Description

Technical Field

[0001] The present invention relates to the technical field of oil-based needle coke production, and in particular to energy-saving sewage treatment equipment for oil-based needle coke production. Background Art

[0002] The production of oil-based needle coke is a complex and technology-intensive process. The core lies in controlling the formation, growth, fusion, and orderly arrangement of the mesophase, ultimately obtaining coke with a highly anisotropic, fibrous texture. The main process flow includes: raw material pretreatment, coking reaction, coke processing, calcination, screening, and packaging. During the raw material pretreatment process, the raw oil needs to be dehydrated and desalted to remove free water, emulsified water, and salt to ensure the smooth progress of subsequent work. During this process, a large amount of wastewater is generated. This wastewater is a typical highly polluting industrial wastewater with a complex composition and is difficult to treat. The wastewater contains a large amount of sulfur, which is present in the form of organic sulfur. At present, in the process of sewage treatment, the treatment effect of organic sulfide is general, and in the process of sewage treatment, when using a scraper to scrape off impurities floating on the surface, the scraper can only push the impurities and needs to be worked with other tools, which is time-consuming and labor-intensive. In the process of sewage treatment, in order to improve the mixing effect, a stirring device is installed in the sewage, but the stirring direction of the commonly used stirring device is relatively fixed, the stirring effect is general, and the effect of promoting the mixing efficiency of coagulants, flocculants and sewage is general. In the long scraping process, impurities will also stick to the scraper, affecting the normal scraping effect of the scraper. Therefore, an energy-saving sewage treatment device for oil-based needle coke production is provided. Summary of the Invention

[0006] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is designed so that when the interlocking structure is in a state of being more than one, the interlocking structures are to be connected as a group.

[0007] Preferably, a quantitative observation assembly is installed in the box body, and the quantitative observation assembly includes a glass tube, the side wall of the glass tube is fixedly connected to the second rack through the second connecting rod, the outer side of the rotating shaft is fixedly connected to the second gear, the second gear and the second rack are meshed, and the outer side of the rotating shaft is also fixedly connected to a cam, the bottom of the glass tube is slidably connected to a baffle, the upper side of the baffle is fixedly connected to a baffle rod, the side wall of the glass tube is fixedly connected to a cross bar, the lower side of the cross bar is fixedly connected to a third connecting rod, the third connecting rod and the side wall of the box body are slidably connected, and a sixth spring is fixedly connected between the third connecting rod and the box body, the side wall of the baffle rod is fixedly connected to a push plate through a fourth connecting rod, and a seventh spring is fixedly connected between the baffle rod and the cross bar.

[0008] Preferably, the side wall of the box is fixedly connected with a positioning plate, the lower side of the positioning plate is slidably connected with a movable vibration plate via a fifth spring, and the lower side of the movable vibration plate is slidably connected with a contact vibration plate via a fourth spring.

[0009] Preferably, the surfaces of the scraper plate and the baffle are both smooth.

[0010] Preferably, a plurality of supporting legs are fixedly connected to the lower side of the box body, and a shock-absorbing plate is fixedly connected to the lower side of each supporting leg.

[0011] The beneficial effects of the present invention are: 1. First, during the sewage treatment process, the organic sulfide in the sewage can be converted into inorganic sulfide under the action of ultraviolet irradiation lamps and catalysts. Then, under the action of the scraper, the impurities floating on the water surface can be scraped between the baffle and the box, forming a simple removal effect of impurities. It has a simple structure and good practical effect. 2. Secondly, during the sewage treatment process, the scraper plate will be driven to move up and down, causing impurities floating on the water surface to enter between the inclined rod and the scraper plate, thereby collecting the impurities. Then, when the slide plate moves to both sides of the chute, the impurities between the inclined rod and the scraper plate on one side will automatically slide down between the baffle and the box body, further removing the impurities. 3. Then, during the sewage treatment process, the vertical stirring plate and the horizontal stirring plate can be driven to stir the sewage in two different directions, which can greatly accelerate the mixing efficiency of coagulants, flocculants and catalysts with sewage; 4. In addition, when the scraper plate moves downward, the scraper plate drives the pressing plate to move downward through the first connecting rod. The pressing plate and the fixed rod abut against each other, causing the fixed rod and the rotating ring to move towards each other with the fixed round rod as the center. This will cause the sewage to move upward, thereby increasing the possibility of the inclined rod collecting more impurities and further improving the treatment effect of impurities in the sewage. 5. Then, the direction of the motor rotation can be adjusted to drive the glass cylinder upward and remove it from the sewage. At this time, the staff can observe the actual situation of the sewage in the glass cylinder, judge the treatment status of the sewage in the box, and then carry out corresponding treatment; 6. Finally, when the scraper plate is deflected, the scraper plate will move to the lower side of the contact vibration plate. The up and down moving contact vibration plate and the scraper plate will counteract each other, causing the scraper plate to vibrate, reducing the possibility of impurities sticking to the scraper plate.

