Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a recovery device with liquid separation and self-cleaning functions. Background Art

[0002] On a CNC machining production line, both the workpieces to be machined and the workpieces after machining need to be industrially cleaned. In order to achieve rapid cleaning of the workpieces, people have designed a workpiece cleaning center, that is, a cleaning machine. The workpiece is placed in the cleaning machine and is rinsed in all directions using cutting fluid and cleaning fluid, thereby achieving rapid industrial flow-line cleaning.

[0003] For example, the authorization announcement number CN205966643U discloses a cleaning liquid recovery structure of a workpiece cleaning equipment, which includes a cleaning center, the cleaning center has a closed cleaning bin, the bottom of the cleaning bin is provided with a cone-shaped cleaning liquid discharge outlet, a movable recovery box for recovering the cleaning liquid is provided directly below the cleaning liquid discharge outlet, a transition trough pipe is provided above the recovery box corresponding to the cleaning liquid discharge outlet, a cleaning liquid collecting port corresponding to the cleaning liquid discharge outlet is provided on the upper side of one end of the transition trough pipe, the lower side of the transition trough pipe is connected to the recovery box, the other end of the transition trough pipe is a slag discharge end, and a filter residue conveying assembly with a length and width matching the transition trough pipe is provided below the transition trough pipe, the filter residue conveying assembly includes a filter conveyor belt, the filter conveyor belt is covered with filter holes, the cleaning liquid collection port corresponds to the upper belt surface of the filter conveyor belt, and the upper belt surface can filter the debris in the cleaning liquid and convey it to the slag discharge end. However, while this recovery structure can recycle the cleaning fluid, the actual cleaning process requires the use of cutting fluid and cleaning fluid to clean the workpiece separately. This requires two sets of recovery structures to achieve the recovery of cutting fluid and cleaning fluid respectively. The two sets of recovery structures make the overall layout larger and not conducive to a reasonable layout. In addition, after the cleaning is completed, there will be oil stains in the cutting fluid and cleaning fluid. If these are not cleaned in time, the yield rate of subsequent cleaning will be affected, which has significant limitations. Summary of the Invention

[0033] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] like Figures 1 to 7 As shown, the present invention discloses a recovery device with liquid separation and self-cleaning functions, including a substrate 1, on which a drain box 2 is fixed. In this preferred embodiment, the top of the drain box 2 is provided with an inlet 21 connected to the liquid outlet of the cleaning machine 100, and the bottom of the drain box 2 is provided with a drain pipe I22 and a drain pipe II23 for discharging the liquid flowing into the inlet 21.

[0037] In the present invention, the drainage box 2 is provided with a liquid separation component 3 for selectively discharging liquid from the drainage pipe I22 or the drainage pipe II23. Specifically, the liquid separation component 3 is at least pivotally mounted on a rotating shaft 35 on the drainage box 2, and a liquid separation box 31 is fixed on the rotating shaft 35. An opening I32 is provided on one side of the liquid separation box 31, and an opening II is provided on the other side. A raised block 33 is provided on the top of the liquid separation box 31, and a cover plate 39 is provided on both sides of the raised block 33. The setting of the cover plate 39 can prevent external impurities from falling into the drainage box, thereby ensuring its cleanliness. The raised block 33 is placed in the inlet 21, and a first liquid inlet 34 is provided on it. A drive motor 36 is fixed on the drainage box 2, and the motor shaft of the drive motor 36 is connected to the rotating shaft 35 through a reducer 37. The aforementioned drive motor controls the selective deflection of the liquid separation box 31, allowing the cleaning fluid or cutting fluid flowing in from the first liquid inlet 34 to be selectively discharged from opening I or opening II. This operation is stable and reliable, and the drive motor has high precision and fast response characteristics, greatly improving work efficiency. In addition, the configuration of the liquid separation assembly 3 realizes automatic separation of cleaning fluid and cutting fluid, achieving high integration, reducing occupied space, and facilitating reasonable layout.

[0038] However, the above-mentioned liquid separation component 3 will have this problem during the liquid separation process, namely: after the driving motor controls the deflection of the liquid separation box 31, the driving motor will stop working. At this time, the liquid separation box 31 remains in a deflected state, but under the impact of the cleaning fluid or cutting fluid, the liquid separation box 31 may be deflected, and accurate liquid separation of the cleaning fluid or cutting fluid cannot be achieved.

[0039] In order to solve the above problem, support plates 9 are fixedly provided on the inner walls of both sides of the liquid separation box 31. The support plates 9 are fixedly provided with guide rails 91. The guide rails 91 are provided with guide blocks 92 adapted thereto. The guide blocks 92 are fixedly provided with weighing devices 93. The weighing devices 93 are fixedly provided with a supporting frame 94. A filter screen 95 is placed in the supporting frame 94. Buffers 96 are also fixedly provided at both ends of the support plates 9. The distance between the buffers 96 is greater than the length of the supporting frame 94, and the maximum distance between the buffers 96 and the opening 132 is less than or equal to the length of the supporting frame 94. In the above, the supporting frame 94 can slide on the guide rails 91 under the action of gravity, so that during the liquid separation process, the supporting frame keeps the liquid separation box 31 in an inclined state at all times, which can prevent the liquid separation box 31 from deflecting under the impact of the cleaning fluid or cutting fluid, thereby ensuring the accuracy of the liquid separation.

