[0021] 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.

[0022] Example: Figures 1-8 As shown, the present invention provides a technical solution: a waste mineral oil regeneration flocculation centrifugal impurity removal device. The waste mineral oil regeneration flocculation centrifugal impurity removal device includes a base 1, a motor 2 mounted on the base 1, a rotating seat 3 rotatably mounted on the base 1, the rotating seat 3 and one output shaft of the motor 2 being connected by a main drive belt 12, a centrifugal seat mounted on the rotating seat 3, a plurality of slag discharge ports 7 evenly opened on the centrifugal seat, an upper shell 5 mounted on the centrifugal seat, an inlet column 6 mounted on the upper shell 5, an outlet ring 9 sleeved on the inlet column 6, an adjustment component 10 provided on the inlet column 6 to enhance the separation effect, and a flocculation pretreatment flocculation component 11 provided on the base 1, the output port of the flocculation component 11 being connected to the inlet column 6.

[0023] When waste mineral oil needs to be treated, the waste mineral oil is fed into the flocculation component 11 and mixed with flocculant. Under the action of flocculant, the oil-water interface is destroyed and emulsions are eliminated, so that solid particles are destabilized and released. At the same time, impurity particles and water are connected and entangled to form larger and denser flocculent patterns, which facilitates subsequent separation operations and can improve the separation effect. After flocculation treatment, the oil enters the centrifugal space formed by the centrifugal seat and the upper shell 5 through the inlet column 6. The motor 2 drives the centrifugal seat and the upper shell 5 to rotate at high speed through the main drive belt 12 and the rotating seat 3. Under the centrifugal force, the oil causes the larger flocs to concentrate at the slag discharge port 7, while the lighter oil moves upward along the outer wall of the inlet column 6 and is discharged from the outlet ring 9. The oil is first flocculated to form larger flocs of impurities, and then further separated by centrifugal force, which effectively improves the quality of impurity separation in the oil.

[0024] The adjustment assembly 10 includes a disc 1002, a neutral hole 1003, a water passage hole 1004, a retaining ring 1006, a turbidity detector 1007, and an interval electric telescopic rod 1008; Multiple fixing rings 1006 are slidably installed on the liquid inlet column 6. Two adjacent fixing rings 1006 are connected by an interval electric telescopic rod 1008. A disc 1002 is installed on the fixing ring 1006. A water passage hole 1004 and a neutral hole 1003 are opened on the disc 1002. A turbidity detector 1007 is installed inside the liquid inlet column 6.

[0025] After the oil enters the centrifuge seat, it is distributed between each disc 1002. Under the centrifugation action, the impurity flocs move outward along the disc 1002, and the oil droplets gather upward along the outer wall of the liquid inlet column 6 through the water passage 1004. The neutral hole 1003 ensures that the oil can be smoothly dispersed upward, so that the oil can be distributed between each disc 1002. The setting of the disc 1002 shortens the settling distance of impurities and improves the separation efficiency. The spacing of the discs 1002 determines the separation efficiency. Therefore, different disc spacings are required for oils with different impurity contents to ensure high separation efficiency and throughput. The centrifugally separated oil first passes through the turbidity detector 1007. The turbidity detector 1007 is electrically connected to the uppermost spaced electric telescopic rod 1008, and adjacent spaced electric telescopic rods 1008 are electrically connected. The uppermost disc 1002 is fixed on the inlet column 6. The uppermost spaced electric telescopic rod 1008 will extend and retract according to the detection result of the turbidity detector 1007 to adjust the spacing between the two uppermost discs 1002. At the same time, the spaced electric telescopic rod 1008 controls the lower spaced electric telescopic rod 1008 to extend or retract synchronously. By adjusting the disc spacing by detecting the impurity content in real time, the separation efficiency is improved while ensuring throughput. The control method of controlling the lower electric telescopic pole by using the upper spaced electric telescopic pole 1008 simplifies the control process, shortens the control path, and reduces the risk of failure.

[0026] The regulating assembly 10 also includes a diffuser 1009, a slide bar 1010, a guide plate 1011, a guide slide plate 1012, and a connecting rod 1013; A diffuser 1009 is installed at the bottom of the liquid inlet column 6. A slide bar 1010 is installed on the centrifuge seat. A flow guide plate 1011 is installed on the slide bar 1010. A flow guide slide plate 1012 is slidably installed on the slide bar 1010. The flow guide slide plate 1012 is located on the side of the flow guide plate 1011 close to the liquid inlet column 6. The flow guide slide plate 1012 is connected to a disc 1002 closest to the centrifuge seat through a connecting rod 1013.