In this case, it does not belong to the protection point, so it is not described in detail. In this case, the clamping can be completed by using the method of blocks and slots. A plurality of ultraviolet lamps 4 are fixedly connected in the box body 1, two baffles 7 are symmetrically fixedly connected in the box body 1, an air flotation machine 5 is fixedly connected to the bottom of the box body 1, and a The scraping assembly includes a scraping plate 13, a plurality of square tubes 17 are fixedly connected to the upper side of the scraping plate 13, a square rod 16 is slidably connected in each square tube 17, a first spring is fixedly connected between the square rod 16 and the square tube 17, a slide plate 12 is fixedly connected to the upper side of the plurality of square rods 16, a chute 11 is opened on both sides of the box body 1, the slide plate 12 and the chute 11 are slidably connected, a plurality of oblique rods 18 are evenly fixedly connected on both sides of the scraping plate 13, and a power assembly for controlling the movement of the scraping plate 13 is installed in the box body 1; The power assembly includes a motor 6 fixedly mounted on the side wall of the box body 1, the output end of the motor 6 is fixedly connected to a reciprocating screw 8, the outer side of the reciprocating screw 8 is threadedly connected to a moving frame 10, the slide 12 is located in the moving frame 10 and offsets the moving frame 10, the slide 12 deflects, and the offset here refers to not being connected, the box body 1 is rotatably connected to a rotating shaft 9, the rotating shaft 9 passes through the moving frame 10, the rotating shaft 9 is fixedly connected to a plurality of extension plates, the rotating shaft 9 is connected to the reciprocating screw 8 through a first gear 15, and the gear transmission here refers to the rotating shaft 9 and the reciprocating screw 8. The multifilament rods 8 are fixedly connected to the first gears 15, so that the mechanical transmission can be completed by meshing the two first gears 15. The control rods 22 are slidably connected to both sides of the moving frame 10. A second spring 23 is fixedly connected between the control rods 22 and the moving frame 10. The outer side of the control rods 22 is fixedly connected to the control plate 14. The side wall of the control plate 14 is fixedly connected to the cross plate 21. The scraper plate 13 is fixedly connected to the contact rod 20, and the contact rod 20 slides through the slide plate 12 and abuts against the control plate 14. The surfaces of the scraper plate 13 and the baffle 7 are both smooth. First, the flotation machine 5, also known as a dissolved air flotation machine, is a device widely used in the fields of sewage treatment and solid-liquid separation with significant effects. It utilizes the principle of flotation to efficiently separate and treat impurities such as suspended particles, oil, and algae in sewage, thereby purifying the water quality. During operation, a large number of tiny bubbles are generated. These tiny bubbles move upward from the bottom of the housing 1. Impurities in the sewage adhere to the bubbles and float to the surface of the water. Since the sulfides produced by oil-based needle coke during the raw material pretreatment stage are mostly organic sulfides, they adhere to the surface of the tiny bubbles and float to the surface with the tiny bubbles. During the sewage treatment process, the ultraviolet lamp 4 is turned on, and appropriate amounts of catalyst (for example, a persulfate activation catalyst can be used to excite the organic sulfides to produce sulfate ions, and a semiconductor photocatalyst can be used for ultraviolet light-driven free radical generation) are poured into the housing 1 in batches. Under the dual action of the ultraviolet lamp 4 and the catalyst, most of the organic sulfides can be decomposed, significantly reducing the sulfide content in the sewage, ultimately meeting the emission standards. The above are all existing technologies and will not be elaborated on in detail. Secondly, when sewage treatment is required, first close the