[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to solve the technical problem of uneven dispersion of reagents during wastewater treatment, resulting in poor mixing effect between wastewater and reagents, which affects the wastewater treatment effect, such as Figures 1-14 As shown, the following preferred technical solutions are provided: A fine chemical production process wastewater treatment device includes a first treatment tank 1, a sedimentation tank 2 is fixedly provided on the outer wall of the first treatment tank 1, the sedimentation tank 2 is used for preliminary treatment of the wastewater, and the first treatment tank 1 is used for secondary treatment of the wastewater after precipitation. The two cooperate to achieve graded treatment of the wastewater, and at the same time facilitate the temporary storage of wastewater at different treatment stages. A through groove 21 is provided between the first treatment tank 1 and the sedimentation tank 2, a cover plate 22 is fixedly provided on the top of the sedimentation tank 2, the cover plate 22 is used to seal the sedimentation tank 2, and a first filling pipe 23 is provided in the cover plate 22. The first filling pipe 23 is used to add flocculant, so that impurities such as suspended particles and colloids in the wastewater are condensed to form larger flocs under the action of the flocculant, and the impurities are separated from the wastewater by static sedimentation, which also reduces the load of pollutants for the subsequent secondary treatment of the first treatment tank 1. The bottom of the sedimentation tank 2 is evenly connected with a plurality of first sewage pipes 24. A second sewage pipe 25 is provided at the bottom of the first treatment tank 1. Valves are installed on the first sewage pipe 24 and the second sewage pipe 25, which can facilitate the discharge of impurities and residues after precipitation. A first filter component 3 is provided in the cover plate 22. The first filter component 3 is used to filter large particles of impurities when the wastewater enters the sedimentation tank 2. At the same time, the supernatant after static precipitation can be pumped into the first treatment tank 1 for secondary treatment. A driving component 4 is fixedly provided on one side of the cover plate 22, and a rotating component 5 is provided in the driving component 4. A drug injection component 6 is fixedly provided on one side of the cover plate 22, and the drug injection component 6 is provided in the rotating component 5. A spraying component 7 is provided in the rotating component 5. The first treatment tank 1 is connected to the second filter component 8. The second filter component 8 can facilitate the completion of secondary treatment, and the supernatant after static precipitation is pumped into the component to finely filter the wastewater and achieve graded treatment of wastewater.

[0026] When treating wastewater from fine chemical production processes, the wastewater is initially filtered through the first filter assembly 3 to facilitate filtering out large particle impurities. The filtered wastewater enters the sedimentation tank 2, and then the first filling pipe 23 is used to fill the sedimentation tank 2 with flocculant, so that the suspended particles and colloids in the wastewater are condensed to form larger flocs under the action of the flocculant, and the impurities are separated from the wastewater by static sedimentation, which also reduces the pollutant load for the subsequent secondary treatment of the first treatment tank 1. At this time, the first filter assembly 3 is used to pump the supernatant after static sedimentation into the first treatment tank 1 through an external controller, and then the expelling agent is used to pump the supernatant after static sedimentation into the first treatment tank 1 through an external controller. The moving component 4 slowly contracts and extends back and forth. During this process, the external controller causes the injection component 6 to pump the agent into the rotating component 5, and generates an atomized spiral liquid flow through the spray component 7. The agent is converted into tiny droplets through atomization, thereby increasing the contact area with the wastewater. At the same time, the spray component 7 rotates as a whole, making it convenient to utilize the rotation of the spiral liquid flow and the trajectory of the rotating spraying to break the static stratification of the wastewater and perform dynamic diffusion, thereby reducing mixing dead corners and allowing the agent to penetrate more evenly into various areas of the wastewater. This not only accelerates the reaction rate with pollutants, but also avoids the waste caused by local accumulation of agents, thereby improving the agent utilization rate and treatment efficiency.

