[0002] Animal and vegetable oil wastewater is the wastewater with animal and vegetable oil produced in the waste material treatment process of animal and vegetable oil production, which is mainly the animal and vegetable oil produced by the equipment after stopping, and the washing water is washed out with animal and vegetable oil, because the animal and vegetable oil still has a lot of broken materials, this part of broken materials is not fully squeezed during the production of animal and vegetable oil, so it has great recycling value, such as animal feed, etc., so the treatment of animal and vegetable oil wastewater needs to separate the broken materials in the animal and vegetable oil, and the separation process is relatively simple, the prior art separates the animal and vegetable wastewater through the bucket-shaped filter screen in the tank, the animal and vegetable oil and wastewater pass through the filter screen, and the broken materials are intercepted and retained in the filter screen, and the bottom of the bucket-shaped filter screen is opened every interval to discharge the broken materials. However, because the animal and vegetable oil wastewater is different from ordinary wastewater, the animal and vegetable oil is mixed in the wastewater, the animal and vegetable oil is relatively viscous, and part of the broken materials is mixed in the animal and vegetable oil, so that the viscous animal and vegetable oil is easily attached to the bucket-shaped filter screen when the animal and vegetable oil wastewater passes through the bucket-shaped filter screen, although the animal and vegetable oil falls under the action of its own gravity when the bucket-shaped filter screen discharges the broken materials, but the flow is slow, which affects the discharge efficiency of the bucket-shaped filter screen, and the animal and vegetable oil attached to the bucket-shaped filter screen is not easy to fall, which increases the probability of filter screen blockage, affects the next use of filter screen or increases the cleaning frequency of filter screen.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please refer to Figures 1-6 This application provides a wastewater treatment device for animal and vegetable oils, including a tank 1. A partition 2 is installed inside the tank 1, and a funnel-shaped filter 3 is fixedly connected to the upper part of the partition 2. After the animal and vegetable oil wastewater enters the funnel-shaped filter 3, the debris in the wastewater is intercepted within the funnel-shaped filter 3, while the wastewater and animal and vegetable oils pass through the funnel-shaped filter 3 into a discharge chamber 5 and are discharged through a discharge pipe 7. Both the partition 2 and the funnel-shaped filter 3 are fixedly connected to the inner wall of the tank 1. A discharge pipe 4 is installed through the bottom of the partition 2 and is connected to the bottom of the funnel-shaped filter 3. The partition 2 divides the interior of the tank 1 into a discharge chamber 5 and a discharge chamber 6. The debris discharged from the funnel-shaped filter 3 falls into the discharge chamber 5. A discharge pipe 7 is fixedly connected to the outer wall of the tank 1 and is connected to the bottom of the discharge chamber 5. An inlet pipe 8 is also fixedly connected to the outer wall of the tank 1 and is connected to the discharge chamber 5. The animal and vegetable oil wastewater passes through the inlet pipe 8. The material enters the tank 1 and falls into the funnel-shaped filter screen 3. An electric valve 9 is connected to the feed pipe 8. A PLC controller 10 is fixedly connected to the outer wall of the tank 1. A motor 11 is fixedly connected to the upper part of the tank 1. The electric valve 9 and the PLC controller 10 are electrically connected. The motor 11 has a self-locking function. When the motor 11 is turned off, the output end of the motor 11 is no longer subject to external force. The self-locking function of the motor 11 is existing technology and will not be described in detail. A processing mechanism is set on the upper side of the funnel-shaped filter screen 3. One end of the processing mechanism is connected to the output end of the motor 11. The upper part of the processing mechanism is fixedly connected to the upper part of the tank 1. One end of the processing mechanism is movably sealed in the discharge pipe 4. When the processing mechanism can open the bottom of the discharge pipe 4, it will impact the funnel-shaped filter screen 3, so that the animal and vegetable oils attached to the funnel-shaped filter screen 3 and the fragments mixed with the animal and vegetable oils can fall off the funnel-shaped filter screen 3 more quickly and easily.

[0021] The processing mechanism includes a drive unit. One end of the drive unit is connected to the output end of the motor 11, and the other end is connected to the upper part of the tank 1. Several impact members are fixedly connected to the drive unit along the circumferential direction. The drive unit drives the impact members and the opening and closing members to move up and down. The impact members are located on the upper side of the bucket-shaped filter screen 3. The bottom of the drive unit is fixedly connected to the opening and closing members, and the opening and closing members are movably sealed in the discharge pipe 4.

