[0001] This utility model relates to the field of emulsion filter technology, and in particular to an emulsion filter with an easy-to-replace filter element. Background Technology
[0002] Emulsions are high-performance metalworking fluids with wide applications in metal processing. They effectively prevent workpieces from rusting or undergoing chemical corrosion, and also effectively prevent microbial attack. However, over long-term use, emulsions often accumulate a large number of impurities, making reuse and recycling difficult.
[0003] A search revealed a Chinese patent publication number CN210874339U, which discloses a filter for waste emulsion, including a filter box and a pump body. The filter box is equipped with a first filter plate and a second filter plate. The device can effectively filter the emulsion through the first and second filter plates. At the same time, the opening and closing of the first, second and third switching valves can realize the replacement of old and new emulsions, ensuring lubrication and cooling effects.
[0004] However, when the waste emulsion enters the filter box, it falls directly from the feed pipe and impacts the surface of the first filter plate. The liquid flow impacts a single point for a long time, and the impact force will damage the filter plate and affect its service life. Utility Model Content

[0027] Example 1
[0028] An emulsion filter with an easy-to-replace filter element, such as Figures 1 to 4 As shown, the filter includes a filter box 3. Multiple elastic support legs 2 are fixed to the bottom outer wall of the filter box 3. One end of each elastic support leg 2 is connected to the same base 1. A feed pipe 4 is fixed to the top outer wall of the filter box 3. A vibration motor is installed on the bottom outer wall of the filter box 3. A guide pipe 5 is fixed to the top inner wall of the filter box 3. The top end of the guide pipe 5 is connected to the feed pipe 4. A buffer baffle 6 is fixed to the top side wall of the filter box 3. One end of the guide pipe 5 has a strip-shaped opening facing the buffer baffle 6. One end of the buffer baffle 6 is inclined to the ground. A guide support frame 8 is provided on the inner wall of the filter box 3. Multiple filter elements 7 are slidably connected to the inner wall of the guide support frame 8.
[0029] The filter box 3 has an inspection port on one side of its outer wall. A side plate 9 is fixed to the inner wall of the inspection port. A limit groove 16 is provided at the top of the inspection port. A positioning block that matches the limit groove 16 is fixed to the outer wall of the top of the side plate 9. A threaded cylinder is provided on the inner wall of the limit groove 16. A connecting hole that aligns with the threaded cylinder is provided on the outer wall of the positioning block. An installation screw 10 is provided on one side of the positioning block. One end of the installation screw 10 passes through the connecting hole and is threadedly connected to the threaded cylinder. A slot 15 is provided on the inner wall of the bottom of the inspection port. A connecting key is fixed to the bottom of the side plate 9. The connecting key is inserted into the slot 15 for a limit engagement.
[0030] The bottom of the filter box 3 is connected to a connecting pipe 11. A three-way pipe 12 is fixedly connected to one end of the connecting pipe 11 away from the filter box 3. Electric valves 13 are installed at both ends of the three-way pipe 12. One electric valve 13 is connected to the return pipe.
[0031] During emulsion filtration, the emulsion enters the guide pipe 5 from the feed pipe 4. The guide pipe 5 causes the emulsion to spray out from the strip-shaped opening towards the buffer baffle 6. The strip-shaped opening increases the coverage area of the emulsion. The buffer baffle 6 buffers the emulsion, reducing the impact force when it falls onto the surface of the filter element 7. After the emulsion falls onto the surface of the filter element 7, the filter element 7 filters the emulsion, removing impurities. At the same time, the vibration motor drives the entire filter box 3 to vibrate, accelerating the filtration process. The filtered emulsion accumulates in the filter box 3. During use, the electric valve 13 connected to the return pipe is opened, and the other electric valve 13 is closed, allowing the emulsion in the filter box 3 to flow along the connecting pipe 11 and the electric valve 13. When the filtered emulsion fails to meet the usage requirements after entering the return pipe, the electric valve 13 connected to the return pipe opens, and another electric valve 13 opens to release the emulsion in the filter box 3 and inject new emulsion into the filter box 3 to replace the emulsion. When the filter element 7 needs to be replaced, rotate the two mounting screws 10 to remove the mounting screws 10 and remove the side plate 9. At this time, multiple filter elements 7 can be pulled out from the guide support frame 8 for replacement. After replacement, the connecting key is inserted into the slot 15, the positioning block is inserted into the limiting groove 16 to position the side plate 9, and then the mounting screw 10 is passed through the connecting hole and connected to the threaded cylinder to fix the side plate 9.
