Abstract
Description
Technical Field
[0001] The utility model relates to a machine tool water tank with multi-stage filtration. Background Art
[0002] For most machining tools on the market currently, in order to enable the stable operation of the machine tool, a water tank with a filtering function is generally designed and used to filter and separate fine chips and other impurities (sludge) in the cutting fluid during the machining process of the machine tool.
[0003] The technical solutions of the machine tool filtering water tanks designed by machine tool manufacturers on the market are shown in the following figure (1): 1. Chip conveyor belt; 2. Chip car; 3. Water tank space A; 4. Chip outlet of the chip conveyor; 5. Filtering device; 6. Water tank space B.
[0004] The above-mentioned machine tool filtering water tank device is usually used to solve the technical problems that the chip conveyor does not filter iron chips sufficiently, and fine chips are not easily collected, resulting in chip blockage of the filtering device.
[0005] Main working principle: The cutting fluid mixed with a large amount of waste chips generated after machining by the machine tool is discharged onto the chip conveyor belt. The chip conveyor belt drives most of the solid waste chips to the chip outlet of the chip conveyor and makes the waste chips fall into the chip car. The function of the chip car is mainly to collect waste chips. The chip conveyor and the chip conveyor belt are installed in the water tank space A. Filter holes are opened below the chip conveyor belt. The cutting fluid and fine chips will enter the water tank space A through the filter holes. As shown in Figure (1), the cutting fluid and fine chips will enter the water tank space B along the arrow direction. A set of filtering device is installed between them. The filtering device mainly includes a filter plate, an asbestos mesh and other structures for further filtering and separating finer chips in the cutting fluid. The clean cutting fluid entering the water tank space B through double-layer filtration can be taken out by the water pump and continued to be provided for the machine tool to use.
[0006] Disadvantages of this structure:
[0007] 1. Some high-precision and high-end machine tools have very high requirements for the cutting fluid during use, requiring that there should be no impurities in the cutting fluid. Using cutting fluid containing fine chips and impurities (sludge) will cause problems such as scratches on the surface of the machined product, tool wear, and affect the service life of high-precision machine tools. It will also be very difficult to clean and maintain the machine tool later. Only using the design scheme of the above-mentioned machine tool filtering water tank far cannot meet the use requirements.
[0008] 2. The main principle of the machine tool filtration water tank relies on the self-flow of the cutting fluid in the water tank to achieve the filtration function; problems will occur during actual use. Fine chips and impurities (silt) will accumulate inside the water tank due to their own gravity and cannot be filtered out. Therefore, after the water tank has been used for a period of time, it is necessary to disassemble the water tank for manual cleaning. Summary of the Utility Model

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-5 , the embodiments of the present utility model include:
[0025] A multi-stage filtering machine tool water tank, including a water tank, a chip conveyor belt 1, a roller filter 2, a vortex separator 3, an iron chip cart 4, and a bag filter 5.
[0026] Among them, the water tank includes a first water tank 6 and a second water tank 7. The first water tank 6 is arranged in a T-shaped structure. The longitudinal end box body 61 of the first water tank 6 is inserted into the transverse end box body 62, and the end of the longitudinal end box body 61 is spaced from the inner wall of the transverse end box body 62 to form a flow-through channel, facilitating the flow of the cutting fluid.
[0027] An outlet 63 is provided on one side of the longitudinal end box body 61 of the first water tank 6 in the transverse end box body 62. The chip conveyor belt 1 is arranged in the longitudinal end box body 61 of the first water tank 6, and the cutting fluid of the chip conveyor belt 1 flows out from the outlet 63.
[0028] The roller filter 2 is arranged on one side of the transverse end box body 62 of the chip conveyor belt 1 for the first filtration of fine chips in the cutting fluid. The remaining cutting fluid mixed with finer chips and impurities (such as silt, powder) will enter the interior of the first water tank 6.
[0029] The corners of the transverse end box body 62 of the first water tank 6 are arranged as arc surfaces 64, facilitating the guiding flow of the cutting fluid.
[0030] Self-circulating flushing devices are also provided at the corners of the transverse end box body 62 of the first water tank 6, including an inlet joint 8, a steel pipe 9, a tee joint 10, and an outlet joint 11.
[0031] The inlet joint 8 is fixed on the top of the transverse end box body 62 of the first water tank 6. The steel pipe 9 is connected below the inlet joint 8. The bottom of the steel pipe 9 is connected to the middle of the tee joint 10, and outlet joints 11 are respectively connected to both ends. A circulation water pump 12 is also provided on the transverse end box body 62 of the first water tank 6 and is connected to the inlet joint 8. By relying on the circulation water pump 12 to input cutting fluid to the upper part including the inlet joint 8, water flow can be generated at the lower outlet joint 11. In this way, the cutting fluid can circulate internally at a constant flow rate inside the transverse end box body 62, and powders and impurities (such as silt) in the transverse end box body 62 can be effectively collected and filtered even during the non-processing process of the machine tool.
[0032] The vortex separator 3 is arranged on one side of the chip discharge port 13 of the chip conveyor belt 1 of the chip discharger, and is used for filtering the cutting fluid for the second time. A lifting water pump 14 is arranged on the transverse end box body 62 of the first water tank 6 and is correspondingly connected to the vortex separator 3. The impurities such as iron powder and aluminum powder in the cutting fluid are filtered out by means of centrifugal vortex through the vortex separator 3.
[0033] The chip car 4 is arranged on one side of the transverse end box body 62 of the first water tank 6 and is located below the chip discharge port 13 of the chip discharger. The cutting fluid mixed with a large amount of waste chips generated after the machining of the machine tool is discharged onto the chip conveyor belt 1. Most of the solid waste chips are driven to the chip discharge port 13 by the chip conveyor belt 1 and the waste chips fall into the chip car 4. The main function of the chip car 4 is to collect waste chips.
[0034] On the opposite side corner of the liquid outlet 63 of the transverse end box body 62, a second water tank 7 with independent storage is separated by a partition plate 15. The bag filter 5 is arranged on the top of the second water tank 7 and is correspondingly connected to the vortex separator 3, and is used for filtering the cutting fluid for the third time. The bag in the bag filter 5 is mainly used for filtering impurities such as silt and sediment. At the same time, a hydraulic pressure detection device is also arranged in the bag filter 5. When the signal of the pressure detection device feeds back the pressure value to the limit, it means that the bag filter 5 has been blocked due to excessive accumulation of impurities, and the bag needs to be replaced in time. The cutting fluid filtered by the bag filter 5 will directly enter the second water tank 7. The clean cutting fluid filtered through these three layers will be separately stored in the second water tank 7 for use by the machine tool.
[0035] In summary, for the machine tool manufacturers, the multi-stage filtering machine tool water tank pointed out by the present utility model: the multi-stage filtering machine tool water tank can stably filter out the impurities and fine chips mixed in the cutting fluid, meets the use requirements of high-precision and high-end machine tools for the filtering water tank equipment, and reduces the occurrence of problems such as scratches on the surface of the processed products, tool wear, and the service life of the machine tool caused by the cutting fluid; for the machine tool users: it can greatly reduce the replacement frequency of the cutting fluid, reduce the environmental impact when the cutting fluid is discarded, and can greatly reduce the frequency of complicated water tank cleaning operations, realizing the long-term stable operation of the machine tool.
