Description

Technical Field

[0001] This utility model relates to the field of machine tool processing equipment technology, and in particular to a line gap type negative pressure chip removal filter. Background Technology

[0002] Linear-gap filter elements are a technology that uses a precision-structured slit structure, typically composed of parallel-arranged metal wires or a filter screen, combined with the principle of negative pressure suction to achieve solid-liquid separation. The working principle is that cutting fluid passes through the tiny gaps in the filter element under negative pressure, while larger metal debris is trapped on the filter element surface, thus achieving liquid purification and recovery. This technology is widely used in machine tool coolant treatment systems due to its compact structure, high filtration accuracy (capable of intercepting micron-sized particles), and continuous operation.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Existing wire-gap filter elements are prone to adhering to high-viscosity cutting fluid or hard metal particles. Traditional scraping methods using fixed scrapers are difficult to completely remove impurities, and the effect of removing debris from the surface of wire-gap filter elements is limited. As debris accumulates on the surface of wire-gap filter elements, the filtration efficiency of wire-gap filter elements decreases significantly over time, requiring frequent shutdowns to clean the filter elements, which affects the continuity of production. Utility Model Content

The various technical effects of the preferred solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention provides a line gap type negative pressure chip removal filter device, which includes a filter assembly for treating cutting fluid.

[0026] This invention provides a line-gap negative pressure chip removal filter that can quickly separate chips and liquid in cutting fluid, and simultaneously peel off metal chips and particles attached to the surface of the filter assembly, thereby preventing filter assembly blockage, reducing the frequency of manual cleaning, optimizing liquid recovery efficiency, and extending the service life of the filter assembly.

[0027] The following is combined Figures 1-4 The technical solution provided by this utility model will be described in more detail.

[0028] This utility model provides a line gap type negative pressure chip removal filter device, including a filter assembly 1 for treating cutting fluid. A scraping assembly 2 is installed on the upper end of the filter assembly 1. The scraping assembly 2 is used to scrape off the debris attached to the surface of the filter assembly 1 when the filter assembly 1 treats the cutting fluid.

[0029] This utility model provides a line-gap type negative pressure chip removal filter device, including a filter assembly 1 for treating cutting fluid. A scraping assembly 2 is installed on the upper end of the filter assembly 1. The scraping assembly 2 is used to scrape off the chips attached to the surface of the filter assembly 1 when the filter assembly 1 treats the cutting fluid.

[0030] In some embodiments of this utility model, the scraping component 2 includes a support shell 201, a slide rail 202, a vertical plate 203, and a fixing plate 204. The support shell 201 and the slide rail 202 are both fixedly installed on the upper end of the filter component 1. The slide rail 202 is located inside the support shell 201. The vertical plate 203 and the fixing plate 204 are both fixedly installed on the upper end of the filter component 1. The vertical plate 203 and the fixing plate 204 are located on both sides of the slide rail 202.

[0031] A sliding block 205 is slidably connected to the upper external end of the slide rail 202. A set of springs 206 is fixedly connected to the side of the upright plate 203 near the slide rail 202. The front end of the set of springs 206 is fixedly connected to one side of the sliding block 205. A connecting rod 207 is fixedly connected to one side of the sliding block 205. The connecting rod 207 includes a vertical rod part and a horizontal rod part. A scraper 208 is fixedly connected to the end of the horizontal rod part of the connecting rod 207 away from the sliding block 205. The upper end of the scraper 208 is disposed on the filter assembly 1. A first motor 209 is fixedly installed at the middle of the upper end of the support shell 201. The output end of the first motor 209 penetrates the support shell 201, and an elliptical plate 210 is fixedly connected to the output end of the first motor 209. The outer wall of the elliptical plate 210 is attached to the middle of the side of the sliding block 205 away from the springs 206.

