Description

Technical Field

[0001] This invention relates to the field of separation technology, and in particular to an aluminum wire waste oil separation system. Background Technology

[0002] During the drawing process of overhead aluminum and aluminum alloy cables, when the aluminum and aluminum alloy wires are controlled by the size of the die eye, a large amount of heat is generated during high-speed wire drawing. The wire drawing oil is immersed in the wire drawing oil to cool and provide a certain lubrication. However, the aluminum rod will wear away the aluminum powder on the surface of the aluminum rod through friction. During long-term wire drawing, the aluminum powder and wire drawing oil will mix together to form a mixture of aluminum mud and wire drawing oil.

[0003] To separate aluminum sludge from oil, Chinese Patent Publication No. CN105964421A discloses an oil-aluminum separator, which mainly uses centrifugal rotation to separate aluminum sludge and oil with different specific gravities. After centrifugation, the waste oil is discharged from the oil outlet, while the aluminum sludge adhering to the inner wall of the separation cylinder is removed by a scraper. However, due to the adhesive force of the aluminum sludge, the scraping resistance is relatively large, and it is also difficult to clean it completely. In view of this, this application proposes an aluminum wire waste oil separation system. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aluminum wire waste oil separation system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste oil separation system for aluminum wire includes a crusher, a centrifugal treatment device, a distillation reaction device, a storage tank, and a drying device. The centrifugal treatment device includes a housing, within which a separation cylinder is rotatably connected. A rotating mechanism for rotating the separation cylinder is installed within the housing. A reciprocating screw is rotatably connected within the separation cylinder, and a screw nut is provided on the reciprocating screw to cooperate with it. A conical scraper is fixedly connected to the screw nut via a connecting rod. The conical scraper has a through hole. A drive plate is fixedly connected to the upper end of the screw nut, and multiple openings are formed on the side wall of the drive plate. Each water pressure tank has a piston plate slidably connected within it. A water storage tank is fixedly connected to the inner wall of the separation cylinder. A drain pipe is connected to the lower end of the water storage tank. A corrugated pipe is connected to the end of the drain pipe away from the water storage tank. A water supply pipe is connected to the lower end of the corrugated pipe. The water supply pipe communicates with the interior of each water pressure tank through an inlet pipe. An outlet pipe communicating with each water pressure tank is installed on the drive plate. A one-way shut-off valve is installed in both the inlet and outlet pipes. Multiple transmission grooves are opened on the side wall of the drive plate. A moving mechanism for moving the piston plate is installed in each transmission groove.

[0007] Preferably, the moving mechanism includes a lifting rack slidably connected in the transmission groove, a transmission gear rotatably connected to the inner wall of the transmission groove, and the lifting rack meshing with the transmission gear. Multiple sets of drive mechanisms for rotating the transmission gear are installed in the separating cylinder.

[0008] Preferably, the driving mechanism includes a support rod and a limiting rack, wherein one end of the support rod is fixedly connected to the inner wall of the separation cylinder, and the other end of the support rod is fixedly connected to the limiting rack.

[0009] Preferably, an oil inlet pipe is installed on the side wall of the separator, a rotary joint is installed at the bottom of the separator, the lower end of the rotary joint is connected to an oil outlet pipe, and a control valve is installed inside the oil outlet pipe.

[0010] Preferably, the rotating mechanism includes a drive gear, a gear ring, and a first motor. The first motor is fixedly installed inside the device housing. The drive gear is rotatably connected to the bottom of the device housing and fixedly connected to the output shaft of the first motor. The gear ring is fixedly connected to the outer wall of the separation cylinder and meshes with the drive gear.

[0011] Preferably, a second motor is fixedly installed at the upper end of the separating cylinder, and the output shaft of the second motor is fixedly connected to a reciprocating lead screw.

[0012] Preferably, the water outlet pipe is a flexible hose, a pulley is rotatably connected to the inner wall of the transmission groove, a pull ring is fixedly connected to both the piston plate and the side wall of the water outlet pipe, a pull rope is provided on the pulley, and the two ends of the pull rope are respectively fixedly connected to the two pull rings.

[0013] The present invention has the following beneficial effects:

[0014] 1. By setting up a piston plate, a moving mechanism, an inlet pipe, and an outlet pipe, the moving mechanism drives the piston plate to move up and down continuously during the process of the conical scraper scraping and cleaning the aluminum sludge on the inner wall of the separator. This allows the cleaning water to be drawn from the water storage tank and discharged through the outlet pipe to rinse the inner wall of the separator, which can greatly reduce the adhesion resistance of the aluminum sludge and make the aluminum sludge on the inner wall of the separator fall off faster and more thoroughly.

