Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil storage, specifically a hydraulic oil storage device for machining centers. Background Technology

[0002] Hydraulic oil is an important driving medium in hydraulic equipment. When hydraulic oil is used, it can be stored in a storage device and connected to the hydraulic system through an oil delivery channel on the storage device to enable subsequent use of the hydraulic oil. For example, a hydraulic oil storage device with cooling function disclosed in application number 2021224967426 achieves heat dissipation of hydraulic oil in the tank through a heat dissipation mechanism. Compared with the existing heat dissipation mechanism, this heat dissipation mechanism achieves heat dissipation of hydraulic oil by using the flow of hydraulic oil as the driving force, which is more environmentally friendly and energy-saving.

[0003] However, during the use of the storage equipment, the hydraulic oil is continuously transported back and forth, and the oil body is also prone to carrying residues. The oil body then enters the storage equipment along with the residues and is then sent out again. The residues in the oil body before it is sent out cannot be filtered, which can easily have an adverse effect on the related hydraulic equipment and reduce its service life.

[0004] For example, a Chinese patent discloses a hydraulic oil storage device with a cooling function (authorization announcement number CN219258308U). This patented technology is equipped with an external extraction pipe, an internal delivery pipe, and a one-way conduction mechanism. The combination of the external extraction pipe and the internal delivery pipe with the one-way conduction mechanism allows the oil entering and exiting the storage tank to move along different pipelines. The filter plate installed in the external extraction pipe can effectively filter the delivered oil. Furthermore, the oil containing waste residue can enter the storage tank through the internal delivery pipe. The two do not affect each other, which can effectively prevent the repeated transportation of residue in the oil, which could cause pipeline blockage or damage to the hydraulic equipment.

[0005] Equipped with a heat-absorbing plate and heat sink, the heat-absorbing plate absorbs the heat from the oil in the storage tank, and then the heat is discharged from the storage tank through a heat-conducting rod. With the help of the heat sink, the heat can be quickly dissipated outward, thereby cooling the hydraulic oil in the storage tank and increasing its functionality.

[0006] However, it has certain drawbacks: during long-term operation, a large amount of dust and impurities will continue to accumulate on the surface of the heat sink. These contaminants accumulate on the surface of the heat sink to form a heat insulation layer, which seriously hinders the efficient transfer of heat to the air, resulting in a significant decrease in heat dissipation efficiency and affecting the cooling effect of hydraulic oil.

[0007] Therefore, this utility model provides a hydraulic oil storage device for machining centers. Utility Model Content

By setting up a pipe array that precisely corresponds to the gaps between heat sinks, each pipe can travel through all the gaps between heat sinks without dead angles under the drive of a telescopic cylinder.

In conjunction with the air inlet filter plate to block external contaminants, this design achieves efficient cleaning of the heat sinks while avoiding secondary pollution or system blockage during the blowing process, significantly improving the long-term stability and heat dissipation efficiency of the cooling system.

[0028] Please see Figures 1-3In this embodiment of the present invention, a hydraulic oil storage device for a machining center includes a storage box body 1 and a box cover 2 fixed to the upper end of the storage box body 1. A heat dissipation plate 3 is fixed to the upper surface of the box cover 2. Multiple heat dissipation fins 4 are evenly fixed to the upper surface of the heat dissipation plate 3 from left to right.

[0029] In this embodiment: the storage box body 1 and the box cover 2 are fixed together by bolts. A valve communicating with the inside is fixed to the lower end of the left side surface of the storage box body 1. The valve 10 is welded or flanged to the inside of the storage box body 1 near the lowest point of the bottom of the box body, and is used to completely drain the oil or take samples.

[0030] In this embodiment: the heat sink 4 is used to increase the contact area between the heat sink 3 and the air, thereby enhancing the convective heat dissipation effect.

[0031] Multiple support plates 9 are radially and uniformly welded to the lower surface of the support sleeve 6. They are used to absorb and conduct heat from the oil to the support sleeve 6, and then to the heat dissipation plate 3 via the support rod 8.

[0032] A rubber sealing sleeve can be fitted at the connection between the outside of the support rod 8 and the box cover 2;

[0033] The heat sink 3 and heat fin 4 are preferably made of aluminum alloy or copper alloy; the support sleeve 6, support bolt 7, support rod 8 and support plate 9 are preferably made of stainless steel.

[0034] Please refer to this carefully. Figure 4 As shown, multiple angular grooves 10 are provided on both the left and right sides of the heat sink 4 from top to bottom, and the angular grooves 10 extend to the front and rear sides of the heat sink 4.

[0035] The cross-sectional shape of the angular slot 10 is preferably triangular, which is used to increase the effective contact surface area between the heat sink and the air, thereby improving the heat dissipation capacity per unit volume.

