Description

Technical Field

[0001] The invention relates to the technical field of distillation and concentration, and in particular to a temporary oil storage device for recycling drawing oil. Background Art

[0002] The wire drawing process in enameled wire production requires lubrication and cooling of the drawing fluid. The drawing fluid consists of drawing oil and water, with the drawing oil content of about 5-10%. In order to avoid wasting resources, factories usually use distillation to obtain high-purity drawing oil from the drawing fluid, and use a distillation concentrator to separate the drawing oil and water. The drawing oil separated after distillation is put into a crude oil barrel placed on a forklift pallet (due to the large amount of drawing fluid used and to avoid frequent transportation, a large-capacity crude oil barrel with a large footprint is selected. Generally, it can hold about 3 tons of drawing oil at a time, and the crude oil barrel is generally placed towards the factory door opening to facilitate the forklift to directly fork out the crude oil barrel). When the oil in the crude oil barrel is full or the drawing oil is needed, it is necessary to use a forklift to transport the crude oil barrel.

[0003] When the crude oil barrel is full of oil, the operator usually stops the distillation concentrator first (the purpose of stopping is to prevent oil from overflowing from the pipe mouth during the subsequent disassembly and installation of the hose, resulting in oil waste), then removes the hose connecting the distillation concentrator and the crude oil barrel, and then uses a sealing cap to seal the oil inlet of the crude oil barrel. After using a forklift to pull the crude oil barrel out of the factory, the worker promptly replaces the empty crude oil barrel and the forklift pallet that matches it in its original place, and then screws one end of the hose to the oil inlet of the crude oil barrel, and then starts the distillation concentrator to perform separation. During this process, The need to stop the operation of the distillation concentrator will result in the distillation concentrator being unable to perform continuous distillation operations, affecting the working efficiency of the distillation concentrator. At the same time, personnel manually disassemble and install the hoses and crude oil barrels, which is troublesome and labor-intensive. In addition, the empty crude oil barrels are often not placed in time (for example, if the crude oil barrels are found to be damaged and need to be replaced, and the new crude oil barrels are some distance away from the factory, it takes some time to go back and forth to get the barrels). This will greatly extend the stop time of the distillation concentrator and further reduce the working efficiency. Therefore, the present application provides a temporary oil storage device for the recycling of drawing oil to meet the needs. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example: Reference Figure 1-7The temporary oil storage device for wire drawing oil recycling shown in the figure comprises a distillation concentrator 1, a crude oil barrel 2 placed on a forklift pallet and provided with an oil inlet hole at the upper end, a driving unit 4 for driving the temporary oil storage barrel 3 to move in an L-shaped path and finally connect the oil outlet pipe of the temporary oil storage barrel 3 with the oil inlet hole, and an opening and closing unit 7 installed on the temporary oil storage barrel 3 and used for automatically opening and closing the oil outlet pipe of the temporary oil storage barrel 3. The driving unit 4 is installed on the side end of the distillation concentrator 1, and the temporary oil storage barrel 3 is provided with an oil inlet pipe 5, and the oil inlet pipe 5 is connected to the oil outlet pipe 5 through a hose. The oil outlet end of the distillation concentrator 1 is connected, and the outer surface of the oil outlet pipe of the temporary oil storage barrel 3 is provided with a first elastic sealing sleeve 10 that can seal the oil inlet hole. The lower end of the oil outlet pipe is tapered. When in use, the temporary oil storage barrel 3 can be driven by the driving unit 4 to make an L-shaped path movement, that is, first a horizontal linear movement is performed to move the oil outlet pipe of the temporary oil storage barrel 3 to just above the oil inlet hole of the crude oil barrel 2, and then the temporary oil storage barrel 3 is driven downward to connect the oil outlet pipe with the oil inlet hole. After the installation is completed, the opening and closing unit 7 automatically opens the oil outlet pipe at the same time. The wire drawing oil temporarily stored in the temporary oil storage barrel 3 can enter the crude oil barrel 2 through the oil outlet pipe. When the crude oil barrel 2 needs to be replaced, the temporary oil storage barrel 3 can be controlled by the driving unit 4 to move in the opposite direction, that is, the temporary oil storage barrel 3 is first controlled to move straight upward to move the oil outlet pipe out of the oil inlet hole. At the same time, the opening and closing unit 7 automatically closes the oil outlet pipe and no longer discharges oil. At this time, the temporary oil storage barrel 3 is used as a temporary oil storage device to store oil, and then it is used as a temporary oil storage barrel 3 to move horizontally and move back to its original position. The purpose of its horizontal movement is to move the temporary oil storage barrel 3 away so that It is not directly above the crude oil barrel 2, which can prevent the forklift operator from lifting the crude oil barrel too high due to improper operation, causing it to collide with the temporary oil storage barrel 3, and can effectively avoid damage to the crude oil barrel 2 or the temporary oil storage barrel 3 due to improper operation. When replacing the crude oil barrel 2, its temporary oil storage barrel 3 can be used as a temporary oil storage device to store oil to meet the continuous operation requirements of the distillation concentrator 1, and can automatically complete the docking of the oil outlet pipe and the oil inlet hole, without the need for manual docking with the crude oil barrel 2 using a hose, making the operation more convenient and simple with low labor intensity.

