Description

Technical Field

[0001] This utility model relates to the field of distillation apparatus technology, and more specifically, to a waste lubricating oil regeneration distillation apparatus. Background Technology

[0002] Waste lubricating oil regeneration distillation equipment is a device that removes impurities from waste lubricating oil and recovers base oil or light fuel oil through physical or chemical methods.

[0003] Currently, before distilling waste lubricating oil, a pre-filtration system is typically installed before the distillation tank. The waste lubricating oil is added to a filtration mechanism, where iron filings are filtered and separated from the oil through filter plates. The filtered waste lubricating oil is then added to the distillation apparatus for further distillation, allowing the recovery of the base oil. However, in actual use, after filtering the waste lubricating oil, the filtered iron filings remain on the filter plates. At this point, the filter plates need to be pulled out to remove the iron filings from the filtration mechanism for cleaning. This requires frequent insertion and removal of the filter plates, making the operation cumbersome and requiring improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a waste lubricating oil regeneration distillation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A waste lubricating oil regeneration distillation device includes a distillation tank with a connecting pipe for adding waste lubricating oil. One end of the connecting pipe is equipped with a filter box for filtering the waste lubricating oil. The filter box has a chamber, and an oil filling pipe connected to the chamber is provided on the outer wall of the filter box for adding waste lubricating oil to the chamber. The chamber also has a filter box for filtering the waste lubricating oil. The chamber is equipped with a liftable electromagnet for magnetically attracting iron filings in the filter box. The outer wall of the filter box has a slot connected to the chamber, and a retractable collection box is provided through the slot in the chamber for collecting the iron filings attracted by the electromagnet. The filter box is equipped with a drive assembly, and the lifting of the electromagnet drives the drive assembly to extend the collection box out of the chamber or retract it into the chamber.

[0006] Furthermore, the outer wall of the filter box is provided with a sliding groove connecting the chamber along its width direction; the drive assembly includes a drive block provided on the side wall of the collection box, the drive block extends out of the chamber through the sliding groove, the two ends of the sliding groove are provided with mounting plates, and a rotatable screw is provided between the mounting plates. The screw thread passes through the drive block, and the rotation of the screw is used to drive the drive block to drive the collection box to extend out of the chamber or retract into the chamber; the filter box is also provided with a power assembly for driving the screw to rotate.

[0007] Furthermore, the side wall of the filter box is provided with a drive groove that connects to the chamber along its height direction; the power assembly includes a rack mounted on an electromagnet via a connecting block, the rack being arranged along the height direction of the drive groove; the power assembly also includes a first gear mounted on a corresponding mounting plate and meshing with the rack, one end of a lead screw extending through the corresponding mounting plate, and a second gear meshing with the first gear at the end of its extended end, the diameter of the first gear being larger than the diameter of the second gear, the electromagnet driving the rack to rise and fall, thereby enabling the first gear to drive the second gear and the lead screw to rotate.

[0008] Furthermore, the collection box has an opening at the top, and its bottom wall forms a slope, with the height of the slope decreasing sequentially in the direction of the slot opening.

[0009] Furthermore, the filter box includes an upper shell and a lower shell. The lower end of the upper shell extends outward to form a first mounting part, and the upper end of the lower shell extends outward to form a second mounting part.

[0010] Furthermore, an electric push rod is installed on the upper side wall of the filter box, and the output end of the electric push rod extends into the chamber and is connected to the upper side of the electromagnet.

[0011] Furthermore, a water pump is installed on the bottom wall of the chamber, and one end of the connecting pipe is connected to the output end of the water pump.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of the driving component, enables the electromagnet to move downward, thereby driving the driving component to drive the collection box to extend out of the cavity through the slot, thus avoiding the collection box interfering with the downward movement of the electromagnet. The electromagnet can move upward, thereby driving the driving component to drive the collection box to retract out of the cavity. When the electromagnet resets, the iron filings attracted to the electromagnet can fall onto the collection box. When the electric push rod pushes the electromagnet downward again, causing the collection box to extend out of the cavity, the operator can clean the iron filings collected in the collection box without the need for the operator to manually pull out the collection box, making the operation convenient.

[0013] This utility model involves fixing the filter box inside the lower housing. The side wall of the lower housing has an opening along its width, and a side plate is installed at the opening by screws. When the filter box needs to be cleaned, the side plate is removed by loosening the screws. The operator can then reach into the lower housing and loosen the screws to release the filter box from its fixed installation inside the lower housing, making it easy for the operator to remove the filter box for cleaning.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0022] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0023] Combination Figures 1-6This embodiment of a waste lubricating oil regeneration distillation apparatus includes a distillation tank 105. The distillation tank 105 is equipped with a connecting pipe 104 for adding waste lubricating oil into the tank. One end of the connecting pipe 104 is equipped with a filter box 100 for filtering the waste lubricating oil. The filter box 100 contains a chamber 200. An oil filling pipe 101, communicating with the chamber 200, is located on the outer wall of the filter box 100. The oil filling pipe 101 is used to add waste lubricating oil to the chamber 200. The chamber 200 also contains a filter for filtering the waste lubricating oil. The filter box 201 is equipped with an electromagnet 205 that can be raised and lowered and is used to magnetically attract iron filings in the filter box 201. The outer wall of the filter box 100 is provided with a slot that communicates with the chamber 200. A retractable collection box 202 is provided in the chamber 200 through the slot. The collection box 202 is used to collect the iron filings attracted by the electromagnet 205. The filter box 100 is provided with a drive assembly. The raising and lowering of the electromagnet 205 is used to drive the drive assembly to drive the collection box 202 to extend out of the chamber 200 or retract into the chamber 200.

