Description
Technical Field
[0001] This utility model relates to the field of emulsion filtration, and in particular to a filter for machine tool emulsions. Background Technology
[0002] In the field of machining, machine tool emulsions (coolants) are widely used to lubricate and cool cutting tools and workpieces, and to remove metal chips and abrasive powders generated during machining. During use, the emulsion will mix with a large number of impurities, including metal chips, powders and oil stains. These impurities will significantly reduce the performance of the emulsion, leading to decreased machining accuracy, accelerated tool wear, and even blockage of cooling system pipes, affecting the normal operation of the machine tool. Therefore, the emulsion must be continuously filtered and purified. Traditional filtration methods often use a single filter screen to filter emulsions. However, when processing emulsions, the filter screen is easily clogged by iron filings generated during machining, leading to a decrease in filtration efficiency. This requires frequent machine shutdowns for cleaning or replacement of the filter screen, affecting production continuity. Furthermore, single-screen filtration can only filter iron filings from the emulsion, and its filtration efficiency for fine impurities and solid particles in the emulsion is poor. Therefore, a filter for machine tool emulsions is proposed. Utility Model Content
[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a filter for machine tool emulsions. This filter uses an inclined pinhole screen to filter iron filings from the emulsion. A linear motor-driven cleaning scraper and electromagnetic adsorption rod automatically clean the screen and adsorb ferromagnetic impurities, effectively preventing clogging. Furthermore, an automatically rewinding and cleaning non-woven filter paper further filters solid particles and fine impurities from the emulsion, significantly improving filtration efficiency and continuity. This effectively solves the problems in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter for machine tool emulsions, comprising a filter box and a filter unit: Filter box: A waste bin is connected to the top of the right side, and a waste residue bin is connected to the bottom of the right side of the filter box. A box cover is hinged to the top of the filter box, and an inlet pipe is fixed to the surface of the box cover. A drain pipe is fixed to the bottom of the left side of the filter box. Conveying troughs are opened on both the left and right sides of the filter box. Filter unit: includes a mesh frame, a pinhole filter, a frame, a placement roller, a clip, and a fixing plate. The mesh frame is inclined inside the filter box with its left side lower than its right side. The pinhole filter is snapped into the through groove on the surface of the mesh frame. The frame is fixed to the left side of the filter box. The through hole on the front side of the frame is slidably inserted into the placement roller. The front end of the placement roller is rotatably installed in the middle of the rear side of the fixing plate. The clip on the rear side of the fixing plate is snapped into the corresponding groove on the surface of the frame. It also includes a controller, which is located on the front side of the filter box, and the input terminal of the controller is electrically connected to the output terminal of an external power supply.
[0005] The pinhole filter inside the inclined mesh frame can filter out larger impurities such as iron filings in the emulsion, while the card holder inserts into the card slot to place the non-woven filter paper on the outside of the placement roller. This can further filter out solid particles and fine impurities in the emulsion, thereby significantly improving the filtration effect and continuity of the emulsion.
[0006] Furthermore, the filtration unit also includes a placement rack, baffles, a linear motor, a cleaning scraper, connecting rods, a magnetic plate, and an electromagnetic rod. The placement rack is fixed to the rear side inside the filter box and waste box. A linear motor is installed inside the placement rack, and the bottom surface of the linear motor's actuator is connected to the rear end of the cleaning scraper. The cleaning scraper is in contact with the surface of the pinhole filter screen. Baffles are fixed to both the front and rear sides of the cleaning scraper. There are two connecting rods, which are fixed to the left side of the cleaning scraper, one in front and one behind. The bottom ends of the two connecting rods are respectively connected to the magnetic plate. The top surface is connected to both sides, and an electromagnetic rod is snapped onto the top surface of the magnetic suction plate. The input end of the linear motor and the electromagnetic rod are electrically connected to the output end of the controller. When the linear motor is started, it drives the cleaning scraper to scrape and clean the iron filings on the surface of the pinhole filter. The baffle can effectively prevent iron filings from splashing during the scraping process. When the electromagnetic rod is energized, it causes the magnetic suction plate to generate magnetism and adsorb and clean the iron filings stuck inside the pinhole filter. This achieves dual purification of physical filtration and magnetic adsorption to prevent the pinhole filter from becoming clogged and affecting the subsequent filtration effect.
[0007] Furthermore, the filtration unit also includes guide rollers, limiting plates, motors, frames, and take-up rollers. There are two guide rollers, rotatably mounted on opposite sides inside the filter box. The limiting plates are fixed to the front and rear sides inside the filter box, located below the guide rollers. The frame is fixed to the rear side of the waste bin, and a motor is mounted on its surface. The motor's output shaft passes through a through-hole on the rear side of the waste bin and connects to the rear end of the take-up roller. The motor's input is electrically connected to the controller's output. The guide rollers, in conjunction with the limiting plates, limit the movement of the non-woven filter paper and, by starting the motor, drive the take-up roller to rotate and roll up the old non-woven filter paper that has been saturated with impurities. Simultaneously, new non-woven filter paper is unrolled, achieving automatic renewal and thus improving the efficiency of emulsion filtration.
