Description

Technical Field

[0001] This utility model relates to the field of electrochemical processing technology, specifically, to an electrolyte filtration device for metal electrolytic cutting. Background Technology

[0002] Electrochemical machining (ECM) is a processing method that removes metallic materials through electrochemical reactions. Its basic principle is based on electrolysis, where an electric current in an electrolyte causes a redox reaction on the workpiece surface, thereby removing the metal. During ECM, the workpiece and electrodes are connected by an electrolyte; as the current flows, the metal surface is electrolyzed into ions and dissolved, forming tiny metal particles, thus achieving material removal.

[0003] In existing processing techniques, the electrolyte is typically recycled, necessitating filtration to remove impurities introduced during processing. This is usually achieved using multiple removable filters, requiring only screen replacement by the operator. However, in current filtration equipment, the filters are typically fixed within the electrolyte flow channel. To prevent loosening, multiple points of fixation are necessary to ensure filter stability. Because filters are prone to clogging, frequent replacement is required; however, the numerous fixing points make replacement cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an electrolyte filtration device for metal electrolytic cutting, which solves the problem of cumbersome filter replacement in existing equipment.

[0005] This utility model is achieved through the following technical solution: an electrolyte filtration device for metal electrolytic cutting, comprising:

[0006] A filter box for holding electrolyte, wherein the filter box is provided with an inlet pipe and an outlet pipe;

[0007] A graded filtration assembly is used to filter electrolyte. The graded filtration assembly includes multiple filter plate units arranged along the electrolyte flow direction. Each filter plate unit includes a filter plate and a limiting mounting strip. The limiting mounting strip is installed on the filter box. Each filter plate includes a filter frame and a filter screen. The filter frame includes a main frame and a sub-frame. The filter screen is installed between the sub-frame and the main frame. The filter frame is inserted into the limiting mounting strip for fixation.

[0008] To better realize this utility model, the filter plate further includes a handle, which is mounted on the main frame.

[0009] To better realize this utility model, the handle is further slidably connected to the main frame, a first spring is provided between the handle and the main frame, and the filter plate unit also includes a limiting member for limiting the filter plate.

[0010] To better realize this utility model, the limiting member further includes a fixed limiting block installed on the limiting mounting strip and a limiting slider slidably connected to the handle. A second spring is provided between the limiting slider and the handle, and the fixed limiting block cooperates with the limiting slider.

[0011] To better realize this utility model, the filter box is further provided with a drain pipe, a collection inclined block is installed in the filter box, and the filter plate is attached to the surface of the collection inclined block.

[0012] To better realize this utility model, further, along the electrolyte flow direction, the top height of the filter plates in the plurality of filter plate units gradually decreases.

[0013] To better realize this utility model, the filter box further includes a box body and a box cover, the box cover being detachably and airtightly connected to the box body; a transparent observation window is provided on the box cover.

[0014] To better realize this utility model, a water immersion sensor is further installed on the top of the main frame.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] (1) By setting a limiting installation strip to cooperate with the main frame and the sub-frame, this utility model can not only fix the filter screen well and prevent the filter screen from falling off due to hydraulic impact during filtration, but also simplify the disassembly and assembly steps of the filter screen.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1:

[0028] This embodiment provides an electrolyte filtration device for metal electrolytic cutting, specifically as follows: Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, it includes:

[0029] A filter box is used to hold electrolyte. The filter box is equipped with an inlet pipe 103 and a drain pipe 104. The electrolyte flows into the filter box from the inlet pipe 103 and then flows out from the drain pipe 104.

[0030] A graded filtration assembly is used to filter electrolyte. The graded filtration assembly includes multiple filter plate units arranged along the electrolyte flow direction. Each filter plate unit includes a filter plate and a limiting mounting strip 106. The limiting mounting strip 106 is installed on the filter box. Each filter plate includes a filter frame and a filter screen 105. The filter frame includes a main frame 110 and a secondary frame 115. The filter screen 105 is installed between the secondary frame 115 and the main frame 110. The filter frame is inserted into the limiting mounting strip 106 for fixation.

[0031] Along the electrolyte flow direction, the filtration accuracy of filter screen 105 increases. When installing the filter plate, select the corresponding filter screen 105, place it on the main frame 110, and then press the secondary frame 115 onto the filter screen 105, ensuring that the edges and corners of the filter screen 105 are not exposed. Then, insert the main frame 110 and the secondary frame 115 into the limiting installation strip 106. Since the reserved groove width of the limiting installation strip 106 is fixed, when the filter frame carrying the filter screen 105 is inserted, the main frame 110 and the secondary frame 115 are limited by the limiting installation strip 106 and tightly press the filter screen 105, ensuring that the filter screen 105 will not fall off during use. When it is necessary to replace the filter screen 105, pull out the filter frame. At this time, the secondary frame 115 can be removed to replace the filter screen 105. Then repeat the above steps to install. The filter screen 105 can be one of stainless steel filter screen, nylon filter screen, polypropylene filter screen, or polytetrafluoroethylene filter screen. When the electrolyte flows in from the inlet pipe 103, it first passes through a filter plate unit with reduced precision to filter out coarse impurities. Then, it passes through the filter plate units one by one, filtering out most of the impurities in a progressive manner, thus performing preliminary purification of the recovered electrolyte.