[0015] 2. By setting the water outlet pipe as a flexible hose and installing components such as pulleys, pull ropes, and pull rings, the flexible hose can be pulled up and down by the pull rope while the moving mechanism drives the piston plate to move up and down. This increases the drainage range of the water outlet pipe and thus accelerates the removal efficiency of aluminum sludge. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figure 1-4 A waste oil separation system for aluminum wire includes a crusher, a centrifugal treatment device, a distillation reaction device, a storage tank, and a drying device. The centrifugal treatment device includes a device box 1, a separation cylinder 2 rotatably connected inside the device box 1, an oil inlet pipe 7 installed on the side wall of the separation cylinder 2, a rotary joint 15 installed at the bottom inside the separation cylinder 2, an oil outlet pipe 16 connected to the lower end of the rotary joint 15, and a control valve installed inside the oil outlet pipe 16.

[0023] The device housing 1 is equipped with a rotating mechanism that rotates the separating cylinder 2. The rotating mechanism includes a drive gear 4, a gear ring 5, and a first motor 3. The first motor 3 is fixedly installed inside the device housing 1. The drive gear 4 is rotatably connected to the bottom of the device housing 1 and is fixedly connected to the output shaft of the first motor 3. The gear ring 5 is fixedly connected to the outer wall of the separating cylinder 2 and meshes with the drive gear 4.

[0024] A reciprocating screw 8 is rotatably connected inside the separator cylinder 2, and a second motor 6 is fixedly installed at the upper end of the separator cylinder 2. The output shaft of the second motor 6 is fixedly connected to the reciprocating screw 8.

[0025] Furthermore, the reciprocating lead screw 8 is equipped with a lead screw nut 20 that cooperates with it. The lead screw nut 20 is fixedly connected to a conical scraper 13 via a connecting rod 14. The conical scraper 13 has a through hole 17. The upper end of the lead screw nut 20 is fixedly connected to a drive plate 21. The side wall of the drive plate 21 has multiple water pressure grooves 25. Each water pressure groove 25 is slidably connected to a piston plate 33. A water storage tank 9 is fixedly connected to the inner wall of the separator cylinder 2. (Refer to...) Figure 1 A water inlet pipe 10, which communicates with the inside of the water storage tank 9, is installed on the outer wall of the separator 2. Clean water can be added to the water storage tank 9 through the water inlet pipe 10.

[0026] The lower end of the water storage tank 9 is connected to a drain pipe 11. The end of the drain pipe 11 away from the water storage tank 9 is connected to a corrugated pipe 12. The lower end of the corrugated pipe 12 is connected to a water supply pipe 29, and the water supply pipe 29 is connected to the interior of each pressure tank 25 through a water inlet pipe 28. It should be noted that by setting the corrugated pipe 12, the free expansion and contraction characteristics of the corrugated pipe 12 can be used to cooperate with the up and down movement of the drive plate 21.

[0027] A water outlet pipe 27, which communicates with each water pressure tank 25, is installed on the drive plate 21. The water outlet pipe 27 is a flexible hose. A pulley 30 is rotatably connected to the inner wall of the transmission groove 22. Pull rings 32 are fixedly connected to the side walls of the piston plate 33 and the water outlet pipe 27. A pull rope 31 is provided on the pulley 30, and the two ends of the pull rope 31 are fixedly connected to the two pull rings 32 respectively. It should be noted that by setting up components such as the pull rope 31 and the pull rings 32, the piston plate 33 can pull the water outlet pipe 27 up and down by pulling the pull rope 31 during the movement, thereby increasing the drainage range of the water outlet pipe 27.

[0028] Both the inlet pipe 28 and the outlet pipe 27 are equipped with one-way shut-off valves. The side wall of the drive plate 21 has multiple transmission grooves 22, each containing a moving mechanism that moves the piston plate 33. It should be noted that the one-way shut-off valve in the inlet pipe 28 allows water to flow only from the inlet pipe 28 to the pressure tank 25, while the one-way shut-off valve in the outlet pipe 27 allows water to flow only from the pressure tank 25 to the outlet pipe.

[0029] The moving mechanism includes a lifting rack 24 that is slidably connected in the transmission groove 22. A transmission gear 23 is rotatably connected to the inner wall of the transmission groove 22, and the lifting rack 24 and the transmission gear 23 mesh with each other. Multiple sets of drive mechanisms that cause the transmission gear 23 to rotate are installed in the separation cylinder 2.

[0030] The drive mechanism includes a support rod 18 and a limiting rack 19, wherein one end of the support rod 18 is fixedly connected to the inner wall of the separation cylinder 2, and the other end of the support rod 18 is fixedly connected to the limiting rack 19. It should be noted that, referring to... Figure 1 and Figure 3Each set of drive mechanisms has six, and the six drive mechanisms are evenly distributed along the inner wall of the separation cylinder 2. Each set of drive mechanisms is evenly distributed along the vertical direction of the inner wall of the separation cylinder 2. Therefore, during the up-and-down movement of the drive plate 21 in the separation cylinder 2, the transmission gear 23 in the transmission groove 22 will pass through each limiting rack 19 in sequence, thereby causing the transmission gear 23 to rotate continuously.