[0036] It should be noted that, first, the oil inlet is sealed by the first elastic sealing sleeve 10 to prevent dust and other impurities from entering the barrel through the gap between the oil outlet pipe and the oil inlet and contaminating the internal drawing oil; second, the conical setting of the lower end of the oil outlet pipe is conducive to the guided connection between the oil outlet pipe and the oil inlet; third, the drive motor 46 is electrically connected to the programmable PLC controller installed on the outer wall of the U-shaped shell 41.

[0037] As a preferred implementation in this embodiment, Figure 1-4As shown, the drive unit 4 includes a U-shaped shell 41 installed on the upper side end of the distillation concentrator 1, and the inner cavity of the U-shaped shell 41 is provided with a U-shaped plate 42 with sliders 45 installed on both sides. The two sliders 45 are slidably arranged in a slide groove opened on the inner cavity wall of the U-shaped shell 41. The upper end of the U-shaped plate 42 is fixed with a threaded tube 43 threadedly sleeved on the screw 44. The screw 44 is rotated in the inner cavity of the U-shaped shell 41. The power input end of the screw 44 is fixed to the outer wall of the U-shaped shell 41. The output shaft of the driving motor 46 on the upper part is fixedly connected, and the lower end of the U-shaped plate 42 is provided with two side plates 47, and two movable rods 410 are provided between the two side plates 47 through the rotating shaft. The upper ends of the two movable rods 410 are rotatably connected to the U-shaped plate 42 through the rotating shaft. A fixed I-shaped mounting plate 48 is provided between the two side plates 47, and the lower end of the I-shaped mounting plate 48 is fixedly connected to the temporary oil storage barrel 3 through the mounting bracket 6. The lower end of the U-shaped shell 41 is relatively fixed with two L-shaped baffles 49, and the two side plates 47 are relatively fixed. The left and right ends of the opening and closing unit 7 are respectively in sliding contact with the corresponding lateral edges of the L-shaped baffle 49 and the inner wall of the U-shaped shell 41; the opening and closing unit 7 includes a contact ring 71 slidably mounted on the oil outlet pipe, the outer wall of the contact ring 71 is fixedly connected to one end of the opening and closing rod 72, the other end of the opening and closing rod 72 passes through the temporary oil storage barrel 3 and extends to the inner cavity of the oil outlet pipe, a sealing ring is provided at the penetration point of the opening and closing rod 72 and the temporary oil storage barrel 3, and a mounting ring 73 is fixed to the upper end of the opening and closing rod 72, and the mounting ring 73 An opening and closing spring 74 is fixed between the bottom end and the upper end of the temporary oil storage barrel 3. A frustum-shaped sealing ring 75 is fixed on the opening and closing rod 72 located in the inner cavity of the temporary oil storage barrel 3, and the outer wall of the sealing ring 75 and the outer wall of the lower end of the opening and closing rod 72 located in the inner cavity of the oil outlet pipe are wrapped with a second elastic sealing sleeve 76. The sealing ring 75 is arranged just above the frustum-shaped oil inlet 8 of the oil outlet pipe, and the second elastic sealing sleeve 76 located below is located in the first annular flow channel 9 opened on the inner wall of the oil outlet pipe. Figure 1-7As shown, the opening and closing spring 74 in the figure is in a stretched state. When the crude oil barrel 2 needs to be replaced, the operator can manually control the drive motor 46 to rotate in the opposite direction through the PLC controller. The drive motor 46 drives the screw 44 to rotate in the opposite direction, and uses the threaded tube to drive the U-shaped plate 42 to move horizontally. At this time, since the two ends of the side plate 47 respectively slide against the corresponding lateral edges of the L-shaped baffle 49 and the inner wall of the U-shaped shell 41, the side plate 47 cannot move horizontally. The upward component force of the two sliding rods 410 can drive the two side plates 4 7 moves upward, and when the upper ends of the two side plates 47 just contact the lower ends of the U-shaped plate 42, the lower ends of the two side plates 47 just move to above the horizontal plate of the L-shaped baffle 49, and the upper end of the horizontal plate arranged below on the I-shaped mounting plate 48 just is located below the L-shaped baffle 48. Driven by the horizontal movement of the U-shaped plate 42, the horizontal plate of the L-shaped baffle 49 can be snapped into the gap between the lower end of the side plate 47 and the horizontal plate arranged below on the I-shaped mounting plate 48, so that the two side plates 47 slide linearly on the L-shaped baffle 49. During the whole process, The temporary oil storage barrel 3 can be driven by the mounting frame 6 to move upward linearly, and then driven to move horizontally linearly, that is, to move linearly along an L-shaped path, so as to release the connection between the oil outlet pipe and the oil inlet hole and move the temporary oil storage barrel 3 away from the top of the crude oil barrel 2. When the oil outlet pipe moves upward, its contact ring 71 moves downward along the oil outlet pipe through the action of the opening and closing spring 74, thereby driving the opening and closing rod 72 to move downward, and the frustum-shaped oil inlet 8 can be sealed by the cooperation of the sealing ring 75 and the second elastic sealing sleeve 76, so as to prevent further injection into the crude oil barrel 2. When the crude oil barrel 2 is replaced, the drive motor 46 can be controlled to rotate forward, driving the two side plates 47 to rotate horizontally. When the right ends of the two side plates 47 form a contact barrier with the inner wall of the U-shaped shell 41, the two side plates 47 will move vertically downward under the action of the two movable rods 410, thereby completing the docking of the oil outlet pipe and the oil inlet hole. During this process, the lower end of the contact ring 71 will contact and squeeze the upper end of the crude oil barrel, thereby causing the opening and closing rod 72 to stretch the opening and closing spring 74 and move upward. At this time, the flow channel of the oil outlet pipe is opened, as shown in FIG. Figure 7 As shown, the drawing oil in the temporary oil storage barrel 3 can be injected into the crude oil barrel 2 through this flow channel.

