Description

Technical Field

[0001] This utility model relates to the field of waste mineral oil recycling technology, specifically a waste mineral oil dehydration and slag removal device. Background Technology

[0002] Waste mineral oil recycling refers to the process of removing contaminants (moisture, mechanical impurities, oxidation products, additive degradation products, etc.) from waste mineral oil (such as waste lubricating oil, waste hydraulic oil, waste transformer oil, etc.) through physical, chemical or biological means, and restoring some or all of its performance so that it can be reused as a raw material or product. Its core objective is to achieve resource recycling, reduce environmental pollution, and reduce dependence on crude oil.

[0003] An existing patent (publication number: CN221155414U) discloses a distillation apparatus for waste mineral oil recovery, relating to the field of distillation apparatuses. It includes a base plate, with fixed plates fixedly installed on both sides of the top of the base plate. Support plates are fixedly installed on the top and bottom of opposite sides of the two fixed plates. A distillation tank is fixedly installed between the opposite sides of the two support plates. A feed inlet is connected to the right side of the top of the distillation tank, and a motor is fixedly installed on the top of the distillation tank. Waste mineral oil enters the interior of the distillation tank through a feed pipe. Heating wires heat and distill the waste mineral oil inside the tank. When the stirring rod rotates, it also drives the connecting plate and scraper to rotate. The scraper, while rotating, can clean residual dirt on the inner wall of the distillation tank. Through the cooperation of limiting components and limiting blocks, the filter screen can be quickly installed and removed, making it more convenient to disassemble and clean the filter screen, thus solving the problems in the prior art.

[0004] When the above-mentioned device is in use, the filter screen can be quickly installed and disassembled through the cooperation of the limiting component and the limiting block. It is more convenient when the filter screen needs to be disassembled and cleaned, thus solving the problem in the background technology. However, after filtering the residue, oil will adhere to the surface of the residue. The above-mentioned device lacks the ability to process the residue after filtering it and cannot extract the waste mineral oil attached to the residue. The recovery efficiency is poor, and the filter screen needs to be removed and cleaned after each use, which is cumbersome and cannot be carried out continuously. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waste mineral oil dehydration and slag removal device, which has the advantages of extracting mineral oil from the residue and discharging the residue for continuous operation, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste mineral oil dehydration and slag removal device, comprising a slag removal tank and a distillation tank. The inner wall of the slag removal tank is equipped with a filter plate, and a vertically sliding sleeve is provided inside the slag removal tank. Two supports are fixedly connected to the outer surface of the sliding sleeve. A sliding frame is slidably inserted into the bottom end of the left support. A squeezing roller for squeezing residue is rotatably connected to the inner wall of the sliding frame. Two springs are fixedly connected between the sliding frame and the left support.

[0007] A collection frame is fixedly connected to the bottom of the bracket on the right side. The collection frame is in contact with the filter plate. An extraction tube is fixedly connected to the rear end of the collection frame. The other end of the extraction tube is connected to the pump input end in the outside.

[0008] Furthermore, the upper end of the slag removal tank is rotatably connected to a rotating sealing cover, and a rotating rod is fixedly connected to the rotating sealing cover along the axis. The rotating rod passes through the filter plate, and a positioning groove is provided at the middle end of the rotating rod. The sliding sleeve is slidably sleeved with the rotating rod through the positioning groove.

[0009] The above solution limits the sliding sleeve by opening a positioning groove, ensuring that the sliding sleeve can only slide within the positioning groove. This ensures that the sliding sleeve moves stably in the vertical direction and avoids uneven contact between the squeezing roller and the filter plate or tilting of the collection frame due to deviation, thus preventing slag leakage.

[0010] Furthermore, an electric push rod is fixedly connected to the upper end of the rotating rod, and the output end of the electric push rod is fixedly connected to the upper end of the right-side bracket.

[0011] The above scheme uses an electric push rod to drive the sliding sleeve to descend, causing the extrusion roller to contact the filter plate and extrude the residue on the surface of the filter plate. This causes the mineral oil adhering to the residue to separate from the residue, and the mineral oil to fall to the bottom of the slag removal tank.

[0012] Furthermore, the upper end of the slag removal tank is fixedly connected to a feed pipe, and the lower ends of both the slag removal tank and the distillation tank are fixedly connected to drain pipes. Valves are installed on the outer surfaces of the feed pipe and the two drain pipes.

[0013] The above solution allows for the sealing of the slag removal tank with valves, preventing leakage of mineral oil and mixed wastewater.

[0014] Furthermore, an oil scraper is fixedly connected to the bottom end of the rotating rod, and the oil scraper is in contact with the inner wall of the slag removal tank.

