[0001] The present application relates to the technical field of hydraulic oil tanks, in particular to a hydraulic oil tank with heat absorption and energy storage. BACKGROUND

[0002] The hydraulic oil tank refers to a container for storing oil required for the operation of the hydraulic system. During the operation of the hydraulic system, heat is generated, causing the oil temperature to rise. In some industrial production equipment, a hydraulic oil tank is used. The oil temperature in the tank is always above 60-70 DEG C, which may accelerate the aging of the oil and damage the seals. The existing hydraulic oil tank has a fixed heat absorption pipeline in the tank, which cannot stir the oil, is not conducive to rapid heat exchange, and cannot prolong the time of the air suction pipeline in the tank, which is not conducive to heat exchange and is inconvenient to use.

The outlet pipe is fixedly connected with the heat preservation tank at the end away from the annular cooling plate. This technical solution also has the technical problems mentioned above. SUMMARY

[0004] The present application aims to provide a hydraulic oil tank with heat absorption and energy storage to solve the problems mentioned in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a hydraulic oil tank with heat absorption and energy storage, comprising an oil tank body, a return oil pipe and an oil outlet pipe connected to the oil tank body, a circular shell fixedly arranged in the oil tank body, a rotating block rotatably arranged in the circular shell, a plurality of water containing cavities opened on the side surface of the rotating block, a water containing pipe fixedly and communicatively connected to the position corresponding to the water containing cavity on the top of the rotating block, and a water body contained in the water containing pipe. The water containing pipe moves in the oil body when the rotating block rotates.

[0006] Optionally, a support ring is fixedly connected to the oil tank body, and the top of the support ring is fixedly connected with the bottom of the circular shell.

[0007] Optionally, a circular plate is fixedly connected to the inner wall of the circular shell, a rotating shaft is rotatably connected to the circular plate, a center block is fixedly connected to the top of the rotating shaft, and the outer side of the center block is fixedly connected with the rotating block.

[0008] Optionally, a partition plate one is fixedly connected to the inner wall of the water-containing pipe, and a partition plate two is fixedly connected to the water-containing cavity. There is a gap between the top of the partition plate one and the top of the inner wall of the water-containing pipe.

[0009] Optionally, an exhaust pipe is fixedly connected to the rotating block, the exhaust pipe passes through the central block and the rotating shaft in sequence and extends to the outside of the oil tank body, and an exhaust valve is provided on the exhaust pipe.

[0010] Optionally, a drain pipe and a water inlet pipe are fixedly connected to the circular shell, with the end of the water inlet pipe extending to the outside of the oil tank body.

[0011] Optionally, a pressure shell is fixedly installed on the side of the main body of the oil tank, a hydraulic cylinder is installed on the top of the pressure shell, a piston plate is fixedly connected to the output shaft at the bottom of the hydraulic cylinder, the bottom of the pressure shell is connected to the water inlet pipe through a connecting pipe, and a control valve is installed on the connecting pipe.

[0012] Optionally, a recovery box is fixedly connected to the side of the oil tank body corresponding to the drain pipe, and the end of the drain pipe extends into the interior of the recovery box.

[0013] Optionally, a water supply pipe is fixedly connected to the side of the pressure shell, and an opening and closing cover is threaded onto the water supply pipe.

[0014] Optionally, the top of the recycling bin is provided with air vents.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes the coordinated operation of the oil tank body, return oil pipe, outlet oil pipe, circular shell, rotating block, water-containing cavity, water-containing pipe, support ring, circular plate, rotating shaft, and central block. During use, the water-containing cavity and water-containing pipe contain water. The water absorbs heat from the hydraulic oil in the tank, ensuring the oil maintains its optimal operating temperature. The water absorbs heat and heats up, allowing for heat storage. This heat can also be directly utilized later, recovering the heat generated by the hydraulic tank and saving energy. Furthermore, the rotating water-containing pipe inside the tank agitates the water, accelerating the heat exchange process between the oil and water. This results in high efficiency and ease of use.

[0016] This invention utilizes the cooperation of partition plate one, partition plate two, exhaust pipe and exhaust valve to allow water to rise to a relatively high height within the water-holding pipe during use by venting gas inside the pipe. The water-holding pipe can hold a larger volume of water, which is more conducive to absorbing the heat generated by the oil during operation.

[0017] This invention utilizes the interplay of a drain pipe, inlet pipe, pressure shell, hydraulic cylinder, piston plate, connecting pipe, control valve, recovery tank, water replenishment pipe, opening and closing cover, and air vent. During operation, the hydraulic cylinder intermittently drives the piston plate downwards, thus allowing water to flow intermittently into the cylindrical shell via the inlet pipe. This water flow is achieved through the operation of the hydraulic cylinder. The continuous flow of water into the water-containing chamber increases the pressure, causing the rotating block to rotate. The rotation of the rotating block is also due to the water flow, reducing the need for a drive mechanism and saving costs. Furthermore, because the water flow into the cylindrical shell is intermittent, the rotation of the water-containing pipe is also intermittent, rotating intermittently or stopping briefly. This extends the time the water remains in the hydraulic tank, allowing for effective heat exchange.

