Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a petrochemical wastewater treatment device. Background Art

[0002] The main pollutants in petrochemical wastewater are complex compounds composed of cyclic and non-cyclic saturated monobasic acids, which are difficult to volatilize and difficult to biodegrade. Therefore, they need to be optimized in the pretreatment stage before they can be easily resolved in the process of deep treatment. Petrochemical wastewater contains a variety of chemical substances. In the pretreatment stage, chemical methods are mostly used to add various chemical flocculants or polymer flotation agents to make the combination of the substances to be removed float to the water surface for removal.

[0011] Preferably, the hollow threaded rod passes through a side wall of the protective cover and is connected to the side wall of the protective cover through a bearing, one end of the hollow threaded rod is connected to a side wall of the movable tooth through a bearing, the hollow threaded rod and the movable tooth are both sleeved on the outside of the connecting rod and are slidably connected to the connecting rod, and one end of the connecting rod is connected to a side wall of the flocculation tank through a bearing.

[0012] Preferably, the screw rod and the transmission rod both penetrate through the two side walls of the flocculation tank and are connected to the two side walls of the flocculation tank via bearings.

[0015] The embodiments of the present invention have the following advantages:

[0016] 1. The floccules are pushed to move to the floc discharge port by the floc-pushing water filter plate. When the connecting columns on both sides of the floc-pushing water filter plate slide along the floc-pushing flat track toward the inside of the floc-pushing track, the bottom of the floc-pushing water filter plate contacts the slope of the anti-drainage inclined block, and the floc-pushing water filter plate cooperates with the slope of the anti-drainage inclined block and the connecting columns with the floc-pushing track, so that the floc-pushing water filter plate pushes the floccules out of the floc discharge port. Since the floccules are pushed obliquely upward at this time, the purified petrochemical wastewater is filtered through the floc-pushing water filter plate, and only the floccules are pushed out of the flocculant tank through the floc discharge port, thereby preventing the discharge of a large amount of purified petrochemical wastewater;

[0017] 2. When the flocculation pushing and filtering plate returns, the cooperation between the connecting column and the track changing block makes the slide return to the right end of the flocculation pushing and parallel pushing track along the anti-reverse pushing track. The flocculation pushing and filtering plate is lifted upward through the connecting column to prevent the flocculation pushing and filtering plate from pushing the unexcluded floccules back to the right side of the flocculation tank, so that the floccules can only be pushed out in one direction, which is convenient for the subsequent centralized treatment of the discharged floccules. At the same time, when the connecting column moves to the left along the flocculation pushing and parallel pushing track next time, the connecting column can be directly lifted up when it contacts the track changing block without interfering with the movement of the connecting column, thereby not affecting the pushing and filtering plate to push the floccules.

[0018] 3. When the main gear rotates, it cooperates with the movable teeth below to drive the driving block to rotate. The driving block rotates through the driven block to drive the transmission teeth to rotate. The transmission teeth rotate and drive the mixing transmission teeth to rotate. The mixing transmission teeth rotate and drive the stirring blades through the transmission rod to stir and mix the petrochemical wastewater and flocculant in the flocculation tank, which is convenient for the petrochemical wastewater and flocculant to be fully mixed and the petrochemical wastewater to be fully flocculated.

DETAILED DESCRIPTION

[0029] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are 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.

[0031] The deflocculation mechanism includes a power component, a deflocculation agent mixing component, and a deflocculation pushing component. The power component includes a protective cover 10, which is fixedly arranged on a side wall of the flocculation tank 1. A transmission shaft 12 is inserted into the protective cover 10, and a main gear 13 is fixedly sleeved on the outside of the transmission shaft 12. A driving unit is provided at the top and bottom of the main gear 13. The driving unit includes a movable tooth 14, which is meshed with the main gear 13. A driving block 15 is fixedly arranged on one side of the movable tooth 14, and a hollow threaded rod 16 is arranged on the other side of the movable tooth 14. A connecting rod 19 is inserted into the inside of the movable tooth 14, and a transmission tooth 18 is fixedly arranged on the outside of the connecting rod 19. A driven block 17 is fixedly arranged on one side of the transmission tooth 18.

[0032] In this embodiment, in order to discharge the floating floccules and prevent the discharge of a large amount of purified wastewater, the power assembly is adjusted so that the driving block 15 in the upper driving unit fits with the driven block 17. When the main gear 13 rotates, the driving block 15 is driven to rotate through the upper movable tooth 14. The driving block 15 rotates and drives the transmission tooth 18 to rotate through the driven block 17. The rotation of the transmission tooth 18 provides power to the floccules pushing assembly, so that the floccules pushing and filtering plate 24 in the floccules pushing assembly pushes the floccules to move toward the floccules discharge port 8. When the links on both sides of the floccules pushing and filtering plate 24 are connected, the floccules pushing and filtering plate 24 are connected. When the connecting column 26 slides along the flocculation pushing track 2 toward the inside of the flocculation pushing track 3, the bottom of the flocculation pushing filter plate 24 contacts the slope of the anti-drainage inclined block 9, and the flocculation pushing filter plate 24 pushes the floccules out of the floccules discharge port 8 through the cooperation of the flocculation pushing filter plate 24 and the slope of the anti-drainage inclined block 9 and the connecting column 26 and the flocculation pushing track 3. Since the floccules are pushed obliquely upward at this time, the purified petrochemical wastewater is filtered through the flocculation pushing filter plate 24, and only the floccules are pushed out of the flocculation tank 1 through the floccules discharge port 8, thereby preventing the discharge of a large amount of purified petrochemical wastewater;