fixed pipe 3 on the lower side, and introduce the sewage to be treated into the box body 1 through the fixed pipe 3 on the upper side, then close the fixed pipe 3 on the upper side, and pour an appropriate amount of coagulant and flocculant into the sewage to achieve the effect of demulsification and thickening, then cover the box cover 2, start the motor 6, and the motor 6 drives the reciprocating screw 8 to rotate. Since the reciprocating screw 8 and the moving frame 10 are threadedly connected, and under the restriction of the rotating shaft 9, the moving frame 10 will be driven to move back and forth. The slide 12 is located in the moving frame 10, and one end of the slide 12 is against the moving frame 10. Therefore, the moving moving frame 10 will drive the slide 12 to move along the slide 11. The slide 11 is composed of three parts, namely the arc-shaped parts at both ends and In the straight part in the middle, when the slide plate 12 is in the straight part, the moving frame 10 drives the slide plate 12 to move, and the slide plate 12 drives the scraper plate 13 to move through the square rod 16, the square tube 17 and the first spring, and in this process, the reciprocating screw rod 8 also drives the rotating shaft 9 to rotate through the first gear 15. In the process of rotation of the rotating shaft 9, in the initial state, the cross plate 21 does not move, and the second spring 23 does not deform. Then, in the process of rotation of the rotating shaft 9, the rotating shaft 9 drives the extension plate to rotate, and the extension plate and the cross plate 21 are offset to drive the cross plate 21 to move, that is, when the rotating shaft 9 and the extension plate rotate clockwise, the extension plate drives the cross plate 21 on the right to move downward, and drives the cross plate 21 on the left to move upward, and finally guides The control plate 14 on the right side moves downward, the control plate 14 on the left side moves upward, the control plate 14 on the right side and the contact rod 20 are offset, and the contact rod 20 is driven to move downward, and the contact rod 20 drives the scraping plate 13 to move downward relative to the slide plate 12, thereby causing the first spring to deform, and the scraping plate 13 drives the inclined rod 18 to move downward. Since the inclined rod 18 is inclined and the spacing between the inclined rods 18 is small, the multiple inclined rods 18 can squeeze the impurities floating on the sewage to both sides when moving downward. When the inclined rod 18 moves upward, the area formed by the multiple inclined rods 18 and the side wall of the scraping plate 13 is similar to a colander, so that impurities can be collected. Then, when the cross plate 21 and the extension plate are staggered, that is, the rotating extension plate will not be aligned with the cross plate 21. When the scraper plate 13 is in contact with the baffle 7, the scraper plate 13 moves upward relative to the slide 12 under the obstruction of the baffle 7 until the scraper plate 13 and the baffle 7 are disconnected. Then the scraper plate 13 and the baffle 7 continue to move. When the slide 12 moves to the arc part of the chute 11, under the power of the moving frame 10, the slide 12 continues to move along the chute 11. Unlike the straight part, the slide 12 and the scraper plate 13 are deflected as a whole. Figure 4 From the perspective of , when the scraper plate 13 moves to the arc-shaped part on the left, the slide plate 12 and the scraper plate 13 will be deflected clockwise, and the inclined rods 18 on both sides of the scraper plate 13 will deflect along the scraper plate 13, causing the impurities between the right inclined rod 18 and the scraper plate 13 to fall along the right inclined rod 18 and fall between the baffle 7 and the side wall of the box body 1, completing the impurity processing and collection operation; During the process of adding sewage, the injected sewage is located in the area between the box body 1 and the two baffles 7, and the distance between the liquid level of the injected sewage and the upper end surface of the baffle 7 is small.

