Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic station oil replenishment, in particular to a temporary oil replenishment device for a furnace front hydraulic station. Background Art

[0002] The temporary oil replenishing device of the hydraulic station in front of the furnace is a device used to replenish and maintain the oil level of the hydraulic system. It is mainly used in industrial processes such as steelmaking and casting. It monitors and replenishes the hydraulic oil in real time through components such as oil tanks, pumps, valves and liquid level monitoring systems to ensure that the hydraulic system maintains appropriate oil level and pressure during operation, thereby avoiding equipment failure due to lack of oil and ensuring the continuity and safety of production.

[0003] In the prior art, the oil level is detected by a sensor or a liquid level gauge. When the oil level is lower than the set safety range, the oil replenishment pump will be started. At this time, the hydraulic oil in the tank will be transported to the hydraulic system through a pipeline to ensure that the oil can quickly reach the part that needs to be replenished. At the same time, during the oil replenishment process, it is necessary to pay close attention to the working status of the oil replenishment pump and the oil level changes of the hydraulic station. When the oil replenishment is completed, the oil replenishment pump will be turned off, and the oil replenishment operation will be completed.

[0004] There are still some problems in the actual application of the above scheme. Due to the aging and corrosion of storage containers due to long-term use, impurities generated inside the container are mixed into the hydraulic oil, which in turn causes the hydraulic oil flowing into the oil tank to contain impurities. During the storage process, the impurities will react with the additives in the hydraulic oil, thereby accelerating the oxidation and deterioration of the oil, resulting in a decrease in the performance of the oil. The decrease in oil performance will directly affect the operating efficiency and stability of the hydraulic system. At the same time, when the impurity particles circulate in the hydraulic system, they will contact the friction surfaces of hydraulic components (such as pumps, valves, cylinders, etc.), resulting in increased wear on the component surfaces. In addition, the added reciprocating cleaning mechanism will clean the impurities with the hydraulic oil out of the upper surface of the filter plate, which will lead to the loss of hydraulic oil, thereby increasing production costs.

[0005] To this end, the present invention provides a temporary oil replenishing device for a hydraulic station in front of a furnace. Summary of the invention

Since the bottom of the reciprocating scraper is in contact with the upper surface of the bottom of the inner cavity of the filter frame, and since the hydraulic oil has fluidity, impurities attached to the side wall of the filter frame will follow the hydraulic oil to flow to the upper surface of the bottom of the inner cavity of the filter frame, so that the hydraulic oil and impurity mixture gathered on the upper surface of the bottom of the inner cavity of the filter frame can be cleaned out of the upper surface of the bottom of the inner cavity of the filter frame by the reciprocating movement of the reciprocating scraper, thereby improving the filtration efficiency and ensuring the cleanliness of the hydraulic oil.

Since the limiting arc piece is slidably connected in the annular guide groove, the limiting arc piece will be driven to move synchronously when the rotating shaft rotates. When the limiting arc piece moves with the rotating shaft, it will drive the fixed column rotatably connected with it to move synchronously. At the same time, it will also drive the reciprocating cylinder fixed with the fixed column to move synchronously. Since the second guide block slides in the third guide groove, and the second guide block and the reciprocating cylinder are fixed, the reciprocating cylinder will move along the guide of the third guide groove, and at the same time, it will drive the reciprocating plate fixed with the reciprocating cylinder to move synchronously. Through the movement of the reciprocating plate, the impurities and hydraulic oil mixture scraped off by the reciprocating scraper to the collecting frame can be squeezed with the side wall of the collecting frame, so that the hydraulic oil can be recovered, thereby reducing the demand for new hydraulic oil and reducing production costs.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1

[0037] like Figures 1 to 9 As shown, a temporary oil replenishing device for a furnace hydraulic station according to an embodiment of the present invention comprises a support frame 1, an oil replenishing device 2 is arranged on the upper part of the support frame 1, the oil replenishing device 2 comprises an oil tank 201, an oil outlet valve 202 is fixedly connected to the side of the lower part of the oil tank 201, an oil level gauge 203 is fixedly connected to the middle part of the oil tank 201 near the oil outlet valve 202, an oil inlet valve 204 is fixedly connected to the top of the oil tank 201, and a reciprocating cleaning mechanism 3 is arranged on the inner cavity side wall of the oil replenishing device 2;

[0038] The reciprocating cleaning mechanism 3 includes a filter frame 301 fixedly arranged on the inner side wall of the oil tank 201, a moving block 306 is slidably arranged on the side of the filter frame 301, and a reciprocating scraper 307 for cleaning is fixedly arranged at the bottom of the moving block 306. The reciprocating motion of the reciprocating scraper 307 can clean the upper part of the filter frame 301.

