Description

Technical Field

[0001] This utility model relates to the field of decontamination devices, and in particular to a magnetic decontamination device for oil tanks. Background Technology

[0002] In a lubrication hydraulic system, the oil tank is a crucial component, typically the largest structural element. The tank stores the hydraulic fluid used during system operation. The fluid undergoes sedimentation, defoaming, and heat dissipation within the tank before flowing to the suction area, where it is pumped out and recycled. Oil tanks are generally divided into two interconnected areas: a return area and a suction area. During operation, the oil flowing back to the return area from the equipment contains significant heat, as well as substantial amounts of metallic impurities, moisture, and air bubbles. Efficiently and cost-effectively filtering these impurities from the return area is a pressing issue for all users.

[0003] Patent application CN216951046U discloses a hydraulic oil tank for a tunnel boring machine, including a tank body. The tank body is provided with an oil suction area and an oil return area. A drain valve is provided at the lower part of the tank body in the oil return area. A second baffle is provided in the oil return area. An overflow hole is opened on the second baffle. An oil-water separation area is formed between the second baffle and the inner wall of the tank body. A flow-blocking structure for reducing the oil flow rate is provided in the oil-water separation area. The flow-blocking structure is composed of several baffles arranged in parallel with each other. A bent meandering channel is formed between the baffles, the inner wall of the tank body, and the second baffle.

[0004] The existing technology device cannot remove impurities from the oil during use.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic decontamination device for oil tanks, which guides the flow path of oil and uses the physical adsorption of magnets to purify the oil, achieving a lossless oil purification effect.

[0007] The technical solution adopted in this utility model is: The oil tank magnetic suction cleaning device includes an oil return zone, an oil suction zone, and a cleaning structure located between the oil return zone and the oil suction zone within the oil tank. The cleaning structure includes a partition, a guide pipe, a magnetic rod, and an overflow plate. The overflow plate is vertically located in the middle of the oil tank, dividing the oil tank into the oil return zone and the oil suction zone. The partition is located within the oil return zone, and the guide pipe and magnetic rod are located between the partition and the overflow plate. Oil flows from the oil return zone into the guide pipe, flows in from the bottom of the guide pipe, flows out from the top, overflows from the overflow plate, and enters the oil suction zone.

[0008] By adopting the above structure, the oil flows from bottom to top in the oil tank. During this vertical flow, impurities and water are more likely to sink under the influence of gravity, and air is more likely to rise. The decontamination structure can effectively adsorb impurities in the oil passing around the magnetic rod. There are no consumable parts during use. The magnetic rod can be removed periodically to clean the impurities adsorbed on the outside. It can be used for a long time and is especially suitable for occasions with a lot of metal impurities.

[0009] Preferably, the baffle is located at the upper part of the oil return zone, and an upper mounting plate and a lower mounting plate for the guide pipe are provided horizontally between the baffle and the overflow plate. The guide pipe is located longitudinally between the baffle and the overflow plate and is fixed in position by the upper mounting plate and the lower mounting plate.

[0010] Preferably, the guide tube is a thin-edged cylindrical steel tube with a folded edge at the upper end. The folded edge is mounted on a mounting plate on the guide tube, and an overflow hole is opened on the upper circumferential direction of the guide tube.

[0011] Preferably, the bottom of the guide tube is fixed to the lower mounting plate of the guide tube, and a pressure cap is welded to the lower mounting plate of the guide tube. The pressure cap has a groove and a sealing ring is installed inside. The lower end of the guide tube passes through the pressure cap. The sealing ring inside the pressure cap seals and fixes the bottom end of the guide tube, ensuring that the oil flows in only from the inside of the guide tube.

[0012] By adopting the above structure, a guide pipe assembly is set between the oil return zone and the oil suction zone, which facilitates the flow of oil from the oil return zone into the oil suction zone. The guide pipe is fixed by the upper and lower mounting plates of the guide pipe, making the device structure more stable. The sealing structure at the bottom ensures that the oil flows in only from the inside of the guide pipe for magnetic suction cleaning.

[0013] Preferably, the magnetic rod is a hollow round steel tube, one end of which is sealed with a round end cap, and the other end is equipped with a connecting seat. The connecting seat is equipped with a handle for easy installation, maintenance and repair. The connecting seat is installed on the top of the guide tube, and a gap is left between the connecting seat and the guide tube to facilitate the escape of air in the oil in the guide tube.

[0014] Preferably, the cylindrical steel tube of the magnetic rod is filled with one cylindrical magnet block and one cylindrical rubber rod alternately, isolating each magnet block so that the magnetic fields do not cancel each other out and can make full use of the magnetic field of each magnet block. In this way, each magnet block forms an effective adsorption magnetic field through the cylindrical steel tube, which can effectively adsorb impurities in the oil passing by the magnetic rod.

