Description

Technical Field

[0001] The invention relates to the technical field of water treatment applications, in particular to an oil remover with flocculation and sedimentation functions. Background Art

[0002] Chemical degreaser is a degreasing device for treating wastewater with low oil concentration. By adding chemical agents, after mixing reaction, the oil and suspended solids in the water are separated by coagulation and flocculation, so as to achieve the purpose of purifying water quality. Chemical degreaser is widely used in the treatment of oily wastewater in steel enterprises, petrochemical industry, oil fields, shipbuilding and shipyard, tanker cleaning, mining, mechanical processing and other industries. The existing publication number is CN104386779B, which is a high-efficiency chemical degreaser. It includes a support and a cylinder. The cylinder includes a conical mud collecting hopper at the bottom and a reaction chamber, an inclined tube filling area, and a clean water chamber arranged above it in sequence. The inclined tube filling area divides the reaction chamber and the clean water chamber into two independent cavities. A mixing chamber is provided in the cylinder below the inclined tube filling area. The bottom of the mixing chamber is connected to the water inlet pipe, and a hollow ball stirring area is provided at the top outlet of the mixing chamber. The incoming water rises from the mixing chamber to the hollow ball stirring area and overflows into the reaction chamber. After sufficient reaction in the reaction chamber, the clean water overflows from the inclined tube filling area into the clean water chamber and then flows out through the upper water outlet pipe at the top of the cylinder. The present invention occupies a small area, operates stably, and saves energy and reduces consumption. In general, the above patents or prior art first put it into sewage and then stir it. This method results in many local dead corners in the stirring area. During the overall stirring, the materials at the edge or bottom of the stirring area are not fully mixed. Summary of the Invention

[0003] The object of the present invention is to provide an oil remover with flocculation and sedimentation functions to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions: Provided is an oil remover with flocculation and sedimentation functions, comprising an operating table, a plurality of oil removal tank assemblies connected to the operating table, a drive assembly connected to the upper end of the oil removal tank assembly, and an oil removal mechanism connected inside the oil removal tank assembly; The oil removal mechanism includes: A stirring assembly is provided in the oil removal tank assembly, and a quantitative feeding assembly is provided above the stirring assembly.

[0005] Furthermore, the oil removal tank assembly includes: An oil flocculant storage bin is provided with a stirring bin below the oil flocculant storage bin, a gravity sedimentation bin is provided below the stirring bin, a filter is provided below the gravity sedimentation bin, a water outlet is provided below the filter, an oil flocculant input port is provided on the outside of the oil flocculant storage bin, and a sewage inlet is provided on the outside of the stirring bin.

[0006] Furthermore, the driving assembly includes: The motor is fixedly connected to the upper end of the oil flocculant storage bin, the output end of the motor is fixedly connected to one end of the drive shaft, and the drive shaft is rotatably connected to the upper end of the oil flocculant storage bin.

[0007] Furthermore, the quantitative feeding component includes: A star-shaped turntable, the star-shaped turntable is fixedly connected to the drive shaft, a plurality of push rods are slidably connected to the star-shaped turntable, the plurality of push rods are annularly arranged on the star-shaped turntable, a spring is sleeved on the push rod, one end of the spring is fixedly connected to the lower end of the star-shaped turntable, and the other end of the spring is fixedly connected to the push rod, the lower end of the push rod is fixedly connected to the conical plug, and the upper end of the push rod is fixedly connected to the push ball; and A top block is fixedly connected to the top of the oil flocculant storage bin.

[0008] Furthermore, the stirring assembly includes: The isolation plate 1 is fixedly connected to the top of the stirring bin, the isolation plate 1 is provided with a plurality of oil flocculant outlets, a plurality of the conical plugs slide in the oil flocculant outlets, and the isolation plate 1 is fixedly connected to the drive shaft.

[0009] Furthermore, the upper end of the isolation plate 1 is rotatably connected to a plurality of gears 1 and 2, and the gear 1 is engaged with the gear 2. The lower end of the isolation plate 1 is provided with a plurality of stirring rods, and the stirring rods are fixedly connected to the gear 1.