[0015] A stirring assembly is installed in the box body 1, and the stirring assembly includes a fixed round rod 26 fixedly connected to the two baffles 7. A threaded barrel 33 is fixedly connected between the two fixed round rods 26. A threaded rod 32 is threadedly connected to the threaded barrel 33, and the threaded rod 32 passes through the threaded barrel 33. A circular plate 31 is fixedly connected to the lower side of the threaded rod 32. A plurality of transverse stirring plates 30 are fixedly connected to the outer circumference of the circular plate 31. The upper side of the threaded rod 32 is rotatably connected to the limit rod 24. The upper side of the limit rod 24 is fixedly connected to the limit rod 24. The positioning plate 19 is slidably connected to the limiting plate 19 and the two baffles 7. A third spring 34 is fixedly connected between the limiting rod 24 and the threaded cylinder 33. A plurality of rotating rings 27 are rotatably connected to the outer side of the fixed round rod 26. A vertical stirring plate 29 is fixedly connected to the outer side of each rotating ring 27. A fixed rod 28 is also fixedly connected to the outer side of each rotating ring 27. The lower side of the limiting plate 19 is fixedly connected to the pressing plate 52 through the first connecting rod 25. A torsion spring is fixedly connected between the rotating ring 27 and the fixed round rod 26. First, in the initial state, the pressing plate 52 and the fixed rod 28 are against each other, and the vertical stirring rod is staggered as shown in Figure 8. When the scraper plate 13 moves up and down, under the cooperation of the third spring 34, the scraper plate 13 and the limit plate 19 are against each other, driving the limit plate 19 and the limit rod 24 to move up and down, and the limit rod 24 drives the threaded rod 32 to move up and down. Since the threaded rod 32 and the threaded barrel 33 are threadedly connected, the threaded rod 32 that moves up and down will also rotate. Therefore, the threaded rod 32 will drive the circular plate 31 and the horizontal stirring plate 30 to move up and down as a whole. During this process, the circular plate 31 and the horizontal stirring plate 30 rotate to form a stirring operation on the sewage in the water tank, accelerate the mixing efficiency of the coagulant, flocculant and catalyst with the sewage, and thus greatly accelerate the sewage treatment efficiency. At the same time, the limit plate 19 that moves up and down will also pass through the first connecting rod 25 drives the pressing plate 52 to move up and down, and the pressing plate 52 and the fixed rod 28 are against each other, which causes the fixed rod 28 and the rotating ring 27 to rotate around the fixed round rod 26. The torsion spring is deformed, and the rotating ring 27 drives the vertical stirring plate 29 to rotate, which can form stirring of the sewage in two different directions, which can greatly accelerate the mixing efficiency of the coagulant, flocculant and catalyst with the sewage. In the process of sewage treatment, the possibility of large particles accumulating on the surface of the flotation machine 5 is reduced, and the inclined rod 18 can collect more impurities. In this process, when the vertical stirring plates 29 are deflected in the direction of approaching each other, the sewage has a tendency to move upward, reducing the possibility of impurities in the sewage settling downward under the action of their own gravity, thereby increasing the possibility of the inclined rod 18 collecting more impurities, and further improving the treatment effect of impurities in the sewage.

