mixed liquid.

[0046] Further improvement is that the floating baffle 5 is provided with mounting through holes, the circumferential inner wall of the mounting through holes is provided with a closed loop-shaped air bag 53, the adjusting through hole 33 is formed on the inner side of the air bag 53, and the air pump 6 is arranged outside the separation shell 1 and communicates with the air bag 53.

[0047] By setting the above structure, the air pump 6 is used to draw air from the outside and send it into the air bag 53, so that the air bag 53 expands at the same time, and the aperture on the inner side of the air bag 53, that is, the aperture of the adjusting through hole 33, is reduced. On the contrary, when the air pump 6 draws air from the air bag 53 and discharges it into the outside, the air bag 53 contracts, so that the aperture on the inner side of the air bag 53, that is, the aperture of the adjusting through hole 33, is increased. Furthermore, the air bag 53 can also change the density of the floating baffle 5, so that it is between the wastewater and the oil liquid, thereby ensuring that the top of the floating baffle 5 is always below the liquid level of the mixed liquid. In addition, when the mixed liquid in the tank body 11 is less and the liquid level is lower than the oil outlet 142, the air pump 6 inflates the air bag 53 to increase the volume of the air bag 53, thereby occupying part of the space in the tank body 11, so that the overall liquid level of the mixed liquid rises until the oil liquid level is higher than the oil outlet 142, facilitating the discharge of the oil liquid. In specific operation, after the oil liquid at the top of the mixed liquid is discharged through the oil outlet 142, stop inflating the air bag 53, open the drain valve 131, and the remaining water can be discharged from the tank body 11.

[0048] Further improvement is that the mounting through holes are densely arranged on the floating baffle 5, and the air bags 53 are correspondingly arranged on the mounting through holes.

[0049] By adopting the above design, the number of mounting through holes and air bags 53 is increased, which ensures the adjustment ability of the flow rate and flow of the mixed liquid. At the same time, since the number of air bags 53 is increased, the difference in the size change of all air bags 53 after inflation and air extraction is increased, so that more gas can be filled when the mixed liquid in the tank body 11 is less, and the air bag 53 can occupy enough space after inflation to lift the liquid level of the mixed liquid above the oil outlet 142. In order to facilitate assembly, in the embodiment, the mounting through holes and the air bags 53 are arranged in a rectangular array with equal row spacing and column spacing.

[0050] A further improvement is that the floating baffle 5 includes a closed frame 51 and two baffles 52 fixedly connected to the inner wall of the closed frame 51 and facing each other. Each of the two baffles 52 is provided with a shaped through hole 521 and one side of each is provided with a mesh-distributed connecting groove 522. The shaped through holes 521 are interconnected through the connecting groove 522. The shaped through holes 521 on the two baffles 52 are combined to form an installation through hole. An installation tube 531 communicating with its own inner cavity is provided on the outer edge of the airbag 53. The outer edge of the installation tube 531 is fixedly connected to the inner wall of the connecting groove 522 of the two baffles 52.

[0051] The specific structure of the floating baffle 5 is as follows: Figures 9-11 As shown, the floating baffle 5 includes a closed frame 51 and two spoilers 52. The closed frame 51 is a square frame structure, and the spoilers 52 are square plates. The outer circumferential edge of the spoilers 52 is fixedly connected to the inner circumferential wall of the closed frame 51. The two spoilers 52 are arranged opposite each other and are sealed together. Each of the two spoilers 52 is provided with a rectangular array of shaped through holes 521 extending along its own thickness direction. The side of the two spoilers 52 that is sealed together is provided with a mesh-like array of connecting grooves 522. The connecting grooves 522 connect adjacent shaped through holes 521. Four connecting grooves 522 are arranged in a ring array on the inner circumferential wall of the shaped through holes 521. The connecting grooves 522 are arc-shaped grooves. Four mounting tubes 531 are distributed on the outer circumferential edge of the airbag 53. The outer diameter of the mounting tubes 531 is the same as the inner diameter of the connecting grooves 522.

[0052] With the above structure, during assembly, each airbag 53 is inserted into the molded through hole 521 on one of the spoilers 52, so that the four mounting tubes 531 on the outside of the airbag 53 are respectively inserted into the four connecting grooves 522 on the outside of the corresponding molded through hole 521. Then, the other spoiler 52 is covered, so that the two spoilers 52 face each other. This ensures that the molded through holes 521 on the two spoilers 52 combine to form a mounting through hole, and the openings of the connecting grooves 522 on the two spoilers 52 overlap and the two connecting grooves 522 combine to form a connecting channel that is sealed to the outer circumferential edge of the mounting tube 531. The two spoilers 52 are placed inside the closed frame 51. The closed frame 51 can further position the two spoilers 52, ensuring that the outer circumferential edge of the two spoilers 52 is sealed and fitted to the closed frame 51. The two spoilers 52 are set facing each other to ensure the accuracy and sealing of the floating baffle 5 assembly, so that the airbags 53 can communicate with each other.

[0053] Further improvement is that the closed frame 51 and the two spoilers 52 form a communication cavity, the two sides of the closed frame 51 are provided with communication holes 513, the communication holes 513 of the adjacent movable flow guide units 3 are communicated through the communication middle pipe 54, the separation shell 1 is further provided with a corrugated hose 15, one end of the corrugated hose 15 is fixedly connected with the separation shell 1 and communicated with the air pump 6, and the other end is communicated with the communication hole 513 on the closed frame 51 of the end movable flow guide unit 3.

