[0016] Compared with the prior art, the beneficial effects of the present invention are: the sludge treatment oil-water separation and oil discharge device can effectively separate and discharge oil when the oil layer is thin, preventing oil from entering the subsequent treatment system along with water through the pump; and the device can achieve automatic control, automatically adjusting the corresponding discharge rate according to the oil-water ratio in the wastewater to improve treatment efficiency. The specific details are as follows:

[0017] 1. The oil drain tank is equipped with a float ball of a level gauge. The oil drain tank is located between a separation plate and an overflow plate. Both sides of the oil drain tank, separation plate, and overflow plate are fixedly connected to the inner wall of the tank body. The bottom of the separation plate is fixedly connected to the side of the oil drain tank away from the overflow plate. The top of the separation plate is lower than the top of the overflow plate. The top of the overflow plate is located away from the inner wall of the tank body, and the bottom of the overflow plate is fixedly connected to the inner wall of the tank body. The top of the side of the oil drain tank away from the separation plate is fixedly connected to the top of the inner wall of the tank body. The middle of the side wall of the separation plate is fixedly connected to the inlet of the first solenoid valve pipe. The bottom of the oil drain tank is fixedly connected to the second... The inlet of the solenoid valve tube and the inlet of the second one-way valve tube are located on the side of the overflow plate away from the oil drain tank. When the oil-water mixture enters the tank, since the density of oil is less than that of water, and the density of the float ball is between that of oil and water, the level gauge will be able to detect the interface between oil and water. At the same time, the oil drain tank will block the oil on one side of the tank, while the water can overflow through the overflow plate, thereby controlling the liquid level in the oil drain tank. When the second solenoid valve tube draws water from the oil drain tank, the oil in the tank will enter the oil drain tank. When the oil-water interface is lower than the port of the first solenoid valve tube, the oil can be discharged through the first solenoid valve tube.

[0018] 2. The center of the arc plate is on the axis of the drive disk. Trigger blocks are fixedly connected to the inner sides of each end of the arc plate. The side of the arc plate away from the trigger blocks is fixedly mounted on the control disk. The side wall of the drive disk has centrally symmetrically distributed limiting grooves. Inserts are embedded in the sockets at the ends of the limiting grooves. The top of each insert is fixedly connected to the lower end of a force-bearing rod. A pressure spring is fixedly connected between the top of the force-bearing rod and the bottom surface of the inner wall of the cylinder frame. A force-bearing inclined surface is provided at the top of the force-bearing rod, and this inclined surface faces the corresponding trigger block. Symmetrically distributed connecting rods are rotatably connected to the side of the cylinder frame away from the drive disk. The drive plate has an oil drain plug and a drain plug on each side. The ends of the oil drain plug and the drain plug are rotatably connected to corresponding connecting rods, which allows the arc plate to adjust the position of the trigger block. When the drive plate drives the cylinder frame to press against the trigger block, the trigger block can push the force rod downward, causing the insert at the bottom of the force rod to disengage from the insertion port at the end of the limiting groove. At this time, the drive plate will not be able to drive the cylinder frame to rotate, allowing the cylinder frame to rotate at the corresponding angle. The cylinder frame will drive the connecting rod to produce a corresponding displacement change, and the discharge ratio of the oil drain plug and the drain plug will change synchronously.

[0039] Two sets of toothed rings 15 and control discs 16 are rotatably mounted on both sides of the inner wall of the loading frame 9. The toothed rings 15 and control discs 16 are rotatably sleeved on the corresponding fixed cylinders 14.

The lower toothed plate 17 and the upper toothed plate 18 will drive the corresponding toothed ring 15 to rotate. The toothed ring 15 will drive the control disk 16, which is fixedly connected, to rotate. Positioning frames 21 are fixedly installed on the top of the inner wall of the loading frame 9 and the upper surface of the bottom plate 8. Arc grooves 12 are opened on different sides of the two positioning frames 21. Corresponding arc plates 22 are rotatably fitted in the arc grooves 12.

[0040] Symmetrically distributed rotating plates 2404 are fixedly installed on the side wall of the cylindrical frame 2405, and the rotating plates 2404 are rotatably embedded in the annular groove at the end of the fixed cylinder 14. The axis of the cylindrical frame 2405 and the axis of the drive disk 2401 are perpendicularly intersected. The side wall of the drive disk 2401 is provided with centrally symmetrically distributed limiting grooves 2403, and the insertion port at the end of the limiting groove 2403 is provided with an insert 2406. The top of the insert 2406 is fixedly connected to the lower end of the force-bearing rod 2408. A reset device is fitted to one side of the cylindrical frame 2405.