[0038] It should be noted that, first, after the lower end of the oil outlet pipe is inserted into the oil inlet hole, the oil outlet pipe continues to move downward, and only then will the contact ring 71 contact the upper end of the crude oil barrel 2; second, when the oil outlet pipe and the oil inlet hole are released from docking, the opening and closing rod 72 is located at the lower end of the inner cavity of the temporary oil storage barrel 3 and moves downward to seal the flow channel of the oil outlet pipe through the second elastic sealing sleeve 76 on its outer wall, so as to avoid the adsorption of dust and other impurities on the inner wall of the flow channel when the device is not in use, and to avoid contamination of the oil body during subsequent oil filling. Before using the device after a period of time, the oil outlet of the lower oil outlet pipe should be wiped with a cloth to remove dust and other impurities on the oil outlet.

[0039] As a preferred implementation in this embodiment, Figure 7 As shown, the inner cavity of the oil outlet pipe is provided with a vent cavity 12, which is used to keep the crude oil barrel 2 consistent with the external atmospheric pressure. Since the oil inlet and the oil outlet pipe are sealed by the first elastic sealing sleeve 10, as the liquid level in the crude oil barrel 2 continues to rise, the internal gas is compressed, which easily causes the internal air pressure to increase and affect the oil discharge speed of the oil outlet pipe. Therefore, the vent cavity 12 is provided to make the internal and external air pressure of the crude oil barrel 2 consistent, which is conducive to the smooth discharge of the oil in the temporary oil storage barrel 3.

[0040] In this embodiment, if Figure 7 and Figure 8 As shown, it also includes a filtering and sterilizing device 13 for preventing impurities from entering the inner cavity of the crude oil barrel 2 through the ventilation cavity 12. The filtering and sterilizing device 13 includes an air guide tube 131 that communicates with the inner cavity of the ventilation cavity 12, and the inner cavity of the air guide tube 131 is sequentially installed with a waterproof and breathable membrane layer 133 and a silver ion sterilizing net 132 from bottom to top. The lower end of the air guide tube 131 is threadedly installed with a mounting cover 134 with an annular air hole, which can prevent dust and bacteria from entering the crude oil barrel 2 through this ventilation cavity 12 and causing contamination of the internal oil. Furthermore, a drying layer can be provided between the waterproof and breathable membrane layer 133 and the silver ion sterilizing net 132. The drying layer is filled with desiccant particles, which can remove small particles of moisture in the humid air and prevent them from contacting the oil and affecting the concentration of the oil in the crude oil barrel 2.

[0041] It should be noted that a filtering and sterilizing device 13 communicating with the inner cavity of the temporary oil storage barrel 3 can also be provided at the upper end of the temporary oil storage barrel 3. The air duct 131 of the device is communicated with the inner cavity of the temporary oil storage barrel 3, so that the internal and external air pressures of the temporary oil storage barrel 3 can be made consistent, thereby avoiding affecting the downstream speed of the oil temporarily stored in the temporary oil storage barrel 3.