[0010] Furthermore, a gear ring is fixedly connected above the mixing bin, the gear ring is engaged with gear 2, isolation plates 2 are respectively provided on both sides of the mixing rod, the isolation plates 2 are fixedly connected to the lower end of isolation plate 1, and a mixing outlet is opened at the bottom of the mixing bin.

[0011] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects: 1. The sewage is allowed to enter the area between the next two adjacent isolation plates for stirring. Several isolation plates are provided to divide the stirring area into several equal parts. Compared with the overall stirring, this stirring method reduces the local dead angles in the stirring area. During the overall stirring, the materials at the edge or bottom of the stirring area are mixed more fully. The stirring blades of the stirring rod are fixedly mounted with prism-shaped protrusions. During stirring, as the stirring rod rotates, the mixed liquid hits the inclined surface of the prism-shaped protrusion. After hitting the lower inclined surface, there is a downward force, and after hitting the upper inclined surface, there is an upward thrust, thereby increasing the longitudinal fluidity of the liquid, which is more conducive to mixing and full reaction.

[0012] 2. When the driving shaft rotates, it drives the isolation plate to rotate together, and the conical plug slides downward in the oil flocculant outlet. When the end with a larger diameter on the conical plug leaves the oil flocculant outlet, the oil flocculant stored in the oil flocculant storage bin enters the mixing bin through the oil flocculant outlet under the action of gravity and mixes with the sewage until the top ball and the top block are completely separated. The spring resets, the conical plug moves up, and the release of the oil flocculant stops. When the motor speed is constant, the contact time between the top ball and the top block is fixed, so the time of releasing the oil flocculant is constant, and thus the amount of oil flocculant released is also constant, resulting in small dosing error and low cost.

[0016] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0017] Reference Figure 1-4 As shown, a deoiler with flocculation and sedimentation function includes an operating table 1, a plurality of deoiling tank assemblies 2 are connected to the operating table 1, a driving assembly 3 is connected to the upper end of the deoiling tank assembly 2, and an oil removal mechanism 4 is connected inside the deoiling tank assembly 2; The oil removal mechanism 4 includes: A stirring assembly 41 is provided in the oil removal tank assembly 2 , and a quantitative feeding assembly 42 is provided above the stirring assembly 41 .

[0018] The sewage and the oil flocculant are transported into the oil removal tank assembly 2, and the driving assembly 3 is started, so that the driving assembly 3 drives the quantitative feeding assembly 42 and the stirring assembly 41 to rotate together, and the mixture of the sewage and the oil flocculant is stirred, so that the oil flocculant can fully react with the oil and suspended matter in the sewage, causing them to coagulate, flocculate, and then settle and separate.

[0019] The oil removal tank assembly 2 includes: An oil flocculant storage bin 21 is provided with a stirring bin 22 below the oil flocculant storage bin 21, a gravity sedimentation bin 23 is provided below the stirring bin 22, a filter screen 24 is provided below the gravity sedimentation bin 23, a water outlet 25 is provided below the filter screen 24, an oil flocculant input port 26 is provided on the outside of the oil flocculant storage bin 21, and a sewage inlet 27 is provided on the outside of the stirring bin 22.

[0020] The oil flocculant is stored in the oil flocculant storage bin 21 through the oil flocculant inlet 26, and the sewage enters the mixing bin 22 through the sewage inlet 27. The driving component 3 allows the oil flocculant in the oil flocculant storage bin 21 to enter the mixing bin 22 in a quantitative manner under the action of gravity to be mixed and stirred with the sewage, and then passes through the filter 24 under the action of gravity, so that the oil and suspended matter are coagulated, and the flocculated products are separated from the water.

[0021] Reference Figure 5 As shown, the driving component 3 includes: The motor 31 is fixedly connected to the upper end of the oil flocculant storage bin 21 , and the output end of the motor 31 is fixedly connected to one end of a drive shaft 32 , and the drive shaft 32 is rotatably connected to the upper end of the oil flocculant storage bin 21 .

[0022] When the motor 31 rotates, it drives the drive shaft 32 fixedly connected thereto to rotate together.

