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 recycling, which can not only reduce production costs, but also help save resources and protect the environment.

[0003] The patent with the announcement number CN219384961U discloses an ammonia nitrogen wastewater treatment device that is convenient for dosing, including: a sedimentation tank for treating ammonia nitrogen wastewater, and a filtering mechanism for filtering sediment. The patent realizes an ammonia nitrogen wastewater treatment device that is convenient for dosing through the cooperation of the sedimentation tank, the filtering mechanism, the dosing mechanism, the moving mechanism, the liquid inlet pipe, the feed port and the discharge pipe. The lifting hydraulic rod pushes the top plate to rise, and the dosing bin is driven to rise by the support rod. When the dosing bin reaches the top, the translation hydraulic rod contracts and drives the mounting plate to move right. At this time, the rotating wheel is stuck in the limit track to support the dosing bin. The baffle moves to the left under the push of the feed port, and the discharge port leaks out, so that the reaction drug in the dosing bin is put into the sedimentation bin to complete the dosing process. There is no need for manual dosing, and at the same time, it is avoided that the operator climbs up and down, which ensures the personal safety of the operator and improves the practicality.

[0004] However, the above technical solution still has the following deficiencies in practical application: 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 a synergistic effect, 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 each time is the same, 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 a 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

[0022] The technical solution of the present invention will be described clearly and completely below 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a carbon fiber precursor oil wastewater treatment device with a multi-stage filtering function, comprising a base 1, a reaction pool 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 pool 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 pool 2, a coarse filter screen 47 and a fine filter screen 48 are arranged in a transverse arrangement in the inner cavity of the filter box 5, and multiple types of dosing mechanisms are also arranged on the base 1; The various dosing mechanisms include a displacement plate 10 slidably connected to the upper end surface of the base 1, a slide bar 9 is fixedly connected to both ends of the upper side of the displacement plate 10, a transverse plate 11 is slidably connected to the slide bar 9, two slide bars 13 are slidably connected to the transverse plate 11, a mounting plate 14 is fixedly connected to the lower end of the slide bar 13, a support ring 18 is fixedly connected to one end of the lower side of the mounting plate 14, a gear ring 19 is sleeved on the outer ring of the support ring 18 and rotatably connected, 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, 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; A drug control component is also provided on the support ring 18; The drug control assembly 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 feed cavity.

[0024] 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 .

[0026] 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; thereby, the carbon fiber precursor oil wastewater can be effectively purified through multi-stage filtration to meet the reuse standard.

[0027] In this embodiment, Figure 1 , Figure 2 , Figure 4 , Fig.11As 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 8 is threadedly connected to one end of the transverse plate 11, and both ends of the threaded rod 8 are rotatably set on the displacement plate 10, a motor 7 is fixedly connected to one side of the upper end of the displacement plate 10, and the output end of the motor 7 is fixedly connected to one end of the threaded rod 8, a cylinder 12 is fixedly connected to one side of the upper end surface of the transverse plate 11, and the piston end of the cylinder 12 is fixedly connected to one side of the upper end of the mounting plate 14.

[0028] A connecting rod 23 is slidably connected to one side of the mounting plate 14, and a displacement ring 24 is fixedly connected to one end of the lower side of the connecting rod 23. A plurality of connecting rods 25 are arranged on the outer circle of the displacement ring 24 for rotation. 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.

[0029] Specifically, in the prior art, the wastewater treatment drug is first placed in the drug dosing bin, and then the drug is added to the reaction tank 2 by the drug dosing bin to react 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 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 each time is the same, which is difficult to meet different drug dosing requirements. In addition, the drug dosing direction and range are too single. In some cases, the concentration of pollutants in only a corner or a specific area of ​​the reaction tank 2 is high. 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. Therefore, in order to solve the above problems, when using this embodiment, different types of drugs are added to the cartridge 16, and different solenoid valves are opened according to the types of pollutants contained in the wastewater, so that the drugs in different cartridges 16 are discharged through the hose 31 and the drug outlet 30, and 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, which is beneficial to improving the treatment effect of the wastewater; In addition, when the drug is discharged into the wastewater through the drug outlet 30, the drug will first enter the conical feeding cavity formed by the cavity plate 27 and the rubber pad 28. Therefore, when the pollutant concentration in only a corner or a specific area of ​​the reaction tank 2 is high, 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 rise and fall, so as to adjust the position of the conical feeding cavity in the X, Y, and Z axis directions, so that the lower end of the conical feeding 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 25 can be driven to rotate, so that 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 area. At this time, the drug is discharged from the cartridge 16, and the drug will only be concentrated in the polluted area, thereby realizing accurate drug addition, improving treatment efficiency, and avoiding drug waste.

[0030] In this embodiment, Figure 2 , Figure 3-Figure 5 , Figure 7 , Fig. 9 , Fig.10 As 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.

[0031] 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 .

[0032] The mounting plate 14 is also provided with an opening-adaptive, spill-proof and anti-blocking integrated component; The opening adaptive throwing anti-blocking integrated component includes a cylinder 2 15 fixedly connected to one end of the upper side of the mounting plate 14, the piston end of the cylinder 2 15 is fixedly connected to the support plate 32, and a rotating shaft 34 is rotatably arranged in the middle of the lower end surface of the support plate 32, and 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.