[0027] Initially, the guide plate 1012 is tightly attached to the guide base plate 1011. As the spacing between the discs 1002 decreases, the oil entering from the bottom of the inlet column 6 is initially distributed by the guide base plate 1011, allowing the oil to flow evenly to the discs 1002. As the spacing between the discs 1002 decreases, the distance between the guide base plate 1011 and the lowest disc 1002 will increase, causing eddies and disrupting stratification, thus affecting the separation efficiency. The guide plate 1012, which can move upward with the lowest disc 1002, continues to guide the oil, ensuring stable and orderly contact with the discs 1002, further ensuring the centrifugal separation efficiency.

[0028] The liquid inlet column 6 has an installation groove 1001. The center of the disc 1002 has multiple protrusions 1005, which extend into the installation groove 1001. The fixing ring 1006 is slidably installed in the installation groove 1001. Multiple protrusions 1005 on a disc 1002 are connected by the same fixing ring 1006.

[0029] The mounting groove 1001 and the protrusion 1005 form a locking position, which can prevent the disc 1002 from slipping during high-speed rotation, thereby improving the installation stability of the disc 1002. The fixing ring 1006 rigidly connects the inner side of the disc 1002, ensuring uniform movement of the disc 1002 when adjusting the spacing, ensuring that the spacing of the disc 1002 is the same at every point, reducing the shear force on the oil, and further improving the centrifugal separation efficiency.

[0030] The flocculation assembly 11 includes an installation plate 1101, a flocculation box 1102, a discharge port 1103, a gate 1104, a partition 1105, a settling chamber 1106, and a feed box 1107. A mounting plate 1101 is installed on the base 1, and a flocculation box 1102 is installed on the mounting plate 1101. A discharge port 1103 is opened at the bottom of the flocculation box 1102. A liquid inlet column 6 passes through the mounting plate 1101 and is connected to the inlet. A gate 1104 is installed inside the flocculation box 1102 near the discharge port 1103. A partition 1105 is installed inside the flocculation box 1102 away from the discharge port 1103. A settling chamber 1106 is located between the partition 1105 and the gate 1104. A feed box 1107 for mixing is installed between the partition 1105 and the wall away from the discharge port 1103. A pump 1121 is installed inside the flocculation box 1102, and the output end of the pump 1121 is connected to the discharge port 1103.

[0031] Waste mineral oil is fed into the feed tank 1107 through the inlet above the feed tank 1107 and mixed with flocculant. After mixing, it enters the settling chamber 1106 and is left to stand for a period of time before being fed into the liquid column 6 through the outlet 1103 for centrifugation. The flocs formed after the addition of flocculant to the oil will settle naturally in the settling area. After settling, the pump 1121 will pump the upper layer of oil to the outlet 1103. Through settling, large flocs that can be separated by gravity are removed in advance, reducing the load on the centrifuge and allowing the centrifugal separation to focus on processing fine particle flocs, thereby improving the quality of the oil after separation.

[0032] The flocculation assembly 11 also includes a hollow tube 1108, an impeller 1109, a nozzle 1110, a connecting rod 1111, an agitator 1112, a reducer 1113, and a flocculation conveyor belt; A hollow tube 1108 is installed on the feed box 1107, and an impeller 1109 is installed on the hollow tube 1108. The impeller 1109 is located inside the feed box 1107. A nozzle 1110 is partially opened on the hollow tube 1108 between the adjacent blades of the impeller 1109. A connecting rod 1111 is installed at the lower end of the hollow tube 1108, and an agitator 1112 is installed on the connecting rod 1111. The agitator 1112 is located outside the feed box 1107. A reducer 1113 is installed at the other output end of the motor 2. The output end of the reducer 1113 is connected to the hollow tube 1108 through a flocculation transmission belt 1114.

[0033] Flocculant is introduced into the upper end of the hollow pipe 1108. When waste mineral oil is introduced into the mixing tank, the motor 2 drives the impeller 1109 to rotate through the reducer and the flocculation transmission belt 1114. When the impeller 1109 rotates, the oil flows down along the gap between the blades of the impeller 1109. At this time, the flocculant gradually mixes with the oil from the nozzle 1110, and at the same time, the oil is stirred to promote the uniformity of mixing and improve the flocculation effect, thereby further improving the oil treatment efficiency.

[0034] The flocculation assembly 11 also includes a slide rail 1115, a touch sensor 1116, a slider 1117, an adjustable electric telescopic rod 1118, a float 1119, and a flow rate sensor 1120; A slide rail 1115 is installed on the side of the partition 1105 near the settling chamber 1106. A slider 1117 and a touch sensor 1116 are slidably installed on the slide rail 1115. The touch sensor 1116 is located above the slider 1117. An adjustable electric telescopic rod 1118 is installed on the partition 1105. One end of the adjustable electric telescopic rod 1118 is connected to the touch sensor 1116. The input end of the pump 1121 is connected to the float 1119.

