Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, in particular to a carbon fiber precursor oil wastewater treatment device with a multi-stage filtering function. Background Art

[0002] Carbon fiber precursor oil wastewater is wastewater containing oil and other pollutants generated in the production process of carbon fiber precursor. If the carbon fiber precursor oil wastewater is discharged directly without treatment, it will cause serious pollution to the environment. Through wastewater treatment, useful substances in the wastewater, such as oil, can be recovered to achieve resource reuse, which can not only reduce production costs, but also help save resources and protect the environment.

[0003] Patent No. CN219384961U discloses an ammonia nitrogen wastewater treatment device that facilitates drug dosing. The device comprises a sedimentation tank for treating ammonia nitrogen wastewater and a filtration mechanism for filtering the sediment. The patent implements a device that facilitates drug dosing through the interaction of the sedimentation tank, filtration mechanism, dosing mechanism, moving mechanism, liquid inlet pipe, feed port, and discharge pipe. A lifting hydraulic rod pushes the top plate upward, which in turn drives the dosing bin upward via a support rod. When the dosing bin reaches its apex, the translational hydraulic rod retracts, driving the mounting plate to the right. The rotating wheel then engages a limit track, supporting the dosing bin. The baffle, driven by the feed port, moves leftward, allowing the discharge port to leak out, allowing the reactant in the dosing bin to be deposited into the sedimentation bin, completing the dosing process. This eliminates the need for manual dosing and prevents operators from climbing up and down, ensuring operator safety and improving practicality.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] By first placing the wastewater treatment drug into the drug dosing bin, and then using the drug dosing bin to add the drug to the reaction tank, the drug is reacted with the wastewater. Although automatic drug dosing can be achieved in this way, since the wastewater contains many different types of pollutants, such as suspended matter, organic matter, heavy metal ions, oils, etc., these pollutants have different chemical and physical properties and are difficult to be completely removed by a single drug. In addition, some drugs have synergistic effects, that is, they can produce better treatment effects when they work together. In the above technical solution, the drug added to the wastewater by the drug dosing bin is the same each time, which is difficult to meet different drug dosing needs. In addition, the drug dosing direction and range are too single. In some cases, the pollutant concentration is high in only a corner or specific area of ​​the reaction tank. If the drug dosing direction and range are too single, it is difficult to make the drug accurately act on the local polluted area, which not only affects the treatment efficiency but also easily causes drug waste.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Please refer to Figures 1-11The present invention provides a technical solution: a carbon fiber precursor oil wastewater treatment device with a multi-stage filtration function, comprising a base 1, a reaction tank 2 is fixedly connected to one side of the upper end surface of the base 1, a filter box 5 is fixedly connected to one side of the reaction tank 2, a water inlet pipe 6 is connected to one side of the filter box 5, and a water outlet pipe 46 is connected to the other side of the filter box 5, and the water outlet pipe 46 penetrates the inner cavity of the reaction tank 2, a coarse filter screen 47 and a fine filter screen 48 are arranged transversely in the inner cavity of the filter box 5, and multiple types of dosing mechanisms are also provided on the base 1;

[0040] The various dosing mechanisms include a displacement plate 10 slidably connected to the upper end surface of the base 1, with slide bars 9 fixedly connected to both ends of the upper side of the displacement plate 10, which are slidably connected to a transverse plate 11, and two slide bars 2 13 slidably connected to the transverse plate 11, with the lower ends of the slide bars 2 13 fixedly connected to a mounting plate 14, and one end of the lower side of the mounting plate 14 fixedly connected to a support ring 18, and the outer ring of the support ring 18 is sleeved and rotatably connected to a gear ring 19, and a plurality of cartridges 16 are fixedly connected to the upper end surface of the gear ring 19, one side of the cartridge 16 is connected to a hose 31, and one end of the hose 31 is connected to a drug outlet 30, and a solenoid valve is provided at the connection between the cartridge 16 and the hose 31;

[0041] The support ring 18 is also provided with a drug control component;

[0042] The drug control component includes a plurality of stretching rods 26 evenly distributed on the support ring 18 and slidably connected thereto. One end of the stretching rod 26 is fixedly connected to a cavity plate 27, and rubber pads 28 are fixedly connected between adjacent cavity plates 27. The plurality of cavity plates 27 and rubber pads 28 form a conical discharge cavity.