[0036] Please refer to this carefully. Figure 1 , Figure 5 and Figure 6As shown, a soot blowing mechanism 11 is provided on the upper surface of the cover 2 behind the heat sink 3. The soot blowing mechanism 11 includes a vertical plate 12. The lower end of the vertical plate 12 is fixed to the upper surface of the cover 2. A telescopic cylinder 13 is fixed to the upper end of the rear surface of the vertical plate 12. A fixing block 14 is fixed to the telescopic end of the telescopic cylinder 13. A fixing plate 15 is fixed to the lower end of the fixing block 14. Fixing sleeves 16 are fixed to both the left and right ends of the upper surface of the fixing plate 15. A main pipe 17 is fixedly connected inside the two fixing sleeves 16. The lower surface of the main pipe 17 is located at... Multiple branch pipes 18 are evenly fixed from left to right between two fixed sleeves 16, and the branch pipes 18 can move through the fixed plate 15 in the vertical direction. Multiple blowing holes 19 are opened on the surface of the branch pipes 18. The ash blowing mechanism 11 also includes an air supply component 20, which includes a fan 21. The fan 21 is fixed to the upper surface of the box cover 2. The air outlet end of the fan 21 is fixed to an air duct 22. The end of the air duct 22 away from the fan 21 is fixed to the upper surface of the main pipe 17, and the air duct 22 is connected to the interior of the main pipe 17.

[0037] The vertical plate 12 is bolted to the upper surface of the box cover 2;

[0038] The number of branch pipes 18 is one more than the number of heat sinks 4. Each branch pipe 18 is a hollow, slender tube with its upper end connected to the interior of the main pipe 17 and its lower end closed. The position of each branch pipe 18 in the left-right direction precisely corresponds to the center line of the gap between two adjacent heat sinks 4, and the leftmost branch pipe 18 is located at the center of the left gap of the leftmost heat sink 4, and the rightmost branch pipe 18 is located at the center of the right gap of the rightmost heat sink 4. The diameter of the branch pipe 18 is smaller than the distance between two adjacent heat sinks 4.

[0039] The lower end of the branch pipe 18 is higher than the upper surface of the heat sink 3;

[0040] The telescopic cylinder 13 is preferably a pneumatic cylinder, which, after extending, drives multiple branch pipes 18 to pass between two adjacent heat sinks 4;

[0041] The effective stroke of the telescopic cylinder 13 is at least equal to the front-to-back length of the heat sink 4;

[0042] The fan 21 is used to draw air from the outside, send the airflow into the main pipe 17 and finally spray it out through the blowhole 19, blow away the dust and impurities accumulated on the surface of the heat sink 4, and prevent them from forming a heat insulation layer and affecting the heat dissipation effect.

[0043] The fan 21 is preferably a centrifugal fan or a high-pressure vortex fan, which can provide sufficient flow and pressure airflow;

[0044] The duct 22 is designed to have sufficient length margin and flexibility to compensate for the displacement generated when the telescopic cylinder 13 drives the main pipe 17 to move back and forth.

[0045] The duct 22 is preferably a corrugated pipe.

[0046] like Figure 6 As shown, a filter plate 23 is fixedly connected to the outside of the air inlet end of the fan 21;

[0047] The filter plate 23 consists of a frame and a filter screen, preferably a stainless steel wire mesh.

[0048] The telescopic cylinder 13 and the fan 21 can be controlled by manual periodic start or automatic system control mode: the operator can manually trigger them through the control panel button, or the preset program can automatically activate them according to the timer cycle or the signal of heat dissipation efficiency decline, such as when the oil temperature exceeds the threshold; after starting, the fan runs continuously, and the telescopic cylinder reciprocates within the set time to ensure that the blowing airflow completely covers the surface of the heat sink and the inside of the angular groove.

[0049] The working principle of this utility model is as follows: The heat generated by the hydraulic oil in the storage tank 1 is transferred to the support plate 9 immersed in the oil through thermal convection. The heat is conducted through the support plate 9 to the support sleeve 6, and then through the contact surface between the support sleeve 6 and the support rod 8 to the support rod 8. The support rod 8 conducts the heat upward to the heat dissipation plate 3. After absorbing the heat, the heat dissipation plate 3 increases the heat exchange area with the air through the heat dissipation fins 4 on its surface and the angular grooves 10 opened on both sides of the heat dissipation fins 4. The heat is then dissipated through natural convection or forced airflow. When dust accumulates on the surface of the heat dissipation fins 4, the fan 21 is started. External air is filtered by filter plate 23 and then drawn into fan 21 for pressurization. The airflow passes through duct 22 and main pipe 17 in sequence into each branch pipe 18, and finally sprays out from the blowhole 19 on the surface of branch pipe 18. At the same time, telescopic cylinder 13 is activated to push fixed block 14, fixed plate 15 and main pipe 17 and branch pipe 18 fixed on it to move horizontally forward, so that multiple branch pipes 18 accurately pass through the gap between adjacent heat sinks 4. The sprayed airflow sweeps across the surface of heat sink 4 and the inside of corner groove 10, blowing away dust. After the telescopic cylinder 13 completes its extension stroke, it can retract to perform reciprocating cleaning. After cleaning is completed, it resets and stops.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