[0040] In the present invention, the filter 95 can filter the cleaning liquid and the cutting liquid for the first time to improve the cleanliness of the cleaning liquid or cutting fluid when it falls into the corresponding scraping bin, which is beneficial for subsequent processing. At the same time, the weighing device 93 can weigh the supporting frame 94 in real time. When it exceeds the threshold value predetermined by the weighing device 93, it reminds you to replace the filter, which can avoid excessive impurities on the filter 95 and affect the use effect. In addition, since the maximum distance between the buffer 96 and the opening I32 is less than or equal to the length of the filter 95, the filter 95 can be easily removed. The operation is simple and convenient, and it is easy to quickly replace it, which greatly improves work efficiency. The setting of the buffer 96 can avoid hard collisions between the supporting frame 94 and the liquid separation box 31, thereby extending the service life.

[0041] A scraping bin I11 is provided directly below the liquid outlet of the discharge pipe I22, and a liquid storage bin I13 is fixedly provided on the outside of the scraping bin I11. A pressure pump I17 is fixedly provided on the liquid storage bin I13, and the pressure pump I17 is connected to the upper liquid port of the cleaning machine 100 through a connecting pipe I.

[0042] A scraping bin II12 is located directly below the liquid outlet of the discharge pipe II23. A liquid storage bin II14 and an oil removal bin 15 are fixedly connected to each other on the outside of the scraping bin II12. A heater 16 is fixedly installed on the liquid storage bin II14. The heater 16 is fixedly installed with heating wires. The heating wires can heat the cleaning liquid in the liquid storage bin II14, thereby improving the cleaning effect of the cleaning machine 100. A pressure pump II18 and a flow pump 19 are fixedly installed on the liquid storage bin II14. The pressure pump I17, pressure pump II18, and flow pump 19 are all connected to the cleaning machine 100 through corresponding pipelines.

[0043] In the present invention, a scraping assembly 4 is fixedly provided in the scraping bin I11 and the scraping bin II12, and the scraping assembly 4 at least includes a scraping box 41 fixedly provided in the scraping bin I11 and the scraping bin II12, and the scraping box 41 includes a fixed horizontal end 42 and an inclined end 43, a driven roller is pivoted in the horizontal end 42, and an active roller is pivoted in the inclined end 43, and a transition roller is pivoted at the junction of the horizontal end 42 and the inclined end 43, and a scraping belt is wound around the driven roller, the transition roller and the active roller, and a servo motor 44 is fixedly provided on the inclined end 43, and the motor shaft of the servo motor 44 is connected to the active roller through a reducer 45; a second liquid inlet 40 is opened on the horizontal end 42, and a liquid inlet frame 46 is fixed on the second liquid inlet 40, and the liquid inlet frame 46 is located directly below the liquid outlet of the drain pipe I22 and the liquid outlet of the drain pipe II23. In the above, the driven roller, transition roller and active roller cooperate with each other to control the transmission of the scraper belt, which can discharge impurities in the scraper bin, achieve secondary filtration, and maximize the cleanliness of the cleaning fluid and cutting fluid.

[0044] Another key design feature of the present invention is that both the de-oiling tank 15 and the liquid storage tank 113 are equipped with a de-oiling assembly 5 and a circulation pump 6. The circulation pump 6 is connected to the corresponding scraping tank 111 or scraping tank 112 via a filter pump 7. Specifically, the de-oiling assembly 5 includes at least a bracket 51 fixed to the de-oiling tank 15 and the liquid storage tank 113. A drive roller is pivotally mounted on the bracket 51. A transmission roller 52 is pivotally mounted within the de-oiling tank 15 and the liquid storage tank 113. A transmission belt 53 is wound between the drive roller and the transmission roller 52. An oil-absorbing film is applied to the surface of the transmission belt 53. A transmission motor 54 is fixed to the bracket 51, the motor shaft of which is fixedly connected to the drive roller. An oil collection box 55 and an oil scraper 56 are also fixed to the bracket 51. One end of the oil scraper 56 abuts the oil-absorbing film, and the other end is located directly above the oil collection box 55. In the above, the oil absorption membrane absorbs the oil in the cleaning fluid and the cutting fluid, and after adsorption, the oil is scraped out into the oil collection box through the oil scraper, thereby separating the oil in the cleaning fluid and the cutting fluid, and being able to place the oil separately, thereby ensuring the cleanliness of the cleaning fluid and improving the subsequent yield rate.

[0045] In the present invention, each of the liquid storage tank I13, liquid storage tank II14, and de-oiling tank 15 is equipped with a liquid level gauge 8. The liquid level gauge 8 comprises at least a liquid level box 81 fixed to each of the liquid storage tanks I13, II14, and de-oiling tank 15. The liquid level box 81 is provided with a chute 82, within which a corresponding slider 83 is positioned.