[0042] In this embodiment, if Figure 7 and Figure 9As shown, the inner cavity of the ventilation cavity 12 is provided with a second annular flow channel 14 and a third annular flow channel 15 at the upper and lower parts, and the second annular flow channel 14 and the third annular flow channel 15 are connected by a cavity 18. The inner cavity of the ventilation cavity 12 is provided with an L-shaped movable member 16 for sealing the ventilation cavity 12, and the upper and lower ends of the L-shaped movable member 16 are respectively located in the inner cavities of the second annular flow channel 14 and the third annular flow channel 15. The inner cavity of the contact ring 71 is installed with a permanent magnet 17 for driving the L-shaped movable member 16 to move up and down by magnetic force. The outer wall of the lower end of the L-shaped movable part 16 is wrapped with a third elastic sealing sleeve 19. The contact ring 71 can drive the permanent magnet 17 to move upward or downward. The permanent magnet 17 is used to drive the L-shaped movable part 16 to move upward or downward to make the ventilation cavity 12 form an on-off state. The third elastic sealing sleeve 19 can seal the lower opening of the ventilation cavity 12 to prevent dust and other impurities from entering the ventilation cavity 12 and causing blockage, or internal dust from falling into the crude oil barrel 2 during oil filling and causing oil contamination.

[0043] As a preferred implementation in this embodiment, Figure 9 As shown, the L-shaped movable member 16 includes a cylinder located in the ventilation cavity 12, the second annular flow channel 14 and the third annular flow channel 15, and a magnetic block 20 fixed on the cylinder. The right end of the magnetic block 20 is slidably set in a groove provided on the inner wall of the second annular flow channel 14. The magnetic block 20 is magnetically fixed to the permanent magnet 17. When the contact ring 71 moves upward under extrusion, the permanent magnet 17 can drive the cylinder to move upward through the magnetic block 22 through the magnetic effect, and finally form the following Figure 9 As shown, the ventilation cavity 12 is a passage that can keep the air pressure inside and outside the crude oil barrel 2 consistent when filling oil. When the contact ring 71 moves downward under the action of the opening and closing spring 74, the permanent magnet 17 drives the cylinder downward through the magnetic block 20, which can seal the lower opening of the ventilation cavity 12 to prevent contamination. The magnetic block 20 is slidably set in the groove to ensure that the magnetic block 20 does not rotate or deviate.

[0044] As a preferred implementation in this embodiment, Figure 1 As shown, it also includes a circular placement area 11 adapted to the forklift pallet. The upper end of the forklift pallet is provided with a placement groove adapted to the bottom of the crude oil barrel 2. When the forklift pallet is located in the circular placement area 11 and the crude oil barrel 2 is located at the lower end in the placement groove, the axis of the oil inlet hole of the crude oil barrel 2 and the axis of the downwardly moving oil outlet pipe are located on the same vertical straight line, which limits the placement position of the crude oil barrel 2 and facilitates the precise docking of the oil outlet pipe and the oil inlet hole.

[0045] It should be noted that the roundabout placement area 11 is formed by spraying paint on the ground.

[0046] As a preferred implementation in this embodiment, Figure 7As shown, a liquid level probe 23 is installed in the groove at the bottom of the oil outlet pipe, and a first contact switch 22 is fixed on the outer wall of the oil outlet pipe. The first contact switch 22 and the liquid level probe 23 are both electrically connected to the PLC controller provided on the drive unit 4. The drive unit 4 is also equipped with a first alarm electrically connected to the PLC controller. When the flow channel of the oil outlet pipe is open, the upper end of the contact ring 71 will contact the first contact switch 22. At this time, the liquid level probe 23 works to measure the liquid level in the barrel. When the liquid level probe 23 detects that the liquid level in the barrel reaches a programmed set value, the PLC controller controls the first alarm to sound an alarm to alert the staff. At the same time, the PLC controller controls the drive unit 4 to drive the oil outlet pipe to rise a certain distance (which can be programmed). The contact ring 71 moves downward under the elastic force of the opening and closing spring 74. At this time, the oil outlet pipe is still sealed with the oil inlet (to prevent contamination of the oil body), and the contact ring 71 does not contact the first contact switch 22. At this time, the liquid level probe 23 is powered off and does not work, which can achieve automatic power off and save energy.

[0047] It should be noted that the liquid level probe can be a radar level probe.

[0048] As a preferred implementation in this embodiment, Figure 6 As shown, a second contact switch 21 for controlling the working state of the distillation concentrator 1 is fixed to the top of the inner cavity of the temporary oil storage barrel 3, and the second contact switch 21 is electrically connected to the PLC controller.