[0024] In practical use, the filter box 201 has an opening at the top, and its bottom wall is evenly distributed with multiple filter holes for filtration. Waste lubricating oil is added into the filter box 100 through the filler pipe 101, allowing the waste lubricating oil to enter the filter box 201 and be filtered through the filter holes. The filtered waste lubricating oil then passes through the filter holes and enters the chamber 200 located below the filter box 201, where the filtered iron filings remain. A water pump is installed on the bottom wall of the chamber 200, and one end of the connecting pipe 104 is connected to the output end of the water pump, while the other end is connected to the distillation tank 10. 5. The distillation tank 105 is an existing structure, which mainly includes a tank body. A heating component for heating is installed inside the tank body. The upper end of the tank body is connected to a steam outlet pipe 106, and the lower end is connected to an oil outlet pipe 107. The filtered waste lubricating oil is pumped into the distillation tank 105 through the connecting pipe 104 by a water pump. Since the water mixed in the waste lubricating oil is lower than the boiling point of the waste lubricating oil, the waste lubricating oil is heated by the heating component to distill it, so that the water can be evaporated through the steam outlet pipe 106, thereby obtaining waste lubricating oil with higher purity. It is discharged out of the tank body through the oil outlet pipe 107 for subsequent processing, thus completing the distillation of waste lubricating oil. It should be noted that a solenoid valve is provided on the connecting pipe 104, which can prevent water vapor from entering the chamber 200 through the connecting pipe 104; In actual use, an electric push rod 102 is installed on the upper side wall of the filter box 201. The output end of the electric push rod 102 extends into the chamber 200 and is connected to the upper side of the electromagnet 205. A power distribution box is also installed on the upper side wall of the filter box 201 to supply power to the electromagnet 205. When it is necessary to remove the iron filings from the filter box 201, the electric push rod 102 pushes the electromagnet 205 downward. During this process, the downward movement of the electromagnet 205 can drive the drive assembly to drive the collection box 202 to extend out of the chamber 200 through the slot, so as to avoid the collection box 202 interfering with the downward movement of the electromagnet 205. When the collection box 202 extends out of the chamber 200 and the electromagnet 205 continues to move downward, the power distribution box supplies power to the electromagnet 205, so that the electromagnet 205 can generate magnetic force to attract the iron filings in the filter box 201. After the iron filings in the filter box 201 have been adsorbed, the electric push rod 102 drives the electromagnet 205 to move upward. During this process, the upward movement of the electromagnet 205 can drive the drive assembly to drive the collection box 202 to retract into the chamber 200. When the electromagnet 205 resets, the collection box 202 can also reset. At this time, the power distribution box stops supplying power to the electromagnet 205. At this time, the electromagnet 205 loses its magnetic force, and the iron filings adsorbed on the electromagnet 205 can fall onto the collection box 202 so that the iron filings can be collected. When the electric push rod 102 pushes the electromagnet 205 down to attract the iron filings in the filter box 201 so that the collection box 202 extends out of the chamber 200, the operator can then clean the iron filings collected in the collection box 202, making it convenient to operate without the need for the operator to manually pull out the collection box 202. Specifically, in order to facilitate the cleaning of iron filings in the collection box 202 by the operator, in this embodiment, the collection box 202 is provided with an opening at the top and its bottom wall forms an inclined surface 500, the height of the inclined surface 500 towards the slot opening decreases sequentially; so that the iron filings in the collection box 202 can be accumulated in one place, making it easier for the operator to clean. It should be noted that the collection box 202 is located above the opening of the refueling pipe 101 inside the chamber 200, thereby preventing waste lubricating oil from entering the collection box 202.

[0025] Combination such as Figures 2-5As shown, in this embodiment, a sliding groove 301 communicating with the chamber 200 is provided on the outer side wall of the filter box 100 along its width direction; the driving assembly includes a driving block 300 provided on the side wall of the collection box 202, the driving block 300 extends out of the chamber 200 through the sliding groove 301, the two ends of the sliding groove 301 are provided with mounting plates 103, and a rotatable lead screw 203 is provided between the mounting plates 103. The lead screw 203 is threaded through the driving block 300, and the rotation of the lead screw 203 is used to drive the driving block 300 to drive the collection box 202 to extend out of the chamber 200 or retract into the chamber 200; the filter box 100 is also provided with a power assembly for driving the lead screw 203 to rotate.

