[0020] 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.
[0021] See also Figures 1-8 The figure shows a sewage treatment device for oil drilling, which includes a device shell 1, a feed port 2 is provided above the device shell 1, a partition 4 is fixedly inserted inside the device shell 1, a water outlet 3 is provided on the outer surface of the device shell 1, the water outlet 3 is located below the partition 4, a mixing mechanism is provided above the partition 4, a pusher 16 is provided below the partition 4, the pusher 16 is connected to the device shell 1 through a lifting mechanism, a collecting assembly is provided below the water outlet 3, a discharge port 35 is provided below the outer surface of the device shell 1, the pusher 16 is designed in a truncated cone shape, a filter hole 20 is opened and closed at the center of the pusher 16, a blocking member 21 is provided below the pusher 16, and the blocking member 21 is connected to the pusher 16 through a limiting mechanism, a discharge port 5 is provided inside the partition 4, and an opening and closing mechanism is provided outside the discharge port 5.
[0022] Specifically, wastewater and coagulant are put into the interior of the device shell 1 from the feed port 2. With the cooperation of the opening and closing mechanism, the discharge port 5 is in a closed state at this time, and the wastewater is located above the partition 4. The stirring mechanism drives the wastewater and coagulant to stir, so that the wastewater can fully contact the coagulant, which is convenient for gathering the suspended matter in the wastewater into large particles. At the same time, the lifting mechanism drives the pusher 16 to move upward, and the pusher 16 moves to the bottom of the partition 4 and stops. Under the action of the limiting mechanism, the blocking member 21 is separated from the pusher 16. After the wastewater and the coagulant are mixed, the opening and closing mechanism allows the discharge port 5 to be in an open state. At this time, the wastewater above the partition 4 can enter the bottom of the device shell 1 through the discharge port 5. When the wastewater passes through the pusher 16, the filter hole 20 can filter the larger particles in the wastewater, and the collecting mechanism can collect the larger particles. The wastewater passes through the filter with smaller particles. The filter 20 flows along the surface of the blocking member 21 to the bottom of the device housing 1, and the lifting mechanism drives the pushing member 16 and the blocking member 21 to move downward. When the pushing member 16 and the blocking member 21 move to the bottom of the device housing 1, under the action of the limiting mechanism, the pushing member 16 and the blocking member 21 are fixed together. At this time, the blocking member 21 can block the filter hole 20. When the wastewater and the coagulant are mixed above the partition 4, the mixed wastewater can be allowed to stand below the partition 4. After standing, the lifting mechanism drives the pushing member 16 and the blocking member 21 to move upward again. The pushing member 16 drives the wastewater above to move upward synchronously, and the wastewater is discharged through the water outlet 3. The particles and impurities can stay above the pushing member 16. When the pushing member 16 and the blocking member 21 are separated, the impurities and particles can pass through the filter hole 20 and fall to the bottom of the device housing 1 and be discharged through the discharge port 35.
[0023] The mixing mechanism includes a rotatable shaft 14 , which is rotatably inserted into the interior of the device housing 1 . The shaft 14 is vertically arranged, and a stirring blade 13 is fixedly installed on the outer surface of the shaft 14 . The stirring blade 13 is located above the partition 4 .
[0024] A motor 15 is fixedly mounted below the device housing 1 . The output end of the motor 15 passes through the device housing 1 and extends into the interior of the device housing 1 . The output end of the motor 15 is fixedly connected to the lower end of the rotating shaft 14 .
[0025] Specifically, the motor 15 is connected to an external power source, and the motor 15 drives the rotating shaft 14 to rotate. When the rotating shaft 14 rotates, it can drive the stirring blade 13 to rotate, so as to increase the contact area between the wastewater and the coagulant and improve the mixing efficiency.
[0026] The lifting mechanism includes a thread groove 19, which is opened on the outer surface of the rotating shaft 14. The thread groove 19 is threadedly connected to the pusher 16. A slider 18 is fixedly installed on the outer surface of the pusher 16. A slide groove 17 is opened inside the device housing 1, and the slide groove 17 and the slider 18 are slidably connected.