[0043] In this embodiment, Figure 1 、 Figure 6 、 Figure 8 As shown, an activated carbon filter 3 is fixedly connected to one side of the upper end surface of the base 1, one side of the reaction tank 2 is connected to the activated carbon filter 3 through a connecting pipe 49, and one side of the activated carbon filter 3 is connected to a drain pipe 4.

[0044] Stirring blades 45 are rotatably provided on both sides of the inner cavity of the reaction pool 2, and a motor 6 44 is fixedly connected to one side of the outer wall of the reaction pool 2, and the output end of the motor 6 44 is fixedly connected to one end of the stirring blade 45.

[0045] Specifically, the carbon fiber precursor oil wastewater is added to the filter box 5 through the water inlet pipe 6. By setting a coarse filter 47 and a fine filter 48, the coarse filter 47 and the fine filter 48 can effectively intercept large particles of insoluble impurities in the wastewater, such as mud, suspended matter, etc., to prevent them from entering the reaction tank 2, thereby reducing the burden of the subsequent treatment process. When the wastewater enters the reaction tank 2, the reagent is added to the reaction tank 2, and the stirring blade 45 is driven by the motor 6 44 to rotate so that the wastewater and the reagent are fully reacted. After the reaction is completed, the wastewater enters the activated carbon filter 3 through the connecting pipe 49. The activated carbon filter 3 can adsorb soluble organic matter, some inorganic matter and residual heavy metal ions in the wastewater, further improving the treatment effect of the wastewater. Finally, the wastewater can be discharged through the drain pipe 4; thus, through multi-stage filtration, the carbon fiber precursor oil wastewater can be effectively purified and meet the reuse standards.

[0046] In this embodiment, Figure 1 、 Figure 2 、 Figure 4 、 Figure 11 As shown, a threaded rod three 43 is threadedly connected to one side of the bottom of the displacement plate 10, and both ends of the threaded rod three 43 are rotatably set on the base 1. A motor five 42 is fixedly connected to one side of the upper end surface of the base 1, and the output end of the motor five 42 is fixedly connected to one end of the threaded rod three 43. A threaded rod one 8 is threadedly connected to one end of the transverse plate 11, and both ends of the threaded rod one 8 are rotatably set on the displacement plate 10. A motor one 7 is fixedly connected to one side of the upper end of the displacement plate 10, and the output end of the motor one 7 is fixedly connected to one end of the threaded rod one 8. A cylinder one 12 is fixedly connected to one side of the upper end surface of the transverse plate 11, and the piston end of the cylinder one 12 is fixedly connected to one side of the upper end of the mounting plate 14.

[0047] A connecting rod 23 is slidably connected to one side of the mounting plate 14, and a displacement ring 24 is fixedly connected to the lower end of the connecting rod 23. A plurality of connecting rods 25 are provided for rotating the outer ring of the displacement ring 24. One end of the connecting rod 25 is rotatably connected to one end of the stretching rod 26. A cylinder three 22 is fixedly connected to one side of the mounting plate 14, and the piston end of the cylinder three 22 is fixedly connected to one end of the connecting rod 23.

[0048] Specifically, in the prior art, the wastewater treatment drug is first placed in a drug dosing bin, and then the drug is added to the reaction tank 2 by the drug dosing bin to react with the drug. Although automatic drug dosing can be achieved in this way, since the wastewater contains many different types of pollutants, such as suspended matter, organic matter, heavy metal ions, oils, etc., these pollutants have different chemical and physical properties and are difficult to be completely removed by a single drug. In addition, some drugs have a synergistic effect, that is, they can produce better treatment effects when they work together. In the prior art, the drug added to the wastewater by the drug dosing bin is the same each time, which is difficult to meet different drug dosing requirements. In addition, the drug dosing direction and range are too single. In some cases, the pollutant concentration is high only in a corner or a specific area of ​​the reaction tank 2. If the drug dosing direction and range are too single, it is difficult to make the drug act accurately on the local polluted area, which not only affects the treatment efficiency but also easily causes drug waste.

