Description

Technical Field

[0001] The present invention relates to the technical field of oil-water treatment, and more specifically, it relates to a short-time forced oil-water separation treatment device with continuous inlet and outlet. Background Art

[0002] Sewage refers to the discharged water from life and production that is contaminated to a certain extent. Water that has lost its original use function is simply called sewage, and oil-water is a type of sewage. Before discharging the oil-water into the environment, the oil and water in the oil-water need to be separated by an oil-water separation treatment device. Existing devices stratify the oil-water by sedimentation and open a control valve for draining water according to the height of the oil-water. When the liquid level of the oil-water mixture drops, the oil on its upper layer will contact the inner wall of the device and move up and down, resulting in oil adsorption. When the liquid level rises, the lower layer of water will submerge the position where the oil is adsorbed, resulting in the continued mixing of oil and water. Moreover, the oil adsorbed on the inner wall of the device cannot be effectively cleaned. Summary of the Invention

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a short-time forced oil-water separation treatment device with continuous inlet and outlet.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A short-time forced oil-water separation treatment device with continuous inlet and outlet, including a cylinder body and a cover body. The cover body is installed at the top of the cylinder body, and a separation component and a cleaning component are installed inside the cylinder body;

[0005] The separation component includes a rotating rod located inside the cylinder body. A sliding member and a pushing member are slidably connected to the outer side wall of the rotating rod. The pushing member is located above the sliding member. Two oil collecting members are fixedly connected to the outer side wall of the sliding member. One side of the oil collecting member is an inclined surface, and a number of oil inlet holes are provided on the inclined surface. A number of oil discharge holes are provided on the inner side wall of the cylinder body. A cylinder is installed at the top of the pushing member;

[0006] The cleaning component includes a column and a mesh cylinder. The column is movably connected to the bottom of the oil collecting member. The mesh cylinder is sleeved on the bottom of the column. A torsion spring is provided on the outer side wall of the column. One end of the torsion spring is connected to the mesh cylinder, and the other end of the torsion spring is connected to the outer side wall of the column. A microswitch is installed on the outer side wall of the mesh cylinder, and the microswitch is located between the outer side wall of the mesh cylinder and the inner wall of the cylinder body. The microswitch is electrically connected to the cylinder.

[0007] The present invention is further configured as: The bottom wall of the oil collecting member is provided with an inclined portion, and the inclined portion extends towards one end of the oil collecting member away from the sliding member and forms an opening.

[0008] The present invention is further configured such that: an elastic member is disposed inside the oil collecting member, one end of the elastic member is connected to the bottom wall of the oil collecting member, the other end of the elastic member is connected to a cleaning member, and the cleaning member is slidably connected inside the oil collecting member.

[0009] The present invention is further configured such that: a limiting groove is formed on the outer sidewall of the rotating rod, a limiting member is fixedly connected to the inner wall of the sliding member, and one side of the limiting member is inserted into the limiting groove.

[0010] The present invention is further configured such that: a driving motor is installed on the top of the cover body, the output end of the driving motor penetrates through the top of the cover body and is connected to the top of the rotating rod, an oil collecting groove is formed on the inner wall of the cylinder body, and the oil discharge hole is located inside the oil collecting groove.

[0011] The present invention is further configured such that: an oil collecting tank is sleeved on the outer sidewall of the cylinder body, and the oil collecting tank is communicated with a plurality of oil discharge holes.

The drainage member is located outside the cylinder body, and both ends of the drainage member are respectively communicated with the upper cavity and the lower cavity.

[0013] The present invention is further configured such that: a solenoid valve is installed on the outer sidewall of the drainage member, a control switch is installed at the bottom of the mesh cylinder, and the control switch is electrically connected to the solenoid valve.

[0014] The present invention is further configured such that: a spring is installed on the bottom wall of the cylinder body. The top of the spring abuts against the bottom of the partition plate, and the spring is sleeved on the outer sidewall of the rotating rod.

[0015] The advantages of the present invention are as follows: by providing an oil collecting member, the oil collecting member floats on the surface of the sewage and rotates synchronously with the rotating rod, so as to clean the oil on the surface of the sewage.