[0033] Among them, in order to achieve the purpose of improving the mixing effect of petrochemical wastewater and flocculant, the device adopts the following technical solutions: the flocculant removal mixing component includes a mixing transmission tooth 27, the mixing transmission tooth 27 is meshed with the bottom transmission tooth 18, the mixing transmission tooth 27 is fixedly inserted with a transmission rod 28 inside, and the transmission rod 28 is fixedly sleeved with a stirring blade 29 outside, and when the main gear 13 rotates, the driving block 15 is driven to rotate by the movable tooth 14 below, and the driving block 15 rotates through the driven block 17 to drive the transmission tooth 18 to rotate, and the transmission tooth 18 rotates to drive the mixing transmission tooth 27 to rotate, and the mixing transmission tooth 27 rotates through the transmission rod 28 to drive the stirring blade 29 to rotate, so as to stir and mix the petrochemical wastewater and flocculant inside the flocculation tank 1, so as to facilitate the full mixing of the petrochemical wastewater and the flocculant, and facilitate the full flocculation of the petrochemical wastewater;

[0034] Among them, in order to achieve the purpose of preventing the occurrence of reverse push of flocculants, the present device adopts the following technical solutions: the flocculant pushing component includes a flocculant pushing transmission tooth 20, which is meshed with the top transmission tooth 18, and a screw rod 21 is fixedly inserted inside the flocculant pushing transmission tooth 20, and a slider 22 is sleeved on the outside of the screw rod 21, and a baffle 23 is fixedly provided on one side of the slider 22, and a flocculant pushing water filter plate 24 is sleeved on the outside of the slider 22, and a slide groove 25 is provided inside the flocculant pushing water filter plate 24, and connecting columns 26 are fixedly provided on both sides of the flocculant pushing water filter plate 24, and the track component includes a flocculant pushing horizontal push track 2, which is opened on one side wall of the flocculant pushing horizontal push track 2, and a flocculant pushing pushing track 3 is provided at one end of the flocculant pushing horizontal push track 2, and a track change block obstacle avoidance groove 4 is provided inside the flocculant pushing horizontal push track 2, and an anti-reverse push track 5 is provided at the other end of the flocculant pushing horizontal push track 2, and a rotating shaft 6 is fixedly connected to the anti-reverse push track 5, and a track change block 7 is sleeved on the outside of the rotating shaft 6, and the screw rod 21 and the transmission rod 28 both penetrate the flocculant pushing pool 1 The two side walls are connected to the two side walls of the flocculation tank 1 through bearings, and the slider 22 is sleeved on the outside of the screw rod 21 and connected to the screw rod 21 through a three-dimensional cam pair. The slider 22 passes through the slide groove 25 and is slidably connected to the slide groove 25. The connecting column 26 extends into the interior of the flocculation pushing track 2 and is slidably connected to the flocculation pushing track 2. When the flocculation filtering plate 24 returns, the connecting column 26 cooperates with the track changing block 7 to make the slide groove 25 return to the right end of the flocculation pushing track 2 along the anti-reverse push track 5. The flocculation filtering plate 24 is lifted up through the connecting column 26 to prevent the flocculation filtering plate 24 from pushing the unremoved flocculation back to the right side of the flocculation tank 1, so that the flocculation can only be pushed out in one direction, which is convenient for the subsequent centralized treatment of the discharged flocculation. At the same time, when the connecting column 26 moves to the left along the flocculation pushing track 2 next time, the connecting column 26 can be directly lifted up when it contacts the track changing block 7, which will not interfere with the movement of the connecting column 26, and thus will not affect the pushing of the flocculation filtering plate 24 to push the flocculation;