[0049] Therefore, in order to solve the above problems, when using this embodiment, different types of drugs are added to the cartridge 16. According to the type of pollutants contained in the wastewater, different solenoid valves are opened to discharge the drugs in different cartridges 16 through the hose 31 and the drug outlet 30, so that the drugs fall into the wastewater in the reaction tank 2. By opening the solenoid valves corresponding to different cartridges 16, different types of drugs can be added to the wastewater, thereby meeting different drug addition requirements and improving the treatment effect of the wastewater.

[0050] Moreover, since the drug will first enter the conical discharge cavity formed by the cavity plate 27 and the rubber pad 28 when it is discharged into the wastewater through the drug outlet 30, when the pollutant concentration is high in only a corner or a specific area of ​​the reaction tank 2, the motor 5 42 drives the threaded rod 3 43 to rotate, the motor 1 7 drives the threaded rod 1 8 to rotate, and the cylinder 12 drives the mounting plate 14 to move up and down, so as to adjust the position of the conical discharge cavity in the X, Y, and Z axis directions so that the lower end of the conical discharge cavity is in the pollutant area. Then, according to the area of ​​the pollutant area, the cylinder 3 22 drives the connecting rod 23 to move up and down, so that the displacement ring 24 can be moved up and down, and the connecting rod 25 can be rotated. Then, multiple stretching rods 26 slide radially at the same time, and the rubber pad 28 is deformed. Then, the size of the entire conical discharge cavity can be adjusted so that the opening area of ​​the bottom of the conical discharge cavity corresponds to the area of ​​the pollutant area. At this time, when the drug is discharged from the cartridge 16, the drug will only be concentrated in the polluted area, thereby achieving precise dosing, improving treatment efficiency, and avoiding drug waste.

[0051] In this embodiment, Figure 2 、 Figure 3-Figure 5 、 Figure 7 、 Figure 9 、 Figure 10As shown, a cylinder 29 is fixedly connected to one side of the cartridge 16, and a piston end of the cylinder 29 is fixedly connected to the medicine outlet 30.

[0052] A gear 21 is rotatably provided on one side of the support ring 18 , and the gear 21 meshes with the tooth blocks of the outer ring of the gear ring 19 . A motor 20 is fixedly connected to one side of the support ring 18 , and the output end of the motor 20 is fixedly connected to the gear 21 .

[0053] The mounting plate 14 is also provided with an opening-adaptive, spill-proof and anti-blocking integrated component;

[0054] The opening-adaptive throwing and anti-blocking integrated component includes a cylinder 2 15 fixedly connected to one end of the upper side of the mounting plate 14, and the piston end of the cylinder 2 15 is fixedly connected to the support plate 32. A rotating shaft 34 is rotatably provided in the middle of the lower end surface of the support plate 32. Groove blocks 36 are inserted and fixedly connected on both sides of the lower end of the rotating shaft 34, and the groove block 36 is inserted and slidably connected to the telescopic block 41.

[0055] One side of the upper end surface of the support plate 32 is fixedly connected to a motor seven 33, the output end of the motor seven 33 is fixedly connected to the upper end of the rotating shaft 34, one side of the telescopic block 41 is threadedly connected to a threaded rod two 40, one end of the threaded rod two 40 is rotatably set on the groove block 36, one end of the threaded rod two 40 is fixedly connected to a bevel gear two 39, one side of the inner cavity at the bottom of the rotating shaft 34 is fixedly connected to a motor four 37, the output end of the motor four 37 is fixedly connected to a bevel gear one 38, and the bevel gear one 38 and the bevel gear two 39 are meshed with each other.

[0056] The cover body 17 is rotatably provided at the lower end of the material cavity plate 27 on one side, and a motor 35 is fixedly connected to one side of the lower end of the material cavity plate 27 on one side, and the output end of the motor 35 is fixedly connected to one end of the cover body 17.

