Description

Technical Field

[0001] The utility model relates to a chip removal and filtering system for a machine tool, belonging to the technical field of machine tool equipment. Background Art

[0002] In the cutting process of machine tools, in order to reduce 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 scraper chip conveyor is a common device used to remove these liquid-containing chips and transport cutting fluid. The magnetic scraper chip conveyor scrapes the chips from the bottom of the chip conveyor through the scraper, and uses magnetic materials to absorb iron chips to achieve the discharge of waste chips and the separation of cutting fluid.

[0004] However, the magnetic scraper conveyor mainly relies on the magnetic material inside it to absorb iron debris. For larger iron chips, it can effectively absorb and separate them. In the cutting process, in addition to iron chips, a large amount of non-iron chips and tiny iron particles are also generated. These particles may not be completely absorbed by the magnetic scraper conveyor due to their small size or weak magnetism.

[0005] Therefore, although the magnetic scraper conveyor can effectively remove some iron chips, a large amount of chips and pollutants will still remain in the separated cutting fluid. Such cutting fluid often cannot be recycled because it still contains a large amount of impurities and pollutants and needs to be further processed before it can be used again.

[0006] In addition, the magnetic scraper chip conveyor requires manual operation during use, and the chips generated by the machine tool during the cutting process need to be regularly transported to the magnetic scraper chip conveyor for cleaning and separation. Utility Model Content

[0008] The technical solution provided by the utility model is as follows: a machine tool chip removal and filtering system, comprising a magnetic scraper conveyor, a screw conveyor, a primary water tank, a secondary water tank and a connecting channel, wherein the connecting channel is arranged between the primary water tank and the secondary water tank, and the screw conveyor is installed above the connecting channel; the liquid outlet of the screw conveyor is connected to the magnetic scraper conveyor; the magnetic scraper conveyor is installed close to the primary water tank, and a water outlet is provided on the shell of the magnetic scraper conveyor, the water outlet is connected to the primary water tank, a primary filter is provided between the primary water tank and the connecting channel, and a secondary filter is provided between the connecting channel and the secondary water tank.

[0009] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: the machine tool chip removal and filtration system of the utility model integrates a magnetic scraper conveyor, a screw conveyor, a primary water tank, a secondary water tank and a connecting channel. The system first collects and conveys the cutting fluid generated by the machine tool to the magnetic scraper conveyor through the screw conveyor, and performs the first cleaning treatment on the magnetic scraper conveyor, and uses magnetic force to effectively remove the iron impurities in the chips. The cleaned cutting fluid passes through the primary filter and the secondary filter in turn to achieve further filtration to ensure the purity of the cutting fluid. Finally, the cutting fluid that has been filtered at two levels is circulated back to the cooling system of the machine tool, realizing the recycling of the cutting fluid, saving water resources and reducing environmental pollution. In addition, the system installs the screw conveyor above the connecting channel, which greatly saves working space and improves the working efficiency of the entire system.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

This design enables the cutting fluid to be automatically and efficiently circulated without manual handling and transfer, thereby significantly reducing the risk of cutting fluid leakage. In addition, this layout also saves labor costs, improves the safety of the processing process, and effectively improves the overall work efficiency.

[0013] Furthermore, the primary water tank and the connecting channel are an integrated structure.

[0016] The beneficial effect of adopting the above further solution is that the communicating channel and the secondary water tank are connected by a flange, which can be easily disassembled and reinstalled, making it convenient for personnel to clean and maintain.

[0017] Furthermore, a filter screen frame is provided in the primary water tank, a drainage slot is provided on a side of the filter screen frame close to the screw conveyor, the drainage slot is connected to a water outlet provided on the shell of the magnetic scraper conveyor, and the secondary filter screen is arranged on the filter screen frame.

[0018] The beneficial effect of adopting the above further solution is that the setting of the filter frame can effectively intercept tiny particles and suspended matter in the cutting fluid, thereby improving the cleanliness of the cutting fluid.

[0019] Furthermore, an overflow baffle is provided in the communicating channel, the communicating channel is located below the overflow baffle, and the screw conveyor is arranged above the overflow baffle.

[0020] The beneficial effect of adopting the above further solution is that it prevents the unfiltered cutting fluid from overflowing into the bottom connecting channel due to the excessively high liquid level in the screw conveyor.

[0021] Furthermore, the screw conveyor includes a motor, a spiral shell and a spiral core. The spiral core is installed in the spiral shell. The top of the spiral shell is open. The motor is drivingly connected to the spiral core.

[0022] The beneficial effect of adopting the above further solution is that the spiral core rotates under the drive of the motor, and can efficiently transport the cutting fluid from the spiral shell to the magnetic scraper conveyor.

[0024] The beneficial effect of adopting the above further scheme is that the lifting pump is responsible for transporting the cutting fluid in the secondary water tank through the delivery pipe to the magnetic separation device for further filtration, so as to reduce manual maintenance and extend the use time of the cutting fluid. The powdery residue in this filtration is discharged into the slag receiving box, and the treated cutting fluid will pass through the connecting channel and finally re-enter the secondary water tank for collection.

[0025] Furthermore, it also includes a liquid supply pump, which is connected to the secondary water tank.

[0026] The beneficial effect of adopting the above further solution is that the liquid supply pump is used to supply the cutting fluid in the secondary water tank to the machine tool for circulation.

[0027] Furthermore, the mesh number of the primary filter is smaller than the mesh number of the secondary filter.