[0016] A quantitative observation assembly is installed in the box body 1, and the quantitative observation assembly includes a glass cylinder 42. The side wall of the glass cylinder 42 is fixedly connected to the second rack 50 through a second connecting rod 43. The outer side of the rotating shaft 9 is fixedly connected to the second gear 35. The second gear 35 is meshed with the second rack 50. The outer side of the rotating shaft 9 is also fixedly connected to the cam 36. The bottom of the glass cylinder 42 is slidably connected to a baffle 44. The upper side of the baffle 44 is fixedly connected to a baffle rod 45. The side wall of the glass cylinder 42 is fixedly connected to a cross bar 46. The lower side of the cross bar 46 is fixedly connected to a third connecting rod 48. The third connecting rod 48 is slidably connected to the side wall of the box body 1, and a sixth spring 47 is fixedly connected between the third connecting rod 48 and the box body 1. The side wall of the baffle rod 45 is fixedly connected to a push plate through a fourth connecting rod 51. A seventh spring 49 is fixedly connected between the baffle rod 45 and the cross bar 46. In the process of sewage treatment, the rotation direction of the motor 6 can be manually adjusted by the controller, that is, the motor 6 rotates clockwise or counterclockwise. This is the conventional use of the motor 6 and no unnecessary details are given. Figure 11From the perspective of , when the motor 6 rotates counterclockwise, the motor 6 will drive the rotating shaft 9 to rotate clockwise through the first gear 15, and the rotating shaft 9 will drive the cam 36 and the second gear 35 to rotate clockwise, and the second gear 35 will drive the second rack 50 to move upward, and the second rack 50 will drive the glass cylinder 42 to move upward through the second connecting rod 43, so that the glass cylinder 42 is removed from the sewage. At this time, the staff can observe the actual situation of the sewage in the glass cylinder 42, judge the treatment situation of the sewage in the box body 1, and then perform corresponding treatment, and in the process of the glass cylinder 42 moving upward, when the glass cylinder 42 starts to move, the rotating cam The wheel 36 will abut against the push plate, causing the push plate to drive the blocking rod 45 and the blocking plate 44 to move as a whole through the fourth connecting rod 51, so that the lower side of the glass cylinder 42 and the box body 1 are in a communicating state. When the upper end of the glass cylinder 42 is just moved out of the sewage, the rotating cam 36 will not abut against the push plate. At this time, the lower end of the glass cylinder 42 is in a sealed state until the glass cylinder 42 is extended into the sewage again by adjusting the rotation direction of the motor 6. The lower end of the glass cylinder 42 continues to communicate with the sewage, resulting in no sewage left over from the last observation remaining in the glass cylinder 42 each time the sewage in the glass cylinder 42 is observed, reducing the mutual influence of each observation.

