Description

Technical Field

[0001] The utility model relates to a cutting fluid filtering system and belongs to the technical field of machine tool equipment. Background Art

[0002] In the cutting process of machine tools, in order to reduce cutting heat and tool wear and improve the surface quality of workpieces, cutting fluid is needed for cooling and lubrication. However, when the cutting fluid mixes with the chips, liquid chips will be formed. If these chips are not cleaned in time, they will seriously affect the operating efficiency of the machine tool and the quality of the workpiece.

[0003] The magnetic roller paper tape filter is a common device used to remove these liquid-carrying debris. However, for larger iron chips, the magnetic roller paper tape filter can effectively adsorb and separate them. There are also a large number of non-iron chips and tiny iron particles. These particles may not be completely adsorbed by the magnetic roller paper tape filter due to their small size or weak magnetism, and will settle at the bottom of the water tank. Therefore, workers need to regularly clean the debris settled at the bottom of the water tank to ensure the normal operation of the machine tool and the quality of the workpiece. Utility Model Content

[0004] The purpose of the utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0005] The technical solution provided by the utility model is as follows: a cutting fluid filtration system, comprising a water tank, a magnetic separator and a gravity paper bag filter, the water tank having an inclined bottom, the magnetic separator and the gravity paper bag filter being arranged above the water tank, the magnetic separator being provided with a dirty liquid inlet and a filtered liquid outlet, the filtered liquid outlet being connected to the gravity paper bag filter, the magnetic separator being used for preliminary filtering of the dirty liquid, the gravity paper bag filter being used for coarse filtering of the cutting fluid flowing out of the magnetic separator, and the liquid outlet of the gravity paper bag filter being connected to the water tank.

[0006] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: the bottom of the water tank in the cutting fluid filtration system of the utility model is arranged at an angle, and gravity is used to make the impurities in the cutting fluid gradually gather to the lower side of the water tank due to gravity during the flow process, which is convenient for collection, making the subsequent filtration process simpler and more efficient.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the inclination angle α of the bottom of the water tank is 3° to 30°.

[0009] The beneficial effect of adopting the above further solution is that when the inclination angle of the bottom of the water tank is in the range of 3° to 30°, impurities in the cutting fluid can be more effectively precipitated to the lower side under the action of gravity.

[0010] Further, a horizontal bottom is arranged near the lower side of the inclined bottom.

[0011] The beneficial effect of adopting the above further solution is that the horizontal bottom is used to ensure that the cutting fluid at this position maintains a constant level height, preventing the formation of dead corners on the low side of the water tank, thereby preventing debris from accumulating in the corners.

[0012] Furthermore, it includes a lifting pump and a centrifuge, the water inlet of the lifting pump is connected to the drain pipe, the lower end of the drain pipe is inserted into the bottom of the lower side of the water tank, the lifting pump and the centrifuge are connected through a delivery pipe, the clean liquid outlet of the centrifuge is connected to the water tank through a clean liquid pipeline, and the dirty liquid outlet of the centrifuge is connected to the gravity paper bag filter through a dirty liquid pipeline.

[0013] The beneficial effect of adopting the above further scheme is that the cutting fluid at the bottom of the water tank is filtered again by a centrifuge, which not only ensures the cleanliness of the cutting fluid and improves the quality and precision of workpiece processing, but also workers no longer need to regularly clean the sediment at the bottom of the water tank, thereby greatly reducing the workload and improving work efficiency.

[0014] Furthermore, it also includes an industrial pump, which is connected to the water tank and is used to lift the filtered cutting fluid in the water tank to the machine tool for recycling.

[0015] The beneficial effect of adopting the above further solution is that the design of connecting the industrial pump with the water tank can effectively lift the filtered cutting fluid in the water tank to the machine tool for recycling. This not only reduces the waste of cutting fluid and reduces production costs, but also improves the continuity and stability of machine tool processing.

[0016] Furthermore, the industrial pump is installed above the water tank.

[0017] The beneficial effect of adopting the above further solution is that installing the industrial pump above the water tank can shorten the liquid delivery path and reduce energy loss during the pumping process. At the same time, this layout is also conducive to reducing the complexity and maintenance difficulty of the pipeline and improving the overall reliability of the system.

[0018] Furthermore, the dirty liquid pipeline and the clean liquid pipeline both adopt steel wire hoses.

[0019] The beneficial effect of adopting the above further scheme is that the steel wire hose has good flexibility and corrosion resistance and can adapt to various complex working environments. In addition, the steel wire hose is easy to install and replace, which reduces the maintenance cost of the system.

[0020] Further, the centrifuge is arranged close to the lower side of the water tank.

[0021] The beneficial effect of adopting the above further solution is that the centrifuge is arranged close to the lower side of the water tank, which can shorten the liquid transportation path, help reduce the risk of impurity deposition and pipeline blockage during liquid transportation, and improve the filtration efficiency of the centrifuge.