[0008] Furthermore, the filter unit also includes a fixed base, a spring, a sliding plate, and a cleaning scraper. The fixed base is fixed to the rear side inside the waste residue box. A spring is fixedly installed inside the fixed base. The bottom end of the spring is connected to the top surface of the sliding plate. The sliding plate is slidably installed inside the fixed base. A cleaning scraper is provided at the front end of the sliding plate. When the spring contracts, it causes the sliding plate to slide inside the fixed base, automatically adhering the cleaning scraper to the surface of the non-woven filter paper, thereby scraping away impurities.
[0009] Furthermore, the filtration unit also includes transparent windows, collection boxes, and handles. There are two transparent windows, which are respectively installed on the surfaces of the waste bin and the slag bin. There are two collection boxes, which are respectively slidably installed in the grooves on the surfaces of the waste bin and the slag bin. The surface of the collection box is fixed with a handle. The slidably installed collection box facilitates the collection of waste that has fallen during cleaning, while the installed transparent windows allow operators to intuitively observe the accumulation of waste and slag inside, facilitating timely cleaning.
[0010] Furthermore, it also includes a liquid level sensor, which is fixed to the bottom of the front side of the filter box. The output of the liquid level sensor is electrically connected to the input of the controller. The liquid level sensor can detect the remaining amount of emulsion after filtration inside the filter box, thereby facilitating subsequent recycling.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This filter for machine tool emulsions has the following advantages: 1. The pinhole filter inside the inclined mesh frame can filter out larger impurities such as iron filings in the emulsion. The card holder is inserted into the card slot to place the non-woven filter paper on the outside of the placement roller. This can further filter out solid particles and fine impurities in the emulsion, thereby significantly improving the filtration effect and continuity of the emulsion.
[0012] 2. By starting a linear motor, the cleaning scraper is driven to scrape and clean the iron filings on the surface of the pinhole filter. The baffle can effectively prevent iron filings from flying during the scraping process. The electromagnetic rod is energized to make the magnetic plate magnetic, which adsorbs and cleans the iron filings stuck inside the pinhole filter. This achieves dual purification of physical filtration and magnetic adsorption, so as to prevent the pinhole filter from becoming clogged and affecting the subsequent filtration effect.
[0013] 3. The guide roller and the limiting plate limit the non-woven filter paper, and the motor drives the winding roller to rotate to roll up the old non-woven filter paper that has been saturated with impurities. At the same time, the new non-woven filter paper is unfolded to realize automatic renewal, thereby improving the efficiency of emulsion filtration. Attached Figure Description

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.
[0021] Please see Figure 1-5 This embodiment provides a technical solution: a filter for machine tool emulsion, comprising a filter box 1 and a filter unit 2. Filter box 1: A waste bin 5 is connected to the top of the right side, a waste residue bin 6 is connected to the bottom of the right side of filter box 1, a box cover 3 is hinged to the top of the filter box 1, an inlet pipe 4 is fixed to the surface of the box cover 3, a drain pipe is fixed to the bottom of the left side of filter box 1, and a conveying trough is opened on both the left and right sides of filter box 1. Filter unit 2 includes a mesh frame 21, a pinhole filter 22, a frame 23, a placement roller 24, a clip 25, and a fixing plate 26. The mesh frame 21 is inclined inside the filter box 1 with its left side lower than its right side. The pinhole filter 22 is snapped into the through groove on the surface of the mesh frame 21. The frame 23 is fixed to the left side of the filter box 1. The through hole on the front side of the frame 23 is slidably inserted into the placement roller 24. The front end of the placement roller 24 is rotatably installed in the middle of the rear side of the fixing plate 26. The clip 25 on the rear side of the fixing plate 26 is snapped into the corresponding groove on the surface of the frame 23. Filter unit 2 also includes a placement rack 27, a baffle 28, a linear motor 29, a cleaning scraper 210, a connecting rod 211, a magnetic plate 212, and an electromagnetic rod 213. The placement rack 27 is fixed to the filter box 1 and the waste bin. Inside the rear side of the 5th internal storage rack 27, a linear motor 29 is installed. The bottom surface of the linear motor 29's actuator is connected to the rear end of the cleaning scraper 210. The cleaning scraper 210 is in contact with the surface of the pinhole filter 22. Baffles 28 are fixed on both the front and rear sides of the cleaning scraper 210. Two connecting rods 211 are fixed to the left side of the cleaning scraper 210, with their bottom ends connected to the two sides of the top surface of the magnetic plate 212. An electromagnetic rod 213 is snapped onto the top surface of the magnetic plate 212. The input ends of the linear motor 29 and the electromagnetic rod 213 are electrically connected to the output end of the controller 8. When the linear motor 29 is started, it drives the cleaning scraper 210 to scrape and clean the iron filings on the surface of the pinhole filter 22. The baffles 28 can prevent iron filings from being scraped off. During the cleaning process, iron filings are effectively prevented from flying during scraping. The electromagnetic rod 213, when energized, causes the magnetic plate 212 to generate magnetism, attracting and cleaning the iron filings stuck inside the pinhole filter 22.