[0027] When the rotating shaft 14 rotates, it drives the thread groove 19 to rotate. Since the thread groove 19 and the pushing member 16 are threadedly connected, the rotating shaft 14 can drive the pushing member 16 to rise and fall through the thread groove 19 when it rotates. When the pushing member 16 moves, it drives the slider 18 to move inside the slide groove 17, which is beneficial to increase the stability of the pushing member 16 when it moves.
[0028] The collecting assembly includes a trough body 29, which is fixedly mounted on the outer surface of the device housing 1. The trough body 29 is communicated with the device housing 1. A discharge port 30 is provided below the trough body 29. The trough body 29 is located below the water outlet 3. A guide groove 34 is provided inside the device housing 1. The guide groove 34 is located above the slide 17 and is communicated with the slide 17. A guide block 33 is slidably inserted inside the guide groove 34. The guide block 33 is in contact with the slider 18. A counterweight block 32 is fixedly mounted above the guide block 33. An adjusting member 31 is fixedly mounted on the side of the counterweight block 32 away from the device housing 1. The adjusting member 31 is in contact with the trough body 29 and the water outlet 3.
[0029] In the initial state, the adjusting member 31 contacts the trough body 29, and the adjusting member 31 blocks the connection between the trough body 29 and the device housing 1, so that when separating the wastewater and impurities, the wastewater can only be discharged from the water outlet 3. When the pushing member 16 moves to the bottom of the partition 4, the pushing member 16 drives the guide block 33 to move upward through the slider 18, and the guide block 33 drives the counterweight block 32 and the adjusting member 31 to move synchronously. At this time, the adjusting member 31 is separated from the trough body 29, and the adjusting member 31 contacts the water outlet 3. The adjusting member 31 blocks the water outlet 3. When the mixed wastewater passes through the pushing member 16, the large particles blocked on the upper surface of the pushing member 16 can fall along the upper surface of the pushing member 16 into the interior of the trough body 29 and be discharged through the discharge port 30.
[0030] The limiting mechanism includes a support rod 22 and a fixed plate 28. The support rod 22 is fixedly installed below the push member 16. The support rod 22 and the blocking member 21 are slidably connected. The blocking member 21 is connected to the push member 16 through a fixed assembly. The fixed plate 28 is fixedly installed inside the device housing 1. The fixed plate 28 is located below the blocking member 21, and the fixed plate 28 and the blocking member 21 are in contact and fit.
[0031] The fixing assembly includes a limit block 23 and a limit hole 24. The limit block 23 is fixedly installed above the blocking member 21. The limit hole 24 is opened at the center of the pushing member 16. The limit block 23 and the limit hole 24 are plug-fitted together, and a stable structure is installed inside the limit block 23.
[0032] The stabilizing structure includes a groove 25, which is opened inside the limit block 23. A protrusion 26 is slidably installed inside the groove 25. The protrusion 26 is in contact with the upper surface of the push member 16. A No. 2 spring 27 is installed between the protrusion 26 and the groove 25. The upper surface end face of the protrusion 26 away from the limit block 23 is in an arc shape.
[0033] In the initial state, the blocking member 21 and the pushing member 16 are in contact with each other. At this time, the limit block 23 passes through the limit hole 24. Under the action of the groove 25 and the No. 2 spring 27, the protrusion 26 is located above the pushing member 16. The lifting mechanism drives the pushing member 16 to move upward. During the movement, the cross plate 10 contacts the protrusion 26, and the cross plate 10 pushes the protrusion 26 into the interior of the groove 25. Under the action of gravity, the blocking member 21 slides downward on the outer surface of the support rod 22, so that the blocking member 21 and the pushing member 16 are separated.
[0034] When the pushing member 16 and the blocking member 21 move downward, the blocking member 21 contacts the fixed plate 28, and the pushing member 16 continues to move toward the blocking member 21, so that the limit block 23 can pass through the limit hole 24. Under the action of the No. 2 spring 27, the protrusion 26 can be moved out from the inside of the groove 25, so that the blocking member 21 can fit with the pushing member 16.