[0023] Reference Figure 10 As shown, the quantitative feeding component 42 includes: A star-shaped turntable 421, the star-shaped turntable 421 is fixedly connected to the drive shaft 32, and a plurality of push rods 422 are slidably connected to the star-shaped turntable 421. The plurality of push rods 422 are annularly arranged on the star-shaped turntable 421, and a spring 423 is sleeved on the push rod 422. One end of the spring 423 is fixedly connected to the lower end of the star-shaped turntable 421, and the other end of the spring 423 is fixedly connected to the push rod 422. The lower end of the push rod 422 is fixedly connected to a tapered plug 424, and the upper end of the push rod 422 is fixedly connected to a push ball 425; and A top block 426 is fixedly connected to the top of the oil flocculant storage bin 21 .

[0024] By rotating the drive shaft 32, the star-shaped turntable 421 is driven to rotate together, and then the top rod 422, the top ball 425, the conical plug 424 and the spring 423 are driven to rotate together. When the top ball 425 rotates to the position of the top block 426, the top ball 425 pushes the top rod 422 to slide downward, the spring 423 is compressed, and the conical plug 424 moves downward together.

[0025] Reference Figure 6-9 As shown, the stirring assembly 41 includes: An isolation plate 411 is fixedly connected to the top of the mixing chamber 22 . A plurality of oil flocculant outlets 412 are provided on the isolation plate 411 . A plurality of conical plugs 424 slide in the oil flocculant outlets 412 . The isolation plate 411 is fixedly connected to the drive shaft 32 .

[0026] When the drive shaft 32 rotates, it drives the isolation plate 411 to rotate together, and the conical plug 424 slides downward in the oil flocculant outlet 412. When the end with the larger diameter of the conical plug 424 leaves the oil flocculant outlet 412, the oil flocculant stored in the oil flocculant storage bin 21 enters the mixing bin 22 through the oil flocculant outlet 412 under the action of gravity and mixes with the sewage until the top ball 425 is completely separated from the top block 426, the spring 423 is reset, the conical plug 424 moves up, and the release of the oil flocculant stops. When the speed of the motor 31 is constant, the contact time between the top ball 425 and the top block 426 is fixed, so the time for releasing the oil flocculant is constant, and thus the amount of oil flocculant released is also constant.

[0027] The upper end of the isolation plate 1 411 is rotatably connected to a plurality of gears 1 413 and gear 2 414 , and the gear 1 413 is engaged with the gear 2 414 . The lower end of the isolation plate 1 411 is provided with a plurality of stirring rods 415 , and the stirring rods 415 are fixedly connected to the gear 1 413 .

[0028] The upper end of the isolation plate 411 is rotatably connected to a plurality of gears 1 413 and gear 2 414. The lower end of the isolation plate 411 is provided with a plurality of stirring rods 415. The stirring rods 415 are fixedly connected to the gear 1 413. The drive shaft 32 drives the isolation plate 411 to rotate. The stirring blades of the stirring rods 415 are fixedly mounted with prism-shaped protrusions. When stirring, as the stirring rods 415 rotate, the mixed liquid hits the inclined surface of the prism-shaped protrusion. After hitting the lower inclined surface, there is a downward force, and after hitting the upper inclined surface, there is an upward thrust, thereby increasing the longitudinal fluidity of the liquid, which is more conducive to mixing and sufficient reaction.

[0029] A gear ring 416 is fixedly connected to the top of the mixing chamber 22, and the gear ring 416 is engaged with the gear 2 414. Isolation plates 2 417 are respectively provided on both sides of the mixing rod 415, and the isolation plates 2 417 are fixedly connected to the lower end of the isolation plate 1 411. A mixing outlet 418 is opened at the bottom of the mixing chamber 22.

[0030] When the isolation plate 1 411 rotates, when the area between two adjacent isolation plates 2 417 rotates to the sewage inlet 27 position, the sewage enters this area. When this area leaves the sewage inlet 27 position, the sewage enters the area between the next two adjacent isolation plates 2 417. Due to the engagement of the gear 1 413 and the gear ring 416, the gear 2 414 rotates, thereby driving the stirring rod 415 to rotate, so that the sewage entering between the two adjacent isolation plates 2 417 is fully mixed and reacted with the oil flocculant. When the area between the two adjacent isolation plates 2 417 rotates to the mixing outlet 418 position, it falls onto the filter net under the action of gravity for filtration.