[0015] By adopting the above structure, the internal structure of the magnetic rod prevents the magnets from attracting each other and the magnetic fields from canceling each other out, making it easy to install. It also makes full use of the magnetic field of each magnet, effectively adsorbing and removing impurities in the oil passing around the magnetic rod.

[0016] Preferably, the oil tank is provided with an oil suction port in the oil suction area and an oil return port in the oil return area. An overflow hole is opened on the upper part of the overflow plate. The height of the overflow hole is lower than that of the oil return port. Under the action of gravity, the oil can flow through the overflow hole to the oil suction area outside the overflow plate.

[0017] Preferably, the oil outlet of the return oil pipe extends into the bottom of the oil tank, and the end of the oil outlet is at a 45° bevel to increase the flow area, so that the return oil flows along the end of the return oil pipe into the lower layer of the oil, eliminating the impact and agitation with the liquid surface and reducing the air content in the oil.

[0018] By adopting the above structure, the oil flows from bottom to top in the oil tank through the forced flow of the structural components. During this vertical flow process, impurities and water are more likely to sink under the action of gravity, and air is more likely to overflow upwards. The air is discharged through the gap between the magnetic rod connector and the guide pipe.

[0019] Preferably, an inclined baffle is provided outside the overflow plate in the oil suction area. The inclined baffle is arranged opposite to the overflow hole, and the distance between the baffle and the overflow plate increases from bottom to top. The inclined baffle can guide the oil flowing out of the overflow hole to the bottom of the oil tank.

[0020] By adopting the above structure, when in use, hot oil flows to the bottom and then slowly rises as it flows towards the oil suction port of the oil tank. At this time, it will be fully mixed with the oil in the suction area and finally extracted for recycling.

[0021] Compared with the prior art, this utility model has the following advantages: 1. In the oil return zone of the oil tank, the device of this utility model uses the forced flow of the structural components to make the oil flow from bottom to top in the oil tank. During this vertical flow process, impurities and water are more likely to sink under the action of gravity, and air is more likely to overflow upwards. The air is discharged through the gap between the magnetic rod connecting seat and the guide pipe. In the oil suction zone of the oil tank, the inclined baffle of the structural components forces the return oil with high temperature to flow to the lower layer of the suction zone. Then, it makes full use of the physical law that hot oil rises and cold oil falls, so that the oil in the oil suction zone of the oil tank is more fully and evenly mixed.

[0022] 2. The length and number of the magnetic rod and the guide tube in this utility model device can be freely customized according to the specifications of the oil tank and the amount of impurities in the returned oil. It is suitable for various on-site working conditions, is easy to use, and the space between the guide tube and the magnetic rod is small and the flow is long, making full use of the length of the guide tube and the magnetic adsorption effect is better.

[0023] 3. The device of this utility model has magnetic blocks and rubber rods alternately filling the inside of the magnetic rod, preventing the magnetic blocks from attracting each other and the magnetic fields from canceling each other out. It is easy to install and makes full use of the magnetic field of each magnet. There are no consumable parts during use. The magnetic rod can be removed periodically to clean the impurities attracted on the outside. It can be used for a long time and is especially suitable for occasions with a lot of metal impurities.

Detailed Implementation

[0026] like Figure 1-7As shown, the magnetic suction cleaning device for the oil tank includes an oil return zone 21 and an oil suction zone 22 located within the oil tank 1, as well as a cleaning structure located between the oil return zone 21 and the oil suction zone 22. The cleaning structure includes a partition 3, a guide pipe 10, a magnetic rod 11, and an overflow plate 4. The overflow plate 4 is vertically positioned in the middle of the oil tank 1, dividing the oil tank 1 into the oil return zone 21 and the oil suction zone 22. The partition 3 is located within the oil return zone 21, and the guide pipe 10 and the magnetic rod 11 are located between the partition 3 and the overflow plate 4. Oil flows from the oil return zone 21 into the guide pipe 10, flows in from the bottom of the guide pipe 10, flows out from the top, overflows from the overflow plate 4, and enters the oil suction zone 22. An inclined baffle 7 is provided outside the overflow plate 4 in the oil suction zone 22. The inclined baffle 7 is positioned opposite the overflow hole 5, and the distance between the inclined baffle 7 and the overflow plate 4 increases from bottom to top. The inclined baffle 7 can guide the oil flowing out of the overflow hole 5 to the bottom of the oil tank 1. In the return oil zone 21 of oil tank 1, the oil flows from bottom to top in oil tank 1 through the forced flow of the structural components. During this vertical flow process, impurities and water are more likely to sink under the action of gravity, and air is more likely to overflow upwards. The air is discharged through the gap between the magnetic rod connector and the guide pipe. In the suction oil zone 22 of oil tank 1, the high-temperature return oil is forced to flow to the lower layer of the suction oil zone through the forced flow of the structural component inclined baffle 7. Then, the physical law of hot oil rising and cold oil falling is fully utilized to make the oil in the suction oil zone 22 of oil tank more fully and evenly mixed.

