Description

Technical Field

[0001] The invention relates to the technical field of filtering systems, in particular to a working fluid high-efficiency circulating filtering system. Background Art

[0002] In equipment that uses working fluid for various machining operations, in order to maintain the circulation of the working fluid and reduce downtime for cleaning, manufacturers tend to equip relatively simplified working fluid filtration systems. However, although this design compromise meets basic production needs to a certain extent, it also brings problems that cannot be ignored. Specifically, these simplified filtration systems often find it difficult to effectively intercept all impurities when performing filtration tasks, resulting in a large amount of fine slag metal chips, tiny ash and other suspended particles remaining in the filtered working fluid.

[0003] These impurities that have not been completely removed will not only cause continuous wear and tear on the precision parts inside the machine tool during the circulation of the working fluid, shortening their service life, but will also accelerate the passivation process of the tool, increase the frequency of tool replacement, and thus affect the machining accuracy and surface quality of the workpiece. In addition, after long-term contact with the working fluid containing a large amount of impurities, the fixture will also suffer from problems such as inaccurate positioning and reduced clamping force due to increased wear, further affecting the overall effect of machining.

[0004] What is more serious is that due to the high impurity content in the working fluid, its lubrication, cooling and rust prevention properties will be greatly reduced, forcing companies to replace the working fluid more frequently to keep the production line running normally. This not only increases the amount of working fluid used, but also shortens its actual use cycle, which invisibly increases the difficulty of controlling production costs. Especially in the current context of increasingly fierce market competition and shrinking profit margins, the additional expenses brought about by frequent replacement of working fluids are undoubtedly a major challenge to the profitability of enterprises.

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1 As shown, the present invention comprises a collection and storage box 1, a water pump 3, a filter box 4 and a constant temperature liquid collection box 8.

[0019] The storage box 1 is of a closed type, and a horizontally arranged liquid inlet pipe is provided on the side wall of the storage box 1. The liquid inlet pipe is connected to the working liquid pool 11 through an input pipe, and a valve is installed between the liquid inlet pipe and the input pipe; a liquid outlet pipe is provided on the storage box 1, and the liquid outlet pipe is connected to the water pump 3 through a water pipe. A filter screen is installed inside the storage box 1, and the filter screen is located below the liquid outlet pipe of the storage box 1. The filter screen can prevent the solid matter in the working liquid from clogging the water pump 3. When the water pump 3 stops pumping, the water flow can backwash the filter screen.

[0020] A drain valve is provided at the lower end of the storage box 1, and the drain valve is used to discharge the solid matter accumulated in the storage box 1 regularly or at any time.

[0021] The water pump 3 is connected to the storage box 1 through a connecting pipe. In the optimization scheme, a pressure gauge 2 is set between the water pump 3 and the storage box 1 to monitor the pressure of the liquid inside the connecting pipe. When the pressure exceeds the rated value, it means that the filter screen in the storage box 1 is blocked, the pump is stopped and an alarm is sounded. The valve at the end of the liquid inlet pipe through the storage box 1 needs to be closed, and the drain valve is opened to drain the solid matter in the storage box 1.

[0022] The water pump 3 is connected to the input end of the filter box 4 through a connecting pipe. The filter box 4 is provided with multiple layers of filter screens. The multiple layers of filter screens improve the filtering accuracy layer by layer, thereby preventing impurities in a certain layer from clogging the filter screen.

[0023] A vibrator 5 is installed at the lower end of the filter box 4 , and the vibrator 5 can drive the filter box 4 to vibrate, thereby accelerating the filtering speed of the filter box 4 .

[0024] A magnetic absorption collector 6 is arranged below the vibrator 5, and the magnetic absorption collector 6 can eliminate metal particles in the micro-liquid, thereby further purifying the working fluid.

[0025] The output end of the filter box 4 is connected to the input end of the demagnetizer 7 through a connecting pipe. The demagnetizer 7 can eliminate the magnetism of residual micro-metal particles in the working fluid.

[0026] The output end of the demagnetizer 7 is connected to the input end of the constant temperature liquid collecting tank 8 through a connecting pipe, and the output end of the constant temperature liquid collecting tank 8 is connected to the working liquid pool 11 through a loop pipe.

[0027] The input end of the constant temperature liquid collecting tank 8 is connected to the pure water storage tank 9 and the raw liquid storage tank 10 through connecting pipes, and a thermometer and a concentration meter are arranged inside the constant temperature liquid collecting tank 8. The technical indicators of the automatically refluxed working fluid are monitored by the concentration meter and the thermometer. The deficiency of pure water or raw liquid is calculated by the difference of the concentration meter and fed back to the pure water storage tank 9 and the raw liquid storage tank 10, so that pure water or raw liquid can be dynamically added to the constant temperature liquid collecting tank 8 in a timely manner.

[0028] In the optimized solution, the concentration meter is located at the output end of the constant temperature liquid collecting tank 8.

[0029] In the optimization scheme, a stirrer is installed in the constant temperature liquid collecting box 8, and the stirrer can accelerate the mixing speed of the working liquid and the pure water or the original liquid.

[0030] The operation process is as follows: when using the present invention, the water pump 3 first draws the working fluid into the storage box 1. After preliminary filtration, the working fluid enters the filter box 4 for layered filtration, and the metal particles in the micro-liquid are eliminated by the magnetic absorption collector 6 to further purify the working fluid. The magnetism of the residual micro-metal particles in the working fluid is eliminated by the demagnetizer 7, and then the working fluid enters the constant temperature liquid collection box 8 to add pure water or stock liquid, and finally discharged into the working fluid pool 11.

[0031] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