[0025] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0026] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present invention.

[0027] Please refer to Figures 1-7 , the present invention provides the following technical solutions:

[0028] A short-time forced oil-water separation treatment device with continuous inlet and outlet, comprising a cylinder 1 and a cover body 2. The cover body 2 is installed on the top of the cylinder 1, and a separation assembly 3 and a cleaning assembly 4 are installed inside the cylinder 1;

[0029] The separation component 3 includes a rotating rod 33. The rotating rod 33 is located inside the cylinder body 1. A driving motor 31 is installed on the top of the cover body 2. The output end of the driving motor 31 penetrates through the top of the cover body 2 and is connected to the top of the rotating rod 33. The driving motor 31 is used to drive the rotating rod 33 to rotate inside the cylinder body 1. A sliding member 34 and a pushing member 39 are slidably connected to the outer side wall of the rotating rod 33. The pushing member 39 is located above the sliding member 34. The inside of the pushing member 39 is hollow and filled with salt. Its side wall is evenly installed with filters. Two oil collecting members 35 are fixedly connected to the outer side wall of the sliding member 34. The rotating rod 33 is used to guide the sliding member 34 and the pushing member 39. That is, when sewage is injected into the cylinder body 1, the oil collecting members 35 move upward under the buoyancy of the sewage. The sliding member 34 and the pushing member 39 can slide on the outer side wall of the rotating rod 33. A limiting groove 38 is formed on the outer side wall of the rotating rod 33. A limiting member 391 is fixedly connected to the inner wall of the sliding member 34. One side of the limiting member 391 is inserted into the limiting groove 38. When the sliding member 34 slides on the outer side wall of the rotating rod 33, the sliding member 34 drives the limiting member 391 to slide inside the limiting groove 38, so as to play a guiding role for the sliding member 34. At the same time, because the limiting member 391 is inserted into the limiting groove 38, when the rotating rod 33 rotates, the sliding member 34 and the oil collecting members 35 will rotate synchronously with the rotating rod 33, and it does not affect the up and down sliding movement of the sliding member 34. A cylinder 395 is installed on the top of the pushing member 39. The oil collecting members 35 drive the sliding member 34 and the pushing member 39 to move upward. When the pushing member 39 drives the cylinder 395 to contact the cover body 2, the sliding member 34 and the pushing member 39 cannot move upward continuously. At this time, the piston rod of the cylinder 395 can push the pushing member 39 and the sliding member 34 to move downward and immerse in the sewage. The oil collecting members 35 can extend into the sewage and rotate, so that the sewage can be stirred in the cylinder body 1, and the sewage is in a vortex state. And the water body enters the inside of the pushing member 39 through the filter, so that the salt inside the pushing member 39 melts, increasing the density of the water body and accelerating the oil-water separation;

[0030] One side of the oil collecting member 35 is an inclined surface, and a number of oil inlet holes 393 are provided on the inclined surface. When the oil collecting member 35 rotates, it scrapes the oil on the surface of the sewage, and the scraped oil enters the interior of the oil collecting member 35 through the oil inlet holes 393 on the inclined surface and accumulates. The bottom wall of the oil collecting member 35 is provided with an inclined portion, and the inclined portion extends towards one end of the oil collecting member 35 away from the sliding member 34 and forms an opening. When the oil enters the interior of the oil collecting member 35, the oil will flow towards the opening along the inclined direction of the inclined portion. An oil collecting groove 36 is provided on the inner wall of the cylinder body 1, and a number of oil discharge holes 37 are provided on the inner side wall of the cylinder body 1. The oil discharge holes 37 are located inside the oil collecting groove 36. When the oil flows to the opening, it will directly enter the oil collecting groove 36, and the oil in the oil collecting groove 36 will flow out through the oil discharge holes 37. At the same time, the oil collecting groove 36 is used to block the oil to avoid the situation where the oil that has not flowed out through the oil discharge holes 37 flows back, so as to continuously clean the oil in the sewage. A fuel tank 32 is sleeved on the outer side wall of the cylinder body 1, and the fuel tank 32 is communicated with a number of oil discharge holes 37. The fuel tank 32 is used to collect the oil flowing out of the oil discharge holes 37;