[0017] A positioning plate 40 is fixedly connected to the side wall of the box body 1. The lower side of the positioning plate 40 is slidably connected to the movable vibration plate 37 via a fifth spring 41. The lower side of the movable vibration plate 37 is slidably connected to the contact vibration plate 39 via a fourth spring 38. During the rotation of the cam 36, the cam 36 and the movable vibration plate 37 are offset against each other. Under the action of the fifth spring 41, the movable vibration plate 37 moves up and down. The movable vibration plate 37 drives the contact vibration plate 39 to move up and down through the fourth spring 38. When the scraper plate 13 is deflected, the scraper plate 13 will move to the lower side of the contact vibration plate 39. The up and down moving contact vibration plate 39 and the scraper plate 13 are offset against each other, which will cause the scraper plate 13 to vibrate, reducing the possibility of impurities sticking to the scraper plate 13.

[0018] The lower side of the box body 1 is fixedly connected to a plurality of legs, and the lower side of each leg is fixedly connected to a shock-absorbing plate; Improve the overall stability of the box 1.

[0019] In the present invention, when sewage treatment is required, the sewage to be treated is first introduced into the box body 1 through the fixed pipe 3, and an appropriate amount of coagulant and flocculant is poured into the sewage. Then, the box cover 2 is closed and the motor 6 is started. The motor 6 drives the reciprocating screw 8 to rotate, and the reciprocating screw 8 drives the moving frame 10 to move back and forth. The moving frame 10 drives the slide 12 to move along the slide 11. When the slide 12 is located in the straight part, the moving frame 10 drives the slide 12 to move. The slide 12 passes through the square rod 16 and the square tube. 17 and the first spring drive the scraper plate 13 to move, the reciprocating screw 8 also drives the rotating shaft 9 to rotate through the first gear 15, the rotating shaft 9 drives the extension plate to rotate, and the extension plate and the cross plate 21 are offset to drive the cross plate 21 to move, that is, when the rotating shaft 9 and the extension plate rotate clockwise, the extension plate drives the right cross plate 21 to move downward, and drives the left cross plate 21 to move upward, eventually causing the right control plate 14 to move downward, the left control plate 14 to move upward, and the right control plate 14 and the contact rod 20 is in contact with each other, and drives the contact round rod 20 to move downward, and the contact round rod 20 drives the scraper plate 13 to move downward relative to the slide plate 12, thereby causing the first spring to deform, and the scraper plate 13 drives the inclined rod 18 to move downward. The area formed by the multiple inclined rods 18 and the side wall of the scraper plate 13 is similar to a colander, so that impurities can be collected. When the scraper plate 13 and the baffle 7 are in contact with each other, the scraper plate 13 moves upward relative to the slide plate 12 under the obstruction of the baffle 7 until the scraper plate 13 and the baffle 7 are disconnected, and then The rear scraper plate 13 and the baffle plate 7 continue to move. When the slide plate 12 moves to the arc-shaped part of the chute 11, under the power of the moving frame 10, the slide plate 12 continues to move along the chute 11, causing the slide plate 12 and the scraper plate 13 to deflect as a whole, and the inclined rods 18 on both sides of the scraper plate 13 deflect along the scraper plate 13, causing the impurities between the right inclined rod 18 and the scraper plate 13 to fall along the right inclined rod 18 and fall between the baffle plate 7 and the side wall of the box body 1, completing the impurity processing and collection operation; When the scraper plate 13 moves up and down, the scraper plate 13 and the limit plate 19 are offset from each other, driving the limit plate 19 and the limit rod 24 to move up and down. The limit rod 24 drives the threaded rod 32 to move up and down. The threaded rod 32 will drive the circular plate 31 and the horizontal stirring plate 30 to move up and down as a whole. The circular plate 31 and the horizontal stirring plate 30 rotate to form a stirring operation on the sewage in the water tank, accelerating the mixing efficiency of the coagulant, flocculant and catalyst with the sewage, thereby greatly accelerating the sewage treatment efficiency. The limit plate 19 will also drive the pressing plate 52 to move up and down through the first connecting rod 25. The pressing plate 52 and the fixed rod 28 are offset from each other, which will cause the fixed rod 28 and the rotating ring 27 to fix the circular rod 26. The center of the air flotation machine 5 rotates, and the rotating ring 27 drives the vertical stirring plate 29 to rotate, which can form stirring of the sewage in two different directions, which can greatly accelerate the mixing efficiency of the coagulant, flocculant and catalyst with the sewage. In the process of sewage treatment, the possibility of large particles accumulating on the surface of the flotation machine 5 is reduced, so that the inclined rod 18 can collect more impurities. In addition, in this process, when the vertical stirring plates 29 deflect in the direction of approaching each other, the sewage will tend to move upward, reducing the possibility of impurities in the sewage settling downward under the action of their own gravity, thereby increasing the possibility of the inclined rod 18 collecting more impurities, and further improving the treatment effect of impurities in the sewage. In the process of sewage treatment, when the motor 6 rotates counterclockwise, the motor 6 drives the rotating shaft 9 to rotate clockwise through the first gear 15, and the rotating shaft 9 drives the cam 36 and the second gear 35 to rotate clockwise. The second gear 35 drives the second rack 50 to move upward, and the second rack 50 drives the glass cylinder 42 to move upward through the second connecting rod 43, so that the glass cylinder 42 is removed from the sewage. When the glass cylinder 42 starts to move, the rotating cam 36 will resist the push plate, causing the push plate to drive the blocking rod 45 and the fourth connecting rod 51 to move upward. The blocking piece 44 moves as a whole, so that the lower side of the glass cylinder 42 and the box body 1 are in a state of communication. When the upper end of the glass cylinder 42 is just moved out of the sewage, the rotating cam 36 will not abut against the push plate. At this time, the lower end of the glass cylinder 42 is in a sealed state until the glass cylinder 42 is extended into the sewage again by adjusting the rotation direction of the motor 6. The lower end of the glass cylinder 42 continues to communicate with the sewage, thereby resulting in that each time the sewage in the glass cylinder 42 is observed, no sewage left over from the last observation will remain in the glass cylinder 42, reducing the mutual influence of each observation; During the rotation of the cam 36, the movable vibration plate 37 moves up and down, and the movable vibration plate 37 drives the contact vibration plate 39 to move up and down through the fourth spring 38. When the scraper plate 13 is deflected, the scraper plate 13 will move to the lower side of the contact vibration plate 39. The up and down moving contact vibration plate 39 and the scraper plate 13 will resist each other, causing the scraper plate 13 to vibrate, reducing the possibility of impurities sticking to the scraper plate 13.