[0015] The above solution allows for the cleaning of the inner wall of the slag removal tank by installing an oil scraper, preventing waste mineral oil from adhering to the inner wall of the tank.

[0016] Furthermore, an extraction pump is provided between the slag removal tank and the distillation tank. The output end of the extraction pump is fixedly connected to an extraction pipe, which is located inside the left drain pipe. The output end of the extraction pump is fixedly connected to the distillation tank, and a resistance heating plate is installed in the cavity formed at the bottom of the distillation tank.

[0017] Through the above scheme, after the wastewater in the slag removal tank is discharged by the pump, the minerals in the left drain pipe are extracted and transported to the distillation tank. By utilizing the different boiling points of the different components in the mineral oil, the components are separated after distillation, thus realizing the recovery of different types.

[0018] Furthermore, a conical frame is fixedly connected to the inner wall of the distillation jar, and a sorting tube is fixedly connected to the middle end of the distillation jar.

[0019] The above scheme allows the conical frame to contact the low-boiling-point light mineral oil and then discharge it through the sorting tube, thus achieving the separation of light mineral oil and base mineral oil.

[0020] Furthermore, a rotating column is rotatably connected to the inner top wall of the distillation tank along its axis, and multiple stirring plates are fixedly connected to the bottom end of the rotating column. The upper ends of both the rotating column and the rotating rod are fixedly connected to the output end of an external motor.

[0021] The above scheme allows the stirring plate to agitate the mineral oil in the distillation tank, ensuring that the mineral oil is heated evenly and thus improving the distillation efficiency.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0023] This waste mineral oil dehydration and slag removal equipment uses a filter plate to filter impurities in the mineral oil, trapping them on the filter plate. A squeeze roller, during its rotation, compresses the residue on the filter plate, causing the mineral oil adhering to the residue to fall to the bottom of the slag removal tank. A collection frame, during rotation, shovels the residue into the collection frame, and an external pump then removes it from the slag removal tank. This system not only extracts the mineral oil from the residue but also discharges it from the slag removal tank, facilitating continuous operation. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figures 1-4 This embodiment of a waste mineral oil dehydration and slag removal device includes a slag removal tank 1 and a distillation tank 2. A filter plate 3 is installed on the inner wall of the slag removal tank 1. A vertically sliding sleeve 4 is provided inside the slag removal tank 1. Two supports 5 are fixedly connected to the outer surface of the sliding sleeve 4. A sliding frame 6 is slidably inserted into the bottom end of the left support 5. A squeezing roller 7 for squeezing residue is rotatably connected to the inner wall of the sliding frame 6. Two springs 8 are fixedly connected between the sliding frame 6 and the left support 5. By setting the filter plate 3, impurities in the mineral oil can be filtered and retained on the filter plate 3. By setting the squeezing roller 7, the residue on the filter plate 3 can be squeezed during the rotation of the squeezing roller 7, causing the mineral oil adhering to the surface of the residue to fall to the bottom of the slag removal tank 1.

[0032] A collection frame 9 is fixedly connected to the bottom of the right support 5. The collection frame 9 is in contact with the filter plate 3. The rear end of the collection frame 9 is fixedly connected to the extraction pipe 10. The other end of the extraction pipe 10 is connected to the input end of the external pump. The collection frame 9 can shovel the residue into the collection frame 9 when it rotates, and then pump it out of the slag removal tank 1 through the external pump. This not only extracts the mineral oil in the residue, but also discharges the residue from the slag removal tank 1, which is convenient for continuous operation.

[0033] A rotating sealing cover 11 is rotatably connected to the upper end of the slag removal tank 1. A rotating rod 12 is fixedly connected to the rotating sealing cover 11 along the axis. The extraction pipe 10 passes through the rotating sealing cover 11, and the rotating rod 12 passes through the filter plate 3. A positioning groove 13 is provided at the middle end of the rotating rod 12. The sliding sleeve 4 is slidably sleeved with the rotating rod 12 through the positioning groove 13. The positioning groove 13 can limit the sliding sleeve 4, so that the sliding sleeve 4 can only slide within the positioning groove 13, ensuring that the sliding sleeve 4 moves stably in the vertical direction and avoiding uneven contact between the squeezing roller 7 and the filter plate 3 or tilting and leakage of slag due to deviation. An electric push rod 14 is fixedly connected to the upper end of the rotating rod 12. The output end of the electric push rod 14 is fixedly connected to the upper end of the right support 5. The electric push rod 14 drives the sliding sleeve 4 to descend, so that the squeezing roller 7 contacts the filter plate 3 and squeezes the residue on the surface of the filter plate 3, so that the mineral oil attached to the residue is separated from the residue and the mineral oil falls to the bottom of the slag removal tank 1.