[0039] Specifically, due to the aging and corrosion of the storage container after long-term use, impurities generated inside the container are mixed into the hydraulic oil, which in turn causes the hydraulic oil flowing into the oil tank 201 to contain impurities. During the storage process, the impurities react with the additives in the hydraulic oil, thereby accelerating the oxidation and deterioration of the oil, resulting in a decrease in the performance of the oil. The decrease in the performance of the oil will directly affect the operating efficiency and stability of the hydraulic system.

[0040] Therefore, the present invention solves this problem by setting a corresponding structure. The temporary oil replenishing device of the hydraulic station in front of the furnace described in the present invention, when it is necessary to replenish oil, opens the oil outlet valve 202 to replenish the hydraulic oil stored in the oil tank 201 to the hydraulic system through the oil outlet valve 202. At this time, the amount of hydraulic oil stored in the oil tank 201 is determined by observing the oil level gauge 203, and the hydraulic oil outside the oil tank 201 is replenished into the oil tank 201 by starting the oil inlet valve 204. When the hydraulic oil in the oil level gauge 203 moves to two-thirds of the height, the oil inlet valve 204 is immediately closed to stop replenishing the hydraulic oil to the oil tank 201. However, since the hydraulic oil replenished into the oil tank 201 through the oil inlet valve 204 will contain impurities, these impurities will cause During the storage process, impurities will react with additives in the hydraulic oil, thereby accelerating the oxidation and deterioration of the oil and causing the performance of the oil to decline. The decline in oil performance will directly affect the operating efficiency and stability of the hydraulic system. At this time, the hydraulic oil entering the oil tank 201 through the oil inlet valve 204 is filtered by the filter frame 301, and the sliding of the moving block 306 drives the reciprocating scraper 307 to move synchronously, so that the mixture of dirt and hydraulic oil temporarily accumulated on the upper surface of the bottom of the inner cavity of the filter frame 301 can be cleaned out of the filter frame 301, thereby improving the filtering efficiency and ensuring the cleanliness of the hydraulic oil. At the same time, it can also extend the service life of the hydraulic components and improve the stability and reliability of the system.

[0041] Embodiment 2

[0044] Specifically, when the oil replenishing work is completed and the oil replenishing work of the oil tank 201 is completed by starting the oil inlet valve 204, the first motor 304 is started. When the first motor 304 is started, it will drive the rotating screw 305 fixedly connected to its output shaft to rotate. Since the rotating screw 305 and the moving block 306 are threadedly connected, the moving block 306 will move synchronously when the rotating screw 305 rotates, thereby providing corresponding power support for the work of subsequent components.

[0045] like Figure 4 and Figure 5As shown, the filter frame 301 described in this embodiment is fixedly connected to one side of the oil tank 201 close to the oil inlet valve 204, and a first guide groove 302 is opened on the side of the filter frame 301. A first guide block 303 is slidably connected inside the first guide groove 302, and a moving block 306 is fixedly connected to the side of the first guide block 303 away from the first guide groove 302.

[0046] Specifically, when the moving block 306 moves synchronously with the rotating screw 305, since the first guide block 303 fixedly connected to the moving block 306 slides inside the first guide groove 302, when the first guide groove 302 rotates, the first guide block 303 will be affected by the limiting effect of the first guide groove 302 and move in a straight line, and at the same time, the moving block 306 is prompted to move in a straight line along the guide of the first guide groove 302.

[0047] like Figure 4 As shown, in this embodiment, a reciprocating scraper 307 is fixedly connected to the bottom of the moving block 306 , and a first blocking plate 308 is fixedly connected to the middle of the side of the reciprocating scraper 307 .

[0048] Specifically, when the moving block 306 moves linearly along the guide of the first guide groove 302, it will drive the reciprocating scraper 307 fixedly connected to its bottom to move synchronously, and at the same time, it will drive the first baffle plate 308 fixed in the middle to move synchronously. Since the bottom of the reciprocating scraper 307 is in contact with the upper surface of the bottom of the inner cavity of the filter frame 301, and since the hydraulic oil has fluidity, the impurities attached to the side wall of the filter frame 301 will follow the hydraulic oil to flow to the upper surface of the bottom of the inner cavity of the filter frame 301, so that the hydraulic oil and impurity mixture gathered on the upper surface of the bottom of the inner cavity of the filter frame 301 can be cleaned out of the upper surface of the bottom of the inner cavity of the filter frame 301 through the reciprocating movement of the reciprocating scraper 307, thereby improving the filtration efficiency and ensuring the cleanliness of the hydraulic oil. At the same time, it can also extend the service life of the hydraulic components and improve the stability and reliability of the system.

