[0002] Wastewater treatment is a crucial step in the petrochemical production process. This wastewater often contains large amounts of suspended solids, oils, and other pollutants. If discharged directly into the environment without proper treatment, it can have serious impacts on ecosystems and human health. Traditional wastewater treatment methods, such as sedimentation, filtration, and flotation, have limitations in terms of treatment efficiency, separation effectiveness, and operating costs. With increasingly stringent environmental standards, efficiently and economically removing harmful substances from wastewater has become a major challenge facing the petrochemical industry.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0035] like Figure 1-Figure 5 、 Figure 7 As shown, a separation device for petrochemical production provided by one embodiment of the present invention is suitable for treating pollutants such as suspended solids in wastewater generated by the petrochemical industry. The device removes these solid particles to ensure that the wastewater meets environmental protection standards before discharge or reuse. The device includes an input pipeline 1 and also includes:

[0036] An outer net tube 36, wherein the front end base 2 and the rear end base 4 are respectively fixedly mounted on both ends of the outer net tube 36, and the middle of the front end base 2 and the rear end base 4 are respectively rotatably mounted with an end branch pipe 28 and an end support shaft 33, and an inner net tube 31 is fixed between the end branch pipe 28 and the end support shaft 33, and a spiral blade 30 is fixed on the outer side of the inner net tube 31 to cooperate with the inner wall of the outer net tube 36;

[0037] The drive assembly includes a rear fixing frame 5 fixed to the rear end base 4, a reducer 9 and a drive motor 10 are fixed to the rear fixing frame 5, and the output end of the drive motor 10 is connected to the end support shaft 33 through the reducer 9;

[0038] The infusion assembly includes a chamber 40 opened inside the front base 2, the input pipe 1 is connected to one end of the chamber 40, and the other end of the chamber 40 is connected to the area between the outside of the inner mesh tube 31 and the inside of the outer mesh tube 36 through a plurality of inlet holes 38 distributed circumferentially. An impeller 37 is also fixed to the end branch pipe 28 inside the chamber 40. The impeller 37 is conventionally arranged as needed to transport the wastewater.

[0039] Extrusion port 6, the rear end base 4 is circumferentially distributed with a plurality of extrusion ports 6 connected to the area between the outer side of the inner net tube 31 and the inner side of the outer net tube 36, and a telescopic control component is also fixedly installed on the rear end base 4, and the telescopic control component includes a support ring 8 sleeved on the end support shaft 33, and a plurality of blocking adjustment push-pull cylinders 11 are fixed on the side of the support ring 8 close to the rear end base 4, and the other end of the blocking adjustment push-pull cylinder 11 is fixedly connected to the rear end base 4, and an elastic blocking component 7 corresponding to the extrusion port 6 and used to block the extrusion port 6 is installed on the support ring 8;

[0040] like Figure 7As shown, the elastic blocking component 7 includes a plurality of blocking rods 43 distributed circumferentially and arranged corresponding to the extrusion port 6. One end of the blocking rod 43 is fixedly connected to the support ring 8, and the other end of the blocking rod 43 is fixedly installed with an inner plate 45. The inner plate 45 is slidably connected to the inner cavity of the blocking outer tube 41, and the blocking rod 43 is also sealed and slidably connected to the end of the blocking outer tube 41 to prevent the buffer medium 42 from flowing out; the outer side of the inner plate 45 is also circumferentially distributed with a plurality of through holes 46, and a spring 44 is also installed in the inner cavity of the blocking outer tube 41 on the side of the inner plate 45 away from the blocking rod 43. The inner cavity of the blocking outer tube 41 is also filled with a buffer medium 42. By setting the buffer medium 42 and the through hole 46, when the suspended solids are extruded from the extrusion port 6, the blocking outer cylinder 41 can be pushed to move, so that the buffer medium 42 passes through the through hole 46, which has a damping effect, so that the blocking outer cylinder 41 slowly returns to its original position under the elastic force of the spring 44, thereby ensuring the effect of squeezing the suspended solids out of the extrusion port 6.