[0018] This invention, through the cooperation of a controller, sensor, slot ring, positioning shaft, locking block, fixing plate, mating block, and spring, automates the replacement of the entire device during use. The sensor monitors the water temperature in real time, which can prevent the water from absorbing too much oil temperature, resulting in the oil temperature being too low. It also limits the rotation direction of the rotating block, effectively preventing the rotating block from rotating in the opposite direction, making it convenient to use.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-12 A hydraulic oil tank with heat absorption and energy storage includes a tank body 1, with four mounting feet fixedly welded to its bottom. Each foot has a round hole, which allows mounting bolts to pass through the foot, thereby installing the tank body 1 into the working position. The tank body 1 is a hollow box, with a return oil pipe 2 fixedly connected to the upper left side and an oil outlet pipe 3 fixedly connected to the right bottom side. An oil injection pipe is also fixedly connected to the top of the tank body 1, through which oil can be injected into the tank body 1. A sealing cap is threaded onto the oil injection pipe. Rotating the sealing cap will disengage it from the oil injection pipe. A controller 27 is installed on the top of the tank body 1. The controller 27 is a PLC controller, model Siemens S7-1200.

[0023] The bottom of the fuel tank body 1 has a circular opening, and a support ring 8 is fixedly connected inside the circular opening. The support ring 8 is a circular ring that is open at both ends, and a circular shell 4 is fixedly connected to its top. The circular shell 4 is a shell with an open top and is located inside the fuel tank body 1. A circular plate 9 is fixedly connected to the inner wall of the circular shell 4, dividing the circular shell 4 into upper and lower parts. A bearing 35 is installed in a groove at the top of the circular plate 9, and a rotating shaft 10 is installed on the inner wall of the bearing 35. The inner and outer rings of the bearing 35 can rotate relative to each other. The surface of the outer ring is fixedly connected to the circular plate 9, and the inner wall of the inner ring is fixedly connected to the surface of the rotating shaft 10. The circular plate 9 and the bearing 35 support the rotating shaft 10, allowing the rotating shaft 10 to rotate without falling down. The rotating shaft 10 can rotate relative to the circular plate 9 but will not detach from the circular plate 9. A center block 11 is fixedly connected to the top of the rotating shaft 10. The center block 11 is a disc-shaped structure. A rotating block 5 is fixedly connected to the side. Due to the structure of the rotating shaft 10 and the circular plate 9, the rotating block 5 can rotate inside the circular shell 4. Both the upper and lower sides of the rotating block 5 are machined with annular recesses. A second sealing ring 39 is glued to the bottom annular recess, and a first sealing ring 38 is glued to the top annular recess. Both the first sealing ring 38 and the second sealing ring 39 are made of silicone rubber. The horizontal plane away from the rotating block 5 is in close contact with the inner wall of the circular shell 4, and the annular side is in close contact with the inner wall of the circular shell 4. In practice, the diameter of the first sealing ring 38 and the second sealing ring 39 is slightly larger than the inner diameter of the circular shell 4. This is to make the first sealing ring 38 and the second sealing ring 39 squeezed by the inner wall of the circular shell 4, so as to achieve a good sealing effect. The setting of the first sealing ring 38 and the second sealing ring 39 is also to provide greater friction, so that the rotating block 5 will not easily rotate inside the circular shell 4.

[0024] The rotating block 5 is located inside the circular shell 4, and six water-containing cavities 6 are formed on it. The edges of the rotating block 5 corresponding to the water-containing cavities 6 are relatively narrow. The water-containing cavities 6 constitute the water outlet. When external water enters the circular shell 4, it will enter the water-containing cavities 6. The top of the rotating block 5 is also fixedly connected to six water-containing pipes 7. The water-containing pipe 7 is a pipe with a closed top and an open bottom. Its bottom opening is connected to the water-containing cavities 6. The water-containing pipes 7 also constitute a water-containing space. It is filled with water and is located inside the oil tank body 1. It can absorb the temperature of the oil in the oil tank body 1 and raise its temperature. The rotating block 5 can rotate inside the circular shell 4. Therefore, when a force drives the rotating block 5 to rotate, the water-containing pipes 7 will also move inside the oil tank body 1. This stirs the oil and facilitates heat exchange between the oil and the water.

