Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a high-efficiency treatment device for recycling waste vegetable oil wastewater. Background Art

[0002] In the vegetable oil production process, in the vegetable oil extraction link, such as after producing vegetable oil by pressing or leaching, water is needed to clean the equipment. Since the equipment contains residual waste vegetable oil, waste vegetable oil wastewater is generated after the equipment is cleaned. Since the waste vegetable oil wastewater contains sediment, the waste vegetable oil wastewater needs to be treated when it is recycled to separate the sediment in the waste vegetable oil from the wastewater. The prior art intercepts the sediment in the waste vegetable oil wastewater through a filtering device to separate the sediment in the waste vegetable oil wastewater, and then stops treating the waste vegetable oil wastewater at regular intervals to clean out the sediment in the filtering device. However, the prior art can only achieve the separation treatment of oil and water from sediment in the waste vegetable oil wastewater. In addition to sediment, the waste vegetable oil oil water also contains residual waste vegetable oil and washing water. Since the waste vegetable oil has a high recovery value, the prior art cannot simultaneously treat and separate the waste vegetable oil, washing water and sediment, resulting in certain economic losses.

[0017] Please refer to Figure 6-7The separation component includes a cleaning water separation cylinder 24 arranged on the push rod 21. The upper and lower parts of the cleaning water separation cylinder 24 are both open structures. The cleaning water separation cylinder 24 is made of a super-hydrophilic-super-oleophobic stainless steel filter mesh rolled and welded. The super-hydrophilic-super-oleophobic stainless steel filter mesh has a strong affinity for water, and water can quickly spread and penetrate on its surface, while it has a strong repulsion to oil, so that oil cannot pass through. The waste vegetable oil wastewater first enters the cleaning water separation cylinder 24 through the conveying pipeline 1. The cleaning water separation cylinder 24 is used to separate the cleaning water. A waste vegetable oil separation cylinder 25 is arranged at the bottom of the cleaning water separation cylinder 24. The waste vegetable oil separation cylinder 25 is used to separate the waste vegetable oil. The filter hole diameter on the cleaning water separation cylinder 24 is smaller than the filter hole diameter on the waste vegetable oil separation cylinder 25. The waste vegetable oil separation cylinder 25 is made of ordinary stainless steel filter mesh rolled and welded, so the waste vegetable oil can be directly discharged through the filter holes of the waste vegetable oil separation cylinder 25. The upper part of the waste vegetable oil separation cylinder 25 is an open structure and the bottom is a closed structure. A sealing plate 26 is movably arranged at the bottom of the cleaning water separation cylinder 24, and a spring column 27 is arranged on the upper side of the sealing plate 26. The sealing plate 26 is moved up and down between the bottom of the cleaning separation cylinder 24 and the inside of the waste vegetable oil separation cylinder 25 by the expansion and contraction of the spring column 27. The sealing plate 26 seals the bottom of the cleaning water separation cylinder 24. The lower expansion end of the spring column 27 is connected to the sealing plate 26, and the upper expansion end of the spring column 27 is provided with a triangle 28. The inner wall of the cleaning water separation cylinder 24 is provided with a connecting rod 29, and the connecting rod 29 is fixed to the spring column 27.

[0018] The working principle of the present invention is as follows: waste vegetable oil wastewater enters the cleaning water separation cylinder 24 through the conveying pipeline 1, and the cleaning water, waste vegetable oil and sediment in the waste vegetable oil wastewater remain in the cleaning water separation cylinder 24, wherein the cleaning water falls into the cleaning water collection pool 2 through the cleaning water separation cylinder 24, while the waste vegetable oil and sediment cannot pass through the cleaning water separation cylinder 24 and remain in the cleaning water separation cylinder 24. At regular intervals, the conveying pipeline 1 is closed to stop conveying the waste vegetable oil wastewater, and at the same time, the motor 9 is started, and the motor drives the first connecting rod 10 to rotate slowly, and the first connecting rod 10 drives the second connecting rod 11, and the second connecting rod 11 rotates while driving the slide plate 17 to move slowly to the right in the guide rail 12, and the slide plate 17 drives the vertical plate 19 and the push rod 21 to move to the right, and the push rod 21 drives the entire The separation assembly moves to the right, and the push rod 21 also drives the limiting rod 23 to move horizontally to the right in the slide groove 14. When the separation assembly moves to the top of the waste vegetable oil collection pool 3, the right inclined surface of the triangular body 28 slides and contacts with the oblique section of the left end of the beam 6. Limited by the beam 6, the triangular body 28 moves downward, and at the same time, the triangular body 28 drives the upper telescopic end of the spring column 27 to descend, and the upper telescopic end of the spring column 27 drives the lower telescopic end of the spring column 27 to descend, and the lower telescopic end of the spring column 27 drives the sealing plate 26 to descend, so that the sealing plate 26 descends to the inside of the waste vegetable oil separation cylinder 25, until the top end of the triangular body 28 slides and contacts with the bottom of the beam 6, the triangular body 28 stops descending and continues to move to the right driven by the push rod 21, cleaning the waste vegetable oil in the water separation cylinder 24. The waste vegetable oil and sediment settle into the waste vegetable oil separation cylinder 25 as the sealing plate 26 settles. The waste vegetable oil in the waste vegetable oil separation cylinder 25 falls into the waste vegetable oil collection pool 3 through the filter holes on the waste vegetable oil separation cylinder 25, while the sediment is intercepted and retained in the waste vegetable oil separation cylinder 25. When the triangle 28 separates from the crossbeam 6, the spring column 27 rebounds, and the lower telescopic end of the spring column 27 drives the sealing plate 26 to rise. The sealing plate 26 drives the sediment on its upper part to be lifted together, and the sediment returns to the cleaning water separation cylinder 24. When the limiting rod 23 just reaches the position of the spiral groove 16 from the slide groove 14, the entire separation assembly just reaches the top of the sediment collection pool 4. When the limiting rod 23 enters the spiral groove 16, it is limited by the semicircular trajectory of the entire spiral groove 16. The rod 23 moves to the right while rotating a semicircle in the spiral groove 16, the limiting rod 23 drives the fixed sleeve 22, and the fixed sleeve 22 drives the push rod 21 to rotate 180 degrees in the bearing 20, so that the cleaning water separation cylinder 24 and the waste vegetable oil separation cylinder 25 are turned over 180 degrees, and the sediment in the cleaning water separation cylinder 24 is dumped into the sediment collection pool 4. At this time, the motor 9 drives the first connecting rod 10 to rotate exactly a semicircle. When the motor 9 drives the first connecting rod 10 to rotate the remaining semicircle, the limiting rod 23 returns to the original path in the spiral groove 16, the cleaning water separation cylinder 24 and the waste vegetable oil separation cylinder 25 rotate back to the right, and then return to the original path to the right driven by the push rod 21. When the motor 9 drives the first connecting rod 10 to rotate a full circle, the entire separation assembly just returns to the initial position.Then the delivery pipeline 1 is opened to continue delivering the waste vegetable oil wastewater to the washing water separation cylinder 24.

[0019] The present invention is simple to operate, convenient to use, and suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