[0027] A baffle 3 is located at the top of the oil return zone 21. A guide pipe upper mounting plate 8 and a guide pipe lower mounting plate 9 are horizontally positioned between the baffle 3 and the overflow plate 4. A guide pipe 10 is longitudinally positioned between the baffle 3 and the overflow plate 4, and its position is fixed by the guide pipe upper mounting plate 8 and the guide pipe lower mounting plate 9. The guide pipe 10 is a thin-edged cylindrical steel pipe with a folded edge at its upper end, which is mounted on the guide pipe upper mounting plate 8. An overflow hole 23 is opened on the upper circumference of the guide pipe 10. The bottom of the guide pipe 10 is fixed to the guide pipe lower mounting plate 9. A pressure cap 12 is welded to the guide pipe lower mounting plate 9. A groove is opened inside the pressure cap 12, and a sealing ring 13 is installed therein. The lower end of the guide pipe 10 passes through the pressure cap 12. The sealing ring 13 inside the pressure cap 12 seals and fixes the bottom end of the guide pipe 10, ensuring that oil flows in only from the inside of the guide pipe 10. A guide pipe assembly is installed between the return oil zone 21 and the suction oil zone 22 to facilitate the flow of oil from the return oil zone into the suction oil zone. The guide pipe 10 is fixed by the upper mounting plate 8 and the lower mounting plate 9 of the guide pipe, making the device structure more stable. The sealing structure at the bottom ensures that the oil flows in only from the inside of the guide pipe 10 for magnetic suction cleaning.

[0028] The magnetic rod 11 is a hollow round steel tube 15, with one end sealed by a round end cap 14 and the other end fitted with a connecting seat 18. The connecting seat 18 has a handle 19 for easy installation, maintenance, and repair. The connecting seat 18 is installed at the top of the guide tube 10, with a gap between it and the guide tube 10 to allow air in the oil to escape. Inside the round steel tube 15 of the magnetic rod 11, a cylindrical magnet block 16 and a cylindrical rubber rod 17 are alternately filled, isolating each magnet block and preventing their magnetic fields from canceling each other out. This also fully utilizes the magnetic field of each magnet block. Thus, each magnet block, passing through the round steel tube 15, forms an effective adsorption magnetic field, effectively adsorbing impurities in the oil passing around the magnetic rod. The internal structure of the magnetic rod 11 prevents the magnet blocks from adsorbing each other and their magnetic fields from canceling each other out, facilitating installation and fully utilizing the magnetic field of each magnet to effectively adsorb and remove impurities in the oil passing around the magnetic rod 11.

[0029] The oil tank 1 has an oil suction port 20 in the oil suction zone 22 and an oil return port 6 in the oil return zone 21. An overflow hole 5 is opened on the upper part of the overflow plate 4. The height of the overflow hole 5 is lower than the oil return port 6. Under gravity, the oil can flow through the overflow hole 5 to the oil suction zone 20 outside the overflow plate 4. The oil outlet end of the oil return pipe 2 extends into the bottom of the oil tank 1. The end of the oil outlet end is at a 45° angle to increase the flow area, allowing the returned oil to flow along the end of the oil return pipe 2 into the lower layer of the oil, preventing impact and agitation with the liquid surface and reducing the air content in the oil. Through the forced flow of the structural components, the oil flows from bottom to top in the oil tank 1. During this vertical flow process, impurities and water are more likely to sink under gravity, while air is more likely to overflow upwards. The air is discharged through the gap between the magnetic rod connector and the guide pipe.

[0030] When this device is in use, the oil enters the return oil zone 21 from the return oil pipe 2 and flows in from the inside of the guide pipe 10, flowing from bottom to top. During this vertical flow, the oil passes through the magnetic rod 11, which adsorbs and removes impurities in the oil. Air can more easily overflow upwards and is discharged through the gap between the magnetic rod connecting seat 18 and the guide pipe 10. The oil flows through the overflow hole 5 at the top of the overflow plate 4 to the oil suction zone 20 of the oil tank. The oil flowing out of the overflow hole 5 is guided to the bottom of the oil tank 1 by the inclined baffle 7. Because the return oil generally carries a lot of heat, the temperature will be high. When the hot oil flows to the bottom and then flows towards the oil suction port of the oil tank, it will rise slowly. At this time, it will be fully mixed with the oil in the oil suction zone and finally extracted for recycling. The device can effectively filter, precipitate, separate oil and water, and remove impurities from the oil.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should be included within the scope of protection defined by the claims of the present utility model.