[0049] like Figure 4 and Figure 5 As shown, in this embodiment, the second baffle plate 310 is fixedly connected to a reciprocating spring 311 on one side away from the first baffle plate 308, and one end of the reciprocating spring 311 away from the second baffle plate 310 is fixedly connected to the inner cavity side wall of the oil tank 201. The second baffle plate 310 is composed of a vertical plate and a horizontal plate, and the vertical plate of the second baffle plate 310 is adapted to the height of the first baffle plate 308.

[0050] Specifically, when the first baffle plate 308 approaches the second baffle plate 310 driven by the reciprocating scraper 307, the side of the first baffle plate 308 away from the reciprocating scraper 307 will first contact the vertical plate of the second baffle plate 310 and push the second baffle plate 310 to move. At this time, the reciprocating spring 311 will change from an unstressed state to a compressed state. Through the movement of the second baffle plate 310, the mixture of hydraulic oil and impurities gathered on the upper surface of the bottom of the inner cavity of the filter frame 301 can be pushed away from the upper surface of the bottom of the inner cavity of the filter frame 301.

[0051] like Figure 4 and Figure 5 As shown, the filter frame 301 described in this embodiment is provided with a second guide groove 309 at the lower part near the rotating screw 305. The second guide groove 309 is below the first guide groove 302 and is shorter than the first guide groove 302. A second baffle plate 310 is slidably connected inside the second guide groove 309, and a protrusion matching the size of the second guide groove 309 is provided on the side of the second baffle plate 310.

[0052] Specifically, since the second guide grooves 309 matching the size of the second guide grooves 309 are provided on both sides of the second baffle plate 310 , the second baffle plate 310 will move linearly along the guidance of the second guide grooves 309 when pushed by the first baffle plate 308 .

[0053] like Figure 8 As shown, the reciprocating oil pressure mechanism 4 in this embodiment includes a second motor 407 . The second motor 407 is fixedly disposed on the side wall of the collecting frame 401 . The output shaft of the second motor 407 is fixedly connected to a rotating shaft 408 .

[0054] Specifically, when the reciprocating scraper 307 pushes the mixture of hydraulic oil and impurities into the collecting frame 401, the second motor 407 is started, so that the second motor 407 drives the rotating shaft 408 fixedly connected to its output shaft to rotate synchronously, thereby providing power support for the subsequent operation.

[0055] like Figure 6 and Figure 8 As shown, the outer ring surface of the rotating shaft 408 in this embodiment is provided with an annular guide groove 409, the limiting arc plate 406 is slidably connected in the annular guide groove 409, and the end of the reciprocating cylinder 404 away from the second motor 407 is fixedly connected with a reciprocating plate 410, and the two sides and the bottom of the reciprocating plate 410 are in contact with the inner cavity of the collection frame 401.

[0056] like Figure 8 and Fig. 9As shown, in this embodiment, the second guide block 403 is fixedly connected to a reciprocating cylinder 404 on one side away from the third guide groove 402, a cavity is opened inside the reciprocating cylinder 404, a fixed column 405 is fixedly connected to the inner annular surface of the reciprocating cylinder 404, and the other end of the fixed column 405 is rotatably connected to a limiting arc plate 406.

[0057] Specifically, when the rotating shaft 408 rotates, the annular guide groove 409 opened on its outer ring surface will be driven to rotate synchronously. Since the limiting arc piece 406 is slidably connected in the annular guide groove 409, the limiting arc piece 406 will be driven to move synchronously when the rotating shaft 408 rotates. When the limiting arc piece 406 moves with the rotating shaft 408, it will drive the fixed column 405 rotatably connected thereto to move synchronously, and will also drive the reciprocating moving cylinder 404 fixed to the fixed column 405 to move synchronously.

[0058] like Figure 6 As shown, a reciprocating oil pressing mechanism 4 for pressing oil is arranged on the side of the oil replenishing device 2 in this embodiment, and the reciprocating oil pressing mechanism 4 includes a collecting frame 401, and the collecting frame 401 is slidably connected to the side wall of the oil tank 201, and a third guide groove 402 is opened on the side wall inside the collecting frame 401, and a second guide block 403 is slidably connected inside the third guide groove 402.

[0059] Specifically, since the second guide block 403 slides in the third guide groove 402, and the second guide block 403 and the reciprocating cylinder 404 are fixed, the reciprocating cylinder 404 will move along the guide of the third guide groove 402, and at the same time will drive the reciprocating plate 410 fixed to the reciprocating cylinder 404 to move synchronously, and the movement of the reciprocating plate 410 can squeeze the impurities and hydraulic oil mixture scraped off by the reciprocating scraper 307 to the collecting frame 401, so that the hydraulic oil can be recycled, thereby reducing the demand for new hydraulic oil, thereby reducing production costs, and at the same time, since the height of the hydraulic oil inside the oil tank 201 is two-thirds of its own height, and the reciprocating cleaning mechanism 3 and the reciprocating oil pressing mechanism 4 are both located on the side of the oil tank 201 close to the oil inlet valve 204, the reciprocating cleaning mechanism 3 and the reciprocating oil pressing mechanism 4 both maintain a certain distance from the hydraulic oil surface.