[0041] In an embodiment of the present invention, the wastewater to be treated generated by the petrochemical industry is transported to the front end base 2 through the input pipe 1. Through the structural arrangement of the present invention, the drive assembly can drive the end support shaft 33 to rotate, and the inner net tube 31 and the end branch pipe 28 rotate synchronously, so that the spiral blades 30 push the liquid in the area between the outer side of the inner net tube 31 and the inner side of the outer net tube 36 to flow away from the front end base 2. During the pushing process, the suspended solids in the wastewater are separated from the wastewater, and the suspended solids are pushed by the spiral blades 30 to move toward the direction close to the rear end base 4, and the wastewater is efficiently filtered out from the inner net tube 31 and the outer net tube 36. In addition, the end branch 28 is limited to drive the infusion component to operate, and as the rotation speed of the spiral blade 30 increases, the rate at which the infusion component transports wastewater can be simultaneously increased, and efficient wastewater treatment can be achieved through reliable cooperation as a whole; the telescopic control component and the elastic blocking component 7 are arranged in combination, and the elastic blocking component 7 can elastically block the extrusion port 6, and the telescopic control component can control and adjust the size of the blocking force of the elastic blocking component 7 on the extrusion port 6, that is, when the pressure of the area between the outside of the inner mesh tube 31 and the inside of the outer mesh tube 36 near one end of the rear end base 4 exceeds the size of the blocking force of the elastic blocking component 7 on the extrusion port 6, the suspended solids in the filtered wastewater are squeezed out and discharged from the extrusion port 6, and the suspended solids and wastewater are fully and effectively separated through flexible control, thereby improving the overall treatment quality.

[0042] like Figure 4 and Figure 5As shown in FIG. 1 , as a preferred embodiment of the present invention, when the end support shaft 33 rotates, the infusion assembly is used to control the delivery of liquid in the input pipe 1 to the area between the outer side of the inner mesh tube 31 and the inner side of the outer mesh tube 36. A check valve 39 is also installed on the inlet hole 38. The check valve 39 is used to prevent wastewater in the chamber 40 from flowing through the inlet hole 38 to the area between the outer side of the inner mesh tube 31 and the inner side of the outer mesh tube 36, and to block the flow in the opposite direction.

[0043] When the end branch pipe 28 rotates, the impeller 37 can transport wastewater at a corresponding rate according to the rotation speed of the end branch pipe 28, thereby achieving efficient wastewater treatment; through the opened inlet hole 38 and the installed check valve 39, the wastewater is evenly distributed in the area between the outside of the inner mesh tube 31 and the inside of the outer mesh tube 36, and backflow is prevented, thereby improving reliability.

[0044] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, the output end of the drive motor 10 is connected and fixed to the input end of the reducer 9, and the output end of the reducer 9 is coaxial with the end support shaft 33 and is connected and fixed thereto; the drive motor 10 is used to drive the end support shaft 33 to rotate, so that the spiral blade 30 pushes the liquid in the area between the outside of the inner mesh tube 31 and the inside of the outer mesh tube 36 to flow in a direction away from the front end base 2.

[0045] The speed reducer 9 is used to adjust the power transmission to achieve appropriate speed and torque output, so that the drive motor 10 can stably and reliably rotate the drive end support shaft 33.

[0046] like Figure 1 、 Figure 4 、 Figure 6 and Figure 7 As shown in FIG. 1 , as a preferred embodiment of the present invention, the support ring 8 is coaxially arranged with the end support shaft 33 ; the blocking adjustment push-pull cylinder 11 is used to control the blocking force of the elastic blocking component 7 on the extrusion port 6 . The blocking force of the elastic blocking component 7 on the extrusion port 6 can be adjusted by adjusting the expansion and contraction of the blocking adjustment push-pull cylinder 11 .

[0047] like Figure 7 As shown, the extrusion outlet 6 is a conical structure, the large end (with a larger bottom diameter) of the extrusion outlet 6 faces the area between the outer side of the inner mesh tube 31 and the inner side of the outer mesh tube 36, and the small end (top) of the extrusion outlet 6 faces the elastic blocking component 7. The end of the sealing outer tube 41 close to the extrusion outlet 6 is a hemispherical shape with a diameter larger than the diameter of the small end of the extrusion outlet 6, so that the sealing outer tube 41 can reliably block the extrusion outlet 6 and facilitate the extrusion and discharge of suspended solids from the extrusion outlet 6.