[0031] An elastic member 392 is provided inside the oil collecting member 35. One end of the elastic member 392 is connected to the bottom wall of the oil collecting member 35, and the other end of the elastic member 392 is connected to a cleaning member 394. The cleaning member 394 is slidably connected inside the oil collecting member 35. When the position of the oil collecting member 35 on the outer wall of the rotating rod 33 is relatively high, the elastic member 392 will contact the bottom of the cover body 2 and be squeezed. When the elastic member 392 deforms, it will push the cleaning member 394 to slide inside the oil collecting member 35, so as to scrape the oil inside the oil collecting member 35;

[0032] The cleaning assembly 4 includes a column 44 and a mesh cylinder 45. The column 44 is movably connected to the bottom of the oil collecting member 35. The mesh cylinder 45 is sleeved on the bottom of the column 44. A flexible storage box is installed inside the mesh cylinder 45, and a cleaning liquid is contained in the flexible storage box. A one-way opening is provided outside the storage box, that is, the cleaning liquid can only be discharged from the storage box, and the external sewage cannot enter the storage box. When the pushing member 39 pushes the sliding member 34 and the oil collecting member 35 to move downward, the oil collecting member 35 will drive the column 44 to move downward and extend into the mesh cylinder 45. The flexible storage box inside the mesh cylinder 45 is squeezed, and the cleaning liquid is squeezed out. As the oil collecting member 35 rotates continuously, the column 44 will drive the mesh cylinder 45 to slide on the inner wall of the cylinder body 1, so as to wipe and clean the oil stains adhered to the inner wall of the cylinder body 1;

[0033] The cleaning assembly 4 further includes a drainage member 41 and a partition 42. The partition 42 is located inside the cylinder body 1 and sleeved on the outer side wall of the rotating rod 33. The partition 42 divides the cylinder body 1 into an upper cavity and a lower cavity;

[0034] An electromagnetic valve 49 is installed on the outer side wall of the drain part 41, and a control switch 48 is installed at the bottom of the mesh cylinder 45. The control switch 48 is electrically connected to the electromagnetic valve 49. The electromagnetic valve 49 is used to control the closing and penetration of the drain part 41, and the control switch 48 is used to control the opening and closing of the electromagnetic valve 49;

[0035] A spring 43 is installed on the bottom wall of the cylinder body 1. The top of the spring 43 abuts against the bottom of the partition plate 42, and the spring 43 is sleeved on the outer side wall of the rotating rod 33. The partition plate 42 will move up or down according to the amount of water in the cylinder body 1. The spring 43 is used to support the partition plate 42, and when there is less sewage in the cylinder body 1, the spring 43 can reset the partition plate 42. The drain part 41 is located outside the cylinder body 1, and both ends of the drain part 41 are respectively communicated with the upper cavity and the lower cavity. The drain part 41 is used to drain the water in the upper cavity into the lower cavity for collection. Embodiment

[0036] Specifically, a water injection port is arranged at the top of the cover body 2. The staff continuously discharges sewage into the upper cavity of the cylinder body 1 through the water injection port. As the sewage in the cylinder body 1 continuously increases, the partition plate 42 slides down under the influence of gravity inside the cylinder body 1 and compresses the spring 43. At this time, the oil collecting part 35 and the sliding part 34 float on the water surface of the sewage and will slide up on the outer side wall of the rotating rod 33 following the rising height of the sewage water surface. The staff presses the switch to control the start of the driving motor 31, and the output end of the driving motor 31 drives the rotating rod 33 to rotate. When the sliding part 34 slides up on the outer side wall of the rotating rod 33, the sliding part 34 and the oil collecting part 35 rotate synchronously with the rotating rod 33;