[0025] A pressure shell 18 is fixedly connected to the right side of the main body 1 of the oil tank. A hydraulic cylinder 19 is installed on the top of the pressure shell 18. The output shaft at the bottom of the hydraulic cylinder 19 passes through the interior of the pressure shell 18 and is fixedly connected to a piston plate 20. A sealing gasket 37 is fixedly connected to both the top and bottom of the piston plate 20. The sealing gasket 37 is made of halogenated butyl rubber. The horizontal cross-section of the sealing gasket 37 is slightly larger than the horizontal cross-section of the inner wall of the pressure shell 18. The purpose of this design is to ensure that the sealing gasket 37 is compressed by the inner wall of the pressure shell 18 when it is inside the pressure shell 18, thus achieving a good sealing purpose. A water supply pipe 24 is fixedly connected to the side of the pressure shell 18. The water supply pipe 24 is used to pre-fill the pressure shell 18 with water. An opening and closing cover 25 is also threaded onto the water supply pipe 24. After tightening the opening and closing cover 25, the hydraulic cylinder 19 drives the piston plate 20 to move downward. Water will not overflow from the water supply pipe 24. The bottom of the pressure shell 18 is fixedly connected to the connecting pipe 21, and a control valve 22 is installed on the connecting pipe 21. When the control valve 22 is closed, the connecting pipe 21 will not flow water downward. The bottom end of the connecting pipe 21 is fixedly connected to the water inlet pipe 17. One end of the water inlet pipe 17 passes through the oil tank body 1 and is fixedly connected to the circular shell 4. When the control valve 22 is opened, the hydraulic cylinder 19 drives the piston plate 20 to move downward, and the water will enter the circular shell 4 through the water inlet pipe 17. The water inlet pipe 17 is offset from the left and right center lines of the rotating block 5. The water discharged from the port of the water inlet pipe 17 will enter the water chamber 6 and then enter the water inlet pipe 7. When the water gradually flows into the circular shell 4 and reaches the predetermined value, the water pressure can overcome the friction generated by the compression of the sealing ring 1 38 and the sealing ring 2 39, so that the rotating block 5 rotates in the circular shell 4, and the water inlet pipe 7 will stir the oil.

[0026] To allow water to drain from the cylindrical shell 4, a drain pipe 16 with openings on both sides is fixedly connected to the cylindrical shell 4. A recovery tank 23 is fixedly connected to the side of the fuel tank body 1 corresponding to the position of the drain pipe 16. The end of the drain pipe 16 away from the cylindrical shell 4 extends out of the fuel tank body 1 and into the interior of the recovery tank 23, thus providing an outlet for the water. After heat exchange between the water and oil in the fuel tank body 1, the heated water enters the recovery tank 23 through the drain pipe 16. To ensure smooth water flow, an air vent 26 is provided at the top of the recovery tank 23 to prevent excessive pressure inside the recovery tank 23 from hindering water entry. A pipe is connected to the bottom of the recovery tank 23. A valve is also installed on the channel. Opening the valve allows the hot water in the recovery tank 23 to be discharged for use elsewhere. This also allows for heat absorption and energy storage in the hydraulic oil tank, with the heat energy stored in the hot water. Furthermore, a water temperature sensor 28 is installed inside the recovery tank 23. The specific model of the sensor 28 is MC-850079. The sensor 28 detects the water temperature. When the water temperature is too high, it means that the oil temperature in the main body of the oil tank 1 is too high. In this case, the working frequency of the hydraulic cylinder 19 needs to be increased to speed up the injection of water into the cylindrical shell 4. When the water temperature is too low, it means that the water flow rate is too fast, and the water carries away too much heat from the oil. This may affect the normal operation of the main body of the oil tank 1, and in this case, the water flow rate needs to be reduced.

[0027] To address the issue of water pressure within the water-holding pipe 7, which causes air pressure to affect the water level and cause it to rise, each water-holding cavity 6 is fixedly connected to a partition plate 2 13. The partition plate 2 13, facing the side of the central block 11, forms an independent cavity with the rotating block 5, preventing direct water entry. A partition plate 12 is fixedly connected to the top of partition plate 2 13. Partition plate 12 is located inside the water-holding pipe 7, with a gap between its top and the top of the inner wall of the water-holding pipe 7. The side of partition plate 12 is fixedly connected to the inner wall of the water-holding pipe 7. Here, partition plate 12 serves to separate the space within the water-holding pipe 7. The rotating block 5 is fixedly connected to... Six exhaust pipes 14, one end of which passes through the central block 11 and the rotating shaft 10 in sequence, extending to the outside of the oil tank body 1. An exhaust valve 15 is provided on the exhaust pipe 14. The exhaust valve 15 is specifically a permeate membrane valve. The valve opening is adjusted to the critical point where gas can pass through and liquid is intercepted. This is the conventional use technology of permeate membrane valves and is existing technology. With the aforementioned structure, when water in the inlet pipe 17 enters the water-containing chamber 6, the water will gradually fill the water-containing chamber 6 and then rise along the closed water-containing pipe 7. Gas will be discharged through the exhaust pipe 14, but water will not be discharged. This ensures that the water-containing pipe 7 is full of water and is not affected by air pressure.