[0022] Furthermore, the gravity paper bag filter is arranged close to the high side of the water tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1 and Figure 2 As shown, a cutting fluid filtration system includes a water tank 1, a magnetic separator 2 and a gravity paper bag filter 3, the water tank 1 has an inclined bottom 101 inclined to one side, the magnetic separator 2 and the gravity paper bag filter 3 are arranged above the water tank 1, the magnetic separator 2 is provided with a dirty liquid inlet and a filtered liquid outlet, the filtered liquid outlet is connected with the gravity paper bag filter 3, the dirty liquid enters the magnetic separator 2 through the dirty liquid inlet for preliminary filtration, the filtered cutting fluid flows into the gravity paper bag filter 3 through the filtered liquid outlet for coarse filtration, the liquid outlet of the gravity paper bag filter 3 is connected with the water tank 1, and the cutting fluid after coarse filtration by the gravity paper bag filter 3 enters the water tank 1.

[0029] The implementation of the utility model does not limit the inclination angle of the bottom of the water tank 1. The inclination angle α of the bottom of the water tank 1 can be set to 3°~30°. As long as this inclination angle can make the impurities in the cutting fluid effectively settle to the lower side under the action of gravity, it should be within the protection scope of the utility model.

[0030] A horizontal bottom 102 is provided near the lower side of the inclined bottom 101 of the water tank 1. The high side of the water tank 1 refers to the side that is at a higher position due to the inclination of the bottom; the low side of the water tank 1 refers to the side that is at a lower position due to the inclination of the bottom. A horizontal plane is provided at the lower side of the water tank 1, that is, the area near the lower side is designed to be horizontal. The horizontal bottom 102 is used to ensure that the cutting fluid at this position maintains a constant level height, prevents the formation of a dead corner at the lower side of the water tank 1, and thus prevents debris from accumulating in the corner.

[0031] The cutting fluid filtration system also includes a lifting pump 4 and a centrifuge 5. The water inlet of the lifting pump 4 is connected to a drain pipe, and the lower end of the drain pipe is inserted into the bottom of the lower side of the water tank 1. The lifting pump 4 is connected to the centrifuge 5 through a delivery pipe 6. The clean liquid outlet of the centrifuge 5 is connected to the water tank 1 through a clean liquid pipeline 7, and the dirty liquid outlet of the centrifuge 5 is connected to the gravity paper bag filter 3 through a dirty liquid pipeline 8. The centrifuge 5 generates centrifugal force by high-speed rotation to separate impurities in the cutting fluid. The clean liquid outlet of the centrifuge 5 is reconnected to the water tank 1 through the clean liquid pipeline 7, and the relatively clean cutting fluid treated by the centrifuge 5 is returned to the water tank 1 for recycling. The mixture of tiny particles and liquid that are not completely separated in the centrifuge 5 enters the gravity paper bag filter 3, and the impurities are further removed by the filtering effect of the paper bag.

[0032] The cutting fluid filtering system further comprises an industrial pump 9 , which is connected to the water tank 1 and is used to lift the filtered cutting fluid in the water tank 1 to the machine tool for recycling.

[0033] The industrial pump 9 is installed above the water tank 1 .

[0034] In this embodiment, the dirty liquid pipeline 8 and the clean liquid pipeline 7 are both made of steel wire hoses.

[0035] The centrifuge 5 is arranged near the lower side of the water tank 1. The gravity paper bag filter 3 is arranged near the higher side of the water tank 1. The liquid delivery path can be shortened and the energy loss in the pumping process can be reduced.

[0036] The process of filtering cutting fluid of the cutting fluid filtering system of the utility model is as follows:

[0037] The dirty liquid first enters the magnetic separator 2 through the dirty liquid inlet for preliminary filtration, and the filtered cutting fluid flows into the gravity paper bag filter 3 through the filtrate outlet for coarse filtration. The cutting fluid coarsely filtered by the gravity paper bag filter 3 enters the water tank 1, and the impurities in the cutting fluid gradually gather to the lower side of the water tank 1 due to gravity during the flow process. The lifting pump 4 lifts the cutting fluid with impurities on the lower side of the water tank 1 to the centrifuge 5, and the centrifuge 5 generates centrifugal force by high-speed rotation to separate the impurities in the cutting fluid. The clean liquid outlet of the centrifuge 5 is reconnected to the water tank 1 through the clean liquid pipeline 7, and the relatively clean cutting fluid treated by the centrifuge 5 is returned to the water tank 1 for recycling. The tiny particles and liquid mixture that are not completely separated in the centrifuge 5 enter the gravity paper bag filter 3 through the dirty liquid pipeline 8, and the impurities are further removed by the filtering effect of the paper bag.

[0038] The bottom of the water tank 1 in the cutting fluid filtering system of the utility model is tilted, and gravity is used to make the impurities in the cutting fluid gradually gather to the lower side of the water tank 1 due to gravity during the flow process. The cutting fluid at the bottom of the water tank 1 is filtered again by the centrifuge 5, which not only ensures the cleanliness of the cutting fluid and improves the quality and accuracy of workpiece processing, but also workers no longer need to regularly clean the sediment at the bottom of the water tank 1, thereby greatly reducing the workload and improving work efficiency.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