[0035] The opening and closing mechanism includes a baffle 6, which is arranged below the partition 4. The area of the baffle 6 is larger than the area of the discharge port 5. Fixed blocks 8 are fixedly installed on both sides of the baffle 6. A slide rod 7 slides through the interior of the fixed block 8. The slide rod 7 is fixedly connected to the partition 4. A spring No. 1 movably sleeve is provided on the outer surface of the slide rod 7. The spring No. 12 is fixedly connected to the fixed block 8. One side of the baffle 6 is connected to the protrusion 26 through a pushing assembly.
[0036] The pushing assembly includes a transverse plate 10, which is arranged between the partition 4 and the pushing member 16. The transverse plate 10 is in contact with the protrusion 26. A column 11 is fixedly installed above the transverse plate 10. The column 11 is slidingly connected to the partition 4. A push plate 9 is rotatably installed above the transverse plate 10. The end of the push plate 9 away from the transverse plate 10 is rotatably connected to the baffle 6.
[0037] Specifically, under the action of the column 11, the pushing member 16 contacts the horizontal plate 10 when moving upward and drives the horizontal plate 10 to move upward. The horizontal plate 10 drives the push plate 9 to rotate, and the push plate 9 pushes the baffle 6 and the fixed block 8 to move on the outer surface of the slide rod 7 in the direction away from the rotating shaft 14. At this time, the No. 1 spring 12 is deformed by the force, the baffle 6 is separated from the discharge port 5, and the discharge port 5 is in an open state.
[0038] Working principle: wastewater and coagulant are put into the interior of the device shell 1 from the feed port 2. With the cooperation of the opening and closing mechanism, the discharge port 5 is in a closed state at this time, and the wastewater is located above the partition 4. The motor 15 is connected to the external power supply. The motor 15 drives the rotating shaft 14 to rotate. When the rotating shaft 14 rotates, it can drive the stirring blade 13 to rotate, so that the wastewater can fully contact with the coagulant, which is convenient for aggregating the suspended matter in the wastewater into large particles.
[0039] At the same time, the rotating shaft 14 drives the thread groove 19 to rotate when it rotates. Since the thread groove 19 and the pushing member 16 are threadedly connected, the rotating shaft 14 can drive the pushing member 16 to rise and fall through the thread groove 19 when it rotates. When the pushing member 16 moves, it drives the slider 18 to move inside the slide groove 17. The pushing member 16 moves upward to the bottom of the partition 4 and stops. When moving, the cross plate 10 contacts the protrusion 26, and the cross plate 10 pushes the protrusion 26 into the inside of the groove 25. Under the action of gravity, the blocking member 21 slides downward on the outer surface of the support rod 22, so that the blocking member 21 and the pushing member 16 are separated.
[0040] Under the action of the column 11, the pushing member 16 contacts the horizontal plate 10 when moving upward and drives the horizontal plate 10 to move upward. The horizontal plate 10 drives the push plate 9 to rotate, and the push plate 9 pushes the baffle 6 and the fixed block 8 to move on the outer surface of the slide rod 7 in the direction away from the rotating shaft 14. At this time, the No. 1 spring 12 is deformed by the force, the baffle 6 is separated from the discharge port 5, and the discharge port 5 is in an open state. At this time, the wastewater above the partition 4 can enter the bottom of the device housing 1 through the discharge port 5.
[0041] When the wastewater passes through the pushing member 16, the regulating member 31 blocks the water outlet 3. When the mixed wastewater passes through the pushing member 16, the large particles blocked on the upper surface of the pushing member 16 can fall into the interior of the trough 29 along the upper surface of the pushing member 16 and be discharged through the discharge port 30. The wastewater carries smaller particles through the filter holes 20 and flows along the surface of the blocking member 21 to the bottom of the device housing 1. The lifting mechanism drives the pushing member 16 and the blocking member 21 to move downward. When the pushing member 16 and the blocking member 21 move to the bottom of the device housing 1.
[0042] The mixed wastewater is allowed to stand still. After the standing is completed, when the lifting mechanism drives the pushing member 16 and the blocking member 21 to move upward again, the pushing member 16 drives the wastewater above to move upward synchronously, and the wastewater is discharged through the water outlet 3. The particles and impurities can stay above the pushing member 16. When the pushing member 16 and the blocking member 21 are separated, the impurities and particles can pass through the filter hole 20 and fall to the bottom of the device housing 1 and be discharged through the discharge port 35.