[0027] At the same time, the spiral liquid flow can also stir the wastewater and the agent. Compared with traditional mechanical stirring, it can reduce local shear force, avoid destroying the formed flocs, and further increase the wastewater treatment effect. By driving the component 4 to slowly contract and extend back and forth, the rotating component 5 rotates while driving the spray component 7 to perform a periodic reciprocating motion of the spiral upward and downward, so that the agent can form a three-dimensional path coverage. Compared with the existing fixed or single-direction spraying, it can avoid dead corners in treatment, so that wastewater of different depths and different areas can fully contact with the agent, further enhancing the mixing effect. After the treatment is completed, the wastewater is allowed to settle. After the sedimentation is completed, the supernatant after settling is pumped into the component through the second filter component 8 to finely filter the wastewater. A linkage component 9 is provided at the bottom of the cover plate 22, and an elastic component 10 is provided in the linkage component 9. A stirring component 20 is slidingly provided on the top of the first treatment tank 1.

[0028] When the first filling pipe 23 adds flocculant into the sedimentation tank 2 and stirring is required, the elastic component 10 is extended through an external controller, and the linkage component 9 is synchronously driven to rotate through the rotation of the rotating component 5 until the elastic component 10 is in contact with the stirring component 20, so that the stirring component 20 slides slowly on the top of the first treatment tank 1. During the secondary treatment, the wastewater and flocculant newly entering the sedimentation tank 2 can be stirred synchronously, thereby shortening the wastewater treatment cycle, reducing the use cost, and improving work efficiency. At the same time, the flocculant and wastewater are fully mixed, which is conducive to forming a more stable floc and improving the sedimentation effect.

[0029] like Figure 1-Figure 5 As shown, the first filter assembly 3 includes a liquid inlet box 31 arranged in the cover plate 22, and a filter screen 32 is fixedly connected to the liquid inlet box 31. The filter screen 32 is used to filter large particles of impurities to facilitate the protection of subsequent processing equipment. The top of the liquid inlet box 31 is connected with a liquid inlet pipe 33, and a first extraction pipe 34 is arranged in the cover plate 22. One end of the first extraction pipe 34 extends into the sedimentation tank 2, and a first water pump 35 is installed on the top of the cover plate 22. The first extraction pipe 34 is connected to the liquid inlet of the first water pump 35, and the liquid outlet of the first water pump 35 is connected with a first connecting pipe 36. The first connecting pipe 36 is arranged in the cover plate 22, and one end of the first connecting pipe 36 is placed directly above the first treatment tank 1. The lowest surface of the first connecting pipe 36 is higher than the top surface of the first treatment tank 1.

[0030] like Figure 1-Figure 3 、 Figure 5 and Figure 7-Figure 8 As shown, the drive assembly 4 includes two L-shaped mounting plates 41 relatively connected to the top of the cover plate 22, and an electric push rod 42 is installed on one side of the two L-shaped mounting plates 41. The movable end of the electric push rod 42 is fixedly connected to a lifting plate 43, and the lifting plate 43 is slidably connected to the two L-shaped mounting plates 41 respectively.

[0031] like Figure 1 、 Figure 3 、 Figure 5-Figure 9 and Figure 13 As shown, the rotating assembly 5 includes a U-shaped mounting plate 51 fixedly connected to one side of the lifting plate 43, a threaded block 52 fixedly connected to one side of the L-shaped mounting plate 41, a threaded hollow rod 53 internally threaded on the threaded block 52, one end of the threaded hollow rod 53 is rotatably connected to the U-shaped mounting plate 51, an L-shaped rotating tube 54 is fixedly connected to the bottom of the threaded hollow rod 53, the threaded hollow rod 53 is communicated with the L-shaped rotating tube 54, and the L-shaped rotating tube 54 is rotatably connected to the lifting plate 43. After the addition of the agent is completed, the electric push rod 42 is in a retracted state. At this time, the lowest surface of the L-shaped rotating tube 54 is much higher than the wastewater liquid level, which is convenient for avoiding the adhesion of impurities and reducing the frequency of cleaning and maintenance.

[0032] like Figure 1-Figure 2 and Figure 8As shown, the injection assembly 6 includes a medicine box 61 fixedly connected to the top of the cover plate 22, the top of the medicine box 61 is connected to a second filling pipe 62, the bottom of the medicine box 61 is connected to a second extraction pipe 63, a booster water pump 64 is installed on the top of the cover plate 22, the second extraction pipe 63 is connected to the water inlet of the booster water pump 64, the water outlet of the booster water pump 64 is connected to a hose 65, and the other end of the hose 65 is connected to a bend pipe 66, one end of the bend pipe 66 is connected to a rotary joint 67, and the other end of the rotary joint 67 is connected to a second connecting pipe 68, the second connecting pipe 68 is rotatably connected to the rotary joint 67, one end of the second connecting pipe 68 is connected to the threaded hollow rod 53, and the rotary joint 67 is fixedly connected to the U-shaped mounting plate 51.

