Description

Technical Field

[0001] The utility model relates to an electrolyte filtering system, in particular to an ECM machine tool electrolyte filtering system. Background Art

[0002] The ECM electrolytic machine tool performs finishing on the workpiece surface by dissolving the anodic metal. The machining tool is the cathode (-) that works under the electric current. When it encounters the electrolyte, it can produce an anodic reaction, which can accurately remove the excess material on the surface of the workpiece (+). The electrolyte solution can transfer charge in the gap between the cathode and the workpiece, causing the electrons to be transferred from the workpiece, thereby removing the excess material on the surface. The material removed during processing must be filtered out of the electrolyte to maintain the constant quality of the electrolyte in the gap between the cathode and the workpiece. Moreover, after long-term use, the metal hydroxides and other impurities contained in the electrolyte continue to increase, which will increase the viscosity of the electrolyte and affect the flow of the electrolyte in the processing gap. In severe cases, a short circuit will occur, causing damage to the workpiece and the electrode. The commonly equipped filtration system either has a general filtration effect and a short filter life and a high replacement frequency, resulting in high production costs, while the filtration system with good effects is often large, requires a large area of ​​use, and is inconvenient to place.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The present embodiment is about the electrolyte filtration system of the ECM machine tool, including a primary water tank 3 and a secondary water tank 4 arranged according to the process classification. The primary water tank 3 performs coarse filtering on the untreated electrolyte in the previous process, and the secondary water tank 4 performs fine filtering on the electrolyte coarsely filtered by the primary water tank 3 in the subsequent process; the primary water tank 3 and the secondary water tank 4 are installed in a parallel arrangement. Compared with the traditional device, the present embodiment greatly saves the placement area, occupies a small area, and has a high placement flexibility.

[0022] In this embodiment, a primary filter tank 5 is formed inside the primary water tank 3, a primary coarse filter bag 6 is provided in the tank cavity of the primary filter tank 5, a reflux pipe joint 7 which is in communication with the tank cavity space of the primary filter tank 5 is provided above the primary water tank 3, and a filter circulation pump 8 which is in communication with the tank cavity space of the primary filter tank 5 is also provided above the primary water tank 3; a secondary precision filter 9 which is connected to the inner cavity of the secondary water tank 4 is installed above the secondary water tank 4.

[0023] Preferably, there are multiple first-level coarse filter bags 6, which are arranged in a line at intervals. The filtration accuracy of the first-level coarse filter bag 6 is 100 μm. The large particle impurities and iron hydroxide flocs in the electrolyte are effectively filtered through the first-level coarse filter bag 6. In addition, the first-level coarse filter bag 6 itself is easy to replace, and it is also convenient to clean the impurities in the first-level filter tank 5.

[0024] Preferably, the return pipe joint 7 is formed in a manner of providing an inflow path for untreated electrolyte from the outside, that is, in this embodiment, the untreated electrolyte from the outside flows into the primary water tank 3 through the return pipe joint 7 .

[0025] Preferably, the filter circulation pump 8 and the secondary precision filter 9 are connected by a circulation pipeline 10, and the circulation pipeline 10 provides a pipeline path for the circulation of electrolyte between the filter circulation pump 8 and the secondary precision filter 9. That is to say, the electrolyte that has been coarsely filtered in the primary water tank 3 is pumped into the secondary precision filter 9 through the circulation pipeline 10 under the action of the filter circulation pump 8.

[0026] Furthermore, several precision filter bags (not shown in the figure) are installed in the secondary precision filter 9. The filtration accuracy of the precision filter bags is 10μm. The secondary precision filter 9 and the several precision filter bags inside it are arranged to save space while ensuring the filtration area and flow rate, and will not occupy additional area. The simultaneous precision filtration of several precision filter bags also increases the life of a single precision filter bag and reduces the replacement frequency of the precision filter bags. It should be noted that the precision filter bag is a prior art and is not a technical feature that needs to be protected in this application, so it is not shown.

[0027] Preferably, a liquid supply pump 11 located on one side of the secondary precision filter 9 is installed above the secondary water tank 4 , and the liquid supply pump 11 is connected to the inner cavity of the secondary water tank 4 .

[0028] It also includes a cooling machine 1 connected to the secondary water tank 4 through a circulating cooling pipe 2.

[0029] Based on the above structure, when the electrolyte after fine filtration by the secondary precision filter 9 enters the secondary water tank 4, the filtered electrolyte is then provided with conveying kinetic energy by the liquid supply pump 11 for electrolysis and conduction. During this process, the cooler 1 circulates and cools the electrolyte in the secondary water tank 4 through the circulating cooling pipe 2.

[0030] In this way, the ECM machine tool electrolyte filtration system disclosed in the utility model performs primary and secondary filtration on the electrolyte through differentiated configuration. The primary filtration completed in the primary water tank 3 effectively filters the large particle impurities and iron hydroxide flocs in the electrolyte by coarse filtration, and the secondary filtration completed in the secondary water tank 4 finely filters the electrolyte after coarse filtration by fine filtration. The filtration effect is good, the replacement frequency is low, the overall system structure is compact, the footprint is small, and the supporting electrolytic equipment is more convenient to use.

[0031] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