The output shaft passes through the through hole on the rear side of the waste residue box 6 and connects to the rear end of the take-up roller 218. The input end of the motor 216 is electrically connected to the output end of the controller 8. The guide roller 214, together with the limiting plate 215, plays a limiting role for the non-woven filter paper. The motor 216 is started to drive the take-up roller 218 to rotate and roll up the old non-woven filter paper that has been saturated with impurities. At the same time, new non-woven filter paper is unfolded to realize automatic renewal, thereby improving the efficiency of emulsion filtration. The filter unit 2 also includes a fixed seat 219, a spring 220, a sliding plate 221 and a cleaning scraper 222. The fixed seat 219 is fixed inside the rear side of the waste residue box 6. The spring 220 is fixedly installed inside the fixed seat 219. The bottom end of the spring 220 is connected to the top surface of the sliding plate 221.The sliding plate 221 is slidably installed inside the fixed base 219. A cleaning scraper 222 is provided at the front end of the sliding plate 221. The spring 220 retracts, causing the sliding plate 221 to slide inside the fixed base 219, automatically attaching the cleaning scraper 222 to the surface of the non-woven filter paper, thereby scraping away impurities. The filter unit 2 also includes a transparent window 223, a collection box 224, and a handle 225. There are two transparent windows 223, respectively installed on the surfaces of the waste bin 5 and the waste residue bin 6. There are two collection boxes 224, respectively slidably installed in the grooves on the surfaces of the waste bin 5 and the waste residue bin 6. A handle 225 is fixed to the surface of the collection box 224. The slidably installed collection box 224 facilitates the collection of waste materials that fall during cleaning, while the installed transparent windows allow operators to visually observe the accumulation of waste materials and residue inside, facilitating timely cleaning. The system also includes a controller 8, which is located on the front side of the filter box 1. The input of the controller 8 is electrically connected to the output of an external power supply. The pinhole filter 22 inside the inclined mesh frame 21 can filter larger impurities such as iron filings in the emulsion. The card holder 25 is inserted into the card slot to place the non-woven filter paper on the outside of the placement roller 24, which can further filter solid particles and fine impurities in the emulsion, thereby significantly improving the filtration effect and continuity of the emulsion. The system also includes a liquid level sensor 7, which is fixed at the bottom of the front side of the filter box 1. The output of the liquid level sensor 7 is electrically connected to the input of the controller 8. The liquid level sensor 7 can detect the remaining amount of emulsion after filtration inside the filter box 1, thereby facilitating subsequent recycling.
[0022] The working principle of the filter for machine tool emulsion provided by this utility model is as follows: First, non-woven filter paper is placed on the outside of the placement roller 24. The card holder 25 is inserted into the card slot to install the non-woven filter paper inside the frame 23. The emulsion generated by turning enters the filter box 1 through the inlet pipe 4. The pinhole filter 22 inside the inclined mesh frame 21 can filter larger impurities such as iron filings in the emulsion. The linear motor 29 is started to drive the cleaning scraper 210 to scrape and clean the iron filings on the surface of the pinhole filter 22. The baffle 28 can effectively prevent iron filings from splashing during the scraping process. The electromagnetic rod 213 is energized to make the magnetic plate 212 generate magnetism to attract and clean the iron filings stuck inside the pinhole filter 22. This achieves dual purification of physical filtration and magnetic adsorption to prevent the pinhole filter 22 from becoming clogged and affecting the subsequent process. Continuing the filtration effect, the scraped iron filings fall into the collection box 224 inside the waste bin 5. At the same time, the guide roller 214, together with the limiting plate 215, limits the non-woven filter paper. The motor 216 is started to drive the winding roller 218 to rotate and roll up the old non-woven filter paper that has been saturated with impurities. At the same time, new non-woven filter paper is unfolded to realize automatic renewal, thereby improving the efficiency of emulsion filtration. The spring 220 contracts and causes the sliding plate 221 to slide inside the fixed seat 219, which automatically attaches the cleaning scraper 222 to the surface of the non-woven filter paper to scrape off the impurities. The scraped impurities fall into the collection box 224 inside the waste bin 6 for collection, reducing the time and effort required for manual cleaning. The liquid level sensor 7 can detect the remaining amount of emulsion after filtration inside the filter box 1, which facilitates subsequent recycling.