[0022] The driving component includes a frame 12, with a lifting rod 13 movably connected through the frame 12. A first spring 14 and a circular base plate 15 are provided inside the frame 12. The first spring 14 is sleeved on the lifting rod 13, and the center of the circular base plate 15 is fixed to the lifting rod 13. The bottom of the first spring 14 is fixed to the upper part of the circular base plate 15, and the upper part of the first spring 14 is fixed to the upper part of the frame 12. When the lifting rod 13 rises, it drives the circular base plate 15 to rise together. The circular limiting plate 15 presses the first spring 14, compressing the first spring 14. An impact member is fixed on the lifting rod 13, and an opening and closing member is fixed to the bottom of the lifting rod 13. The lifting rod 13 drives the impact member and the opening and closing member to rise and fall. A driving assembly is fixedly connected to the upper part of the frame 12. A concave opening 16 is opened at the upper end of the lifting rod 13, and one end of the driving assembly is rotatably connected to the concave opening 16.

[0023] The drive assembly includes a vertical plate 17 fixed to the frame 12. The upper part of the vertical plate 17 is fixed to the upper part of the tank 1. The vertical plate 17 is located behind the lifting rod 13. A first bearing 18 is embedded in the vertical plate 17. A rotating shaft 19 is fixedly connected to the first bearing 18. One end of the rotating shaft 19 is fixedly connected to the output end of the motor 11. The motor 11 drives the rotating shaft 19 to rotate within the first bearing 18. A fixing ring 20 and a second bearing 21 are fixedly connected to the rotating shaft 19 from back to front. The rotating shaft 19 drives the fixing ring 20 and the lever 22 to rotate. The lever 22 is connected to the fixing ring 20. The rotating shaft 19 is fixedly connected to the inner ring of the second bearing 21. A crank 23 is fixedly connected to the outer ring of the second bearing 21. Due to the crank 23 and the connecting rod 24 The connecting rod 24 and the lifting rod 13 are rotatably connected. The lifting rod 13 is restricted by the downward elastic force of the first spring 14. Therefore, when the lever 22 does not move the lever shaft 25, the rotating shaft 19 only drives the inner ring of the second bearing 21 to rotate. The outer ring of the second rotating shaft 21 and the crank 23 fixed on the outer ring do not rotate. The crank 23 is rotatably connected to the connecting rod 24 through the pin. The initial position of the connecting rod 24 points to the 11 o'clock position. When it is at the 11 o'clock position, the fixed ring 20 drives the lever 22 to rotate, and the lever shaft 25 is lifted by the lever 22. The lever shaft 25 is located on the upper part of the lever 22. The connecting rod 24 is rotatably connected to the concave opening 16 through the pin. The connecting rod 24 rotates in the concave opening 16. The lever shaft 25 is fixedly connected to the back of the crank 23.

[0024] The impact component includes an L-shaped connecting rod 26 fixed to the lifting rod 13. The L-shaped connecting rod 26 rises and falls with the lifting rod 13. A sleeve 27 is fixedly connected to the bottom of the L-shaped connecting rod 26. The L-shaped connecting rod 26 drives the sleeve 27 to rise and fall. A circular limiting plate 28 is movably connected inside the sleeve 27. The circular limiting plate 28 is attached to the inner wall of the sleeve 27 and slidably connected to the sleeve 27. An impact rod 29 is fixedly connected to the circular limiting plate 28. The impact rod 29 moves through the bottom of the sleeve 27 and has an impact ball 30 fixedly connected to its end. The impact ball 30 is located on the upper side of the funnel-shaped filter screen 3. A second spring 31 is sleeved on the impact rod 29. The upper end of the second spring 31 is fixed to the bottom of the circular limiting plate 28, and the lower end is fixed to the bottom of the sleeve 27. When the impact ball 30 impacts the funnel-shaped filter screen 3, the impact ball 30 drives the impact rod 29 and the circular limiting plate 28 to move upward. The circular limiting plate 28 drives the second spring 31 to stretch.

[0025] The opening and closing mechanism includes a lifting rod 32 fixed to the bottom of the lifting rod 13. The lifting rod 32 extends into the discharge pipe 4. A cone 33 with its tip pointing upward is fixedly connected to the bottom of the lifting rod 32. A cylinder 34 is connected to the bottom of the cone 33. The diameters of both the cylinder 34 and the cone 33 are the same as the diameter of the discharge pipe 4. The cone 33 is fixed to the upper part of the cylinder 34 and forms an integral part with the cylinder 34. The cone 33 and the cylinder 34 rise and fall with the lifting rod 32. The cone 33 and the cylinder 34 form a movable seal with the discharge pipe 4, which serves to open and close the discharge pipe 4. Initially, the cone 33 is located inside the discharge pipe 4, and the upper part of the cylinder 34 is initially located inside the discharge pipe 4 and forms a movable seal with the discharge pipe 4.