[0057] Specifically, in the above embodiment, although the type, orientation, and range of drug addition can be controlled, when different types of drugs need to achieve synergistic effects, different types of drugs need to be discharged from the drug outlet 30 at the same time. When different types of drugs are discharged at the same time, each drug is still in an independent state. When added to the wastewater, it is difficult to quickly achieve a synergistic effect. In addition, in some cases, it is necessary to uniformly add the drugs to the wastewater. When the drugs are only discharged from the conical discharge cavity, although targeted drug addition can be achieved, the drugs are difficult to be evenly distributed at various locations in the wastewater, thereby affecting the subsequent treatment effect.

[0058] Therefore, in order to solve the above problems, when the present embodiment is in use, when it is necessary to make different types of medicines achieve a synergistic effect, the motor 35 is first used to drive the cover 17 to rotate until the cover 17 contacts the bottom of the cavity plate 27, so that the bottom of the conical discharge cavity is blocked, and then the solenoid valve on the corresponding cartridge 16 is opened to make different types of medicines fall into the conical discharge cavity uniformly. At the same time, the motor 20 drives the gear 21 to rotate, so that the gear ring 19 rotates, and the cartridge 16 performs a circular motion. At the same time, the cylinder 4 29 is used to drive the medicine outlet 30 to move horizontally, so that under the action of the combined motion of the rotation of the medicine outlet 30 and the lateral displacement, the medicines can be evenly added to various positions in the conical discharge cavity, and the medicines will accumulate on the cover 17, so that different types of medicines are evenly mixed, and then the cover 17 is driven away from the cavity. At the bottom of the cavity plate 27, the mixed medicines fall accurately into the pollutant area, so that different types of medicines can be evenly mixed before being added to the wastewater, and then added to the wastewater, which is conducive to the rapid synergistic effect of the medicines. In addition, according to the size of the conical discharge cavity, the motor 437 can be used to drive the bevel gear 38 to rotate, so that the bevel gear 2 39 and the threaded rod 2 40 can be rotated at the same time, so that the telescopic block 41 slides inside the groove block 36 until the end of the telescopic block 41 is in contact with the inner edge of the lower end of the cavity plate 27. At the same time, the motor 7 33 is used to drive the rotating shaft 34 to rotate, and the rotation of the groove block 36 and the telescopic block 41 is used to stir the mixed medicines, thereby effectively avoiding the blockage when the mixed medicines are discharged from the bottom of the conical discharge cavity, thereby ensuring the smooth progress of the dosing.

[0059] Moreover, when it is necessary to evenly distribute the medicine in the reaction tank 2, the cylinder 2 15 drives the rotating shaft 34 to descend, so that the groove block 36 and the telescopic block 41 are moved out from the bottom of the conical discharge chamber. When the medicine falls downward, it will come into contact with the rotating groove block 36 and the telescopic block 41, and the two can scatter the falling medicine, so that the medicine is evenly distributed in the reaction tank 2, thereby avoiding the situation where the medicine is only discharged from the conical discharge chamber, resulting in a limited discharge range of the medicine and difficulty in evenly distributing it in various positions in the wastewater, thereby further improving the wastewater treatment effect.