[0033] like Figure 6 and Figure 9-10 As shown, the spray assembly 7 includes a support rod 71 fixedly connected to the L-shaped rotating tube 54, a rotating shaft 72 is rotatably connected to the support rod 71, one end of the rotating shaft 72 is fixedly connected to the fan blade 73, and the other end of the rotating shaft 72 is fixedly connected to the rotating plate 74, the rotating plate 74 is rotatably connected to the L-shaped rotating tube 54, a V-shaped liquid outlet pipe 75 is provided in the L-shaped rotating tube 54, one end of the V-shaped liquid outlet pipe 75 is connected to the atomizing nozzle 76, and one end of the atomizing nozzle 76 is connected to the spray pipe 77, and a plurality of arc grooves 78 are evenly arranged in the spray pipe 77.

[0034] like Figure 1 and Figure 14 As shown, the second filter assembly 8 includes a second treatment tank 81 arranged on one side of the first treatment tank 1, a second water pump 83 is installed on the top of the second treatment tank 81, the liquid inlet of the second water pump 83 is connected to the third extraction pipe 82, and the other end of the third extraction pipe 82 is connected to the first treatment tank 1, the liquid outlet of the second water pump 83 is connected to the third connecting pipe 84, and the other end of the third connecting pipe 84 is connected to the second treatment tank 81, a fixed plate 85 is fixedly connected in the second treatment tank 81, and a number of ceramic filter membranes 86 are fixedly connected in the fixed plate 85, and the bottom of the second treatment tank 81 is connected to a drain pipe 87, and a valve is installed on the drain pipe 87 to facilitate the discharge of treated water.

[0035] When treating the wastewater from the fine chemical production process, the wastewater enters the liquid inlet box 31 through the liquid inlet pipe 33, and is preliminarily filtered through the filter screen 32 to facilitate filtering out large particles of impurities. The filtered wastewater enters the sedimentation tank 2, and then the flocculant is pumped into the sedimentation tank 2 through the first filling pipe 23 by an external water pump, so that the suspended particles and colloids in the wastewater are condensed to form larger flocs under the action of the flocculant, and the impurities are separated from the wastewater by static sedimentation, which also reduces the pollutant load for the subsequent secondary treatment of the first treatment tank 1. At this time, through the external controller, the first water pump 35 pumps the supernatant after static sedimentation into the first treatment tank 1 through the first extraction pipe 34 and the first connecting pipe 36, and then through the external controller, the electric push rod 42 is reciprocated and slowly contracted and extended, driving the lifting plate 43, the threaded hollow rod 53 and the L-shaped rotating tube 54 to rise and fall. In this process, through the external controller , so that the booster water pump 64 pumps the agent into the threaded hollow rod 53 and the L-shaped rotating tube 54 through the agent box 61, the second extraction pipe 63, the hose 65, the elbow 66, the rotary joint 67 and the second connecting pipe 68, and generates an atomized spiral liquid flow through the cooperation between the atomizing nozzle 76, the spray pipe 77 and the arc groove 78. At the same time, the impact of the high-pressure water flow drives the fan blade 73 to rotate, so that the rotating shaft 72, the rotating plate 74, the V-shaped liquid outlet pipe 75, the atomizing nozzle 76 and the spray pipe 77 rotate, which facilitates the rotational spraying of the liquid medicine and facilitates the conversion of the agent into tiny droplets through atomization, thereby increasing the contact area with the wastewater. At the same time, the rotation of the spiral liquid flow and the trajectory of the rotary spraying facilitate breaking the static stratification of the wastewater and performing dynamic diffusion, thereby reducing mixing dead corners and allowing the agent to penetrate more evenly into various areas of the wastewater, which not only accelerates the reaction rate with the pollutants, but also avoids the waste caused by local accumulation of the agent, especially improving the utilization rate of the agent and the treatment efficiency.