[0032] Furthermore, during the filtration process of filter assembly 1, a large amount of solid impurities such as metal debris will adhere to the surface of filter assembly 1. At this time, the output end of the first motor 209 drives the elliptical plate 210 to rotate inside the support shell 201. The outer wall of the elliptical plate 210 will continuously impact the side wall of the sliding block 205. Since there is a spring 206 limiting one end of the sliding block 205, the sliding block 205 will continuously reciprocate on the upper end of the slide rail 202 under the continuous impact of the elliptical plate 210. This will cause the scraper 208 fixedly connected to the connecting rod 207 to vibrate, causing the scraper 208 to continuously reciprocate. Since the upper end of the scraper 208 is attached to the filter assembly 1, the scraper 208 can scrape off the debris attached to the surface of the filter assembly 1, effectively removing the metal debris and particles attached to the surface of the filter assembly 1, avoiding clogging of the filter assembly 1, reducing the frequency of manual cleaning, optimizing the liquid recovery efficiency, and extending the service life of the filter assembly 1.

[0033] Furthermore, the left-right vibrating scraper 208 and the rotation of the line-gap filter element 103 form an orthogonal motion trajectory. The reciprocating vibration of the scraper 208 disrupts the adhesion between impurities on the surface of the line-gap filter element 103 and the line-gap filter element 103 through periodic impact, which significantly improves the peeling efficiency, especially for high-viscosity or hard particles. At the same time, the microbubbles generated by the vibration burst, similar to the ultrasonic cavitation effect, can penetrate into the filter gap and enhance the ability to remove small particles.

[0034] In some embodiments of the present invention described above, a permanent magnet 211 is fixedly connected to the side of the fixed plate 204 near the slide rail 202, a connecting frame 212 is fixedly connected to the side wall of the sliding block 205, and a metal block 213 is fixedly connected to the end of the connecting frame 212 near the fixed plate 204, with the metal block 213 facing the permanent magnet 211.

[0035] Furthermore, during the vibration of the sliding block 205, the metal block 213 is attracted by the adsorption force generated by the permanent magnet 211, which, together with the spring 206, simultaneously counteracts the viscous resistance of the cutting fluid, reduces energy loss during vibration, and ensures that the scraper 208 can still maintain reliable reciprocating motion during vibration, thereby improving the cleaning efficiency and reliability of the scraper 208 on the filter assembly 1.

[0036] In some embodiments of this utility model, the filter assembly 1 includes a liquid storage tank 101, a second motor 102, a wire-gap filter element 103, and a purified liquid tank 104. The second motor 102 is fixedly installed on one side wall of the liquid storage tank 101. The wire-gap filter element 103 is rotatably connected to the inner wall of the liquid storage tank 101. The output end of the wire-gap filter element 103 penetrates through the side wall of the liquid storage tank 101 and is connected to the outside. The purified liquid tank 104 is fixedly connected to the lower part of the outer wall of the liquid storage tank 101. The output end of the second motor 102 penetrates through the side wall of the liquid storage tank 101 and is fixedly connected to one side of the wire-gap filter element 103.

[0037] A liquid pump 105 is fixedly installed on one side of the clean liquid tank 104. The input end of the liquid pump 105 is connected to a delivery pipe 106. The input end of the delivery pipe 106 is connected to the output end of the wire gap filter element 103. The output end of the liquid pump 105 is connected to the inside of the clean liquid tank 104.

[0038] Furthermore, by pouring the cutting fluid into the reservoir 101, with one side of the bottom of the inner wall of the reservoir 101 tilted, the output of the second motor 102 drives the wire-gap filter element 103 to rotate. Then, the pump 105 starts working, and the suction generated by the pump 105 creates a negative pressure inside the wire-gap filter element 103. The cutting fluid flows on the outer surface of the wire-gap filter element 103, which traps solid impurities such as metal shavings. The cleaning liquid enters the inner cavity of the wire-gap filter element 103 and is pumped by the pump 105 into the clean liquid tank 104, thus completing the filtration of the cutting fluid. Both the reservoir 101 and the clean liquid tank 104 are connected to a drain pipe on one side, and a valve is installed in the drain pipe. The drain pipe, in conjunction with the valve, is used to drain the dirt in the reservoir 101 and the clean liquid tank 104, making it convenient for the user to clean the reservoir 101 and the clean liquid tank 104 later.