[0026] The tank body 1 is equipped with support legs 35 at the bottom to support and elevate the tank body 1. A screw conveyor 36 is installed on the lower side of the tank body 1, and the upper part of the screw conveyor 36 is connected to the bottom of the tank body 1. The crushed material discharged from the tank body 1 falls into the screw conveyor 36 and is pushed out by the screw conveyor 36.

[0027] Working principle of the invention:

[0028] Please refer to Figure 4 and 5 Initially, the connecting rod is located at the 11 o'clock position, the lever 22 is located below the lever shaft 25, the lifting rod 13 and the circular base plate 15 are lifted slightly, the first spring 14 is compressed, the impact ball 30 is located on the upper side of the bucket-shaped filter screen 3, the cone 33 is located inside the discharge pipe 4, the upper part of the cylinder 34 is located inside the discharge pipe 4, and the cone 33 and the cylinder 34 close the discharge pipe 4.

[0029] Every so often, when the bucket-shaped filter screen 3 needs to discharge the debris inside, the PLC controller 10 controls the electric valve 9 to close, stopping the flow of animal and vegetable oil wastewater into the tank 1. Simultaneously, the motor 11 starts, driving the rotating shaft 19 to rotate clockwise. The rotating shaft 19 drives the fixed ring 20 and the lever 22 to rotate. The lever 22's rotation drives the lever shaft 25 to rotate, which in turn drives the crank 23 to rotate. Since the rotating shaft 19 drives the inner ring of the second bearing 21 to rotate, and the crank 19 drives the outer ring of the second bearing 21 to rotate, the crank 19, the second bearing 21, and the rotating shaft 19 are essentially a solid assembly relative to each other. The crank 19 drives the connecting rod 24 to rotate, which rotates within the concave opening 16 and causes the lifting rod 24 and the circular base plate 15 to rise. The first spring 1... 4 continues to be compressed, and the lifting rod 13 drives the impact member and the opening and closing member to continue to rise. At this time, the conical body 33 and the cylindrical body 34 also rise in the discharge pipe 4. The discharge pipe 4 is still in the closed state. When the connecting rod 24 rotates to the top (12 o'clock position), the lifting rod 13 rises to the highest position. Immediately afterwards, when the lever 22 rotates to the highest position, the lever shaft 25 and the crank 23 are both located to the right of the lever 22. Affected by the rebound force of the first spring 14, the lifting rod 13 and the circular base plate 15 generate a strong downward potential energy. The lifting rod 13 drives the connecting rod 24 to pull down rapidly. The connecting rod 24 drives the crank 23 to pull down. The crank 23 drives the lever shaft 25 to rotate quickly clockwise (the motor 11 drives the rotating shaft 19, the fixed ring 20, and the lever 22 to rotate normally at a slow and uniform speed, so at this time...). When the crank 23 rotates in front of the lever 22, the lifting rod 13 descends rapidly, causing the lifting rod 32, the conical body 33, and the cylindrical body 34 to descend (the diameter of the lifting rod 32 is much smaller than the diameter of the discharge pipe 3), until one end of the crank 23 rotates to the 6 o'clock position. At this time, the crank 23, the connecting rod 24, and the lifting rod 13 are in a vertical state. The motor 11 is turned off, and the conical body 33 and the cylindrical body 34 both descend to the lower side of the discharge port 4. The discharge port 4 opens. At the same time as it opens, the lifting rod 13 causes the L-shaped connecting rod 26 and the sleeve 27 to descend. The impact ball 30 strikes the bucket-shaped filter screen 3. The impact ball 30 causes the impact rod 29 to move upward. The impact rod 29 causes the circular limiting plate 28 to move upward inside the cylinder. The circular limiting plate 28 causes the second spring 31 to stretch. When the funnel-shaped filter screen 3 is impacted by the impact ball 30, the animal and vegetable oils adhering to the inner wall of the funnel-shaped filter screen 3, along with the debris mixed in with the animal and vegetable oils, fall rapidly along with the debris inside the funnel-shaped filter screen 3. The debris is discharged through the discharge pipe 4, and then falls onto the upper part of the cone-shaped body 33 on the lower side of the discharge pipe 4, dispersing to both sides and flowing down into the discharge bin 6. After a period of time, the PLC controller 10 controls the motor 11 to open again, and the rotating shaft 19 continues to drive the fixed ring 20 and the lever 22 to rotate clockwise. When the lever 22 contacts the lever shaft 25 again, it drives the lever shaft 25 to rotate. Then the crank 23 also rotates, the lifting rod 13 rises again, the impact ball 30 rises to the upper side of the funnel-shaped filter screen 3, and the cone-shaped body 33 and the cylinder 34 re-enter the discharge pipe 4, causing the discharge pipe 4 to close.Until link 24 rotates back to the 11 o'clock position, motor 11 shuts off and locks itself (to prevent being pulled down counterclockwise by lifting rod 13).

[0030] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