[0028] Control valve 22 is specifically an electrically controlled valve, electrically driven to open and close. It is electrically connected to controller 27, which controls the opening and closing of control valve 22. Hydraulic cylinder 19 is electrically connected to controller 27. Controller 27 has basic editing functions, allowing settings to be configured for how often hydraulic cylinder 19 operates and for how long each operation lasts. For example, hydraulic cylinder 19 can operate for 10 seconds at a time, with a two-minute interval between operations. Control valve 22 operates synchronously with hydraulic cylinder 19, as water can only enter the inlet pipe 17 through connecting pipe 21 when control valve 22 is open. The operating time and interval of hydraulic cylinder 19 are preset, as sensor 28 also... The water temperature is monitored in real time, so the operation needs to be flexibly adjusted according to the settings of the controller 27. When the water in the pressure shell 18 is used up, the control valve 22 is closed, the opening and closing cover 25 on the water supply pipe 24 is removed, and then the hydraulic cylinder 19 drives the piston plate 20 to move upward. Water is injected again when the piston plate 20 is higher than the water supply pipe 24. Note that when injecting water into the pressure shell 18 at this time, the air pressure problem also needs to be considered. Therefore, when injecting water into the pressure shell 18 through the water supply pipe 24, a flexible hose thinner than the water supply pipe 24 needs to be inserted into the pressure shell 18. This leaves space for the air to be discharged from the water supply pipe 24, and the water injection work of the thin hose can be carried out continuously without causing the air in the pressure shell 18 to be unable to be discharged.

[0029] To limit the rotation direction of the rotating block 5, this technical solution includes a positioning shaft 30 fixedly connected to the bottom of the oil tank body 1. The positioning shaft 30 is a cylindrical shaft with a locking block 31 rotatably connected to its surface. A retaining ring 29 is fixedly connected to the surface of each of the six exhaust pipes 14. The retaining ring 29 has several slots on its side, and the sharp end of the locking block 31 fits precisely into one of these slots. The teeth on the surface of the retaining ring 29 and the shape of the locking block 31 limit the rotation direction of the six exhaust pipes 14, thus limiting the rotation direction of the rotating block 5. Figure 1 From a top-down view, the rotating block 5 can only rotate counterclockwise. A fixed plate 32 is also fixedly connected to the bottom of the tank body 1. The side of the fixed plate 32 is connected to a mating block 33 via a spring 34. The mating block 33 is fixedly connected to the locking block 31. The spring 34 is in a compressed state as shown in the figure, so the spring 34 has a tendency to return to its original length. The squeezing force of the spring 34 returning to its original length will push the locking block 31 through the mating block 33, preventing the sharp end of the locking block 31 from disengaging from the slot. When the rotating block 5 rotates due to water pressure, the locking teeth on the slot ring 29 will squeeze the locking block 31, and the spring 34 will shorten again.

[0030] Finally, all valves used in this technical solution are electrically driven valves, which do not require manual operation by personnel. Furthermore, the rotating block 5, the round shell 4, and the water pipe 7 in this technical solution are all made of metals with good thermal conductivity, including aluminum alloys in the prior art, which have both excellent thermal conductivity and high strength.

[0031] During use, the pressure shell 18 is pre-filled with water. The controller 27 controls the hydraulic cylinder 19 to work, and the control valve 22 opens. The hydraulic cylinder 19 drives the piston plate 20 to move downward, squeezing the water in the pressure shell 18. The water enters the circular shell 4 through the connecting pipe 21 and the inlet pipe 17, flows into the water chamber 6, and then rises along the water pipe 7. The gas in the water pipe 7 is discharged through the exhaust pipe 14. The exhaust valve 15 can block the water and discharge the gas. The circular shell 4 and the water pipe 7 are both inside the oil tank body 1. The oil will cause the water to heat up. The hydraulic cylinder 19 works intermittently, as previously explained. When the hydraulic cylinder 19 works again, the corresponding... When both the water-containing chamber 6 and the water-containing pipe 7 are filled with water, the increased water pressure overcomes the friction generated by the sealing rings 38 and 39, causing the rotating block 5 to rotate inside the circular shell 4. This causes the water-containing pipe 7 to rotate as well, stirring the oil and ensuring a uniform oil temperature within the main body of the oil tank 1. This prevents the oil temperature near the circular shell 4 and the water-containing pipe 7 from dropping too quickly. As the rotating block 5 continues to rotate, when the water-containing chamber 6, which contains water, aligns with the drain pipe 16, the water is discharged into the recovery tank 23 through the drain pipe 16. This intermittent water flow allows the water-containing pipe 7 to rotate intermittently, extending the time the water remains inside the main body of the oil tank 1.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