[0032] By setting up a guide pipe 5 and a buffer baffle 6, the emulsion entering the filter box 3 from the feed pipe 4 is diffused and buffered, reducing the impact force of the emulsion falling on the surface of the filter element 7 and avoiding damage to the filter element 7 caused by long-term impact.
[0033] The filter element 7 can be removed by rotating the mounting screw 10, which is equipped with a guide support frame 8, a side plate 9, a mounting screw 10, a limiting groove 16, and a slot 15, making it easy to replace the filter element 7.
[0034] Example 2
[0035] An emulsion filter with easy-to-replace filter element is described in this embodiment, which is based on Embodiment 1 and makes the following improvements, such as... Figure 1 , Figure 4 As shown, a collection box 14 is fixed to the side wall of the filter box 3. Multiple discharge ports are opened on the side wall of the filter box 3 above one end of the filter element 7. A telescopic rod 18 is installed on the outer wall of the collection box 14. A sealing plate 17 is fixedly connected to the telescopic end of the telescopic rod 18. The sealing plate 17 is closed and cooperates with the multiple discharge ports. The end of the filter element 7 near the collection box 14 is inclined to the ground.
[0036] During filtration, impurities on the surface of filter element 7 accumulate at one end of filter element 7. After working for one end for a period of time, telescopic rod 18 moves the sealing plate 17 to one side, causing the sealing plate 17 to detach from the discharge port. The impurities on the surface of filter element 7 enter the collection box 14 for collection. Then, telescopic rod 18 pushes the sealing plate 17 to close the discharge port. When the impurities in the collection box 14 reach a certain amount, the collection box 14 is cleaned.
[0037] By incorporating a collection box 14, a sealing plate 17, and a telescopic rod 18, impurities on the surface of the filter element 7 can be guided into the collection box 14 for collection, facilitating centralized cleaning of the impurities.
[0038] Working principle: When filtering emulsion, the emulsion enters the guide pipe 5 from the feed pipe 4. The guide pipe 5 causes the emulsion to spray out from the strip-shaped opening towards the buffer baffle 6. The strip-shaped opening increases the coverage area of the emulsion. The buffer baffle 6 buffers the emulsion, reducing the impact force when the emulsion falls on the surface of the filter element 7. After the emulsion falls on the surface of the filter element 7, the filter element 7 filters the emulsion, removing impurities. At the same time, the vibration motor drives the filter box 3 to vibrate as a whole, accelerating the filtration. The filtered emulsion accumulates in the filter box 3. During use, the electric valve 13 connected to the return pipe is opened, and the other electric valve 13 is closed, allowing the emulsion in the filter box 3 to enter the return pipe along the connecting pipe 11 and the electric valve 13. When the filtered emulsion does not meet the usage requirements, the electric valve 13 connected to the return pipe is opened, and the other electric valve 13 is opened, releasing the emulsion in the filter box 3. The new emulsion is injected into the filter box 3 to replace the emulsion. When the filter element 7 needs to be replaced, the two mounting screws 10 are turned to remove the mounting screws 10 and the side plate 9 is removed. At this time, multiple filter elements 7 can be pulled out from the guide support frame 8 and the filter elements 7 are replaced. After the replacement is completed, the connecting key is inserted into the slot 15, the positioning block is inserted into the limiting groove 16 to position the side plate 9, and then the mounting screw 10 is passed through the connecting hole and connected to the threaded cylinder to fix the side plate 9. During filtration, the impurities on the surface of the filter element 7 are collected at one end of the filter element 7. After working for a period of time, the telescopic rod 18 drives the sealing plate 17 to move to one side, so that the sealing plate 17 is separated from the discharge port. The impurities on the surface of the filter element 7 enter the collection box 14 for collection. Then the telescopic rod 18 pushes the sealing plate 17 to close the discharge port. When the impurities in the collection box 14 reach a certain amount, the collection box 14 is cleaned.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