[0048] The buffering medium 42 is silicone oil or mineral oil. Silicone oil has excellent thermal and chemical stability, low toxicity, and maintains a stable viscosity over a wide temperature range. It also has good oxidation resistance and shear resistance. Mineral oil is refined from petroleum, is relatively low-cost, provides a certain degree of lubricity, and has appropriate viscosity. It is commonly used in shock absorption or buffer systems in general industrial equipment.

[0049] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, the separation device for petrochemical production also includes a material receiving and flushing component and a base 14, the material receiving and flushing component includes a first material receiving box 13 and a second material receiving box 16 fixed on the base 14, the first material receiving box 13 is used to receive the suspended solids extruded from the extrusion port 6, and the second material receiving box 16 is used to receive the wastewater filtered out of the outer net tube 36 and discharged from the end of the end branch pipe 28; a filter plate 35 is obliquely installed on the inner side of the second material receiving box 16, a lifting pump 34 is fixed to the lower side of the filter plate 35, and a flushing pipe 18 is installed at the outlet of the lifting pump 34, and the other end of the flushing pipe 18 is connected to the liquid guide pipe 23 through a flexible pipe 22, and the liquid guide pipe 23 is connected to the inner The mesh tube 31 is coaxially arranged, and the other end of the liquid guide tube 23 is rotatably connected to the end support shaft 33. The end of the liquid guide tube 23 away from the end support shaft 33 is also fixedly installed with a front fixing frame 21, and the front fixing frame 21 is also fixedly connected to the front end base 2, so as to achieve stable support for the liquid guide tube 23. The area between the outer side of the inner mesh tube 31 and the inner side of the outer mesh tube 36 on the liquid guide tube 23 is also installed with multiple nozzles 32; the liquid guide tube 23 is also slidably provided with a closing head 29 that can seal the end of the end branch tube 28, and a flushing control push-pull cylinder 27 is also fixed on the front end base 2, and the telescopic core shaft end of the flushing control push-pull cylinder 27 is fixed with a driving frame 26, and the driving frame 26 is also fixedly connected to the closing head 29. When flushing is required, the flushing control push-pull cylinder 27 controls the closing head 29 to seal the end of the end branch pipe 28, thereby starting the lifting pump 34 to lift the water and transport it to the flushing pipe 18, and then transport it to the liquid guide pipe 23 through the flexible tube 22, and finally discharged through the nozzle 32. As the inner mesh tube 31 and the outer mesh tube 36 continue to rotate, the water flows out through the inner mesh tube 31 and the outer mesh tube 36, thereby achieving the purpose of flushing the inner mesh tube 31 and the outer mesh tube 36.

[0050] Preferably, the filter plates 35 comprise, from top to bottom, a gravel layer (providing preliminary mechanical filtration and preventing subsequent clogging of finer filter media), a coarse sand layer (further capturing medium-sized suspended particles), a fine sand layer (further filtering smaller particles), an activated carbon layer (adsorbing organic compounds, dissolved oils, and certain heavy metal ions, while also improving the color and odor of the water), and a support layer (supporting all filter media above and ensuring even water flow distribution, typically a perforated plate). This further treats the wastewater and ensures subsequent refined treatment and flushing. The sidewalls of the second receiving box 16 are also provided with a drain port 15. This includes a sewage outlet connected to the bottom of the upper space of the tilted filter plate 35 and a liquid outlet connected to the bottom of the lower space of the filter plate 35, facilitating the discharge of dirt from the filter plate 35 and treated wastewater.

[0051] Preferably, the flushing pipe 18 is also fixedly connected to the outer wall of the second material receiving box 16 through a support rod 19 to ensure the stability of the flushing pipe 18; the side of the closing head 29 close to the end of the end branch pipe 28 is conical in shape, which can reliably seal the end of the end branch pipe 28.