[0036] At the same time, the spiral liquid flow can also stir the wastewater and the reagent. Compared with traditional mechanical stirring, it can reduce local shear force, avoid destroying the formed flocs, and further improve the wastewater treatment effect. The electric push rod 42 reciprocates and slowly contracts and extends, so that the threaded hollow rod 53 rotates up and down in the threaded block 52, driving the L-shaped rotating tube 54, the atomizing nozzle 76 and the liquid spray pipe 77 to continuously and slowly move upward and downward in a spiral. This cycle facilitates the formation of a three-dimensional path coverage for the reagent. Compared with existing fixed or single-directional injection, it can avoid treatment dead corners, so that wastewater at different depths and in different areas can fully contact the reagent, further enhancing the mixing effect. After the treatment is completed, the wastewater is allowed to settle. After the sedimentation is completed, the external controller causes the second water pump 83 to pump the supernatant after the settling into the second treatment tank 81 through the third extraction pipe 82 and the third connecting pipe 84, and filter it through the ceramic filter membrane 86, thereby finely filtering the wastewater and discharging it through the drain pipe 87.

[0037] In order to solve the technical problem that flocculants and wastewater are not easily mixed and the second-level treatment of wastewater is carried out simultaneously, such as Figure 3-Figure 6 and Figure 11-13 As shown, the following preferred technical solutions are provided: like Figure 3-Figure 6 and Figure 11-13 As shown, the linkage assembly 9 includes a fixed rod 91 fixedly connected to the inner wall of the first processing tank 1, a swivel 92 is rotatably connected to the top of the fixed rod 91, a rotating rod 93 is fixedly connected to the top of the swivel 92, a slider 94 is fixedly connected to the inner wall of the rotating rod 93, a slide groove 95 is opened on the outer wall of the L-shaped rotating tube 54, and the slider 94 is slidably connected to the slide groove 95.

[0038] like Figure 4 and Figure 11-12 As shown, the elastic component 10 includes a moving block 101 that is slidably connected to the rotating rod 93, two second springs 102 are fixedly connected to one side of the moving block 101, and the other ends of the two second springs 102 are fixedly connected to the inner wall of the rotating rod 93, an electromagnet 103 is installed on the inner wall of the rotating rod 93, and a magnet block 104 is provided on one side of the moving block 101.

[0039] like Figure 3-Figure 4 and Figure 11-12 As shown, the stirring assembly 20 includes a limit block 201 slidably connected to the top of the first processing tank 1, and an L-shaped connecting rod 203 is fixedly connected to one side of the limit block 201. The L-shaped connecting rod 203 is arranged in the through groove 21 to avoid movement interference. Several stirring rods 202 are evenly arranged in the L-shaped connecting rod 203.

[0040] When the first filling pipe 23 is used to add flocculant into the sedimentation tank 2 and stirring is required, the electromagnet 103 is controlled by an external controller to repel the magnet block 104, push the moving block 101 to extend the rotating rod 93, and at the same time stretch the two second springs 102. Through the rotation of the L-shaped rotating tube 54 and the cooperation between the slider 94 and the slide groove 95, the rotating rod 93 is synchronously driven to rotate until the moving block 101 is fitted with the L-shaped connecting rod 203, so that the L-shaped connecting rod 203 drives the limit block 201 to slide slowly on the top of the first treatment tank 1, thereby driving the L-shaped connecting rod 203 and several stirring rods 2 02 rotates in the sedimentation tank 2, which is convenient for synchronously stirring the wastewater and flocculant newly entering the sedimentation tank 2 during the secondary treatment of the wastewater, thereby shortening the wastewater treatment cycle, reducing the use cost, and improving work efficiency. At the same time, the flocculant and the wastewater are fully mixed, which is conducive to forming a more stable flocculent body and improving the sedimentation effect. During the rising process of the L-shaped rotating tube 54, the slider 94 slides in the slide groove 95. After stirring for a period of time, the external controller cancels the repulsion of the electromagnet 103 to the magnet block 104. At this time, the two second springs 102 are reset, driving the moving block 101 to reset.