[0039] It should be noted that the support shell 201 and the slide rail 202 are both fixedly installed on the upper end of the liquid storage tank 101, the upright plate 203 and the fixing plate 204 are both fixedly installed on the upper end of the liquid storage tank 101, and the upper end of the scraper 208 is attached to the lower end of the outside of the wire gap filter element 103.

[0040] In some embodiments of this utility model, a sewage discharge assembly 3 is also included. The sewage discharge assembly 3 includes multiple rotating rods 301, two sets of sprockets 302, two chains 303, multiple cleaning plates 304, and a third motor 305. The multiple rotating rods 301 are rotatably connected to the inner wall of the liquid storage tank 101. The number of sprockets 302 in each set is the same as the number of rotating rods 301. Each set of sprockets 302 is fixedly connected to one side of the outer wall of the multiple rotating rods 301. The two sets of sprockets 302 are symmetrically arranged. The two chains 303 are respectively sleeved on the outside of the two sets of sprockets 302, and the two chains 303 are used to drive the two sets of sprockets 302 to rotate. The third motor 305 is fixedly connected to... On the outer wall of the liquid storage tank 101, the output end of the third motor 305 is fixedly connected to one end of one of the rotating rods 301. Multiple cleaning plates 304 are fixedly connected inside the two chains 303, and the surface of the cleaning plates 304 is provided with multiple drain holes. When the cleaning plates 304 rise along the inclined surface of the liquid storage tank 101, the cleaning plates 304 discharge the settled debris from the liquid storage tank 101, while the liquid flows back into the liquid storage tank 101 through the drain holes. When the output end of the third motor 305 rotates, it can drive the chain 303 to move, thereby causing the cleaning plates 304 to move, so that the debris settled at the bottom of the liquid storage tank 101 can be discharged from one side of the liquid storage tank 101.

[0041] Example 1:

[0042] The line-gap negative pressure chip removal filter device provided by this utility model, during the process of the filter assembly 1 treating cutting fluid, the output end of the first motor 209 drives the elliptical plate 210 to rotate inside the support shell 201. The outer wall of the elliptical plate 210 continuously impacts the side wall of the sliding block 205. Since one end of the sliding block 205 is limited by a spring 206, the sliding block 205 continuously reciprocates on the upper end of the slide rail 202, which causes the scraper 208 to continuously reciprocate. Since the upper end of the scraper 208 is attached to the filter assembly 1, the scraper 208 can scrape off the debris attached to the surface of the filter assembly 1, effectively peeling off the debris. Metal debris and particulate matter adhering to the surface of filter element 1 prevent clogging, reduce the frequency of manual cleaning, optimize liquid recovery efficiency, and extend the service life of filter element 1. The left-right vibrating scraper 208 and the rotation of the line-gap filter element 103 form an orthogonal motion trajectory. The reciprocating vibration of the scraper 208 breaks the adhesion between impurities on the surface of the line-gap filter element 103 and the line-gap filter element 103 through periodic impact, which significantly improves the peeling efficiency, especially for high-viscosity or hard particles. At the same time, the microbubbles generated by the vibration burst, similar to the ultrasonic cavitation effect, can penetrate into the filter gap and enhance the removal ability of small particles.

[0043] Example 2:

[0044] The difference between this embodiment 2 and embodiment 1 is that during the vibration of the sliding block 205, the metal block 213 is attracted by the adsorption force generated by the permanent magnet 211. During the process of the spring 206 pushing the sliding block 205 to reset, the adsorption force of the permanent magnet 211, together with the elastic force of the spring 206, simultaneously counteracts the viscous resistance of the cutting fluid, reduces the energy loss during the vibration process, and ensures that the scraper 208 can still maintain reliable reciprocating motion during vibration, thereby improving the cleaning efficiency and reliability of the scraper 208 on the filter assembly 1.