[0052] Preferably, the inner net tube 31 and the outer net tube 36 are both cylindrical cylinder structures, and the pore size of the inner net tube 31 and the outer net tube 36 is the same, and the pore size of the inner net tube 31 and the outer net tube 36 is 30-70 μm; the outer side of the outer net tube 36 is also sleeved with a guide sleeve 3, one end of the guide sleeve 3 is fixedly connected to the rear end base 4, and the other end of the guide sleeve 3 is fixed with an open ring 24, the inner ring of the open ring 24 is fixedly connected to the outer wall of the outer net tube 36, and the lower part of the open ring 24 is provided with a discharge outlet 25 corresponding to the second material receiving box 16; in order to improve the stability of the guide sleeve 3, the end of the guide sleeve 3 is also fixedly connected to the front end base 2 through a circumferentially distributed reinforcement brace 20. Through the setting of the guide sleeve 3 and the open ring 24, the wastewater filtered out of the outer net tube 36 can reliably flow into the inner side of the second material receiving box 16 through the discharge outlet 25.

[0053] like Figure 1 As shown, as a preferred embodiment of the present invention, the separation device for petrochemical production further includes a support angle adjustment assembly, which is used to control and adjust the inclination angle of the outer net tube 36; the support angle adjustment assembly includes a support 17 and an inclination adjustment push-pull cylinder 12, which are respectively hinged to the underside of the front base 2 and the rear base 4. The lower end of the support 17 is fixed to the inner bottom of the second material receiving box 16, and the support 17 passes through the filter plate 35 and is fixedly connected thereto. The lower end of the inclination adjustment push-pull cylinder 12 is hinged to the inner bottom of the first material receiving box 13. By controlling the extension and contraction of the inclination adjustment push-pull cylinder 12, the inclination angle of the outer net tube 36 can be adjusted, resulting in a better coordination effect with the spiral blade 30, thereby improving the effect and efficiency of wastewater treatment.

[0054] The above-described embodiments of the present invention provide a separation device for petrochemical production. Compared to conventional sedimentation and centrifugal separation methods, the present invention further improves separation efficiency (suspended solids), reaching approximately 96% to 98% (inclination angle of outer screen 36: 10° to 25°; drive speed of end support shaft 33: 120 rpm to 200 rpm; sealing force on extrusion port 6: 0.05 MPa to 0.15 MPa; turbidity of treated wastewater: <10 NTU). Furthermore, the device occupies a small footprint and has a long maintenance cycle (self-cleaning function). The operating principle is as follows:

[0055] Wastewater containing suspended solids generated by the petrochemical industry is transported to the front base 2 through the input pipe 1 and enters the chamber 40 inside the front base 2. The chamber 40 evenly distributes the wastewater to the area between the outer side of the inner mesh cylinder 31 and the inner side of the outer mesh cylinder 36 through multiple inlet holes 38 distributed circumferentially.

[0056] The drive assembly (including the drive motor 10 and the reducer 9) drives the end support shaft 33 to rotate, causing the inner mesh cylinder 31 and the spiral blades 30 to rotate synchronously. During rotation, the spiral blades 30 push the liquid away from the front base 2, simultaneously separating the suspended solids in the wastewater from the liquid and pushing the solids toward the rear base 4.

[0057] The support angle adjustment assembly can adjust the inclination angle of the outer net tube 36 to optimize the working efficiency of the spiral blade 30 and improve the separation effect.

[0058] As the suspended solids move backward, when they reach the vicinity of the extrusion port 6 and the pressure exceeds the blocking force of the elastic blocking assembly 7 , the suspended solids are squeezed out of the extrusion port 6 and collected by the first receiving box 13 .

[0059] The filtered liquid flows through the inner and outer mesh cylinders 31, 36, and enters the second receiving box 16. The filter plates 35 further purify the liquid. The purified water is pumped by the lift pump 34 and transported through the flushing pipe 18 and flexible pipe 22 to the liquid guide pipe 23. The water then flows through the nozzle 32 to clean the inner and outer mesh cylinders 31, 36, ensuring continued efficient operation of the equipment.

[0060] In order to keep the equipment clean, the end of the end branch pipe 28 can be temporarily blocked by the closing head 29, and the water flow provided by the lifting pump 34 is used to flush the inside of the inner mesh tube 31 and the outer mesh tube 36 through the nozzle 32 to improve the flushing effect.