[0034] The upper end of the slag removal tank 1 is fixedly connected to a feed pipe 15. Both the lower ends of the slag removal tank 1 and the distillation tank 2 are fixedly connected to drain pipes 16. Valves 17 are installed on the outer surfaces of the feed pipe 15 and the two drain pipes 16. The valves 17 can seal the slag removal tank 1 to prevent leakage of mineral oil and adulterated wastewater. An oil scraper 18 is fixedly connected to the bottom end of the rotating rod 12. The oil scraper 18 contacts the inner wall of the slag removal tank 1, cleaning the inner wall of the slag removal tank 1 and preventing waste mineral oil from adhering to it. A pump 19 is installed between the pump 19 and the distillation tank 2. The output end of the pump 19 is fixedly connected to the extraction pipe 20, which is located inside the left drain pipe 16. The output end of the pump 19 is fixedly connected to the distillation tank 2. A resistance heating plate 21 is installed in the cavity formed at the bottom of the distillation tank 2. After the wastewater in the slag removal tank 1 is discharged, the pump 19 extracts the minerals in the left drain pipe 16 and transports them to the distillation tank 2. Due to the different boiling points of the different components in the mineral oil, the components are separated after distillation, and different types of minerals are recovered.

[0035] A conical frame 22 is fixedly connected to the inner wall of the distillation tank 2, and a sorting pipe 23 is fixedly connected to the middle end of the distillation tank 2. The conical frame 22 allows light mineral oil with a low boiling point to come into contact with the conical frame 22 and then be discharged through the sorting pipe 23, thereby separating the light mineral oil from the base mineral oil. A rotating column 24 is rotatably connected to the inner top wall of the distillation tank 2 along its axis. Multiple stirring plates 25 are fixedly connected to the bottom end of the rotating column 24. The upper ends of the rotating column 24 and the rotating rod 12 are both fixedly connected to the output end of an external motor. The stirring plates 25 can stir the mineral oil in the distillation tank 2, so that the mineral oil in the distillation tank 2 can be heated evenly, thereby improving the distillation efficiency.

[0036] The working principle of the above embodiment is as follows: First, waste mineral oil is injected into the slag removal tank 1 through the feed pipe 15. The mineral oil passing through the filter plate 3 will be filtered by the filter plate 3, and the residue will be retained on the filter plate 3. The filtered mineral oil will flow to the bottom of the slag removal tank 1. Then, the electric push rod 14 pushes the sliding sleeve 4 to slide in the positioning groove 13, so that the extrusion roller 7 contacts the filter plate 3, and the spring 8 is compressed. Then, the external motor drives the rotating rod 12 to rotate. During the rotation of the rotating rod 12, the extrusion roller 7 will rotate with the rotating rod 12 and filter the mineral oil. The residue on plate 3 is uniformly squeezed, and the mineral oil attached to the residue is discharged into the bottom of the slag removal tank 1 after being squeezed. Then, the electric push rod 14 pushes the sliding sleeve 4 to continue to descend, so that the collection frame 9 contacts the filter plate 3. By rotating the rotating rod 12, the collection frame 9 can clean the filter plate 3, which can prevent the filter plate 3 from becoming blocked. At the same time, it can shovel the residue on the filter plate 3 into the collection frame 9. Then, the external pump body transmits the suction to the collection frame 9 through the pipeline and extracts the residue in the collection frame 9 to prevent the residue from being retained in the slag removal tank 1.

[0037] After sedimentation, the mineral oil in the slag removal tank 1 will separate from the wastewater. Due to the difference in density, the mineral oil will float on the wastewater. Then, the valve 17 on the left drain pipe 16 is opened to allow the wastewater to be discharged through the drain pipe 16. After the wastewater is discharged, the valve 17 is closed, leaving the mineral oil in the left drain pipe 16. Then, the pump body transports the mineral oil to the distillation tank 2 through the extraction pipe 20. The resistance heating plate 21 in the distillation tank 2 generates heat and transfers it to the distillation tank 2. At this time, the external motor drives the rotating rod 12 to rotate, so that the rotating rod 12 can stir the mineral oil in the distillation tank 2 through the stirring plate 25, so that it can be heated evenly. The components with lower boiling points will evaporate first and be discharged through the classification pipe 23 along the conical frame 22. Finally, the valve 17 on the right is opened, and the distilled mineral oil will be discharged through the drain pipe 16 on the right.