[0033] A motor 7 33 is fixedly connected to one side of the upper end surface of the support plate 32, and the output end of the motor 7 33 is fixedly connected to the upper end of the rotating shaft 34. A threaded rod 2 40 is threadedly connected to one side of the telescopic block 41, and one end of the threaded rod 2 40 is rotatably set on the groove block 36, and one end of the threaded rod 2 40 is fixedly connected to a bevel gear 2 39. A motor 4 37 is fixedly connected to one side of the inner cavity at the bottom of the rotating shaft 34, and a bevel gear 1 38 is fixedly connected to the output end of the motor 4 37, and the bevel gear 1 38 and the bevel gear 2 39 are meshed with each other.

[0034] A cover body 17 is rotatably provided at the lower end of one side material cavity plate 27 , and a motor 35 is fixedly connected to one side of the lower end of one side material cavity plate 27 , and an output end of the motor 35 is fixedly connected to one end of the cover body 17 .

[0035] 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 wastewater, it is difficult to quickly achieve synergistic effects. In addition, in some cases, it is necessary to uniformly add drugs to wastewater, and when the drugs are only discharged from the conical feeding cavity, although targeted drug addition can be achieved, the drugs are difficult to be evenly distributed in various positions in the wastewater, thereby affecting the subsequent treatment effect. Therefore, in order to solve the above problems, when the present embodiment is used, when it is necessary to make different kinds of medicines achieve synergistic effects, 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 feeding cavity is blocked, and then the solenoid valve on the corresponding medicine cartridge 16 is opened to make different kinds of medicines fall into the conical feeding cavity uniformly. At the same time, the motor 20 drives the gear 21 to rotate, so that the gear ring 19 rotates, and the medicine cartridge 16 performs a circular motion. At the same time, the cylinder 4 29 is used to drive the medicine outlet 30 to move laterally, so that the medicine can be evenly added to various positions in the conical feeding cavity under the action of the rotation of the medicine outlet 30 and the lateral displacement composite motion, and the medicine will accumulate on the cover 17, so that different kinds of medicines are evenly mixed, and then the cover 17 is driven away from the material. At the bottom of the cavity plate 27, the mixed medicine falls accurately into the pollutant area, so that before different types of medicines are added to the wastewater, the medicines can be evenly mixed 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 feeding cavity, 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 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 fits 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 medicine, so that the mixed medicine can be effectively prevented from being blocked when it is discharged from the bottom of the conical feeding cavity, thereby ensuring the smooth addition of medicine. Furthermore, when it is necessary to evenly distribute the medicine in the reaction pool 2, the cylinder 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 contact the rotating groove block 36 and the telescopic block 41, and both can scatter the falling medicine to evenly distribute the medicine in the reaction pool 2, thereby avoiding the situation that the medicine is only discharged from the conical discharge chamber, resulting in a limited discharge range of the medicine and it is difficult to evenly distribute it in various positions in the wastewater, thereby further improving the wastewater treatment effect.

[0036] 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 the 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 the 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, through the multi-stage filtration method, the carbon fiber precursor oil wastewater can be effectively purified 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, which is beneficial to improving the treatment effect of wastewater;In addition, when the medicine is discharged into the wastewater through the medicine outlet 30, the medicine will first enter the conical feeding cavity formed by the cavity plate 27 and the rubber pad 28. Therefore, 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 17 drives the threaded rod 18 to rotate, and the cylinder 12 drives the mounting plate 14 to rise and fall, so as to adjust the position of the conical feeding cavity in the X, Y, and Z axis directions, so that the lower end of the conical feeding cavity is in the pollutant area, and then according to the area of ​​the pollutant area, the cylinder 3 22 drives 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, the drug is discharged from the cartridge 16, and the drug is only concentrated in the polluted area, thereby achieving accurate drug addition, improving the processing efficiency, and avoiding drug waste. When it is necessary to make different types of drugs achieve synergistic effects, the cover body 17 is first driven to rotate by the motor 35 until the cover body 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 feeding cavity. Meanwhile, the motor 20 drives the gear 21 to rotate, so that the gear ring 19 rotates, and the medicine cartridge 16 performs a circular motion. Meanwhile, the cylinder 4 29 drives the medicine outlet 30 to move laterally. Under the action of the compound motion of the medicine outlet 30 rotating and the lateral displacement, the medicines are uniformly added to various positions in the conical feeding cavity, and the medicines are accumulated on the cover 17, so that different kinds of medicines are uniformly mixed. Then, the cover 17 is driven away from the bottom of the cavity plate 27, and the mixed medicines accurately fall into the pollutant area, so that different kinds of medicines can be uniformly mixed before being added into 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 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 fits 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, and ensuring the smooth addition of drugs.Furthermore, when the drug needs to be evenly distributed in the reaction pool 2, the cylinder 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 feeding chamber. When the drug falls downward, it will contact the rotating groove block 36 and the telescopic block 41, and the two can play a scattering effect on the falling drug, so that the drug is evenly distributed in the reaction pool 2, thereby avoiding the situation that the drug is only discharged from the conical feeding chamber, resulting in a limited discharge range of the drug and it is difficult to evenly distribute it in various positions in the wastewater, and further improving the wastewater treatment effect. ;
