Description

Technical Field

[0001] This utility model relates to the field of electrical discharge machines, and more specifically, it relates to a waste liquid treatment device for electrical discharge machines. Background Technology

[0002] An electrical discharge machining (EDM) machine is a type of machining equipment mainly used for EDM processing. It is widely used in the manufacture of various metal molds and mechanical equipment. The EDM machine is a special processing method that uses the electro-erosion effect generated by pulse discharge between two electrodes immersed in a working fluid to remove conductive materials. During the use of an EDM machine, a large amount of working fluid is used. However, the waste fluid after cutting contains a large amount of debris eroded from the material, which makes the working fluid unusable and results in a large consumption of working fluid.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waste liquid treatment device for EDM machines.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waste liquid treatment device for an EDM machine, comprising a base and a tray, the tray being rotatably connected to the base, and a collection frame disposed on the base, the bottom of the tray extending into the collection frame, a push plate being slidably connected in the horizontal direction inside the collection frame, a filter frame disposed inside the collection frame, the filter frame being open on the side near the push plate, the filter frame having multiple filter holes at its bottom, a receiving opening for accommodating the bottom of the filter frame being opened on the inner bottom surface of the collection frame away from the push plate, a gap existing between the outer bottom surface of the filter frame and the inner bottom surface of the receiving opening, a water outlet groove communicating with the filter holes being opened on the inner bottom surface of the receiving opening, a water outlet pipe communicating with the water outlet groove being fixedly connected to the collection frame, a valve being installed on the water outlet pipe, and a liquid collection frame being placed at the bottom of the water outlet pipe.

[0006] Preferably, an installation plate is fixedly connected to the bottom surface of the filter frame. The installation plate is located near the opening of the filter frame, and a storage cavity is formed between the installation plate and the inner wall of the filter frame. Multiple grooves are provided on the installation plate, and the grooves are connected to the filter holes. A baffle is fixedly connected to the inner wall of the end of the groove. Both sides of the baffle form gaps with the inner sidewall of the groove. When the bottom of the filter frame is accommodated in the receiving opening, the baffle and the bottom surface of the collection frame are at the same horizontal plane.

[0007] Preferably, the horizontal height of the bottom wall of the storage cavity is less than the horizontal height of the top surface of the mounting plate, and the bottom wall of the storage cavity is provided with multiple liquid outlet holes that communicate with the receiving port.

[0008] Preferably, two anti-clogging plates are fixedly connected to the inner wall of the collection frame. The two anti-clogging plates are located on both sides of the push plate, and the anti-clogging plates are in contact with the push plate. The anti-clogging plates are in contact with the side wall of the filter frame opening, and the side wall of the anti-clogging plate near the push plate is set in the same plane as the inner side wall of the filter frame.

[0009] Preferably, two abutment strips are fixedly connected to the inner wall of the receiving port, and the two abutment strips are used to abut against the outer bottom surface of the filter frame, and the filter frame abuts against the inner wall of the receiving port.

[0010] Preferably, a hydraulic rod is installed on the outer wall of the collection frame near the push plate, and the telescopic end of the hydraulic rod passes through the outer wall of the collection frame and is fixedly connected to the push plate.

[0011] Preferably, an inclined mesh plate is fixedly connected to the inner wall of the liquid collection frame. The height of the inclined mesh plate on the side closer to the water outlet pipe is less than the height of the side of the inclined mesh plate away from the water outlet pipe, and one end of the water outlet pipe is located directly below the inclined mesh plate.