[0026] In actual use, one end of the drive block 300 protrudes to form a fixing part, which is welded to the side wall of the collection box 202, so that the collection box 202 can be fixedly connected to the drive block 300. At the same time, the side wall of the fixing part slides against the corresponding side wall of the sliding groove 301, so that the sliding groove 301 can limit the fixing part. In actual use, the electromagnet 205 moves downward, driving the power assembly to rotate the lead screw 203. The sliding groove 301 can limit the fixed part, so that the drive block 300 can drive the collection box 202 to move on the lead screw 203, thereby allowing the collection box 202 to extend out of the chamber 200 through the groove. When the electromagnet 205 moves upward, driving the power assembly to rotate the lead screw 203 in the opposite direction, and when the electromagnet 205 moves upward to reset, the collection box 202 can retract into the chamber 200 through the groove and reset. The mounting plate 103 is fixedly installed on the side wall of the filter box 100, and both ends of the lead screw 203 are rotatably installed on the corresponding mounting plate 103 through bearings, so that the lead screw 203 can be rotatably installed. It should be noted that, since the side wall of the filter box 100 has a certain thickness, when the electromagnet 205 descends to the position of the collection box 202, part of the collection box 202 is still located inside the chamber 200. At this time, there is a gap between the side wall of the collection box 202 facing the chamber 200 and the corresponding side wall of the chamber 200. In order to prevent the collection box 202 from interfering with the downward movement of the electromagnet 205, the width of the electromagnet 205 in this embodiment is smaller than this gap, thereby preventing the collection box 202 from interfering with the downward movement of the electromagnet 205.

[0027] Combination Figures 4-6As shown, in this embodiment, the side wall of the filter box 100 is provided with a drive groove 204 that connects to the chamber 200 along its height direction; the power assembly includes a rack 402 mounted on an electromagnet 205 via a connecting block, the rack 402 being arranged along the height direction of the drive groove 204; the power assembly also includes a first gear 401 mounted on a corresponding mounting plate 103 and meshing with the rack 402, one end of the lead screw 203 extending through the corresponding mounting plate 103, and a second gear 400 meshing with the first gear 401 at the end of its extended end, the diameter of the first gear 401 being larger than the diameter of the second gear 400, the electromagnet 205 driving the rack 402 to rise and fall, thereby enabling the first gear 401 to drive the second gear 400 and the lead screw 203 to rotate.

[0028] In actual use, one end of the connecting block is welded to the electromagnet 205, and the other end extends out through the drive groove 204. One side wall of the rack 402 is fixedly installed at the end of the extended end of the connecting block, so that when the electric push rod 102 drives the electromagnet 205 to move down, the electromagnet 205 can drive the rack 402 to move down through the connecting block, thereby driving the first gear 401 to drive the second gear 400 to rotate, so that the second gear 400 can drive the lead screw 203 to rotate. In actual use, the diameter of the first gear 401 is larger than the diameter of the second gear 400, and the number of teeth is proportional, so that the second gear 400 can rotate multiple times for the first gear 401 to rotate once, thereby effectively increasing the stroke of the drive block 300 on the lead screw 203. The first gear 401 is rotatably mounted on the corresponding mounting plate 103 via a rotating shaft, and the second gear 400 is fixedly mounted at the end of the extended end of the lead screw 203.

[0029] Combination Figure 6 As shown, in this embodiment, the filter box 100 includes an upper shell 302 and a lower shell 600. The lower end of the upper shell 302 extends outward to form a first mounting portion 303, and the upper end of the lower shell 600 extends outward to form a second mounting portion 601. The first mounting portion 303 and the second mounting portion 601 are connected by screws. The filter box 201 is fixedly installed on the inner side wall of the lower shell 600.

[0030] In actual use, the filter box 201 is fixedly installed in the lower housing 600 by screws. The side wall of the lower housing 600 has an opening along its width, and a side plate is installed at the opening by screws. The opposite side wall of the lower housing 600 has a slot for sliding installation of the filter box 201, so that the filter box 201 can be slidably installed in the lower housing 600. When it is necessary to clean the filter box 201, the side plate is removed by loosening the screws. The operator can then reach into the lower housing 600 and loosen the screws to release the filter box 201 from the fixed installation in the lower housing 600, making it easy for the operator to pull out the filter box 201 for cleaning. The outer side wall of the filter box 201 is provided with rubber pads, so that the side wall of the filter box 201 can be sealed with the inner side wall of the lower housing 600. The side wall of the side plate is also provided with rubber pads, so that the side plate and the lower housing 600 can be sealed, thereby better preventing the leakage of waste lubricating oil. The filter box 100 is divided into an upper housing 302 and a lower housing 600, which facilitates the installation of the drive assembly and other components. In actual use, the first mounting part 303 and the second mounting part 601 are provided with relatively aligned notches to facilitate the downward movement of the rack 402.

[0031] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