[0035] Among them, in order to achieve the purpose of controlling the operation of the flocculant mixing component or the flocculant pushing component, the present device adopts the following technical solutions: a motor 11 is fixedly arranged on one side of the protective cover 10, the output end of the motor 11 is fixedly connected to one end of a transmission shaft 12, the transmission shaft 12 penetrates one side wall of the protective cover 10 and is connected to one side wall of the protective cover 10 through a bearing, the other end of the transmission shaft 12 is connected to one side wall of the flocculation tank 1 through a bearing, a hollow threaded rod 16 penetrates one side wall of the protective cover 10 and is connected to one side wall of the protective cover 10 through a bearing, one end of the hollow threaded rod 16 is connected to one side wall of the movable tooth 14 through a bearing, the hollow threaded rod 16 and the movable tooth 14 are both sleeved on the outside of the connecting rod 19 and are slidably connected to the connecting rod 19, one end of the connecting rod 19 is connected to one side wall of the flocculation tank 1 through a bearing, and the starting motor Machine 11, the motor 11 rotates through the transmission shaft 12 to drive the main gear 13 to rotate, the main gear 13 rotates to drive the two upper and lower movable teeth 14 to rotate, the movable teeth 14 rotate to drive the driving block 15 to rotate, when the stirring blade 29 needs to work, the hollow threaded rod 16 at the bottom is rotated clockwise, and when the hollow threaded rod 16 rotates, the movable teeth 14 are pushed to move closer to the transmission teeth 18 through the threaded cooperation, thereby driving the rotating driving block 15 to fit with the driven block 17. At this time, the rotation of the main gear 13 drives the driving block 15 to rotate through the movable teeth 14 below, and the driving block 15 rotates through the driven block 17 to drive the transmission teeth 18 to rotate, and the transmission teeth 18 rotate through the mixed transmission teeth 27 to drive the transmission rod 28 to rotate. Similarly, when the screw rod 21 needs to rotate, the upper hollow threaded rod 16 can be adjusted.

[0036] The use process of the present invention is as follows: when using the present invention, connect an external power supply, add petrochemical wastewater and corresponding floating flocculants into the flocculation tank 1 and add the petrochemical wastewater to a horizontal plane close to the top of the anti-drainage inclined block 9, start the motor 11, and the motor 11 rotates through the transmission shaft 12 to drive the main gear 13 to rotate. The main gear 13 rotates to drive the two upper and lower movable teeth 14 to rotate. The movable teeth 14 rotate to drive the driving block 15 to rotate. When the stirring blade 29 needs to work, rotate the hollow threaded rod 16 at the bottom clockwise. When the hollow threaded rod 16 rotates, the movable teeth 14 are pushed toward the transmission teeth 18 through the threaded cooperation, thereby driving the rotating driving block 15 to fit with the driven block 17. At this time, the rotation of the main gear 13 is driven by the movable teeth below. 14 drives the driving block 15 to rotate, the driving block 15 rotates and drives the transmission tooth 18 to rotate through the driven block 17, the transmission tooth 18 rotates and drives the mixing transmission tooth 27 to rotate, the mixing transmission tooth 27 rotates and drives the stirring blade 29 to rotate through the transmission rod 28, and the petrochemical wastewater and the flocculant in the flocculation tank 1 are stirred and mixed, so that the petrochemical wastewater and the flocculant are fully mixed. Similarly, when it is necessary to clean the flocculent bodies that float on the flocculation, the above operations are synchronized, so that the rotation of the main gear 13 drives the driving block 15 to rotate through the upper movable tooth 14, the driving block 15 rotates and drives the transmission tooth 18 to rotate through the driven block 17, the transmission tooth 18 rotates and drives the pushing transmission tooth 20 to rotate, and the pushing transmission tooth 20 rotates through the cooperation of the screw rod 21 and the slider 22 The slider 22 moves back and forth laterally. When the slider 22 drives the flocculation-pushing filter plate 24 to move toward the flocculation discharge port 8, the bottom of the flocculation-pushing filter plate 24 extends below the horizontal plane of the petrochemical wastewater, so that the flocculation-pushing filter plate 24 can push the floccules to move toward the flocculation discharge port 8. When the connecting columns 26 on both sides of the flocculation-pushing filter plate 24 slide along the flocculation-pushing track 2 toward the inside of the flocculation-pushing track 3, the bottom of the flocculation-pushing filter plate 24 contacts the slope of the anti-drainage inclined block 9, and the cooperation between the flocculation-pushing filter plate 24 and the slope of the anti-drainage inclined block 9 and the connecting columns 26 and the flocculation-pushing track 3 enables the flocculation-pushing filter plate 24 to push the floccules out of the flocculation discharge port 8. Since the floccules are pushed obliquely upward at this time, the purified petrochemical wastewater is filtered through the flocculation-pushing filter plate 24. The floccules are pushed out of the flocculation tank 1 through the flocculation discharge port 8 to prevent the discharge of a large amount of purified petrochemical wastewater. When the flocculation pushing and filtering plate 24 returns, the connecting column 26 and the track changing block 7 cooperate to make the slide 25 return to the right end of the flocculation pushing and parallel pushing track 2 along the anti-reverse pushing track 5. The flocculation pushing and filtering plate 24 is lifted up through the connecting column 26 to prevent the flocculation pushing and filtering plate 24 from pushing the undischarged floccules back to the right side of the flocculation tank 1, so that the floccules can only be pushed out in one direction, which is convenient for the subsequent centralized treatment of the discharged floccules. At the same time, the next time the connecting column 26 moves to the left along the flocculation pushing and parallel pushing track 2, the connecting column 26 can be directly lifted up when it contacts the track changing block 7 without interfering with the movement of the connecting column 26, and thus will not affect the pushing of the floccules by the flocculation pushing and filtering plate 24.