[0012] In summary, this utility model has the following beneficial effects: This solution, by setting a pusher plate, a filter frame, and a liquid collection frame on the collection frame, allows the following: When the EDM machine uses working fluid to electro-etch the material on the tray, the debris removed from the material and the working fluid fall and are stored in the collection frame. Then, by moving the pusher plate towards the filter frame, the pusher plate pushes the debris and working fluid forward until both are pushed into the filter frame. At this point, the working fluid flows through the filter holes into the inlet and outlet tank. Then, by opening the valve, the working fluid flows out of the outlet tank and into the liquid collection frame through the outlet pipe, while the debris is contained in the filter frame. The debris in the filter frame and the working fluid in the liquid collection frame are then processed separately, preventing debris from mixing with the working fluid and thus reducing the consumption of the working fluid.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] A waste liquid treatment device for an EDM machine, such as Figures 1 to 5As shown, the device includes a base 1 and a tray 2. The tray 2 is connected to the base 1 via a motor. It also includes a collection frame 3 placed on the base 1. The top of the collection frame 3 is open. The tray 2 is located above the collection frame 3, and its bottom extends into the collection frame 3. A push plate 4 is slidably connected to the collection frame 3 in a horizontal direction. A filter frame 5 is installed inside the collection frame 3. The side of the filter frame 5 closest to the push plate 4 is open. Multiple filter holes 6 are formed at the bottom of the filter frame 5. A receiving opening 7 is formed on the inner bottom surface of the collection frame 3 away from the push plate 4 to accommodate the bottom of the filter frame 5. There is a gap between the outer bottom surface of the filter frame 5 and the inner bottom surface of the receiving opening 7. A water outlet trough 8 is connected to the filter holes 6. A water outlet pipe 9 connected to the water outlet trough 8 is welded to the collection frame 3. A valve is installed on the water outlet pipe 9. A liquid collection frame 10 is placed at the bottom of the water outlet pipe 9. An installation plate 11 is welded to the bottom surface of the filter frame 5. The installation plate 11 is located near the opening of the filter frame 5. A storage cavity 12 is formed between the installation plate 11 and the inner wall of the filter frame 5. Multiple grooves 13 are opened on the installation plate 11. The grooves 13 are connected to the filter holes 6. The filter holes 6 pass through the bottom surface of the grooves 13 and the bottom of the filter frame 5 respectively. A baffle 14 is welded to the inner wall of the end of the groove 13. Both sides of the baffle 14 form gaps with the inner sidewall of the groove 13. Above the filter hole 6, the baffle 14 is flush with the mounting plate 11. When the bottom of the filter frame 5 is accommodated in the receiving port 7, the baffle 14 and the bottom surface of the collection frame 3 are at the same level. The horizontal height of the bottom wall of the storage cavity 12 is less than the horizontal height of the top surface of the mounting plate 11. The bottom wall of the storage cavity 12 has multiple outlet holes 15 that communicate with the receiving port 7. Two anti-clogging plates 16 are welded to the inner wall of the collection frame 3. The two anti-clogging plates 16 are located on both sides of the push plate 4 and are in contact with the side wall of the push plate 4. The anti-clogging plates 16 are in contact with the side wall of the opening of the filter frame 5. The side wall of the anti-clogging plate 16 near the push plate 4 is flush with the inner side wall of the filter frame 5. Two abutment strips 17 are welded to the inner wall of the receiving port 7. The two abutment strips 17 are used to abut against the outer bottom surface of the filter frame 5. The filter frame 5 abuts against the inner wall of the receiving port 7. A hydraulic rod 18 is installed on the outer wall of the collecting frame 3 near the push plate 4. The hydraulic rod 18 is driven by an electric motor to extend and retract the hydraulic pipe extension end. The extension end of the hydraulic rod 18 passes through the outer wall of the collecting frame 3 and is welded to the push plate 4. An inclined mesh plate 19 is welded to the inner wall of the liquid collecting frame 10. Multiple meshes are opened on the inclined mesh plate 19. The height of the side of the inclined mesh plate 19 near the water outlet pipe 9 is less than the height of the side of the inclined mesh plate 19 away from the water outlet pipe 9. One end of the water outlet pipe 9 is located directly below the inclined mesh plate 19.