[0054] Specifically, the closed frame 51 includes a frame body 511 and a frame cover 512 fixedly connected, the frame body 511 and the frame cover 512 are closed loop groove structures with the groove opening facing the inside, the two spoilers 52 are clamped between the two side walls of the closed groove, so that the frame body 511, the frame cover 512 and the two spoilers 52 form a communication cavity, the two sides of the frame body 511 and the two sides of the frame cover 512 are provided with communication holes 513, the communication holes 513 are communicated with the communication cavity, and part of the communication groove 522 extends to the circumferential outer edge of the spoiler 52, so that the communication cavity is communicated with the air bag 53 through the mounting pipe 531. The two sides of the frame body 511 and the frame cover 512 are provided with protruding plates 514, and the side baffle 4 is attached between the two protruding plates 514, so as to ensure that the floating baffle 5 can slide in the vertical direction.

[0055] The two communication middle pipes 54 are arranged between the floating baffles 5 of the two adjacent movable flow guide units 3 and are distributed side by side in the horizontal direction and extend along the length direction of the tank body 11. The two ends of the communication middle pipe 54 are communicated with the two communication holes 513 respectively.

[0056] Among the floating baffles 5 of the two movable flow guide units 3 at the end, the two communication holes 513 outside the closed frame 51 are communicated with each other through the communication end pipe 55; the tank body 11 is fixed with a vertical pipe 113 penetrating the top wall of the tank body 11 and extending in the vertical direction, the bottom end of the vertical pipe 113 is communicated with the middle part of the communication end pipe 55 through the corrugated hose 15, the top end of the vertical pipe 113 is communicated with the input end of the air pump 6 through the adjusting air pipe 61, the air pump 6 is fixed above the tank body 11 through the support frame 64, the end of the air pump 6 away from the adjusting air pipe 61 is communicated with the downward filter cover 63, and the bottom of the filter cover 63 is covered with a filter screen 631.

[0057] With the above structure, when the outside air is introduced to inflate the air bag 53, the filter screen 631 below the filter cover 63 can filter out the dust and impurities in the air to ensure clean air. The clean air successively passes through the filter cover 63, the air pump 6, the adjusting air pipe 61, and then enters the vertical pipe 113 to flow downward, passes through the corrugated hose 15, and then enters the communication end pipe 55, and then enters the communication cavity at the end position, and then enters the communication cavity at the middle position through the communication middle pipe 54, and then diffuses into the air bag 53, thereby inflating the air bag 53. When the air in the air bag 53 is pumped out, the air returns along the original path, passes through the communication cavity, the communication middle pipe 54, the communication end pipe 55, the corrugated hose 15, the vertical pipe 113, the adjusting air pipe 61, the air pump 6, and the filter cover 63, and is discharged to the outside.

[0058] Further improvement is that the top of the separation shell 1 is further provided with two balance openings 144 in communication with the outside, and the two balance openings 144 are respectively connected with two one-way valves 145. The inlets of one of the two one-way valves 145 face the outside, and the inlet of the other one-way valve 145 faces away from the outside.

[0059] Specifically, the two balance openings 144 are respectively arranged on the two cover plates 141, and the two balance openings 144 are respectively connected with two one-way valves 145 in opposite directions. The one-way valves 145 are provided with protective covers 148 above.

[0060] With the above structure, the two one-way valves 145 limit the direction of air flow, so that one of them is used for the outside air to enter the tank body 11 through the balance opening 144, and the other one-way valve 145 is used for the air inside the tank body 11 to be discharged to the outside through the balance opening 144, thereby facilitating the stable air pressure inside the tank body 11. The protective covers 148 can protect the one-way valves 145 and the balance openings 144 from being polluted by rainwater and particulate impurities in the air.

[0061] Further improvement is that the sidewall of the separation shell 1 is provided with a viewing port 146, the viewing port 146 is fixed with a viewing window 147, the oil discharge port 142 is located between the top and the bottom of the viewing window 147, and the separation shell 1 is further provided with an indicating element 17 having a density between waste water and waste oil and moving along the vertical direction. The movement path of the indicating element 17 is located within the observation range of the viewing window 147.

[0062] Specifically, a viewing port 146 is located on the side wall of the oil reservoir 14 and is an elongated strip extending vertically. A viewing window 147 is fixed inside the viewing port 146. On the outer side wall of the oil reservoir 14, on both sides of the viewing window 147, there are also scale lines 162 arranged side by side along the vertical direction. A sliding rod 173 extending vertically is fixed inside the oil reservoir 14. The top end of the sliding rod 173 is fixedly connected to the cover plate 141, and the bottom end is fixed with a protrusion 174. The indicator 17 includes two metal plates 171 arranged horizontally along the vertical direction. The two metal plates 171 are fixedly connected by a foam board 172. The metal plates 171 are slidably sleeved on the protrusion 174.

[0063] The foam board 172 and two metal plates 171 can be combined to form an indicator 17 with a density less than water and greater than oil, so that the indicator 17 can be suspended at the interface between oil and water in the mixture. The position of the indicator 17 can be easily observed through the viewing window 147. The oil level can be observed with the scale line 162 to control the air pump 6 to adjust the amount of air in the airbag 53, thereby controlling the shape of the airbag 53 and the height of the mixture.

[0064] A further improvement is that the upper baffle 21 and the lower baffle 22 are each provided with protruding ribs 24 that are closely distributed in the vertical direction and extend in the horizontal direction on the side adjacent to the liquid inlet 111.