[0035] The float 1119 rises with the rise of the liquid level. When the float 1119 drives the slider 1117 to contact the touch sensor 1116, the touch sensor 1116 will send a signal to stop feeding at a time. After the oil in the settling chamber 1106 is pumped out, flocculation and mixing are carried out again. Different flow rates will result in different times when the settling chamber 1106 is full, that is, the settling time of the oil that enters first is different. Therefore, when the flow rate increases, the flow rate sensor 1120 sends an electrical signal to control the electric telescopic rod to move the touch sensor 1116 upward, prolonging the total settling time and ensuring the sedimentation effect of impurities. Connecting the input end of the pump 1121 to the float 1119 can prevent the suction of settled particles from the bottom of the settling chamber 1106.

[0036] The centrifuge base is cone-shaped with the opening facing the upper shell 5. The slag discharge port 7 is located at the largest diameter. A slag collector 8 is installed on the base 1 and is sleeved on the outside of the slag discharge port 7.

[0037] The conical design allows particulate impurities to concentrate at the slag discharge port 7. A timed valve is installed at the slag discharge port 7 to discharge slag, allowing the waste slag to be thrown into the slag collector 8 for collection, thereby improving slag discharge efficiency and the sustainability of centrifugal filtration.

[0038] The impurity removal process of the waste mineral oil regeneration flocculation centrifugal impurity removal device provided in this application includes the following steps: Step 1: Input waste mineral oil into flocculation component 11, add flocculant through flocculation component 11 and stir; Step 2: The flocculated oil is allowed to settle in the flocculation component 11, and then fed into the centrifuge chamber composed of the centrifuge seat 4 and the upper shell 5 through the liquid inlet column 6; Step 3: Motor 2 drives centrifuge seat 4 to rotate via main drive belt 12 for centrifugal separation.

[0039] Working principle of the invention: When waste mineral oil needs to be treated, the waste mineral oil is fed into the flocculation component 11 and mixed with flocculant. Under the action of flocculant, the oil-water interface is destroyed and emulsions are eliminated, so that solid particles are destabilized and released. At the same time, impurity particles and water are connected and entangled to form larger and denser flocculent patterns, which facilitates subsequent separation operations and can improve the separation effect. After flocculation treatment, the oil enters the centrifugal space formed by the centrifugal seat and the upper shell 5 through the inlet column 6. The motor 2 drives the centrifugal seat and the upper shell 5 to rotate at high speed through the main drive belt 12 and the rotating seat 3. Under the centrifugal force, the oil causes the larger flocs to concentrate at the slag discharge port 7, while the lighter oil moves upward along the outer wall of the inlet column 6 and is discharged from the outlet ring 9. The oil is first flocculated to form larger flocs of impurities, and then further separated by centrifugal force, which effectively improves the quality of impurity separation in the oil.

[0040] After the oil enters the centrifuge seat, it is distributed between each disc 1002. Under the centrifugation action, the impurity flocs move outward along the disc 1002, and the oil droplets gather upward along the outer wall of the liquid inlet column 6 through the water passage 1004. The neutral hole 1003 ensures that the oil can be smoothly dispersed upward, so that the oil can be distributed between each disc 1002. The setting of the disc 1002 shortens the settling distance of impurities and improves the separation efficiency. The spacing of the discs 1002 determines the separation efficiency. Therefore, different disc spacings are required for oils with different impurity contents to ensure high separation efficiency and throughput. The centrifugally separated oil first passes through the turbidity detector 1007. The turbidity detector 1007 is electrically connected to the uppermost spaced electric telescopic rod 1008, and adjacent spaced electric telescopic rods 1008 are electrically connected. The uppermost disc 1002 is fixed on the inlet column 6. The uppermost spaced electric telescopic rod 1008 will extend and retract according to the detection result of the turbidity detector 1007 to adjust the spacing between the two uppermost discs 1002. At the same time, the spaced electric telescopic rod 1008 controls the lower spaced electric telescopic rod 1008 to extend or retract synchronously. By adjusting the disc spacing by detecting the impurity content in real time, the separation efficiency is improved while ensuring throughput. The control method of controlling the lower electric telescopic pole by using the upper spaced electric telescopic pole 1008 simplifies the control process, shortens the control path, and reduces the risk of failure.

[0041] Flocculant is introduced into the upper end of the hollow pipe 1108. When waste mineral oil is introduced into the mixing tank, the motor 2 drives the impeller 1109 to rotate through the reducer and the flocculation transmission belt 1114. When the impeller 1109 rotates, the oil flows down along the gap between the blades of the impeller 1109. At this time, the flocculant gradually mixes with the oil from the nozzle 1110, and at the same time, the oil is stirred to promote the uniformity of mixing and improve the flocculation effect, thereby further improving the oil treatment efficiency.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