[0022] The user first places the filter frame 5 into the receiving port 7 until the two contact strips 17 abut against the outer bottom surface of the filter frame 5. At this time, the outer bottom wall of the filter frame 5 is in contact with the inner wall of the receiving port 7, and the opening of the filter frame 5 faces the push plate 4. At the same time, the top surface of the baffle 14 is at the same level as the inner bottom surface of the collection frame 3, so that the filter frame 5 can be placed in the collection frame 3. Then, when the user operates the EDM machine and uses the working fluid to perform electro-erosion on the material placed on the tray 2, the debris removed from the material and the working fluid will fall and be stored in the collection frame 3. At this time, the extension end of the hydraulic rod 18 is extended by the motor. When the extension end of the hydraulic rod 18 is extended, it drives the push plate 4. As the push plate 4 moves toward the filter frame 5, its two side walls come into contact with the anti-clogging plates 16 located on both sides of the push plate 4. The push plate 4 also pushes debris and working fluid to move as it moves. Since the anti-clogging plates 16 are set on the same plane as the inner side wall of the filter frame 5, debris is prevented from remaining between the side wall of the push plate 4 and the inner side wall of the collection frame 3. The debris and working fluid are pushed into the filter frame 5 by the push plate 4. At this time, the two side walls of the push plate 4 are no longer in contact with the two anti-clogging plates 16, and the bottom surface of the push plate 4 is in contact with the top surface of the mounting plate 11 and the baffle plate 14. At the same time, the two side walls of the push plate 4 are in contact with the two inner side walls of the filter frame 5.

[0023] When the pusher plate 4 pushes the debris and working fluid into the filter frame 5, the working fluid first flows downward into the groove 13 through the gap formed by the baffle plate 14 and the inner sidewalls of the groove 13. The debris does not pass through the gap formed by the baffle plate 14 and the inner sidewalls of the groove 13. Then, the working fluid flows downward into the receiving port 7 through the filter hole 6 in the groove 13, and then flows into the outlet tank 8 through the receiving port 7. The valve is then opened, allowing the working fluid to flow through the outlet tank 8 to the outlet pipe 9, and then into the collection frame 10 through the outlet pipe 9. The baffle plate 14 intercepts the debris, preventing the baffle plate 14 from falling directly into the collection frame 10. To prevent the filter holes 6 from becoming clogged in the groove 13, thus affecting the flow of working fluid from the filter holes 6 to the receiving port 7, the extension end of the adjusting hydraulic rod 18 is extended to drive the push plate 4 to move, causing the push plate 4 to continue pushing the debris until it is pushed into the storage cavity 12. Through the liquid outlet 15 on the bottom wall of the storage cavity 12, the remaining working fluid from the push plate 4 can flow from the liquid outlet 15 through the receiving port 7, the water outlet 8, and the water outlet pipe 9 into the collection frame 10, so that the working fluid can be collected in the collection frame 10 and the debris can be collected in the storage cavity 12 in the filter frame 5. This can be achieved by shortening the adjustment... The telescopic end of the hydraulic rod 18 drives the push plate 4 to move until the push plate 4 disengages from the filter frame 5. Then, the user holds the top of the filter frame 5 and pulls it upward. At this time, the bottom of the filter frame 5 does not abut against the contact strip 17, allowing the filter frame 5 and the debris inside the filter frame 5 to be removed from the top of the collection frame 3. Because the horizontal height of the bottom wall inside the storage cavity 12 is less than the horizontal height of the top surface of the mounting plate 11, the debris abuts against the side wall of the mounting plate 11. This prevents the debris from falling directly out of the filter frame 5 during the upward removal of the filter frame 5. Afterward, the debris in the filter frame 5 and the working fluid in the collection frame 10 are treated separately to prevent the debris from mixing with the working fluid. To prevent the working fluid from being reused, and to reduce its consumption, when the working fluid flows from the outlet pipe 9 to the collection frame 10, it comes into contact with the inclined screen plate 19. Because the height of the side of the inclined screen plate 19 closest to the outlet pipe 9 is less than the height of the side of the inclined screen plate 19 furthest from the outlet pipe 9, the working fluid can flow through the mesh on the inclined screen plate 19 into the collection frame 10. The inclined screen plate 19 can also filter out debris remaining in the working fluid, so that the debris is contained in the space enclosed by the inclined screen plate 19 and the inner wall of the collection frame 10. The small amount of debris attached to the inclined screen plate 19 can then be processed.