[0060] Working principle: The carbon fiber precursor oil wastewater is added to the filter box 5 through the water inlet pipe 6. By setting the coarse filter 47 and the fine filter 48, the coarse filter 47 and the fine filter 48 can effectively intercept large particles of insoluble impurities in the wastewater, such as mud, suspended matter, etc., to prevent them from entering the reaction tank 2, thereby reducing the burden of the subsequent treatment process. When the wastewater enters the reaction tank 2, the reagent is added to the reaction tank 2, and the stirring blade 45 is driven by the motor 6 44 to rotate, so that the wastewater and the reagent are fully reacted. After the reaction is completed, the wastewater is allowed to enter the activated carbon filter 3 through the connecting pipe 49. The activated carbon filter 3 can adsorb soluble organic matter, some inorganic matter and Residual heavy metal ions, etc., further improve the treatment effect of wastewater, and finally, the wastewater can be discharged through the drain pipe 4; thus, the carbon fiber precursor oil wastewater can be effectively purified by multi-stage filtration to meet the reuse standard. When adding medicine, different types of medicines are added to the cartridge 16. According to the type of pollutants contained in the wastewater, different solenoid valves are opened to discharge the medicines in different cartridges 16 through the hose 31 and the medicine outlet 30, so that the medicines fall into the wastewater in the reaction tank 2. By opening the solenoid valves corresponding to different cartridges 16, different types of medicines can be added to the wastewater, thereby meeting different dosing requirements and improving the treatment effect of wastewater;Moreover, since the medicine will first enter the conical discharge cavity formed by the cavity plate 27 and the rubber pad 28 when it is discharged into the wastewater through the medicine outlet 30, when the pollutant concentration is high in only a corner or a specific area of ​​the reaction tank 2, the position of the conical discharge cavity in the X, Y, and Z axis directions is adjusted by driving the threaded rod 3 43 to rotate by the motor 5 42, driving the threaded rod 1 8 to rotate by the motor 1 7, and driving the mounting plate 14 to rise and fall by the cylinder 12, so that the lower end of the conical discharge cavity is in the pollutant area, and then according to the area of ​​the pollutant area, the cylinder 3 22 is used to drive the connecting rod 23 to rise and fall, so that the displacement ring 24 can be moved up and down, and the connecting rod 23 can be driven to rise and fall. When the rod 25 rotates, the multiple stretching rods 26 slide radially at the same time, and the rubber pad 28 is deformed, so that the size of the entire conical feeding cavity can be adjusted so that the opening area of ​​the bottom of the conical feeding cavity corresponds to the area of ​​the pollutant. At this time, when the medicine is discharged from the cartridge 16, the medicine will only be concentrated in the polluted area, thereby achieving accurate dosing, improving processing efficiency, and avoiding waste of medicine. When it is necessary to make different types of medicines achieve synergistic effects, the motor 3 35 is first used to drive the cover 17 to rotate until the cover 17 contacts the bottom of the cavity plate 27, so that the bottom of the conical feeding cavity is blocked, and then the solenoid valve on the corresponding cartridge 16 is opened. Different kinds of medicines are uniformly dropped into the conical discharge cavity. At the same time, the motor 20 drives the gear 21 to rotate, causing the gear ring 19 to rotate, and the medicine cartridge 16 to make a circular motion. At the same time, the cylinder 4 29 is used to drive the medicine outlet 30 to move laterally. Under the action of the compound motion of the rotation and lateral displacement of the medicine outlet 30, the medicines are evenly added to various positions in the conical discharge cavity, and the medicines are accumulated on the cover 17, so that different kinds of medicines are evenly mixed. Then, the cover 17 is driven away from the bottom of the cavity plate 27, and the mixed medicines fall accurately into the pollutant area, so that different kinds of medicines can be evenly mixed before being added to the wastewater. Adding it to the wastewater is conducive to the rapid synergistic effect of the drugs. In addition, according to the size of the conical feeding chamber, the motor 4 37 can be used to drive the bevel gear 1 38 to rotate, so that the bevel gear 2 39 and the threaded rod 2 40 rotate at the same time, so that the telescopic block 41 slides inside the groove block 36 until the end of the telescopic block 41 is in contact with the inner edge of the lower end of the cavity plate 27. At the same time, the motor 7 33 is used to drive the rotating shaft 34 to rotate, and the rotation of the groove block 36 and the telescopic block 41 is used to stir the mixed drugs, thereby effectively avoiding the blockage of the mixed drugs when they are discharged from the bottom of the conical feeding chamber, thereby ensuring the smooth progress of the dosing.Furthermore, when the drug needs to be evenly distributed in the reaction tank 2, the cylinder 2 15 drives the rotating shaft 34 downward, causing the groove block 36 and the telescopic block 41 to move out from the bottom of the conical discharge chamber. As the drug falls downward, it comes into contact with the rotating groove block 36 and the telescopic block 41, which together can scatter the falling drug, making the drug evenly distributed in the reaction tank 2. This avoids the situation where the drug is discharged only from the conical discharge chamber, resulting in a limited discharge range and difficulty in evenly distributing the drug in various locations in the wastewater, further improving the wastewater treatment effect.