[0031] Before separating the aluminum wire waste oil in the aforementioned device, the aluminum wire waste oil can be passed through three solvents and then separated by a separator to obtain a mixed solvent waste oil mixture and aluminum powder semi-finished product. The mixed solvent waste oil mixture is then recovered in a reaction vessel to obtain mixed solvent and wire drawing waste oil. The mixed solvent can be reused, and the wire drawing waste oil can be recycled. The aluminum powder semi-finished product is dried by a drying device to obtain aluminum powder. This invention not only achieves resource recycling but also reduces energy consumption, realizes the reuse of raw materials, and the solvent can be recycled and reused during the production process, greatly reducing production costs and improving resource utilization.

[0032] The specific process is as follows: The solvent and aluminum wire waste oil are mixed in proportion and then put into the crusher. After timed crushing, the mixture is put into this device for centrifugal treatment. The liquid enters the No. 1 storage tank, and the solid is mixed with the solvent in proportion and then put into the crusher for crushing again.

[0033] The mixture after secondary crushing is centrifuged again by this device. The liquid enters the No. 2 storage tank for storage, and the solid after secondary centrifugation is mixed with solvent in proportion and then put into the crusher for further crushing.

[0034] The mixture after three crushing processes is centrifuged three times in this device. The liquid is stored in storage tank No. 3, and the solid after centrifugation is sent to the drying device for drying into finished aluminum powder. Subsequently, the liquids in storage tanks No. 1, No. 2 and No. 3 are sent to the distillation reaction device, and after distillation at three different temperatures, solutions with three different boiling points are recovered respectively, finally producing finished wire drawing oil.

[0035] The specific usage process of the centrifugal processing device is as follows:

[0036] The mixture of aluminum sludge and oil can be fed into the separator cylinder 2 through the oil inlet pipe 7. Then, the first motor 3 is started to drive the drive gear 4 to rotate, which in turn drives the gear ring 5 and the separator cylinder 2 to rotate. This allows the aluminum sludge and oil in the separator cylinder 2 to be centrifugally separated. The waste oil can be discharged through the rotary joint 15 on the lower side and the oil outlet pipe 16. The aluminum sludge adheres to the inner wall of the separator cylinder 2. The second motor 6 drives the reciprocating screw 8 to rotate. The screw nut 20 moves up and down and moves through the connecting rod 14 to drive the conical scraper 13 to move, which can scrape and clean the aluminum sludge on the inner wall of the separator cylinder 2. This is the same as the device principle mentioned in the background technology of this article, so it will not be described in detail.

[0037] After the waste oil is drained, starting the second motor 6 drives the reciprocating screw 8 to rotate, causing the screw nut 20 to move up and down reciprocally, and driving the drive plate 21 to move up and down synchronously. During the movement of the drive plate 21, the transmission gear 23 in the transmission groove 22 will sequentially contact each limiting rack 19, and when the transmission gear 23 contacts a certain limiting rack 19, it can mesh with that limiting rack 19. Since the limiting rack 19 is fixed to the inner wall of the separation cylinder 2 by the support rod 18, the transmission gear 23 will be forced to rotate. When the transmission gear 23 rotates, it can drive the lifting rack 24 to move, and the lifting rack 24 will drive the piston plate 33 to move. When the transmission gear 23 leaves the limiting rack 19, the spring 26 can pull the piston plate 33 back to its original position. Therefore, as the drive plate 21 moves, the piston plate 33 will continuously move up and down as the transmission gear 23 passes through each limiting rack 19 in sequence.

[0038] When the piston plate 33 moves upward, the space below it increases, which generates negative pressure and draws the clean water in the water storage tank 9 into the pressure tank 25 through the drain pipe 11, corrugated pipe 12, water supply pipe 29 and water inlet pipe 28. After the piston plate 33 moves downward, the clean water in the pressure tank 25 can be discharged through the water outlet pipe 27 and used to rinse the inner wall of the separation cylinder 2. This greatly reduces the adhesion of the aluminum sludge, thereby reducing the resistance of the conical scraper 13 in removing the aluminum sludge, and also makes the aluminum sludge on the inner wall of the separation cylinder fall off faster and more thoroughly.

[0039] In addition, during the up-and-down movement of the piston plate 33, the pull rope 31 will also pull the water outlet pipe 27 to swing up and down, which increases the range of water flow discharged from the water outlet pipe 27 and thus accelerates the removal efficiency of aluminum sludge. The removed aluminum sludge can then be dried to remove moisture.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