Since the lower end of force rod 2408 slides through drive disk 2401 and cylinder frame 2405, and force rod 2408 and cylinder frame 2405 are coaxially arranged, the center of limit groove 2403 is in drive disk On the axis of 2401, a pressure spring 2407 is fixedly connected between the top of the force-bearing rod 2408 and the bottom surface of the inner wall of the cylinder frame 2405.

At this time, the cylinder frame 2405 will drive the force rod 2408 to contact the corresponding trigger block 23. At this time, the force rod 2408 will drive the insert block 2406 to move downward into the limiting groove 2403.

[0041] Working principle: When using this sludge treatment oil-water separation and oil discharge device, first refer to... Figures 1-12 The tank 2 contains an oil mixture. The feeding pipe 3 is used to add the oil mixture. Since oil is less dense than water, the oil will float on the water surface. The density of the float ball 704 is between that of oil and water. At this time, the float ball 704 can display the oil-water interface. When the float ball 704 moves, it will drive the connecting frame 702 to move. The distance sensor 703 can detect the displacement, thereby reflecting the amount of oil in the drain tank 4. Due to the obstruction of the drain tank 4, the oil in the tank 2 will be on the side where the oil separation plate 5 is set. The overflow plate 6 is used to control the liquid level in the tank 2. The water in the tank 2 can pass through the overflow plate 6.

[0042] When the float 704 is above the port of the first solenoid valve tube 28, the distance sensor 703 inside the level gauge 7 detects excessive water in the device. At this time, the device will keep the first solenoid valve tube 28 closed, while the second solenoid valve tube 32 will remain open. Simultaneously, the electric cylinder 20 will drive the moving plate 19 to move. The moving plate 19 will drive the lower toothed plate 17 and the upper toothed plate 18 to move synchronously. The lower toothed plate 17 will drive one toothed ring 15 to rotate clockwise, while the upper toothed plate 18 will drive the other toothed ring 15 to rotate counterclockwise. The two toothed rings 15 will drive the corresponding control disk 16 to rotate, and the control disk 16 will drive the corresponding trigger block through the arc plate 22. The movement of 23 causes a change in the position of the two trigger blocks 23, which will move to the highest point of the corresponding arc groove 12. At the same time, the device will control the servo motor 10 to reciprocate within the set angle range. The servo motor 10 drives the drive disk 2401 to rotate synchronously through the rotating shaft 11. At this time, the drive disk 2401 drives the cylinder frame 2405 to rotate through the insert 2406 and the force rod 2408. Since the two trigger blocks 23 have moved to the highest position, the force rod 2408 in the upper cylinder frame 2405 will be blocked by the trigger blocks 23, and the force rod 2408 in the upper cylinder frame 2405 will move downward until... Unable to move, the insert 2406 at the bottom of the force rod 2408 can enter the limiting groove 2403. The force rod 2408 further compresses the pressure spring 2407, allowing the drive disc 2401 to continue rotating. Meanwhile, the force rod 2408 in the lower cylinder 2405 moves away from the corresponding trigger block 23, allowing the lower cylinder 2405 to rotate to its maximum angle. At this point, the lower cylinder 2405 will drive the drain plug rod 29 to move at its maximum distance via the connecting rod 2409, enabling the drain cylinder 30 to extract the water from the top of the drain tank 4 through the second one-way valve pipe 31 and the second solenoid valve pipe 32. Meanwhile, the drive disc 2401 can drive the cylinder frame 2405 to reset via the reset push block 2402. At this time, the water level in the oil tank 4 will drop. At this time, the level gauge 7 will detect the change in the height of the oil interface. When the oil interface is too low below the first solenoid valve tube 28, it indicates that the oil content in the oil-water mixture in the tank 2 is high. At this time, the electric cylinder 20 will move back a certain distance. As can be seen from the above steps, the movement of the drain plug rod 29 will decrease, while the movement of the oil drain plug rod 25 will increase. At this time, the oil discharge speed of the device will increase accordingly, while the drainage speed will decrease, so that the device can efficiently and continuously discharge oil and water.