[0032] By setting the limiting installation strip 106 to cooperate with the main frame 110 and the sub-frame 115, the filter screen 105 can be fixed well, preventing the filter screen 105 from falling off due to hydraulic impact during filtration. It can also simplify the disassembly and assembly steps of the filter screen 105, which only needs to be clamped by the main frame 110 and the sub-frame 115, making it convenient for staff to replace.

[0033] Example 2:

[0034] This embodiment further extends the above embodiment, specifically as follows: Figures 3-5 As shown, the filter plate also includes a handle 109, which is mounted on the main frame 110. When the filter screen 105 needs to be replaced, the operator can lift the filter plate by holding the handle 109, providing a point of leverage for easy handling of the filter plate.

[0035] Furthermore, the handle 109 is slidably connected to the main frame 110, and a first spring 111 is provided between the handle 109 and the main frame 110. The filter plate unit also includes a limiting member, which is used to limit the filter plate.

[0036] To facilitate the cleaning of sedimented impurities within the filter box, the limiting installation strips 106 are only installed on both sides of the filter box, not at the bottom. This prevents the limiting installation strips 106 from obstructing the cleaning process. When installing the filter plate, press down the main frame 110 until the bottom of the filter plate contacts the bottom of the filter box. Then, continue pressing down on the handle 109. The first spring 111 is compressed, and the limiting component then limits the handle 109. Under the elastic force of the first spring 111, the filter plate is kept pressed against the bottom of the filter box, thus preventing impurities from flowing from the bottom of the filter plate.

[0037] Furthermore, the limiting component includes a fixed limiting block 112 mounted on the limiting mounting strip 106 and a limiting slider 113 slidably connected to the handle 109. A second spring 114 is provided between the limiting slider 113 and the handle 109, and the fixed limiting block 112 cooperates with the limiting slider 113.

[0038] The specific limiting principle is as follows: When the handle 109 is continuously pressed down, the lower inclined surface of the limiting slider 113 contacts the fixed limiting block 112. At this time, the limiting slider 113 is subjected to the force of the retracting handle 109, and the second spring 114 is compressed until the limiting slider 113 passes the fixed limiting block 112. Under the elastic force of the second spring 114, the limiting slider 113 pops out. At this time, the force of pressing down the handle 109 is removed. Under the elastic force of the first spring 111, the upper inclined surface of the limiting slider 113 presses against the fixed limiting block 112, but the second spring 114 will not be compressed, thus completing the limiting of the filter plate and ensuring that the bottom of the filter plate is pressed on the filter box.

[0039] Furthermore, a drain pipe 102 is provided on the filter box, and a collection inclined block 107 is installed in the filter box, with the filter plate attached to the surface of the collection inclined block 107.

[0040] Therefore, when cleaning the filter box, stop the electrolyte input at the inlet pipe 103, remove all filter plates, and since there is a collecting inclined block 107, the precipitated impurities will flow to the drain pipe 102 under the guidance of the slope of the collecting inclined block 107, and then be discharged from the drain pipe 102, thus improving the cleaning efficiency.

[0041] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0042] Example 3:

[0043] This embodiment further extends the above embodiment, specifically as follows: Figure 2 As shown, due to prolonged filtration, some filter screens 105 may become clogged. To independently separate each filtration area, the top height of the filter plates in the multiple filter plate units gradually decreases along the electrolyte flow direction. Figure 2If the middle filter 105 becomes clogged, the electrolyte in the corresponding area will begin to flow across the filter plate to the next filtration area. Since the previous filter plate is higher, the electrolyte will not flow back to the previous filtration area. At the same time, since the next filtration area is lower, the electrolyte that has crossed the middle filter plate will flow directly to the next area. The two areas will not be connected.

[0044] Furthermore, the filter box includes a box body 101 and a box cover 108, the box cover 108 being detachably and airtightly connected to the box body 101; the box cover 108 is provided with a transparent observation window. Personnel can observe through the observation window whether there is overflow at the top of each filter screen 105, thereby deciding whether to replace the filter screen 105.

[0045] In another specific embodiment, a water immersion sensor is installed on the top of the main frame 110. When the filter screen 105 becomes clogged, the electrolyte overflows to the top of the filter plate, triggering the water immersion sensor to issue an alarm and prompt the operator to replace it.

[0046] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