[0060] Working principle, when the oil replenishing work is completed, and at the same time, the oil replenishing work of the oil tank 201 is completed by starting the oil inlet valve 204, the first motor 304 is started. When the first motor 304 is started, it will drive the rotating screw 305 fixedly connected to its output shaft to rotate. Since the rotating screw 305 and the moving block 306 are threadedly connected, the moving block 306 will move synchronously while the rotating screw 305 rotates, thereby providing corresponding power support for the work of subsequent components.

[0061] When the moving block 306 moves synchronously with the rotating screw 305, since the first guide block 303 fixedly connected to the moving block 306 slides inside the first guide groove 302, when the first guide groove 302 rotates, the first guide block 303 will be affected by the limiting effect of the first guide groove 302 and move in a straight line, and at the same time, the moving block 306 is prompted to move in a straight line along the guidance of the first guide groove 302.

[0062] When the moving block 306 moves linearly along the guide of the first guide groove 302, it will drive the reciprocating scraper 307 fixedly connected to its bottom to move synchronously, and at the same time, it will drive the first baffle plate 308 fixed in the middle to move synchronously. Since the bottom of the reciprocating scraper 307 is in contact with the upper surface of the bottom of the inner cavity of the filter frame 301, and since the hydraulic oil has fluidity, the impurities attached to the side wall of the filter frame 301 will follow the hydraulic oil to flow to the upper surface of the bottom of the inner cavity of the filter frame 301, so that the hydraulic oil and impurity mixture gathered on the upper surface of the bottom of the inner cavity of the filter frame 301 can be cleaned out of the upper surface of the bottom of the inner cavity of the filter frame 301 through the reciprocating movement of the reciprocating scraper 307, thereby improving the filtration efficiency and ensuring the cleanliness of the hydraulic oil. At the same time, it can also extend the service life of the hydraulic components and improve the stability and reliability of the system.

[0063] When the first baffle plate 308 approaches the second baffle plate 310 driven by the reciprocating scraper 307, the side of the first baffle plate 308 away from the reciprocating scraper 307 will first contact the vertical plate of the second baffle plate 310 and push the second baffle plate 310 to move. At this time, the reciprocating spring 311 will change from an unstressed state to a compressed state. Through the movement of the second baffle plate 310, the mixture of hydraulic oil and impurities gathered on the upper surface of the bottom of the inner cavity of the filter frame 301 can be pushed away from the upper surface of the bottom of the inner cavity of the filter frame 301.

[0064] Since the second guide grooves 309 matching the size of the second guide grooves 309 are disposed on both sides of the second blocking plate 310 , the second blocking plate 310 will move linearly along the guidance of the second guide grooves 309 when pushed by the first blocking plate 308 .

[0065] When the reciprocating scraper 307 pushes the mixture of hydraulic oil and impurities into the collecting frame 401, the second motor 407 is started, so that the second motor 407 drives the rotating shaft 408 fixedly connected to its output shaft to rotate synchronously, thereby providing power support for the subsequent operation.

[0066] When the rotating shaft 408 rotates, the annular guide groove 409 provided on its outer ring surface will be driven to rotate synchronously. Since the limiting arc piece 406 is slidably connected in the annular guide groove 409, the limiting arc piece 406 will be driven to move synchronously when the rotating shaft 408 rotates. When the limiting arc piece 406 moves with the rotating shaft 408, it will drive the fixed column 405 connected thereto for rotation to move synchronously, and will also drive the reciprocating moving cylinder 404 fixed to the fixed column 405 to move synchronously.

[0067] Since the second guide block 403 slides in the third guide groove 402, and the second guide block 403 and the reciprocating cylinder 404 are fixed, the reciprocating cylinder 404 will move along the guide of the third guide groove 402, and at the same time will drive the reciprocating plate 410 fixed to the reciprocating cylinder 404 to move synchronously. Through the movement of the reciprocating plate 410, the impurities and hydraulic oil mixture scraped off by the reciprocating scraper 307 to the collecting frame 401 can be squeezed, so that the hydraulic oil can be recycled, thereby reducing the demand for new hydraulic oil, thereby reducing production costs. At the same time, since the height of the hydraulic oil inside the oil tank 201 is two-thirds of its own height, and the reciprocating cleaning mechanism 3 and the reciprocating oil pressure mechanism 4 are both located on the side of the oil tank 201 close to the oil inlet valve 204, the reciprocating cleaning mechanism 3 and the reciprocating oil pressure mechanism 4 both maintain a certain distance from the hydraulic oil surface.

[0068] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