[0037] When there is more water in the sewage, since the density of water is greater than that of oil, a small amount of oil will float on the water surface to form a layer. When the sliding part 34 and the oil collecting part 35 rotate on the water surface of the sewage, the oil on the upper layer can be scraped off. The oil enters the inside of the oil collecting part 35 through the oil inlet hole 393, flows along the inclination direction of the inclined part inside the oil collecting part 35, and is discharged through the oil collecting groove 36 and the oil discharge hole 37. The oil body is collected by the oil collecting tank 32, and the water in the lower layer flows through the drain part 41 into the lower cavity to accumulate, thereby realizing oil-water separation;

[0038] Under normal conditions, the oil collecting part 35 will drive the upright post 44 and the mesh cylinder 45 to displace, and the side wall of the mesh cylinder 45 abuts against the inner wall of the cylinder body 1. At this time, since there is no oil stain on the inner wall of the cylinder body 1 corresponding to the mesh cylinder 45, the mesh cylinder 45 will frictionally slide on the inner wall of the cylinder body 1. Due to the relatively large frictional force, the mesh cylinder 45 rotates a certain angle during the sliding process. The microswitch 47 moves away from the inner wall of the cylinder body 1 through the rotation of the mesh cylinder 45, and the torsion spring 46 deforms;

[0039] When there is a large amount of oil in the sewage, the height of the oil layer in the sewage increases, while the water layer decreases relatively. As a result, the contact area between the oil layer and the inner wall of the cylinder 1 increases, and the inner wall of the cylinder 1 corresponding to the mesh cylinder 45 is contaminated with oil stains, so the friction force decreases, and the mesh cylinder 45 cannot relatively squeeze and twist the torsion spring 46 with the inner wall of the cylinder 1. The elastic force of the torsion spring 46 drives the mesh cylinder 45 to reset, and the microswitch 47 on the outer side wall of the mesh cylinder 45 is triggered. The microswitch 47 controls the piston rod of the cylinder 395 to extend. Since the top of the cylinder 395 is not connected to the cover body 2, and the oil collecting part 35 and the sliding part 34 float on the water surface, when the piston rod of the cylinder 395 extends, the outer shell of the cylinder 395 will first move up and fit on the cover body 2 to form a blocking support. Secondly, the outer shell of the cylinder 395 abuts against the cover body 2, and the piston rod continues to extend. The piston rod of the cylinder 395 pushes the pushing part 39 and the sliding part 34 to slide down on the outer side wall of the rotating rod 33, causing the pushing part 39, the sliding part 34 and the oil collecting part 35 to enter the sewage. At the same time, the oil collecting part 35 and the sliding part 34 continue to rotate, so as to stir the sewage. The pushing part 39 is filled with salt. When the pushing part 39 is immersed in water, the water body enters the pushing part 39 through the filter screen, causing the salt in the pushing part 39 to melt, increasing the salinity of the water body and increasing the density of the water body, thereby accelerating the stratification efficiency of the water body and the oil;

[0040] The sewage forms a vortex state through the stirring of the oil collecting part 35 and the sliding part 34. The edge position will be higher than the central position. Since the oil accumulates above the water, when the sewage forms a vortex, the upper layer of oil will be lifted in height through the vortex state, so that the upper layer of oil is forced to pass through the oil collecting groove 36 and the oil discharge hole 37 and discharged into the interior of the oil collecting tank 32, thereby accelerating the oil-water separation efficiency;

[0041] When the oil collecting part 35 moves down into the sewage, the oil collecting part 35 will drive the column 44 to move down and squeeze the mesh cylinder 45, and the control switch 48 at the bottom of the mesh cylinder 45 is triggered. The control switch 48 controls the solenoid valve 49 to close, and the solenoid valve 49 closes the drainage part 41, so that the sewage no longer enters the lower cavity, preventing part of the oil from entering the lower cavity during the sewage stirring and causing secondary pollution of the water body. The cleaning liquid in the mesh cylinder 45 is squeezed out and cleans the inner wall of the cylinder 1. Since there is a large amount of oil in the sewage, after the mesh cylinder 45 wipes once, the oil adheres to the inner wall of the cylinder 1 again. As the oil in the sewage gradually decreases, the position of the inner wall of the cylinder 1 corresponding to the mesh cylinder 45 gradually changes from oil to water, and the inner wall of the cylinder 1 is cleaned by the continuous rotation of the mesh cylinder 45.
